Title: Crips-type products
IPC: A23L19/18
Filed: 1975-05-12
Abstract: 1466018 Crisp-type products PROCTER & GAMBLE CO 12 May 1975 [13 May 1974] 19854/75 Heading B5A [Also in Division A2] Crisp-type products are made by sheeting a formulated dough, forming a series of parallel arcuate grooves and ridges on one surface only of the sheet, so that it can be handled more easily, subdividing the sheet, and cooking, e.g. by baking or frying so that a crisp-type product having grooves and ridges on both surfaces is produced. Suitable apparatus comprises a feed hopper 10, a pair of smooth mill rolls 14, 16, an embossing roll 18 having annular grooves therein, a doctor blade 20 for removing the sheet from roll 14, and a conveyer 22. The sheet is caused to adhere preferentially to the roll 14 by (a) causing roll 14 to rotate 5-50% faster than roll 16, (b) having the temperature of roll 14 10-100‹ F. higher than roll 16, or (c) coating roll 16 with a non-stick material. Instead of having a separate embossing roll 18, roll 16 may have a grooved surface. The dough sheet may be 0À005 to 0À1 inch thick. The grooves in roll 18 may be 0À03 to 0À08 inch deep, separated by 0À06 to 0À12 inch, and preferably having tapering sides. The dough may be made from potatoes, corn, wheat, oats, rice, soy, peanuts or sunflower seed, and may also contain condiments or spices, flavourings, vitamins, emulsifiers, antioxidants and colourings. The dough may be fried at 275-400‹ F. for 5-60 seconds.

Title: Safety device for hydraulic brakes on vehicles
IPC: B60T11/32
Filed: 1933-07-15
Abstract: 409,169. Safety cut-off valves. FRIEDMANN, L., and FRIEDMANN, M., (trading as FRIEDMANN, A.), 6, Am Tabor, Vienna. July 15, 1933, No. 20082. Convention date, Feb. 16. [Class 135.] A device for closing a pipe of a hydraulic brake system in the event of a serious leak in the pipe or in a brake cylinder connected thereto comprises a ball-valve in a downwardly bent part of the pipe or in a downwardly bent pipe connecting two pipes, the valve being seated by the flow of the liquid. In Fig. 2, a downwardly bent part 8 of the pipe leading from the source of supply to a brake cylinder contains a ball-valve 10 which has clearance in relation to the wall of the pipe and normally sinks to the position shown. If, in applying the brakes, the flow of the liquid is sufficiently rapid the valve is carried upwardly and if there is a leak reaches the seat 9. An enlargement 11 limits the movement of the valves during the return flow of the liquid. In Figs. 3, 5, the downwardly bent pipe 8 connects two main pipes branching from a common pipe 3 and has seats 9<1> for the valve 10. The parts 12<1>, 3<1> of the pipes are connected respectively above and below the valve seats. When the brakes are applied and there is a leak in one of the pipes, the flow of the liquid in the pipe 8 from the unbroken to the broken pipe carries the valve to the seat adjacent the broken pipe which is thus closed.

Title: Improvements in and relating to roll winding machines
Inventor: MACKIE JOHN PRINGLE
IPC: B65H63/036
Filed: 1952-08-11
Abstract: 721,785. Winding packages of textile fibres. MACKIE & SONS, Ltd., J. Aug. 24, 1953 [Aug. 11, 1952], No. 20211/52. Class 120 (2). The roll-like package of twisted textile product formed in a roll winding machine, which is mounted for movement into and out of frictional driving contact with a driving roller, is lowered into contact with the driving roller by positively-acting power-operated control means. In the machine shown, to start a wind, a lever 32 is depressed to turn a latch 28 against spring-pressure 30 to release an arm 24. This frees the package-supporting arm 12, which, through an arm 20 and pin 22, rests upon the arm 24, for moving downwardly. An eccentrically-mounted gear 34, carried by the arm 24, comes into mesh with a driving pinion 38 and is rotated thereby, positively moving the arm 24 downwardly and thus lowering the core 16 or roll 18 into contact with the driving roller 10. The core 16 or roll 18 is then driven by the roller 10 but the arm 24 descends until its end 26 comes against a stop 42 on a weighted and pivoted lever 52. The gear 34 is then driven out of mesh with the pinion 38. Should the yarn 44 break or become exhausted a detector lever 46 falls to turn a disc 54 and rotate the lever 52. The stop 42 is then released from the end of the arm 24 and the eccentric gear 34 is again brought into driving engagement with the pinion 38 to lift the lever 24 and so remove the roll 18 from the roller 10. As the arm 24 rises it re-sets the latch 28, and as the end 26 of the arm 24 engages the notch 58 of the latch, the gear 34 rotates out of engagement with the pinion 38. To ensure that the gear 34 and pinion 38 come clearly out of engagement at the end of a working cycle, co-operating spring-influenced V-shaped grooves and ribs are formed respectively in the gear 34 and on a bushing carried by the arm 24.

