Filed: 1927-10-14
Abstract: 303,584. Barker & Co. (Coachbuilders), Ltd., Ridlington, J., and Fensom, W. T. G. Oct. 14,1927. Mountiny electric lamps in lanterns. - A vehicle lamp is provided with a reflector 1 carrying an electric lamp bulb 3 and pivotally mounted in a fork 4 which is axially rotatable within the lamp casing 8, and with means operable from the driver's seat both for rocking the reflector in the fork and for rotating the fork in the lamp casing. The two movements may be controlled independently by electrical, hydraulic, or mechanical means, or by a combination of two or more of such means, or the two means may be intercoupled so that a compound movement can be imparted to the reflector and a source of light by a single movement of a suitable controlling medium. In the form shown in Fig. 1, a bracket 11 on the back of the reflector is connected by a link 12 to a bell-crank arm 10 mounted on the spring-controlled core 9 of a solenoid contained by or formed by part of the stem 6 of the fork 4. Instead of a single spring-controlled solenoid, a double solenoid may be employed to actuate the reflector in both directions. An arm 13 is fixed to the stem 6 of each lamp, and the arms 13 of a pair of lamps may be coupled by a link 14, Fig. 3, which is connected by a link 17 to an arm 16 fixed on a spindle 15. Each arm 13 has a boss 13<1> carrying a spring controlled and insulated finger 21 bearing against contacts 19 on an insulated plate 20 on the back of the socket 7 of the lamp caising, forming a switch for opening or closing the circuits of the solenoids. The forks 4 may be rotated by rotation of the spindle 15 from the driver's seat as by means of a hand lever 24, Fig. 5, and the rocking of the reflector by means of the solenoids may be controlled as by means of a tumbler switch 25 on the lever 24. A locking device may be provided for holding the reflector in any desired position after its adjustment, and preferably an inter-couple is provided between the means employed to rock and rotate the reflector and the means employed to operate the locking device so that the locking device is released before the rocking and rotational movements commence and is restored after said movements are completed. A spring-pressed plunger 26 mounted on the interior of the lamp casing has a conical-shaped head 27 adapted to engage the back of the reflector, which may be roughened for this purpose, or in any one of a series of recesses 29 in a flanged plate 28 mounted on the back of the reflector. The plunger may be self-acting, or it may be controlled positively by electrical, hydraulic, or mechanical means. According to the Provisional Specification, the reflector may be rocked and rotated by pneumatic means, and more than one locking plunger may be employed.

Patent GB-297682-A (GB)
Title: Improvements in the manufacture of loaded conductors
IPC: H01B11/14
Filed: 1928-09-24
Abstract: 297,682. Electrical Research Products, Inc., (Assignees of Wentz, J. F.). Sept. 24, 1927, [Convention date]. Addition to 296,979. Loading circuits to improve transmission.-In order to prevent loss of inductance while laying a loaded submarine signalling cable, the cable is passed through an alternating current field sufficient to saturate the loading material of the cable, and a direct current field opposite in direction approximately equal to the value of the earth's field to which it will be subjected when laid. The cable 6 passes through a winding 7 connected to a source 8 of direct current which is in series with an adjustable resistance 9. The winding 7 is also connected to an alternator 10 through a transformer 11 and adjustable resistances 12, 13. An iron core choke coil 14 tends to prevent alternating current from flowing in the direct current circuit. As the laying operation proceeds, the cable moves out of the coil and the effect of the alternating field weakens to zero, the direct current field becoming that due to the earth's field. Preferably, the frequency of the alternating current is between twenty and sixty cycles per second. To avoid the difficulties due to skin effects in the loading material, the frequency should not exceed one hundred and fifty cycles per second. Specification 224,827, [Class 36, Electricity, Conducting &c.], is referred to. The Specification as open to inspection under Sect. 91 (3) (a) comprises also a direct current field of twice the value of the earth's field. This subject-matter does not appear in the Specification as accepted.

