Title: Brake to hold ski at rest when unworn - has spring loaded pivoting anchor arms held reracted by ski boot
IPC: A63C7/10
Filed: 1973-05-11
Abstract: The automatic brake holds a ski at rest when not being worn. In use, the brake is held clear by the ski boot. Each ski has two brake tines fixed to a rod (4) pivoting in brackets forming part of a cover (3) over the mechanism. A stirrup has two spring loaded arms and these keep the brake out of action as long as the pressure of a ski boot is against the stirrup. Then the boot is removed, a spring bias (7, 10) plus the weight of the tines push the latter into the snow.

Title: Helical vibrator elevator and conveyor - has separate horiz. and vert. vibration control at base and centre
IPC: B65G27/16
Filed: 1973-06-15
Abstract: The elevator consists of a helical trough wound round the outside of a central cylinder. The assembly is carried on vertical helical springs, which absorb the vibration movement of the elevators. A vibrator motor is fixed to the underside of the assembly and generates vertical vibrations. A second vibrator motor is fitted to the central part of the assembly and this generates horizontal vibrations. The motors may be controlled separately. A variation suspends the cylinder from the centre and allows the horizontal vibrations of the upper and lower halves to be in opposite directions, thus operating with helixes of opposite hand.

Title: Microfilm analyser using fixed source as analysis beam - has screen forming secondary source and step displacement system
Inventor: BEDUCHAUD MICHEL
IPC: G02B26/10
Filed: 1974-08-09
Abstract: A first optical system deviates the analysis beam along a line of known length. The point of impact of the analysis beam on a screen constitutes a secondary source which can move along this line. A second optical system assures the transposition and reduction of the line scanned by the secondary source onto a line of the microfilm. A step-by-step displacement system moves the first optical system perpendicular to the line scanned by the secondary source and a photoelectric detector converts the light transmitted by the microfilm into electrical signals.

Title: Method of measuring displacement or deformation of substances - uses mobile TV camera linked to memory and image recorder and computer
Inventor: CORNEC MICHEL
IPC: G01B11/02
Filed: 1974-12-24
Abstract: The instrument is used for measuring the displacement of viscous masses or the deformation of a material, in which a unit volume of the mass or material is made visible w.r.t. its environmental medium. Thus it is possible to follow its evolution in time and by comparing the image of the phenomenon at a determined instant with the initial image, a measure of the displacement or deformation is possible. The instrument comprises a mobile TV camera, a memory, a device for visualisation of the recorded images, a connection device which transmits the visualised images to a computer and a command device which ensures, by means of the computer, that the measurement and results collection process continues.

Title: Wire electrode feeder testing - particularly for continuous weld wire
Inventor: SAMOKOVLISKY D A
IPC: G01M99/00
Filed: 1975-01-22
Abstract: Wire electrode feed devices are tested by (a) unwinding the electrode wire from the rotating bobbin during the test as a result of the tractive force exerted by the feed device, which together with the bobbin is in a state of relative mobility w.r.t. both to the wire and the bobbin, so that during unwinding, the electrode wire and the feed device are subject to mechanical braking resistance balanced and measured by means of a force-measuring element acting equally on the relatively mobile feed device and on the wire resp. in the feed direction or vice versa, and (b) balancing the two forces to represents the force which the wire feed device can overcome as a consequence of the frictional force between the feed rolls and the wire electrode, permitting the test to be carried out with the simultaneous measurement of the thrust, the feed speed and irregularities in it. Tests of wire feed devices including those of planetary type can thus be carried out with a continuous wire electrode over a wide range of speeds, without risk of twisting or kinking of the wire and permitting determination of reliability and length of life.

Title: Measuring traces of mercury in natural gas - by adsorption, followed by desorption and comparison with standard by spectrophotometer
Inventor: RATARD DANIEL CLAUDE
IPC: G01N33/00
Filed: 1976-07-19
Abstract: An appts. for measuring traces of mercury contd. in a gas, e.g. natural gas, incorporates a circulation system in which there are two traps, contg. gold wool, in series. The first trap acts as a sampling trap, the second as a measuring trap. Both traps can be cooled so that they retain traces of mercury contd. in the gas under test and heated so that the mercury can be driven out. An atomic absorption spectrophotometer is placed after the two traps, in series with them, detecting in a measuring cell the traces of mercury contd. in a vector gas after it has passed through the traps. The appts. includes also a means of standardisation, e.g. a permeation tube delivering a fixed quantity of mercury into the first trap. System provides measurement and control simply and automatically of traces of mercury which could cause corrosion of heat exchanger tubes when processing the natural gas.

Title: Shaft thermal transition element for superconducting rotor - has interior ferrule with grooves pressed against exterior ferrule and providing circulation of cooling liq.
Inventor: GILLET ROGER
IPC: H02K55/04
Filed: 1976-10-28
Abstract: The thermal transition element (16) for the shaft of a superconducting rotor has a hot end designed to be fixed to a support rotating at ordinary temp. The element (16) has a cold end fixed to a central part of the rotor. The rotor being fitted with superconducting windings. The transition element ensures the mechanical connection between the rotor and the rotating support. A ferrule joins together both ends of the thermal transition element. A cooling pipe is in contact with the ferrule and permits circulation of a cooling fluid towards the hot end. The ferrule is made up of an exterior ferrule (48) which is clamped against an interior ferrule (44) so that both ferrules are submitted to opposing compression and tension forces. These forces acting in the plane perpendicular to the axis of the ferrules. One of the ferrules has a groove (52) cut in its face which presses against the other ferrule. This groove permits circulation of cooling liquid. The depth of the groove near to the cold end is made sufficiently shallow to prevent circulation in opposite directions in the two parts of the groove.

Title: Coin feed mechanism for slot machine - has coins fed into elongate channel to roll to mobile stop for release by pressing button
IPC: G07F1/04
Filed: 1976-12-01
Abstract: The coin feed mechanism allows a machine to be activated by a user upon the introduction to the mechanism of a pre-selected coin. The coin is inserted through a slot in the upper face of the mechanism. The coin then falls under the action of gravity, into a longitudinal passage defined by a pair of closely adjacent walls. In the passage the coin rolls down a ramp until it engages a mobile stop. When the coin has reached the stop a push button may be actuated which releases the coin from the mechanism and allows it to fall over a lip into a coin box. The pressing of the button also initiates the machine action selected by the user.

Title: Flange connection for container - has plastic cladding with expanded metal inserts to prevent creep flow
IPC: F16L23/12
Filed: 1977-01-19
Abstract: A container which has a corrosion resistant cladding made from plastic foil (3) has a flange joint (2). A gap between the two parallel flange rings (2) is produced by the location of the trapped edges of the plastic foil (3). When the flanges (2) are bolted together, the plastic foil is being clamped. To avoid the displacement of the plastic material due to creep, when it is under compression, metal inserts (4) are placed inside the slotted edges of the plastic foil. The inserts are made from expanded metal sheet or from flat material with perforations. The creep flow of the plastic material is thus to a large extent reduced.
