Patent DE-2352194-A1 (DE)
Title: Testing method for line repeaters - involves exciting them one-by-one, irrespective of direction of their insertion
Inventor: SCHEFFLER HARTMUT
IPC: H04B17/40
Filed: 1973-10-18
Abstract: Each line repeater has an amplifier for each transmission direction, connected to the incoming or outgoing line by a transformer, whose line side windings has a centre tapping connected through a diode to that of the other transformer; line repeaters are supplied with d.c. over the phantom circuit from at least one supply end station; a control signal transmitted over the phantom circuit from the supervising station closes a test loop between the two amplifiers, so that the test signal returns through the other amplifier and line; this returned signal is evaluated, and the result signals the repeater operational state. The control signal is a brief interruption of the supply current.
Patent DE-2355601-A1 (DE)
Title: R-C network timing circuit - may store input signal for predetermined period and transmit it to output either in stretched or shortened form
Inventor: STEIN PETER
IPC: G04F10/10
Filed: 1973-11-07
Abstract: A control circuit transmits an incoming signal from a relay to an R-C circuit charged to a voltage dependent upon input signal duration. An externally controlled relay is operated after a predetermined interval to charge a second parallel R-C circuit. When the charging voltage reaches the same level in both R-C circuits a comparator generates an output via a load voltage limiter and a control circuit to operate a relay. The transmitted output signal is a delayed form of the input signal and is either stretched or shortened by the bias voltage determined by a control circuit. Repeatability is ensured by limiting operation of the R-C circuits to the near linear range.

Title: Emergency brake for car - with rubber covered brake pad pressed onto road by spring when released
Inventor: FICKENSCHER HANS
IPC: B60T1/14
Filed: 1974-02-06
Abstract: A rubber covered brake pad is provided with an inclined shaft which is positioned in an inclined tube under the car.

Title: Railway rolling stock wheel conical tread profile - has narrow cylindrical section for contacting wheel of diameter measuring system
Inventor: DOMBROWSKI THEODOR DIPL ING
IPC: B60B17/00
Filed: 1974-04-01
Abstract: The rolling stock wheel tyre has a conical profile before it joins the wheel flange, which has a short cylindrical section formed by turning. The cylindrical section is used for making positive parallel contact with the rim of the friction wheel used for accurate measuring of the wheel. The conical tread surface of the wheel has a slope in relation to the cylindrical section which is machined on reconditioning a wheel or on making a new wheel, by using a modified copy turning template. The width of the cylindrical part is so narrow that it does not affect the running characteristics, and is machined within the tolerances of the wheel tyre profile.

Title: T.V. signals scrambling, encoding and decoding - using sync.-signal modulation adjusted for psychological discomfort to viewer
Inventor: BLONDER ISAAC S
IPC: H04N7/16
Filed: 1974-04-01
Abstract: Method of scrambling, encoding and decoding television signals that contain horizontal and vertical synchronizing signals comprises picture-scrambling the television signals by modulating at least one of the horizontal and vertical synchronizing signals to produce, repetitively, normal-level successive synchronizing signals followed by such synchronizing signals attenuated and thus depressed to substantially the blanking level, but without affecting and altering the video signal information. The rate of such repetitive synchronizing-signal modulation is adjusted to a value that produces psychological discomfort to a viewer of the resulting shifting television picture on a normal receiver, encoding the aural signal information to render the same unintelligible at a normal receiver; transmitting the picture-scrambled and aural-encoded television signals and receiving the same; decoding the aural signal information to recover the same; and reversely attenuating and amplify the depressed-level synchronizing signals to restore the same to normal level and thus stop the repetitive television picture shifting and without change in picture reception quality over that obtained in unscrambled transmission and reception.

Title: Support for electromagnetic scanning pickup - used for rotational speed measurement of, e.g. gas turbines
Inventor: PASCHEN HEINZ
IPC: G01P3/488
Filed: 1974-05-02
Abstract: The electromagnetic scanning pick-up made to standard dimensions, is held by an adjustment nut in a support at a certain distance from a gear on the machine shaft, transmitting the measurement pulses by means of its teeth. The adjustment nut is secured against rotation with respect to the support by a hardenable plastic, so that the pick-up cannot be lifted from its support. The invention allows the fitting and exchange of pick-ups within the necessary very fine tolerances without the necessity of making advance measurements except in the case of a first fitting. The tolerance held is namely a distancing of the gear from the pick-up of from 0.24 mm. plus or minus 0.06 mm.

Title: Internal machine components inter-alignment process - designed for textiles and spinning machines internal components setting
Inventor: ZELLER RUDOLF
IPC: G01B11/27
Filed: 1974-08-23
Abstract: To assist in precise setting-up of internal textile fabricating machine components, not viewable from the outside, to each other or to a machine wall reference, an endoscope is let into a machine cavity. This sets up a directed light beam through an objective lens system. A directed part of the endoscope projects into the textile thread channel. This arrangement enables the components in the cavity to be observed directly and to align them exactly. Glass thread sensors can be used if crooked pathways are to be negotiated. In most cases the normally provided inlet and outlet openings are sufficient to complete the process.

Title: Aqueous processing agent for cellulosic textile materials - for non-crease, wash and wear finishes, without discolouration
Inventor: DEMARCO JOHN GREGORY
IPC: D06M101/02
Filed: 1975-01-07
Abstract: The aq. textile processing agent of Parent Patent contg. 1,3-dimethylol-4,5-dihydroxy-2-imidazolidinone, Zn nitrate as catalyst, and sequestering additives, for imparting a non-crease, non-iron finish to undyed textile materials contg. cellulose, without yellowing or singeing when hot pressed, is improved by replacing the Zn nitrate. The zinc salt is replaced as the catalyst by a Mg or Al salt, e.g. MgCl2 and/or AlCl3. The sequestering agent can be added from an aq. soln., simultaneously, before or after the imidazolidinone and the catalyst. Replacement of the Zn (which is toxic for sewage treatment bacteria) avoids need for purification of the effluent.

Title: Multiple pin plug connector - has slotted knob for aiding withdrawal and guarding cable against bending
Inventor: HALBACH SEBULON
IPC: H01R13/633
Filed: 1975-02-22
Abstract: The plug connector is made of an elastic synthetic material, is moulded onto the end of the cable, and normally is of multi-pin form. The connector comprises a housing (2) holding the connecting pins (3, 4) which extends axially to form a flattened knob (6). This serves to give a better grip when inserting or withdrawing the plug. This knob has several indentations (11, 12) in its flattened sides (9, 10) which penetrates through to the cable. The mould forming them may thus be used to locate the cable during the forming of the connector body. The stiffening imparted by the knob also serves to protect the cable against inadvertent bending when manipulating the plug.
