Patent DE-2741546-A1 (DE)
Title: Gas pipe leak monitoring system - where differences between successive pressure measurements are fed into computer emitting alarm in case of large differences
Inventor: WOLTER MANFRED DIPL PHYS DR
IPC: F17D5/02
Filed: 1977-09-15
Abstract: The system monitors gas pipes for leaks, partic. those handling gas at a pressure of >10 bar, by checking the pipe pressure. This pressure is measured at intervals of from 1-1000, pref. 60-360 seconds, and the results converted into a readable input value for a computer in which it is stored. A differential valus is obtd. from two successive measurements, and compared with a permissible discrepancy fed into the computer, and if this is exceeded continuously over a time interval also fed into the computer the differential values are stored. An alarm is emitted by the computer if the differential value between two successive measurements of pipe pressure exceeds an amt. >1 bar, 3-9 bar, which can be freely selected, extrapolated over 1 hr., or if differential values of all successive measurements within a time interval fed into the computer reach or exceed a predetermined discrepancy.

Title: Yarn splicing device for spinning frames - having a vortex chamber with intermittent air-jets of variable intensity
Inventor: ZUMFELD HEINZ
IPC: B65H69/06
Filed: 1978-11-27
Abstract: A device for automatically splicing the ends of a broken yarn on a spinning or winding frame comproses a vortex chamber in which the yarn ends are laid alongside each other and the fibres intermingled by means of intermittent blasts of air into the vortex chamber, which can be varied in strength and duration according to the type of threads to be joined.

Title: Yarn metering drum with balloon inhibitor - of flexible bristles bridging the yarn offtake aperture
Inventor: NUERK SIEGFRIED
IPC: D04B15/48
Filed: 1979-01-08
Abstract: Yarn metering drum for textile machinery has a device for preventing formation of a balloon as the yarn is withdrawn over-end from the drum consisting of a series of single, flexible bristles fixed by one end near the axis of the drum and extending radially outwards to project over the edge of the drum, bridging the annular gap between two flat discs through which the yarn is withdrawn. The outer end of the bristles is left free, allowing the bristles to bend sideways to permit the passage of the yarn; the distance between the gap and the fixing point of the bristles is at least twice the width of the gap. Force required to bend the bristles is very small, and friction between them and the yarn is negligible, hence increase in yarn tension is very small. The device does not contribute to yarn breakage, requires little maintenance, and has a very long life. It is effective irrespective of the dia. of the drum and its direction of rotation.

Title: Raising existing road bridge superstructure - involves staged elevation on retracting and extending hydraulic presses, and support insertion
Inventor: PAUL GUNDOLF
IPC: E01D22/00
Filed: 1979-06-22
Abstract: The superstructure of a road bridge, esp. across a river, supported on end bases and any intervening piers, is first raised by hydraulic presses and then lowered onto support elements thrust below the bridge bearings. The retracted presses are set on a correspondingly elevated base, and extended to raise the superstructure, which is then lowered onto further support elements at greater height, until the required level is attained. Bases and piers are heightened in stages, and bridges bearings are secured on them. Plates, of bridge width, are hinged to the superstructure ends, with their open ends sliding on the road tracks during raising and lowering. An existing bridge superstructure can be raised - as required because of higher water level or taller ship passage - without erecting a new one, and with min. road traffic interruption.

Title: Double pushbutton switch for vehicle seat heating - ensures only one switch stays in when both are pressed
Inventor: STRUHT HERMANN PETER
IPC: H01H13/68
Filed: 1979-08-28
Abstract: The switch housing (1) contains two spring loaded push switches (2) and (3), which when depressed connect the contacts (4), by a linkage, consisting of a locking cam (8) and a switch stop ratchet (9), contained in a journal (10) allowing it to move radially and axially. When the push-button (2) is pressed against its spring, the locking cam (8) moves downwards while the ratchet (9) moves against the force of the lever spring (11) until the bottom point of the button (2) is reached. After releasing the applied pressure, the button moves back slightly and the locking cam (8) latches into the niche (19) in the hook plate (16). This locks the push-button (2) in the 'ON' position, but if it is desired to return it to the 'OFF' position, this can be achieved by either pressing it again, or pushing the other button (3).
Patent DE-2941452-A1 (DE)
Inventor: BLUETHGEN BJOERN
IPC: H04B1/66
Filed: 1979-10-12
Abstract: A method for encoding analog signals for storage or transmission purposes, particularly for the digital recording of audio signals in studio devices, samples periodic values of the analog signals and converts the sampled values into pulse-code modulation code words. Successive pulse-code modulation code words are transformed by means of subtraction into pulse-code modulation difference code words and, together with additional auxiliary code elements, form a reference code word having a selected constant length. A reduction of the digital signal flow is achieved as a result of the reference code word, including the auxiliary code elements, being selected shorter than the maximum possible length of a pulse-code modulation difference code word. The generated pulse-code modulation difference code words are continuously monitored as to length, and upon the identification of a difference code word having an excess length, that is, greater than the reference code word, either the excess-length difference code word is abbreviated or is replaced by a pulse-code modulation code word of suitable length.
