Filed: 1930-10-17
Abstract: 362,094. Electromagnets. HALL, N., Westgarth, Lyndhurst Grove, Low Fell, Co. Durham. Oct. 17, 1930, No. 31160. Drawings to Specification. [Class 35.] A " hair-pin " or " horse-shoe'" electromagnet is provided with a sheath covering both coils and preferably closed at one end of a material which may be made to expand or contract at will so that by placing the sheath.over the magnet in the expanded condition and subsequently causing it to contract, it will conform closely to the shape of the magnet and hold the parts tightly together. The sheath may be of cellulose hydrate or a gelatinous material applied wet so that on drying it shrinks on to the magnet and coils. The leads are secured at the inner end of the magnet and brought out at the open end of the sheath. The sheath may be filled with a high melting point wax or other insulating compound or the external and internal surfaces may be treated with varnish to prevent reabsorption of moisture.

Title: Improvements in or relating to ultra high frequency oscillators
IPC: H03B9/01
Filed: 1939-11-30
Abstract: 537,918. Electron oscillators. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Nov. 30, 1939, No. 31193. Convention date, Nov. 30, 1938. [Class 39 (i)] In an ultra high frequency oscillator a cloud of electrons move within a resonant cavity 3, Fig. 1, to produce standing electromagnetic waves therein, a loop 25 within the cavity radiating energy. An accelerator anode 9 is mounted within a cathode which is in the form of a frame and a solenoid 15 surrounds the metal envelope ; electrons move towards the anode 9 but are diverted by the magnetic field to pass towards the cathode frame on the side opposite from which they issue. On approach to this side they are retarded and turned back starting oscillations within the cavity. The waves produced increase the amplitude of movement of electrons in phase with the wave causing movement outside of the cathode frame and flow to the metal envelope ; the out-of-phase electrons are slowed up giving up energy to the standing waves, until they fall on the anode 9. The end wall of the cavity is adjustable for tuning. In a modification the cathode 45, Fig. 2, is a circular disc and the accelerator anode 49 a circular grid ; the envelope 43 is biased negatively and the electrons produce circular standing waves. In a modification of this form the cathode 65, Fig. 4, is surrounded by a cylindrical accelerator 71 and a magnetic field causes side movement of the electrons ; in phase electrons are collected by the envelope. In a further construction electrons from the cathode 87, Fig. 5, are directed by electrodes 89 towards a retarding electrode 91 across the opening of a cavity 83 forming part of a sphere. A permanent magnet may be used in place of an electromagnet. The Specification as open to inspection under Sect. 91 also describes an arrangement of centrally arranged cathode and envelope, wherein standing waves are generated without intervening grid. This subjectmatter does not appear in the Specification as accepted.

Title: An improved washing machine for pickled material in the form of strip or wire
IPC: C23G3/02
Filed: 1933-11-10
Abstract: 433,289. Cleaning metals. BUSSE, C., Sundwig, Iserlohn, Germany. Nov. 10, 1933, No. 31428. Void [Abridged as open to inspection under Sect. 91 of the Acts, May 11, 1934]. [Class 82 (ii)] [See also Group XIII] Wire or strip, after being pickled, is passed into a washing chamber in which it travels vertically upwards between cleaning devices such as brush or felt rollers. Water is supplied to both sides of the strip &c. by means of nozzles adjacent the top of the chamber and trickles down the material, forming a bath at the bottom of the chamber into which the material from the pickling tank is introduced. Neutralizing agents such as soda may be added to the washing water. Fig. 1 shows a plant for annealing, pickling, washing, and drying wire or strip. The strip 2 passes through an electrically or gas heated annealing furnace 1 into a water trough 3 separated by a partition 5 from a pickling tank 4. From the pickling tank the strip passes into a washing chamber 6 comprising a casing 9 surrounded by heat insulating material 12, such as cork plates. The strip passes through the accumulated water 6<1> at the bottom of the chamber and travels vertically upward between cleaning rolls 7 and is sprayed with water by means of nozzles 8 near the top of the chamber. Guide plates 10 are arranged beneath the cleaning rolls to direct the water removed by the rolls back to the strip. Soda solution is preferably supplied by nozzles 15 situated below the upper cleaning rolls. The strip passes from the chamber 6 to a drying chamber 13 mounted on the annealing furnace, and thence to coiling means 14. The water supplied to the nozzles 8 is preferably taken from the water trough 3 and the water accumulating at the bottom of the chamber 6 may be passed back to the trough 3 or may be passed through a heat-exchanger 11 which heats fresh water for the trough 3. Fig. 2 shows a pickling, washing, and drying plant, the washing chamber 6 being of similar construction to that shown in Fig. 1 but having mounted thereon squeezing rolls 20, e.g. of rubber, to remove liquid from the washed strip, and two heated drying drums 21.

Title: Compressors for gas turbine engines
IPC: F04D29/52
Filed: 1970-06-30
Abstract: 1280113 Centrifugal and axial-flow compressors; gas turbine engines AVCO CORP 30 June 1970 [4 Aug 1969] 31621/70 Headings F1C and F1G A compressor in or for a gas turbine engine comprises an axial-flow section 32, 46, Fig. 1, and a downstream, contra-rotating mixed-flow section 62. The axial-flow section discharges air at subsonic absolute velocity. The mixed-flow section has an inlet portion which is of substantially constant flow area and receives the air at supersonic relative velocity to thereby produce shock waves and reduce supersonic flow to subsonic, whereafter the air is radially accelerated and diffused in the outlet portion of the mixed-flow section. The impeller blades of the latter may be divided into an inlet row and and outlet row separated by a row of stator blades, Fig. 3 (not shown). Stator vanes (150), Fig. 8 (not shown), may be located immediately upstream of the mixed-flow section to equalize the relative velocity of the entering air over the radial extent of the annular flow duct. In the gas turbine engine shown, the compressed air is discharged through a diffuser 84 into combustion apparatus 18 comprising an annular series of cylindrical combustion units 90 which deliver hot gases into a duct 92. The latter discharges the gases through a full-admission inlet nozzle to drive turbine wheels 98, 114, which drive the respective compressor sections, and to either drive a further turbine wheel having an output shaft 30 or exhaust through a nozzle to produce propulsive thrust. Alternatively, the two compressor sections may be driven by a single turbine wheel via gearing. Sump housings 54, 72, 120 for the shaft bearings are each sealed at both ends by friction or labyrinth seal assemblies 60, 74, 106, 122.
