Patent DE-3126242-A1 (DE)
Title: Moulding of sandwich construction and semi-finished product for the production thereof
Inventor: ENGELSBERGER ERNST
IPC: B29C70/66
Filed: 1981-07-03
Abstract: The invention relates to a moulding of sandwich construction which is constructed, from the point of view of simple production, from a resin system which is fibre-reinforced in the cover-layer region and foamed in the core region. To ensure a high-strength design of the cover layers and clean separation between the fibre-reinforced resin zones and the foamed resin zones, the resin matrix is reinforced in the region of the cover layers by fibre layers with aligned fibre orientation, whereas the foam core is constructed of foam particles incorporated into the resin system with uniform, homogeneous distribution. Said foam particles are formed from highly storage- stable thermoplastic beads which are added to the thickened resin system before curing, are prefoamed and completely expand at the curing temperature of the resin. Accordingly, the corresponding heat-pressable semi-finished product for producing the moulding consists of upper and lower textile fabrics or scrims and an intermediate layer which is inserted between these and is a homogeneous mixture of the unreinforced, thickened resin system and prefoamed, thermoplastic beads added to said resin system with uniform distribution.

Title: Frictional body (scraper) for cleaning the inner wall of pipes
Inventor: RIEDEL ERICH O ING GRAD
IPC: B08B9/055
Filed: 1981-08-03
Abstract: The invention relates to a frictional body made of flexible and ductile material which effects a cleaning of the pipe inner wall of adhering foreign substances and, if appropriate, provides a corrosion-protective effect and anti-adhesive effect by the incorporation of granular material. For this purpose, substances having the external shape of granules or of a polydisperse granular material are incorporated as homogeneously as possible in the frictional body. During the passage, effected by hydraulic forces, of these frictional bodies through the pipes to be cleaned, the adhering foreign substances are scraped off. In a special design of the invention the incorporated granular material is of a composition which, also by the effect of friction, leaves behind protective layers on the inner wall of the pipes to be cleaned.

Title: Dual circuit pressure governor
Inventor: BERISCH VOLKER DIPL ING
IPC: B60T8/28
Filed: 1981-09-30
Abstract: In the case of a dual circuit pressure governor (1) an inlet (4, 6) for connection to a pressure source, an outlet (5, 7) for connection to a pressure consumer and a pressure control valve (8, 9) connected between inlet and outlet and spring-loaded in the opening direction are provided respectively for each brake circuit (2, 3). At a predetermined switch pressure the pressure control valve closes and in the event of a further rise in pressure influences the outlet-side pressure according to a predetermined control characteristic. Matching boundary faces of the control pistons (10, 11) of the two pressure control valves (8, 9) remote from the outlet define one part of a common pressure medium chamber (12), which is connected to the inlet (6) of the one brake circuit (3) and is closable by a deceleration element (13) responding in the event of a predetermined deceleration. In the area of the common pressure medium chamber (12) a piston (14) preloaded by a control spring (15) is located between the two control pistons (10, 11), which preloaded piston can be brought into locking engagement with the two control pistons (10, 11) particularly when the pressure medium chamber (12) is not admitting pressure and the pressure control valves (8, 9) are open. The control spring (15) with a particularly appropriate design has a progressive force/travel characteristic in order to approximate the actual brake pressure distribution to the ideal characteristic of a particular load state of a vehicle which contains the dual circuit pressure governor according to the invention. <IMAGE>

Title: Clamping device for a plate which can be displaced on a column
Inventor: JAGOB KARL
IPC: F16M13/02
Filed: 1981-10-15
Abstract: The invention relates to a clamping device for firmly clamping a plate, primarily the mounting plate of an adjustable-height vice, with respect to a supporting column. Known methods for firmly clamping the supporting column often lead to snug, flat contacts between clamping pieces and the supporting column not occurring if specific production tolerances are exceeded. The damage resulting from this, as a consequence of a linear contact, is avoided according to the invention in that the clamping piece can be arranged with a recess, which is matched to the circumference of the column, precisely opposite the apex of a through opening, provided in a profile, for the column, and can be pressed against the supporting column by means of an eccentric shaft, which is self-locking. The avoidance of the risk of a linear contact which is achieved in this way permits high contact pressure forces which are achieved in that, for the purpose of clamping, the clamping lever must always be pulled upwards from a position pointing downwards, so that the clamping forces can be applied.

Title: Fuel injection pump for internal combustion engines, especially diesel internal combustion engines
Inventor: FISCHER DIETRICH
IPC: F02D1/18
Filed: 1983-05-05
Abstract: A fuel injection pump (1) for diesel internal combustion engines comprises an injection timing device which is drive-connected to two pistons (3 and 4) adjustable by means of fuel pressure. The pistons (3 and 4) are coaxially arranged in a stepped housing bore (5) in such a way that the outer piston (4) is slidably connected both to the housing bore (5'') and to the inner piston (3). Both pistons (3 and 4) are subjected to the fuel pressure in the same adjustment direction according to the arrow >>A<< against the action of return springs (6 and 7) connected in parallel. The inner piston (3) has a carrier stop (9) for the outer piston (4) at a distance in the adjustment direction (arrow >>A<<). The ratio of the hardnesses of the return springs (6 and 7) and the pressure areas (10 and 11) of the pistons (4 and 3) is so selected that in the case of speed-related fuel pressure a first >>advanced<< injection timing adjustment is achieved solely by way of the piston (3). Only as the speed of the internal combustion engine increases do both pistons (3 and 4) act in concert for a further >>advance<< adjustment. <IMAGE>

Title: Staking and grinding roller
Inventor: FLEKAC FRANTISEK
IPC: C14B1/42
Filed: 1983-07-29
Abstract: In staking and grinding rollers for the treatment of leather, skin and fells, with staking elements (2) and grinding means arranged on the roller circumference, the problem exists of rapid and simple exchangeability of the grinding means. These must at the same time be of great effectiveness in order to overcome the grinding conditions which are difficult in the present case because of the greasing effect of the material to be treated. By way of solution, the grinding means have at least one grinding band (1a, 1b) which extends along the roller circumferential surface, specifically preferably helically with band windings lying next to one another. Advantageously, in each case two axial sections (I, II) of the roller are provided with two grinding bands wound in different directions. At their ends, the bands can be secured on the roller with clamping devices (3) which are easy to fasten and to release. <IMAGE>
