Title: Saddle kneading mill for rotationally symmetrical workpieces - has extra ram with stroke adjustment taper strips for aperture reduction
Inventor: MUELLER OSKAR
IPC: B21J7/16
Filed: 1975-09-17
Abstract: The kneading machine is for mechanical working and forging of mostly rotationally symmetrical workpieces. The saddle kneading machine has an additional external ram for radial openings in the workpiece, and lie in the same direction as the oscillating strokes. There are stroke-adjusting strips (4) projecting into the external ram (3) to limit the working strokes of the workpiece (1). The ram (3) strips (4) taper axially towards the interior, so that when the ram is withdrawn, the whole assembly remains in the idling position without radial oscillation against the rollers (5). The mill reduces the workpiece aperture size, and a suitable ram and strip taper combination gives the desired stroke.

Patent DE-2549376-A1 (DE)
Inventor: KOLLMEDER MICHAEL
IPC: A63C11/08
Filed: 1975-11-04
Abstract: The ski waxing appliance has a beaker-shaped heatable wax container (7), moulded onto which is a guide and wax-distribution surface (8). Located in this surface is a spring-prestressed valve (9) which the bearing pressure during waxing causes to open and through which the wax from the wax container can emerge onto the underside of the wax-distribution surface. A rivet (21) is used as the valve body, between the head of which rivet and the top side of the wax-distribution surface an O-ring (22) is inserted as sealing element. Ahead of the guide and wax-distribution surface in the working direction the appliance is fitted with a preheating plate (11) which can be heated together with the wax container by a heating device (2) and thus makes it possible by pushing the appliance over the running surface of a ski just once to provide the running surface with a thin, evenly distributed wax layer which adheres well thereto.   <IMAGE>

Title: Four stroke engine performance regulator system - has no throttle valve, and fuel volume is automatically load dependent
Inventor: BAZEN WILLIAM N
IPC: F02B19/10
Filed: 1976-09-04
Abstract: Engine has ante chamber flame channel ignition and is primarily designed for application with portable tools. The ante chamber (15) receives a fixed volume of easily ignitable fuel mixture via a separate feed (16) regulated by a sprung depression dependent poppet valve (17). A constant air volume mixed with a metered fuel quantity enters the main combustion chamber via mechanically operated inlet valve. The fuel is metered to the main combustion chamber by a taper needle valve. The taper needle shaft is provided with an external thread so that by turning the shaft the fuel jet cross section can be varied. The shaft is joined to a pivoted blade which is subjected to air pressure from the cooling fan. A spring acting against the pivot arm strives to keep the needle valve open, whilst the blade in dependence of air pressure from the cooling fan strives to close it. No throttle valve is required.

Title: High level fluid pumping - is for water storage system utilised in hydroelectric power generation
Inventor: KLIMBURG GEORG DIPL ING
IPC: F04B19/20
Filed: 1976-11-03
Abstract: The system achieves high head pumping operation with an improved efficiency, using positive displacement pump. The basic idea of the proposition is that the prime mover does not constitute a gap in the closed vessel system, but functions as a moving part of the surrounding vessel shell. This results in an improved efficiency, lower losses and an extended scope for application, as far as utilisation of large heads in storing operations, as well as utilisation of thermal energy, is concerned.
