Title: Improvements in preserving organic materials
IPC: A23L3/16
Filed: 1919-01-24
Abstract: 142,169. Pape, R. Jan. 24, 1919. Preserving fruit and vegetables; preserving starch and gelatine; sterilizing milk.-A process for sterilizing food, such as fruit and vegetables, and other organic substances, such as starch and gelatine, but especially applicable to milk, consists in heating the substance to be treated while it is exposed to a pressure of one atmosphere or over of some appropriate gas. For milk, air or nitrogen may be used, but pure oxygen is not suitable. It is stated that milk treated by this method at temperatures between 70 and 98‹ C. lasts less well than milk that has been treated at temperatures either just below 70 or above 98‹ C., the process last described giving the greatest durability. To cause the milk to retain its odour and taste, rapid oscillations of temperature are produced during the process, either by forcing comparatively cold gas through the highly heated milk, or highly heated gas through comparatively cold milk, the pressure being maintained constant throughout the process by a loaded relief valve.

Title: Improvements relating to the production of mesityl oxide and its homologues from acetone and its homologues
IPC: C07C45/66
Filed: 1932-01-21
Abstract: The mixture containing diacetone alcohol or its homologues obtained by the action of an alkaline condensing agent on acetone or its homologues is subjected to the action of a weak acid, such as oxalic or phosphoric acid, in the presence of water, whereby mesityl oxide or a homologue thereof is produced.  For example, the mixture containing diacetone alcohol may be heated with the acid, the mixture of the vapours of water, acetone, and mesityl oxide being worked up continuously or discontinuously in a suitable manner; the acetone is preferably returned to the condensation stage.  Examples are given illustrating the condensation of acetone to diacetone alcohol, from which mesityl oxide is then obtained, and the condensation of methyl-ethyl ketone to the corresponding keto-alcohol, from which is obtained methyl-3-heptene-3-one-5.  An apparatus for use in the foregoing process has a stock container 1 from which acetone passes to the <PICT:0383474/IV/1> condensing towers 2, 3.  By means of a distributing device 4, the concentrated caustic potash circulated by the pump 5 is introduced into the tower 2 in the form of very fine droplets.  Into the mixing vessel 6 flow acidified water from a stock container 7 and the mixture of acetone and diacetone alcohol from the tower 3. The neutralized mixture runs into the reaction vessel 8 which contains some oxalic or phosphoric acid.  A mixture of vapours passes off into the column 9, the acetone distilling off to be liquefied in the condenser 11, while a mixture of mesityl oxide and water is drawn off at 10.ALSO:<PICT:0383474/III/1> The mixture containing diacetone alcohol or its homologues obtained by the action of an alkaline condensing agent on acetone or its homologues is subjected to the action of a weak acid, such as oxalic or phosphoric acid, in the presence of water, whereby mesityl oxide or a homologue thereof is produced.

Abstract: 987, 531. Automatic temperature control systems. BRITISH INSULATED CALLENDER CABLES Ltd. Jan. 16, 1964 [Jan.16, 1963], No. 2058/63. Heading G3R. The temperature of an electric blanket, of the type having a heating element physically associated with a control element of high positive temperature coefficient of resistance, is automatically controlled by an arrangement comprising a pair of back-to-back connected light activated silicon PN PN switches P1, P2 in series with the heating element terminals H1, H2 and its power supply M1,M2 these switches being maintained conductive by light from a lamp L so long as the resistance of the control element connected across terminals C1, C2 remains below a predetermined value corresponding to a certain light intensity. The lamp current is provided by a transformer T and is controlled by a transistor TR2, whose base is connected to a resistor chain comprising the control element and resistors R4, R5 so that increase in the resistance of the element produces a proportionate fall in the lamp current, the cut-off temperature at which switches P1, P2 operate being adjustable by the resistor R5. A fail-safe circuit comprising a transistor TR1, resistors R1 R2, R3 and a fuse F2 ensures that if an opencircuit occurs in the heating element the control circuit supplied by transformer T is de-energized. Transistors TR1, TR2 have the same characteristics, and the emitter voltage of TR2 is stabilized by zener diodes ZD1, ZD2.

