Title: Electronic flash system for a camera with a focal-plane shutter
Inventor: ISHIDA TOKUJI
IPC: G03B7/16
Filed: 1981-01-21
Abstract: A flash photography system is adapted for the combination of an electronic flashlight unit and a photographic camera with a shutter which, as in the case of the two-plate slotted shutter, exposes the film by means of a slot which sweeps over or scans the film surface at at least a few shutter speeds. In order to enable the film to be completely exposed for a scene which is illuminated by the flashlight, the electronic photoflash tube is controlled so as to emit light at a constant intensity for a period which suffices to cover the time during which the shutter slot completes its motion. The flashlight emission is set in operation in synchronism with the operation of the shutter, i.e. with the start of the scanning or sweeping of the shutter slot. The flashlight can be emitted before the operation of the shutter in order to determine a camera shutter aperture. The shutter is controlled electrically.

Patent DE-3119802-A1 (DE)
Title: Hydraulic control device
Inventor: ZIRPS WILHELM
IPC: B60T13/14
Filed: 1981-05-19
Abstract: The hydraulic control device serves to control the pressure medium, delivered by a pump (12), alternatively to an accumulator (35) or a consumer (114). Serving to control the pressure medium to the consumer is a flow-control valve (16) which only controls pressure medium to the consumer when the accumulator (35) is charged. Serving to control the flow-control valve is a pilot-control valve (41) which is additionally actuated via a control element (49) acted upon by the accumulator pressure, specifically when the accumulator is charged. Furthermore, a brake device (116) with a pressure-reducing valve (72, 85) is provided. The pressure-reducing valve (72, 85) controls hydraulic oil from the accumulator into the brake line when the brake is actuated. A control groove (115) on the control spool (16) of the flow-control valve ensures that no undesirable pressure can build up in the return space (19) of the flow-control valve due to leakage oil at the control spool, which would impair its function. <IMAGE>

Title: Method for scanning an object
Inventor: SAKAMOTO TAKASHI
IPC: G03F1/90
Filed: 1981-06-05
Abstract: The invention relates to a method for scanning an object, for example a contour of a master photographic image or a line image. The object is scanned by means of a set of sensor elements which are arranged in an optics head which is moved along the object in order in this way to obtain a position and a direction of the object. The optics head is guided in a controlled fashion in order to scan the object as a function of the measured position and the direction of the object. The object is reproduced by reproduction means which are moved synchronously with the optics head. The present invention improves this method due to the fact that the optics head is guided in accordance with line section data along sections of the object which the sensor elements can distinguish or trace with difficulty or not at all. These line section data are predetermined and represent a plurality of coordinate points. <IMAGE>

Title: Floatable oil-suction device
Inventor: STALLZUS HARRY
IPC: E02B15/10
Filed: 1981-09-26
Abstract: Arranged in a floatable oil-suction device is a floating body with an outer inlet ring and an inner suction ring with suction nozzle for connection to a vacuum line which leads to a tanker vehicle on shore or to an oil-recovery ship. This oil-suction device can be used from ship or shore and in large numbers in combination with known oil barriers. The proportion of water during suction can be kept down, since the oil film passes through relatively low openings at the level of the float lines into a calming zone in the interior of the inlet ring and passes from there via upper openings into the suction ring and the suction nozzle into the vacuum line. The entrained proportion of water can escape to the bottom from the calming zone through return openings.

Patent DE-3146012-A1 (DE)
Title: Auxiliary device for gripper looms
IPC: D03D47/12
Filed: 1981-11-20
Abstract: The present invention relates to an auxiliary device for gripper looms having blades which are movable to and fro between the end positions of the stroke and which serve as insertion members for the gripper rods which take up the weft yarn and transfer it in the middle of the fabric. Since breaks leading to consequential damage occur during the several hundred thousand load alternations which take place daily, the invention is intended to remedy this by providing limit switches, by means of which the gripper loom is stopped automatically when breaks occur. Since a break is preceded by incipient tears causing a lengthening of the stroke, this can be utilised to make contact with the switches, thereby reliably avoiding the disadvantages of the state of the art.
Patent DE-3148928-A1 (DE)
Title: Surface-controlled semiconductor device with self-stabilised value storage
Inventor: SCHEERER WALTER DIPL ING
IPC: H01L27/108
Filed: 1981-12-10
Abstract: The invention relates to a semiconductor device which is suitable as a monolithic storage cell for computers (Figure 1a,b) and comprises a field-effect transistor without source zone and with an electrical connection between gate and substrate. The stored value 1 is stabilised by the negative threshold voltage (VT) of the storage cell, as a result of which the potential of the inversion layer is more positive than that of the gate, which is positive for the stored value 1. If, for example, magnesium or cerium (both metals having relatively low work functions) is used for the gate, the threshold voltage (VT) becomes negative. A negative potential of the gate corresponds to the stored value 0. This potential is lower than the negative potential of VT and this value is stabilised by means of the electrical connection to the gate as a result of electrons from generation processes in the substrate. The storage cell is written into and read out by means of a field-effect transistor whose drain zone is connected to the gate of the storage cell. <IMAGE>
Patent DE-3148970-A1 (DE)
Title: Test-machine circuit arrangement for the damage-free clamping and resetting travel movement
Inventor: PATZSCH WOLFGANG
IPC: G01N3/06
Filed: 1981-12-10
Abstract: The invention relates to a circuit arrangement for cutting off the travel movement of the force piston as a function of the starting force during the clamping of the test body and for the prepositioned resetting movement after the break of the test body. The object of the invention is to obtain a selection of the travelling speed independent of the starting force, the possibility of using test bodies of differing length without adjusting of the crosshead, adjustability of the lowest possible starting forces independently of the maximum force and the assumption of any resetting position over the entire stroke range, including the zero mid-position. According to the object, an unambiguous relationship between force and path signals, functional reliability in the event of actual path values not equal to zero, starting force independently settable to zero and monitoring of the test-body break by means of an actual force value are obtained. The invention provides a counterforce member connected to the force cell and arranged contrary to the force piston. The force cell is branched off to a counterforce evaluation circuit which controls an alternative switching device. A force-comparison device and a path-comparison device are connected to this. Its output leads to a regulating device for the servo-valve and a resetting switch stage with output to the counterforce evaluation circuit.

Title: Ballast arrangement for gas-discharge lamps and a light unit having a ballast and at least one high-pressure gas-discharge lamp
Inventor: KEREKES BELA DIPL ING DR
IPC: F21V23/02
Filed: 1982-02-05
Abstract: The invention relates to a ballast arrangement for gas-discharge lamps, especially for high-pressure gas-discharge lamps which contain a discharge vessel in a hermetically sealed outer light-permeable glass bulb which is filled with a vacuum or gas filling. The ballast is provided at least with an element which limits the operating current of the gas-discharge lamp or with a similar unit but in some cases may contain for example a structural element, for example a detection and/or circuit element which provides for example the starting pulse, or another structural element which favours the use of the lamp. Its character is that the ballast is constructed as a rotating body which is essentially ring-shaped, cup-shaped or has a different shape and is provided with an inner opening, the inner jacket of the opening enclosing the neck part of the outer glass bulb of the gas-discharge lamp and being matched to the shape of the latter. The ballast may also form an undividable part of the gas-discharge lamp and hence highly favourable compact light sources or electrical lighting units can be constructed, especially with the use of high-pressure gas-discharge lamps which can replace the generally widespread incandescent lamps with a power of 40 to 100 W to save energy, without having to replace the fitting or the socket. <IMAGE>
