Title: Multiple jaw precision chuck - has cage enclosing jaws together forming variable prismatic chamber controlled by screw
Inventor: BROUEL SERGE
IPC: B24B41/06
Filed: 1976-05-26
Abstract: The precision chuck is for use in sharpening drill bits. It comprises a cage enclosing the jaws, which between them form a variable-size chamber accommodating the work. This chamber is of straight prismatic section, with a regular polygonal base. Movement of the jaws can be by a screw engaging in a tapped hole in one of them, which acts as the master jaw, and causing this jaw to slide in the cage. Each jaw can have one face bearing against the inside of the cage, one bearing against each of the adjacent ones, and one free face.

Title: Ladle stopper coated with vitrifiable layer - prevents metal solidification and blockage at ladle orifice
IPC: B22D41/16
Filed: 1976-07-06
Abstract: A ladle stopper comprising a rod with a refractory tip is coating based on inorganic refractory particles immersed in an organic or inorganic binder. The nature and compsn. of the particles is such that at least the surface of the coating is vitrified when contacted with the liq. metal. The stopper may be used in tundishes, ladles etc. The thickness of the vitrified layer increases with the contact tune and the layer prevents degradation of the thermal insulation and it is retained during the entire casting operation. The thermal insulation prevents solidification between the lade stopper and orifice and consequently prevents partial or total blockage of the orifice by the metal.

Title: Liquid esp. pre-fermented milk fed into vessel - without turbulence through surface grating below distribution rotor (NL020277)
IPC: A23C9/12
Filed: 1976-07-29
Abstract: A device for feeding a liq. onto a liq. surface with minimum mixing comprises a grating at the liq. surface and a vertical-axis just above the grating consisting of radial tubes having horizontal tangential liq. distribution outlets at intervals along them. The liq. is thus distributed onto the grating and descends to the liq. surface below with an absolute minimum of turbulence. The grating pref. consists of tubes or rods which are rounded at least on the upper side in partic. of a raft of floating hollow tubes. Used for the prodn. of yoghurt or other milk products in a coagulation vessel. The interposition of the grating between the distribution rotor and the liquid surface reduces the disturbance to that surface to an absolute minimum.

Title: Detection of added hydrocarbons in petrol and light oil - by incorporation of colourless chromogenic substances
IPC: G01N31/22
Filed: 1976-09-03
Abstract: Method comprises incorporating in the added hydrocarbons after their prodn. a colourless reducing chromogenic substance, which developes a colour on contact with an oxidising agent. Also equipment for carrying out the test, consisting of a transparent tube contg. a layer of oxidising agent is claimed. Process is a simple, accurate, test requiring no special equipment or skill. A strong colour is developed, so that amt. of additive needed is small. A large sample can be drawn into the equipment, which is easily calibrated to show the amt. of cheaper blending agent present. In an example, 800 ml petrol is mixed with 200 ml benzene contg. 1 mg/l crystal violet lactone. Application of 6 drops to a TLC silica plate with drying of each produces a brilliant blue stain.

Title: Safety pneumatic tyre has freely revolving support ring - to carry load when deflated resting in channel section seating
IPC: B60C15/028
Filed: 1976-09-27
Abstract: Safety assembly comprising pneumatic tyre and wheel rim has a safety, load-bearing component of annular form between the beading and serving for accepting load when the tyre is punctured. The load-bearing component comprises a number of curves segments of rigid material connected together end-to-end. The whole of this load-bearing component rests on a sliding ring of rigid material and of U-section, which thus forms a seating in which the load-bearing component is free to revolve. The sliding ring is centered axially by guide rings, mounted on either side of the sliding ring and bearing against the inner faces of the beadings. The sliding ring is constituted of two or more segments, joined end-to-end. The guide rings, in the embodiment shown, are integral with the sliding ring. In a variant these guiding rings are separate rings on either side of the sliding ring. These separate rings may be of elastic material, esp. rubber. Between the sliding ring and the load-bearing component there may be a coating of low friction material, esp. PTFE.

Title: Increase in light energy transmission of optical fibre - includes introduction of cone of light to fibre having quasi-parabolic index profile
Inventor: JACOMME LOUIS
IPC: G02B6/42
Filed: 1976-10-21
Abstract: A process for augmenting the monochromatic incident light energy in an optical fibre (31) consists of injecting monochromatic light energy of wavelength (lambda) along all points of the entry face (34) of the fibre. A cone of light is introduced whose axis is parallel to the axis of the fibre (zz') and who apex angle (u) is several degrees. The variation of the refractive index of the light as a function of distance (r) from the axis of the fibre is called the index profile n(r), and is given by the expression n2(r) = no2 (1-2 DELTA (r/a) alpha) where no is the index along the axis of the fibre, DELTA is a constant is approx. 10-2 and alpha is a constant between 1.98 and 1.99. The index in the sheath surrounding the heart or core (11) of the fibre is given by n2(a) = no2 (1-2 DELTA).

Title: Fluid flow rate transducer - uses obstruction induced vortices to measure frequency representing flow rate
Inventor: GUILLERM HENRI
IPC: G01F1/32
Filed: 1977-03-18
Abstract: An accurate industry orientated fluid flow transducer is such that obstruction is placed in the fluid flow path so that eddies or vortices are formed and the frequency of these measured to give a measurement of the fluid flow rate. A rectangular or trapezoidal obstruction (11) is placed in the flow path of the fluid in a pipe section (10), so that vortices are formed in the fluid as it flows over the sides (20, 21) of the obstruction. Liq. filled ducts in the obstruction, transmit alternating pressure signals caused by these vertices via flexible leads (30, 31) to a pressure difference transducer (32) and thence to via a monostable multivibrator (34) to a frequency measurement network (35) and display (36). Membranes isolate the internal obstruction liq. from the fluid under examination.
