Title: Metering pump for fuel injection engine - using rotary distributor driven by stepping motor contained in stationary outlet housing
Inventor: DILGER PETER
IPC: F02M41/16
Filed: 1979-05-29
Abstract: The principal objective of the proposed metering pump is the elimination of solenoid operated injector valves, thus giving a saving in electrical power requirements. The pump comprises a stationary housing (32) with the necessary number of outlets (33-36). Inside the housing rotates a distributor (30) in the form of a cylindrical sleeve with an open end, having a notch (31) in its circumference. Fuel is fed into the assembly through an inlet (24). As the distributor turns, driven by a stepping motor (17), the notch passes each outlet in turn and allows a specific amount of fuel to pass through. The fuel quantity depends upon the supply pressure, the speed of the distributor revolution; and its axial position relative to the outlets. In extreme axial positions the outlets are either entirely blanked off, no fuel, or fully open, maximum fuel. The motor (17) speed can be controlled from an electronic installation forming part of the engine control system.

Title: Domestic telephone communication system - uses microprocessor control which switches extension to exchange bus=bar for ringing
Inventor: FAHRENSCHON FRANZ DIPL ING
IPC: H04Q3/62
Filed: 1979-09-13
Abstract: The telephone system for installation in a home allows one main and four extensions to make internal calls or use the exchange line. All telephones are normally switched to the house busbar. An internal call is made by lifting a receiver and dialling the called extension number. Other extensions can join in by lifting their receivers or can be called by dialling the numbers. The microprocessor switches the called extension to the exchange busbar and connects the ringing supply to it. When the called extension answers, the microprocessor switches it back to the house busbar. An incoming call on the exchange line is detected by the microprocessor, which switches the main to the exchange busbar and rings it. When the main answers, the exchange busbar is switched through to the exchange line. A loud bell can be switched on and an extension can answer an outside call by dialling the exchange code.

Title: Warp-beaming machine with single lifting jack - which operates both press-roller mechanism and beam lift-fork
Inventor: KOFLER WILHELM
IPC: D02H3/00
Filed: 1979-09-17
Abstract: A warp-beaming machine having a direct warp-beam drive, a press-roller to consolidate the beam, and a lifting fork to install the beam in the machine, has a single hydraulic cylinder which positions the press roller and also raises and lowers the warp beam. The press-roller arms and the lifting fork are attached to parallel shafts having inter-linked crank arms. The piston-rod of the operating cylinder is attached to a crank on the press-roll shaft, whereby a limited movement of the piston-rod raises the press- roller from the warp beam, without affecting the latter. Continued movement of the piston-rod engages the lifting forks with the beam-ends, allowing it to be lowered out of the machine. This construction is considerably simpler and less expensive than the provision of separate drive-units for each function. It is safer in use because the sequence of operations is fixed and cannot be attempted in the wrong order.
