Title: Apparatus for controlling, indicating and/or recording the value of a variable condition
Inventor: KUBIN MIROSLAV
IPC: G01F1/38
Filed: 1957-04-05
Abstract: 863,811. Fluid-pressure servomotor control systems. REGULA-VYVOJ NARODNI PODNIK. April 5, 1957, No. 11210/57. Class 135. In apparatus for controlling, indicating and/or recording the value of a variable condition an input signal bearing a non-linear relationship to said variable condition (e.g. a flow) is fed to a bellows 2 which through a lever 8 and a cam 1 moves a pivoted baffle lever 5 relatively to a nozzle 6 the back pressure is amplified by a relay 7 the output signal of which is fed to the output line 10 and, via line 3b, to a feedback bellows 3 acting on the lever 8 at the end opposite to that at which the bellows 2 acts. The cam 1 is profiled to effect square-root extraction. The baffle and nozzle may be replaced by a slide or needle valve. It is suggested that the input and output signals may be electrical in which case solenoids would replace the bellows.

Abstract: 927,298. Indirectly-heated cathodes. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. March 5, 1962 [March 28, 1961], No. 11333/61. Class 39 (1). The heater 2 of an indirectly heated cathode is spaced from the emissive sleeve 1 by a cored spacer 3 of refractory insulating material in the form of an open helical coil embracing the heater, which spacer is shaped to have a protuberance 4 helically circumscribing its surface. The spacer may be formed by overwinding a tungsten core 5 with a molybdenum wire, and forming the overwound core into a helix, which is then coated with insulating material by electrophoresis, dipping or spraying followed by sintering. The molybdenum overwinding may then be removed by etching in a bath comprising equal parts by volume of concentrated nitric acid, sulphuric acid and water, to leave a hollow protuberance. Specification 847,019 is referred to.

Abstract: 1,207,921. Toothed gearing. PRECISION ELECTRONIC COMPONENTS Ltd. 4 March, 1969, No. 11399/69. Heading F2Q. [Also in Division H1] In a miniature rotary variable resistor or potentiometer in which a contact 53 is moved by a spur gear 40 driven by a worm gear 25, the spur gear is constructed such that once it has reached the limit of its movement a portion of its periphery (e.g. a pair of spaced curved resilient limbs 46, 47) will resiliently flex in a radial direction to accommodate continued rotation of the worm gear without damage (see Fig. 3).

Title: Improvements in or relating to the preservation of fresh fruit, vegetables and like food materials
IPC: A23B7/00
Filed: 1926-05-01
Abstract: 271,626. Haddan, A. J. H., (Collins, F. D.). May 1, 1926. Preparing flour and meal from special materials. -Fresh fruit, vegetable, and like food materials are preserved without destroying their vitamine contents by drying, slicing, then chopping to break up the tougher fibres, and grinding to reduce the fibres, seeds, &c., to minute form and to produce a compact mass in which the oils, fats, cellulose, mineral salts, starches &c., are evenly distributed. The mass is then ground more finely to break up the cell further, and is pressed into the desired shape. The grinding is stated to release a natural preservative which, when the pressed mass is exposed to air for a short time, causes the formation thereon of a film which, with the density of the mass, prevents the entry of air or insects and allows the product to be kept indefinitely. The preliminary drying is carried out at not above about 180‹ F. and until the moisture content is below 25 per cent. The process is said to be applicable for the preservation of dried fruit such as apricots, prunes, peaches, pears, and apples.

Title: Improvements in or relating to the treatment of coal with solvents
IPC: C10L1/04
Filed: 1930-04-11
Abstract: In making solutions of coal as coal to obtain coal products as described in Specification 268,372, [Class 91, Oils &c.], the solvent power of the oils and tars specified is increased by dehydrogenating them by treatment with sulphur or/and oxygen either prior to or during treatment of the coal.  Condensation aids such as zinc chloride, aluminium chloride, potassium hydrate, and metal oxides, may be present.  The products may be more or less freed from sulphur in any manner, e.g. by heating to higher temperatures in an autoclave and allowing the hydrogen sulphide formed to escape.  For example, water-gas tar or low-temperature carbonization tar is refluxed with 10 per cent by weight of sulphur for about 6 hrs.; when evolution of sulphuretted hydrogen ceases 20 per cent of fused zinc chloride is added and refluxing continued for about 9 hrs.  The tar is then separated from the chloride, and used as solvent.  It is stated to be less viscous, of better colour, and lower sulphur content, and of greater solvent power for coal than the original tar.  Or 80 lb. of tar, 8 lb. of sulphur, and 20 lb. of coal are heated to 320 DEG  C. in a rotating autoclave until the pressure ceases to increase; the autoclave is allowed to cool to below 200 DEG  C., the hydrogen sulphide allowed to escape, and the coal solution discharged.

Acidic condensing agents specified are boron trichloride, sulphuric acid, stannic and titanic chlorides and particularly boron trifluoride and its diethyl ether complexes the latter compounds being used in amounts of 0.0001 to 0.1, preferably 0.0025 to 0.01, mol. per mol. of acetal. Temperatures specified are 0-100 DEG  C., preferably 0-50 DEG  C. with pressure if necessary to maintain a liquid phase.  In the above formula the value of n depends on the ratio of acetal to vinyl ether used, e.g. 1,1,3-trimethoxy hexone is the main product when methyl vinyl ether and the dimethyl acetal of butyraldehyde are reacted in the mol. ratio of 1 : 3.  Many acetals and ketals are specified including dimethyl propional, the dimethyl acetal of stearaldehyde, cyclohexanone dimethyl acetal, phenyl acetaldehyde dimethyl acetal and acetophenone dimethyl acetal.

Abstract: 795,150. Transistor two-stable state circuits. INTERNATIONAL BUSINESS MACHINES CORPORATION. April 25, 1955 [April 28, 1954], No. 11854/55. Class 40 (6). In a circuit embodying a single transistor, input pulses are fed simultaneously to two points to cause the circuit to move from one state to the other, the circuit being arranged so that in each state a potential is generated to block the effect of the input pulse at a correponding one of the points. At least one of the blocking potentials is derived from the collector circuit. In the off state diode 33 conducts forming with resistors 30, 32 a potential divider so that diode 26 is just biased off. Since only a small collector current flows diode 20 is biased off by a comparatively large potential so that an input pulse applied over capacitor 28 is ineffective. The positive pulse fed over capacitor 27 is fed through diode 26 to raise the emitter potential of transistor 10 so that it passes to the on state. The base resistor 15 has a regenerative effect, the potentials of the emitter and base falling so that the next input pulse fed in over capacitor 27 is shunted to earth over diodes 26, 23. In contrast, the bias potential across diode 20 is reduced since the collector potential approaches that of the base. The pulse is therefore effective to return the transistor to the off state. A small capacitor 35 may be added to increase high-speed operation, and outputs may be taken from the collector or across the base resistor 15. The transistor 10 may be a multi-element junction transistor having a current gain greater than one. Specification 713,359 and U.S.A. Specification 2,644,896 are referred to.
