IPC: B64C25/46
Filed: 1957-01-23
Abstract: 871,243. Fluid pressure brakes. DUNLOP RUBBER CO. Ltd. Jan. 10, 1958 [Jan. 23, 1957], No. 2367/57. Class 103 (1). An aircraft braking system comprises an automatic control apparatus 18, 19 associated with each fluid pressure operated brake 3, 4 associated with landing wheels 1, 2 respectively, and electrical means associated with each brake to obstruct or restore the fluid supply from source 6 to one said brake in response to, and in synchronism with, the obstruction and restoration of fluid supply to the other said brake on operation of the automatic control apparatus. Rotary inertia mechanisms 18, 19 controlling valve mechanisms 16, 17 interposed in each pipe 7, 8 from pilot control valve 5 operates a cam 22 on skidding, to move rod 23 and pivot lever 24, Fig. 2, to close inlet valve 25 and open exhaust valve 26 to release fluid from the brake 3 or 4 to reservoir 15 via pipes 46 or 47 and 45. On speeding up of wheel 1 or 2, valve 25 is reopened and valve 26 closed to reapply the brakes 3 or 4. The brakes are applied for a certain time after retraction of the wheels and are prevented from application on landing until the wheels reach a certain rotating rate by a valve 27, centrifugal latches 28 and valves 30, 31 as described in Specification 732,609. On skidding of one wheel 1 or 2, the rod 23 also moves a plunger 32 to close a microswitch 34 or 35 and energize a two-way solenoid-operated valve 39 or 38 in the pipes 8 or 7 respectively, to connect pipes 7a or 8b to pipe 45 and reservoir 15 to release pressure from the brakes 3 or 4 of the other wheel 1 or 2, hence ensuring that the aircraft will not deviate to one side. When the wheel 1 or 2 again rotates normally the switch 34 or 35 is opened to de-energize valve 39 or 38 whose shuttle 56 or 49 is operated by a spring to connect pipes 8a and 8b, or 7a and 7b to restore pressure simultaneously in each brake. The pilot valve 5 may be operated by an electric actuator 10 in pilotless aircraft. Specifications 676,708, 683,490, 704,168, 706,351, 733,834 and 737,148 also are referred to.

Title: Improvements in or relating to the manufacture of hollow articles from thermoplastic materials
Inventor: JACKSON JOHN MAXWELL
IPC: B29C49/42
Filed: 1960-01-25
Abstract: 901,819. Blow-moulding hollow articles. METAL BOX CO. Ltd. Dec. 6, 1960 [Jan, 25, 1960], No. 2721/60. Class 87(2). In a method of making hollow articles e.g. bottles, from thermoplastic material e.g. polyethylene, cellulose esters, polyvinyl chloride, or polystyrene, wherein a tube of the softened material is extruded continuously vertically downwards so that the leading end portion is enclosed by a sectional mould, 7, 8, the mould being reciprocable along the axis of extrusion to and from a datum position shown in Fig. 1, the length of tube enclosed in the mould is severed by a knife 3 while the mould is closed in the position shown by dotted lines in Fig. 1, and while the mould is returning to the datum position a blowing nozzle 9 is introduced into the top end of the enclosed tube, to effect an airtight seal to blow the tube into conformation with the inside of the mould by fluid pressure, The mould parts 7, 8 are mounted on a support 4, which is reciprocable in the frame 6 on bars 5. The blowing nozzle is mounted on a carrier 11, in turn mounted on a rocking arm 14, and as the closed mould descends with the enclosed tube, the rocking arm 14 is moved about the axis 15 to the position shown in Fig. 3, by an air cylinder 18. The carrier 11 is moved about an axis 16 by an air cylinder 17 so that the shoulder 10 of the blowing nozzle 9 forms an airtight seal with the top of the tube to give a flash 12. After blowing with compressed air the mould 7, 8 is opened, the nozzle 9 is returned to the position shown in Fig. 1, and fingers 21 fixed to the support 4 ensure that the bottle does not stick to either of the mould parts. An alternative arrangement for operation of the nozzle 9 is shown in Fig. 7 where the carrier 11 is fitted with rollers 24, 25 which engage in cam tracks 26, 27. Operation of the air cylinder 17a then causes movement of the nozzle between the position shown in Fig. 7 and a position where it is raised clear of the moulds and retracted out of line with the extruder. The nozzle 9 is retained in position in this case while the mould is opened and then a blast of air is used to eject the moulded article. In a further arrangement, Fig. 10, the carrier 11 is pivoted at 16a to a lever 30 slidable in a guide 31 and fitted with a roller 33 which engages with a track 34 in a fixed cam 29 to move the nozzle between the position shown in Fig. 10 and its blowing position. The nozzle is raised clear of the mould 7, 8 by engagement of a tail 35 on the carrier 11 with a cam 36. To ensure removal of the article from the mould, the nozzle is also moved, while held in the blowing position, in a direction at right angles to the plane of Fig. 10 by a cam mounted on the mould part 7, the movement taking place against a spring as the mould is opened, Figs. 13, 14 (not shown).

