Title: Improvements in or relating to the manufacture of semiconductor devices
IPC: H01L21/00
Filed: 1961-11-17
Abstract: 972,387. Semi-conductor devices. PHILIPS ELECTRICAL INDUSTRIES Ltd. Nov. 17, 1961 [Nov. 21, 1960], No. 41244/61. Heading H1K. Material is alloyed to the face of a semiconductor body by means of a jig which contains a first chamber for the body, a second chamber for retaining the material to be alloyed and a third chamber adjoining the body, so that after melting the material and tilting the jig, the material flows via a duct into the third chamber which is more than filled, the surplus material remaining in the duct. In Fig. 3, a germanium body 1 is located in a first chamber 12 in member 10 which together with member 11 constitutes the jig. A pellet of alloying material 23 is located in chamber 22 in member 11 which communicates via duet 21 to a chamber 20 adjacent the first chamber 12 and the surface of the germanium body. A second pellet 27 of alloying material is in chamber 26 which is connected via duct 25 to a small part of the surface of body 1. On the opposite side of body 1, alloying pellets 18 are located in chambers 17 which extend to a chamber 15 which adjoins chamber 12 containing the body 1. The jig is heated to melt the alloying material and then tilted so that the material is thrown on to the germanium body through ducts 21 and 25. The amount of alloying material in pellet 23 is more than sufficient to fill chamber 20 so that the residue remains in duet 21 forming a pimple on the flat surface of alloyed material which can be used for the attachment of a lead wire. The process is repeated and the jig rotated 180 degrees so that material in pellets 18 fills chamber 15 and contacts the surface of body 1; in this case also, excess material is provided to form a pimple on each of the alloyed areas. The jig may be of multiple form to allow for simultaneous treatment of a plurality of semi-conductor bodies. Silicon may be used in place of germanium, and the alloying material may consist of indium, lead, tin, bismuth with the addition of donors or acceptors such as antimony, arsenic, phosphorus, aluminium, gallium and boron. Specification 951,648 is referred to.

Title: A motor-driven typewriting office machine
IPC: B41J23/12
Filed: 1958-12-24
Abstract: 900,486. Typewriters &c. OLYMPIA WERKE A.G. Dec. 24, 1958 [Jan. 18, 1958], No. 41755/58. Class 100 (4). A device for producing a repeated striking action in a type lever machine comprises a drive drum 16 which actuates the intermediate type levers 5 through a drive rocker 15 having a roller 14 which moves a bell-crank 4 and a link 6. Depression of a key lever 24 by a key 24a acts through a releasing lever 25 engaging an arm 15c of the rocker 15 first to pivot the carrier lever 20 to lower the pivot 15d and then, by contact of a segment 15a with the drive drum 16, causes the type lever to strike. Finally, the lever 4 moves away from the roller 14 as coaction of the surface 15a and drum 16 is completed allowing a spring 22 to restore the lever 20, thus preventing repeated operation, even if the key lever 24 is still depressed, unless a hand lever 32 is released and allows a continuous-action lever 28 to be pivoted anticlockwise by a spring 33 so that its stop 28b is contacted by a nose 15e of the rocker holding it so that the return of the lever 4 acting on the roller 14 pivots the lever 20 clockwise and the surface 15a is re-engaged with the drum 16 to cause a repeat actuation. Release of the key lever 24 or restoring of the hand lever 32 moves the continuous-action lever 28 out of the path of the nose 15a and repeated striking stops. Specification 900,485 is referred to.

Abstract: 1,004,522. Drying pulses. UNILEVER Ltd. Nov. 18, 1963 [Nov. 19, 1962], No. 43744/62. Headings A2D and A2Q. In the preparation of dried pulses readily reconstitutable in water, pulses of high maturity (i.e. large peas having a defined Tenderometer Value greater than 110 and broad beans of sugars content less than 10%, stated to rehydrate less rapidly and completely than those of low maturity) are separated from those of lower maturity, and the pulses of high maturity are impregnated with a solution of hydrophilic material and are subsequently submitted to a drying operation. The pulses may be perforated before the drying of the pulses is completed, as described and claimed in Specification 783,974; such perforation is preferably carried out prior to the impregnation. The pulses are immersed in solutions at 90-95C. containing 15%-60% by weight of such hydrophilic materials as (i) sucrose and sodium chloride or (ii) glycerol, to provide a total amount of hydrophilic material in the dried pulses between 30% and 50% based on the dried weight of the pulses. A combination of hydrophilic materials possessing particular flavouring effects may be utilised. According to an example, a batch of peas having a Tenderometer Value of 125 was washed and separated into two fractions by a sieve having holes of 10.6mm. diameter. The fraction retained by the sieve being of Tenderometer Value 139 were pricked with pins of 1,25mm. diameter and, after blanching and rinsing, were soaked for 30 minutes in a solution, maintained at about 90C., containing 30% sucrose, 2% common salt, 0.2% sodium sulphite and 0.04% sodium carbonate. After this impregnation the peas were drained for 5 minutes and then airdried in a through up-draught drier to 30% moisture content by air at a temperature of 65C. and from 30% to 8% moisture content by air at 50C. The peas were rehydrated by cooking for 15 minutes in boiling water. Their total content of sugars was 41% on a dry solids basis. In alternative procedures (1) the soaking in sugar solution was carried out at 20 C. for 4 hours, (2) the peas were partially dried before the sugar impregnation treatment, (3) the impregnated peas were dried at a temperature within the range 110-160C. and (4) during the impregnation treatment the peas were subjected to two vacuum cycles of 10 minutes, each consisting of 1 minute to reduce the pressure to 725mm. Hg, 8¢ minutes at the reduced pressure and minute to bring the pressure back to atmospheric. A further example is directed to the drying of broad beans.

Abstract: 1,001,022. Measuring liquid flow rates. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Nov. 26,1962 [Dec. 11,1961; Feb. 23,1962], Nos. 44306/61 and 7244/62. Headings G1A and G1N. In a device for detecting the rate of flow of a liquid by measuring the time taken for a puff of foreign material to pass between two points at least one of which is a detecting point a number of sensing elements spaced apart in the direction of flow are provided at each detecting point. In the embodiment shown in Fig. 1 a puff of saline solution is detected at a first detecting point where the conductivity between electrodes 14 and 15 and between electrodes 15 and 16 is compared in a bridge circuit which also includes the secondary windings 18,19 of transformer 21 which has its primary winding connected to an A.C. source. The output signal obtained between the central electrode 15 and the A.C. supply is as shown in Fig. 3 the point 17 corresponding to the position at which the cloud 13 is symmetrically positioned with respect to the three electrodes. The electrodes may be of ring, line, or mesh construction and the outer electrodes 14,16 are preferably spaced apart by the diameter of the cloud 13 as it passes the detecting point this arrangement gives a definite reference point from which to measure times and as shown the point 17 is detected by an amplifier and phase-sensitive demodulator. In a system using one detector the detector output may be used to control the injection of more foreign material. In an alternative embodiment the foreign material is radio-active and two space detectors produce either a voltage or acount which is differenced to again produce an output as in Fig. 3. Each of the two detectors preferably compresses three separate detectors spaced around the pipe and connected so that their outputs are summed. The spacing of the two composite detectors is again of the same order as the length of the puff of material as it passes the detectors.
