Abstract: 680,395. Moulding transformer casings.  AMERICAN GAS ACCUMULATOR CO. Dec. 5, 1950 [Dec. 10, 1949], No. 29712/50. Class 87 (ii). [Also in Group XXXV] Apparatus for moulding a transformer casing from non-metallic material comprises metal mould members 84, 86 having confronting recesses which form a cavity to which the material is forced through sprue passages 126, 128 from recess 124 by pressure of member 134. Air escapes through vent hole 116. The transformer 18 is located in the cavity by four upstanding studs 92 and similar downwardly extending studs 96. Transformer leads 28, 30, 48 pass through passages formed by ridged grooves such as 106, 108 in the confronting faces of the mould, which clamp the leads against the moulding pressure. These, which are located by guide pins 112 which enter recesses 114, are also clamped by rings such as 70 to an insulating bar 66, mounted on transformer-core 12. Other clamping means in different transformers are described (see Group XXXV). The moulding material is such, e.g. a synthetic rubber or synthetic resin, that it bonds with or without adhesive to the cable sheaths. Where heat is needed to cure the moulding material the press platens 144, 146 are heated or the die blocks and pressure members may be directly heated. The transformer may be preheated. The holes left in the moulded casing by withdrawal of the locating pins are plugged with moulding material, air being removed through a fine hollow tube. A modified mould comprises three blocks which have recesses which co-operate to form the cavity in which the transformer is located. Part of the required moulding material may be packed round the transformer in the cavity in sheet or other form.

Abstract: 711,872. X-ray apparatus. RUZICKA, P. Dec. 28, 1951 [Dec. 28, 1950], No. 30333/51. Class 98(1) Crystals are oriented by directing a narrow beam of X-rays on to a crystal, the angular position of which is then adjusted, until a diffraction pattern is obtained on a fluorescent screen or screens indicating the required orientation. As shown, a frame 9 is rotatable by means of a handwheel 11 in a head 10, which slides, together with brackets 17, 18, on a rail 15. The crystal 3 is supported on the axis of rotation by a rod 4 fixed to a sector 5, concentric with fhe crystal and rotatable by means of a knob 5a to rotate the crystal about a fixed axis. A second sector (not shown) enables the crystal to be rotated about a second axis at right angles. A beam of X-rays, restricted by a diaphragm 1, produces a diffraction pattern on a fluorescent screen 16 mounted on bracket 17, beyond the crystal. If desired, a second screen, apertured for the passage of the X-ray beam, may be placed between the crystal and the X-ray source. The crystal is rotated about its two axes of adjustment until a desired orientation, as indicated by the pattern on the fluorescent screen or screens is obtained. The crystal may be mounted by bring- ing bracket 18 below it. This bracket carries a base 19 in which a stem 21 with a cup 20 is movable. The cup 20 is filled with melted solder and is raised until the crystal is partly 'immersed in the solder, which is then allowed to set.

Title: Process for the manufacture of a soft cheese
IPC: A23C19/076
Filed: 1948-11-24
Abstract: In a process of manufacturing soft cheese, skim milk is subjected to strong pasteurization sufficient to bring about a considerable reduction of the effect of rennet on same which is then coagulated in the presence of rennet and preferably with a small amount of acid starter, the amount of rennet being more than 10 per cent of the starter, and the resulting curd is pressed to remove whey and then subjected to a mechanical disintegration and mixing treatment, the resulting disintegrated cheese being adjusted to a predetermined increased percentage of fat by adding whipped cream or other fat emulsion of a foam-like character to the cheese mass and incorporating it into the same by mechanical working so as to obtain a product of cream-like consistency constituting a homogeneous mixture of all the three states of aggregation solid, liquid and gaseous.  As an example the milk is centrifuged and cooled to the curdling temperature, i.e., below 82.4 DEG F (28 DEG C) or above 113 DEG F (45 DEG C), rennet and acid culture p  (ordinary "lactic acid starter") are added the rennet being at least 10 per cent. of the starter, e.g., 10 grams of rennet and 20 grams of starter, and the temperature controlled so that curdling is effected in at least 6 and preferably 20-24 hours whilst the mixture is left standing.  The curd is pressed to remove whey and then subjected to mechanical working to form a uniform homogeneous mass.  Whipped cream or other emulsions of fat in which air or other gas bubbles have been incorporated and preferably containing a gelatinizing substance e.g. 1/2 per cent gelatine, gum tragacanth or alginate are added to increase the fat content.  Flavouring, sweetening substance, preserving agents and/or protecting agents e.g., anti-oxidants may also be incorporated e.g., hydroquinone, esters of gallic acid and low molecular weight alcohols e.g., 107 per cent of ethyl gallate.
