Filed: 1953-10-09
Abstract: 773,527. Waveguide couplers. BRITISH THOMSON-HOUSTON CO., Ltd. Oct. 29, 1954 [Oct. 9, 1953], No. 27855/53. Class 40 (8). An arrangement for coupling a rectangular waveguide W to auxiliary guide, e.g. a circular guide, comprises two or more similar holes A, B, &c., spaced apart along the centre-line of the broad face of the rectangular guide for obtaining a longitudinal component of current, and a longitudinal slot C offset from the centre line and arranged symmetrically with respect to the holes so as to obtain a transverse component of current in time quadrature with the longitudinal component. In the embodiment shown the distance l between the holes AB is chosen to give a substantially constant longitudinal current component over the working range. The length l1 of the slot C is then chosen to give a transverse current characteristic which coincides as nearly as possible with the longitudinal current characteristic over the working range. This may be done by choosing the length of the slot so that it is resonant at about half the working wavelength. The Specification contains a brief mathematical discussion of the invention. Specification 592,224, [Group XL], is referred to.

Title: Derivative of carboxy methyl cellulose
Inventor: ROSE LESLIE
IPC: C08B15/10
Filed: 1963-07-18
Abstract: A water-insoluble derivative of carboxymethyl cellulose is made by adjusting the pH of a salt-contaminated sodium carboxymethyl cellulose to 4.5-5.5, thereby generating a plurality of free carboxyl groups, heating the sodium carboxymethyl cellulose at a temperature in excess of 100 DEG  C. to condense hydroxyl groups with a sufficient proportion of the free carboxylic acid groups to render the derivative insoluble in water, and washing the derivative in water.  The heating temperature is preferably 115-130 DEG  C.  The insolubilization resulting from the formation of intermolecular or intra-molecular ester groups, enables the sodium carboxymethyl cellulose to be freed from by-products formed in its synthesis, by water-washing only, without use of alcohol.  The insolubilized material may be stored as such or may be treated with heated caustic soda solution to form a solution of purified sodium carboxymethyl cellulose

Title: Improved control for fluid-pressure servo systems
IPC: B64C11/38
Filed: 1952-11-13
Abstract: 714,903. Fluid-pressure servomotor-control systems. GENERAL MOTORS CORPORATION. Nov. 13, 1952 [Nov. 30, 1951], No. 28595/52. Class 135  A fluid-pressure servo system comprises a control valve for fluid to and from a double-acting servomotor, a check-valved passage a lowing substantially unrestricted flow to one side of the motor and a variably restricted passage bye-passing the check valve and controlling the flow from that one side. The servosystem, e.g. for a variable pitch propeller 6, comprises a pump 1, a valve 19 controlling the pump output pressure in accordance with the load on the servo-piston 48, a control valve 39 moved in opposite directions by alternatively energized solenoids 37, 38 under, e.g., a speed control such as described in Specification 676,390, and an assembly of a check valve 55 and a pressure regulating valve 77 controlling the connection between the control valve and the lower side of the piston. The propeller is of the type which tends to shift to a decreased load position, i.e. the piston tends to move downwardly. When the valve 39 moves to the right the top of the piston and pipes 43, 45 are open via port 41 to a sump 7, and pressure fluid passes unrestrictedly via pipe 12, ports 34, 40, pipe 42, check valve 55, port 65 and pipe 42a to the bottom of the piston to increase the load on the propeller. A shuttle valve 53 closes the pipe 45 and opens a pipe 44 connected to pipe 42 so that the pressure supplied to the bottom of the piston acts via pipe 33 on a piston 29, together with a spring 17, against the pump outlet pressure acting via pipe 11, on top of the piston 29 to control the leak-off port 21. When the control valve moves to the left to move the piston in the decreasing load direction the check valve closes and the fluid exhausted from below the piston is throttled by passing through pipe 78, port 73 controlled by a land 62 on the piston valve 77, and passage 58 through the piston to produce a constant pressure in a chamber 72. A relief valve 18 limits the maximum outlet pressure.
