Title: Logic circuit
IPC: H03K19/10
Filed: 1963-01-14
Abstract: 1,028,703. Tunnel diode logic circuits. SPERRY RAND CORPORATION. Jan. 14, 1963 [Jan. 26, 1962], No. 1522/63. Heading H3T. In a logic circuit comprising a tunnel diode connected to the secondary winding of a transformer, current pulses are selectively fed to the tunnel diode or to the secondary winding of the transformer depending on whether the reflected impedance of the primary circuit is high or low. As described positive going " SET " and negative going " RESET " pulses, Fig. 3, may be applied to a tunnel diode 224, Fig. 2A, to switch it to its high voltage and its low voltage state, respectively. Connected across the primary 212a of transformer 212 is a diode 208 which is biased to the knee of its characteristic by a supply 204, so that it may be switched to its low impedance state by the application of a high level input to one of the diodes 202, or to its high impedance state by the application of a low level input. Assume that at time interval TO, Fig. 3, one of the inputs from source 200 is high, and that tunnel diode 224 has been reset to its low voltage condition giving a low output. The high input switches diode 208 to its low impedance state, making the reflected impedance at the secondary winding 212b also low, so that positive SET pulses from 260 are shunted to earth through this winding and do not change the output. If at time interval 3 the inputs from source 200 all become low diode 208, and hence the reflected impedance at the secondary, becomes high and the tunnel diode 224 is switched to its high voltage state by the next SET pulse (time interval 5), back to its low state by the next RESET pulse from 230 (time interval 6) and so on, each SET and RESET pulse changing the state of the tunnel diode. Thus the output switches from low to high in synchronism with the SET and RESET pulses. If during a high level output period (time interval T8) an input again becomes high, the tunnel diode is returned to its low voltage state by the next RESET pulse at time interval 9 and remains in this state, further SET pulses being once again shunted through the transformer secondary 212b. The arrangement thus constitutes a NOR circuit, a high level output being produced only when all inputs are low. In one arrangement of the SET pulse generator 216 a large voltage is gated to the point 234 by a small switching voltage, Fig. 2B (not shown). A number of logic circuits as described may be interconnected in a " fan-out " and " fan-in " arrangement, Fig. 4 (not shown).

Title: Improvements in or relating to machines for severing a series of boot or shoe blanks or other articles from sheet stock
IPC: C14B5/00
Filed: 1920-01-20
Abstract: 162,065. British United Shoe Machinery Co., Ltd., (United Shoe Machinery Corporation). Jan. 20, 1920. Sheet separators, carriers, and registering devices; pile tables and supports. - In a machine for cutting-out a series of blanks from sheet stock, particularly heel-blanks from leather, the sheets X, Fig. 18, are placed in an horizontal stack on a supplytable 175, the foremost sheet being kept in contact with feeding-pawls 184 by the pressure of weighted followers 177, Fig. 4. The leading sheet is first fed vertically downwards between two guide walls 94, 96, Fig. 18, by means of pawls 184 which are reciprocated by a pair of oscillating arms 194, Fig. 4, actuated from a countershaft 124 through a cam 220 and levers 260, 262, 264. The sheet X is next fed laterally into position between a stationary die 30 and a horizontallyreciprocating support-block 32 by means of a feed finger 100, Fig. 15, which is actuated by a cam on the countershaft 120, a yielding coupling being interposed to prevent injury either to the material or to the feed mechanism. An adjustable swing- ing end-stop 134 limits the forward feed of the strip. In order to reject the end piece of a sheet when there remains insufficient material to make another perfect heel-lift, the bottom edge of the sheet is normally supported upon an horizontal bar 170, Fig. 14, which is withdrawn at the proper time into a recess 171, leaving the remainder of the sheet unsupported so that it may fall away from the machine by gravity. The receding movement of this bar is controlled by the action of a feeler device 234, Fig. 18, which is mounted to turn about a rod 174 and is pressed against the sheet X by a spring 245. So long as there is sufficient material left to form another perfect lift, the feeler 234 is prevented from projecting across the space between the guide walls 94, 96, but when the end of the sheet has passed to the feeler, the latter moves forward into the position shown in Fig. 18. This movement allows a lug 256 projecting from the hub of a cam-plate 198 to engage with a shoulder 254 on a bar 250, which is thereupon rocked about its pivot 251 so as to release a detent arm 226 from its normal engagement with a lug 224 on the controller plate of a one-revolution clutch. A single revolution is thereby imparted to the cam-plates 220, 222, the former of which controls the pawl 184 and feeds downward another sheet from the original stock, as previously described, whilst the latter cam rocks a bar mounted on the shaft 174 so as to move the sheet-supporting bar 170, Fig. 14, into the recess 171, and allow the remnant of the sheet X to fall away. The cut-out blanks are discharged in stacked formation through the tube 50, Fig. 4, at the rear of the cutter, on to the parallel divisions 273 of a tray 272. The main shaft 64, driven by a belt pulley 70, is connected with the countershaft 124 directly through gearing 126, whilst the countershaft 120 is driven by bevel-gearing 122 from the shaft 124.

