Abstract: 1,050,214. Controlling friction clutches; cone and disc brakes. SPINDELFABRIK SUSSEN, SCHURR, STAHLECKER & GRILL G.m.b.H. July 6, 1965 [July 14, 1964; June 1. 1965], No. 28564/65. Headings F2C, F2E and F2L. [Also in Division D1] In a spinning &c. spindle where the driving wharve can be connected and disconnected from the spindle by an axially movable clutchelement, the latter can yield in a radial direction and is urged axially into the connecting position by a spring. In Fig. 1 (not shown), a clutch-member 2, consisting of three or more resilient segments providing a conical outer surface, is urged by a spring 3 against a conical inner surface of a wharve 1 and the outer surface of a sleeve 4 secured to the spindle. The segments are prevented from moving laterally by projections 6<SP>1</SP> on a ring 6 between the member 2 and spring 3. To interrupt the drive and brake the spindle, a sleeve 7 is lowered by operating a pivoted, bifurcated lever 8, so that its upper inclined end engages a second conical surface on the clutch-member ; the latter is thus moved out of contact with the wharve, but the opening causes the segments to remain in engagement with the sleeve 4 and brake the spindle. The lever is connected to an operating rod 11 and the force excited by the lever can be adjusted by nuts 808 bearing against a spring-cup 809. An overload protector 810 is provided. In modifications (a) the conical surface is on the inner sleeve instead of on the wharve, Fig. 2 (not shown); both the wharve and sleeve have conical surfaces and the member 2 is shaped correspondingly, while the braking-surface is on members depending from the member, which have downward extensions engaging slots in a flange on the bottom of the sleeve, Fig. 3 (not shown); the inner sleeve 4 may be dispensed with and the member 2 engages directly on e.g. an enlarged part of the spindle, Fig. 6 (not shown), and the separating projections 6<SP>1</SP> are on members which move in splines in the spindle, Fig. 7 (not shown), while the braking-sleeve is arranged to press, by a lever disposed above the wharve, downwardly on the top of the clutch member, a fixed braking-member 91<SP>1</SP> being also provided, Fig. 8 (not shown). Finally, for heavy duty, two springs 3 are provided, Fig. 5 (not shown), and when the sleeve 7 is operated and the clutch member 2 is lowered a ring 56 beneath it is lowered on to a fixed braking surface 57.

Abstract: 1,054,288. Moderator structures. NUCLEAR POWER PLANT CO. Ltd., and A.E.I.-JOHN THOMPSON NUCLEAR ENERGY CO. Ltd., [trading as NUCLEAR POWER GROUP]. Jan. 28, 1965 [March 19, 1964], No. 11758/64. Heading G6C. A moderator structure comprises an assembly of blocks arranged in vertical columns, one or both ends of each block being chamfered on at least two opposite sides of the block, the two chamfers on opposite sides of the block being in regions of different neutron flux. The object of the invention is to reduce the radial forces needed in the core to maintain the columns in alignment against the bowing forces which result from differential length shrinkage across the column width caused by the neutron flux. Fig. 2 shows a chamfered block for use in a structure according to the invention. Both ends of the blocks may be chamfered and they may be of other than square cross-section. The chamfers may be of such an extent as to move the point C on to the centreline. The blocks are preferably graphite, although the invention is applicable to any solid moderator subject to varying shrinkage with varying neutron flux.

IPC: H04L25/49
Abstract: 1,095,439. Data transmission systems. INTERNATIONAL BUSINESS MACHINES CORPORATION. July 25, 1966 [Oct. 15, 1965], No. 33321/66. Heading H4P. In a binary data transmission system a 1-0 transition is represented by a cycle of sine wave of frequency half the bit rate, and a 0-1 transition by the inverse of this. The store which holds the input data is read out at bit rate until a transition is detected, whereupon read-out is inhibited for the duration of one bit to allow the single sine wave cycle to be transmitted. At the transmitter, Fig. 2 (not shown), data from the input shift register passes to a bi-stable unit. Each transition in the output of this unit causes a first pair of mono-stable circuits to inhibit one register read out pulse and a second pair to enable one or another of a pair of gates. The gates are fed by sine waves 180 degrees apart, so that the gate outputs form the required signal for transmission as shown at C, Fig. 3 (part shown). The data it represents is shown at OUT; a dash indicates no read out after each transition. At the receiver, Fig. 4 (not shown), the signal is passed direct and via a half-cycle delay and inverter to a summing circuit. The resultant waveform, Fig. 5 (part shown), feeds units which have positive and negative thresholds as shown. Their outputs are gated to a bi-stable unit which provides the output data. The threshold units are inhibited for a duration indicated by the arrow 210 after each threshold crossing, to prevent response to noise which may cause the threshold to be crossed in the second half of the cycle, e.g. 202. Means is also provided to prevent response to noise on any non-significant half cycles, e.g. 216, which precede the significant ones, e.g. 204.

