Abstract: 462,128. Cutting sugar cane. BLAIRS, Ltd., and WHITE, A. Sept. 2, 1935, No. 24447. [Class 5 (i)] An apparatus for cutting and shredding sugar cane comprises a casing 2, having an inlet 3 for the cane and an outlet 24 for the cut cane, a rotating shaft 7 extending transversely of the casing, a plurality of transversely extending blades 8 carried by the shaft and a plurality of yieldably or resiliently mounted .transverse blades 12 in close proximity to the circumferential path struck by the rotating blades on the shaft 7. The blades 8 are preferably reversible and are carried on spiders 10, the arms of adjacent spiders being staggered with respect to each other. Alternate cutters of each spider may be straight edged and the intermediate cutters serrated. The blades 12 are carried between curved arms 11, a number of such units being independently mounted on the shaft 11<a>. Each unit is connected by a link 15 and bell-crank 16 to a strong spring 17. The blades 12 are accommodated in slots in the inner faces of the arms 11 and are bolted to lugs projecting from the said faces, the bolt holes being elongated to permit adjustment. In a modification, Fig. 5, the ends of the blades 12 are received in longitudinal recesses 21, and are spaced by packing pieces 22. A baffle 2<a> directs the cane to the cutting zone and a baffle 25 prevents the cut cane from being carried back over the rotating cutters. The apparatus may be located between two crushing-mills, or it may discharge on to a conveyer 24<a> which carries it to the first mill or crushing-rollers.

Title: Improvements relating to clutches for transmitting rotary motion
Inventor: SINCLAIR HAROLD
IPC: F16D23/10
Filed: 1954-08-23
Abstract: 773,545. Magnetic clutches. S.S.S. GEARS, Ltd. Aug. 10, 1955 [Aug. 23, 1954], No. 24522/54. Class 35. [Also in Group XXIV] A Legge clutch of the type disclosed in Specifications 354,711 and 410,083, [both in Group XXIV], comprising a toothed clutch ring 1 on a shaft 2 and an intermediate toothed clutch member 8 helically splined at 7 on a shaft 6, is provided with means by which the engagement of the clutch teeth is initiated by magnet force. In the form shown, a number of U-shaped permanent magnets 5, Figs. 3, 4, are carried by the shaft 2, and the intermediate clutch member 8 carries a notched armature ring 15 and a copper eddy current ring 16. The magnets 5 exert an axial force to the left of Fig. 3 on the armature ring 15 &c., tending to engage the clutch teeth. When the shaft 2 rotates more quickly than the shaft 6, the clutch teeth are in nuzzling engagement and slide freely over each other, while a drag torque produced by the magnetic interaction of the magnets 5 with the armature 15 and eddy current ring 16 tends to oppose the axially directed magnetic force by screwing the intermediate clutch member 8 to the right on the shaft 6. As the speed of the shafts 2, 6 approach synchronism, the drag torque ceases, and the clutch teeth are drawn into initial engagement by the axial magnetic force. Mechanical interaction, as the speed of the shaft 6 increases beyond that of the speed of the shaft 2, then screws the clutch member 8 to the left to fully engage the clutch teeth. If the speed of the shaft 6 decreases below that of the shaft 2, the intermediate clutch member 8 is screwed to the right to disengage the clutch teeth. In one modification, Figs. 1, 2 (not shown), an unnotched armature on the intermediate clutch member carries the copper eddy current ring. Alternatively, electromagnets may be used in place of permanent magnets.

Title: An automatic trigger level control circuit
IPC: H03K9/06
Filed: 1970-05-21
Abstract: 1294607 Automatic level controlled triggering Circuit TEKTRONIX Inc 21 May 1970 [9 June 1969] 24575/70 Heading H3T A triggering circuit comprises a slicer 18 in a feedback circuit of an amplifier 10 and biased to pass in a forward direction an incremental portion of an input signal centred at a selected fraction of the output of a peak signal level detector 14 fed from the output of the amplifier, the selected fraction being applied to a trigger circuit 16 and means being provided to increase the gain of the amplifier during the slice to offset the voltage drop in the peak detector. The slicer shown receives its bias via transistors 58 and 66 from a potentiometer combining the outputs of positive and negative peak detectors 42, 44 so that the slicer passes the input signals derived from 26 during the small signal increment around the bias level while both diodes conduct. During this conduction the current drawn from point 26 reduces the feedback in amplifier 10 so that the gain increases sufficiently to overcome the voltage drop in the peak detector. The slice is applied to the combined input-output point 40 of amplifier 58, 60 and is passed to the Schmitt trigger 16 having a small hysteresis range lying within the slice. The resulting output wave 128 is differentiated by a transformer 96 to produce output spikes 130 having a polarity determined by which primary winding is selected by a switch 98. By adjusting the potentiometer the spike will occur at a selected fraction of the peak amplitude, independently of the value of the peak. An input capacitor may remove the D.C. component of the input signal and an input amplitude limiter may be provided (Fig. 3, not shown).

