Title: Improvements relating to folding cameras
IPC: G03B17/52
Filed: 1970-05-11
Abstract: 1,248,877. Folding cameras. POLAROID CORP. May 11, 1970 [May 13, 1969], No.22594/70. Heading G2A. In a folding camera having a support member 28 which can be moved from a closed position to an open position for insertion of a photo-sensitive element, a locking means 50 which enables member 28 to be opened for said insertion can be so actuated only when the camera is in the unfolded position. As shown in Fig.1 in the unfolded position, the camera-comprises a housing section 18 which includes the objective lens 44, shutter, and various controls, and is pivoted to member 28 by pins 42. Section 18 is hinged to an adjoining section 20 which when the camera is closed forms a front cover Fig.2 (not shown). Erecting links 40 are pivoted at one end to member 28, as at 90, and at the other end to a section 38 containing the finder. The lower or back section 12 of the camera has a door 24 hinged to member 28 at 30, so that it can be swung away from the housing as in Fig.1 to permit loading or unloading of a film pack 53. Lying within a recessed portion of door 24, and pivoted to it at 126, is a locking arrangement 100, seen in more detail in Fig. 5 (not shown), comprising two linked levers (113, 128). At each end of the lever arrangement are upturned lugs 114, 130 having respective recesses 116, 132. When the camera is folded up, pins 94 on member 28 engage and lock into these recesses under spring action, so that door 24 is locked closed. It is unlocked, when required for insertion or removal of a photo-sensitive element, by actuating a release 108, which pivots the lugs out of locking engagement with pins 94 and allows door 24 to be opened. When the camera is completely folded up, as in Fig.2, the release 108 is wholly enclosed and therefore not accessible. Thus a film pack cannot be inserted when the camera is folded up, so avoiding any risk of scratching the reflector 16. Only when the camera has been unfolded into the erect position of Fig.1, and the reflector 16 is spaced from member 28, can the release 108 be actuated to open door 24.

Title: Improvements relating to push-button electric circiut breakers
IPC: H01H37/48
Filed: 1946-08-02
Abstract: 615,187. Automatic circuit-breakers. SABATINI, U., and CIAMPOLINI, V. Aug. 2, 1946, No. 23079. Convention date, Jan. 18. [Class 38 (v)] A push button circuit breaker with manual, thermal and electromagnetic tripping, has a moving element B carrying moving contacts 2 and a coil S connected and fixed between the contacts. A second moving element A has a T-shaped slot in which three balls may move. When the circuit breaker is closed, Fig. 4, the two elements are locked together by these balls and if a heavy overload occurs the coil S attracts an armature 6 which pulls down a striker 7 to displace the centre ball so allowing the outer balls to move in to release the contact carrying element B under the pressure of springs 9, to open the contacts 2, 3, Fig. 2. A bimetallic strip, Figs. 5, 5<1> (not shown), supported on the armature 6 can move the striker to open the circuit breaker, when heated by the coil S under sustained overload conditions. .The switch is tripped manually by depressing the button D which also moves the striker 7. To reset the circuit breaker, the button is depressed fully which moves element A down and compresses the springs 1, 9 and 11. The downward movement of the striker 7 ceases when it again touches the central ball now supported on a spring 12 and the spring loaded - pads 8 carried by the push button grip the striker as it slides between them. On releasing the push button the balls, which are now in line, relock the two elements A, B so that the springs 1 force the locked assembly up to reclose the contacts 2, 3. The striker is carried up by the push button and released from it near the end of its travel by the armature, so as to be ready for any further tripping. A multipole circuit breaker is formed by coupling together a number of the switches shown in Fig. 4, so that the limbs 10 of H- section members in effect, couple together adjacent armatures 6 and elements' B. Figs. 5, 51, 6, 61, 7 and 71 (not shown) illustrate various methods of mounting the bimetallic strips or discs on the armature, and Figs. 8, 81, 9, 10, 11, 111, 12 and 12<1> (not shown) illustrate alternative methods of mounting spring members which take the place of the pads 8.

Title: Improvements in pneumatic tube conveyors
IPC: B65G51/30
Filed: 1937-08-27
Abstract: 478,807. Pneumatic despatch apparatus. TELEPHON - APPARAT - FABRIK E. ZWIETUSCH & CO., GES. Aug. 27, 1937, No. 23543. Convention date, Dec. 24, 1936. [Class 78 (i)] The receiver 9 of an intermediate station of a pneumatic tube conveyer is connected to a junction box 4 by two pipes 7, 8. The main conveyer tube 1 is interrupted in the junction box and the two portions are normally connected together by a switch tube 10 pivoted at 11 to the incoming tube and connected thereto by an air-tight connection 13. A spring-pressed slidable sleeve 12 mounted on the outgoing tube fits over the other end of the switch tube, and a corresponding sleeve is mounted on the end of the pipe 7 within the junction box. When a carrier is to be discharged from thereceiver 9, the operator completes a circuit to a solenoid 15, energization of which retracts the two sleeves 12 through the linkage shown and holds them retracted against the springs 16. As the sleeve on the tube 1 arrives in its retracted position, it completes a circuit to another solenoid 14 which causes the switch tube 10 to be rotated counterclockwise against a spring 17 to a position in which it is in alignment with the pipe 7. When in this position the switch tube breaks the circuit to the solenoid 15 and the sleeves 12 are pushed forward by their springs 16 so that the switch tube is now connected to the pipe 7. Forward movement of the sleeve 12 on the outgoing tube 1 breaks the circuit to the solenoid 14, but the switch tube remains connected to the pipe 7 through the sleeve 12 thereon. The arrival of the carrier in the receiver 9 again completes a circuit to the solenoid 15 to retract the sleeves 12 again, whereupon the switch tube 10 is restored by its spring 17 to its normal position, the retraction of the sleeves on this second occasion not energizing the solenoid 14 as the circuit thereto is broken by the movement of the carrier, the carrier finally breaks the circuit to the solenoid 15 so that the sleeves 12 are now restored by their springs and the main conveyer tube 1 recompleted. The carrier now rests in the receiver on a pivoted flap 21 biassed upwardly by a spring 20. A pressure relief valve 34 in the junction box equalizes the air-pressure on both sides of the flap which is now depressed by the weight of the carrier against the spring 20 and so releases the carrier.
