Title: Apparatus for sealing cartons
Inventor: CALLABY RONALD KEITH
IPC: B65B7/20
Filed: 1964-07-02
Abstract: 1,075,944. Packaging-machines. MARTINI & ROSSI Ltd. Aug. 5, 1965 [July 2, 1964], No. 27332/64. Heading B8C. An apparatus for closing and sealing closure flaps of cartons c in which the cartons are fed along a conveyer 2, has a frame, a pair of arms 3 at the in-feed side of the apparatus to deflect the flaps open, a pair of rollers 8 to apply adhesive to the flaps, and a pair of arms 13 &c. at the out-feed side to deflect the closure flaps inwards and close and seal the carton. A carton c is fed by the conveyer 2 to a filling station, after which it passes under a spacer pad dispenser (not shown). An operator inserts a pad into the top of the carton and closes its inner closure flaps. Its outer closure flaps are left open and when the carton passes under the arms 3, it trips a switch (7), Fig. 2 (not shown), which activates a pneumatic servo (5) to move a pressure plate (4) down to engage the inner closure flaps. The outer flaps are deflected outwards by the arms 3 as the carton passes through the frame and pass over plates 12 which guide the flaps over spring- urged pressure plates which urge them against the glue rollers 8 driven by a belt (11). The outer flaps are then deflected into the closed position by the anus 13 &c., the inner edges abutting against a central plate 17 which prevents the outer flaps overlapping each other before the carton is sealed. The conveyer 2 then feeds the closed cartons on to lower idle conveyer rollers (21) where upper rollers 19 mounted on flexible arms (20) press the outer flaps on to the inner flaps. The carton rests on the rollers (21) until it is ejected by the next carton. If desired the switch (7) may control the pad dispenser. A photo-electric cell may be arranged adjacent the plate 4 to operate a counting device when the plate 4 moves. A conveyer belt (22) driven by the belt 11 engages the inner top flaps of each carton when it is beneath the glue rollers 8.

Title: Impulse receiver
Inventor: POELMAN ERIK EDUARD PAUL
IPC: H04Q1/442
Filed: 1957-09-02
Abstract: 860,004. Carrier transmission systems. NEDERLANDS, DIRECTEUR-GENERAAL DER POSTERIJEN, TELEGRAFIE EN TELEFONIE. Sept. 2, 1957 [Sept. 3, 1956], No. 27550/57. Class 40 (4). [Also in Group XL (c)] In a circuit arrangement for receiving impulses modulated upon a carrier, which may be one of the carriers of a multi-channel system, the impulses are applied via a wide band-pass filter 4-9 to a first transistor 10, which is normally cut-off by the negative bias applied to its emitter, and which has in its emitter circuit a R.C. network 19, 20 which presents high impedance at the impulse frequency. During an impulse, transistor 10 conducts and operates as a rectifier once the incoming impulse amplitude exceeds the standing bias, and thereafter the condenser 19 is charged, thus increasing the negative bias. The time constant of 19, 20 is of the order of one impulse so that by the end of an impulse the bias has increased to such a value that as soon as the amplitude of the incoming impulse begins to decrease, the transistor 10 is cut off, thus producing an output impulse having a substantially vertical trailing edge. The output from transistor 10 is passed to the voltage doubler rectifier network 11 whence it is applied to a second transistor 12, the emitter current of which operates the impulse repeating relay 13, If desired, the incoming impulses may be limited as at 17, 18 prior to their application to the transistor 10. The transistors may be junction transistors.

