Title: Dimensionally stable mineral-wool fibreboard
IPC: D21H11/04
Filed: 1964-04-09
Abstract: A strong, dimensionally stable fibreboard comprises mineral-wool fibres bonded together with a binder comprising kraft fibres coated with a synthetic rubber.  The synthetic rubber used may be a butadiene-styrene copolymer, a butadiene-acrylonitrite copolymer, neoprene, an isoprene rubber, a homopolymer of butadiene, or a homo- or co-polymer of a homologue of butadiene. The kraft fibres may be pretreated with cationic melamine-formaldehyde resins before the addition of latex, or they may be treated with alum and then neutralized with ammonia, or the latex may be added to untreated fibres, and precipitated by then adding alum.  The board is made from a mixed slurry, which may be made in any of three ways: (1) the kraft fibres are slurried in water, the synthetic rubber is deposited on them, and the mineral fibres then mixed in; (2) the kraft fibres and mineral fibres are formed into a slurry and the kraft fibres of this mixed slurry then coated with synthetic rubber; (3) the kraft and mineral fibres are slurried separately, the synthetic rubber added as a latex to and precipitated onto the fibres of the kraft slurry, and the two slurries then mixed.  Clay, to serve as a filler may be added to the slurry or one of the slurries, and may be coated with synthetic rubber.  Starch may be added as an additional binder to the slurry or one of the slurries.  The board obtained may be used as an acoustic tile or fireproof panel.

Title: Improvements in telephone sub-stations
IPC: H04M1/58
Filed: 1940-10-03
Abstract: 542,739. Substation circuits. STANDARD TELEPHONES & CABLES, Ltd. (Nippon Electric Co., Ltd.). Oct. 3, 1940, No. 14840. [Class 40 (iv)] To eliminate side-tone, the receiver transformer of a local battery substation set is shunted on the line side by metal rectifiers R1 ... R4. The circuit is particularly useful for a partyline train dispatchers' system, but on such a case, it is preferable to have the microphone circuit normally open to ensure that the receiver is not ,put out of action by the noise of passing trains and also to insert impedances (preferably resistances) in the shunt circuits, these resistances being graduated according to the position of the set and being larger the nearer the set is to the end of the line. In the absence of this provision, the rectifiers of several neighbouring sets, which may assume their low impedance condition in response to speech in a single microphone, would have an undesirable shunting effect on the other sets. Specification 542,643 is referred to.

Title: A process for treating extracted oil-seed waste with fat and/or oil
IPC: A23K20/158
Filed: 1963-04-17
Abstract: In producing an animal feed, oil and/or fat is mixed, in the absence of water, steam or condensed steam, with flakes of oil-seed waste, from which natural oil has been extracted by a solvent, such as benzine, in a suitable extractor and still containing some solvent, which facilitates impregnation of the flakes by the added oil and/or fat.  The oil and/or fat may be thinned with solvent before being added to, e.g. sprayed on to, the flakes in the extractor.  The treated flakes are then passed through a device, e.g. a toasting device, which expels the solvent, and then through a cooling drum, from which the animal feed is discharged in a finely divided form. Waste from the following products may be used: cocoa beans, palm kernels, copra, rape seed, sunflower seed, sesame seed, cotton seed, linseed, soya beans, groundnuts and maize.  Oils and fats e.g. hydrogenated, from whales, cattle, pigs, slaughter houses, fish and soyabeans may be used.

Title: Confocal cavity optical gas sensor
IPC: G01N21/03
Filed: 1974-04-04
Abstract: 1460612 Photo-electric gas-analyzers  PERKIN-ELMER CORP 4 April 1974 [6 April 1973] 15019/74 Heading G1A A gas analyzer is provided with a long effective path length by utilizing a confocal cavity comprising a pair of opposed reflectors mounted in spaced apart coaxial relation in a housing, the reflectors being partially transmissive and having spherical surfaces, collimated radiation being passed into the cavity through one reflector and the radiation transmitted by the other reflector being applied to a detector. The concentration of a particular gas is determined by measuring the transmission at a wavelength absorbed by the gas and at a reference wavelength which is not absorbed. As shown, Fig. 1, the concentration of carbon monoxide (CO) in air is measured using a confocal cavity defined by two spherical mirrors 22, 22' spaced by their radius of curvature and being partially (1%) transmissive. Radiation from an IR source 50, which may be an electrically heated filament in an inert gas environment, is collimated by a mirror 56 and passed through reflector 22 into the cavity where it undergoes repeated reflections between the mirrors a small proportion passing out at each reflection. The radiation transmitted by reflector 22' is focused on to a detector 32 by a mirror 72. An electric motor 88 drives a filter wheel 100 which also carries fan blades 86 to draw-in sample air through a filter 92 and pass it through conduit 96 into the measurement cavity. The filter wheel is provided with interference filters of three different passbands, one to select the reference wavelength and the other two wavelengths suitable for absorption measurements of high and low concentrations of CO. The output of the detector is applied to two sample and hold circuits, synchronized by pulses picked up from slots in the filter wheel by appropriate detectors, to produce absorption band and reference band signals which are applied to a comparitor feeding a meter calibrated in terms of CO concentration.

Title: Method for the separation of optically active ª‡-methylphenethylamines

Abstract: 550,916. Alpha methyl phenethylamine. NABENHAUER, F. P. Oct. 16, 1940, No. 15333. Convention date, Nov. 3, 1939. [Class 2 (iii)] l- α - Methylphenethylamine is isolated from material containing both d- and l - α - methylphenethylamine by reacting the material with d tartaric acid in proportion to produce a solution of neutral d - and l - α - methylphenethylamine - d tartrates, and crystallising from this solution the l - α - methylphenethylamine - d - tartrate from which l - α - methylphenethylamine is liberated. The starting material may comprise dl - - α - methylphenethylamine or it may comprise a material containing an excess of the d - isomer. In the latter case it is preferred to effect a preliminary separation of the excess of the d - isomer by crystallizing the acid tartrates, in which case the d - isomer separates first. The l - isomer is then isolated by neutralising the solution to form the neutral tartrates and crystallising according to the present invention. The free base is isolated from the tartrate salt by the addition of an aqueous solution of caustic soda. Specification 508,757 is referred to.
