Title: Improvements relating to indicating or recording apparatus for gas analysis
IPC: G01N7/04
Filed: 1922-11-17
Abstract: 205,723. Simmance, J. F., and Wood, F. Nov. 17, 1922. Gas analysis.-In gas-analysis apparatus of the type in which samples of gas are automatically and periodically withdrawn into a stationary burette or the like and thence passed through a reagent, the operative fluid is mercury and the displacement of the mercury is effected by the periodic variation in the hydrostatic pressure exerted on the mercury by a column of water or other liquid of comparatively low specific gravity. As shown, mercury, in a reservoir 6 is depressed by the introduction of water through a pipe 8, the water rising in a pipe 10 and the shorter limb 11 of a siphon 11, 12 and exerting a hydrostatic pressure on the mercury. Mercury rises in a tube 5, forcing gas from a burette 1 through the reagent in a vessel 15; mercury rises also in a tube 19 and seals a vent 20 leading from the vessel 15, but this does not occur until the gas from the burette has begun to pass through the vessel 15. The continued ascent of mercury in the tube 5 forces the definite volume of gas thus cut off through the vessel 15 into a measuring bell 17 of known type. The pressure on the mercury is ultimately relieved by the action of the siphon 11, 12, when the descent of mercury in the tube 5 causes a fresh charge of gas to be drawn in through tubes 4, 2. Optional modifications in the apparatus comprise (1) the enclosing of the measuring-bell 17, burette 1, and vessel 15 in communicating water-jackets; (2) the omission of the tube 10, the tube 11 serving to apply the hydrostatic pressure; (3) the preserving of the surface of the mercury in the burette by means of a layer of liquid such as oil or brine; and (4) the introduction of a liquid

Title: Improvements in or relating to electric pulse circuits
IPC: H04J3/04
Filed: 1947-11-28
Abstract: 638,683. Pulse generating circuits. GENERAL ELECTRIC CO., Ltd., and CRIGHTON, I. G. Nov. 28, 1947, No. 31548. [Class 40 (vi)] In a pulse generator an input pulse is applied between the control grid and cathode of a valve to cause a resonant circuit in the anode to "ring," the resonant circuit having a period which is less than twice the input pulse duration, a first point on the resonant circuit is connected to the anode, a second point to cathode and one output terminal and a third point to the other output terminal so that the potential of the first and third points with respect to the second vary in opposite phase and undesired oscillations at the output terminal are suppressed. Fig. 4 shows a pulse generator in which when positive going pulses are applied at the input terminals T1, T2, the resonant circuit L1, C1 rings and is slightly less than critically damped so that a damped wave train is generated, Fig. 2 (b) (not shown), but due to the suppressing action of rectifier G1 only a single positive going pulse which is narrower than the input pulse is applied to the grid of valve V2. The circuit L2, C2 which resonates at a higher frequency than circuit L1, C1 similarly rings and produces a positive going pulse at the output terminal T3 which is of still shorter duration. Valves V1 and V2 are normally biassed to beyond cut-off in the absence of an input pulse.

Abstract: 1,199,033. Making connectors; expanding by fluid pressure ; extruding ; punching. WESTERN ELECTRIC CO. Inc. 10 July, 1967 [12 July, 1966], No. 31617/67. Headings B3A, B3P, B3Q and B3W. A coaxial cable connector 10 is made from tubular stock 24 by extruding the forward end of the stock rearwards by a die 18 to bow the stock and expanding the bowed portion into a cavity 19 of a die 16 by fluid pressure. The stock is fed along a fixed mandrel 31 and clamped to the mandrel. The die 18 has a bore 34 of smaller diameter than the stock and a stop shoulder 38. The die is moved towards the mandrel and extrudes the material of the stock into the cavity 19. The mandrel 31 and the die 18 cooperate to shear a small piece 47 of the end of the stock. During the latter part of the advance of the die 18 silicone oil is fed under high pressure through the bore 37 of the die and the bores 32, 33 of the mandrel to expand the stock into the cavity. During expansion the stock is severed from the expanded part by a shoulder 21. After expansion a punch 40 is actuated to cut a hole 13 in the wall of the formed connector. The fluid pressure is maintained within the stock during punching. The punching process forms the subject-matter of Specification 1,199,034. Alternatively the hole may be punched by forcing the stock by fluid pressure against an opening in the cavity wall as described in Specification 1,166,532. The die 18 is then withdrawn and the formed connector removed. The stock may be long enough to form one connector only or be a length fed intermittently to the dies. The die 16 has a bore 26 which is normally plugged when ductile stock of copper or low carbon steel is used but the plug 27 is removed when hard stock of molybdenum or high carbon steel is used so that a differential hydraulic pressure can be applied to the stock. The stock is preferably of circular cross-section but may be rectangular and have a non-uniform thickness. In an alternative embodiment, Figs. 5 and 6 (not shown), the die 18 comprises a pair of relatively movable coaxial rams (61), (63). A set of friction blocks (64) are adjustably provided on the outer ram (61) to engage the inner ram (63). A feed mechanism (71) for the stock comprises a housing (72) with a pair of sets of segmented blocks (74), (76). The blocks (74) are held in the housing by light springs (77) and the blocks (76) held by strong springs (78). The housing is reciprocated by a piston (97) of a double-acting hydraulic cylinder. When the housing is retracted the blocks slide over the stock until the blocks (74) abut a spring-urged plunger (89). This moves the blocks (74) so that they grip the stock for the last part of the retraction to pull the stock end into a bore 23 to restore the stock end to its original size. On the forward stroke of the housing the blocks (76) grip the stock all the time. The apparatus may be operated in automatic sequence or by manual control.

Abstract: 1,076,924. Field effect transistor circuits; F.M. receivers; automatic frequency control. RADIO CORPORATION OF AMERICA. Aug. 5, 1964 [Aug. 23, 1963], No. 31880/64. Headings H3A, H3R and H3T. An insulated gate, field effect transistor has a variable voltage applied to a substrate electrode to vary the source input and drain output capacitances, and therefore the tuning of input and output circuits having inductors shunting the capacitances. Alternatively, an inductor may connect the drain and source electrodes of amplifiers having two such transistors in cascade, and resonate with the drain output and source input capacitances at the operating frequency variable tuning bias being then applied to both gate electrodes. In Fig. 7, the drain output circuit and gate circuit 150 are coupled so that oscillations are generated and the circuit is a converter, output circuit 142, 152 being tuned to the I.F. and inductor 148 resonating with the drain output capacitance 160 at the incoming frequency. Substrate voltage -V, reverse biasing the source and drain semi-conductor junction capacitance, may vary conjointly the tuning of the input circuit and local oscillator frequency so that the oscillator tracks the incoming frequency, although the input and output capacitances are unequally varied. Alternatively, a frequency discriminator may detect the I.F. and produce an AFC voltage added to -V to vary both the local oscillator frequency and the input circuit tuning. In Fig. 8, input is applied to the gate electrode of a neutralized amplifier, the gatedrain capacitance and the drain capacitance 180 in series forming one leg of a balanced bridge, with variable capacitor 188 and capacitor 190 forming the other leg. The neutralizing is unaffected by varying the tuning voltage -V 2  since the varies also the source-drain current and voltage across resistor 176 in series with the drain supply voltage V 1 , resulting in the gate-drain inherent capacitance becoming varied proportionately with the output capacitance 180. The circuits may form part of an FM receiver.
