Patent DE-3938296-A1 (DE)
Inventor: WALDINGER ANDREAS
IPC: B65B23/22
Filed: 1989-11-17
Abstract: The packing device of the invention has a feed conveyor (1) located at an upper, feed, level (A) and a packing conveyor (2) located at a lower, packing, level (B) and driven to move at right angles to the feed conveyor (1). The two conveyors are linked by a bridging device (3) in the form of a chute with a multiplicity of adjacent guide grooves (34). The feed conveyor turns about two or more conveyor wheels (5, 5.1). The conveyor band (6) has at least on the outside a thick layer of a highly elastic, easily deformed material, such as rubber or a plastics material similar to rubber, in which outwards-facing grooves (7) designed to hold individual vertical packages (8) are moulded, giving the belt a toothed shape. The packages are arranged in line by the conveyor band (6) and conveyed over a support table (17) which is drawn back briefly by a compressed-air-operated cylinder (24) when the conveyor band is periodically halted, thus allowing a row of packages (8) to drop into the guide grooves (34) and be deposited on the packing conveyor (2) driven to move at right angles to the feed conveyor. In this way, the packages (8) are turned gently but relatively rapidly and simply on their sides and packed.

Title: Injection mould for bottle crates - where dividing partitions have holes and baseplate ridges and length of partitions is minimised so bottles do not fall through base
Inventor: KOOSE RUDOLF
IPC: B29C45/26
Filed: 1991-07-20
Abstract: Multi-part injecton mould produces e.g. bottle crates which have dividing partitions with holes and a base plate with holding ridges, plus core members which define the ends of the cavities producing those partitions. Cores have longitudinal ridges in areas where they stand out from a circular shape. Core member is not circular in cross-section but has four projectons and their reentrant parts diverge from the circle, so partitions are smaller. Diagonal ridges are sector-shaped to match the core and can be in all four corners. Other variants on the theme are also feasible, e.g. other shapes of the core members and/or bases of the crates. ADVANTAGE - Design prevents bottles from falling out through the base. Minimises length of partitions.

Title: Pressure cushion, for investigating behaviour of granular material - consists of two plates of which at least one is made of plastic-elastic deformable material
Inventor: KORTHAUS EKKEHARD DR
IPC: G01N3/00
Filed: 1991-09-19
Abstract: The pressure cushion in plan view has the form of a polygon or a rectangle (or a square) with chamfered corners. It consists of two plates of which at least one is made of a plastic-elastic deformable material. The plates are joined to form a cavity. One of the plates has bore allowing the cavity to be enlarged by a medium introduced under pressure. It is such that the plates have different sizes, with the larger plate folded over the smaller plate and joined at its edges to the smaller plate by means of pressure resistant joints. Pref. the smaller plate has a wall thickness equal to 5-10 times the wall thickness of the larger plate. The smaller plate carries a fastening element in the form of a snap stud in a pressure-tight joint, with the stud and the plate provided with a bore. The cavity is filled at least partially with a grid. The pressure resistant joints between the plates are produced by means of laser or electron beam welding. USE/ADVANTAGE - The method can be used in test installations where the behaviour of granular material subjected to triaxial loading is investigated. In contrast to known pressure cushions (which are prone to leakages under high pressures), the joint between the plates is no longer within the zone with max. deformation and tensile loading.

Title: Scroll-edge controlled injection pump for IC engine - has barrel inner wall ground out at suction port forming overflow at low speed
IPC: F02M59/26
Filed: 1991-10-31
Abstract: The pump has one or more pump elements. These each comprise a cam-operated plunger working in a barrel. A bottom scroll-edge on the plunger determines the end of injection and a top edge its beginning, dependent on load and in conjunction with a suction port in the barrel. The inside wall of the barrel is ground out to form a surface (15) joining onto the suction port (3). This forms an overflow port effective only at low speed. Its depth and height (t, h) is 0.1-0.2 mm respectively, while its width (b) is roughly that of the suction port. It can be sickle-shaped when seen in the direction of movement of the plunger (4). ADVANTAGE - Simplicity of production without sacrificing ability to vary the beginning of injection dependent on speed and load.
