Title: Conductive wire covering - with elastomer or plastomer by microwave energy in extruder head for vulcanisation or crosslinking
Inventor: FOCHT HARRY
IPC: B29C48/06
Filed: 1979-06-29
Abstract: Strands of electrically conductive material are coated with an elastomer or a plastomer in an extruder with a screw and a nozzle head. Directly in or ahead of the latter, microwave energy is injected into the strand over a very short distance and caused to travel in the strand in the direction of motion. This produces the heat for the vulcanisation of an elastomer or the crosslinking of a plastomer. The action of the microwaves continues downstream of the nozzle which is specially advantageous when a second coating is to be applied through a second extruder. The effect is a very uniform vulcanisation or crosslinking.

Title: Cyclic ether prodn. by dehydrating a glycol - in liq. suspension of calcined alumina catalyst
Inventor: MUELLER HERBERT
IPC: B01J21/04
Filed: 1979-07-25
Abstract: Prodn. of cyclic ethers (I) comprises liq. phase dehydration of alpha, omega-diols (II) in presence of alumina suspended in the reaction mixt. The alumina is prepd. by pptn. of an alkali aluminate soln. with acid, then heating at 300-1000 deg. C. The method is used to prepare ethers (I) (A is 4-8C alkylene, opt. interrupted by heteroatoms) e.g. 1,4-dioxan from diethylene glycol or 2,5-dihydrofuran from cis-buten-2- diol-1,4. The catalyst gives almost quantitative yields and works effectively even with relatively impure diols. Catalyst consumption is low; it is not corrosive so relatively inexpensive materials can be used for the reactors, and the reaction rate is high e.g. at 210 deg. C 1-3 pts. THF per hr. per pt. catalyst.
Patent DE-2936757-A1 (DE)
Title: Water drain for parked windscreen wiper - has slotted support at bottom of stroke
Inventor: PFISTERER DIETER
IPC: B60S1/04
Filed: 1979-09-12
Abstract: The water drain for a parked windscreen wiper blade has holes under the blade to allow the slipstream to blow the trapped water upwards and clear of the windscreen. The holes are either moulded into the windscreen or are formed by a slotted guide applied to the glass to allow the blade to ride up. The drain ensures that the otherwise trapped water does not follow the blade and cause poor visibility at the trailing edge. It also prevents trapped water from picking up dust and straining the windscreen.

Title: DC amplifier with voltage input and current output - has two operational amplifier stages with output transistor in each stage
Inventor: BAUR GEB KALHOEFER
IPC: H03F3/68
Filed: 1979-11-27
Abstract: The proposed circuit facilitates changing the operating point, e.g. the gain, without the necessity for trimming and balancing the complete amplifier. Input and output are referred to zero volts. The amplifier is divided into two stages, each containing an operational amplifier. The stages operate with opposite polarity. The first stage output is connected to the high impedance input of a transistor, typically a FET, connected across the power supply. This transistor applies a voltage proportional to the input voltage to the second stage. The second stage output is similarly loaded with a transistor. The output into the load is a current proportional to the input voltage which is independent of the load resistance over a wide range.

Title: Variable appearance doubly slatted venetian blind - has two ladder cords and changeover cord permitting instant change of slats
Inventor: UETAKE KINZO
IPC: E06B9/303
Filed: 1980-06-13
Abstract: A ladder cord hanging down from a tubular unit, with slats hanging on it, together with a tilting device and raising cord, are incorporated in a venetian blind. Slats (7,8) are alternately arranged in two parallel groups independently hung on two ladder cords (9,10). The top of one cord is attached to the periphery of the tubular unit (1), and the top of the other is drawn into this unit through a hole (11) on its periphery, and then linked to an end of a cord (14) for changeover. This cord passes through the other end (2) of the tubular unit, and extends downwards from the second bearing (4), enabling the blind to change from a sheet composed of one set of slats to one composed of the other, by a single cord operation, without changing the inclination of the slats.

Title: Storable electrotype, esp. for mfg. video and audio disks - where original positive disk is protected against corrosion by nickel coating, and is used to make press dies
Inventor: BECKER JOHANN
IPC: C25D1/10
Filed: 1980-09-22
Abstract: A master recording, i.e. a cut foil, is used to make an original positive disk(P). Disk(P) is used to make dies for pressing disks on which high density data are stored. The data side of disk(P) is cleaned and passivated, and coated with a thin nickel layer(NS) with low internal stress. Layer(NS) extends over the edge of disk(P) and provides protection against corrosion during storage of the disk(P). Layer(NS) is pref. 3-10 microns thick; to make a die it is activated and thickened except on its edge. The edge is then cut off and the thick layer is detached from the disk(P) and used as a press die. Disk(P) can be used for the repeated intermittent mfr. of press dies. After each use, a new layer(NS) is applied to protect disk(P) until it is required at some future date.

Title: Mechanical-electrical transducer
Inventor: BALCKE GERHARD ING GRAD
IPC: G01L9/14
Filed: 1981-01-10
Abstract: A mechanical-electrical transducer is specified, having a pressure vessel for the measurement of pressure, flow speed, height or rate of climb/descent, in which at least one magnet and an electrical structural element which is sensitive to a magnetic field are arranged, whose position relative to one another can be varied as a function of an expansion of the pressure vessel. In this case, the characteristic of the structural element is set depending on the variable to be measured, such that the transducer has a linear characteristic overall. For this purpose, a field plate having a parabolic characteristic is used to measure a gas pressure, a Hall integrated circuit with a linear characteristic being used to measure the flow speed of a gas or a height. A differential stage is used in addition, to measure the rate of climb/descent. <IMAGE>

Inventor: MARWITZ HEINRICH DIPL CHEM DR
IPC: D06M101/16
Filed: 1981-02-10
Abstract: Organic fibers are impregnated with an aqueous emulsion comprising (1) an organopolysiloxane containing diorganosiloxane units in which both organic radicals are monovalent hydrocarbon radicals, and further contains at least two monovalent SiC-bonded organic radicals with a basic nitrogen atom per molecule in which the SiC-bonded organic radicals with a basic nitrogen are present in monoorganosiloxane units, (2) an organopolysiloxane having at least 3 Si-bonded hydrogen atoms per molecule, (3) a catalyst for the condensation of Si-bonded condensable groups (4) emulsifiers, and (5) a diorganopolysiloxane containing an Si-bonded hydroxyl group in each of its terminal units and whose radicals are free of the basic nitrogen atom. If it is desired to impart hydrophobic properties to the impregnated organic fibers, then it is essential that (6) a trimethylsiloxy end-blocked diorganopolysiloxane be added to the aqueous emulsion. Moreover, as the amount of trimethylsiloxy end-blocked diorganopolysiloxane (6) is increased in the emulsion, the hydrophobic properties of the impregnated fibers increases.
