Title: Electrical switches
IPC: H01H43/28
Filed: 1975-09-19
Abstract: 1514937 Time-delay switch RANSOME HOFFMANN POLLARD Ltd 19 Sept 1975 [19 Sept 1974] 40928/74 Heading H1N A pneumatic time-delay switching mechanism can be selectively operated, in response to an actuating signal, in either of two modes, viz. (1) to switch-over after a predetermined delay period, or (2) to switch-over immediately and then switch back after the delay period when the actuating signal is removed. The delay is effected by a spring-loaded bellows 132 adjusted by altering the effective length of an air inlet groove in a dial 158. Bellows expansion transmits motion to a snap-action change-over switch 104 via a lost-motion linkage 106. Switch operation is either by a push-button 42 or an electromagnetically operated armature 60, either of these actuating a rod 36 to effect pivoting of an arm 182 via a lever assembly 174 (Figs. 5-7, not shown). A "mode-shift" arm 176 moves the lever assembly axially to determine whether the pneumatic delay will be effective upon actuation of the rod 36 or after its release.

Title: Radar apparatus
IPC: G01S13/526
Filed: 1970-08-29
Abstract: 1362785 Pulse radar EMI Ltd 27 Aug 1971 [29 Aug 1970] 41676/70 Heading H4D An MT1 apparatus includes means for comparing at least two successive echoes from a given range, means for multiplying at least one echo by a plurality of sets of weighting coefficients, each representing a particular clutter velocity, to provide a plurality of compared signals and means for selecting therefrom the set of coefficients which best represents the actual clutter velocity at that range. The Fig. 1 embodiment shows a two-pulse canceller incorporating quadrature detection and a network including resistors 9a, 10a representing cos # and sin # and providing outputs from adders 6a, 6b representing sin #-cos # sin (# + #) + sin # cos (# + #) and cos #-sin # sin (# + #)- cos (# + #) + (1-cos#)cos(# + #) respectively where cos 0 and sin 0 represent the quadrature components of the echo from a first pulse and # represents the phase error due to a clutter velocity V, where # = 4##T/#. The residual output from deresolver 13 is used to control servo-mechanisms operating resistors 9a, 10a to provide a minimum residue. In an alternative embodiment suitable for large scale integration, 2N + 1 channels are provided each for a different value of # (Fig. 2, not shown). A scanning unit detects the channel having the minimum integrated residue and gates that channel to the system output on the next pulse. This system may be used to provide clutter improvements at all ranges by providing sufficient memory capacity to store the particular value of # for each range interval. Also described is a similar three pulse canceller using staggered p.r.f. (Fig. 3, not shown). For systems using multi-pulse staggered p.r.f. cycles a heavily increased number of channels is needed to take account of the changing pulse-to-pulse interval pattern. In this case only three values of # are used viz. minimum, maximum and zero. From the results obtained at these values, an interpolated value is determined and used in a fourth channel (Fig. 4, not shown). Figs. 5, 6 (not shown) illustrate networks for providing the interpolation using a parabolic clutter residue function. When the clutter velocity induces a phase error representing a substantial fraction of the p.r.f. the normal scanning unit also provides the value of # to a register (54, Fig. 9, not shown) which updates a phase angle used to adjust the phase of the input to the comparing unit, thereby reducing the value of #.

A copper-clad aluminium rod is made by forming a composite billet comprising an aluminium core and a copper sheath and coldextruding the billet. The sheath may be a tube (4), Fig. 1 (not shown), which is a close fit over the core (1) and the mating surfaces are machined and chemically or mechanically cleaned before assembly. The ends of the tube tightly engage the core to seal it or alternatively the tube is sealed by elastomeric rings or plastics sealing compound. The internal surface of the tube may be purged with nitrogen during cleaning and assembling or the cleaning performed in nitrogen or under vacuum. To effect a sound metallurgical bond between the core and the tube the reduction should be at least 70%. The composite billet may alternatively be made by electroplating the core with copper. The surface of the core may be first coated with zinc or a copper-based tin alloy (15), Fig. 2 (not shown). The composite billet has a tapered forward end (2), Fig. 1 (not shown), and a short cylindrical nose portion (3).

Abstract: 906,426. Valves. CARLSTEDT, S. B. F. Dec. 31, 1958, No. 42174/58. Class 135. A reversible electric motor 38 drives a regulating valve 16 through a centrifugal clutch 46, 48, 50, a reduction gear train 42 and a screwed nut 28. A disc 24 is fixed to the valve stem 20 and a pin 32 is screwed into a selected peripheral hole 36 of said disc and passes through a slot 34 in the cover 30 so preventing rotation of the valve member. The direction of rotation of the motor is determined by the position of a single pole double throw switch which may be controlled by temperature responsive means. The centrifugal clutch ensures that the drive is transmitted to the valve member only when the motor reaches a predetermined speed.

With a fluid-control valve in the position shown an outlet chamber 19 is connected to atmosphere via a passage 15 through a spring- loaded closure member 5. Upon admitting fluid-pressure in a control chamber 8 attaining a given value it depresses a diaphragm 7 and an element 14 against a spring 12 until the latter abuts the closure 5 and interrupts the connection of chamber 19 to atmosphere. Further motion of the element 14 commences to unseat the closure 5, which action is aided by the pressure in an inlet chamber 18 acting on a diaphragm 6 that supports the closure 5 whereby the latter is opened rapidly. The effective areas of parts 7, 14, 5 and 6 are of an ascending order. The control chamber 8 may be dispensed with and the element 14 is moved by a manually or automatically actuated eccentric.

A system for measuring the vertical component of gravity comprises two masses 1, 2 carried substantially in vertical alignment by double-armed pendulums 3, 4 pivotally supported by horizontal torsion wires 6, 7 and the lower mass 1 joined by a wire 5 to the end of the pendulum 4 opposed to the mass 2. The pendulums 3, 4 have lateral projections 9, 8 to which the wires 6, 7 are secured and the outer ends of the wires 6, 7 are secured to frames 10, 12 connected to stationary parts by springs. The frame 12 is supported by horizontal torsion wires at right-angles to the pivotal axis of the pendulum 4 whose angle of inclination can be adjusted by adjusting the tension of the spring 14. The frame 10 is supported by torsion wires 11 co-axial with wires 6 but of higher torsional resistance. An optical system including lens 17, mirror 18, a light-source and pendulum extension 15 enable measurements to be read at a distance when the system is stationary. When the system is on a moving vehicle an electrical feedback measuring system is used and a similar system is used to compensate for the differential effect on the two masses of any horizontal acceleration.
