Patent FR-2274400-A1 (FR)
Title: Rotating grinder on mobile arm - sensor monitors grinder wear, increases speed, adjusts arm travel with wear
IPC: B24B27/06
Filed: 1974-06-14
Abstract: Motorised cutting machine with rotating grinder (5) on moble arm (2), automatically compensates for grinder wear during repetitive cutting or sectioning operations. Its peripheral grinding velocity and the grinder support arm travel are continuously monitored and adjusted for optimum grinder use. A sensor (26) e.g. pneumatic, can monitor grinder wear, coming into contact with the grinder when at rest. The machine control system causes sensor displacement either in a direction parallel to the grinder support arm displacement, or in a direction passing through the axis of rotation of the grinder. Detection can be via a contact actuated by falling workpiece cut-offs. The grinder is powered by a hydraulic motor mounted on a support arm.

Title: Compressed air operated engine - has series of cylindrical vessels connected by hollow shaft with reaction nozzles
IPC: F03G7/10
Filed: 1974-07-23
Abstract: The engine consists of a number of cylindrical vessels mounted on a common hollow shaft. A gas with energy (W) at pressure (P) and volume (V) is supplied to the shaft and flows into a transverse pipe with jets fitted inside the first vessel. The jets provide a reaction causing the vessel to rotate and the gas then flows into the next vessel at a reduced pressure (P2) where the process is repeated until the gas finally emerges from a valve with the energy (W) as at the beginning. A compressor is used to recompress the air exhaust from the last cylindrical vessel before recycling.

Title: Permanent treatments of textile fabrics - using organic solns. of polyols and polyisocyanates on moist fabric
Inventor: CREUTZBURG PETER
IPC: D06M13/395
Filed: 1976-05-21
Abstract: Modifcn. of textile fabrics by treatment with a solvent (A) contg. a mixt. or reaction product of a high-molecular polyol (B) and a stoichiometric excess of a polyisocyanate (C), so that phase boundaries are formed in the fibres, allowing a linking of the reactive additives to the fibres and a permanent bonding between the fibres. Esp. used for treatment of non-woven fabrics made by needling methods, wholly or partly from cellulose, esp. viscose fibres, to improve resistance to shrinking, pilling, washing, creasing etc. Use of organic solns. instead of aq. dispersions eliminates the need for capping NCO end-groups, and prevents complete penetration of the fibres with adverse effect on the feel.
Patent FR-2316688-A1 (FR)
IPC: G11B15/58
Filed: 1976-06-25
Abstract: The magnetic tape apparatus for data processing systems comprises a vacuum buffer chamber (Pu) which is subdivided into three regions lying one above the other. The upper region and the lower region serve for controlling the drive of the winding motor (Wm) in one direction or the other and the middle region serves for controlling the braking of this motor. When the apparatus is running, in order to avoid a multiplicity of unnecessary back-and-forth motions of the tape when the tape loop is positioned in the middle region of the buffer chamber (Pu), which result in an unnecessarily frequent and unnecessarily long excitation of the motor windings and, associated therewith, an increase in the motor temperature or the entire surroundings of the motor, a first device (RS) detects not only the direction of rotation but also the speed of rotation of the tape roll (Bw). A second device (WS) prevents the activation of the winding motor when the tape loop is in the middle zone in order to drive or brake whenever the speed of the roll (BW) drops below a certain value.

Title: Control method for physical characteristics of fluid medium - is by transmission of ultrasonic vibrations through pipe wall at angle given by specified relationship
IPC: G01N29/34
Filed: 1976-10-12
Abstract: Vibrations are transmitted to the medium under control through a sound conducting medium and through a pipe wall at an angle Alpha acute or obtuse, to the pipe exterior, the angle being determined by the relationship: Alpha = arcsin C ( 2.C). where: Co is the velocity of propagation of ultrasonic vibrations in the sound conducting medium, and C is the velocity of propagation of transverse ultrasonic vibrations in the material of the pipe wall. The frequency f of the ultrasonic vibrations being transmitted is selected according to another specified relationship. Parameters of the ultrasonic vibrations, passed through the medium under control, are then measured and their value is used to determine the value of a parameter being controlled.

Title: Remote control missile firing device - has conductor cable extending between current generator and internal fuse
IPC: F42C11/00
Filed: 1976-10-15
Abstract: The remote-controlled missile firing device allows the launcher to detonate the missile before or after impact. The missile is connected to the launcher by a conductor cable, running between a current generator and a fuse inside the missile. A switch closing the detonation circuit can be provided on the rear end of the cable. For short-range work, a winding mechanism can be incorporated in the missile itself, while for longer ranges this mechanism is incorporated in the launching device, or is independent. The design affords a convenient system of putting down a screen of teargas grenades, only detonated if demonstrators attempt to cross it.

Title: Large cabin cable railway carrier locking brake - has swivelling brake shoes with elbow lever and pressure rods
IPC: B61H9/02
Filed: 1976-12-10
Abstract: The carrier cable brake is fitted on the running-gear of a large-gondola cable railway, with carrier and traction cable, mounted on its main girder. The brake incorporates two brakeshoes, fixed on the main girder (4) of the running gear, and swivelling about the carrier cable. These are hinge-connected by an elbow lever rod (10), and by a compression rod (11) with a spring damper unit (8). A locking device, responding to traction cable tear, is mounted on the compression rod end. A cable tear unbolts this, so that combined release spring force and elbow lever rod action results in raising of the bracking force or attainment of the characteristic curve. Constant braking force and reliable operation are ensured, even after prolonged braking action and concomitant wear.
