Abstract: A method and apparatus (12) for cold sizing a round workpiece (14) having round surfaces of cylindrical shapes that are coaxial about a central axis A of the workpiece and have different diameters. A support (54,55) rotatably mounts the workpiece (14) about its central axis A between a pair of die assemblies (24a, 24b) which are spaced from each other. Each die assembly (24a,24b) includes a plurality of dies (56,58,60,62) that are respectively aligned with the round surfaces (46,48,50,52) of the workpiece (14). Movement of the die assemblies in opposite directions as each other engages sizing surfaces (66,68,70,72) of the dies with the aligned round surfaces of the workpiece to pressure size the workpiece surfaces. In one embodiment of the sizing apparatus (12), the dies assemblies (24a, 24b) have elongated shapes and are moved rectilinearly in a parallel relationship to each other to perform the sizing. Another rotary embodiment of the sizing apparatus (12ʹ) includes rotary die assemblies (24aʹ,24bʹ) mounted by associated spindles (85) whose rotation likewise pressure sizes the round workpiece surfaces. Both embodiments of the sizing apparatus are disclosed as including forming projections for forming projections for forming projections such as splines (82) and/or a helical thread (84) on the sized surfaces of the workpiece.

Abstract: A vehicle brake system includes a check valve (24) having an input port coupled to a fluid pump outlet (14) and an output port coupled to hydraulically deactuated spring brakes (50) through brake lines. A pilot check valve (30) has a pilot port, an inlet port coupled to the input port of the check valve (24) and a return port coupled to the fluid reservoir (12). The pilot port is coupled to the output port of the check valve so the pilot check valve opens only when the output port is pressurized. This allows hydraulic fluid to flow from the pump (6), through the pilot check valve (30) and to the reservoir. To set the brakes when stopped or in emergency situations the operator actuates a valve (72) which dumps the fluid in the brake lines into the reservoir. A second pilot check valve has its pilot port connected to a brake pedal actuated master cylinder, its inlet connected to the brake line and its outlet connected to the reservoir. Pressing on the brake pedal connects the brake line to the reservoir through a variable restriction so to allow the spring brakes to be applied in the modulated manner of service brakes.

Title: Cleaning device for printing machines
Inventor: WAIZMANN FRANZ
IPC: B41F23/02
Filed: 1988-06-10
Abstract: A process and device for cleaning the rubber blankets of web offset printing machine while the web is running, wherein the washing agent (detergent) used for loosening the ink and paper residues on the rubber blanket is partly absorbed by the print web and passes on to the drier. During cessation of printing, on which a rising and then a falling ink-residue curve and a corresponding washing agent loading curve are superimposed, an undesirably high level of volatilisation can take place. The quantity of vapour can, on the one hand, be controlled by the washing programme. On the other hand, the quantity of vapour can be regulated by intervention in the volatilisation process by means of a substance applied to the surface of the web. The application of the substance inhibits the volatilisation, modifies the ratio of components of the vapour and, in addition, the volatilising components can be sealed in. Water is of prime importance as the relevant substance. A spray device is arranged at the entrance of the drying unit, which device is charged quantitatively and time-wise with the objective of producing the lowest possible concentration of explosive or harmful vapours.

Inventor: HRUSCH LOUIS C
IPC: B64C25/60
Filed: 1985-08-19
Abstract: Landing gear mechanism includes a built-in hydraulic actuator (30) which may be actuated to provide a heavy load range, soft spring rate during take-off with a heavy take-off weight and a lower load range, softer spring rate after take-off and prior to landing with a lighter landing weight to yield more shock strut stroke for a given range of vertical load during landing. A special taxi valve (45) allows for some fluid to bypass the main orifice (15) more freely to and from the lower piston damping chamber (54) to the shock strut air-oil chamber (20) as soon as the landing energy stroke is complete to greatly reduce or eliminate high damping loads that might otherwise take place as the gear negotiates bumps. Such a valve may automatically be set to close for landing by the action of the gear extension during a subsequent take-off, thus reactivating the main orifice. For normal bounce, air in the primary chamber (20) drives oil through an orifice (69) in a rebound damper valve (65) to the lower piston chamber (54) in order to lift the supported weight of the aircraft as part of the return stroke. However, when riding over a hole, the air acts freely on the differential or net piston area of the gear which is too small to lift the supported weight of the aircraft, but is large enough to accelerate the unsprung mass of the gear quickly into the hole. An anti-cavitation bypass valve (62) assures oil refill in the lower portion of the piston chamber as the gear extends. Also, a pressure actuated valve (71) may be provided in the metering pin (10) which, upon sensing cavitation in the lower piston chamber (54) during extension, will open a series of holes (72, 73) both above and below the main orifice (15), providing a flow path for oil around the main orifice, to eliminate the aforementioned cavitation. The metering pin is part of this flow path. A check valve (95) may be provided at the top of the metering pin to keep the metering pin full of oil by allowing free flow of oil upward but not allowing downward flow, thus preventing the intake and down flow of shock strut air during the anti-cavitation re-fill of the lower piston chamber. An extension snubber valve (116) may also be provided to develop piston rebound damping during the last portion of stroke of the landing gear before full extension thereof during take-off.
