Abstract: 1288420 Anti-theft devices JOSEF VOSS KG 29 Sept 1969 [28 Sept 1968 30 Aug 1969] 47871/69 Heading B7J [Also in Division E2] A steering column lock comprises a lock cylinder 2 and a bolt 8 which is withdrawable against spring action into the release position by means of a key actuated cam 5 movable with a barrel of the lock and which, after release, as a result of withdrawal of the lock key moves to a column locking position by spring-biasing in which position it is locked by a member 17 which is released by means of the cam. The bolt 8 comprises an apertured frame 9 and pivoted head which is retained in the withdrawn position by engaging one end of a spring urged member 20, when the key is inserted in the slot, withdrawing the key allows the other end to move into the slot and frees the one end from the bolt which is free to project under spring action into the steering column passage 6. The bolt is then locked by a head 15 of the spring biased member 17 engaging in a recess in the bolt frame 9. The bolt is released by turning the key in the cylinder to rotate a barrel 4 together with the cam 5 which displaces a follower 18 projecting from the member 17 from a recess on the cam and disengages the head 15 from the bolt recess. A shaft 11 projects from the cam to operate an ignition starter switch 13 the drum of which rotates with the shaft 11. In one modification, the locking member 17 is a spring-urged pin member which snaps behind a locking lug on the cam 5. In another modification the bolt supports a pivoted pawl which engages a step on an eccentric on the shaft to lock the bolt.

Abstract: 1,245,457. Linkwork. ELEKTROSTALSKY ZAVOD TYAZHELOGO MASHINOSTROENIA 11 Oct., 1968, No. 48301/68. Heading F2K. [Also in Division B3] In a method of pilger rolling, a blank is fed intermittently between a pair of rolls 5, each roll being continuously rotated in the same direction by a motor, but having a rotary speed which varies periodically during each revolution of the roll. A unit 2 between the motor and a pinion stand 4 converts the uniform speed of rotation of the motor into non-uniform rotation of the rolls. The rolls are arranged to rotate at a slower speed during the intermittent feeding of the blank between the rolls. The unit 2 can take several forms, a pair of elliptical meshing gears 7 and 8 being shown in Fig. 1. Alternatively, the unit incorporates a driving crank 45, Fig. 10, which rotates a forked member 47 by means of a slider 46, the distance between the axes of rotation of the crank and member determining the velocity characteristic of the unit. In a further form, Figs. 6 and 7, the unit includes a hollow driving shaft 28 which drives a coaxial output shaft 43. The shafts are provided with respective cranks 31 and 41 whose outer ends slidably co-operate with a common ring member 35. The ring member is rotatably mounted in a transversely adjustable housing 37. Adjustment of the housing varies the eccentricity of the ring member relative to the shafts, and hence the degree of non-uniform rotation of the rolls. The sliding connection between the cranks and the ring can be replaced by an equivalent arrangement incorporating links (Fig. 5, not shown).

Abstract: 1,017,095. Parametric amplifiers. TEXAS INSTRUMENTS Inc. Dec. 31, 1962 [May 22, 1962], No. 49036/62. Heading H3B. A forwardly biased PN junction device is used as a resistive load in the idler circuit of a reactance amplifier. Resistance is employed to restrict the output to the amplifying range. A PN junction device gives less noise than a normal resistor. As shown in Fig. 1, the non- linear element of a reactance amplifier is a reverse biased varactor 59. Tank circuits with reactive elements 50 and 51, 52 and 53, 57 and 58 are tuned respectively to the signal, idle and pumping frequencies. Across the tank circuit timed to the idler frequency is connected a PN junction diode 54 forwardly biased by a current source 56. The amplified signal is fed to a receiver load 64. In Fig. 2 (not shown), a bridge circuit including reverse biased variable capacitor diodes 104, 106 is pumped from a source 100 so as to constitute a varying capacity across the tank circuit 110 and a capacitor 113. The tank circuit is timed to the pump frequency. The input signal is applied across the capacitor 113. The output signal is coupled to the forward biased base emitter PN junction of transistor 120.

A pressure plate 30 urges the stack in a forward direction, the plate 30 being biased by the pressure roller 33 of a yoke 32. In order to remove the foremost paper from the stack 24 and to push it through the slot 29 the appropriate coins are inserted in a device 20 so that the user can then pull a handle 2 and an operating rod 3 outwardly of tha receptacle 1, outward movement of the rod 3, which slides on a guide surface 7, causing clockwise rotation of a link 6 which in turn causes clockwise rotation of a bell crank lever 9, 9<SP>1</SP>, the arm 9 being mounted by a pin 11 in a slot 12 forward in a frame 13 so that the latter is moved upwardly. As shown in Fig. 3 a carrier 40 is mounted on the frame 13 and has a pair of needle carriers 41, 42 pivotally mounted thereon which respectively carry needles 45, 46 which are biased inwardly by respective springs 43, 44 the needle 46 extending through an opening 50 in the front wall 25, while a transverse pin 47 which engages a guide surface 48 maintains the needle 45 out of engagement with the foremost paper. When the frame 13 initially moves upwards the needle 46 slides along the foremost paper, and when the pin 47 engages the part 48<SP>1</SP> of the surface 48 the spring 43 causes clockwise rotation of the carrier 41 such that the needle 45 engages the foremost paper and moves it upwards whereby its lower edge clears the ledge 27 and rotates forwardly. When the handle 2 is then pushed back inwardly the needle 46, due to its resultant downward movement, pushes the foremost paper downwardly so that its lower edge passes through the slot 29, to be grasped by the purchaser. A further pair of needles 45, 46 (not shown) is provided adjacent the other edge of the front wall 25 of the machine.
