Title: Centrifuged blood samples - transferred as sepd constituents without remov-ing sample container from centrifuge
IPC: A61J1/00
Filed: 1972-08-10
Abstract: Blood is centrifuged in a collapsible pocket fitted inside a rigid carrier frame so that the blood separates into constituent layers of red blood corpuscles and serum, ready to be drawn off separately into receivers for each constituent. The inside of the carrier frame is lined with an inflatable bag which can be inflated to compress the pocket as the bag distends, thus progressively driving out fluid, i.e. the separate constituent layers, for collection. This collection can be effected without removing the carrier frame from the centrifuge so that there is no danger of disturbing the boundary between the layers. System is hygienic employing no seals or mechanical parts.
Patent FR-2227096-A1 (FR)
Title: Underwater percussion tool - utilising the water pressure as the percussion force
IPC: F01B11/04
Filed: 1973-04-26
Abstract: Percussion tool for underwater working, e.g. for breaking up rocks, pile driving etc., of the known type has working punch element and a hammer element but in which the hammer consists of a hollow cylinder in which the working punch or chisel is at least partially lodged and means are provided for displacing >=1 of these elements relatively to the other, and for creating a vacuum in a cavity arranged between these elements in such a way that after their release, the energy accumulated by >=1 element as a result of the pressure of the ambient medium is transmitted at least partly to the other element. The tool is less damaging to the environment than the use of explosive charges and has the great advantage that the efficiency increases with depth of use. If the cavity is initially filled with water, this can be driven out by detonating the product of a reaction between water and a suitable matl. e.g. potassium peroxide/lithium hydride, by means of the electrical element.

Title: Overhead cable anchor - permits branched conductor to be unbolted for maintenance
IPC: H02G7/05
Filed: 1974-06-07
Abstract: This cable anchor for overhead power lines has a main body in line with the conductor and the means of attachment to an in-line insulator (E).

Title: Analogue to digital and digital to analogue converter - particularly for digital communication systems performs signal compression and expansion
IPC: H03M3/02
Filed: 1975-09-16
