Title: Improvements relating to milk-preparations or milk-products
IPC: A23C9/158
Filed: 1936-12-05
Abstract: Liquid milk preparations are obtained by mixing Vitamin C (ascorbic acid) with milk or a liquid milk product and thereafter, or during and after said addition, excluding air and harmful light as far as possible from the preparation until it is sealed in liquid form in containers in which the preparation is finally sterilized by heating. The milk or milk product treated may be raw milk or milk which has been pasteurized, homogenized, condensed or evaporated, or modified as to its composition.  The air may be excluded by maintaining the product under vacuum, and p  harmful light particularly ultra-violet and violet light by working in the dark or in red light only.  The ascorbic acid may be added directly to milk or may first be dissolved in a small quantity of milk or water.  Air and harmful light are preferably also excluded from the milk, to preserve its existing content of vitamin C before adding the ascorbic acid, or by pasteurizing and cooling it in closed systems and keeping it cold in a closed tank &c., or by keeping it under vacuum in a closed tank &c. The containers in which the milk preparation is finally sealed are light tight and the air space therein is kept as small as possible. In an example, a humanized cow's milk preparation is obtained by homogenizing the milk, the composition of which has been modified as required, at 3000 lb. per sq. in. at 145 DEG  F., cooling it down to 50 DEG  F. in a closed tank and exposing to a vacuum of 27 in. for an hour.  After relieving the vacuum, 1 1/2 ozs. of ascorbic acid are added to each 100 gals. of milk and a vacuum of 25" is established in the tank and the preparation gradually pumped out into tins or other light-tight containers which are filled as completely as possible, hermetically sealed and sterilized, e.g. by heating for 15 mins. to 240 DEG  F.  Harmful light is excluded as far as possible at all stages.

Title: Improvements in machines for rolling metal
IPC: B21B1/42
Filed: 1933-11-29
Abstract: 428,241. Rolling discs; taper rolling. SANKEY & SONS, Ltd., J., Albert Street Works, Bilston, and WILKINS, W. S., The Hollies, Hollies Drive, Wednesbury, both in Staffordshire. Nov. 29, 1933, No. 33428. [Class 83 (iv)] Rolls G are pulled radially along a segment of a disc Q or along a piece of plate to reduce it, the rolls being pressed together by top and bottom plates N, N<1> along which they roll, one plate N<1> being sloped when required to reduce the pass for tapering. The rolls G are mounted in a slide f reciprocated by a connecting rod C from a crank-pin d. The plates N, N<1> are also reciprocated at twice the speed by being mounted in a split carriage B, B<1> reciprocated by links f<2> from the same connecting rod C. On the idle stroke, (right to left), the rolls are not pressed together until the sloping toothed plate H<1> is stopped by the nut h<3> engaging the abutment J when the underplate teeth h slip under the first teeth, and thereby exert a pass-closing pressure on the rolls G. On the working stroke, left to right, this pass closing pressure remains or the pass is gradually closed by the slope N<1> to taper the work. At the end of this stroke the nut h<2> strikes the abutment J so that the teeth H<1> are held stationary while the teeth h slide under and spring up into engagement with them thus allowing the springs b<4> to open the pass in preparation for the idle return stroke. Hand actuated worm and screw-downs M fix the initial pass setting. The disc Q is indexed, by ratchet wheels and pawl, operated from the crank shaft, and makes two revolutions for one of the ratchet wheel, the second revolution being half a segment spaced from the first rolled segments to eliminate ridges. This is done by having one half-size tooth on the ratchet wheel and another 1¢-size tooth diametrically opposite it. A clutch lever 7 serves to start the machine and also on stopping actuates brake shoes 17 through toggles 16 to stop the driving shaft.

