Title: Improvements in or relating to methods of making gallium phosphide crystals and to devices utilising them
Inventor: LOGAN RALPH ANDRE
IPC: H01L33/00
Filed: 1968-02-15
Abstract: 1,213,017. Electroluminescence. WESTERN ELECTRIC CO. Inc. 15 Feb., 1968 [15 Feb., 1967], No. 7376/68. Heading C4S. [Also in Division H1] A semi-conductor device is produced by forming a P-type GaP crystal by solution growth, depositing an epitaxial layer of N-type GaP on the crystal, and annealing at a temperature between 450‹ and 725‹ C. The annealed device emits visible radiation (red) with an external quantum efficiency greater than 1%. In an example a quantity of gallium was heated in vacuo, specified quantities of gallium phosphide, zinc and gallium oxide were added and the tube was sealed under vacuum and heated to melt the solution which was then cooled. The resulting P-type GaP crystals was recovered by digestion in nitric acid. The crystal was polished and etched and placed at one end of a boat the other end of which contained a charge of gallium, gallium phosphide and tellurium. The boat was heated in a forming gas atmosphere to melt the charge which was then flooded over the crystal and allowed to cool to epitaxially deposit an N-type GaP layer on the seed crystal which was again recovered by digestion in nitric acid. The crystal was broken into two and annealed in air at 720‹ C. for 16 hours. As shown, Fig. 1C, ohmic contacts were applied to the P-type region 11 and the N-type region 12 by simultaneously alloying a gold zinc wire 16 and a tin dot 14 in a stream of hydrogen. The tin dot was contacted by a gold wire 15 and the device was mounted on a glass header 17 by means of a layer 18 of resin having a suitable refractive index. The external quantum efficiency was measured and found to be 2À1% compared with 0À26% for a device in which the annealing step was omitted. The annealing step may be performed at a temperature of 450‹ to 725‹ C. for 5 to 30 hours in an ambient of air, vacuum, or argon. The digestion of the GaP crystal from the gallium may also be performed with hydrochloric acid.

Title: Improvements relating to capstan lathes
IPC: B23Q5/52
Filed: 1949-03-18
Abstract: 660,699. Lathes; tapping. HERBERT, Ltd., A., and LLOYD, A. H. Feb. 15, 1950 [March 18, 1949], No. 7409/49. Class 83 (iii). A capstan lathe is provided with a switch mounted on the headstock which each time it is operated may effect a change of speed or reversal of the lathe spindle, rods or other projections extending from the turret faces being adapted selectively to operate the switch at a requisite moment during the turret advance. A micro-switch 14, Fig. 1, mounted on the lathe headstock II may by successive impulses be arranged to control either a two-speed motor or a reversible motor for the lathe spindle. Actuation of the switch is effected through the bevelled end 15 of a slidable spring-returned rod 16, also carried on the headstock, and in alignment with a number of rods 21 of different length associated one with each of the turret faces. The rod 16, Fig 1, is shown with an extension 22 fitted to its outer end. Automatic reversal of the spindle assists in returning the turret when a comparatively large tap 24 is used. When using a small tap 27, Figs. 5 and 6, however, breakage of the tap might result from such a practice and in this case the tap is slidably held against rotation between two springs 29 and 30, Fig. 6, in a sleeve member 31. Spring 29 is stronger than spring 30 and spring 17, Fig. 1, for the switch rod. The switch-actuating rod 34 in this case is carried by the tap-holding member 28 and not directly by the turret. A speed-controlling switch and a reversing switch may be carried on the headstock, both operated in the manner described above or the speed changing may be effected as described in Specification 481,895, which is referred to.

Abstract: An apparatus for mixing and spraying liquid reactants, especially for silvering and reducing solutions, or for partially polymerized <PICT:0859688/III/1> resin and catalyst solution which inter-act to produce hardened resin, has a mixing chamber 1 into which the liquids to be mixed are introduced under pressure through symmetrically disposed conduits 2 and nozzles 14, and compressed air through a conduit 18.  The liquids impinge on the surface of a bed of stainless steel wool 4 which provides a mass of fibrous passages in which the liquids intermix and which hold them in contact for a predetermined time before they are expelled as a spray through the orifices 6 and nozzles 14a.  The proportions of the liquids are determined by suitably selecting the sizes of the nozzles 14.  The time during which the liquids are held in contact in the mixing chamber may, for a given pressure, be changed by changing the dimensions of the fibrous passages as by replacing the stainless steel wool by small glass balls.  The apparatus may be held in the hand or be secured to a support 24, Fig. 2 (not shown) arranged to traverse the surface to be coated and to hold the spray or a suitable fixed angle to it.

Abstract: 1487888 Magnetic bubble memories TEXAS INSTRUMENTS Inc 25 Feb 1975 [25 Feb 1974] 7896/75 Heading H3B A defective minor loop in a magnetic bubble memory is marked by information contained in a corresponding minor loop in a "flag" memory. Detection of a "flag" bubble is used to cause data read-out from a deflective minor loop to be disregarded and/or to prevent fresh data being written-in. Batches of data memories with the same minor loop faulty are associated with a flag memory having a bubble inserted in the corresponding minor loop during manufacture. Alternatively a bubble may be inserted in the flag memory or an existing one annihilated according to changes in the state of the data memory in use. Since bubble propagation is effected by a common drive field the flag minor loops need only be of 1-bit capacity for flag and data bubbles to be simultaneously detected on respective major paths to which they are transferred from the minor loops in parallel. Plural data/flag memory groups may be processed in time division.
