Abstract: 1,222,236. Charging blast furnaces. SUMITOMO KINZOKU KOGYO K.K. 15 May, 1968 [20 May, 1967; 20 Dec., 1967], No. 23179/68. Heading F4B. [Also in Division C7] Apparatus for charging a blast furnace comprises a large ball valve 9 and hopper 10, hoppers 7 feeding a shoot 11 and said hopper 10, a central hopper 1, shoot 4 and ball valve 3 and inner and outer partition walls 15 and 16 extending downwardly into the furnace shaft. Initially, coke is fed into outer annular space A from hoppers 7 and hopper 10 by raising said hopper 10 and thus allowing coke to fall over the outer partition wall 16. Then ore &c. is fed from hoppers 7 and hopper 10 into the central annular space B by opening ball valve 9. Finally, coke is fed to the central space C from hopper 1 and shoot 4 through ball valve 3. Offtakes 35 feed gases through an annular pipe 36 to a duct 37 and offtakes 22 feed top gas through annular pipe 23 to a duct 24. Gases from duct 37 are washed, filtered and compressed and fed to a beating-reformer (41, Fig. 2) where they are heated to 1000-1500 C., mixed with hydrocarbons which convert any C0 2  and H 2 0 to CO and H 2 , and are then blown into the furnace through tuyeres 45 via duct 43 and bustle pipe 44. Oxygen is supplied through duct 46 and blowpipe 47, a further quantity of hydrocarbon being supplied at 48. The O 2  reacts with the furnace coke and the additional hydrocarbons to produce further reducing gases which react with the ore. The coke can be wholly or partly replaced by coal, which carbonizes in situ. Top gas from duct 24 is also cleaned and used as combustion gas in the heating reformer.

Filed: 1959-07-07
Abstract: 920,002. Tape recorders; pause controls. PHILIPS ELECTRICAL INDUSTRIES Ltd. July 7, 1959 [July 9, 1958], No. 23333/59. Class 40 (2). Of the three latchable keys 1, 2, 3 controlling the usual drives of a tape recorder, the record/ playback key 2 can be pressed further, beyond its latched position, Fig. 5b, to a position, Fig. 5c, at which it acts as a pause control. The engagement of the pinch-roller 19 with the capstan 17 is achieved by a resilient profiled plate 32 which advances a slide 20, carrying the pinch-roller 19 in the direction of the arrows 20<SP>1</SP>. Further depression of the key 2 causes the tip of the plate 32 to engage a fixed abutment 30 and their consequent flexure allows sufficient retraction of the slide 20 to disengage the drive. The keys are profiled to engage a spool-brake actuator 5, which provides latching for any depressed key at a step 8. The key 2 is further recessed at 7 so that during its actuation as a pause control, Fig. 5c, the actuator 5 may rise to apply the brakes temporarily. A " STOP " bar 4 is connected to release any latched key, whereupon braking is applied and the pinchroller 19 fully withdrawn from the capstan 17 (Fig. 5a, not shown).

Title: A Thermal Printing Device
IPC: B41J2/32
Filed: 1968-05-20
Abstract: 1,175,658. Selective printing. NATIONAL CASH REGISTER CO. 20 May, 1968 [19 June, 1967], No. 23878/68. Heading B6F. A thermal printing device for printing on a thermally-sensitive record material 31 comprises a first set of electrically resistive printing elements 12 and a second set of electrically resistive printing elements 14 crossing the first set to form a matrix of thermal printing locations such as 22 where an element 12 and an element 14 cross, and electrical supply means for the first and second sets whereby printing on the material 31 occurs in the vicinity of those matrix locations which are subject to coincident current energization. The current heating in a single element is insufficient to affect the material 31 whereas coincident energization of a pair of elements is sufficient to do so at the crossing point of the elements. The elements 12, 14 may be assembled on either side of an insulating substrate 10, for example made of silicon dioxide, or may be separately mounted on a pair of substrates (28, 34), Fig. 1, not shown, the material (32) being placed between the assemblies. Each element may be formed of electrically resistive material such as tin oxide, rhenium or tantalum. Coatings of conductive material such as copper or gold may be applied to the elements between crossing points (Fig. 3, not shown).

Patent GB-823757-A (GB)
Title: Timing device for electric switches
IPC: G07F15/12
Filed: 1957-07-29
Abstract: 823,757. Switches held set and freed mechanically; retractive switches; retarding action of switches. NATIONAL REJECTORS Inc. July 29, 1957 [Nov. 5, 1956], No. 23920/57. Class 38 (5). A timing device for a coin-actuated switch has an escapement element with a slot therein, in which is arranged a switch actuator, the slot having changes of surface intermediate its ends that prevent an uninterrupted path through the slot for the actuator when moved by a coin, thereby giving a time delay to the movements of the actuator. In one form, Figs. 1, 2, a coin shoot 28 is formed by plates 24, 26, the plate 26 having an arcuate slot 30. The escapement member 34 is pivoted at 32 and the switch actuating arm 48 has a bent-over part passing through the slot 38 in member 34 and through the slot 30. Insertion of a coin at the top of shoot 28 moves the arm 48 clockwise, the initial undelayed movement being sufficient to operate the switch 42, and the remainder of the movement being delayed by the oscillations of the member 34 due to the passage of arm 48 through the sinuous part of slot 38. When the coin moves past the arm 48, the latter returns under the action of a spring in switch 42 with a similar delay, the switch being operated when the arm 48 enters the wider upper end of slot 38. In another form, Figs. 6, 7, the escapement member 98 has a toothededge slot 102 and is biased counter-clockwise against a stop 99 by its weighted left-hand end. The actuating arm 112 extends through the slot 102 and the arcuate slot 78 and across shoots for coins of different sizes. A coin causes oscillation of the member 98 about its pivot 82 due to the downward movement of the arm 112 through the slot 102, the switch when closed at the beginning of the movement energizing a motor to rotate a cam 116. The latter acts on a spring-biased lever 88 pivoted at 84, so that when the coin clears the arm 112, the member 98 is moved alternately clockwise and counter-clockwise by a roller 94 on the lever 88 and by its bias respectively. The arm 112 is thus allowed to return upwards tooth by tooth to reopen the switch with a delay.

Filed: 1952-09-29
Abstract: 722,161. Fuel injectors. DAIMLER-BENZ AKT.-GES. Sept. 29, 1952 [Sept. 27, 1951], No. 24358/52. Class 7 (3). The valve of a fuel injecton nozzle seats at 14 and is provided with an extension 18 having an end portion 19 which produces a finely atomised conical jet for the first portion of the lift of the valve which changes to a concentrated cylindrical jet as the valve lifts higher. The contracted portion 18 meets the slightly conical portion 19 in a sharp edge 20 which is positioned slightly below the end of the outlet orifice 15 when the valve is closed. At idling conditions the valve is not raised sufficiently for the part 19 to move into the orifice 15 and the fuel is sprayed in a finely atomised cone by the lower end of part 18. When the engine is under load the greater fuel supply causes an increased valve lift and when the part 19 moves into the orifice 15 the conical jet is replaced by a dense cylindrical jet with a hollow core. The initial conical jet lasts approximately for the period of ignition-lag and facilitates ignition. The part 19 and the wall of the aperture 15 are formed slightly conical so that the annular gap therebetween increases with increased valve lift.
