Title: Electronic thread breakage detector - uses capacitor charge time as parameter for thread speed and cut-off delay
Inventor: GITH WALTER
IPC: B65H63/06
Filed: 1976-01-27
Abstract: An electronic thread breakage detector cuts off a textile machine whenever a set response parameter is not maintained for a certain period. The cut-off time is varied inversely proportional to the thread speed. The instantaneous charge of a capacitor is used as a parameter for the thread speed. The time required for an additional charge of the capacitor up to a set value is used as a parameter for the cut-off time. This prevents malfunction of the detector at very slow thread speeds when the stored energy is so small that a broken thread may be erroneously simulated.

Inventor: ZIMMERMANN ERICH
IPC: H02G15/22
Filed: 1976-04-14
Abstract: The end closure is intended for a cable installation having coolant, especially water, which is guided in the circuit for internal cooling of the conductor. The re-preparation of the coolant takes place in an installation which is at earth potential. A fluid insulating path is arranged between the high-voltage potential and earth potential. In order to ensure temperature limiting of the cooling fluid within the insulating path, which is used for potential bridging, even in the event of a disturbance and when the main circuit is stationary, the fluid insulating path for the coolant from the longitudinal channel (2) of the conductor (1) (main circuit) is allocated a further fluid insulating path, including an auxiliary circuit, which is at earth potential, for a coolant. In general, water is recommended as the coolant for both circuits. <IMAGE>

Title: Thermal deaeration device for turbine condensate - simplified by screen over spray head in feedwater tank
Inventor: BRUENING ROLF
IPC: C02F1/20
Filed: 1976-06-02
Abstract: Turbine condensate is thermally deaerated in a spray nozzle system with sieve. Heating steam is introduced below water level. The nozzle system includes a spray head with radial bores, surmounted by a screen. A tubular sieve inside the cylinder forms an annulus from which impurities can be discharged periodically through a pipe. The strained water enters a spray head with several rows of holes to produce water jets. A screen surmounts the spray head. Heating steam is introduced through a distributor below water level in the feedwater tank. The screen has the shape of a truncated cone, is welded at its top edge to a vertical inlet pipe. Its bottom edge lies in the same plane as the upper row of bores for the spray head. This simplifies the design of th deaeration device on the feedwater tank and improves the discharge of the not condensible gases.

Inventor: SEIDLER HELMUT DIPL CHEM DR
IPC: C07C/
Filed: 1976-12-02
Abstract: The prepn. of chloroanthraquinones involves the passage of Cl2 into molten mono- and/or di-nitroanthraquinones, at 160-280 degrees C. The chlorination appts. can be a bubble column in >=1 stage, or a container equipped with a stirring system. The process can be continuous or discontinuous. The chloroanthraquinones formed in the molten state are then removed from the appts. The chloroanthraquinones are used in the prodn. of vat dyes, or dyes for wool. Compared with previous processes, this process does not require the use of a diluent; it gives high yields of chloroanthraquinones and to a certain extent improves their degree of purity.

Title: Insulating coatings for flexible printed circuits - of UV- or electron beam curing lacquers
Inventor: REESE ECKART DR
IPC: H05K1/00
Filed: 1977-01-04
Abstract: Flexible printed circuits and wiring units consisting of a carrier of reinforced or non-reinforced plastics with a series of metallic conductor leads bonded to it, are provided with an insulating covering consisting of a UV - or electron beam curable lacquer. The UV-or electron beam curing lacquers are used to replace the adhesive-bonded overlay films currently used as insulating coatings on flexible printed circuits, which latter must be applied underr controlled climatic conditions to obtain the required sealing properties from the adhesive. The UV- and electron beam curing lacquers are easy to apply and are suitable for large scale prodn. processes. They give coatings with excellent mechanical and electrical properties, heat resistance (e.g. during soldering at 260 degrees C) and flexibility. The coating can be applied. e.g. by screen printing. The printed circuits re made in the known way on carriers such as fibre reinforced phenolic- or epoxy resins and films of polyester, polycarbonate, polyhydantoin, polymide or polysulphone resins.

Title: Template tracer with monitoring and movement control - to hold feeler against template outline without using magnetic grip on template
Inventor: LAWS ARTHUR ERNEST
IPC: B23Q35/124
Filed: 1977-02-07
Abstract: The mechanism to register and follow the outlines of a template has control systems to trace the outline of the template and trace its contours. The registering system brings the feeler into contact with the template, with movement control, and monitoring to determine the movement of the feeler. The monitoring mechanism controls the movement system so that the feeler is moved across the line which the feeler follows in the relative motion between the feeler and the outline of the template. The system does not use magnetism to hold the feeler against the template, so the construction of the template can be simplified by using a plastic or similar cheap material.

Title: Electrical sensing circuitry for particle analyzer - has feedback linking power and sensing electrodes to eliminate electrolyte conductivity effects
Inventor: HOGG WALTER ROBERT
IPC: G01R27/26
Filed: 1977-03-11
Abstract: The particle analyser has a microscopic aperture-defined sensing zone separating two bodies of electrolyte and particles in the electrolyte are caused to pass through the sensing zone. A first pair of sensing electrodes and a second pair of power electrodes are positioned with one electrode of each pair being on opposite sides of the aperture. A feedback circuit measures the contstant DC voltage component between the sensing electrodes and feeds same back to the power electrodes, to cause the analyser to be independent of power electrode polarisation. The connections to the sensing electrodes permit only negligible current to flow in them and thereby minimise their polarisation.
