Title: Improvements in or relating to motion picture cameras
IPC: G03B33/00
Filed: 1934-10-20
Abstract: 450,673. Colour kinematography; kinematograph cameras. BREWSTER, P. D., 28, Gillespie Avenue, Fair Haven, New Jersey, U.S.A. Oct. 20, 1934, No. 30053. [Class 97 (i)] Cameras for two or three separate films, one directly in front of a lens and the others displaced to left and right of it, have two intermeshing multiplebladed rotary mirrors and a rotary shutter enabling the exposures to be effected substantially simultaneously and uniformly over the entire surface of each film. As shown in Fig. 2, the camera-lens 4 forms one image on the film 5 in mechanism 6 through the filter 7, another image on the film 10 in mechanism 11 through the filter 9 by means of the mirror 8, and a third image on the film 14 in mechanism 15 through the filter 13 by means of the mirror 12. The mirror 12 is mounted on shaft 16 revolving in the swivel bearing 17 and adjustable bearing 18 and driven by gears 19 from the drive shaft 20. The mirror 8 is mounted on shaft 21 driven by gears 22 from shaft 22 and journalled in swivel bearing 23 and adjustable bearing 24. The camera is driven by the motor 25 by gearing 26, the idler gear 27 driving mechanisms 6 and 11 through gears 29, 28 respectively. The gear 29 drives the mechanism 15 through idler gear 30 and gear 31. The mirrors, shutter and magazines are driven through gears 34, shaft 35, gears 36, shaft 20 and gears 37. A shaft 39 is provided for hand drive. The magazine 43, Fig. 10, has a shaft 104 carrying a gear 105, feed sprocket 103, and take-up sprocket 108. When the magazine is in operative position the gear 105 engages a drive gear in the camera. The feed and take-up spools 101, 1.02 are coaxial, and the film 101a passes over sprocket 103, through guide 106 into the guide 107 in the mechanism 6, and is thence drawn into the magazine by sprocket 108. The mechanism 6, Fig. 5, is driven through a shaft 46 by means of gear 29, and gears 47 drive the shaft 48 to which is attached cam 49 and gear 50 which drives cam 53 working in frame 51 through gears 55.. Cams 49, 53 cause the claw 56 to feed the film. The registry device comprises a pin fitting the film perforations horizontally and vertically and a pin fitting the film perforations vertically only, the pins being attached to rods connected by a yoke 68 reciprocated by an eccentric pin 69 on shaft 46. The pressure plate 71 mounted on tube 72 and controlled by cam 73 on shaft 46 is forced by spring 74 against the film. A cam 77 operated by handle 78x withdraws the pressure plate 71 for threading. Between the flanges of the mechanism and the camera base, and between the stop and the side of the flange, are shims against which the mechanism is forced by springs. The position of the mechanism is checked by micrometers. The position of the mirrors is also adjusted by shims and checked by micrometers.

Filed: 1919-12-03
Abstract: 155,107. Oliver, A. H., and Dunbabin, J. O. Dec. 3, 1919. Theatrical appliances.-Relates to apparatus for controlling the curtains, and at the same time, if desired, the lights of cinematographs and theatres. The apparatus consists of opening and closing apparatus of the type which is operated by an electric motor and is provided with reversing means. In the present invention, in place of using a reversing-switch for the motor, the curtains are operated through a shaft fitted with reversing-gear so that the motor always runs in the same direction. The curtains are suspended from a rod 19, Fig. 13, and their forward edges are connected to carriages 21, 22 sliding on the rod 19 and a parallel rod 20. The carriages 21, 22 are fixed to the opposite runs of a rope 26 passing round pulleys 30, 31, 32 and thence to a driving-drum. The carriage 22 when it reaches its extreme central position actuates a switch on a centre bracket 28 and when it reaches its extreme outer position a switch 34. These switches are normally closed, but are opened by the carriage so as to cut off the current from an electric motor which actuates the driving-drum round which cord 26 passes. The driving-drum 12, Fig. 2, is mounted on a shaft 1 carrying loose pulleys 9, 10 which are driven from a countershaft 2 through open and crossed bands 13, 14 respectively. The shaft 2 is driven through belts 4, 6 &c. by the electric motor either of the pulleys 9, 10 can be locked to the shaft 1 by a clutch 11 actuated by a rocking lever 15 which is moved in one or the other direction by energizing one of the electromagnets 16, 17, but is normally held in the " off " position by springs 18. Two magnetic switches are provided so that either of the electro-magnets can be energized to close or open the curtains, respectively, but in both cases the current passes through the motor in the same direction. The motor can be cut-out by a switch to retain the curtains partially open. The switches may be arranged in other positions, and may be operated by stops carried by the cords.

