Patent FR-2322220-A1 (FR)
IPC: B23H9/16
Filed: 1976-08-30
Abstract: A device and process of electrolytic precision drilling of a plurality of in-line boreholes formed in a row, the boreholes having skewed axes and serving as cooling air holes in a workpiece includes a plurality of tubular electrodes for passing a stream of electrolyte therethrough, the stream being directed at the workpiece, an electrolyte manifold head, the tubular electrodes being attached thereto, guidance means which have an upper edge and are provided with coaxial guidance bores for each of the bores to be formed in the workpiece for receiving the tubular electrodes respectively, and where the guidance means are rigid with the workpiece, and feed means for the tubular electrodes. The electrodes are dimensioned for a guidance-free length to remain between the attachment point of the tubular electrodes of the electrolyte manifold when the electrodes reach a final bore depth in the workpiece; that length is at least equal to fifty times the diameter of one of the tubular electrodes. The manifold head includes holding means for the tubular electrodes and the holding means includes an elastic material which has a modulus of elasticity not exceeding 500 kp/mm2; the electrolyte manifold head has a direction of feed which coincides with a line bisecting the axes of the outermost boreholes of the row.

Title: Rolling combed fibres into sliver - after laterally displacing and overlapping portions of circularly combed fibres
Inventor: SLYVAKOV VLADIMIR EGOROVICH
IPC: D01G19/00
Filed: 1976-09-08
Abstract: A combed sliver is formed by successively combing leading and trailing ends of fibre lap portions using a circular comb, placing the combed portions (B) onto each other whilst laterally displacing the portions parallel to the comb axis, and rolling up the combed web about an axis at an angle to the direction of displacement of the combed portions so as to form a sliver. The structural non-uniformity in the combed web due to the overlapping of the separately combed portions is eliminated by rolling the overlapped portions into a sliver. The fibres can be continuously fed to and withdrawn from the comber. The number of subsequent drawing stages is reduced.

Title: Altitude sensor providing audible warning to parachutist - has hand driven by barometer capsule with reflective surface moving to couple LED and phototransistor
IPC: B64D17/56
Filed: 1976-11-02
Abstract: A barometric capsule provides a signal as a parachutist passes through a predetermined altitude at which parachute should be opened. A vibrator is activated to produce audible sound. A hand in a barometric capsule has a point (25) which passes over a photocoupler (30) when the required altitude is reached. Radiation from a luminescent diode (30a) is reflected from the pointer to a phototransistor (30b) whose emitter current triggers a thyristor (32). The thyristor provides a return path for battery (40, 41) current through a sound vibrator (5). A connector (51) permits disconnection of battery current and a press button (35) allows the warning to be switched off during landing.

Title: Board game with astrological theme - has counters with zodiacal signs moved over squares depending on affinity with opposing counters
IPC: A63F3/02
Filed: 1977-01-17
Abstract: The board game has an astrological theme and is played on a squared surface. Around the four edges of the board are two sets of twelve zodiacal signs, each set coloured differently. The two players each have a different coloured set of twelve counters these being also marked with the zodiacal signs. Each player positions his counters in the marked squares along the edges of the board. They must be moved over the board to enter the opponent's positions. Their movements depend on the astrological affinities between the signs, as marked on the counters, and they can also be taken.

Title: Surface aerator for biological purificn. of waste water - has channels flowing around horizontal rotor for more efficient contacting
Inventor: HAMEL RAYMOND
IPC: B01F3/04
Filed: 1977-08-02
Abstract: Aerator uses a partly-immersed rotor turning on a horizontal axis, within a flow guide channel. The flow channel has a horizontal base below the rotor. The size of the base is such that its perimeter encloses the vertical projection of the plan view of the rotor. The dia. of the rotor is pref. 60-80 cm., the depth of immersion of the rotor is 10-30 cm. and the channel base is clear of the rotor blades by 5-10 cm. The channel pref. directs and evenly distributes incoming water to the rotor. The channel discharge outlet pref. reintroduces aerated water downwards at an angle of 20-30 degres to the horizontal. Aeration is achieved more efficiently with reduced energy requirement. This is mainly due to more intensive contacting, higher pumping speed and controlled direction of discharge.