Title: Improvements in or relating to telecommunication systems
IPC: H04J4/00
Filed: 1965-08-06
Abstract: 1,105,916. Multiplex repeater. SIEMENS A.G. 6 Aug., 1965 [7 Aug., 1964], No. 33689/65. Heading H4R. Several telephone lines share a common repeater amplifier on a frequency or time division multiplex basis. Two wire lines may use negative resistance amplifiers, Fig. 4 (not shown), or hybrid transformers connecting a pair of oppositely directed amplifiers, Fig. 3 (not shown), while four wire lines use independent amplifiers for each direction of transmission. The multiplexers connecting any one line to the input and output of the amplifier operate from the same carrier or switching frequency source thereby easing stability requirements. Time division multiplex systems may use a normal pulse amplifier between the distributer switches, Fig. 9 (not shown), or a parametric amplifier as shown in Fig. 7 in which energy transfer takes place resonantly between a capacitor, e.g. C11, in one input line and the inductor Lp, with switches S11 and S2 closed, when all the energy' is stored in inductor LP, S11 and S2 are opened and a pulse on P3 reduces the value of inductor Lp so increasing the energy stored therein which energy, when transferred by closing switches S1 and S21, produces an amplified voltage on capacitor C21 of the corresponding output line. By varying the sequence of operation of the switches the energy transfer can take place in the reverse direction. Thus two-way transmission may take place if the switch sequence is changed during alternate cycles.

Title: Polyacrylic acid derivatives
IPC: B60G17/044
Filed: 1962-09-04
Abstract: Polyacrylic acid derivatives or their substitution products which are soluble or swellable in water can be obtained by heating polymer of acrylonitrile or copolymers or graft polymers containing at least 60% by weight of acrytonitrile to a temperature of at least 180 DEG C. preferably under super atomspheric pressure, in aqueous suspension dispersion in emulsion and if desired in the presence of an inert gas. Water-polymer ratios of between 10:1 to 1:1 and preferably between 6:1 and 3:1 are employed.  The hydrolysis may be effected in the presence of 0.1-3% by weight calculated on polymer of toluene-sulphuric acid. The resulting products can be isolated by spray-drying, by concentration by evaporation or by precipitation. In addition to acrylonitrile, the a -substitution products methacrylonitrile, a -chloroacrylonitrile and a -cyanoacrylonitrile may also be used. Particularly suitable as copolymer components are those which themselves give water-soluble hydrolysates for example, acrylic and methacrylic acid, the esters of acrylic and methacrylic acid, the esters or semi-esters of maleic and fumaric acid, vinyl esters, vinyl ethers, vinyl sulphuric acid and vinyl pyrrolidene. The product will form methylol derivatives and undergo cross linking with formaldehyde or with polyfunctional compounds, at the same time they will form salt and may be esterified by alcohols.

Abstract: 1392210 Magnetic bearings; vibration damping DORNIERGmbH 20 July 1972 [26 Oct 1971] 34033/72 Headings F2A and F2S [Also in Divisions B2 and G3]  In an ultracentrifuge having a magnetically suspended rotor 2 lateral positioning of the rotor within its housing 1 is effected by means of electrically controlled support systems in bearing planes such as I and II. As shown for plane I, the support system comprises electromagnetic coils 13 which co-operate with the rotor 2 and which are energized from controllers 12a, 12b in such a manner as to correct for any lateral deviations in the position of the rotor which occur, e.g. through processional or rotational motion, when the centrifuge is in operation. Sensors such as 11a, 11b are arranged mutually at right angles (Fig. 2, not shown), to detect the lateral deviations of the rotor which is thus effectively guided in two vertical planes also. The electromagnetic coils may be of annular form surrounding the rotor at each bearing location, or may comprise separate coils spaced around the periphery of the rotor (Figs. 2 and 3, not shown). The rotor may be of the multi-stage type sub-divided by flexible bellows, supported in several bearing planes (Fig. 4, not shown). The lateral support system may also be controlled to effect damping of any vibrations which may occur. The size of the gap between the vertical support magnet 7 and the top 6 of the rotor is maintained constant by correctively controlling the energization of the magnet in dependence upon deviation from a desired value set by a reference source 10, these deviations being sensed by a detector 8.
