Title: Injector device
IPC: B21D53/02
Filed: 1956-05-15
Abstract: 815,492. Making heat exchangers; stamping. IMPERIAL CHEMICAL INDUSTRIES Ltd., and BURTON, J. S. May 1, 1957 [May 15, 1956], No. 15122/56. Classes 83 (2) and 83 (4). An injector device for use in the manufacture of sheet metal panels with internal passages for use as evaporators in refrigerators comprises a hollow body member 13 adapted to be connected to a source of hydraulic pressure, a liquid supply nozzle mounted in a holder 11 for movement between its operative and retracted positions, gripping means for gripping an article into which liquid is to be injected, resilient sealing means mounted on the nozzle and adapted to seal an aperture in said article into which the nozzle is inserted, said nozzle holder having a forwardly directed projecting portion surrounding the nozzle and spaced therefrom to define a leakage space, said projecting portion having a forward abutment face of substantially smaller area than the crosssection of the sealing means and adapted to engage the sealing means in liquid-tight manner when the nozzle is in the operative position. The nozzle consists of a needle 10 and a rubber hydraulic seal 16 surrounds the end of the needle. Annular spaces 34, 35 are formed in a recess in the needle holder by an annular projection 33 (Fig. 3). The body member 13 is in screw-thread engagement with a flanged nut 18 secured in a holder 19 attached to a grip support member 21 having spring steel grips 26. The nut is rotated by a key 22 to advance or retract the needle holder 13. The grips 26, actuated by platens 30, have shoulders for engaging the sides of platens between which sheets 31 are located during the inflating operation, the platens limiting the degree of inflation. Auxiliary gripping mechanism comprises upper and lower jaws 40, 41 for bearing on the upper and lower grips 26 respectively. The lower jaw is pinned to the lower end of links 46, 47 (Fig. 4). The upper jaw has slotted extensions 48, 49 through which extend the circular cams 50, 51 of a roller 52. The cams 50, 51 are concentric with the roller but they lead to eccentric cams 53, 54 at their outer ends which engage in slots in the upper ends of links 46, 47. The jaws also have rearwardly extensions loosely pinned to vertical support members 57, 58 secured to the nut holder 19 of the device. The mechanism is operated by a lever 61 fixed to the roller which causes the jaws to close on the grips and assists them to bite into the sheets held between them.

Title: Improvements in and relating to electrical signalling systems and means for use with microphonic apparatus
IPC: H04R27/00
Filed: 1929-05-16
Abstract: 333,310. Graham Amplion, Ltd., and Phillips, C. F. May 16, 1929. Public address systems; systems modified for using condenser telephones. - The user of a microphone, for example in a public address system, is informed by a lamp, indicator or other visual signal and, if desired, by an audible signal, when the microphone is connected at a more or less distant control point to the transmitting circuit. When the microphone circuit is switched in at the control point, a slow-tooperate thermostatic relay associated with the microphone completes the microphone circuit after disconnecting the audible signal. When the control switch 4a, 4b, Fig. 1, is operated to connect leads 5, 6 from the transmitting circuit to the carbon microphone 1, the signal lamp 2, buzzer 12 and thermostatic relay 13 are operated in series in parallel over lead 6 and a common and preferably grounded lead 7 connected to one pole of source 9. When relay 13 operates the bi-metallic element 10, the circuit of buzzer 12 is opened and the microphone circuit is completed over leads 5, 7. When a magnetophone is used, the transformer 8 is omitted and lead 5 from the winding of the magnetophone is connected either over a biassing battery to the grid of valve 3, or over a blocking condenser to the grid, bias being connected to the grid through a resistance. When a condenser microphone Ic, Fig. 4, is used, the local microphone circuit is completed over 19, 20, 21, 14 when the thermostatic relay 13 operates. The local and central amplifier system described in Specifica. tion 333,312 may be used, the local amplifier being indicated at x, Fig. 4.

