Title: Optical micrometer for radial graduation interval measurement - uses rotatable wedge element for graduation marking image rotation and displacement
Inventor: FEIST WIELAND DR ING
IPC: G01B11/14
Filed: 1979-06-23
Abstract: An optical micrometer for measuring the intervals between radial graduations is partic. for use with geodetic angle measurement devices with circular graduations. It enables optical shifting and rotation of the image of a graduation marking to superimpose it on a reading scale. The important optical component is a wedge (13) rotatable about an axis perpendicular to the plane of the circular graduations or an optically conjugate plane and to a refracting edge. The wedge angle depends on the radial graduation marker extensions, the optical rotation required, and the wedge material refractive index.

Title: Fuel injection control system for IC engine - has fuel in hydraulic control line to prime injectors when starting
Inventor: MAISCH WOLFGANG DIPL ING DR
IPC: F02M69/18
Filed: 1980-03-26
Abstract: The application is to a fuel injection system in which fuel quantity and pressure are automatically adjusted to engine operating conditions. For this purpose certain engine parameters, including air quantity, are used. At starting the air quantity is low thus the fuel inlet valves are practically closed and the injectors fill only slowly. To overcome this deficiency the fuel line (11) to each engine cylinder is connected to a hydraulic control line branch pipe at a point between the measuring valve (1) and the injectors (13). In each interconnecting pipe (38) is a non-return valve (37) biased to open if the hydraulic control line pressure exceeds the fuel line pressure. At starting such a condition exists. The fuel lines are rapidly filled from the pressurised control line fuel, and the fuel compressed to a point where significant air bubbles disappear. A quicker and more certain start up results. The necessary hydraulic control line circuit is made by a three way valve (35) which opens the branch pipe (36) after starting and blocks it during normal slow running.

Title: Heating cost metering circuits - have voltage dividers reducing value of electrical signal proportional to temp. difference between two sensing points
Inventor: HANSEN JENS PEDER FISCHER
IPC: G01K17/08
Filed: 1980-08-04
Abstract: The sensing circuits apportion heating costs, e.g. for the separate families of a block of flats. They are tamper-proof and sense differences in temp. Each circuit has two sensing points. An electrical signal is delivered when a temp. difference exists between them. This signal is proportional to the temp. difference but each circuit has a voltage divider to reduce its value. The installation is so arranged that if the colder sensing point of either circuit is artificially warmed, the reduction effected by the voltage divider is reduced. The temp. sensing points can be provided by the solder points of a thermo-element. The voltage divider can contain a positive temp. coefft. resistor situated near the sensing point normally recording the lower temp.

Title: Face-position measuring device V
Inventor: POHLE HELMUT
IPC: E21D23/08
Filed: 1981-05-29
Abstract: To determine the rate of advance and to monitor the face run or the position of the face conveyor, a face-position measuring device is proposed which consists of a mechanical and an electrical counting device, the triggers of which are allocated to a common spindle. This spindle is driven via a flat toothed belt, the drive pulley of which is connected to a deflection pulley which can be coupled and is driven by a further flat toothed belt. This further flat toothed belt is connected to a piston rod which is attached to a feed cylinder influencing the face conveyor. In the case of this face-position measuring device, a coupling influenced by the face hydraulic system is ensured such that only the movement in the working direction is recorded, whereas during the normal advance of the face conveyor the back-and-forth movements, i.e. the fluctuation in a positive and negative direction, are counted so that the fluctuation is eliminated. <IMAGE>

Title: Process for producing photographic images to be viewed in reflection, with improved spatial reflection, and the photographic materials used in this process
Inventor: MEYER ARMIN DR
IPC: G03C1/95
Filed: 1981-07-20
Abstract: In anisotropically reflecting white-opaque photographic bases, normal reflection conditions approximately obeying the cosine law exactly can be restored if, before application of the photographic layers to the base, a white-reflecting, photographically inert pigment is applied in layers, or this is incorporated into the lowest photographic layer next to the base. In this way, visible disturbing spots, which can be found, for example, in the treatment of images which have been produced on an anisotropically reflecting photographic base and have been retouched with pigment colours, are avoided.
