Title: Improvements in and relating to the front forks of motor cycles
IPC: B62K21/02
Filed: 1924-07-04
Abstract: 224,203. Krauss, F. E. Nov. 2, 1923, [Convention date]. Forks of the type made from sheet metal, with strengthening-insertions for the axle bearings and the connections to the head, springs, &c., have each side formed from a symmetrical blank to which the strengthening-insertions are fixed before the blank is bent about its axis of symmetry to form the fork side. The insertions b, b<1>, c, c', d, d<1>, Fig. 1, are of different sizes and shapes, and when the blank a is bent to the form shown in Figs. 2, 5 and 7, and the edges united, the metal is fourfold at the strengthened parts. The insertions may be interconnected by a strut f, Fig. 3. In this form, one or both of the insertions d, d<1> may be extended to the front of the fork, as shown in Figs. 4 and 9, and connected by rivets &c. e to the bent-in walls of the fork side. An insertion g, Fig. 6, may be provided along the front of the side member. The insertions may extend into the hollow space of the fork side as at d<11>, Fig. 8, the parts d<11> if desired being bent either wholly or in part against the inner wall of the fork side. The part d<11> may comprise a series of tongues, which are bent alternately against the two walls of the fork side.

Abstract: 1,057,001. Heat-exchange tubes; steam generators. CLEAVER-BROOKS CO. April 17, 1964 [July 1, 1963], No. 16135/64. Headings F4A and F4S. A boiler comprises a cylindrical chamber 13 forming a water chamber 25 closed by tube sheets 20 and 24, and between which extends a corrugated fire tube 33 and inclined heat exchange tubes 48, each having linear arrays of indentations on their opposite side walls arranged in a horizontal plane. At one end of the fire tube is arranged an oil burner 31 having a nozzle 34 which is supplied with air by a fan 25, the air being forced against impeller fans 35. The combustion gases pass down the fire tube 33, which gradually decreases in section to maintain a constant gas velocity as the gas cools, to a manifold chamber 51 formed by a refractory end cap 14. The gases are then directed through tubes 48 to outlet chamber 49. A pressure release valve 50 is fitted to the manifold. The chamber 25 is fed with water through inlets 28 and steam escapes through outlet 29. The tubes 48 are arranged in arch array (see Fig. 2, not shown), and their inclination allows for drainage by gravity of any condensate. The indentations which provide turbulence of the combustion gases in the tubes 48 may be staggered along opposite side walls and gradually increase in size, Fig. 6 (not shown), or become closer together to compensate for the reduction in volume of the combustion gases due to cooling.

Title: Process of cleaning-wool using detergent compositions
Inventor: PAYNE JOHN
IPC: C11D1/831
Filed: 1952-06-27
Abstract: For cleaning processes effected under acid conditions, use is made (after appropriate dilution) of a liquid detergent composition comprising an aqueous solution of an alkylaryl sulphonate and an alkylene-oxide surface-active agent, the concentration of the alkylaryl sulphonate being greater than the maximum obtainable, under otherwise identical conditions, in the absence of the alkylene-oxide surfaceactive agent.  The alkylaryl sulphonate may be sodium dodecylbenzene sulphonate and may contain a builder, e.g. a sodium phosphate or sodium sulphate.  The alkylene-oxide surfaceactive agent may be a reaction product of an alkylene oxide, e.g. ethylene oxide or propylene oxide, with an alcohol, a phenol, a carboxylic acid, an amine, an amide or a mercaptan containing a group of 8-25 carbon atoms.  Specified alkylene-oxide surface active agents are the products sold under the Registered Trade Marks Lubrol and Nonex, and reaction products of ethylene oxide with wool grease, dodecylphenol, octylphenol, polyethylene glycol fatty acid partial esters and a mixture of aliphatic amines of 16-18 carbon atoms.  The solutions may contain 15 per cent or more of alkylaryl sulphonate and, after dilution, are useful for washing wool and other materials under acid conditions, e.g. in the presence of a little acetic acid.  Examples are given.

Title: Photographic treatment for semiconductor devices
Inventor: AKIYAMA KATSUHIKO
IPC: H01L23/29
Filed: 1969-03-28
Abstract: 1,224,826. Etching. SONY CORP. 28 March, 1969, No. 16483/69. Heading B6J. [Also in Division H1] Electrodes of a semi-conductor device are made by depositing a suitable metal layer on the semi-conductor wafer of a device or on a substrate on which it is to be mounted, applying a positive photoresist over it, exposing first portions to light and developing to remove them, then exposing second portions to form a latent image therein. The photoresist is then used as a mask in an etching or plating step prior to development of the latent image. The new mask resulting from the later development is finally used in an etching or plating step. Typically electrodes are formed on an oxidepassivated planar transistor structure starting with an overall aluminium layer which is, provided with nickel contact pad areas by overall deposition and form-etching. The positive photoresist is then applied, exposed and removed by development from the nickel pads and exposed again to form a latent image over the areas of aluminium which eventually have to be removed to form the electrode pattern. Next the nickel pads are built up by plating first with nickel and then with tin, using the aluminium layer as a plating electrode, plating through pinholes in the photoresist being avoided by a previous anodization of the aluminium or of a titanium layer disposed thereon. Then the latent image is developed to remove the photoresist from the dotted area 211 in Figs. 6A and 6B and the exposed aluminium etched to leave electrodes as shown. Heating is effected to form the tin plating into globules which are finally plated with silver. A similar process is used to make beam lead connections between parts of a semi-conductor wafer. In this case the nickel is applied at the beam lead locations and reinforced in the plating step with a 10- 15 Á layer of nickel or gold. After etching to remove aluminium remaining between the leads the body is pattern etched from the back face to air-isolate the sections of wafer connected by the beam leads.

