Title: Mountaineer's boots - have pre-shaped soles with vertical rim for glueing with adhesive to uppers
Inventor: LEDERER JOSEF
IPC: A43B5/00

Title: Hose clip for securing flexible pipe - radial pressure is applied to male adaptor end of machine part
Inventor: HECKER ROLF
IPC: F16L37/05
Filed: 1973-09-27
Abstract: Hose clip or coupling ring for joining flexible piping to machine parts with a male adaptor fitting, has an inner ring made of elastic material and a non-circular cross-section. Onto this elastic ring an outer ring made of non-stretch material such as steel wire is moulded into its side. By rolling the elastic ring along the surface of the pipe, deformation of the inner ring is achieved through the outer ring coming to the top squeezing the inner ring and thereby exerting uniform radial pressure on the hose. The cross-section of the steel wire is only a fraction of that of the elastic ring. When unstressed, the cross-section of the elastic ring is that of half an ellipse with the steel ring at the centre of the minor radius.

Title: Pressure supply for hydraulically operated gearbox - has moving spool valves to avoid pressure peaks during gear changing
Inventor: KOMATSU MITSUAKI
IPC: F16H61/06
Filed: 1974-01-10
Abstract: A pressure supply device has an inlet opening connected to a low pressure oil supply and an outlet opening that supplies pressurised fluid to an operating cylinder for the gear change mechanisms. A spool valve having several stepped diameters is placed between the fluid supply and the outlet and arranged so that gear selection admits low presure oil to the chamber and the oil drives the spool valve initially to the left to fill the cylinder. Subsequent pressure rise in the cylinder returns the spool valve to the right and via a passage applies pressure to a chamber which in turn operates a spring biased spool valve pump to generate a gradually increasing oil pressure which is communicated to the cylinder via a metering orifice in the spool valve.
