Title: Improvements in or relating to the heat treatment of flour and wheaten stock
IPC: A21D6/00
Filed: 1929-08-23
Abstract: 338,603. Jones, D. W. Kent-, Chitty, C. W., and Woodlands, Ltd. Aug. 23, 1929. Treating with air; treatment by heating and ,.cooling; treatment by damping. - Flour or wheaten stock is subjected to a heat treatment of brief duration by surface heating means in such a manner that the whole of the flour undergoing treatment is rapidly raised to and maintained at a temperature of about 130‹ to 200‹ F. The heating-chamber is a conduit 12 with a heating jacket 13, a feed hopper 14 being provided at one end and a delivery spout 15 at the other. A shaft 16 extending through the conduit carries radial arms 17 that act as agitators to throw the flour against the wall of the conduit, and some of these arms carry short helical blades 19 that urge the flour along. Other radial arms carry soft leather, balata, or like scrapers to prevent adhesion of flour to the walls 12. The flour is then cooled in an apparatus comprising a rectangular box 21 divided longitudinally into three channels 22, 23, 24 each having a bottom of semicircular cross-section. Each channel has a lining of aluminium, and they are all covered by a lid 26, the lid 26 and the bodies of the channels being provided with lagging 27. Feed worms 28 propel the flow along the channels in series till it escapes through a shoot 34 into a cooling drum. Air passes through the channels in counter-current to the flow, escaping through an expansion box 36 to a pipe 37 through which it is drawn by an ejector. The cooling-drum 38 is cylindrical vessel similar to the conduit 12 and contains a shaft with agitating arms, feeding blades and resilient scrapers. The walls are watercooled and the cooling-jacket is in three sections, water from the top of one section being led to the bottom of the next section. The cold water is fed into the section where the flow is discharged and is taken off at the other end where the flow is warmer. The heated flow may be sprayed with water to replace that driven off by the heatings. Rye or other grain flour may be similarly treated. The whole or a selected part of the mill products. may be treated; if a selected portion is treated this is preferably the lower grade of the flow. By increasing the time or the heat of treatment the product may be suitable for use as a flour improver. Specifications 115,410, 228,841, 263,897, and 310,125 are referred to.

Title: New process for spinning polymers based on acrylonitrile
IPC: D01F6/18
Filed: 1961-07-19
Abstract: Polymers containing 85% or more of acrylonitrile are wet-spun from a spinning solution in dimethylformamide containing at least 10% by weight, based on the dimethylformamide, of cyclohexanone, into a coagulating bath of water, dimethylformamide and at least 10% by weight of cyclohexanone, based on the dimethylformamide. The spinning solution may contain 10-40% by weight cyclohexanone, and the coagulating bath 10-65% by weight cyclohexanone, based on the dimethylformamide contents.  Desirably, the weight ratio of cyclohexanone to dimethylformamide in the coagulating bath is the same as that in the spinning solution.  Filaments so made show, in the as-spun state, fewer cavities perpendicular to the surface and, when drawn, fewer longitudinal fissures and less fibrillation than conventional filaments.

Filed: 1966-06-14
Abstract: 1,075,369. Ignition systems. GENERAL MOTORS CORPORATION. June 14, 1966 [June 28, 1965], No 26357/66 Heading F1B. In an internal-combustion engine capacitor discharge ignition system, an electronic converter circuit inverts a direct current supply voltage, transforms it to higher voltage and rectifies the higher voltage so as to charge the capacitor 62 continuously when the engine is being cranked to start and to charge it in response to a trigger signal derived from amplified ignition signal pulses produced by an electromagnetic pulse generator 9 driven in synchronism with the engine when the engine is running normally after starting. After the engine has started the movable contact 27 of switch 16 is actuated to complete a circuit between the input and output 18, 25. In this position the circuit which includes resistor 126 is no longer energized and transistor 70 therefore responds only to the trigger signals applied to its base 71 from junction 140 to diode 142 as transistor 50 goes non-conductive. With switch 16 in this position transistor 70 and silicon controlled rectifier 84 are triggered substantially simultaneously to conduct by the trigger signals produced by the respective transistors 50 and 40 and sparking at the plug takes place when the terminals 18, 25, 26 are connected the transistor 70 transformer 44, feedback winding 47 and the circuit which includes the resistor 126 are inter-connected with the power source in such a way that the converter circuit oscillates so as to render the transistor 70 alternately conductive and non-conductive so as to open and close an energizing circuit for the primary winding 45 of the transformer 44.

Title: Improvements relating to laminated structures
IPC: D06N7/00
Filed: 1966-06-14
Abstract: 1,131,572. Laminated floor coverings. N. W. HJELM. 14 June, 1966 [16 June, 1965], No. 26448/66. Heading B5N. A laminated structure comprises a base layer 1 to 3 mm. thick bonded to a layer of wood veneer 0À1 to 0À8 mm. thick by a plasticized p.v.c. layer, and an outer transparent layer of plasticized p.v.c. bonded to the surface of the veneer layer remote from the base layer by a transparent layer of plasticized p.v.c., the two layers of p.v.c. bonded to the veneer layer being more highly plasticized than the outer layer of p.v.c. As described the base layer consists of plasticized p.v.c. containing 30-80% by weight of a filler such as ground quartz, asbestos, sand or chalk, and is bonded to a wood veneer 0À1 to 0À3 mm. thick by a 0À1 to 0À3 mm. thick layer of p.v.c. A bonding layer of p.v.c. plasticized like the first bonding layer but somewhat harder bonds an outer wear-resistant layer of thickness 0À1 to 0À5 mm. and of hard but flexible p.v.c. to the veneer. The veneer layer is preferably made very thin, i.e. 0À1 mm., or is perforated so that it is thoroughly impregnated by the bonding layers. The plasticizers used may be tricresyl phosphate or diallyl phthalate. The laminate is produced by applying the bonding layers in turn to the wood veneer, then applying the bottom layer and then applying the top wear layer, all such applications being performed in roller mills, and the material, which is in web form, being fed from roller mill to roller mill. To ensure impregnation of the veneer by the bonding layers these are applied under pressure at high temperatures, by steam or electrically heated rolls. The finished laminate may be cut into squares or blocks.
