Title: Improvements in or relating to electrical systems, particularly systems for converting direct current into alternating current
IPC: H02M7/62
Filed: 1942-05-20
Abstract: 558,658. Converting. STEVENS, A. H. (Electronic Laboratories, Inc). May 20, 1942, No. 6878. [Class 38 (ii)] In an arrangement whereby D.C from a source 25, 26 is converted into A.C. in a load circuit 16 by means of an intenupter 10 which supplies an intermittent current to the two halves of the centrally-tapped primary of a transformer 11, the intermittent current to each half of the transformer primary proceeds by parallel paths which include the two halves of a centrally tapped balanced inductance such as 43, two contacts such as 19, 21, and a current-diverting impedance such as 37 arranged between the contacts. The arrangement ensures the two or more parallel contacts such as 19, 21 dividing the current equally between them even though one contact should break slightly before the other and yet the resultant inductance of the two halves of the inductance 43 is substantially nil. The impedance 37 may be a resistance, an inductance, or a resistance and inductance in series or parallel and a suitable value for each resistance or inductance is four times the resistance or inductance of the vibratory circuit. In a modification, the vibratory reed 17 moves between four instead of two pairs of contacts ; the additional pairs leading to additional balanced inductances ; and central tappings from all four inductances lead to further balanced inductances connected to the transformer primary.

Title: Improvements in or relating to hydraulic transmission arrangements for self-propelled vehicles
Inventor: COOPER FREDERICK DOUGLAS
IPC: B60K17/10
Filed: 1955-03-10
Abstract: 795,535. Hydraulic transmissions. FORD MOTOR CO., Ltd. March 2, 1956 [March 10, 1955], No. 7034/55. Class 69 (2). [Also in Group XXXI] Flow divider.-Equal volumes of liquid are fed to two motors on the driving wheels of a vehicle by directing the whole output of a pump first to one motor, then to the other, in rapid alternation. On starting from rest, pressure liquid entering a port 7 moves a valve 3 to the left, owing to its spool 4 being of slightly greater diameter than the spool 5. The pressure then acts through a port 9 to move a spool 11 to the right, thereby uncovering a port 15 connected to the pressure supply; liquid flows through passages 21, 22, 23b to an outlet 33 leading to one of the motors. The pressure acts through a passage 20 to move the valve 3 to the right, whereby the spool 11 is moved to the left, causing liquid to be fed to the other motor from the outlet 33<SP>1</SP>. The resulting continuous oscillation of the spool 11 gives a " lockeddifferential " condition of drive. When the direction of flow is reversed to drive the vehicle backwards, exhaust liquid from the motors entering at 33, 33<SP>1</SP> passes through ball valves 24 to a passage 25a leading direct to the pump; during forward running, the valves 24 are kept closed by the supply pressure present in the passage 25a. Steering.-A manually-operated valve 28 has a central spool 28a grooved for nearly its whole length so that a small displacement in either direction from the position shown interconnects the outlets 33, 33<SP>1</SP> to give a " free-differential " condition of drive. Further displacement of the valve causes one or other end spool 28b to restrict (or completely stop) the flow to one outlet (the flow to the other being augmented through the grooves in the spool 28a) to give power-assisted steering of the vehicle; the steering effect also obtains when the vehicle is driven backwards.

