An air heater comprises a heat-exchanger 10, an adjacent heating chamber 9 which is larger in over-all crosssection than the heatexchanger, and an outer shell comprising two parts, an upper part 1 which fits closely around the upper part of the heat-exchanger 10 and a lower part 2 which has a larger cross-section than the part 1 and surrounds and is spaced from the chamber 9 and the lower part of the heatexchanger. In the form shown, the chamber 9 is a combustion chamber with an oil burner 15, and the heat-exchanger comprises four tubes of elongated cross-section. The combustion gases flow through the tubes to the outlet 14, and the air to be heated is forced by a fan 5 through the space between the chamber 9 and shell part 2 and through the spaces between the tubes to outlets 8. The tubes have internal and external fins 24. Near the ends of the tubes the external fins are oriented as shown to guide the air flow. The lower ends of the tubes may have refractory linings. In another form, four flanged finned parallel plates are assembled with their flanges in contact within a casing of rectangular crosssection to form two vertical hot-gas passages alternating with three air passages. The heating chamber and lower shell part are cylindrical and the air may be supplied tangentially to the space between them. Specification 744,963 is referred to.

Title: Improvements relating to railway track brakes operated by the weight of a vehicle
IPC: B61K7/12
Filed: 1934-11-02
Abstract: 447,048. Reciprocating pumps. VEREINIGTE EISENBAHN - SIGNALWERKE GES., Siemensstadt, Berlin. Nov. 2, 1934, No. 31547. Convention date, Aug. 24. [Class 102 (i)] [See also Group XXXIV] Track brakes on permanent way operated by the weight of the vehicle are lifted into operative position by water pressure derived from a two stage pump, the low pressure stage is put out of action by a known suction valve releasing device operated by the brake operating fluid and the high pressure stage is put out of action by a pressure regulator when the brake pressure selected in reached. To operate the brake the brake hand lever 1 of the regulating valve is moved to the right to allow valves a, b to close whereupon, pumps N, H pump water into a pipe 5 leading to the brake apparatus and when the pressure in the pipe attains a certain value it acts on a piston 8 connected to the suction valve 10 of the low pressure pump N raising this valve and putting the pump out of operation. The pump H increases the pressure in the pipe 5 until a piston 12 is moved against a spring 14 and re-opens the valve b which allows pressure-fluid to pass from the pipe 5 by a pipe 16 to raise a piston 17 connected to the suction valve 18 of the pump H which is thereupon put out of action. To increase the pressure in the pipe 5 the lever 1 is moved further to the right to close the valve band open a valve c to release pressure from piston 17 and the pump H operates again until the pressure in the pipe 5 is sufficient to again move the piston 12. To reduce pressure the hand lever is retracted to open the valve a and the pressure fluid escapes until the valve a recloses by movement of the piston 12. In a modification the high pressure stage has no suction valve releasing means and is switched off by the regulator which byepasses its discharge back to the reserve liquid tank when the pressure in the brake pipe has attained a value corresponding to the position of the hand lever.

