Title: Optical fibre having loose protective sheath - where fibre and sheath have same coefft. of thermal expansion, to avoid microcracks
Inventor: DOUKLIAS NIKOLAOS DIPL PHYS DR
IPC: G02B6/44
Filed: 1975-10-09
Abstract: Optical waveguide fibre (1) has a loosely fitting protective outer sheath (2) around it. Both (1) and (2) materials have the same coefft. of thermal expansion. Material (2) is pref. glass with a lower m.pt. than material (1). Pref. (2) is made by inserting a tubular glass blank in a fibre drawing machine through which (1) is fed, and a capillary sheath (2) is formed around (1). The (1) is not melted during the drawing of (1). Pref. (1) is cooled or screened so it is held below its m.pt. during the drawing of (2). By using a loose sheath and materials (1,2) with the same coefft. of thermal expansion and the resulting microcracking are avoided with a subsequent improvement of optical properties.

Title: Synthetic fibre crimping device - having sensor and thermostat to control action of pressure plate and reduce friction contact times
IPC: D02G1/12
Filed: 1975-11-08
Abstract: Device is used for crimping stands or sliver of synthetic fibres. The material is forced by rollers into a heated compression chamber formed by plates, with a pressure disc and a sensor. In order to keep the pressure plate away from friction contact with the roller faces, the sensor has the effect of pushing the pressure plate intermittently at pre-set intervals against the roller faces and then immediately withdrawing by a micron gap to form an air relief unit. The system ensures that adequate sealing is maintained in the chamber where the material is heated and compressed to give the crimping, but reducing the friction wear on the pressure disc as it is not in constant contact with the rollers.

Title: Test position selector for rotating machinery - has electromagnet operated ratchet for cylindrical reed switch bank
Inventor: ROHRBACH CHRISTOF PROF DR ING
IPC: G01D5/251
Filed: 1975-12-17
Abstract: The test position selector for measurements on rotating machinery consists of a tube (1) which is fixed to the rotating component or its shaft so that it is concentric with the axis of rotation. An electromagnet (4) is mounted on the tube via bearings (2). A ring (6) fitted with a soft iron plate (9) in the vicinity of the electromagnet carries a pawl arm (10). The pawl engages with teeth on a cylinder surrounding the tube (11) and mounted on bearings (12). Movement of the ring is transmitted to the cylinder via the pawl arrangement. At each energising pulse of the electromagnet, the cylinder rotates relative to the position of the tube. A permanent magnet (13) fixed to the cylinder rotates between two rings of reed switches (14) whose contacts are taken out to a circuit board (15) fixed to the tube.

Title: Hot water supply circulating through take off tap - has circulation maintained by injector instead of pump
Inventor: BAELZ HELMUT
IPC: F24D17/00
Filed: 1976-02-14
Abstract: Water from the heater (1) passes to a storage tank (7), and, when no hot water is being drawn off, back to the heater in a circulation which is pref. maintained by a pump (8). To save stagnant water from cooling in the pipe leading to the take-off tap (2), a parallel pipe (9) leads back from the tap to a point near the storage tank: a circulation through these pipes ensures instant hot water at the tap. This circulation would ordinarily be maintained by a second pump, but an injector (11) is to be used instead: the primary flow through the injector is included in the heater-storage tank circuit.

Title: Thyristor controller for charging batteries - has shunt thyristor which short circuits generator when the battery is fully charged
Inventor: HAUBNER GEORG ING GRAD
IPC: H02J7/14
Filed: 1976-07-20
Abstract: The batteries are charged from an a.c. generator through half-wave and full-wave rectifiers. The charge state of a battery is continuously monitored by a measuring device (7) during the no-charge phases, during which a shunt thyristor (3) is under a thyristor controller (5), when the battery charge state corresponds to the required state. The thyristor (3) short circuits the generator at the beginning of the charging half-wave. If the battery is not yet fully charged, the shunt thyristor is kept on, but is blocked by a voltage equal to, or smaller than the battery voltage plus the voltage of a blocking diode (6), thus not shorting the generator during charging half-wave.

Title: Melt-spun filament winding - uses deflection rollers to draw out filaments and pass them back for winding between jet and roller
Inventor: LENK ERICH DR ING
IPC: D01D7/00
Filed: 1976-07-24
Abstract: In a melt spinning assembly, the spun synthetic filaments are drawn by flaoting rollers from the spinning jets and wound by a winding unit. The floating rollers are deflectors at the base of the winding unit on the machine frame. The winding unit is located between the roller and the spinning jet. By deflecting the path of the spun filaments by 180 degrees, there is a satisfactory drawing action and the monitoring is simplified. The height of the winding unit can be reduced by about 25% so that the complete melt spinning machine does not have to be spread over two levels in the building.

IPC: H01J49/14
Filed: 1977-01-14
Abstract: Reaction chamber for the chemical ionisation of atoms and molecules by ion/molecule reactions contains an electrical multiple with >=4 radially symmetrical insulated pole rods to which high-frequency a.c. voltages are applied in turn. The inlets and/or outlets are near the axis of symmetry. The total internal pressure is such that the mean free path of the ions and molecules is smaller than the diametral distance between the poles.

Title: Concrete formwork cross beams coupling piece - has wedge plug twisted to exert two way force
IPC: E04G17/04
Filed: 1977-03-05
Abstract: The device for connecting cross beams in concrete formwork units incorporates a coupling piece for fixture in a beam slit, using plug pieces passing through cutouts in beams and coupling piece. The cross beams (1, 2) have stems (4) spanning the slit (6) and serving as mounting for the coupling piece. One plug piece, at least, is a wedge twisted between beam and coupling piece when in position so as to generate a force acting along the beam length as well as one at right angles to this, striking the coupling piece against the stems. The shape of the cutouts permits rotational movement of the edge about its longitudinal axis while it is being knocked in. This permits accommodation of considerable longitudinal forces, while retaining complete freedom of play in a line at right angles to the formwork plane.

Title: Explosion-resistant pressure vessel composed of concentric spheres - prestressed by radial struts which transmit thrust to innermost pressure shell
Inventor: BORSDORF HEINZ DIPL ING
IPC: G21C9/00
Filed: 1977-07-14
Abstract: Anti-burst pressure vessel for nuclear reactors and chemical plant comprises an initially unstressed, inner vessel surrounded concentrically by a number of successively larger vessels. Radial struts between successive vessels are expanded radially, thus prestressing the tension elements of each of the surrounding vessels. Thus all the vessels, each of which is generally spherical, transmit radial forces inwards onto the initially unstressed innermost pressure vessel. Each surrounding vessel is composed of panels with joints between them, generally constituting a honeycomb pattern. The joints are so shaped that they stabilise the vessel form. The vessel possesses tension elements, partic. prestressing cables which are all stressed together by the radial outwards thrust of the struts. Arrangement gives high resistance to explosion pressures, partic. due to the elastic yielding capacity of the vessels, which tend to operate as a safety valve. The prestressing action provides a tight gas seal at the contact joint between the panel elements of the separate spheres. The system also makes use of the increased resistance provided by a number of successive vessels as compared with a single, rigid vessel.
