Title: Drill bit for marking hole centre for boring bit - has two radial cutting edges with perpendicular trailing edges lagging radii
IPC: B23B51/02
Filed: 1977-03-11
Abstract: The cylindrical drill bit (1) is used for marking the centres of holes in advance of drilling by a conventional helical drill bit. The marker bit (1) has two helicoidal grooves (2) with two radial cutting edges (4, 5) which lie in a common diametric plane (6). The cutting edges (4, 5) are formed by the intersection of the conical surface to the tip of the bit with one edge of the respective groove. The intersection of the trailing edges of the grooves with the tip surfaces may form arrisses (7, 8) which align perpendicular to the main cutting edges (4, 5). The arrisses (7, 8) however, are not truly radial, but lcoate nominally beyond a parallel line (9) which lies within the groove concerned. The cutting edges and the trailing arrisses of each groove may be joined by parallel inclined surfaces (10, 11). The two surfaces form a slender blade incorporating the point (13), and the angle of conicity of the bit may be 10 deg. less than that of the drill bit that follows.

Patent FR-2393307-A1 (FR)
Title: Immunological determination and detection procedure - in which immunoactive substances are immobilised on a solid phase before subjecting to the immunological reaction
IPC: G01N33/58
Filed: 1977-05-31
Abstract: Detection and quantitative determination of immunoactive substances in liquid samples of biological materials comprises immobilisation of the samples (or the substances therein which are to be detected) on a solid phase before carrying out the immunological reaction. The precision and sensitivity of the procedure are higher than those of conventional procedures. Immobilisation of the substance(s) to be determind reduces costs and improves the speed and simplicity of determinations. In determinations of dangerous substances such as hepatitis B antigen, the immobilisation eliminates the risk of exposing laboratory personnel to possible infectious material. In an example the new procedure is applied to the determination of hapatitis B antigen by immunofluorescence assay. The blood sample to be tested is diluted with saline and applied to a synthetic fibre material. After drying, the material is immersed in acetone for 5 mins. to fix the immunoactive substances on the fibre.

Title: Safety switch for gas burner - has interlock with ignition and water valve holding gas supply open
Inventor: MULSANT PHILIPPE
IPC: F23N5/24
Filed: 1977-07-18
Abstract: The safety and control device is for a gas burner supplying instant hot water to a bath and without a permanent pilot flame. A tapping from the gas main supplies a temporary pilot flame, whose ignition is controlled by a water valve. A low-inertia heat-sensitive component acts via a small valve on the control diaphragm of a mechanism simultaneously actuating the gas valves for the burner and pilot flame. This mechanism is held in the position admitting gas to the burner by an additional device interlocked both with the burner ignition and the opening of the water valve. The device can be a thermocouple circuit near the flames from the burner. This acts via an electromagnet on a plate coupled to the mechanism.

Title: Positive and negative control of beam unrolling motion - by differential wheels synchronised to warp and fabric length
IPC: D03D49/06
Filed: 1977-09-28
Abstract: A mechanism for giving control over the unwinding of a wrap comprising a web of threads wound on a beam in a loom or warp knitting frame, having a take up roller for the fabric and >=1 beam, includes a differential, acting as a comparator between the length of the fabric produced and the length of warp let off by the beam motion, which generates variations in pressure in a pneumatic system, by the opening and closing of a valve. In the differential, the rotation of one of the planetary gears is controlled from the fabric take up roller, whilst the other planetary wheel is regulated by the linear unrolling of the wrap threads. The system can be adapted to most existing beam let off motions, converting them to positive operation, i.e., so that they let off a length of warp which is determined by the design of the fabric. There is always the possibility of negative control if the technical conditions call for it.

Title: Strip profiles for linking the main components of an inflatable raft - shaped to ensure that joints are stressed in tension, not in shear
IPC: B63B7/08
Filed: 1978-01-05
Abstract: An inflatable raft comprises twin tubes of impermeable fabric mounted one on top of the other by fusion-bonded spacers having slightly splayed channel profiles. The floor and roof of the raft etc. also of flexible impermeable fabric secured partly by bonding directly to the main tubes and partly by bonding to ancillary dihedral section profiles also bonded to the main tubes.
