Title: Improvements in or relating to contact springsets for use with electrical switching apparatus
Inventor: SMITH SIDNEY REYNELL
IPC: H01H50/58
Filed: 1952-03-29
Abstract: 707,706. Electromagnetic relays. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd. March 29, 1952, No. 8051/52. Addition to 651,502. Class 38(5) The comb-actuated spring-set of the parent Specification is arranged so as to reduce the load of the " moving " or " lever " springs in the unoperated condition on the armature or operating member of a relay or switch. In Fig. 1, the comb 23 is relieved of the bias of lever springs 13, 15, 17, by insulating studs 30, 31, 32, which enable these lever springs to be supported by the fixed " springs, the latter co-operating with a buffer block (not shown). The lowest pair of contacts (i.e. the " x pair) are arranged to close first, the spring 10 having an embossed portion 34 which is maintained in engagement with the comb 23. The upper pair of contact springs 17, 18 are arranged to close last (i.e. as a " y " pair), the spring 17 having a cranked portion 35 so that it is the last to be engaged and moved by the comb 23. Fig. 2 shows a springset for use in a relay having two springsets and in which the initial load of the lever springs 36, 37 is supported by the comb 38 in resting on a fixed non-magnetic support 39. This arrangement permits the armature to operate the " x " pair of contacts in the other springset before being subjected to the load of the springs 36, 37.

Title: Pulse counting squelch circuit

IPC: H03G3/34
Filed: 1970-02-24
Abstract: 1283292 Muting; transistor pulse circuits MOTOROLA Inc 24 Feb 1970 [10 March 1969] 8723/70 Heading H3T In a muting arrangement for a frequencymodulation receiver, negative zero-axis crossings of the signal are detected by a detector 21, Fig. 1, and applied over a gate 22 to a counter 24. Positive zero-axis crossings are detected by a timer 20 which applies an inhibiting signal to the gate 22 during the period of reception of negative zero-axis crossings so as to prevent them reaching counter 24. The counter 24 then only receives spurious negative-zero axis crossings due to noise pulses which are integrated and used to mute the receiver. The negativezero-axis crossing detector comprises transistor 57, Fig. 2, which is normally biased conductive over resistor 51, the I.F. signal being applied to its base over a differentiating circuit comprising capacitor 50: the positive-going pulses which appear in the collector circuit are applied to the base of transistor 60 which with integrating circuit 63, 64 comprises the counter. The timer 20 includes a positive zero-axis crossing detector comprising transistor 30 to the base of which the I.F. signal is applied so that on positive zero-axis crossings the transistor 30 is driven conductive. The negative-going pulses appearing in the collector circuit are applied over capacitor 36 to bias back transistor 39: the collector of this is back-coupled over transistor 45 so that transistor 39 remains cut-off for a time-period determined by capacitor 36. During this interval transistor 54, which comprises the gate, is held conductive, clamping the potential at the point 58 to a low value and inhibiting conduction in transistor 60 and hence charging of capacitor 63. The voltage developed across capacitor 63 due to noise pulses falling outside the time-intervals at which point 58 is clamped is used to mute the audio circuits of the receiver.

Abstract: 1,043,126. Pulse radar. SOC. NOUVELLE D'ELECTRONIQUE ET DE LA RADIO INDUSTRIE. March 4, 1964 [March 5, 1963]. No. 9106/64. Heading H4D. In a secondary pulse radar for recognizing targets (I.F.F.) the reply signals are fed in parallel to means (0), Fig. 1, comprising a set of planes of ferrite cores for storing them after quantization in time for one repetition period of each interrogation mode and to a means (3) affording a predetermined delay, the output of the storage means for a first repetition period being compared (4) with that of the delay means for the next repetition period of the same mode. Non-synchronous I.F.F. responses, e.g. arising from another radar, are thereby eradicated. The delay introduced is the sum of the time spent in the read-in and write-out operatons in a cycle of storage means operation. In an embodiment, Fig. 2, for three interrogation modes-corresponding to three time intervals between beginning and end pulses of a reply signal-the received reply signals after amplitude (2) and time quantization (9) are written into (121, 122, 123) corresponding ferrite storage planes (141, 142, 143) by the outputs of AND circuits (110) fed with gate-control pulses from a circuit (10) itself controlled by " mode synchronizing pulses " (Sy 1 , Sy 2 , Sy 3 ) which also control AND circuits (111) fed from storage reading out circuits (131, 132, 133). The output from AND circuits (111) is fed to an AND circuit (15), together with the output of the time quantizer (9), and the output from AND circuit (15) is fed to a gate circuit (4) together with the amplitude quantized reply signals after delay of the latter by a line (3).
