Title: Sliding-door latch
Inventor: KWONG SENG CHOY
IPC: B65D43/20
Filed: 1986-01-07
Abstract: A fowl/poultry crate or other container has an opening closed by a slidable door (6) formed centrally along one transverse edge with a recess (10) in which a latch (9) is installed. The latch (9) includes a resilient tongue (15) with a hook (18) at one end. The hook (18) can be urged into latching engagement with an abutment at one edge of the door opening by resilient deflection of an inclined surface (23), so that the hook (18) subsequently latches over the abutment. Manual pressure upon the lower (in Fig. 5) surface of the tongue (15) will deflect the hook (18) and allow the door (6) to be slid to a fully open position which is limited by a stop (19). The construction and arrangement are such that the latch (9) remains wholly within the thickness of the wall panel of which, during use, the door (6) forms a part so that, whilst being readily manually releasable, the closure (9) will not be accidently unfastened merely by, for example, a heavy article being placed on top of the crate or other container. <IMAGE>

Title: Door lock for an autoclave
Inventor: LANE ARTHUR GEORGE
IPC: E05C9/00
Filed: 1986-01-16
Abstract: A door lock for an autoclave comprises a handle 7 pivotable on an axle 8 journalled in bearing 9 and which engages with racks 12 on slide plates 11 via pinions 13. Slide plates 11 have apertures 16 and recesses 15 to engage behind the heads of bolts (not shown) provided adjacent a chamber opening, to lock the door shut at a plurality of positions with a single pivoting movement of handle 7. Latch 16 engages behind a plate when the handle 7 is closed and can be held there to prevent opening of the handle when the temperature or pressure in the chamber exceeds certain limits. An inner handle 29 behind handle 7 forms an over-centre toggle mechanism with a latch 27, the handle 29 and latch 27 respectively pivoting about axles 26, 28 in the door 1 and handle 29. Handle 29 moves from a closed position (Fig. 2) to a partially open position to allow the door to open, latch member 27 engaging a stop 32 to force the door to open if necessary. Further movement of the handle urges latch 27 against a spring 33 and releases it from a catch 31 to allow the door to be fully opened. <IMAGE>

Patent GB-2213079-A (GB)
Title: Grading/sorting grain or seed
Inventor: DRURY ROGER JOHN
IPC: B07B4/02
Filed: 1988-12-28
Abstract: Grains or seeds are projected each at the same velocity in a stream; the grain or seed is caught at a first or second catching site depending on the trajectory that it has followed. Grain/seed that has fallen at the first catching site is collected separately from that falling at the second catching site. The two catching sites may be separated by an adjustable divider to adjust the quality of grain/seed collected from the different catching sites. The grain/seed may be cleaned by an adjustable air flow directed counter to the path of the grain/seed. Optionally the apparatus may be adjustable to enable it to be used for a pre-cleaning run before the grain/seed is graded or sorted. Separation thus occurs on the basis of differences in specific gravity and may be employed to separate out grains which have commenced germination. In a practical embodiment of apparatus, grain or seed is supplied in a regulated stream to a rotary impeller (51, Fig. 2, not shown) that projects it into a free-flight chamber (61) having an adjustable divider (74). <IMAGE>
Patent GB-890634-A (GB)
IPC: G03D9/00
Abstract: 890,634. Copying devices. ZINDLER, W., [trading as LUMOPRINT ZINDLER KOMM.- GES.]. Feb. 12, 1960 [Feb. 24, 1959], No. 5136/60. Class 98(2). In a copying device for exposing an original on to a negative layer carrier which is then passed through a developing station together with a positive layer carrier for diffusion developing, said layer carriers are separated in at least a part of the developing station by a guide element extending in front of the developing station and having one or more apertures through which there extend pairs of rollers in co-operating relationship of the guide element for feeding the said layers. As shown in Fig. 1, the original and a negative layer carrier and for simplicity of operation, also a positive layer carrier are inserted through the opening 11 and guided by a guide 12 to be carried round the periphery of an exposure cylinder 2 containing a light source 6<SP>1</SP> by a belt, or belts, 7 passing over the three rollers 8, 9, 10, one of which at least is resiliently mounted to maintain the belt in tension, the exposure cylinder being supported in a convolution of the belt and imparting to it the drive from a driving mechanism. The original and the layer carriers are delivered out of the opening 11 whereupon the original is removed and the negative and positive layer carriers are inserted through opening 15 one on either side of a guide 16 and transported by rollers 9, 18 towards rollers 10, 17, the rollers extending through apertures in the guide 16, additional guiding being provided by plates 21, 22 (the latter also acting as a screen against light from the exposure cylinder 2), and then to the developing bath 3 and finally through the squeezing rollers 4, preferably both of which are driven, and out through the opening 5. The supply of liquid from a supply container 26 to the bath 3 is controlled by a lever system 31, 30, 29 operating an outlet valve 28. The supply container has an airtight inlet port, and a pump 35 connected to the container 26 by duct 34 enables all the liquid in the bath 3 to be withdrawn via sump 32 into the container 26 for mixing. The guide 16 extending through the bath 3 is perforated to facilitate the flow of liquid. The aperture in guide 16 for the pairs of rollers 9, 18, and 10, 17 tapers in width towards the bath 3 to facilitate separation of the layer carriers. In a further embodiment, the positive layer carrier is fed automatically from a pile of sheets into the developing bath synchronously with the arrival at the bath of a negative layer carrier which trips a stop lever to allow the feed of the positive layer carrier.
