Abstract: 1,095,740. Injection moulding chains. GEIMUPLAST PETER MUNDT KOMM. GES. Dec. 30, 1964 [Jan. 7, 1964], No. 52857/64. Heading B5A. [Also in Division F2] In a chain injectionmoulded from thermoplastic plastics material, each link consists of two coplanar arches 11, 12 each of which comprises an arcuate web 14 having an internal radius of curvature R<1>2 and terminating in splayed substantially straight limbs 15, and each web has a cross-section which comprises an inwardly directed portion that is a segment of a circle, and an outwardly directed portion that is substantially an isosceles triangle with its base coinciding with the chord of said segment and its apex rounded to define a rounded rib 21 at the outer periphery of each web, the radius R2 of said segment being equal to said radius of curvature R<1>2. The limbs 15 of the two arches in each link are connected by a cruciformsection cross strut 13 to counteract limb bending. The length of said chord of said segment is larger than the thickness of the limbs perpendicular to the plane of the arches at the strut 13. The cross-section of each limb 15 includes an inwardly directed triangular portion the vertex of which has an angle which increases along the limb towards the web. The rounded rib 21 is continued to extend completely around each link. The cross-sectional area of each link is substantially constant throughout its developed length. The mould used comprises four jaws simultaneously closed and opened at right angles to each other and at 45 degrees to two perpendicularly arranged parting planes. To accommodate jaw movement, the maximum included angle at the limb cross-section triangular portion vertex, towards the web, is 90 degrees. The mould cavities are preferably fed through a passage indicated at 30, the injected material dividing into the three streams shown.

Abstract: 1279472 Making filters and silencers HARMO INDUSTRIES Ltd 29 Oct 1970 [30 Oct 1969] 53092/69 Heading B3A [Also in Division F1] Absorbent device comprising a chamber containing a flow tube and having a closely packed fibrous filling in the annular space between the chamber and flow tube is made by closing one end of the chamber and feeding the filling as separate fibres into the opposite end of the chamber. The fibres are packed together and around the tube by reducing the pressure within the flow tube, initially at the end nearest the closed end of the chamber and then over an increasing length of the flow tube corresponding to the increasing level of the fibres fed into the chamber. Apertured tube 23 extends vertically within chamber 20, the lower end of which is closed by flange 22. Piston 25 is an air tight fit in tube 23 which is connected by pipe 2 9 to a suction device. Fibres from hopper 21 fall into annular space 31 and are drawn into a closely packed mass by air flow through the apertures 24. Piston 25 is progressively raised so that it is always at, or slightly above the level of the surface of the fibres. When the chamber has been filled, the tube 23 is removed and replaced by a flow tube which extends beyond both ends of the chamber, that part of the tube within the chamber being apertured. The filling is retained by closing the end of the chamber with a second flange similar to 22, to form a vehicle exhaust silencer. The fibres are separated prior to being fed into hopper 21 by placing them on an endless conveyer which feeds them between a driven helically grooved roller and a counter-rotating spiked roller. The fibres are mineral wool formed from blown slag, or glass fibre. A filter is formed by closing one end of the flow tube so that a fluid passes from the flow tube through the filling into the chamber, which then forms part of the fluid flow path.

Abstract: 1364245 Making dies; abrading E G FELDCAMP 9 Nov 1971 [11 Nov 1970] 53551/70 Headings B3A and B3D An extrusion die or other apertured component is made by making a spark erosion electrode from. a blank by a cutting tool moving in a plane at right angles to the desired electrode axis, forming an aperture in a die blank using the electrode and thereafter forcing an abrasive compound through the aperture. A copper plate is soldered to a steel plate which is mounted on a milling machine table by an electromagnetic chuck, whereupon the copper plate is machined in a single pass to the desired shape by a vertical side milling cutter. The copper plate is removed from the steel plate and the profile finished by hand. The spark-erosion electrode formed is used to make an aperture in a die blank, after which the die is mounted in a holder at one end of a cylinder and a billet of 150 grit silicon carbide particles contained in a plasticised petroleum wax having a penetration hardness not greater than 45, is extruded through the die aperture by a ram. The extruded wax shape is examined to check the shape of the die aperture. An abrasive of liquid or pastelike form may alternatively be used. The die aperture is subsequently polished by hand using an emery cloth, the abrading and polishing steps being repeated using abrasion particles up to 1000 grit size. The die may be heat treated at various stages during the process.

