Patent FR-2244625-A1 (FR)
Title: Oscillating sheet gripper drive - has hydraulic control unit linked to oscillating gripper shaft for rotary printingmmachine
IPC: B65H5/10
Filed: 1974-09-19
Abstract: The control circuit has a setting indicator which interacts with a cam disc, an actual-value indicator operated by the piston rod whereby the two indicators are connected to an actual-desired-value differentiator in the form of a variable gain amplifier. The difference recorded is used to control a servo-valve for the printing ink supplied to the piston. The two indicators are constructed as potentiometers. The servo-valve is a four-three way valve. The actual-desired-value difference is adapted to different machine speeds by means of a centrifugal governor. The design is intended to reduce oscillations and eliminate double impressions during printing.

Title: Cross country vehicle with independent wheels - has pairs of in-line wheels on pivotal triangular frames
Inventor: BERG CHRISTIAN VAN DEN
IPC: B60G9/02
Filed: 1974-09-20
Abstract: A suspension system for a cross country vehicle with independent wheels driven by respective motors coaxial with the wheels has successive wheels, one behind the other in pairs, carried by a vertical triangular frame, the centres of rotation (4, 5) of the wheels being located at the two lower corners, and the frame pivoting about an axis (3) at the upper corner so that the frame can tilt within its own plane. This frame supports the wheels between its side, like the forks of a cycle, and can also tilt about an axis parallel to the axis of the vehicle. These frames are attached to longitudinals which can swing up as the triangles tilt in their planes.
Patent FR-2250217-A1 (FR)
Title: Line blown through cable duct by air pressure - using multistage foam rubber piston attached to lead line
IPC: H02G1/08
Filed: 1974-11-06
Abstract: The arrangement utilises a high volume low pressure air supply and is esp. useful where the cable duct bore is not smooth, or where there are already some cables installed. The pistons are in the form of foam rubber stoppers linked together by a line to which the lead line is attached. The stoppers, being flexible, can roughly conform to the duct profile, and also form around an existing cable. The multiplicity of stages ensures sufficient working area for the air pressure and increases the leakage path resistance. The process can also be adapted to clean the cable duct bore before the cable is pulled through. For this purpose a brush is fixed to the lead line in the forward direction and a rubber ball substituted for the return.

Title: Automatic telephone dialling code system - has subscriber numbers sequentially recorded on magnetic layer and retrieved by storage code
IPC: H04M1/276
Filed: 1974-12-31
Abstract: The telephone automatic dialling system records coded subscriber numbers on a magnetic layer (14) rotated by a motor, clutch, gear train (13, 15, 16) and intermittent cam (17). The number is recorded by use of a 0-9 keyboard (11) which selects a combination of 2 from 7 frequencies (20). The first number of the dialling code is recorded in a space on the magnetic layer in sequence with all the first numbers of all the stored dialling codes. The second number is similarly recorded in sequence with all the other second numbers. A recorded number is retrieved by selecting its storage code number (12). It is then converted to either an AC or DC dialling signal. This system of sequential recording allows an easier recall of numbers.

Title: Automatic tuning cct. - designed for capacity diode tuned receivers and effective for AM and FM stations
IPC: H03J7/28
Filed: 1975-03-03
Abstract: The tuning circuit is fully electronic and automatic, is proof against interference and is sensitive to even very weak stations close to strong one. The tuning function remains unaffected by impulses arising from the frequency modulation on the flanks of the intermediate frequency circuits. The oscillating circuit are tuned to the intermediate frequencies of the intermediate frequencies of the amplitude modulated and/or frequency modulated oscillation. Each oscillating circuit has a discriminator and a capacity diode switched in paralle which periodically changes its capacitance value via a pulsed switching stage. A rectifier stage follows the discriminators and has a limited filter connected to it, which in turn has a scanning discriminator coupled to it.

Title: Variable lift valve mechanism in IC engine - reduces lift of inlet valve in accordance with increase in suction pressure
Inventor: CHARIATTE GEORGES
IPC: F01L13/00
Filed: 1976-07-08
Abstract: The inlet valve (12) is operated by a rocker arm (14) against the action of the closing spring (13). The rocker arm is moved by a push rod (20) which is lifted by a cam (16).

Title: Sealed plunger for flowmeter calibration loop - has bearing exchanger and uses adjustable bush and seals for two position sealing(NL130177)
IPC: G01F25/00
Filed: 1976-07-09
Abstract: A hydraulic switch used in a flowmeter test and calibration instrument is designed for improved sealing in both switch positions. The switch forms part of an interchange section (24) of a pipe loop (10) through which the time of travel of ball bearings is measured between detectors (17, 18) separated by a known distance.
