Title: Monitoring system for anti-skid brakes - has two regulator channels which change over when signal duration exceeds threshold
Inventor: RUHNAU GERHARD
IPC: B60T8/96
Filed: 1977-02-11
Abstract: Each regulator channel has a recognition circuit consisting of a comparator stage, a timer and an OR-gate. The recognition signal outputs together with the regulator channel outputs are fed to a logic circuit controlling the respective brake circuit valves. The two comparator stages produce a high signal when the negative input is less than the positive input, otherwise both outputs are low. One comparator produces a high signal, when the second recognition circuit sensor runs faster than the first sensor. A difference exceeding a pre-determined duration is regarded as an error and the time produces a high signal. The high signals are passed to AND-gates to change over the regulating signals from the first channel to the second channel.

Patent DE-2752377-A1 (DE)
Inventor: AICHELMANN JUN FREDERICK JOHN
IPC: G11B20/18
Filed: 1977-11-24
Abstract: A parity checking scheme for detecting memory array word line failures whereby all of the data and parity bits of a plurality of bytes sharing the same word line erroneously assume the value "1" or the value "0". When storing data in the array, the data and parity bits comprising each byte are stored directly except for the parity bit of a selected one of the bytes, which parity bit is inverted by a gated inverter circuit before storing. The same gated inverter circuit also inverts the parity bit of the selected byte upon reading the stored data. All of the remaining bits of all of the remaining bytes are read directly. The read bits of each byte are applied to a respective parity checking circuit of the same even or odd parity type as is used in storing the data. The outputs of all of the parity checking circuits are applied to error control logic.

Title: Cellulose filter materials - having a high proportion of pores of uniform size
Inventor: MALEV OLEG ALEKSANDROVITSCH
IPC: B01D39/18
Filed: 1977-12-28
Abstract: Filter materials based on cellulose-contg. raw materials are claimed which contain pores of 0.1 to 120 mu m. The material contains 60-85 vol. % pores of 5 to 40 mu m whose diameters differ from each other by at most 5 mu m. The materials are made e.g. by milling a previously comminuted cellulosic raw material in an air medium in a concn. of at least >=80% (on dry material) until the average length of the cellulose fibres is 0.3-2.5 mm. The resulting fibres are dispersed in water at a concn. of 1.5 - 6% to form a homogeneous suspension, and natural and/or chemical fibres and substances and hydrophobing agents are added. The resulting mixt. is cast and formed into a web, pressed and dried to form the filter material. The high proportion of pores of homogeneous size gives filters with excellent retention properties coupled with high permeability. The filters are useful in internal combustion engines, dust traps, air conditioning units, purification of oil, filtration of edible liquids and chemical products, etc.
