Patent CA-1051962-A (CA)
Inventor: CHRIST ALFRED
IPC: F16C33/06
Filed: 1976-12-01
Granted: 1979-04-03
Abstract: ABSTRACT      The disclosure concerns hydrostatic apparatus for supporting a mobile part which moves relatively to a found-ation and which comprises a bearing shoe having a bearing face containing a pressure pocket, and a hydraulic servo-motor which exerts on the shoe a force urging it toward the mobile part.  A support element connected with the shoe and the foundation positively holds the shoe against movement in at least one direction along its supporting axis, and its restraint is so correlated with the pressure forces acting on the shoe that the latter is rendered non-displaceable.          Depending upon the relative magnitudes of the forces developed by the servomotor and by the pressure acting on the bearing face, the support element may normally be unloaded, loaded in tension or loaded in compression.  In the first case, the support element prevents movement of the shoe in opposite directions along the support axis, whereas in the second and third cases it may permit movement of the shoe toward and away from the foundation, respectively.

Abstract: ABSTRACT OF THE DISCLOSURE         The invention provides a pyrotechnic device comprising a casing containing an electrically-operable ignition device for igniting a charge, the ignition device comprising a base and an electric igniter head electrically connected to two spaced and mutually insulated terminals in the base.  One terminal is disposed centrally within the base and the other terminal is located, at least in part, on the periphery of the base.         The base is fitted within an opening in an electrically-conductive wall of the casing, the other terminal making electrical contact with this wall.  Means are provided to prevent the ignition device from being ejected from the casing under the shock loading resulting from ignition of said charge.

Title: Optical device for the injection of radiation energy into an optical fibre and for coupling a plurality of fibres
Inventor: HUNZINGER JEAN-JACQUES
IPC: G02B6/26
Filed: 1976-12-07
Granted: 1980-04-08
Abstract: ABSTRACT:               The optical device in accordance with the in invention mainly comprises two very thick plane-convex lenses with a common axis, the convex surfaces facing each other.               The radiation source and the input face of a fibre are each disposed on one of these surfaces in the vicinity of the axis.               The main feature of the device resides in the considerable thickness of the lenses relative to the radii of curvature of the dioptric faces. As a result, aberrations, in particular spherical aberra-tions, are reduced whilst the dimensions of the device are such as to enable easy construction and handling.

Abstract: APPARATUS FOR MIXING A VAPORIZED LIQUID        FUEL WITH AIR          ABSTRACT OF THE DISCLOSURE           A mixing apparatus for mixing a vaporized liquid fuel with air to develop a combustible air/fuel mixture is described.  A finned swirl inducing member having a centrally located aperture is positioned downstream from a metering venturi and upstream from a plain tube mixing section.  The centrally positioned aperture is sized and spaced to allow passage of a stream of vaporized liquid fuel delivered to the low pressure zone formed by a metering venturi.  The fin members of the swirler are operative to cause a swirl of the air stream passing through the metering venturi.  The swirling air stream prevents any direct contact between the vapor stream and the relatively cool side walls of the mixing section while causing mixing action between the interiorly constrained vaporized liquid fuel stream and the inner portions of the air swirl.

Abstract: INTEGRAL COLOR FILTER FOR SOLID-STATE IMAGING DEVICE    Abstract of the Disclosure A method for making a color imaging device which comprises means for sensing radiation comprising a planar array of charge-handling semiconductive photosensors, at least some of the photosensors having a radiation-sensing area with at least one dimension less than about 100 microme-ters and, superimposed thereon, filter means for controlling access of radiation to the sensing means.  The filter means comprises a transparent, polymeric dye-receiving layer for receiving heat-transferable dyes and further comprises a plurality of radiation-intercepting means defining a planar array of filter elements lying in the receiving layer in microregistration with the sensing areas of the photosen-sors.  The filter area of each intercepting means contains at least one heat-transferable dye transferred to the dye-receiving layer by heating and diffusion.  The heat-transferable dye absorbs radiation in at least one portion of the spec-trum and transmits radiation in at least one other portion of the spectrum.  The color imaging device comprises an interlaid pattern having at least two sets of dye-intercepting means, the first set having a radiation absorption and transmission characteristic different from that of the second set.  The heat-transferable dye is diffused into the dye-receiving layer at an elevated temperature through window areas in a photoresist layer.

Abstract: Docket #6900 Abstract of the Disclosure A snap acting switch has a switch blade which is pivotally mounted for movement between two positions and is normally held in one position by an actuator spring.          An actuator lever is pivotally mounted on the switch housing and has an external lever arm portion and an inner lever arm portion within the housing which is engageable with the actuator spring to move the spring laterally past the longitudinal axis of the switch blade in response to movement of the external actuator lever arm portion, to thereby cause snap acting movement of the switch blade from its normal position to a second position.  Release of pressure on the external lever arm portion permits the actuator spring to cause snap acting movement of the switch blade back to its normal position.

The compounds of the invention of the general formula have valuable pharmacological properties.  They exhibit central depressive, antidopaminergic, antiociceptive and anticonvulsive actions, and thus have a certain similarity to neuroleptics such, for example, as chlorpromazine and haloperidol.  However, the compounds of the invention differ from the classical neuroleptics in having different kind of influence on receptor-dependent, monoaminergic feedback mechanisms (decrease or extrapyramidal side effects).
