Author Topic: Washing Dolby 3D Glasses Manny Knowles "What are these things and WHY are they BLUE???" Posts: 4247 From: Bloomington, IN, USA Registered: Feb 2002 posted 02-08-2011 09:43 AM                     We have those new wire trays for the Dolby 3D glasses. These trays are different from the ones shown in the Dolby training video. The new trays can hold up to 48 pairs of the Cat 834 glasses, or 60 pairs of the new plastic Cat 830 glasses. And it looks like maybe 2 baskets can fit into the Knight commercial dishwasher. Has anybody had any luck stacking that many pairs of glasses neatly like in the promotional photograph? Ours are not stacking too nice. Looks like we have the older Cat 830 style. After about the 2nd or 3rd level, they start sliding all into each other. My concern is that they won't all get cleaned. Am I right to worry about this? (I haven't been able to test the washer yet because it was just installed and now I'm waiting for the ECO chemical dealers to make their site visit to finish setting it up.)  |  IP: Logged Sam D.

No. 832 glasses which is what you should have. the 830's were not intended for the USA cinemas. Long story not for discussion here. I'll find the notice and send it to you.  |  IP: Logged Mike Blakesley Film God Posts: 12767 From: Forsyth, Montana Registered: Jun 99 posted 02-08-2011 10:58 AM                        Sam - could you send that to me, too? We have those same trays and while they do work well, the glasses do tend to nest together.  |  IP: Logged Manny Knowles "What are these things and WHY are they BLUE???"

But seriously, Sam - any reason I get zero results when Googling "Dolby Cat 832" ? Mike - what have you been doing about the nesting situation? Do you stack fewer? or do you toss 'em in and let the washer somehow deal with the nesting? And does the washer really only take 3min to do the job?  |  IP: Logged Mike Blakesley Film God Posts: 12767 From: Forsyth, Montana Registered: Jun 99 posted 02-08-2011 05:29 PM                        We just stack 'em 4 deep on each side -- if you put them in carefully they'll usually stay up the way they're supposed to. The washer we have only takes about 90 seconds.

Are the lens the same? I dont care if it is only a matter of frame design. Presently I am using 834's but I want to go plastic. I can get either 830 or 832. Which one would you advise? Thanks.

Now what is CAT 830? Any pictures? And how does this fit in? http://www.marlinwire.com/docs/Dolby3D_PlasticReusableGlasses_Dealers.pdf - Carsten  |  IP: Logged Sam D.

The 834's will take more wash cycles but I don't recall the data.  |  IP: Logged Jack Bauer Film Handler Posts: 2 From: Villennes, Yvelines, France Registered: May 2011 posted 05-20-2011 08:27 AM                     My data: http://www.avsforum.com/avs-vb/showthread.php?p=20459886#post20459886 Do you agree?

Posts: 4247 From: Bloomington, IN, USA Registered: Feb 2002 posted 04-03-2012 01:38 PM                     I've noticed that calibrating the Knight (KLE-175GT) washer can be a bit tricky... The wash cycle re-uses the leftover water from the rinse cycle. And, after opening the washer, removing clean glasses and inserting used ones, the temperature of that water drops by about 10 degrees (F). This means that the rinse cycle needs to be around 130F in order for the wash cycle to be at 120F, which is the minimum for the chemicals to work. However, the glasses themselves (2 sets of 60pr) will cool the water by about 12F. So the rinse cycle (empty) needs to be around 140F. This translates to a rinse cycle around 130F with glasses loaded. The subsequent wash cycle (with glasses loaded) is around 120F. Anybody notice similar results with the Knight washer and the high-capacity trays (pictured in the original post) ? I'm going to measure the water temperature with a different thermometer, just to make sure that the built-in one is reading right. I've got a few at home that can be calibrated using boiling or iced water. (BTW my glasses don't look like any of the ones pictured in that last link.)  |  IP: Logged Carsten Kurz Film God Posts: 4340 From: Cologne, NRW, Germany Registered: Aug 2009 posted 04-03-2012 06:47 PM                     Can you attach a photo? - Carsten  |  IP: Logged Manny Knowles "What are these things and WHY are they BLUE???"

Posts: 4247 From: Bloomington, IN, USA Registered: Feb 2002 posted 04-03-2012 11:37 PM                     Haha -- we crossed in the cloud! ...and the Marlin Wire Website has been updated to state that the 834's are a "loose fit" in the 780004 basket, which is probably what I have. I'm curious about the other basket they have for the 834's (780006) -- so far, no pic on their site.  |  IP: Logged
