Title: Improvements in coated or compound sheet material comprising a fibrous layer and a waterproof barrier layer
IPC: D21H19/14
Filed: 1944-06-30
Abstract: A waterproof material for coating or laminating fibrous sheets comprises a rubbery material produced by air-blowing a non-waxy extract precipitated from a warm solution of paraffinic crude oil in propane or other normally gaseous hydrocarbon of 2-4 carbon atoms. The air-blown product may be used as a solution in carbon tetrachloride, naphtha, or a coal tar solvent.  The air-blowing is conducted at temperatures between 450 and 575 DEG  F.  The crude oil may first be freed from wax and resin.  In an example a residual stock from a paraffin base crude is made into a solution with propane at 65 DEG F., chilled by evaporation of propane to -20 to -54 DEG  p F., filtered to remove wax, diluted with more propane, and warmed to a temperature above 77 DEG  F., for example, to 155-165 DEG  F., to precipitate a high molecular weight, naturally-contained, viscous material.  This material may be separated into materials of different viscosity by precipitating in stages at increasing temperatures.

Title: Improvements in or relating to arrangements for producing electric time modulated impulses
IPC: H03K7/08
Filed: 1941-09-26
Abstract: 583,511. Pulse modulation. STANDARD TELEPHONES & CABLES, Ltd., and AMBROSE, D..M. Sept. 26, 1941, No. 12503. [Class 40 (v)] Time modulated pairs of pulses such as F, M, Fig. 2, are converted into single pulses of variable duration. The pulses F of the series occur at fixed time intervals and the intervals between F and the next variable pulse M represent corresponding instantaneous signal wave amplitudes, or the fired pulses F are transmitted pulses of an obstacle detection system, M being the reflected pulses. In the arrangement shown in Fig. 1, the pulses are applied to the grid circuits of valve V1 and of a discharge tube V2 forming part of a conventional saw-tooth wave generator. The pulses are differentiated by the condenser 11 and resistance in the input circuit of V2 so that short positive and negative impulses are derived from each pulse, the positive impulses derived from the fixed pulses being used to synchronize the generator. The saw-toothed output is applied to pentode V3 biased so that is accepts only the wave tips which are applied as negative pulses to valve V4 of a reciprocally coupled pair having two conditions of stability. To ensure proper operation by the fixed pulses which are applied to both valves, the fixed pulses produced by the saw-tooth oscillator may be slightly longer than the fixed pulses in the input train. The variably timed pulses are reversed in polarity by valve V1 and applied as negative pulses to the grid of the other valve of the pair, the output from which therefore, comprises pulses of variable duration. In a modification, Fig. 3 (not shown), a condenser charged.by incoming pulses over a diode controls the anode potential i of a gas discharge tube. A single pulse is just insufficient to raise the potential to ionizing value but the arrival of a second pulse quickly causes discharge. The substantially square topped variable duration pulses in the output of the discharge tube are shaped by a valve which accepts only the central portion of the amplitude range. Pulses of undesired opposite polarity in the input may be removed by a second reversely connected diode.

IPC: B01D53/14
Filed: 1930-04-23
Abstract: In an absorption system for absorbing gas or vapour in oil, means are provided regulated by the flow of gas to the absorber to control the flow of oil thereto.  Petroleum refinery gases supplied through pipes 3, 4 from high- and low-pressure sources, the latter supply having passed through compressors, are delivered to an absorber 1 to which oil, e.g. gas oil, is supplied through a pipe 5.  A ratio control instrument 7 connected with the oil and gas pipes across orifice plates 5a, 2a, by leads 8, 8a, 9, 9a actuates a valve 6 to admit more <PICT:0353079/III/1> oil upon an increase in gas flow.  A tank 16<1> for charged oil is connected to the absorber by a pipe 10 and byepass 11 the oil passing thence through a heat exchanger 20 and preheater 20a to a column still 21 having a superposed rectifying section 22. Stripped oil returns through a float-controlled valve 25 in a pipe 26, or a byepass 27, to the heat exchanger, collects in a tank 29, and is finally pumped through pipe 5 and a cooler 5b back to the absorber, fresh oil being supplied through a pipe 33.  The oil flow through pipe 5 regulates, through the agency of a ratio control instrument 41, the supply of steam through a pipe 39 to the still.  A float 36 in the stripped oil tank 29 controls a valve 37 in the discharged oil pipe supplying the still.  Water is introduced into the rectifier 22 through a pipe 34 and is withdrawn through an outlet 34d, and gasoline vapours are taken off through a pipe 35.

