Patent EP-0042946-A2 (EP)
Inventor: DICKSON LEROY DAVID
IPC: G02B26/10
Filed: 1981-05-12
Abstract: The holographic scanner includes a rotating glass disk (20) having an annular track of sectorial holographic diffraction gratings or holofacets (22) for deflecting an impinging laser (24) beam along arcuate scan lines. The beam which sweeps along these scan lines is redirected by beam folding mirrors (30), to create specific scan patterns focused in predetermined regions (36,38) adjacent a scanner window (32). Similar or dissimilar scan patterns can be generated depending upon the characteristics of the holofacets (22) and the placement of the beam folding mirrors (30). The scan patterns can be focused at different distances from the scanner window (32) to increase the size of the "gate" through which a label must pass in order to be successfully scanned. The returning light is focused by a lens (40) onto a photodetector (42) which generates an electrical signal proportional to the reflected radiation amplitude.

IPC: H02P5/68
Filed: 1981-10-20
Abstract: In apparatus which uses a plurality of stepper motors for the actuation of various moving members therein, e.g., impact printer apparatus, an improvement is provided wherein at least one pair of stepper motors (14, 15) which operate during mutually exclusive periods share common driver means (13) which are switchable to be connected to the active stepper motor and disconnected from the dormant one. When thus connected to the active stepper motor, the driver means operate in the conventional manner to couple the windings of the active stepper motor to the particular current supply associated with that active motor in a predetermined sequence so that each winding of the active motor is energized during portions of the sequence and deenergized during other portions. The apparatus further includes switching means (16) for selectively connecting and disconnecting the drive means to the first and second stepper motors in accordance with the requirements of the apparatus driven by said stepper motors.

Abstract: The invention relates to a method for operating a high velocity burner in which fuel and air are substantially burnt out under excess pressure in a combustion chamber and the combustion products (flue gases) emerge into the space to be heated at high velocity from a nozzle-like aperture which is small in comparison with the end face of the combustion chamber. An improved turbulent and circulatory effect in the stove chamber connected to the burner is achieved when the ratio P1/P2 of the combustion chamber pressure P1 to the pressure in the space behind the combustion chamber P2 is greater than 1.2. A device for carrying out the method is also proposed. <IMAGE>

Abstract: In a CMOS integrated circuit certain high-impedance nodes are particularly susceptible to noise signals from the power supply. The power supply noise rejection is improved by using transistors 72, 74 of one type only, which are formed in tubs, such as N-channel transistors formed in P-type tubs in an N-type substrate, for connection to the critical high-impedance nodes 76. The tubs of these transistors are preferably connected (via 70) to an on-chip regulated power supply 66, 68. Noise rejection is further improved by grounded tubs underlying any conductive runners 80, 82 and capacitors 84 connected to the critical nodes 76.

The primary scanner provides a main optical scanning beam and an auxiliary optical scanning beam (20C) traversing substantially the same optical path. The error sensor includes a graticule mask (22) having a substantially uniform optical density along the desired scan path and a graded optical density transverse to the desired scan path of the auxiliary scanning beam.

Abstract: The supply of hydraulic fluid to actuators (BR) of friction devices for engaging the various ratios in an automatic transmission from a high pressure source (42) is controlled by relay valves (RV) which maintain the pressure in the actuators at a multiple of a control pressure. The release of an outgoing friction device (BR4) and engagement of an incoming device (BR3) are controlled by a shift timing valve (STV3, 4) and shift timing trimmer valve (TV3, 4) associated with each friction device. During an upshift, the outgoing trimmer valve (TV4) is allowed to partially release its pressure and thereafter to continue to lose pressure at a reduced rate until the pressure in the incoming brake (BR3) is sufficient (i.e., when the brake BR3 can withstand driving reaction) to operate the shift timing valve ST4 to empty the trimmer (TV4). During a down shift, the shift timing valve STV3 acts immediately to empty the trimmer valve TV3 and release the brake BR3 substantially instantaneously.
