Filed: 1929-06-24
Abstract: 314,309. Peyinghaus, W., (trading as Eisen-und Stahlwerk W. Peyinghaus). June 23, 1928, [Convention date]. Centrifugal - action lubricating. - In a railway-vehicle axlebox, a disc b secured to the axle a has a conical rim d of which the smaller end, directed towards the bearing bush, is provided with one or more radial projections c which dip into an oil well and fling the oil centrifugally against the wall g of the box, whence it gravitates into channels m in the bush. The rear wall of the box is provided with a downwardly inclined rim d, so that surplus oil is kept away from the rib h which projects beyond the rear end of the axle. and drains on to the rim d and passes from the front edge e of the latter into the channels m. The rear edge f of the rim d is turned outwards and an arcuate groove k on the rear wall of the box catches any oil passing beyond the disc and leads it back to the wall.

Title: Control valve particularly for air jackets
IPC: B63C11/02
Filed: 1956-06-22
Abstract: 798,366. Diving. SVENSKA AKTIEBOLAGET GASACCUMULATOR. June 22, 1956 [June 23, 1955], No. 19404/56. Class 68(2) [Also in Group XXIX] An air jacket for use by a diver is provided with a valve which can be displaced to allow the admission of gas under pressure into the jacket and which automatically closes off the supply conduit when the volume of the jacket reaches a pre-determined value, and the valve is provided with an exhaust conduit which can be opened manually or by volume-sensitive means comprised in the air jacket when the pressure in the latter becomes excessive. In an embodiment, the inlet valve 5 is shown supported on shoulders 9 and with the gas supply conduit 10 closed off between sealing rings 6 and 7 carried by the valve. If the valve is pulled upwardly by means of a stem 11, the sealing ring 7 will clear the end of the supply conduit and gas will flow into the jacket 2. The part of the jacket opposed to the valve 5 is connected to the lower end of the stem 11 by a chain 21 so that when the jacket has distended sufficiently to tauten the chain, the stem will be pulled down and, through its agency of a spring 12, the valve will also be pulled down to shut off the supply of gas. The lower end of the stem passes through a vent aperture in the valve and carries a flange and washer 15 which normally seats on the valve and closes off the passage through which the stem passes. Should the pressure in the jacket become excessive with respect to the outside atmosphere the jacket will tend to distend further and a further pull will be exerted on chain 21 and flange 15 will be pulled away from the valve and allow some of the gas in the jacket to vent to atmosphere past the square sectioned lower end 11a of the stem.

The servo mechanism may be a vacuum servo and actuation of the valve 5 exhausts to atmosphere one side of the diaphragm to cause the fluid pressure difference across the diaphragm, a vacuum source 19 maintaining a vacuum at both sides of the diaphragm when the valve 5 is closed. In use fluid in pressure lines 9, 10 is pressurized by the master cylinder 6 when a brake pedal 8 thereof is depressed. The brake 1 is urged to the wheel 2 and, if the latter should lock, this is detected by the sensor 3 and the control circuit 4 opens the anti-lock control valve 5 to release the pressure on the brake and prevent skidding of the wheel. The rate at which breaking pressure is restored is controlled by the slide member 22.

[Class 100 (iv).] Ink supply.-A broad ink-ribbon such as is employed in an addressing-machine is supplied at a number of points with small quantities of ink by means of a roller or the like which is moved on operation of the machine and co-operates with means for transferring ink from a source to the roller. The device shown in Fig. 2 comprises a roller 34 having recesses 35 engaging star-wheels 28 mounted on spring-supported pivoted arms 27 dipping into ink contained in a well 18 which supports the roller and arms. The ribbon 13 passes over and rotates the roller, ink being picked up by the star-wheels and supplied by the roller to the ribbon along a number of lines. The recesses 35 are arranged in relatively staggered circumferential rows and preferably supply ink between the lines of contact of the types and ribbon. To allow spreading of the ink before the newly-inked part of the ribbon is employed, the device is arranged to supply ink after the ribbon has passed the printing position, and the roller-spindle 33 is mounted in slots 32 so that the roller is disengaged from the star-wheels when the feed is reversed. A pair of devices may be arranged on opposite sides of the printing position, the rollers being rendered alternately effective by reversal of the feed. The roller may have a groove at either or both ends for permitting the corresponding starwheels to remain stationary. The roller may consist of discs connected by rods or the roller may be formed with interrupted circumferential grooves receiving the star-wheels. In the device shown in Fig. 5, a well 45 supports geared shafts 47, 51 carrying a roller 44 and co-operating toothed or knife-edged discs 46. In the device shown in Fig. 7, a roller 54 has recesses 55 co-operating with the teeth 57 of discs 56 which are normally locked by the roller. Specification 278,943, [Class 100 (iv), Typewriters &c.], is referred to.
