Title: Structure of heavy-current cable for free suspension - uses centre steel cable as load carrier with peripheral conductor arrangement
IPC: H01B7/22
Filed: 1973-07-30
Abstract: The cable design uses a steel cable in the centre as weight carrier and for tensile strength. Insulated copper conductors are twisted around the outside of the PVC covered steel cable. A protective conductive sheath followed by an external cover completes the cable. For a fixed current load the required total copper cross-section area for the peripheral arranged conductors is less than that for a single conductive cable designed for the same load. The advantages obtained are less copper, smaller bending radius and cost reduction.

IPC: B43L13/20
Filed: 1973-08-23
Abstract: Curved ruler has a boundary corresponding to a quadratic function, containing the vertex of the curve, and is printed with axially parallel lines. Preferably data are given on the dimensional ratio at which beam support widths are to be applied, and/or on the available height of uniform loading. The ruler is printed on paper or foil.

The directrix is parallel to the support direction of the beam which is mounted and elastically stressed on both sides. The parameter of the parabola depends on the height of the loading and on the dimensional ratio of the beam support width.

Title: Liquefied gas pump discharge arrangement - using jet pump driven by partial evaporation of liquefied gas and with condensation during recycling
Inventor: ALADIEW IWAN TIMOFEEWITSCH
IPC: F04F5/24
Filed: 1973-08-25
Abstract: Liquefied gas is pumped away by excess press. produced by a jet pump, by revolving part of the liquefied gas at the outlet of the pump, evaporating it and feeding it to the pump inlet with condensation in the course of mixing with liquefied gas up to the removal point at the outlet of the pump. Preferably the starting period operation uses a part of the liquefied gas which is removed before the pump, increased in press., evaporated, and condensed in the course of mixing with the liquefied gas up to the point of removal, with transition to the stationary process. Pumping is effected solely by supply of heat, without mechanical means.
Patent DE-2343480-A1 (DE)
Title: Electrically controlled switchgear - is for acoustic travelling speed indication with generation of voltage at certain speeds
Inventor: GEB HEINRICH INGEBURG SCHILLMA
IPC: G01P3/487
Filed: 1973-08-29
Abstract: At certain speeds of rotation of the tachometer shaft, hence at certain travelling speeds of a motor vehicle, a certain electrical voltage is generated in the generator of the electrically controlled switchgear for the acoustic travelling speed indication. The voltage produced in the generator cuts in and out acoustic signals by way of transistor circuits at certain travelling speeds. In this process, the cut-in and cut-out points of the signal transmitters are adjustable independently of the voltage and can, therefore, be set to any travelling speeds.

Title: Spot-welding process and device - where electrode is fed downwards through holder during each reverse stroke
Inventor: DENGLER EMIL DIPL ING
IPC: B23K11/30
Filed: 1973-12-14
Abstract: An electrode with a constant cross-section is adjusted in a longitudinal direction w.r.t. the holder in which the electrode is mounted. The adjustment pref. occurs after each spot-weld and is controlled by the stroke of the holder. The pref. device uses an electrode with an external thread located in a stationary bush, the upper part of the electrode being fixed in a rotary component in the holder. During each reverse stroke of the holder, a lever and ratchet mechanism rotate the electrode by a small amt. so it travels down the stationary bush. An electrode with a constant dia. is used during a series of spot-welds, so that consistent welds are obtd.

Title: Electro hydraulic adjusting device - has drive motor, pump and servo piston with damping chambers in top and bottom end positions
Inventor: HENRICH KURT
IPC: F15B15/18
Filed: 1973-12-21
Abstract: Device has a motor, which drives a pump for the working fluid, which acts on a servo piston, which is equi-axially arranged with the drive motor and the pump in a cylindrical housing. Damping chambers are arranged in the top and bottom end positions to eliminate a hard stop of the servo piston.

Patent DE-2409180-A1 (DE)
Title: Electrolytic polishing of niobium parts - providing apertured plate between cathode and niobium part
Inventor: SCHMIDT OTTO
IPC: C25F3/26
Filed: 1974-02-26
Abstract: In the electrolytic polishing of Nb described in the Parent Specification, the Nb is the anode and the electrolyte is H2SO4, Hf and water and a d.c. potential is applied such that damped oscillations are produced. When the current oscillations have faded away the current is switched off until an oxide layer is formal on the Nb surface. The process is then repeated until the required extent of etching has taken place. in this patent the method is modified by providing between the niobium part to be polished, (the anode) and the cathode a perforated separating wall. The method is used for polishing more complex shapes than in the main patent such as long plates, cylindrical bodies and beaker shaped bodies e.g. superconducting hollow resonators for particle accelerators. The perforated plate prevents hydrogen generated at the cathode from reaching and spoling the niobium cathode surfaces.

Title: Cable jointing box for telephone installations - with sectionalised enplates carrying cable glands
Inventor: ALBRECHT CHRISTHART
IPC: H02G15/117
Filed: 1974-05-06
Abstract: A muff type cable jointing box has a body and end-plates which are sealed by means of gaskets. The end-plates are split into at least two pieces by jointing flanges which pass through one, and preferably all, the cable entries. Extensions or glands on the cable entries directed towards the inside of the muff have recesses to take sealing compound to seal the cable into the fland. The sectionalised plates are held together by clamping rings which fit round the extensions. These clamp rings are also split. The sectionalising of the end-plates and clamp rings allows ready assembly onto the cables without the need for threading, and also eliminates the need for production to very close tolerances.
