Abstract: 1,052,005. Loom picking motion. RUTI MACHINERY WORKS Ltd. April 30, 1965 [April 30, 1964], No. 18400/65. Heading D1E. The picking stick 11 of a loom is supported at its lower end on the sley 66 by a pair of links 19, 20 whereby a substantially horizontal movement of the picker 15 is obtained, the link 19 being acted upon by a torsion spring (not shown) to bias it in the direction of the arrow A to effect the return movement of the stick 11 after a picking action by strap 12. A slide member 27 is pivoted on link 20 and has a sliding movement in bracket 18 on the stick 11 by virtue of a certain amount of play 28, the spring action on link 19 serving to take up this play so that when the stick is in its outer end position the lower end can move inwardly but not outwardly. Thus, when the returning shuttle 14 is caught by the picker 15 the lower end of the stick can move temporarily to the right by the amount of this play which prevents undesirable oscillations of the stick being set up by the action of the resilient receiving member 17 and check strap 30. In a modified arrangement, Fig. 2a (not shown), the pivoted lower link 20 is replaced by a member 33 rigid with the sley and having a wedge-shaped guide 34, 35 with which a member 31 on the stick co-operates. In the outer end position of the stick, spring action in direction A raises the stick and the member 31 from the guide 34, 35 to provide play 36 for the inner movement of the lower end of the stick as before. In another arrangement, Fig. 3 (not shown). bracket 18 is pivoted to the stick, and supported on links 19, 41, play 48 being provided between an abutment 49 on bracket 18 and the stick. In this device there is in addition a spring drum 52 on link 41 acting in a direction A to close the gap 48 through a strap 50 during the picking operation. In the outer end position of the stick however this action is prevented by a projection 53 on drum 52 engaging a stop 54.

Abstract: 1,053,105. Semi-conductor devices. INTERNATIONAL BUSINESS MACHINES CORPORATION. Aug. 18, 1964 [Aug. 19, 1963], No. 33635/64. Heading H1K. A plurality of PN junction devices are simultaneously manufactured by coating selected areas of a semi -conductor wafer of one conductivity type with metal, immersing the coated wafer in a melt saturated with said metal and containing also dopant characteristic of the opposite conductivity type, withdrawing the wafer with dopant combining material adhering to the coated areas, cooling, and then heating to form alloy junctions beneath the films. In a typical case pairs of holes 12, 13 (Fig. 3) are formed by photo-engraving in a film consisting of silicon oxide overlaid with glass (the method of making which is described) on a degenerate P-type germanium or gallium arsenide wafer. Gold, silver or, with germanium, copper is vapour deposited into the holes through an apertured molybdenum mask. After dipping in solder flux the wafer is slowly heated to 200 C. and then plunged into the melt. This contains a solid lump of the vapour deposited metal and consists of arsenic and tin, or arsenic, lead and tin if the wafer is germanium or of tin, tin-gold alloy, or indium or gold doped with tin, sulphur, selenium or tellurium if the wafer is gallium arsenide. After withdrawal from the melt and cooling, the wafer is reheated to 500-600 C. to form PN junctions beneath the holes. The metal residues are then etched away and replaced by evaporated gold contacts. which for use with germanium are doped with antimony. After annealing at 400 C. to reduce the peak currents of the resulting tunnel diodes the wafer is split into devices each containing one small and one large junction. The devices which may then be further annealed are used with the small junction forward biased.

Abstract: 1,054,646. Filters in series and parallel for liquids. PALL CORPORATION. March 9, 1964 [March 11, 1963; May 24, 1963 and Aug. 5, 1963], No. 9814/64. Heading BID. In the first embodiment two concentric pleated-cylindrial-sheet filtering elements are provided. Normal flow, (e.g. of hydraulic fluid), is in series inwards through the outer (fine) and inner (coarse) element to the outlet. When in response to demands on the system the flow rate is increased beyond a pre-determined value a flow control valve incorpoating a reciprocatable poppet with a Venturi orifice operates automatically to permit normal series flow to continue, but also to permit excess liquid to by-pass the outer element on its way to the outlet. The valve operates in the same way when, instead of increased flow rate, increased pressure difference develops across the valve on account of clogging of the fine element. (The valve is the subject of Serial No. Specifiation 1,054,647; attention is directed to the Division F2 abridgement). A snap-action disc valve is provided to permit liquid to by-pass the inner element on its way to the outlet when the inner element is clogged. By-passing of all liquid occurs on clogging of both elements. Magnetictype differential-pressure indicators are provided - one between the inlet and the region between the two elements, the other between the region between the two elements and. the outlet. . In a second embodiment, instead of the poppet valve two snap-action disc valves associated with a Venturi orifice are provided; these fulfil the same functions as the poppet valve. A third snap-action disc valve to by-pass the inner element, and differential-pressure indicators, are again provided. In this embodiment the filter assembly depends into, and discharges downwards into, a storage tank. In a third embodiment, instead of the poppet valve one snap-action disc valve and a set of narrow orifices in parallel relationship with it are provided. For by-passing both elements a snap-action disc valve is located between inlet and outlet. A single differential-pressure indicator between inlet and outlet is also provided Preferably the fine filter element is made of cellulose paper impregnated with epoxy resin and coated with a blend of glass fibres, diatomaceous earth and potassium titanate. Preferably the coarse filter element is made of sintered wire mesh having a surface of sinterbonded fine metal powder.

