Title: Polygonal bell tent frame - has inflatable radial ribs converging on apex for flat ends to be superimposed between plates secured by through bolts
Inventor: JANNY LOUIS-MICHEL
IPC: E04H15/20
Filed: 1980-05-28
Abstract: The demountable building takes the form of a polygonal bell tent with support by radial inflatable tubular ribs (1). The ribs converge on the pointed overhead apex of the tent, their ends (5) being flattened (4) to be superimposed in a bolted (10) joint. The major faces of the flattened ends are vertical, the ribs being divided into two converging groups (6,7) of which the respective ends alternate in the joint. Welding may be used to seal the ends, and the joint may use bolts with nuts (12) to connect rectangular metal cover plates (8,9). The bolts may pass through aligned holes (11) in the plates and rib ends, and the plate length (L) may exceed that of individual ends. The latter feature allows each effective rib end (13) to be sited within the boundary of the cover plates.

Title: Rotary single piston IC engine - has eccentrically rotating piston with two parallel sliding blades moved past end openings
IPC: F01C1/344
Filed: 1980-06-24
Abstract: The rotary piston internal combustion engine with a single piston, has a cylindrical piston incorporating two slots for two sliding blades. Each blade is held in contact with the inside surface of the cylindrical casing by springs behind it, at the bottom of the slot. As the piston is rotated eccentrically inside this chamber, the two blades form a chamber between them which is moved past the open mouths of two inlet and outlet ports through an end plate of the cylindrical casing and shaped as parts of a crescent. The piston carries a gear pinion which roates inside a toothed ring, controlling its eccentric rotation.

Title: Bolt assemblies for locating sacrificial anodes on tank walls - esp. to provide corrosion protection in tanker ships carrying petroleum, where sea water forms the electrolyte
IPC: F16B3/06
Filed: 1980-07-04
Abstract: Each assembly consists of a conical stud ending in a screw thread and entering the conical bore of a flanged bush with a shoulder on its external dia. The minor dia. of the bush is inserted in a hole in a wall requiring protection against corrosion by a scrifical anode, whereas the major dia. of the bush is inserted in a hole in the anode. The bush also has a longitudinal slot which is pref. oblique w.r.t the axis of the bush. When a nut is screwed onto the stud, the anode is clamped against the wall to be protected by the flange on the bush. The bolt assemblies are simple and rapid to use, and replace lengthy welding operations, which can be dangerous when undertaken in oil tanker ships.

Title: Heat transfer appts. using heat pump - where light hydrocarbon dissolved in heavier hydrocarbon is used to supply heat from source to dissipator at higher temp.
Inventor: BOUVIN JACQUES
IPC: C09K5/04
Filed: 1980-07-15
Abstract: Heat is transferred from a source at temp. (T1) to a dissipator which is at a higher temp. (T2). The process includes heating a soln. in a distn. column. The soln. consists of a working fluid (I) contg. at least one hydrocarbon with n C atoms/mol., which is dissolved in a liq. absorbent (II) contg. at least one hydrocarbon with m C atoms/mol.; m - n is 1 to 20, and pref. 3 to 11. The soln. is fed into a distn. column to obtain a vapour (VI) rich in cpd. (I) and at a temp. (T3) above T2. The vapour (VI) is fed through a condenser, so heat in the vapour is transferred to the dissipator and to condense at least part of vapour (VI). In an example, cpd. (I) is n-butane dissolved in n-octane. The working fluid and its solvent are inexpensive and of low toxicity, and can be used up to their decompsn. temps. of e.g. 350 deg.C with high yields.

Patent FR-2465229-A1 (FR)
Inventor: BERNEY JEAN-CLAUDE
IPC: H02P8/02
Filed: 1980-09-02
Abstract: An electronic timepiece comprises a stepping motor driven by alternating square wave pulses, and a detector circuit for detecting the non-rotation condition of the rotor. The detector circuit is responsive to motor load current and looks for the presence of points A, B or C in the load current waveform curve 3 Fig. 1 which indicates normal rotatable condition. If the rotor has missed a step or the load is excessive such that these points are not detected, the load current being as waveforms curves 1, 2 Fig. 1, the detector circuit output is used to progressively adjust drive pulse duration accordingly as in Fig. 7 arrangement, or to make up for lost steps as in Fig. 6 arrangement. The detector circuit comprises an amplifier 24 including MOS transistors 1, 2 (eg as in Fig. 2) and a capacitor 3. Voltage applied to the amplifier is proportional to and has the same waveform as the motor drive current.

Title: AC power supply for rotating anode x=ray tube - has series current transformer driving logic circuit to switch tube on synchronous speed attained by synchronous motor
Inventor: SEIFERT GERD
IPC: H05G1/26
Filed: 1981-06-18
Abstract: A three-phase supply is rectified and used to power an oscillator circuit whose output drives the windings of an asynchronous motor turning the anode of an X ray tube. A current transformer detects the current flowing through the motor windings and is connected to a circuit which starts the radiography after an increase in amplitude of the motor current when the motor has reached its operating speed. The current transformer output is rectified and filtered then differentiated ans passed through a pulse shaper which drives a bistable multivibrator. An inhibit signal is applied to an AND gate together with the output of the multivibrator to control the X ray tube. The inhibit signal resets the multivibrator which is set by a pulse produced by the shaper circuit when the output of the current transformer is changing. The oscillator consists of controlled rectifiers shunted by freewheel diodes and capacitatively connected to the motor windings.

Title: Automatic focus correcting system for submarine periscope - uses photocell to discriminate between images in front or behind its plane to control focus lens displacement motor
Inventor: PREVOST MARC
IPC: G02B23/10
Filed: 1981-09-11
Abstract: The observation head of a periscope is connected by a long tube to a box containing the observation elements. The beam from an area of the field of view is reflected by a prism to pass to a semi transparent mirror where it is split into two paths one of which passes to an eyepiece. The other path is directed to a photographic plate. Automatic focussing correction system comprises a luminous source whose radiation is outside the luminius spectre of the observed field. The beam passes through an objective lens to pass to the semi transparent mirror where it is separated from the light from the field of view. A photocell discriminates between images in front of and behind it and a servo circuit determines the exact image plane from a sight near the source. The output controls a motor to displace the objective lens to maintain the two signals equal in amplitude and thus correctly focus the periscope.
