Title: Electron beam butt welding - using filler strap in and/or over butt joint gap
Inventor: SUZUKI MUNENOBU
IPC: B23K15/00
Filed: 1974-05-15
Abstract: To join two abutting metal plates by electron beam welding, a bar of a filler metal is laid over a gap at the butt joint. The electron beam is directed on top of this bar so that it melts and fills the gap. The gap is so dimensioned that the molten metal just fills it. The gap can be partly filled up by a filler metal insert or powder prior to welding. A copper backing plate can be used at the other side of the joint. This eliminates welding defects (unilateral fusion, arching) which are common in conventional electron beam welding. A simple electron gun is suitable for this method. The butt joint requires no careful preparation and can be flame cut.

Title: Broad band oscillator for microwave operation - with protection against parasitic inductance additional capacitance between base and ground
Inventor: SUNKLER ANTON DIPL ING
IPC: H03B1/00
Filed: 1974-08-28
Abstract: A broad band transistor oscillator for operation in the micro-wave range is designed for stable operation and it is insensitive to the effects of parasitic inductance. The oscillator transistor has a given capacitance connected between the base and the collector (CcB) and an additional capacitance (CBM) is coupled between the base and earth in series. Due to the additional capacitance (CBM) the effective circuit capacitance is reduced and the operating frequency increased. In addition the influence of te additional capacitance results in a high frequency earthing of the base that generally eliminates the effects of parasitic inductance.

Title: Pulse modulator for radar transmitters - has chain of ccts. charged separately and discharged to give output pulses of specified length
Inventor: FRANKE HANS-JOACHIM
IPC: H03K3/57
Filed: 1974-09-21
Abstract: The pulse modulator chain, for radar transmitters, has a chain of circuits charged separately to produce pulses of predetermined length. The discharge pulses from these circuits are passed to the modulator's output sequentially to give the required output length pulses. The number of circuits in the chain is equal to the maximum number of output pulses. The circuit chain is served by two charging circuits coupled to it over diodes and containing thyristors whose triggering determines the lengths of the output pulses. The advantage lies in being able to generate pulses of different durations.

Title: Earth-fault sensor with sync. detector - has oper. amplif. coupled to diff. transformer making cut-out point independ. of line capacitance
Inventor: CLARK WILLIAM R
IPC: H02H3/33
Filed: 1975-02-28
Abstract: The earth-fault sensor with sync. detector has a differential transformer coupled into the two lines with its secondary winding across the inputs of an operational amplifier acting both as an amplifier and as a phase-sensitive demodulator. The amplifier only produces an output when one of its inputs has a pre-determined polarity and therefore only operates the circuit breaker when this condition is met. In this way the breaker's trigger point is not affected by the line's capacitance to earth. The transformer's two primaries are coupled as follows: one into the earth line and one into the 'live' line.

Title: Ribbon fabric prodn. - by longitudinal cutting of wide fabric with cutter-welder
Inventor: PASTORELLI DANTE
IPC: D03J1/08
Filed: 1975-05-05
Abstract: Ribbons e.g. for labels, trimmings etc. are produced starting from a single woven fabric obtd. on any type of loom, by subjecting the fabric to a multiple cutting-welding operation in the longitudinal direction, downstream from the loom, after having reduced vibrations and transverse tensions in the fabric but before winding it up on bobbins. Pref.longitudinal tensions are regulated by standardised friction. Method enables a much reduced number of shuttles to be used and therefore a wider range of colours or yarns of different type and gives better loom utilisation as well as permitting ribbon width to be changed easily.
Patent DE-2520096-A1 (DE)
Title: Rubber cushioning rings for motor vibration damping - are mounted on axles of supporting belt for ventilator
Inventor: KRAEMER HANS GEORG
IPC: F16F1/373
Filed: 1975-05-06
Abstract: The purpose of the device is to cut down vibration propagation from motors and other source and prevent disturbance of surrounding equipment. Ventilation vibrations are particularly troublesome and are cushioned by circular rubber rings in the supports providing axial and radial stability in the outer bearing and housing. One shoulder of the axle lies against the rubber ring which improves the axial damping. The rubber ring is deformed by squashing it inside the bearing housing, producing more forceful opposition to further vibrating deformations. The ventilator fan is indirectly belt driven through motor (3) and is supported on a column (5) on top of metal bands (4) resting on the rubber cushioned axles (7).
Patent DE-2520396-A1 (DE)
Title: Primary coolant pump emergency seal for boiling water reactor - has axially sliding ring operated by compressed air
Inventor: LILEG JOHANN ING
IPC: F04D29/14
Filed: 1975-05-07
Abstract: A sealing device for a primary coolant pump, esp. of a boiling water reactor, is brought into action by an actuator ring if the pump is shut down or the shaft seal fails. This actuator ring is mounted between the pump casing and the shaft and/or a shaft ring surrounding the shaft. An inwardly projection collar flange of the actuator ring carries a sealing element such as on O-ring, which comes into contact with the counter-surface to form the seal, when the actuator ring is displaced axially. The counter-surface is pref. formed by a ring having a conical surface towards the shafts axis and fixed in the shaft ring. The actuator ring is pref. normally held by a spring force in its inactive position, so that the seal is open, and can be closely by supplying compressed air through a connection into a conical gap existing between the pump casing and the actuator ring; this displaces the actuator ring axially like a piston and closes the seal. During normal running, no accidental contact occurs at the seal. Nevertheless, the seal can be rapidly and completely closed when desired.

Title: Raster correction for videophone document transmission - compensates for trapezium distortion by passing scan waveforms through transducer
Inventor: SCHNEIDER ADOLF DIPL ING
IPC: H04N1/10
Filed: 1975-05-27
Abstract: The raster correction device for the transmission of documents via a video-telephone, is designed to eliminate trapezoidal distortion of the image due to asymmetrical scanning. Since an angled mirror has to be used to transfer an image of a document lying horizontally at the foot of the instrument to the pick-up tube, the scanning beams do not meet the plane of the document at right-angles but at an angle (d) to the vertical. A trapezium- shaped image results. To compensate for this, the amplitude of the horizontal deflection sawtooth waveform is made to increase and decrease in step with the rise and fall of the sawtooth waveform of the vertical deflection signal. This can be effected by passing the scanning waveforms through a control amplifier or by the use of a transductor.

Title: Continuous activated sludge sewage treatment - with breakdown of soluble nitrates by bacteria in oxygen-deficient zone
Inventor: RONGVED PAUL INGOLF
IPC: C02F3/30
Filed: 1975-07-11
Abstract: Raw liq. sewage is injected into a reservoir which provides a single horizontal closed llop path. The liq. circulates at a minimum speed of 0.8 ft/sec. to prevent settling out. The liq. is aerate to promote aerobic decompsn. and formation of nitrate cpds. The liq. is circulated for a distance until the liq. is substantially devoid of oxygen when it reaches again the point of raw sewage injection. The liq. containing nitrates and the raw sewage are circulated together for a second distance in which denitrification proceeds until it reaches the next point of aeration. Liq. is continuously removed for clarification at about the same rate as the rate of injection of raw sewage. A portion of the settled sludge is returned to the reservoir. The average retention time in the reservoir is 24 hrs. The second distance is at least 10% of the sum of the first and second distances. For treating sewage so that its organic contents are broken down and the nitrates so formed are further broken down into their basic elements.
