Title: Electronic measuring apparatus with minimized quadrature components
IPC: G01R17/00
Filed: 1964-06-11
Abstract: 1,020,960. Bridge measuring circuits. SHEFFIELD CORPORATION. June 11, 1964 [June 14, 1963], No. 24299/64. Heading G1U. In a measuring circuit in which a null indication is observed through an amplifier and in which it is sufficient to observe the inphase component only, the quadrature component of the amplifier output is observed, shifted 180 degrees in phase and fed back to the amplifier input. In the circuit of figure 3 capacitors 32, 34 are compared with the aid of a ratio transformer 38 in a bridge circuit. The bridge output, however, will have a component in quadrature with the supply (due, for example, to losses in the transformer) as well as the inphase component which it is desired to reduce to zero. Consequently at low values of inphase signal, when high amplification is required, the amplifier 40 will be saturated by the quadrature current. The amplifier output is fed to a phase sensitive null detector 41 and, after shifting 90 degrees, to a quadrature detector 44 which feeds a D.C. signal at X, X<SP>1</SP> to the auto-nulling circuit 46. The auto-nulling circuit (figure 4, not shown) receives the main bridge supply at Z, Z<SP>1</SP> which drives transistors 60, 62 in emitter follower connection to feed the variable gain amplifier stage comprising transistors 64 and 66. The gain depends on the emitter voltages at transistors 64 and 66. The D.C. signal at X, X<SP>1</SP> is connected to the bases of transistors 68 and 70 which are in emitter follower configuration and drive transistors 72 and 74. Transistors 76 and 78, which are driven by transistors 72 and 74 control the emitter current of transistors 64 and 66 and hence the amplitude of the output signal which passes through the emitter follower formed by transistors 80, 82 and the summing circuit 84. The output is then shifted 90 degrees at 86 and fed to the amplifier input with the bridge error signal through the summing network 88.

Filed: 1969-05-14
Abstract: 1,270,823. Automatic winding machines. KISHINEVSKY NAUCHNO - ISSLEDOVATELSKY INSTITUT ELEK TROPRIBOROSTROENIA. 14 May, 1969, No. 24517/69. Headings DIF and D1J. A device for winding microwire comprises a reciprocable multi-position turret head 1 having a plurality of winding spindles 3 which are connectable to a drive motor 4 by means of gears 18-22, and clutches 43, 44 such that the spindle 3 for carrying the bobbin 2 on which wire is to be wound, and the spindle 3 carrying the bobbin next to be wound, are rotated. The clutches 43, 44 are engaged or disengaged on rotation of the head 1 by axial movement within the spindles 3 of pins, the ends of which engage a non-rotating cam plate 46. Reciprocation of the turret head 1 by a hydraulic cylinder 10 operated by limit switches 7 provides traversing of the glasscovered microwire upon the bobbin 2, and rotation of the head is produced by a second hydraulic cylinder 11, engaging a ratchet wheel 9 when next the head reaches its innermost position after a signal from a counter 6 indicates that the bobbin is fully wound. On rotation of the head 1, the wire is caught between the next bobbin 2 and its boss 42, so that it is broken off as winding on this bobbin commences. The speed of winding may be adjusted between 5 and 800 metres per minute by controlling the motor 4 and charging from one ratio to the other of the twospeed gear train 18-22. Traverse speed is adjusted by means of throttle valves 16, 17 and the initial traverse on a bobbin may be longer than those of succeeding layers to provide a free end of the microwire for measurement. A number of time delay relays are provided in the control circuit (Fig. 3, not shown) to ensure that winding is not commenced on a new bobbin until glass capillary with an intact microwire core has been produced for a definite period, and that traversing is not commenced until intact wire has been produced for a further period. Waste capillary is thus wound up on the initial bobbin, and only intact wire is wound on subsequent bobbins.

Abstract: 920,846. Cleaning spinning &c. machines. HUBERT SOHLER G.m.b.H. July 14, 1960 [July 15, 1959; Oct. 29, 1959], No. 24622/60. Class 120 (3). A travelling machine for cleaning a spinning frame comprises a blower with cleaning apparatus operable to remove dust and waste fibre accumulating on a filter screen on the intake or suction side thereof. A collector mounted on the machine receives the removed dust &c. and then expels it, at a predetermined point in the travel of the machine, through a normally closed discharge opening. In the apparatus shown in Fig. 2, dust &c. laden air enters a casing 5 through an adjustable opening 6 and air filtered by a screen 7 is delivered through one or more ports 4 and ducts (not shown) to the frame by the vanes 3 of a blower motor 1 running on overhead rails 2. The screen 7 is cleaned continuously by a brush 8 mounted on endless belts and the dust &c. is delivered into a collector 9. A lever 25 is periodically operated by engagement with a stop 13 to open a closure flap 10 so that the contents of collector 9 fall into a stationary receptacle 14 and, simultaneously therewith, to close the top of the collector by flaps 15 so that the collector is isolated from the suction side of the blower. The cleaning machine shown in Figs. 3, 4 and 5 travels in one direction along a circular track. The collector 9 is emptied laterally and dust &c. is urged towards the discharge opening along an inclined base insert 16 at the top of which is the outlet of a blowing duct 17. A normally closed valve 19 is mechanically connected to closure flap 10 so that additional air from duct 17 assists the transfer of material to the receptacle 14 (and also renders unnecessary the use of flaps 15, Fig. 2). The blower delivers air through ducts 20, Fig. 5, and suction is applied through ducts 18. In a further modification, Figs. 6 and 7 (not shown), suction ducts 18 discharge into the space between the laps of the belts carrying the brush 8.
