Abstract: 1327877 Valves MASCO CORP 2 Dec 1971 [9 April 1971] 56079/71 Heading F2V A hot and cold water mixing valve comprises a mixing chamber 13, Fig. 1, a cold water inlet 21, a hot water inlet 22, and a ported plastics disc 18 rotatable with a stem 16. The stem 16 carries a member 48 provided with two arms. 57 and 58, Fig. 2, which abut against an upstanding boss 47 of a bushing 19 to define a first position in which the inlet ports are both closed and a second, fully hot, position in which the hot water inlet port 22 only is open. As the disc 18 moves from the closed position, the port 33 therein, Fig. 4, first uncovers the cold water inlet 21 but is eventually moved out of alignment as the port 34 is brought into full coincidence with the hot water inlet 22. The water in the mixing chamber flows to the outlet over the edges of the disc 18. The fully hot position is adjustable by means of a screw 59 extending through arm 58. The bushing 19 can be turned through 180 degrees to adapt the valve for clockwise or anti-clockwise operation. Seats 27 are formed of rubber

Abstract: 579,753. Recovery of copper from composite metal plates. JENNINGS, H. W. K. (Crowell-Collier Publishing Co.). April 21, 1944, No. 7442. Drawings to Specification. [Class 82 (i)] A method of recovering copper from a copper plate having one relatively clean surface and, on its other surface, a coating of a metal that oxidises at a temperature lower than the melting point of copper comprises oxidising the coating of metal by directing a flame against the said clean surface of the plate, distorting the latter in a number of small areas to crack and loosen the oxidised coating, and removing the loosened coating. The Specification refers to the recovery of copper from printing plates composed of a base metal, for example an alloy of lead, tin and antimony, a plating of copper and a layer of nickel superimposed on the copper. The nickel is stripped electrolytically, a protective coating such as chalk or whiting is applied to the exposed surface and the greater part of the base metal is melted off, leaving a coating of oxidisable base metal on the copper plate. After oxidation of this coating, the plate may be sprayed with cold water before distortion to loosen the coating. The loosened coating may be removed by brushing the surface of the plate, cleaning the brushed plate with acid and washing with water.

Abstract: 1338075 Chucks MOOG Inc 9 Dec 1970 [16 March 1970] 58443/70 Heading B3B A machine tool comprises a spindle 23 having a tapered recess 30 for seating a tool holder H, and a device for releasably retaining said tool holder H in the recess, said device comprising a drawbar 39, connecting means 52, 53 for releasably connecting the drawbar to the holder in response to longitudinal movement of the drawbar relative to the spindle, biasing means 51 urging the drawbar to move in a direction to pull the holder H into the recess 30, and release means 42 for moving the drawbar in the opposite direction to cause the connecting means to disconnect the holder from the drawbar, the release means including means for holding the spindle against longitudinal movement while moving the drawbar in the said opposite direction against the biasing means 51 and being operative to cause the holding means first to engage the spindle to prevent longitudinal movement thereof and thereafter to move the drawbar relative to the spindle in the said opposite direction, said holding means including a slide 121 movable into a lock recess 46 in the spindle and having a cam surface 146, the release means further including a pneumatic piston 99 having a member 149 engageable with the cam surface 146 to effect such locking movement of the slide 121. The bias means 51 comprises spring washers that act on an abutment 50 to retract the drawbar so as to draw resilient fingers 60 of a slide 58 around a cam 63 to engage hooks 61 inside a lip 56 on the tool holder H. To release the connecting means the drawbar 39 is moved to lower the slide 58 so that the fingers 60 move past the stationary cam 63 and the resilience of the fingers 60 retract the hooks 61 from the lip 50 to allow removal of the tool holder H. Further movement of the slide 58 enables a sleeve 70 to eject the tool holder H. The tool holder grips a tool shank T by means of screw 33. A slot 35 in the hool holder H engages a key 38 in the spindle 23 to orientate the tool and provide positive drive. A guide spider having fins is fixed to the bottom of the cam 63 to guide the fingers into and out of a recess 54 in the holder H.

