Patent FR-2266336-A1 (FR)
Title: Tool for extraction of contact pins - disengages sprung holding rings and withdraws pin
IPC: H01R13/426
Filed: 1974-03-25
Abstract: The tool is designed to remove electrical contact pins (10) which are held in an insulating block by sprung grips (31) or collars set in the insulator (20). The hand held tool operating from the rear of the insulator, is in the form of an outer metal or plastic tube (40) shaped and slotted at its gripping end such that it may be compressed. Inserting the tool pushes back the sprung grips (31) and grips the rear section (15) of the pin. The pin is ejected from the tool by a sprung central rod inside the tube. The gripping end of the tube may be serrated on its inner surface to engage with any further shoulders on the pin.

Title: Gallstone extracting and locating device - has wire spiral at end of rod expanded and passed around stone
IPC: A61B17/22
Filed: 1974-06-20
Abstract: The extractor comprises an elongate flexible rod with a gall-stone gripper at one end and an actuating handle for the gripper at the other end.

Title: Pres-stressed glass alarm disc - in which fragmentation of the glass breaks a conductor and activates an alarm circuit
IPC: G08B13/04
Filed: 1975-01-30
Abstract: In a glass alarm disc of the known type in which can electrical conductor connected to a circuit is mounted on a prestressed glass disc and is broken when the disc is damaged so that an alarm or protective device is operated, the improvement whereby at least a part of the electrical conductor is situated in a corner region of the glass disc, the edges or sides of the visible surface of this region being firmly attached to the frame enclosing the glass disc or to some other object. Ensures that on fracture of the disc - which since it is pre-stressed breaks into a large number of small pieces - the electrical conductor is broken, which in earlier devices was not always the case when the disc was mounted in a frame. The principle can also be applied in modified form for the case where the pre-stressed glass disc is laminated to one or more additional glass discs.

Title: Turret power tool for tightening preloaded bolts - has grips to rotate bolt head and uses short stroke jack to compensate for bolt weight
Inventor: BOUDET GEORGES
IPC: B23P19/06
Filed: 1976-04-30
Abstract: The turret type power tool is for tightening large dia. bolts esp. of the pre-loaded variety holding down nuclear pressure vessel covers. the tool is equipped to grip and rotate the bolt head, to apply a torque and an axial force to the bolt, to compensate for bolt weight and to effect guidage with axial displacement. The bolt weight compensation mechanism may comprise one or more jacks acting parallel to the axis of the bolt tightening mechanism. the force applied by the jacks is adjustable and sufficient to displace both the bolt tightening and gripping mechanism, serving to promote axial displacement. a single small short-stroke jack may be mounted between the spindles of the bolt tightening and gripping mechanisms. the advance of the turret is thus equated to bolt pitch.

Title: Converting bird droppings into dry powder fertiliser - by mixing with a powdered organic drying agent to extract moisture without affecting the chemical and bacterial content
IPC: C05F3/00
Filed: 1976-07-09
Abstract: Dry organic fertiliser compsns. are made by mixing guano or droppings from wild or domestic birds in a mixer-grinder with a suitable amt. of a dry powdered organic material which completely absorbs the moisture from the base material, and continuing the mixing until a homogeneous dry powder is obtd. Pref. the bird droppings are fed from a closed container into a screw kneader together with the powdered organic drying agent, and the dry powder prod. from the mixer is fed directly into an extruder for the prodn. of pellets. Suitable drying agent is dried pulp and pips of grapes, from which the oil has previously been extracted. The fertiliser obtd. contains all the original useful chemical components and microorganisms (bacteria) contained in the bird droppings, so that the prod. has maximum effect when applied to the soil. The process is economical in the use of energy and avoids treating the droppings e.g. with lime, as in previous practice.
