Patent DE-2855206-A1 (DE)
Title: Agitator element with variable effective diameter - having hinged flights with steps giving different effective dia. depending on direction of rotation for insertion through limited openings
Inventor: HOELZ OTTO
IPC: A01C3/02
Filed: 1978-12-21
Abstract: Agitator has a circular plate mounted on a vertical shaft. Attached to this plate are a series of blades, pivotted on arms. These arms can move in towards the centre or outwards depending on which face of the blade, pressure is applied. Effective dia. of the agitator element changes depending on the direction of rotation of the shaft. It allows the agitator to be inserted through a relatively small opening and then to operate as a larger dia. unit. Used on effluent pits and tanks. Where these are constructed with reinforced concrete covers, the unit allows an agitator to be inserted through a relatively small opening but operate as a much larger one. This gives the improved agitation associated with large units without the expensive modifications needed to alter a reinforced concrete lid.

Title: Line flyback pulse signal for TV receiver - is generated using separate winding on picture width setting choke
IPC: H04N3/22
Filed: 1979-12-20
Abstract: Impulses (14) in synchronism with the line reset signals applied to the line deflector coils (8) are derived from a second winding (12) on the variable choke (10) in the picture width control circuit. By obtaining the impulses in this manner a second winding on the line transformer is avoided. The transformer can be designed specifically for its main duty. Any increase in leakage flux due to added windings is avoided, and distorting harmonics eliminated. In addition to its use as a synchronising signal for the line scan, the reset impulse can also be applied to a fault detection system. If the pulse amplitude departs from normal, ie if it becomes too high signifying an excessive current due to high power supply voltage (+U1), the protective circuit.

Title: Hardness level sensor for water softener - has ion-exchanging shrinking resin regenerated by saline soln. with piston detecting level of top surface
Inventor: SPIEGL KARL
IPC: B01J49/85
Filed: 1979-03-20
Abstract: A hardness grade sensor is for water softeners. It contains an ion-exchanging shrinking resin and can be regenerated by a saline soln. A free upper surface of the resin filling essentially lying in one plane, but changeable in position, is used as a measure of the exhaustion of the softener. The surface is physically scanned to this end. A piston floats on top of the resin filling. This piston is adjustable in height by shrinkage and expansion of the resin but in the opposite sense. A spring can be installed whose return force opposes the power of expansion of the resin filling. This spring can engage the piston. The latter can be conical to compress the filling. It can have a sharp scrapping edge on the side facing the filling.

Title: Improving blood access to dialysis hollow fibre bundles - by compressing ends during setting of retaining plastic block
Inventor: SIGDELL JAN-ERIK DR
IPC: B29C39/00
Filed: 1980-02-09
Abstract: The ends of a bundle of hollow plastic fibres which are embedded in a cast block of plastic which is then cut to open up the fibre ends are compressed after this block is formed but before it has set. The compression can be effected by (a) a plastic sleeve which shrinks at the temps. produced by the setting plastic, (b) clamping jaws, (c) a loop of wire or strip which is tightened during the setting. With method (c) the loop is wound on to a bar, and is initially loose so that tightening only begins after a certain delay, and a stop may be provided so that the loop eventually breaks under further tightening. While the fibres used in dialysis or blood filters must have their ends initially sepd. enough to allow access to the retaining plastic, in the finished bundle this should be closer together to give more effective blood access, while most of their lengths remain more widely spaced to improve dialysate access.
