Abstract: 510,792. Signalling over power circuits. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd., and ROSEBY, P. N. Feb. 7, 1938, No. 3782. [Class 40 (iv)] In a system in which signals are transmitted over a low-tension power network via a hightension network, signals at the receiving end of the H.T. network are lowered in frequency by heterodyning with a locally produced oscillation or with one sent out with the signal. As shown, signals at 2000 and 2800 cycles are applied by apparatus HFG to an L.T. network and are conveyed via an H.T. network 10... 12 to a transformer station B where the two components are filtered out and applied to separate grids of a mixing valve V. The beat frequency is amplified at 13 and applied to an L.T. network 1 ... 3, N. The amplifier 13 may be normally inactive, its cathode heating circuit being closed by a relay in the anode circuit of the mixing valve when a signal is received. Specification. 502,407 is referred to in the Provisional Specification.

Abstract: 1,153,694. Magnetic switches. ITT INDUSTRIES Inc. 25 Jan., 1968 [20 Feb., 19671, No. 3896/68. Heading H1N. A thermally responsive switch has blade contacts, one of which carries magnetic material influenced by two permanent magnets and one at least of the magnets is moved by a temperature-responsive member. The latter is shown in Fig. 1 as a bimetal spiral 11 having a permanent magnet 12 at its end adjacent a sealed contact unit 13 which has three contact blades 16, 17, 21 of which the blade 21 is provided with a magnetic armature body 23. A second permanent magnet 14 normally attracts the body 23 to hold contact points 19, 22 closed until the bimetal 11 moves the magnet 12 across a dash line shown in Fig. 1 so that the magnet 12 is snaped against the glass contact envelope 20 and contact points 19, 22 are opened at the same time as contact points 18, 22 are closed. The body 23 may extend along the blade 21 a greater distance on the side adjacent the first magnet 12 so as to permit a greater degree of bending in the other direction and ensure adequate contact pressure in the position shown. The lower ends of the contact blades (Fig. 4) are clamped together, with interleaved insulators 30, 31, by the bent over edges of the blade 17 and are located on an insulatng plug 33. The magnet 12 may have oppositely poled layers as shown in Fig. 5 and the bimetal layer 36 may be of ferromagnetic material. The second magnet may be movable with the first by means of an extension of the bimetal (Figs. 6 and 7, not shown).

In a nuclear reactor, reactivity control is effected by neutron spectral shift produced by changing the proportions of H 2 O and D 2 O in the liquid coolant-moderator. Liquid is injected by gas pressure into the coolant circuit to produce the required change, from a storage tank and a second tank receives the displaced liquid. The gas pressure also serves to pressurize the liquid moderator. The injection and displacement is effected by adjustment of valves associated with the moderator liquid pipe circuit. The temperature of the injected liquid may be adjusted to that of the coolant prior to injection. Rapid shut-down is effected by the injection of a soluble poison into the coolant-moderator circuit.

Single-acting piston pumps; regulating delivery by opening suction valves; valves, arrangement of; valve-gear.-A fuel pump comprises a plunger 5 working in a barrel 6 which is reciprocated by a cam 13, rod 18, and lever 19, so that its end serves as an inlet valve. The cam is shaped to keep the barrel in the open position for a portion of the delivery stroke, the period of opening being adjusted by sliding the cam along the shaft 8. The barrel is carried by a diaphragm 23 mounted in a hole in a partition 28 in the casing 1, and is returned to its seat 10 by a spring 22. The downward movement of the diaphragm draws the fuel into the suction chamber 4. When the barrel is closed on its seat 10, the plunger delivers the fuel through the valve 12. In another form, adjustment of the period of opening of the barrel is effected by moving the arm 18 laterally over the curved surface of the cam. In another form, the spring 22 moves the barrel downwards, and the cam and lever mechanism close it. Several pumps may be operated by the same shaft, the cams 13 being mounted on a separate axially-adjustable shaft.

Abstract: 625,163. Filters. ALLAM, P. S. (Fram Corporation). Feb. 13, 1947, No. 4186. [Class 46]. A filter element comprises a continuous sheet of paper or other filtering material having substantial rigidity, of generally tubular form, and axially collapsed to provide contaminant - collecting walls diverging from transversely - extending fold-lines. As shown in Fig. 6, a sheet of paper or the like 11 is scored along lines 12 to 15 and then made up into tubular form, Fig. 7. When pressure is brought to bear on the ends of the element and on the longer horizontal lines 15, the element assumes the concertina-like configuration of Fig. 8, in which the score lines 14 have all become outward folds 21 in planes transverse to the axis, and the score lines 15 have become outward folds 24. Further pressure on the ends of the element results in the configuration, as shown in Fig. 2. A perforated tube 31, Fig. 1, is then inserted in the element, and circular end plates 33 affixed. The element is then threaded over a central tube 41, in a casing 36, and rests on a washer 45 and flange 46. A further washer 44 is threaded on the tube 41 and a spring. 43 interposed between the cap 38 and casing 36. The element 20 may be encased in an outer perforated metal cylindrical tube, the edges of which are connected to those of the end plates 33 before being inserted in the casing. The latter outer perforated tube may have a hexagonal cross-section corresponding in shape with the element, and the end plates may be shaped accordingly. The element may be formed from a cylinder of unscored sheet material, the concertina-like configuration being brought about by pressure at the ends and at appropriate places along the sides.

Selector valves 10, 11 on the discharge side of each pump are operated by levers 15 and coupled through a lever 17 to a servo system providing maximum pump output whenever a selector valve is in maximum stroke position. The lever 17 controls the pump swash plate 22 through a valve 44, Fig. 5, and a piston 34 which follows the movement of the lever until a link 42 has rotated a feedback sleeve 45 sufficiently to interrupt the flow through the valve. The link 42 also adjusts the position of a sleeve 43 to vary the value at which pump output pressure is regulated by a spring-loaded valve 50 in series with the valve 44. The valve 50 ensures that the sum of the pump outputs is less than the output of the prime mover. A trochoid pump 32 supplies the servo system.

Abstract: 126,931. Muir & Co., W., Melloy, J. H., and Owen, W. Feb. 20, 1919. Gear-cutting.-In a machine for cutting spur and spiral gears by a reciprocating generating cutter, the indexing motion is performed instantly by dropping the work back at the end of the rolling motion a pitch or more than one pitch during the interval between the cutter leaving the work and re-entering it, in order to avoid any pause in the cutting. The rack-cutter E is carried by a vertically reciprocating slide A. and the work is carried by a table J, which is rotated on a cross-slide H<1>, mounted on an adjustable slide H. The cross-slide H<1> is traversed during cutting by a scroll cam Q on a shaft P acting against a similar fixed cam Q<1> on the slide H<1>, the pitch of the cam Q being equal to or a multiple of the pitch of the gear being operated on. On completion of a revolution of the shaft P, the cross-slide H' is pressed back by spirngs S or other means a distance equal to the pitch of the cam and cutting automatically recommences. The table J is rotated by worm and spur gear from the shaft P, which is rotated by gear L' from the shaft L.
