Abstract: 1,124,800. Pick-up arm assembly. BSR Ltd. 12 Dec., 1968 [31 Dec., 1965], No. 55330/65. Heading G5R. In a pick-up arm assembly, the arm 18 is provided with a calibrated spring which acts in opposition to counterweight 21 to increase the pressure exerted by the pick-up on a record. The arm 18 is supported in body member 16 which is horizontally pivoted in a U-shaped support 15 which in turn is vertically pivoted 14 to the base 11. The weight of the arm is counterbalanced by weight 21 which is coarsely and finely adjustable in position. An externally calibrated sleeve member 39 is rotatable relative to the body member, to one of a number of detent defined positions and carries an anchor post 50 on its inner surface. This post engages one end of a spring 53 which passes around a shaft passing coaxially through the body member and through an aperture 20 in the body member to an anchor point on the U- shaped member 15. The spring pressure is determined by the position of the rotatable sleeve.

Abstract: 1,195,297. Template followers. BÍLKOW G.m.b.H. Dec.20, 1967 [Dec. 22, 1966], No. 57948/67. Heading G3N. A copying machine tool, of the type having a number of tools which can be radially positioned against an axially symmetrical rotating workpiece and moved by a feed device in the direction of rotation, is characterized by a tangent sensor, associated with the copying sensor which is angularly positioned to the template contour and controls the staggering of the tools. As shown, a workpiece 40 is processed by pressure tools 1-3. Each tool comprises a piston K1-K3, connected with the machine frame, a cylinder Z1-Z3, displaceable with respect to the piston, and a pressure roller R1-R3, connected with the cylinder. The movement of the pressure tool 1 is controlled by a copying sensor 5 following the contour of a template 4. Deviation of the sensor 5 from a central position actuates an hydraulic valve 6 controlling the movement of the cylinder Z1 through lines 7. The position of the cylinder is transmitted mechanically, through a rod system 8, to retro-actively position the housing of the valve 6. The pressure tools 2, 3 are positioned in correspondence with the movement of the tool 1 through racks 11, 13 and racks 12, 14 differential movements of which causes displacement of pinions 15, 23, mounted in housings 16, 17. Displacement of the housings actuates sensor pins 18, 19 of hydraulic valves 20, 21 which adjust the position of cylinders 22, 23 in accordance with the movement of the cylinder Z1. A forked sensor 26 is associated with the sensor 5 and angularly positions a potentiometer 28 in dependence on the gradient of the template contour. Signals from the potentiometer are fed to a variable amplifier 30, programmed in an unspecified manner, whereby radial stagger signal are generated which control motors 33, 34 adjusting spindles 22, 23 coacting with the sensors 18, 19, and axial stagger signals are generated which control motors, not shown, axially adjusting the rollers R2, R3 through screw spindles. In modifications, the forked sensor 26 is combined with the copying sensor 5 to provide a measure of the template gradient at the copying point or at a point in advance or behind the copying point to provide a lead or lag for the radial and axial stagger control.

Abstract: 1309957 Gas lighters J G TRICOT 16 Dec 1970 [6 Feb 1970] 59632/70 Heading F4F A flame adjusting device in a gas cigarettelighter of the type having a valve body 4 screwed in a well 3 formed in the upper portion of a gas reservoir 2, the bottom of the well communicating with the reservoir via a bore 15 housing a wick 16, comprises resilient lugs 10 positioned at the bottom of the well and disposed at spaced angular intervals about an extension of the axis of the bore together with a tapered seat member 11 which moves longitudinally in the well and caps the lugs to move them more or less towards one another thus modifying the cross-section of the passage defined by the lugs for the flow of gas. The tapered seat 11 is connected to the valve body 4 and is moved by screwing the valve body, which houses a valve 5 terminating in a burner 6, in and out of the well 3. In Fig. 3 the lugs 10 have a cross-section of a sector of an annulus, each having a part cylindrical surface 13, these surfaces together forming a substantially cylindrical passage which receives the upper end of the wick 16, movement of the lugs throttling the wick to a greater or lesser extent. In an alternative embodiment, the upper end of the bore 15 is reduced to a capillary orifice (18), Fig. 6, not shown, and each lug has a cross-section of a sector of a circle, Fig. 7. The gas flow is therefore controlled, not by throttling the wick, but by modifying the gas flow passage formed by the lugs. In a further embodiment, Fig. 11, the lugs have a cross-section of a sector of an annulus for most of their height, but at the top have a cross-section of the sector of a circle. The gas flow is controlled partly by throttling the upper end of the wick and partly by modifying the gas flow conditions in the lower and upper part of the passage respectively.

Abstract: 1458834 Electronic watches FAIRCHILD CAMERA & INSTRUMENT CORP 28 Dec 1973 [2 Jan 1973] 60023/73 Heading G3T [Also in Division H2]  An electronic watch comprises means 12...18 for providing low voltage time signals, means 27 responsive to said low voltage time signals for converting the D.C. voltage from a battery 26 to a higher D.C. voltage and level converters 20, responsive to the higher D.C. voltage for increasing the magnitude of the low voltage time signals for application to a liquid crystal display D. As described, an oscillator 10, controlled by a crystal 12 operates at a frequency of 32, 768 Hz and feeds a divider 14 which produces pulses at 1 Hz, 32 Hz and 64 Hz for feeding a time keeping unit 16, Figs. 3 and 4 (not shown) from which a de-coder 18 provides appropriate low voltage minutes and hours signals which are increased in voltage by means of level converters 20 so as to be suitable for gating to the respective segments of a 7-segment liquid crystal display D. Gates 22 are operated by the 32 Hz time signal which is also fed to the common electrode 30, individual segments 24o ... 24i being displayed or not depending whether they are driven antiphase or in phase with the signal on the common electrode 30. (Figs. 3 and 4) relate to block diagrams to show how counters in the time keeping unit 16 can be manually reset to adjust the hours and minutes. Fig. 7 (not shown) relates to an integrated circuit using complementary metal oxide semiconductors (CMOS) for the level converters 20. D.C.-D.C. converters. Fig. 6 shows details of block 27 for converting the battery voltage VD (1.5V) to V D ' (15V). When a clockpulse is received by gate 80, CMOS transistor 50 is turned off and 51 turned on, turning on transistor 52 which passes current via inductor 53. At the end of the clockpulse, transistors 50...52 change state, so that the resulting high voltage across inductor 53 is rectified at 54 and charges capacitor 55. Automatic voltage control. A constant current source 41 is driven by the output of a JK flip-flop 87 so as to provide 1ms constant current pulses in resistor 42 at 4 Hz. The lower end of resistor 42 is connected to the output of the D.C.-D.C. converter at 57 so that the voltage at 45 will be indicative of the converter output. Terminal 45 is coupled to a sensing transistor 76 via a source follower 75 having a further CMOS transistor 72 as its source load. When the voltage at 57 reaches a predetermined value, transistor 76 is turned off and flip-flop 77 set by the next clockpulse from 87, so as to block NOR gate 80 and inhibit the D.C.-D.C. converter 44 until its output 57 has fallen to a further predetermined value. The output voltage at 57 is thus regulated by comparing it with the voltage pulses across resistor 42 applied by constant current sampling pulses. CMOS transistors 60..62 provide a bias voltage at terminal 63, slightly lower than the output voltage 57.
