Title: Improvements in or relating to cages for rolling bearings
IPC: F16C33/56
Filed: 1933-06-23
Abstract: 400,890. Ball-and-roller bearings. BOSCH AKT.-GES., R., 4, Militõrstrasse, Stuttgart, Germany. June 23, 1933, No. 17905. Convention date, July 15, 1932. [Class 12 (i).] A spacing cage for the balls or rollers of a bearing is made by winding woven fabric, impregnated with artificial resin, into annular layers and subjecting it to axial compression, the fabric being then heated under pressure. The axial pressure causes the fabric layers to crinkle or loop together to strengthen the structure. The recesses for the balls or rollers may then be formed in the resulting blank. Apparatus for forming a cage in which the ball recesses are formed during the moulding process is shown in Fig. 3. The impregnated fabric layers a<1> are arranged between a core h and sleeve l and die members i, m. The latter have projections r, s, to form recesses p, o, Fig. 4 in the cage, and springs k are arranged between the sleeve l and presstable g. The projections r, s, may be slightly conical, or convergent downwards or upwards, so that in the finished cage the balls do not drop out of place, the resiliency of the fabric permitting the projections r, s, to be withdrawn.

Title: Method of and apparatus for conditioning steam
IPC: F22G5/12
Filed: 1972-04-18
Abstract: 1385975 Direct contact cooling of steam R E SELF 18 April 1972 [26 May 1971] 17926/72 Heading F4K [Also in Divisions F2 and G3] A device for conditioning steam by introducing cooling water into the steam and thereafter reducing the steam pressure, comprises a stack of annular discs 9 offering a plurality of labyrinth passages therebetween for steam flowing from an inlet 8 to an annular chamber 10 and outlet 11, the volume of such steam flow being controlled by means of a plug valve 14 movable within the stack. The reciprocable movement of the plug is controlled by an actuating head 17 in the form of a follower which is adapted to be operated by a suitable cam device responsive to steam pressure at or adjacent to the inlet 8. The arrangement ensures a uniform steam-pressure-responsive flow rate through the disc stack 9. Steam temperature reduction is achieved by supplying cooling water to the steam prior to the latter entering the disc stack 9, the supply being by way of passages 23, 20 and 18 leading to an orifice 19. The size of the orifice 19 is determined by the relative disposition of plug 14 and a fixed tapered metering pin 24, such size at all times ensuring a water flow rate proportional to the steam flow rate. On leaving the orifice 19, the water is distributed over 360 degrees.

Title: Method and apparatus for compacting a mould forming material in a rotating flask
IPC: B22D13/10
Filed: 1956-06-11
Abstract: 808,346. Moulding-machines centrifugalcasting-machines. HERMAN PNEUMATIC MACHINE CO. June 11, 1956 [Nov. 1, 1955], No. 17943/56. Class 83 (1). Mould-forming material in a rotating hollow flask is compacted by subjecting it, during rotation of the flask, to a succession of blows at circumferentially spaced-apart portions of the flask. The apparatus is similar to that described in Specification 808,345 which is referred to, but the mandrel has an eccentric portion 25f which, as the mandrel turns about its axis, strikes the mould-forming material with repeated blows, and thereby consolidates and smooths it without substantial bending or deflection of the mandrel, which is so slender that, if pressed continuously against the mouldforming material, it would bend inwardly. It is found that the mandrel does not strike the mould-forming material at the same points at each revolution of the flask so that a uniform cylindrical, rather than a fluted, mould is formed. Specifications 650,683 and 658,403 also are referred to.

