Title: Corrugated horn antenna - operates over several frequency bands by including long and short grooves cut into wall
Inventor: BUI-HAI NHU
IPC: H01Q13/02
Filed: 1979-05-04
Abstract: The antenna horn is usable over a frequency range of greater than one octave is of the corrugated horn type and has a number of internal grooves (A,B) whose depth decreases from the horn throat to its mouth. The grooves are alternately long and short with a width that increases linearly towards the mouth, the wall thickness between adjacent grooves decreasing towards the mouth. The mean depth of the long grooves is greater that that of the short grooves. The horn has infinite surface admittance in its mouth and operates in a hybrid equilibrium mode with a radiation diagram having a symmetry of revolution and a low level of diffuse lobes. The grooves provide a low reactance at the throat cone transition of the horn, which can operate over a number of frequency ranges e.g. two covering more than an octave between the lowest and highest frequencies.

Patent FR-2457163-A1 (FR)
Title: Caulking machine oscillating chisel - has front tooth to cut up chips for easy removal from recess
IPC: B27G13/12
Filed: 1979-05-22
Abstract: A chisel capable of oscillation, such as a cross chisel, for use on caulking machines, has a device, or more than one, on its leading side (a1), for cutting up the chips (f) formed by the tool (a) in the course of working. This prevents firm settlement of chips in the recess (d) provided, and makes their removal easier. The leading side can be fitted with one or more protrusions (e)with a cutting edge (e1) to cut chips against the adjacent slit side, reducing their size. It can form a tooth, with cutting edge vertical to the tool's other teeth. Simple construction ensures reliable chip removal.

Title: Screw cap bottle closure moulded with integral security lip - for containing carbonated drinks
IPC: B65D41/34
Filed: 1979-05-31
Abstract: A moulded cap for sealing the mouth of an externally threaded bottle is moulded with an integral security lip with several internal teeth having a shallow internal chamfer leading to a face undercut at about 45 deg. The lip is connected to the cap by several radial ribs having a radial thickness less than their peripheral width. The cap is sealed by an annular pad of relatively soft material located beneath the crown of the cap. Suitable for sealing bottles contg. carbonated drinks, can accommodate typical variations in neck dimensions or surface finish. The steep upper face on the security lip causes the pendant bridges to break when the closure is removed.

Title: Milling flat end face on coil spring - involves use of split sleeve with bore grooves to contain coil spring and prevent deformation
IPC: B23Q3/06
Filed: 1979-06-27
Abstract: The system is used to mount and support a coil spring (1) during a machining of its extremity (8), effecting the complete immobilisation of at least the terminal coils at the extremity being treated. A continuous blocked support mechanism prevents any deflection or stressing of the spring during machining. A diametrically split and bored (4,5) block with bore grooves (6,7,10,11) locates the spring coils, the two halves (2,3) being clamped onto the spring. The top coil (8) may remain partly exposed for the milling of end faces perpendicular to the longitudinal spring axis. The immobilization of the spring may be completed by the use of a tool mandrel (9) which enters the spring core.

Title: Power economiser for internal combustion engine - has an freon evaporator in exhaust line with associated turbine and condenser
IPC: F02G5/04
Filed: 1979-06-27
Abstract: The engine (1)has a cooling circuit (2) operating in a closed loop with a circulating pump (3). The cooling liquid circulates through a radiator (5) cooled by a fan (6). The exhaust gases from the engine pass through an evaporator (8) which is part of the heat recovery circuit (9) containing an inert gas. The gas circulates through the turbine (10) connected to a generator (11). The fluid circulates through a condenser (15) and recycled under pressure by the pump (14). The valve (17) is positioned to by-pass the evaporator at start up, and the heater (15) is controlled by engine temperature.

Title: Improving image of scratched cinematograph film - has stock passing through batch of similar refractive index liquid before projection
IPC: G03B21/32
Filed: 1979-06-28
Abstract: The cinematograph film is unwound from the spool in the normal manner and passes over several guide rollers to form one or more loops. The lower of these rollers is submerged in a bath of liq., such as perchlorethylene or tetrahydronaphthalene, which has a refractive index similar to that of the film stock. The coated film then passes over additional rollers and through a gate, before the liq. has evaporated. The liq. fills all scratches and imperfections and renders them invisible when projected onto the screen. The film is then wound onto its final spool.

Title: Releasing pressure from reactors for vaporising fuels in dust form - by contacting hot gases with cooling shield surrounding reaction chamber
IPC: C10J3/78
Filed: 1979-09-28
Abstract: Appts. for releasing pressure from a reactor used for the vaporisation of fuels in the form of dust comprises a reaction chamber having a gap in its upper portion. A cooling shield surrounds the chamber and defines a cavity about the chamber with a surrounding layer of brickwork. Sockets are located in the lower region of the appts. and extend from the appts. exterior to the cavity. The cavity communicates with the reaction chamber through the gap. The sockets are used for releasing built-up pressure and for supplying inert gas to the reactor. Used for vaporisation of brown coal, pit coal, carbonaeous residues and organic materials at pressures between 5 and 50 bar for prodn. of gases contg. H2 and CO. The pressure is released safely without excessive usage of inert gas or additional cooling or spraying water or flying slag particles. The provision of a quench tube in the appts. for indirect cooling accelerates pressure release.

Title: Prepn. of apovincaminic acid ester(s) - by azeotropic dehydration of vincamic or epi-vincaminic acid ester(s); useful at hypotensives and vasodilators
Inventor: SZANTAY CSABA
IPC: C07D519/04
Filed: 1979-10-30
Abstract: Prepn. of (+)- or (2)-apovincamic acid esters of formula (I) is carried out by dehydrating a (+)- or (-)-vincamic acid ester of formula (II) or a (+)- or (-)-epivincamic acid ester of formula (III); (where R is 2-6C alkyl). Dehydration is effected in a water-immiscible solvent which forms an azeotropic mixt. with H2O, in the presence of a strong organic acid which as a dissociation constant of >=10-2, does not conform an azeotropic mixt. with H2O and has a low vapour pressure at the reaction temp. The H2O formed in the reaction is continuously removed by azeotropic distn. Cpds. (I) are useful as hypotensives and vasodilators. The process gives practically quantitative yields of high-purity (I) free of (II) or (III).

Title: Control circuit for variable speed output - compares actual shaft speed with pre-set value to operate pressure regulator for clutch piston
IPC: B62D11/18
Filed: 1979-11-03
Abstract: The speed of the output shaft of a variable speed output is controlled by a servo-control which takes a signal from its output shaft. The input shaft (1) drives the clutch (2) whose discs are operated by the piston (3) at a controlled pressure. The clutch output shaft (4) transmits the power through a torque converter to the output shaft (6). A proximity detector (7) monitors the actual speed of the transmitter (10), which is compared with a reference value A signal, related to the magnitude of the error, acts on the pressure regulator (9) which in turn controls the pressure on the piston (3) and the speed of the clutch output shaft (4).
