Title: Radio direction finding
IPC: G01S3/20
Filed: 1976-12-02
Abstract: 1536960 Radio direction-finding DEFENCE SECRETARY OF STATE FOR 23 Nov 1977 [2 Dec 1976] 50368/76 Heading H4D Automatic radio direction-finding apparatus provides an estimate of the direction of arrival of a radio wave by processing the receiver output signal in a manner which simulates the methods of an operator presented with the same information in displayed form. The wide aperture directional aerial system 1 has a directional pattern of reception in a given plane which is substantially symmetrical about the direction of maximum sensitivity thereof in that plane and the output signal from receiver 4 is processed in apparatus 5 to compute the point about which the amplitude distribution of said signal is most symmetrical. Rotation of goniometer 2 rotates the directional pattern and a shaft encoder 15 produces a digital representation of the direction of maximum sensitivity. The receiver output signal is detected at 14 and converted in A/D converter 13 before feeding to computer 17 which processes the samples therefrom. Thus there is built up a stored digital representation of the amplitude distribution of the receiver output signals as a function of the goniometer rotor orientation. Further processing stages involve snap bearing estimates and a final bearing estimate, Fig. 4 (not shown).

Title: Improvements in and relating to apparatus for mincing minceable materials
IPC: B02C18/36
Filed: 1969-10-14
Abstract: 1,253,420. Mincing machines. A. STEPHAN U. SOHNE. Oct. 14, 1969 [Oct. 19, 1968], No.50446/69. Heading A4C. A mincing machine consists of two sets of cutting members through which meat passes in succession, the first set consisting of a fixed annular cutting member 7 within which an annular cutting member 6 is rotated on a shaft 3, said cutting members being coaxial. The second set of cutting members consists of blades 22 rotated with a cutter head 10 and held against a perforated plate 9 by the action of a spring 11 which at its end opposed to cutter head 10 bears against the adjacent face of cutting member 6. Fig. 3 and 4, (not shown), depict in detail the pivotal mounting of blades 22 on arms 20 of the cutter head by means of a screw (23), the degree of pivoting being controlled by the action of an adjusting screw 25 attached to arm 20 said screw being in contact with a cam 24 on that edge of blade 22 which is remote from plate 9. The cutter head 10 is mounted pivotally on a bush 15 by means of a surface 19. Meat to be minced is fed via a hopper 31 and a screw conveyor 4 to the first set of cutting members 6, 7 where preliminary mincing takes place, and it is then guided by cylindrical surfaces 27, 29 and a frusto-conical surface 28 to the second set of cutting members 22, 9 where further mincing takes place. On passing through the perforations in plate 9 the minced meat is ejected via outlet 30 by the action of a rotating disc 13 which supports radial vanes 17 which tend to emulsify the minced meat. Ribs, not shown, may be formed on the surface 29.
Patent GB-1523879-A (GB)
Title: Phase comparator
IPC: H03D13/00
Filed: 1975-10-15
Abstract: 1523879 Phase detectors POST OFFICE 15 Oct 1975 [22 Nov 1974] 50742/74 Heading H3A A comparator for comparing the phases of two input signals at 1, 2 comprises: means, e.g. zero crossing detectors 3, 4, for producing pulses whenever the instantaneous value of the respective signal crosses a reference level in a given direction; and means responsive to the time intervals between a pulse derived from one signal and a pulse derived from the other signal to produce a signal dependant on the magnitude and sense of the interval, the sense depending on from which input signal the pulse starting the interval is derived. The circuit is arranged to respond to rate of change of phase difference by including a counter which sets a time interval in which the phase error detected by the threshold circuit must be achieved. If it is not, the counter is reset to start another count period. The two signals 1, 2 whose phases are to be compared are fed to zero crossing detectors 3, 4 which produce output pulses at each positive going zero transition. The outputs from the detectors 3, 4 are fed to a circuit 6 which produces output pulses having a duration dependent on the time interval to be determined, and are also fed to a bi-stable sense detector 5 which produces a "0" or a "1" output depending on whether the interval starts from a pulse derived from input 1, or one derived from input 2. Depending on the output from sense circuits, one or other of two gates is opened to charge a capacitor in one sense or the other for a period depending on the duration of the signal from circuit 6. If the magnitude of the phase error reaches a predetermined limit within a predetermined time, the threshold circuit 16B provides an output which is positive or negative depending on the sense detector output. The comparator is used in a phase lock loop, the outputs increasing or decreasing the count in a divider 33. In order to provide rapid lock, the amount by which the count is changed is made initially high and is progressively reduced by a factor of 2.

Filed: 1964-12-16
Abstract: 1,080,349. Measuring frequency. BELL PUNCH CO. Ltd. Nov. 26, 1965 [Dec. 16, 1964], No. 51133/64. Heading G4H. Apparatus for measuring the frequency of an A.C. current comprises means to generate a signal representative of a predetermined time interval and means for counting the number of pulses received during this interval. The timing interval is established by applying the output of a tuning-fork oscillator 1, to a series of dekatrons 2-7. The output of the last consists of pulses of ten second duration on each of two leads. The A.C. current to be tested is applied via a frequency doubler 10 to an AND gate 11 opened by one of the ten-second interval pulses from the last dekatron. The output of the gate 11 is applied through a bistable 12, a drive valve 13, a gate 14 which halves the number of pulses, a further drive valve 15 to a decade counter 16. The cathodes of counter 16 are connected via AND gates 17, enabled by the other output from dekatron 7, and AND gates 18 enabled by the first cathode of dekatron 6. The arrangement is such that the counting process occupies the first ten seconds and, at eleven seconds, gates 18 open to apply the value in the counter 16 to a display, e.g. lamps 21, which may be as described in Specification 989,134. The counter 16 is connected to second and third decades the values of which are gated to displays in the same way. The counters are zeroized at 18 seconds.

In a vehicle braking system a valve assembly is controlled by a member 39 by signal pressure from a driver's valve and acting through an inclined plane 45 of which the inclination is variable either manually or automatically according to the load on an axle. Pressure sensitive means 13 is associated with the valve assembly and is subjected to the braking pressure at the outlet 32 via passage 16 and chamber 15 when the brake is applied and also to the force of a spring 21. Normally valve head 23 is held on the seat 24 to close communication between the inlet 29 connected to a pressure reservoir or accumulator and the outlet 32 connected to the brake cylinders, the hollow stem 10 being spaced from the head 23 to exhaust the outlet to atmosphere via channels 22, chamber 14 and openings 70, 72. Pressure fluid from a driver's valve moves the member 39 to the right on application of the brakes, the force of which is transmitted by members 38, 34 pivotally connected to a spindle 36 to move the stem 10 upwardly and so lift the valve head 23. Pressure fluid from the inlet can then actuate the brake cylinders. The braking pressure is communicated to chambers 15 and 26 to act downwardly on the two diaphragms 13, 25 to close the valve 23 when the required braking pressure is reached. The spindle 36 is provided with a roller 44 which rolls on a plane 45 the angle of which is varied automatically according to the load on an axle or is adjusted manually in dependence of the load.
