Title: Improvements in or relating to direction indicators for motor vehicles
IPC: B60Q1/36
Filed: 1930-09-29
Abstract: 357,791. Road - traffic signals on vehicles. BUSSENIUS, A., 30, L÷btauer Strasse, Dresden, Germany. Sept. 29, 1930, No. 29173. [Classes 40 (i) and 118 (ii).] A pivoted signalling- arm 3 on a motor-vehicle is adapted to be electromagnetically released for free oscillation. The arm 3 carries a counterweight 14 having pins 12, 13 which co-operate with stops 10, 11 on a link 7. The latter has a slot 8 engaging a pin 9 on the casing and is connected to the armature 5 of an electromagnet 4, which when energized draws down the member 7 against the action of a spring 6, the projection 10 thereupon releasing the pin 12 so that the arm 3 is moved up and oscillated by the counterweight. In a modification dispensing with the counterweight, the arm 3 is connected by springs to a pivoted casing so as to vibrate freely when lifted. The armature may open an adjustable switch in its movement, thereby intermittently breaking the circuit so as to give a prolonged vibratory movement to the arm. A mercury switch may be used. In another modification, Fig. 7, the electromagnet 4 lifts the arm 3 against the action of a spring 6, and the armature in its lowest position is arranged to separate two contacts 27, 28 to interrupt the circuit and cause the arm to drop again, the contacts ensuring the repeated lifting of the arm after a short descent. The counterweight 14 may be made of lead and carry an iron segment 14a acting as armature, two coils 4 with pole-pieces 30 being provided. The spring 6 acts in opposition to the magnetic field. Stops on the counterweight may open and close the circuit at predetermined points in the swing.

Title: Low Temperature Blast Furnace and Method of Reducing Iron Ore Therein.
IPC: C21B13/02
Filed: 1967-06-26
Abstract: 1,184,573. Extracting iron. STEEP ROCK IRON MINES Ltd. June 26, 1967 [Aug. 30, 1966], No. 29315/67. Heading C7D. [Also in Division F4] The reduction of iron ore to metalized ore is effected in a low temperature blast furnace 59. The ore with a one third to two thirds excess of reduction material, in the form of coke, coal or lignite of #" to 1" particle size, is introduced as a charge into the top 60 of the furnace which is divided into five zones. Air from an annular preheating jacket, and the top and/or bottom of a central air supply pipe 62 of between one tenth and one half the furnace diameter, is introduced to the charge to burn off gases and volatiles at the top of the shaft in zone one and to provide a pre-heating and pre-reduction zone, zone two. Further preheated air is controllably fed to zones three and four to combust part of the reduction material and form combustion and reduction zones respectively in the latter of which a CO/CO 2  ratio of at least  7:1, and an operating temperature no greater than 2400‹ F. are maintained. The reduced charge which has been passed through zones one to four at a controlled rate, is then cooled in zone five to 400‹ F. and removed from the bottom 61 of the furnace. The iron is then separated from the excess reduction material, which is recycled, by magnetic separators (not shown). The air supply and waste gas withdrawal means (not shown) are so co-ordinated that about 5% of the reducing gases produced in the reduction zone are drawn down through the cooling zone five to prevent re-oxidization of the reduced charge, the remainder of the gases passing upwardly through zones three to one. Natural gas, propane, fuel oil or naptha may be introduced into the furnace through central air supply tube 62 to reduce the consumption of the reduction material.

Title: Improvements in multi-color kinematographic positives, and methods of production thereof
IPC: G03C7/04
Filed: 1932-10-25
Abstract: 414,056. Colour kinematography. THORNTON, J. E., 8, Hill Street, Jersey, Channel Islands. Oct. 25, 1932, No. 29772. [Class 98 (ii).] Mosaic two-colour kinematograph positive films are produced from two, three, or four colour mosaic screen negatives by printing component colour-record mosaic images on opposite sides of a double-coated film through complementary colour filters, and colouring the resulting images by applying a layer of differently coloured colloid to each side of the film, hardening the colloid at the image places by a bleachhardening solution, washing out the unhardened colloid, and removing the bleached silver salts. In place of a double-coated film, a film of half thickness and double width may be used, the resulting strip being divided and the parts cemented face to face or back to back. The colloid may be applied as a layer on a porous paper support, brushed on as a solution, or applied by any other known method of coating. In carrying out the process, a mosaic screen negative film in two, three, or four colours is printed by projection onto opposited sides of a film coated on both sides with a panchromatic gelatin silver halide emulsion so as to form one colour-record, e.g. of orange-red, on one side and the complementary, e.g. blue-green, colour record on the other side. The printing of both sides may be performed simultaneously using an optical system consisting of mirrors or prisms and lenses and red and green colour filters, or successively using a rotating filter having red and green sectors. Alternatively a master negative film in which the component images alternate may be prepared from the original negative, and the images printed in register on opposite sides of the final film from this, or side by side on a double width film using the apparatus of Specification 373,312. In the case of the double-sided film, a light obstructing layer as in Specification 9324/12, [Class 98 (ii)], may be interposed between the emulsions, or both may be dyed yellow to prevent printing through. The images are then coloured by applying colour plasters, consisting of colloid on a support of porous paper, in complementary colours and a bleachhardening bath such as described in Specification 17007/05, [Class 98], to the sides of the film, washing out the unhardened colloid and removing the bleached silver salts with hypo. Specifications 16899/14, 224,569, and 224,573, [all in Class 98 (ii)], also are referred to.

