Patent DE-1951667-A1 (DE)
Title: Slide fastener thermoplastics wire coiler
Inventor: OTTO GALONSKA WALTER
IPC: H04N19/423
Filed: 1969-10-14
Abstract: Wire lengths reeled off a stock spool re passed to an axis bar and so to the mandrel at the far end of this. This bar has a drive rotor with coupling arms and a coiling rotor at the far end together with dogs for the wire, one with an eyelet and the other as a tube to guide the wire in and through onto the coiling mandrel. This coiling rotor is designed in terms of mass to act as a differential gearing to ensure that the wire reels off in tension and onto the mandrel in tension to prevent twisting. A brake allocated to the coiling rotor is controlled by an electric regulator to ensure that the coiling rotor is always one wire length ahead of the spool and that this amount is wound each time onto the mandrel.

Title: Yarn monitor - for spinning/twisting with sensor travelling on cleaning unit with electro-magnetic triggering
Inventor: SYRISTE RUDOLF
IPC: D01H13/14
Filed: 1971-06-12
Abstract: Travelling with the suction cleaning unit, the sensor on its swing arm monitors the state of the yarn and, on a breakage, allows the arm to trigger a micro-switch to operate a rotary magnet. An arm on the magnet lifts a switching rail, representing a run of 10-20 spindles, to close a micro-switch circuit and illuminate a warning lamp for that spindle sector. This provides a simple and versatile yarn monitor which can be mounted on a variety of spinning and twisting machines without equipment modification.

Patent DE-2232340-A1 (DE)
Title: Counting particles in suspensions - by automatic control circuit
Inventor: GOEHDE WOLFGANG DR
IPC: G01N15/14
Filed: 1972-07-01
Abstract: The suspended particles modify the electrical field between two electrodes, causing signals to pass to a counter. The suspension flows past one electrode to two probes, between which the gap defines the unit volume for measurement of particles. The probes, a system of three valves and a vacuum pump are connected to a control circuit by means of which the suspension fills the gap between the probes while counting takes place, and then discharges the unit volume. This completes the automatic cycle, which can be repeated rapidly if required.

Title: Ion exchange bed pretreated for uniformity - then covered with buffer layer to prevent leakage paths developing through bed
Inventor: SCHAFFERUS HANS
IPC: B01J47/00
Filed: 1973-07-03
Abstract: A method of treating ion exchange bed material comprises: the bed material is treated, before being brought into use, with ions of a single specific type, until no further change occurs in the ions concn. after they have passed through the bed; the bed material is thus present in a single, specific form of charge. After this, the exchange material is washed out with completely deminieralised or distilled water and simultaneously or subsequently flooded to permit free movement and resettling of the particles according to their size; after they have settle, a buffer material is introduced above the bed material.

Abstract: The switching off circuit for a power transistor has a tapped choke connected at one end to the power transistor control current, at the other end over diodes to the power transistor emitter circuit, and at its tapping directly to the base of the power transistor. When on, the power transistor receives its base current from one h alf of the choke. When the control current is switched off, the energy stored in the second half of the choke, i.e. the half not in the control circuit, is passed to the transistor base-emitter barrier layer such that the power transistor base current reverses in direction.

IPC: C01B13/10
Filed: 1974-07-09
Abstract: Stabilisation of ozone to form a reactive oxidising agent, e.g. for sterilising water in swimming pools, is effected by mixng an ozone-contg. gas with a soln. of a stabilising cpd.
