IPC: G01R1/28
Abstract: 1,051,797. Voltage measurement. LEEDS & NORTHRUP CO. June 23, 1965 [July 2, 1964], No. 26649/65. Heading G1U. In an arrangement for measuring voltage (e. g. that produced by a thermocouple 30) by means of a potentiometer arrangement the voltage is balanced across a measuring slidewire 34 energized from a voltage source 33, the slidewire tapping being adjusted by a motor 17 which is driven in response to an error voltage via a detector amplifier 10. The arrangement incorporates, in order that the range of the apparatus may be adjusted, an adjustable current shunt, comprising a shunting slidewire 37 having two leg connections 38, 39 one including the measuring slidewire 34. An attenuator for the detector amplifier includes an attenuating slidewire 48 having two leg connections 49, 50 one of which 50 is connected across the input circuit of the detector amplifier so that a selected fraction of the error signal is applied thereto. A mechanical arrangement 52 is used to adjust the shunting and attenuating slidewire together so that the fraction of the error signal applied to the detector amplifier is maintained substantially constant independently of the current flowing in the measuring slidewire. The system may also incorporate an arrangement 32 for adjusting the scale zero. A voltage to be subtracted from the voltage being measured is tapped off the regulated power supply 60 by means of resistive chains providing 10mv and 1mv steps and a calibrated slidewire arrangement 63.

Abstract: 1,227,413. De-watering sewage sludge. CHEMISCHE WERKE ALBERT. 20 March, 1968, No. 13561/68. Heading B1D. Sewage sludge is de-watered by filtration inside a container I having a porous bottom 2, settling of the sludge taking place within the container and supernatant liquid 8 being drawn off. Settling is facilitated by the addition of flocculating agent to the sludge before its introduction into the container or by producing turbulence in the sludge in the container by aeration or stirring. Filtration occurs through a travelling band filter 4 (provided with cleaning sprays 5) arranged beneath the porous bottom of the container. Settled sludge cake 7 may be fed to a vacuum drum filter, Fig. 4 (not shown) having a filter cloth passing round the drum and round idler rollers. The container may take the form of a sack, the bottom at least of which is of a porous synthetic plastics fabric.

Abstract: 1,228,410. Control of D.C. motors. MOBILITY SYSTEMS Inc. 31 Oct., 1968 [22 Jan., 1968], No. 51588/68. Heading H2J. [Also in Division G3] The speed-torque characteristic of a shuntwound motor is modified by decreasing the field energization as the speed increases. The armature A is supplied from a variable voltage source 10 and drives a tachometer generator TG. The source 10 and the output of tacho. TG are connected to the inputs of a differential amplifier A2, the output of which feeds the field coil F. A delay circuit 12 is included between the tacho. TG and amplifier A2 so that the field weakening is not applied during initial starting. In a modification (Fig. 3, not shown) the speed voltage is derived from the back e.m.f. instead of the tachometer generator. In a further embodiment (Fig. 4, not shown) in which the tachometer generator TG also supplies a feedback signal in a retroactive speed control system (Division G3) means is provided for regeneratively braking the motor and also for reversing. During braking the motor acts as a generator to charge a battery (B2) which supplies an inverter/ rectifier circuit to recharge a main supply battery (B1). In a modification (Fig. 4b, not shown) the motor supplies a second motor acting as a generator to recharge the main battery (B1) directly.

Abstract: 1,230,803. Control of D.C. motors. BROWN, BOVERI & CIE A.G. 10 June, 1968 [8 June, 1967], No. 27562/68. Heading H2J. In a system in which the armature of a separately excited motor 1 is energized through rectifiers 3, in the event of abnormal armature current the field 9 is disconnected from the supply and is shunted by a circuit which permits its gradual decay or momentary reversal. The object of the invention is to reduce the current in the armature circuit due to its inductance (4 is a smoothing choke) and so ensure blocking of the thyristors 3 when their triggering pulses are stopped due to a fault, such as loss of contact with a conductor rail in a vehicle system. As shown, the field is energized via thyristors 5, 6 whose triggering pulses are inhibited by an armature current detector (not shown), as are those for the armature supply thyristors 3. In addition, a thyristor 11 is blocked by commutating thyristor 15, and the field energy first charges a capacitor 13 and is then dissipated in resistor 14. A commutating capacitor 16 is held charged by auxiliary transformer 19. In Figs. 2 and 3 (not shown) the field thyristors are incorporated in a bridge network and thyristor 11 is dispensed with, and in Figs. 3 and 4 (not shown) the field 9 is shunted by a capacitor to form an oscillatory circuit which, at the appropriate instant, is short circuited by a thyristor.

Abstract: 1,266,044. Facsimile recording apparatus. M. ALDEN. 2 June, 1969 [26 Nov., 1968], No. 27714/69. Heading H4F. [Also in Divisions G1 and G2] In a facsimile recording apparatus a (plastic) cartridge 8, Fig. 1, containing a roll of recording paper 10, moist electrolytic recording paper in this embodiment, is positioned on flanges 6 and 7 of the base 2 of the facsimile recorder housing 1 which has a pivoted cover 3. In Fig. 1 the paper 10 if drawn by driven roll 28 and idler roll 27 along a passage formed by upper and lower walls 11 and 12 of the cartridge through the cartridge exit 30 and then through the housing exit 14. Facsimile signals are recorded line-by-line by means of recording blade 26 which presses the paper against a rotating helical electrode 17 on drum 16, the paper then being dried by heating pad 37. In this embodiment the roll of moist electrolytic paper 10 is entirely enclosed within the cartridge except for blade aperture 25, helix aperture 23 and cartridge exit 30 which prior to use are sealed with tape (41, Fig. 3, not shown). The recording paper is thus protected against evaporation and contamination. The cartridge may have two brackets extending from its lower wall into which the helix drum is snap-jilted, the cartridge and drum being placed in the facsimile housing as a unit (Fig. 3, not shown). Alternatively, the helix drum may be permanently mounted in a well formed integrally with the cartridge and the recording blade may be permanently mounted on the upper wall of the cartridge (Fig. 4, not shown). Further, the driven and idler rolls may be mounted within the cartridge (Fig. 5, not shown). In a further embodiment, Fig. 6, a photosensitive paper web 10d is mounted within the cartridge and is scanned line-by-line by a modulated flying light spot from scanner 50. The scanner may comprise a moving belt with a small aperture, or an intersecting linear and rotating helical slit, or a moving light source and a line of optical fibres. The cartridge is made of opaque material and the passage of the cartridge comprises chambers 45 and 48, formed by squeegees 43, 44 and 46, containing sponge blocks 47 and 49 respectively impregnated with developer and a fixative. Reference is also made to the use of electrostatic and thermally sensitive papers.
