Title: Improvements in or relating to ferroelectric memory elements and circuits therefor
IPC: G11C11/22
Filed: 1952-11-25
Abstract: 719,288. Digital electric calculating-apparatus. WESTERN ELECTRIC CO., Inc. Nov. 25, 1952 [Dec. 14, 1951], No. 29783/52. Addition to 717,104. Class 106 (1) A data storage circuit comprises, a ferroelectric element 10 having electrodes 11, 12 on opposite faces, the element being initially polarized in a chosen state, means for applying to one electrode a voltage opposing the polarization of the material and of magnitude half sufficient to reverse the polarization, and means for applying a similar voltage to the other electrode, so that upon application of either voltage individually the .polarization of the material will not be reversed, but the polarization will be reversed when both voltages are applied simultaneously. As applied to a two-dimensional data-storage array pictured in Fig. 7 and shown diagrammatically in Fig. 6, each "cell " of the . f erroe'ectric, sandwiched between electrodes 11 and 12, is initially polarized to a condition represented by C on the voltagepolarization curve, Fig. 1. A voltage E, applied by either electrode 11, 12 separately has no effect on the polarization of a cell, but when equal and opposite voltages are applied 'by electrodes 11, 12 simultaneously the state of the ferroelectric is changed to D and the polarization is left at A when the' voltages are removed. This represents the storage of binary digit "1": binary digit "0" is represented by the state C. Read-out is performed by applying a voltage 2E1 in' the sense which changes the state to point B, so that the ferroelectric element returns to the initial "clear" state C after the cessation of the read-out pulse. A binary number of N, digits may be registered in any row 1 ... N2, Fig. 6, by supplying volt. ages E1 from sources 17 to those vertical columns in which digit " 1 " is to be represented and, simultaneously, supplying an equal and opposite voltage -E1 to the selected horizontal row from a source 18. Other rows can register numbers subsequently in a similar manner. When a +2E1 read-out pulse is supplied by any selected one of the sources 19, reversal of polarization of the " 1 representing cells in the corresponding horizontal row gives rise to simultaneous signals at the output terminals 20, the larger, digit " 1 " signals being readily distinguishable from the smaller. digit "0" signals. A discussion on the optimum dimensions, voltages &c. is included in the Specification.

Filed: 1929-04-08
Abstract: 336,944. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). April 8, 1929. Divided on 336,635. Carbonizing processes; producers. - Gaseous hydrocarbons such as methane or mixtures thereof are introduced, with or without water vapour, into a charge in a coke oven. Temperatures of at least 800‹ to 1000‹ C. are employed. The gaseous hydrocarbons employed may be of natural origin or the waste gases containing hydrocarbons from industrial processes such as the synthesis of ammonia, hydrogenation of coal or the like, or cracking processes may be used. According to an example, waste gas from the synthesis of ammonia containing hydrogen, nitrogen and methane is passed together with steam through a glowing column of fuel undergoing carbonization in a coke chamber, a gas containing hydrogen, nitrogen, carbon monoxide together with some carbon dioxide and traces of methane being obtained. Specifications 128,660 and 249,901 are referred to. The Provisional Specification describes also the production of hydrogen and carbon monoxide by the passage of gaseous hydrocarbons together with water vapour, air or oxygen, or mixtures of these, through a water gas producer. Reference is also made to the passage of gaseous hydrocarbons together with air or oxygen, with or without water vapour, into coal undergoing carbonization. Reference has been directed by the Comptroller to Specifications 3197/10, 7049/10, and 101,152.

Title: Hydraulic jack
IPC: B66F3/42
Filed: 1945-11-09
Abstract: 605,209. Hydraulic jacks. PAGE, H. E. Nov. 9, 1945, No. 29990. Convention date, Nov. 10, 1944. [Class 78 (iii)] A hydraulic jack adapted for rapid engagement with the load comprises a body formed with a ram cylinder 6, a reservoir R and two coaxial pump cylinders 62, 63 of different diameters. The small cylinder 63 is connected with a valve bore 15 having gravity-seated balls 74 and 75 controlling communication with the ram cylinder and reservoir respectively, and lifting at the pressure and suction strokes of the pump piston. The large cylinder is connected with a second valve bore 10 similarly provided with check valves 67 and 68. Valve 68 is adapted to be unseated by a pressureactuated plunger 70 when the pressure in the ram cylinder rises to a predetermined value determined by a return spring 69, there being a communication 23 from behind the plunger to the ram cylinder. During initial operation of the pump, with the ram unloaded, both pump cylinders are effective to bring the ram rapidly up to the load when the consequent rise in pressure causes the plunger 70 to unseat valve 68, so placing the larger pump cylinder in permanent communication with the reservoir so that the smaller high pressure pump cylinder is then alone effective to raise the load. In the particular construction shown the ram is of the double lift type and has inner and outer telescopic sections 33 and 31, the passage to the cylinder space of the outer section in which the inner one works being controlled by a check valve 49 unseated by a fixed abutment 50 when the ram is retracted. Retraction is effected by screwing out a valve 80 controlling a direct passage 26 from ram cylinder to reservoir. The twin pump plunger 60a, 60b is actuated against a return spring 87 by either of two cams 85, 86 on a rock shaft 82. One cam is larger and gives a longer stroke than the other, and selection is effected by the direction in which shaft 82 is worked, or by changing the handle 92 to an alternative and diametrically opposite socket in a boss on the shaft.

Abstract: <PICT:0979813/C4-C5/1> <PICT:0979813/C4-C5/2> A signal encoder comprises a glass substrate 92, a conductive film 90, an electroluminescent layer 88, column electrodes 86, a black glass enamel layer 84 provided with holes 82, and row photoconductive strips 55 each of which lies between and is in contact with two electrodes. The electrodes 54-66 on one side of the strips 55 are earthed and the electrodes 68-80 on the other side of the strips are connected through corresponding resistors to the high voltage terminal 50 of the earthed voltage source 50, and the junction of each electrode and the corresponding resistor is connected to a corresponding one of the electrodes 10-22 of the electroluminescent digit display device shown in Fig. 1. The conductive film 90 is connected to the terminal 50 of the source 52 and each of the column electrodes 86 is connected through a corresponding switch 0-9 to the earthed side of the source 52. The construction can be modified by using physically separated individual photoconductive elements and electroluminescent elements arranged in rows and columns or by using separate row and column elements, provided all the photoconductive elements in each row are electrically in parallel and all the electroluminescent elements in each column are electrically in parallel.

Title: Fans for hydrocarbon motors
IPC: F04D25/02
Filed: 1921-11-14
Abstract: 171,410. Wills, C. H. Nov. 12, 1920, [Convention date]. Driving-gear.-A fan used with an internalcombustion engine is driven through a yielding connection which permits slipping when the fan - reaches a certain speed. The driving shaft 2 carries a sliding sleeve 5 with an annular flange 4 on which the fan 1 is freely mounted. The sleeve 5 has circumferential oil grooves 6 and a hollow conical extension 8 which acts as a clutch with the conical bushing 10 on the fan hub. A compression spring 11 is inserted between the sleeve 5 and a ring 12 and ball bearings are provided between the shaft and the casing. An opening 16 is made in the sleeve 17 for the admission of oil and communicates with the channel 19 in the shaft so that oil is conveyed to the front part of the clutch chamber and thence between the clutch members to the bearings. When the shaft 2 rotates at a low speed the spring 11 holds the clutch members in engagement and the fan rotates with the shaft. At high speed the load on the fan tends to produce slipping and the thrust of the fan causes the fan to move outwardly against the spring thereby reducing the frictional engagement and permitting the shaft to over-run the fan.