Title: Improvements relating to photographic roll film cameras
Inventor: CORFIELD KENNETH GEORGE
IPC: G03B19/04
Filed: 1957-05-15
Abstract: 834,941. Photographic roll film cameras CORFIELD Ltd., K. G. May 7, 1958 [May 15, 1957], No. 15387/57. Class 98(1) In a roll film camera having a film winder and a counter comprising a dial or pointer mounted on a shaft driven through a friction clutch from the winder, the dial or pointer co-operates with a pointer or scale secured to or keyed to the shaft and is held still during a small fixed part of the rotation of the shaft to alter the counter indication by engagement of a detent mounted on a stationary part of the camera under the control of a cam surface on a part rotating with the shaft. As shown, the film wind knob 2 on the shaft 3 driving the take-up spool is connected through a friction clutch comprising a spring 10 with a counter dial 7, a co-operating mark being provided on the knob 2 which is attached by screws to the flange 17 on the shaft 3. Formed on the lower face of the dial 7 is a toothed ratchet wheel 14 visible through opposed apertures 16 in a housing consisting of a hollow spigot 15 formed on the underside of the knob. During the 180 degrees rotation of the knob required to wind the film one frame, a pivoted pawl 24 fixed to the camera arrests the ratchet wheel 14 under the control of a cam surface 27 in the lower margin of the aperture 16 which engages a stud 26 on the pawl and thus briefly arrests the dial 7 relatively to the knob, so counting an exposure. Feeding of the film also winds the shutter through gears 4, 5, 6, a peg 20 on the flange 17 normally engaging in one of the castellations 21 on the gear 4. To permit winding of the film without setting the shutter, as when reinserting an unfinished reel, the peg and castellations may be disengaged by operation of a plunger which moves the gear 4 downwardly. The Provisional Specification refers to' a construction in which the film winding knob is turned one complete revolution to feed one film frame so that only one aperture is provided in the ratchet wheel housing.

Abstract: 476,309. Float-actuated valves. MULLER, J. June 3, 1936, No. 15550. Convention date, Aug. 30, 1935. [Class 135] [Also in Group XVII] A means for stopping the filling of tanks when a. predetermined and adjustable level has been reached, comprises in the form shown in Fig. 1, a float 4 on an arm 5 pivoted at 6 and carrying a pointer 7 which, when the float rises, contacts a pin 11 which can be placed in any one of a number of holes 10 in a pivoted sector 9 which, through an arm 12 actuates a valve 2 to close the inlet. In the form shown in Fig. 2, a float 4 secured at 13 to an endless chain 12 moves freely upwards as the tank fills until a stop 17 on the shaft 16 of a pulley 15 actuated by the chain contacts a stop 18, when the free movement of the float being thus inhibited, a further rise in the level of the liquid causes the float to lift rod 3 and close inlet valve 2. Adjustment is effected by moving pulley 15 with respect to the chain. In the form shown in Fig. 3, a cylinder 21 is held in the position shown by an adjustable weight 26 through a system of levers 22, 23, 24, movement taking place about a pivot 25. When the upthrust on the cylinder reaches a predetermined value, the cylinder rises and closes the inlet valve 2.

Abstract: 1476762 Phase-changing transformers FERRANTI Ltd 9 April 1975 [9 April 1974] 15571/74 Heading H2F A transformer for use as either element of a Scott-connected pair of transformers has its primary winding formed by two pairs of coils, the two coils of either pair having the same number of turns whist the number of turns of the coils of the two pairs are in the ratio 1 : (2-#3). Fig. 1 (not shown) relates to a pair of Scott-connected transformers connected to a synchro so as to provide sin and cos components. Fig. 5 shows one of the transformers, winding X having the same number of turns as X<SP>1</SP> and similarly Y = Y<SP>1</SP>. For use as the cosine transformer in a Scott pair, link 41<SP>1</SP> is provided and terminals 3 and 5 form the effective primary connections. For use as the sine transformer, link 41<SP>1</SP> is replaced by a link 42 and terminals 1, 3 and 6 provide the primary connection. The use of primary windings connected in opposition enables the resistance of all three arms to be the same whilst maintaining the desired voltage ratios. Bifilar windings may be used.
