Patent FR-2208693-A1 (FR)
IPC: A63C9/085
Filed: 1972-12-01
Abstract: A front toe stop for mounting on a ski, comprising a body for fixing to the ski and upon which a jaw is pivotally mounted. The jaw grips the front toe part of a ski boot sole. The jaw is normally pressed against two lateral abutments by a spring-loaded rod in the body which permits the jaw to pivot about either abutment under the effect of lateral forces exerted on it in opposition to the spring. The spring tends to restore the jaw to its normal position while allowing the sole of the ski boot to escape when the lateral forces exceed a certain limit. The rod is pivotally connected to the jaw by a partially screw-threaded pin which is perpendicular to the ski. By rotating the pin, the height of the jaw relative to the rod, and thus to the ski, can be adjusted to suit the thickness of a particular ski boot sole. Provision is made for preventing undesired alteration of the height of the jaw relative to the ski once the height is set. This is accomplished by members of plastics, for example, which engage the thread of the pin and prevent by friction undesired rotation of the pin. Alternatively, the screw-threaded portion of the pin passes through threaded co-axial holes in a yoke at the end of the jaw or the rod, the arms of the yoke being elastically deformed by the pin so as to apply a frictional load to the thread of the pin.

Title: Intrusion radar ignores swinging targets - responds only to targets which approach steadily even if hesitant
IPC: G01S13/56
Filed: 1972-12-13
Abstract: Intruder detection radar uses the doppler effect to detect moving targets, but as it ignores oscillating targets. The target echoes are split into two quadrature components each of which is resolved into phase detected signals. By sampling one channel whenever the othe ris zero and determining by logic circuitry whether phase shifts are continually bulding up or oscillating over many wavelength equivalent, a swinging target can be ignored while an intruder approaching on a random path will be correctly identified.

Title: Pendulum head for submerged-arc welding - using a pulse generator to control electrode swing in welding gap
IPC: B23K9/30
Filed: 1973-09-19
Abstract: A pulse-generator with adjustable frequency is used to control the side to side swing of the welding-head in the welding-head in the welding-gap, and the movement corresponds to a predetermined fraction of the interval between two pulses, the remaining fraction constituting a period of rest. The pendulum is moved by a double-acting compressed-air cylinder, its normal movement being controlled by a guide-roller located at the bottom of the electrode-wire feeder; this guide-roller swings between the two sides of the gap between the two plates being welded. A pulse-generator and a series of valves control the supply of air to the cylinder and hence the movement of the pendulum w.r.t. time. During the interval between the pulses, the pendulum remains at one side of the welding gap.

Title: Jet engine reheat pipe protection device - has sleeve with flange gripped between segments allowing radial expansion
IPC: F02K1/82
Filed: 1973-12-03
Abstract: Sheet metal sleeves inside the pipe form an annular protection space for an engine with after-burners. The upstream end of the sleeve has a crown-shaped flange. Angle section segments each have one flange secured to the pipe and extending upstream, while their other flanges shut off the annular space between sleeve and wall of pipe completely. These other flanges bear alternately against opposite sides of the sleeve flange so as to grip it between them while allowing it to slide. An annular support mounted on the wall of the pipe secures the downstream end of the sleeve while allowing sliding motion. Sliding of the sleeve flange allows for radial expansion of the sleeve, while the downstream support allows this in the axial direction.

Patent FR-2265162-A1 (FR)
Title: Remote control system for lorry mounted crane - uses potentiometer and position comparison signals
IPC: H01F7/18
Filed: 1974-03-21
Abstract: When this system operates a hydraulic reversible piston, fluid is pumped into either end of the piston cylinder. This is controlled by a valve unit whose ports are opened and shut by an axially moving valve carrier. Its movement originates from solenoids at either end of its shaft. As it moves, it deflects a potentiometer and creates a voltage varying between +V and -V. This is compared to a control potentiometer output by an electronic comparator and any resulting difference output is used to drive one or other of the solenoids, thus moving the valve carrier until a null is obtained. In this way a piston can be remotely controlled.
