Filed: 1943-02-15
Abstract: 559,835. Sound film drive mechanism. RADIO CORPORATION OF AMERICA. Feb. 15, 1943, No. 2472. Convention date, Feb. 13, 1942. [Class 40 (ii)] Relates to machines for recording or reproducing sound on or from a film passing over a sprocket 12 and a drum 13, both of them driven to drive the film, the drum 13 being associated with a fly-wheel 22 and driven through an aperiodic yieldable coupling such as a magnetic clutch 24, 35. According to the invention, the driving mechanism is arranged to speed the sprocket 12 more quickly than the drum 13 when starting. In one arrangement, Fig. 1, the drive from a primary shaft 14 is positively transmitted to the member 24 of the magnetic clutch through gearing 18, 21 ; and the drive from the same primary shaft 14 is transmitted to the sprocket 12 through a torque limiting clutch 15, 36, the member 15 co-operating with the flanges of a split ring 31, Fig. 2, expanded by a spring 32 to grip the surrounding clutch member 36 in known manner. The clutch member 36 is fast with a fly-wheel 30 and a gear wheel 16 in mesh with a gear wheel 28 on the shaft of the sprocket 12. In a modification, Fig. 3, the sprocket 12 and the drum 13 are driven by separate motors 40, 50. The motor 40 is a polyphase motor driving the sprocket 12 positively when supplied from a motor generator 44, 42, having a torque-limiting clutch 49 and a fly-wheel 47 between the motor and the generator. The motor 50 drives the drum 13 with a fly-wheel 22 through a magnetic clutch 24, 35 as in the arrangement of Fig. 1. The motors 50 and 44 are supplied from a common source 46 and started simultaneously by a common switch 45. The speeding up of the motor 44 is controlled by a starter device 48, and the slip clutch 49 still further controls the speeding- up of the generator 42. This arrangement permits several separate films to be started simultaneously in synchronism. the several motors 50 being all connected to the same source 46 through the same switch 45, and the several motors 40 being all supplied from the same generator 42.

Patent GB-832654-A (GB)
Title: Method and apparatus for washing and extracting fluid from clothes or fabric articles
IPC: D06F43/02
Filed: 1958-01-27
Abstract: 832,654. Washing-machines; wringers. INTERNATIONAL LAUNDRY MACHINERY CO. Jan. 27, 1958, No. 2608/58. Class 138 (2). In a machine for washing and extracting fluid from clothes or fabric articles, the articles are tumbled in a drum having a closed access opening at one end while they are simultaneously mechanically compacted into a confined space of substantially reduced volume at that end to remove a substantial portion of the fluid therefrom, a fluidpressurized diaphragm is then expanded against the articles to further compact them at substantially higher pressure to extract additional fluid therefrom, and finally the access opening is opened and the articles forcibly ejected from the drum, preferably by means of the mechanical compacting force. The volume of the confined space may be substantially increased whilst tumbling the articles to relatively loose fluffy condition. In the form shown, a horizontal rotary drum 12 is sealed at 16 to a fixed end 14 and is attached by vanes 25 to a cylindrical hub 24 which is slip-sealed at 26 in the end 14 and is supported by rear rollers 21 carried by an upright 23. A closure 34 for the front access opening is rotatably mounted by a bearing 35 on a support 36 which is rotatable about a vertical axis 39 (not shown), the closure 34 being lockable to the drum by means of radially separable semicircular locking members 43. The end 14 carries a water outlet 58 controlled by a valve 57 which is operated by a fluid-pressure cylinder 59, and the drum is fitted with perforated hollow clothes-agitating ribs 62. A non-rotatable perforated water-extracting plunger 65 is reciprocated within the drum by means of a fluid-containing cylinder 68 slidable within the hub 24 and over a piston 69 connected to a fixed sleeve 70 carried by a bracket 72, pressure fluid being supplied by conduits 75, 76. The plunger 65 is held in its forward position by means of pins 77 passed through bushes on the plunger and moved by a fluid-pressure-operated T-ring 83 (not shown). The additional compacting is effected by a diaphragm 108 operated by pressure-fluid supplied by a conduit 110, and pinching of the clothes between the periphery of the diaphragm and adjacent portions of the drum is prevented by an annular flexible flapper 114 secured to an annular ring carried by peripherally-spaced rods 117 acting against compression springs 120. In a modification the diaphragm 108 forms part of a readily removable self-contained unit.