The girders 9 are extended by members 11 and support the tank container 27, Figs. 5, 6, by means of cradles 25 and brackets 26. Leafsprings 12, Figs. 1, 2, are fixed at one of their ends to the girders 9, and at their other ends are pivoted at 13 to vertically movable plates 14 which by means of channel irons 15 support the wheel axles 16. Connecting rods 18 are pivoted at their ends to the beams 1 and plates 14 to prevent the latter from revolving around the pivots 13. Ackermann-type steering gear may be employed at either one or both ends of the frame. The container when loaded on to the rail waggon is prevented from lifting movement by securing dogs 29, 32, Fig. 6, and a device for securing against movement in the horizontal direction comprises pairs of spring bolt members 33, 34; 35 36, co-operating with securing stops 37 fixed rigidly to the girders 31. The heads 39 of the bolts are bevelled and adapted to engage with inclined faces on the stops 37. Pivoted lever mechanisms 45, 48, may be moved by handles 46 to retract or engage the locking bolts. A sliding bar 52 is provided with cams or stops 51 which are adapted to engage the other ends of the bolts when they are in their locking position, and the bar is of a length equal to the distance between hinged sides 53 of the waggon so that it must be slid into locking position before the waggon sides may be lifted.

Abstract: 307,585. Anode Rubber Co., Ltd., (Sheppard, S. E., and Beal, C. L.). Jan. 21, 1928. Latex, treating. - In the electrophoretic deposition of rubber or other organic substance from an aqueous dispersion, the heat produced by passage of the current is removed by artificial cooling means, thus enabling a high current density to be employed. The invention is applicable to deposition from natural or artificial, vulcanized or unvulcanized dispersions of rubber, guttapercha or balata, or artificial dispersions of rubber reclaims, or of natural or artificial resins or of a cellulose ester or casein with or without admixture of fillers such as colouring substances, vulcanizing agents, and accelerators. The temperature of the bath is maintained between 25‹ C. and its freezing point and is preferably lower than 10‹ C. The cooling may be continuous or intermittent or during a part only of the process. The cooling is preferably effected by passage of a fluid through a hollow anode mould. In the apparatus shown in Fig. 4, each anode 14 consists of a metal tube in the form of a nearly complete ring connected to cooling pipes 27, and is surrounded by a pair of shaped cathodes 15. An additional central cathode 24 may be provided when deposits thicker on the inside are desired. The dispersion is agitated by screws 19 mounted in lateral compartments. A set of moulds and cathodes are mounted in parallel relation along the tank on carriers suspended by cords for easy removal. In a modification the moulds consist of straight tubes mounted horizontally between headers with a common cathode of sheet form on either side. In another modification the anode mould consists of a rotating drum through which cooling fluid is supplied by trunnions. In the apparatus shown in Fig. 8 the anode consists of a rotating drum 61 from which the deposit 65 is continuously stripped, passing subsequently through a drying chamber 67, between pressure rollers 68 and through a second drying chamber 69 and a vulcanizing chamber 70 to a drum 71; in this apparatus the cell itself is cooled by a jacket 64. A glove may be deposited on a suitably-shaped cooled mould; it may be vulcanized on the mould before removal.

