Title: Polyphase current collecting system for a vehicle moving along a trackway
IPC: B60M1/34
Filed: 1972-01-17
Abstract: 1350557 Polyphase current collecting device MERLIN GERIN 17 Jan 1972 [22 Jan 1971] 2066/72 Heading B7L A polyphase current collecting device for a vehicle 10 moving along a trackway comprises three cylindrical phase conductor rails 14, 16, 18, three collector heads 26 each comprising a central member 33 and three peripheral contact shoes 28, 30, 32 biased by springs 34 against the inner surface of the conductor rails, and a comb-shaped connecting member 36 whose teeth 38, 40, 42 traverse longitudinal slits 22 in the base of the conductor rails and are connected to the central members 33 of the heads 26 to pull the latter along the rails. Each head 26 is attached to the corresponding tooth 38, 40, 42 by a rod extending axially of the conductor rail and passing through an opening in the end of the tooth which allows some play to terminate in a stop connected to the tooth through a spring. The conductor rails are mounted insupportarms 56 spaced along the rails and the rails shown at 14, 18 comprise outer tubes 20 of aluminium lined with stainless steel shells 24. An alternative rail shown at 16 comprises an aluminium tube having three strips 58, 58<SP>1</SP>, 58<SP>11</SP> presenting dihedral surfaces to engage mating surfaces on the shoes, and a rib 50 prevents angular motion of the rail. If the rails are arranged vertically the slits 22 are directed obliquely downwardly. The device is stated to be suitable for a vehicle supported by fluid cushions and powered by a linear induction motor.

Abstract: 580,856. Luminescent materials. STANDARD TELEPHONES & CABLES, Ltd. Feb. 4, 1944, No. 2136. Convention date, Feb. 10, 1943. Drawings to Specification. [Class 39 (i)] A process of forming two superposed coatings of luminescent material on the screen of a cathode-ray tube comprises first applying a luminescent powder to the screen as a suspension in a medium consisting of a solution in a first solvent of a first binder, that is an organic solid capable of being driven off by heating in air at a temperature at which no damage to the characteristics of the luminescent powder takes place, to an extent sufficient to remove any constituents damaging to the luminescent quality of said powder, evaporating the solvent and then applying a second luminescent powder as a suspension in a medium consisting of a solution in a second solvent of a second binder, heating to evaporate the second solvent, and finally heating to remove the first and second binders. The first solvent mav be a mixture of acetic acid ester, a ketone and an alcohol and the first binder may be nitrocellulose. The second solvent may be toluene and the second binder ethoxycellulose.

Title: Improvements in or relating to windscreen wipers
IPC: B60S1/44
Filed: 1945-01-29
Abstract: 590,212. Windscreen wipers. FAIREY AVIATION CO., Ltd., GOTT, G. E., and HODSON, C. F. Jan. 29, 1945, No. 2263. [Class 138 (i)] A windscreen wiper comprises wiping arms revoluble in the plane of the screen about a spindle and shaped so that at least the greater part of their lengths form pockets having surfaces presented successively to an airflow which is substantially parallel to the surface of the screen. Two arcuate arms 15, 16, Fig. 1, of resilient metal and having rubber inserts are mounted in the head 12 of a mounting tube 10 and rotated by the airflow parallel to the windscreen 11. The wind pressure tends to lengthen the arm presenting the concave side to the wind, and to shorten the other arm, causing rotation of the wiper due to inequality of the moments on either side of the axis. In a modification, Fig. 3, the arms comprise rigid portions 18, 19 to which are attached extension pieces 20, 21 influenced by springs 22, 23, the action being similar. In both forms, as the speed of rotation increases, the arms tend to straighten by centrifugal force, and the difference between the air pressures on the arms decreases, thereby limiting the speed of rotation. De-icing fluid may be supplied through the tube 10 and an orifice in the head 12.

