Abstract: 395,573. Regulating-switches. LEA, J. E., Recorder House, Cornbrook Park Road, Old Trafford, Manchester. Nov. 29,- 1932, No. 33745. [Class 38 (v).] In a system for indicating or recording the variations of a measured quantity of the type wherein a member moved in accordance with the quantity adjusts a resistance in the indicating circuit, a cam mechanism is interposed between the member and' the adjustable contact of the resistance in order to produce proportionality between the indications and measured quantities. As shown in the Figure wherein the apparatus is adapted for indicating the flow of liquid, a chain n<1> operated by a float, rotates a spindle carrying a drum m having a cam groove m<1>, with' which co-operates a spring arm o maintained in association with the groove by a rod p. The arm o is carried on a slide j<1> movable in rollers j<2> and carrying a rack j meshing with a pinion i on the spindle f of the rotatable contact arm e of an annular resistance c. The resistance is connected to contacts clover which the arm e moves. Upon rotation of the drum m, the slide j is moved longitudinally to impart rotary motion to the contact arm e, by the cam groove m<1> and spring arm o. The cam groove is shaped so that the indications produced by the variations of resistance are proportional to the variations of the quantity being measured.

Abstract: 772,008. Electromagnetic relays. ERICSSON TELEPHONES, Ltd., and DISTIN, L. S. Dec. 3, 1954 [Dec. 5,1953], No. 33881/53. Class 38(5) Cantilever contact blades 21 on an insulating member 18 pivoted at X engage fixed contacts 23 when the member 18 is oscillated electromagnetically as in the polarized relay disclosed in Specification 695,664. To ensure adequate contact pressure between each contact pair in the event of uneven wear amongst the pairs, each blade 21, after it has engaged its fixed contact 23, is engaged by a projection 35 on the member 18, whereby further movement of the member 18 causes the blade to flex about the projection instead of about its root end. The projections may be integral with the member 18 or may be separate parts adjustably mounted on the member. Plates 36 spaced from the blades 21 prevent undesired blade vibration.

Title: Moisture-extraction devices

Filed: 1974-08-02
Abstract: 1462295 Drying air; plate-type evaporators and condensers LINDE AG 2 Aug 1974 [7 Aug 1973] 34120/74 Headings F4V F4H and F4S [Also in Divisions B1-B2] An air drying device comprises an evaporator and a condenser in a closed refrigerant circuit and a fan for causing moist air to flow successively in heat exchange contact with the evaporator and condenser, wherein the evaporator is a plate-type heat exchanger. The evaporator comprises identical corrugated sheet metal panels 12 to 15 arranged in pairs with alternate pairs inverted relative to the remaining pairs so that the corrugations of adjacent pairs are offset. The contacting corrugations of each pair define parallel flow passages 18 for the moist air. Beads 19 are pressed in each panel and extend transversely to the corrugations. The beads 19 of facing panels 13, 14 of adjacent pairs of panels contact one another to separate the offset corrugations of panels 13, 14 to define sinusoidal flow passages 25 for the refrigerant. The beads 19 of the panels 12, 13 or 14, 15 contact one another to define passages linking the flow passages 18, whereby water separated from the air flow may drain from the evaporator, which may be located with the passages 18 inclined to the horizontal. Aluminium foil, 20 e.g. 0À2 mm. thick, is trapped between the corrugations of panels 12, 13 or 14, 15 to form extended heat transfer surfaces. Projections 21 from the foil define V-shaped baffles located in the passages formed by the beads 19 to catch water droplets in the passages 18 and to cause air turbulence. The corrugations are less deep between than at the beads 19, as at 24, so that each flow passage 18 narrows between adjacent baffles 21. The panels are seam welded at edges 27. The condenser may have the same construction as the evaporator.

