Title: Improvements in or relating to lens shutters
IPC: G03B9/22
Filed: 1961-08-03
Abstract: 944, 627. Photographic pivoted blade shutters. KABUSHIKI KAISHA HATTORI TOKEITEN. Aug. 3, 1961 [Aug. 3, 1960], No. 28260/61. Heading G2A. A camera lens shutter having separate sets of cover and exposure blades is constructed so that on operation of the shutter release the cover blades open before the exposure blades and remain latched open until exposure is completed when the cover blades are closed by the exposure blade master member, which is rotatable about a point not on the optical axis of the shutter, causing release of the cover blade latch. As shown the shutter comprises five exposure blades (not shown) operated by a rotatable blade ring 27 and five cover blades 39 pivoted on fixed pins 38 and carrying control pins 40 engaging in slots 37a in a blade ring 37. In Fig. 1 the cocking ring 3 has been moved to rotate through teeth 3b a pinion 14 coupled to the exposure blade master member 16 which is thereby rotated so that its drive spring 17 is tensioned, member 16 and ring 3 being latched in the positions shown by levers 18 and 6 respectively. When the shutter release lever 9 is depressed and so rotated anticlockwise first its arm 9a rotates lever 30 which by means of pin 35 moves lever 32 anticlockwise to rotate via pin 36 the cover blade ring 37 and so open the cover blades the ring 37 being latched by lever 41 to hold them open; secondly the pin 13 rotates the latch 6 to release ring 3 which is rotated anticlockwise by spring 4 taking pinion 14 with it, until finally pin 21 on the ring 3 engages lug 18a and rotates the latching lever 18 to release the master member 16. The master member lug 16b first rotates a lever 24 which engages a pin 28 on the exposure blade ring 27 to open the exposure blades and then engages a pin 29 on ring 27 to close the blades, and finally a pin 44 on the member 16 moves lever 41 to unlatch the cover, blade-ring 37 which is caused to rotate and close blades 39 by spring 33 if or when the operator lets go the trigger. A lug 16c is provided on member 16 to engage a shutter speed control governer (not shown). Unintentional opening of the exposure blades at the end of the exposure due to rebound tendencies is prevented by the concentric portion of the master member lug 16b (see Fig. 2) engaging the pin 29. The cocking ring 3 may also be arranged to operate when released by the trigger 9 a delay mechanism for synchronizing M type flash bulbs, flash synchronizing contacts, or a delayed action (selftimer) mechanism. If it is undesired to prevent operation of the trigger if the shutter has not been set an interlock may be provided although no unintentional exposure can be caused even in its absence. The shutter is arranged with the cover blades between the exposure blades and the objective diaphragm blades. For interchangeable objectives the shutter is arranged behind the objective.

Abstract: 469,529. Machine guns. SERVOFREIN DEWANDRE SOC. ANON. Oct. 19, 1936, No. 28349. Convention date, Oct. 17, 1936. [Class 92 (ii)] Relates to pneumatic devices for operating the trigger and safety locking mechanism of a machine gun, and consists in actuating the trigger pull-rod 21, Fig. 1, against the action of a spring 18 by a pneumatically-operated piston 9, a locking-bolt 42, actuated by a pneumatically-operated piston 30 being adapted to engage the rod 10 of the piston 9 to lock the rod 21 in the non-firing position. In the form shown, the piston 30, Fig. 2, is double-acting and is connected to the locking bolt 42 by a link 37 and lever 39. The admission of air under pressure to the side 31 of the piston under the control of a distributer (not shown) causes engagement of the locking-bolt as shown in Fig. 2 in a notch 44 of the rod 10. When air is admitted to the cylinder for recocking the striker c, a distributer is operated which also admits air to the side 32 of the piston 30 to release the bolt 42. The piston 30 is retained in its extreme positions by a spring catch 46 engaging notches 47, 48. A limited movement of the rod 21 against the action of a spring 20 is permitted when recocking the striker c into engagement with the sear a.

Abstract: 1,158,769. Bearings. STAUBLI & CO. GEBR. 20 June, 1967 [23 June, 1966], No. 28398/67. Heading F2A. A replaceable bearing half-shell 4 of synthetic plastics material is mounted in a bearing-block 3 so that, on radial removal of the bearing-block from a shaft 2, the half-shell 4 is retained in the block 3. The shaft 2 is rigidly secured between two walls 1 and the detachable unit comprising the half-shell 4 and the block 3 is rotatably mounted on the shaft 2. The bearing surface 8 of the half-shell 4 encircles the shaft 2 to slightly more than 180 degrees and terminates in lateral cheeks 7; and the outer surface of the half-shell 4 is shaped so as to fit into a depression 5 in the block 3, the depression being formed with undercut recesses 6 to retain the half-shell in position. When the half-shell is to be replaced, the unit is moved radially so that the lateral cheeks 7 are opened outwardly to allow disengagement with the shaft and to cause a tighter engagement of the half-shell in the recesses 6 of the block 3 and thus allow the latter to be removed from the shaft but still retain the halfshell in the depression. The half-shell is replaced and the unit is returned to support the shaft.