Abstract: 120,496. Parodi, A., and Borello, J. Feb. 8, 1918. Fire-proof ourtains.-A metallic curtain comprises a number of metal sheets raised and lowered in a telescopic manner, means being provided for automatically counterbalancing t h e sheets, whatever the number at any moment being raised or lowered. The curtain comprises sheets 1, 2, 3, 4, 5 sliding in slots 6, the curtain being raised and lowered by ropes 10 connected to levers 9 pivoted on the lowest sheet 5. The levers 9 hold normally out of action spring catches 8 adapted to engage with holes 7 in one of the slots 6 when the ropes 10 break. The ropes 10 pass around winding- drums 11 rotated by worm and bevel gearing from a shaft 18, which may be turned from either end. One rope 10 is connected to a counterbalancing-platform 20, 21, upon which weights 22 - - 25 are adapted to be loaded and unloaded automatically as the curtain rises and falls, When the curtain is lowered, the weights are carried on a standard 26 by means of brackets 27 - - 30, support levers 31 - - 34, and guiding-levers 35 - - 38. Each lever 35 - - 38 carries a pivoted projection 39 adapted to engage a recess in a weight end. A roller 40 on the platform 20, 21 strikes each lever 31 - - 35 in succession during falling au:l rising so that a weight is deposited on or removed from the platform each time a sheet is added to or removed from the weight to be moved by the rope 10.

Abstract: 327,486. Robertson, H. M. Jan. 23, 1929. Tunnel furnaces. - A furnace for the heat treatment of metal articles, and for baking clay goods and enamelled ware comprises side combustion chambers 8 communicating with a common flue 8<a> abcve the roof 91 of the heating chamber. The furnace shown comprises entrance, heating and cooling chambers 3, 7 and 4 respectively, through which the goods are moved by an endless conveyer 6 having its return lap in a tunnel 5 beneath the furnace. The heating chamber is formed between side walls 9 spaced from the outer walls 10 to provide combustion spaces 8, into which gas or oil is delivered by end burners 19, combustion being effected with hot air from a conduit 19<1> extending beneath the space 8, and separated from it by a heat-conducting partition 20. The spaces 8 are covered by slabs 10<1>, and at the end remote from the burners these slabs are formed with ports leading to a flue chamber 8<a> extending above the heating-chamber 7 and both combustion spaces. The gases are exhausted from the chamber 8<a> at the burner end of the furnace. The roof of the cooling chamber consists of a box through which air is drawn by a fan. In a modification the cooling-chamber is omitted, and the goods fall from the conveyer into a shoot 53, Fig. 8, which has a hinged portion 54<a> so arranged that the goods can either be deposited in a box 53<a>, or can be passed direct into the air. Charges, conveying.-The conveyer comprises endless chains 6<a> running on water-cooled tracks 40 at the base of the furnace, and on angle tracks 39 in the chamber 5, upstanding arms 6<b>, and transverse charge supports 6<c>. The arms 6<b> are cranked, so that the chains can be located beneath projecting bricks 9<a> and so protected from the direct heat of the chamber 7. Doors.-The ends of the furnace are closed by vertically adjusted doors, which may have chains depending from their lower edges to prevent admission of air.

Abstract: 928,377. Loud-speakers. PHILIPS ELECTRICAL INDUSTRIES Ltd. Jan. 22, 1960 [Jan. 27, 1959], No. 2427/60. Class 40 (4). [Also in Group XXXVIII] In a loud-speaker arrangement particularly for use in stereophonic reproduction, the loudspeaker 1 is placed below a reflector 2 with its vertical axis 4 passing through the focus of the reflector which is formed by rotating a portion of a parabola about a vertical axis, this giving rise to a convex horizontal cross-section gradually decreasing in width from top to bottom (Fig. 4). This results in a reflected beam having an angle of aperture # in the vertical sense smaller than the incident beam's angle of aperture 2 (Fig. 1) for all frequencies, especially those above 1100 c/s. The angle of aperture of the reflected beam, in the horizontal sense, is larger than α.
