Patent DE-2017297-B2 (DE)
Title: Frequency synchronising circuit for raster oscillator - compares its output with that of pulse shaper whose gain is controlled by lock-in circuit to increase amplitude only during hunt
IPC: H03L7/10
Filed: 1970-04-10
Abstract: The frequency synchronising circuit, for a raster oscillator, uses a pulse shaper to distort a fundamental frequency and to form a spectrum of harmonics. This is compared with the frequency of the tunable oscillator requiring locking. The output of the tunable oscillator is compared in a phase discriminator with the pulse shaper output. The result is amplified, rectified and low pass filtered and applied to the tunable oscillator's control input via a frequency setting circuit. The gain of the pulse shaper is controlled in time with the frequency sweep by a lock-in circuit responding to the output of the LP filter. The gain is regulated so that the amplitude of the pulses at the pulse shaper output is only increased during the hunt process.

Title: Sharp edged hard cutting particles - made by crushing sintered metal carbide blocks and used to coat steel saw cutting edges
IPC: B28D1/12
Filed: 1970-09-04
Abstract: Particles are made by crushing a sintered hard metal block. The block is first heated to ca. 1100 degrees C and then quenched to ca. -70 degrees C. The material for the block is made by melting and sintering an alloy of 92 wt.% tungsten carbide, 2 wt.% titanium and tantalum carbide; and 6 wt.% cobalt, all in powder form. Particles are bonded to a strip of tool steel by heating one edge of the strip to approx. 600 degrees C; melting hard solder and pouring over the edge while the particles are sprinkled onto the edge.

Title: Toilet flushing unit with pressurised tank - enables the toilet to be flushed using relatively little liquid ejected forcibly
IPC: E03D3/10
Filed: 1971-01-16
Abstract: A cylinder is sealed vertically in the pressurised tank and has its lower threaded end attached to the outlet leading to the toilet. A piston with elastomeric piston rings moves along a valve shaft and has a coiled spring located between it and the top cover to the cylinder. The piston normally rests against a shoulder or stop on the valve shaft. When the operating lever for the toilet is pulled, the release lever at the top of the cylinder is lifted thereby raising the valve shaft so that the valve closure body is itself raised from its seat. The piston then moves back to its rest position whereby the scavenging effect of the water released is increased by its increased out-flow rate. The pressurised tank is contained within a standard vessel.

Title: Blood press. measurement - with indicator between two or more interconnected cuff chambers
IPC: A61B5/022
Filed: 1971-10-22
Abstract: Blood pressure is measured with two or more cuff chambers opposingly connected such that an indicator connected in between, for pressure change or flow, gives a min. of the measured quantity when the vol. changes of the body parts associated with the individual chambers are relatively large according to phase and amt., and compensate each other at the indicator. Preferably, to determine systolic press. the action of the chamber nearer the heart on the indicator is suppressed by bypassing, and the signal for systolic press. is derived from the beginning of the pulsation in the chamber remote from the heart. Blood press. is accurately measured.

Title: Sheet feed mechanism from flat stack - has freely-moving suction head supported by feeler or holder
IPC: B65H1/18
Filed: 1972-05-26
Abstract: The mechanism feed sheets from the top of a flat stack, having an extractor engaging with the leading edge of the topmost sheet and a feeler detecting the height of this edge and controlling a stack lifting mechanism. Above the trailing edge of the topmost sheet is a separating suction head moving up and down and lifting this edge while a feeler keeping the head in a set position is swung clear during the lifting. The head (24) moves freely up and down and is supported by the feeler (25) from the topmost sheet. A holder (52) working in synchronism with the feeler maintains the head at the height determined by the latter while it is swung clear.

Abstract: Pizzas are prepared by mixing a pizza dough, dividing the dough into single portions, forming the single poritions into balls of dough, and placing the individual balls of dough onto individual pizza trays. The dough pieces are pressed to form a desired pizza base and, after proving, the dough is cooked to form a pizza base. The pizza bases are removed from their trays, a sauce is applied, followed by cheese and toppings. The pizzas thus formed are then frozen and packaged. A number of lines, (1,2,3) of de-panned pizza bases are led along a conveyor (4). A series of detectors are used to detect the absence of a pizza base or gap (6) in a line. A base depositing means (10) is used to fill the gap (6) with a pizza base in response to the detection of the absence of a pizza base in the gap. .

IPC: B23K20/00

Abstract: Apparatus and method are described for rapid ball formation at the end of lead wire retained in the capillary wire holding tool of a ball bonding machine. A circuit is coupled between the cover gas shroud and lead wire for establishing controlled electrical discharge between the end of the bonding wire and the shroud, for melting and forming a ball. The circuit includes a DC power supply for delivering a positive polarity to the shroud and negative polarity to the lead wire for drawing a discharge of electrons from the end of the lead wire to the shroud. A capacitor is coupled in series with the DC power supply for receiving the electrical discharge. An impedance is also coupled in series for limiting the electrical discharge current. Charging of the capacitor limits and shapes the electrical arc discharge to a controlled pulse profile of short duration for rapid ball formation. An electronic gate is also used to control pulse duration. The rapid and controlled ball formation avoids necking or thinning of the lead wire which often occurs at the stem above the bonding ball.