Title: Automatic compression control for internal combustion engines
IPC: F01L13/08
Filed: 1940-02-13
Abstract: 536,746. Starting stopping. WATSON, R. D., and YATES, G. Feb. 13, 1940, No. 2773. Convention date, Feb. 15, 1939. [Class 7 (v)] [Also in Group XXVI] An arrangement for controlling compression comprises means tending to interpose in a valve-actuating mechanism, a device for preventing closing of a valve actuated thereby, and fluid-pressure means controllable by the normal engine operation for maintaining the device in non-interposed position. In one form Fig. 1, exhaust valves 11 are actuated through rockers 22 and push-rods 20 from cams 16 on an engine-driven shaft 15 journalled in bearings 24, 25 supplied with lubricant by pump 26. Closing of the valve 11 at starting is prevented by a lever 35 interposed between the valve tappet 18 and a supplementary cam 37 on the shaft 15. The lever 35 oscillates on a shaft 40 slidable in cylinders 42, 51 and initially held in the position shown by a spring 50 abutting against an adjustable cap 52. When the engine is running normally, the lever 35 is moved out of interposed position by the pressure of lubricant admitted through a pipe 43 to the cylinder 42. The pipe 43 leads also to a relief valve 63 controlled from a thermal device 70 in the cooling jacket 71 of the cylinder head, so that overheating of the cooling water causes the valve 63 to be opened, allowing the spring 50 to interpose the compression-relief lever 35 and thus to stop the engine. The bulb 70 of the thermal device is connected to an expansible bellows 74 in a housing 75, the bellows being connected through a rod 76 and lever 82 to the stem 64 of the valve 63. A pin-and-slot connection between the rod 76 and lever 82 allows lost motion. The valve stem 64 may also be actuated manually, to stop the engine at will. In modifications, the cylinders 42, 51 for actuating the shaft carrying the lever 35 are mounted directly on the bearings 24, 25, and the stem of the relief valve is provided with a handle for manual actuation. In an arrangement for a multi-cylinder engine, Fig. 5, the cam shaft 113 is provided with cams for each cylinder, and a compression-relief lever 126 for each cylinder is carried by a shaft 127 slidable in guides 128 129 and actuated by a yoke 141 on a common rod 140 having a piston 139 actuated by the pressure of lubricant admitted to a cylinder 135. A relief valve 111 is provided for stopping.

Delivery of articles stored in piles.-Cylindrical containers 6 stored in a pile are supported by the arms of a member 9 having a step-by-step rotation to deliver the containers one at a time to a tray 21. Coin action, weight and multiple-coin. - The member 9 has a toothed disc 12 engaged by a spring-controlled trip lever 13 having an arm 13a positioned under a coin shoot 14 so that a coin in passing down the shoot 14 trips the lever 13 to permit one article to be delivered. In apparatus in which two coins are required a pivoted member 17, Fig. 2, diverts the first coin into a shoot 15 leading directly to a coin box, and diverts the second coin into the shoot 14. A bell-crank lever operated by opening or closing the door of the machine sets the member 17 each time the machine is re-stocked. Returning coins.-To enable inserted coins to be returned if the machine is empty a portion 18 of the shoot 14 is pivoted and has arms 18<a>, 18b, the latter bearing on the cylinders 6. If the machine is empty the arm 18<b> is unsupported and the portion 18 swings so that the arm 18<a> obstructs the shoot 15 and the outlet from the part 18 overlaps a shoot 19 leading to a returned coins receptacle. Fraud, preventing.-A weighted flap 22a closes the bottom of the magazine 7 for the cylinders 6 to prevent irregular access to the latter.

Title: Method of electrodepositing copper, and baths and compositions therefor
IPC: C25D3/38
Filed: 1945-02-07
Abstract: 597,407. Electrodeposition of copper. STARECK, J. E., and UNITED CHROMIUM, Inc. Feb. 7, 1945, No. 3109. [Class 41] A copper plating bath of pyrophosphate content is modified by the addition of 5-20 grams/litre of nitrate (NO3) radicals. The pH value of the bath for tank plating is 6.5 to 7.5 with optimum at about 7.2. Electrolytic or rolled copper anodes are used. Organic hydroxy acids which are capable of forming alkali-metal and heavy metal complexes in amounts equivalent to 5-25 parts citrate, e.g. citric, lactic, tartaric, glycollic and maleic acids or soluble salts thereof, may be added to the bath. An intimate admixture of the ingredients for making up a bath by dissolving in water comprises amounts by weight of the respective substances to give 7.5-45 parts bivalent copper, 100-250 parts pyrophosphate (P2O7) and 5.20 parts nitrate radical (NO3). Soluble salts of the organic hydroxy acids or the acids themselves referred to above equivalent to 5-25 parts of citrate may also be added. For replenishing the bath a similar admixture may be used but omitting the bivalent copper compound. The composition may be such as to give rise to the formation of the complex radical Cu(P2O7)2<SP>6e> as described in Specification 509,650. When depositing the copper on iron or steel or other less noble metals, the bath preferably contains pyrophosphate in excess of that represented by the above formula. Compositions of baths for tank and barrel platings are given and also for obtaining " strike " deposits where it is difficult to start the electrodeposition of the metal from the plating solution, the " strike " deposition being effected by raising the voltage and plating for a few seconds at a higher current density than is employed for regular deposition of the metal and which, if continued, would produce rough deposits. The pH value for strike and barrel plating is between 6.5 and 8.
