Title: Method for making a metal dental crown on a tooth supporting a clasp of a mobile apparatus
IPC: A61C5/77
Filed: 1983-11-25
Abstract: The production of a metal dental crown on a tooth supporting a clasp of a mobile prosthesis, may be performed with the technique hereinbelow in two sessions. It does not deprive the patient of his/her prosthesis; it does not lead to re-making of the prosthesis or of the section of the clasp. The originality of the technique consists in the order of the operations during the first session. After having withdrawn the mobile apparatus, taken the initial impression of the tooth before it is cut; packed the impression with a self-calcinable resin, and applied it onto the prepared tooth; the resin is sent to the laboratory, for casting in metal which will be sealed in the mouth during the second session. This concept of a prosthesis reconstructing a shape and a topography identical to the initial tooth has required a new word, not found in dictionaries, to be coined, namely an "isotopic crown".

Title: Independent and continuous electrical generator using flywheels coupled to motor-alternator sets
IPC: H02K53/00
Filed: 1983-12-23
Abstract: The invention relates to instruments of the electrical generator type operating independently and continuously. It comprises a single spindle on which are interposed electrical generators A1, A2, electric motors M1, M2, M3 and inert masses in the form of flywheels V1, V2, V3, V4, which provide kinetic energy. Causing the assembly to rotate produces electrical energy, given that the entire assembly system constitutes only one single body. With regard to the initial energy for obtaining mechanical energy, the start-up is provided by an air turbine T1 which is only an auxiliary part of the assembly, then the transfer of mechanical force is provided by the motors which, when their power is reached, are supplied with necessary electrical energy and assisted by additional energy coming from the development of the kinetic energy of the inertial masses in the same body of the assembly. With regard to the distribution of electrical energy for the continuity of the motion and the full power of the motors to ensure the rotation of the assembly at X revolutions per minute, this is provided by the various generators which supply their energies individually. A gas turbine T2 in closed circuit provides the full power of the device.

Title: Process for the preparation of saccharified cereals using the enzymes arising from whole cereal grains and cereals obtained by this process
Inventor: FULGER CHARLES VON
IPC: A23L7/157
Filed: 1984-01-19
Abstract: Process for the production of an entirely natural, enzymatically saccharified cereal arising from the whole grain. It consists in milling and separating the whole grain in order to produce a bran fraction, an endosperm fraction and a germ fraction. The germ fraction is treated by toasting and milling and preferably by removing the bran before toasting. The bran fraction and the bran optionally separated from the milled germ are modified in order to increase their functionality either by high-temperature extrusion, under high pressure, or by milling to a particle size of 5 to 100 <0>m. The endosperm fraction is crudely milled, brought to the form of a solid/liquid mixture, cooked and then hydrolysed enzymatically. The final stage consists in recombining the treated fractions in order to form a cereal pulp which is subjected to a later treatment in order to produce a ready-to-eat breakfast cereal. If desired, the cereal pulp can be malted and then have added to it from 1 to 15 % of the whole grain.

Title: Method and equipment for mining steep mineral seams, particularly coal seams
Inventor: MEREI E
IPC: E21D23/00
Filed: 1985-09-19
Abstract: The invention relates to a method and equipment for mining steep mineral seams, particularly in collieries. Horizontal directional roads 14 which cross each other and an inclined road 16 connecting them, formed at the beginning of the mining cycle and having advantageously an inclination (slope) which is equal to the mean slope of the seam, are created at different levels in essentially parallel and horizontal cross-cuts 13. A complex of machines 24 for the mechanical mining and the cutting of the advancing long wall as well as the transport are then installed in the gate road placed below the upper directional road 14 and following the inclined road 16. The gate road is connected by an excavation to the upper directional road 14 in such a way that the advancing long wall and the panel entry are thus continued in a known manner. The connection between the gate-end road and the upper directional road 14 is ensured in continuous fashion by extending the excavation, and the obtained mineral matter is conveyed via the inclined gate-end road 16 to the lower directional road 14 or towards the transporter device located therein.

Abstract: The invention relates to a device making it possible to release, in the event of snow fall or frost, a straight foot which reinforces the supporting structures of greenhouses and avoids damage to the latter. It consists of two jaws 1, fastened by two arms 3 and 4 to the arch 2. A straight foot 5, fitted with a plate 6, is articulated to the neighbouring arch 7 by means of an assembly consisting of a pin 9 and of a support 8. When, under the action of a vertical force caused by snow or frost, the arch 2 sags slightly, the two jaws 1 move apart and release the straight foot 5 which positions itself just above the ground and supports the arch 7. Replicating this device on all the arches of a greenhouse makes it possible to safeguard all the supporting structures of this greenhouse. The device according to the invention is intended in particular for the market garden industry.
