Title: Combined bagging and packaging machine and method
IPC: B65B9/08
Filed: 1961-11-16
Abstract: 1,002,335. Packaging machines. PHILLIPS PETROLEUM CO. Nov. 16, 1961 [Sept. 7, 1961], No. 41126/61. Heading B8C. [Also in Division B5] A packaging machine comprises a roller 38 driven intermittently by means of a rack 61 and hydraulic piston 63, for supplying from a roll 25 predetermined lengths of sheet material 24 folded longitudinally to form a closed end 27, reciprocable jaws 97, 100 (see Division B5) for sealing and severing the folded sheet transversely after the operator has inserted an article to be packaged, and further jaws 114, 135, Fig. 8, which seal the open end of the package simultaneously with the transverse sealing and severing. The operator starts each cycle of the machine by means of a press button in an electrical circuit. The sheet material, which may be of plastics such as polyethylene or polypropylene, is drawn from the roll 25 until the upper end 70 of an adjustable rod 66 movable with the rack 61 contacts a control vent, Fig. 3 (not shown), thereby reversing the piston 63. The folded sheet passes either side of spreaders 78, 79, an eliminator 83 removing static electricity in the sheet. The transverse seal S is effected automatically in response to the action of rod 66, a piston 167 causing both the jaws 97 and 100 to move inwards. After the operator has inserted the article to be packaged, he starts a further cycle of the machine, the filled but unsealed package being thereby lowered below the level of the jaws 97, 100 and sealed both transversely and longitudinally. The jaws 114, 135 are secured below the jaws 97, 100, and after the package is both sealed and severed, a trigger mechanism effects the automatic withdrawal of both sets of jaws. Guards, e.g. 116, cause the jaws to reverse if they meet an obstruction. Surplus material is clamped between a blade 138 and arm 145. In a modification, Fig. 5 (not shown), a photoelectric cell is adjustably mounted in association with the spreaders 78, 79 and, on registering opaque areas on the sheet material, the cell effects the return of piston 63. In a further embodiment, Figs. 21-24 (not shown), the axis of the machine is inclined.

Abstract: 967,486. Photographic cameras. EASTMAN KODAK CO. Nov. 1, 1962 [Nov. 2, 1961] No. 41414/62. Heading G2A. On attaching to a photographic camera an interchangeable objective having a device representing its maximum aperture, a sensing member on a movably mounted measuring instrument having a pointer deflectable as a function of scene brightness is engaged the said device on the objective and adjusts the position of the measuring instrument accordingly. As shown the sensing member is a rod 19 which engages in a recess on the objective of a depth representative of the maximum aperture of the objective. The movement of the rod 19 on attaching the objective is transmitted by levers 17, 18 and a slide 16 to a plate 7 which is free rotatable on the journal 9a of the exposure meter galvanometer 9 and on which is rotatably mounted a gear 3 meshing with a gear 8 on the journal of the galvanometer 9. Movement of the plate 7 thus rotates the galvanometer but since the aperture scale bearing member 14 is also rotated by the plate 7 no change in indication occurs. A spring-tensioned cable 1 which is driven from an exposure setting device, e.g. for shutter and film speed, rotates a pulley 2 keyed to the gear 3 and so rotates the galvanometer 9 but under these conditions the scale member 14 does not move. Spring connected scale limit members 12,13 engaging lugs on the galvanometer 9 and fixed to the camera casing are freely mounted on the galvanometer journal 9a.

Title: Power-assisted steering mechanism for motor vehicles
Inventor: JENVEY LESLIE RICHARD
IPC: B62D5/093
Filed: 1969-08-19
Abstract: 1275460 Power-assisted steering ADWEST ENG Ltd 19 Nov 1970 [19 Aug 1969] 41434/69 Heading B7H A power-assisted steering mechanism for a  motor vehicle includes a double-acting power-  assist piston-and-cylinder 1, opposite ends of  which can be connected to a source of fluid under  pressure, e.g. an engine-driven pump 6, under  the control of a valve 7, and a separate closed  hydrostatic circuit which includes a positive displacement pump/motor 10 which is rotated by the steering wheel and a second piston-andcylinder which moves the movable part of the valve 7. The motor 1 consists of a cylinder 8 connected to the vehicle chassis by a ball joint 2 and a piston 17 having a piston-rod 18 connected to the steerable wheels by a ball joint 3 and linkage (not shown). The valve 7 has a movable spool 21 which, when displaced from its central neutral position, supplies pressure fluid from pump 6 and line 5 to port 24 or 25 depending on which way the spool 21 is moved. The spool 21 is connected to the piston-rod 20 of a piston 19 which is movable in a cylinder formed by the hollow piston-rod 18. The pistonrod 20 is hollow and contains a concentric tube 23. The tube 23 connects one side of the pump/ motor 10 to the left side of piston 19 via duct 11 and port 13 and the annular passage 23a between the piston-rod 20 and tube 23 connects the other side of the pump/motor 10 to the right side of piston 19 via duct 12, port 14 and bore 23b. Thus movement of the steering wheel operates pump 10 to move piston 19 and thus valve spool 21 to the left or right. This in turn supplies pressure fluid to the left or right of piston 17 to move the wheels. The spool 21 is biased towards its neutral position by sets of springs 30 and centralizing pistons 29 or by springs alone (not shown). This arrangement provides a definite positive relationship between the angular disposition of the steering wheel and the position of power assist piston 17 in its cylinder 8 and provides "feel".

Title: Hydrogen peroxide decomposition
IPC: C06D5/04
Filed: 1960-12-05
Abstract: An oxidant for use in liquid fuel rocket motors consists essentially of hydrogen peroxide of 30-100% by weight strength containing per litre from 50 to 750 milligrams (calculated as carbon) of an organic residue from the production of hydrogen peroxide from organic compounds or from the reaction of hydrogen peroxide or organic compounds. The residue probably contains organic peroxides and/or hydroperoxides and may be obtained in the production of hydrogen peroxide by the process using an alkyl anthraquinone described in U.S.A. Specification 2,158,525, a secondary alcohol as described in Specification 708,339, primary alcohols as described in U.S.A. Specification 2,479,111, hydrocarbons as described in Specification 540,534, or hydrocarbons as described in Canadian Specification 539,369. The invention also includes the decomposition of hydrogen peroxide by contact with a solid catalyst in the presence of 50-10,000 milligrams per litre of the organic residue specified above. The hydrogen peroxide may be passed through a bed of silver catalyst as described in Specification 780,342, or in U.S.A. Specification 2,721,788. The residue may be incorporated in the hydrogen peroxide before feeding to the decomposer or may be added separately to the decomposer, for example during start-up only. The mixture of oxygen and steam formed is fed to a combustion zone for reaction with the fuel.  Examples describe the decomposition under pressure of electrolytic 90% hydrogen peroxide containing the organic residue by contact with silver wire catalyst and show an increased rate of oxygen evolution, a faster rise in temperature, and improved starting at low temperatures as compared with hydrogen peroxide not containing the residue.
