Title: Thin film piexo-electric resonator - operates in 400 Mhz to 1 Ghz range, is mounted on substrate and has gold electrodes
IPC: H01L41/45
Filed: 1975-05-29
Abstract: Thin film piezo-electric resonator, electrically excited, setting up a longitudinal and a transverse mode vibration. The upper frequency limit is around 1GHz using film about 10 microns or less thick. The resonator is carried on a silicon or ceramic substrate (1) having a through hole (2) about one millimeter in dia. Over this is laid a several angstrom thick film (3) followed by an insulating layer (4) possibly SiO about 5000 angstrom thick. Above this is positioned a CdS or ZnO piezo-electric element (6) sandwiched between 1000 angstrom Au electrodes (5, 7). The piezo-electric thickness is determined by the working frequency required. The polymer layer is depositied chemically on glass and floated off this in a water bath.

Title: Pulse impact tool for finishing internal cylindrical surfaces - has groove and cage for different dia balls moved by fluid press
Inventor: YASCHERITSYN P I
IPC: B24B39/02
Filed: 1975-06-23
Abstract: The tool for finishing the internal surfaces in blanks includes a casing having a groove on its side surface for accommodating balls which are moved by a fluid pressure. A fluid is fed in through channels in the tool casing, the channels putting the groove in communication with the source of fluid under pressure. The groove is surrounded by a cage accommodating working elements which are installed with a provision for contacting the bodies of revolution and colliding with them in the operating tool. During this collision the working elements produce plastic deformation of the machined surface.

Title: Phosphonocarboxylic acids and-chelates - useful as micronutrients for plants
IPC: C07F9/02
Filed: 1975-07-18
Abstract: Micronutrient fertilisers used to provide plans with elements of Atomic No. 24-30 contain >=1 phosphonocar-oxylic acid of formula (I) (in which R = H, alkyl (1-4C) or -CH-CH-R3; R1 = H, alkyl (1-4C) or carboxyl; R2 = H or methyl; and R3 = cyano, carbonamido or carboxyl). The chelate complexes of (I) with ions of elements Cr, Fe, Co, Ni, Cu and Zn are novel compounds, and (I) is a known compound but its use as micronutrient is novel. Preparations contg. (I) may be used in cultures such as citrus fruits, fruit, vines, hops and vegetables, as well as for a large variety of garden- and pot plants. They may also be used against various plant diseases caused by lack of trace elements. The Fe-complexes of (I) are esp. suitable against chlorosis.

Title: Increasing the silica content of zeolites - to obtain acid gas absorbers and catalysts with higher operating temps
IPC: B01J20/18
Filed: 1976-03-09
Abstract: Process for increasing the mol. ratio SiO2/Al2O3 in the crystal lattice of zeolites, by the removal of water using air or inert gases and then treatment at high temp. with gases contg. chlorine cpds. The novelty is the use of a reactor provided with at leat one opening and in which zeolites with mol. ratio SiO2/Al2O3 below 5 are heated to min. 400 degrees C. in the presence of air or inert gases, and are then subjected to flowing gases, contg. Cl2 or HCl, at 400-700 degrees C. The initial zeolites pref. have a mol. ratio below 4.75, and the treatment is pref. undertaken at a total pressure above 1 absolute atmos. The pref. zeolites are employed in their alkali(ne earth) form, possibly with partial or complete replacement by hydrogen ions. Zeolites rich in SiO2 have improved high temp. stability and better acid resistance; they are very suitable as catalysts for the alkylation or isomerisation of hydrocarbons, or the adsorption of acid gases.

Title: Direct closing tap for fire extinguishers - has pyrotechnic bolt allowing opening under pressure of medium on firing
IPC: F16K17/38
Filed: 1976-07-22
Abstract: The direct-closing tap is pyrotechnically operated, being particularly for use in fire extinguishers. It has a body (2) in which a plug (7) sliding axially bears against a seat in the closed position, the plug being fixed to a stem extending axially on the other side of the seat. A pyrotechnic bolt (12) is fixed in the body, and onto it is screwed a tubular piece (11) bearing against the stem. The tap is opened and shut by screwing or unscrewing this piece. On firing, the part of the bolt onto which the tubular piece is screwed is detached from the body, releasing the piece and thus the stem. This enables the plug to open under the pressure of the fluid the opening being spring-assisted if desired.

Patent FR-2364931-A1 (FR)
Title: Prepn. of hydroxy-telechelic polymers of average mol. wt. 1000-20,000 - by radical polymerisation in an alcoholic diluent
Inventor: BROSSE JEAN-CLAUDE
IPC: C08F2/06
Filed: 1976-09-17
Abstract: In a new process of preparation of hydroxytelechelic polymers of average mol.wt. 1000-20000, monomers susceptible to radical initiation are polymerised in presence of a peroxide-alcohol system as catalyst in an alcoholic diluent, under pressure, at a temp. of 100-140 degrees C, with stirring. The operating conditions are such that the nature of the alcoholic diluent, the duration of reaction and the efficiency of stirring are chosen so that the alcohol does not act as a precipitant in the reaction medium. Normal method of prepn. of hydroxytelechelic polymers, in a reaction medium consisting of a mixt. of water and one or more alcohols forming an azeotrope with it, leads to prods. of a wide range of mol. wts.., so that fractionation is needed to separate out the polymers of fairly low mol. wt.. The present method, in which the rate of stirring influences the rate of the alcohol, prevents the formation of high polymers and therefore obviates the need for a fractionation procedure.
Patent FR-2326676-A1 (FR)
Title: Effective range increasing system for projectiles - guides projectile suddenly by sequence of pulses into target area
Inventor: MOLITZ H
IPC: F41G3/06
Filed: 1976-09-23
Abstract: The system is used for increasing the effective range of projectiles against individual targets. The trajectory is corrected on a relatively short section of trajectory on direct firing and can be made in the middle of the trajectory of the rotating projectile. The trajectory is suddenly changed by exerting a pulse on the projectile centre of gravity. This pulse guides the projectile, which would otherwise hit the vicinity of the target, into the target area. The correction is made at the observed point relative to the theoretical point through which the uncorrected projectile would pass for hitting the target. The magnitude of the pulse is kept preferably constant and only the direction of the correction pulse is varied.

Title: Rotary internal combustion engine - has rotor disc with venturi passage between air inlet and outlet openings
IPC: F02B53/04
Filed: 1976-10-14
Abstract: The motor has a casing forming a circular cylinder. The rotor (2) is in the form of a disc on the end of a shaft (2') and revolves in the cylinder. The rotor disc has air inlets (Oa) on one side. Each inlet communicates by means of a passage (P) within the disc with an air outlet (Oe) on the other side of the disc. The passage is in the form of a venturi and fuel is admitted to it at the venturi throat. The fuel enters through channels in the shaft (2'). The fuel air mixture is discharged from the air outlet into a combustion chamber in the cylinder. The reaction of the burning gases on the rotor disc produces the turning moment.

Title: Internal combustion engine using two fuels - has propane introduced into cylinder and compressed adiabatically before addition of water
IPC: F01K25/06
Filed: 1976-12-23
Abstract: The engine has a piston reciprocating in a cylinder as in a conventional diesel engine. At the bottom of the stroke a quantity of propane is admitted into the cylinder. It is compressed (1-3) adiabatically and a quantity of water is then injected. Because of the difference in specific heats the pressure rises further (4) with almost no change in volume. The mixture then expands adiabatically to a pressure below the starting pressure. A further amount of propane is admitted at the bottom of the stroke to bring the pressure back to the starting point (1). In this way an Otto cycle for the water is combined with a Carnet cycle for the propane.
