Patent FR-2494899-A1 (FR)
Title: Magneto-mechanical converter for control relays - has soft iron core mounted between two like pole pieces and attracted by altering field strengths (HU 27.2.82)
IPC: H01F7/08
Filed: 1980-11-21
Abstract: The magneto mechanical converter allows relays to be made simpler and cheaper with straight forward manufacture using standard equipment. Such relays may be used over a wide range of parameters from milli amps and milli volts to kilo amps and kilo volts. They may be operated by direct current or alternating current at any frequency. For a well defined value of exitation current the elements of the converter can be adjusted to change position relative to each other very precisely in either action or reset. When the action current is reached it produces a movement with a large starting torque which may be used not only for opening and closing contacts but also for transmitting mechanical forces. Operation of the relay is not orientation dependent and a wide range of applications is envisaged in situations where control relays are used. The converter consists of a soft iron core with a permeability greater than 1.2 which is not energised, held on a flexible support between two like poles of two magnets which face each other and produce a variable magnetic field. In the rest position the core is held close to one pole piece and there is a null field in the centre of the pole gap. As the field strength of the one magnet is increased the null moves towards the core and the other pole piece, the core is demagnetised and remagnetised to be attracted towards the other pole. The field strength corresponding to the change of direction can be determined with great precision. Practical realisation of the device contain permanent and electromagnets with adjustable pole pieces and preconstrained springs.

Title: Supported silver catalysts with high surface area - for alkylene oxide prodn. by olefin oxidn.
IPC: B01J23/50
Filed: 1980-12-12
Abstract: New Ag-contg. catalysts have a wt. ratio of Ag. to refractory support of 20-60:100 and contain Ag. crystallites with an av. dia. of 80-600 Angstroms. The catalysts can be prepd. by impregnating the support with a soln. of an Ag. salt (esp. a carboxylate salt) and an alkali(ne earth) metal salt in an amine solvent contg. less than 20 wt. % H20. The wt. ratio of alkaline earth metal to Ag. is pref. 5-20:100 and the wt. ratio of alkali metal to Ag. is pref. 0.01-0.5:100. The support is pref. calcined silica or an alumina contg. more than 95% alpha-Al2O3; its specific surface is pref. 5-400 (esp 10-100) square m/g and its particle dia. is pref. less than 300 microns. Prodn. of E0 or P0 is pref. effected at a temp. below 210 deg.C and an 02/olefin vol. ratio of less than 1. The process is pref. carried put in a multi-tube pneumatic transport reactor with a reaction zone and a regeneration zone. The catalyst residence time in the reaction zone is pref. 5-60 sec. Regeneration can be effected with H2 or O2. The catalysts are esp. useful for prodn. of ethylene oxide (EO) or propylene oxide (PO) by vapour-phase reaction of ethylene or propylene with 02. Due to their high Ag. surface area, the catalysts have high activity, which can be maintained for long periods with frequent regeneration. Acceptable selectivity can be achieved by using moderate reaction temps. (120-210 deg.C).

Patent FR-2477268-A1 (FR)
Inventor: MOVA ANDREA
IPC: F23Q7/00
Filed: 1981-02-10
Abstract: Electric cigar lighters normally have a bimetallic gripper (20) which grips the edge of the heating element (22) in order to heat the cigar lighter and via which the current flows. If, because of a functional defect, the gripper (20) does not release the heating element (22), the cigar lighter overheats, leading to its destruction. In the case of known cigar lighters, a device is provided by means of which a short-circuit is produced whenever overheating occurs, which short-circuit causes the corresponding protection device to trip. In consequence, the defective cigar lighter is rendered inoperative, as well as all the other loads connected downstream of this protection device. In order to prevent overheating without causing a short-circuit, it is proposed to provide a spring arm (48) which rests with elastic stress on an insertion piece (54) (which melts at a predetermined temperature) and which interrupts the circuit, because of its springing movement, when the material melts.

Title: Catheter tube partic for entering passage in organ for transplantation - is flexible and conically tapered for cutting off to give suitable end dia.
Inventor: LOPEZ GEORGES
IPC: A61M25/00
Filed: 1981-05-22
Abstract: A transfusion catheter partic. for connection into arteries or veins of organs to be transplanted. The catheter is pitted at the end of a supply line which includes, in sequence, a reservoir contg. nutrient soln., a drop counter and a throttling clamp. The catheter itself takes the for of a conically tapering tube of flexible material, pref. plasticised P.V.C. The larger dia. end of the catheter is connected to the pipe from throttling clamp. The other end is cut off at a section which provides an outlet dia. to suit the passage size of the artery/vein to be supplied. The length of the catheter tube is pref. between 25 and 30 cm and its dia. between 1.8 and 5.5 mm. When the material from which the catheter tube is made is P.V.C., the plasticiser is pref. di(ethyl-2hexyl) phthalate or adipate. The method of using the new catheter is also claimed. This is a catheter for intravenous transfusions, esp. for supplying nutrient soln. to the arteries/veins of a living organ awaiting transplantation. The single cather tube can be instantly adapted to the exact outlet dia. required for insertion in any of a wide range of sizes of arteries/veins, thus obviating the need to stock many different sizes. The soft, flexible catheter is less traumatic than rigid versions.
