Title: A New Device for the Weaving of Cloth Hearthrugs & the like.
Inventor: PARKER ROBERT TAYLOR
IPC: D03D41/00
Filed: 1918-01-28
Abstract: 122,491. Parker, R. T. Jan. 28, 1918. Pile-fabric looms; hand-power looms.-A hand-power or ordinary weaving-loom with a top-swing lay is provided with means for inserting out pieces of cloth or tabs in the warp for weaving hearthrugs &c. and comprising a series of boxes for holding the tabs and series of grippers with spring or lock jaws co-operating to take the tabs from the boxes and insert them in position. The tabs are placed in boxes arranged on the lay above the warp and across the loom, the boxes being formed by plates A held by wire supports, and the tabs are pressed upwards against spiked wheels C by guided supports E connected by springs D to a bar F, which is raised by cords and weights to keep the tension of the springs D constant. The wheels C are mounted on a shaft rotated by hand or other. wise at the proper time to project the top tab from each box, so that it enters the open jaws of a corresponding gripper H'. These grippers are mounted on a rotary beam, and the pivoted jaw of each is connected by a rod to a spring-pressed bar, which is moved against the spring action by cams L operated by levers L<4> and a hand-bar L<3> to close the jaws, means being provided to lock the jaws when open and closed. The closed grippers are then rotated through 90 degrees about their longitudinal axes by a perforated slide engaging levers on the grippers. Pinions K<3> on the ends of the rotary beam engage slidable racks K<2> and stationary racks K<1> on the lay, so that, when chains K<4> connected to the racks K<2> are released, the racks K<2> are lowered and the beam is rotated and lowered to cause the free ends of the grippers to point downwards towards the warp N. A second series of grippers H<2>, similar to the grippers H<1>, are then moved by a hand-actuated or other fork P along slide rods T so that their open jaws enclose the ends of the grippers H'. The rods T can be inclined upwards and downwards by pivoted bars S having sockets through which the rods T pass and operated by eccentrics Q, against which they are pressed by springs R connected to the rods T. The open jaws of the grippeps H<2> are moved downwards and then closed to secure the tabs and locked. Certain threads of the warp N are then raised, and the grippers H<2> are turned axially through 90 degrees to place the tab ends under the raised warp threads. Grippers H<3> are then advanced to seize the loose ends of the tabs at the other sides of the raised warps, and the grippers H<1> are released and returned to their initial positions. The grippers H<2>, H<3> are moved back, drawing the tabs into the weaving position, the grippers H<2> are released, and the grippers H<3> raised to set the tabs evenly, and then released in turn. The ordinary weaving is then resumed to secure the tabs into the rug.

IPC: H02P7/34
Filed: 1935-01-17
Abstract: 450,176. Exciting dynamo-electric machines ; electromagnets. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London. Jan. 17, 1935, No. 1624. Convention date, Jan. 17, 1934. Addition to 370,532. [Class 35] [See also Group XXXVII] In a system for controlling the variation of the magnetism of an electromagnet, or the field winding of a generator G, according to the parent Specification, an additional voltage source is connected in the circuit of the armature 2 of the auxiliary machine, and acts in such a sense as to accelerate the change in excitation. The additional voltage source may comprise a voltage dividing resistance 5, as shown, a battery, or a generator. A controller 9 controls the direction of excitation of the field winding, and the direction in which the additional voltage acts by means of interlocked reversing contactors 6, 7, and the field circuit is completed through a resistance 4 by a contactor 8 also under the control of the controller 9. With the field fully excited and the controller in position 2, the field may be reduced by returning the controller to position 1, and then back to the off position. A sudden reversal of the fully excited field is prevented by controlling the contactor 8 by a time relay, or in dependence on the excitation current. Alternatively, the excitation current may control an electromagnetic locking device on the controller.

Title: Improvements relating to indicating panels
Inventor: CAMERON JAMES BRISBANE
IPC: F21V8/00
Filed: 1956-01-19
Abstract: In the production of an aircraft instrument panel (see Group XIX) the surfaces of a sheet of acrylic resin are pre-treated by immersion in a solution of a strong reducing agent, e.g. 10 per cent stannous chloride in water, for ten minutes.  Several stock solutions are prepared as follows: Solution A.  Cane Sugar 100 grms.  Nitric Acid (S.g-1.22) 5 cc. Alcohol 200 cc.  Water to produce 1 litre.  Solution B.  Silver nitrate 10 gms.  Water to produce 1 litre.  Soluttion C. Ammonia solution (S.G.-0.880) 200 cc.  Water to produce 1 litre. Solution D.  Potassium hydroxide 10 gms.  Water to produce 1 litre. From these solutions the silvering solution is prepared by taking 200 cc. of the solution B and adding solution C drop by drop until the brown precipitate first formed just redissolves.  An addition of 10 cc. of solution D is now made which again causes precipitation.  This precipitate is again redissolved by addition of the minimum amount of solution C avoiding excess.  To this prepared solution 10 cc. of solution A is added.  The pre-treated acrylic sheet is now washed in water and immersed in the silvering solution for from 5 to 15 minutes to deposit a thin silver film.  This film is reflecting and also electrically conducting so that its thickness can be increased by electro-plating from an aqueous silver cyanide solution in a known manner.  The reflecting layer is then covered by a layer of black nickel plate also by electroplating in a suitable solution (see Group XXXVI).  Metals other than silver may be used for the inner reflecting layer of the metallic coating 15, for example aluminium, nickel, rhodium, and copper.  Nickel may be deposited chemically, whilst aluminium, silver and rhodium may be deposited by vacuum-metallizing.  In an alternative method of producing the panel the surfaces and edges of the acrylic sheet are first sand blasted and an inner layer of silver or copper two millimicrons thick is then applied by vacuum deposition.  An opaque layer of copper 0.0005 inches thick is then electrically deposited on top of the inner layer and an external coat of paint is finally applied.

Title: Semiconductor diode with improved high voltage characteristic and method of production thereof
IPC: H01L31/117
Filed: 1967-01-13
Abstract: 1,108,870. Semi-conductor radiation detectors. UNITED STATES ATOMIC ENERGY COMMISSION. 13 Jan., 1967 [8 March, 1966], No. 2050/67. Heading H1K. The nuclear particle and radiation detectors described are made of lithium drifted silicon. That shown is made by diffusing lithium into the entire area of one end face of a P-type silicon body to provide an N-type zone 22 which is used as the source for the ion drifting process producing high resistivity layer 13. At this point the perimeter of the N-type zone 22 is etched away. The drifting process is then continued to produce the central main portion 41 of the high resistivity body which is surrounded by an annular P-type region 11 of comparatively low resistivity. Drifting contacts may be lapped and etched away and gold contacts provided to the mesa and lower face of the body. The-high resistivity shelf is fully depleted during use of the detector to eliminate surface currents. A generally similar embodiment, Fig. 7 (not shown), differs in that the high resistivity shelf is also carried some way down the side of the body. Production of this device starts with the diffusion of lithium into the top surface and part of the side of a P-type body, but is otherwise the same as that of the embodiment described.