Title: Honeycomb materials
Inventor: WHITE DESMOND DEVERELL
IPC: B31D3/02
Filed: 1961-09-06
Abstract: 985,823. Laminates and laminating. DUFAYLITE DEVELOPMENTS Ltd. Aug. 31, 1962 [Sept. 6, 1961], No. 32042/61. Heading B5N. In apparatus for expanding slices of non- metallic honeycomb, e.g. paper, cardboard or thermoset resin-impregnated paper to yield a stabilized material, which may be used as such as a packing material, slices of preformed honeycomb are bonded together by stripes of adhesive while being pressed forward by a reciprocated bar 4, Fig. 1, in front of which the slices are placed manually, towards a sponge rubber roller gripping device 109, which tends to resist further advancement. A second gripping device in the form of an endless conveyer having transverse rods 132 provided with pins 133 for engaging the honeycomb is driven much faster than the roller 109 so that the material is expanded between the two gripping devices. During expansion the honeycomb is supported on a slightly upwardly inclined track of parallel wires to facilitate disengagement of the pins 133. The honeycomb is then fed through a heated chamber to stabilize or consolidate the sheet, e.g. in a curing chamber for thermosetting resin-impregnated paper or a drying chamber for paper or cardboard containing moisture. To strengthen the material further, or for other uses than packing, a web of flexible material, e.g. paper, may be laminated to one or both sides of the material, by apparatus comprising upper and lower endless canvas belts 422a, 422b, Fig. 3, passing between heatable metal pressing plates 401, 402, the faces of the honeycomb core being coated with adhesive, e.g. china clayloaded sodium silicate, by a roller 416b supplied from a bath 410 and by a pair of rollers 416a, 417a, between which a pool of adhesive is maintained at constant level from a supply pump. The core material may alternatively be faced with hardboard, plywood or material impregnated with melamines or other resin. To permit ventilation of the core material during hot processing notches may be cut in the unexpanded slices by circular saws in slots in the table 2, Fig. 1.

Title: An improved electromagnet relay chiefly designed for recording electric surges
IPC: H02H3/04
Filed: 1945-11-30
Abstract: 619,765. Electric tests. LANDIS & GYR SOC. ANON. Nov. 30, 1945, No. 32463. Convention date, Nov. 30, 1944. [Class 37] An electromagnetic relay responsive, selectively, in one of two ways to current impulses of varying magnitude and duration, comprises a three-limbed iron core, Fig. 4, having an armature 12 pivoted at 10a on the central limb 10 and biassed by a tension spring 15 against a stop 16 adjustable to vary the air-gap L1. The core leg 9 and corresponding armature limb are made of smaller sectional area than the adjustable core leg 11 and armature limb corresponding thereto, so that, of the two parallel magnetic circuits energized by the relay coil 13, that through leg 9 saturates at a lower flux value than that through leg 11. In operation, when the coil 13 is energized, nearly all of the magnetic flux generated thereby flows through leg 9 until saturation, after which the flux builds up in the leg 11. With a large surge current the flux build-up is so rapid that the impulse, i.e. the time integral of the attractive force, acting to rock the armature 12 against the action of spring 15 is insufficient to rock the armature because of the rapid build-up of the opposing impulse produced by the flux through core limb 11. During flow of the follow current, however, the opposing impulse is insufficient to prevent rocking of the armature which actuates the follow current counter 3 mechanically through a pallet 18. As shown in Fig. 1, a surge voltage in a line 8 breaks down the diverting conductor 7 and a surge current passes to earth through the resistor 4, the resistance of which is voltage dependent. In parallel with resistor 4 are a resistor 5 which actuates a surge counter 6, and a follow current relay 1, as above described, which responds only to the " follow " current subsequent to the surge, i.e. the current produced through the resistor 7 by the normal line voltage, and which persists for a maximum of one half a cycle of the line frequency. The impedance of the relay is such that it carries substantially all of the follow current.

Title: Salicylates
Inventor: SPIVEY ARTHUR MARSHALL
IPC: C07C69/88
Filed: 1956-10-25
Abstract: The invention comprises ascorbyl trisalicylate, salts of ascorbyl trisalicylate in which the acid hydroxyl group of the ascorbyl residue has been neutralized with a base and a process for the production of ascorbyl trisalicylate or a derivative having substituted phenolic groups, in which a salicylyl halide or its appropriate substitution derivative is reacted with ascorbic acid in the presence of an hydrogen halide acceptor.  The reaction may be effected by mixing salicylyl chloride or a derivative thereof with ascorbic acid and pyridine.  Derivatives may be obtained in which the phenolic group are etherified, e.g. with methyl, ethyl or propyl groups or acylated, e.g. with acetyl or propionyl groups.  Thus ascorbyl tri(acetyl salicylate) may be obtained.  An example describes the preparation of ascorbyl trisalicylate and its monosodium salt.
