Title: Systems for measuring the resonant frequency of a body
IPC: G01H13/00
Filed: 1972-09-26
Abstract: 1419517 Acoustic measurement of physical properties UNITED KINGDOM ATOMIC ENERGY AUTHORITY 4 Dec 1973 [26 Sept 1972] 44377/72 Heading H4D In a system for monitoring the vibration frequency of a body (the resonant frequency of which may depend on temperature or some other environmental factor) a transducer arrangement transmits a vibration to the body and receives an echo from it, and a measure of the phase difference between the vibration incident on the body and the echo signal, which difference depends on the closeness of the vibration frequency to the resonant frequency, is obtained by counting the oscillations of a clock signal in the interval between the occurrences of first and second predetermined parts of the echo signal. The Fig. 6 thermometer includes a magnetostrictive transducer 2 linked by a waveguide 6 and coupler 8 to a temperature-responsive resonator 10. The composite echo pulse from the coupler and resonator is shown in Fig. 4 and includes a null region C associated with a phasechange dependent on the closeness to resonance. The time interval between two predetermined points such as zero cross-overs P and Q in the echo signal is thus a phase measure and is determined by a counter 23 receiving clock pulses from oscillator 14. Logic circuit assembly 17 identifies P as being the first (or other) zero-crossing occurring after a threshold amplitude L has been exceeded, and identifies Q as being the zero-crossing occurring n cycles of the vibration frequency later. The clock frequency is divided by 100 at 15 to provide the vibration frequency signal (Fig. 5) which is fed to logic 17 and is gated at 53 to form bursts for energizing transducer 2. Counter 23 can be arranged to read zero when the measured phase corresponds to the resonant vibration condition, decoded readings other than zero being used to energize lamps 25b indicating "non-resonance" and to control at 26 the oscillator 14 frequency such that the vibration frequency is slowly adjusted to resonance. The oscillator 14 frequency is monitored or recorded at 46, 48. The echo signal is monitored on an oscilloscope connected at 69.

Title: Automatic adjusters for brake systems
IPC: F16D65/14
Filed: 1973-09-21
Abstract: 1480741 Automatic slack adjusters; spot-type disc brakes GIRLING Ltd 20 Sept 1974 [21 Sept 1973] 44402/73 Addition to 1190841 Heading F2E The present automatic adjuster makes use of a phenomenon described in the main Specification, namely that when a screw thread connection between two members is under a given load a larger torque is required to turn the members relatively to one another in a direction against the load than in a direction with the load, it dispenses with the thrust bearing formerly found necessary as an abutment for the adjuster return spring, and it incorporates an anti-knockback device to prevent reverse rotation of one of the rotatable members. Construction.-A strut 18, non-rotatable, has a non-reversible screw thread connection 27 with a nut 24, rotation of the latter in one direction effecting adjusting extension of the device. Rotation of nut 24 in the opposite direction is prevented by a one-way clutch mechanism shown as an annular ratchet member 40 splined to nut 24 and having teeth facing teeth on an end closure 41 of a fixed "container" 32, and held against it by a wavy washer spring 42. The nut 24 is in turn surrounded by an annulus 28 with which it has a reversible screw thread connection 31 of greater pitch than that of connection 27. A friction surface 35 on annulus 28 engages a friction surface 36 on an inturned flange 37 of container 32. A coil compression spring 33 is located between a shoulder 38, extending from nut 24, and annulus 28. One end of strut 18 is a sliding fit in a reduced bore 22 of a cylinder body 15 and is engaged by a dolly 20 in turn engaged by a cam 19. In operation, when no appreciable wear takes place, hydraulic pressure applied at a space 23 urges a piston 12 to the left and urges the strut 18, nut 24 and cylinder body 15 to the right. There is no appreciable clearance at connection 27, but axial clearance is provided at connection 31 to determine normal brake slack (container 32 being force-fitted in piston 12). Spring 33 is compressed. If friction-lining wear takes place during brake application, the clearance at reversible screw thread connection 31 is first taken up, after which this connection causes a relative rotation between nut 24 and annulus 28 (to lengthen the assembly); it is the nut which rotates, around strut 18. When the brake is released, the clearance at the reversible screw thread connection 31 is transferred to the opposite flanks of the threads, and because of the excess travel which previously took place due to lining wear, the connection 31 causes a relative rotation between nut 24 and annulus 28 but this time in the opposite direction. Also, this time, the pressure at friction faces 35, 36 is relieved and the frictional torque is greater at connection 27. Therefore annulus 28 rotates on nut 24 to re-set the adjuster. The adjuster may be incorporated in a spottype disc brake.

