Inventor: BORDEN BRUCE S
IPC: G06F3/153
Filed: 1989-05-11
Abstract: An apparatus and method for dual mode presentation of color information to a red-green-blue color display in a computer system. The present invention is especially useful in a computer system supporting a windowing environment and allows for presentation of either true color or pseudo-color information to each window of the display independent of the color mode of the other windows being displayed. The present invention further allows for double buffering of color information and control of the double buffering on a window-by-window basis. The pixels of the display are arranged in groups (202, 204) for more memory efficient control of color. Plural mapped memories (101) allow for double buffered storage of group true or pseudo color information and a separate memory allows the mode selection control of these mapped memories. Various bit sharing configurations are described. <IMAGE>

Title: Sealing joint between mains drain and house connection - involves resin-impregnated insert, placed into house pipe without excavation of ground
Inventor: GUENZEL WILFRIED DIPL ING
IPC: E03F3/06
Filed: 1989-09-06
Abstract: The watertight joint is formed at the junction of a mains drainage pipe (4) and household waste pipe (5) in an underground location. A satisfactory joint keeps the surrounding ground area free of unhygienic seepages and the ingress of earth will be prevented thereby preventing the mains drainage pipe from becoming blocked. A lining and mould component (1) is placed into the household waste pipe (5) at an inspection chamber or access point. The lining and a mould component (1) is pushed into the main  drainage pipe (4) by means of a hollow pipe tube which is constructed of GRP. The lining and mould component (1) is now pulled back so that the tube section (3) is situated in the entry area of the household waste pipe. A pliable inflatable bag is also placed so that the sides of the bag expand to fill the spaces between the mains drainage pipe and the household waste junction. The lining and mould component is constructed of a fibrous woven material which is impregnated with a self hardening synthetic epoxy resin. The resin will now form the shape of the inside of the pipe connection and thus cause a satisfactory joint  to be formed. The inflatable bag will then be removed. Provision is made for the use of liquid or gaseous filling in the bag to be activated through thermal reaction of the epoxy compound. USE - Repair of defective underground pipe joints esp. for domestic drainage points.

Patent DE-4104144-A1 (DE)
Inventor: MAAS JOACHIM DIPL ING
IPC: B60T8/42
Filed: 1991-02-12
Abstract: The invention relates to a hydraulic braking system with anti-lock control, especially for motor vehicles, with a brake pressure sender unit (18), at least one wheel brake (5), an auxiliary pressure pump (1), a low-pressure store (22) and an isolating and outlet valve (12, 7) for controlling the braking pressure. The arrangement of defined restrictors (3, 4) in the region of an actuated differential piston (2) provides a permanent hydraulic connection between the auxiliary pressure pump (1), the wheel brake (5) and the electromagnetic outlet valve (12). By minimising the basic circuitry and especially the electrical control structure it is possible to do away with the need for electromagnetic inlet valves allocated to the wheel brakes without having to accept any penalties with respect to pedal operating convenience and the reliability of the braking system if the auxiliary pressurising system should break down.
