Abstract: 745.514. Control of D C. motors: controllers. BRITISH THOMSON-HOUSTON CO.. Ltd. March 18, 1953 [May 7. 1952], No. 11534/52. Drawings to Specification. Class 38(3) Relates to a Ward Leonard drive for a winding engine in which a cam system driven from a winding drum has cam rockers coupled to potentiometer rheostats so that when the load approaches the limits of its travel a rheostat is moved towards the neutral position to bring the engine to rest without excessive acceleration or retardation currents being generated. A lost-motion coupling between the winding drum and cam system ensures that the adjustment of a potentiometer rheostat is only effected during a predetermined limited travel of the load. The lost-motion coupling arrangement is shown as consisting of a plurality of coaxial discs disposed side-by-side on a shaft. the first and last discs being connected respectively to the winding drum and to the cam system while the intermediate discs are free to rotate on the shaft. Rotatoin is transmitted between discs by pins which engage only within a limited relative angular position of adjacent discs. When pins on all the discs are in engagement the drive to the cam system becomes positive. The amount of lostmotion may be adjusted by pre-setting the position of one of the discs. The cams may be provided with bias weights. Specifications 620,236 and 704,873 are referred to.

Title: Improvements in control valve devices for connecting two or more hydraulic actuators to a common continuous feed
IPC: F15B13/08
Filed: 1957-04-11
Abstract: 801,915. Control valves. GRATZMULLER, J. L. April 11, 1957 [April 11, 1956], No. 11855/57. Class 69 (2). A control valve device for selectively connecting each of two service lines 6, 7 either to an input duct 24 or to exhaust, comprises two two-position valves 4, 5 and a duct 25 connecting service line 7 to the duct 24. When there is no liquid in the system, plungers 10 in valves 4, 5 rest on balls 14 without displacing them. If liquid is introduced to duct 24, pressure forces valve 26 to allow fluid to flow via duct 25 and port 11 to bore 9 of valve 5. The fluid forces plunger 10 up and flows via openings 18, 19 to the reservoir 2. If plunger 12 in valve 5 is now depressed, ports 18 are blocked, ball valve 14 is unseated and duct 7 is fed from duct 24. If, instead, plunger 12 in valve 4 is depressed, ball valve 14 in valve 4 is unseated, allowing liquid to enter duct 6. If both plungers 8 are depressed, both ducts 6, 7 are fed. In the second and third cases, the pressure in ducts 24, 6 then being equal, spring 30 moves valve 26 to block duct 25. In another embodiment, there are more than two service lines each controlled by a valve like valves 4, 5.

Abstract: 835,933. Electric measuring systems. COAL INDUSTRY (PATENTS) Ltd. April 11; 1958 [April 11, 1957], No. 11881/57. Addition to 756,662. Class 40 (1). [Also in Group XL (c)] The apparatus for the determination of the percentage carbon monoxide in an atmosphere described in the parent Specification by measuring the temperature difference between two: thermistors each in the atmosphere, one of the thermistors being also located in contact with an oxidizer, the teinperature difference being determined by measuring the change in resistance, is modified by using transistors instead of thermionic valves in the electrical circuits, with additional ambient temperature compensation. As shown, a transistor oscillator T1 has a large degree of negative feed-back between base and emitter, and positive feed-back via a transformer TT1 sufficient to saturate the transistor on the negative swing and to cut it off on the positive swing, to produce a rectangular output voltage between zero and a maximum value determined by emitter resistors R4, R5, R6 selected by switch SW1a, and adjusted by potentiometer VR1. The. oscillator feeds through a buffer stage T2 to a bridge incorporating the measuring thermistors 4, 5. The bridge unbalance voltage is amplified by transistors T3, T4, whose gain is adjusted by potentiometers VR2, VR3 to differ from optimum in a sense to compensate for variation in sensitivity with temperature, and rectified at MR, to be shown on a meter M1, and to control an audible alarm PH and visual alarm WL via relay winding RL.

Title: Improvements in processes for immunising or preserving seeds, grain or the like, andin the products treated
Filed: 1943-07-23
Abstract: Grain, peas, beans, cocoa beans, nuts, sago and similar products are protected from insect pests by admixing therewith small quantities, which may be much less than 1 per cent. of finely crystalline and freely flowing g -alumina of low bulk density.  The g -alumina may be obtained by igniting crystals of ammonium alum, or aluminium sulphate with or without ammonium sulphate and water, in such a way as to produce a mass of the character of a meringue at temperatures below those at which a -alumina is formed, and breaking up the mass by a tumbling process preferably without grinding, for example in a rotary cylinder closed at one end or both ends by a fine screen of woven silk.  The powder passing through the silk will have the necessary free flowing characteristics.  It is stated that dry grinding with the use of pebbles and balls will not give the desired product, though grinding in liquids such as ether may do.  The prior use, for preserving grain or seeds, of ground siliceous minerals, silica, mineral phosphate, magnesite, dolomite, diatomaceous earths, and diamond dust, is referred to.

Title: Method of making multicellular thermoset foamed plastic beads
IPC: B29C44/34
Filed: 1972-03-15
Abstract: 1390208 Pelletizing D ROSENTHAL 15 March 1972 12114/72 Heading B5A [Also in Division C3] Multicellular, thermoset, foamed plastics beads are prepared by a process which comprises, generally, suspending liquid droplets of a liquid thermosettable composition containing a blowing agent in the fluid medium, activating the blowing agent before curing of the composition and subsequently separating the plastics beads from the fluid medium (see Division C3), using an apparatus which may be as shown in Figs. 1 and 2. In Fig. 1, the liquid composition is fed into a mixing head 12, out through outlet 14, through a dropletizing mechanism 16 to form liquid droplets which are discharged into a vertical column 24 of a liquid having a specific gravity in excess of the specific gravity of the composition so that the droplets rise through the liquid. As the droplets rise through the liquid, the blowing agent is activated, and by the time the now cellular droplets reach the separating mechanism the composition will have substantially cured. The top of the tube 26 opens into a duct 28 along which the liquid medium containing the plastics beads is circurlated and the beads are separated by lifting them up on to a conveyer 34 and subsequently on to conveyer 42 which leads the beads away for further use. In Fig. 2, the liquid composition from mixing head 46 is formed into droplets by the mechanism 52 in the form of of a rotating cone which flings off the droplets into the path of a gaseous medium at the foot of an expansion chimney 58. The gaseous medium is blown upwards by means of blower 60 and auxiliary blower 62, carrying with it a cloud of droplets which are forming into spheroidal shape and foaming and curing as they ascend. Auxiliary heating means, e.g. radiant heaters 68 may be provided. From the point B the stream of gas enters a separation mechanism constituting a chamber 70. In this chamber the plastics beads are collected in bins 72 and the gaseous medium escapes through vent 74. The beads may be produced from components forming such resins as polyurethanes, epoxy, phenol, formaldehyde, resorcinol formaldehyde, melamine formaldehyde, urea formaldehyde, polyester and polyurea.