Filed: 1969-06-16
Abstract: 1277931 Folding apparatus R FUNK & CO Inc 16 June 1969 [18 June 1968] 30287/69 Heading B8R A folding apparatus is constructed to fold sheets of differing sizes into "packets" of the same predetermined length and width. The apparatus comprises a registering feedtable 16, Fig. 1, a buckle folding unit having folding pockets 20 and 21, a first conveyer 25 for transporting folded sheets from the buckle folding unit to a receptacle 26 or for positioning the folded sheets beneath cross-folding units 27 and 28, Fig. 10. Beneath the cross-folding unit 27 is a conveyer 33 for delivering sheets to a receptacle 34. Beneath the cross-folding unit 28 is a further cross-folding unit 29, Figs. 5e and 10. Unit 29 connects with conveyer 33 via guide-plate 80. Pocket 20 of the buckle folder carries longitudinally adjustable end stop 56 and two stops 54 and 56 (carried on rotary members 53 and 55) which may be positioned to provide end stops further along the pocket when required. Each of the cross-folding units (e.g. unit 28) comprises a reciprocable blade 611 co-operating with a pair of nip rollers 31, 31. A stop 73 is provided on folding unit 29 to arrest a sheet issuing from unit 28 such that the sheet may be further folded between rollers 32, 32 by blade 76. Conveyer 25 is associated with a stop 51 which either permits a sheet to pass from the buckle folding unit into receiver 26 or halts a sheet beneath the cross-folder. Deflector fingers 50 on the buckle folding unit prevent sheets from entering the upper pocket 21 when required. Operation.-A control circuit permits a sheet registerd on table 16 to be provided with one or two first transverse folds in the buckle folding unit, the position of these folds being determined by which of the stops 54, 56, 57 is operative. The sheet thus folded is either, passed directly to receptacle 26 (stop 51 inactive) or, subjected to one or two cross folds (stop 51 active) being finally delivered to receptacle 34. For a single cross-fold unit 27 is rendered operative and for two cross-folds both units 28 and 29 are rendered operative. If a sheet does not fold exactly into a required dimension the surplus area 81, Fig. 6, may be "tucked" into the folded packet by latching blade 76 in the position shown in Fig. 6 to guide the surplus area into the nip of rollers 32.

Abstract: 926,855. Bundling machines. METAVERPA N.V. Sept. 5, 1960 [Sept. 5, 1959], No. 30487/60. Class 94(1). In a package binding machine of the type having a fixed wire guide track, the wire end clamp is moveable in and opposite to the entry direction of the wire end and also at right angles to such movement. Clamping is achieved by a disc 15 pivoted at 16 and raised and lowered by piston and cylinder means 21 and links 18-20. The clamp is mounted on a rod 11 held in a groove in a fixed member 13 by a leaf spring 12. As the wire enters the open clamp, Fig. 5, it displaces the latter against the spring 12, to operate a switch 22. The means 21 is thus activated to move the rod 19 to the left, Fig. 2, to close the clamp, and the wire is then taken up. Taking up the wire pulls the clamp to the left, Fig. 5, and repositions the switch 22 to initiate tensioning, wire tying and final severing. When the wire is severed, the clamp returns to a neutral position relative to the switch, causing the means 21 to thrust the clamp to the right, Fig. 2, after opening it so that the wire end may drop clear. The guide may include wire retaining means 2, 3, 5 as described in Specification 922,759.

