Abstract: 558,175. Roads, runways &c. NEUCHATEL ASPHALTE CO., Ltd., and IONIDES, P. D. Sept. 15, 1942, No. 12997. [Class 1071 Layers of fluid material of high consistency, such as hot mastic, are laid upon surfaces, for example in forming coverings of roads or runways, by moving relatively to the surface a vessel containing the material in a hot fluid state, and extruding the material from the vessel on to the surface through an elongated orifice at a rate substantially proportional to the speed of movement of the vessel. A vehicle, comprising a chassis 2 on pneumatic tyre wheels 3, is adapted to be drawn by a tractor and has automatic braking means 4 to prevent over-running ; the vehicle carries four hydraulic rams 52 supporting through ball and socket connections a vessel 1, of thin steel plate, formed of upper and lower parts connected by flanges 113, the upper part having a reinforcing ring 10, and the lower part having an elongated aperture 5. A piston within the vessel 1 has a bevelled lower edge and asbestos packing rings and is connected to the plunger 29 of a hydraulic ram 8 pivoted at 17 in a frame 14 secured to the vessel ; the piston, after removal from the vessel, may be swung laterally by chains 22 secured to arms 21 and driven by a handle 25 through gearing 26, a pawl 28 and ratchet wheel 27 then holding the parts. A pump 9 is driven from one of the wheels 3 through a chain 33 and a clutch, and delivers fluid to the ram 9 to cause the piston to extrude material through the aperture 5 at a rate proportional to the speed of the vehicle; the pump 9 may also be driven by a handle 41, shaft 40, chain 42 and a clutch to apply initial pressure to the piston. A second pump 44 may also be driven by handle 41 and shaft 40 through chain gearing 45, a clutch and spur gearing 49, 51, and supplies fluid either to the ram 8 to raise the piston, or to the rams 52 to raise the vessel 1 and parts carried thereby for transport ; mechanical means may be provided to hold the vessel in raised position. The aperture 5 leads to a spout comprising a hinged leading side 59, which may be raised by a handle 62 or link 67 to close the aperture ; the trailing side of the spout comprises an oil-saturated wooden screed 69 backed by a metal plate 68 pivoted at 70 and provided with arms 74 to which weights are applied to load the screed. The operative position of the screed is determined by runners 71 pivoted thereto by pins 72 and connected to plates 75 which form the sides of the spout and have wedge-shaped lower edges. Behind the vehicle, a gritter may be trailed to deposit sand, stone chips or camouflage material such as wood chips. The mastic used preferably comprises 12- per cent bitumen, 18 per cent filler and 70 per cent aggregate at a temperature below 450‹ F. It may be applied in spaced strips, the spaces then being filled in after suitable runners have been applied to run on the initial strips; a lateral strip may be applied similarly. Specification 558,148 is referred to.

Title: Improvements in or relating to methods of coating a support with a lead sulphide layer
IPC: H01L21/00
Filed: 1956-04-30
Abstract: Supports, e.g. semi-conductor devices (see Group XXXVI), are coated with lead sulphide by deposition at above 50 DEG  C. from a solution of lead acetate and thiourea in the presence of hydrazine.  The reactants may be mixed and heated or hot solutions may be mixed: in the latter case the lead acetate solution is preferably added last. During deposition the solution may be stirred by bubbling through nitrogen containing a few per cent of hydrogen.  After deposition the support may be washed in water and if desired also in ammonium sulphide solution, dried and heated in air to 70-120 DEG  C. Supports referred to may be of glass, quartz, ceramic or plastic and may be provided with electrodes before or after deposition of the lead sulphide (e.g. by using a graphite suspension) or before deposition (by depositing noble metals from vapour, firing a silver or silver oxide suspension to the support or spraying tin chloride on to the support heated e.g. to 500 DEG  C. to give conductive tin oxide).  It is stated that it is known to use alkali metal hydroxides in place of the hydrazine.

Filed: 1925-05-21
Abstract: 234,497. International General Electric Co., Inc., (Assignees of Allgemeine Elektricitõts Ges.). May 21, 1924, [Convention date]. Drawings to Specification. Compound and multiple-expansion engines.- for the economical pre-heating of feed-water in steam-engines, more particularly in steam turbines, the steam after it has been superheated and worked in one part of the engine, is cooled, before its further expansion in the remaining part of the engine, by passing it through a heat-exchanger for heating the feed-water. The intermediate cooling of the working steam, which may occur after it has been superheated and expanded several times, begins at a temperature corresponding to the boiler live steam temperature, and ends on saturation temperature being reached. The feed-water may first be pre-heated by steam tapped from the lower stages of the turbine. The heat-exchange apparatus for the intermediate superheating and cooling may be inserted in the connecting pipes between the individual turbine casings. The temperature of the exhaust steam may be maintained by repeated inter-change reheating at boiler live steam temperature, and its latent heat may be abstracted in a feed-water pre-heater.

