Patent FR-2215395-A1 (FR)
Title: Distributor for overflow from septic tank - for feeding upstream filter bed
IPC: C02F3/04
Filed: 1973-02-23
Abstract: The septic tank used for the bacteriological destruction of faecal matter overflows through the distributor to feed a filter placed downstream. Such tanks are used for houses not connected to a sewer, but the attached filter, often filled with coke, is not used to the best advantage as the liq. is frequently introduced at one point only. The new plant consists of a reservoir of synthetic material, with an intermediate, perforated base for supporting the charge of filtering material. A raised portion of the base coveres an outlet pipe for the filtrate which also serves to allow air to reach the underside of the base. The overflowing liq. from the septic tank enters at the top and ends in a right angle bend fitted with a distributing screen in the form of a pyramid. This has a central depression with grooves radiating in all directions; the screen can deal with the overflow liq. even if it arrives in rushes. The filter assembly can be made at a partic. favourable cost and it is completely reliable.
Patent FR-2223280-A1 (FR)
Title: Pneumatic conveyor for bulk materials - uses induction nozzle to create vacuum and suck powder from silo above
IPC: B65G53/14
Filed: 1973-04-02
Abstract: Material flows from upper container to lower container via an adjustable orifice controlled by relative spacing of the two containers. An inlet duct at this level can be used to promote flow or to add other material to be mixed. The material then passes through control orifices and into a vertical conduit which has air inlet apertures and an external sliding adjusting sleeve. The vertical conduit connects to aligned inlet and outlet passages which carry the compressed driving air. Low pressure to suck material through the system is created by nozzles in the aligned inlet and outlet ducts.

Title: Bottle capsule checking device - measures diameter of capsule in a groove to ensure good fit
IPC: B67B3/26
Filed: 1974-02-12
Abstract: The device measures the groove diameter (25) of the capsule (22). If the measured diameter is greater than a given value, this is an indication that sealing of the capsule is inadequate. The device consists of two rollers (24) whose edges penetrate into the groove (25). The rollers (24) can move laterally such that the measured diameter is less or equal to a critical value. If the diameter is greater than the critical value, the rollers actuate a microswitch (35). The device is hinged about a spindle (39) when used as part of an automatic checking equipment. During this kind of use, a third roller (6) ensures that the two measuring rollers (24) repeatedly engage in the groove.

Patent FR-2241912-A1 (FR)
Title: HV generator regulating loop for electrostatic spray guns - has piezoelectric transducer reducing current as voltage falls enabling earthed object spraying
IPC: H02H7/00
Filed: 1974-06-19
Abstract: The regulating loop has a piezoelectric transducer consisting of ceramics containing lead, titanium and zirconate. The transducer controls the high voltage generator output current so that it continuously decreases as the output voltage falls towards zero. A stabilising oscillator output is fed to the transducer, and its control input receives the rectified output of the transducer so that the oscillator frequency is kept at the transducer resonant frequency. The system enables the insides of long tubes to be sprayed which would normally be difficult because of the screening effect and the resulting discharge occurring when the spray head is close to an earthed object.
Patent FR-2278926-A1 (FR)
Title: Mounting for gas turbine rotor and stator casings - has rotor casing centring pads fitting into elastic belt around stator casing

Title: Rail vehicle table with sliding extension - has press button operating lever to lift extension
IPC: A47B1/05
Filed: 1974-08-02
Abstract: The top is rectangular with a central longitudinal divider, this providing separately operated tables. Each comprises an extension leaf retained under the upper leaf when closed. The lower leaf is pulled out on guides and the upper leaf drops behind it, forming one surface. To close the table, a button is pressed on the front face of the extension and pushes a rod forward against spring pressure. A head on the other end of the rod contacts a rocking lever. The end of this is pushed upwards, lifting the front of the drop leaf and permitting the extension to be pushed underneath.
Patent FR-2284064-A1 (FR)
Title: Metal section for framing panels - has hinged clamping flange formed reduced thickness hinge area
IPC: F16B2/06
Filed: 1974-09-06
Abstract: This metal section is designed to form a retaining frame for panels of glass, wood or steel and is typically of anodised aluminium because the distortions of the frame during insertion of the panel are carefully localised and controlled so that cracking of the anodised finish is prevented or invisible. This is achieved by forming the section with a longitudinal groove (6). The groove may be at the inside junction of the web (2) and the central flange or double U section of may be external on the web. The flanges of the U are divergent, before assembly, so that the panel (4) with peripheral sealing strips (5) may easily be inserted into the frame. After insertion, a press forces the flanges to grip the panel, all of the distortion of the frame occurring in the weak section formed by the groove.

Abstract: The appliance is for stacks of paper, and consists of a conveyor, to supply the stacks in series; a packaging unit with vertically adjustable platform, to lift several stacks simultaneously, and deposit them in layers on a frame; and a unit, to displace the stacks horizontally from the frame. Each stack is deposited on a packaging material, in a packaging unit, which has a store for pre-cut blanks, moved under the stacks by a pneumatic suction element. The blanks and stack are moved to below a platform, and an additional plate presses onto the stack, to lower the platform, and erect the sides of the packaging, via fixed side ramps, acting onto the blanks. The semi-packaged stacks are moved horizontally onto the platform in a second machine, which has a store for cover blanks. The covers are places and formed similarly to the floor and the sides. A compressionor ejection system has a removable conveyor.

Title: Natural resonance frequency measurement by magnetostrictive bar - vibrates longitudinally by oscillations induced in coil coupled to bar
IPC: G01H13/00
Filed: 1975-04-17
Abstract: The measurement apparatus determines the natural resonance frequency of a magnetsatrictive bar vibrating longitudinally. A coil, coupled to the bar (13), is alternately connected to an oscillator (21) and a measurement circuit, during periods P and Q respectively, this being repeated periodically. The oscillations induced in the coil are passed to a first gate circuit (15) which passes them on only during the periods Q. A frequency multiplier (19) receives the oscillations from the gate circuit (15) and passes them to a second gate circuit (10) which only passes them on during a predetermined fraction R of each period W. A display counter (7) receives the oscillations from this gate circuit (10) and operates during a time period defined by a time base (2) stabilised by a quartz oscillator (1). This time base (2) controls the periods P, Q and the fraction R.

Title: Duct shaped simplified heat exchanger - has corrugated sheet between sides, ends blocked and two chambers
IPC: F28D9/00
Filed: 1975-04-29
Abstract: A heat exchanger has a duct-like casing (14) through which e.g. hot air is forced in one direction, and air heated by contact is extracted in the opposite direction. Each end of the duct is closed by a plate (15), with side sheets attached to a top sheet (17) and a bottom sheet (18) which are shorter than the overall length, so that a feed opening (20) and a delivery opening (21) are left at the top, while feed and delivery openings (22, 23) are similarly left at the bottom. The whole is divided into upper and lower chambers by a corrugated sheet (13) forming the heat exchange surface. Many variations on this basic design include ends shaped to guide the flows through the chambers, and different shapes, constructions and arrangements of the heat exchange sheet.