Title: Improvements in or relating to the combustion of refuse
IPC: F23G5/00
Filed: 1957-03-05
Abstract: 823,568. Treating refuse. VAGO, P., and VASS, B. March 5, 1957, No. 7229/57. Class 111. [Also in Groups II, XII and XXX]  A process for treating refuse, to render it suitable for use as fuel in a boiler furnace, comprises eliminating pieces of iron from the refuse by magnetic attraction and then effecting a pneumatic separation of combustible from incombustible parts of the refuse simultaneously with a vaporisation of the moisture content of the refuse by means of combustion gases from the boiler furnace, the temperature of the combustion gases applied to the refuse being regulated in such a manner that the heat transmitted to the refuse substantially equals the sum of the heat of vaporisation of the moisture and of the heat required for heating the refuse to about 100‹C., the mixture of combustion gases and vaporised moisture being then allowed to escape into the atmosphere. The desired amount of heat is transmitted to the refuse if the gas-vapour mixture leaving the plant has a temperature of about 110‹C. In the drawings, refuse carried on conveyer belt 9, Fig. 7, passes through magnetic device 19 for removal of iron objects and is then directed by scraper 56 through crusher 20. The crushed refuse falls on to conveyer belt 21 which delivers it on to endless conveying and drying grate 25, Fig. 6, immediately below a similar grate 26. Within grates 25, 26 are airdistributing boxes 27, 28. Box 27 is connected by pipe 29 to the blowing side of blower 30, which draws combustion gases from the combustion zone via pipe 48 and heat exchange 47. Box 28 is connected by pipe 32 to the suction side of blower 31, pipe 32 being provided with a dust separator 42. The heavy incombustible portions of the refuse fall from grate 25 into funnel 43 and are classified according to their specific gravities in hydraulic brake sieve 44. Under the influence of the horizontal stream of gases from blower 31, the lighter combustible portions of the refuse are directed into funnel 43<SP>1</SP> and are thereupon charged to the reciprocating step grate 45 in the combustion zone. Hermetically sealed receptacle 51, within classification chamber 36, is connected by way of pipe 52 to a cylinder containing a piston 54, the cylinder being closed by bellows 53. Receptacle 51, pipe 52 and the cylinder are waterfilled, and piston 54 engages air inlet valve 55. By means of this arrangement, the temperature of the combustion gases utilized for drying the refuse is controlled. The combustion gases, having effected the drying of the incoming refuse, are sucked through conduit 38, Fig. 7, by means of hydraulic exhauster 39 and discharged into the smoke exhaust channel 40, which is connected with a chimney for venting the gases to the atmosphere. Cold water mixed with a soluble disinfectant such as formalin may be introduced into exhauster 39 to disinfect the gases.

Filed: 1942-05-28
Abstract: 556,447. Purifying water. CANDY, F. P. May 28, 1942, No. 7240. [Class 46] In the purification of water, e.g. softening by means of lime or lime and soda or treatment with a coagulant, the water enters the lower part of a tank 1 through one or more movable arms 2 in such manner and with such velocity as to keep the water in that part of the tank in continuous agitation and thereby maintain a suspension of solid matter through which the water passes. The solid matter is generally derived from the water but finely-divided chalky or siliceous material may be used, particularly at starting. As shown, the arm 2, a counterbalancing arm 3 and a pipe 5, to which the water is supplied by a pipe 7, are secured to a rotatable shaft 10 and are rotated by the water issuing from the outlets 4 or by an electric motor geared to the shaft. Turbulent agitation in the soil 14 maintains a suspension of solids in the zone 15, baffles or deflection being provided, if necessary. Reagents may be added in the pipe 5 or the lower part of the tank. The tank may increase in diameter towards the top. The arms may be given a reciprocating, instead of a rotary, movement. The pipe 5 may be connected with the pipe 7 and a joint provided between it and the arms. Means may be provided for withdrawing of solids from the top of the suspended bed and from the bottom of the tanks. Two treating compartments may be provided at the inlet end of an oblong tank. Specification 545,913 is referred to.

Abstract: 994,852. Laminates and laminating. GARLOCK Inc. Feb. 25, 1963 [March 5, 1962], No. 7529/63. Drawings to Specification. Heading B5N. [Also in Division H1] Printed circuit assemblies are made from flexible laminated sheets comprising at least one sheet of electrodeposited unoxidized copper directly bonded to the surface of a flexible base of a copolymer of from 5-50% by weight of hexafluoropropylene and from 95-50% by weight of tetrafluoroethylene using heat and pressure. The circuit may be formed by etching unwanted portions of the copper to form a predetermined conductive path, a further layer of the same copolymer being placed over the copper sheet and pressure being applied to cause it to flow into exposed areas of the base and unite therewith. A sheet of the copolymer may be drawn from a roll, pre-heated in a heating tunnel, and passed between a pair of rolls together with a sheet of unoxidized electrodeposited copper with the grainy side of the copper in contact with the copolymer sheet. The roll in contact with the copolymer is heated either by gas or electrically, to melt the resin surface, sufficient pressure being exerted to effect bonding with the copper. The roll in contact with the copper may be either hot or cold. The laminate so formed is then passed between two sets of water-cooled rollers to cool it in two stages. A further sheet of copolymer resin is subsequently bonded to the exposed areas of the first sheet to completely enclose the copper. Alternatively a platen press may be used using a release foil to prevent adherence between the resin sheet and the platen, the copper sheet being pressed on to the resin sheet and baked; it is then etched and a further resin copolymer layer is applied. The Specification includes information relating to the properties of the resin copolymer.
