Abstract: 772,485. Keyboard musical instruments. WOODSIDE, A. M. July 6, 1955 [Dec. 28, 1953], No. 35969/53. Class 88 (2). Each key F of a pupil's keyboard is adapted to be unlatched or partly depressed, e.g. by means of a solenoid 13, when the corresponding key M on a teacher's keyboard is depressed. This enables the pupil to locate the required key, by touch alone if desired, and to complete the depression of the key in order to sound the corresponding note. The sounds may be produced either by the pupil's instrument or by the teacher's. In the latter case the depression of the pupil's key F causes a solenoid 37 to withdraw a stop 30 from the corresponding teacher's key M so that the teacher may complete its operation. In a modification, Fig. 3 (not shown), the solenoid 37 directly actuates the teacher's key M. For normal playing, the stops 30 may be retained in the retracted position by means of a manually rotatable rod 46 carrying a series of cams 47.

Title: Process for the production of a good conducting electrical connection between a metal compound layer and a coating of a ductile metal applied thereon
IPC: H01L21/16
Filed: 1929-11-25
Abstract: 334,140. Siemens - Schuckertwerke, Akt.-Ges. Dec. 5, 1928, [Convention date]. Direct connections between conductors. - In order to make good electrical contact with a metal compound layer such as the active layer of a copper oxide or other dry rectifier, it is known to spray on or otherwise apply a ductile metal such as zinc. In order to prevent loosening of this metal coating, according to the invention a layer of a metal compound rich in oxygen is applied thereto. This may be effected by mixing red lead or peroxide of lead with japan varnish and applying with a brush or by spraying. Iron or manganese oxide may replace the lead oxide. The adhesion of the metal coating on the metal compound layer may be further improved by applying to the metal compound layer first a thin layer of very finely divided graphite, then spraying the ductile metal, and finally coating with the mixture of varnish and oxide. The japan varnish may be replaced by other varnishes, preferably those containing no alcohol. The prepared plates may then be coated with an oily or other moisture resisting varnish as a protection against atmospheric moisture.

Title: Improvements in the manufacture and production of pulverulent fuels
IPC: C10L7/02
Filed: 1937-12-30
Abstract: 508,482. Preparing fuel; oils ; treating artificial asphalts. JOHNSON, G. W. (I. G. Farbenindustrie Akt.-Ges.). Dec. 30, 1937, No. 36125. [Class 50] [Also in Group III] Oleiferous substances containing high-boiling substances rich in hydrogen and high-boiling asphaltic substances poor in hydrogen are treated with selective solvents and the separated preferably ground asphaltic substances are treated with oxides of nitrogen or compounds yielding them to obtain pulverulent fuel of high-melting point. Suitable oleiferous substances comprise the products obtained from coals rich in bitumen or oil shales by pressure hydrogenation or extraction, or tars or asphaltbasic petroleums. In the example, mid- Germany brown coal is triturated with tetrahydronaphthalene and extracted at 415‹ C. and 150 atmospheres in the presence of .1 cubic metre of hydrogen per kilogram of coal. The solid constituents are filtered off and the filtrate treated at 125‹ C. with 4 times its volume of butane to separate the asphaltic products which are treated with nitrous gases at ordinary temperature to yield a fuel suitable for Diesel dust motors. Paraffin wax and lubricating oil are obtained by pressure hydrogenation of the substances recovered from the butane solution after dilution with brown coal tar middle oil.

Title: Methods for the manufacture of inflammable metals of a semi-pyrophoric nature
IPC: C06C15/00
Filed: 1933-11-06
Abstract: Metals in semi-pyrophoric form (i.e. metals in such a state that their ignition temperature lies between 50 DEG  C. and 300 DEG  C.) are manufactured by the reduction of metal compounds by thermal decomposition in the presence of an inert gas or gases, or by chemical reduction of metal compounds by hydrogen at raised temperature, the temperature and reaction conditions being maintained throughout the reaction intermediate those required to produce non-pyrophoric metals and those to produce pyrophoric metals.  For chemical reduction, oxides, nitrates, carbonates, sulphates, oxalates, tartrates or citrates may be employed; for thermal decomposition, oxalates, tartrates or citrates. Alternatively, metal compounds may be reduced in such manner as to produce pyrophoric metals, the latter being then cooled in a current of hydrogen and when cold treated in inert gases, air being excluded.  For example, semi-pyrophoric iron may be produced by heating the oxide for an hour at 390 DEG  C. in a hydrogen current and then cooling it in hydrogen or semi-pyrophoric nickel may be produced by heating the nitrate in hydrogen for 50-60 minutes at 340-360 DEG  C.  Specifications 14971/08, [Class 1], 233,029, [Class 82 (i)], 372,958 and 433,117 are referred to.

IPC: D06M23/00
Filed: 1966-08-15
Abstract: 1,114,539. Treating and finishing acrylic fibre fabrics; textile treating apparatus. E. I. DU PONT DE NEMOURS & CO. 15 Aug., 1966 No. 36372/66. Heading D1L. D1P and D1S. A smooth fabric is prepared from a fuzzy fabric formed from synthetic staple fibres of an acrylonitrilepolymer by applying substantially only to the fuzz of the fabric a swelling agent, steaming it and pressing the steam heated fuzz to the fabric. The free portion of the fibres at the surface may be mechanically oriented against the fabric surface in the direction of the weave or stitch of the fabric. The fabric may also be treated with steam and the fibres on the surface of the fabric oriented prior to the application of the swelling agent. The swelling agent as such or in the form of a solution in for example water or acetone may be applied to the fabric in the form of a mist. The swelling agent may be ethylene carbonate, 1,2- propylene carbonate, dimethyl sulphoxide, tetramethylene sulphone, dimethyl formamide dimethyl acetamide, gamma - butyrolactone, sodium, lithium, calcium, potassium or magnesium thiocyanate, lithium, sodium, cadmium or colbaltous, iodide, calcium, lithium- or ferrous bromide or zinc, cupric, magnesium, ferric or barium chloride. Woven, knitted or non- woven fabrics made from staple fibres of polyacrylonitrile, copolymers of acrylonitrile with vinyl acetate, vinyl chloride, methyl acrylate or vinyl pyridine, or acrlonitrile / methlacrylate / sodium styrene sulphonate terpolymers, comprising at least 70% by weight of acrylonitrile may be treated. In Fig. 1 fabric 11 is passed from supply roll 10 over roll 12 and spreader 13 by pull rolls 14 to chamber 15 where it passes over alignment cells 16 which emit steam and pres the surface fuzz into the fabric surface orienting these fibres in the lengthwise direction of the fabric. The fabric is then passed over spreader 18 between rolls 19 and 20 before entering chamber 17 where a mist of swelling agent is applied and is passed to chamber 21 where steam from steam cells 22 is applied, the cells 22 being provided with lips 24 which press the fuzz on to the fabric surface, and then to wind up roll 30. The alignment cells 16 and steam cells 22 may be covered with a fabric woven from a high-melting polyamide fibre through which the steam passes, the fabric being treated rubbing against the covering fabric giving better orientation of the surface fibres. The nozzle used to provide the mist that is applied to the fabric may comprise a liquid basin or trough provided with an overflow trough in which a roll is rotatably mounted to pick up liquid from the basin or trough and carry it to a capillary tube from which it is atomized by a stream of air caused to pass by its outer end. Alternatively an apparatus which produces a mist by centrifugal force, the solution being thrown from a disk rotating at high speed and the resulting mist being blown on to the surface of the fabric by a flow of air, may be used.
