Title: Improvements in and relating to shock-absorbers and the like
IPC: F16F1/42
Filed: 1959-12-30
Abstract: 915,093. Resilient mountings; vibration dampers. WIGAN, E. R. Dec. 19, 1960 [Dec. 30, 1959], No. 44335/59. Class 108(3). In a device for absorbing shocks and damping vibrations a diaphragm 10 made, e.g. of rubber, is secured along its periphery within a body 20, Fig. 13, which incorporates means for generating a predetermined compressive stress between the periphery of the diaphragm and a central internally-threaded boss 47 which is moulded in a conical portion 84 and receives a threaded support spindle 50. The pre-loading can be carried out by radial contraction of a band 11, Fig. 7, which encircles an enlarged rim 19 of the dipahragm for clamping it against the outer surfaces of the body 20 and a co-extensive clamping ring 21. Alternatively the band 11, Fig. 9, is provided with a number of sleeves 25 which engages the diaphragm rim 19 between circumferentially spaced rim supporting lugs 24 on the upper end of the body. In other arrangements the rim on a centrally thickened part of the diaphragm can be squeezed respectively in a recess in the upper end of the body 20 or against a lower radial flange on an externally threaded boss 47 by means of a screw cap on a threaded clamping nut. Radial distortion of the diaphragm can be obtained by inflating a hollow diaphragm rim which is clamped within a tubular upper edge portion of the body 20. The support spindle 50, Fig. 13, threaded into a plate 51 screwed to a load 46 is axially adjustable to vary the stiffness of a support spring 54 which is constrained between an abutment 53 on the lower end of the spindle 50 and a base 48. In a vibration damper arrangement in which the diaphragm of an assemblage such as shown in Fig. 9 is held in a cage 55, Fig. 14, the internal compressive stresses of the diaphragm are adjusted to the natural frequency of weights 75, 76 in combination with leaf springs 60, 61 to damp out the frequency of unwanted vibrations. The weights 75, 76 are secured to a spindle 64 which is connected to the diaphragm and between the springs 60, 61 carried by a strip-like extension 56 of the cage 55 the tuning to the frequency of the mechanical vibrations being carried out by adjusting a nut 73 and correspondingly the reaction of a spring 71. In the arrangement such as shown in Fig. 13 the load may be slung from the diaphragm in which case the additional spring 54 would be a tension spring. The diaphragm 10 may also be replaced by a pair of relatively adjustable flexible diaphragms. Specification 665,741 is referred to.

Title: A signal sampling circuit
IPC: H04J3/04
Filed: 1964-11-06
Abstract: 1,079,026. Pulse modulation circuits, transistor gating circuits. STANDARD TELEPHONES & CABLES Ltd. Nov. 6, 1964 [Nov. 7, 1963], No. 45308/64. Headings H3T and H4L. In a circuit for sampling an input analogue voltage, the input signal is supplied via terminal 11 to the emitter of a transistor 32, which converts the input into an analogue current, the collector circuit being connected via transistors 35, 36 to earth or to a sampling capacitor 13 respectively. The biasing is arranged so that during the intervals between sampling pulses applied at 12 transistor 35 is conducting and transistor 36 non-conducting, and the analogue current from transistor 32 flows via transistor 35 to earth. When a sampling pulse V 12  is applied, transistor 36 becomes conductive to charge capacitor C13 and transistor 35 is cut off. Immediately preceding a sampling pulse a clamping pulse V 14  discharges the capacitor 13 via resistor 23 and transistor 22. The resulting signal samples are supplied via terminal 15 to a utilization circuit such as a pulse coder. In a modification, Fig. 4 (not shown), the functions of transistors 35, 36 are interchanged.

Title: Improvements in or relating to Circuit Arrangements for Monitoring the Signal State of Signal Lines and/or Switching Equipments.
IPC: H04Q3/54
Filed: 1968-09-27
Abstract: 1,187,184. Automatic exchange apparatus. SIEMENS A.G. 27 Sept., 1968 [29 Sept., 1967], No. 45879/68. Heading H4K. Circuits S1 to Sn, such as lines or switching equipment, when requiring service apply a signal to an associated ferroelectric or ferromagnetic gate A1 to An so as to pass bipolar pulses from a generator JG to a start circuit EM, the start circuit activating a scanner identifier AW which inhibits all the gates Al to An and removes the inhibition from the gates individually and in succession to determine which particular circuits are calling. Scanning may be over the whole group from a start to an end position or may halt on the last current demand to be satisfied, scanning being resumed from that position on the occurrence of new demands. If the number of circuits S1 to Sn is large, such as a thousand, the scanner identifier AW and the start circuit EM may be worked on a units, tens, and hundreds, basis. Two saturable core gates A are described. The gate shown in Fig. 2 comprises a single core normally biased from its associated circuit by a winding Ws so that the bi-polar pulses applied to winding Wt do not produce significant output in winding We. If the associated circuit requires service it interrupts bias to Ws so that output is induced in We and EM recruits AW to determine which circuit is calling. All gates are inhibited by bias on a common winding Wsp the gates being released from inhibition individually by reverse bias to windings Waw. The gate shown in Fig. 3 monitors circuits which normally provide no current in winding Ws of a core E so that bi-polar pulses in winding Wt produce output in We coupled to winding Ws of a core E2 to neutralize the bi-polar pulses applied to Wt of E2. Output winding We of E2 generates no significant current so long as Ws of E is not biased. If the circuit associated with the gate energizes Ws of E the neutralizing bias to E2 is removed and E2 produces output from We to signal the start circuit EM. Inhibition and successive release of individual gates is effected from AW with common windings Wsp and individual windings Waw as in the gate of Fig. 2.
