Abstract: 551,798. Relaxation oscillators ; television. PHILCO RADIO & TELEVISION CORPORATION. Sept. 8, 1941, No. 11455. Convention date, Sept. 17, 1940. [Classes 40 (iii) and 40 (v)] In a system in which recurrent pulse signals control a blocking oscillator, a condenser-relaxation generator or a pulse amplifier and undesired signals are preventing from affecting the operation by utilizing the pulses produced to render the circuit unresponsive during the intervals between the pulses as described in Specification 535,331 a .resonant circuit or means to produce a sinusoidal voltage is provided so that a sine wave is added to the quenching voltage so that the rate of change of voltage is increased. Fig. 2 shows a frequency divider comprising a blocking oscillator 1 in which the free oscillations produced in the circuit 16 are applied to the grid superimposed on the voltage from the condenser 4 which is discharged by resistance 3 and on the pulses from the source e. Fig. 3 shows at a in broken lines the normal exponential decay and in full lines the combination of the applied pulses b and the sinusoidal voltage produced in the circuit 16. In a modification, Fig. 1 (not shown), the resonant circuit is arranged in the anode circuit of a succeeding amplifier and the oscillations are applied to a limiter and further amplifier to form a " microtome " circuit as described in Specification 542,436 so that the positive peaks only are fed back to the cathode of an amplifier which feeds the incoming pulses to the anode of the blocking oscillator. Fig. 4 shows a horizontal deflecting circuit for a television receiver using a gas discharge tube 20 for discharging condenser 21 and an output amplifier 24 feeding the deflecting winding. In this arrangement the resonant circuit 30 is provided in the circuit of the amplifier 19 and actuated by the amplified pulse signals while a wave-form control'tube 26 is provided fed from the screen of the amplifier 24. Alternatively a blocking oscillator may be used with a number of resonant circuits in the cathode lead of a following amplifier and in series with the blocking condenser 4, Fig. 5 (not shown). The invention is also applicable to direct driven deflecting systems such as disclosed in U.S.A. Specification 2,141,343. Fig. 7 shows such a system employing a gas discharge tube which controls the charge and discharge of condenser 40 and a resonant circuit 36 which biases the amplifier 37 during the intervals between desired pulses so that interference such as the double horizontal pulses inserted before and after the vertical pulses is eliminated.

Title: New sulphur containing compounds and process for the production thereof
Filed: 1956-04-16
Abstract: The invention comprises compounds of the formula R-S-CH2-CH2-NA-alkylene-NA-CH2-CH2 -S-R where A is H, alkyl or carboxyalkyl, R is hydrogen or aralkyl and the alkylene group has 2-4 carbon atoms linking the nitrogen atoms; also salts of the above. These are made by reacting R-S-CH2-CH2-NH2 with a reactive glycol derivative (e.g. a dihalide) and an alkylating or carboxyalkylating agent in either order, and if desired splitting off the aralkyl group by hydrolysis or hydrogenolysis, e.g. with sodium and liquid ammonia. The groups A can be introduced with an alkyl halide, a halo-fatty acid (or ester, subsequently hydrolysed), or with formaldehyde and formic acid if A is to be methyl.  The products are complexing agents for heavy metals (e.g. cadmium).  Examples show the preparation of N : N1-bis-(2-benzylthioethyl)-ethylenediamine dihydrochloride, N : N1 - bis-(2 - mercaptoethyl) - ethylenediamine dihydrochloride, N : N1 - bis - (2 - benzylthioethyl)-ethylenediamine - N : N1 - diacetic acid, N : N1-bis-(2-mercaptoethyl)-ethylenediamine-N : N1-diacetic acid, N : N1 - bis - (2 - benzylthioethyl)-trimethylenediamine dihydrochloride, N : N1-bis - (2 - mercaptoethyl) - trimethylenediamine dihydrochloride, N : N1 - bis - (2 - benzylthioethyl) - trimethylenediamine - N : N1 - diacetic acid (and perchlorate), N : N1-bis-(2-mercaptoethyl) - trimethylenediamine - N : N1 - diacetic acid, N : N1 - bis - (2 - benzylthioethyl) - N : N1-dimethyl - ethylenediamine dihydrochloride, N : N1 - bis - (2 - mercaptoethyl) - N : N1 - di - methyl - ethylenediamine dihydrochloride, N : N1 - bis - (2 - benzylthioethyl) - N : N1 - di-n-hexyl-ethylenediamine and the corresponding mercapto compound. The analogous N : N1-dicetyl compound is made similarly.  The mercapto compounds are isolated by conversion into mercuric salts and regeneration with hydrogen sulphide.  N-(2-benzylthioethyl)-glycine is obtained (as hydrochloride) from 2-benzylthioethylamine and ethyl chloracetate, the ester group being saponified.  2 - Benzylthioethylamino - hexane is prepared from 2-benzylthioethylamine and n-hexyl bromide.

