Patent DE-2640336-A1 (DE)
Title: Improving the chilling effect on spun filaments - by directing air upwards towards spinneret and diverting flow sideways
Inventor: MITTENZWEI ROLF
IPC: D01D5/04
Filed: 1976-09-08
Abstract: A device for improving the cooling effect on freshly spun filaments of synthetic high polymer cpds., produced by the melt spinning process, esp. for freezing profiles or crystalline structures, superimposes upon the commonly used transverse air flow, a current originating in the zone of the filaments and directed vertically upwards which is deflected radially close to the extrusion nozzle. Beneath the spinning nozzle, inside a cylindrical housing which can be subjected to suction a suction slot is formed which diminishes in size upwards in the direction of the suction outlet. To effect this, an air guiding ring with an inclined rim, which can be adjusted in its height, together with a ring plate are fitted. Alters the direction of the air flow in the zone of the filaments, so that the point at which an increased extraction of heat takes place, is moved considerably nearer the spinning nozzle.

Title: Anodic corrosion protection of metal objects - with potential scanner applying auxiliary current source when potential discrepancies exist
Inventor: STACENKO NIKOLAJ NIKOLAEVITSCH
IPC: C23F13/00
Filed: 1976-09-20
Abstract: Anodic protection. against corrosion for metal objects in the chemical, food, textile and cellulose/paper industry which are in contact with aggressive media is based on potential regulators which are connected via a controlled switch with their positive poles to the objects and with their negative poles to cathodes. A reference electrode feeds the input of each regulator. An additional reference electrode near each object is periodically scanned, and a potentiometer connected to it applies an auxiliary current source to the object if the potential differs from a set value. This avoids corrosion during repair or maintenance periods or during faults in the potential regulators or sudden increases of the aggressivity of the corrosive medium. It provides for an individual protection of each object if several of them are connected up.

Title: Back-flushing multiple basket water filter - having double seating valves to backflush each basket with clean water
Inventor: VOELKER KARL
IPC: B01D29/00
Filed: 1976-12-23
Abstract: Filtration of liquid media esp. water for household or other use, uses basket filter elements mounted in a housing. There are >=2 such elements with filter meshes on support. Down the centre of each is a rod with valve elements on either end so designed that the upper or lower circular opening to the basket can be closed by moving the rod up or down. Normally, the upper opening is free so that water enters from the top and deposits suspended material on the filter surface. The element is backflushed by pushing down the rod, sealing the top opening and opening the bottom one. Water from the clean side then passes back through the element, removing debris and passes out of the bottom opening which discharges into a collection space. This has a run off outlet. Used esp. in water purificn. plants. Allows in line filtration with element cleaning without the need for taking off stream. Continuous supply of filtered water is assured.

The unit may be equipped with roller attachments for acetate rolls.
Patent DE-2701012-A1 (DE)
Title: Stopper for centrifuging bottle esp. for blood serum - automatically dispenses granules necessary for separating serum from blood
Inventor: WOENNE KARL-GEORG
IPC: B01L3/14
Filed: 1977-01-12
Abstract: A stopper for a centrifuging bottle, esp. for the separation of serum from blood, automatically dispenses a predetermined amount of beads or granules of solid matter into the bottle. At its upper end it is a normally closed stopper and it contains the solid matter in an inner chamber with a seal at the bottom. When a predetermined speed of revolution has been reached, the centrifugal force opens the seal and the solid matter is emptied. The sealing force of the hinged bottom cover is set at a predetermined value. The inner chamber contains a synthetic granulate serving as a centrifuging auxiliary, in a quantity of about 0.5 g and with a particle size of 2-3mm. The closing force of the seal is equiv. to a centrifugal force acting at about 1,500 r.p.m in a machine for separating serum. When opened the seal is still retained by the stopper, the closing force being derived from its resilience.

Title: Readily mounted shower curtain and support fixtures - include adjustable clamps for attachment to fixed vertical rod
Inventor: STUEHMER ROLF HERBERT
IPC: A47K3/38
Filed: 1977-05-16
Abstract: The curtain rail is attached to a locally fixed anchorage point by a support element (16) with a pair of clamping jaws (18, 20). These clamp round a vertical locally fixed support rod (14) e.g. the shower pipe. One of the clamping jaws (18) is firstly connected to the support element (16) whilst the second clamping jaw (20) can be moved away from the first jaw until the two jaws can be closed round the support rod. The length of the clamping face formed by the clamping jaws measured in the direction of the support rod is great enough to take up the force which could be exterted on the support rail (2) and support element (16) during use of the shower curtain (4). A single hand-operated clamping screw can be used to exert the clamping force between the two clamping jaws.

Title: Rotating motor with linear motion output - having hollow shaft with female thread and rod with mating thread
Inventor: KUEHNLEIN HANS DIPL PHYS
IPC: H02K7/06
Filed: 1977-09-29
Abstract: The motor shaft (13) is hollow. Over at least a part of its bore length it has a female thread (14). Engaging with this thread is a corresponding mating thread (15) on the driving rod (16). If rotation of the rod is prevented, then, when the motor runs, the rod will be moved axially, the direction depending upon the motor rotation. With a drive of this type the bearings can be placed well inside the motor active length thus giving a shorter overall machine. The fixture of the rod can be part of the motor housing.
