Abstract: 1,239,510. Measuring voltage potentiometrically. LEEDS & NORTHRUP CO. June 27, 1969. [July 2, 1968], Heading G1U. [Also in Division H3] In a null-balance servosystem e.g. for a potentiometric recorder, the difference signal amplifier includes a reactive feedback network which restricts the amplifier bandwidth and an amplitude limiting circuit which limits the amplifier output and at the same time renders the feedback network ineffective when an overload occurs so as to prevent the amplifier becoming disabled by the overload. In the potentiometric measuring system of Fig.1 the input signal at 13 is applied through filter 14 to one input of a differential preamplifier 18, and a reference signal across resistor 19 is applied to the other input. The preamplifier output is passed to a further amplifier 25 supplying motor 26 which drives the tap 45 of D.C. energised potentiometer 44. Amplifier 47 connected to the potentiometer tap and to a damping circuit 49 provides the reference signal across resistor 19. The motor also drives a pen recorder (not shown). The amplifier 25 has both a resistive feedback path 30, 31 and an R-C bandwidth-limiting feedback path 28, 29. The time constant of the R-C path preferably equals that of motor 26, and its presence minimises the "dead-zone" of the system. In parallel with the feedback paths is a limiting network 23 which is normally nonconductive, but which conducts to shunt the feedback paths on occurence of an overload of either polarity.

Abstract: 1,258,921. Counters. ENGLISH ELECTRIC CO. Ltd. 13 May, 1969 [20 May, 1968], No. 23888/68. Headings G4A and G4H.  Pulses counted during one cycle are transferred to a display device 31-33 in the early part of the succeeding cycle, pulses occurring during said early part being registered in a separate store 7 before transfer to the main counter 13, 18, 21. The invention is applied to continuous measuring of the circumference of a work piece 86, Fig. 2, the cycles being measured off by the passage of a marker 93 past a transducer 94. If switch 69, Fig. 1, is connected to 0 at source 60 then pulses from counting pulse source 1 are counted between successive trigger pulses from 2. The first cycle after operation of manual reset key 59 is ineffective except to set flip-flop 54 to 0. The next trigger pulse sets 54 to 1 to connect binary counter 7 to receive pulses from source 1. The third count pulse at 7 generates a latch count signal on line 46. This signal transfers the count registered during the previous cycle in stages 13, 18, etc., to display tubes 31-33. The seventh count pulse at 7 signals lead 49 to clear the count stages 13, 18 etc. The ninth count pulse returns flip-flop 54 to 0 and counter 7 to zero. The tenth pulse-is sent direct to tens stage 18, and subsequent pulses to units stage 13 with the usual carry as required. The next and subsequent trigger pulses restart the sequence. If switch 69 is connected to 1 at source 71 then a binary counter 62 controls flip-flop 54 so that it sets to every tenth pulse from trigger source 2 and is reset by counter 7. The decimal point is indicated by a neon tube 98.

A buffer sheet 4, to be placed along the undersurface of a rigid sheet G carried by a roller conveyer 1, is positioned such that a portion 4b thereof projects vertically above the path of the rigid sheet G, the movement of the rigid sheet G causing the portion 4b to be folded about the leading edge of the rigid sheet G and the remainder of the buffer sheet 4 to be placed along the undersurface of the rigid sheet G. A driven brush or rubber roller 9 is adapted to engage the top buffer sheet 4 of a stack on a truck 5, and urge this buffer sheet 4 against a suction conveyer 10 which positions the buffer sheet 4 as above. The suction conveyer 10 comprises a suction box 20 and a perforated endless belt 14 driven by a motor 18. If a photo-cell 27 detects the absence of a buffer sheet 4 on the belt 4, a cylinder 7 is actuated to lower the roller 9 on to the stack, the roller 9 being lifted from the stack when the photo-cell detects a buffer sheet on the belt 14. A further photo-cell 28 stops the belt driving motor 18 after a time sufficient to provide the projecting portion 4b which is maintained vertical against a stationary folder 29 by means of an air nozzle 30. As a rigid sheet G approaches the buffer sheet 4 it actuates a switch 31 to energize the motor 18. After the buffer sheet 4 has been placed along the rigid sheet G, the two sheets are carried by the lower run 34 of a suction conveyer 32, from which the sheets are removed by rollers 51, 52 to drop, in an inclined orientation, on to a transverse roller conveyer 35. Brushes 39 are provided between the rollers 36 of the conveyer 35 to cushion the first sheet falling to the conveyer 35. The brushes 39 are then lowered by swing links 40, 41 connected to pneumatic cylinders 42, and the sheet is positioned against guide rollers 38 by driven rollers 44. The buffer sheet may be of paper, fabric, non- woven fabric, or synthetic resin whilst the rigid sheet G may be glass, metal or resin.

Crack proporgation is thereby diminished. The reinforcements are preferably continuous parallel filaments having an outer sheath comprising 20-30% of the filament cross-sectional area. In one embodiment a number of carbon or glass fibres are embedded in an epoxy resin and surrounded by a metal tube of hexagonal cross section, the tubes being bonded together by an adhesive matrix more strongly than they are bonded to their cores. Alternatively boron is deposited in successive layers on a substrate fibre from the vapour phase. One or more layers of carbon are deposited to reduce the adhesion between layers or between filament and matrix. Boron, boron carbide or silicon carbide may be deposited from the gas phase onto a high modulus carbon fibre. Filaments comprising core, sheath and interlayer may be extruded from polymeric materials and the filaments carbonised, the interlayer producing a weaker, less ordered form of carbon, e.g. graphite. Carbon filament precursors may be etched with nitric acid or, after pyrolysis, by heating in air. The core may be tubular.  The shear stress of the core/sheath interface may become, less as the applied tensile stress increases in the embodiment in which the sheath is a helical winding and the core/ sheath "bond" is due solely to frictional forces. A concrete matrix may be reinforced with steel rods or bundles of resin impregnated glass fibres.
