Inventor: ROGERS JOHN ANTHONY
IPC: B65B51/20
Filed: 1967-01-11
Abstract: 1,159,497. Carton sealing apparatus. METAL BOX CO. Ltd. 15 Dec., 1967 [11 Jan., 1967], No. 1594/67. Heading B8C. Apparatus for preheating adhesive on carton closure surfaces and then sealing the closure, comprises means to support a carton with adhesive coated sealing areas spaced from each other and to blow hot air into those areas, the support then moving the carton to a sealing position. In one embodiment for closing a filled carton having a hinged lid with front and side closure flaps, Fig. 2, the carton, as shown chain dotted, is fed between guides 20 to abut a detector 21. The latter causes a pusher to forward the carton against a further detector 23, initiating operation of a further pusher 10. The pusher 10 moves the carton on to the support 11, the lid having been previously folded down. During movement on to the support, guides 13 fold the side flaps so that they are finally in close proximity to the outside surfaces of wing portions of a triangular section duct 14. The leading closure flap is folded down to be close to the outside surface of the transverse duct section by means (not shown) and hot air is blown through apertures 15 to melt the adhesive. The support 11 then raises the carton into a close fitting cooled collar 16 which folds down and secures the flaps. The support descends and the next carton it raises ejects the completed one. Alternatively cartons may join a stack passing through vertical guides (not shown). In another embodiment, Figs. 4, 9, for closing flaps at both ends of tubular cartons, the latter are opened out into pockets formed by notches 40, 41 in discs 36, 37 of an intermittently moving turntable. During subsequent movements, all bottom flaps, except the outermost 32, are folded in and at one station 4 a wedge.shaped duct 44 is pivoted by arms 54, 55 and bell crank supports (51), Figs. 5, 6 (not shown), into position between the flap 23 and the underlying flap 30. Hot air is blown via a heater 49 and the duct through apertures 47 to melt the adhesive. During further movement, the flap 32 is folded down and secured and the carton passes to a filling station. It may be vibrated to settle the contents. The top is then closed by means identical with that forming the bottom closure. The carton opening and flap folding devices are conventional and not described. A coding device, also not described, may be provided. The apertures through which hot air is blown may be located to form a seal pattern and may produce a break in the seal to facilitate opening.

Abstract: 770,524. Impregnating fabrics; coated fabrics. FENNER & CO., Ltd., J. H. Jan. 13, 1955 [Jan. 20, 1954; June 2, 1954], Nos. 1661/54 and 16284/54. Drawings to Specification. Class 140. [Also in Group IX] Solid woven power transmission or conveyer belting is made by weaving a multiple ply textile fabric so loosely as to be wholly unsuited for belting duties per se, subjecting it to heat treatment to ensure substantially complete dryness thereof, cooling it and subjecting it to impregnation at atmospheric pressure with a liquid suspension or dispersion of an ungelled polyvinyl compound in a plasticizer, e.g. tricresyl phosphate, and subjecting the impregnated fabric to a heat treatment to gel the polyvinyl compound. The polyvinyl compound may be polyvinyl chloride, or a mixture thereof with a polyvinyl chloride-polyvinylidene chloride copolymer, or any other polyvinyl compound having physical characteristics comparable with polyvinyl chloride, notably as regards ability to pass from liquid dispersion to solid phase without significant volume shrinkage when gelled. Impregnation may be by dipping and the fabric may be squeezed before immersion and squeezed and agitated during immersion in the impregnant. It may be given a sheathing coating by a further passage through a trough of impregnant. Gelling may be effected by passing the belt through a heated tunnel. Examples of suitable weaves for the belt are given (see Group IX).

Title: A liquid cooling and dispensing system
IPC: F25D31/00
Filed: 1952-01-21
Abstract: 707,686. Dispensing liquids. CLEMENTS, C. A. Jan. 21, 1952 [Jan. 20, 1951], No. 1662/52. Classes 106(5) and 116 [Also in Group XIII] A liquid cooling and dispensing system comprises two pistons 12, 16 movable together in cylinders 13, 11, the cylinder 11 forming a measuring chamber for the liquid to be dispensed and the cylinder 13 being filled with oil or other liquid which is displaced to and fro between the cylinder 13 and a refrigerated vessel 21 at each stroke of the pistons. The barrel B of liquid to be dispensed, e.g. beer is contained in a refrigerated chamber D of which the top C forms the counter or bar and is subject to the pressure of CO 2  in a bottle 24. When a valve 27 is opened the beer is forced up a pipe 18 and channel 39, forcing down the piston 16 until an adjustable collar 19 abuts a shoulder 35 at the bottom of the cylinder 11. The air in the space between the pistons is forced through a passage 33 into the refrigerated chamber D and the oil in the cylinder 13 is forced by the smaller piston 12 through a pipe 20 to the bottom of the finned cooling vessel 21, which is also subjected to the pressure of the CO 2  through a pipe 23. The warmed oil rises to the top of the vessel 21 and when the valve 27 is closed and a valve 32 opened the cool oil at the bottom of the vessel 21 is forced back to the cylinder 13, raising the piston 12 to deliver the beer through a spout 31. Cool air from the chamber D is simultaneously drawn through the passage 33 into the space between the pistons. The rod 17 connecting the pistons has a passage 41 to which the oil passes. The valves are controlled in sequence by a single handle. The oil cylinder 13 extends into the refrigerated compartment D and the cylinder 11 is removably connected to the cylinder 13 by bolts 45.

