Title: Improvements in hydraulic dynamometers, brakes and couplings
Inventor: BATHURST WILLIAM NEVILE
IPC: F16H41/00
Filed: 1952-09-13
Abstract: 736,975. Dynamometers. HEENAN & FROUDE, Ltd. Dec. 10, 1953 [Sept. 13, 1952], No. 23037/52. Class 106 (2). [Also in Groups XXIX and XXXIV] A hydraulic absorption dynamometer has a valve A, Fig. 1, in its fluid outlet B, the force necessary to move the valve A against the pressure of the.fluid in the dynamometer being obtained from a pressure generator K<SP>2</SP>. By controlling the pressure in the dynamometer the torque absorbed can be regulated. The rotor J of the pressure generator K<SP>2</SP> is mounted on a shaft driven at the same speed as or at a speed proportional to the speed of the rotary part of the dynamometer. Low-pressure fluid is fed to the generator K<SP>2</SP> through a pipe m<SP>1</SP> and the fluid pressure generated is conveyed by a. pipe m<SP>4</SP> through a needle valve N<SP>1</SP> to one face of a piston D coupled to the valve A. The fluid acting on this face of the piston D can be bled through a needie valve N<SP>2</SP> and pipes m<SP>5</SP> to the opposite face of the piston D, this opposite face of the piston D being also in communication with the low pressure fluid in the pipe m<SP>1</SP>. When the valve N<SP>1</SP> is fully opened and the valve N2 is fully closed the force on the piston D tending to close the valve A will be a maximum. By slowly closing N<SP>1</SP> and causing the restriction to the fluid flow through the valve N<SP>2</SP> to be correspondingly reduced, the force tending to close the valve A can be progressively reduced until it approaches zero. The valve N<SP>2</SP> and the pipe mB may be omitted if desired. Figs. 5 and 6 illustrate the construction of the needle valves N<SP>1</SP> and N<SP>2</SP>. The controlling fluid is caused to flow through sharp-edged ports P which are varied in effective area by moving a spindle N axially through screw means associated with a hand wheel n<SP>1</SP> or other means. Specifications 24949/10, [Class 106 (ii)], and 473,270 are referred to.

Title: Improvements in or relating to means for transmitting radiant energy such as light, and to apparatus for use therewith
IPC: A61B1/00
Filed: 1928-08-13
Abstract: 295,601. Marconi's Wireless Telegraph Co., Ltd., (Assignees of Hansell, C. W.). Aug. 13, 1927, [Convention date]. Copying-telegraphs.-An optical cable, Fig. 6, is formed of fused quartz, glass, or other transparent " conductors," Fig. 1, which convey light from one point to another in consequence of total internal reaction. The energy-density of the light may be varied by varying the cross-section of the conductors as shown. The optical conductors may be associated with a core 20, Fig. 5. As applied to a copying-telegraph transmitter the cable may be used to convey a portion of the image to be transmitted (such as a vertical section of a line of print) to a number of photoelectric cells controlling multiphase signalling apparatus, and the relative positions of the conductors may be interchanged so as to mutilate the picture for purposes of secrecy (see Fig. 6). Corresponding arrangements are adopted at the receiving station. Thus a cable 16, Fig. 7, comprising five optical conductors may terminate at 36 in a wireless or other transmitter or receiver and at 14 in a head which is moved axially, so as to scan vertical sections of a line of print, across a drum 30 which carries either the image to be transmitted or a photographic film. At the transmitting station the five conductors control five photoelectric cells (Fig. 8, not shown) the output of which after amplification controls, by means of make-and-break relays, five different low-frequency supply circuits which simultaneously modulate a wireless transmitter of the type in which the carrier frequency, which is piezoelectrically controlled, is eliminated by a pushpull modulator and one side-band is then filtered out. At the receiving station (Fig. 9, not shown) the signals are heterodyned with a frequency equal to or different from that of the original carrier, and after demodulation they control the brightness of five light sources, the light from which is conveyed by an optical cable to the photographic recorder.

