Title: Cameras and enlargers
IPC: G02B25/00
Filed: 1974-06-18
Abstract: 1458926 Copying cameras J R DENNER 23 May 1975 [18 June 1974] 27033/74 Heading G2A A camera or enlarger has a mirror and a support for the photo-sensitive material which are both alternately movable into and out of the light path through the lens; when the mirror is out of the light path, a viewing image is thrown directly on the support, and when the mirror is in the light path it reflects the light to the material on the support. As shown, the mirror and support are housed in an open-bottomed box 25 which fits into a camera body just above the lens. The support 2 is a plate of plastics material with a ground upper surface, which is mounted on pivots 4 so that it can move from a horizontal viewing position, Fig. 1, to a vertical exposure position, Fig. 2. A handle 22 acts as a balancing weight during such movement. In the Fig. 1 position, the support 2 is in the horizontal position, and the mirror 3, not required in this position, stands vertically along one side of the box. Light from lens 1 passes vertically upwards to fall on support 2, which may be transparent, to form a visible image for viewing purposes. In the Fig. 2 position, support 2 is pivoted downwards into a vertical position, a photo-sensitive sheet being held thereon by vacuum means. Mirror 3, carried by pivots 5, and supported by a constant tension spring 18 wound on a roller 28, is tilted into the diagonal position shown. Light passing upwards from lens 1 is now reflected to the sheet on support 2 to effect an exposure thereon, the mirror causing a lateral reversal of the image. A shield 29 prevents light passing directly to support 2, and a blind may be drawn across the top of the box during exposure to exclude stray light. Alternative arrangements of the support and the mirror can be seen in Figs. 5-8 (not shown).

Title: Improvements in or relating to the manufacture of soft or plastic centres for golf balls, and apparatus therefor
IPC: B29C31/06
Filed: 1930-09-11
Abstract: 361,465. Moulding golf balls. DUNLOP RUBBER CO., Ltd., 32, Osnaburgh Street, London, WILLSHAW, H., and COWLES, W. A., of Dunlop Rubber Co., Fort Dunlop, Erdington, Birmingham. Sept. 11, 1930, No. 27118. [Class 87 (ii).] Paste centres for golf balls are made by submitting the paste in bulk in a container 1 to pressure and delivering the paste in automatically measured quantities directly into the bags for containing it. The paste is placed in a hopper 13 from whence it is charged into the container 1 by vacuum or by applied pressure, by way of narrow slits 14 to facilitate de-aeration, a valve 13a being fitted to isolate the container when filled to the required level as judged by a gauge glass. The container is fitted with a pressure cylinder 4 whereby air pressure may be applied to the paste in the container either directly (in which case the air is filtered) or by means of a piston 7. A series of measuring devices are mounted on the container, each measuring device comprising a cylinder 21, Fig. 5, fitted with a three-way valve 18 and with a spring-pressed plunger 22 whose movement is limited by adjustable stops 30, 29. The valve in one position allows paste to be charged from the container 1 into the cylinder 21 against the pressure of the plunger, after which the valve is rotated to open communication between the cylinder 21 and a nozzle 19 to which the bag for the paste has been clamped as by a spring-pressed sleeve 55, Fig. 6. The plunger 22 may also be actuated in either or both directions mechanically as by a cam system, or by fluid pressure. The valves may be actuated in unison by a chain passing round sprockets 47 on the valve spindles, but a clutch 48 actuated by a hand-lever 49 may be interposed between the valves and valvedriving spindles to enable the valves to be manually controlled. The valve-driving chain 46, Fig. 1, is actuated by a rocking arm 43 controlled by a rod 41 which is reciprocated by pivoted arms 39, 40 carrying cam pieces 39b, 40b whereby the arms are rocked by a stop on a chain 37 driven through worm and chain gearing by a motor 34. When a piston 7 is fitted, a vacuum connection to the cylinder 4 below the piston is provided. When a piston 7 is omitted the cylinder head may be shaped to leave a narrow annulus 62, Fig. 8. which automatically shuts off the container when full, and no gauge glass is fitted in this case. The valves for controlling the pressure 59 and vacuum 60 may be interconnected.

Title: Improvements relating to the production of non-ferrous metals from substantially iron-free aqueous inorganic acid solutions containing the same
IPC: C22B3/00
Filed: 1950-11-08
Abstract: A process of recovering and separating nickel and cobalt from substantially iron-free inorganic acid solutions containing them, comprises the steps of concentrating the solution with ammonium salt of the acid corresponding to the anions in the solution e.g. sulphate and adding therewith sufficient ammonium ions to produce a pH of 4.5-6.7 and collecting the resulting nickel-bearing precipitated crystals, treating the remaining cobalt-bearing solution with sufficient ammonia to produce a pH of at least 6.8, treating the solution with a sulphur-free reducing gas until precipitation substantially ceases, and collecting the precipitated cobalt.  The nickel-bearing crystals may be redissolved in water, ammonia being added to produce a pH of at least 6.8, and the resulting solution is then treated with a sulphur-free reducing gas to precipitate metallic nickel.  The reducing gas used may be hydrogen or carbon monoxide or mixtures thereof.  At least a portion of the liquors remaining from the nickel and/or cobalt recovery steps may be recycled to provide ammonium salt for the initial step.

Title: Improvements in and relating to control gear for hydraulic forging presses
Inventor: TOWLER JOHN MAURICE
IPC: B21J9/12
Filed: 1953-10-12
Abstract: 782,892. Forging presses. ELECTRAULIC PRESSES, Ltd. Sept. 24, 1954 [Oct. 12, 1953], No. 27943/53. Class 83 (4). [Also in Group XXIX] A stroke control gear for an hydraulic press particularly a forging press causes the press platen to be stopped or reversed automatically when it reaches a predetermined point in its stroke corresponding to a predetermined thickness of the workpiece. The platen 2 carries hollow piston rods 5 with hollow control pistons 4 moving in control cylinders 3 mounted on the stationary press head 1 and maintained filled with liquid through pipes 37. As the platen descends liquid flows from the underside of the control pistons through ports 17 and orifices 9 to the upper sides thereof but the transfer of liquid ceases when the pistons engage adjustable plug valves 7. The liquid pressure below the control pistons is thus intensified and acts through pipes 23, which include safety valves 24, on plungers 22 operating in cylinders 21. The plungers actuate a compensating lever 25 acting on a second compensating lever 26, biased by a spring-loaded plunger 29, which actuates the main press control valve 6 thus stopping or reversing the platen. The plug valves 7 are carried by rods 8 having rack teeth 12 in mesh with pinions 11 which are actuated through a shaft 14 and worm gearing 13 by an hydraulic motor 15 controlled by a valve 16 for adjusting the plug valves and hence varying the stroke of the platen which is indicated on a dial 18 by pointers 19. The lever 25 which imparts to the lever 26 the mean displacement of the two plungers 22 compensates for any tilting of the platen. The lever 26 is fulcrumed at its left-hand end between a plunger 27 and a spring blade 28 supported by a longitudinally movable fulcrum 31 and a plunger 32 biased by pressure liquid admitted through a valve 36. The plunger 27 is subjected to the pressure existing in the main press cylinder and hence compensates for any stretch in the press columns or deflection of the platen which will be proportional to the pressure in the main cylinder. The effective resilience of the spring 28 is varied by moving the adjustable fulcrum 31. By operating the valve 36 to release pressure from the plunger 32 the operation of the control gear will be suppressed without disturbing its setting. Check valves 38 facilitate transfer of liquid from the top to the bottom of the control cylinders 3 during the upstroke of the platen.