Patent GB-743401-A (GB)
Title: Method for the production of articles by moulding substances of vegetable origin under pressure and at elevated temperatures
IPC: B27N3/20
Filed: 1950-08-15
Abstract: 743,401. Moulding articles from woodwaste etc.; plastic compositions. RUNKEL, R., and JOST, J. Aug. 15, 1950 [Oct. 1, 1948; Sept. 7, 1949], No. 20276/50. Classes 70 and 87 (2). Moulded articles are produced by pressing, in a first stage, substances of vegetable origin which contain resin-forming groups and carbonyl groups at temperatures between 125 and 280‹ C. and pressures between 50 and 300 atms. to produce water vapour and volatile reaction products, and, in a second stage, reacting the material in the mould with the volatile reaction products of the first stage. The materials used include wood, e.g. veneers or sawdust, seeds, seed husks, stalks, and lignin from brown coal. The raw material may be first decomposed by biological means, e.g. by using fermenting agents. Weak acids, such as the lower aliphatic acids, may be added, or, if the material is too strongly acid producing, bases such as ammonium hydroxide may be added. Phenols, aldehydes, various plasticizers or hardeners may be added. Fillers such as clay, powdered glass, zinc oxide, mica, heather or lignin may be incorporated in the material to be moulded. Metal parts, such as hinges, fish-plates, dowels, plates, eye-pieces, wires, &c. may be incorporated in the articles during the moulding process. The whole process is carried out in a gas-tight mould which may be sealed by means of the raw material. Gases which do not take part in the reaction, such as carbon monoxide and carbon dioxide may be removed from the mould during the first stage of the reaction. Alternatively, gases capable of taking part in the reaction or their conversion products removed from the mould in the first stage of the same or a previous reaction may be supplied to the mould in the second stage. Preferably the water content of the starting material is adjusted to between 10 and 17 per cent. Heating of the material in the mould can be interrupted after the beginning of a constant pressure period when no more gases are evolved. Thereafter, the material is cooled. External pressure may be applied. The heating and pressure may be adjusted to maintain constant temperature and pressure at the desired values throughout the operation. The reaction may be interrupted after the first stage, the intermediate reaction product being powdered and then fully condensed in the final stage which may be an injection, casting, extrusion or compression operation. A compression mould suitable for the process comprises a heated plunger 17. Layers of shavings 8, 10, 12 are separated by metal plates 9, 11. The mould is sealed by means of compressed sheets 4, 6, 14, 16 obtained from a previous moulding operation. These sealing plates alternate with metal plates 5, 7, 13, 15.

