Title: Transistorised high tension ignition system - has capacitor charging resistor which is formed when emitter collector circuit is active
Inventor: RUF WALTER
IPC: F02P3/055
Filed: 1974-10-18
Abstract: The circuit has an alternating current generator in place of mechanical contact breaker points and a threshold value switch as in 2244781. It is further improved to give a more precise dwell in the primary winding at all engine speeds. The current flow through the primary winding is able to restart before the signal generator has reversed the threshold switch and the capacitor is again charged by the transistor emitter collector resistance circuit. Since the tension at the capacitor increases linearly, the primary flow output time is decreased correspondingly to give the best current flow times at a relatively large speed range.

Title: Dial illumination for alarm clocks - is actuated by tilting clock with mercury switch to complete lamp circuit
Inventor: WISSER OTTO
IPC: G04B19/30

Title: Inner cooling of extruded hollow profiles - by introducing flowing coolant at adjustable pressure-residence time into profile
Inventor: HESSENBRUCH ROLF DIPL ING
IPC: B29C48/90
Filed: 1975-02-15
Abstract: Inner cooling of extruded hollow profiles, esp. pipes or hoses of thermoplastic material is effected by (a) cooling/calibrating the outer surface of the extruded hollow profile after it leaves the extruder, and (b) introducing a flowing coolant, esp. water, under an adjustable superpressure inside a limited cooling section so that it wets the inner face of the profile, during the calibration of the outer surface, the average residence time of the coolant in the cooling section being adjustable. In order to increase the flow velocity the static pressure of the coolant at the end of the cooling section is lowered, and the coolant is sucked out of the inner cooling section. Very efficient inner cooling of the hollow profile. Cooling is very uniform as a result of the control of the pressure/residence time of the coolant, and prevention of dead spaces in the cooling section. The appts. is relatively simple and easily controlled.

IPC: F15B11/08
Filed: 1975-02-26
Abstract: The hydraulic system is for supplying the operating hydraulic equipment of an agricultural tractor, with a hydraulic source, which feeds the required feed flow only when the leads are connected in.

Title: Tig welding current source - controls thyristor firing by current transformer feedback in primary circuit for half wave symmetry
Inventor: JUNG WERNER
IPC: B23K9/073
Filed: 1975-03-18
Abstract: In the parent patent (DT 2504870) a current supply for a TIG welding machine with two antiparallel thyristors in the primary circuit of a welding transformer is controlled by the signals from a current transformer in the secondary (welding) circuit to maintain symmetrical half-waves of the welding current in both directions. In this addition a current transformer, pref. with a centre tap, is arranged in the primary circuit of the welding transformer to control the two thyristors in a differential amplifier circuit. This makes the thyristor firing circuit more independent of any disturbances arising from the welding operation. The phase-controlled thyristors keep the current strength in the two half waves strictly symmetrical.

Title: Cardiac stimulator monitoring appts. - has comparator for stimulation signal and reference frequency from quartz oscillator to actuate alarm
Inventor: STEMPLE GUENTER
IPC: A61N1/08

Title: Flame photometer burner - has pressurised precombustion chamber which maintains constant flame height
Inventor: SITEK GEORGE J
IPC: G01N21/72
Filed: 1976-03-23
Abstract: The protable flame photometer has a pressurised precombustion chamber to maintain a constant flame height under varying environmental conditions. The burner (10) has an air inlet (11) a sample gas inlet (12) and a fuel inlet (13). The flame is formed in a combustion chamber (14) enclosed by a cylindrical wall (26) around the burner. The flame is observed through an optical fibre light guide (15) extending through an outer wall (21b) and located opposite an aperture (15') in the combustion chamber wall. The fibre leads to a detector (41) which can carry out any desired analytical operation, such as the determination of manganese in a steel sample. A chimney takes away fumes from the flame and produces an updraught wall to protect operators from accidental contact. The housing is divided into two by a baseplate (43) with a number of apertures communicating with a lower chamber (22). A fan feeds air through the annular space (20) of the chimney the lower chamber (22) and the space (23) around the combustion chamber.
