Patent DE-1472055-A1 (DE)
Inventor: JOHN PRESTIGIACOMO ANTHONY
IPC: G01R23/00
Filed: 1965-06-01
Abstract: 1,102,779. Recording and playback. WESTERN ELECTRIC CO. Inc. 27 May, 1965 [5 June, 1964], No. 22516/65. Heading G5R. [Also in Division G1] In an apparatus for analysing complex signals carried on a magnetic tape 101 (Fig. 1) a portion of the tape is fed from a reel 10 to a supply reel 21 via sensing head 12 and periodically stopped on the periphery of a drum 17 and repeatedly scanned, by a head rotating inside the drum. During each rotation at a particular stop, the output signal is modulated by a different frequency, the resulting beat frequency being filtered by a fixed frequency filter, to provide an output corresponding to a particular frequency in the spectrum of the original signal. The selected portion of tape is clamped under tension at each step, it being arranged that the operation of the tensioning system is delayed relative to the clamp at each stop. The tensioning and clamping system is released and the record advanced by a preselected interval after the portion has been analysed in order to select the next contiguous portion of the record. The outputs are successively recorded by a stylus 22 on a record 39 carried on a drum 23 rotated in synchronism with the rotating head. The amplitude of a mark on the record 39 corresponds to the signal amplitude at any particular frequency, the frequency corresponding to the position across the medium, while distance along the medium corresponds to time. A more detailed description of the operating system circuitry is given (see Division G1).

Title: Single chamber high pressure bottle-filler valve - has fluid valve which opens itself or by lever foce and with adjustable valve lift
Inventor: BAATZ UDO DR ING DR
IPC: B67C3/06
Filed: 1973-12-06
Abstract: The single chambe high pressure bottle-filling machine fill valve has a central feed and back gas tube terminating at the top in a machine operated gas valve, which opens in response to shaft lift and connects at the bottom end to the spring loaded disc type fluid valve. This fluid valve can open of its own accord or under positive control. The force of the spring responsible for opening and the fluid valve should be greater than the weight of the moving masses involved. Forcible or positive control of the fluid valve should derive from levers exerting a friction force in excess of the valve spring. The extent of lift completed by the valve should be adjustable by means of a plunger which reaches down to adjusted depth in the fill chamber, to engage a stop fitted to the gas tube or to the main valve body.

Patent DE-2403007-A1 (DE)
Title: Two stage hydraulic relief valve - having main spool which carries spring biased pilot stage to provide damped operation
Inventor: LANG ARMIN
IPC: F16K17/10
Filed: 1974-01-23
Abstract: A two stage hydraulic relief valve provides damping and reduces dependence upon flow variations. The main spool carries a pilot stage spool which is spring biased against a retaining ring and the complete spool assembly is forced left wards against the inlet port in the neutral position. When the supply pressure is below the spring rate setting the pressure is the same on both sides of the spool. When the pressure exceeds the preset value the pilot spool moves rightwards and the spring side of the spool discharges flow to exhaust through the control port to outlet. The pressure then falls on the spring side of the spool and a differential force across the spool results in a movement of the main spool right wards. Pressure reduction then occurs directly from inlet to outlet over the main spool.

Title: Simultaneous prodn of low- and highly- doped regions - in silicon semiconductors using partial coating of oxides
Inventor: KOENIGER MAX DIPL PHYS DR
IPC: H01L23/29
Filed: 1974-02-16
Abstract: Both low- and highly-doped regions in a semiconductor crystal are obtd. by controlling and restricting, but not precluding, the diffusion into the region of silicon requiring a low concn. of the dopant by a layer of SiOx on the surface of the Si substrate while, simultaneously, the region requiring a high concn. of the dopant is subjected to diffusion without the intervening layer of SiOx, i.e. through a window. The restricting layer may consist of SiO (sic) obtd. by thermal oxidn. or siOx obtd. by reactive cathodic sputtering, reactive vapour deposition or by anodic oxidn. Used for mfg. integrated circuits, field-effect transistors, and high frequency- or pedestal-transistors. A single diffusion cycle can be used to produce both regions, thus substantially reducing mfg. costs. The SiOx layers are used not only for passivation but also to control the surface concn. of the dopant. The region (I) which requires a low concn. of dopant atoms is covered with a thin, homogeneous layer of SiOx (II) and by varying the thikness of (II) the amt. of diffusion into (I) is controlled while a high concn. is obtd. through a window; the remaining areas which are not to be doped are covered with a mask of SiO2.