Abstract: 1,193,399. Terminal block. HEGO-ELECTRIC G.m.b.H. 10 Dec., 1968 [18 April, 1968], No. 58525/68. Heading H2E. An electrical connector or terminal block having a slab-like insulating body 1 and terminal 2 is adapted to be clipped on to a U- section rail or bar 12. For retaining the connector on the rail there is provided an L- shaped spring wire 5 having a longer arm 4 which is accommodated in a groove 3 and a shorter arm which is generally S-shaped and has an arcuate portion 8. The shorter arm projects into a recess 14 and its tip is retained behind a lug 9 so that portion 8 can be freely deflected. Portion 8 may be prevented from deflecting by a locking pin 15. The tip 7 of arm 4 is set obliquely to the plane of the two arms and rests behind a lug 6 and thus tip 7 is deflected, twisting arm 4 and imposing an initial loading on the spring which serves to retain the spring in the body. Before being secured to the rail, the groove 10 and portion 8 rest on flanges 11 and 13 of the rail. On application of pressure on the connector, portion 8 yields and engages under the flange 13. The connector may be removed from the rail by a laterally applied thrust.

Abstract: 1406470 Photo-electric apparatus INTERNATIONAL BUSINESS MACHINES CORP 20 Dec 1972 [4 Jan 1972] 58903/72 Heading G1A In an apparatus for monitoring irregularities on a periodically structured surface 8 in which a laser beam is scanned - from 2a to 2c - periodically across the surface to produce an interference pattern at a photo-cell assembly 9, the intensity of at least one order of interference is sensed. A laser beam is scanned across the surface 8, e.g. of a magnetic storage disc, by an oscillating mirror 5. For a disc of acceptable quality the machine markings on the disc will have a regular, periodic structure, Fig.2 (not shown) and the disc will hence act as a reflection grating. The assembly 9 is positioned such that the -1, 0, +1 orders of interference fall on photo-cells 12, 10, 11 respectively. A photo-cell 14 monitors scattered light, while photo-cell 13 receives the ¢ order of interference. For a regular surface structure the output from photo-cell 13 will be steady and relatively low, Fig.4, left (not shown). However, irregularities in the machine cut, Fig.3 (not shown) will produce a varying, relatively high output from photo-cell 13, Fig.4 right. The scattered light level output from photo-cell 14 will also be greater in the latter case. The entire disc surface is scanned either by rotating the disc or by rotating the optical system about the disc.

The cellulose may first be mercerized with alkali (e.g. NaOH), then washed and centrifuged. The resultant slurry is treated at 0‹ C. with an aqueous solution of cyanogen bromide plus enough NaOH to give a pH of 10 to 11. The product is washed with water, then with a buffer solution and combined with an aqueous solution of polynucleotide phosphorylase at 5‹ C. under nitrogen for 15 hours; the product is centrifuged and washed. Inosine diphosphate treated at 37‹ C. with the above insolubilized enzyme in the presence of unfractionated oligoadenylic acid and trisbuffer at pH 8À2 gives a solution of polyinosinic acid from which the enzyme may be removed by centrifugation and re-used. Polycytidylic acid may similarly be obtained.

Filed: 1972-12-21
Abstract: 1394380 Superconductors VARIAN ASSOCIATES 21 Dec 1972 [27 Dec 1971] 59173/72 Heading H1K [Also in Division H2] In a method of making a splice between two compound superconducting members 6 of the type described and claimed in Specification 1,262,994 the heating of the assembly of the two members 6 and the particulate splice precursor is carried out in an atmosphere containing a trace amount of an organic vapour. The atomic carbon diffused into the splice material during this process forms impurity sites which prevent premature flux jumps and hence reduce the possibility of quenching of the superconducting mode in operation. The trace of organic vapour present in the otherwise inert atmosphere may be obtained by bubbling a helium stream through an organic liquid or by introducing a gas such as methane to a helium stream. Alternatively a coating of an organic liquid such as xylene or carbon tetrachloride may be applied prior to heating, e.g. by dipping, painting or spraying.
