Title: Improvements in or relating to rotatable couplers for radar apparatus
Inventor: RIDGERS CHARLES EDWARD SYDNEY
IPC: H01Q3/04
Filed: 1955-03-30
Abstract: 788,670. Radio-frequency couplings. DECCA RECORD CO., Ltd. March 13, 1956 [March 30, 1955], No. 9340/55. Class 40 (7). The invention relates to rotatable couplings of the type used to feed intermediate frequency radar receiver signals from the rotatable radar head to the static part of the system. According to the invention such a coupling is arranged to have both inductive and capacitive coupling elements. Its bandwidth is thereby increased and it can readily be arranged to accept signals from, and feed them into, a coaxial line. In one embodiment the fixed part of the coupling comprises a tubular mounting 11 of insulating material carrying internally a cylindrical condenser plate 26. Below the plate 26 the mounting is grooved at 28 and carries a coupling winding 29. Coaxial with the mounting 11 and inside it is arranged the rotatable coupling unit comprising a cylindrical insulating member 10 carrying a second cylindrical condenser plate 14 and a coupling winding 17 in a groove 16. The two cylindrical plates 14 and 26 have lengthwise gaps in them to prevent them forming short-circuited turns and affecting the coupling windings and the windings themselves are wound in opposite directions to each other. As shown in the equivalent circuit of Fig. 5, the input coaxial line 42 has its inner conductor connected to the capacitor plate 14 and to one end of coil 17. The plate 26 and the corresponding end of coil 29 are connected to the inner conductor of the outgoing coaxial line 45. The outer conductors of the coaxial lines are connected to the other ends of their respective coils 17 and 29 which are coupled together by a slipring connection. In Fig. 5, 36 and 37 represent the self-inductance of the coils 17 and 29 and 38 their mutual inductance. A capacitor 41 is preferably arranged across the slip-ring connection to prevent the production of highfrequency noise by imperfect brush contact. Preferably the windings are not resonant within the pass-band of the coupler and the input winding 17 may be tuned to be resonant outside this band partially or wholly by the capacitance (48, Fig. 5) of the input line.

Title: Brewing apparatus for coffee-making machines
IPC: A47J31/40
Filed: 1963-03-08
Abstract: 1,041,251. Beverage-making machines. WURTHEMBERGISCHE METALLWARENFABRIK. March 8, 1963 [March 8, 1962], No. 9341/63. Heading A4D. In an automatic coffee making apparatus, a three stage operation is controlled by movements of a piston 7 in a hydraulic cylinder 6. On actuation of the start button manually or by means of a coin-freed mechanism, coffee grounds are dispensed from hopper 9 into a container 2 having a removable strainer 3. Piston 7 is then set in motion by connecting pipe 19 to the hydraulic fluid supply, which may be the water main, and container 2 is moved into housing 1. Covers 4, 5 are mounted on parallelogram linkages 27 and are maintained sufficiently far apart by compression springs 31 for the container 2 to move freely between them until its supporting yoke 16 touches the end flanges of the covers adjacent springs 31. Continued motion of the piston draws the covers 4, 5 rearwardly and inwardly to clamp the container 2 between them and to seal the upper cover 4 against the sealing ring 37. The piston 7 stops when the limbs 27 are vertical and water flows from a water boiler through pipe 32 to prepare the beverage which flows from hole 34. On completion of this step, the piston is set in motion in the reverse direction to effect unclamping of the container 2 and its reappearance from housing 1. The container is moved a little beyond the hopper 9 and is simultaneously inverted by engagement of helical grooves 23 with bolts 24 so that the used grounds may be washed out by water spray 10. The hydraulic fluid supply to pipe 18 is then cut off and compression spring 26 returns the piston to the position shown in Fig. 1. In a modification (Figs. 7 and 8, not shown) the linkages 27 are replaced by a pin and slot arrangement.

Title: Electrical relay device responsive to small changes of a magnitude such as current or voltage
IPC: H01H50/40
Filed: 1938-03-28
Abstract: 513,125. Electromagnetic relays. ENGLISH ELECTRIC CO., Ltd., and TILSTONE, G. March 28, 1938, No. 9419. [Class 38 (iv)] A relay responsive to small charges of current or voltage comprises an operating coil A, fixed U-shaped magnetic members B, C .... F mounted on the coil, fixed magnetic members B<2>, C2 ... F2' and a rotor having poles B1.... F1 energization of the coil A causes the parts to be so magnetized that the poles B1 .... F1 are repelled by the poles B2 .... F2 and attracted by the poles B .... F. By this means the resultant force acting on the rotor remains substantially unchanged during its rotation. The rotor is biassed, e.g., by a weight N so that its poles tend to engage the poles B<2> ... F<2>. When the current is sufficiently great, the combined repulsive and attractive forces overcome the bias and rotate the rotor into position in which for example contact K engages contact M. The relay may function as a voltage regulator, contacts L, K and M operating regulatory devices to restore the voltage to a normal value in which the rotor occupies a central position. Specifications 315,447, [Class 38 (v)], and 513,066 are referred to.

Abstract: 1461449 Load responsive valves KNORRBREMSE GmbH 4 March 1974 [2 March 1973] 9690/74 Heading F2F In a load responsive valve assembly having a load responsive diaphragm-type piston 4, 12 with a pressure control chamber 13, a valve seal 19 is carried by an element 24 and is co-operable with an inlet valve seat 18, controlling flow from a pressure source to the chamber, and an outlet valve seat 17, controlling flow from the chamber to an outlet 30, the element being controlled by operating means 16 responsive to piston movement, wherein the valve seal is compressible by the seats through a discrete distance, e.g. of 10% of the predetermined maximum stroke of the operating means. Vehicle load changes are transmitted through a plate 5 to a deformable plate 8 or an hydraulic cell which transmits a portion of the load to a piston 11 which in turn acts on the piston 12. If vehicle loading is balanced at a particular control pressure, the seal 19 engages both seats 17, 18. If a load decrease occurs, the spring biased operating means 16 follows downward piston movement to open the chamber 13 to the outlet 30; conversely, upon load increase, upward operating means movement opens the chamber 13 to an inlet 23 from a pressure source. The compressibility of the seal 19 avoids spurious valve opening due to transient shocks &c. The operating fluid may be air or other gases or liquids.
