Patent DE-3237921-A1 (DE)
Title: Control device
Inventor: STUMPE WERNER
IPC: G05D16/16
Filed: 1982-10-13
Abstract: In control devices for compressed air or hydraulic fluid, e.g. compressed air brake systems of vehicles, a plurality of hysteresis-affected control and/or regulating elements are provided in a control chain, normally involving a control valve (13), a relay valve (1) and a regulating element (3). The element in the control chain with the greatest expected pressure reduction and the smallest expected characteristic line rise is appropriately arranged as the last element. This offers the advantage that, in the overall resulting hysteresis, this greatest pressure reduction of the element with the smallest expected characteristic line rise remains without effect. The individual regulating elements (1, 2, 3) are disposed in the control chain in the order K1>K2>K3, where K indicates the respective characteristic line rise of the respective regulating element (1, 2, 3) and where the element with the greatest expected characteristic line rise is inserted in the control chain upstream from the element with the lower characteristic line rise. In this way, the overall hysteresis of the compressed air control device is minimised without specific additional expense (Fig. 1). <IMAGE>

Title: Firing arrangement for rifles and pistols
Inventor: SCHAUB GEORG VON DIPL ING
IPC: F41A21/10
Filed: 1983-04-19
Abstract: The invention relates to current rifles and pistols, especially for sport, and to a superior arrangement, in which widely differing types - calibers - can be combined with one another. The invention is aimed at technical systematics, in which, by means of a recognised basic system, the correct choice is made and also the multiplicity of necessary calibers is advantageously covered. The invention leads to the knowledge that, with the arrangement according to the invention, a rifle or short-rifle pistol of a large caliber, for example an inside diameter of 12 mm, can also be so designed that smaller calibers, for example an inside diameter of 6 mm, in addition to the large caliber (shot), can be used in the same rifle, simply by inserting different tubes, designed especially as firing tubes, meeting all requirements and even affording advantages which are within the system. With the insertion according to the invention of a firing tube made of steel and of an inside diameter of 5-6 mm and, for example, an outside diameter of 7 mm into the strong system of the shot tube of an inside diameter of 12 mm, there is obtained, according to the invention, an arrangement which provides in the simplest possible way an ideal shot rifle and an especially fine and reliable small-caliber rifle for 6 mm, simply by the insertion of a 6 mm firing tube which is designed according to the invention. The invention is characterised in that the firing tubes ready for insertion ... with spacer centring ring discs of 12 mm ... Original abstract incomplete.
Patent DE-3316235-A1 (DE)
Title: Method and device for consolidating workpieces made of solid material forming hollow spaces or capable of shrinkage
Inventor: HAID JUERGEN
IPC: B27G1/00
Filed: 1983-05-04
Abstract: The workpiece (27) formed by a wooden board or the like has a hollow space at least open to the top inside the feed-in surface (63) defined by the annular rib (161) and, at least in the area of this surface, is supported with its supporting surface (43) in a sealing manner on a base. A valve injection tool (133), together with a nozzle plate (74) and a movable valve member (75), forms numerous valve nozzle units (76) and a cylinder space (152) to which a highly fluid, curable plastic is fed under pressure through a line (134). By lifting of the valve plate (85) by means of a servomotor (90), this plastic can thus be directed immediately into cracks and other hollow spaces of the workpiece, while the injection tool (133) presses the workpiece (27) with its supporting surface (43) in a sealing manner against a bearing surface under the pressure of a servomotor (39) via the plunger (38). After the curing and the reworking of at least the feed-in side (62), the filling bodies, formed by mostly transparent material, are scarcely noticeable. <IMAGE>

Abstract: The invention relates to the holder of a rim brake on the front fork or rear fork of a cycle, the brake housing being enclosed annularly by a receiving element (4) which is formed by two shell components (2, 3) which are welded to one another and form the bearing part of the fork in the region of the brake housing. <IMAGE>
Patent DE-3322581-A1 (DE)
Title: Dimensionally stable press tape
Inventor: BREMUS HERMANN-JOSEF
IPC: D02G3/40
Filed: 1983-06-23
Abstract: In order to bring the yarn system subjected to stress in the pulling direction to bear with full strength and without undesirable stretching phenomena, no crimps (a) caused by binding should be introduced into the load-bearing yarn system during the weaving operation. The tension of the yarn system, which extends in the pulling direction during subsequent use, must therefore be kept so high in relation to the intersecting yarn system (b) that the crimp affects only the intersecting yarn system. This weaving behaviour of warp and weft necessitates different measures, depending on whether the warp system is exposed to the subsequent effect of force in one direction or whether this force effect extends to the weft system (for example, in endlessly woven tapes). <IMAGE>

Title: Resonance vibration damper
Inventor: VIETS ADALBERT DIPL ING
IPC: F16F15/14
Filed: 1983-09-23

Title: Solenoid valve
Inventor: BARTHOLOMAEUS REINER DIPL ING
IPC: F16K31/06
Filed: 1983-10-17
Abstract: The invention relates to a solenoid valve in which the armature is arranged loosely on a sleeve, the ends of which interact like a control piston with the housing bore, as a result of which bearing points are formed by means of which the ingress of foreign particles into the interior of the solenoid valve, in particular to the armature, is avoided. The depositing of foreign particles on the armature, which depositing is disadvantageous for the operability of the valve, is thereby prevented. <IMAGE>

Patent DE-3400738-A1 (DE)
Title: Rig for a sailboard, sail steering strap
IPC: B63B35/79
Filed: 1984-01-10
Abstract: By manual action on the sail retaining strap, the steering strap serving to simplify steering changes the sail pressure point on the sailing body to steer the sailing body into any desired position in relation to the action of the wind. The sail designed to simplify operation is held taut by the steering strap and thus ensures good steadiness through extra width of the sailing body. Therefore an easy-to-operate sailing object guarantees that, to release the difficult-to-operate surfing body, a steady sailing object can be sailed without the requisite change in weight, and in addition there are advantages of a surfing nature.
Patent DE-3402943-A1 (DE)
Title: Spring tension element
Inventor: GERRITZEN THEODOR DR MED
IPC: A61C7/06
Filed: 1984-01-28
Abstract: A spring tension element between the head belt (12) and the face bracket (16) of a dental adjustment has a first fastening element (10) for attachment on the head belt (12) and a second fastening element (30) on which the face bracket (16) can be suspended. A spring element (14) which is fitted on a first end of the second fastening element (30) and counter-acts displacement of the latter is housed in the body (20) of the spring tension element. If a certain tensile force is adjusted by suspension of the face bracket (16) in one of the recesses (32) in the second fastening element (30) when the dental adjustment is applied, this force can be directly read off at the markings (26) along a slot (22) produced in the body (20) along the movement path of the second fastening element (30), as a result of which optimum adjustment of the dental adjustment can be monitored at all times. <IMAGE>
