Patent GB-257352-A (GB)
Abstract: 257,352. Leask, J. P., and Warner, S. T. June 2, 1925. Testing viscosity of liquids.-The viscosity of a fluid is controlled by varying the temperature of the fluid and regulating the variation of temperature by the viscosity of the fluid itself. A fluid tank 1 is provided with a heater 2 supplied with a heating medium through a pipe 3 and valve 4 which may be hand controlled or controlled automatically by pressure. A pump 5 forces fluid from the tank through the pipe 6 to a place where the fluid is in use. A pipe 8 having a double constriction 7, 7<a> is connected to the pipe 6 on the discharge side of the pump and leads back to the tank 1. Pressure gauges 11, 12 are placed on opposite sides of the constriction 7. From between the constrictions 7, 7a a branch pipe 10 leads to the pressure regulator 4<1>. The greater the viscosity, the greater the difference of pressure on either side of the constriction, and consequently this pressure difference may be made to control the valve 4 in such manner that the greater the viscosity the larger amount of heating medium is passed, the effect being to reduce the viscosity. In a modification, the gauges 11, 12 are placed on opposite sides of a constriction in the pipe 6 and the valve 4 is controlled by hand. In other forms, a long length of the pipe 6 is included between the gauges; the heater is placed on the delivery side of the pump; and the method is applied to an open tank feeding by gravity.

The matrices 2 are pressed by a spring pusher 4 against a fixed abutment wall 6, and are pushed down one by one by a reciprocating finger 12 into a laterally movable cage 8, which co-operates with a feelermechanism 10. The finger 12 is carried by a slide 11, which is operated by a lever 13 and a cam. A locking-lever 17, pivoted in the wall 6, tends to move, by the action of a spring 18, beneath a shoulder 22 on the slide 11, so as to prevent the descent of the slide. The locking- lever is withdrawn through the action of a twoarmed lever 21 by the pressure, of a correctlypositioned matrix. According to the invention, a pawl 29, pivoted on the machine frame, prevents disengagement of the locking-lever until the pawl is raised by the shoulder 22 on the slide 11, and the slide is accordingly in its highest position. In a modification, the pawl 29 is replaced by a downwardly-extending finger on the shoulder 22.

Title: Electrical waveform peak amplitude discriminators
Inventor: GRANT BRIAN ERIC
IPC: G01R19/04
Filed: 1961-07-20
Abstract: 951,329. Peak voltage measurement. MINISTER OF AVIATION. July 20, 1962 [July 20, 1961], No. 26309/61. Heading G1U. An electrical waveform peak amplitude discriminator comprises a gate, threshold circuit opening the gate upon an input signal amplitude exceeding a first level, a threshold circuit closing the gate upon the input signal amplitude exceeding a second high level, and trigger means applying a pulse to the gate upon the signal amplitude exceeding or falling below the first level; so that the output of the gate develops a pulse only when the signal amplitude has previously risen above the first level but not above the second higher level. An input signal (Fig.2a) is applied to adjustable Schmitt trigger threshold circuits 1, 2 (Fig. 1) each producing an output pulse when the input rises above the respective preset threshold values A, B (Fig. 2a). The output of 1 (Fig. 2b) is applied to a bi-stable trigger circuit 3 to pulse it from the 0 to the 1 state, while the output of 2 (Fig.2c) is applied to pulse it from the 1 to the 0 state. The trigger output 3 is applied to a delay unit 4 of time T whose output (Fig. 2d) operates a gate 5 also receiving the output of 1 to open for the duration of the shaded areas, so as to admit any pulses in the output of 1 during the open period to counter 6; such pulses occurring only when the input amplitude rises above threshold A and has not exceeded threshold B since the preceding rise through A, so that the count represents the amplitude peaks in the range AB. In modifications delay unit 4 may be placed between the output of threshold circuit 1 and the input of trigger 3, or delay unit 4 may be omitted and a second output taken from threshold circuit 1 so that a pulse is derived when the input falls below threshold A and is applied to gate 5. For analysis of the distribution of peak voltage amplitudes of a repetitive waveform, the thresholds are fixed and the input passed through a variable gain amplifier and added to a variable D.C. bias, the waveform being examined using different levels of gain and bias, with the resulting count indicated by 6. In Fig. 3 the circuit of Fig. 1 has added a third threshold circuit 7 fed from the input responsive to a level C exceeding B whose output is applied to trigger circuit 8 from 1 to 0. The trigger is also operated from 0 to 1 by the output of threshold circuit 2, and its output controls coincidence gate 10 over delay 9 to open shortly after the 1 state and close shortly after the 0 state. The output of gate 10 is applied to counter 11 to register the peaks lying between thresholds A, B and may be interconnected with the input of counter 6 to register the total peaks exceeding threshold A. Further threshold circuits, triggers, gates and counters may be added to register peaks between further thresholds.

Abstract: 805,846. Moulding sheets from wood chips and resin. KREIBAUM, O. Aug. 29, 1956, No. 26375/56. Class 87(2). Apparatus for moulding sheets from wood chips and heat-hardenable resin comprises a compression plunger operating in a chamber, two opposite walls of which are formed by movable bands arranged to move in the same direction as the plunger only when the plunger has compressed the material a predetermined amount. The material 3 is supplied from a hopper 4 into a chamber 5, two walls of which are formed by endless bands 7 supported on heating plates 6 and rollers 8. In one embodiment, the reciprocating plunger 9 is connected by a pin and slot connection to thrust rods 10 which actuate a ratchet mechanism 12 to rotate the rollers 8 when the plunger 9 has completed part of its stroke. In another embodiment, stops 14 on the plunger abut against the release mechanism 15 of a brake 16 so that the material under compression in the chamber 5 frictionally drives the bands 7. In a third embodiment (not illustrated) the head of the plunger is resiliently movable against the main part of the plunger so that on movement of the head, caused by back pressure of material being compressed, the plunger initiates movement of the bands.
