Patent GB-464694-A (GB)
Title: Improvements in and relating to the preservation of perishable articles and materials
IPC: A23L3/36
Filed: 1935-10-22
Abstract: Perishable materials such as meat, fish, fruit, vegetables, bread or other readily perishable foodstuffs are preserved by freezing rapidly by means of cold air at -15 DEG  C. or below and subsequently storing in a continuous air stream at -15 DEG  C. or below, the temperature difference between the air-streams during both freezing and storing and the cooling surfaces for cooling said air-streams being at most 6 DEG  C.  The air during freezing and storage has a relative humidity of 85-95 per cent which is maintained automatically by the cooling process used therefor. The temperature difference of 6 DEG  C. or less between the air and the cooling surfaces may be obtained by increasing, e.g. doubling, the area of the cooling surfaces.  A higher speed of flow of the circulating cooling air over the cooling surfaces may be used additionally to the larger cooling surfaces.  A part of the cooling surface may be used to support the stored materials.  The freezing chamber may also serve for the cold storage, cooling tubes being provided therein.

Title: Electric motor control systems
IPC: G05F1/42
Filed: 1948-11-11
Abstract: 655,922. Automatic voltage and current control systems. FOSTER TRANSFORMERS & SWITCHGEAR, Ltd., and JENNINGS, R. E. Nov. 11, 1948, No. 29303. [Class 38 (iv)] [Also in Group XXXVII] Tap-changing gear is operated by a reversible D.3. motor supplied by either one of two gasfilled grid control valves according to the amplified difference between a reference voltage and a voltage proportional to the voltage or current which is being maintained constant. The voltage to be controlled, applied at P6, P7, supplies the various control circuits by transformers T1, T2 and is also rectified by valve V1 and applied in opposition to the voltage across a neon stabilizer V4 to a cathode-coupled pair of amplifying valves V3a, V3b. The output appears across resistors R15, R16, the mid-point of which is earthed via a resistance R14 across which is a small bias voltage derived from rectifier D2. An increase or decrease in the current in valve V3b causes the potential of the free end of R16 to become positive or negative respectively with respect to earth, hence either valve V7 or V6 will conduct to run a reversible series motor with centre-tapped field, connected at P1, P2, P3, in a direction to correct the deviation. To prevent hunting, a differentiating network C12, R27 is added to the input circuit. The magnitude of the error signal applied to the amplifier V3 and hence the sensitivity of the control circuit may be adjusted by potentiometer R24. A relay S1 shunted by a delay circuit C4, R10 is energized by a pentode V5 to provide delayed switching of the rectifier anode supply. The circuit may be modified for constant current control or a current component may be added to the voltage control to provide a rising characteristic.

Title: Improvements in electric furnaces
IPC: F27D11/02
Filed: 1919-11-25
Abstract: 154,444. Erichsen, A. M. Nov. 25, 1919. Resistance furnaces.-In a furnace having resistance bars, free to expand or contract, arranged in the form of one or more grids above the charge, a slight reduction of pressure is maintained, to prevent condensation in the openings through which the bars enter the furnace. The charge may consist of copper, nickel, iron, aluminium, brass, or materials to be distilled. As shown, the resistance bars 10, which may be of carbides such as silicon carbide, pass loosely through refractory sleeves 16 in the furnace walls. The furnace may be tilted by worm gear so that parts of the charge may be brought nearer to the resistance. The trunnions may form axles for a pair of large wheels which thus support the furnace. In some forms, a hopper 17 is provided in the middle of the roof and between two parts of the resistance. Above the hopper 17 there may be a preheating chamber 12. A slight suction is produced in the furnace by providing an adjustable vent 14 in the cover of the hopper or of the preheating chamber for the vapours which may pass through the hopper or through outlets 15 in the furnace roof. In another form the hopper is arranged laterally and a separate vent pipe may be provided.