Title: Torque Transmitting Device having Hydraulically Actuated Friction Plates and Torque Sensing Means
Inventor: HILPERT CONRAD ROTH
IPC: F16D25/02
Filed: 1968-01-15
Abstract: 1,179,516. Friction clutches; clutch control. TWIN DISC Inc. 15 Jan., 1968 [16 Jan., 1967], No. 2083/68. Headings F2C and F2L. In an hydraulically-actuated friction clutch D the fluid pressure is varied continuously in accordance with the driving torque so as to permit a variable amount of slip and produce a constant output torque. In the embodiment shown in Figs. 1 and 2 an input member A and a surrounding carrier E have interengaging segmental parts A1, A2, E3, E4 defining pairs of chambers 2, 2<SP>1</SP> and 7, 7<SP>1</SP>. Hydraulic fluid enters these chambers through a passage 1 and passes through a valve F and passage 3 to a chamber 4 defined by the end wall E2 of member E and a piston C carrying a clutch engaging flange C2. At a desired output torque the fluid pressure in chamber 4 maintains the clutch fully engaged but should the driving torque increase, relative rotational movement occurs between the members A and E causing an increase in pressure in the chambers 2, 2<SP>1</SP>. This results in the closing of the valve F thus stopping the flow of fluid to chamber 4. Since this chamber is vented to a sump via an orifice G, balance chamber 5 and passages 6, 6a of the clutch cooling system, a drop in pressure occurs therein resulting in clutch slip. The torque responsive chambers and the chamber 4 may be supplied with fluid independently through separate passages 1, 9 respectively. Fig. 4, in member A so that the pressure in chamber 4 is not dependent on the control pressure and adjustment of the output torque is possible. Passage 9 communicates with a passage 10 in member E and forms therewith a valve H which regulates the flow of actuating fluid on relative movement of the segment A1 and member E. Fig. 6 shows a modification of the single pressure system of Fig. 1 wherein the valve K can switch the fluid from passage 1 to either the chambers 2, 2<SP>1</SP> or 7, 7<SP>1</SP> as well as regulate the flow to passage 3 and chamber 4 whereby the clutch is controlled in either direction of rotation. The two-pressure system of Fig. 4 may be modified to provide bi-rotational control by providing extra passages and valve ports in the segment A2 and member E to convey fluid from passage 1 to either chambers 2, 2<SP>1</SP> or 7, 7<SP>1</SP>, Figs. 7 and 8 (not shown).

Abstract: 900,122. Rolling thin sheets or foil. CONTINENTAL CAN CO. Inc. Jan. 21, 1960 [Jan. 21, 1959], No. 2258/60. Classes 83 (2) and 83 (4). In a method of making thin wide strips, e.g. of steel, a billet 10 having an enclosed layer of stop-weld 11 is rolled to strip-form and the edges of the strip are removed by longitudinal slitting to separate the laminations into two thin strips 20, 21. Strip with thicknesses between 0.002 and 0.007 inches and with a width of not less than 30 inches are thus rolled in conventional cold-rolling mills. The billet may be prepared by casting or from hot-rolled slabs or coils. The strip may be annealed prior to slitting and after separation the thin strips are cleaned and coated with tin, lead or zinc or are electroplated. Alternatively, the thin strips may be enamelled and baked. Prior to electroplating or enamelling the strip may be slightly hardened and made smooth and bright by a ¢-2% cold-rolled reduction. In a modification, thin carbon steel strip clad with stainless steel on one or both sides is produced by first hot-rolling then cold-rolling a pack, Fig. 11, comprising stainless steel plates 50, 52, 53, 55 and carbon steel plates 51, 54, the plate 53 being recessed to accommodate stop-weld 11. More than two thin strips may be produced together by interposing further layers of stopweld. The stop-weld may be aluminium oxide, talc, graphite, salt or sugar. Aluminium oxide stop weld produces a mat finish.

Abstract: 555,493. Automatic volume control. STANDARD TELEPHONES & CABLES, Ltd., and SCULLY, C. T. Feb. 20, 1942, No. 2277. [Class 40 (v)] Amplified automatic volume control voltage is obtained from an alternating voltage source arranged in series with a controlled rectifier and a resistance. The control voltage is taken from the junction of the rectifier and the resistance and the rectifier is controlled by a rectified voltage derived from the signal. The Figure shows a diode detector 1 the voltage across the load 3 of which controls rectifier 5 connected in series with the resistance 6 and the source which may be a secondary on the mains transformer. The rectifier 5 may be inverted to produce a positive instead of a negative control voltage, Fig. 2 (not shown) and the signal diode may be reversed so that changes in the signal voltage will produce changes in the control voltage in the same phase instead of in reverse phase. The control voltage may be smoothed by resistance 7 and condensers 8, 9 or by a low-pass filter. A filter to exclude the signal may be interposed between the diode and the rectifier valve.

Title: Improvements in or relating to the moulding of resin impregnated materials
Inventor: JUDD NIGEL CECIL WILLIAM
IPC: B29C70/00
Filed: 1958-01-23
Abstract: A method of constructing an article of laminated components each including synthetic resin and fibrous material comprises joining together the components by overlapping and/or interleaving marginal portions initially left resin free, impregnating the margins with resin and curing the resin.  The resin free margins may be of differing widths and those of one component may be interleaved with those of the other whilst laid on a mould surface, resin then being applied and cured. Alternatively, the laminations of the two components may be complementarily staggered, the joint margins being overlapped so that the edge of a lamination of one component butts against the opposed layer of the other component and overlaps the butt joint of the next adjacent opposed pair; the joint is then the same thickness as either component.  The laminations may be of woven glass fibre and the resin a polyester.  The margins may be kept initially resin free by a process as described in Specification 898,776.
