Patent DE-3247483-A1 (DE)
Title: Device for utilising the exhaust heat to quickly thaw frozen car windows
Inventor: EMEKTAR CENGIZ
IPC: B60S1/54
Filed: 1982-12-22
Abstract: Device for utilising the exhaust heat to quickly thaw frozen car windows. Said device is composed of a sleeve 4 which is guided directly on the exhaust manifold around the exhaust pipe 3 and has a larger diameter than the exhaust pipe, enclosing the latter over a certain length. The sleeve 4 has a branch 6 to which is connected a metal hose 7 which leads to the blower of the car. With the engine running and the blower switched on, hot air which forms in the sleeve 4 is sucked in via the hose line 7 and then, in the region of the windscreen, passes through the slots 10 provided onto the windscreen and into the car interior and very quickly makes the windows ice-free. When the blower is switched on, slides provided close the slots 9 for the fresh-air feed so that only hot air is sucked in via the hose line. <IMAGE>

Title: Method and arrangement for measuring radiation-dependent characteristics of a body
Inventor: HERZOG HANS-JOEST DIPL PHYS
IPC: G01N23/06
Filed: 1983-01-21
Abstract: Particularly in industrial X-ray absorption measurements, e.g. in the monitoring of preforms for glass fibre optical waveguides, there is a need for a cost-effective and quick measuring method which enables a high spatial resolution. According to the invention, the adjusting process is substantially shortened by using at least one slit diaphragm, preferably two crossed slit diaphragms, to mask out a measuring beam.

Title: Structure with an arched construction
Inventor: SCHNEIDER HEINRICH
IPC: E21D11/08
Filed: 1983-04-06
Abstract: The invention relates to a structure with an arched construction, such as a bridge or a tunnel. The intention is to make it possible to erect such structures economically and without great constructional outlay on the site. For this purpose, the arch construction is composed of precast concrete components in which cavities have been formed during manufacture by means of displacers consisting of latticework covered with foil. Some of the cavities are filled with in situ concrete. In particular, parts of vertically or horizontally adjacent cavities are filled all the way through with in situ concrete and thereby connected. Reinforcements for the in situ concrete are introduced as parts of the displacers.

Title: Dismantling safeguard for a filter unit
Inventor: WARIAS DIETER
IPC: B01D36/00
Filed: 1983-04-12
Abstract: In order, in a filter unit, to prevent the screw securing the filter housing and filter cover from being undone, so long as the filter unit is under pressure, an operating pressure-dependent safeguard means is proposed. The access to the hexagonal socket (7) of the securing screw (3) is blocked by means of a pin (12) in such a manner, that above a certain pressure in the interior (16) of the filter unit, applying an Allen key to undo the securing screw (3) is prevented. <IMAGE>

Title: Rail wheel with rubber suspension
Inventor: RITTINGHAUS ROLF DIPL ING
IPC: B60B17/00
Filed: 1983-04-28
Abstract: The rail wheel with rubber suspension consists of a wheel tyre, the rubber elements, a rim component and a wheel disc element. The rubber elements are arranged between the wheel tyre and the rim component. The rim component consists of an annular element which has two shoulders in the direction of the wheel tyre and can be pushed onto the wheel disc element. The rim component has, in the direction of the wheel hub, a circumferential stop with bores for clamping bolts which are turned into the wheel disc element. The rim component is pushed onto the wheel disc element from one end side until it comes to rest against the circumferential stop. This constructional design permits wheel tyres and/or rubber elements to be changed without the assembly consisting of wheel tyre, rubber element and rim component being mounted on, or removed from, a wheel disc element. This constructional design also permits rail wheels which have rubber suspension and consist of wheel tyre, rubber elements and wheel disc to be converted in such a way that an assembly which consists of wheel tyre, rubber elements and a rim component can be mounted on a wheel disc element, the wheel tyres having the original dimensions.

Patent DE-3323202-A1 (DE)
Title: Melt spinning and drawing process for producing polypropylene filaments
Inventor: HENSEN FRIEDHELM PROF DR ING
IPC: D02J1/22
Filed: 1983-06-28
Abstract: A melt spinning and drawing process for producing polypropylene filaments is proposed by means of which, using polypropylene of conventional spinning quality grades, textile filaments and fibres are obtained of unusually high breaking strength of more than 5 cN/dtex. It is decisive in this case for the process conditions that crystallisation of the spun polymers as a result of abrupt quenching in the cooling zone beneath the spinneret is prevented as far as is possible. Crystallisation is induced and promoted after drawing. For this purpose, it is necessary that following the longitudinal orientation of the molecules, a sufficiently long residence time for the aftercrystallisation is available, in which the filaments are held at a temperature at which there is a high crystallisation rate.

Patent DE-3333836-A1 (DE)
Title: Process for the production of dyed fur pelts
Inventor: MANDT JUERGEN DIPL CHEM DR
IPC: D06P5/22
Filed: 1983-09-20
Abstract: The invention starts out from a process for the production of dyed fur pelts with silvery ends using oxidation dyestuffs in the liquor. In order to be able to imitate silvery ends in less valuable pelts, on the basis of the invention the fur pelts are treated with polyvalent metal salts and then, before dyeing in the liquor, the ends are treated with a solution which excludes formation of dyestuff on the ends. To do this, the ends can be treated with a solution which converts the metal ions into stable complexes.

IPC: D21F1/00
Filed: 1983-10-27
Abstract: A method in the dry end of a papermachine is described, which serves for stabilising the running of the paper web. In the method, the paper web (W) is transported, borne by a cloth such as, for example, a drying screen (12), from one row of drying cylinders (10, 11) to another in such a way that the web (W) is located between the drying screen and the cylinder surface on one of the rows of drying cylinders and, on the other row of drying cylinders, runs on the outer surface of the drying screen. In the method, blowing devices are used, by means of which the running of the web in the common passes, extending between the rows of drying cylinders, of web and drying screen (12) is stabilised. In the regions of the two edges (W') of the web (W), air jets (F1) are blown out on the side of the drying screen (12) in the direction opposite to the running of the drying screen and of the web, and these are directed in the region of the wedge-shaped space (K-), formed between the drying cylinder (10) and the web (W) borne by the drying screen (12), against the drying screen (12) at least up to the base line (B) of the said wedge-shaped space (K-). These air jets (F1), which are blown out through a plurality of successive nozzle slots, eject air (F2) and the reduced pressure prevailing in this region on the opposite side of the web (W) in the wedge-shaped space (K-) ... for the purpose of adhesion of the web (W) and its edges (W') to the transport screen ...

IPC: H05B41/298
Filed: 1984-08-13
Abstract: In the case of a transistorised tuned-circuit invertor in a half-bridge circuit, no-mode operation is made possible in that, on the one hand, the load is connected in series with the tuned circuit which determines the operating frequency of the loaded invertor and this tuned circuit is in consequence interrupted in no-mode operation. On the other hand, the drive level of the transistors in no-mode operation is ensured with the aid of the additional winding on a control transformer. This additional winding is connected in series with a high-resistance current-limiting resistor, as a result of which stable no-mode operation remains ensured.
