Patent DE-2437092-A1 (DE)
Title: Cable tray construction using C-section material - for both longitudinal supports and lateral spacers uses standard sections with slots in spacers
Inventor: BENTHIN JOHANNES
IPC: F16L3/26
Filed: 1974-08-01
Abstract: The construction uses the same flattened C-section material for all parts. In the longitudinal support members (1, 2) the open side is towards the outside of the tray, whilst the lateral spacers (3) have their open side towards the bottom. Cables entering or leaving the tray thus pass over rounded surfaces and damage to insulation is prevented. The lateral members are provided with cut outs (4) to take ties or clamps for holding the cable bundles in place. The support members (5) may also be of C-section with their open sides towards the outside. The profile material can readily be formed to the required shape during installation and the system lends itself to shipboard wiring.

Title: Multiple stage catalytic reforming of hydrocarbons - using fixed bed radial flow reactors in series with moving bed downflow reactor
Inventor: STONE RICHARD DAVID
IPC: C10G35/12
Filed: 1974-08-07
Abstract: In the multiple-stage catalytic reforming of a hydrocarbon feed stream, the feed stream is fed initially to a first stage consisting of a number of fixed-bed, radial-flow catalytic reaction zones arranged in series and the effluent from the last of these zones passes to a second-stage consisting of a downflow reaction zone contg. a bed of catalyst particles which migrate downwards under gravity and which are removed at the bottom of the reaction zone while fresh or regenerated catalyst particles are supplied to the top of that zone. The process is applicable to various vapour phase hydrogenating and hydrorefining operations, but particularly to the reforming ofnaptha fractions for improving the motor fuel anti-knock characteristics thereof.

Title: Frequency doubler for AC circuit - employs triacs to change supply polarity every half cycle at voltage maximum
Inventor: VACEK JAN DIPL ING
IPC: H02M5/27
Filed: 1975-06-27
Abstract: A frequency doubler does not produce use saturable cores and their windings, by switching the supply voltage to the load at each voltage peak from one polarity to the other. Thus in alternate half cycles the voltage applied to the load changes abruptly from maximum to minimum, whilst in the other half cycle it changes sinusoidally from minimum to maximum. The switching may be done with four triacs. Two are connected directly between input and output, whilst the other two are connected diagonally for the polarity reversal to the load. Thus the frequency at the output terminals is twice that at the input. A solid state triggering circuit (top part of diagram) forms the require pulses using the zero cross-over points of a phase advanced voltage in synchronism with the main supply.

Title: Reduction in leaky cable junction discontinuity - uses reflector for leakage radiation one half wave length from cable to reduce phase shift at junction
Inventor: EVANS RONALD HAROLD
IPC: H04B5/00
Filed: 1975-10-11
Abstract: The characteristics of leaky coaxial cable systems at cable to cable or cable-repeater-cable junctions are improved by reducing the jump in level and the phase shift at the junction. At each junction (2) between two cable sections (1) a reflector (3) is introduced. The distance between one end of the reflector and the part of the cable opposite it may be equal to a half wave and the distance of the other end of the reflector less than a quarter wave. Alternatively with a constant distance between reflector and cable the reflection coefficients of the individual parts of the reflector are so contrived that the directly radiated wave from the reflector is increasingly amplified with increasing distance from the coupling.
