Patent FR-2482755-A1 (FR)
Inventor: MEICHL FERENC
IPC: G11B5/48
Filed: 1981-03-05
Abstract: In the case of an advancing and positioning mechanism, in particular for moving a magnetic head serving for the recording and reading of a flexible magnetic disc, the moving band (4) rolls on the drum fitted on the shaft of the advancing motor. As a result, a plastic carriage (5), which carries the magnetic head (6), is taken along with it. The plastic carriage (5) slides on a rod (7) and bears against a supporting rod (8). Due to the forces occurring in the sections of the moving band (4), the plastic carriage (5) is prismatically guided if a suitable geometric design is chosen.

Patent FR-2493950-A1 (FR)
Inventor: NIKOLAUS HEINRICH
IPC: F04B49/00
Filed: 1981-05-14
Abstract: The hydrostatic drive system consists of a primary unit formed from one or more hydraulic pumps and of a secondary unit formed from one or more variable-displacement pump motors. Coupled to the variable-displacement pump motors are small hydraulic-pump motors as signal generators (22) for transmitting a signal value, determined by the rotational speed of the variable-displacement pump motors, for the adjusting device (21) of the variable-displacement pump motors which is formed by an actuating cylinder. The connections (30, 31) of the signal generators are connected to the cylinder spaces (37, 38) of the actuating cylinder, the cylinder space of the actuating cylinder not connected to the control-medium source being connected to a throttle device for building up a specific control pressure. As a result of the associated hydraulic bracing of the piston of the actuating cylinder, the accuracy and responsiveness of the rotational-speed control is increased, even at low rotational speeds of the variable-displacement pump motors, and at the same time its efficiency is improved, without additional hydraulic devices, such as a pressure valve, being necessary. The drive system is suitable, for example, for travelling drives and winches, where the energy recovery has an especially favourable effect.

Title: Quality controlled selective cutter for wood planks - includes defect sensors providing signals for processor control of cutting saw position
Inventor: BOUVARD JACQUES
IPC: G01N21/898
Filed: 1981-06-10
Abstract: A detector analogues the surface condition of a plank as it passes on a conveyor to be fed to a buffer store conveyor. The detector output provides coordinate data for defects on the plank and a calculator issues signals to a control module. This sets tappet positions for plank cutting lengths and also positions the saw. The calculator allows for the plank position on the buffer conveyor feeding the cutter. This ensures that the plants are cut to optimum length considering the defects. From the cutter the planks enter a classification and sorting station where inclined conveyors with adjustable barriers guide the planks to storage bins as controlled by a sorting control module.

Title: Automobile route indicator plotting instantaneous position - has sensor detecting turning manoeuvres held in thermostatic chamber supplied via switch
Inventor: TAGAMI KATSUTOSHI
IPC: G01C21/28
Filed: 1981-09-03
Abstract: The indicator plots the actual position on a two dimensional read-out display, marked along both axes in terms of the distance travelled. The indicator uses signals from a distance sensor (3) monitoring the distance travelled and from a gas flow sensor (2) responsive to the azimuthal deflections caused by the vehicle being turned. The position obtained from these signals is sequentially stored to allow a continuous course to be marked across the display. The gas flow sensor (2) is mounted in a thermostatically controlled chamber (1) held at a constant temp., its supply circuit (7) being responsive to the position of the ignition switch (IG,SW). Pref. the thermostatic control is held in operation for a given period after opening the ignition switch (IG,SW) to allow short journey breaks. The indicator is used to allow the driver to verify the correct course.