Patent GB-582904-A (GB)
Title: Improvements in the process of enriching cereal grains with natural vitamins
IPC: A23L7/10
Filed: 1944-07-06
Abstract: A process of enriching cereal grain with natural vitamins consists in grinding the scutellum of wheat grains to a powder to reduce the vitamin-retaining properties of the scutellum, and using the ground scutellum to increase the vitamin content of a liquid in which the grain is steeped, thereby enriching the natural vitamin content of the endosperm of the steeped grain. Thus the first batch of a series of batches of wheat grain may be steeped in hot water in the manner described in Specification 519,926, such steeping causing most of the vitamins in the husk and germ to be transferred to the scutellum. The grain may then be gelatinized, and is then dried and milled, the scutellum being separated from the germ and bran and then ground into a powder. This powder is then added to the steeping liquid drained from the first batch before the second batch is immersed therein or simultaneously with the second batch.  This process is repeated for the subsequent batches, the steeping liquid being filtered after each batch is treated, until the scutellum removed contains the maximum quantity of natural vitamins of the B complex that it is capable of absorbing.  Thereafter, all or only a part of the powdered scutellum from a batch is returned to the steeping water. In a modification powdered scutellum or other vitamin B carrier may be introduced into the steeping water of the first batch.  The powdered scutellum may also be employed to enrich the steeping water for rice or other cereal grain.  In another modification, the powdered scutellum is obtained from wheat grains in the natural unprocessed state.

Title: Improvements in and relating to clay product, ceramic composition and associated processes
IPC: C04B33/02
Filed: 1927-05-16
Abstract: 273,258. Vitrefrax Co., (Assignees of Curtis, T. S.). June 22, 1926, [Convention date]. Clay compositions. - Clay products are strengthened by the addition of mineral crystals of long splinter-like form which possess the property of elongating during the firing of the product so as to form a fibrous reniforcing network. An aluminium silicate such as cyanite is particularly suitable. Cyanite ore is heated to 1700 -1800‹ F. to loosen the crystals from one another and from the associated gangue; the impurities are then separated from the cyanite to any desired extent either by wet classification or by quenching the hot ore in water, crushing, and screening it. Reducing conditions are maintained during the calcination to enable the iron oxide impurities to be magnetically separated. For addition to clay products fired at moderate temperatures (cone 4 to cone 12) it is advisable to leave some impurities in the cyanite to lower the refractoriness of the mix, and a suitable composition in this case may contain 68 per cent of pure cyanite crystals, 11 per cent of tourmaline crystals, 7 per cent of cyanite crystals embedded in quartz, 4 per cent of free quartz fragments, and 10 per cent of pyrophylite and associated impurities. In addition to reinforcing the clay product the cyanite neutralizes fire shrinkage as the elongation of the fibre-like crystals fills up the pores produced by the burning out of organic matter in the clay.

Abstract: 1496563 Memory address arrangements ROCKWELL INTERNATIONAL CORP 1 April 1975 [1 April 1974] 13244/75 Heading G4A Digital X addresses used to access the digit positions within a register of a register bank, Fig. 6, of a random access memory, the register bank comprising four 16-digit X0 registers and two 16-digit X1 registers, the X1 registers being "folded" registers each comprising two sideby-side 8-digit sub-registers, are modified by a conditional bit modification circuit, Fig. 2, so that the X0 registers and the first halves of the X1 registers are conventionally accessed by respective addresses 0-15 and 16-23, any address in the range 24-31 being converted by the conditional bit modification circuit to a corresponding address in the range 16-23 so that the second halves of the X1 registers are accessed correctly, the Y address, indicative of a particular register within the register bank, also being modified in order to access the second halves of the X1 registers. Five bit X addresses are employed, the conditional bit modification circuit detecting the presence of the leading bits 11 and converting these to 10, the first bit of a two-bit Y address also being converted to 1. In a modification, Fig. 7 (not shown), the register bank comprises four 12-digit X0 registers and four 12-digit XI registers, none of which is folded, the X0 registers and the last eight digits of the X1 registers being conventionally accessed by respective addresses 0-11 and 16-23, whereas the first four digits of the XI registers are accessed by addresses 24-27. Addresses in the range 24-27 are converted by the conditional bit modification circuit into corresponding addresses in the range 12-15, the circuit detecting the presence of the leading bits 11 and modifying the respective fifth and third bits which become 0, 1. The conditional bit modification circuit comprises input gates 30, 34 and 38, which in the Fig. 6 embodiment receive as inputs the respective bits X 4 , X 5  and Y 1  of the X and Y addresses. If, for example, X 4  and X 5  are both 1, which corresponds to the second halves of the X1 registers, a non-clocked NAND gate 12 enabled by FETs 32, 36 in the # 1+2  clock period (details of the timing periods being given in Fig. 3, not shown) produces a zero output which inhibits FETs 18, 22 connected in series with the gates 30, 38 and output gates 44, 52. Gates 44, 52 are precharged in the clock period # 1  by respective transistors 20, 24 to indicate 0 and 1. Hence in this case the output of gate 30 (and, possibly, that of gate 38, depending on the value of the bit Y 1 ) is modified, the outputs of gates 44, 48, 52 being respectively 0, 1, 1. If, on the other hand, the inputs to gates 30, 34 are not both 1, no modification occurs, gate 12 being enabled to pass the respective signals from the input gates to the output gates.
