Title: High purity glass objects, esp. optical waveguide fibres - made by CVD of two glass layers of mandrel using flame hydrolysis burner, then removing mandrel and collapsing layers by heating
Inventor: BLANKENSHIP MICHAEL GREGG
IPC: C03C13/04
Filed: 1979-09-21
Abstract: This is an addn. to 2827303, and describes the mfr. of glass objects by flame hydrolysis, using a mandrel onto which two layers of glass particles are deposited. The outer, layer has a lower refractive index than the inner layer. The mandrel is removed, and the layers are heated (I) to consolidate the glass and to close the hole left by the mandrel. At temp. (I), the underlayer has viscosity(V1), and the top layer has viscosity (V2), where V1/V2 is smaller than 1/2, but large enough to prevent the inner layer sepg. from the outer layer coating. The blank is then made into the desired object by the method described in 2827303. Economic mfr. of fibres provides waveguides with high numerical aperture, e.g. 0.24.

Title: Prepn. of purest rubidium-81 for medicinal use - by irradiating krypton and protons or deuterons, electromagnetic isotope sepn. and implanting rubidium-81 in common salt
Inventor: HANSER ALBRECHT DR
IPC: B01D59/44
Filed: 1979-09-28
Abstract: Prepn. of Rb-81 suitable for medical purposes comprises producing Rb-81 by chain reactions and then sepg. the impurities using an electromagnetic isotope sepn. (16) and then implanting the sepd. Rb-81 atoms in common salt. Auxiliary appts. for carrying out this prepn. is also claimed. It comprises a gas target chamber (3) in which the chain reactions can be carried out, and which can be inserted into the ion source (15) of the electromagnetic isotope separator (16). There is very low loss of surface ionisation in the hollow chamber. The Rb-activity produced after irradiation of krypton collects on the cylindrical walls of the gas-target chamber. The radioisotope obtd. is practically free from all radioactive impurities. Final stages of prepn. are simple. Common salt is easily dissolved in water and therefore produces (together with the homogeneously distributed Rb-81 in milli curie amts), a physiological soln. suitable e.g. for injections.

Title: Continuous strip electroplating appts. - in which strip is turned about its longitudinal axis to achieve more uniform plating
Inventor: JENNIGES NORBERT
IPC: C25D7/06
Filed: 1979-11-24
Abstract: A continuous metal strip electroplating device consists of a tank which contains two anode boxes at its sides and spaced sink rolls above its bottom. Above the tank and along its centreline is a device for reversing the direction of the strip together with a coiler and decoiler. The improvement is that the strip is turned about its longitudinal axis (pref. by an angle of 45-135 deg.) during its passage between the sink rolls and the direction- reversing device. This is pref. achieved by inclining the sink rolls at about 45 deg. to the centreline of the direction-reversing device. The appts. is useful for nickel plating steel strip for use in Ni-Cd accumulators. The invention avoids preferential nickel plating at the strip edges so that the plating thickness only varies from 0.8 to 1.1 microns compared with from 0.66 to 1.5 microns for appts. This allows higher current densities to be used.

Title: Control device for quality of incandescent wires - uses three roller system with difference in force on two outer rollers measured by balance weight, spring extension on bridge strain gauge
Inventor: KOERBER KURT DR ING
IPC: G01N3/28
Filed: 1979-12-24
Abstract: Incandescent wires are mnfd. by continuous drawing. A roller system, consisting of three rollers (1) in the same plane are fitted in a housing (2), the wire passing sinusoidally over the rollers. The tension in the wires is measured by measuring the difference (delta. S)=S(1)-S(O) between the horizontal forces S(O) and S(1) on the first and last rollers, this force being measured by the aid of a spring, a flexible beam or a pendulum. The spring uses the extension as a measurement of the firce difference, the flexible beam uses a strain gauge and the pendulum uses a balancing weight. The most sensitive detection method is based on the strain gauge elements which are connected in a balance in conjunction with an operational and a measurement amplifier, the precise balance being strained by a potentiometer.

Title: Filter which separates pilot frequency from carrier wave - by adding two phase shifted signals obtained by demodulation at zero phase and 90-degree phase
Inventor: GIROLAMI GIORGIO
IPC: H04J1/14
Filed: 1980-01-31
Abstract: The filter produces an interference frequency Fm roughly equal to Fp + DELTA F, where Fp is the pilot frequency and DELTA F = Fs + Fp where Fs is the sideband transmission frequency. Two waves shifted in phase by 90 deg. are derived from the interference frequency. Demodulation is accomplished for the 0 deg. phase wave and for the 90 deg. phase wave. The two signals obtained from these two demodulation processes are shifted by 90 deg. w.r.t. one another and added. The signal of frequency DELTA F is filtered from this sum. The system comprises an oscillator, two demodulators, a phase shifter, a summation circuit and a filtering circuit.

Title: Reduction of harmonic currents in AC for rectifier - by incorporating HF chopper between rectifier and DC output
Inventor: HIRSCHMANN WALTER
IPC: H02M1/42
Filed: 1980-07-04
Abstract: The proposed rectifier circuit reduces harmonic disturbance on the a.c. feed to the rectifier without the addition of external filtering or compensation. The incoming supply (1) is rectified (2) and applied to a storage capacitor (4) through a smoothing reactor (3). The resulting d.c. voltage (UH) is applied to a chopper, e.g. an oscillator or similar device (6,7,8) pulsed from an external source (12). The pulses are of fixed mark to space ratio at a fixed repetition rate which is short w.r.t. the mains frequency. The d.c. output (Ua) is taken from a smoothing capacitor (9) on the chopper output terminals. For an output to intermediate direct voltage ratio (Ua/UH) greater than the chopper mark to space ratio an input a.c. waveform approaching the sinusoidal is achieved. The chopping frequency is typically 20-25 kHz.

Title: Textile machine dust removal - has collecting sack at end to take dust from mobile cleaning units
Inventor: GEIST HERMANN
IPC: B08B15/00
Filed: 1980-12-19
Abstract: An exchangeable dust sack is placed at the end of the textile machine, in a funnel-shaped housing, to take dust collected from the mobile blowing/suction unit to remove dust and debris from the working stations. The funnel-shaped housing, the dust sack or the dust collection chamber in the mobile unit are held at a light underpressure. A low underpressure is maintained, to create a light vacuum, to ensure positive transfer of dust to the collection sack from the dust collection chambers. This is done during the whole machine operating time, or during planned time phases for dust clearance. The system gives a simple dust removal process, partic. for a textile machine with a central air suction and blowing supply.

Title: Clamping device
Inventor: BAKER GEORGE EDWARD
IPC: B23H7/26
Filed: 1981-05-16
Abstract: An element, such as, for example, an electrode (10), to be held in a clamping manner by a clamping device (13, 15), passes in a sliding manner through the interior of a rigid tube (19), one area of which is arranged in a fluid chamber (17) which is defined by a body (16) of the clamping device (13, 15).
