Abstract: 873,751. Insulators. GENERAL ELECTRIC CO. Ltd. Aug. 13, 1959 [Aug. 14, 1958], No. 26174/58. Class 36. An insulating bushing has a plurality of insulated leads passing therethrough, each connected at one end to a contact member, the contact members being partially encased in and insulated from each other by insulating material cast around them and secured to the end of the bushing. The leads may comprise an insulated steel rod 5 passing through the porcelain bushing 1 and surrounded by an insulated copper tube 7, the ends of both leads projecting past the bushing 1 and being externally threaded. At one end each lead is screwed and soldered into the foot 13 or 14 of a terminal 9 or 10 and the terminals are partially embedded in an epoxy resin body 18 cast around them. Sealing rings 17 prevent ingress of oil, and a sealing grommet 19 performs the same function where the insulating body 18 abuts the bushing 1. At the other end, an end-plate 20 is clamped against the bushing by a spring plate 22 secured by nuts 21 on the end of tube 7, followed by a spacer 23 and end-plate 28 secured by nuts 24 on the rod 5; the rod 5 and tube 7 thus transmitting clamping pressure to the insulating body 18. The bushing is mounted through a partition by means of a flanged member 2 provided with sealing rings 29. An alternative arrangement for five leads comprises four insulated copper rods surrounded by a brass tube disposed inside a condenser bushing within a porcelain shroud. Both arrangements are especially suited for leading through from the diverter switch compartment to the selector compartment of an on-load transformer tap changer.

Filed: 1926-10-25
Abstract: 267,035. Fitzpatrick, H. D., (Maatschappij tot Vervaardiging van Snijmachines Volgens van Berkel's Patent en van Andere Werktuigen). Oct. 25, 1926. Counter-scales; pendulum-weight apparatus. - An automatic or other weighing-apparatus is prevented from functioning if the apparatus is out of level by means of a pendulous member the lower end of which enters a hole in the weigh beam if the apparatus is level but fouls the weigh beam if the apparatus is out of level. The weigh beam 7 connected as usual to a pendulum resistant 16 carries a plate 6 provided with a hole 12. The extremity of a pendulous rod 3 pivoted on the indicator housing by a pin 2 projects through the hole 12. On the rod 3 is an enlargement 5 small enough to pass freely through the hole 12. If the apparatus is level the beam may oscillate freely without interference from the enlargement but if the apparatus is out of level the enlargement fouls the beam and prevents it functioning. A weight 4 on the rod 3 assists to maintain the rod in a vertical position. An arm 8 fixed to the rod and visible through a glazed opening 10 indicates when the apparatus is level.

Title: Improvements in or relating to matrix storage arrangements
Inventor: ACTON JOHN REGINALD
IPC: G11C17/06
Filed: 1964-06-26
Abstract: 1,106,079. Matrix storage device. PLESSEY. UK Ltd. 10 June, 1965 [26 June, 1964], No. 26625/64. Heading G4A. [Also in Division H1] A matrix storage device comprises a plurality of row conductors 13 and a plurality of column conductors 14 arranged to intersect each other, having storage elements comprising photoresistors 17 electrically connected between the row and column conductors at predetermined cross over points. The photo-resistor may be insulated over most or all of its length from conductor 14 by a layer of insulating material such as silicon oxide or may have a layer of material such as tellurium to form a diode with the photo-resistor, situated at one end remote from conductor 13. If no diode is present the photo-resistor is extended to contact the conductor 14 at the end remote from conductor 13. Preferably conductors of gold or aluminium are formed on a substrate such as glass by a vacuum evaporation technique, spaced apart layers of silicon oxide are evaporated on to the conductors, with possibly a small area of tellurium at one end, a layer of cadmium sulphide is evaporated or sintered on to the silicon oxide and tellurium or on to the silicon oxide and a portion of the conductor, and further conductors are evaporated in a direction normal to the first conductors. Data is stored by shining light through holes in cards the holes being situated adjacent photo-resistors. The drop in resistance produced enables a D.C. source supplied to the drive line (conductors 13) to be detected on appropriate sensing lines (conductors 14). The diodes are used to prevent unwanted feed back, alternatively the sense lines can be connected to low input impedance amplifiers. An address de-coder (Fig. 4, not shown) can be provided integrally formed with the store on the same substrate.

Abstract: 1303189 Orienting bobbins ZINSERTEXTILMASCHINEN GmbH 3 June 1970 [12 June 1969] 26740/70 Addition to 1201955 Heading B8S [Also in Division D1] A modification of the bobbin orienting apparatus of the parent Specification comprises feed mechanism for successively supplying bobbins to the aperture having a length less than the length of the bobbin and width greater than the greatest width of the bobbin with the longitudinal axis of each bobbin parallel to the longitudinal centre line of the aperture, and cam mechanism movable transversely to such centre line to contact a bobbin at or near its larger end and push it longitudinally of the aperture so that it falls through the aperture with the larger end leading. In the operation of the apparatus shown, with a slide 210 (carried by a thrust-rod 212) retracted by a spring 213, Fig. 3, supplied empty bobbins 201 descend as a stack in a feed duct 200 with the lowermost thereof resting on a blocking face 240 of a section 224 and restrained by a bar 233. When a solenoid coil 219 is energized and an armature 216<SP>1</SP> drawn therewithin, the slide 210 advances so that a lifting section 222 isolates the lowermost bobbin from the stack. If the bobbin rests on the face 240 so that its narrower end does not rest on the support intended for it (but could drop directly into a delivery duct 203 when this is opened) one of two advancing cam edges 245 adjacent to the wider end of the bobbin correctively urges the bobbin on to such support face; in any case, continued advance of the slide causes the appropriate cam edge 245 to shift the bobbin linearly (in the direction of arrow 232) until it is located above the near side of a drop aperture 225 which has meanwhile moved over the inlet aperture 225<SP>1</SP> so that the bobbin 201, with its larger end leading, drops into the duct 203. The slide advance is arrested by a stop (not shown), coil 219 is de-energized and the slide restored by spring 213 with the aperture 225<SP>1</SP> again blocked by section 224 which receives the next bobbin through the now unobstructed outlet from the duct 200 in readiness for orientation. The blocking section may be omitted if the base portions of the orienting chamber 202 at the sides of the aperture 225<SP>1</SP> can reliably support the opposite ends of the bobbin. According to another modification (not shown) the blocking section, not provided with an aperture 225, serves only to close and open the aperture 225<SP>1</SP>.

Filed: 1960-08-09
Abstract: In a modification or improvement of the process disclosed in the parent Specification for making polycrystalline silicon-iron alloy sheet having grains orientated in the (110) [001] texture the cooling of the casting of the alloy from about 1400 DEG  C. to about 1000 DEG C. is at a rate between 50 DEG  C. and 130 DEG  C. per minute which results in a fine dispersion of the manganese sulphide present in the alloy which retards normal grain growth during the final anneal and thereby enables a useful degree of crystal orientation to be produced.  The metal alloy of composition 3.27% Si; 0.026 S; 0.057 Mn; 0.004 C; 0.0090; 0.002 Ni and the remainder iron can either be cooled directly from the liquid state or from a temperature in excess of that at which the manganese and sulphur are normally in solution, i.e. 1300-1400 DEG  C.  Cube textures as high as 80% are obtained when the alloy cooled at the above rate is heat treated within the range of 925 DEG  to 975 DEG  C. for one half-hour.  Complete texture development can be obtained in five minutes if annealing temperature is raised to 1050 DEG  C. to 1100 DEG  C. Specification 845,167 also is referred to.
