Title: Ball joint for light fitting combined movements - has spring loaded split ball with groove and stop for cable protection
Inventor: GOETZ JOHANNES
IPC: F21V21/30
Filed: 1975-08-30
Abstract: The ball joint for light fitting enables the connected component to be tilted and rotated. The power supply cable passes through this ball joint which is used for adjusting light sources and reflectors of table or standard lamps. A spherical body (1) consists of two split spherical segments with groove (4) almost around the whole circumference of the segments. A small ball (5) is fitted into this groove and this ball projects also into a groove in the housing (6) and prevents excessive rotation. A mounting tube (8) is clamped between the spherical segments and the housing is held within an enclosing tube. The ball joint is loaded by the helical spring (11) and a loading ring (10). The mounting tube can be rotated through full circle and tilted through a half full turn.

Title: Balanced slide ring seal for shaft in housing - has one seal coupled to housing and another to shaft which passes through housing
Inventor: WIESE WINFRED JOHN
IPC: F16J15/34
Filed: 1976-10-18
Abstract: Balanced side ring seal which can be used along or together with one or more additional ring seals in a tandem or double seal arrangement has a housing with an opening (15) for a shaft (17). A first ring (19) is coupled to the housing (10) and a second ring (28) is connected to the shaft.

Title: Four stroke engine charged by crankcase pressure - has inlet valve regulating transfer channel inlet
Inventor: METZGER KLAUS
IPC: F02B33/26
Filed: 1977-03-01
Abstract: The four stroke engine uses a crankcase pressure as a pre-compressor for the fuel air mixture. The crankcase is designed as small as possible so that the volume is considerably less at piston bottom dead centre than that of the cylinder swept volume. The engine has a fuel/air mixture transfer pipe (33) which starts at a transfer port in the cylinder wall and terminates at an opening on the cylinder head. The opening is regulated in the conventional four stroke manner. The piston has an opening (26) just below the crown, opposite the transfer port (32) at piston bottom dead centre. The transfer pipe (33) volume is equal to the cylinder swept volume and acts as a mixture storage chamber. The fuel/air mixture is drawn into the crankcase via an intake pipe (31) and an inlet port (29). The inlet port is in the cylinder wall just below the lower piston skirt edge when the piston is at top dead centre.