Abstract: 1,143,758. Semi-conductor filter circuits. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 11 Nov., 1966 [16 Nov., 1965], No. 60687/66. Heading H3T. A low-pass filter for digital pulse signals from a source 1 synchronized by a clock pulse generator 2, comprises a shift register 3, the contents of which are shifted by a frequency multiplier 10 with a shift period smaller than the minimum pulse period, the elements of the shift register being connected through attenuation networks 21-27 to an adding device 20 which provides the output signal. The filter has a linear phase-frequency characteristic, and an amplitude-frequency characteristic which can be varied by a suitable selection of the values of the attenuating resistances 21-27; by providing phase-inverters 28-34 at the outputs of the shift register stages, a wider range of amplitude-frequency characteristics is made available. An output filter 19 eliminates higher frequency pass-bands. The same shift register may feed two different combinations of attenuation resistances and phase-inverters to provide two quadrature phase output signals which can be used in a single sideband modulator, Fig. 9 (not shown). The shift register is shown in Fig. 4, as a series arrangement of stages which may be bistable circuits, but may alternatively be a parallel arrangement, Fig. 8 (not shown). The circuits may be constructed as integrated circuits.

Abstract: 1,227,726. Automatic speed control. TOKYO SHIBAURA ELECTRIC CO. Ltd. Feb. 7, 1969 [Feb. 9, 1968], No.6649/69. Heading G3R. In a closed loop control system, e.g. for controlling the speed of rotation of a turbine 10, two systems are provided for detecting the error, one of which is arranged to give a high output if it fails and the other to give a low output if it fails, the latter having an offset so that under normal conditions it always produces a higher output than the first, and means 13 for detecting the lowest of the signals and using it to control the variable. The turbine 10 drives a generator providing speed dependent A.C. signals in detectors 11a, b which are converted to voltages at 22a, b. The speed dependent voltages are compared with a set speed value from 24a, b in adding circuits 23a, b. A small bias 25 is added to the output of converter 22b which has the same effect as providing a slightly higher set speed signal from 24b. The outputs of adders 23a, b are applied to a low value gate 13 which passes only the lower of the two signals, i.e. normally that from 23a, to a servomotor system 14-16 controlling a valve V to adjust the turbine speed. If the "a" system should fail its output C will rise and low value gate 13 will then select the output D of the "b" system. If the "b" system then fails the turbine speed would be lowered until it came to rest. If a difference occurs between the outputs of adders 23a, b greater than that set by 25 then a circuit 29 operates an alarm. If either of the outputs changes more rapidly than a set value dependent on the inertia of the turbine, then circuit 26 issues a signal to operate the alarm and also to trigger the gate 13 to only accept the other output. If the rapid change continues for too long a time limit circuit 27 causes the valve to be closed. In a modification Fig.2 (not shown) a rate of change detecting circuit (26a, 26b) is included in each system and if both give an output a device (30) is arranged to stop the turbine. In an alternative arrangement Fig. 3 (not shown) the low value gate 13 receives the outputs of the converters 22a, 22b direct, and feeds a single adding circuit 23.

Abstract: 1289401 Pulse doppler radar WESTING- HOUSE ELECTRIC CORP 3 July 1970 32349/70 Heading H4D [Also in Division G1] A system for analysing the frequency spectrum of a signal, e.g. a received pulse in a pulse doppler radar, of the type in which the received signal is applied to a plurality of contiguous band pass filters, is characterized in that by means of a single multistable state magnetic core the output of each filter is clipped, integrated and stored. The principle of the invention can be simply stated as follows. If a magnetic core having a rectangular hysteresis loop, Fig. 4, is set in its negative saturation remanent condition -B 2 , then to cause the core to change its state a flux larger than its threshold flux H 0  must be applied. Moreover, when such a flux is applied the extent by which the magnetic state of the core rises depends directly upon the time integral of the flux. Thus if a suitable bias flux H 1  is applied to the core together with the output signal from a filter, then the extent by which the magnetic state of the core rises above its negative saturation level -B 2  will be proportional to the sum of the areas of the signal shown cross hatched, i.e. the signal will have been clipped, integrated, and the integral will have been stored. At the end of a received signal every core can be reset to its negative saturation state to provide an output pulse whose amplitude will represent the energy of the input signal lying in the associated frequency band. The preferred embodiment, Fig. 7, uses the technique described in U.S.A. Specification 3,461,407 whereby an array of n crystal filters 90 are shared in adjacent pairs to provide n-1 band pass channels. Each channel includes one magnetic core 82 to which are coupled the associated crystal filters 90 by oppositely poled windings 80, 81, a bias winding 93, a reset winding 86, and a common series-connected output winding 92, 90. In operation at the end of an input signal the cores are reset sequentially by an interogator 16. By using individual output windings parallel read out is possible.

To read or write in a given line, the appropriate pair of transistors and current source are rendered conductive, the circuit being such that the transistor base currents do not flow in the line, and hence the line current is independent of transistor variations. For clarity, the corresponding drive circuitry for the row lines of the planes n to n + 3 is not shown. To pass a current through line 31 from source 33, the source is activated, and the bases of transistors 46 and 48 are pulsed by a selecting gate 53. A pulse is also applied to the base of transistor 45 by appropriate selection circuitry (not shown). A current of reverse polarity may be obtained by activating source 35 and transistors 46, 48 and 47. In Fig. 3, the number of lines is increased by a corresponding increase in transistors 46 and 48 and their gates 53. Any number of lines may be driven by further increases in these components.
