Title: Improvements in or relating to regenerative steam engines
IPC: F01K19/00
Filed: 1932-09-13
Abstract: 408,637. Steam engines. ANDERSON, W., Glen Cottage, Earls Dene, Low Fell, Gateshead, and BROWN, W., 3, West View, Durham Road, Lanchester, both in Co. Durham. Sept. 13, 1932, No. 25465. [Class 122 (iii).] In a regenerative steam engine of the kind described in Specification 340,291, the internal volume of the heater is arranged so that the water leaves the heater when the ram f has effected about half its displacement on the outward stroke. Part of the pipe d connecting the cylinder and heater acts as an expansion chamber and regenerator as the continued movement of the ram. The pressure has a lead over the temperature during the first part of the compression stroke and prevents too early the conversion of the water into steam. The exhaust valve e is arranged on the part d of the pipe c acting as an expansion chamber. When using high-temperature feed water, the exhaust valve is arranged nearer the heater. During the outstroke of the plunger f, the steam in the heater e expands. Near the end of the stroke, the valve e is opened, and steam passes to the regenerator q, the condensate from which is forced into the pipe c by a pump n past a check valve p. During the instroke, the water is forced into the heater a being initially heated in the part d of the pipe c. When the engine is not working, the water is passed through the heater a and an adjustable valve l to the regenerator q which may comprise a low pressure boiler. The flue gases from the heater a may pass over boiler heating surfaces r.

Title: Plasticizer for ethenoid polymers
IPC: C08L27/06
Filed: 1944-12-19
Abstract: Polyvinyl chloride, polyvinyl acetate or a copolymer thereof is incorporated with less than its own weight of a linear polyester of 1,2-propylene glycol and sebacic acid, the polyester having a molecular weight of 1700-20,000.  The polyesters act as plasticisers, assist working and milling of the vinyl polymers and facilitate dispersion of pigment or fillers therein.  The plasticising action is greater for polyesters of lower molecular weight.  The compositions of the invention may be prepared by mixing and milling on a roller mill, by masticating in a Werner-Pfleider or Banbury-type mixer, by mixing solutions of the ingredients and evaporating the solvent or by preparing an emulsion of the ingredients and coagulating them or drying in film form.  Other plasticisers, e.g. tricresyl phosphate or dibutyl sebacate, pigments such as carbon black, agents such as zinc stearate or fillers such as clay or asbestos may be incorporated in the compositions.  The examples describe the preparation of the polyester by condensing the ingredients in presence of zinc chloride, and its incorporation, together with white lead and stearic acid, with a copolymer of vinyl acetate and vinyl chloride known under the Registered Trade Mark "Vinylite VYNW," on a rubber mill at a temperature of 290-320 DEG  F.  Similar compositions were prepared with tricresyl phosphate, dicapryl phthalate and dibutyl sebacate in place of the polyester of the invention.  A number of tests were made on the four compositions and comparative results are recorded.  The compositions of the invention are particularly suitable as jackets for high-frequency cables (see Group XXXVI).  They may replace rubber for many purposes and are suitable for coating or impregnating fabric or paper or for coating wood or metal.  They may be moulded by injection, compression or extrusion.  Highly plasticised compositions may be used as pressure sensitive adhesives.  In addition to the method given in the example, the polyesters may be prepared according to the method of U.S.A. Specification 2,071,250 or 2,249,950.  The Specification as open to inspection under Sect. 91 covers the plasticisation of ethenoid polymers generally by linear polyesters which are non-crystalline above 30 DEG  C. and which are prepared by esterification of dihydric alcohols and dicarboxylic acids.  As ethenoid polymers it mentions polystyrene, polyvinyl acetals such as the formal and butyral, and copolymers such as those of polyvinyl halides and polystyrenes, polyvinyl esters and polyvinyl acetals. The polyester may be prepared from adipic, a -methyl glutaric, a ,a -diethyl glutaric, pimelic, suberic, azelaic, sebacic, maleic, fumaric or phthalic acid or mixtures thereof, and ethylene glycol, diethylene glycol, 1,2-propylene glycol, 1,3-propylene glycol, butylene glycol, hexamethylene glycol, the a -methyl ether of glycerine or mixtures thereof.  This subjectmatter does not appear in the Specification as accepted.

Abstract: 1,153,428. Semi-conductor devices. MULLARD Ltd. 2 June, 1966 [18 June, 19651, No. 25874/65. Heading H1K. In an insulated gate FET the variation of characteristics due to movement of the drain region depletion layer with the source-drain voltage is reduced either by providing a region of the substrate having a higher conductivity than the major part of the substrate adjacent to the drain region, or by providing the drain region with a higher resistivity region. As shown, Fig. la, source and drain regions 4, 5 are diffused into a high resistivity P-type substrate 1 which has a higher conductivity P-type layer 2 at its surface. The depletion layer associated with drain region 3 extends further into region 1 than into region 2 so that when the source-drain voltage varies the movement of the depletion layer is less adjacent to the surface where the channel is formed. The device may be produced by forming layer 2 by epitaxial deposition on, or diffusion into, a P-type silicon wafer doped with boron to a concentration of 10<SP>14</SP> atoms cm.<SP>-3</SP> The surface of layer 2 is masked with silicon dioxide and N-type regions 3, 4 are formed by diffusing-in phosphorus to give a concentration of 10<SP>20</SP> atoms cm.<SP>-3</SP> Aluminium is evaporated-on through a mask to provide ohmic contacts 7 and 8 to source and drain regions 4, 3 and to form gate electrode 6 over oxide layer 5. In a modification, the lower face of the wafer is provided with a highly doped region (1A, Fig. 1b). The device may be further modified by extending the higher conductivity layer into the wafer to meet the highly doped layer (1A), the high resistivity substrate being reduced to two regions lying adjacent to the outer faces of the source and drain regions, Fig. 1c (not shown). In other modifications, the higher conductivity layer extends only part way between the drain and the source, Fig. 4 (not shown), or is buried below a thin high resistivity surface layer, Fig. 5 (not shown). The buried layer may be produced by ultrasonically forming a cavity in the surface of the wafer, epitaxially depositing the higher conductivity layer and the high resistivity surface layer, grinding the surface with alumina powder to form the required inset regions, and diffusing-in the source and drain regions, Fig. 7 (not shown). In another embodiment the P-type substrate is of a single conductivity and the N+ type drain region (29) is surrounded by a lower conductivity N-type region (30, Fig. 8a). In a modification the lower conductivity N-type region (30) does not surround the N+ type region (29) but extends from it towards the source region, Fig. 8b (not shown).