Title: Improvements in or relating to Proportional Servo Systems
Inventor: WATKIN BRIAN LESLIE HIGHFORD
IPC: G01N23/08
Filed: 1968-01-11
Abstract: 1,196,342. Control of A.C. motors. BRITISH PETROLEUM CO. Ltd. 10 Jan., 1969 [11 Jan., 1968], No. 1722/68. Heading H2J. [Also in Division G1] In a proportional servo system, a D.C. error signal is combined with a 12 c.p.s. triangular waveform to produce a carrier waveform which is modulated by a 100 c.p.s. pulse train, the pulse polarity depending upon the instantaneous polarity of the carrier wave. The positive and negative pulses are separated and drive a servo motor in a sense in accordance with the proportion of positive and negative pulses to oppose the error signal. In a two path X-ray absorption analyser for detecting sulphur in oil products, ionization chambers in each path are connected in opposition to a vibrating capacitor electrometer, to produce the D.C. error signal. After addition of the 12 e.p.s. triangular waveform, the error signal is modulated by the 100 c.p.s. pulses in a diode ring modulator. The positive and negative pulses are separated by a transistor connected as a phase splitter with outputs connected to transistors rendered conductive by positive pulses. Servo motor circuit (Fig. 4).-The pulse trains are applied to transistors TR7; TR8 supplying pulses to S.C.R.'s 1 and 2. Conduction of the S.C.R.'s causes pulses of opposite phases to pass through the servo motor, so that the direction of the motor being governed by the proportion of pulses in each pulse train, moves an attenuating wedge to a null balance position in the reference path of the analyser.

Title: Improvements in and relating to apparatus for recognition of character and like electrical signals
IPC: G06V30/10
Filed: 1963-01-15
Abstract: 1,033,532. Automatic character reading. PHILCO CORPORATION. Jan. 15, 1963 [Jan. 15, 1962], No. 1766/63. Heading G4R. In a character reading apparatus the character is first scanned to determine its size and the scanning area is adjusted accordingly. The first scan of the character is made with a scanning area of maximum area by the flying spot of a CRT and the signals are entered into a matrix of serial-connected shift register elements. Elements in rows and groups are connected to Or gates so that any " black " signals on the lines a-u, Fig. 4, give corresponding outputs. The rows u and t are datum lines, the character size being determined at the instant that the character pattern, in its vertical circulation, has a part in row u but not part in row t. The upper extremity of the character is found by examining the upper rows in pairs, detecting when one is covered and the other not. These two rows are grouped with a column at the left-hand side and no output appears from the group until a part of the character is in this column. This ensures that the character is wholly entered in the register before a size signal is given. There are twelve such combinations of two rows and a column corresponding to twelve different sizes of character. The corresponding one of twelve " size " leads is marked. A diode matrix converts this to a combination of signals on four leads 126a-126d, Fig. 12 (not shown), which is entered into storage flip-flops 150a- 150d under the control of gate 152 opened by the appearance of a signal on any of the leads. This is detected by Or gate 160. The outputs of the flip-flops are applied via amplifiers to resistors 168a-168d, weighted 1, 2, 4, 8. The corresponding analogue voltage on line 176 is applied to the collectors of transistors 178a- 178e forming part of another digital-to-analogue converter 30, providing the staircase voltage of the vertical scan control. This includes a binary scale counter 192 counting up to 22 to give 22 steps in each vertical stroke. The transistors 178a-178e are connected to binaryscale weighted resistors 182a-182e and the output passes to the vertical height control of the scanning CRT. A similar circuit adjusts the horizontal width control. The counter 192 may be replaced by a shift register having 24 stages, 22 of which are connected to resistors having successively increasing weightings to produce the staircase voltage. The other two stages give fly-back time.