Title: Improvements in retractable undercarriages for aircraft
IPC: B64C25/20
Filed: 1941-10-16
Abstract: 567,749. Aircraft undercarriages. FLURSCHEIM, C. H., and METROPOLITANVICKERS ELECTRICAL CO., Ltd. Oct. 16, 1941, No: 13352. [Class 4] A retractable undercarriage for aircraft comprising a resilient telescopic leg carrying the landing element and pivoted to the aircraft, is braced in its extended position by pair of collapsable toggle links, a latch for locking the toggle links in their straightened position being connected to a chain or cable passing over a reversible winch so that when tension is applied to the chain or cable the latch is released and the toggle links folded to retract the undercarriage. In one form, an oleo-pneumatic shock-absorbing leg 7 pivoted to the aircraft at 2 is braced in its operative position by toggle links 4, 5 locked in their extended position by a latch 15. A link 12 pivoted to the sliding part 8 of the leg 7 has a slot 13 engaging a pin 14 on the link 4. The slot rides over the pin under taxying loads, but when the aircraft is airborne, the pin 14 engages the top end of the slot. The undercarriage is raised by pulling on a cable or chain 20 which first releases the latch 15 and then raises the pivot 6 of the links 4, 5. From the extended position to the position shown in dotted lines, the link 12 progressively forces in the part 8 of the leg against resilient resistance, after which the stored energy assists the further retraction movement by helping the movement of the link 4. The catch 15, Fig. 1A, has projections 17 engaging a roller 18 carried by an extension of the link 5. Fig. 3 shows a . modification in which a lever 24b pivoted to the strut 7 is connected by a slotted link 24 to the sliding part 8, the end of the lever 24b engaging a roller 4b carried by the link 4. As an alternative to the latch 15, Fig. 4 shows a bell-crank lever 38 pivoted to the part 35 corresponding to the link 5, the lever having a roller 49 engaging an abutment 41 on the part 34 corresponding to the link 4. A spring 42 urges the lever into its locked position from which it is released by the pull of the chain 20 at the beginning of the retracting movement. In another form, a plate 47, Fig. 5, is pivoted about the joint pin of the toggle links, the plate being connected by a link 49 to a pivoted catch 51 for engaging a roller 56 corresponding to the roller 18 of Fig. 1. A spring 54 urges the parts to the position shown and the lever 51 is moved to unlock the joint by the pull of the chain 57. A chain, as described in Specification 567,750, may be used for retracting and extending the undercarriage.

Abstract: 825,403. Fluid-pressure servomotor-control systems. EKSTROMS MASKINAFFAR A.B., A. April 29, 1957 [April 27, 1956], No. 13641/57. Class 135. A regulator for maintaining a constant pressure or pressure difference and suitable for controlling the air or gas supply to combustion apparatus comprises a diaphragm 306 clamped between upper and lower casing members 302, 301 and sandwiched between upper and lower plates 305, 303 of which the latter is pivotally mounted on a shaft 304, a link 325 connecting the diaphragm to a control valve 323, and a restoring device consisting of pistons 311, 312, subject to the output pressure from the control valve and acting through a diaphragm 308 on the diaphragm 306 in a restoring sense. The arrangement shown is suitable for controlling a pressure supplied to the lower side of the diaphragm 306 through a conduit 331, this pressure being balanced by an adjustable spring 326 Any deviation of the control valve 323 from its neutral position shown causes pressure fluid to be supplied from a conduit 321 to a conduit 329 or to be exhausted from the latter depending upon the direction of movement of the valve. The pressure in the conduit 329 is fed through a conduit 330 to a servomotor (not shown) operating a draught valve or varying the speed of a flue gas fan. Variation of the pressure in the conduit 329 also causes movement of the pistons 311, 312 whereby the pressure above the diaphragm 308 is varied in a sense to oppose the deflection of the diaphragm 306. A bleed 318 below the piston 311 enables the pressure below the piston 311 gradually to be restored. A bleed 319 above the piston 311 discharges leakage past the piston 312. The diaphragm 306 may be replaced by a bellows as also may be the pistons 311, 312. In a modification, for controlling the pressure difference across an orifice plate, the two pressures are connected to opposite sides of the diaphragm 306 and the valve 323 is actuated from a point opposite the diaphragm 308, the connecting-link for the valve passing through a diaphragm in the lower part 301 of the housing.
