Title: Syringe and container assembly for mixing medical injections - is sterile, inexpensive, disposable and easily operated
Inventor: KOEBEL ERICH DIPL CHEM DR
IPC: A61J1/20
Filed: 1975-10-17
Abstract: The assembly is used for mixing by combining a liq. in the syringe with a second material in the container, the nozzle of the syringe being attached to the stopper of the container. The stopper has a passage connecting the syringe chamber with the interior of the container, and the passage is initially blocked inside the container by an interference fit bung and on the syringe side by the syringe nozzle operation of the syringe to discharge liq. automatically expels the bung from the stopper so that liq. mixes with the second material in the container to provide an injection ready to be sucked back into the syringe. The nozzle should not meet the bung. The assembly is used inside the stopper for preparing a medical injection which has to be mixed just before being injected. It is of simple, inexpensive construction and is easily operated at high speed without special training. Sterility is assured and the assembly is disposable after use.

Title: Staple fibre spun yarns - by twisting spun yarns in opposite direction in axially spaced pneumatic nozzles and delaying twisting after stretching
Inventor: GOETZFRIED KONRAD
IPC: D01H1/115
Filed: 1976-01-30
Abstract: In the parent staple fibres are spun in opposite directions to produce a yarn using a pair of pneumatic nozzles which induce opposite vortical components to the staple fibres as they move axially from one nozzle to the other. In the addn. twisting of spun fibres emerging from a stretching device is delayed prior to entry into the first stage pneumatic nozzle. Pref. the delay is brought about by spreading the filaments along the surface of a frusto-cone, whereby the yarn is twisted in the first stage and double twisted in the second stage, the fibres assisting in the consolidation of the twisted yarn. Yarns have a higher tensile strength.

Title: Airflow control for bubbling water massager - uses phase cutting circuit to air volume instead of pressure
Inventor: SCHWAB MARTIN
IPC: A61H33/02
Filed: 1976-05-04
Abstract: The motor driving the air blower for a bubbling water massage appts. is regulated to maintain the blown volume instead of, as previously, the pressure at a pre-set, adjustable level. The fan has an AC motor (M) which is fed through a phase-cutting circuit (PS). The air volume is measured with a temperature-dependent resistor (Rhi) placed in the blower air stream (suction side) and forming a potential divider with a second resistor (Rh2) which may also be temperature-dependent. A constant current flows through the two resistors, and the potential at their junction is compared with a threshold (given by RV, Ro) representing the desired volume of air: the output of the comparator (OP) regulates the phase-cutting circuit (PS).
Patent DE-2629852-A1 (DE)
Inventor: WEISIGK GUENTHER
IPC: H04Q3/00
Filed: 1976-07-02
Abstract: The arrangement enables the identification and control of subscriber stations which switch over either from the free state to the call state or from the intercept state to the free state, control procedures being instigated for a subscriber station which has been identified as changing its operating state depending on the type of change in operating state which has been identified. The monitoring of the operating state of the subscriber stations requires none of the switching means associated with the subscriber connection circuits (TS) for the independent identification and evaluation of changes in state. In the event of a change in state, a search stimulus is transmitted to a locating device (TE) common to the subscriber connection circuits (TS) which identifies the type of change in state. The search stimuli are generated on the one hand in the event of a changeover of the subscriber connection circuit (TS) from the free state to the call state through closure of the subscriber line loop and on the other hand in the event of disconnection of the subscriber line loop in the intercept state through this disconnection in that a reverse current circuit which runs via the subscriber line loop in the intercept state and via which an initially activated search stimulus is suppressed in the intercept state, is interrupted in the subscriber station concerned. <IMAGE>

Title: Moving symbol carrier on photocomposer - uses optical sensors to detect code markings along edge of perforated symbol strip
Inventor: FEDERAU GREGOR
IPC: B41B27/32
Filed: 1976-10-28
Abstract: A photocomposing machine has accurate controls for moving and adjusting the symbol strip which has edge perforations and e.g. two rows of symbols, one in lower and the other in upper case. The strip has one row of code marks (33) which indicate the thickness of values of a row of symbols and has arranged above it a striplike mark (34) used for adjusting the printed line. A further row of marks (35) extending longitudinally is used to adjust the print symbols in the line direction. Finally a further row of marks (36) indicate the thickness values of the second row of symbols. At least two photoelectric elements are used to scan the marks such that a logic circuit only generates a signal to stop the strip movement when both elements detect the marks.

Title: Electric door-locking system for vehicle - uses motor aperture as flywheel so that lost motion provides motor acceleration
Inventor: GELHARD EGON
IPC: E05B81/24
Filed: 1976-12-18
Abstract: The locking mechanism is driven by an electric motor, the armature of which may be used as an energy-store i.e. a flywheel. Lost motion is built into the mechanism to permit radial acceleration of the motor before the locking action commences. For locking, a pinion acts on a rack pushing a cylinder downwards, closing the gap between the cylinder and a disc. On reaching the disc the cylinder acts through a spring to pull rod downwards, actuating the lock through a lever. For unlocking the cylinder accelerates upwards until it meets the disc which is attached to the rod.

Title: Flame cutting complex profiles in pipes - where inexpensive microprocessor controls burner path
Inventor: HERMSDORF SVEN
IPC: B23K7/00
Filed: 1977-03-28
Abstract: Microprocessor, mounted on a flame cutting machine used to cut pipes or tubes, controls both the rotation of the pipe and the movement of the burner along a path parallel with the axis of the pipe. The microprocessor feeds control signals to the motors moving the burner and rotating the pipe. For producing a complex cut profile in a pipe, the geometric characteristics of the shape required are pref. fed into the microprocessor, which uses mathematical formulae to calculate the control signals fed to the motors. The characteristics are pref. the dias. of two pipes which will be made into a junction; the angle between the axes of the two pipes; and the eccentricity between the pipe axes. Provides automatic control of the burner path w.r.t. a pipe to obtain a complex profile. The geometric characteristics can be read off drawings and fed directly into coding switches on the microprocessor so time is saved.

IPC: G01N1/20
Filed: 1977-06-29
Abstract: In the treatment of liquids which contain radioactive or aggressive substances, hot concentrate solutions develop whose composition has to be continuously monitored by taking samples. A diluted concentrate is to be removed on account of the dangerous handling of these substances. To this end, a bypass line (2) branches off from the concentrate line (1) and returns the concentrate through a valve block (5) to the concentrate line (1). In the process, the valves (11 and 13) connected to a liquid or mixing tank are closed. To take samples, first of all one valve (12) situated in the bypass line and immediately afterwards the other valve (14) situated upstream of this valve (12), as viewed in the concentrate flow direction, are closed. The concentrate quantity thereby retained in the valve chamber (15) is forced into the mixing tank (7) by means of the liquid in the container (3) after the opening of the valves (11, 13), connected to the liquid or mixing tank, as well as of the ventilation valve (9). After homogeneous intermixing of the contents of the mixing tank by means of agitator (18), the samples are taken via the sampling container (8). <IMAGE>
