Abstract: 766,546. Measuring heat quantities. GAS COUNCIL, and GOODERHAM, W. J. Oct. 28, 1954 [Oct. 28, 1953], No. 29837/53. Class 97(3) To measure the calorific value of a gas, water and a gas sample are fed at substantially constant rates, the gas being burned at a burner 20 and the heat being transferred to the water partly in a heat exchange unit 44 and partly, from the effluent gases, in a unit 48. The temperature of the efluent gases are measured by a thermometer 30, the temperatures of the water before heating and after heating and mixing in a coil 46 are measured by thermometers 22, 23. The units 44, 45 and the coil 46 are contained in a silvered evacuated calorimeter vessel 21. The water is contained in a reservoir 14 while a reservoir 13 contains mecury. Both are lifted simultaneously by a screw jack driven by a motor 12. The water is thereby fed to the calorimeter while the mecury displaces the gas from the sampling bulb 15 which is also fed, being saturated with water vapour by passage over wet blotting paper 19. Water and gas pass through tubes in a temperature stabilizer 18. Air for the combustion enters at 24 and passes through a saturator 26. The reservoirs 13, 14 and the sampling tube 15 may be replaced by syringes with plungers simultaneously operated by a motor driven screw to pass the water and gas sample to the calorimeter.

Filed: 1935-10-29
Abstract: 465,461. Electric signalling systems. ROBINSON, J. Oct. 29, 1935, No. 29881. Addition to 435,621. [Class 40 (i)] [Also in Groups XL and XXXVI] In a wireless system comprising a transmitter frequency-modulated in accordance with atmospheric pressure at the transmitter as described in the parent Specification, the receiver comprises means for varying the tuning cyclically through a range of frequencies, an indicator moving in synchronism with the tuning variation, the received signals rendering the indicating device operative to give a visual indication of the signal. Fig. 1 shows a superheterodyne receiver in which the frequency of the local oscillator 11 is cyclically varied by condenser 14 driven by motor 16, the shaft of which also rotates a piezo-electric resonator 22 in a gas-filled tube. The crystal is fed from the output 12 through sliprings 20, an apparently stationary indication of 22 being obtained against the scale 19 due to stroboscopic effect. Alternatively a neon tube may be used; or a relatively stationary lamp may have its flashes reflected from a mirror at the periphery of a rotating disc behind the scale, Figs. 2-4 (not shown). In Fig. 5 the rectified receiver output is applied to a control electrode 33 of a cathode-ray tube so that the electron stream is only permitted when the signal voltages are impressed on 33. The cathode beam is rotated by deflecting coils 37, 38 fed from a generator 39, 40, 41 mounted on the shaft of motor 16. The beam normally rotates in synchronism with the condenser 14, but is inhibited except at the point where the maximum receiver response occurs in the rotation of 14. A direct indication of the tuning is thus given. The invention is intended for systems for use in aircraft, to enable barometric pressure or height of one aircraft to be transmitted to another. Specifications 9181/12, [Class 37], 249,069, 325,232, and 325,481, [all in Class 40 (v)], are referred to.

Title: Cylinder locks
IPC: E05B27/00
Filed: 1976-07-19
Abstract: The lock cylinder has a key slot (14) for receiving a flat key and two rows of pin tumblers (12). The pin tumblers (12) are mounted displaceably in cylindrical bores (11). The longitudinal mid-plane of the key slot (14) serves as a reference plane for the arrangement of the tumbler-pin bores (11). One row of tumbler-pin bores is located on one side of the longitudinal mid-plane and the other row of tumbler-pin bores is located on the other side of the latter, the longitudinal axes of the bores extending parallel to one another and to the longitudinal mid-plane of the key slot. On the flat key, therefore, the rows of key wards are located on a narrow side of the key. With a conventional size of the lock cylinder, this arrangement makes it possible to provide a plurality of pin tumblers with a large number of sufficiently deep step jumps, so as to afford a very large number of possibilities of variation guaranteeing better safety against unauthorised unlocking. <IMAGE>
