Title: Electrolyte particle electronic analysis appts. - uses series circuit with detector amplifier threshold valve unit and amplitude analyser
Inventor: COULTER WALLACE HENRY
IPC: G01N15/12
Filed: 1975-09-08
Abstract: The particle analysis equipment utilises a detector (15) formed from a membrane, a current source, a manometer, input and output contacts and means for liquid transport. The detector output is connected to an amplifier (16) and thereafter to a differentiator (18) which may be built up from a resistor and a capacitor. The differentiator output has a diode by-pass to earth which abbreviates the positive pulses, so that the trailing pulse flank signal proceeds to a threshold value circuit (22) with level controlled by a potentiometer (24). The final stages are an electronic switch (26) and an amplitude analyser (32). A direct connection (34) exists between the detector (15) and the analyser (32) so that the latter is responsive both to particle amplitude and its differential coefficient.

Inventor: HAMMER WALTER
IPC: G04G99/00
Filed: 1975-09-15
Abstract: A frequency generator comprises a quartz crystal controlled oscillator subjected to at least one variable physical parameter such as temperature and has an arrangement for calibrating the frequency with respect to a standard signal with simultaneous compensation for variations of the physical parameter(s). This arrangement comprises a first set of selectable memories storing values to control the division ratio in a dividing chain.

Title: Cooling system for stirrer motor - consisting of box type housing around motor to give chimney effect
Inventor: GEPPERT HORST WOLFGANG
IPC: H02K11/28
Filed: 1975-10-18
Abstract: Stirring and mixing device has electric motor with a coupling joining the stirrer shaft to the motor. This motor is surrounded by a tubular housing so as to form a vertical duct around it. The housing is carried by the same support as the motor e.g. by a mounting plate. The power inlet to the housing is in about the same plane as the coupling on the shaft. The agitator assembly is then formed from a shaft with an impeller on the end joined to the motor shaft via a coupling. The housing contains a number of slots to allow passage of air. Used with chemical reactions where increases in viscosity ion occur during the course of the reaction. As the viscosity increases, the loading of the motor also increases tougher with the heat generated. If the motor overheats, its insulation melts and it burns out. This could be a fire hazard. Simple overloads could cause problems in the plant operation. The cooling system described avoids this.
