Abstract: 441,496. Boot - making machines. POCHIN, H. W., and MILLMAN, C. H., (Representatives of POCHIN, H. S.) and BROMLEY, J. H., Standard Works, Evington Valley Road, Leicester. July 20, 1934, No. 21310. [Class 17 (i)] Sole-laying.-In a twin sole-laying machine a single treadle controls both presses, partial depression of the treadle applying light clamping pressure to one press, mechanically, by a system of linkage, full depression applying full clamping pressure to the same press and releasing pressure in the other press, depression thereafter applying the light and full pressures to the other press, and so on alternately. A pair of press pads b are each provided with a pressure arm e carried by a lever f actuated by an arm f connected by a resilient link g with one end of a lever h the other end of which is linked each to one end of a cross bar k resiliently connected to a treadle l<1>. The treadle also actuates a clutch shifter n rise of which causes a cam i to rotate half a revolution, raising the operative end of the lever h to exert full pressure in the corresponding press. When one press is under full pressure the corresponding end of the bar k is locked, so that partial depression of the treadle depresses the other end only. In a modification, the bar k is actuated by a lever q, Fig. 5, having pin-and-slot connection with an arm p<2> partially encircling a driven shaft p and frictionally clamped thereto by a complementary member p<1> pivoted to the arm p<2> and to a thrust rod o resiliently connected to the treadle.

Title: Improvements in or relating to magnetisable divided bodies or compacts
IPC: H01F1/24
Filed: 1947-08-06
Abstract: 625,627. Making magnetizable bodies. GAUT, G. C., MOORE, N. C., and PLESSEY CO., Ltd. Aug. 6, 1947, No. 21337. Drawings to Specification. [Class 83 (iv)] [Also in Group XXXV] A magnetizable body is formed by compressing together face-to-face, flakes of ferromagnetic material which thereby cohere whether or not a binder is present. Such a body may be used as a core for power or audiofrequency chokes and transformers. A ferromagnetic powder, e.g. of oxide, electrolyticsilicon-, or nickel-iron, of appropriate size selected by screening, is dropped from a hopper on to a vibratory or other feed-shoot which feeds it through rollers by which it is flattened into flakes. The flakes may be annealed and re-rolled several times. A final anneal at 900 C..for one to two hours in cracked ammonia or hydrogen is given after mixing the flakes with silica, fused magnesia, zirconia, alumina, thoria or kaolin which prevent sintering together of the flakes, and is fed to mixing conveyer by another shoot. After annealing, the magnetic flakes are separated from the other material in a magnetic separator or a weight classifier, given an oxide coating at 200-250 C. in air, and compressed at 15-30 tons/sq. inch in the manner described in Specification 589,863. Before compression a lubricant such as stearic acid in ether may be added. The compressed body may be impregnated with wax or a synthetic resin; e.g. chlorinated naphthalene wax at 150-160 C. and varnished, e.g. with phenol formaldehyde type varnish.

Title: Silicon gate complementary mos dynamic ram
IPC: G11C11/408
Filed: 1973-05-04
Abstract: 1361780 Random access stores MOTOROLA Inc 4 May 1973 [2 June 1972] 21374/73 Heading G4C A monolithic random access memory (Fig. 2A) comprises an array of dynamic MOS device storage cells 133 which are selected by row and column addressing CMOS circuitry there also being CMOS circuitry for refreshing the contents of each cell. A precharge circuit is also provided. As described the array is divided into an upper and lower section 171, 276, one of which is selected in accordance with bit A4 of row address bits A0-A4. The remaining address bits A0-A3 select one of NAND gates 230 to apply an enabling signal to a row selection circuit 147; the latter also receives, for the upper section, a clock signal R and delayed clock signal R<SP>1</SP> from circuitry 245 or, for the lower section similar signals R, R<SP>1</SP> from circuitry 250. The signal R (or R) results in a read control signal being applied to the selected row of cells to cause read out of data via data bus 185 and column refresh circuits 137 to write/refresh data bus 186, refreshing being effected when circuit 147 provides, in response to signal R<SP>1</SP>, a signal at the write refresh control terminal of the selected row of cells. The data from a selected cell in the selected row is gated to the data out terminal 130 under the control of column address bits A5-A9 which results in one of CMOS NOR gates 267 applying an enabling signal to an associated CMOS selection and amplifying circuit 139 so that data is read from the selected bus 186, provided a chip enable signal 128 is positive. During a write signal the refresh circuits 137 are isolated from the data bus, the selected bus receiving a signal via transistors 253, 251 from the data-in bus 129 for entry into the selected cell. In the absence of a chip enable signal the input output terminals are isolated from the data bus to allow bussing of a number of random access stores in parallel. The cells each comprise three N-channel transistors (178, 179, 180, Fig. 2b, not shown) with a storage capacitor connected between the main electrode of transistor 180 and the gate electrode transistor 178, write refresh data being fed to the main electrode of transistor 180 and write refresh control signals to its gate. Read out data is taken from one of the main electrodes of transistor 179 receiving a read control signal at its gate.

