Patent DE-3007387-A1 (DE)
Title: Split yarn winder - has spindle group with drive controlled by yarn tension
Inventor: GUETTLER HERMANN ING GRAD
IPC: B65H51/005
Filed: 1980-02-27
Abstract: The spindles (14) are arranged as a spindle group (11), to wind the continuous fine yarns (13') split from the feed yarn(13). They are driven by a power unit, at variable speeds, with a speed adjuster (50) for the spindle group which is set by the output signal from a controller (49) according to the tension of the drawn feed yarn. Therefore the speed adjuster (50) also acts as a yarn tension control for the drawn split fine yarns (13'). The design ensures that the fine yarns split off from the feed yarn have a consistent quality along their whole length, and that the fine split yarns can be wound at high speeds.

Title: Hay making machine with retractable outer raking members - which are held in retracted position for travelling by springs acting on support rotor
Inventor: WEIDTMANN RAINER DIPL ING
IPC: A01D78/10
Filed: 1980-08-09
Abstract: The hay making machine has a line of raking members which rotate about a vertical axis. They are mounted on a beam so that the two outer raking members can be swung upwards vertically for travelling e.g. along roads so that the overall width is reduced. Each retractable raking member is connected by a system of arms to piston and cylinder at the centre, controlling its upwards swing. This operation is assisted by compression springs. In the retracted position, the arm carrying the raking member slopes inwards at an acute angle to the vertical for safety reasons. When pressure is cut off from the control piston, the arm is held in position by its spring so that it does not swing back again accidentally.

Title: Low loss power switching transistor circuit - has parallel faster FET which conducts during transitions
Inventor: MEISSEN WOLFGANG DIPL ING
IPC: H03K17/64
Filed: 1980-08-12
Abstract: Switching losses due to the relatively slow switching speeds of bi-polar power transistors are eliminated in this circuit by a parallel, faster FET which conducts during the brief transition periods only, resulting in high efficiency even at high frequencies. A bi-polar power transistor (2) has a field-effect transistor (6) connected in parallel which conducts during the on- and off transitions of the slower power transistor (2) and actually turns off the power transistor during these periods. The base inputs of the two transistors are switched simultaneously.

Title: Heat exchanger for geothermal heating system - has tubes with pointed tips for driving into ground with increased dia. at tube transition
Inventor: HAMPE ANDREAS DR ING
IPC: E02D7/08
Filed: 1980-08-22
Abstract: The heat exchanger consists of tubes (1) driven into the soil like piles. The end of the tube (1) is fitted with a conical tip (2) with a maximum diameter (D) at the transition point, which is about ten percent greater than the tube diameter (d). When the tube is driven into the ground a hole of the max. diameter (D) is initially formed and provides clearance for the tube. It has been found that there is a relaxation of the ground which causes the diameter of the hole to shrink gradually in a way meeting an exponential law, until after about 24 hours the hole closes around the outer surface of the tube. The conical tip may be pressed or screwed into the tube. The diameter of the tube is 25 mm making it particularly suitable for small installations.
Patent DE-3035848-A1 (DE)
Title: DC generator impedance matching to accumulator battery - measures repeatedly output voltage and current of control circuit and adjust chopper periodic ratio accordingly
Inventor: BLASER REINHARD DIPL ING DR IN
IPC: H02M3/335
Filed: 1980-09-23
Abstract: The impedance of the accumulator is continuously rising during charging. The d.c. generator voltage is converted by a control circuit into a voltage required for charging, using a chopper whose a.c. voltage is converted by a transformer and supplied to a rectifier. The output voltage and current of the control circuit are measured and their respective values multiplied. The measuring current, the multiplication product, and pref. the measured voltage are stored. Then the periodic ratio of the chopper is slightly changed, and the control circuit output current measured again. After computing the product of this output current value with the available stored voltage, this product is compared with the previous one. The periodic chopper ratio is changed in the same or opposite direction according to the comparison of the two products. The process is repeated until a maximum product of the last measured current with the stored voltage is obtained.

Title: Method and device for dissolving particulate nuclear fuels out of high-temperature fuel elements
Inventor: VIETZKE HORST DIPL CHEM DR
IPC: G21C19/46
Filed: 1981-01-31
Abstract: Methods and devices which can achieve high dissolution rates are required to use flowing nitric acid to dissolve particulate nuclear fuels, in particular, out of spent HTR fuel elements contained in a dissolving basket along with their mechanically crushed, hemispherical silicon carbide claddings after the carbon has been removed. For this purpose, the flow of the acid is chosen in such a way that the silicon carbide claddings are rinsed out of the dissolving basket but the heavy cores are left behind. This is achieved if the cross-section of the outlet connecting pipe (9) underneath the dissolving basket (4) is made at least 1.5 times as large as the overflow connecting pipe (8) used as connection to the shallow tank (2) serving as acid reservoir. <IMAGE>

Title: Oil absorbent for water purification
Inventor: VAHLENSIECK HANS-JOACHIM DIPL
IPC: B01D17/022
Filed: 1981-04-02
Abstract: The present invention relates to a novel absorbent for oils and fats. This novel absorbent, as are the known agents, is porous and has a large surface area. However, it must also fulfil the following conditions: its overall density must be below 1 and the proportion of open pores must be at least 20%. Furthermore, the agent must be impregnated with alkylsilanes and/or phenylsilanes and/or organofunctional silanes. Because of this treatment and the claimed physical properties, the absorbent floats in the unladen state on the surface of water and sinks beneath it after it is loaded with oils or fats. The novel absorbent is particularly suitable for cleaning fat- or oil-containing waste waters in the metal industry and engineering industry.

Patent DE-3124686-A1 (DE)
Title: Façade-cladding system for the exterior façade of buildings
Inventor: ROSCHILD ERNST ING GRAD
IPC: E04F13/04
Filed: 1981-06-24
Abstract: When using façade-insulating panels in the form of plaster-carrier panels for the heat insulation on the exterior side of the façade, the achievable insulating thickness is restricted in that the insulating material has only a restricted mechanical load-bearing capacity and, from a thickness of not more than 10 cm, can no longer support the exterior plaster in a sufficiently stable manner. By using a load-bearing structure, for example comprising H-beams, for spacing purposes, the invention provides a multiplicity of retaining surfaces which are at a distance from the exterior surface of the backing and on which conventional plaster-carrier panels of restricted thickness can be fastened, for example via bonding mortar and additional mechanical fastening means. The interspace between the retaining surfaces and the exterior surface of the backing is then available for fitting a further heat-insulating material which need not be loaded mechanically and is loaded only insofar as this is expedient in the individual case for additionally securing the plaster-carrier panels. By a special design of the heat-insulating material, for example of compressed mineral-fibre panels with fibres lying transversely with respect to the backing, the heat-insulating material can, however, also assume a securing function for the plaster-carrier panels, and the retaining surfaces can be arranged at a greater distance from one another. When using heat-insulating material in a thickness which is double that of the plaster-carrier panels, then insulating thicknesses of more than 30 cm altogether can be achieved over the exterior surface of the backing.
