Title: Photographic cameras
IPC: G03B17/42
Filed: 1961-12-01
Abstract: 1,013,433. Photographic role-film cameras. PENTACON DRESDEN KAMERA-UND VEB KINOWERKE. Dec. 1, 1961, No. 43070/61. Heading G2A. In a photographic roll-film camera wherein an electric motor advances the film and cocks the shutter, the current to the motor is supplied initially by contacts operated by the shutter in its run-down position and is maintained by contacts operated by the film-winding gearing until the correct amount of film has been advanced, and the shutter cocking is effected by a rack drive system which is operated by a toothed wheel mounted loosely on a spindle of a gear connected to the film-wind gearing and is coupled with the spindle for shuttle cocking by means of a pawl, the pawl being released by a stop at the end of the shutter cocking movement so that the rack can return to its original position under the action of a return spring. As shown in Fig. 1, the arm 64 of the shutter closes contacts 65 in the run-down position of the shutter (shown in chain lines) to energize the motor 2 (shown diagramatically) from the batteries 1. The motor drives shaft 4, and the take up spool 3 is driven through gears 5-16 and friction clutch 11, while the film and wind sprocket 38 is driven by gear 31 through gear 13. As soon as the motor commences to run, current is maintained by the closing of contacts 66 by an arm 67 engaging a cam surface 68 on the gear 31. The shutter is wound by a rack 21 which engages the gear 14 and is moved in the direction of the arrow against spring 24 so that the lug 25 engages the arm 64 to wind the shutter. The manner in which gear 14 is driven from gear 13 is shown in Fig. 2. The gear 14 is mounted loosely about a shaft 15 which carries the gear 13 and a disc 16. A pawl 17 is pivoted at 18 on the disc 16 and engages a tooth 20 in the boss of gear 14. Thus, in the position shown, the gear 14 is driven by the disc 16 and pawl 17 until the shutter is wound, when the pawl hits a stop 29 and is disengaged from the tooth 20 to allow the gear 14 and rack 21 to return to their initial position under the action of spring 24, the shutter being held in its cocked position by the release arm 62. Film-winding is arrested when the recess 40 on a disc 39, mounted on the spindle 32 of gear 31, comes up against the blocking arm 44 of lever 43 which is pivoted at 42 and urged into the position shown by spring 47. When the shutter release 57, is depressed the arm 49 engages the shutter release arm 62 and rod 48 pivots the blocking arm 44 out of the path of disc 39 so that the film-winding can commence. The arm 44 is prevented from returning to its blocking position by lug 55 which moves beneath it until it is moved away again by cam surface 41 when near the end of the winding operation. As arm 44 falls into its blocking position a brake pad 52 on arm 46 is applied to gear 6.

The amount of heavies produced may be reduced by adding a silane RSiHX2, where X is a hydrolysable group and R is a monovalent hydrocarbon group; this silane does not react with the nitrile.  A polymerization inhibitor may also be used, e.g. 2,6-di-tert-butyl-p-cresol, hydroquinone, tert-butyl-catechol, tert-butyl-4-methylphenol or 2,6-di-tert-butyl-4-methylphenol. Examples of alkene nitriles are acrylo-, methacrylo- and crotono-nitriles, allyl and methallyl cyanides, 1-cyano-4-pentene, 1-cyano-3-butene and 1-cyano-1-hexene.  The hydrolysable group in the silane may be halo, alkoxy, aryloxy or acetoxy.  The examples describe the preparation of beta-cyanoethyltrichlorosilane.  The tertiary disilyl amines may be prepared by reacting a monohalo-silane with a primary aliphatic amine (mol. ratio 1:3) in a solvent. Specification 847,805 is referred to.

Abstract: 1374016 Impact pulverizers; vibratory sifting apparatus BLEIBERGER BERGWERKSUNION 25 Sept 1972 44223/72 Headings B2A and B2H [Also in Division H1] In a process for dressing storage battery scrap by mechanically separating the lead-containing components, i.e. grid plates; grid forming paste, pole heads and pole binders, from the non-lead-containing components, i.e. casings and separators, the lids and bottoms of the casings are cut off, e.g. by a circular saw, without smashing the casings and the components are removed from the remainder of the casings and subsequently the non leadcontaining and the lead-containing components are separately dressed. As shown circular saw 4 cuts the lids and bottoms off the batteries 6 with the acid therefrom being collected at 5 and the components are then separated into the grid plate packages 8, the casing lids 9 which also include the pole heads and pole binders, and the casing bottoms 10 and the remainder of the casings 11. The grid plate packages 8 are processed by heating to 80-120C in through-type furnace 15 and breaking them up on vibrating screen 16, which comprises two halves 16' and 16" at the end of each of which is a suction device 17', 17" and a compressed air blower 18', 18". The relatively light-plastics separator pieces are removed by this suction along line 20 and an arrangement 19 is provided between the two halves of the screen to turn over the remaining component pieces. The coarse material from screen 16, i.e. whole and part grid plates with forming paste clinging thereto, are fed into impact breaker -12"' to separate the forming paste, which is collected -at 29, from the grid material collected at- 28. This separation may be uncessary if. classification into high and low antimony content alloys is not required. The casing lids 9 are also fed to an impact breaker 12' and the lead-containing components are separated therefrom at 9" by an air classification device 13. The lead-containing components from 9", 28 and 29 are supplied to the smelting unit 30 and the remaining components from 27, 9' and similarly broken-up bottoms and casing 10', 11' are disposed of together.

