Title: Positioning device for type head carrier - has voltage reference points connected to voltage source and contact wiper moving over them
Inventor: KLOPPENBURG ERNST ING GRAD
IPC: G05D3/14
Filed: 1976-12-08
Abstract: A rotatable type-head carrier of a printing machine or similar is positioned in one of several positions determined by a reference element. An actual value generator is moved synchronously with the movable carrier. The actual value generator comprises a series circuit connected to a voltage source and consisting of voltage reference points with contacts between them. A wiper can move over them. Voltage collected by the wiper is applied to a nominal/actual value comparator. The comparison result determines the d.c. motor direction and angle of rotation for the carrier.

Title: Optical distance measuring for optical storage automatic focussing - using additional source and lenses for accuracy and sensitivity
Inventor: KRUEGER JOHANN ING GRAD
IPC: G02B7/32
Filed: 1976-12-15
Abstract: An optical distance measuring system for automatic focussing in optical storage systems controls an objective which focusses a light beam onto a storage plate over variable distance. It is designed to be simply constructed, very accurate, and highly sensitive and to avoid the signal-to-noise, measurement sensitivity and incidence direction stabilisation problems associated with semi-transparent reflector main beam systems. The system uses an additional light source, two lenses and a position sensitive photodiode arranged to produce a light spot in the objective focal plane or in the storage plane. One lens forms the spot image on the photodiode so that it moves with distance variation between plate and objective and the photodiode produces a position signal.

Title: Fluid measuring and metering system - is used in paint sprayer and performs dynamic flow measuring to control mixing valve
Inventor: TAUBE II FRANK ANTHONY
IPC: G05D11/13
Filed: 1977-07-05
Abstract: A system is used for accurately mixing two or more liquids and for dispensing the mixture. The system is generally adapted for use in paint spraying operations. The flow of one of the components is accurately measured by means of a flow meter and the measured value provides a signal to control a valve which, in turn, controls the flow of the other liquid. Periodically the volume of the first mentioned liquid is measured for a given time period so as to make necessary adjustments in the flow meter-value interconnection. An arrangement is provided for purging a mixing manifold immediately prior to the completion of the dispensing cycle to that none of the mixture will be wasted. The control arrangement includes air operated two and three-way valves.

Patent DE-2752907-A1 (DE)
Inventor: SCHREIBER HANS
IPC: E04C2/38
Filed: 1977-11-26
Abstract: The panel element has a frame which comprises profiles (2, 3) and encloses the sound-insulating mat (32). The profiles (2, 3) are connected at the ends via in each case one corner angles (4), with the result that the height and width of the panel element is determined by the length of the profiles and can be easily adapted to the installation ratios. The profiles (2, 3) and the corner angle (4) are each screwed down by means of a screw (8, 9), the screw clamping the profile to the corner angle by means of a clamping plate (7). The screws (8, 9) are screwed in at right angles to the profile longitudinal axis, with the result that, in addition to fastening the corner angle to the profile, they are also used for fastening the panel elements to one another, this making it easier to assemble large sound-insulating surfaces. On the side directed away from the sound, the panel element has a continuous metal sheet (24) and, on the side directed towards the sound, it has a perforated metal sheet (25), in order to keep the sound-insulating mat (32), inserted between said sheets, in position and to protect it from being damaged. <IMAGE>

Title: Tyre with retracting spikes - on flexible mountings extended by additional tyre pressure to negotiate icy roads
Inventor: METZINGER ERICH
IPC: B60C11/16
Filed: 1978-03-03
Abstract: The retracting spikes for the tyre have a hardened steel shaft with a widened base located in a blind hole in the tread.