Abstract: 1,166,368. Function generators, analogue to digital converters. WESTERN ELECTRIC CO. Inc. 28 Nov., 1967 [1 Dec., 1966], No. 54028/67. Headings G4G and G4H. In a reflected binary code stage by stage encoder of the kind described in Specification 1,040,614, wherein tandem encoding stages one per digit have analog input, analog output and digit output with V-shaped transfer characteristics between the analog inputs and outputs, the required transfer characteristic is obtained by a circuit wherein the input signal source 22 is connected direct to differential input 2 of operational amplifier 10 and over resistance 30 to inverting input 1 of operational amplifier 11, while amplifier 4 has feedback paths to inverting input 1 (earthed through resistor 20) over forward diode 12 and resistor 13, and reversed diode 15 and resistor 16. Similarly, amplifier 4 having its differential input earthed has feedback paths to inverting input 1 over forward diode 25 and resistor 26, and reversed diode 27 and resistor 28. The junctions of diode 12, resistor 13 and diode 25, resistor 26 are connected to output terminal 46 over resistors 44, 50 while the junctions of diode 15, resistor 16 and diode 27, resistor 28 are connected to output terminal 42 over resistors 40, 51. It is shown that for a linearly variable input current ŒI, a V-shaped variation of output current is produced at terminal 46 and an inverted V-shaped variation at terminal 42 so that the input/output transfer characteristic is also V-shaped.

Abstract: 1,137,200. Time switches. INDUSTRIAL TIMER CORP. 28 Nov., 1967 [7 Dec., 1966], No. 54113/67. Heading H1N. Upon energization a geared synchronous motor (16, Figs. 2 and 3, not shown) drives a cam 18 (via a friction clutch) until lobe 64 engages roller 65 on lever 19 to depress the plunger 35 of a change-over switch 20; a stop 79 on cam 18 then engages a fixed stop 84 at C to stall the cam 18, the clutch slipping until the motor is de-energized. On de-energization of the motor, preferably by operation of switch 20, a spring 85 returns cam 18 to a home position defined by the stop 79 engaging a stop 78 which is adjustable by a knob (17, Figs. 1 and 3, not shown) on the front of the casing, thereby setting the time delay between energization of the motor and actuation of switch 20. A screw 76 in arm 19 provides preset fine adjustment. The range of timing cycles may be changed by changing the motor (16) which is secured by screws (45, Fig. 2, not shown) also securing a lower part (24) of the casing cover in position; this also locks the upper cover part (23) in position with ribs (50, Fig. 13, not shown) thereon engaging the casing main wall (28).

Abstract: 1287901 Liquid scintillation detectors NUCLEAR-CHICAGO CORP 5 Nov 1969 [8 Nov 1968] 54127/69 Heading G1A To compensate for the fact that a pulse height analyzer 50 in a liquid scintillation detecting system has a "dead time period" associated with each analyzed pulse, during which subsequently arriving pulses will not be analyzed, a coincidence and dead time circuit 100 is employed to transmit a dead time signal to timer 71 for each pulse analyzed by the P.H.A. 50 so that the time indicated by the timer as corresponding to a number of analyzed pulses will be the total elapsed time minus the total dead time associated with that number of pulses. As shown, scintillations in a sample 10 are observed by two photo-multipliers 21, 22 and two coincident scintillation events in the sample result in a single output from combining circuit 40, which also produces a single output pulse for each noise pulse generated by either photo-multiplier. The resulting train of pulses from circuit 40 is fed to the P.H.A.50, which usually is one of a number of analyzers each looking at a different portion of the scintillation energy spectrum. Each analyzed pulse from the P.H.A. is fed to a gate circuit 60 and if the pulse is one corresponding to a coincidence event, a coincident signal generated by circuit 100 will simultaneously be fed to the gate circuit so that the pulse passes to a digital or decimal scaler 70. Each pulse analyzed by P.H.A. 50, whether a noise pulse or one corresponding to a coincidence, has a corresponding dead time signal generated by circuit 100 to timer 71. The coincidence and dead time circuit 100 comprises a number of logic elements, Fig.2 (not shown), including an overload detector (103), or coincidence detector (105), and an event detector (104). The overload detector is fed by two amplifiers (101, 102) matched to the amplifier of the P.H.A., and any pulse analyzed by the P.H.A. of sufficient magnitude to overload its amplifier results in the overload detector transmitting to the timer a dead time signal corresponding to the overload time. The event detector generates a dead time signal corresponding to each pulse analyzed by the P.H.A. unless that pulse is an overload one. And the coincidence detector transmits a delayed coincidence pulse to the gate circuit 60 for each pulse analyzed by the P.H.A. corresponding to a coincidence event.

