Title: Internally supported rollers for conveyor belt train - have plastics bases and metal bearing mounts and plastics metal carrier tube
Inventor: VAHLE KLAUS-HEINRICH
IPC: B65G39/09
Filed: 1977-04-05
Abstract: Internally supported rollers for a conveyer belt train have plastics bases and metal bearing mounts fo receiving the roller bearings or seals, as well as a metal carrier tube onto the outer surface of which plastics coating is cast serving as running layer. The carrier tube is a normal, uncalibrated piece of tubing, and the casting mould is designed so that when the plastics layer is cast on its outside, the front and inner surfaces of the tubing and both seating surfaces for the roller bases are also coated. As a result, the surface of the plastics applied onto the ends and inside of the tubing double as snug fit and buffer for the roller bases. The rollers are mfd. economically since there is no need to use a calibrate tubing.

Title: Leak monitor for long pipeline - has enclosing condenser strip with capacity altered by fault to initiate alarm
Inventor: BAUM HERBERT FRIEDRICH ERNST I
IPC: G01M3/18
Filed: 1977-06-03
Abstract: The system gives permanent monitoring for leaks and of the insulation of long pipelines under pressure, showing faults and their positions in a central control station. The pipeline is insulated by a strip-type condenser which forms the monitoring unit. The strip is of any desired length and of material capable of stretching, with high resistance to tearing and good dielectric characteristics. A number of embedded perforated and fully insulated metal foil strips form the condenser fins. The strip forms a closed sleeve totally enclosing the pipeline, so that any fault such as a leak or break inside the condenser and any action from outside affects the fins and thus the capacity, initiating an alarm.

Title: Limit voltage stabilisation circuit - applies limit voltage to emitter of transistor whose collector is connected to amplifier controlling its base
Inventor: REHFELDT KARL-HEINZ DIPL ING
IPC: H04N5/16
Filed: 1977-10-18

Title: Radio communications system using narrow-band signals - sends signals at various frequencies simultaneously to increase waveband usage
Inventor: BOEHM MANFRED DR ING
IPC: H04J1/14
Filed: 1977-11-11
Abstract: The radio communications system allows additional messages to be sent in frequency bands already occupied and to do so without interfering with existing traffic. This is accomplished by emitting several narrow-band signals of different frequencies consecutively or simultaneously. The frequency spacing between these signals is large compared to their bandwidth. Each signal contains a part of the message being sent. Several messages can be sent simultaneously if some of these signals are brought together into groups.

Title: Multiple contact electric switch - has contact supported bridge connected to outer terminal via conductive path, independently of switch position
Inventor: SWANN DAVID ALLEN
IPC: H01H23/12
Filed: 1977-12-16
Abstract: The design is suitable both for rotary and slide switches. The switch contacts lie in a direction, along which a contact bridge (40) can move. At least one contact forms a support bearing for the bridge. When the latter is moved from a first contacting position into a second one, it tilts on the support bearing. This bridge tilt breaks the first contacting position and effect another one. During the movement the bridge is connected to an external terminal (21), connecting fin etc. independently of its switching position, via a conductive path (102, 104, 503). Preferably the external terminal serves also one of the contacts (21-24).

Title: Gadolinium oxide luminophore activated with bismuth - produces visible light when excited by ultraviolet or X=rays, used in fluorescent screens
Inventor: DEGENHARDT HEINZ DR RER NAT
IPC: C09K11/78
Filed: 1978-02-13
Abstract: The luminophore consists of Gd2O3 which is activated by 0.1-1 atomic % Bi, esp. 0.3 atomic % Bi to obtain Gd2O3:Bi. The pref. luminophore is made using a mixt. of 361-8 g Gd2O3 with 4.66 g Bi2O3, plus 36 g Na2B4O7 used as a flux. This mixt. (1) is milled for 12 hours in a ball mill; heated 1 hour at 1100 degrees C; crushed; and sieved, esp. using a sieve with 35 mu m mesh width. The Na2B4O7 may form 1-20Wt% of the mixt. As compared with other luminophors, only a relatively small amt. of an inexpensive activator, viz. Bi, is required, so the cost of the luminophore is reduced; and bright white light is obtd. when the luminophore is exited by ultraviolet rays.

Title: Power station flue gas filter - consists of soil layers absorbing toxic components
Inventor: HOELTER HEINZ
IPC: B01D53/68
Filed: 1978-03-04
Abstract: The flue gases from thermal power stations which leave at a temp. of 140-180 degrees C are first freed of chlorides and dust in a scrubber. The residual contents of SO2, NOX, HF and other toxic substances are removed by a biological soil, filter. This filter consists of alkaline layers of soil which pref. have been made less compact by admixtures of humus, compost, peat, straw, sawdust or wood shavings. These additions have phosphate, dibasic carboxylic acid and N contg. material added to them, and the filter is impregnated with cultures. Absorptive or porous materials such as expanded clay or perlite may also be added. This ensures that the contaminants are adsorbed and retained by the soil filter and that environmental pollution is prevented.

Title: Thickness measurement of cylindrical objects, wire etc. - by determining attenuation of parallel light beam passing through measurement vol. via rectangular aperture and lens
Inventor: SCHULZ WOLFGANG DIPL PHYS DR I
IPC: G01B11/10
Filed: 1978-04-28
Abstract: A device measuring the thickness or dia. of wires, threads, fibres and cylindrical objects of approx. circular cross-section uses a photodetector determining attenuation of a parallel beam. It achieves a measurement accuracy of 0.1 per cent. A parallel light beam passing through the measurement vol is limited by an approx. rectangular aperture from which it passes to the detector via a lens. The detector output is compared with that of a detector receiving a reference part of the beam in an amplifier used to regulate the light source power to give a defined reference intensity.

Title: Fibre web impregnation process to mfr. plastic tubes - comprises laying fluid over fibre surface and pressing some of it into fibre, leaving surface layer to be pressed in later (NL 29.1.79)
Inventor: MAGARIAN GERALD MALCOLM
IPC: D04H1/64
Filed: 1978-07-25
Abstract: The distributed fluid is applied vertically to the fibre material or across its surface, and is pressed into the fibres by a moving converging surface pressing against the material. The converging surface has a number of smooth projections at the same spacing from the material to form the smooth fluid layer of uniform thickness on the surface of the fibre material, ranging in the direction of fibre material movement. To develop a plastic tubing, a powered rotary mandrel is used to apply the fluid resin and distribute it across the width of the fibre material. The same process can be used on a glass fibre matting to be used as a reinforcing layer in the construction of a plastic tubing. The process allows fibre material of a sensitive character to be impregnated fully with a resin, at high speeds, and without damaging the fibres.
