Title: Cct. including liquid crystal display elements - has components oscillating between battery and earth potentials using voltage dividers and diodes
Inventor: WELLHAUSEN HEINZ DIPL ING
IPC: G09G3/36
Filed: 1973-12-07
Abstract: The liquid crystal display unit is formed by a pair of transparent plates, between which are two sets of electrodes, one a pair and one two pairs, which respond to different combinations of two input voltages A, A' and B, B'. Surrounding the display unit is a circuit with resistors and transistors between the positive battery D.C. potential line and the (earthed) negative line, which forms a set of voltage dividers, the voltage levels being controlled by four diodes. The effect is to produce a sequence of fluctuating potentials which sequentially energise the liquid crystals. The electrode arrangement is such that nine combinations of electrode discharges are possible, yielding nine different configurations.
Patent DE-2361547-A1 (DE)
Title: Cathodic protection of buried metal objects - using periodic switch-off potential for adjusting protective current
Inventor: ORTMANN KARL HEINZ
IPC: C23F13/04
Filed: 1973-12-11
Abstract: A protective current circuit is used and the buried object or a part of it, e.g. a test-piece, is periodically switched out of the circuit for an adjustable interval of time, the switch-off potential being measured by a comparator and compared with the desired potential; the difference between the two values is used to adjust the protective circuit. In districts where there is no influence due to stray currents, a switch can be located between the protective device and the object and periodically switched off, e.g. for 1 second alternatively, a test-piece made of the same material as the object can be located alongside but insulated from the object and periodically connected to it, then switched off to obtd. a potential fed to the comparator. The circuits may use electro-mechanical, electro-magnetic, or electronic devices. Used for steel pipelines or steel containers. Precise control of protective current, even when stray currents are present, is obtd.

Behind the hole are four, adjacent, overlapping plates held by struts so that they can be moved sideways. From each plate a strap projects held by a threaded tension spring the other end of which is attached to a strut held between the side-pieces.

Title: Non-linear digital frequency converter for electronic processing - has additional operation carried out in response to interrogation signal
Inventor: HOFMANN DIETER DR PHIL
IPC: G01D3/02
Filed: 1974-05-06
Abstract: When the converter is connected to a measuring transformer with a frequency output and a non-linear relation between the measured value and reciprocal frequency in response to an interrogation signal, the digitised measured value is formed as the final total of an addition operation. This operation progresses within a period of oscillation of the measuring transformer of a multiple thereof, whose cycle controls an oscillator of stable frequency and whose sum terms, constant over fixed time intervals, are supplied by a programmable fixed-value memory, provided that there is a constant relation between measured value and transformer frequency.

Patent DE-2422948-A1 (DE)
Title: Milling cutter for making accurate parallel sided groove - has tumbling motion to oscillate tool tips across groove width
Inventor: BAUDERMANN ADOLF
IPC: B23Q1/54
Filed: 1974-05-11
Abstract: The parent patent describes a method of milling to obtain highly accurate narrow grooves in a flat-bounded portion of a workpiece, esp. groove having parallel flanks; two or more cutting edges revolve around a common axis, the one cutting edge being at the forward side of the revolving miller and the other being at the rear side; in addn. to the linear feed motion of the revolving miller, a reciprocating motion is superimposed axially, thus defining the width of the groove cut; the maximum stroke of this reciprocating motion is therefore equal to the difference between the total width of groove to be cut and the width axially across the two cutting blades. In the patent of addn., this superimposed axial reciprocating motion is obtd., by a tumbling action of the milling tool around its acis, without the need to introduce any axial motion. The vibration troubles arising from a rapid axial reciprocating motion are liminated, since the present method does not involve any appreciable out-of-balance forces.
Patent DE-2425420-A1 (DE)
Title: Frusto conical yarn bobbins - with bobbin entry stop means located on inner bobbin wall
Inventor: KAMP HEINZ

Locking means disposed adjacent the lower end of the bobbin is formed by a flange whose i.d. is smaller than the o.d. of the smaller end of the bobbin.
Patent DE-2426384-A1 (DE)
Title: Roll-straightening of bars and tubes - using sideways feeding of the rolled product into straightener to avoid roll damage
Inventor: LINDEMANN HANS
IPC: B21D3/04
Filed: 1974-05-31
Abstract: Process for straightening bar-shaped rolled material, e.g. g tubes, shafts etc., using a two-roll straightening machine where the rolls move the bar along its longitudinal axis and also rotate it. The novelty is that prior to straightening, the roll gap is increased so the bar can be inserted without initial contract with the rolls and the gap is then reduced so the straightening operation can be carried out; and that straightening is ended before the tail end of the bar leaves the rolls which are sepd. so the bar can be removed. In the pref. device, the bars are both inserted and removed sideways and the ends chamfered before or a after straightening. Prevents wear and/or damage to the straightening rolls arising from the curved ends of the bars.
Patent DE-2436690-A1 (DE)

Filed: 1974-07-30
Abstract: The relay includes an AND circuit connected to the store output and generating an "on" and "off" signal when the signals preset in the store coincide with the binary input signal digits. The store contains a number of bistable selector switches, each storing a binary signal "1" or "0", so that the binary signal is represented by the digits set by the above switches. The switches have a number of separate terminals and a number of push-buttons which short-circuit pairs of terminals. They also serve as indicators.

Title: Anchor winch drive - has epicyclic gear train planet carrier and annulus selectively coupled to windlass
Inventor: RHEDIN KLAS GUNNAR NATANAEL
IPC: B66D1/72
Filed: 1974-08-08
Abstract: The sun wheel of an epicyclic gear train is coupled to the input, while the planet carrier and the annulus are coupled selectively via gear trains to the windlass. When both are coupled to it together it is driven at low speed and high power, while speed is high and power low when only one is coupled to it, while the other is braked. Both gear trains can be coupled to the same gearwheel driving the anchor capstan. One gear train can have a reversing mechanism, with each train having a gear running in the same direction and meshing with the same gearwheel at different points, thus driving it together, when both drives ar engaged.

Title: Double-action lever drive - designed for hour shaft in fall-plate clockwork with ratchet wheel
Inventor: STEMME WALTER
IPC: G04B19/20
Filed: 1974-09-05
Abstract: The double-action lever drive for the drive of an hour shaft has a movable pawl engaging the ratchet wheel, and a minute shaft driven by the movement. It comprises a two-armed ratchet lever similar to an escapement lever, directly driven by a crank rotating together with the minute shaft. Its oscillating motion acts on the ratchet wheel mounted on the hour shaft. Operative sides of teeth on the two lever arms operate in opposite senses. The friction coupling for hand adjusting and the reset stop are replaced by a single setting, and components and space requirements are reduced.
