Title: Injection moulding machine for foamed thermoplastics - with two stage transfer to prevent premature expansion
Inventor: ALWES DIETER
IPC: B29C45/72
Filed: 1973-06-02
Abstract: Injection moulding machine for material contg. at latent blowing agent, where the melt is preplasticised by a screw extruder operating at sub blowing temp. The melt is then passed through a transfer chamber having a mandrel turning in a narrow clearance (3 mm) passage leading via a conical outlet to a high pressure accumulator chamber. A ram discharges controlled volume shots from the accumulator to the mould cavity. The transfer chamber is hot enough to activate the blowing system, but the pressure there and in the accumulator are too high to tolerate expansion prior to the material entering the actual moulding cavity. The clearance in the transfer chamber may be 1 mm, with striations to induce forward flow. The mandrel may move axially to maintain a set backpressure. The tip of the rotor may have annular broken flights for subsidiary homogenisation. Suitable for rapid and closely controlled heat transfer to promote the blowing initiation reaction.

Title: Electronic exposure meter for camera - has operational amplifier to generate and store control signal
Inventor: WAGENSONNER EDUARD
IPC: G03B7/083
Filed: 1973-10-23
Abstract: A photo resistance forms one branch of a voltage divider circuit which provides one input into an operation amplifier, with a second input formed by a fixed and variable resistance. A thyristor, field effect transistor of Darlington pair form the other half of the voltage divider with the photo resistance. When the exposure measuring circuit is separated from the rest of the system the op-amp generates a control signal which is stored for a set minimum time in a capacitor, and with the signal maintained by the circuit for that set time. This allows the exposure setting system ample time to set the controls after the mirror has been swung aside in SLR cameras. The system operates with no moving parts. The gain of the op-amp and the settings of the other voltage divider circuit, are adjusted so that the impedance of the photo sensitive system is the sae as that of the servo circuit.

Title: Protection circuit for thyristors - can detect voltage climbing rate so that high voltage spikes cannot damage thyristor
Inventor: THIELE GERD DIPL ING
IPC: H03K17/082
Filed: 1974-09-19
Abstract: The circuit protects against overvoltage between the anode and cathode when the thyristor is in the non-conducting state. In thyristor timing circuits, when the thyristor typically is fired from some magnetic pick-off device, overvoltage across the thyristor can occur as a result of insulation failure, or pickup and this can be sufficient to destroy the thyristor. The protection circuits detect the overvoltage condition and fire the thyristor. In the basic circuit, a voltage detection chain consisting of a zener diode (5), a unijunction transistor (6) and two capacitances, is attached to the base of the thyristor - or to the bases of two parallel thyristors where appropriate - and this fires the thyristor when overvoltage occurs.