Title: Method of making fuel gas from hydrocarbon oils and steam
IPC: C10G9/00
Filed: 1933-10-17
Abstract: 417,734. Oil - gas generation. CARBURETTED GAS, Inc., 19, Dover Green, Dover, Delaware, U.S.A. Oct. 17, 1933, No. 28721. Convention date, June 6. [Class 55 (ii).] In the production of a carbon monoxidehydrogen gas mixture by the passage of steam and oil separately or together through a preheated porous bed 5 of refractory material in a generator 1, the steam reacts with carbon deposited on the bed from the passage of oil in a preparatory step and the oil is cracked so that only carbon monoxide and hydrogen are produced. In the preparatory steps of the process, the outlet valve 3 being closed and the valve in the stackpipe 9 open, air and oil are burnt in the generator, the gases passing to the stack, and oil is then introduced to the hot bed alone to effect a carbon deposit on the refractory material. Air is now passed into the generator for combustion with excess carbon, the temperature of the bed being raised to 2500‹ F. The bed is now ready for gas generation. The gas making step is stopped when the temperature of the bed is lowered to about 1850‹ F., to prevent dilution of the gas mixture with carbon dioxide, the bed reheated and the cycle is then repeated. The carbon monoxidehydrogen gas mixture may contain a predetermined quantity of fixed hydrocarbon gases by allowing the oil and steam to continue their passage through the hot bed after the temperature of the latter is lower than that required to crack the oil into its elements. The hydrocarbon gases collect in a tempering chamber 10 where they mix with the carbon monoxide-hydrogen gas mixture previously formed. The tempering chamber may be preheated with the generator during the preparatory steps of the process.

Title: Hydrocarbon Reforming process and apparatus
Inventor: GENT COLIN WILLIAM
IPC: C10G47/00
Filed: 1966-06-28
Abstract: 1,176,935. Making combustible gas. IMPERIAL CHEMICAL INDUSTRIES Ltd. 19 May, 1967 [28 June, 1966], No. 28974/66. Heading C5E. In a process, e.g. of the kind described in Specification 1,032,753, in which further hydrocarbon is reacted with a primary reformer gas and steam at high temperature over a catalyst to give a methane-containing gas, the average time elapsing between injection of the further hydrocarbon and contact with the catalyst is made short enough, e.g. less than 0À2 second, for less than 20% of the hydrocarbon to be thermally cracked before it reaches the catalyst. Thus carbon formation is prevented and the temperature of the mixture entering the catalyst is kept up. The path for the mixture between injection and catalyst is through passages narrow enough to produce homogeneous mixing due to turbulence. In one apparatus, Fig. 1, primary reformer gas at 750‹ C. enters at 12 and passes via tubes 26 to the catalystcontaining vessel 10, and a mixture of naphtha vapour and steam enters at 30 and passes via tubes 22, 26 to the vessel 10. In another embodiment, Fig. 3 (not shown), the naphthasteam mixture is injected at right angles into the inlets 12 which lead directly to a perforated cylinder (38) containing catalyst. Catalyst in ring form, e.g. as described in Specification 1,003,702 may be employed to complete the mixing, and may be overlaid by catalyst pellets. The injected further hydrocarbon may be feedstocks having a B.R. of 30‹ to 350‹ C., liquefied petroleum gases, and refinery gases, and in an example, the same feed, (straight-run distillate) was used for making the primary reformer gas and for injection thereinto.

Abstract: 854,624. Centrifugal pumps and compressors. SULZER FRERES S.A. Sept. 17, 1957 [Oct. 12, 1956], No. 29256/57. Class 110(1). In a rotary pump or compressor in which there is a guide-blade ring associated with each impeller, a chamber is provided between a guide-blade ring and a part adjoining it in the axial direction, the chamber communicating with a point at lower pressure than that of the medium flowing through the guide-blade ring, and the parts forming the chamber are sealed against each other in a manner permitting axial play. The reduced pressure in the chamber reduces the forces imposed on the pump or compressor housing by the pressure differentials acting on stator parts. In the double-flow pump shown, a chamber 12 is formed between a guide-blade ring 10 and an axially adjoining part, and chamber 15 and 16 are formed between a guide-blade ring 9 and axially adjacent parts on either side of it. The chambers are vented to atmosphere through passages 17, 18 and 19. Packing is provided between the parts forming each chamber, in a manner permitting axial play so that axial forces acting on one part are not transmitted to the other part. A similar construction is provided on the right-hand side of the pump, but an alternative arrangement, whereby passage 19<SP>1</SP> leads to the inlet 2 instead of to atmosphere is shown. In a modification, chambers 15 and 16 are omitted and chamber 12 is vented to the outlet side of the first stage. The pump may be of single-flow type.
