Abstract: 1,054,989. Photo-electric thickness measurement. INDUSTRIAL NUCLEONICS CORPORATION. Sept.17, 1964 [Sept. 18, 1963], No. 38062/64. Heading G1A. In a method of producing a double sheet of plastics material by blowing a bubble of plastics film 20 from a rotating circular die 17 and then flattening the bubble between rollers 25 the thickness of the double sheet is measured by a radiation gauge 28-30 situated at the edge of the sheet so that thickness at points along the length of the sheet can be correlated with single holes in the circular die. The gauge is maintained on the edge of the sheet by an edge follower. Fig. 3 shows a circuit to provide a record and also an average value of the thickness over one revolution of the die. Potentiometer 72 is coupled to a measuring servo which gives an output of sheet thickness; potentiometer 75 is set according to the desired thickness, and by means of the chopper 100 coupled to these potentiometers a recorder potentiometer 77 is driven according to the difference between the measured and desired thicknesses which drives the recording chart 84. With the contacts 90a, 90c and 90d closed the integrator obtains an average value of the variation in thickness whilst they are being recorded. After a predetermined time, the above contacts open and 9c and 90f close to connect the integrator voltage into the recording bridge to record the obtained average value on the chart. The integrator is then reset to begin the cycle again. A circular chart may be provided showing die-hole positions and thickness measurements at points along the sheet correlated to particular holes.

Abstract: 1,237,916. Fluid metering device. K. ARTMANN. 17 July, 1968 [18 July, 1967; 21 Dec., 1967; 29 April, 1968], No. 33942/68. Heading B8N. A device for dispensing a metered quantity of fluid, e.g. beer or lemonade, comprises a metering chamber 9, a metering piston 10 in the chamber, and a control member movable to a first position to permit fluid to flow into the chamber 9. A locking member 32 is engageable with the control member to retain it in its first position during the flow of a predetermined quantity of fluid into the chamber 9. The piston 10 is moved as fluid enters the chamber 9 so that when the predetermined quantity of fluid has entered the chamber the piston moves the locking member to release it from the control member to permit the control member to move to a position in which further fluid is prevented from entering the chamber 9. The movements of the control member and locking member are along mutually perpendicular rectilinear paths. In one embodiment the control member is a piston 22 slidable within a housing 1. When the piston 22 is moved into said first position by operation of a push-button 24 it closes discharge ports 64 and opens inlet valve 12, thus allowing fluid to flow via connecting duct 8 into the metering chamber 9 where it raises the piston 10 against the action of a spring 37. The piston 22 is held in its first position by engagement of a locking member in the form of a spring-loaded rod 32 in a recess 26 thereof until a predetermined quantity of fluid has entered the chamber 9. At this stage the piston 10 engages a collar 66 on the rod 32 to raise the latter and allow the piston 22 to move to a second position in which the valve 12 is closed and the discharge ports 64 are open. Fluid is thus discharged from the chamber 9 via duct 8 and ports 64 as the piston 10 advances under the action of spring 37. In its uppermost position the piston 10 may engage a tappet 61 to operate a counter 57. The collar 66 is adjustable on the rod 32 to vary the amount of fluid dispensed. In a second embodiment, hydraulic damping means are provided for the piston 10 and the discharge outlet is in direct communication with the free space in the housing 1 between the piston 22 and valve 12. In this case the discharge outlet is provided with a control member for adjusting the discharge velocity. In a further embodiment, in which counting mechanism is provided the piston 22 is provided with a pair of recesses 26 in succession positioned to ensure that the device cannot be used to dispense fluid without operating the counting mechanism. In any embodiment the chamber 9 may be enclosed in a cooling jacket. Instead of adjusting the quantity dispensed by means of the collar 66, a sleeve of a predetermined length and slidable along the rod 32 may be positioned above the piston 10 to be raised with said piston to engage the collar 66. In this embodiment an extension rod of the same length as the sleeve is attached to the tappet 61 of the counter 57.

Abstract: 1,239,230. Balling yarns. S. M. WHEELOCK. 13 Sept., 1968, No. 43583/68. Heading D1J. Balls of filamentary material are wound on rotating vertical spindles 17, Fig. 1, by vertically reciprocating yarn guides 45. When the packages are complete they are caused to slide down the spindles 17 by means of bushings 35 actuated by doffing rods 33. The doffing rods 33, Fig. 8, carry bars 37, 38 that slidingly engage in an annular groove 36 in the bushings 35. As each package and its associated yarn guide 45 moves down a spindle 17, further guides 44a, 44b cause the bar 38, and therewith the yarn guide 45, see Fig. 8, to move transversely of the spindle 17 to a setting in which a centre wrap 46, Fig. 2, of filamentary material is wrapped around each ball. Thereafter the guides 45 are raised to their initial settings and the sequence of operations is repeated, the initially wound balls of material being eventually forced off the spindles 17. As the balls leave the spindles a heated wire 56 is moved to a setting in which it burns through the material interconnecting the doffed balls with balls still on the spindles 17.

