Patent FR-2297453-A1 (FR)
Title: Liquefied gas level regulator - maintains constant liquid level in heated vaporiser
IPC: F17C13/02
Filed: 1975-01-08
Abstract: Liquefied gas is heated in a vaporiser to feed a burner. A fixed level of liquid is maintained in the vaporiser for varying gas demand. The thermostatically controlled heating resistors which vaporise the liquid also heat an expandable element which opens a spring-loaded valve controlling the input of liquid. The expandable element is partially immersed in the liquid so that as the level of liquid falls due to evaporation more heat is applied to the element, the element itself can be used to regulate the current to the heating resistor.

Patent FR-2262712-A1 (FR)
IPC: D06L3/02
Filed: 1975-02-27
Abstract: The softening agent has a lasting and antistatic action on washing. It contains as active components any desired inorganic peroxo bleaching agent and a cationic softening agent, nitrogen-containing compounds being preferred. The weight ratio of the bleaching agent to the softening agent is 17:1 to 1:4. The joint use of cationic softening agents and an inorganic peroxo bleaching agent leads to an unexpected synergistic cleaning effect, the softening properties being enhanced. The said agent is preferably employed for the softening and bleaching of cotton textiles or of textiles based on cellulose fibres such as rayon or other textile fibres such as nylon, silk, wool, polyethylene terephthalate, cellulose acetate, acrylonitrile polymers or copolymers or blends or blend fabrics, such as, for example, cotton/polyester textiles.

Title: Two-cam rotary locking bar for cardboard cutting machine - is rotated to lock form blade alternatively to oscillating or static platen
IPC: B26D7/26
Filed: 1976-05-06
Abstract: The bi-cam rotary locking bar (6-9) is for use on an oscillating platen (1) cardboard cutting machine. The machine has a static platen (2) which supports an interchangeable form-blade (3) during cutting. The bar (6-9) can lock the form (3) to either platen (1, 2) and, thus, the mobile platen (1) is used to lift and present the form (6-9) to the static platen (2) during form change. To mount a form, platen (1) is moved to the horizontal. The form is then placed on platen (1), centered by lateral brackets, and secured by the locking bar. Cam (7) of the locking bar engages an end wall (10b) of a semi-circular channel (10a) in the head (10) of platen (1). Next, platen (1) is moved to the vertical presenting the form to platen (2). Cam (8) enters a top-reamed socket (11a) in the head (11) of platen (2). A radial lever (9) is then used to rotate the bar (6) half a turn causing cam (8) to engage and cam (7) to disengage.
Patent FR-2313751-A1 (FR)
IPC: H01B17/40
Filed: 1976-06-03
Abstract: The ceramic insulators have a bevelled glazed clamping bead for electrical high-voltage apparatuses. By means of a tensioning screw (2) whose axis is at right angles to the clamping bead surface, a clamping shoe (1) (which is provided with a threaded hole) is, on the one hand, drawn against the clamping bead (3) and, on the other hand, is supported by means of its supporting feet (4) on a metal fitting (5). This armature has outwardly open slots (5b) (distributed uniformly over the entire circumference) into which the tensioning screws (2) are inserted. The bearing surface (5a) on which the head of the tensioning screw (2) is supported runs parallel to the bearing surface of the clamping bead (3), which is provided for absorbing pressure. Since the clamping shoes (1) can be pushed into outwardly open slots (5b) of the metal fitting (5), the large diameter tolerances of the glazed ceramic insulator are compensated for.

Title: Prevention of pipe formation in ingots - using spheres of insulating or exothermic material, gives fewer surfaces defects
IPC: B22D27/06
Filed: 1976-08-27
Abstract: Pipe formation in ingots of esp. steel is prevented by placing an exothermic and/or insulating compsn. in the form of 'spheres' on the bottom of the mould. The 'spheres' are pref. not absolutely spherical and have a dia. of about 1-3cm. The material from which the spheres are made is pref. an insulating or exothermic material and the binder is pref. a cement, a silicate, a glue or a synthetic resin. The 'spheres' are able to roll and are not caught by the sides of the mould as sometimes a covering cap is when the steel is poured in. Fewer surface defects result and hence fewer refections.

Title: Call signal assigning device - is used for address controlled signal transmission to rail vehicles and has different call signals for different track sections
IPC: B61L25/04
Filed: 1976-12-01
Abstract: The call signal is used within the area of a track station for connection build-up between the track station and rail vehicles. Switching means are provided, which deliver an engaged signal when the vehicle (F) enters the track station (S) area, and a free signal when the vehicle (F) leaves the track station (S) area. A signal transmission system is provided at each entry section (B). It assigns to each rail vehicle with communication equipment (F) a call signal from a number of available call signals and is controlled by the engaged signal. When the vehicle leaves the track section, its call signal is returned to the list of available signals.

Title: Abrasive sheet has spherical granules comprising bonded grains - with soft adhesive to give uniform wear without loss of roughness
IPC: B24D3/00
Filed: 1977-02-25
Abstract: A grinding or abrasive agent on an underlay comprises spherical grinding granules bonded to the underlay and each comprising a large number of abrasive grains. The spherical granules contain the abrasive grains embedded in an organic binding agent matrix, the hardness of which is not harder than the normal binding agent which is used for bonding the spherical granules to the underlay. Pref. the spherical granules contain 80-97% of abrasive grains and 3-20% of organic binding agent matrix. Up to 60% of the organic binding agent matrix may be replaced by fillers. The organic binding agent matrix pref. comprises a phenol formaldehyde resin, urea formaldehyde resin or malemin resin. The mean dia. of the spherical granules is pref. 300-2000 mu and is 3-500 times the mean dia. of the abrasive grains. A high, uniform grinding performance accompanied by a long-lasting roughness depth is obtd. without a tendency to become prematurely clogged. Due to the relative softness of the binding agent between the abrasive grains in the spherical granules, the abrasive grains are continuously and uniformly exposed to provide the grinding action, without a risk of the surface of the workpiece becoming scratched, since the granules themselves do not act as a large abrasive grain.

Title: Coatings removal, esp. detinning tinplate with lacquered coatings - by ultrasonically treating before tin removal
IPC: C22B7/00
Filed: 1977-03-04
Abstract: Removal of multiple coatings consisting of >=1 outer organic chemical coating and an inner metal coating from metal objects is described. The objects are treatd in a first soln. in which they are subjected to an ultrasonic field which more or less removes the outer organic chemical coating. The objects are then treated in a second soln. which removes the inner metal coating. Process is esp. sued for treating lacquered tinplate waste. The rate of detinning as well as the amt. of Sn recovered is increased. The metal objects are cooled to a brittle temp. and the non-ferrous particles born by the ferrous objects or fragments are removed in their cooled state by a magnetic device or a vibrating or shock mechanism. The organic chemical coating is a paint or a varnish e.g. acrylic or phenolic. The soln. for removing the Sn-based coating contains NaOH. The objects may also be subjected to an ultrasonic field whilst they are in or passing through the caustic soln. The ultrasonic field acting on the objects in the first or second soln. may comprise two different frequencies. The first soln. may be aq. and contg. a liq. degreasing agent e.g. an alkaline detergent.
