Title: Improvements in or relating to electric switchgear, motor starters, contactors and the like
IPC: H02B13/02
Filed: 1951-09-14
Abstract: 707,423. Switch bases and covers; controllers. BROOKHIRST SWITCHGEAR Ltd., and MORREY, C. Aug. 19, 1952 [Sept. 14, 1951], No. 21592/51. Classes 38(3) and 38(5) In order to isolate a motor starter, contactor or other switchgear from the supply when the lid of the casing containing it is opened, the contactor &c. is mounted on a panel 13 which is moved outwards into the position of Fig. 2, when the lid is opened, by a spring 17a thereby separating contacts 14, 16. In this position, further outward movement of the panel is prevented by a lug 22 on a blade spring 20 engaging a lug 18 on the panel and inward movement is prevented by the lug 18 having snapped into the forked end of a second blade spring 21. If it is desired to remove the panel completely the spring 20 may be pushed back by hand and the panel, which pivots loosely about its lower end, lifted out. When the lid is closed a projecting arm on it engages and presses back the bevelled end of the spring 21 releasing the panel from the springs 20, 21. The panel 13 may then be moved into the " on " or " off " position by operation of a lever on the lid, the inner cam shaped end of the lever engaging a part 27 of the contactor.

Title: Improvements in or relating to liquid heating systems deriving heat from internal combustion engines
IPC: F02N19/10
Filed: 1950-09-12
Abstract: 674,510. Heating by circulation of fluids. ELDERTON, A. J. Oct. 16, 1950 [Sept. 12, 1950], No. 22393/50. Class 64(ii) In a system, e.g. for space heating or process work heating, a liquid such as water is heated by flowing in series through the cooling jackets of the cylinders of a reciprocating or of a turbine I.C. engine A and an exhaust gas heat exchanger C. Moreover, a thermostat P at the watetr outlet of the heater C controls a three-way diverter valve Q which apportions the water flow between the heater C, which may be of the kind described in Specification 550,475, and a byepass R to maintain the temperature at this water outlet. The three-way valve Q may be replaced by utilising the different resistances to flow in the pipe lines and having a simple valve in the line of least resistance. From the radiators or heat exchanger comprising the heat dissipating system E and from the byepass R, the water is drawn by a pump H through a cooler F back to the engine A. The cooler F may be the normal engine cooler alone or with another cooler, e.g. in a unit comprising the two coolers in parallel. A make-up tank F<SP>2</SP> is included in the system. The exhaust gases can be diverted from the waste heat boiler C, if the water is too hot for the utilizers E, by valve O in the exhaust pipe N, which valve is controlled by a thermostat S and may be of the form described in Specification 535,163, [Group XXIX]. To maintain a desired temperature of the water returned to the engine jackets, a thermostas V causes the actuation of a valve U controlling the flow of hot water from the heater C through a pipe W byepassing the heat utilizers E and cooler F. If the returning water is too hot the byepass W is colsed and the flow of coolant, e.g. water, from a tank J by way of a pipe K through the cooler F is increased by a thermostat S<SP>2</SP> actuating a byepass valve T or a pump M in the coolant circuit. If the water returned from the heat utilizers E is at a suitable temperature for the engine cooling, the byepass W is closed by the valve U and the coolant pump M is stopped or the byepass for the coolant opened by the valve T. In a modification, Fig. 2 (not shown), in place of tthe cooler F, a fancooled radiator cools the return water, a thermostat at the engine water inlet actuating a three-way valve, controlling the relative flow of water through the radiator and a byepass, or actuating the fan starter. The valves may be operated by electric motor. The Provisional Specification describes also the cooling of the water returned to the engine in a cooler other than the normal cooler for the engine, and the heating of this returned water, if required, by a fuel-fired heat exchanger.

Title: Magnetic-film stripe domain diffraction-grating
IPC: G02F1/09
Filed: 1971-04-19
Abstract: 1342834 Deflecting light SPERRY RAND CORP 19 April 1971 [24 Feb 1970] 22506/71 Heading H4F [Also in Divisions G2 and H1] In a light deflector, parallel magnetic stripe domains capable of providing a variable diffraction grating are produced in a film, e.g. of ferrous alloy, Ni, MnBi, YIG, GdIG, RbNiF 3 , chromium trihalides, EuO, EuSe, by applying thereto and in the plane of the film mutually orthogonal A.C. and D.C. magnetic fields, the direction of the strips being parallel to the D.C. field direction and their width being a function of the D.C. field amplitude and polarity. The A.C. field serves to facilitate the response of the domains to change in the D.C. field by reducing their effective coercivity. As described, the grating is formed (a) by having a Bitter snspension of magnetic particles adjacent the film to align with the strips for a transmission grating; (b) if the film exhibits the Kerr magnetooptic effect, it behaves as a reflection grating to plane polarized light; (c) the film or a coating thereon may exhibit the Faraday effect. Depending on whether one surface of the grating is coated with a reflective metal film (for example the magnetic film itself, if coated with a Faraday effect coating) it will act as a transmission or reflection grating towards polarized light, for example from a He-Ne laser. The D.C. and A.C. fields may be provided by respective pairs of coils mounted on a yoke rotatable about an axis normal to the plane of the film, Fig. 11 (not shown), i.e. to vary the direction of the diffraction grating. In a modification, Fig. 14 (not shown), two pairs of coils apply an A.C. field in the film plane and a variable D.C. field perpendicular to the film. A further coil applies a D.C. field in the film plane and is rotatable (over a limited angle wherein it may still be considered substantially orthogonal to the A.C. field) with respect to the film and the A.C. field, to vary the direction of the stripe domains. The domain width is a function of the perpendicular D.C. field strength. In alternative forms of device, each field may be varied electrically, by adjusting the size and magnitude of two orthogonal components, instead of by mechanical rotation, to vary the stripe domain direction. For the reflection gratings, the field is most easily supplied by strip conductors behind the film. A Kerr reflection grating may replace a laser mirror, or a Faraday Effect transmission grating may be placed between laser mirrors to provide a laser output beam in a controlled direction.