Abstract: 1402527 Automatic adjusters; internal shoedrum brakes GIRLING Ltd 16 Nov 1972 [23 Nov 1971] 54342/71 Heading F2E An internal shoe-drum brake has an adjuster strut comprising male and female screw threaded parts 8, 9 arranged between leading and trailing shoes 2, the part 9 being formed with a ratchet wheel 10 rotatable by a pawl lever 11 to effect extension of the strut 8, 9 to compensate for wear of the brake shoe linings and the pawl tip 12 being formed with two (or more) pawl teeth 12A, 12B spaced apart generally circumferentially of the ratchet wheel 10 along an arc of a circle or on a straight line. As shown in Figs. 1, 3, the shoes 2 may be actuated by a double ended cylinder 5 against the action of shoe return springs 6, or mechanically by an actuating lever 4 pivoted to the trailing shoe 2 at a pivot pin 7 and acting on one end of the adjuster strut 8, 9. Upon service actuation by cylinder 5 the shoes 2 expand to relieve the strut 8, 9 of loading by return springs 6 to allow a spring 13 to pivot the pawl lever 11  so that if the shoe movement is excesive indicating that adjustment is necessary the total movement of the pawl tip 12 is sufficient to effect an increment of adjustment by turning the ratchet wheel 10. Mechanical (hand brake) actuation is effected by rotating lever 4 clockwise to force the tip of the trailing shoe 2 rightwards and the strut 8, 9 and leading shoe 2 leftwards by reaction. The return springs 6 continue to act on the strut parts and rotation of the ratchet wheel 10 is prevented. As seen in Fig. 4, the pawl lever 11 is made as a sheet metal pressing in the form of a bellcrank lever with a hole 17 to receive pivot pin 7. One arm includes pawl tip 12 which is bent at right angles to the remainder of the arm and the opposite arm has a flange 16 for attachment of spring 13 and has a pip 17 which forms a fulcrum point for rocking of the lever 11 about an axis generally parallel with the plane of the lever 11. The pitch of the pawl teeth 12A, 12B is slightly less than that of the ratchet wheel teeth.

A hydraulic or pneumatic motor comprises a piston 2, Fig. 1, continuously supplied with pressure fluid on its smaller effective area side Y and alternately connected to pressure and exhaust on its larger effective area side X, a reversing valve 4 being fluid actuated by a valve 5 responsive to the pressure in the supply line 3, so that when the supply line pressure rises to a predetermined pressure due to piston 2 reaching the end of its stroke or stalling, valve 5 reverses valve 4 to reverse the piston stroke. Valve 5 is adjustably loaded by a spring 34, Fig. 2, with spacers 35, and has an actuating chamber C connected to the supply line 3. In its left-hand position shown, valve 5 connects the actuating chambers A and B of valve 4 to exhaust, a detent mechanism 17 holding valve 4 in position. When piston 2 reaches the end of its stroke or stalls, and the supply line pressure rises above the predetermined value, valve 5 is moved to the right against spring 34, and connects chamber A of valve 4 to the side X of piston 2 and chamber B to the supply line. The effective piston area in chamber A is twice that in chamber B, so that, depending on whether the side X of piston 2 is connected to pressure or exhaust, valve 4 will be moved to the right or left to reverse the connections to motor 1. When piston 2 begins to move on its next stroke, the supply line pressure falls, and spring 34 returns valve 5 to its lefthand position, in which it connects chambers A and B of valve 4 to exhaust.

Abstract: 1,063,560. Heat-treating liquids. SULZER BROTHERS Ltd. Dec. 23, 1965 [Jan. 15, 1965], No. 54673/65. Heading A2D. [Also in Division B8] A heat treatment plant for liquids, such as milk, has means for heating the liquid under pressure by bringing it into contact with steam and then cooling the liquid by pressure reduction, a flow setting device adjustable to a fixed value in the path of the liquid to the steam heating means, a volumetric delivery device downstream of the expansion means, and a sensing element between the expansion means and the volumetric delivery device, the sensing element being arranged to respond to the amount of liquid flowing past it and to deliver a signal to regulate the amount of liquid leaving the delivery device. The liquid for treatment is fed from a storage tank 11 through a float valve 15 to an intermediate tank 13 from which it is pumped by a metering pump 17 through a heat exchanger 23 to a heating system 21 in which live steam is injected into the liquid and thence via a pressure maintaining valve 25<SP>1</SP> into an expansion chamber 25. The pump 17 is driven by a motor 18 which is set to run at one of three speeds according to how many of three package filling machines 50, 51, 52 is in use, the speeds being set so that the pump 17 supplies a quantity of liquid through the plant and thence to a delivery pipe 37 which quantity is about 5% in excess of that required to feed the number of filling machines 50, 51, 52 in use. Liquid accumulating in the bottom of the chamber 25 flows continuously to a centrifugal pump 28 through a chamber 30 of a diaphragm sensing element 31 to a homogenizing metering pump 36 and thence to the filling machines 50, 51, 52. A second chamber 33, separated by a diaphragm 32 from the chamber 30 of the element 31, is supplied with an adjustable pressure through a pipe 34. A change in liquid flow rate through the chamber 30 produces a change in pressure which acts on the diaphragm 32. This activates a rod 38 which adjusts a belt 42 running over conical rollers 40, 41 and thence adjust the speed of the drive from a motor 43 applied to the pump 36. Excess liquid supplied to the pipe 37 is returned via a pressure maintaining valve 54 to the intermediate tank 13. In another embodiment, Fig. 2 (not shown), the pump 36 is run at a rate in excess of the maximum required and a diaphragm sensing element actuates a valve allowing excess liquid to return from the output side of the pump 36 to the sensing element chamber. In a further embodiment, Fig. 3 (not shown), a float level control is used to adjust the belt drive 42 to the pump 36. In yet another embodiment, Fig. 4 (not shown), the two metering pumps are driven by a common variable speed motor, the homogenizing pump having the Fig. 2 embodiment control means.