Filed: 1973-06-11
Abstract: 1428219 Coating textile tubular jackets ASHIMORI KOGYO KK 11 June 1973 [12 June 1972 11 Jan 1973] 27731/73 Heading B2E [Also in Division D1] A method of forming a coating of rubber or a synthetic resin of uniform thickness on the external surface of a tubular textile jacket made of woven or knitted fibres comprises passing the tube 1 through a bath 3, Fig. 8, of coating liquid 4 containing the rubber or resin, and solidifying the coating liquid coated on the tube, wherein a flexible hollow annular member 9 (Div. F2) is inserted in the tube to inflate it to circular-cross section and maintained at a constant distance from the coating bath 3, the coating being solidified while the tube is inflated by the device. The flexible hollow annular member 9, Figs. 5a, 5b, 8 may be made of natural or synthetic rubber, optionally laminate with a layer of cloth and is inflated by a fluent substance such as a fluid or powder so that the outer portion 10 of tube is tensioned while the inner portion 11 is compressed. The weight of the inflated double tube 9 may be enough to prevent it moving upwards with the tube 1 emerging from the bath after passing round a reverse roller 5 or the annular member may be held by an endless cord or belt 16 wound round annular member 9 and restrained by a holder 17, Figs. 7, 8. The holder comprises a body provided with a roller 18 round which the cord or belt 16 is wound and rollers 23 which co-operate with rollers 24 outside the tube 1 to prevent the holder moving with the tube 1. In another embodiment the tube 1 passes vertically downwards through an aperture in the floor of a coating bath and the holder is placed above the bath, Alternatively the annular member may extend round the reverse roller 5, Fig. 8, with the holder 17 positioned above the level of coating liquid in the bath or the holder may be positioned on the side of the roller 5 remote from the double tube 9 with the cord or belt 16 passing round the roller 5. The preferred materials for the tube are natural and synthetic organic fibres and inorganic fibres, such as cotton, linen, glass regenerated cellulose, polyamides and polyesters. The coating may be in the form of a latex, solution or paste of natural or synthetic rubber, or a synthetic resin e.g. p.v.c. plastisol optionally blended with chloroprene. When the tube is loosely woven or knit a more viscous pre-coating is first applied as solution, latex or paste to fill the interstices of the fibres. The pre-coating may be of the same material as the outer coating, and may be forced into the material of the tube by passing the tube through a rigid annular scraper.

Abstract: 709,836. Actuating signals on trains. WESTINGHOUSE BRAKE & SIGNAL CO., Ltd., and TILLOTSON, P. Nov. 7, 1952 [Nov. 29, 1951], No. 28008/51. Class 105 In cab signalling apparatus of the kind in which the aspect of a distant signal is indicated by means including two magnets placed one ahead of the other on the track and actuating a polarized relay on the locomotive, in order to prevent the driver unwittingly passing a home signal at "stop" on the same post since the track apparatus will have given merely a cautionary "distant signal on" indication and perhaps caused the driver to relax his attention to look for the home signal, both the track magnets are provided as electromagnets, the one first encountered by the locomotive being energized only when the home signal is at "clear." Preferably, means are provided for indicating at the signal box that the clearing of the home signal results in the energization of the first encountered electromagnet. As shown, the energizing circuit of the electromagnet 3 first encountered by a train contains a contact unit 6 of the home signal 9 and the energizing winding of a relay 4 or other indicating device. The energizing circuit of the second electromagnet 2 contains a contact unit 7 of the distant signal 8 and is closed when this signal is at clear. The electromagnets 2 and 3 are oppositely polarized.

Abstract: 661,641. Making engine cylinders. SPAGNOLA, S. Nov. 2, 1949, No. 28065/49. Classes 83 (ii) and 83 (iv). Electric welding; angular bending.-In a method of making a heat-exchange device a cooling fin 10 is built up on a metallic form 1 by winding a metal strip 11 therearound in radially superposed turns and welding the superposed turns together. Figs. 1 and 2 show a steel cylinder 1, for an internal combustion engine, carried in a motor driven chuck 2 mounted on a frame 4, 5, 51 which supports a hand-operated traversing screw 36 and a guide shaft 37 parallel with the cylinder 1. The metal strip 11 is fed tangentially on to the rotating cylinder 1 through guide rollers 19, 20 and is pressed against the cylinder surface, or the underneath turns of the strip, at the initial point of contact 12 therewith by a roller 13. The rollers 13, 19, 20 are supported by a spring-pressed frame member 14 which is pivoted to a frame member 17 upstanding from a carriage 35. The carriage 35 is supported for movement on the guide shaft 37 by the traversing screw 36 so that the roller assembly may be moved along the cylinder to build up each fin 10 in turn, a calibrated disc 39 being provided at one end of screw 36 to assist in accurately spacing the fins. The welding of the turns may be effected by any suitable carbon or metallic electrode method or by gas arc. In the arrangement shown it is effected electrically via a control unit 48 and a transformer 28, the secondary leads of the transformer being connected to the roller 13 and chuck 2 respectively. The roller 20 is used to preheat the metal strip by means of a tapping from the secondary of the transformer through a rheostat 43 and switch 42. A switch 57 in the primary circuit is arranged for automatic opening, via a bar 60 carried by the frame member 14, when the fin 10 is built up to the required height. The electric feed to the motor 8 driving the chuck 2 is controlled by unit 48 so that the motor speed varies with the welding load. Where the cylinder has a connecting flange as at 75 it may be built up as shown in Fig. 3 by winding and welding together superposed, successively shorter rows of square section wire, the flange being subsequently machined to line 78. In alternative arrangements two or more fins 10 may be built up simultaneously by providing an elongated roller 13 with either similarly elongated rollers 19, 20 or a row of separate rollers 19, 20, or the strip may be worked helically around the cylinder by moving the roller assembly on rotation of thereof, the superposed turns being wound with the same or reverse direction of travel of the roller assembly. The metal strip 11 may be hollow to provide for cooling fluid to be passed therethrough.
