Title: Improvements in or relating to strain gauges
IPC: G01B7/16
Filed: 1962-03-30
Abstract: 1,007,031. Semi-conductor devices. HONEYWELL Inc. March 30, 1962 [April 3, 1961], No. 12394/62. Drawings to Specification. Heading H1K. An element for a semi-conductor strain gauge comprises a crystal of high resistivity semi-conductor having a surface layer thereon highly doped with an N or P-type impurity substance, the surface layer thus having a comparatively low resistivity and having ohmic electrodes attached thereto at points remote from one another. Silicon, germanium, and other semi-conductors such as the intermetallic compounds may be used. Suitable doping agents include phosphorus, arsenic, antimony, aluminium, gallium, indium or boron. The surface layer may be provided by vapour diffusion techniques or, less desirably, by the direct alloying of electroplated or vacuum deposited films. The production of the particular embodiment starts with a silicon filament having a resistivity greater than 10 ohm. cm. and which is cut so as to have the (111) axis along the filament and so as to have a substantially square cross-section. After polishing the surface with a chemical etch, such as 1: 1 :1 H 2 O/HF/HNO 3  containing 1% by weight of silver nitrate, boron is diffused into the surface using known inert carrier gas techniques. To complete the element electrical contacts are made to the surface layer using an electroless nickel bath.

Abstract: 1454008 Light guides PIRELLI GENERAL CABLE WORKS Ltd 20 March 1975 [20 March 1974] 12467/74 Heading G2J An optical communications cable 1 (or 1a) e.g. as described in Specification 1453402) comprises a plurality of single-material optical fibres 2 (2a) (e.g. of the cross-section shown in Fig. 2) which are optically joined at their opposite ends to respective short lengths 18, 18a of cladded core optical fibres which project for insertion into a joint or terminal accessory. In Fig. 1, each of cables 1, 1a terminates in a circular metal end block which supports a capillary tube 8, 8a. The end of each single-material fibre 2, 2a is inserted halfway into one end of the capillary tube 8, 8a and the cladded core fibre length 18, 18a is inserted into the other end so as to abut the fibre 2, 2a and sealed by resin 19.  To join the cables 1, 1a together, a metal jointing accessory 14 is used which has a further cappillary tube 16 for receiving the projecting ends of the cladded core fibre lengths 18, 18a. The arrangement is such that when metal sleeves 22, 23 are screwed together, the portions of fibres 18, 18a within chambers 25, 25a are slightly curved under a compressive force. The chambers 25, 25a may be liquid filled.

Title: Improvements in or relating to the production of angel food cakes
IPC: A21D13/08
Filed: 1955-05-02
Abstract: In preparing angel food cakes, an anti-foaming agent is incorporated in amount insufficient to prevent the whipping of the egg white but sufficient to prevent excessive swelling of the foamed cake batter on baking and subsequent collapse of the cake on cooling.  For the purpose there may be employed a farinaceous ingredient having the requisite fat content, e.g. a flour having a hexane-extractable fat content of 0.2-0.5 per cent, such fat being present to 0.5-1.5 per cent of the dry egg white.  Examples are concerned with dry mixes, for incorporation of water, containing (i) starch coated with the fat extracted by ethanol from cake flour, dried egg albumen, starch, sucrose, cream of tartar and salt; (ii) dried egg albumen, cake flour and starch, sucrose, cream of tartar, salt, sodium hexametaphosphate, and calcium stearate as additional anti-foaming agent; (iii) flour from which the fat has been extracted with alcohol and returned in part, flour, dried egg albumen, hydrolysed soy protein, sodium hexametaphosphate, cream of tartar, coating sugar, dextrose, salt and calcium stearate; (iv) dried egg albumen, cake flour, ethanol extracted cake flour, sucrose, cream of tartar, salt, sodium hexametaphosphate and calcium stearate.  Other examples are concerned with two-package dry mixes, wherein the first packages contain dried egg albumen, coating sugar and sodium hexametaphosphate and the second packages contain mixtures of extracted and unextracted flour in varying proportion, sucrose, salt and cream of tartar; in use, the first package ingredients are whipped with water to a foam and the second package ingredients are stirred into the foam.
Patent GB-783762-A (GB)
Title: Recovery of phenolics from industrial wastes
IPC: C07C37/00
Filed: 1956-04-25
Abstract: Phenols are recovered from waste liquors containing a phenol and aldehydes by the addition of a bisulphite in sufficient amounts to react with all the aldehyde present.  The waste liquor at pH below 9.5, preferably 7-9.5 is treated to a steam stripping process, whereby the phenol volatilizes and the aldehyde is fixed as the bisulphite adduct.  The steam and phenol vapour are separated, e.g. by passing through aqueous alkali solution, whereby the phenol is absorbed from the mixture.  Prior to the addition of the bisulphite the pH of the waste liquor is preferably adjusted to 7\sB0.4.  After removal of the phenol the steam may be recycled together with any oil vapours which may be present.  The phenol recovered may be phenol itself or a homologue such as a cresol or xylenol.
