IPC: A61Q9/02
Filed: 1973-10-15
Abstract: Novel compsns. consisting of quaternary halides of trialkyl or hydroxyalkyl amino alkyl gluconamides are excellent emollients having high substantivity for skin. They are prepd. e.g. by condensation of delta-gluconolactone with gamma-dimethylaminopropylamine and the resulting gluconamide is quaternised by reaction with an alkyl halide or hydroxyalkyl halide.
Patent FR-2213084-A1 (FR)
Title: Centrifugal separator for dust laden gas streams - having direction change which induces vortex in chamber and concentrates dust into smaller stream
IPC: B01D45/16
Filed: 1973-11-30
Abstract: The device has >=2 vortices one above the other with central extraction pipes for the air. The chamber is located at a change of direction in the gas stream with sharp leading and trailing edges on the chamber. The change of direction induces storng centrifugal flow patterns in the chamber. The majority of the air is extracted from the centre of the chamber. Dust entering the chamber spirals towards the centre and is then thrown out by centrifugal force and returns to the main outlet stream in the duct. This represents a very marked concn. of the dust and the air extracted from the centre is virtually dust free.

Title: Balance weight for vehicle wheel - has two outer and one inner point contact areas with wheel
IPC: F16F15/32
Filed: 1974-04-22
Abstract: A balance weight incorporates a means of immovable attachment to the edge of the rim of a vehicle wheel and provides three contact areas (11, 12, 13) which, viewed in a radial cross-section, are practically point contact areas, of which two (11, 12) make contact with the extremity (1") of the edge of the rim (1) and are positioned on neighbouring radii relative far away from the axis of the rim. The third (13) makes contact with part (1'") of the edge of the rim (1) radially within the extremity (1") of this edge, the three areas (11, 12, 13) being maintained in contact with the edge of the rim by the immovable attachment (20).

Title: Automatic stacking device for thin objects - such as skins which are deposited at nil speed
IPC: B65H29/36
Filed: 1974-05-08
Abstract: Automatic appts. for depositing stacking thin objects, notably skins, is of the endless belt type. It comprises an endless belt by which the skins arrive and a table on which the skins are stacked. The framework is mounted to pivot around the horizontal axis so that the fornt part of the appts. above the table, can be raised or lowered in the direction of the arrow, this portions carries the components specially intended for the deposition of the skins. By choosing the speed at which the skins arrive they can be stacked in the simplest manner or alternate sheets can be reversed so that the fresh side is placed against the flesh side of the next skin or with two hair sides together. When the stack becomes too high the beam of light from the source to the photocell is cut, this causes the framework to rise in proportion as the skins are stacked, so that the latter are always correctly deposited. Other parts of the appts. are controlled by photocells. The depositing belt has a 'fixed' zone so that its speed when depositing a skin is nil. Its various movements are always in the same direction and at the same rate as the feedin means.

Title: Mixing granular materials and binders - using a split batch and non-uniform mixing to reduce amt. of binder required
IPC: B22C5/04
Filed: 1974-06-07
Abstract: Process for making a granular or powdered mixt., such as foundry sand; a refractory or abrasive product; marble powder; gravel; or e.g. any constructional material, where a binder or binder plus hardener is used for agglomeration. The novelty is that a mixer is used to make a premix using a first fraction of the charge and all the binder plus any hardener; after through mixing so the binder has formed a film on all the grains in the fraction, the remaining fraction of the charge is added very rapidly and the mixer is then immediately emptied to prevent the binder from coating all the grains in the second fraction. The amt. of the charge added in the premix is pref. 40-70% esp. 50-60% and the pref. plant includes a rotary screw mixer. In the case of foundry moulding sands, the amt. of binder required to attain a given strength is reduced, thereby reducing the cost of the mixt.
Patent FR-2274152-A1 (FR)
Title: Overhead power cable sleeve drawing die - operates by hydraulic pressure for cable connecting sleeves
IPC: H02G1/14
Filed: 1974-06-07
Abstract: A wire drawing unit for power transmission cables has two main parts. The first is a die carrier (1) that is split and pivoted so that the die (3a) can be closed around a cable sleeve (20). The other part has gripping jaws that are profiled to grip the sleeve. The two parts are joined together by hydraulic pistons operated by an external compressor connected by a flexible pipe (13). The pistons cause the jaws to operate first, then the two parts of the unit are pushed apart which causes the die to draw the sleeve. This improves existing designs as it only needs one operation and can be used at heights.

Title: Wall covering or screen fabric comprising non-woven web - stitched with yarns which are contracted to form corrugations
Inventor: POYET ROGER
IPC: D04H1/52
Filed: 1974-07-15
Abstract: A wall or ceiling covering fabric, or a fabric for a screen comprises a non-woven fibrous mat in which lines of stitching are formed from synthetic yarn which is capable of contraction. The stitching forms a zig-zag pattern on the reverse face of the mat and a straight line on the front face of mat. After stitching the yarn is contracted so that it causes the mat to form corrugations between the lines of stitching on the front face. The fabrics is easy to fix in position and cheap to produce. The fabric may be made from glass fibre mat and is therefore inflammable.

Title: DC transmission line excess voltage protection - comprises excess voltage eliminator across thyristor gate to protect rectifiers
IPC: H02H9/06
Filed: 1975-06-23
Abstract: A method for protecting rectifier for d. c. transmission lines from excess voltages, includes application of an excess voltage eliminator with series connected ballast resistor. The thyristor gate of the rectifier is allowed to be triggered once at the response-time point of the eliminator, and then the normal operation of the rectifier is re-established. This method of protecting transmission lines results in a reduction of the time during which the consumers power supply is interrupted in response to the eliminator action in preventing excess voltages.

Title: Obtaining blood sample using cannula and evacuated vessel - having adjustable flow valve and second valve on cannula
IPC: A61M5/34
Filed: 1975-08-21
Abstract: A blood sample is obtd. by a cannula which extends from a housing including a first valve normally obstructing a discharge port leading to the cannula. An evacuated vessel includes a valve mounted within its neck and operable by rotating the container w.r.t. a conduit extending axially from the neck. This conduit can enter the discharge port of the cannula housing to provide a fluid-tight connection but also simultaneously opening the first valve to allow connection between the cannula and container valve. The appts. is used to obtain a blood sample by first inserting the cannula into a blood vessel then attaching the container with its valve still in the closed condition. The valve is then opened and blood enters the container. Evacuated containers can be used sequentially by coupling into the cannula and the first valve automatically seals the blood discharge between connections. The flow valve associated with each container can be opened partially to test whether the cannula has correctly entered a blood vessel and if unsuccessful the valve can be closed immediately to prevent the formation of a haematoma.

Title: Casing for cigarette lighter - has hinge with pin rotating against spring and rear edge contacting fuel valve operator
IPC: F23Q2/40
Filed: 1975-11-13
Abstract: The lid is shaped to match the lighter casing and closes along a flange (6) of the casing. The lid is hinged about a pin (10) which rotates against a spring (16) fixed to the casing. The spring (16) will cause the lid to slap shut after use. The back edge of the lid comes into contact with the plate (22) when it opens. The plate terminates in a fork (25) which fits under the fuel valve. The fork lifts the valve open as the lid opens and closes the valve when the lid is closed.
