Title: Improvements in or relating to shift registers
IPC: G11C19/28
Filed: 1960-01-27
Abstract: 922,629. Transistor pulse-circuits. TELEFONAKTIEBOLAGET L. M. ERICSSON. Jan. 27, 1960 [Jan. 27, 1959; Jan. 13, 1960], No. 2972/60. Class 40 (6). [Also in Group XIX] A shift register includes in each stage a blocking oscillator comprising a transistor and a transformer, the transformer having an additional secondary winding forming part of an energy accumulating circuit arranged to feed at least part of the energy accumulated during the operation of the stage to the base of the transistor of the next stage which is thereby primed. Three shift register stages B1, B2, B3 are shown, Fig. 1, each stage including a transistor T and transformer Tr, the transformer windings Nb, Nk forming, with the transistor T, a blocking oscillator. Switches S1, S2 are arranged to connect the stages alternately to a negative potential source. Assuming that the switch S1 is closed and the blocking oscillator of the stage B1 is operative, a secondary winding Nm feeds a pulse to the stage B2 which charges a capacitor C in that stage. The discharging current from the capacitor C maintains a base current in the transistor T of the stage B2, so that when the switch S2 is closed, a collector current flows through this transistor causing the blocking oscillator in the stage B2 to operate. In this manner the " operated " state is shifted along the stages. In the shift register circuit shown in Fig. 2, the capacitor C is eliminated. Assuming the switch Sl, Fig. 2, to be closed and the blocking oscillator of the stage B1 to be operative, at the end of a pulse, the transistor T is cut-off and simultaneously the switch S1 is opened, the collector current ceasing suddenly and the magnetic energy stored in the winding Nm causing an emitter base-current in the transistor T of the stage B2, closing of the switch S2 resulting in the blocking oscillator in the stage B2 becoming operative. A modification in which each stage is connected to both switches S1 and S2 is described (Fig. 3, not shown). In a further modification (Fig. 4, not shown), an additional transistor is provided in each stage, the base current of which constitutes the load for that stage.

Title: Means for preventing unauthorized use of motor vehicles
IPC: B60R25/00
Filed: 1951-02-09
Abstract: 687,440. Locking brake levers. SILK, W. F. Aug. 8, 1951 [Feb. 9, 1951], No. 3207/51. Classes 79 (iii) and 79 (v) [Also in Group XXXIV] A hand operated brake control mechanism for a motor vehicle, comprises a brake operating rod or lever, a detent for releasably securing the rod or lever in the " on position, a member which is carried by the rod or lever and movable relative thereto to release the detent, a key actuated lock barrel rotatably carried by the detent-releasing member or by a member for actuating the detentreleasing member, and means rigid with the barrel and rotatable therewith into and from a position in which the means referred to prevents movement of the detent-releasing member to release the detent by engagement of the means with the rod or lever or a part carried thereby from and into a position in which the means permits such movement. In the arrangement shown, as applied to a hand brake control mechanism of known construction in which a pawl 4 engaging ratchet teeth 6 is pivoted to a brake operating member 2 terminating in a hand grip 3 and in which the pawl is released by depression of a trigger 12 to move a spring loaded rod 13 and an actuating member 8, a key operated lock barrel 16 is rotatably mounted in a housing 18 in the trigger and includes an axially extending spigot portion 20 which is rotatably mounted in the trigger. The outer end of the spigot is riveted over to secure the lock barrel to the housing against axial withdrawal therefrom. A diametrically extending lug 21 on the inner end of the spigot 20 allows the trigger to be depressed to actuate the member 8, when the lock barrel is moved to a position in which the lug 21 is aligned with a recess defined by parallel side walls in the hand grip 3. Rotation of the barrel 16 beyond the positions corresponding to the locked and unlocked positions is prevented by a shoulder 22 with which the lug 21 engages. The barrel 16 comprises spring pressed locking pins (not shown) co-operating with slots in the housing. The invention is applicable to a brake control mechanism in which the brake actuating member is pivotally mounted with respect to a supporting member. The detent-releasing member may be directly manually operated, a projecting end of a rod within an operating lever having a cylindrical housing for a lock barrel which extends at right angles to the rod and the barrel having a radial lug which extends through a recess in the housing for engagement with the lever or a part carried thereby from and into a position in which it permits depression of the rod to release the detent.

Title: Improvements in web supply apparatus
IPC: B65H19/18
Filed: 1952-02-07
Abstract: 722,534. Feeding webs. SCHNELLPRESSENFABRIK FRANKENTHAL ALBERT & CIE AKT.-GES. Feb. 7, 1952 [Feb. 14, 1951], No. 3212/52. Class 100 (1). [Also in Group XL (b)] An apparatus for splicing the free end of a new paper web roll to the expiring end of an exhausted roll being fed to a machine fed with paper web, includes a device wherein, through a control element, the rotation of the new roll controls the intensity of a beam of light falling on a photo-electric cell responsive thereto, the cell being connected, through an amplifier, to actuate relays and cause electromagnets to effect splicing and subsequent severing of the webs by a brush and knife respectively. A roll-supporting spider comprises arms, 7 ... 12, which support paper rolls 19, 20 and 21. The arms 7, 8, 9 are carried by a support 5, while the arms 10, 11, 12 are carried by a support 6, the supports 5 and 6 being axially displaceable along a shaft so as to accommodate rolls of varying width. The replacement roll 20 is accelerated to the linear speed of the web 29, unwound from the expiring roll 21, by means of a belt 22 mounted on a frame 28 and driven from the printing machine. The frame 28 is lowered prior to a splicing operation by a lever 73 actuated by a crank-pin 72 rotated by gearing 70, 68 having a ratio corresponding to the number of paper rolls carried by the spider, i.e. 1 : 3 in the present case. A pulley 48 having a reflecting surface with a darkened part 49 is mounted on spindles supporting one end of each roll. The pulley 48 thus reflects a light beam from a light source 50 to a photoelectric cell 51 until the part 49 interrupts such reflection, the part 49 being circumferentially spaced a predetermined distance from the free end 35 of the roll 20. When a switch in the photo-electric cell 51 circuit is closed, the part 49, due to the interruption in the light beam, causes the cell 51 to release a current impulse, which when amplified, operates in succession two electromagnets 41 and 47. The electromagnet 41 displaces a web deflecting brush 37 through a rod 40 and lever 39, while the electromagnet 47 actuates a web-severing knife 42 through a rod 46. The expiring rolls 20, 21, 22 are braked during unwinding by a band 61 engaging a brake disc 60, the band 61 being tensioned by a bell-crank lever 65 one arm 66 of which carries a weight 67, while the other arm 63 is secured to the band 61. The weight 67 only causes braking during downward movement, i.e. during unwinding of the rolls.