Title: Improvements in or relating to linear-dimension gauging devices
IPC: G01B13/10
Filed: 1943-07-16
Abstract: 579,059. Lineardimension gauges. SHEFFIELD CORPORATION. July 16, 1943, No. 11598. Convention date, Aug. 15, 1942. [Class 106 (ii)] In a linear-dimension gauge of the kind in which the rateof flow of a fluid escaping from a nozzle is used to indicate the distance between the nozzle and the workpiece and hence a dimension of the latter, nozzles 34, Fig. 2, are fixed in a body 30 (in this example a body is a cylinder for gauging internal dimensions of tubes) having wearresisting projections 31. The projections may be of tungsten carbide and are formed as ribs extending on each side of the nozzle in a direction parallel with the axis of the body 30. Two nozzles 34 are situated at the ends of a diametral air-supply passage 33, the projections 31 upstanding above the nozzle faces to space the latter from the face of the workpiece. The nozzle faces 39, Fig. 5, are curved to a radius concentric with that of the cylinder 30 and the end 40 is flared slightly. In a modification, Fig. 6, for gauging rifled barrels, the projections comprise hard radially arranged inserts 53 in sleeves 46 rotatable on the body 42 and adapted to enter the rifling grooves. Other inserts (not seen in Fig. 6) are provided in the body 42 in the plane perpendicular to the paper and containing the nozzles 44. As the body 42 is inserted into the barrel, the sleeves 46 can rotate relative to the body to accommodate variations in the helix angle of the rifling. In a further modification, a cylinder similar to the cylinder 30 is provided with radial projections so spaced that a projection, a nozzle and a further projection are arranged in a helix corresponding with the rifling helix. Compressed air or other fluid is supplied to the nozzles through a regulating valve 20, Fig. 1, rate-of-flow gauge 16, pipe 13 and shut-off valve 12. The rate-of-flow gauge comprises a tapered tube 16 provided with a float 17 which takes up a position dependent upon the rate of flow. The range of the rate-offlow gauge can be varied by operating a byepass valve 27 which permits a greater or less proportion of the air passing to the nozzle to byepass the gauge.

Title: Improvements in Control Mechanism.
Inventor: BRUNTON JOHN LOCKHART
IPC: B63G8/22
Filed: 1918-07-18
Abstract: 130,126. Brunton, J. L., and Brunton, W. P. July 18, 1918. Valves controlled by pilot or relay valves; interlocking.-Relates to selective control mechanism applicable, for example, for operating the driving gears of military tanks, the. valves for flooding compartments in ships, or like purposes. A shaft 10, Fig. 1, carries two levers 11 turning on sleeves 111 capable of sliding on the shaft. The levers are operated by handles 112 and carry pawls 113, Fig. 2, engaging with teeth 114 on the sleeves 111 to hold them in position. Each lever may operate one of a number of rods 14 attached to Bowden wires 12 which operate the control mechanism. A gate 15 prevents the lever from turning except when it is in a position to engage one of the rods 14. The Bowden wires are arranged in pairs, each of a pair being connected to one of the control valves so that a valve may be operated from either side of the operator. In order to prevent contradictory gears from being put into operation at the same time, studs 142, Figs. 2 and 3, are fixed on some of the rods 14 which engage in slots in plates 16, so that when a rod 14 is raised, the plate 16 slides and engages with a stud on one of the other rods to prevent the latter from being raised. The Bowden wire 12 operates a lever 17, Fig. 6, which operates a rod 18 carrying a valve 181. The movement of this valve to the left displaces a ball valve 183 and allows pressure water from the pipe 20 to pass into the pipe 133 and thence to a control cylinder. At the same time, the valve 181 is seated, and the exhaust through the pipe 22 is closed. On releasing the Bowden wire, the valve 181 is opened to exhaust, and the valve 183 is closed. When the ball valve is closed, the pressure water normally passes through the passage 132 to the smaller end of a differential ram, keeping it at one end of its stroke, but when the ball valve is opened the pressure water passes also through the passage 133 to the other end of the ram, and displaces it in the opposite direction. The gears or valves are thus operated selectively by these rams.
