Title: Removing arsenic, antimony and bismuth from electrolytes - in refining non-ferrous metals, by adsorption on supported chemisorbent
Inventor: SCHULZE REINHOLD DR
IPC: B01D15/08
Filed: 1974-05-13
Abstract: According to the parent patent, in electrolytic refining of non-ferrous metals, eps. Cu, or in purification of electrolyte solns. with As, Sb and/or Bi is prevented by contacting the soln. with a chemisorption agent of large surface. In this pacification the chemisorption agent is applied to a flat substrate which has been bonded into compact units, and is protected before contact with adjacent substrates. The electrolyte soln. can be passed at a higher rate through the adsorber(s). The soln. can be completely removed from the adsorber; no mixing with regenerating solns. occurs. The adsorber can be aerated without air remaining after the liquids have been changed.

There is an axial hollow chamber in the roller that is open to the outer cover and can be connected to the low pressure source. There are a number of boreholes running from the hollow chamber to the outer cover. The boreholes are filled with a porous material. The roller can be made from porous material such as sintered metal. There is a suction connection point near the end face of the roller. It has a back pressure valve open to atmosphere.
Patent DE-2435308-A1 (DE)
Title: Electrode control for vehicle washers - with connecting via light switch to control lamp cleaning
Inventor: BOETZ JAKOB
IPC: B60S1/60
Filed: 1974-07-23
Abstract: The electronic control has a central timing control which maintains the wiping action on the windscreen for a set time interval after the washer pump is switched off. This ensures adequate removal of washing fluid. If the headlamps are switched on while the washers are switched off, then an additional timing sequence is included. In this the washer control is switched to the headlamps for a set period, followed by a set period of headlamp wiping. The windscreen wiping period remains unaltered. Operating the washer control at night thus ensures that the lamps are periodically cleaned as well.

Title: Hair dyeing compsns. for oxidation dyeing - contg. diamino pyrimidine derivs. as developers and conventional coupling agents
Inventor: KUBERSKY HANS PETER DIPL CHEM
IPC: A61Q5/10
Filed: 1975-05-24
Abstract: Hair-dyeing compsns. for oxidation-dyeing are improved in that they contain as developers diamino-pyrimidine derivs. having one of the following formulae: (in which R1-4 independently denote H, 1-4C alkyls, 1-4C hydroxyalkyls, opt. substd. phenyl or aralkyl; R1 and R2 can form with N a 5-6 membered ring which may contain an additional N atom or O atom; X is O or S). They are combined (opt. in the form of salts with inorganic or organic acids) in approx. equimolar ratio with conventional coupling agents, and the mixt. is incorporated into creams, emulsions, soln. or gels. in an amt. of 0.2-5 wt. %. They can be combined with direct dyes. These cpds. are compatible with the skin. In combination with conventional coupling agents (e.g. alpha-naphthol, o- or m-cresol, 2,6-dimethylphenol, etc), they produce very intensive colouration with good fastness. These cpds. are readily soluble in water, have good storage stability and are nontoxic. They can be easily removed with a reducing agent.

Title: Deep sea pressure resistant pipeline - has resilient circular casing with flexible cushioning filler surrounding conduit
Inventor: DRUDE BURKHARD CARL
IPC: F16L11/22
Filed: 1975-06-07
Abstract: The pressure resistant piping is used for liquid or gas transport under seawater at great depths. Hauling ropes or cables are connected with one or more hollow channels and embedded in flexible material. The pipe itself is made of impervious circular cross-section tube, and the inner flexible cushioning material is semicircular in cross-section, with curved edges. The tube is itself flexible and under maximum pressure it collapses resiliently around the conduit, but the fluid transport is unaffected due to the cushioning filler and the restoring force in the piping with two or three or more cables, the flexible filler material is arranged symmetrically with the cables as far from each other as possible to prevent crushing.

A Third resistance (R2) is connected between collector and base and a series resistor (R3) is coupled to the constant supply (UE). The resistors are so chosen to maintain the load voltage drop in a specified range.
Patent DE-2539355-A1 (DE)
Title: Glass melting furnace heated by several energy sources - using overhead fuel burners and deep refining zone contg. heater electrodes
Inventor: SORG HELMUT DIPL ING
IPC: C03B5/225
Filed: 1975-09-04
Abstract: Glass is melted by feeding a layer of the glass batch onto a molten bath of glass provided with overhead heating. Molten glass is removed from the bath via a bottom channel. The novelty is that after melting, the glass flows in a downward path, and is also heated in a horizontal zone by electric current, the glass then flows into a homogenizing zone and into the bottom outlet channel. The glass pref. flows horizontally into the zone above the heating electrodes, which are designed so the glass sinks uniformly in the refining zone. The pref. furnace uses a horizontal melting zone with a sill leading to a refining zone twice as deep as the melting zone and contg. heating electrodes which may also be used in the melting zone. The furnace is simple, rapid and economic to make and can be heated by gas and/or oil and/or electricity so that the amt. of each fuel can be adjusted according to their cost. The furnace produces molten glass of high quality.

Title: Function control circuit for car electric system - with current reduction detecting single chip operational amplifiers and LED indicators
Inventor: WEMHOENER JUERGEN
IPC: B60Q11/00
Filed: 1975-10-31
Abstract: The fuses of the car lighting circuit are coupled to a voltage monitoring circuit in which the failure of any lamp is detected by a current sensitive detector. This uses operational amplifiers, with each amplifier tuned to operate on a set current drop, or input voltage drop, corresponding to the particular lamp. The operational amplifier activates the corresponding LED to indicate to the driver which lamp has failed. The system can use several lamps on a single chip, and can operate on a single fuse for the whole lighting circuit, thus reducing the complexity of the control circuit.
