Title: Heading machine for forming paper board drums and like containers
Inventor: LEIBREICH NORMAN ANDREW
IPC: B31B17/00
Filed: 1960-12-28
Abstract: 932,725. Making cardboard boxes. MEAD CORPORATION. Dec. 28, 1960, No. 44453/60. Class 18. A machine for closing one end of a tube to form a box or a drum and including a cylindrical former on which the tube is supported and a presser member which inwardly folds and presses an end of the tube downwardly on to a closure disc, is characterised in that the presser member includes an inwardly sloping rim for folding over the end of the tube, the rim being expandable to encircle the tube periphery after the folding, to permit pressing a flat surface against the folded over end while sealing it to the disc. A cardboard tube 8 is placed over an electrically heated former 4 to abut against a stop 5 which is adjustable to allow the machine to deal with different tube lengths. The tube is held in position by inflatable rubber pads 25 mounted on posts 9, 10. A closure disc is inserted, adhesive applied and an assembly 12 carrying the presser member and pivoted at 13 to the post 9 is swung into place above the tube. This movement trips a switch 80 which admits compressed air to the pads 25 and also to a piston and cylinder assembly 38 this causing, through a toggle linkage, the presser member 44 to be moved downwardly on to the upper end of the tube. The inwardly sloping rim 52, Fig. 7, commences to fold inwardly the tube end. This surface is formed on a number of segments 48, Figs. 5, 7, freely slidable in slots 49 and urged by an annular spring 53 into abutting relationship, this allowing them to be forced apart so that the flat underface of the head 44 flattens the tube end against the closure disc. The heated former causes the edge to heat seal to the disc, or if the adhesive is of non heatsealable type causes the adhesive to dry. The former is made hollow and contains an electric fan 34, Fig. 16, which blows air through a hole 33, Fig. 2, to eject the drum.

Filed: 1969-09-16
Abstract: 1277303 Testing integrated circuits GENERAL ELECTRIC CO 16 Sept 1969 45601/69 Heading G1U [Also in Division H1] A circuit, especially an integrated circuit, is tested in a scanning electron microscope operated with unit secondary emission ratio whilst test pulses are applied to the input terminals of the circuit. The microscope shown in Fig.1 is operated with the cathode at -850 volts, the gun enclosure at 6000V, the lens 31 at earth, a pair of screening slats 21 and 22 and the slotted plates 25 and 26 at 3V, and the semi-conductor detectors 18 and 19 at 5-10kV, the beam current being 0.5 microamps and the beam diameter 5 microns. The slats 21 and 22 prevent stray electrons from the scanning beam 11 from striking the detectors, and the plates 25 and 26 restrict the paths of the secondary electrons to which the detectors are responsive. Leads 28 allow test pulses to be applied to the circuit 13, and other leads (not shown) may be provided for supplying operating potentials to the circuit. The outputs of the detectors 18 and 19 are fed through respective amplifiers to a processing unit 37 which adds or subtracts the two signals. Display system, Fig.2 (not shown). A cathode ray display tube is scanned in synchronism with the microscope, the output signals of which are fed as brightness signals to the display tube to provide a static display. In addition synchronizing signals from the scanning waveforms are fed to controllable duration pulse generators which are adapted to produce a start pulse at a line and at a point in the line of the main display selected by the pulse generators; this start pulse initiates the scan of a cathode ray oscilloscope and also causes a test pulse to be applied to the circuit 13. The test pulse is displayed on the oscilloscope alternately with the signal output from the microscope so that the two waveforms appear simultaneously one above the other, and the test pulses may also be superimposed on the static display to indicate the area being monitored by the oscilloscope.

Title: Document Abstractor
IPC: H04N1/107
Filed: 1968-09-26
Abstract: 1,196,386. Facsimile recording. XEROX CORP. 26 Sept., 1968 [29 Sept., 1967], No. 45824/68. Heading H4F. The Specification describes a portable facsimile apparatus, Fig. 1, comprising a light scanning assembly 2 which is moved manually across the information 4 to be recorded, a processing circuit assembly 6 and a reproducing assembly comprising a modulated light source reproducing head 10 carried by a lead screw 14 over the recording medium, and a motor 8 turning said lead screw. The scanning means in both the assembly 2 and the head 10 carry out a cyclic scan at right angles to the line of movement of the assembly and head, i.e. where the assembly is moved along a line of print, the scan is across said line (Fig. 6). The invention is concerned with causing the reproducing head 10 to follow changes in the rate of manual movement of the assembly 2 and for corresponding changes in the rate of scan within the assembly and head such that lines of scan in Fig. 6 are always equally spaced. The assembly 2 comprises, Figs. 2, 3 and 4, a casing formed with a handle portion 20 and a foot portion 38 carrying pairs of rollers 40/42 joined by tracks 48. The assembly is thus rolled over the information 4. A light source 28 projects a beam on to an oscillating mirror 24, the oscillation being at right angles to the plane of the drawing and being caused by the mirror being mounted on the end of a piezo-electric element 22 which is caused to flux by applied electric pulses. The beam is projected on to the information with the required scanning movement. The light reflected from the information is detected by photo-electric means 36. A spoked wheel 54 is fitted on the shaft 46 of rollers 42 and the spokes thereof periodically interrupt the light passing from a source 56 to a detector 58, the detector thus produces a pulsed waveform having a repetition frequency proportional to the speed of the manual scan.. The output of detector 58 is fed to a pulse generator 68 in assembly 6 to produce a corresponding train of pulses These pulses are fed to the two scan means in the assembly 2 and the head 10, whereby each pulse causes one scan line. The train of pulses is also integrated at 72 to produce a signal proportional to the speed of the manual scan and said signal is used to energize motor 8 and control the speed thereof.
