Patent DE-2205902-A1 (DE)
Title: Heat pipe - dielectric pump returns condensed liquid
Inventor: REISS FRIEDRICH DIPL PHYS
IPC: F28D15/04
Filed: 1972-02-08
Abstract: The heat pipe comprises an evaporator at one end of the tube for the operation fluid, which passes in the vapour form to cooler parts of the tube where it condenses and an internal structure for the return of the condensate to the evaporator, whereby the internal structure is a dielectric pump, which returns the operating fluid of relative high dielectric constant low density and low electrical conductivity such as nitrobenzol, sulphur and liquid hydrogen by itself and by additional forces such as capillary forces. The dielectric pump consists of one or more pairs of opposed electrically insulated electrodes, creating by means of a direct current an electrical field, which is substantially transverse to the direction of the returning condensate flow. Such an arrangement is especially suitable for long pipes where the increase in condensate return, increases the overall heat transfer efficiency of the heat pipe.

Title: EITHER logic gate - has single gate for half adder to replace five gates which is connected with a discriminator
Inventor: KOCHANN RALF
IPC: H03K19/20
Filed: 1973-09-12
Abstract: Logic gates are used to make up parallel adders in computers and similar electronic counting devices. The addition of two digits gives a sum and a carry.

Title: Noise estimation for frequency multiplex communications - measures noise power in unoccupied channel wrt power of white noise over same band
Inventor: ALLEN EDGAR ROBERT
IPC: G01R29/26
Filed: 1974-07-24
Abstract: The noise estimator, is intended for frequency multiplex multi-channel communications links, and is carried out by measuring the traffic-to-noise ratio. An unoccupied channel in the link is disconnected and its noise power level is measured in a given band with respect to the noise power from white noise in this same band.

Title: Resistance seam welding, esp. of austenitic sheet - using electronic control circuit contg. Hall generator and Schmitt triggers
Inventor: DRECHSLER GUIDO
IPC: B23K11/25
Filed: 1974-08-16
Abstract: In a process for avoiding welding defects in resistance seam welding using alternating current (A.C.), the electrical work in each A.C. period causing a spot weld is measured using a multiplier feeding a voltage into an integrating circuit controlling a Schmitt trigger which uses high-speed switching relays to alter the phase angle in a phase shifting circuit so that a larger or smaller amt. of electrical energy is delivered in the next welding period according to the signal supplied via the multiplier. The multiplier is pref. a Hall multiplier, i.e. a Hall generator. Good welds are obtd., esp. on austenitic sheets, as the process allows for the varying electrical resistance at the junctions between electrodes and workpieces.

Title: Cast steel radiator for hot water heating - has sections with cross sections smaller than header cross sections
Inventor: LIEBY GUSTAV
IPC: F28D1/02
Filed: 1974-10-02
Abstract: The radiator has upper and lower headers joined by a series of perpendicular sections forming waterways between the headers. The headers have oval cross sections with the long axis perpendicular to the waterways and the waterways have circular cross sections with a diameter less than the long axis of the header section. At the top the waterways project beyond the header and terminate in screwed ends which are plugged after the radiator is cast. This arrangement makes it possible for the waterway cores to fit into recesses in the lower header core and to pass through holes in the upper header core which in turn makes it possible for the cores to be withdrawn in one piece and reused.

Title: Fastening method for leads on dielectric disc - disc is inserted in gap formed between ends of bent wireEE
Inventor: KOEHSEL HELMUT
IPC: H01R43/02
Filed: 1974-10-22
Abstract: The U-shaped fastening wire is mechanically pretensioned, and its free ends are bent to face each other. Free wire ends are flattened before bending wetted with a flux and tinned, then again wetted with flux and flattened. Wire ends so prepared lie flat on the inserted disc, and an h.f. field is then applied to the assembly. This procedure covers the electrode surfaces with a minimum of solder yet holds the connecting wires mechanically firm with the ceramic disc so that an equalizing of the capacity value is made easy. A precise positioning of the ceramic dielectric is made possible especially when this is of rectangular, as opposed to circular shape.
