A circuit for producing a D.C. output current which remains proportional to an A.C. input signal despite variations in load impedance comprises a series regulator transistor 16 controlled by two further transistors 13, 14. Variation in A.C. input at 12 is rectified and fed via transistor 13, to produce a proportional current through transistor 16. Any variation in load across terminals 17, 18 varies the drive on transistor 14 to effect a rastering control on transistor 16 to maintain the output current proportional to the input signal. As shown the output current is proportional to input voltage, but the circuit may be modified for a current input by the inclusion of a resistor across the transformer, Fig. 2 (not shown).

In a system dispensing printed indicia (e.g. printing postage validating marks-'stamps'- direct on to envelopes in an office) a remote central station totalises the monetary value of the indicia dispensed. The link between the central station and the dispensing office can be via a conventional telephone channel. The central station can be arranged so that it prevents further indicia being dispensed when the credit for a dispensing office has been exhausted. When several dispensing stations are monitored by the same central station either individual communicating links can be used or a common link can be used with each dispensing office being arranged to precede each of its transmissions by an identifying signal. No detailed circuits are described.

Title: Speed sensing devices

Filed: 1974-09-09
Abstract: 1500699 Measuring speed electrically MOLINS Ltd 8 Sept 1975 [9 Sept 1974] 39188/74 Heading G1N(A) In a speed sensing device the speed of member 1 is compared with that of a reference member 101 by sensors 2 and 102 emitting pulses at a rate proportional to speed to counters comprising decade units 5, 6, 7 and 105, 106, 107 respectively, each counter providing an output whenever a pre-selected number of pulses is registered and being resettable by an output from either. The device may be used to sense when a bobbin supplying paper to a machine is becoming exhausted, the member 1 rotating with the bobbin and member 101 with the drive-shaft of the machine. The sensors emit pulses at the same rate for the same speeds but decade switches 9, 11, 13 connected to digital outputs 8, 10, 12 are set to a number greater than the setting of decade switches 109, 111, 113. The ratio of the pre-set numbers is such that when the bobbin is nearly' empty an output is produced at terminal 16X before an output at terminal 116X, the speed of the bobbin having increased due to decreasing radius of the outer-most layer of paper. This output resets counters 5, 6, 7, via OR circuits 19, 20, 21, and inverter 22 and resets counters 105, 106, 107 via OR circuits 19, 20, 119 and inverter 122. A D.C. input at terminal 26 maintains energization of output terminal 23 via OR circuits 20 and 19. Terminal 23 is connected to control circuits of a bobbin changing mechanism  and a signal on line 24 when the change is completed discontinues the signal on terminal 23. Each sensor comprises a perforated ferromagnetic disc 1 and a magnetic sensing head 2. To increase the pulse rate a second sensing head 2A may be used. To provide a preparatory signal to the bobbin-changing mechanism a further set of decade switches may be connected to counters 5, 6, 7 set to a smaller number than switches 9, 11, 13.

The first bearing assembly 12 includes an hydraulically actuated wedge 19 which is slidably received in a tapered slot 16a in the bearing housing 16 and is employed to releasably secure the bearing assembly during coiling of the strip on the mandrel. The sled 23 supports the inboard end of the mandrel in bearing assemblies 21 and 22 and is reciprocable along guideways 25 by an hydraulic cylinder 27. The bearing block 28 of the assembly 21 which forms part of the base 26 of the reel is releasable secured to the bearing assembly on the sled by an hydraulically operated wedge 30 (Fig. 2). The expanding mechanism of the mandrel (not shown) is actuated by an hydraulic cylinder 33 through pivoted arms 36 which reciprocate a bearing block assembly 38 and the mandrel actuating rod 39. The mandrel is rotated by a motor through gearing 42 and a splined shaft 43. A stripper plate 45 engages the coil when the mandrel is retracted to facilitate its removal from the mandrel whereupon it is transported from the reel by a coil car 46.

Abstract: 876,814. Photo-electric detecting devices. BRITISH NYLON SPINNERS Ltd. Nov. 18, 1959 [Dec. 13, 1958], No. 40242/58. Class 40(3) [Also in Group IX] Apparatus for the manufacture of staple fibre in which a bundle of continuous filaments is fed towards a cutting zone and is cut by a knife into tufts of staple fibre and in which predetermined, e.g. overlong, fibres or filaments are detected and the tufts containing such fibres or filaments are separated from the main production of the cutter, the presence of said predetermined elements produces an electrical signal which operates means for sorting the tufts of staple fibre and segregating the tufts containing the predetermined fibres from the other tufts produced by the cutter. The uncut filaments are fed through a central opening 3 to a radial channel 4 of a high speed rotor 1 and are normally cut by a blade 11 in the manner of a Beria cutter as described, for example, in Specification 289,028. Any residual portion due to an incomplete cutting operation produces a pulse from a photo-cell 6 in detecting apparatus comprising a light source 7, slit system 8 and mirrors 9. A magnetic member 23 produces during each revolution of the rotor 1 a pulse at a time corresponding to that at which a pulse could be produced from the photo-cell 6 due to uncut fibres or filaments which will appear as overlong elements of the following tuft. If a pulse is produced from the cell 6, a coincidence circuit 25, Fig. 4, is operated and, via an amplifier 26 actuates a counter member 29. The further pulse which is passed from the amplifier 26 to an electronic latching relay 27 overrides the pulse which is applied from the magnetic member 23 also to the relay 27 which through amplifier 28 operates a solenoid relay 18 to move a vane 14 to guide the subsequent tuft, which will have a proportion of long fibres, through a channel into a reject container. If a pulse is not produced by the photo-cell 6, the pulse from the member 23. operates the latching relay 27 to its normal condition in which relay 18 is released to restore the vane 14 to the position in which the output of the cutter is fed to the channel for normal tufts.