Title: Improvements in and relating to the treatment of iron ores for subsequent reduction
IPC: C22B1/18
Filed: 1936-01-22
Abstract: Iron ores are enriched by sintering on a downdraught sintering machine, the resulting nodules being reduced in size, as by tumbling or crushing, and the fines, which contain the major amount of impurities, being subjected to magnetic separation. The coarser ore is preferably fed without sintering to the blast furnace, together with the coarser particles resulting from the sintering and the heads from the magnetic separation.  The middlings from the magnetic separation, and in some cases a part of the heads, may be returned with fresh ore to the sintering machine.  In order to eliminate as far as possible the amount of non-magnetic iron oxide in the sintered product the sintering is done in a reducing atmosphere and the temperature is kept down to about, or preferably below, 1050 DEG  C. The reducing atmosphere may be obtained by limiting the air supply, so that the oxygen is burned to carbon monoxide in the surface layer of the charge, which may contain a heavier percentage of fuel or consist of fuel only; alternatively blast-furnace or coke-oven gas burned with a limited air supply may be used.  The reducing gas is preferably pre-heated.

Title: Improvements in or relating to a windscreen wiper
IPC: B60S1/48
Filed: 1950-01-26
Abstract: 668,128. Windscreen cleaners. TRICO PRODUCTS CORPORATION. Jan. 26, 1950 [Jan. 26, 1949], No. 2115/50. Class 138 (i). Relates to a windscreen wiper of the kind comprising a blade and holder by which it is rockably carried so that the blade assumes an inclined position on the windscreen at the start of each stroke and in which liquid is discharged on to the windscreen, wherein the blade is formed with a passage into which the liquid is introduced and from which it is discharged on to the windscreen in advance of the moving blade through discharge openings on opposite sides of the blade, the openings being alternately opened on one side and closed on the opposite side due to the rocking movement of the blade. Liquid solvent is delivered from a suction operated pump 18, Fig. 1, of known type, through a conduit 19, a nipple 17 on a housing 5 in which is journalled the wiper spindle 4, and a detachable flexible hose 16 to a nozzle 13, Fig. 3, carried by a channelled holder 7 formed with rows of side fingers 8. The fingers 8 loosely embrace an elastic, e.g. rubber blade 6 so as to permit rocking movement of the latter to assume an inclined dragging position on the windscreen 1. The blade 6 is formed with a groove 10 dividing the back of the blade into opposite side margins 11. In the position shown in Fig. 3 the right hand margin 11 forms a discharge passage 9 laterally from the groove 10, the left hand margin engaging against the back of the channelled holder 7. When the blade reverses the left hand margin unseals its discharge passage 9 and the right hand margin 11 then seals the right hand passage 9. Liquid is thus delivered on to the windscreen 1 in advance of the moving wiper blade. The wiper blade is flexible to follow the surface of curved windscreens and the channelled holder 7, 8 is flexible for this purpose.

Title: Process for the manufacture of chromates and dichromates
IPC: C01G37/14
Filed: 1931-01-23
Abstract: Alkali and alkaline-earth metal chromates and dichromates are obtained by the aqueous phase oxidation of chromium or its alloys in the presence of alkalies or alkaline-earths by the use of oxidizing gases (oxygen or air) under pressure at temperatures of say 150-300 DEG  C.  Caustic alkalies, alkali carbonates or bicarbonates particularly the sodium salts, and lime are the specified alkaline reagents, but in the production of dichromates they may be replaced by the corresponding chromates.  When carbon dioxide is produced in the reaction, as when an alkali carbonate is employed, it is either removed in the gas current or in working in closed autoclaves chemically bound, as by the addition of lime.  Ozonized oxygen or air, and halogens are also specified for use as oxidizing agents.  A statement of the art refers inter alia to oxidation of ferrochrome by treatment with fused caustic alkali or with alkali carbonate and saltpetre, or by heating above 1000 DEG  C. with alkali carbonate. The Specification as open to inspection under Sect. 91 (3) (a) is not limited to the use for oxidation of oxidizing gases under pressure. Hydrogen peroxide may be used, and ferricyanides be added when air or oxygen is employed.  This subject-matter does not appear in the Specification as accepted.
