Title: Improvements relating to sealed containers
Inventor: EASTON HAROLD
IPC: B65D43/02
Filed: 1953-09-08
Abstract: 758,363. Indicating-apparatus. FERRANTI, Ltd. Sept 2, 1954 [Sept. 8, 1953], No. 24778/53. Class 106 (4). [Also in Group XVII] A sealed container for indicating-apparatus comprises an outer case 10 with at least one slot parallel and near the rim of its open end defining a strip 15<SP>1</SP>, an interiorly supported gland 23 disposed within the open end and a closure member 24 held in engagement with the gland 23 by radially-inward distortion of the strip 15<SP>1</SP>. Indicating apparatus is located within an inner cylinder. 19 which is a sliding fit in the outer cylinder 10 and has flanges 20, 21 engaging glands 22, 23. A glass 18 is inserted between the gland 22 and a gland 17 located by a flange formed at the end of the outer cylinder 10 and the gland 23 is held by a baseplate 24 which is pressed inwards to make the glands effectively seal the container and is then locked by distorting inwards three identical equi-spaced strips 15<SP>1</SP>. A disc may be placed on the base 24 within the flange 21 to limit the inward expansion of the gland 23 and ensure sufficient outward expansion to seal the space between the base-plate 24 and outer cylinder 10. To accommodate a different thickness of glass 18 or length of cylinder 19 a spacing washer may be inserted between the baseplate 24 and the strips 15<SP>1</SP>. This washer may be formed with portions of different thickness arranged in three series so that identical portions engage the three strips at any one time. These portions may be arranged in a series of shallow steps 34, Fig. 6, the washer being rotated until the appropriate thickness is obtained.

Title: Improvements in and relating to electric switching devices especially for current rectifiers
IPC: H02M1/20
Filed: 1939-08-29
Abstract: 532,410. Electromagnetic interrupters. BRITISH THOMSON-HOUSTON CO., Ltd. Aug. 29, 1939, No. 24793. Convention date, Aug. 29, 1938. [Class 38 (v)] [Also in Group XXXV] With switch 7 closed, operation is initiated by momentary closure of switch 8 to energize a coil 5 which attracts a mass of powdery magnetic material 6 to bridge contacts 2', 3'. This makes a circuit for coil 4 which attracts the material 6 to bridge contacts 2, 3, so breaking the circuit of 4 and re-making that of 5. The powder may be Swedish pig or the material known under the Registered Trade Mark " Mumetal" " and is stated to give approximately a sinusoidal waveform. The arrangement shown is an inverter, but the invention may be used for rectifying. Fig. 1 shows a construction of the device, the outer contacts 3 and contact 2 being annular in form and concentrically arranged in an exhausted or gas or liquid-filled container 1 with the coils 4, 5 surrounding it.
Patent GB-467032-A (GB)
Title: Process for rendering commercially useful the gasol and ethylene contained in industrial gases
IPC: A43D25/18
Filed: 1935-09-05
Abstract: Coke-oven and like industrial gases are treated with adsorbents to remove a mixture comprising ethylene and other volatile constituents and also less volatile hydrocarbons such as propylene, propane, butylene, butane, &c.  This mixture obtained by flushing the adsorbent is partly liquefied by pressure, or is wholly liquefied and then partly evaporated.  The more volatile fraction consisting chiefly of ethylene may be again treated with an adsorbent to remove residual quantities of the less volatile hydrocarbons.  An adsorbent which has already been charged in the original treatment of the coke-oven gas may be used for this purpose.  The purified fraction rich in ethylene is suitable for conducting organic reactions, such as condensation with benzene to produce ethyl benzene.  The less volatile hydrocarbons may be liquefied for use as fuel. p  The Specification as open to inspection under Sect. 91 comprises also the separate removal of the ethylene and the less volatile hydrocarbons from industrial gases, the latter being removed by active carbon and the ethylene subsequently removed by solution in sulphuric acid. This subject-matter does not appear in the Specification as accepted.

Cellulose esters and ethers, processes for making filaments from.-To solutions of cellulose acetate to be used in the manufacture of artificial silk, there are added, in order to facilitate the spinning process and the production of fine threads, dispersively-acting substances in such quantity as to produce solutions containing particles of uniform and smallest size, that is to say, stable solutions of minimum viscosity. Suitable additions are non-solvents such as alcohols, water, toluene and homologues thereof, esters, ethers, mixtures containing alcohol or water such as aqueous formaldehyde solution, and mixtures of hydrocarbons or halogen derivatives thereof; and generally, substances containing hydroxyl and carbonyl groups, or substances belonging to the class of carbohydrates. It is observed that an addition of a too-large quantity of the dispersing agent produces a re-aggregation of the dispersed particles. The solution containing the dispersively-acting subsances is preferably preheated to above 30‹ C., preferably between 40‹ C. and 50‹ C. Specification 310,046 is referred to. The Specification, as open to inspection under Sect. 91 (3) (a) includes processes generally for reducing the size, of the particles in solutions of cellulose esters and ethers, and it states that heatins alone has the desired effect.

Abstract: 352,788. Pocketknives &c. GAUNT, C. F., Warstone Parade Works, Birmingham. Aug. 26, 1930, No. 25403. [Classes 30 and 128.] A fruit or other pocketknife, which may be of stainless steel, has only one scale 1, the edge of which is flanged at 10 to protect the blade edge when the knife is closed and to form a stop to limit the extent to which such blade 4 can be opened. The knife is thus readily cleaned and will not collect dirt. The blade and scale may be curved in cross section. The blade is maintained in position by a rivet 7 and washers 8 on both sides of the scale, one of which washers may have lugs 18, 19, Fig. 7, to engage a recess 20 in the flange 10 to lock the blade in open and closed positions. Alternatively, a lug may be formed on the blade, or recesses in the blade may be engaged by a lug on the scale. An additional blade 12 may carry an edge 14 and a stop 15 to act as an incisor for oranges or other fruit, or, if provided with a fulcrum point, will serve as a tin-opener. Alternatively, the incisor may be formed on the end of the scale, Fig. 7, when the stop 15 serves as an additional bladeguard. Fruit incised by the tool 12 may be peeled by a shallow gouge 16, which may, however, be made sufficiently deep to serve as a spoon. A hole may be formed on the scale 1, so that the blade 4 can serve as a cigar-cutter. A corkscrew, a nail file surface 21, and a millimeter or inch scale may be added, and advertising or other matter may be engraved or stamped upon the knife.
