The port 1 may be connected by switching circuitry either directly or through a quarter-wavelength line L, to a first terminal. The port 4 is connected directly to a second terminal, and either the port 2 or the port 3 may be connected to a third terminal. As described, switching operations are performed by two relays R 1 , R 2 . Two aerials A 1 , A 2 , which are each inclined at 45 degrees to the horizontal, and are inclined at 90 degrees to each other, are respectively connected to the first and second terminals. A transmitter or a receiver S is connected to the third terminal. When the relay R 1  is in position (a), the quarter-wavelength line L is in circuit and, with the R 2  in position (c), so that the transmitter or receiver S is connected to the port 2, the aerials are phased for waves with vertical linear polarization. If the relay R 2  is changed to position (d), so that the transmitter or receiver S is connected to the port 3, the aerials are phased for waves with horizontal linear polarization. When the relay R 1  is in position (b), so that the line L is not in circuit, the aerials are phased for waves with circular polarization. Whether that polarization is right- or left-handed depends upon the position of the relay R 2 . In other embodiments, the relay R 2  is omitted, and the third terminal is directly connected either to the port 2 (Fig. 2, not shown) or to the port 3.

Abstract: 765,669. Jet propulsion plant. ARMSTRONG SIDDELEY MOTORS, Ltd. July 20, 1953 [Sept. 16, 1952], No. 23205/52. Class 110 (3). [Also in Group XII] In a gas generator, for example in a rocket motor, a disruptible member in the combustion zone is burnt through at a temperature beyond a predetermined limit, thereby breaking the circuit controlling the supply of fuel and oxidizer to the generator. As shown, the wire 24 extends through the generator zone 11 of a rocket motor and the burning through of the wire effects interruption of both the fuel and oxidizer supplies and of the igniter circuit 40. The main fuel valve 21 and the oxidizer valve 15 are normally maintained open by the highpressure fluid controlled by valve 26 but upon the breaking of 24, valve 26 connects the highpressure system to the vent 48. The wire 24 may be replaced by a tube connected, for example, to a supply of high-presusre nitrogen and the fall in pressure upon fracture of the tube effects operation of the relays as in the first system. Specification 763,962 is referred to.

Title: Improvements relating to guard or fence mechanisms for hydraulic presses
IPC: F16P3/04
Filed: 1938-08-10
Abstract: 517,659. Guards for hydraulic presses. UDAL, J. D. Aug. 10, 1938, No. 23563. [Class 69 (ii)] [Also in Group XXIV] A guard mechanism for a hydraulically operated press with a vertically movable ram, comprises the combination of a guard that can be raised or lowered, a catch lever or. levers associated with the guard, and an abutment or abutments mounted on the ram, the catch lever or levers being adapted to co-operate with the abutment or abutments to prevent accidental movement of the ram, and to be moved to an unobstructive position by movement of the guard to its operative position, the abutment or abutments being adapted by co-operation with the catch lever or levers to prevent movement of the guard excepting when the ram is in its inactive position. The bed a supports the lower tool carrying platen b and vertical posts c which support the hydraulic cylinder d with press ram e and upper tool-carrying platen f sliding on the posts c. Liquid can flow from a replenishing chamber g past a valve h to the cylinder d. The guard m slides on a pair of rods j and has a balance weight n. A lever r is pivoted to the press frame at t and is connected by a link s to the guard. A bell-crank catch lever u is pivoted at v to the press frame and is connected by a link w to the lever r. The other arm x of the lever is shaped as a hook adapted to pass beneath an abutment y on the ram to prevent accidental downward movement thereof. With the parts in the positions shown, to start the press, the guard m is pulled down and this removes the hooked end x from the path of the abutment y. While the ram is in motion, this hooked end bears against the abutment y to prevent the guard from being raised. As a further precaution against accidental movement of the ram, the pre-filler valve h may be held open until the lower end of the abutment y has been moved past the upper edge of the hook x. For this purpose, the valve is connected by a rod 2 to a lever 3 pivoted at 4 and having at one end an actuating rod 5. The other end is connected by a rod 6 to a bell-crank lever 7 one arm of which carries a roller 9 adapted to bear against a cam 10 on the ram which serves to keep the valve h open until the lower end of the abutment y has moved past the upper edge of the hook x and it will be held there without any building-up of pressure in cylinder d, if the guard m has been inadvertently left in the ,upper position. Alternatively, a relief valve on the pipe supplying pressure to the cylinder d may be connected to the guard mechanism in such manner as to be open until the guard is in its operative position.

Title: Improvements in treating textiles and oils therefor
IPC: H04N5/08
Filed: 1937-04-20
Abstract: Textile oils containing unsaturated compounds are rendered less liable to oxidation by heating with sulphur to such a temperature, usually below 200 DEG  C., as to form a not unduly darkened oil which when cold does not stain metals and contains less than 1 per cent of sulphur.  This may be effected by: (1) dissolving the sulphur in the oil at a lower temperature, e.g. below 125 DEG  C. and then heating to the necessary temperature, e.g. 180 DEG  C.; (2) adding a concentrated solution of sulphur in the oil or in a volatile solvent such as carbon-disulphide to the main body of oil held at the necessary temperature, e.g. 180 DEG  C.; or (3) adding to the oil maintained at or afterwards brought to the necessary temperature, e.g. 180 DEG  C. sulphur in a form which dissolves readily at this temperature; a suspension of fine crystals obtained by dissolving sulphur in a portion of the oil at below 125 DEG  C. and cooling rapidly to 20 DEG  C. is suitable.  Oils treated include olive oil, arachis oil, sperm oil, oleic acid, oleyl alcohol, diglycol oleate, and polymerized cyclohexanol oleate.  In an example, 5 lb. of sulphur is dissolved in 100 lb. of arachis oil at 110 DEG  C. and the solution, or the suspension obtained by rapidly cooling to 20 DEG  C. is added to 1900 lb. of the arachis oil which is maintained at 200 DEG  C. for 30 min. or is at room temperature and is raised after the addition to 200 DEG  C. for a few minutes.  Specifications 254,303, [Class 91], and 462,665 are referred to.
