Title: Display system for numeric data in nine-unit code - uses four vertical three horizontal and two diagonal display strips to form digital numbers
Inventor: LUBS DIETRICH
IPC: G04B19/00
Filed: 1973-12-06
Abstract: The display system is designed for better readability of digital data (1, 2, 3...9) in visual numeric systems than has previously been possible. The composite unit has the appearance of a figure eight with two oblique 45 degree cross-bars through the upper and lower squares. By preferential illumination of some of the four vertical, three horizontal and two diagonal strips, it is possible to reproduce the required digits. The left and right upper and lower corners of the horizontal strips may be of different radii, as required, to improve the format of the digits produced. Sharp corners are illuminated for some of the digits, and rounded corners for others, so that all digits are uniquely produced from the same basic set of nine components.

Title: Wire feed mechanism using flexible cable - rotates part of cable to induce vibration and reduce friction
Inventor: TAYLOR EDWIN KNOX
IPC: B23K9/133
Filed: 1973-12-14
Abstract: The mechanism is particularly for conveying a wire of unlimited length along a hollow flexible cable, and comprises wire feed and distribution components, spaced apart and joined by a flexible cable. A control device coupled to the feed component rotates part of the cable so as to induce vibration in it and reduce friction between cable and wire. A drive mechanism on the feed component grips the wire and thrusts it forward inside the cable. The latter contains an oblong flexible internal packing to guide the wire. The rotary movement can be imparted by a bush inside the cable, connected at opposite ends to the feed and distribution components. The control device can be formed from a pair of rollers in contact with the wire passing between them and lodged in a recess.

Title: Holography multicoloured beam forming - parallel beam with coherent components produced by lasers and lens systems
Inventor: BAGBY JOHN P
IPC: G03H1/00
Filed: 1974-07-25
Abstract: The multicoloured hologram of the photographic plate is produced as an interference pattern giving all information for the image of the object. The spectral coherence of all components in the parallel beam is due to three lasers which produce partial beams of blue, green and red radiations the intensities of which are selected to produce a white light from their combination. Beam splitter separates the reference beam and the object beam with mirrors and lens controlling the spread of beam so as to cover the plate. The beam is controlled by a lens and covers object to form the reflected object beam impinging on the photographic plate.

Title: Hydraulic torque converter fluid cooler - several double-skinned plate elements are stacked into a packet within converter sump
Inventor: AAHLEN KARL GUSTAV
IPC: F16H41/24
Filed: 1975-02-11
Abstract: The arrangement serves for removing heat from hydraulic fluid used in torque converters fitted on heavy duty vehicles, on which the converter acts also as a hydrodynamic brake. Aftr a prolonged braking action, such as occurs when the vehicle is negotiating a long slope, considerable amount of heat is produced, which has to be quickly removed so as not to impair the operational qualities of the hydraulic fluid. The space saving design allows the cooler being futted within the sump of the converter with immediate fluid entry into the cooler. Each plate has an inlet and outlet opening. The openings of the same function are mutually connected. The two skins of each plate are welded together along the edges, the cavity between the two skins is maintained by beadings pressed into the sheets to create fluid passage ways.

Title: Tool with tapping shank for perforating plate - has mandrel piercing hole by heat and axial pressure
Inventor: ACKEL SABET
IPC: B21D28/24
Filed: 1975-08-16

Title: Vertical gas scrubber with partial mist pptn. - for gases entraining large quantities of dust e.g. in refuse incinerator
Inventor: HOELTER HEINZ
IPC: B01D50/00
Filed: 1975-10-25
Abstract: The gas scrubber allows mist pptn. in the vertical, with pptn. of large droplets in the fall zone and pptn. of fine mist in the deflection zone. The former is pref. carried out by an apertured or sieve-like surface separator. Due to the combination of vertically mounted crude gas supply zones over a spin generator, major sepn. between water and gas in the fall zone can be carried out without much loss of pressure and the gas-liq. stream which is specifically lighter is deflected and passed to means for fine mist precipitation. The scrubber is operated with a ratio of 10 kg water to 1 kg gas, which allows considerable savings in loss of pressure in a partial droplet pptn. system.
