Title: Display for postal code on envelopes - has required numbers indicated by encircling preprinted numbers
Inventor: BERTRAM HEINRICH DR
IPC: G09F3/00
Filed: 1976-02-02
Abstract: Postal codes are used in the automatic sorting of letters. The difficulty of reading bad handwriting causes loss of time and also results in frequent mistakes. This problem can be overcome by pre-printing four columns of numbers from 0 to 9 on the envelope or address label. The sender of the letter then encircles one number in each column in order to indicate the required postal code. The four columns of numbers can be printed on small labels which need be no larger than a postage stamp, or special postage stamps could be used which include the four columns of numbers or in lines around the edges of the stamp.

Title: Expanded metal grids used as lead accumulator plates - where stiff metal or plastic substrate is clad with lead-antimony alloy
Inventor: LEPPER JUERGEN DIPL PHYS DR RE
IPC: H01M4/68
Filed: 1977-05-13
Abstract: The grid is made from a carrier substrate which is resistant to corrosion and bending; and the substrate is coated on one or both sides with a rolled sheet or strip of a Pb-Sb alloy contg. 0.5-3.5% Sb. The composite metal is then made into expanded metal in a conventional manner. Substrate is pref. a sheet or strip of Pb contg. 0.05-0.1% Ca, the Pb-Sb sheets being applied by roll cladding. Alternatively, the substrate may be a plastic resistant to H2SO4. The use of Pb-Sb alloys for grids permits the mfr. of accumulators which are free from maintenance, but this alloy lacks stiffness. The invention uses a stiff, carrier substrate of Pb-Ca or plastic to provide grids with adequate rigidity.

Title: Stencil with letters mounted on rotatable disc - uses ball pen to transfer letters from stencil to paper
Inventor: JANZ WERNER
IPC: B44C1/16
Filed: 1977-08-04
Abstract: Stencil for transferring individual letters of the alphabet to a sheet of paper consists of a rectangular sheet of material (1) with a central boss made of plastic which supports a rotatable disc(2). The rotatable disc carries two concentric circular rows of letters(6) of the alphabet. By rotating the disc any one of these letters can be aligned with a slot(11) cut in the sheet(1). The stencil is placed over a sheet of paper which is aligned with the lines(12) at the edge of the support sheet(1). A ball pen is pressed over the outline of the letter which is thus transferred to the undersheet. The disc(2) is then rotated to bring the next letter into position and the stencil moved along the straight edge(10) which abuts against the straight edge(9) of the box(3).

Title: Solid state oscilloscope system - operates using LED or light-conducting diode matrix to form flat display area
Inventor: SCHIELKE GUENTER
IPC: G01R13/40
Filed: 1977-08-05
Abstract: In order to obviate the problems associated with CRTs such as the requirement for EHT supplies and the absence of a flat display, it is proposed to use a matrix of light emitting diodes for the readout. The display is driven by an integrated circuit containing Schmitt triggers which convert the analogue input signal into a quasi-digital signal to provide outputs which drive the individual LED elements. The display devices are preferably formed as a matrix on a large scale integrated circuit which also contains the devices necessary to perform the scanning function. As an alternative, a liquid crystal display may provide the readout in place of the LEDs.

Abstract: Concrete of high strength is prepd. from a mixt. contg. 400-600 kg. of Portland cement/m3 concrete. The mixt. also contains 3-30 wt.% of insoluble anhydrate (type II) and 0.1-3.0 wt.% of a cement dispersion agent, both based on the wt. of Portland cement. Concrete moulded parts are obtd. by mixing the above ingredients, opt. contg. Al2 (SO4)3. 16-17 H2O, a cement expansion agent and a powdery pozzolano material, and adding water to a water:cement proportion of 25-35 wt.%. 38-48 wt.% of a fine aggregate is added. After moulding the concrete is subjected to a presteam treatment, followed by a steam hardening at atmospheric pressure. High strength concrete is obtd., suitable for posts, pillars, etc., relatively quickly without requiring autoclave conditions. It has a high prestress with reduced relaxation. The concrete has no tendency to crack after hardening. In an example, a concrete contained a condensation product of beta-naphthalenesulphonic acid and formaldehyde (dispersing agetn).

Title: Electrical machine cooling air heat exchanger - has counterflow tubes and spacer tubes forming self supporting stack inside casing
Inventor: GARZMANN TRAUGOTT DIPL ING
IPC: F28F9/013
Filed: 1977-10-01
Abstract: The cooling system for air for cooling electrical machines, uses a cooling unit with an entry (2) and a discharge (4) connection for air to be cooled, at opposite ends. This flow is cooled down by counter flow over a set of tubes (7) mounted between the ends (5, 6) of the unit, through which cooling air is passed. These tubes are supported by distance tubes (1) of the same dia. interspersed between them, and supporting them, allowing the air to be cooled to circulate through the gaps. The distance tubes and cooling tubes can be interlocked to form a self supporting arrangement inside the casing. Alternatively, both sets of tubes can be immersed in molten zinc or tin to lock them together and also protect them from corrosion.

Title: Multiple wall condensation vessel - controls metal vapours condensation in metal vapour lasers
Inventor: POPP HANNS-PETER PROF
IPC: H01S3/03
Filed: 1978-01-02
Abstract: The vessel is used for cataphoretic metal vapour lasers, in which a position must be provided for ions recombination to the metal atoms migrating from the anode to the cathode inside the laser tube. This prevents uncontrolled migration of the metal vapour particles to the cathode and to the Brewster window. For this purpose a vessel is mounted between the capillary end and the Brewster window, on whose large surface, cold relative to the discharge capillary, the recombination takes place. The surface of the vessel is increased by multiple wall construction using restrictions etc.