Title: Table model ironing machine
IPC: D06F65/04
Filed: 1951-07-30
Abstract: 723,322. Ironing-machines. BEATTY BROS., Ltd. July 30, 1951 [June 16, 1951], No. 17949/51. Class 138(2). An electric ironing-machine comprises an ironing roll 11 supported by a base 10, an electric switch 22 for energizing an electric motor (not shown) for rotating the roll 11, an electrically heated ironing shoe 12 mounted on a shaft 13 for movement into and out of engagement with the roll 11 by means of a lever 15 connected to the shaft 13, an outer handle portion 26 of the lever being rotatable about the longitudinal axis of an inner portion thereof, a guide slot for guiding the handle portion and holding it against rotation when operated to move the shoe into and out of engagement with the roll, the guide slot having an enlarged portion 33a permitting the lever 15 to rotate in one direction to actuate the switch 22 after the lever has been operated to move the shoe into engagement with the roll and to rotate it in the opposite direction to release the switch 22 and de-energize the motor before the lever is operated to move the shoe out of engagement with the roll. The handle portion 26 is removably and rotatably received in a socket 27 formed at one end of the lever 15. The socket 27 carries a spring 29a which engages in a peripheral groove 29 in the portion 26. The top end of the slot is enlarged at 25a to enable the portion 26 to be removed when the shoe is out of engagement with the roll. The handle portion 26 is formed with a flat section 30 where it passes through the slot 25 and the latter is so shaped that when the lever is at the bottom of the slot it can be rotated through 45 degrees about its own axis. The outer part of the portion 26 is bent through about 3 degrees with respect to the flat section 30, as seen in Fig. 6, so that the rotation of the lever is effected automatically as the flat section enters the enlarged portion 33a of the slot. The upper edge 31 of the flat section 30 is thus brought into contact with a pushbutton 23 to actuate the switch 22. The bent lever 26 serves to lock the shoe in ironing position but slight upward pressure on the handle releases the flat section 30 from the portion 34a of the slot by rotating the lever and allows a spring 18 to move the shoe 12 away from the roller. The shoe 12 is carried by a leaf-spring 36 attached to a supporting member 34 connected by a pivot-pin 35 to an arm 14 fixed to the shaft 13. The ends of the spring 36 are received in slide-ways 39, 40 formed in each arm of two U-shaped members 38, 38a removably connected to the shoe 12. Bolts on the shoe act as stops to allow a predetermining flexing of the spring and then to allow the full pressure to be exerted on the shoe. The electric motor is mounted in a cylindrical member 19. Reference has been directed by the Comptroller to Specification 524,668.

Abstract: 1394576 Regulating I C engine operation O F MUNGUET 18 April 1972 [17 Nov 1971] 17951/72 Heading F1B An engine 2 is operable at will with a high compression ratio and limited maximum fuel consumption to provide a limited amount of pollutants in the exhaust gases or with at least one lower compression ratio, e.g. 5.2 : 1, and a supercharger 13 and unlimited fuel consumption. The compression ratio may be adjusted by moving the engine cylinder head (4), Fig. 2 (not shown), by rods (5) and eccentrics (6) as described in Specification 1262695. The fuel consumption may be limited by restricting the movement of the control rod (20), Fig. 4 (not shown), of the fuel injection pump (17) by means of a member (19) operable with the control lever 16 which varies the compression ratio. During high compression ratio operation the exhaust gases may be directed through exhaust clearing apparatus (23), Fig. 6 (not shown), e.g. catalytic, rather than the silencer 15 and lower octane fuel may be fed to the engine during this mode of operation. The motor vehicle 1 driven by the engine may have a signal 12 which is operated when the lever 16 is in other than the high compression ratio position or is operated by a radio signal which also causes the vehicle to reduce speed or stop.

Title: Process for the production of valuable liquid hydrocarbons by destructive hydrogenation of carbonaceous materials
IPC: C10G1/08
Filed: 1935-06-25
Abstract: In the production of valuable hydrocarbons by destructive hydrogenation of carbonaceous materials in the presence of acid substances or substances furnishing these under the reaction p conditions, the reaction products issuing from the reaction vessel or the separator connected thereto in a gaseous state are brought into contact with the liquid initial materials, the alkaline constituents of which are thus neutralized by the acidic content of the reaction <PICT:0443133/III/1> products.  Acidic materials may be added to the initial material, but only to such an extent that the coal &c. has still sufficient residual alkalinity to take up acid from the reaction products. Acidic materials, e.g. halogen compounds and particularly ammonium chloride and carbon tetrachloride may be added at suitable points during the reaction.  The coal may be freed from ash by froth flotation or float-and-sink methods and may be pasted with equal parts of heavy and middle oil obtained in the process. In the treatment of oil alone, if this does not contain sufficient alkaline materials such as pyridine bases, alkali metals or their compounds or brown coal coke rich in ash may be added thereto. Finely ground coal impregnated with ammonium molybdate and pasted with oil is brought in a vessel 4 into counter current with the gaseous reaction products from a separator 3.  Part of the middle oils used in the pasting are vaporized and pass with the gaseous products through a heat-exchanger 5 and cooler 6 to a separator 7 where condensate is separated from the gases which are recirculated by a pump 8 through the heater-exchanger 5 to a preheater 1 where they mix with the coal paste supplied by a pump 9.  The mixture passes to a reaction vessel 2 from which the reaction products flow to the separator 3 from the bottom of which solid and high boiling point products are withdrawn.  Carbon tetrachloride is added to the mixture before entry into the preheater.  The temperature in the heat-exchanger 5, preheater 1, and reactor 2 are 340, 440, and 460 DEG  C.  Specification 359,661 is referred to.