Abstract: Novel phenylguanidines of the formula <IMAGE>  in which     X is a hydrogen or halogen atom, Y is a hydrogen or halogen atom or a halogen-lower alkyl, nitro, lower alkyl or lower alkoxy group and Z is a halogen-lower alkyl, halogen-lower alkoxy or lower alkylsulphonyl group or, if X and Y are not both hydrogen atoms, Z is a halogen atom, or a lower alkoxy, lower alkyl, nitro or cyano group,   and their non-toxic acid addition salts are obtained by reacting an acid addition salt of a corresponding aniline with cyanamide. The salts obtained can be converted to the free bases. Both are therapeutically useful as blood pressure-lowering (anti-hypertensive) and cardiovascular agents. They are also useful intermediates for the preparation of corresponding phenylamidine-urea compounds, possessing the same therapeutic properties.

Abstract: 937,858. Valves. ATELIERS DE CONSTRUCTIONS DE REMIREMONT. Dec. 14, 1961 [Oct.11, 1961], No. 44783/61. Class 135. A movable flap 1 is provided in a chamber 3 communicating with spacers containing valves 11, 11<SP>1</SP> which normally operate in unison either to supply compressed air to a device or to block the supply and connect the device to exhaust, the arrangement being such that if one of the valves 11, 11<SP>1</SP> is seized in the. supply position the flap 1 shuts it off from the channel 5 communicating with the device. When compressed air is to be supplied through the channel 5, for example to the clutch of a mechanical press, two magnets 12 and 12<SP>1</SP> are energized to open a pair of valves 10 and 10<SP>1</SP> permitting air from a supply passage 7 to flow through bores 8 and 14 to the underside of a pair of actuating pistons 9 and 9<SP>1</SP> for the valves 11, 11<SP>1</SP>. Air from the passage 7 now flows through the latter valves into the chamber 3 containing the asymmetrically pivoted flap 1 and into the channel 5. When the valves 11, 11<SP>1</SP> are again closed, air escapes from the duct 5 as shown by the arrows in Fig. 1. If one of these valves fails to close, the flap 1 is pivoted by the consequent pressure differential to a position 16 or 16<SP>1</SP> so that escape of air from the channel 5 is not impeded.

[Also in Division G1] Fuel is injected into the intake manifold 12 by solenoid actuated valves 13 fed by a pump 16 and the fuel pressure is controlled by a regulator 19 to a value exceeding the intake manifold pressure by a predetermined amount. The regulator 19 may comprise two chambers (51, 52) separated by a spring-biased diaphragm (53) with a cone (54) which controls the flow of fuel, fed to one of the chambers (52), through a return pipe 55 to the fuel tank 18. The other chamber (51) is connected to the intake manifold 12. The period of opening of the injection valves is controlled by a monostable multi-vibrator 25. The period is dependent upon the position of the movable core 39 of a transformer which couples the collector of the output transistor T 2  to the base of the input transistor T 1 . The position of the transformer core 39 is controlled by the pressure in the inlet manifold 12, and each cycle of the multi-vibrator is triggered by the cam 31 rotating with the crank shaft 17 and operating a switch 32 to connect a capacitor 33 to the positive lead 26, the transistor T 1  being rendered non-conductive. The pump 16 is driven by the crank-shaft 17 or an electric motor.
