Patent DE-3012885-A1 (DE)
Title: Producing high flushing pressures in filter sectors - by aligned apertures permitting flow into one sector only
Inventor: MOLL HANS-GEORG DR ING
IPC: B01D24/46
Filed: 1980-03-31
Abstract: Filters or other appts. for treating water and which periodically undergo reversed flow for flushing the clogged filter material are divided into sectors by means of partitions. Access to these sectors is through two concentric apertured sheets movable relative to each other. In one position, for normal operation, these sheets permit equal access to all sectors, but in a second reversed-flow position used for flushing, only the apertures leading to one sector at a time are left free, causing a considerable increase in flushing fluid pressure. The apertures sheets are rotated manually or mechanically until all the sectors have been flushed. Used with appts. for cleaning or chemically treating drinking water, bath water, waste water, etc. The high pressure produced and desirable for fluidising the filter material etc. would otherwise require stronger pumps and piping.

Title: Pressings made of stainless or heat resisting steel powder - which is atomised in inert gas and then driven by inert gas stream against impact plate to reduce particle size
Inventor: AASLUND CHRISTER
IPC: B22F3/12
Filed: 1980-05-23
Abstract: Parent patent described a powder which is atomised in inert gas, esp. Ar. At least the powder above a specific grain size, esp. 0.6 mm dia. is driven by an inert gas against an impact plate, or towards other inert gas streams contg. the powder, so that the latter is crushed and/or cold worked. The inert gas is pref. Ar, N2, and/or other gases not reacting with the steel powder. The powder is next made into a compact, esp. by cold isostatic pressing; and the compact may be subjected to further treatment, esp. hot- extrusion or-rolling, or hot isostatic pressing. The pref. plant includes a chamber fed with a gas stream contg. the coarse powder so the latter meets an impact plate in the chamber. A polymer mould is pref. used for compacting the powder. The crushed powder has a very low 02 content and improved properties,esp. good pressability and high density.

Title: Cultivator for mounting on tractor - has adjustable height implements driven from tractor power take=off shaft
IPC: A01B49/02
Filed: 1980-05-29
Abstract: The cultivator which can be mounted on a three-point support at the rear of a tractor is driven from the tractor power take-off shaft. It has a frame (36) with a cross-beam (110) which supports levelling blades (107) which fill in the ruts formed by the tractor wheels (38). A housing (21) mounted below the frame (36) supports a rotary digger (20) which throws the broken soil against a rake (24) with saw teeth edges (25). A soil breaking rotor (202) with radial teeth (204) completes the digging process. A scraper bar mounted behind the rotor removes particles of soil tending to stick to the rotor. All the implements (107,20,24,202) are adjustable for height and can be easily removed and replaced when required. Since the cultivator is entirely supported by the tractor it does not affect its manoeuvrability.

Title: Inflatable safety bag for mine-working - contg. several independently inflatable cells inside outer bag, esp. of PVC fabric
Inventor: SCHLIMBACH HEINRICH
IPC: E21F11/00
Filed: 1980-12-16
Abstract: Elastic, flexible bag for protection, retaining, cushioning and similar purposes, partic. in underground mines consists of two or more pressure cells which can be inflated and/or deflated completely independently from each other. The pressure cells each form a separate, complete elastic bag, all these bags are contained inside a single, flexible outer sheath or sleeve. Puncturing or collapse of a single cell does not cause the entire bag to deflate. This is of particular importance where safety considerations arise, for example in upholding unstable slopes, roofs, etc. In addn. the bag is much more easily handled and cells can be taken independently to the surface for repair. The outer sleeve or sheath is pref. of flexible PVC fabric. A number of inflatable bags of this type may be assembled or stacked to form a protective wall.

Patent DE-3116880-A1 (DE)
Title: Supplementary drive for vehicles
Inventor: HILDEBRANDT SIEGFRIED
IPC: B62M13/00
Filed: 1981-04-28
Abstract: A supplementary drive, which can also be retrofitted, for vehicles, in particular wheeled vehicles, is proposed. The supplementary drive is mounted in such a way that the rotation of the wheel to be driven cannot be adversely affected. In the case of two-wheeled vehicles, in particular bicycles, the supplementary drive cannot lead to a displacement of weight on one side. In this case, flywheels can be drive-connected, in a disengageable fashion, to one of the running wheels to be driven, are mounted outside the tread of the said wheels and are attached on a shaft which receives between the two drive wheels a drive roller which is connected fixed in terms of rotation to the said shaft and can be coupled to the tread. Only a few millimetres of actuator travel is sufficient to disconnect the drive connection. The mounts for the shaft are displaceable radially with respect to the axis of the running wheel to a limited degree by means of a handle which extends as far as the handlebars or steering device. So that the flywheels do not lose rotation during braking, when the brakes are actuated the drive roller is automatically uncoupled from the tread, as a result of which the flywheels rotate freely. The flywheel effect which is then stored can be used after the braking process to get the vehicle or bicycle moving again more quickly and in a more energy-saving fashion.

Title: Process and apparatus for the defined cooling of plate-shaped bodies by loss of heat to boiling coolants
IPC: A01N1/02
Filed: 1981-10-27
Abstract: The invention mainly relates to a process for the freezing of cell suspensions which are in a plastic bag for the purpose of long-term preservation at low temperature. The required defined cooling rates differ widely for each type of cell and are achieved by altering the insulating layer of a freezing container. This freezing container is sealed against boiling coolants but nevertheless is easy to open at very low temperature for the purpose of removing the frozen sample. The actual cooling is effected by immersion in the coolant such as, for example, liquid nitrogen. The resulting range of freezing rates is typically from 30 to 500 K/min, the volume of the cell suspensions is in the range 25 to 650 ml, the layer thickness of the suspensions placed on the plate shape is from 3 to 20 mm. The described process is designed for use in blood banks with minimal costs arising.

Title: System for the automatic transport of workpieces
Inventor: GRAF BERNHARD DIPL ING
IPC: B23Q7/14
Filed: 1982-04-02
Abstract: The invention relates to a system for the automatic transport of workpieces, comprising a conveyor belt which, by means of friction, transports workpiece pallets which can be halted at particular working positions by stops. The system furthermore comprises industrial robots which transport the workpieces from the workpiece pallets to processing stations and from the processing stations back to the workpiece pallets. By means of positionable stops, the workpiece pallets can be halted at any desired predeterminable positions. As a result, it is possible to use industrial robots which can only be moved along axes transverse and perpendicular to the conveying direction of the conveyor belt, a considerable reduction in the cost of the system thereby being achieved. The stops can be moved by means of a spindle driven by a motor and can be connected to a displacement measuring system. The workpiece pallets can be moved to defined positions by means of a control system.
