Filed: 1973-06-22
Abstract: 1440232 Safety-belt winding drum KANGOL-TEKA SICHERHEITSGURT GmbH 22 June 1973 [24 June 1972] 29741/73 Heading A3V [Also in Division F2] A winding drum for a vehicle safety belt 21 comprises a hub 22 through which passes a spindle 24 which is normally free to rotate with the hub to allow free unwinding of the belt but which can be locked against rotation in the event of abnormal acceleration by a locking device 20 whereupon rotation of the hub takes place against the action of braking means to absorb the energy of a belt wearer, means being provided to limit the relative rotation between hub and spindle. In a first embodiment of the braking means balls held in axial channels in the spindle are arranged to be guided along helical tracks in the hub with plastic deformation of the tracks. In a second embodiment a nut is keyed to the hub and screw-threadedly engages the spindle, noses on the nut and co-operating channels in the hub increasing in their radial dimension towards the left hand end so as to cause plastic deformation of the channels as the nut is displaced to the right. In a third embodiment shown in Fig. 8 a plunger 50 between the spindle and hub defines a chamber 56 at the right hand end of the drum which contains a plastically deformable mass or high viscosity liquid and the plunger is provided with flow-restricting openings 58. When the spindle is locked and the belt pulled with a predetermined force a shear pin 52 gives and the plunger is displaced axially to the right, guided by a tongue and groove joint 54, with consequent energy absorption by the forced flow of the mass or liquid through the opening 58. In the fourth embodiment shown in Fig. 9 friction linings 74, 74' are pressed with adjustable bias by a set of dished washers 86 against brake linings 80, the friction linings being rotationally fast with the spindle 24 and the brake linings being rotationally fast, through the intermediary of a brake disc 82, with the hub 22.

Abstract: 324,091. Graseby, R. C. Oct. 15, 1928. Guillotine machines; pivoted-blade machines.-In a machine for cutting photographic films and for other purposes, one of a pair of spring-connected movable members is moved to stress the spring, and the knife is connected to the other member, which is held during the stressing and is afterwards released to effect the cutting. A spindle 4 rotated from a motor drives a spring drum 5 to stress a spring 6 secured to a member 7 carrying a cam 9 engaging a stop 10. As the spindle rotates, a pin 16 on the spindle engages a pin 15 on a stop 11 and carries it round against the urge of a spring 20 until the stops 10, 11, which are geared together, reach a position in which the cam 9 slips past the stop 10. The stop 11 is rotated to obstruct the cam. The pin 16 then moves past the pin 15 and the stops are turned backwards by the spring 20 to release the cam 9, and the spring 6 then operates the member 7 rapidly. The cam 8 engages a roller 25<a> on a lever 24 actuating the knife 28 to sever the strip 37. The member 7 continues to move until the cam 9 again engages and is held by the stop 10. After the cam 8 has passed the roller 25a the spring 36 moves the cutter to the inoperative position. Specification 324,096, [Class 98 (i), Photographic cameras &c.], is referred to.

Title: Improvements in or relating to operating mechanism for electric switching means, more particularly for use with electric motor control systems
IPC: B60L15/12
Filed: 1938-10-14
Abstract: 521,195. Master control of D.C. motors. GENERAL ELECTRIC CO. Ltd., and CROFT, E. H. Oct. 14, 1938, Nos. 29824 and 36686. [Class 38 (iii)] A controller is retarded in its forward motion by an escapement controlled by armature current. In Fig. 1 the controller is urged forward by pneumatic means 4, or alternatively by a stallable motor or slipping clutch and is restrained by an escapement. 11, 12 rocked by coils 13, 14 in circuit with selector segments 19, 20 on the controller and the contacts of an accelerating relay 15. In Fig. 2, the drum 27 is urged forward by a spring 28 strained by a pedal 24 and restrained by alternately acting pawls 59, 60. The drum 27 in its forward motion energizes contactors to . exclude armature resistance from the circuit of the motor 6 and thereafter weakens the field 12, finally opening the field contactor 8. When contactor 17 closes, the coil 17C is maintained over contact 17NO until the controller is returned to "off" position thereby preventing reinclusion of armature resistance during regenerative braking. The pawls 59, 60 are alternately withdrawn from the drum 27 by energization of fingers 35, 36 and are prevented from operation by accelerating relay AR lifting its contacts 96 under the action of motor current coil 7 and biasing coil 91, the coil 91 is variably excited by drum 26 directly associated with the pedal, so as to give variable acceleration as described in Specification 521,192. Depression of pedal immediately after release causes drum 27 to move forward without restraint as motor current is so small that the relay AR does not even lift its contact 95. Rheostatic braking is under the control of a separate drum 21 which, on movement from its " off" position, energizes coil BC of contactor B, the interlocks BNC1, BNC2 of'which open the circuits of contactors controlled by the power drum 27, and the interlock BNO closes to maintain the contactor B operative until both controllers 21 and 27 are returned to their "off position.

Abstract: 1,219,772. Transistor pulse generator. O H. DRAGER, [trading as DRAGERWERKE HEINR. & BERNH. DRAGER]. 24 June, 1968 [24 June, 1967], No. 30097/68. Heading H3T. In a pulse generator the frequency is determined by the discharge time of one capacitor C1 and the pulse width by that of a second capacitor C2, both capacitors initially having been charged simultaneously and very rapidly in relation to the mark-space times. Considering T1 and T4 to be on and the other transistors to be off, C1 is charged sufficiently to turn on T2; this turns on T3 whose collector voltage then turns of T1 and T4. The capacitors C1, C2 are now rapidly charged via T3, L and either D2, T2 or D3, T5. When C1 fails to supply enough current to keep T2 conducting, T2 turns off, and so does T3, thus turning on T1 and T5 which constitute constant current discharging circuits for C1 and C2. T2 and T5 are turned off by the voltage on C1, C2 as the junction of L and C1, C2 goes negative upon T3 turning off. While T5 is off, T6 and T7 are on and an electromagnet M is operated. C2 discharges at a rate determined by P2 as well as P1 until T5 turns on, whereupon T6, T7 go off and deenergize electromagnet M. C1 continues to discharge at a rate determined by P1 until T2 turns on, and so does T3. The cycle then repeats with the frequency set by P1 and the mark space ratio by P2.