Abstract: 1,248,880. Driving pumps. GENERAL MOTORS CORP. May 21, 1970 [June 2, 1969], No.24587/70. Heading F1C. [Also in Division F2] A liquid-cooled disc brake assembly (see Division F2) includes a wheel hub 42 to which are splined rotary brake discs 38 interleaved with fixed discs 36 splined to the cover 20. An internal gear 56 formed on the wheel hub 42 meshes with a gear 68 integral with a pump impeller 64 to drive the impeller. The pump impeller circulates cooling liquid which receives heat from the braking surfaces in chamber 24 and is discharged through a conduit 70 to a heat exchanger (not illustrated) from which it returns at 72 to the brake assembly. The cooling liquid serves to lubricate the bearing surfaces of the pump impeller drive member 66. In the modification of Fig.3, there is no internal gear 56 on the wheel hub 42. Instead, the hub splines 122 drive an idler gear 118 which in turn drives a gear 114 having a quill shaft connection 116 with the impeller 110. The impeller is located in a pan-shaped pump housing 102 secured to a backing plate member 104 by a central bolt 106. The pump housing 102 is closed by an inserted cover-plate 124 through which passes the bolt 106 and, surrounding the bolt, the quill shaft. The idler gear shaft 120 is mounted at one end in an internal lug of the backing plate member 104 and, at the other end, in the pump housing cover-plate 124. The pump is driven, through the gearing, at a substantially higher speed than the hub.

Title: Pulse amplitude analysers
Inventor: LEWIS IAN ALEXANDER DARROCH
IPC: G01R29/02
Filed: 1950-10-12
Abstract: 696,229. Electric tests. MINISTER OF SUPPLY. Oct. 4, 1951 [Oct. 12, 1950], No. 24904/50. Class 37. [Also in Group XL (c)] A pulse amplitude analyser comprises means for plotting the amplitude peaks of an input pulse train as charged areas on a surface the plots being subsequently analysed by scanning them in a series of different amplitude ranges. The Figure shows a pulse amplitude analyser in which in the " record " position shown the input pulse train is applied at 1 via a peak brightener circuit to the grid of a storage cathode-ray tube 6 and also via switch 8 to the Y-deflecting plates 9. The X-plates 12 are connected to a single sweep time base circuit 14 so that a plot of the peaks of the pulses is produced as locally charged areas on the screen of the cathode-ray tube with time-amplitude co-ordinates. At the end of a sweep from timebase 14 a signal is transmitted via lead 35 to change over controller 30 to the " read " position and switches 4, 8, 13 and 19 changeover. The screen of the cathode-ray tube 6 is now scanned in a series of adjacent time-base sweeps each at a different level by the effect of time-base 15 and step-wave generator 11. Pulses are produced on the pick-up plate 17 as each plot made in the recording operation is scanned, these are amplified in unit 18 and fed to gate circuits 20, 20a, &c., each of which is opened sequentially by the step-wave generator 11 so that each channel receives pulses corresponding to pulses lying within a particular amplitude range in the input pulse train. The pulses in each channel are counted by a corresponding counter 21, 21a, &c., and they are also fed to pulse rate circuits 22, 22a, &c., which produce output signals having an amplitude proportion to the pulse rate in that channel. This signal is connected via gate circuits 23, 23a, &c., which are controlled from step-wave generator 11, to the Y-plates 24 of a display cathode-ray tube 25 and X-plates 29 of which are deflected by the step-wave generator 11. Thus the beam of the cathode-ray tube 25 is deflected in steps each of which corresponds to a given amplitude range and the pulse rate in that range is indicated by the Y-plate deflection of the beam. At the end of a " read " operation the generator 11 transmits a signal to change the controller 30 to the " record position.
