Patent number: 3980324Abstract: This coupling comprises a rotary cylindrical portion which is recessed and an outlet opening whose lower edge is placed level with the lowest point of a surface which is inclined relative to the rotation axis, whereby the said surface is placed adjacent to the axis and the side opposite to the said opening.This coupling is more particularly intended to be used on the inlets and outlets of pneumatic automatic control modules.Type: GrantFiled: March 10, 1975Date of Patent: September 14, 1976Assignee: La Telemecanique ElectriqueInventors: Daniel Bouteille, Michel Nicolas
-
Patent number: 3980978Abstract: The present invention relates to a small electromagnetic relay comprising three independent sub-assemblies serving to fulfill respectively the function of motor, contact and connecting base and which can be assembled together.The contact sub-assembly is formed by an arcing box having recesses serving to receive the contact supports held in place between the base and the motor.The relay according to the present invention is applicable to automation and control circuits.Type: GrantFiled: May 13, 1975Date of Patent: September 14, 1976Assignee: La Telemecanique ElectriqueInventor: Guy Lacan
-
Patent number: 3978738Abstract: Manipulator operating switches with the aid of a lever moving around a knuckle.The lever is associated with two rectangular devices each of which being returned to the inoperative position by two levers each one associated with a spring.Advantageous arrangement in manipulators controlling lifting gear.Type: GrantFiled: December 24, 1974Date of Patent: September 7, 1976Assignee: La Telemecanique ElectriqueInventor: Michel Naulin
-
Patent number: 3970978Abstract: The object of the present invention is a direct current-operated electromagnet.The branch of the armature which penetrates the coil body cooperates with a fixed core branch in three distinct successive modes due to the action of different air gaps.It can advantageously be used on relays for automatic equipment or on small contactors whose number of contacts is variable and/or subject to time lags.Type: GrantFiled: January 3, 1975Date of Patent: July 20, 1976Assignee: La Telemecanique ElectriqueInventor: Michel Langree
-
Patent number: 3970356Abstract: The present invention relates to a socket for a busbar.A socket body is formed by folding a copper-aluminium portion in such a way as to form a sheath whose inside is formed by the copper-plated surface which serves for the fixing of the socket to an aluminium busbar by spot welding.The invention can advantageously be applied to power distribution busbars protected by sheaths.Type: GrantFiled: March 17, 1975Date of Patent: July 20, 1976Assignee: La Telemecanique ElectriqueInventor: Jean Joly

Patent number: 3964006Abstract: The invention relates to electrical commutation apparatus of the kind having a fixed core, a coil, a movable armature constituting a motor, a frame including shaped engaging means placed perpendicularly to the movement of the armature to support a number of housings each containing fixed and movable elements of a contact, and a shaped body member for control of said contacts. The object is to provide improvements in dimensions, avoidance of vulnerability to dirt, and adequate rigidity without undue bulk. These are obtained in that the frame and the control member are each constituted by at least one portion of a prismatic body cut longitudinally and in that the shaped body comprises at least the engaging means for the housings and the surfaces for guiding movements of the armature.Type: GrantFiled: December 26, 1974Date of Patent: June 15, 1976Assignee: La Telemecanique ElectriqueInventor: Guy Lacan
-
Patent number: 3951007Abstract: A set of removable combination cams has an assembly of identical rotary components mounted on a common rotary shaft and carrying removable cams for operation of switches. The rotary components are coupled together in such a manner that they can move relatively perpendicular to the axis of rotation, so that at least a portion of the periphery of one of the components is uncovered to allow fitting of the cam elements. Thus, the cam elements can be fitted without dismantling the assembly, and without changing the relative angular positioning of the rotary components, and without utilising resilient deformation of the materials employed, whilst retaining small axial dimensions for the assembly.Type: GrantFiled: December 26, 1974Date of Patent: April 20, 1976Assignee: La Telemecanique ElectriqueInventor: Michel Naulin

Patent number: 3941445Abstract: The invention relates to an arrangement for connecting electrical installations or equipment to chassis containing electrical apparatus. Connectors, identical to those used within the chassis, are located on the exterior side walls of the chassis, and cooperate with a series of detachable plugs which are slidably guided into aligned cooperation with the connectors by means of ribs on the side walls, and latchingly engage with the side walls to retain them electrically interconnected with the connectors. The height of each plug is a multiple of the pitch between the rows of connector pins of the connectors, thus enabling several plugs to be plugged, side-by-side, to the same connector.Type: GrantFiled: April 8, 1974Date of Patent: March 2, 1976Assignee: La Telemecanique ElectriqueInventor: Guy Lacan

Patent number: 3942144Abstract: The invention relates to a contact holder for an electromagnetic contactor or relay, the contact holder being slidably displaceable within a contactor housing by the contactor armature to guide the armature and change the contact state between movable contacts carried by the contact holder and fixed contacts carried by the housing. The contact holder comprises first and second parts formed from insulating material which are joined together, the first part being connected to the armature and provided with seatings on which movable bridge contacts are located, and are held in place by the second part. Elongate openings are formed in the first part between adjustment seatings, and isolating or anti-arcing partitions integral with the housing extend through the openings.Type: GrantFiled: February 13, 1974Date of Patent: March 2, 1976Assignee: La Telemecanique ElectriqueInventor: Maurice Contal