Title: Screw-cutting die-heads
IPC: B23G5/12
Filed: 1932-07-30
Abstract: 402,887. Screwing die-heads. HERBERT, SIR A., Dunley Manor, near Whitchurch, Hampshire, DRANE, H. A., 77, Northfield Road, Stoke, and MALLINSON, H., 33, Christchurch Road, Radford, both in Coventry. July 30, 1932, No. 21538. [Class 83 (iii).] In a screwing die-head wherein the diameter of cut is adjusted by rotation of a cam-sleeve and opening and closing is effected by axial movement of the sleeve, the rotational movement is effected by means of a worm rotatable in a collar splined to the sleeve and engaging worm-teeth on the die-head body. The tangential chasers 11 are secured to pivoted carriers 12 biassed to the open position by radial springs 16 and adjusted to the cutting diameter by rotation of a sleeve 17 having eccentric cam surfaces 20, parallel to the axis of the head, co-acting with lugs 19 on the carriers. This rotation is effected by a worm 22, accessible through a hole in the sleeve 17, which is rotatably mounted in a collar 23 splined to the sleeve and engages teeth 21 on the body 13. Opening of the head during its rotation is effected by axial sliding movement of the sleeve 17 through a yoke engaging a groove 28 in the sleeve and prevented from advancing with the head, towards the close of the screwing operation, by means of a stop on the work-holder or on the machine frame. The edges of the cam surfaces 20 and lugs 19 are bevelled at 29 and 30 to facilitate closing of the head when the sleeve 17 is again held axially whilst the head is being retracted from the work. The sleeve 17 is held axially in the closed position shown by means of a transverse pivoted catch 36 pressed outwardly by a spring to cause its outer bevelled surface to engage a similar surface on a recess 38 in the sleeve, the action being such that when the sleeve has been moved rearwardly by the yoke, the catch is depressed out of the recess 38 and the sleeve is then free to be moved rapidly by axially arranged springs in the collar 23 engaging a rear flange 32 on the sleeve. Axial movement of the sleeve in the closing direction is limited by the flange 32 and in the opening direction by a radial screw therein engaging an axial slot in the collar 23. Radial movement of the chasers is limited by pins 30a on the body 13.

Filed: 1960-06-21
Abstract: 939,602. Charging shaft furnaces. UNITED STATES STEEL CORPORATION. June 21, 1960 [June 23, 1959], No. 21685/60. Class 51 (2). [Also in Group XXXV] In a shaft furnace for indurating balled iron ore fines, the speed of traverse of a conveyer for feeding the balled fines is controlled in dependence on the relative permeability to furnace gas of the burden, measured at the spot to which the feed is being delivered. As shown, Fig. 1, a shaft furnace 1 has a hood 16, stack 17 and a conveyer belt 12 which delivers balled fines to a burden B. Air is introduced at the bottom of the burden and combustion gases pass through to the top of the burden and escape through the stack. The conveyer belt 12 is mounted on a movable carriage 13 which is caused to traverse the top of the burden by a variable-speed motor 15. A thermocouple 19 and an anemometer 18, measuring temperature and velocity of the furnace gases, are positioned on the carriage 13 so as to be adjacent to the spot on which the conveyer discharges the fines. By an automatic electric control system (see Group XXXV) the permeability of the bed, which is stated to be proportional to the velocity of furnace gases at standard temperature is computed by electrically multiplying the anemometer reading by the ratio of standard temperature, in degrees absolute, to the measured gas temperature; a signal dependent on the computed permeability is then employed to control the motor 15 so as to vary the rate of traverse of the conveyer and maintain the permeability of the burden constant. Specification 725,204 and U.S.A. Specification 2,739,800 are referred to.
