Title: Support block holding cable to extruded metal channel - has two shaped slots allowing insertion into channel and locking action using quarter turn
Inventor: GOUEL PATRICK
IPC: F16L3/24
Filed: 1981-11-27
Abstract: The block (10) which may be fastened to a C-section metal channel is made of relatively hard plastic material which has a restricted limited degree of elasticity. The block has two slots (11,12) cut into two opposite faces, leaving a cylindrical portion (13) uncut in the middle of the block. The block is inserted between the free edges of the C-section metal channel and then rotated by a quarter turn. This enables the faces (111,112, 121,122) to slide over the surfaces of the channel, holding it in place. The part of the block which projects (102) from the metal channel is slightly shorter in length than the width of the metal channel, and has a slot cut through to receive a strap of cable. Edges (101) of the block are chamfered to facilitate insertion, and the corners are rounded to allow the block to rotate in one direction only.

Title: Digestion of liq. waste producing methane and dried sludge - employs steam from drying sludge to heat liq. in digester
Inventor: MARECAUX PAUL
IPC: C02F11/12
Filed: 1982-02-25
Abstract: The digestion temp. is kept above ambient by input of heat from an external source. Sludge from the digester is partially dehydrated e.g. by filter press, and then heated in a dryer which evaporates water, producing steam. The steam so produced is used to provide the heat input required in the digester vessel. The steam can be directly injected into the liq. in the digester or in a recycling circuit associated with the digester. Alternatively, the steam can be passed through an indirect heat exchanger to transfer heat to processed liq. either inside the digester vessel or in an external recycling circuit. This is an anaerobic digestion process and installation in which liq. organic waste is fermented to produce a fuel gas and a residual sludge which is dried for use as agricultural fertiliser.

Patent FR-2524108-A1 (FR)
Inventor: DEGENER GERD-RAINER
IPC: F16K37/00
Filed: 1983-03-18
Abstract: A transversely divided operating rod, the parts of which are forced apart against a stop by spring force, serves for actuating the position monitoring of the valve control element. The one part is connected to the valve control element for driving it, the other part carries at the end a soft magnetic end face for interaction with a sensing plane of an inductive proximity switch arranged transversely to the longitudinal direction of the operating rod and parallel to the said end face. When the valve is operated the soft magnetic end face encounters the sensing plane of the proximity switch after just a fraction of the stroke of the valve control element. Thereafter the parts of the operating rod slide together, thereby permitting the completion of the stroke of the valve control piston.

Title: Device for armouring a door incorporating a multi-lock linkage mechanism
IPC: E06B5/11
Filed: 1983-07-08
Abstract: The invention relates to a device for armouring a door, incorporating a multi-lock linkage mechanism and hinge plate reinforcements. The device consists of a multiplicity of modular elements which are joined together and to the edges of the door through the use of angle bracket fasteners. Each element 10 slides between a section 19 and a section 20 which are fixed respectively to the top and the bottom of the door. No cutting of the linkages or of the armouring device is required for matching it to the width or the height of the door. The most beneficial application is the protection of apartment (flat) doors. Indeed, the fitting or removal of the armouring device in no way damages the internal face of the door leaf. What is more, the strength obtained by screwing exclusively in the rebate gives the armouring device a strength which is incomparably better than conventional armourings consisting of applying a metal sheet screwed onto the front panel.