Title: Control device for nuclear reactors
IPC: G21C7/16
Filed: 1965-06-30
Abstract: 1,103,878. Controlling reactors. ALLM NNA SVENSKA ELEKTRISKA A.B. 30 June, 1965 [2 July, 1964], No. 27655/65. Heading G6C. A reactor control device comprises a mechanical driving device for moving a vertical control rod, the control rod being fastened to an element which is normally supported within a cylinder by a pressurized fluid and held thus against a part of the mechanical driving device which moves the control rod. When the control rod is to be inserted quickly into the reactor core, it can be freed immediately from the mechanical driving device by reducing the fluid pressure, the rod then falling under its own weight into the core. The element may be in the form of a piston which is held within the cylinder by the pressurized fluid against the driving part of the mechanical driving device, this being for example a nut driven by a rotating screw. Alternatively, the element may seal against a seating which is fixed to the driving part and which separates the space filled with the pressurized fluid from a space at a lower pressure. The element is held against the seating for as long as the pressure below it is sufficiently high. The pressurized fluid can flow between the element and the cylinder wall and the element is so dimensioned in relation to the cylinder that a suitable falling speed is obtained when the element falls freely in the cylinder.

Abstract: 1393035 Measuring device ING C OLIVETTI & C SpA 13 June 1972 [9 July 1971] 27658/72 Heading G1M [Also in Division F2] A measuring device comprises a base 1 having a pair of parallel guides 2, a carriage 3 including a pair of uprights 7 and 8 slidably supported on the guides 2 by aerostatic bearings 14, 15 and 16 and a cross-piece 9, a slider 4 slidably supported on the cross-piece 9 by aerostatic bearings 29, 30, 31 and 32, a feeler supporting arm 5 slidably mounted on the slider 4, and means arranged to automatically adjust the pressure of air supplied to bearings 14, 15, 29 and 30 to correct variations in the set of slider 4 relative to base 1 produced by movement of slider 4 along the cross-piece 9. Carriage 3 is supported on guides 2 by aerostatic bearings 14 and 15, and guided by lateral aerostatic bearings 16, Fig. 2, a set of bearings as shown in Fig. 2, being provided either side of the uprights 7 and 8. Slider 4 is supported at one location by a pair of aerostatic bearings 29 and at another location by a pair of aerostatic bearings 31, Figs. 3 and 4, and is guided along cross-piece 9 by two pairs of aerostatic bearings 30 and 32. Mounted on cross-piece 9 are four rules 51, 52, 53, 54 each provided with a cam surface 55 which adjusts the setting of a respective pressure regulator 61, 62, 63, 64. As shown in Fig. 8, the cam surfaces of rules 51 and 52 are rectilinear and control via the regulators 61 and 62 the pressures applied to bearings 15 and 14 respectively so that the air spacings of bearings 14 and 15 remain equal regardless of the position of the slider 4 along the cross-piece 9, Figs. 9, 10 (not shown). As shown in Fig. 8, the cam surfaces of rules 53 and 54 are curvilinear and control via the pressure regulators 63 and 64 the pressures applied to bearings 29 and 31 respectively to produce air spacings at these bearings which compensate for the elastic deformation of cross-piece 9 caused by the weight of slider 4, Figs. 11-14 (not shown). The arm 5 is of trapezoidal cross-section, Figs. 4 and 6, and is guided in collars 37 and 38 mounted on slider 4. The arm 5 is guided in the collars 37 and 38 by means of air-pressure supplied to channels 41. The weight of the arm 5 is supported by a pneumatic ram 45, Figs. 3 and 8, the pressure supplied to the ram being adjustable by regulator 48. A workpiece to be measured is supported on a rotatable table 6, Figs. 1 and 7. The table is guided laterally by air-pressure supplied to a groove 75 and when it is desired to rotate the table, valve 79, Fig. 8, is opened to admit air-pressure to groove 74 to support the table. A position indicator 73 is provided for the table 6. In use, a feeler mounted on the arm 5 is brought to the desired measuring positions, and the x, y, z co-ordinates are indicated by known measuring and indicating means.

