Title: Improvements in or relating to electrical signalling apparatus
Inventor: THOMPSON GEORGE WILLIAM
IPC: G07C1/20
Filed: 1960-03-15
Abstract: 974,083. Electric selective signalling; checking attendants. AUTOMATIC TELEPHONE & ELECTRIC CO. Ltd. April 11, 1961 [March 15, 1960], No 9027/60 Headings G4H and G4T. In an electrical identification signalling system, a dial switch which is provided with coding means, causes, in response to a prescribed manual operation, transmission over a first signalling wire of a first predetermined series of impulses irrespective of the identity and, over a second wire, a second predetermined series of impulses variably spaced in dependence upon the identity to be transmitted, the relationship between the two series identifying the caller. As applied to a toll booth system, the identity and the starting and finishing times of an attendant or maintenance officer on duty at a toll booth are signalled to a central control station. Fig. 2 is an exploded view, and Fig. 3 a cross-section of the dial switch. A rotatable finger plate 11 has a finger hold 12 and a socket 26, the wall of which is formed with twelve identical longitudinal grooves 27 and a wider and deeper groove 28; the inner ends of twelve spring-loaded plungers 32, protruding into respective grooves 27, and a similar plunger 33 protrudes into groove 28. Each attendant is provided with a code plug 13, the barrel 29 of which is formed with six longitudinal splines 30 in positions appropriate to a six-out-of-twelve identification code allocated to each attendant, Each plug 13 can only be inserted into the socket 26 in one way, and when inserted the six splines 30 move six corresponding plungers 32 radially outwards to protrude beyond the finger plate 11 and thereby control a pair of contacts for the generation of identification signals. When an attendant goes on duty, he retracts a spring- urged slidable member 17, inserts his coding plug 13, releases member 17, and winds up the dial. When the dial is released signals are transmitted to the central station over two wires twelve uniformly-spaced pulses on a timing wire, and six pulses, occurring at times determined by the coding plug and identifying the attendant, on a code wire. At the end of the transmission of the finger plate 11 is arrested by engagement of a stop 38 with a projecting tongue under the member 17, whereby a circuit is maintained over the timing wire until such time as the attendant, at the end of his duty period, retracts member 17 to remove the coding plug 13, thus fully releasing the dial switch and opening the circuit. A coding plug, 14, Fig. 2, for a maintenance officer has an extra spline 31 which lifts a special plunger 33 to release a key 22 providing access to the relevant portion of the register equipment. This action automatically operates an indicator showing that the toll-collecting lane is closed.

Abstract: 1,024,050. Valves. BRITISH THERMOSTAT CO. Ltd. Feb. 25, 1965 [March 4, 1964], No. 9145/64. Heading F2V. A three-position operating stem 1 controls a rotary-disc valve 3 and the setting of a thermally-responsive valve 32 actuated by a bellows 33; in the " off " position the stem is prevented from moving by a pin held between two projections in the cover 4. Upon depressing the stem, turning it anti-clockwise and then releasing it the stem occupies the second position in which the disc valve connects a gas supply with a first main-burner via a first outlet; the axial stem movement actuates a pilot valve 20 in the supply to a pilot burner, and an electric switch in the pilot burner igniter circuit. In this position the pin is held between cover projections. When the stem is again depressed and rotated clear of the projection, the igniter and pilot burner are again operated and the stem may be rotated up to a projection 15. In this third position the supply is connected to the first and a second outlet 39; the thermally responsive valve 32 is in the flow path to the outlet 39. The pilot valve is actuated by a disc 7 on the stem via a lever 17 which disc also operates the electric switch. The thermally responsive valve 32 is acted upon by a spring 31, the loading of which is varied by rotation of the disc valve 8 through the squared end of a range spindle 29 that co-operates with a splined plate 28 in the valve 8.

Abstract: 1376095 Distributing forage P DENIS 26 Feb 1973 [29 Feb 1972] 9219/73 Heading AIM [Also in Division A4] In a rotary brush for use in cattle forage distribution machines, the bristles are maintained at the same angle to the swept surface throughout brush rotation by providing circular flanges 6 at each end of a rotatably driven shaft 4 and pivotally connecting a series of brush elements 7 between the flanges for rotation about axes parallel to the longitudinal axis of the shaft and spaced about a circle centred on the longitudinal axis. In order to simultaneously adjust the angle of inclination of the bristles of all the elements 7 relative to the swept surface, each brush element has the pivot at one end thereof extending through the circular flange and connected to an arm 9 rigid with a pin 10 freely rotatable in a rotatable annular member 12, the pins 10 being positioned on a circle of the same radius as that of the circle formed by the axes of the elements but eccentric to the axes of the elements such that rotation of the annular member about an eccentric hub causes adjustment of the pins 10 with rotation of the brush elements to alter the inclination of the bristles relative to the swept surface. The brush shaft may be rotatably mounted between the two arms of a fork pivotally mounted about a vertical axis z-z above an endless belt conveyor 1 supplying forage or other material to the brush such that the brush distributes the forage on one or the other side of the conveyor depending upon its angular position relative to the conveyor. The brush shaft may be driven through a pulley and belt drive from the motion of the conveyor.

Title: Improvements relating to polymeric reaction products of aluminium alkoxides
IPC: C08G79/10
Filed: 1959-03-19
Abstract: Water vapour is introduced into and heated with an aluminium alkoxide in liquid or vapour phase until about two mols of alcohol per mol of alkoxide have been removed to form a polycondensate. Preferred alkoxides are of ethyl, isopropyl, furfuryl or allyl alcohol.  A solvent for the alkoxide, e.g. toluene, xylene or an alcohol of up to 5 carbon atoms is preferably present.  Solvents for the polymer which may be used are hydrocarbons boiling above 140 DEG C., e.g. mineral spirits or mineral oil.  The alcohol solvent may be introduced with the water by adding alcohol to the water used for producing water vapour.  The water vapour may be introduced in a stream of inert gas, e.g. nitrogen.  The reaction may be started under refluxed and continued after all the water has been introduced under vacuum, if desired in a dough-mixer or heated roll.  Polymers produced in mineral oil are useful for forming greases by reacting with a fatty acid, e.g. stearic acid in presence of benzoic acid.  The polymers may be reacted with hydroxy compounds, e.g. higher alcohols, phenols, cyclohexanol, glycols, or hexanediol, or with acids, e.g. acetic, octoic, methacrylic, benzoic, oleic, stearic, furoic, dodecyl benzene sulphonic, or benzene phosphonic acid or with dialkyl hydrogen phosphate.  Acid anhydrides, e.g. phthalic, maleic or dodecyl succinic may also be reacted with the polymers to produce resins compatible with nitrocellulose.  In Examples (1) Vapours of isopropanol and water are led into a solution of aluminium isopropoxide in isopropanol and heated to produce an infusible resin; (2) Superheated water and ethanol vapours are led into a toluene solution of aluminium ethoxide.  Heating liberates ethanol and forms an ethoxy aluminium oxide polymer; (3) Superheated steam is heated with aluminium isopropoxide vapour to produce an isopropoxy aluminium oxide polymer; (4) Vapours of water and isopropanol are introduced into a heated mineral oil solution of aluminium isopropoxide.  A solid polymer containing mineral spirits is produced.  Evaporation of the mineral spirits leaves a powdered polymer which treated with acetic acid in isopropanol solution yields polymeric aluminium oxide acetate.ALSO:Polymeric aluminium alkoxides produced in the presence of mineral oils are reacted with long chain fatty acids, e.g. stearic acid in presence of benzoic acid to produce greases with high dropping points.