Abstract: 694,865. Centrifugal separators. SULZER FRERES SOC. ANON. July 3, 1950 [July 12. 1949], No. 16538/50. Class 23 Particles of liquid are removed from moist air by introducing the air .into a separating chamber and causing it to whirl to produce centrifugal separation of some of the liquid particles, and then passing the air upwardly through a tube leading from the separating chamber at an average velocity not exceeding the terminal velocity of descent of the liquid particles through still air at the same pressure and temperature. Preferably the upward velocity of the air does not exceed 10 metres per second. Suitable apparatus comprises chamber 7 into which air is introduced tangentially through pipe 2 at a point not more than half-way up the chamber. Liquid flows down the walls of the chamber and is removed at 9. The air passes through tube 16, preferably of a height at least as great as the height of the chamber 7, and then to a smaller tube 18. The apparatus may operate at atmospheric pressure or at lower or higher pressures, and may be installed in a system in which air from the suction box of a paper-making machine is dried and recirculated.

Title: Underwater explosive devices
IPC: F42C5/00
Filed: 1976-04-23
Abstract: 1502032 Underwater explosive devices AMADO LAGUNA DE RINS SA 23 April 1976 [24 April 1975] 16575/76 Heading F3A Relates to an underwater explosive device which comprises a main charge, a priming charge surrounded by the main charge and a fuze operable by a predetermined pressure of water surrounding the device to detonate the priming charge. According to the invention the fuze comprises a spring-loaded detonator, means for retaining the detonator in an inoperative position spaced from the priming charge, means operable by a diaphragm exposed to the pressure of the surrounding water to release the detonator for operation by its spring, and safety means which prevent accidental operation of the device, and must be removed to render the device operative, the safety means comprising a first member which seals the fuze against the admission of water to the diaphragm and a second member which prevents the diaphragm from deflecting under pressure. In an embodiment water is prevented from entering the interior by screw cap 3 and the second safety device 37 has to be removed to permit diaphragm 6 to drop as hydrostatic pressure increases. As the diaphragm drops, piston 35 progressively overcomes the resistance of spring 15 and, as the piston descends, step 34 eventually passes balls 13; spring 15 is launched with its detonator 17 against percussion pin 21 and main charge 23a explodes after booster charge 22. To vary the depth at which explosion occurs the dstance between the bottom of piston 35 and its step 34 is altered, or spring 15 is altered in length or strength. The device can be neutralized by bores 9, 12 which are filled with water-soluble material, e.g. soap.

Abstract: 738,433. Hopper discharge. VITAMINS, Ltd. June 16, 1954 [June 17, 1953], No. 16756/53. Class 78 (1). Apparatus for intermittently delivering charges of material comprises a hopper 10 having a hingedly mounted flap 15 in the base thereof which is capable of being held in its closed position (e.g. by latch 32) to support the charge of material and in which poweroperated means 18 are provided which serve for releasing the flap to allow the charge to be delivered under the action of gravity and also for subsequently positively opening the valve whenever the action of gravity is insufficient to open the valve fully. As shown, a reversible motor is operatively connected to shaft 16 on which are fixed wheel 42 carrying stud 44, and arm 38. The motor is started by pressbutton so that pulley 18 rotates, and through tooth 20 fixed to said pulley, gives a jerk to rod 22 which, through the linkage 27 withdraws latch 32 to allow flap 15 to fall under the weight of discharging material. Pulley 18 continues to rotate so that, if the flap is not fully opened, bar 41 fixed to pulley 18 engages stud 44 of eccentric 42 fixed to shaft 16 to cause the latter to rotate further. This completes the opening of the flap till arm 38, rotating with the shaft 16 strikes a switch 40 and cuts off the motor. When the motor is reversed the flap 15 is closed and arm 38 strikes a second switch 40 to again cut off the motor. In order to prevent a back rush of air from the chamber into which the material is discharged from the hopper a duct is provided which connects the chamber with the hopper.

Title: Improvements relating to braking systems
IPC: F16D65/22
Filed: 1931-06-09
Abstract: 380,442. Fluid-pressure brakes; band brakes. PUGH, J. V., Meriden House, Meriden, Warwickshire. June 9, 1931, No. 16811. [Class 103 (i).] Relates to vehicle fluid-pressure braking systems wherein, when a predetermined pressure has been reached after an initial application of the brakes, a greater braking force is applied to the front wheels than to the rear wheels on continued application. In the pressure-transmitting unit for the rear-wheel brakes, the piston 18, Fig. 1, is moved to expel liquid from the cylinder 1 by a force transmitted by the brake pedal or the like through an initially compressed spring 19 while the piston of the unit operating the front-wheel brakes is acted on directly by the brake pedal. The piston 18 forces the liquid through a duct 14 in a spring- pressed check-valve 6 and through a spring- pressed mushroom valve 10 to outlets 3, 4 leading to the rear-wheel brakes. On release of the brakes the valve 10 closes and the fluid returns by forcing the valve 6 from its seating 7. An opening 23 in the cylinder 1 permits the entrance of oil from the container 2 when necessary and to prevent a vacuum forming within the piston on its return stroke, a byepass 24 is provided to permit exit of liquid from the piston. The rocking shaft actuated by the pedal may have four arms similar to the arm 22, Fig. 1, for simultaneous operation of four-wheel brakes. Fig. 3 shows wheel brake apparatus which is similar to that described in Specification 376,905. The piston of the pivoted cylinder 31 is connected to levers 34, 35, movement of which towards the positions shown dotted causes the separation of the ends of the brake band. One of the front-wheel braking arrangements described in Specification 265,656, [Class 103 (i), Brakes &c.], may be used in combination with the means above described for the rear-wheel brakes.
