Title: Improvements in or relating to selenium metal rectifiers and methods of manufacture therefor
IPC: H01L21/108
Filed: 1947-08-13
Abstract: A layer of amorphous selenium is formed on a layer of crystalline selenium on a base plate to form a rectifier element [see Group XXXVI] Three methods are described.  In the first, hydrogen selenide is passed through a concentrated solution of ammonia in water to form a saturated solution of ammonium selenide which is diluted with ammonia, water, or alcohol.  The solution is applied, e.g. by painting, to the crystalline layer and then dried with or without heat.  In the second method, the crystalline selenium layer, either dry or moistened with water, ammonia, or alcohol is exposed to hydrogen selenide vapours, to precipitate an amorphous selenium layer.  In the third method, described in the Provisional Specification, the hydrogen selenide is first treated with concentrated ammonium hydroxide to form a red liquid which is diluted, e.g. with alcohol or ammonia, and then painted on the crystalline layer.

Title: Magnetic switching device
IPC: G11C7/00
Filed: 1962-06-12
Abstract: 983,323. Magnetic storage devices. INTERNATIONAL BUSINESS MACHINES CORPORATION. June 12, 1962 [June 12, 1961], No. 22540/62. Heading H1T. [Also in Division H3] A magnetic switching or storage device comprises a magnetic member 22 (Fig. 1) having three apertures in line, a first conductor 32 passing through the first (28) and third (30) apertures and setting the device to a first (cleared) state (Fig. 3b) when energized, a second conductor 40 passing through the first aperture 28 and a third conductor 36 passing through the second and third apertures the effect of energizing the two together being to switch the flux pattern in the device from the cleared state to that shown in Fig. 2b. This Fig. 2b pattern is the " one " binary state and produces an output in conductor 44 when conductor 32 is energized, the flux pattern then changing to the cleared (Fig. 3b) state from which state the " one " can be rewritten. The " zero " state (Fig. 3d) is recorded by a current in conductor 36 alone after the core is first cleared and in this condition a read current in 32 produces no output. When a " zero " is is stored currents in 36 and 40 produce a " zero disturbed" state which also results in no output from a read-current and so still gives the zero effect. The core is preferably of rectangular hysteresis loop material the equal legs 22-25 being of a width equal to half the width of the legs 26 and 27. A matrix is shown in Fig. 4 in which the cores in the columns have their clearing (and reading) windings 34-1, 34-2 connected in series, the cores in the rows having their write and sense winding in series.

Title: Improvements in the filling of cartons, cups or like containers with plastic substances
Inventor: JOHNSON REGINALD FRANK
IPC: B65B43/58
Filed: 1951-09-28
Abstract: 714,267. Filling machines. ROSE BROS. (GAINSBOROUGH), Ltd. Sept. 4, 1552 [Sept. 28, 1951], No. 22647/51. Class 94 (1) [Also in Group V] In a method of, or machine for filling containers with plastic substances, e.g. ice-cream, containers are fed intermittently in spaced succession into register with a filling nozzle from which a rod of plastic substance is continuously extruded at a predetermined rate, a relative movement towards each other is brought about between the nozzle and the container in register therewith to cause the end of the extruding rod to pass into the container and a further relative movement away from each other is then brought about between the nozzle and container at substantially the same rate as that of extrusion of the rod so that there is substantially no relative movement between the container and extruding rod for a given period, and, portion of the extruding rod thus positioned in the container is severed therefrom during that period. Cups 11 are fed along a platform 12 between side guides 13 by an intermittentlymovable chain conveyer 14 having spaced pockets constituted by pairs of wall members 15 arranged to pass through a slot 16 in the platform. Above the conveyer is a nozzle 17 from which a rod 18 of ice-cream is continuously extrcded, the rate of extrusion being such that a charge of ice-cream appropriate to the size of the cups is extruded during each combined movement and dwell of the conveyer. After a cup has been positioned beneath the nozzle. it is raised by a reciprocating bifurcated plunger 21 so that the end of the rod is spaced a short distance from its base and is then lowered on to the platform at a rate equal to that of the extrusion. During the lowering movement a charge is severed from the rod by a pair of opposed wires 26 (see Group V) arranged to move transversely of the rod and at the same time move with the rod at extrusion rate during the severing operation.

Abstract: 1,023,233. Sewing machines. A.O. ZINGG. June 15, 1962 [June 22,1961], No.22704/61. Heading D1G. In a sewing machine, two or more threads from independent sources of supply are tensioned individually and are collected together before being fed through a single needle. The arrangement when used in an embroidery machine enables, it is stated, increased output to be effected by increasing stitch length while maintaining coverage comparable with that obtainable with a single thread and shorter stitches. An attachment incorporating the invention comprises a baseplate 1 which is fixed to the machine head 2 and on which is mounted an upper thread tensioner 3, a lower thread tensioner 8, a switch casing 9 and a thread guide eyelet 10. Casing 9 contains a spindle encircled by a pair of coil  springs the inner ends of which are anchored to said spindle. One spring has a radially-projecting portion which ends in an inverted U-shaped threadguide portion 38. The other spring has a radially projecting portion which ends in an inverted U- shaped thread-guide portion 43. A first thread 4 passes through tensioner 3, around an element 6 of tensioner 8, around a pulley journalled on said spindle, upwardly through guide 38, through eyelet 10 and via a thread take-up 60 and fixed guide 61 to the needle 62. A second thread 5 similarly passes through tensioner 3, an element 7 of tensioner 8, around a pulley on said spindle and via guide 43 and 10, the take-up 60 and guide 61 to the needle 62. Casing 9 is provided with a wire guard 54 also adapted to facilitate insertion of thread 5 in guide 43. In operation, thread tension raises radial portions 36 and 40 clear of contact plates 47 and 48 respectively. Breakage of either thread results in closure of the corresponding contact to energize a solenoid for switching off the driving motor.

Sunken ships, raising.-Apparatus for raising ships comprises submersible pontoons 9 horizontally disposed in a framework 10, and independently submersible lifting-cylinders 14, sliding vertically between guides 26<a> in the framework. Each cylinder carries an electric winch 18, from which a lifting-cable 16 passes downward through a guide-tube 15, a locking-device being provided to grip the cable when under load. Compressed air is supplied to the pontoons 9 and the lifting-cylinders 14 by pipes 27, 26 respectively leading from a control tower 12, Fig. 2, to which leads a main supply-pipe from a reservoir on a salvage vessel. Each pipe has a two-way valve, controlled, preferably electrically, from the control tower, providing for admission or escape of air. A number of such units are grouped above the sunken ship, and partially submerged. The cables 16 are then lowered and attached to the ship, the slack being taken up by the winches 18. The ship is raised off the bottom by expelling the water from all the cylinders 14 through apertures in the lower ends thereof, the cables 16 being gripped by the locking-devices while the cylinder 14 rise in the guides 26<a>. The cylinders are then lowered successively, singly or in groups, the winches taking up the slack in the cables, while the stationary cylinders sustain the wreck. Water is then discharged from a sufficient number of the lowered cylinders to raise the ship still further, and the process is repeated till the ship is lifted to the desired level, so that it may be beached in shallow water. The pontoons 9 may be re-floated after the ship has been raised as far as possible by means of the cylinders 14.