Abstract: 1,251,339. D.C. to A.C. static invertors. DANFOSS A.S. 29 Aug., 1968 [29 Aug., 1967], No. 40132/68. Heading H2F. In a firing pulse producing arrangement for a D.C./A.C. invertor, it is arranged that firing pulses for load thyristors are delayed with respect to firing pulses for commutating thyristors which are connected in series with commutating capacitors, to ensure that the capacitors are always charged in readiness for subsequently turning off their respective load thyristor. The invertor circuit illustrated in Fig. 3 (not shown) is the same as that described and abridged in respect of Specification 1,250,195. Briefly, it includes two load thyristors which are fired alternately to supply, via a centre tapped choke, a full wave square waveform to an output, and in parallel with each load thyristor there is a separate commutating circuit including a capacitor and thyristor in series, the latter thyristor being fired firstly to effect charging of the capacitor and secondly to effect discharge thereof to turn-off the load thyristor. Pulse circuit (Fig. 4).-An h.f. signal e, an l.f. signal T and a signal W derived from the invertor output are fed into the circuit and are added by a network R15, R13 and R32. Their sum is applied to a zero level or null detector comprising a differential amplifier Tr14, Tr15, the base of Tr15 being connected to zero potential. The detector is connected to an output amplifier Tr7, Tr8, at an output point 2 of which a square waveform signal b is produced, and at an output point 3 a square wave signal b<SP>1</SP> in phase opposition thereto. The waveform b (see Fig. 2) is differentiated by C15 and the resulting signal i 1  is fed to an output terminal 1W via a pulse forming stage comprising Tr9 and a transformer T2. The waveform b<SP>1</SP> is differentiated by C14 to produce pulse signal i 2  which is fed to output terminal 3W via Tr6 and a transformer Tl. The pulses at 1W and 3W are to fire the commutating or quenching thyristors. Signals b, b<SP>1</SP> are also applied to the inputs of a differential amplifier Tr11, Tr12 and the two outputs thereof are differentiated by C16, C17 respectively and are transmitted as firing pulses Z 1 Z 2  for the load thyristors to terminals 2W, 4W, via Tr10 and transformer T3 and via Trl3 and transformer T4 respectively. A Zener diode EZ3 determines the minimum operating voltage, for Tr11 and Tr12. The striking pulses Z 1 Z 2  for the load rectifiers follow respectively the quenching rectifiers firing pulses i 1 i 2  after a short interval but with a slight overlap (Fig. 2). The desired delay is obtained solely due to the fact that the rise times of square wave voltages bb 1  across the null detector are lengthened by the differentiating elements C14, C15 for the load rectifiers firing pulses.

Abstract: 1,257,898. Labelling machines. H. KRONSEDER. 6 July, 1970 [7 July, 1969], No. 32554/70. Heading B8F. In a labelling machine having labels 4a transferred from a container 5 to a labelling cylinder 1 by a suction roller 3, the container is given a circulatory motion and the suction roller is rotated at a cyclically varying speed such that it performs substantially rolling motions over the adjacent faces of the container and labelling cylinder, and has a reduced speed at the initiation of the take-up of a label which is less than the speed of the container in the same direction so that the leading label is withdrawn from under retaining nibs at the forward end of the container. The suction roller 3 is fast with a shaft 28 eccentric to a driving shaft 23 and having a crank pin 13 engaging a diametral slot in a disc 10 fast with the driving shaft. The label container 5 is fast with a carrier 9 which is pivoted at 29 to a link 16 which in turn is pivoted at 30 to the machine frame. The driving shaft 23 is geared to a shaft 20 having an eccentric 21 coupled to an element 6 slidably mounted on carriage bars of the carrier 9 and urged rearwardly by springs 7 reacting against a stop 8. The container is thus given a circulating movement, and in its forward position, in which a label is extracted by the suction roller 3, the roller is rotated at its slowest speed. After 180 degrees rotation the roller 3 is rotating at its greatest speed, equal to that of the labelling cylinder 1, to which it transfers the label. In the absence of bottles to be labelled, a switch is actuated, controlling an electromagnet which pivots a blocking member 24 to engage a radial arm 31 on the pivot shaft 30 of the link 16 to retain it in its rearmost position. Thus labels can no longer be extracted from the container by the suction roller. If bottles are again supplied to the machine, the electromagnet removes the blocking member 24.