Abstract: 1,192,364. Protective arrangements. TEDDINGTON AIRCRAFT CONTROLS Ltd 29 Aug., 1967 [26 May, 1966], No. 23567/66. Heading H2K. [Also in Division G3] In an automatic temperature control system for the electrically heated mats 2, 4 of an aircraft de-icing system (see Division G2-G3), means are provided to automatically switch the system off upon the occurrence of excess temperature or current conditions. In the system each of a plurality of solid state switches 28 includes a transformer 34 whose core is chosen so that its Curie temperature coincides with the maximum allowable temperature of the thyristor 40 and diode 42 forming the switch. The transformers 34 are coupled secondary to primary in a chain and normally transmit high frequency firing pulses for the thyristors from a source 44 to AND gates 32 forming part of the control system. Should any one of the switches 28 become too hot, there is no output from the chain, no third input to any of the gates 32 and hence no firing pulses for the thyristors. When the temperature of the overheated switch falls, normal operation automatically resumes. Should the current through any switch 28 exceed a safe value, a respective over-current sensor 26 switches the system off by providing an input to a protection device 24 controlling the pulse width modulator 22 of the temperature control circuit. The device 24 has a second input from an arc detector 20 which detects out-ofbalance currents in the three phases in known manner and controls the device 24 to switch the system off. The over-current protection arrangement is reset by switching the system "off" and then "on" again.

Title: Cooking of scrambled eggs
IPC: A47J27/16
Filed: 1978-05-30
Abstract: A container (26) is in sealed engagement with a lid member (28). A feed pipe (110) for steam and/or air protrudes into the container (26) and the eggs to be cooked. Flows of steam, with or without compressed air, flow from outlet apertures (114), located at different places, of the feed pipe (110) into the eggs to be cooked. The duration of steam flowing in is 6-12 seconds. During this time, the eggs are stirred, heated and cooked. In the lid member (28) there is a venting line (56). The latter communicates via an annular aperture in the cover plate (88) with the interior of the container (26). The cooking thus takes place under ambient pressure. An impact plate (130) is connected to the feed pipe (110). This prevents splashing during the supply of steam. Provided in the container (26) is a free expansion space (70). In 6-12 seconds, small batches of scrambled eggs can be cooked which are identical to those cooked on a hot plate for a much longer time. <IMAGE>

Title: Improvements in or relating to protein food products
IPC: A23J3/28
Filed: 1963-06-17
Abstract: In making a protein food simulating natural ground or chopped meat, spun edible protein fibres are impregnated with an additive comprising a binder, a flavouring agent, a colouring agent, an oil and/or fat and/or an emulsifier, then heated, e.g. in steam or by broiling, baking or boiling in water, to set-up the fibres and then ground or chopped and lightly (partially) fried or lightly fried and ground or chopped.  The fried food may then be dried. The protein food may contain fried and unfried ground impregnated fibres.  Frying may be effected by partly or completely immersing the set-up fibres in cooking oil or fat at a temperature between 250 and 450 DEG F. The protein in the fibres may be a vegetable protein such as soy, safflower, maize, peanut or pea protein or an animal protein such as casein.  The binder may comprise a heat-coagulable protein such as dried egg albumen and, if desired, toasted defatted soybean flour, fresh wheat gluten and hydrolysed vegetable protein.  The flavouring agent may comprise meat, e.g. beef, flavouring monosodium glutamate, sodium chloride, yellow onion powder, brown sugar and spices.  The colouring agent may be a red dye and liquid smoke.  Specified oils for use in the additive are: soybean cotton seed, maize, coconut, palm kernel, olive, peanut, sesame, safflower and cod liver oil. Specified fats are butter and tallow.  The oils and fats may be hydrogenated.  Specified emulsifiers are: mono- and di-glyercides of stearic, palmitic and oleic acid, sucrose partial palmitate or oleate, dodecyl glyceryl ether sulphates, monostearin phosphate, glyceryl lactopalmitate and polyoxyethylene ethers of sorbitan monostearate and distearate.  The fibres may be spun by extruding a dispersion of the edible protein, in water containing 5 to 10%, by weight, of dissolved sodium hydroxide, through dies or spinnerets into an acidic coagulating bath and then neutralized to a pH value between 4.0 and 7.0, e.g. in an aqueous solution of an alkali or alkaline earth metal sulphite or bisulphite.  The fibres may be stretched to elongate them by 50 to 400% and allowed to age, e.g. for at least one week, before being neutralized. They may be heated and/or treated with a peroxide, such as hydrogen peroxide, to improve their flavour.  Alkali and alkaline earth metal sulphates and bisulphites may be added during or after impregnation of the fibres to tenderize them.