Filed: 1927-12-17
Abstract: 282,442. Siemens & Halske Akt.- Ges. Dec. 18, 1926, [Convention date]. Regulation, automatic.-An automatic electrical relay device for regulating steam boilers, e.g. the travelling grate, the flue dampers, the feed water valves or the like, in response to temperature variations, is illustrated in its application to the regulation of a flue damper attached to the lever 19, controlling the superheat of steam drawn of through a pipe 2. A thermocouple 3 operates a temperature indicator 4, the pointer 12 of which moves close to a resistance 11. The pointer 12 and relay 16 form the bridge connection of a Wheatstone bridge, the two arms of which are constituted by the resistances 10, 11. A member 13 is pressed down on the pointer 12 at regular intervals, but if the steam is at the desired temperature there is no current through the relay 16. If the pointer 12 is deflected, it will be pressed on to the resistance 11 at a point which will unbalance the bridge, the relay 16 will be energized, and the motor 8 rotated to move the slider 6 and arm 19. The pointer 6 is moved over the resistance 10 till the bridge is again balanced and the motor is no longer rotated.

Abstract: 357,846. Petrol gas. HARROLD, W. G., 1, Glamorgan Street, London. Nov. 14, 1930, No. 34295. [Class 55 (ii).] In carburetting apparatus for making air gas of the kind in which a liquid hydrocarbon such as petrol is spread on the outer surface of a rotating metering device, the latter is caused to rotate by the passage of air which is subsequently carburetted. A casing 11 contains a drum 12 divided into chambers, and mounted on a shaft 13 having a sprocket wheel 14 which drives another sprocket 18 on a stub shaft to which is fixed a petrol feed wheel 17 supplying measured quantities of petrol from a container 15 into the flared end 16a of a pipe 16 leading to the casing 11. An electrically driven fan 19 of the open type supplies air through a condensation trap 20 to a pipe 21 in the receiving chamber of the metering drum, while an outlet pipe 22 serves to withdraw the gas from the carburetting chamber. When the fan is started, and the drum revolved, petrol flows down the feed pipe 16 to the outer surface of the drum 12 over which it spreads in the path of the incoming air. The evaporating surface is proportioned to the amount of petrol supplied, and to the air supply, owing to the controlled movement of the drum, the ratio of air flow and area of petrol-spread being constant.

Further, part of the gases escapes through ports e<1> and the remainder passes still rearwardly into an expansion tube k round the barrel. According to the present invention, the gases expand still further into a second tube l, Fig. 3, round the barrel from which they return forwardly through an annular gap k<2> between the tubes and strike against the gases already discharged through the rear ports k<1> of the deflector system. The helicoidal motion of the gases initiated by the rifling is continued by helical ribs bl, i, h. The transverse section of the gas passage f is arranged to be substantially constant and the ports el, k<1>. are inclined in the direction of the resultant motion of the gases. A cooling medium is injected into the gases by means of a pipe n<2> leading to a cavity n, the outlet from which is in the form of narrow slits n<3>. Specification 389,469 also is referred to.

A pneumatic remote control system for a plurality of engines comprises a reservoir 2 for each engine, the pressure in which, and hence the position of the engine control means operated by a fluid pressure motor 7, is controlled by an electromagnetically operated inlet valve 4 in the pipe 3 connecting the reservoir to a compressed air supply 1, and at least one electromagnetically operated outlet valve 5, 6, controlling escape of air from the reservoir 2, the valves being controlled remotely by switches 8, 9, 10. Orifices 15, 16, in the inlet and outlet pipes control the rate of rise and fall of pressure in the reservoir 2. Opening of the valve 4 causes a rise in pressure in reservoir 2 and hence an increase in speed and opening of the valve 4 a slow drop in pressure and decrease of speed. Opening of the valve 6 causes a rapid drop in pressure and decreases engine speed quickly. The circuits of the valves 4-6 of all the engines are interconnected by lines 17-19 for simultaneous operation. The orifice 15, in a supercharged engine, is dimensioned to keep the increase in speed in line with the increase in the blower output during acceleration.
