Title: Improvements in or relating to telephone systems
IPC: H04M19/04
Filed: 1960-12-01
Abstract: 964,335. Substation circuits; transistor oscillator circuits. WESTERN ELECTRIC CO. Inc. Dec. 1, 1960 [Dec. 16, 1959], No. 41337/60. Headings H3T, H4K and H4R. A telephone substation circuit comprises a direct current path including a non-linear impedance element 23, a multifrequency oscillation generator 15 including a frequency determining resonant circuit and an amplifier 71, the output of the amplifier being connected to the direct current path, and switching means operable to select the frequency of oscillation of the frequency determining resonant circuit and simultaneously connect the non-linear impedance element 23 to provide operating bias for the amplifier 71. Two tone V.F. signalling is used and the substation is fed by direct current through a pair of line conductors L1, L2 from a central office 13. The direct current path includes induction coil L, comprising series aiding windings 20, 21, 22. Between line conductor L2 and earth is a conventional telephone ringer 14. Lifting of the handset closes switch-hook contacts 11, 12 and supervisory currents flow from line L1 through winding 20, contact 33, transmitter 31 and resistor 30 to line L2. Speech signals at transmitter 31 are introduced into induction coil 21 and fed by auto-transformer action employing windings 20, 21, 22 to line conductors L1, L2. Anti-side-stone network 36 prevents these speech currents from reaching receiver 46 but incoming speech over line conductors L1, L2 is not balanced out and is audible at receiver 46. The calling mechanism employs at least ten push-buttons, the operation of any one of which causes the generation of two tones. Operation of a push-button actuates one crosspoint switch 68, one crosspoint switch 69 and a common switch 34 which includes contact 50. Switch 34 is shown in the normal (speech) position. Switches 68, 69 close taps corresponding to a pair of frequencies indicative of a digit and switch 34 inserts attenuation in the receiver circuit by opening contact 50. The interruption of direct current through windings 61, 62 by opening of contact 64 shock excites windings 61, 62 at frequencies determined by resonant circuits comprising tapped portion of winding 61 and capacitor 66 and tapped portion of winding 62 and capacitor 67. Transistor 71, acting as a class A amplifier, sustains the oscillations, windings 61, 73, 84 being inductively coupled, also windings 62, 74, 85. The output of transistor 71 appears across conductors 86, 60. The voltage amplitude of the calling signal is increased by transformer action of windings 20, 21, 22. Non-linear resistor 23 is a silicon carbide variator and is shunted by capacitor 40 which offers frequency compensation in the calling signal. Varistors 23, 26 also assist in loop equalization. Specifications 854,375 and 873,189 are referred to.

Abstract: 1389798 Storage cabinets SPERRY RAND CORP 4 Sept 1973 [5 Oct 1972] 41444/73 Heading A4T [Also in Division B6] A mechanized storage cabinet comprises a motor driven multiple carrier revolving storage mechanism and a control device, the control device comprising a selection device capable of receiving input signals to control the movement of the carriers 1 to an access opening of the filing cabinet, a U-like proximity switch 23 mounted in the cabinet and able to control the switching off of the motor, and an actuating member 19 for each carrier movable with its corresponding carrier without touching the arms 25, 26 of the proximity switch so as to actuate the switch for interrupting the motion of the carrier after its selection and transport to the access opening. The carriers 1 are carried by levers 3, 5 from endless chains guided over upper and lower sprockets, the lower sprockets being driven by a motor. A further level 9 on each carrier has a roller 11 guided by a rail 13. Each carrier 1 carries an adjustable plate-like member 19 which can pass with clearance in both directions 31, 33 between the arms 25, 26 of the proximity switch mounted on the cabinet. The switch may operate by influencing an electromagnetic oscillating circuit, or by interrupting electromagnetic waves transmitted from an emitter in one arm to a receiver in the other.

Title: Improvements in bearing arrangements for spinning or twisting spindles
IPC: F16C27/08
Filed: 1959-12-08
Abstract: 894,688. Yielding bearing supports. WURTTEMBERGISCHE SPINDELFABRIK G.m.b.H. Dec. 8, 1959 [Dec. 27, 1958], No. 41625/59. Class 12 (1). In a bearing arrangement for spindles of spinning or twisting machines having neck and foot bearings for each spindle separately mounted within a housing 6, the foot bearing 1 is mounted without radial play within a damping element comprising a spiral spring 3 centrally supported in the housing. The spring 3, Fig. 1, is mounted in a sleeve 4 received by the housing 6, and the bearing 1 inside the spring is slidably supported by a member 2 which is also in the sleeve 4. A flanged centring-ring 5 is fitted into the sleeve 4 and into the spring 3. The bearing 1<SP>1</SP>, Fig. 2, is prevented from rotating by a tube 7 having an inwardly-bent longitudinal edge portion 8 and upper and lower inwardlybent tabs 9 which engage slots 10, 11 in the ring 51 and bearing 1<SP>1</SP>. In an alternative method of locking the foot bearing against rotation, the spiral spring, which is inserted directly into the housing, has a tab 12, Fig. 3, which engages a recess 13 in the foot bearing. The centring- ring 5<SP>11</SP> is held against a stepped portion of the housing 6 by a coil-spring 16. In an embodiment, the bearing 1<SP>11</SP>, Fig. 4, is received by an extension tube 14 of a synthetic plastics centring-ring which is held by a spring-ring 15. In another embodiment the centring-ring 5<SP>111</SP>, Fig. 5, is held against a step in the housing by a coil-spring 16<SP>1</SP>. Rocking movement is facilitated by clearance being provided between the ring and the housing, and by the ring having a tapered portion.