Title: An improved manufacture of ethers from olefins
IPC: C07C41/01
Filed: 1939-11-22
Abstract: 535,111. Ethers. STANDARD ALCOHOL CO. Nov. 22, 1939, No. 30580. Convention date, Dec. 31, 1938. Drawings to Specification. [Class 2 (iii)] Ethers are made from olefines by a process of the kind described in Specification 403,654, in which the olefine is absorbed in an acid catalytic liquor such as sulphuric acid at raised temperature and pressure, ether being removed from the liquor by distillation at reduced pressure. According to the invention the ether is removed at a reduced (preferably substantially atmospheric) pressure and at substantially the same temperature as that at which the absorption is effected, the ether being then separated from the accompanying small proportion of alcohol and the alcohol is returned to the partially stripped liquor which, after the necessary addition of water, is returned for further use. The absorption liquor may be sulphuric acid of less than 84 per cent. strength, preferably 50-70 per cent. The olefine employed may be pure or dilute, the process being described with reference to two diagrammatic drawings, one for each case. In an example, propylene is absorbed in sulphuric acid of 60 per cent. at 100‹C. and 190 lb. pressure, the ether being removed at 95-100‹C. and atmospheric pressure so as to give a " flash " distillation. The small quantity of isopropyl alcohol separated from the isopropyl ether is returned. to the partially stripped liquor, to which is also added the quantity of water equivalent to that which has been reacted.

Title: Process for the deoxidation of ferrous metals with cyclic utilisation and regeneration of slags
IPC: C21C7/00
Filed: 1934-10-25
Abstract: To extract oxides from ferrous metals, e.g. steel, acid slags are used in which the ratio of the manganese oxide content to the iron oxide content is equal to or greater than 4, the content of manganese oxide being preferably greater than 5 per cent. Periodic regeneration of the slag is effected to restore or maintain the value of the manganese oxide-iron oxide ratio.  The slag may be melted and intermixed violently with the metal or may be used in the solid state in a ladle.  The manganese oxide content may be so high, e.g. up to 30 per cent, that manganese is introduced into the metal, and the metal may also be enriched in silicon by reduction of silica in the slag.  The iron oxide content of the slag is low, e.g. less than 4 per cent.  The regeneration of the slag is effected by reduction of iron oxide by means of a reducing agent followed by replacement of part of the slag by fresh materials to compensate for any increase in the manganese oxide content and to restore the initial composition as regards silica and any basic materials, e.g. calcium oxide.  If the metal has been enriched in manganese, manganese oxide must be added to the slag during regeneration.

Filed: 1962-08-10
Abstract: 955,918. Pilot controlled A.V.C. A. DERACINOIS, and H. F. G. LASSAIGNE. Aug. 10, 1962 [Nov. 14, 1961], No. 30702/62. Heading H4R. In a pilot controlled A.V.C. circuit for a carrier telephone system the variable impedance control network includes a transformer and two resistance arms at least one of which arms includes an indirectly heated thermistor the heater current of which is controlled by the rectified pilot signal. Five alternative control networks are described, all derived from a conventional lattice network. Fig. 5 shows the control system in which a variable impedance network 10 and repeater amplifier 20 are included in a communication line labelled 1 at the input, 2 at the output. The impedance of network 10 is controlled, via the thermistor resistor 11, by the thermistor heater current which is derived from the pilot signal in control circuit 50. The pilot signal after passing filter 30 and amplifier 40 is rectified by rectifier 51 and compared with a reference signal, derived from Zener diode 506, in transistor 503. The error signal controls transistor 507 supplying the thermistor heater current to vary the loss in network 10 and so tends to maintain the pilot signal at a constant level. The thermistor is connected together with resistors 601, 602 and 603 in a bridge network fed with a constant potential developed across Zener diode 514, and the unbalance voltage of the bridge is applied to a galvanometer relay 604 to indicate the change in attenuation of network 10 and to operate alarm circuits should the change be excessive. In addition failure of the pilot signal is detected by transistor 701, which is fed on its base with the rectified pilot signal, and operates alarm relay 702. Alternative forms of variable impedance network. Fig. 6 shows a network 10 utilizing shunt and series thermistors the heater currents of which are differentially controlled by connecting the heaters in a bridge network one diagonal of which is fed with the control current derived from the pilot signal while the other diagonal is fed with a reference current from source 110; variations of the control current then differentially alter the two thermistor heater currents and by suitably choosing both the reference source and the thermistors the characteristic impedance of the network 10 may be maintained within close limits over the operating range of control. Figs. 7 to 9 illustrate other forms of control network differing only in detail from the network 10 shown in Fig. 5.
