Title: Improvements in or relating to the manufacture of cold watersoluble starch products and cold water-swelling starch products
IPC: D21H17/28
Filed: 1945-12-28
Abstract: Cold water-soluble or cold water-swelling starch products are prepared by heating starch or starch-containing materials such as flour or a starch degradation product which is insoluble in cold water, containing at least 20 per cent, preferably 35-50 per cent, by weight of water, with an oily, fatty, waxy natural resinous or bituminous material at a temperature which is above the boiling point of water at the pressure employed in the process and at which the oily &c. material is liquid.  The process may be carried out under increased pressure.  The oily &c. material may be linseed oil, tallow, mineral oils, paraffin wax, Carnauba wax, rosin oil, tall oil or asphaltic mineral oil.  The products, which may be used in the manufacture of sand cores, as colour binders, and for the coating and sizing of paper and textiles, contain 50-60 per cent of the oily &c. material, the excess being removed by pressure or solvent extraction.

IPC: H02M7/523
Filed: 1967-07-31
Abstract: 1,198,487. Inverting. GENERAL ELECTRIC CO. 31 July, 1967, No. 35133/67. Heading H2F. An inverter comprises a pair of current paths between, respective D.C. supply terminals 13a, 13b and a load terminal 14a, each path including a bi-directional switching device S1, S2, and an independent inductor 18, 19, the other load terminal 14b being connectible to the centre-tap of a D.C. supply, the resonant frequency of each inductor 18 (or 19) with the load capacitance 20 being 1-2 times the operating frequency of devices S1, S2. As shown in Fig. 3, each independent inductor 18, 19 is tuned by capacitor 20 to 4050 c/s. whilst the thyristors CR1, CR2 are alternately triggered at 3000 c/s. Each thyristor is bridged by an inverse diode D1, D2 so that each circuit path 16, 17 is conductive for a full cycle of the oscillatory current. Loads 39, 40, 43, 44 having a leading power factor of 0À707 may be switched into the output transformer 35, a capacitor 37 coupled via a 1: 10 transformer 38 preventing a rise in voltage with increasing load. The output voltage may be adjusted by varying the frequency of gate pulses. Further thyristors and diodes may be included in series or parallel with those shown. In Fig. 2 (not shown) the D.C. supply is derived from a bridge rectifier followed by an LC smoothing circuit having a centre-tapped output capacitive divider. Reference has been directed by the Comptroller to Specifications 994,178 and 999,544.

Title: Improvements in compass repeater systems
IPC: G08C19/38
Filed: 1965-08-17
Abstract: 1, 114, 747. Measuring electrically. NIEUWE ROTTERDAMSCHE INSTRUMENTENFABRIEK "OBSERVATOR" N. V. Aug. 17, 1965 [Nov. 19, 1964], No. 35135/65. Heading G1N. [Also in Division G3] In an automatic steering system for a ship, in which a compass repeater compares actual heading with a reference, the repeater transmitter consists of a ring 3 of high permeability material mounted adjacent a conventional magnetic compass 4, (or alternatively acting as flux-gate compass) the ring carrying six equally spaced windings connected in series across an A. C. source 1. Each transmitter winding is connected in parallel with a corresponding winding on the salient pole stator 6 of the receiver. The magnitudes of the currents in the receiver windings depends upon the flux distribution in the transmitter ring 3 which is dimensioned to saturate when the flux due to the A. C. source 1 is in phase with that due to the compass magnet 4, or to the earth's field. When the resultant flux in the receiver is out of alignment with the single phase winding on the locked but angularly adjustable "rotor" 10 an error signal of twice the supply frequency and of reversible phase is induced in the "rotor" winding, and after amplification at 16 this controls the rudder motor 17. A follow-up signal proportional to rudder deflection is obtained from bridge 19, 21, 22.

[Class 27.] Articles stored in separate compartments.-In a coin-operated vending machine of the kind in which the delivery of goods from a number of separate vending compartments is controlled by a single coin-actuated electrical device in combination with a selective switching means associated with electrically operated releasing devices for the respective compartments, each compartment 1, Fig. 2, has a front door 3 connected by a link 48 and lever 46 with a rear door 45 so that the rear door is opened automatically when the front door is opened. A spring 50 may be provided to open the front door automatically, after the release of an electrically operated latch 6. The rear door may be provided with a spring bolt or catch so that the doors cannot be shut until the catch is released or reset by an attendant after refilling the compartment. The latch 6 is carried by a lever 8, Fig. 3, which is raised to unlock the door by the core 10 of a solenoid 9, after the insertion of a coin and the pressing of a button 37. The solenoids 9 of the several compartments are connected in parallel in the circuit controlled by the coin, each solenoid being associated with a button 37 which closes a switch 34, 36 interposed between the solenoid and a main lead. In a modification, Fig. 6, the required solenoid 9 is selected by a switch arm 51 and only one button 37 is provided to close a switch 34a, 51a between the main lead and the switch arm. Coin action, electric-connection; coin-discharging mechanism.-The coin 11, Fig. 4, drops and forms a connection between converging contact members 12, 13. The contact 12 is fixed and the contact 13 is carried by a lever 14 which is moved, when a button 37 is pushed in, to release the coin to a shoot 23 by the core 22 of a solenoid 21. Exhibiting coins.-The coin is retained in the shoot 23 behind a lens 24 in line with an inspection aperture 25 by a lever 26 connected to the core of a solenoid 29. On the next actuation of the machine the coin is released to drop to a moneybox, the lever 26 returning to retain the next coin. A lamp 30 illuminates the coins behind the lens 24. Testing coins; returning coin.-A coin or disc of defective conductivity which fails to make a connection between the contacts 12, 13 is discharged by rotating a spindle 40 having a helical thread 41 engaging the end of a lever 16. The lever 16 is thereby moved to engage a lug 13a on the contact 13. The released disc is deflected by a plate on the lever 16 to a shoot 42 leading to a return shoot 43. The lever 16 also opens contacts 15, 18 to ensure that the solenoids will not be energized during the discharge of the defective coin. Coins of incorrect diameter are returned through shoots 44, 43.

Abstract: Single crystals of aluminium, gallium or indium phosphide are prepared by reacting excess of one of the metals Al, Ga or In with zinc phosphide in an inert atmosphere at 700-1000 DEG  C. When the reaction is over zinc metal and unreacted Zn3P2 are volatilized off at about 1100 DEG  C., and the metal phosphide produced is dissolved in the excess metal present by raising the temperature to about 1250 DEG  C.  The temperature is then slowly lowered to precipitate substantially all the metal phosphide.  The crystals are platelets in which the developed faces are (111) and (<\>bI <\>bI <\>bI).  As a modification the preparation can incorporate a dopant such as ZnO, ZnS, CdS or others along with the selected metal and Zn3P2.
