Abstract: 1,166,977. Detecting RF fields; locating leaks in waveguides. UNITED STATES ATOMIC ENERGY COMMISSION. May 20, 1968 [June 26, 1967], No. 24016/68. Heading G1U. [Also in Divisions G4, H3 and H4] A circuit for producing a chirp note when an RF field is present comprises a coil L tuned by CI to the RF field, e.g. 200 MHz, (continuous or pulsed) the picked-up signal being rectified by DI to change C2. At a predetermined level depending on the setting of P the unijunction Q1 will fire and apply pulses to transistor Q2 at a frequency depending on the RF level. At each pulse capacitor C4 changes and turns on Q3, the time constant of C4 and R2 determining the duration of the chirp. When Q3 conducts, capacitor C5 alternately changes through R3 and discharges through a second unijunction Q4 to produce a chirp A. F. signal at a frequency depending on R3. This signal is amplified and fed to a Piezo-electric or other loudspeaker S. Diodes D2 and D3 prevent the associated transistors from being cut off by large signals. The circuit may be used as a personnel monitor for dangerous R. F. fields or for locating leaks in waveguides or cooling lines.

Title: Improvements in or relating to the proportioning of gas and air for combustion in internal combustion engines
IPC: F02M21/00
Filed: 1933-08-31
Abstract: 424,790. Regulating. BROWN, C., 19, Trinity Road, Birchfields, and AMAL, Ltd., Holford Works, Perry Barr, both in Birming- ham. Aug. 31, 1933, No. 24166. [Class 7 (vi)] In means for proportioning the supply of gas and air to an engine working with gas obtained from a compressed supply fitted with one or more reducing-valves, an increased quantity of gas is automatically supplied to the engine when the mixture throttle valve is suddenly opened, by connecting the last reducing-valve to a diaphragm exposed on one side to induction-pipe pressure, and by initially restricting the air supply. Compressed gas from a container 1 passes through a reducing-valve 3, and then through a second reducing-valve 6 to a pipe 13 leading to the mixing chamber 14, which is also connected to the air intake pipe 26. This pipe is connected to a chamber 25, the air inlet to which at 20 is controlled by a valve 19 connected to a diaphragm 17. The space between this diaphragm and the diaphragm 7 of the reducing- valve 6 is connected by a pipe 28 to the air intake. When the mixture throttle 16 is suddenly opened, the increased suction in the pipe 28 opens the valve 6 to pass a greater quantity of gas for rapid acceleration. As the valve 19 also moves to the left, the air is at first still restricted at 20, but as the engine accelerates the valve 19 moves further to the left so as to lessen the restriction in the air supply.

Abstract: 742,137. Dampers. DICKINSON, F. G. Sept. 1, 1954 [Sept. 1, 1953], No. 24177/53. Class 126. An air-inlet device for controlling the draught to a domestic fireplace, comprises a rectangular frame for application to a hole in the floor and a damper which, in the closed position, is engaged under the frame and is urged against the same by a spring, the said damper engaging the frame on two opposite sides by formations which permit the damper to be moved free from either of the said sides of the frame so that it can swing upwardly about the still engaged side into an open position. In the damper arrangement shown a square hole 7 in the floor is edged by a frame 1 substantially of inverted channel form two opposite sides of the frame having shallow depending walls 8 whilst the other two sides have deep depending walls 6. The walls 6 are joined together by side struts 27 and a bridge piece 14 and each is formed with a V-shaped slot 24 with a wide bottom portion 25. The damper plate 9 is square and along each of two opposite edges is formed a channel 10 in which, when the damper is in its closed position within the frame, a frame wall 8 engages. Each of the other edges of the damper is formed with a deep flange 22 carrying a pin 23 which, when damper and frame are in interengagement, engages one of the slots 24, 25. The damper in its closed position is engaged under the frame and is urged against same by a spring 13 disposed in a telescopic housing the upper part 18 of which is pivotally connected to the damper whilst the lower part 15 is detachably carried through spigot means by the bridge piece 14. To open damper fingerholds 26 are engaged and the damper moved downwards and sideways to disengage one channel 10 from its frame wall 8. The damper is then released and the spring causes it to move upwardly each pin 23 sliding along the appropriate branch of the slot 24 depending upon which channel 10 and wall 8 has been disengaged.

Abstract: 1,068,318. Extrusion - blow moulding. OWENS-ILLINOIS Inc. June 11, 1964 [June 12, 1963], No. 24194/64. Heading B5A. [Also in Division B8] A shaped plastics article is formed in two stages from material containing an expanding agent, expansion being prevented during the first stage but allowed during the second stage so that part of the article is cellular and part non-cellular. In one application the invention is described as applied to the forming of a bottle by an extrusion-blow moulding process wherein the hot plasticized plastics material in the cavity (23) is injected by a reciprocating sleeve (25) into the space defined by a partible neck mould (26) and a hollow core (27) which then rise to allow extrusion of the tubular extrudate which is severed by a blade (31). The material within the neck mould is substantially unexpanded but the foaming agent expands the extrudate. A blow mould then closes on the extrudate which is blown to conform to the mould cavity. In a modification the reciprocating injection sleeve (25) has a groove (32) which by rotation of the sleeve can be brought into register with the supply channel (24). In another example, a bottle cap is formed in an injection mould (33). The injecting plunger (38) injects a measured quantity of plastics material into the mould and the plunger is retained in the mould while the material in contact with the mould wall sets. The mould then moves upwardly to allow the foaming agent to expand the central part of the cap. It is suggested that low or high pressure polyethylene or polystyrene may be used.
