Patent GB-706574-A (GB)
Title: Process for manufacture of aromatic thiosemicarbazones
Filed: 1951-08-27
Abstract: Thiosemicarbazones of aromatic aldehydes are prepared by reacting an aromatic aldehyde in an aqueous acidic reaction medium with hydrazinium thiocyanate at a temperature between room temperature and the boiling point of the mixture.  The reaction medium may be an aqueous solution of acetic acid which may also contain a lower aliphatic alcohol.  Instead of hydrazinium thiocyanate there may be used a mixture of a hydrazine salt and a source of thiocyanate anions, e.g. a mixture of hydrazine sulphate and an alkali metal thiocyanate.  The alkali metal salt may be separated by cooling the hot solution of the mixture.  The aromatic aldehyde may be substituted, e.g. by hydroxy, amino, acylamino, nitro, alkyl, aralkyl, alkoxy, aralkoxy, aryl, acyloxy, halo, sulphono, sulphonamido and N-acylsulphonamido groups.  In Examples, (1) a mixture of p-hydroxybenzaldehyde, acetic acid and ethanol is heated with an aqueous solution of hydrazine thiocyanate and then cooled to separate the p-hydroxybenzalthiosemicarbazide; (2) and (3) p-acetylaminobenzaldehyde is heated with acetic acid and an aqueous solution of hydrazine thiocyanate and cooled to yield p-acetylamino benzalthiosemicarbazide; (4) p-dimethylaminobenzaldehyde acetic acid and an aqueous solution of hydrazine thiocyante are heated together to give p-dimethylaminobenzalthiosemicarbazide; and (5) p-nitrobenzalthiosemicarbazide is similarly prepared from p-nitrobenzaldehyde.

[Class 49] [Also in Group XVII] A food-stuff package comprises a number of edible articles of pre-determined individual size and shape, a flexible, non-porous and readily-deformable envelope containing an edible component e.g., sauce, the envelope being sealed against leakage and disposed in contact and in flexed conformity with the surface contour of the adjacent articles, arid a rigid external container enclosing the articles and the sauce. In the construction shown the flexible container 12 is in the form of a tubular envelope of rubber hydrochloride film having crimped seals 14 at each end which encloses a quantity of sauce 12<SP>1</SP>. Sausages 11 are pressed by contact of the can 10 into engagement with the sides of the container 12 which is thus deformed into a cross section of fluted profile (Fig. 3, not shown). The rigid container is in the form of a can 10 which also contains brine.

Abstract: 1369959 Donning and doffing NIPPON KEORI CO Ltd 1 May 1973 20700/73 Addition to 1306899 Heading DID [Also in Division F2] A spindle rail 15 is movable laterally from the spinning position (LHS of Fig. 1) to a second position (RHS of Fig. 1) to facilitate donning and doffing on a spinning machine. Movement of rail 15 is effected by a crank 41 connected to the spindle rail 15 by a resiliently deformable arcuate link 42. The crank 41 is rotated by shaft 40 through an angle slightly greater than 180‹ to cause movement of the spindle rail 15 and to allow the deformable link 42 and the crank 41 to act as an overcentre self-locking toggle mechanism to firmly hold the spindle rail 15 in either of the two positions. The spindle rail may be supported by parallel links 32, a shaft 44 in sliding bearings (Fig. 2 not shown), and by a pressure cylinder when the rail 15 is in the donning/doffing position remote from the spinning machine. Spindle rails on either side of the machine may be moved simultaneously by a common crank 41. The spindles on the rail may be rotatable by a pivoting belt drive which is operable at all positions of the spindle rail, (Fig. 4 not shown). A ring rail 21 may be laterally displacable together with the spindle rail, the ring rail lifting device 22 being disengaged from the ring rail 21 prior to the lateral movement.

In Figs. 11-16 (not shown) arcuate guides surround part of the pulley and/or jockey pulleys guide the belt on to the pulley and maintain engagement between the belt and pulley. The belts may be made of plastic or steel and may include a layer of magnetic material in which case magnetic guide means may replace the above guides. The belt gear may be used in servo-systems or recording tape drives.

Abstract: 489,069. Toy electric railways. DUNHILL, A. July 28, 1937, Nos. 20895 /37 and 2716/38. [Class 132 (iii)] Toy electric vehicles with couplings comprising a hook member and a complementary bow-shaped member as described in Specifications 489,067, 489,068, and 489,074 are uncoupled by an electromagnet and at the same time the current to the rail is cut off. A strip t is normally held by a spring w to join the leads k<1>, k<2> in a circuit for driving the train from a live rail. When the button r is pushed to energize the magnet e for uncoupling the vehicles, the pin z of insulating material depresses the strip t thus breaking the rail circuit. In the modification shown diagrammatically in Fig. 4, operation of the switch 2 and one of switches 5, 6, 7, 8 corresponding each to an electromagnet, uncouples the train without stopping the vehicle. The circuit is adapted for two trains one driven from each of the outer rails. Each of the two-way switches 3, 4 controls, in the position shown, its respective train through a resistance 11 or 14. When switch 3 or 4 is put into the dotted line position and one of the switches 5, 6, 7, 8 is operated the corresponding rail circuit is broken and the train uncoupled by the corresponding magnet.

Foodstuffs, medical appliances, medicines, sera, &c., are cold sterilized, i.e. sterilized at temperatures where heat alone is not effective, by treatment with bactericidal gases, e.g. alkylene oxides or alkylene imines, in a pressure chamber, the sterilization being effected at a pressure between 3 and 6 atmospheres (gauge) with a mixture of bactericidal gas and a gas having no bactericidal or sterilizing effect at atmospheric pressure, e.g. carbon dioxide. Mixtures of ethylene oxide and carbon dioxide in a weight ratio of from 1: 9 to 1: 25 are specified, sterilization being effected preferably between 20‹ C. and 60‹ C. The materials to be sterilized may be unwrapped or wrapped in plastic foil; the sterilization at superatmospheric pressures of loam wrapped in a polyethylene foil of thickness about 50Á is described as illustrating the sterilizing effects of a mixture of ethylene oxide and carbon dioxide by diffusion through the foil. In Fig. 2 the bactericidal mixture is held under pressure in a cylinder 1 from which it is passed through a pressure-reducing valve 5 to a preheater 6. The gas is led through a check valve 8 to a pressure chamber 10 containing the materials to be sterilized.
