Title: Mass exchange between suspended solids and solvent - in counterflow through semipermeable membrane, applied e.g. in prodn. of roasted coffee bean extract
Inventor: SCHREIN JUERGEN DIPL ING
IPC: B01D15/00
Filed: 1977-06-07
Abstract: The mass exchange between solid particles and a liq. or gaseous solvent, e.g. in the prodn. of roasted coffee bean extract, uses an appts. in which a stream of solvent and dispersed solids is sepd. from a stream of solvent by a semipermeable partition which is permeable for the solvent but not for the solids. The solvent is periodically moved forwards and backwards through the semipermeable partition. The relative velocity of the two media can now be set independent of their properties at a very high level. The interface for the mass transport is frequently renewed. The density difference of the two media can be very little and the retention time in the appts. is shortened, resulting in smaller overall dimensions and better profitability.

Title: Control fitment for swivel ends of reclining beds - has single operating unit with spring power acting on both ends
Inventor: HORENKAMP FRANZ
IPC: A47C20/04
Filed: 1977-11-11
Abstract: The swivel-mounted head (2) and foot (3) sections of the bed, couch etc. can be adjusted by setting mechanisms which are mounted on a common stop housing (5). They can be biased in the setting direction by a common power accumulator such as a tension spring (20) which can be connected to the relevant drive members (14) of the articulated chains (6, 7). The setting mechanism at the head can be blocked in various positions by ratchet means (22, 23, 24). Since the two setting mechanisms are combined in one fitment dependent on a single spring, manufacture and assembly costs are low whilst the bed can be fully adjusted by a person reclining on the bed since the head section is automatically raised up by the spring when the ratchets are released.

The lower strut is supported by a base frame whilst the upper strut is connected to lateral connecting elements of the lowe strut. At the upper strut there is a press nip trough which the press belts and the charge to be press-moulded pass. Closed composite frames are arranged along the sides of the press into whose openings upper and lower connectors engage. Between upper and lower struts are cylinder-piston arrangements to which composite frame, upper and lower connectors which define the press nip are clamped. The construction dispenses with a unitary, rigid frame. Upper and lower struts are independent structural components which are coupled together only for functional purposes. This facilitates dismantling and exchanging of wornout parts.

Title: District heating system damage protection circuit - has flow measuring devices connected to central stop valve control unit
Inventor: MEYER JUERGEN DIPL ING
IPC: F17D5/02
Filed: 1978-02-08
Abstract: The circuit provides protection from damage to a district heating system divided by remote-controlled stop valves into separate sections. Measuring devices in each of the sections detect the rate of flow. To detect and locate a fault, successive devices in a pipe, preferably before and after a stop valve, are connected to comparison circuits and, together with threshold-value indicators for further parameters determining the safety of the system, to a central control unit evaluating the input signals. This in turn is connected on the output side to the stop valves and the circulating pumps, so as to initiate shut-off and connection operations in stages.

Title: Greenhouse thermal insulation - flexible plastic combination film along walls being drawn along cross-cords concertina fashion over plants
Inventor: MAYER ANDREAS
IPC: A01G9/22
Filed: 1978-02-11

Title: Motor car compartment filter - with porous non-flammable granules in easily shaped flexible ceramic fibre bag
Inventor: HOELTER HEINZ
IPC: B01D53/34
Filed: 1978-05-05
Abstract: A filter for the absorption of pollutants before they can enter the passenger compartment of motor vehicles or other cabs, uses as the filter medium a non-inflammable granular material of high porosity, such as expanded perlite or clay. This material is packed in a bag with filter capacity, made of non-inflammable fibres (ceramic). If moisture or other noxious substances are to be absorbed, another bag filled with perlite, coated with soda lime or activated carbon, can be arranged in series. This type of filter can be readily adapted to any size of motor car from the smallest to the biggest. No prepns. are required to make the filter insert suitable for individual requirements.
Patent DE-2826808-A1 (DE)
Title: High efficiency cyclone for dust removal from air - has internal conical vessel with ejector inlet deaeration vent from dust hopper and additional vent around clean air outlet
Inventor: OBERMEIER HANS-JOHANN
IPC: B04C5/00
Filed: 1978-06-19
Abstract: Cyclone dust separator separates coarse, medium and very fine dust particles from a dust laden exhaust air or gas stream. The air is injected from a fan at high velocity. The inlet is surrounded by an ejector sleeve which serves to vent the cyclone should excess pressure occur. Dust settles to the base in the normal way but the hopper is vented via a spiral duct which leads via a damper back to the fan inlet. The clean air outlet also has a cylindrical sleeve around it which is vented a valve back to the fan inlet. The inlet ejector has a damper in it also allowing venting back to the fan inlet. In this way, fine particles do not escape. Used for removing dust from gas streams. Gives optimum separation of all particles sizes with compact height of construction.

Title: Releasing sticking coke cake from vertical coke oven - by means of hydraulically actuated pusher heads inserted through charging holes
Inventor: HARTKOPF EDGAR
IPC: C10B33/08
Filed: 1978-07-21
Abstract: A sticking coke cake in a coke oven of the vertical chamber type is released by pusher heads on the piston rods of hydraulic actuators. The heads are introduced through the charging holes in the oven ceiling and exert a downward pressure on the coke as they move down to a point, known to lie below the minimum charge level. This is a less time-consuming operation than trying to find the area where the sticking occurs by gradually removing the coke by poking from the bottom. It saves the additional pollution of the atmos. in the environment during this operation.

Patent DE-2838813-A1 (DE)
Inventor: RAMSBRO BOERJE
IPC: B23H7/28
Filed: 1978-09-06
Abstract: In a method for the electrical discharge machining of metallic workpieces in which an electrode is moved in a rotating translatory manner at right angles to the feed direction in such a way that it assumes a number of positions in succession which are at an identical distance from a centre position, a pulsating return movement in the direction of the centre position is superimposed on the rotating translatory movement in order to effectively prevent short circuits. The stroke of the return movement ( DELTA  epsilon ) can be selected for each working-gap width independently of the size of the eccentric movement, i.e. the planetary or orbital movement, of the electrode itself. The translatory movement is preferably interrupted during the return movement. This can be done by coordination of the drives for the translatory movement and for the return movement in the machine control system. <IMAGE>
