Title: Friction clutch particularly for controlling a motor bicycle
IPC: F16D43/18
Filed: 1959-06-11
Abstract: 884,609. Friction clutches. OFFICINE MECCANICHE F. LLI DALDI & MATTEUCCI S.p.A. June 11, 1959 [Oct. 13, 1958], No. 20066/59. Class 80 (2). [Also in Group XXXI] A friction clutch comprises radially movable elastically deformable elements such as rubber, &c. rollers so mounted upon one clutch member that when they are initially brought into frictional engagement with a co-operating clutch member for torque transmission, they are constrained to perform a substantially rolling movement, increase of the clutch-engaging force constraining the rollers &c. to slide, rather than roll, upon the co-operating clutch member. The clutch may be centrifugally, hydraulically, pneumatically or mechanically controlled. In the form shown, two oppositely directed centrifugally engaged clutches according to the invention are mounted upon the engine crankshaft 2, Fig. 1, of a power-assisted pedal bicycle, one clutch transmitting engine torque to the rear road wheel of the bicycle, and the other transmitting torque from the rear road wheel to the crank-shaft when the bicycle is pedalled to start the engine. The main clutch comprises a disc 8 secured to the crank-shaft 2 and carrying on pivot pins 12, 13, Fig. 2, masses 10, 11 which move radially outwards against the bias of springs 30 with increasing engine speed so that resilient rollers 32, 33 therein engage the inner periphery of a ring integral with a pulley 1 journalled upon the crank-shaft. The rollers 32, 33 may be made from rubber or synthetic material, and may be of cylindrical, barrel, conical or other shape. On initial engagement, the rollers 32, 33 tend to roll on the cylindrical surface of the pulley 1, increasing clutchengaging force with increasing engine speed forcing them down into their sockets in the masses 10, 11 so that they are held from rotation, and instead slide over the driven cylindrical surface until such time as clutch engagement is completed. The starting clutch comprises masses 4, 5, Fig. 3, pivoting about pins 6, 7 in the pulley 1, pedalling the bicycle driving the pulley so that the masses move radially outwards against the bias of springs 22 to engage pairs of resilient rollers 24, 25; 26, 27 with the inner periphery of a cup-shaped hub 28, keyed to the crankshaft 2, around which they first roll and then slide.

Title: An interlocking device for two movable parts in a machine, for example, a machine having a radiation gauge
IPC: A24C5/34
Filed: 1955-07-12
Abstract: 822,354. Cigarette-making machines. WILLIAMS, H., and MOLINS MACHINE CO. Ltd. July 9, 1956 [July 12, 1955], No. 20131/55. Class 130. [Also in Groups XX and XXV] In a machine in which two parts are movable in a given direction, each part carries a recessed rod engageable with a catch and each rod has an unrecessed portion which slidably engages the catch to prevent it from engaging the recess in the other rod so that only one rod and its associated part may be moved out of range of the catch. Preferably, the parts carry a radioactive source and a ray-responsive device and the interlock prevents either of the parts from being moved to a position in which the source is unshielded. As shown, the device and source are a radiation gauge in a continuous rod cigarette - making machine. A stream of tobacco is carried on a moving paper web 1 between fixed guides 2 and the mass flow of the stream is measured by a #-ray source in box 3 and an ionization chamber contained in casing 4. The #-ray source is shielded when the carrier 6 of casing 4 is in position or when carrier 5 of box 3 is moved to a position adjacent a stationary part of the machine. Carriers 5 and 6 have bolts 14 and 15 attached thereto. When both carriers are in the source-shielded position either can be moved, the latches 16, 17 (not shown) being retained on the thickened stem portion of one bolt 14 or 15, thus allowing the recessed head portion of the other bolt 15 or 14 to be withdrawn therebetween. Attempted withdrawal of the remaining bolt, which would expose the #-ray source, brings about engagement between the latches and the recessed head of the bolt. Reflecting prism 19, carried on the stationary part of the machine, allows inspection of the source in the shielded position of carrier 5.

Title: Improvements in or relating to electrical delay circuits
IPC: H03H7/30
Filed: 1955-10-10
Abstract: 771,372. Applying rupturing voltage to several fused circuits successively; condenser arrangements. MICROCELL, Ltd., TRAVERS, R. S., and KREMER, H. Oct. 10, 1955 [July 9, 1954], No. 20223/54. Class 38 (4). Sequential rupturing of a number of rocketfiring fuses F1, F2 ... , connected across a common supply source, is controlled by condensers C1, C2 ... , individually associated with the separate fused circuits and having as dielectric material barium, or strontium titanate, or the like, of which the dielectric constant varies with temperature. In the arrangement shown, each fuse circuit, other than the first, includes, in series, the condenser controlling that circuit and a heating coil HC<SP>1</SP>, HC<SP>2</SP> ... , for the condenser associated with the next circuit. The passage of rupturing current through one circuit thus energizes the heating coil associated with the condenser of the next circuit allowing current to build up to rupturing value in that circuit and energizing the heating coil for the circuit. The condensers are thus heated in succession and the fuses blown sequentially. In modified arrangements the fuses may be controlled through trigger circuits from the condenser circuits; the condensers may be directly heated by heat generated by a preceding rocket; or the condensers may all be heated simultaneously, but arranged so as to have different time delays such as will result in the sequential blowing of the fuses.

Title: Improvements in devices for protecting metal-drawing presses
IPC: B21D55/00
Filed: 1939-07-14
Abstract: 531,213. Machinery guards. OPEL AKT.-GES., A. July 14, 1939, No. 20525. Convention date, Aug. 12, 1938. [Class 80 (iv)] Stamping presses are provided with a safety device to prevent injury to the dies in the event of the metal fracturing during the operation in which case compressed air escaping through the crack lowers the pressure in the supply pipe and movement of a spring-loaded piston causes the operation of a visible or audible signal and may stop the press. The escaping air may actuate a siren. In the form shown the metal is most likely to crack at 6 and air is fed to this part of the punch by conduits 7 fed from a distribution channel 10, supplied at 8 with compressed air through a valve 9. A branch port 19 supplies a cylinder with a spring-loaded piston. Whenever air escapes at 7 the resulting drop of pressure enables the spring 16 to close switch 15, and if this occurs during the drawing stroke the drop B, C in a cam 23 rotating synchronously with the press shaft has also enabled a switch 22 to release and a signalling device such as a lamp 11 is actuated. The high part A of the cam opens the switch 22 and prevents the signal from being actuated during the up-stroke of the press on the down-stroke before the draw is sufficiently advanced to close the conduits 7. The switches are double acting and in the positions in which the signal circuit is broken they close the circuit through a solenoid 26 that maintains a switch 28 closed. The two solenoid switches are in parallel and consequently the switch 28 is maintained closed except when the alarm signal 11 operates. The press then stops and can be packed to remove the defective work before damage occurs to the dies.
