IPC: C30B31/14
Filed: 1969-10-03
Abstract: 1,244,069. Semi-conductor treatment. SIEMENS A.G. 3 Oct., 1969 [4 Oct., 1968], No. 48704/69. Heading H1K. Silicon wafers are heat-treated, e.g. impurity diffused, in an evacuated horizontally disposed quartz tube and are held out of contact therewith by a plurality of thin silicon rods lying parallel to the tube axis. In the apparatus shown the wafers are located between annular quartz members 3 which are in turn located axially by clock 5 and plug 2, and transverse to the axis by further annuli 9, 10. The arrangement is such as to allow peripheral movement of the rods. Silicon spacers 11-15 which, like the rods, are at least as pure as the wafers, are disposed at the ends of and at intervals along the stack. The apparatus can be used for gettering or for inward diffusion, e.g. of vaporous aluminium from a source 16.

Abstract: 1,105,645. Measuring impact velocity. C. B. ASSOCIATES Ltd. Jan. 25, 1967 [Nov. 18, 1965], No. 49088/65. Heading G1K. A device for measuring the velocity at which a body strikes the ground comprises a resilient axially symmetrical reed 4 having one end S mounted in a holder 6 the other end 3 of the reed being free to move in response to sudden velocity change, means 7 for damping movement of the reed, and means 10 mounted to surround the free end of the reed, and adapted to be permanently deformed by movement of the reed beyond a predetermined value. In the embodiment described the deformable means 10 is in the form of a metal foil washer with a central hole through which the reed 3 passes. Excessive movement of the free end of the reed caused by impact of the device with a surface causes the reed to tear the surface of the metal foil in the direction of shock and to some extent on the direction of rebound. The damping means is in the form of a block of resilient foamed synthetic plastics material which contacts the casing 1, and surrounds and grips the reed 4. Mounted on the end 3 of the reed is a weight 8 which determines the deflection of the reed in response to given velocity charge.

The granule core may comprise hydrolases (or other specified classes of enzymes) carried by a detergency builder salt particularly sodium tripolyphosphate, and a cohesive organic binder particularly a non-ionic detergent-active compound, prepared by condensation of ethylene oxide with an organic compound having a reactive hydrogen atom (specified). The plasticized resin coating, may comprise dextrin or alkali metal lignosulphonate plasticized by glucose, sucrose, urea, glycerol, ethylene glycol or diethylene glycol monoethyl ether. The granule core may be sprayed with an aqueous solution of the plasticized resin until a continuous film of solid plasticized resin is formed around the core, and any excess water is removed. A minor amount of a non-ionic detergent-active compound may be included in the aqueous solution. The core may be contacted with a finely-divided, inert anhydrous inorganic material, e.g. silica or talc, during the formation of the coating In Examples 1 to 3, an enzyme slurry consisting of protease from Bacillus subtilis with inorganic salts dispersed in a liquid condensate of ethylene oxide with a mixture of C 11 , C 13  and C 15  secondary alkanols, was atomized into non-friable, porous granular sodium tripolyphosphate. On to the granule cores thus produced there was atomized an aqueous solution containing yellow dextrin and glucose. A detergent composition was then prepared by mixing the granules with a detergent powder containing sodium dodecyl-benzene sulphonate, sodium soap, anhydrous alkaline sodium silicate, coconut monoethanolamide, sodium tripolyphosphate, sodium sulphate, sodium carboxymethyl-cellulose, sodium perborate, water, perfume and fluorescing agent. According to Example 10 the enzyme-carrying granule cores were prepared by extruding a plastic mass of a commercial protease concentrate derived from Bacillus subtilis, sodium chloride, dextrin and water.

Title: Improved phase lock loop

Abstract: 1,245,504. Automatic phase control systems. R.C.A. CORPORATION. 15 Oct., 1969 [30 Oct., 1968], No. 50733/69. Heading H3A. A phase lock loop comprises a controlled oscillator 72, an arrangement 80, 94 for producing at least two reference signals having different phases and an error signal producer 96-104, 146 for producing an error signal in response to the application of the oscillator output and the reference signals, the error signal correcting the output frequency at times corresponding to the coincident application of the oscillator output and each one of the reference signals to provide a more frequent correction of oscillator frequency. Each of the error signals produced at discriminators 96-104 is corrected at the reference frequency rate by an amount proportional to the frequency deviation at the time of correction. The individual error signals may be added up in a combiner 146 to produce a total error signal (Fig. 4, not shown). The embodiment of Fig. 5 (not shown) is basically same except for the discriminator circuits being replaced by sampler gates (178-186) so that the undivided output of the oscillator (162) is sampled by the reference signals which are submultiples of the desired frequency, the sampling gate including a store e.g. a capacitor for storing a value corresponding to the magnitude of output signal during sampling.

Title: Caravan roof support

Abstract: 1434998 Caravan roof supports QUEEN ANNE GARAGE Ltd 25 Oct 1974 [1 Nov 1973] 50801/73 Heading B7B [Also in Division E2] The raisable roof of a motorized caravan is supported by two of the illustrated devices, each of which comprises a pair of U-shaped frames 14 and 16 pivoted to the caravan and the roof and urged towards their illustrated extended position by a torsion spring 36. The spring tends to rotate two collinear axles 32 and 34 in opposite directions. Frame 14 pivots on axle 32; but is rigid with axle 34. The reverse is the case with frame 16. When the roof is raised by pushing from inside the caravan, the spring carries the frames 14 and 16 beyond top dead centre to the illustrated position in which the cross member 16c of frame 16 abuts the arms of frame 14 to hold the roof in its raised position. To lower the roof, the cross member 14c of the frame 14 is pulled between the arms of the frame 16. The roof then closes by its own weight which overcomes the force of the spring 36.

Abstract: 1342844 Selective signalling GAMONCALMET INDUSTRIES Inc 3 Nov 1971 [31 Dec 1970] 51116/71 Heading G4H Remote reading apparatus for interrogating and receiving information from a plurality of remote devices via a telephone network, reads a telephone number from a punched card, punches it into a second card and also applies it via a first shift register to the telephone network to access one of the remote devices, information returned from which is passed through the shift register and punched into the second card. Each remote device is a utility (e.g. water) meter with four wiper switches giving respective decimal orders of the meter reading. The decimal orders are taken in turn, each being converted into 2-out-of-5 form, inserted into a second shift register (under control of contents of this same register) and shifted out preceded by "010", the bits being sent in frequency-shift form to the reading apparatus via the telephone network. At the reading apparatus, of each 8-bit decimal order, the initial 0 is dropped and the other bits shifted into a third (7-bit) shift register, the "1" bits also being counted. The information is discarded if (a) a "1" reaches the last stage of the register before three "1"s have been received, or (b) if a fourth "1" is received after three "1"s have been received, or (c) if there are three consecutive "1"s. However, normally this does not happen, and the "1" in the "010" preamble, on reaching the last stage of the register, enables a code converter to convert the information from 2-outof-5 (-coded decimal) to binary (-coded decimal), the result being placed in the first shift register for supply to the punch. The first shift register is a series of four-bit latches, with an auxiliary shift register (having one stage per latch) for selecting a latch for access.