Title: Color-television signal-translating system
IPC: H04N11/14
Filed: 1951-12-18
Abstract: 708,088. Colour television. HAZELTINE CORPORATION. Dec. 18, 1951 [Jan. 10, 1951], No. 29630/51. Drawings to Specification. Class 40 (3) In a colour television system wherein there are generated a "monochrome" signal primarily representative of the brightness of the transmitted image and a " colour " signal primarily representative of the colour components of the image, the gain in the colour-signal channel is varied inversely with the amplitude of the " monochrome " signal, so that the colour components are accentuated when the reproduced image is of low intensity. The invention is described as applied to a " dot-sequential " type of system wherein the colour signal is transmitted as the modulation of a sub-carrier lying within the frequency band occupied by the " monochrome " signal, and may be effected either at the transmitter or receiver. At, for example, the receiver, the channel carrying the monochrome signal includes a detector which derives a gain-control signal which is applied to the " colour-signal " channel to control the amplitude of the modulated sub-carrier which is subsequently detected to derive the colour-component signals. In a modification the monochrome signal is passed through two parallel channels, translating respectively the lower-frequency and higher-frequency portions of the signal. The lower-frequency channel is used alone to derive the gain-control signal since this channel does not pass the modulated colour sub-carrier and the control exercised is consequently independent of the colour signals.

Abstract: 598,521. Wood floors. KAHR, G. Nov. 7, 1945, No. 29735. [Classes 20(iv) and 87(i)] [Also in Group XXIII] Wood floors are composed of boards formed by one or more rows of united wood blocks 1 having the grain running vertically, the boards being joined by fillets 2 glued in grooves in their edges, and the blocks in a row being united by these fillets or by a lamina, for example a piece of wood veneer 16, Fig. 6, extending along an edge, or by both. Each board may have a fillet at one edge and a corresponding open groove at the other, or boards with two fillets may alternate with others having two grooves. In the form shown in Figs. 3 and 4 the rows of blocks are united by fillets and by nailing them to a base board 6. Layers 8 of soft wood or plastic material between the rows allow for expansion, which layers may fill only the space above the fillets, as shown. In another form the fillets uniting the rows of blocks are omitted, the blocks being connected by gluing their abutting faces, and, to eliminate the effect of swelling in the longitudinal direction of the board, the transverse abutting faces are finely grooved. The boards are made by gluing together a number of laths of square or rectangular section, with or without the intermediate veneers 8, cutting the block so formed in a direction transverse to the longitudinal direction of the laths, grooving the edges of the boards so formed, and gluing the fillets in the grooves.

Title: Temperature compensator for a closed hydraulic system
IPC: F15B7/10
Filed: 1954-10-18
Abstract: 757,469. Telemotor system temperature compensators. BALLARD, C. U. Oct. 18, 1954, No. 29931/54. Class 69 (2). A temperature compensator for maintaining the volume of liquid in a dual line telemotor system substantially constant comprises two valves, each valve being controlled by a pair of pistons, one piston of each pair being subjected to the pressure in one line of the telemotor system, the other piston being associated with the other line, the arrangement being such that both pistons of a pair need to be actuated to open a valve to permit flow of liquid from the associated telemotor line. Conduits 10, 11 communicate with the lines of a telemotor system and with angular grooves 20, 21 in a member 12. Grooves 20, 21 communicate with ball-check valves 34, 35, and a body part 13 is provided and formed with four cylinders, of which cylinders 36, 37 are arranged opposite the apex of groove 20 and at an end of groove 21, and contain pistons 38, 39 which are consequently subjected to the pressures in conduits 10, 11. The other two cylinders are similarly arranged opposite the apex of groove 21 and at an end of groove 20. Should, for example, piston 38 be depressed by the pressure in conduit 10, an end of a spring 41 will be depressed and will actuate a lifter member 51 and thus lift the associated end of a teeter member 45, which is consequently rocked. The valve 34 thus remains closed. The telemotor system can therefore function normally. However, should both pistons 38, 39 be depressed due to an expansion of liquid in both lines of the telemotor system occasioned by an increase in temperature, lifter members 51, 52 will both be actuated to raise the teeter member 45 and unseat the ball valve 34, allowing liquid to flow from the conduit 10 past the valve and into an accumulator chamber 57. At the same time ball check valve 35 will be opened to permit flow of liquid from the conduit 11 to an accumulator chamber 56, but most liquid will escape from that telemotor line having the highest pressure at the time the ball valves are unseated. When conditions permit, the pressure of the liquid in the accumulator chambers 56, 57 opens valves 35, 34 and the liquid is restored to the system. A higher pressure is maintained in the accumulator chamber which received most liquid from the telemotor system than in the other chamber, and consequently its liquid will be returned, in advance of the other's, to the line which lost most liquid. The relationship initially established between an actuator and the motor of the telemotor system is thus restored.
