Title: Method of treating tool steel die materials
IPC: C21D1/18
Filed: 1980-07-29
Abstract: In a method of hardening pilger dies to provide a hard case containing residual compressive stresses and tough body, the tool steel die is heated to the austenitizing temperature range, followed by selectively removing heat from the die at a predetermined faster rate in the direction of the desired case than the rate of heat removal from the balance of the die, and thereafter tempering the die.

Title: Improvements to colour television decoding apparatus
IPC: H04N9/78
Filed: 1980-12-11
Abstract: A discriminator circuit for detecting horizontal colour boundaries in picture areas of a colour television picture to be formed from a colour television signal incorporating quadrature modulated chrominance information comprises first comparator means (106) for comparing chrominance components of parts of the video signal relatively delayed by an even number of line periods, and a second comparator (135) for comparing the chrominance components of parts of the video signal relatively delayed by an odd number of line periods.   Each comparator means is associated with means (101, 102 or 140) for cancelling the phase difference between the chrominance sub-carriers of the respective signals between which a comparison is to be made. The output from the discriminator circuit may be used to control comb filtering of the video signal to remove chrominance information from the main luminance signal by providing that the comb filter is disabled when a signal output occurs from either one of the two comparators (106, 135). Alternative filtering means, for example a bandpass filter may then be used in place of the comb filter in picture areas where the use of the latter would be inappropriate. <IMAGE>

Title: Control valves for hot fluids
IPC: G05D23/12
Filed: 1981-07-03
Abstract: A hot fluid flow control valve having a valve member (6) that is carried by an element (5) that flexes for moving the valve member to open or close the valve; the flexible element being subjected to vapour pressure of control fluid (10) that is heated by the fluid, flow of which is to be controlled by the valve, such that whilst the flow line fluid is at or below a predetermined temperature said vapour pressure is at a value determined by the temperature of the flow line fluid such that the valve is in one of an open or a closed state; the control fluid being contained in a pipe arrangement (4) that also contains gas (11) that is inert to the control fluid. For operating the valve this gas is heated, by an element (9), to expand it and hence the vapour pressure is raised to flex the element (5) to move the valve member (6) to the other of said open or said closed state. <IMAGE>

Title: Crushing machinery
Inventor: PARRY JOHN PIERCE MARTIN
IPC: B02C18/00
Filed: 1982-03-31
Abstract: A crushing machine comprises a crushing member 20 which is semi- cylindrical in shape, and mounted to permit pivotal movement. Extending downwardly from the crushing member 20 are elongate support members 24, which carry at their lower ends a weight 26. Application of force to the weight, causes it to oscillate the pendulum, causing the crushing member 20 to rotate back and forth about said axis. The crushing member 20 cooperates with a stationary member 28, which is also semi-cylindrical. When raw material e.g. clay for making bricks is loaded into the machine, via a chute 30, the material passes down into the nip between the crushing member and the stationary member, during which the material is reduced in particle size. If tramp material approaches the nip the stub shafts (22) of the member 20 permit the member to lift in mountings (16 Fig. 2). <IMAGE>
