Title: Tank turret with automatic loading - has auxiliary magazine loading at any angle and supplied from main magazine
Inventor: DANIEL EDMOND
IPC: F41A9/04
Filed: 1979-10-08
Abstract: The tank turret has an automatic gun-loading feed, the gun recoiling in an axial diametral plane, while a magazine slews with the turret. The turret (1) is divided, by a partition (11) parallel to the plane in which the gun recoils, into a compartment (13) fothe crew (14) and one for the gun and the main magazine. The recoiling mass is fixed to a frame supporting an auxiliary magazine (36) and a transfer mechanism for the rounds (20) to the breech (5) from this magazine A further ram (25-29) slewing with the turret, transfers the rounds (20) from the main magazine to the auxiliary. The gun can be loaded from the auxiliary magazine at an angle of elevation, while transfer between magazines takes place at one particular angle.

Title: Biological removal of divalent iron from water - with aeration controlled in response to pH
Inventor: MOUCHET PIERRE
IPC: C02F3/00
Filed: 1979-11-21
Abstract: Removal of divalent Fe from underground or surface water is effected by partially oxygenating the water and passing it through a bed of specific autotrophic bacteria supported on a filter medium, with the improvement that the amt. of O2 dissolved in the water is controlled in inverse proportion to the pH of the water. The improvement prevents physicochemial pptn. of basic ferric salts, which is less efficient than biological oxidn. The maximum dissolved O2 content should be 7 mg/l. at pH 7, 2 mg./l at pH 7.1, 0.5 mg/l. at pH 7.2, and 0.1 mg/l. at pH 7.3 or higher. These O2 levels can be achieved by percolating the water through the biological filter bed, aerating the effluent water to satn. point, and recycling the O2-satd. water for mixing with the incoming water in an amt. controlled in response to the pH of the incoming water.

Patent FR-2477586-A1 (FR)
Title: Shuttleless loom with Cardan circle transmission system - with energy-accumulating masses, to increase loom speed (BR 8.9.81)
Inventor: JUILLARD YVES
IPC: D03D47/27
Filed: 1980-03-07
Abstract: On a shuttleless loom, where weft insertion is effected by weft-carriers such as needles or lances, which pass from a point beyond the selvedge to the centre of the warp shed, the weft insertion is controlled by a mechanical transmission system known as a "Cardan Circle". This known transmission system is improved by the introduction of an energy accumulating or restoring mass on each turning arm driving the weft-carrier. The mass offers a method of complete control of weft transfer, and absorbs irregularities in machine movement. The improvement of the invention to the "Cardan Circle" transmission system allows increased running speeds of 250% compared with existing looms.

Title: Electrical fitting accessory inserted into table lamp base - uses insulating cylinder with tapered grips end flange lamp holder mounting screw push fitted into hole in base
Inventor: CALVAIRAC JEAN-JACQUES
IPC: F21V21/06
Filed: 1981-01-07
Abstract: The components are fitted into the base of a standard lamp using an accessory which is push-fitted into a vertical passage through the length of the lamp base. The electric supply cord enters at the side in the lower part of the lamp base when passes through the hollow centre of the accessory to the bulb holder.

Title: Microphone for optical fibre communications link - uses membrane with light absorbing surface to affect optical path in totally reflective prism
Inventor: PARQUIER GUY LE
IPC: H04R23/00
Filed: 1981-09-15
Abstract: A prism (2) with total internal reflection has a flexible membrane (5) fitted into a housing (7) in its large face. The membrane has a hole (5a) to permit balancing of the static pressure on both faces. The prism is mounted in a support (24) and has a protective grid (25) covered by the mouthpiece (22) screwed onto the handset (21). The handset has two housings (27a,b) in which collimating lenses (3a,b) are fitted with their focal points at the ends of optical fibres (4a,b) and adjacent to the small faces of the prism. One optical fibre (4a) permits coupling of the prism to an external light source while the other fibre is coupled to a photodetector. Movement of the membrane which has a light absorbing surface facing the prism causes part of the light energy to be subtracted from the transmitted energy.
Patent FR-2492881-A1 (FR)
Title: Clamp for tubes or drill rods - where distance between pair of coaxial clamping jacks can be altered to suit drill rods of varying dia.
Inventor: CHRISTAMANN WALTER
IPC: E21B19/16
Filed: 1981-09-30
Abstract: Tubes or rods which will be rotated are joined together coaxially by two clamping jaws. Each jaw is located on the piston rod of a jack; and the piston rods are coaxial. Each jack has a pair of lugs located in a recess in two plates which are bolted on a frame. The recesses are not in the middle of the plates, so that when the plates are rotated through 180 deg. the distance between the coaxial jacks is altered. The result is that one clamp can be used for tubes with a wide range of dia. In the past, several clamps with difference sizes were needed to accommodate tubes or drill rods with different dias. The invention provides a clamp suitable for many sizes of tube or rod.
