Patent GB-1299600-A (GB)
Title: A camera
IPC: G03B7/00
Filed: 1969-12-29
Abstract: 1299600 Photographic exposure control; reflex view-finders NIPPON KOGAKU K K 29 Dec 1969 [27 Dec 1968] 63116/69 Heading G2A A camera has an exposure control system for sensing light through the objective lens diaphragm aperture, means for maintaining the aperture at a predetermined value during exposure measurement for photo-taking aperture values equal to and smaller than the predetermined value, and means responsive to the making of an exposure measurement for a photo-taking aperture value greater than the predetermined value to adjust the aperture to said greater value, whereby at least part of said measurement takes place at said greater value. It is stated that this compensates for the under exposure that occurs at larger apertures. In Fig. 3, x indicates the diaphragm scale for a lens of maximum aperture f/1À4 and f/2 is the predetermined value for this lens. For f numbers greater than 2, scale x is moved left to shift a stop 1 (which rotates a galvanometer M) and to allow a diaphragm control 3 to attain a position 3<SP>1</SP> at which it abuts a stop 4 and maintains the aperture at f/2. On shutter release, stop 4 is shifted so that control 3 can run off to the preset value. Galvanometer M is also rotated by shutter and film speed dials T and S. For f numbers less than 2, scale x is shifted right (as shown) so that it moves control 3 to open the diaphragm to a value greater than the predetermined value. In Figs.8 and 10 the aperture is automatically set. Prior to shutter release diaphragm control 3 is at position 3<SP>1</SP> corresponding to the predetermined aperture value. On depressing the shutter release a cam 51 moves upwards and a member 52 connected thereto moves rightwards. If the light is such that an aperture smaller than the predetermined value will be required then cam 51 strikes a galvo pointer 8, and diaphragm control 3 remains at 3<SP>1</SP>. On further depression stop 4 is released and control 3 moves left until it abuts member 52. For apertures greater than the predetermined value, cam 51 misses pointer 8, and so member 52 keeps moving right striking control 3 to open the diaphragm until pointer 8 moves back and stops cam 51. In Fig. 12 (not shown), the aperture is automatically set and in Fig. 13 (not shown),- the shutter speed is automatically set, each of these embodiments comprising a bridge circuit including a photo-conductor and variable resistor(s). Reflex view-finders. In a number of cases view-finding will take place at apertures less than maximum and to compensate for this the camera may have inter-changeable focusing screens having different diffusion characteristics. Also it may be possible to open the aperture fully during viewfinding, the exposure control system being automatically switched off when this is done.

Title: Improvements in the Manufacture of Glass
IPC: C03B40/00
Filed: 1978-08-03
Abstract: In methods for forming glass articles wherein hot formable glass is first formed into a parison, or blank, which is formed into the final glass article in a blow mold and wherein there is no relative rotation of the glass and the molds in the forming operation; the improvement resides in providing the cavity-defining surface of the blank mold with a layer, or coating, of a solid film lubricant or glass release agent which essentially comprises a non-colloidal lubricating graphite dispersed in a thermoset, cured, hard organopolysiloxane binder. The layer, or coating, is formed by applying a dispersion of graphite in an organic solvent solution of a further-curable, thermosettable, solvent soluble, organopolysiloxane onto the cavity defining surface of the blank mold and then curing said organopolysiloxane to a thermoset hard condition.

Abstract: In a method of forming an end closure from portions of a wrapper projecting beyond an end of an article (20) to be wrapped comprising folding opposed side edge portions (10-1, 10-2) over the end of the article and folding, in sequence, opposed lower and upper edge portions (10-4, 10-3) over the article end, the upper edge portion (10-3) is folded upwardly while the side edge portions (10-1 10-2) are folded over the article end. End closures are formed simultaneously and in the same manner at opposed ends of the article. Apparatus for performing the method comprises an elevator (2) for lifting the article (20) and the wrapper (30) between supports (1) which fold the wrapper down over sides of the article. Thereafter members (3) advance to fold a portion of the wrapper under the article and a further portion of the wrapper is folded beneath the article upon the article being pushed off supports (1) by a pusher (6). Folders (such as 8, 11) fold in the side edge portions (10-1, 10-2) and fold up the upper edge portions (10-3). Further folders (14, 13) then fold the lower edge portions (10-4) over the article ends and return the upper edge portions to a horizontal position. The thus partially wrapped article is then transferred to an elevator (17) which raises it past folding members (16) to fold the upper edge portions (10-3) over the article ends. <IMAGE>

Title: Improvements in Paper Making Machinery
IPC: D21F7/00
Filed: 1980-06-27
Abstract: In a continuous paper making machine a fourdrinier wire 1 is supported on rolling gear comprising a cross member 2. A beam 20 is telescopically extendable from and retractable back into the member 2 and, when extended, is jacked up at its free end to allow one of the normal lateral supports 3 of the machine to be removed. A support is then provided at 8 for the rolling gear intermediate these supports 3 and 4 to enable the jack 21 to be removed leaving a free length of beam and rolling gear onto which the fourdrinier wire 1 can be inserted. The jack is then replaced to allow the intermediate support to be removed and the fourdrinier wire to be pushed wholly onto the rolling gear. The lateral support 3 can then be replaced, the jack 21 removed and the beam 20 retracted. Inserting the fourdrinier wire in this way involves less expense, disruption and machine downtime than do known arrangements. <IMAGE>

Title: Registering copy sheets prior to binding
IPC: B65H9/16
Filed: 1980-10-29
Abstract: An electrostatographic reproduction machine having a copy sheet registration arrangement which operates before a stapler (84) or stitcher is disclosed. Sheets which are transported to a collection station (82) are subject to two-step registration positioning. In the first step, the sheets are registered by side guide (94) and inclined belt and ball conveyor means (95) causing them to shift from a centerline of the paper path leaving the copier to a parallel centerline of the paper path to the collection station (82). In so shifting, they are coarse registered on an edge parallel to the centerlines, the edge being the "top" edge of each sheet as viewed when reading. In this manner, the registration is equally effective regardless of the various sizes copy sheets may take. A second "top" edge registration, which is more accurate, and a "side" edge registration are effected in the collection station (82) by an inclined scuffer wheel (162) cooperating with side registration guide (174) and end stops (128). <IMAGE>
