Patent DE-2904297-A1 (DE)
Title: Automatic icy road warning sign - automatically swings from horizontal to vertical position when ice forms on it
Inventor: KONRAD ERICH
IPC: G08B19/02
Filed: 1979-02-05
Abstract: The warning sign is placed in the open, near roads, to give a visual indication of icing conditions. It consists of a triangular sheet (6) with a warning signal portrayed on it. It is pivoted about a horizontal axis (2, 3, 4) so that more surface area lies to one side (8) than the other (6). A counterweight (7) on the smaller side normally holds the sign in a horizontal plane against a stop. When icing conditions occur, the greater weight of ice forming on the larger side (8) overcomes the counterweight and the sign swings into a vertical position. The edge of the base of the triangle (9) is turned up to form a rim to prevent the sheet of ice sliding off.

Title: Gas discharge display screen substrate - receives conductor traces by thick film deposition on masked photolacquer coated thin film layer
Inventor: ADELHOFER HELMUT ING GRAD
IPC: H01J9/20
Filed: 1979-07-24
Abstract: Glass substrates, carrying electrode conductor tracks for gas discharge display screens containing Penning gas mixtures, are produced by applying to a glass substrate a thin nickel film, covered by a layer of photolacquer. A mask for the conductor track pattern is used to expose the thin nickel film for this pattern, followed by nickel deposition on the exposed thin film which was not masked. The photolacquer remnants and the nickel film below them are finally removed by conventional techniques. This creates a continuous process for the application of such conductor tracks which saves cost and has a high productivity of high-quality display screens.

Patent DE-2944157-A1 (DE)
Title: Pulse measurement process using converter - determines if difference between beats exceeds desired value
Inventor: SCHAER FRIEDRICH
IPC: A61B5/024
Filed: 1979-11-02
Abstract: The process measures the pulse beat of a person, using a converter to produce analogue electrical signals from the latter. These are processed to give a needle impulse per beat, the time interval between adjacent impulses being determined by timing signals, and the pulse rate per minute thus calculated. A first phase determines whether the difference between two directly successive pulse beats per minute exceeds a desired value. If it is equal to or less than the latter, a second phase comes into operation, forming the mean value between the two pulse beats, which appears as the first indicated value.

Title: Paper making pressure roller - has swivel bearings at ends to allow bend adjustment
Inventor: SCHIEL CHRISTIAN
IPC: F16C13/02
Filed: 1980-06-28
Abstract: The mantle of the pressure roller with an adjustable bend, for paper manufacture, is supported at both ends by a swivel bearing at least, through the yoke (7). The hydraulic support mechanism within the roller mantle carries supporting forces from the yoke to the roller mantle. Both ends of the yoke have supporting surfaces resting on pedestals with the space between these surfaces along the vertical centre (m) being equal to or only marginally greater than the gap (I) between the bearings of the counter roller. The gap between the swivel bearings for the roller mantle is approximately equal to the space (I) between the counter roller bearings. A collar piece ranges from the pede pedestal within the roller mantle at each roller end for the yoke support surfaces. The design allows the bend to be applied at the ends of the roller, without increasing roller dimensions, so that the required pressures can be applied along the roller length. It also allows a drive to be fitted easily.

Title: Frame fixture for bicycle pedal lever holder - has pedal lever holder fixed to saddle carrier tube and return strap tensioner and stirrup to pedal
Inventor: DICHTL PETER PAUL
IPC: B62M1/24
Filed: 1980-07-09
Abstract: The bicycle has its pedal lever hanger fitted on connecting struts fixed by a tube clamp to the bicycle frame on the tube between the saddle and the pedal bearing housing instead of the rear forks. This allows greater forces to be exerted without damage to the frame. The rubber pedal return strap, which stretches with use, can be shortened by winding the strap round rod carrying discs at each end to stop the strap sliding off the rod. To ease the return of the pedal a stirrup is added above the pedal. This stirrup is adjustable to the size of the rider's instep.

Filed: 1980-07-14
Abstract: The orinting ink metering system has a number of blades alongside each other, adjustable in relation to the surface of an ink transfer cylinder. so as to regulate the thickness of the film of ink on the latter. The ends of the blades (5) adjacent to the cylinder surface are wedge-shaped. Their points (6), protruding into the ink, determine the size of the ink gap (17). The wedge surfaces(18) include an obtuse angle (beta) with a radial olane (20) of the cylinder (2) at the ink gap, and an adjusting mechanism slides the blades to and from the cylinder.

Title: Vehicle steering column mounted switch - has arm swung above spring-loaded contact strip to operate window washers and wiper
Inventor: MUTSCHLER ERICH
IPC: B60R16/00
Filed: 1980-08-16
Abstract: The multiple position switch mounted on the steering column of a vehicle has a switching arm (31) terminating in a pointed tip (36) which is moved against a number of indentations along a control track (34) for the switching positions. This arm travels above a moving bridging member (60) which in one position bridges two contacts and in another position bridges three contacts. The bridging member rests on one end of one contact to form a permanent connection with it. The second switch position is a self releasing position. In the first position, the rear window wiper is operated, and in the second position, the rear window washer is operated. It is also moved into a position to operate the front window washer. The bridging member itself is also raised and lowered by a spring between different switching positions.

Title: Rapid desorption of activated charcoal with steam - by heating with satd. steam under pressure and desorption with superheated steam at lower pressure
Inventor: SUSSMANN KLAUS
IPC: C01B31/08
Filed: 1980-08-16
Abstract: In the desorption of activated charcoal (I) with steam (I) is heated to 110-210 (120-160) deg.C with satd. steam under pressure, then the pressure is lowered (to atmos. pressure) and desorption is carried out with superheated steam at 110-210 deg.C (the same temp.).

Title: Safety field strength reduction system - has cascade of reduction plates on glass column with dia. progressively increased towards foot of column
Inventor: VORREITER LEOPOLD DR ING
IPC: H05F7/00
Filed: 1980-08-16
Abstract: The system is primarily intended for field strength reduction of lightning currents for possible utilisation. It comprises a glass column with several concentric reduction plates. The latter are downwards open and their diameters are steadily increased in the direction of the column foot. They are arranged in horizontal positions and form a reduction cascade. Each plate has preferably a concentric aperture with outwards pointing short collar and of a diameter corresponding to that of the column. Thus it is possible to secure each plate closely round the glass column, using a clamping ring of good conductive metal. The ring carries a current terminal, while the plate edge has an even number of electrodes as output points. The outer plate edge may be beaded and both plate surfaces may be completely coated with a thick layer of an insulating substance.

Title: Free standing solar heat collector for heat pump - has helically arranged hollow blades in sets radiating from hollow vertical post
Inventor: BINKERT HUGO
IPC: F24S90/00
Filed: 1980-08-20
Abstract: The solar heat collector to be combined with a heat pump is formed as a free standing unit instead of forming a wall or roof cladding. This is intended to avoid adding loads to the building structure due to ice formation etc. The unit consists of superimposed sets of blades mounted on a vertical concrete tube, each set being arranged in a helical pattern around it, in fan formation. The blades of each set are vertically spaced and radially offset to avoid casting a shadow on the set below. Each blade can be a double blade, with two hollow arms for circulating a heat exchange liquid, extending outwards from a central core. This core is attached to the vertical supporting tube which is divided by a central helical partition forming supply and return channels for the circulating liquid.
