Title: Improvements in or relating to electric discharge tubes
Inventor: DELORAINE EDMOND MAURICE
IPC: H05H1/00
Filed: 1947-11-11
Abstract: 648,541. Telephone instruments. STANDARD TELEPHONES & CABLES, Ltd. Nov. 11, 1947, No. 29987. [Class 40 (iv)] [Also in Groups XIX, XL (a) and XL (c)] A microphone in which motion of the diaphragm is caused to modulate pulses applied to electrodes of the device comprises a cold cathode gas-filled electric discharge tube (see Group XL (a)). The microphone has a moulded case 44 enclosing a gas tube 40 having a glass envelope 41 closed at one end by a flexible diaphragm 42 sealed to flanges 43. The electrode system comprises an anode wire 45, a cathode wire 46 and a further cathode wire 48 forming a gap 49 with the diaphragm 42. A first pulse from the generator 51 fires the gap between 45 and 46. Ionization from this discharge reduces the striking potential of gap 49 which fires on the second pulse. The third and subsequent pulses fire both gaps. The delay between the application of a pulse and the firing of gap 49 depends on the amplitude of the applied pulses and on the length of gap 49. A series of output pulses is thus obtained from transformer 52 at time intervals depending on the length of gap 49. A steady battery voltage may be applied to the electrodes so that gap 49 fires automatically after the firing of the first gap, arrangement being made to extinguish the discharge subsequently. In a modified arrangement, an additional anode is provided to co-operate with cathode 46 and form a permanently discharging gap which controls the general level of ionization in the tube.

Title: Improvements in or relating to parachute harnesses
Inventor: MITCHELL JOHN ROTHWELL
IPC: B64D17/22
Filed: 1965-07-09
Abstract: 1,081,476. Parachutes. G.Q. PARACHUTE CO. Ltd. May 18, 1966 [July 9, 1965], No. 30068/65. Heading B7G. A harness is connected to the rigging lines of a parachute by risers 24, 25, 26, 27 drawn together into a single strand by holding means which break or part when a predetermined force acts thereon due to e.g. the parachute being deployed, to thereby allow the risers to separate. The provision of the holding means ensures that the legs of a tumbling parachutist do not become entangled with the risers during deployment. The holding means may comprise a flap 28 wrapped round the risers and connected together by pieces of tape or studs 29 which grip when pressed together. In addition to the flap 28 a web 30 encircles the risers and is held in position by a pin 35 carried at the end of a strap 34 threaded through a ring 37 on the riser 25 so as to automatically withdraw the pin when the flap is separated. In a modification, Figs. 1, 2 and 3 (not shown), the flap extends, first round one pair of risers, and then round a second pair of risers, the two pairs of risers being separated at the harness end. The risers are also held together in pairs by ties which break when subjected to a certain stress. In a second embodiment the risers are held together simply by pieces of tape thereon which grip when pressed together.

If a shuttle 50 remains in the shed springs 31 push out the loose reed 11 before beat up. The reed 11 is supported on a member 25 attached to a number of pivoted levers 26, at least one of which has a roller 29 running on a lever 32 as the sley 16 reciprocates. The lever 32 is supported by a pawl 37 attached to a pivoted member 36 bearing against a spring 41. At back centre, the spring 41 is strong enough to overcome the action of the springs 31 and, as the sley moves forward so that the roller 29 runs on the lever 32 and the springs 31 would tend to overcome the spring 41, the lever 26 bears on a pivoted member 42 to cancel the action of the springs 31and to lock the reed. If, as the sley moves forward, a shuttle 50 jams in the shed, the reed is moved slightly back by the shuttle, the member 36 slightly compresses the spring 41 so that the pawl 37 is released by a stop 40 and the springs 31 are allowed to push out the reed 11 upon collapse of the lever 32.

In converting arrangements employing mercury arc valve rectifiers, to reduce the rate of increase of reverse voltage applied to the valve during a blocking period, a saturable reactor is connected in series with the valve and a resistance-capacity unit connected across it. Fig. 1 shows saturable reactors 11, 12 and resistancecapacity units 7-8, 9-10 in an arrangement in which the supply passes alternately through one load 4 then the other 5 in reference to a frequency applied to the grids. With valve 2 conducting, capacitor 6 charges with the righthand plate positive and the left-hand plate negative. When valve 3 conducts the capacitor reverse voltage initially appears across saturable reactor 11 but is subsequently transferred to capacitor 8 and so valve 2, after allowing time for the ionization in valve 2 to disappear. Resistor 13 biases the reactor into saturation during a non-conducting period. A similar saturable reactor and resistance-capacitance unit may be used in a pulse converter (Fig. 2, not shown) in which a D.C. voltage is lower than the D.C. supply voltage is maintained across a load by periodically disconnecting the load by means of a mercury arc valve, the valve ceasing to conduct when it receives a back-voltage from the capacitor in parallel with the load.

Potato diggers and harvesters.-A potato-digger mounted on wheels 3 has a frame 1 carrying a digger blade 5 and a roll 4 for flattening the tops of the plants. The potatoes are lifted by a grating 6 on to a wide mesh conveyer 7 through which they fall to a smaller-meshed conveyer 8 arranged so that the space between the top runs of the conveyers increases towards the rear. The conveyer- 8 is within the convever 7 and travels at a higher speed than the latter to facilitate detaching the potatoes from the tops. From the conveyer 8 the potatoes fall to a skid 13 which transfers them to a. conveyer consisting of a chain of bent iron bars which delivers the potatoes to a cart driven alongside the machine.
