Patent DE-3324282-A1 (DE)
Title: Parallel screw clamp
Inventor: SCHLITTER GEORG
IPC: B25B5/10
Filed: 1983-07-06
Abstract: For precision working in the construction of jigs and fixtures, dies, moulds, machines and the like, a parallel screw clamp has a great many advantages, for example when scribing or pinning together two parts (machine elements). Upon tightening a normal screw clamp, the parts are mutually displaced by the screw thread. However, the known parallel screw clamps are highly disadvantageous since the screw ends also protrude on both sides of the clamp half. It has been shown that these protruding long screws can be very troublesome in handling. The object on which the present invention is based therefore is to eliminate these "disadvantages". As a result of the modified arrangement of the front screw, the lower clamp half remains level. This results in the great advantage that the parallel screw clamp can be laid on the machine table as a base, thereby obviating the need for an "additional" parallel strip. <IMAGE>

Title: Apparatus for producing studded-paper webs for packaging purposes
Inventor: EMMEL LOTHAR
IPC: B31F1/07
Filed: 1983-09-23

Patent DE-3338674-A1 (DE)
Title: Transport harness
Inventor: MARON KARL-HEINZ
IPC: E21F13/00
Filed: 1983-10-25
Abstract: Transport harnesses for bundling bar material have hitherto been composed of a slinging chain, a suspension member and a chain-shortening hook with a tying ring through which the slinging chain passes. However, this type of construction has the disadvantage that the securing of the bundled material in position, especially on inclines and downhill sections, leaves something to be desired. The lifting height is also needlessly reduced on account of the distance between the suspension member and the chain-shortening hook. These shortcomings are now removed owing to the fact that a suspension lug 20 is allocated to the chain-shortening hook 9 next to the tying ring 18, and a locking element 8 is provided at the free end 7 of the slinging chain 3. The locking element 8 serves to fix the position of the chain-shortening hook 9 in the case of tightly bound bar material 1, whereas the suspension lug 20, when the suspension member 6 is hanging down freely, can be used at the end 5 of the slinging chain 3 as a suspension point for the transport harness 2. <IMAGE>

Title: Automatic conveyor system for sample stock vessels in an automatic sample injection system having a sample loop or in an automatic sample handling system
Inventor: APFEL HELMUT
IPC: G01N35/02
Filed: 1983-12-21
Abstract: The sample chain of an automatic conveyor system for an automatic sample injection system or sample handling system comprises various types of individual chain links which can readily be assembled and have a particular marking. The marking makes it possible to determine the identity of the type of chain link that is in the working position at a particular instant. Since a particular analytical method or sample handling method can be assigned to each type of chain link by means of a central control unit, the user is able to freely program the method sequence or sample handling sequence easily and rapidly by suitably assembling the individual types of chain link to form a sample chain.
Patent DE-3409019-A1 (DE)
Title: Composting preparation for enriching compost with all necessary minerals and trace elements
Inventor: RIED KARL-HEINZ
IPC: C05F9/04
Filed: 1984-03-13
Abstract: Composting has been used for a long time to feed organic waste material back into the natural cycle. However, experiments over several years have shown that all methods result in deficiencies which can be compensated for by adding rock mills which are rich in bases and algal lime and by adding animal proteins in the form of sanitised, i.e. precomposted, horse/sheep/cattle manure as well as horn and bone meal. Dried, finely ground herbs and green algae complement the compost material, which is then provided as a substrate for the edaphon as a nature-like soil cover. The natural soil cover is a prerequisite for extensive edaphon and thus guarantees a healthy and highly fertile soil. A product in the form of a mixture of basic rock meal, ground clay, algal lime, composted horse/sheep/cattle manure, horn and bone meal, green algae and selected herbs contains all substances which can be found in the natural soil cover but which are deficient in a range of compost materials. Admixing a finished composting preparation prior to the composting process therefore allows a high-quality soil substrate to be produced from any organic waste material by means of recycling: the basis of any humus soil.
Patent DE-3417436-A1 (DE)
Title: Method for flash exposure in a camera having a fixed focus lens
Inventor: BRAEUNING GERHARD
IPC: G03B7/16
Filed: 1984-05-11
Abstract: In a camera having a fixed focus lens and built-in flashlight unit, the first step is for a first flash having a low flash energy to be emitted in conjunction with a small camera aperture to expose the short-range field and thereafter, if the flash-limiting electronic system does not respond to this, for the camera aperture to be enlarged and for a second flash, having more energy, to be emitted in conjunction with this larger camera aperture at a short time interval after the first flash. This results in the case of the small camera aperture in a good image sharpness in the short-range field due to the large depth of field. A large flash range in conjunction with a relatively low energy consumption overall is achieved by the second exposure at a larger camera aperture and with more flash energy.
Patent DE-3422515-A1 (DE)
Title: Arrangement for testing the operation of an Adcock direction-finding system
Inventor: CUNY ROLF DIPL ING
IPC: G01S3/02
Filed: 1984-06-16
Abstract: In an Adcock system, a test signal is radiated via a centre antenna or a support mast for testing the operation of the antenna system. When all individual antennas receive a field of the same amount and the same phase, the difference voltages of opposite antennas, and thus also the bearing voltages, ideally result in the value zero. If one of the individual antennas or a signal path in the antenna network is defective, a bearing voltage not equal to zero is obtained. When testing the operation, the bearing voltages are evaluated and displayed in the same manner as in direction-finding operation. The bearing angle indicated in the fault case specifies the angular position of the defective antenna element within the antenna array.

