Title: Integrator device
Inventor: FRISBY CLINTON D
IPC: H03M1/00
Filed: 1967-09-30
Abstract: 1,204,509. Selective signalling; counters. INFOTRONICS CORP. 30 Sept., 1967, No. 44634/67. Headings G4A and G4H. [Also in Division H3]  A signal peak integrator, e.g. of the type used in chromatography analysis includes a voltage to frequency converter 20 feeding a counter 55, a variable gain amplifier 15 for range-changing, and a variety of noise rejection and correction circuits, of which the base line correction circuit 50 is only rendered active between signal peaks. Range switching.-A pair of triggers in level sensor 25 are set to respond to different voltages, e.g. 25 V and 2 V after amplification. The gain of amplifier 15 is reduced by a factor of 10 when the first trigger responds, thereby reducing the amplified signal to 2À5 V, and the high gain condition is not restored until the amplified signal drops to 2 V, so that hunting is avoided. In the low gain condition switch 56 feeds pulses to the units decade of counter 55, but in the high gain condition, pulses are fed directly to the tens decade. A delay is introduced when decade switching to avoid errors caused by the finite response time of amplifier 15. Peak detection.-RC network 24 differentiates the input signal and amplifier 28 provides a signal above or below a reference level to set one of triggers 34, 35 depending on the direction of slope of the input. The slop detection circuit is disabled by level sensor 25 during the central, high value portion of each peak. Amplifiers 21, 28 include noise rejection filters. Base line drift correction.-During the intervals between peaks the output of converter 20 drives a servo system 46, 47 to adjust a potentiometer 48 if this is necessary to bring the output frequency of converter 20 to a predetermined value. Noise rejection &c.-Plateau timer 80 detects a positive slope followed by an indeterminately long zero slope to stop the counting and reset the counter and memory 60. Minimum peak timer similarly prevents the integration of short noise spikes. Threshold level detector 84, in conjunction with peak detector 41 detect the occurrence of a large peak overlapping a smaller following peak, i.e. when, at the end of a peak, the output of converter 20 is greater than its base line value, and restarts the counter 55 read-out and counting cycle so that both peaks are integrated separately. Positive re-entry circuit 86 performs a similar function for small unresolved peaks preceding large peaks. Counter.-In the high gain condition pulses on lead 45 are fed via NOR gate 400, Fig. 4B to the units decade. On reaching a count of 9, the units decade opens NOR gate 403 to inhibit NOR gate 402 and enable NOR gate 401 so that the next pulse on lead 45 advances the units and tens decades by one via gates 400, 401. In the low gain condition, lead 95 receives a binary one to inhibit NOR 402 and enable NOR 401 so that input pulses, each representing 10 units are supplied directly to the tens dacade. The units decade also continues to count, but the carry circuit is disabled.  (For Figures see next page.)

The pump unit shown in Fig. 1 comprises an impeller 21 driven by a motor 29, the flow-rate being adjustable by means of a by-pass valve 27 having a slotted head 26. A mixer valve T is adjusted by a reversible motor 1 connected to it through planetary reduction gearing 4, limit switches 15, 15 for the two directions of  rotation being operated by a cam 13. The mixer valve T co-operates with inlets B, E and outlets A, S, Figs. 1 and 4, which are connected to a central heating installation comprising a boiler 41, radiators 43 and, optionally, an indirectly heated hot water tank 44. A room thermostat 45 controls the position of the mixer valve T and therefore the extent to which cooled water returning from the radiators 43 via the inlet B is mixed with heated water entering inlet E from the boiler 41 before the mixture is returned via outlet S to the boiler. Water returned from the hot water tank 44 may be mixed with the water returned from the radiators 43 or, as shown, kept separate from it. In other embodiments, the temperature at the boiler output or at the radiator input is also sensed and used for controlling the mixer valve. In the pump unit shown in Figs. 10 and 12, the , pump impeller 21 and the mixer valve 46 are mounted side by side. The by-pass valve 55 for adjusting the pump flow-rate is disposed in a cylindrical portion 48 of the by-pass duct 47, 48. The mixer valve 46 may be operated manually by means of a handle 49 or by means of a motor 100 and reduction gearing via a clutch comprising a leaf-spring 104 riveted to the handle, the leafspring being put into engagement with a pin 105 so as to transmit the drive from an arm p.

A method of cooling rolled wire comprises laying the wire in constant diameter overlapping turns along a conveyer by means of a rotatable laying arm, and harmonically vibrating the arm and/or the conveyer at right-angles to the direction of advance of the conveyer with a frequency in the ranges:- 0À5 # to 1.5 f 2.5 f to 3.5 f 4.5 f to 5À5 # and so on where f = u/4#d, u being the wire speed in m./sec. and d the turn diameter in metres, the amplitude of vibration being 1 to 20% of the turn diameter, so that successive turns are displaced towards opposite sides of the conveyer. Frequencies in the higher ranges offer no advantages over those in the lower ranges and even multiples of the basic frequency will not necessarily avoid close spacing in the marginal zones.

[Also in Division F2] A ropeway 1 for a ropeway supported endless conveyer belt 3 comprises two parallel loops of rope interconnected by distance rods 2 to form an endless band providing an upper load-bearing lap and a lower return lap and a driving drum c for the band comprising an axle 11 carrying a set of radial drums 14 having driving parts 15 for the loops and being, between their driving parts pivotally mounted about an axis perpendicular to the axle 11 so that the driving diameters for the loops are free to change in opposite senses to balance uneven tensions in the loops. The two loops of the ropeway are formed from one length of steel cable, the middle section 1a of which runs across the conveyer track and is positioned and adjustably retained by pulleys 5 and a clamp 7 on a cross-member E and the two ends of rope from the pulleys 5 run over the driving and reversible return drums C, D, forming the loops, around pins 6 on the member E and are coupled at B to the opposite loop. The arms 14 of the driving drum C are pivotally mounted to the periphery of a disc 12 carried by the axle 11 and parallel to the axle 11. Each arm 14 comprises the two fixed rubbercoated bearing sections 15 with flanges 16 to prevent the rope slipping from the seating and a roller 17 on which the belt 3 is supported. Limit discs 13 are slidably adjustable on the axle 11 to limit the amount of taper of the driving drum in operation and for resetting the arms parallel. The return drum D comprises a freely rotating centre drum constructed of metal strips, for the belt 3 and a freely rotating flanged disc at each end for the loops of rope. The rope is supported between driving and return drums by further drums or discs. The belt is supported freely on the distance rods 2 or may be bolted to troughing supports 18 provided on the rods.
