Title: Tailgate for lorries or the like
Inventor: KNUESTING GREGOR ING GRAD
IPC: B60P1/44
Filed: 1981-03-30
Abstract: Tailgate for lorries or the like, a platform which can be pivoted about a horizontal axle by means of hydraulic cylinders being supported by two parallelogram linkages which are provided at a lateral distance from one another and are vertically movable between the loading space and floor level by means of at least one hydraulic cylinder. The hydraulic cylinders are integrated in the vertically pivotable lifting mechanism so that they pivot along during the upward movement and downward movement of the platform. The entire length of these hydraulic cylinders which are involved in pivoting is realised as a function of the length of the links of the parallelogram linkages, which length is in turn determined by the maximum lifting height of the respective tailgate. Each hydraulic cylinder which is involved in pivoting has a cylinder-piston assembly which is identical for different lengths of the links (maximum values of tailgate lifting height) and can thus be used for different rated sizes of tailgate and has a piston rod which is divided outside the piston tube and in which an extension or connection element which provides the respectively required set length, in particular a sleeve which is screwed between a piston-side piston rod stump and a platform-side bearing part is intermediately connected. <IMAGE>
Patent DE-3112932-A1 (DE)
Title: Hydraulic valve
Inventor: BRUNNER RUDOLF
IPC: F16K15/04
Filed: 1981-03-31
Abstract: Known ball non-return valves have the disadvantage of having a large overall height as a result of the diameter of the ball and the ball stroke. Plate valves are therefore used when there is little space, which valves require careful processing. The proposal has finally been made to use a mushroom-shaped shut-off body in the pressure and suction valves of a hydraulic pump element, which shut-off body is cut from a blank. The object of the invention is to produce a hydraulic valve which is distinguished by the fact that it is easy to produce. According to the invention, this is achieved in that a closed spherical segment is provided for the shut-off body to act as a sealing surface. As, despite the presence of a spherical sealing surface, only a part, and not all, of the diameter of the ball is present in the opening direction, which part depends on the size of the spherical segment, the overall height can be kept very low. It is especially advantageous to produce the shut-off body from a conventional ball-bearing ball, by cutting out the supporting surface for the spring and the shaft to guide the shut-off body. Conventional ball-bearing balls of all sizes can be obtained cheaply and can be machined quickly, easily and in large series using conventional machine tools with simple tools.
Patent DE-3114996-A1 (DE)
Title: Method and apparatus for lining vertical to inclined spaces in underground working, preferably boreholes, with a construction material hardening in a formwork space
Inventor: DUERRFELD WERNER DR ING
IPC: E21D5/00
Filed: 1981-04-14
Abstract: The invention relates to a method of lining vertical to inclined spaces in underground working, preferably boreholes, with a construction material, for example concrete, hardening in a form space defined on the outside by the side walls of the space and on the inside by a formwork. The formwork skin, after the formwork is placed in the space to be lined by means of its supporting structure, is set to the inner dimensions of the lining and, after the construction material is poured into the forming space and has hardened, is relieved of load and is consequently shifted or removed from the space. The purpose of the invention is to line mine spaces having a clear cross-section corresponding to the normal variation in their diameters with a hardening construction material in such a way that, even under unfavourable rock conditions, which are possibly accompanied by an excavation gradient of the rock, the lining is preferably attached frictionally to the rock and in special cases to an existing provisional lining, in which arrangement continuous ventilation is to be maintained. To this end, provision is made for a tube provided with a hollow casing consisting, at least on the outside, of fabric tubing forming a cavity wall and serving as formwork skin to serve as the formwork, which tube is suspended with the tube axis in alignment with the space axis or set up coaxially to the latter and is set to the inner dimensions of the lining by filling the casing (60) with a pressure-exerting medium, which filling acts as a supporting structure for the formwork skin, and for the pressure from the casing to the formwork skin to be set or controlled in accordance with the respective filling level of the liquid construction material in the formwork space and for it to be kept above the hydrostatic pressure in the formwork space until the construction material has hardened, and for the pressure in the casing to be reduced to such an extent that the casing is released from the lining in order to shift or remove the formwork.

Title: Occipital acupressure cushion
Inventor: YOUNG-HO CHO
IPC: A61H39/04
Filed: 1981-07-02
Abstract: The occipital acupressure cushion has two protuberances at its front which generate the acupression pressure and are formed such that they replace the thumb and index finger used in the conventional acupressure method and exert the pressure in the same way when the back of the head is placed on to the cushion. The cushion furthermore has a trough-like depression corresponding to the human occiput. This cushion can thus be used to apply acupressure on the occipital nerve at any time without requiring somebody experienced in acupressure methods.
Patent DE-3128954-A1 (DE)
Title: Devices for peeling shrimps
Inventor: THOMSEN WERNER DIPL ING
IPC: A22C29/00
Filed: 1981-07-22
Abstract: The device improves the peeling process according to the main patent, by regulating the frequency of the crushing-out actions according to the degree of peeling achieved. To this end, a pressing-out roller plane is made to adopt an inclined position (in an axial direction), so that shrimps resting on the top will progressively move to sections lower down under the force of gravity between the crushing-out actions. In so doing, they come into contact with stripping elements, such as combs, which move in the opposite direction to the shrimps. The distance between the combs and the crushing rollers can be adjusted. In the upper sections, longer distances are used; these are the sections where accumulations of shrimps must be thrown back and only a single layer allowed to pass through. Further below, the distance is narrowed, until the combs above the lower sections of the plane are at a minimum distance and only permit the passage of shrimp meat from which the shell has been fully removed and which exhibits a corresponding degree of thinness. The drawing shows the arrangement of a chain drive, which supports combs, above a crushing roller plane, with the direction of movement marked in. <IMAGE>

Title: Arrangement and process for generating an electric charge image
Inventor: HEINRICH HANS DIPL PHYS DR
IPC: G03G5/043
Filed: 1981-09-25
Abstract: The invention relates to arrangements and processes for generating an electric charge image corresponding to a radiation image on the electrically insulating layer (4) of a layered structure, in which the insulating layer lies on a photoconductive layer (2) and the latter lies on an electrically conductive layer (1). However, in this case difficulties arise on account of the properties of the known photoconductors when it is desired to remove the original charge image or to equalize the charge. To this end, the invention provides the interposition of a further light-sensitive photoconductive layer (3) between the X-ray-sensitive photoconductive layer (2) and the electrically insulating layer (4), which transmits the light to which the additional photoconductive layer (3) responds. The invention is especially suitable for application in medical X-ray diagnosis. <IMAGE>
