Patent DE-1947615-B2 (DE)
Title: Logic circuit with magnetic cores - has less component by making write-in signals depend on certain read signals
IPC: H03K19/16
Filed: 1969-09-19
Abstract: A logic circuit with magnetic cores, as in the main patent, passes only write-in signals to part of the logic if the read signal of this part has to be regarded as the result of a logic process. During the quiescent state (no input) considerably fewer magnetic cores are written-into simultaneously which reduces the number of write-in pulse amplifiers as well as interrogate pulse amplifier. Fewer magnetic cores will also need demagnetising. Instead of being written-into by centrally produced write-in signals, the cores of part of the logic are written-into by the read signals of the cores of special write-in elements controlled by read signals from other parts.

Title: Cam for IC engine overhead valve - has back surface recessed below base circle to accommodate wear
IPC: F01L1/053
Filed: 1971-09-21
Abstract: The cam is mounted on a camshaft driven by the engine. As it rotates, it depresses a rocker arm which acts on the tappet head of the valve stem. The lobe (2) of the cam is laid out to give accelerated opening and closing of the valve. The back face (3) of the cam is set back below the base circle (1) of the cam by a distance (x) which exceeds the normal tappet clearance by an amount sufficient to allow for increased clearance resulting from normal wear. The transition section from the back face to the lobe is laid out to give constant velocity. The end part of the back face gives a velocity higher than that of the transition section.

IPC: G11B20/10
Filed: 1984-01-25
Abstract: In a system for recording and reproducing digital signals on a magnetic tape (2) by using a rotary head (1A, 1B), in which signals are recorded as a series of oblique tracks (5A. 5B) without guard bands, a pilot signal (P) that controls tracking alignment of a playback head (1 A, 1B) is recorded at a particular position in a specific pilot signal record region, independent from the information signal record region. The pilot signal (P) is arranged at first predetermined positions separated from the ends of the oblique tracks (5A, 5B) in the pilot signal record region on every other one of the oblique tracks (5A. 5B) and at second predetermined positions separated from the ends of the oblique tracks (5A, 5B) in the pilot signal record region on the alternate ones of the oblique tracks (5A, 5B). An erase signal (E) can also be recorded in the pilot signal record region such that a start position of the erase signal (E) corresponds substantiallyto a centre portion of the pilot signal (P) on the adjacent oblique track (5A, 5B). When the recorded oblique tracks (5A. 5B) are reproduced by a rotary playback head (1A. 1B) having a tracking width greater than the track width, the pilot signal (P) from the adjacent oblique tracks (5A. 58) will be detected and compared in level, and the comparison output used to control the tracking alignment of the rotary playback head (1A. 1B).

IPC: C07C255/12
Filed: 1989-01-26
Abstract: The enzymatic reaction of aliphatic, aromatic or heteroaromatic aldehydes or ketones with hydrocyanic acid to give the corresponding (R)-cyanohydrins or (S)-cyanohydrins is carried out in aqueous medium in the presence of (R)-oxynitrilase (4.1.2.10) or oxynitrilase (4.1.2.11) under conditions which are sufficiently acid and at temperatures such that the chemical competing reaction and the racemisation are negligible compared with the enzymatic synthesis. The process is preferably carried out at pH values </= 4.5 and, in particular, at reaction temperatures between -5 DEG C and +50 DEG C. The reaction is preferably carried out continuously, especially in an enzyme membrane reactor. The reaction of aromatic aldehydes to give the corresponding optically active cyanohydrins is of particular interest.

Granted: 2004-05-24
Abstract: PROBLEM TO BE SOLVED: To control the directivity microphone so that a detection rate of a silencing detection block of a silencing detector is increased when plural microphones are arranged and the sensitivity gets higher at a talker's position. SOLUTION: The equipment is configured that plural microphones MICa-MICc are arranged on a plane and outputs of the microphones MICa-MICc are summed via delay circuits 2, 3, 4 respectively to obtain an output. A silence detection function section 13 obtains a ratio of a correlation between the microphone MICa-MICc outputs with respect to a prescribed time difference between the signals to a correlation with respect to a time difference between signals corresponding to a set sound source position and detects the presence of a sound source at a set position when the ratio satisfies a predetermined threshold condition so as to discriminate silencing/sounding.
