IPC: B65B9/12
Filed: 1968-04-02
Abstract: 1,228,901. Packaging machine. SELFPACK VERPACKUNGS - UND VERTRIEBS G.m.b.H. 2 April, 1968 [5 March, 1968], No. 15838/68. Heading B8C. In a form-and-fill machine making squaredup liquid filled containers, the liquid supplied to the container being formed is adjustably throttled to avoid over-pressurizing as each container section is shaped. Throttling is obtained by restricting the liquid filled tube above the transverse welding dies. A web 3, Fig. 2, of pliable material e.g. coated paper filled with liquid 7 is fed between rollers mounted on supports 8, 9 and sealing dies 1, 2. The bottom rollers 10, 11 are separated by an adjustable gap 12 which restricts the quantity of liquid entering the tube below the dies as it is drawn downwardly between shaping plates 19, 20. Further shaping plates 21 at right angles to the plates 19, 20 move from the inactive position of Fig. 5 to the active position of Fig. 6. Two plates 22, coupled to plates 21 and each positioned, and offset at opposite sides of the plates 19, 20, rise to support and shape the bottom of the container 6 leaving a gap 24 to allow the seam 23 to protrude as shown. After filling, the dies 1, 2 move together and ribs 25 formed on their bases permit bulging to relieve excess pressure during sealing. The gap 12 can be adjusted by a spindle and nut device 16, 18 which pivots the support 9 about an axis 15. In a modification, Figs. 3, 4, not shown, the spindle and nut device is attached to the die 1. As the dies open the rollers (11<SP>1</SP>) are moved towards rollers (10<SP>1</SP>) to reduce the gap and the flow of liquid as the web is drawn downwardly. As the dies move together the rollers separate.

Abstract: 1,230,126. Centrifugal blowers. KUHNLE KOPP AND KAUSCH A. G. July 17, 1968, [Aug.21, 1967], No.34041/68. Heading F1C. In order to permit relative thermal expansion and deformation between the inlet pipe 16, Fig.3, of the housing of a radial-flow blower and the remainder 18 of the blower housing without consequent binding of the seal 28, the inlet pipe 16 is constructed and mounted separately from the remainder of the housing, and an elastically or plastically deformable member 88 forms a gas-tight connection between the two housing parts 16, 18. In an alternative embodiment, Fig. 5 (not shown), the impeller has no rotary front shroud but is instead associated with a stationary front shroud (100) which is carried by the inlet pipe 16 and closely surrounds, to form a cylindrical sealing gap therewith, a cylindrical section (106) arranged on the impeller adjacent the inlet ends of the impeller blades. The impeller shaft 4 is supported in a stepped bearing 6 and a bearing 8 which allow the shaft to expand only leftwards to avoid reduction in the efficiency of seal 28. The housing part 18 is supported on two horizontal-expansion-permitting guides formed by members, e.g. as at 34, extending laterally from one side wall of the housing part 18 and co-operating with bearing blocks, e.g. as at 38. Additional horizontal-expansion-permitting guides may be disposed at the other side wall. Moreover, the housing part 18 is guided by a vertical-expansion-permitting guide formed by members 40, 42, 44. The inlet pipe 16 is supported on two horizontal-expansion-permitting guides (66, 68), Fig. 1 (not shown), and a vertical-expansionpermitting guide 70, 72, 74. A portion 20 of the inlet pipe 16 may contain fixed guide vanes. A cooling disc 90 may be arranged at one or both ends of the blower housing.

Abstract: 1,258,598. Pulse modulation circuits; facsimile systems; transistor gating circuits; automatic gain control. XEROX CORP. 30 June, 1969 [1 July, 1968], No. 32898/69. Headings H3R, H3T, H4F, H4L and H4R. In a chopper circuit a signal of varying amplitude is supplied to the input of an amplifier, pulses of predetermined duration and frequency are coupled to the input of the amplifier alternately to enable and disable the amplifier, whereby the amplifier provides pulses whose amplitude varies in direct relation to the amplitude of the said signal and means coupled to the output of the amplifier generate a voltage to control the gain of the amplifier. General description.-An optical scanner 10 scans a document 14 and the resulting signal from a photo-cell 16 is supplied to a differential amplifier 22 having an electronic chopper circuit 18 connected across its two inputs. The amplitude-modulated output pulses of the amplifier 22 are supplied via a buffer amplifier 24 to an output circuit and the output of amplifier 24 is also demodulated at 26 and fed to a peak detector 20. The detector 20 provides a voltage dependent upon whether the background of the document 14 is all white or is darker so that if it is darker the gain of amplifier 22 is increased accordingly. Circuit details.-A photo-cell V1 provides a signal related to the document being scanned, a further photo-cell V2, not exposed to light, providing temperature compensation. The outputs of the photo-cells are supplied to the two inputs of the differential amplifier Q3, Q4, respectively and a chopper comprising a dual emitter transistor Q7 controlled by clock pulses is connected across the inputs, the output of the differential amplifier being taken via buffer amplifier Q1, Q2. The differential amplifier balances out unwanted transients generated by the internal capacitance of the transistor Q7. The parallel combination of resistors R2, R8 determines the output impedance of amplifier Q3, Q4 and a field effect transistor Q5 is connected across R8 to vary this output impedance and hence the amplifier gain by a control voltage derived as in Fig. 1 and supplied via transistor Q6. The buffer amplifier includes a field effect transistor Q presenting a high impedance to the differential amplifier.