Title: Electric musical instrument
IPC: G10H5/02
Filed: 1946-07-08
Abstract: 646,127. Electrical musical instruments. DEHN, S. G. (Central Commercial Co.). July 8, 1946, No. 20353. [Class 88 (ii)] In an electric organ, a master oscillator M1, Fig. 3, controls a cascade of multivibrators A to F which produce complex oscillations with fundamentals at octave spacings. Twelve master oscillators M1 to M12, Fig. 1, tuned to semitones of the highest octave of the instrument, control cascades A1 to A12 which provide complex oscillation for all the 61 notes of the keyboard. The parts of Fig. 1 should be arranged as shown in Fig. 4 (1C not shown). The oscillations are fed under the control of key switches to the control grids of twin triodes T1 to T10, each of which handles six consecutive semitones, except T10, which handles seven. The outputs on common conductors 116, 117 and 118 are of different quality. The pure tones accepted by the low-pass filters LP are connected to conductor 118, amplified by a valve T11 and fed to conductor X1. The output on conductor 116, the higher harmonics of which are reduced by condensers 14, is amplified by a valve T12 and is fed to conductor X2. The output on conductor 117 is rich in harmonics and is amplified by valve T13. The output of T13 is in part fed to conductor X3 and in part further amplified by valve T14 and fed through band-pass filters BP1 to BP5 to conductors X4 to X8. By operation of stop switches S1 to S11 the oscillations on conductors X1 to X8 can be fed singly or in combination to an amplifier 120 for reproduction on the loudspeaker 121. Tremulant. Control potentials are applied to the grids of master oscillators M1 to M12 from the anodes of valves in a control circuit V. Low-frequency oscillations may be applied to the grids of the control valves from an oscillator M0 producing periodic variations in the output of the master oscillators to cause a tremulant effect. The control circuit V and the oscillator are illustrated in Fig. 2 (not shown).

Title: Improvements in darning machines
IPC: D04B17/00
Filed: 1919-08-19
Abstract: 151,797. Sawtell, W. E. Aug. 19, 1919. Darning.-Yarn is spread by a carrier 5 from one to the other of a pair of guides 7<2> below the work, a rank of bearded needles 4 descends through the work, and a corresponding number of bars 7 move forward and push the yarn against the needles so that as the needles rise the varn is engaged by the needle beards. As soon as the yarn is so engaged, the needle beards are closed by means of a reciprocating bar and the needles rise through the work. On the next descent, the loops of yarn brought through remain above the work and around the needles. The next set of loops drawn up. are consequently drawn through the loops previously left on the surface. The thread-guides 7<2> and the bars 7 are moved forward by separate cams and are returned by springs. The shaft 28 carrying the cams is bodily adjustable so as to vary the field of movement of the bars 7. The work is fed by a spiked frame 51 which is given rising and falling and feeding movements by means of a cam-slot 53<2> on a bar 53 which engages pins on the feed frame 51. The U-shaped presser-foot 13 is pivoted upon the presser-bar 15 so that it can be swung forward when work is to be inserted in or removed from the machine. The presser is lifted positively during each feeding movement. The needle-bar is actuated through a connecting-rod 17 of adjustable length and the rod is connected to the lever 18 by a pin which is made readily detachable.

Title: Improvements relating to thermionic valve control circuits
IPC: G08C15/06
Filed: 1946-07-09
Abstract: 630,075. Valve circuits. SCOLES, G. J., and METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. July 9, 1946, No. 20508. [Class 40 (vi)] A gating valve is associated with two or more control valves which are controlled by voltages applied to their grid circuits to vary the cathode bias of the gating valve to cause it to pass or to cut-off signals applied to its grid circuit. The circuit is such that the gating valve only passes signals when all of the control valves are conditioned to render it conductive. Fig. 1 shows a gating valve V3, which is normally cut-off by the bias voltage developed across the cathode resistor R1 by the passage through it of the cathode current of one of the two control valves V1, V2. The three valves are arranged so that each control valve is capable of rendering the gating valve inoperative and that the gating valve conducts only when two given signals are applied simultaneously to the control valves. Fig. 3 shows an arrangement in which a. positivegoing sawtooth voltage from a time-base is applied to two strobing circuits comprising valves V4, V5 and V7, V8. Valve V4, which is normally cut-off by the voltage across cathode bias resistor R7, is rendered conducting and a negative-going signal as shown in curve a of Fig. 4 is applied to the grid of control valve V1. Valve V7, which is similarly normally cut-off, is rendered conducting, valve V8 is cut-off, and a positive-going signal as shown in curve b of Fig. 4 is applied to the grid of control valve'V2. Thus valve V1; which normally has a positive grid bias, is cut-off, the voltage drop across cathode resistor R1 is reduced and the gating valve V3 conducts at instant T1, the anode voltage dropping as shown in curve c of Fig. 7. Valve V2, which is normally cut-off by the residual negative charge on capacitor C4, is rendered conductive at instant T2 by the positive signal from valve. V8, and the gating valve is cut-off again at this instant. D.C. restoring diodes V9, V10 are connected between grid and cathode of each control valve.
