Title: Leg and foot support for chiropodists chairs - has telescopically extending holder with separate supports ensuring constant knee support
Inventor: FISCHER RICHARD
IPC: A47C1/06
Filed: 1974-02-07
Abstract: The chiropodist's chair is designed to support all parts of the legs and feet in whatever position is required and for this purpose the chair has two leg/foot supports which are each pivotally mounted on a telescopically extending holder. The foot support is connected to the holder by a bracket which is connected in articulated fashion to the holder on one side and the foot support on the other whilst the leg support is connected in articulated manner to the upper part of the holder by a bolt whereupon it can be raised up by a spring. This allows the knee to be supported when moving the leg support whilst the foot remains unmoved on the foot support. The leg support is connected to the holder at a point remote from the edge of the chair.

Title: Pressure impulse series production system - connects servo-motor alternately to hydraulic pressure and return pipes
Inventor: SIEKE INGRID
IPC: F15B21/12
Filed: 1974-04-19
Abstract: Linear or rotary vibrations are produced by hydraulic forces in servo-motors, by feeding to the hydraulic servo-motors a series of hydraulic pressure in pulses. This is done by connecting rapidly and alternately a pipe leading to the servo-motor to the hydraulic pressure and return pipes. Where th servo-motor is double-acting, the pressure impulses can be applied to the opposite sides of the motor in antiphase. At each changeover, a quantity of oil under pressure can be fed to the servo-motor slightly large than that discharged to the return pipe. The actual pressure can be varied during an impulse, so that the amplitude of the vibrations can be controlled.

Title: Electrical heart stimulation impulse generator - has freely operating multivibrator with voltage doubler and frequency filter amplifier
Inventor: KOLENIK STEVE ANDREW
IPC: A61N1/365
Filed: 1974-04-19
Abstract: The generator has a freely operating multivibrator producing electrical impulses at a rate desired for heart stimulation in the absence of natural heart impulses, and a voltage doubler output stage with high impedance. To this the impulse generated is applied to produce corresponding output current impulses for application to the heart for stimulation. A frequency filter amplifier amplifies the natural heart impulses within a selected frequency range. A voltage is generated in response to each amplified heart implse in order to nullify the pulse generated byhe freely operating (i.e. without control voltage) multivibrator.

Title: Amplification of signals in non-linear systems - has wave conductors and intermediate storage units with filter elements
Inventor: WOLTER HANS PROF DR
IPC: H03K5/01
Filed: 1974-08-16
Abstract: The procedure for the interruption and/or amplification of impulses in non-linear systems includes a filter system and is applicable to mechanical, acoustical or optical devices. A number of wave conductors are built up in a model with small delay sections which filter out some of the non-linear components. Subsequent mixing of signals of different frequencies reconstitutes the non-linear features and produces magnified pulses, some features being reduced by filter units. The magnification system depends on the energy storage of the significant features of the periodicity of the non-linear system.

Title: Movable blade reversible hydrodynamic drive - with axially moving turbine wheels and reversible pump motor
Inventor: HELFER FRIEDRICH DIPL ING
IPC: B60W30/18
Filed: 1975-02-01
Abstract: The reversible hydrodynamic motor has the pump section driven by a reversible electric motor with the pump wheel linked to the motor shaft by a spiral thread. The position of the pump wheel on the thread depends on the direction of rotation of the motor, with the wheel being thrown to either end of the thread. The top part of the wheel is fitted with two sets of blades to provide thrust in two directions. The construction of the hydrodynamic motor is thus kept as simple as possible, with only one moving component, and with one turbine wheel being driven by either set of pump blades, depending on the axial position of the pump wheel.
