IPC: B65C9/36
Filed: 1964-10-03
Abstract: 1,063,595. Bottle labelling machines. MORGAN FAIREST Ltd. Oct. 4, 1965 [Oct. 3, 1964], No. 40371/64. Heading B8F. In a machine for applying sealing and body labels to wine stoppered bottles the bottles 1 fed by a conveyer 2 are spaced by a worm 3 and indexed to the correct position about their vertical axis while on a star wheel 5, as described in Specification 1,056,035, on their way to a table 10 on which they are held by presser heads for passage through labelling and wiping stations before return via a star wheel 14 to the conveyer 2. Sealing and body labels are extracted from stocks 18, 19 respectively by common switch transfer means 21 which transfers the sealing label to applying means 27 comprising sets of arms rotatable about a vertical axis and controlled for indexed movement by spring means co-operating with a cam or V notches so that a label is held by suction at the top and bottom by two of the arms, with the gummed face opposite the advancing bottle. As the bottle advances it engages the sealing label and rotates the arms so that they are moved by the bottle to the next indexed position, thus wiping on the label and positioning the next arms and label in the path of the next bottle. The body labels are transferred to suction wiper plates 46 pivoted separately on fixed parts of the machine and between which the bottles pass for application thereof. The labels are then wiped on by wiper brushes 12. In a modification the labels are wiped on after application by pressing means mounted on arms rotatable on vertical axes and between which the bottles pass rotating the arms to bring the next arms into aligned position for the next bottle.

Title: Surface potential analysis by electron beams
IPC: H01J49/48
Filed: 1968-08-24
Abstract: 1286454 Local viewing CAMBRIDGE SCIENTIFIC INSTRUMENTS Ltd and C W OATLEY 24 Aug 1969 [24 Aug 1968] 40560/68 Heading H4F [Also in Division H1] A method of analysing the electric potential on a specimen surface S comprises causing an electron beam to impinge on the surface, detecting the resultant back scattered and/or secondary electrons by a detector D (e.g. scintillator with photo-multiplier), or detecting the resultant specimen current and switching between two levels either the potential applied to the surface or the potential level of a potential barrier in the path of the electrons passing to the detector, when present (Fig. 3, not shown), the resultant signals at the two levels being directed respectively into one of two channels and a final signal corresponding to the difference obtained. The signals are preferably directed into the alternate channels in synchronism with the switching. The method indicates potential distribution which may also be representative of other phenomena, the difference measurement eliminating topographical or secondary coefficient variations to a first order. In Fig. 1, gate G1 controlled by square wave generator G1 is between voltage source P and specimen S, being at 100 KHz within a 30 lines/sec. scan, generator SG switching gate G2 synchronously to direct detector D signals alternately to channels C1 and C2, the signals being demodulated and compared in differential amplifier DA and fed to a C.R.T. or X-Y recorder. The former C.R.T. beam may scan synchronously to produce a two-dimensional contrast image. The primary beam is switched at twice the specimen switching frequency and may be on for only a portion of each interval via frequency doubler F and pulse width control W to gate G3 to ensure equilibrium is established at each cycle on the specimen surface. Gate G3 may be replaced by deflecting plates. In Fig. 3 (not shown), particularly for specimens with static contact potentials, grid 4 is switched between two low potential levels preferably adjustable in amplitude and mean level, e.g. 0 to - 5 volts. Specimen potential may be 250 v. and second grid H<SP>1</SP> accelerates secondary electrons and shields surface S from grid H. The specimen may be normally orientated but the Fig. 3 arrangement ensures the scintillator is less affected by high energy reflected electrons.

Filed: 1971-09-08
Abstract: 1361678 Detail boundary detection ITEK CORP 8 Sept 1971 [14 Sept 1970] 41864/71 Heading H4F A scanning system for detecting boundaries in, for example, photographic transparencies, and which is adapted to detect such boundaries whatever their orientation with respect to the scan direction, utilizes signals produced from sub-areas of the scanning spot and analyses these signals or their differences. In a first embodiment the pick-up head for the transmitted light from a transparency comprises four light detectors arranged at the corners of a square, their outputs being fed to logarithmic amplifiers and the resultant signals being passed in (opposite) pairs to two subtractors producing vertical and horizontal gradient values. These values are squared before adding so that the resultant output is always positive and when it exceeds a given threshold actuates a line-drawing mechanism such as a C.R.T. or facsimile printer, operating in synchronism with scanning means moving the transparency. In a second embodiment the light spot scanning the transparency is given a circular "wobble" by means of a tilted and rotated glass plate through which the light beam passes. When a brightness boundary is reached, the output from a detector receiving the transmitted light will have a variation at a frequency equal to the rotational frequency of the tilted plate. This frequency is filtered out and if exceeding a certain amplitude threshold used to control line drawing. In a modification the scanning spot may be obtained from a C.R.T. tube and "wobble" voltages superimposed on the raster deflection voltages applied to the scanning coils, and in another the scanning may be effected by imaging the transparency on the cathode of an image dissector tube and using as scan signals for the tube a combination of raster and wobble signals. Phase comparison of the output signal component at wobble frequency with the wobble signal itself enables determination of the direction of boundary lines.

A demodulator for phase-shift telegraphy comprises two phase-sensitive detectors 10 and 11 fed with the input signal from terminal 12, the detector 11 being supplied with a reference signal from a local oscillator 13 via a 90 degree phase-shifter 18, and the second detector 10 being supplied with the local oscillator signal through a balanced modulator 19 supplied with the filtered output of the first detector 11 and providing an output signal which is filtered and used to control the phase of the oscillator 13. It is shown that the signal f<SP>1</SP> 1 (t) providing the output at terminal 21 is proportional to sin [(# 1  - # 0 ) t+(# 1  - # 0 )] and that the signal f 3 (t) controlling the oscillator 13 is proportional to sin [2(# 1  - # 0 ) t + 2(# 1  - # 0 )], i.e. has twice the frequency and phase difference of the original signals. Improved phase lock-on may be obtained by increasing the gain of amplifier 20, and, if desired, limiting its output, so that the system is non-linear. In a modification, Fig. 2 (not shown), the phase shift network 18 is disposed between input terminal 12 and detector 11.
