Title: Improvements in or relating to inertia-operable electric switches
IPC: H01H35/14
Filed: 1948-10-06
Abstract: 649,415. Inertia switches. MACDONALD, I. G. Oct. 6, 1948, No. 26091. [Class 38(v)] A switch suitable for operating fireextinguishing apparatus in an aircraft in the event of a crash, comprises a cylindrical mass 1 centrally located in a housing 2 by an annular spring 3, having elliptical coils 4, and supported for horizontal movement by ball bearings 13. A spring-plunger 14 engages, by a ball-bearing 15, a recess 16 in the mass 1 whereby on displacement of the mass due to deceleration of the craft, the plunger 14 is raised to operate the plunger 22 of a micro-switch 35. The switch is reset by the spring 3 and plunger 14 and may therefore be hermetically sealed. A stop 23 engaging a flange 32 on the mass 1 limits the angular range in which the switch is responsive to 90 degrees on each side of the longitudinal axis of the craft. In a belly landing when the mass 1 may not be affected by deceleration, an eccentric plunger 26 in contact with the under surface skin of the craft breaks or deforms a disc 30 and, by engaging the side of a recess 27 in the bottom of the mass 1, moves the latter and operates the switch 35. In a modification the spring 3 may be replaced by an annular spring snugly fitting the housing 2 and having inclined coils or by a series of radially disposed compression springs; and further, movement of the mass 1 may be more restricted by further stops 23 or by a ring engaging a flange 33 on the mass. An arrangement for a twinengined aircraft embodying three switches each having an angular range of 90 degrees, is described. According to the Provisional Specification, the plunger 14 operates the switch 35 through a lever and the plunger 26 is actuated by a lever housed in a blister beneath the craft.

Abstract: 946,482. Illuminated signs. CLAUDGEN Ltd. July 2, 1962 [ July 19,1961], No. 26155/61. Heading G5C. In an advertising sign of the type in which light from a source is transmitted through a display screen which is at least partly lighttransmissive, the screen is formed at least partly by an opaque panel an area of which contains a multiplicity of closely spaced apertures, and on the side of the panel away from the source the boundaries of the apertures are light reflective and are inclined to the face of the panel. Figs. 1 and 2 show an advertising sign in which a sheet metal trough has the shape of letter N and houses a mounting for an elongated N shaped low pressure tubular electric discharge tube 2. A sheet 4 of translucent plastic closes the mouth of the trough and a sheet of slotted expanded aluminium, Fig. 3, (not shown) is painted on both sides with gold paint and housed behind a further N shaped sheet 7 of plastic material e.g. methyl methacrylate, the whole being sealed by strips 8 of coloured adhesive tape. The webs of metal between the apertures in the expanded metal sheet 6 are inclined to form internal and external reflectors and may form a decorative pattern as shown in Fig.4 and render the sign decorative by external light falling on it when the lamp 2 is extinguished.

Title: Improvements in and relating to purification of sodium carbonate containing materials
Inventor: ROBERTS CHARLES PLEASANT
IPC: C01D7/26
Filed: 1962-07-07
Abstract: Substantially iron-free crystalline sodium-carbonate-containing crystals, i.e. crystals containing a sodium ion and a carbonate or bicarbonate ion, are prepared by dissolving crude trona mineral in a recirculating sodium-carbonate-containing mother liquor, from which sodium - carbonate - containing crystals have been separated, carrying sufficient sulphide ion dissolved therein to substantially depress the iron solubility in said recirculating mother liquor, separating insolubles from said solution, crystallizing sodium - carbonate - containing crystals from said solution while volatilizing sulphide therefrom to increase the iron solubility in said solution, separating the crystals from said solution, adding make-up water to the mother liquor, returning the mother liquid to dissolve more crude trona, and adding sufficient sulphide ion to said recirculating mother liquor to maintain the sulphide ion concentration therein from 100 to 1000 p.p.m.  The addition of sulphide to the recirculating mother liquor may take place prior to the addition of the crude trona. During volatilization, the sulphide ion concentration may be reduced to between 100 and 200 p.p.m.  Soda-ash, having an iron content of 30 p.p.m. or less, may be produced by calcining the sodium-carbonate-containing crystals obtained.

Title: Improvements in or relating to circuits for stabilizing the speed of direct-current motors
IPC: H02P7/26
Filed: 1951-11-09
Abstract: 696,462. Automatic speed control. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Nov. 9, 1951 [Nov. 14, 1950], No. 26278/51. Drawings to Specification. Class 38 (iv). The invention relates to automatic speed control of a D.C. motor supplied by a gridcontrolled rectifier wherein speed adjustment depends on the difference between a reference voltage and the back E.M.F. of the armature, the latter being derived from the armature voltage and a component proportional to the armature current. Owing to the form factor of the current, the compensation varies with the load on the motor, and causes a speed variation. To overcome this variation, according to the invention a voltage proportional to the armature current is injected in series with the reference voltage. In Fig. 1 (not shown) the compensating voltage opposes the reference voltage, but with some motors it may be required to assist the reference voltage, Fig. 2 (not shown).

In a spreader stoker for a furnace the fuel is fed from a hopper 56 on to a conveyer comprising a pair of endless chains between which there are secured transverse members 10 which drag the fuel along a platform 34 from the end of which it falls to a plate 40, the return run of the transverse members then propelling it along the plate 40 over the forward edge of which the fuel falls on to a bladed rotary projector 68 for projection into the furnace. A steady discharge of fuel over the edge of plate 40 is ensured by constructing the transverse members 10, Fig. 2, of either cranked form, as shown, or of inclined or V-form. The position of the forward edge of plate 40 is adjustable by screw-and-nut mechanism 50 which can be operated to slide the plate 40 longitudinally over a nest plate 48. A grating comprising a plurality of vertically arranged side-by-side plates 80 extends between the forward edge of plate 40 and the projector to allow air to be blown into the furnace.
