[Also in Division G1] A weighing mechanism for use in conjunction with a two-speed feed arrangement comprises a weigh beam 10 coupled to a dashpot 11, the dashpot comprising a piston 13 movable by the beam 10 and adapted to displace fluid from one end of a cylinder 12 in which the piston slides to the other end of the cylinder through a pair of restricted passages 17, 18, one of the passages being more restricted than the other and the less restricted passage being closed during bulk feed and opened during dribble feed by a valve 23. The valve 23 may be actuated by an electr c solenoid 25 through a spring-biased crank lever 24 and the restrictions of the passages 17, 18 may be adjusted by adjustable plugs 21. A stop 27 may be attached to the crank lever 24 so that, during bulk feed when the valve 23 is closed and the dashpot provides " heavy " damping, movement of the beam 10 is limited, whereas during dribble feed, when the valve is opened and the dashpot provides " light " damping, movement of the beam is not restricted. A switch may be arranged to alter automatically the damping characteristic of the dashpot on change-over from bulk to dribble feed after a suitable time delay.

Abstract: 1494294 Projection readers NCR CORP 28 Nov 1975 [9 Dec 1974] 48993/75 Heading G2J In a projector for reading micro-images disposed on a single sheet, the image-bearing sheet 28 lies between the projector lens system 24 and a contact member 20, and contact member 20 is moved between a position in which the sheet 28 is free to move and a position in which it presses sheet 28 against the lens system 24 or a spacer 26 between sheet 28 and lens system 24, and contact member 20 is also tiltable with respect to the optical axis, but remains parallel to the plane surface of the lens 24 or spacer 26 during movement. Contact member 20, a condenser lens 18 and a light source with a reflector 16 are all mounted in a housing 10, together with mirrors (not shown) in the projection beam. A table 14 supporting sheet 28 forms the top of the housing 10 and supports sheet 28. Contact member 20 is of hollow frustroconical form and is closed at its upper, smaller end by a glass plate 29. The upper end of contact member 20 extends with clearance into an aperture 22 in table 14. Normally the contact member is urged upwards by springs and presses a part of sheet 28 bearing a selected image against the plane parallel glass plate 26, which is urged against lens system 24. The parts are aligned on the optical axis of lens system 24. The contact member 20 may be lowered against spring action by a cradle 32 with a handle 36 (which may be spring-loaded) pivoted at 38, so that the sheet may be adjusted to select another image. On release, the clearance between the contact member 20 and the aperture 22, and the pivotal movement of cradle 32, enable the contact member to adjust itself to the plane of the spacer 26. Spacer 26 may be omitted, the sheet 28 being pressed directly against the lower plane face of the lens system 24. In another modification, Fig. 4 (not shown), the contact member has cylindrical form (52) and is closed by a glass plate with a central flat surface (58) with a beveled edge (56), and means for lowering the contact member are omitted. Cooling means, including a fan, are provided. In a further modification, the table 14 is omitted. In all cases, cooling air may be supplied to a chamber in base 10 to apply pressure and cleaning action to the underside of sheet 28.

Suitable films may be made by evaporation of 18% Fe-82% Ni alloy in vacuo and heating at a temperature of at least 350 C. As shown in Fig.3, two thin magnetic films 12, 12<SP>1</SP> are subjected to a D.C. polarizing field in the hard direction by series connected windings 20 and to an alternating pumping field of frequency f in the easy direction by parallel connected oppositely poled windings 14, 14<SP>1</SP>. Detection windings 18, 18<SP>1</SP>, coaxial with windings 14, 14<SP>1</SP>, are similarly poled and connected in series to an amplifier 24 tuned to frequency 2f which is connected via a synchronous detector 26 to an indicator or recorder 28. The films may be flat or may be coated on glass-coated copper wire in which case the polarizing field may be generated by passing a direct current through the wire Fig. 5 (not shown). An A.C. polarizing field may be used, in which case a common coil at an angle of 30 to 60 degrees to the easy axis may be used to generate a field having components in the easy and hard directions. Common pumping and detection windings may be used with filters tuned to f and 2f being connected to the pumping generator 16 and amplifier 24 respectively. The detector 26 may be used to control current in compensating windings (not shown), the current necessary to null the field being measured being an indication of the field strength. Three magnetometers may simultaneously measure three different components of the field.