Abstract: 1,227,064. Acoustic measurement of temperature. CENTRE NATIONAL DE RECHERCHES METALLURGIQUES. 4 Sept., 1969 [6 Sept., 1968], No. 43818/69. Heading H4D. In a system for determining the temperature of a material (e.g. a steel bloom at more than 1000‹ C.) both longitudinal and transverse ultrasonic waves are transmitted into the material and their propagation times over substantially identical paths in the material are measured, the ratio of these times (and hence wave velocities) being a predetermined function of temperature. The propagation may involve reflection from a back surface of the material, or direct transmission through the material. At least one pair of adjacent transducers (one transducer for each wave type) is used, being coupled to the material via an air- or watercooled member forced against the material. This member may have a threaded surface to reduce parasitic reflections from its walls. The two wave types preferably have the same carrier frequency.

A multitubular assembly for hydraulic or pneumatic transmission of measurements and control pulses comprises a plurality of tubes 1, bunched and covered with at least one metallic sheath 3, corrugated and made of an elongate strip bent and welded longitudinally. The corrugations may be spiral, and the helical space 4 formed inside the sheath may be used to circulate an isothermal fluid to obviate any errors arising out of the effect of external temperature fluctuations on the tubes 1. The said space may instead be filled with a controlledpressure fluid so that the working pressure of the fluid in the tubes may be increased. The arrangement may be modified to detect damage to any of the tubes 1 as indicated by a change in the monitored pressure of space 4, which may be used to actuate a switch-off means. There may be two concentric sheaths, and the outer sheath may be provided with an insulating layer, e.g. a layer of synthetic resin formed by extrusion, or alternatively, the space between the sheaths may contain an isothermal fluid, as a means of preventing temperature fluctuations in the tubes 1. The tubes may be of copper or aluminium and may themselves be corrugated to impart flexibility to the assembly and increased surface area for heat transfer. The assembly may include a strip 2 of synthetic resin or metal foil to bind the tubes together.

Abstract: 1,230,461. Designing woven fabrics. INTERNATIONAL BUSINESS MACHINES CORP. 19 July, 1968 [23 Aug., 1967], No. 34431/68. Heading DIE. A digital computer and a display unit, Fig. 14, are used to generate a shedding pattern under the control of an operator using a light pen 28; the computer subsequently controls a card punching machine or a loom. An outline of the design is first drawn on the screen by means of the light pen. The computer analyses the design into discrete areas and allocates a reference number to each area (1, 2, 3, 4 on Fig. 14). By means of a key board 29 the operator selects a standard weave and indicates which area is to contain this weave by pointing the light pen at the reference number of that area (2 on Fig. 14). The reference number immediately disappears and an indication of the weave appears over the whole area; at this stage the outline of the area remains visible and the weave is represented by dots representing warp lifts. When the operator has chosen weaves for all the areas, th display is changed to the kind shown in Fig. 16, in which the outlines are deleted, and in which a crossing of wrap over weft is indicated by a vertical line, while weft over warp is indicated by a horizontal line. The operator can now inspect the junctions of the weaves to see whether excessively long floats occur. Thus at the right hand bottom corner of Fig. 16, where a 2/1 twill 52 meets a 5/1 twill 53, six consecutive warp ends cross over the bottom weft pick; by pointing the light pen at the crossing 58 and depressing a foot switch, the crossing can be converted to weft over warp.

Abstract: 1,250,195. D.C. to A.C. static inverters. DANFOSS A.S. 13 Aug., 1968 [29 Aug., 1967], No. 38615/68. Heading H2F. In a D.C./A.C. inverter, it is arranged that commutating capacitors C1, C2, Fig. 3, are always charged up before their associated load rectifiers ES2, ES4 are fired. Thyristors ES1, ES3 are first fired sequentially to charge up the commutating capacitors C1, C2, via R2 and R1 respectively, in preparation for subsequently effecting the turn-off of load current thyristors ES2, ES4. Thyristor ES2 is then fired and passes load current via a blocking diode E2 and choke L3 to an output point W. At the same time the charge on C1 is reversed by current flowing through ES2, diode El and a choke L1, and in addition ES1 is blocked. C2 also receives a supplementary charge, which will offset any leakage, by current flowing from L3 by way of diode E5 so long as thyristor ES3 remains conducting. ES1 is then fired whereby C1 discharges to turn off ES2. Thus a positive half wave of square waveform has been passed to the output phase terminal from the centre tap of L3. Immediately thereafter the load thyristor ES4 is fired and it passes, via diode E5, a negative half wave to the output terminal, a sequence as for ES2 being repeated. If the load is inductive, current continues to flow in the same direction after the conducting load thyristor is blocked. This current will flow through freewheel diodes E6 and E8 or E3, E 7 as the case may be, until it is reversed when the other load thyristor conducts. The firing pulse circuit as shown in Fig. 1, produces square waveforms b, b<SP>1</SP> in antiphase, from a null detector 1, which are differentiated at 4, 9 and fed to impulse transformers 10, 13 to produce firing pulses i 1 , i 2  for the quenching thyristors ES1, ES3. In addition, delayed pulses Z 1 , Z 2  to fire the load thyristors ES2, ES4 are derived from b, b<SP>1</SP> by first passing b, b<SP>1</SP> through delay circuits 5, 8 before differentiating at 6, 9.
