Title: Three dimensional imaging device
Inventor: RIOUX MARC
IPC: G01B11/24
Filed: 1989-08-24
Granted: 1993-06-15
Abstract: Abstract of the Disclosure A three dimensional imaging device has a converging lens system defining an optical axis, known as the z direction.  The imaging device also includes a position sensitive detector that has a series of pixels extending in at least a selected one of two mutually perpendicular X and Y directions both perpendicular to the Z direction.  The lens system will simultaneously image a plurality of distributed points on a target surface onto the detector to generate first data on the coordinate of each point on the target surface in the X and/or Y direction.  Also included in the system is a mask having a pair of apertures spaced apart from each other in the selected direction and respectively aligned with portions of the lens system for imaging discrete dots on the detector. The spacing between the dots generates second data on the coordinate of each point on the target surface in the Z direction.  The device is modified in such a way as to cause a point on the target surface at a reference plane that would normally appear as a single focussed dot on the detector now to appear as a pair of spaced, substantially fully focussed dots. This modification takes the form of modifying the lens system such that a pair of spherical lens portions are rendered aspherical with respect to each other while each remains spherical with respect to itself.  Another component of the system scans the pixels to extract data for all points on the target surface.

Abstract: METHOD AND APPARATUS FOR SENSING DIRECT CURRENT OF ONE POLARITY IN A CONDUCTOR AND ELECTRONICALLY   COMMUTATED MOTOR CONTROL RESPONSIVE TO SENSED                 MOTOR CURRENT                  ABSTRACT OF THE DISCLOSURE           Apparatus and method for generating a sensing signal which is a function of a direct current flowing in a particular direction in a conductor.  A core inductively coupled to the conductor is subject to negative magnetic saturation after a period of time as a result of a magnetic field generated by the direct current in the conductor.  The aforesaid period of time is a function of the magnitude of the magnetic field generated by the direct current flowing in the conductor.  An output winding around the core produces an output signal which is a function of the direct current in the conductor when the core is not saturated but which is not a function of the direct current in the conductor after the aforesaid period of time.  A reset winding is periodically driven by a pulse to reset the magnetic orientation of the core to positive magnetic saturation before the aforesaid period of time elapses.  As a result, the output signal produced between periodic resets has a magnitude which is a function of the direct current in the conductor and comprises the sensing signal.  A motor voltage is applied to one or more winding stages of a motor in accordance with a regulating signal which is a function of the sensing signal.  The winding stages are commutated in a preselected sequence to rotate a rotatable assembly of the motor.

A generally upwardly extending solid front wall is formed at an upstream edge of the plate and an upper end of the front wall extends above the surface of the body of water. A generally upwardly extending rear wall is formed at a downstream edge of the bottom plate and has a plurality of regularly spaced orifices formed therein. A generally upwardly extending intermediate wall is formed between the front wall and the rear wall and also includes orifices, the front wall and the intermediate wall forming therebetween an energy dissipation basin. The front wall extends above the surface of the body of water so as to prevent the passage of a sea swell above the bottom plate as long as the amplitude of the swell is average. The water between the bottom plate and the bottom surface of the body of water behaves like an inert obstacle whereby at least a portion of an incident sea swell is reflected and any swell wave transmitted downstream is of reduced amplitude.

The recorded value for the current (104) and the recorded value for the voltage (102) together with the information in respect of the passage through zero of the supply voltage (100) are connected directly via conversion circuits (25, 26) to a data processing unit (112). This (112) is so arranged that in relation to the value (102,104) of the actual direct current and direct current voltage in the dust separator and with reference to the passages through zero (100) it will on the one hand calculate a specific time interval for the switching in and/or switching out of the rectifier (8) from the power supply and on the other hand generate switching-in and switching-out pulses (112a, 112b). These switching-in and switching-out pulses are fed directly, via adapter circuits, from the data processing unit.

Apparatus for making filaments; cellulose - xanthates, processes for making filaments from.- In the manufacture of viscose silk, transference - of the material from the original collecting spools is avoided by employing a foraminated spool made from a material which resists the action of the desulphurizing-mechanism, and by subjecting the silk while on this spool to the several baths required for the purpose of removing acid, bleaching, desulphurizing, soaping, &c., the baths being caused to flow through the material. Suitable materials for the spools are stainless steel and ceramic materials. As a modification, the silk is partly treated on the original foraminated spool and then transferred to a foraminated twisting spool, the treatment being completed while the silk is on the second spool. By forcing the baths through the silk the duration of the treatment is appreciably shortened. Specification 250,303 is referred to. The Specification as open to inspection under Sect. 91 (3) (a) describes an arrangement, for use in carrying out the treatment, comprising a spool a of stainless steel covered with a layer b of felt, on which a mass c of silk is spun. The treatments are carried out in a vat d provided with pipe connections f to an exhaust pump, the pipes leading from seatings i; the spools are piled up on the seatings, packing pieces g being placed between their ends, and the exposed end of the uppermost spool being closed by a stopper h. The Specification refers also to the creation of a vacuum within the spool for the purpose of causing the passage of the liquid therethrough. This subject-matter does not appear in the Specification as accepted.