Title: Improvements in motion-recording and like apparatus of the travelling strip type
IPC: G01P1/12
Filed: 1922-01-28
Abstract: 174,639. Desenne, G. Jan. 29, 1921, [Convention date]. Recording-apparatus.-A pencil reciprocated from the vehicle-wheel, or by the machinery the movements of which are to be recorded, marks upon a clock-driven strip or disc. The apparatus is stated also to be applicable for use in the supervision of factories &c. at night. Roller-and-sheet apparatus.-The instrument shown in Figs. 3 and 4 consists of an upper section enclosing the pencil-operating mechanism, and two lower sections containing respectively the clockwork and the recording parts. The pencil 24 preferably of silver is removably mounted in a holder screwed to a shaped slide 12 supported by a similarly shaped frame 21 and attached to a rod 11 spring-pressed against a cam 9 on a shaft 4 rotated by driving-connection with the vehiclewheel. The pencil is thus moved to-and-fro across the strip at each kilometer travelled. The strip passes from a supply roll 29 to a driven winding- on roll 33 across a roll 31 also driven by the clockwork and provided with pins to engage holes in the margin of the strip, which is kept pressed down by a roller 35. In order to interrupt the recording if the casing cover be removed, a lever 27 normally rendered ineffective by resting against an abutment on the cover, is adapted when freed to raise the pencil from the strip. The number of kilometers traversed is registered upon a counter 17 by means of a spring-controlled non- rotary ratchet sleeve 15 reciprocated upon the shaft 4 by means of a similar sleeve 14 fixed to the shaft. The actuation of the counter proceeds irrespectively of the direction of the drive, by the interposition of a double ratchet-shaped collar 16. The Specification, as open to inspection under Sect. 91 (3) (a), comprises also the following:- Disc-recording apparatus.-The record-disc 38, Figs. 10 (Cancelled) and 12 (Cancelled) mounted on a spindle 42 driven by clockwork disposed within a sleeve 37 secured to the back wall of the casing. Arranged to rotate upon this sleeve is a ring formed by the combination of a spur-wheel 45 driven by the vehicle and a cam 44 serving to reciprocate the pencil carrier 50 through the medium of a ball 48<1> and lever 48. The record surface is intended to rotate once in twelve hours and, so that it need not be changed for a further period of twelve hours, means are provided for holding off the pencil after the first rotation of the disc. To this end, a slotted spring-controlled lever 53 embraces the pencil-holder and is normally held ineffective by a T-shaped detent 60. At the end of the first rotation a pin 63 on the disc deflects the detent to release the lever 53 which then forces and holds the pencil 24 away from the record surface. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to arc extinguishing structures for electric circuit breakers
IPC: H01H9/34
Filed: 1948-01-29
Abstract: 634,490. Arc - rupturing in switches. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. Jan. 29, 1948, No. 2692. Convention date, March 13, 1947. [Class 38 (v)] A circuit -breaker. has an arc shoot containing a " deion grid " of spaced parallel plates, in which steel plates alternate with copper plates and the shoot has a set of grooves for each kind of plate, the dimensions of the plates and grooves being such that each kind of plate only fits the appropriate set of grooves. Each steel plate 30, Fig. 9, is formed with a notch 31 and has a width slightly less than that of the copper plates 36, Fig. 7. The arc shoot has two sets of grooves on the opposed side walls of the shoot 43, Fig. 4, the upper set 44 extending more deeply into the side walls than the lower set 45. Thus the copper plates 36 can only be slid into and retained by the lower grooves. To accommodate the arcing horn 12, Fig. 1, when the switch is fully open, the end steel plate 53 is formed with a recess 54. This end plate 53 and the other steel end plate 61 have hooks 60 which fit into recesses at each end of an insulating baffle 59 and retain the baffle member in position. The steel and copper plates together with the baffle are retained in the arc shoot by insulating tubes 71 which are inserted through holes in the right-hand arc shoot wall (as seen in Fig. 1), and pass through holes 38 in the copper plates and recesses 35 in the steel plates. The arc shoot is secured to the base-plate 1 of the switch by bolts 72 which pass through the tubes 71. When the circuit breaker is opened, the arc drawn between the arcing horns 7, 12, is driven up towards the apexes 34 of the notches 31, and if not extinguished before reaching the apexes, the arc 28 subdivides into a plurality of short arcs between the steel plates. The presence of the copper plates 36 between the steel plates causes further subdivision of the arcs and, due to the high heat conductivity of copper, rapid cooling. The barriers 69 of the baffle 59 are located against the tops of the steel plates to prevent the re-formation of a single arc above the plates and the baffle may be of melamine so that the gas evolved by it may prevent the restriking of the arc.

Title: An improved process for the manufacture of linoleum covering material
IPC: D06N1/00
Filed: 1925-02-03
Abstract: 242,832. Schicht, G., and Eisenstein, A. Feb. 3, 1925. Plastic compositions containing fibres, oxidized oils, &c.-In the manufacture of linoleum &c., the raw materials are mixed together in such proportions that the resulting mass is just pulverulent, the mixture is oxidized by usual methods, and the remaining ingredients are added, during or subsequent to the oxidation. The temperature may be greater than 70‹ C., but must be below that of carbonization. The heat developed by the reaction may be utilized to oxidize fresh varnish, or the temperature may be reduced by the addition of cork &c., according to the proportions in the original mixture and of the final product. Several examples are given, of which the following is typical-32 kg. of oil varnish and 8 kg. of resin are combined by heating. 30 kg. of this mixture are mixed with 40 kg. of wood meal and 20 kg. of mineral colour, and the mixture is heated to 150‹ C. in the mixer. When the reaction sets in, heating is discontinued, and 5 kg. of the varnish mixture is added. When the reaction regains its height, the remaining 5 kg. of varnish is added. Finally, 10 kg. of a mixture of varnish, resin, wood meal, and colour is added, the heat being sufficient to oxidize this last addition without appreciably raising the temperature. Specification 7242/98, [Class 91, Oils &c.], is referred to.
