Title: Mobile radiography alignment device
Inventor: MACMAHON HEBER
IPC: H05G1/02
Filed: 1987-11-30
Granted: 1991-04-02
Abstract: ABSTRACT      An alignment device for use in mobile radiography.  In contrast to prior practice in which a film cassette is placed on one side of the patient, an x-ray source on the other, and it is left to the skill of the technician to approximate the necessary alignment, the present invention assures consistent alignment much more precise than is typically achieved.  The precise alignment allows regular use of a grid in mobile radiography which helps to prevent image deterioration caused by scattered radiation.  The precise alignment is achieved by providing an adaptable physical connection which when in the deployed condition, accurately establishes both the distance between the focal spot and the film plane and the alignment of the grid with respect to the central ray.

Title: Method and apparatus for the two-stage crushing of brittle material for grinding
Inventor: BLASCZYK GOTTHARDT
IPC: B02C25/00
Filed: 1987-12-01
Granted: 1991-06-18
Abstract: Abstract The invention relates to a method and apparatus for the two-stage crushing of brittle material for grinding using a roll mill and a mill connected after it in which a branch stream of the grit obtained in the sifting operation is returned to the roll mill and a further branch stream is returned to the second mill.  A first control circuit keeps the sum of the quantity of fresh material and the quantity of grit constant, whilst a second control circuit divides the quantity of grit into two branch streams in such a way that the drive power of the roll mill remains constant.
Patent CA-1335065-C (CA)
Inventor: ELLERS BERNE
IPC: D04H1/542
Filed: 1987-12-18
Granted: 1995-04-04
Abstract: A method and apparatus are disclosed for binding a nonwoven material by means of a binding agent requiring heat for activation, particularly for binding cellulosic fibers with a thermoplastic material.  The material is irradiated with an infrared radiation source, and surface burning of the irradiated material is prevented by passing a weak flow of air through the material.  Inclined walls guide the air flow through the material in an inclined path directed from the edge of the infrared radiation source and towards the center thereof.  Each infrared radiation source is surrounded by two side walls so that a space is formed between each side wall and the radiation source for the passage of the inlet air.          The cross-sectional areas of these spaces are together approximately equal to the cross-sectional area of a suction channel positioned opposite the spaces.  The air flow is controlled by means of two speed-regulated fans, one at the inlet and one at the outlet of the apparatus.

Title: Error detection member for an overspeed governor
Inventor: TALLMAN JACK A

Granted: 1991-06-11
Abstract: ABSTRACT OF THE INVENTION       In the fuel management system having an electronic computer (36) for operating a metering valve (50) through which fuel is supplied to operate a turbine engine (10).  A mechanical governor (116) responsive to the rotation of a turbine by the combustion of fuel supplied to chamber (16) allows a portion of the fuel supplied to the metering valve (50) to return to a pump supply (30) when the rotational speed of the shaft (20) connected to turbine (18) exceeds a preset valve.  An error detection member (440) responds to a mismatch between the force output of a flyweight (130) and a speed feedback roller (408) to prevent the return of the entire quantity of fuel to the pump supply (28) and thereby assure a minimum quantity is always available to operate the turbine engine (10).

Title: Printer hammerbank cam drive having pulsed startup
Inventor: BARRUS GORDON B
IPC: B41J2/245
Filed: 1988-06-17
Granted: 1992-03-03
Abstract: Abstract of the Disclosure In a dot matrix line printer in which an elongated hammerbank and an opposite counterbalancing assembly are driven in opposing reciprocating fashion by a motor driven cam,  the size  of  the  cam drive  motor  and  the  current requirements thereof during startup of the printer are greatly reduced by applying current pulses to the motor in a pattern synchronous with the resonant frequency of the reciprocating cam driven system.  The current pulses which are considerably smaller   in   amplitude   than   the   continuous   current conventionally used to produce startup are generated during alternate half cycles of the resonant frequency, causing the cam to rock back and forth until eventually the peak resistance presented by opposite lobes on the cam and the consequent maximum compression  of  springs within  the cam followers coupling the cam to the hammerbank and the counterbalancing assembly is overcome.  Thereafter, a continuous current of appropriate value is applied to the cam drive motor to produce reciprocation of the hammerbank at a desired steady state speed.

Inventor: WATARAI SHINICHI
IPC: G03G15/00
Filed: 1988-08-11
Granted: 1993-05-25
Abstract: ABSTRACT OF THE DISCLOSURE           In a high speed printing station, cut sheets are separated one by one sequentially and transferred through the printing station.  When a sheet jamming occurs in the feeding unit therein and all of sheet transport means are stopped, the previous sheets remaining and moving in the printing and ejecting units are wasted and components in the printing unit are contaminated by toner powder.  The control method of the present invention comprises steps of (a) detecting the sheet jamming occurred in the feeding unit by a first sensor, (b) stopping the transport means in the feeding unit only, (c) continuing operation of other transport means until the second sensor in the ejecting unit detects an ejection of all previous sheets in the printing and ejecting units, and (d) stopping the other transport means.  The sheets except the jammed one becomes available for use and the contamination by toner powder is avoided.

Abstract: Water is added to pre-steamed flaked oatlets which are then blended together for approximately 30 minutes and allowed to condition for a further period of 45 minutes.          The conditioned oatlets  are  fed to an extruder cooker where they are subjected to frictional and shear forces which raise the temperature at the die exit to 95°C and raise the pressure to 90 psi.  At the die face the exudate has a moisture content of 18.5% by weight and it is cut into pellets having a weight of 0.1 g.   The pellets are conveyed to  flaking rolls where flakes are formed and dried to a moisture content of 7%.  The flakes are blended with 25% by weight of the pre-steamed oatlets to form an instant water reconstitutable cereal product.
