Title: Multiple chamber tube containing ingredients to be mixed - has adjustable slider section superimposed on tube end and passage slot for equal mixing
Inventor: FISCHER ARTUR
IPC: B65D35/22
Filed: 1975-11-13
Abstract: Multi-chamber tube has separating walls extending in the tube's longitudinal direction to form chambers for the components of a multicomponent substance reacting, when the components are mixed, e.g. a twin component adhesive, foamable plastic. A slider section, adjustable along the length of the tube, is superimposed onto the tube end which has a passage slot corresponding to the thickness of the empty flat tube. The passage slot of the slider section is shaped to be wider towards the tube opening. The outer surface of the slider section is roughened to facilitate adjustment.

Title: Labeller with support band for self stick labels - uses machine drive to part label from band with transporter roller and parting edge
Inventor: SUMP LOTHAR ING GRAD
IPC: B65C9/18
Filed: 1976-01-05
Abstract: The labeller has self-adhesive labels on a support band. There is a band stock and positive roller with a dispenser edge to part the label from the band. A drive forming part of the machine separates only part of the label from the band (7,8) and then drives it out beyond the machine for removal, leaving the remainder of the label still on the band. The label is pulled off from outside the machine and parts of the machine continue to move until the label is free of the support band (8). The transport roller (3) is fitted with a freewheel coupling (15) and is responsible for positive entrainment of the band labels entering the machine (2) and the emerging support band (8) for these. The push or pull used to apply the label to the object should be used to pull the remainder of the label off the band (8).

Title: Distortion compensating circuit for nonlinear circuits - has square wave input shaped and used to control analogue relay generating output
Inventor: CHAMPAGNE RONALD E
IPC: H03J7/18
Filed: 1976-04-02
Abstract: The distortion compensating circuit, particularly useful with voltage controlled diode tuning units, is based upon semi-conductor devices in an integrated form insensitive to temperature and humidity variations. The compensating circuit accepts a digital input in the form of a square wave from the digital control circuit of the timing system. The signal is of constant frequency with variable mark/space ratio dependent upon the stored data in the tuning system. The signal is processed through an analogue relay (12) generating a constant amplitude output with a pulse width equal to the input. An RC filter with a long time constant provides a compensating signal, over an amplifier, for the other analogue switch (18).

Title: Concrete reinforcing rod spacer with protruding wire loops - has deformable slit in form unit for loop ends insertion
Inventor: KATHEDER HANS ING GRAD
IPC: E04C5/20
Filed: 1977-04-04
Abstract: Fixture for reinforcing rods for concrete, using spacers made up from a form unit and two wire loop ends protruding on one side of this and anchored in it. There is a slit in the side (12) from which the wire loop shackle ends (17, 18) protrude, for insertion of these ends, which are made of resilient material. The slit is then deformed so that the loop ends are irretrievably connected to the form unit, so as to be elastically deflectable. When deformed, the slit can be virtually closed at the centre, and open where the wire loop ends emerge from the form unit. The slit shape is readily adaptable to the necessary wire loop shape and size, providing loose retention or firm anchorage of the loops as required.

Title: Optical particle suspension analyser - detects dispersion and polarisation of electromagnetic radiation directed through suspension
Inventor: GLOCKMANN WALTER
IPC: G01N21/21
Filed: 1977-07-29
Abstract: The analyser uses photodetectors to detect electromagnetic radiation dispersed by the particle suspension and provides a value proportional to the amount of polarisation, which is dependent on the mean diameter of the particles held in suspension. This value is combined with a further value indicating the amount of radiation dispersed and/or absorbed by the particle suspension, to provide an output signal. Pref. the quotient of the latter two values is obtained to provide an output signal which is a linear function of the specific number multiplied by the mean dia. of the particles in the suspension.

Title: Digital multiplexer for flight simulators - provides amplified synchronising signals via strobed A=D converters
Inventor: TUERK HANS
IPC: G06F17/50
Filed: 1977-08-31
Abstract: The multiplexer comprises a central processor (11) which calculates the flight condition from cockpit inputs and passes the values to be indicated to an intermediate computer (12). These signals, corresponding to the angular parameters for the instruments (A1, An) are stored. The microcomputer calculates the amplitude values for control signals and these are parallel-fed to parallel-connected A/D converters (13.1-n2). Strobe pulses from a programmable communication interface (12.3) address each A/D converter in turn so that all amplitude values for the synchro channels are fed to the converters from 1 to the highest address in succession. The amplitude values are modulated with a reference signal and amplified (13.1.1-n.1.2) so that they appear as an output signal with the correct sign.

Title: Target approach aiming system for pilotless aircraft - generates scaled images and compares with actual scene for compensation for final approach
Inventor: HESSE KLAUS DR RER NAT
IPC: F41G7/34
Filed: 1978-07-20
Abstract: The target approach control system is used for automatically steering a missiel. The target image is processed by an electronic system generating steering signals by cross correlation between the actual scene and the stored images. The steadily increasing size of the target area or image does not cause loss of accuracy on final approach. During the approach flight each sensed image is correlated simultaneously with two stored target images, respecting the target area on smaller and larger scales than the actual image. The total deviation is computed by weighting of the deviation signals of each correlation result with a function of the associated correlation max. values.
