Patent FR-2231561-A1 (FR)
Title: Anchor with flukes shaped into a double ploughshare - flukes have a V-section which ends in V-shaped tip
IPC: B63B21/34
Filed: 1973-06-04
Abstract: The flukes are shaped into a double plough share which causes the fluke to drive further into the ground when the tension is increased on the anchor cable. The flukes are designed to swivel about the crown of the anchor so that should the cable foul the protruding fluke, this will collapse, and allow the cable to clear, without attempting to pull the anchor out of the ground. The flukes are also interchangeable with others, so that the correct fluke may be used according to the nature of the ground. The flukes have a V section which is deepest at the anchor crown, the V shaped ends of the flukes having sharpened edges.

Title: Sports suit sliding clasp fastener - extends along left of right side of the jacket to side of hood
IPC: A41D13/012
Filed: 1973-09-06
Abstract: The positioning device for sliding fasteners used in diving suits etc. enables the chin and adam's apple to be kept out of the fastener's way so the user has much more freedom of movement. It eliminates the bulkiness and stiffness, as well as the pulling on the fastener locking elements which otherwise decreases the sealing capabilities. The fastener extends over the left or right edge of the hood's opening in the cheekbone - ear area. By lowering the slide of the fastener the head may be taken out of the hood without having to open the jacket.

Patent FR-2302131-A1 (FR)
Title: Injection of gas into liquid - through small dia flexible tubes which move as gas is being injected
Inventor: DANEL FRANCOIS
IPC: C02F7/00
Filed: 1975-02-25
Abstract: Gas is fed into a main conduit which is partly or totally immersed in the liq. into which the gas is to be injected. That part of the conduit immersed in the liq. has many tubes of small inside dia., i.e. 2 mm and length >=20 times the dia. projecting from its surface into the liq. The gas passes up these tubes and is released at the tube ends as fine bubbles, the ends of the tubes moving in the liq. under the influence of the release of the bubbles and the currents in the liqs. These small injection tubes can be flexible or rigid and attached to the main conduit by a flexible connection. The main gas carrying pipe can be circular oblong or any other shape, or can be in the form of an annular conduit around walls or bottom of a vessel with the fine tubes projecting into the liq. Another alternative is to have the fine gas outlet tube surrounded by another tube up which a liq. is passed to cause the bubbles to detach from the gas tube. Used for injecting gases into liqs., e.g. in fermentation and for biological control of the oxygen requirement in polluted waters. Allows great uniformity of the injection of bubbles of the desired dia.

Title: Solar radiation energy collector - has liquid circulated between glass sheets and contg. suspension of carbon particles giving large absorption and contact area
IPC: F24J2/46
Filed: 1976-01-30
Abstract: The solar energy collector is formed of two sheets of glass spaced apart and sealed by a strip of elastic material. A fluid coloured black by a suspension of carbon particles circulates through the space thus formed.
