Title: Improvements in electric periodic wave repeaters and generators
IPC: H04L25/04
Filed: 1939-10-12
Abstract: 538,553. Valve circuits relaxation oscillators. HAZELTINE CORPORATION. Oct. 12, 1939, Nos. 27770 and 27771. Convention dates, Oct. 21, 1938 and Dec. 15, 1938. [Classes 40 (iii) and 40 (v)] A thermionic valve circuit for generating periodic pulsations or for transmitting periodic pulsations with or without frequency division comprises a delay network for periodically sensitizing the valve to the desired periodic pulses, the valve being otherwise insensitive so that undesired and irregular pulses are not transmitted. In one arrangement, Fig. 1, a relaxation oscillator comprising a valve 10 periodically discharging a condenser 11 periodically re-charged through a resistance 13 by a battery 12, is fed from a synchronizing source 18 with pulses 1, 2, ..., Fig 2a, and the output of the valve is fed back through a delay network 24. The action of the condenser 11 and resistor 13 is supplemented and may be replaced by the action of the input condenser and leak 15. If the delay in the network corresponds to the time interval between pulses 1 and 4, Fig 2a, the combined input is as shown by Fig. 2d. The valve is biased to be sensitive only to the higher pulses of Fig. 2d, so that the circuit transmits only pulses at that frequency as shown in Fig: 2e, other pulses and any irregular pulses being eliminated. The input and output circuits of the valve may be coupled by inductors 16, 17 ; and if the synchronizing source 18 is omitted, the circuit can be made to act as a generator of pulses. In a modification, the delay network is a reflecting one. Another arrangement, Fig. 5, comprises only valve 10 back-coupled by the delay network 44. In this arrangement an initial pulse, Fig. 6a caused by the closing of the anode circuit is delayed by the network and applied to the input as the pulse Fig. 6b. This causes an anode pulse, Fig. 6c, which is again delayed through the network to form another input pulse, Fig. 6d. The succession of this delayed feedback process ultimately produces the pulses of rectangular wave form, Fig. 6h and Fig. 6i at the anode and grid respectively. In other arrangements, the network is in the output circuit of the valve only, Figs 7 and 9 (not shown), or in the input circuit of the valve only, Figs. 11 and 12 (not shown). Specification 531,712 is referred to.

Title: Improvements in or relating to gas lasers
IPC: H01S3/082
Filed: 1964-07-17
Abstract: 1,017,125. Lasers. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. July 7, 1964 [July 10, 1963], No. 27938/64. Heading H3B. A helium-neon laser which provides an output of 1À15Á wavelength has first and second reflecting systems producing stimulated emission in the gas of 3À39Á and 1À15Á wavelength respectively. The arrangement prevents the usual 0À63Á emission by the neon as a result of transition between the 3s 2  and 2p 4  energy levels, Fig. 1, by causing the 3s 2  level to become insufficiently populated as a result of stimulated emission between the 3s 2  and 3p 4  levels (3À39Á) and the 2S 2  and 2p 4  levels (1À15Á), transition between the 3p 4  and 2S 2  levels being spontaneous. The laser in Fig. 2 comprises a glass tube 1 with discharge electrodes 2, 3 for D.C. energization and quartz end plates 4, 5, the tube being filled with a mixture of about 85% He and 15% Ne at 1 mm. Hg pressure. Dichroic mirrors 6, 7 and 8, 9 are provided within and outside the tube respectively, the mirrors 6, 7 having 99.5% reflectivity at a reflection peak in the proximity of 1À15Á and are sufficiently transparent at 3À39Á to permit laser action at this wavelength. Mirrors 8. 9 transmit about 80% of the 1À15Á radiation and have a reflection in excess of 80% at 3À39Á, the tolerance of alignment of this system not being critical. In a modification, Fig. 3, the tube comprises a quartz block 10 with quartz end plates 11, 12 on which are dichroic layers 13, 14 and 15, 16 for reflecting wavelengths of 1À15Á and 3.39Á. In Fig. 4 (not shown), only two inner reflecting surfaces 17, 18 are provided, the reflection coefficients for these layers being more than 99% for 1À15Á radiation and 80% for 3À39Á radiation.

Title: Improvements in devices for delivering material on to a floor or into a waggon or the like
IPC: B65G69/00
Filed: 1927-10-25
Abstract: 303,234. Woodall-Duckham (1920), Ltd., and Symington, S. Oct. 25, 1927. Shoots.-A shoot for forming a heap of material' in a vehicle or on a floor is provided with a conical or saddleshaped spreader l which is moved aside automatically on lowering the shoot on to the material, to permit delivery to the space between the heaps. The spreader may be moved laterally by raising and lowering the with a continuous flow of material, from the space between two trucks. As shown, the shoot comprises a series of adjustably inclined baffles d mounted in an open framework a adjustable vertically between rollers c on an overhead platform A. The shoot is raised as loading proceeds to receive material from a conveyer n at the level of any of the baffles d. The spreader l is mounted on a plate k hinged at one edge and resting at the opposite edge on bars i hanging from the shoot on links h. When the heaps formed by the spreader are of the required height, the shoot is lowered so that the spreader rests on the material and is tilted as shown in broken lines in Fig. 1. The lowest baffle of the shoot then delivers clear of the spreader to fill the space between the heaps. In loading trucks with a continuous flow of material. the shoot is raised after the operation last described until an arm o on the links supporting the spreader strikes a stop q on the platform, whereby the spreader is moved to the left as shown in Fig. 3 and the shoot delivers only on to the right-hand side l<1> of the spreader. The full wagon is now moved to the right, and when the front end of the next wagon is beneath the spreader the shoot is lowered, moving the spreader to the right as shown in broken lines so that the shoot delivers only to the left-hand side l<2> of the spreader. When the front end of the wagon has passed beyond the spreader, the latter is brought into the normal position. The spreader may consist of an angle frame covered with a length of resilient material.
