Abstract: 423,679. Squeegees. WHEELWRIGHT, J. S., The Corner, Three Elm Lane, Tonbridge, Kent. Aug. 10, 1933, No. 22333. [Class 19] [See also Group XVI] A portable handoperated squeegee device for spreading liquid, semi-liquid, or granular substances over a flat surface by reciprocating motions of the device comprises two colour - spreading members such as squeegee blades 11, 12 which are movable into and out of operative position to function respectively on alternate strokes of the device, a controlling - member whereby the device can be reciprocated, and a connection between that member and the blades such that by a movement of the member at the end of each stroke the blade which will be the rear blade in the next stroke is moved into operative position and the other blade is moved into an inoperative position. The blades 11, 12 are fixed to a carrier 10, or are pivoted thereto to provide for angular adjustment. Hand-levers 13, 14 connected together and to a link 22 at 15 are connected by links 16, 17 to lugs 18, 19 on the lower part of a plate 20 detachably secured to the carrier 10, the link 22 being connected to a lug 23 near the top of the plate. When the device is pushed to the right, the links 16, 17 are pushed forward and the link 22 is pulled backwards, so that the carrier tilts to bring the blade 11 into operation, the tilting movement terminating when a stop 27 on the lever 14 engages the lever 13. In the reverse direction, the blade 12 is brought into operation and a stop 28 engages the lever 13. To relieve the stencil of the weight of the device when the stencil is raised off the printing-bed, a pin 30 carried by a vertically adjustable bar 29 is provided at each end of the carrier 10 so as to rest on the stencil frame, the pins rising off the frame so that the weight is taken by the stencil when the carrier tilts at the beginning of each working stroke. Similarly, rods 35 slidable in lugs 36 on the links 16, 17 may be adjusted laterally to rest on the stencil frame and take the weight of the levers 13, 14. A rail may be fixed to the stencil-frame to engage the pins 30 when the carrier is tilted so as to provide pressure on the blades ; also, the carrier may be loaded by weights placed on pins 26 upstanding from the plate 20.

Filed: 1969-12-03
Abstract: 1298800 Making semi-conductor devices SIEMENS AG 3 Dec 1969 [24 Dec 1968] 22655/72 Divided out of 1294889 Heading H1K A process for the manufacture of a semiconductor component having a semi-conductor body at a surface of which a PN junction emerges comprises the steps of treating the surface with an agent which removes any oxide skin present thereon and of simultaneously or subsequently depositing divalent lead ions on the oxide-free surface. The treatment to remove any oxide may involve the use of a liquid etchant (such as 40-50 wt. per cent aqueous sodium or potassium hydroxide; hydrofluoric acid; 1 : 1 hydrofluoric acid/fuming nitric acid; or hydrofluoric acid/bromine) or of a gaseous etchant (such as vapourized alizarin, vaporized aqueous hydrogen fluoride, or vaporized aqueous hydrogen fluoride/chlorine or bromine). The source of divalent lead ions is incorporated in the etchant, liquid or gaseous, and/or in a washing liquid used subsequently (and which is not capable of dissolving an oxide skin). Lead chloride may be vaporized into the gaseous etchant stream and lead acetate, stearate, naphthenate, or nitrate may be incorporated into either or both liquid etchant or washing liquid. The washing liquids may be based on water, ethanol, methanol or mixtures of these. The treated and dried body may be coated with a varnish or rubber containing a source of lead ions-suitable sources are red lead, lead carbonate, yellow lead oxide, or a lead carboxylate. In a specific embodiment the surface of a device is etched with 1 : 1 hydrofluoric acid/ fuming nitric acid, immediately washed with an aqueous solution of lead nitrate, dried, and coated with a hardened cyclohexanone solution of terephthalic acid, glycerol ester and phenylmethylpolysiloxane.

Filed: 1960-06-30
Abstract: 912,573. Automatic ship-steering control. WALKER & SON Ltd., THOMAS. June 29, 1961 [June 30, 1960], No. 22932/60. Class 38 (4). [Also in Group XXXIII] In a ship's automatic pilot, electrical signals derived from a compass control the steering gear through a pneumatic actuator utilizing a pressure below atmospheric derived from an internal-combustion engine propelling the ship. In Fig. 1 a ship's magnetic compass rotor 16 has transparent and opaque sectors 22, 23 so that if the course of the ship deviates in one sense from a heading determined by the setting of a photo-cell and lamp 18, 19, a solenoid 25 is energized through a relay 40 to move a pneumatic valve 27 to the position shown and thereby connect the underside of piston 44 of a pneumatic actuator 42 to a chamber 72 maintained at a pressure below atmospheric, so that the ship's steering wheel 13 is moved anti-clockwise to correct the course. De-energization of solenoid 25 when the ship deviates from course in the opposite sense allows valve 27 to fall under gravity and connect the upper side of piston 44 to chamber 72 so that the steering wheel is moved in the opposite sense. Alternatively, piston 44 may be moved in the opposite sense by a spring. The pressure in chamber 72 is maintained below atmospheric by its connection through a non-return valve 54 to the crankcase or induction manifold of a two-stroke or four-stroke internal-combustion engine 12, propelling the ship. The steering wheel may adjust the position of an outboard motor, or actuator 42 may operate an auxiliary rudder directly. Compass rotor 16 is provided with adjustable limit stops (not shown).