Patent DE-3503111-A1 (DE)
Title: Medicinal plaster
Inventor: LIEDTKE RAINER K DR
IPC: A61F13/02
Filed: 1985-01-31
Abstract: In order to improve the absorption of dermally applied medicaments by the skin, the medicinal plaster is made from a disc-shaped solid carrier mass containing the medicinal agents and melting at body temperature, the carrier mass in turn being located in a housing which is closed at the top, open toward the skin surface and fixed on the skin. During the gradual melting of the carrier mass induced by the skin temperature the medicinal agents are absorbed directly from the liquid phase of the carrier mass which distributes down to the microtopography of the skin. At the same time, the diffusion conditions with regard to the factors of transfer surface, diffusion path and temperature are particularly favourable. In another embodiment of the invention, an elastic pressure element brings about a steady pressure of the carrier mass disc on the skin surface.

Title: Contra-rotating distributor roller
Inventor: HERCHENROEDER KARL-FRIEDRICH
IPC: A01B29/06
Filed: 1986-03-25
Abstract: The optimum preparation of the fields after harvesting comprises: loosening the topsoil down to the plough pan, good covering of the plant residues in the upper layer of soil which is permeable to frost and air for better composting. This optimum soil cultivation without ploughing is carried out in some cases with considerable expenditure in terms of machinery. A favourable alternative thereto is afforded by the combination of a heavy cultivator with a double-heart share, "contra-rotating distributor roller" and clod breaker or packer roller. The double-heart share loosens the soil down to the plough pan and builds up a ridge. The "contra-rotating distributor roller" distributes the soil over the plant residues. The packer or clod breaker roller compacts the layer of soil thrown up. The following fitting features of the "contra-rotating distributor roller" should be noted: fitting after the last row of tines. Ahead of the packer or clod breaker roller with friction wheel drive by the latter. Height-adjustable relative to the packer or clod breaker roller. Parallelogram suspension, especially for overall working depth adjustment from the tractor.

Filed: 1986-04-04
Abstract: An opto-electronic display device is proposed with at least one proximity detector arranged in its peripheral region, serving to switch on, off or switch over the display by means of an electronic circuit controlled by the finger of the user. In order to produce a simple, exchangeable proximity detector which is essentially insensitive to disturbances or humidity, an infrared light component (11) is used comprising an infrared emitter (13) and receiver (14) adjacent to one another and arranged axially parallel or slightly tilted in relation to one another, located in the vicinity of a specifically allocated control zone (12) of the display device (10). In this way the light (16) radiated by the infrared emitter (13) is reflected by placing a finger (15) on the control zone (12) towards the receiver (14). This reflection initiates a switching process in the control electronic circuitry.
