Title: Hydraulic motor or pump with radial pistons - balances radial forces with hydrostatic pressure field
Inventor: FREITAG EMIL
IPC: F03C1/36
Filed: 1975-05-24
Abstract: The cylinder block (13) rotates on the cylindrical portion (38) of the flow control slide (40). The cylinders (15) house pistons (16) which are restrained by a polygonal ring (21) which provides a bearing surface for the slippers (17). The resultant of all the pressure loads on the cylinder block exerts a force R1 on the bearing surface of the portion (38) and the pressure in the delivery port exerts a force (D) on the slide (40). These forces are balanced by the force (E) due to the delivery pressure acting on a suitably large area (50) which is supplied with fluid at pressure through the hole (52). The position of the area (50) is such that the moments are also balances.

Title: Reed relay contacts for telecommunication circuits - increases sensitivity by coating contacts with ferromagnetic layer
Inventor: WESSEL GERHARD
IPC: H01H1/66
Filed: 1975-08-13
Abstract: Reed relay contacts are for use in telecommunication circuits. A tubular casing contains both contacts which have overlapping ends and an air gap between the ends. The contacts are spring loaded and they are engaged due to the magnetisation of the two ends to opposite polarities. The sensitivity of the switch is increased by coating the casing (1) with a layer (5) of ferromagnetic material. This will tend to concentrate the magnetic field in the air gap between the contact prongs (2, 3). The switch would then require a smaller response current in the excitation coils and a smaller gap between the contacts. This will increase the speed of operation.