Title: Draughting machine
IPC: B43L13/02
Filed: 1966-10-04
Abstract: 1,117,800. Draughting machines. DATA RESOLVED TOOLS PTY. Ltd. Oct. 4, 1966 [Oct. 5, 1965], No.44267/66. Heading G1X. A draughting machine which is capable of producing from an orthographic view a "tipped" view as seen at an angle with respect to rotation about one of the axes of the orthographic view, or of producing views from a model or template or vice versa, comprises a table 11 with longitudinal guides 12 thereon, a carriage 13 movable along the guides 12, transverse guide means (not shown) on the carriage for guiding two pairs of members 27, 17 and 27, 18 for movement at right angles to the guides 12, tracer means e.g. a microscope 28 on one of each pair of members and print-out means 19 on the other and a rotational drive transmission between the members of each pair to produce the desired motion of the print-out means in response to tracing movements of the microscopes 28. Tracing movements of the microscopes 28 parallel to the guides 12 (X- direction) move the carriage 13 and are thus directly transferred to the print-out means 19. Movements of the microscopes transverse to this direction in one case represent movements in the Y-direction and in the other case movements in the Z-direction. These latter movements are transmitted by steel bands 30 to rotate shafts 32 coupled to the gearing which produces the desired movements of the print-out means 19 to produce the required "tipped" views. This is achieved by choosing the gear ratios to suit the particular view required the drive being effected through differential gears 38, 39 and toothed racks 35 on the members 17, 18. Also an extension of the member 17 carries a vertically movable slide 23 carrying a probe 24 which may be moved in X, Y and Z-directions over a model or template. Movements in the X-direction act on the carriage 13 direct and on movements in the Y-direction likewise act on the member 17. Movements in the vertical Z-direction act by way of a rack 46 on the slide 23 and through bevel gearing 49 to move the member 18. Thus orthographic views may be obtained from models or by replacing the probe 24 with a routing head with intermediate power amplification if necessary a model may be produced from drawings. The print-out means 19 may comprise a pen or pencil but as shown are constituted by sharp pointed members actuated by clappers on electromagnets 20 effective in marking metal.

Abstract: 1303013 Purifying I.C. engine exhaust gas GENERAL MOTORS CORP 23 Sept 1971 [28 Sept 1970 9 Nov 1970] 44381/71 Heading F1B An I.C. engine exhaust emission control system having a convertor for the exhaust gases which operates at or above a minimum temperature has a storage container for retaining untreated exhaust constituents and control means which is responsive to the temperature of the convertor or a time delay device responsive to the duration of the exhaust gas flow to direct the gas to the convertor to the container and vice versa. During the warming- up period the valve 30, Fig.1 diverts exhaust gas via passage 26 to container 34 which includes a filter 36 for retaining particulates, an adsorptive medium 38 for retaining hydrocarbons, an adsorptive material 40 for retaining carbon monoxide and absorptive material 42 for retaining oxides of nitrogen. The remaining exhaust gas passes out via fitting 44. When convertor 24 is at an efficient reaction temperature sensor 32 moves valve 30 to open outlet 28 and close passage 26 whilst opening valve 46. Induction passage vacuum draws air through fitting 44 and filter 50 to purge the exhaust gas constituents from the container 34 so that these pass through the engine to be reacted in the convertor 24. In another embodiment the container is purged by an air pump (54), Fig.3, (not shown), directly into an exhaust manifold upstream of the convertor and in a modification of this embodiment the air drawn through the container is previously heated by exhaust gas in an exchanger (62), Fig.5, (not shown). In another embodiment a valve 30, Fig.8 diverts exhaust gas to an expansible container 64 during the warm-up period. A passage 68, which may include pressure control valves connects container 64 to overflow container 34. The overflow container is omitted in another embodiment. In another embodiment exhaust gas from engine 110, Fig.10 passes via venturi 156 and catalyst bed 128 to passage 130. When the catalyst bed is below the reaction temperature a sensor 146 causes valve 144 to close the outlet passage and divert the gas along passage 138 and thereafter through a charcoal storage bed 140, chamber 132, holes 148 to outlet 136. At the reaction temperature the valve 144 is moved to the dotted line position to divert exhaust gas directly to outlet 136 whilst an air pump 150 assisted by the ejector 154, 156 purges the charcoal bed. Sensor 146 may be positioned to respond to the charcoal bed temperature or exhaust pipe temperature. In further modifications of the latter embodiment valve 144 may open automatically to relieve pressure or be replaced by a butterfly or poppet valve opened by a time delay which replaces the sensor.
