Title: Apparatus usable in detecting or measuring gas or dust
IPC: F04B9/12
Filed: 1973-03-15
Abstract: 1381066 Gas analysis DRAGERWERK AG 15 March 1973 [15 March 1972] 12639/73 Heading G1B [ Also in Division F1] Apparatus for use in gas analysis comprises a chamber 1 to which the gas can be admitted through a measuring device 4, the chamber having a movable wall 19 which at one side is acted upon by springs 6 and at the other side by a piston 7a controlled in its movements by a compressed air supply 10. As shown, the compressed air supply 10 is connectable by way of a two-way valve 8 to a cylinder 7 in which the piston 7a is movable, the valve 8 being actuated by a rod 15 having stops 16, 17 for abutment with the movable wall 19. A counter 20 or programmed device may be provided. In use, and with the valve 8 set to connect the supply 10 to the cylinder 7, the piston 7a is urged upwardly to move the wall 19 towards a fixed wall 2 of the chamber and exhaust gas in the chamber through a non- return valve 5. When the wall 19 reaches stop 17 the rod 15 is moved to actuate valve 8 and counter 20. As a consequence, the supply 10 is cut off and air in the cylinder 7 can exhaust to atmosphere through orifice 14 due to the action of a compression spring 7b on the piston 7a while springs 6 urge the walls 2 and 19 apart so that gas is drawn into the chamber through the measuring device 4. When the wall 19 contacts the abutment 16, the valve 8 is actuated again and the cycle is repeated. The springs 6 and 7a are such that the piston 7a loses contact with the wall 19 when the chamber is expanding and the piston is retracting into the cylinder.

Abstract: 796,859. Secret transmission. ZENITH RADIO CORPORATION. Dec. 13, 1954, No. 12670/56. Divided out of 796,858, [Group XL (b)]. Class 40 (4). The audio signal AA, Fig. 2, accompanying a television video signal coded for secrecy as described in the parent Specification is itself coded by being subjected to phase reversals as indicated at y under the control of a coding signal BB with transitions synchronized by the television line pulses DD. At a receiver, the signal is subjected to compensating phase reversals so as to restore it to its original form CC, the operation resulting, however, in transient interfering signals x occurring at the transitions. To remove the interference, the signal CC, Fig. 3 (shown here on an expanded time axis) is sampled by superaudible pulses FF timed so as not to coincide with the transitions, the pulses being derived from line synchronizing pulses DD by first multiplying them in frequency as indicated at EE and then subjecting them to a delay slightly exceeding the duration of a pulse. The sampled signal takes the form shown at GG and is smoothed by a low-pass filter to derive the original audio signal free from interference as shown at HH. The circuit for performing the sampling operation, Fig. 4 (not shown), comprises two reversely-connected triodes connected between the audio input circuit and an output capacitor, the triodes being driven to conduction by pulses FF applied with appropriate polarity to their grids to allow the capacitor by charging or discharging to acquire the potential level of the audio signal.

Title: Improvements in hand grenades
IPC: F42C1/06
Filed: 1940-12-19
Abstract: 546,615. Bomb fuzes. ZUBKO, J. (Granat Soc. Anon., Kula, W., and Szulc, W.). Dec. 19, 1940, No. 12741. [Class 9 (i)] A laterally-withdrawable safety-bolt j, k for a hand grenade is interposed between the firing pin g and percussion cap h. The two parts of the safety-bolt are pivoted together at j', the part j being normally supported in alignment with the part k by a tongue d'. The bolt is slidable in a tube e and is under the extraction impulse of a bowspring n, which passes through the head of the bolt. A second spring o carried by the usual safety-arm m bears upon the head x of the bolt, so that when the safety-pin r is withdrawn and the grenade is thrown, the springs n, o operate to reject the arm m and start withdrawal of the bolt j, k, Fig. 2, the withdrawal being completed by the pull on a string u connecting the bolt to the arm m. Should the grenade be dropped or receive an impact or jerk while the bolt j, k is only partly withdrawn, the part j is tilted into the position shown in Fig. 2, and prevents the contact of firing pin and percussion cap. The corner k' of the part j becomes engaged with the end of the tube e and further withdrawal of the bolt is prevented. The firing pin is formed at the base of a conical member f which is pressed outwardly by a spring l. A free weighted mass i is seated in the member f so as to operate the firing pin under oblique impacts. In the event, however, of axial impact by the top end of the grenade, a charge-container t in which the percussion cap h is carried, is impelled forwardly against the firing pin. The weight i may be made of material which ignites, melts, or disintegrates when the grenade bursts.

IPC: H03K5/135
Filed: 1956-04-27
Abstract: 860,225. Transistor and thermionic discharge tube gating circuits. ELECTRIC & MUSICAL INDUSTRIES Ltd. April 29, 1957 [April 27, 1956], No. 12941/56. Class 40 (6). In a circuit in which negative-going clock pulses are applied to terminal 1, the pulses are fed out over capacitors C3, C4 in accordance with the polarity of the waveform applied to terminal 2. The transistors T1, T2 are arranged with a common emitter load R3 so that when one is conducting the other is cut off. Assuming the waveform at terminal 2 to be positive, the transistor T1 is cut off and the collector potential falls towards the negative supply so that the diode D1 is just conducting and a negativegoing clock pulse is fed over capacitor C1, diode D1 to the capacitor C4. In a similar manner, when the potential of terminal 2 is negative, transistor T1 conducts to bias off diode D1 while transistor T2 is rendered non-conducting so that diode D2 conducts and the clock pulses are fed out over capacitor C3. The outputs may be applied to a bistable circuit 3 to give a regenerated pulse. Positive-going clock pulses may be employed with the diodes D1, D2 reversed in polarity. The transistors may be replaced by thermionic discharge tubes.
