Abstract: 1,233,572. Snap-action switches. MOLEX PRODUCTS CO. 4 June, 1968 [21 March, 1968], No. 26545/68. Heading H1N. A push-button switch of the successiveactuation type comprises a rooking contact member 50 pivoted at 49 on a framework providing a terminal 20 and a seat 20a for an over-centre compression spring 55 which alternately maintains contact ribs 53, 53a in engagement with fixed contact strips 45, 45a respectively. The button 14 alternately rocks member 50 by the intermediary of a T-shaped actuator having a shank portion 36 and a head portion 35, the latter being capable of rocking on a shoulder 34 of button 14 so that shank 36 does not have to bend to follow the movement of rocker 50. A spring 40 urges the actuator against the button 14 and thus provides restoring force for the latter. Slots 64, 64a in the hollow rectangular button 14 allow it to move over a fixed indicator lamp 57. The components are snugly fitted in recesses of the housing and retained by a cover (12, Fig. 1, not shown), which is sealed to the periphery of the housing. Integral resilient tongues 21, 21a serve to mount the switch in an apertured support.

Title: Apparatus for addressing a memory of selectively controlled rates
IPC: G10H7/04
Filed: 1971-08-25
Abstract: 1317385 Function generators; memory addressing; electrophonic musical instruments NORTH AMERICAN ROCKWELL CORP 25 Aug 1971 39946/71 Headings G4A G4C and G5J A memory is addressed at a sequence of storage locations by adding an incrementing number iteratively to the contents of an address register, the rate at which the iterative additions take place and/or the incrementing number being variable. In the particular embodiment described the memory is a read-only store which holds digital representations of evenly timespaced samples of a predetermined waveform to be produced by an electronic organ. By varying the incrementing number, the frequency of the note produced can be altered. A multiplexed pulse train representing the operated/unoperated keys of the organ causes gate 106, Fig. 8A, to be opened at a point in the multiplex cycle corresponding to an operated key. A register 102 is reset to a predetermined number at the start of the multiplex cycle and thereafter in each multiplex time slot, the contents are multiplied (or divided) by the twelfth root of 2 and restored in the register 105. Thus the number gated out at 106 depends on the position of the pulse in the multiplex cycle and thus on the particular note represented. The incrementing number is gated out from register 108 into the address register 109 at regular intervals, only a relatively small number of bits towards the least significant end of register 109 being used to address the read only memory 101. The incrementing number and memory 101 may be shared by 12 tone generators to which the outputs of memory 101 are distributed in sequence. An arrangement is described for assigning each note-representing pulse in the multiplex train to the next available one of the tone generators taken in sequence upon the first occurrence of the note pulse in a multiplex cycle, Figs. 7A, 7B (not shown). Generation of the incrementing number may be performed using a parallel or serial multiplier and provision may be made for controlling decay and attack. The data read out from the memory may represent the values of amplitude samples or the difference between successive samples.

Abstract: 1333546 Radio direction-finders MULLARD Ltd 10 May 1972 [2 June 1971] 21832/72 Heading H4D [Also in Division G4]  In a radio direction-finder there is a vertically extending rectilinear array which includes a plurality of pairs of equally spaced aerial elements, phase discriminator means to derive from each pair of elements a measure of elevation angle # of incoming waves, and means to derive the average of the measurements. The invention reduces errors due to ground-reflection. In a microwave embodiment the aerial elements at the L.H.S. have a spacing 16d (d=6À5 cms., frequency 5 GHz) for each of pairs 16/3 and 3, 16/C and C, 16/2 and 2, and 16/4 and 4; element 3 is spaced near to ground e.g. at a height of 12 cms. Items B are superheterodyne receivers all supplied in identical phase from a common local oscillator not shown. Discriminators D measure phase differences at an I.F., e.g. 40 Me/s., digitally, e.g. as described in Specification 1,191,831. Phases derived from the four widest spaced pairs are converted to four bit binary code in converters C and are averaged by addition and scale shift division in device A. Logic L resolves ambiguity and provides a ten bit binary measure of elevation angle.  Phase-measuring, Fig. 4.-A transmission line T is (3#)/8 long and has tappings E, F, G, H spaced apart by #/8; outputs from squarelaw detectors J are compared in subtractors S to yield the outputs as shown (i.e. phase digitized to within 45 degrees) for the indicated inputs to the line. Modification to Fig. 3.-The receivers B do not feed directly into discriminators D but the output from each receiver is applied to a phase modulator (PM, Fig. 5, not shown) consisting of a voltage-dependent resistor/capacitor phase shifter and a triangular 500 Hz waveform is applied thereto to effect a phase excursion equivalent to the digital interval of the phase discriminators (22¢ degrees). It is stated that by integrating over a number of pulses, phase measurement accuracy is improved. In an experiment two aircraft could be separated in elevation when the angle between them from the ground was greater than (0À1 degrees sec#).

Such sheets are applied in discrete lengths with their end portions overlapping. The cement is applied to the contacting surfaces of the longitudinal lapped edges 27 of one sheet 25, Fig. 6, and also forms a wedge surface 28 to provide a smooth external transition between the lapped surfaces. The next sheet 25 is applied over the first sheet with the overlapping ends 26 cemented and the overlapping longitudinal edges 27a cemented as with the first sheet. For pipe fittings such as elbow bends, Tees, Wyes, the fittings are ensheathed by such sheets in the form of two overlapping halves cemented together. For valves, a hole is cut in the sheet and an overlapping cap is cemented over the sheet to accommodate the valve stem. At the end of the insulation section end caps of such sheets, have overlapping rims which are cemented to the ends of the sheets ensheathing the insulation. The sheets are of highimpact-polystyrene or acrylonitrile-butadienestyrene, and are vacuum drawn. The cement solvent is methyl-ethyl-ketone mixed with one of the above resins. The insulation is of rockwool, asbestos, cork or fibre, diatomaceous earth or an expanded rigid foam of synthetic resin. The pipe is of black or glavanized iron.

Abstract: 1346623 Diversity reception systems MARCONI CO Ltd 30 March 1972 [3 Dec 1971] 56127/71 Heading H4L Base band signals are supplied to terminals 1A to 1D of a diversity receiver and supplied via muting circuits 2A to 2D respectively to a combiner 3. Considering channel A, a pilot signal is selected at 5A and supplied to a control circuit 7A. The noise level is detected at 8A and supplied to the control circuit 7A which controls the muting circuit 2A. The remaining channels are connected in like manner. Leads 11A to 11D are muting reference leads which are connected together via links 13A to 13D. In operation, if a pilot frequency is present at each of the inputs 1A to 1D none of the muting circuits is operative but when any pilot signal is lost the corresponding control circuit causes the appropriate muting circuit to operate. Loss of all four pilot frequencies, assuming links 13A to 13D are connected, renders all the muting circuits inoperative with respect to the pilot frequencies but controlled by the noise level so that any muting circuit associated with a path having a high noise level is operated. If links 13A to 13D are removed and leads 11A to 11D left floating, muting will occur in response to individual high noise conditions only. If the links are removed and leads 11A to 11D are earthed, muting will take place in response to individual loss of pilot signal only. Details of the control circuit are included, Fig. 2 (not shown), indicator lamps being operated in the case of loss of pilot frequency, high noise and operation of the muting circuit respectively.
