Title: Mixing devices for gases
IPC: A61H31/00
Filed: 1974-02-07
Abstract: 1429435 Valves JUNGNER INSTRUMENT AB 7 Feb 1974 [7 Feb 1973] 05745/74 Heading F2V In a device for mixing anaesthetic gases, at constant pressure, in differing proportions and with a variable total flow, gases A and B are controlled by valves 1A, 1B respectively which have a flow rate proportional to the displacement of their operating rods 10A, 10B. The valves are stationary relative to a support structure 12 in which a carriage 14 may be reciprocated by a screw 15. To the carriage are attached two actuating bars 18, 19 in contact with the operating rods, which are held in contact with them by springs within the valves. Sliding the carriage varies the amount of each gas in the mixture but the total flow is unchanged. The bars are pivoted to the carriage and can be rotated by a handle 21 to vary the total flow rate. Each valve comprises a rod 7, having one or more axial grooves 8, sliding in a partition wall 6 to control the degree of opening of the grooves. A spring 9 biases the valve to the closed condition and maintains the operating rod 10 in contact with the actuating bar. In a further embodiment, Fig. 3 (not shown), a third valve (1C) is provided to control a third gas (C) so that a constant flow of gases (A) + (B) or (B) + (C) can be provided. In this embodiment the common pivot for the two operating bars is carried on a further screw controlled carriage moving in and transversely to the main carriage. The outer ends of the two arms are attached to the main carriage by pin-in-slot arrangements so that as their pivot is moved transversely they each maintain an equal angle to the line of motion of the main carriage. The operating rods of the three valves are equally spaced at a distance such that only rods (10B) and (10A) or (10C) are in contact with the two operating bars at any one time, the other valve 1C or 1A remaining closed by its spring. An additional gas (D) may be controlled by a further valve actuated by a bar coupled to the control bars for the valves of gases (A) and (B) so as to have always the same angle of inclination as the bars of the gases (A) and (B) but translationally moveable relative to the valve for the gas (D) separately and independently of the bars for the gases (A) and (B)

Title: Improvements in electrically-heated laundry irons
IPC: D06F75/26
Filed: 1922-02-27
Abstract: 189,704. Booth, H. Feb. 27, 1922. Electric hand-irons having means for regulating the degree of heat comprise a base-plate 1 formed with a recess 2 in which the heating unit 3 is disposed, and an upper plate 8 carrying a fixed insulated electric contact spigot 17 and a revoluble contact spigot 12, the latter having a. contact arm 13 fixed to it which bears upon the heating coils and varies the resistance in circuit as this contact spigot is rotated. Studs 6, 7 passing through the upper plate and screwing into the base plate clamp the heating element between these plates and also support the handle 10; the arm 13 moves in a recess 11 in the plate 8 and bears on the coils through an arcuate slot in the upper layer of insulation. An indicator arm 14 fixed to the spigot 12 moves over a scale on the upper surface of the plate 8 and serves to move the contact arm. The winding is longitudinal on the arm and the spigot 17 bears upon one end while the other end is fixed to the insulated plate, anticlockwise movement of the arm 13 thus cuts out coils and increases the degree of heat.

Abstract: 326,969. Booth, V. Feb. 25, 1929. Rotary mixers.-A mixing-machine comprises an open-ended drum rotating about a horizontal shaft and a conveyer working in a trough disposed axially therein and fitted with adjustable openings whereby the material fed to the drum by the trough may be continuously circulated within the drum; when the mixing operation is complete the closure of an opening in the trough within the drum effects the discharge of the material to other openings outside of the drum. The drum is fitted with lifting blades and inclined vanes and the trough is covered for a part of its length, the other part being fitted with outwardly-inclined deflectors by which the material falling from the lifting blades is collected in the trough. The drum 6, fitted with lifting blades 12 and variably-inclined vanes 11, is supported on driving-rollers 17 on longitudinal shafts 18 interconnected by a belt and driving the conveyer 2 by a belt 23 and bevel gear. The conveyer, fitted with slats 3, works in a trough 4 extending through the drum ends 16 and fitted with an aperture 7 within the drum, and apertures 8. 9 outside. These apertures are controlled by a slide 10 arranged so that when the apertures 8, 9 are open the aperture 7 is closed, and vice versa. The trough is fed from a hopper 1 and within the drum near the hopper is fitted with outwardly-inclined deflector blades 14; nearer the other end it is covered bv a roof 13 of inverted V-section. During normal working with the opening 7 uncovered, the material falling therethrough is gradually worked to the other end of the drum and lifted so as to fall on to the conveyer and be moved again along the trough to the opening 7. When the latter is closed, the material is discharged through openings 8, 9.

Title: Improvements in the manufacture and production of alkali metal nitrate from calcium nitrate and alkali metal chloride
IPC: C01D9/12
Filed: 1934-02-26
Abstract: In the production of alkali metal nitrates from calcium nitrate and alkali metal chlorides by the aid of zeolites, fresh or regenerated zeolite is washed with several washing liquids of increasing nitrate content obtained by washing out adsorbed salts from the exhausted zeolite, and exhausted zeolite is washed with several solutions of decreasing nitrate content resulting from the pretreatment of the fresh or regenerated zeolite.  By these means, the need for evaporation of the washing liquids, which circulate continuously in the process, to recover their nitrate content is obviated, and the initial saturation of the zeolite with nitrate enables relatively concentrated solutions of nitrate to be obtained.  In an example illustrating the production of sodium nitrate, twelve towers containing zeolite are employed, six being in use at any one time, and the remainder being out of commission for the washing and regenerating operations.  From a 40 per cent solution of calcium nitrate a 36 per cent solution of sodium nitrate is obtained. Specifications 407,311 and 407,313 are referred to.

Abstract: 637,900. Making dynamo-electric machines. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. March 4, 1948, No. 6760. Convention date, March 13, 1947. Drawings to Specification. [Class 83 (ii)] A method of making rotors for induction motors includes the steps of assembling a stack of laminations having winding-receiving slots, casting squirrel-edge windings integrally with the laminations and then heating the entire rotor, the laminations and the windings being of different metals having different rates of thermal expansion. The heat treatment is stated to have the effect of withdrawing the windings and the laminations from the close interlocking contact which results from the casting operation and so reducing the conductivity between the core and the windings. When the windings are of aluminium the heating also forms, or increases the amount of, an oxide film on the windings. The heated rotor is then applied over the rotor shaft and secured thereto by a shrink fit. The assembly is finally trued to accurate dimensions by a turning operation.