Divided on 409,273 under which a Specification was laid open to inspection under Sect. 91 of the Acts, Oct. 28, 1932. Void [Abridged as open to inspection under Sect. 91 of the Acts, Dec. 27, 1933]. [Class 74 (ii).] A knitted elastic fabric capable of stretching in all directions and used for corsets, girdles, brassieres, elastic stockings, belt and like supporting garments, comprises parallel elastic elements 1 such as rubber covered cords, about which elements 7 are loosely or closely knitted, and interknitted with elastic elements 13 as shown. The elements 7 may be elastic or they may be non-elastic and comprise yarns. Each element may comprise several ends. A limiting element of non- elastic material such as yarn may be run alike with each elastic element 13 to limit the strain thereon. The elements 13 may be much weaker than the straight run elements 1, which may be disposed in the garment so as to extend around the body. They are made to exert a considerable contractive force or grip on the body by being of large diameter, or in large numbers and close together or tightly stretched. The elastic yarns forming the knitted courses may be less numerous, smaller, less tightly stretched, or of coarser gauge or mesh in the knitting, so that the transverse stretch of the garment may be small.

Title: Method and apparatus for controlling the flow of fluent material into or out of a container
Inventor: SMITH CHARLES HORACE
IPC: G01F23/26
Filed: 1966-07-05
Abstract: 1,100,775. Valves. SHELL-MEX & B.P. Ltd. 5 July, 1966, No. 30067/66. Heading F2V. [Also in Divisions A4, B8, F1, F4 and G1] The flow of fluent material into or out of a container through a valve &c. is controlled by a device responsive to the amount of fluent material in the container, the valve &c. being connected to the amount-responsive device by a radio link including a transmitter and a receiver. The fluent material may be a liquid, a powder or gas. For a liquid or powder, the amount in the container may be indicated by the level of the liquid or powder. The levelindicating device may be a capacitance probe, a float, resistor or thermistor probe, or a photoelectric transducer. For a gas, the amount may be indicated by the pressure of the gas in the container, or by means responsive to the concentration of the gas in the container. In one form, as shown, an oil tanker for delivering fuel oil to a storage tank has a solenoid-operated valve in its delivery pipe. The tanker carries a U.H.F. radio receiver which, when it receives a signal, acts through a relay to close a circuit and open the solenoid valve. When the tanker driver puts the delivery pipe into the filling hole of the storage tank, he at the same time places a small U.H.F. radio transmitter on the top of the storage tank. The radio transmitter has at its base a capacitance probe which is passed through a second hole in the top of the tank. Placing the transmitter upon the tank closes a switch to make a circuit so that the transmitter operates. The signal emitted by the transmitter is picked up by the receiver upon the oil tanker, and the solenoid valve in the delivery pipe is opened. Fuel oil is delivered into the storage tank until its level rises to touch a capacitance probe on the base of the U.H.F. transmitter. The transmitter is automatically switched-off, and stops giving a signal. Accordingly, the receiver upon the oil tanker opens its relay switch, to shut the solenoid-operated valve. As modifications, the system may contain an alarm, such as a bell or a lamp, to indicate when the valve &c. has been shut. The transmitter may have a hand-operated override control switch. Other switches on the transmitter may effect further control functions, e.g. actuation of a hose rewind mechanism.

Title: Improvements in or relating to electric contact converters
IPC: H02M1/20
Filed: 1957-09-25
Abstract: 822,117. Converting. SIEMENS-SCHUCKERTWERKE A.G. Sept. 25, 1957 [Sopt. 29, 1956], No. 30117/57. Class 38 (2). Premagnetization current for a switching choke SD in a contact converter circuit is provided by an arrangement of transistors which is so controlled by voltage developed by the switching choke that it passes only during the duration of the current step. The premagnetization current passes through winding V which is actually on the switching choke core, when amplifier transistor T2 is made conductive by current passing through its base-emitter circuit. This latter current flows through transistor T1 as a result of voltage developed by flux changes in winding H on the switching choke, and its value, and therefore that of the current in winding V, is determined solely by the value of resistor W in series with battery U1 in the emitter-base circuit of transistor T1 and not by the voltage developed in winding H. Rectifier G protects the transistors against excessive inverse loading. In a modification transistor T1 lies in the output circuit of transistor T2 (Fig. 2, not shown). The arrangements obviate the need for a basic load to maintain the switching chokes appropriately saturated on no load.