Title: Automatic gas valves
IPC: B64B1/60
Filed: 1920-09-29
Abstract: 152,599. Goodyear Tire & Rubber Co., (Assignees of Maranville, A. G.). Oct. 16, 1919. [Convention date]. Aerostats.-An automatic valve for balloons and air ballonets is held closed by a system of links, two-armed levers, and springs which exerts its greatest pleasure when the valve is closed so that the valve may open fully when the predetermined blow-off pressure is reached. A hub 34 supported by three spider-arms 35 from a ring 11 has rollers 33<a>, 57 for guiding a central spindle 30 secured to a dome-shaped valve 20. The spindle 30 has a stop 30<a> to limit the opening movement of the valve 20, which is additionally stayed to the spindle by a member 32. The valve 20 and ring 11 have flexible gaskets 23<a>, 23<b> normally held just in contact. Pivoted between lugs on the arms 35 are levers 37, the longer arms 37<b> of which are connected by links 43 to lugs 42 on the valve 20, and the shorter arms 37<a> are connected by tension springs 38 to the ends of levers 39 cu toothed quadrants 40 pivoted between lugs 41 on the arms 35. As the valve opens the pull in the links 43 diminishes. The quadrants 40 gear with a screw 55<b> formed on a sleeve 55 which has a gear-wheel 55<a> in mesh with a wheel 54 on a vertical spindle 51. The spindle 51 has forks 49 adapted to be engaged by a member 48 on a spindle 45 when the latter is pushed up against a spring 46 contained in a casing on the valve member 20, so that the initial tension of the springs 38 can be adjusted by turning a knurled head 47 on the spindle 45. An increase of tension in the springs is accompanied by an alteration in the line of action in such a manner as to diminish the rate of decrease of pressure as the valve opens. A guard 80 is screwed to the ring 11. The ring 11 is detachably secured to the envelope as described in Specification 152,600. The member 20 and ring 11 have flexible contacting members 23<a>, 23<b> as described in Specification 152,601.

IPC: G11B3/08
Filed: 1958-08-28
Abstract: 909,856. Gramophones. FOSTER-MALLARD Ltd. Oct. 23, 1959 [Aug. 28, 1958], No. 27680/58. Class 40 (2). A device for controlling automatic stop or record-changing mechanism upon a gramophone comprises a member 28 disposed on a horizontal pivot 27 and carrying a cam follower 29, the member being rocked about pivot 27 in accordance with movement of a bell-crank 39 pivoted at 41 and having the end of one limb engaging a peg 43 on the member 28, the end of the other limb having joins 42 frictionally engaging an extension 23 of a second bell-crank lever 17, pivoted at 18, and which is moved by engagement of a peg 19 with either of the crank arms 17a, 17b; the peg being disposed in fixed relationship with the pick-up arm 14. Outward movement of the pick-up arm causes peg 19 to engage arm 17b and move extension 23, between the joins 23. During playing of a record, stop 19 slowly moves into engagement with arm 17a and thence rotates bell crank 39 thereby rocking the member 28 and moving the cam follower 29 upwardly towards the plane of a cam 13 mounted on the turntable spindle 11; the projecting portion of cam 13 brushes the top of follower 29 each revolution, displacing it downwardly, the frictional grip of joins 42 on extension 23 slipping to permit the resulting motion of crank 39. When the pick-up stylus enters the steep-pitch groove following the playing groove of a record, the follower 29 is moved up rapidly into the plane of cam 13 which thereby engages the edge of the follower and displaces the rocking member 28, together with its support 24; about the pivot 25 disengaging catch 47 from spring-urged lever 44 and thus displacing rod 49 to actuate record changing and gramophone stopping mechanism; this mechanism causing a cam 37 to rotate, the consequent engagement of roller 36 with the curved surface thereof maintaining support 24 and the rod 49 in their displaced positions until completion of the record-changing or stopping cycle; the roller 36 then enters notch 38 in cam 37 to disengage the changing or stopping mechanism. A lever 55 attached to arms 53 and 56 provides manual control of starting, stopping and record changing cycles.

[Class 78 (v)] A fairlead includes two members 19, 13 (Fig. 2) swivelly connected (e.g. 17, 18) on which three sheaves are mounted to engage the rope 14 in the following order: a cross-over sheave 27 mounted in the first member 19; and two sheaves having their axes perpendicular to the swivel axis, one sheave 23 of which is on the first member 19 and a second sheave 29 of which is on the second member 13. As shown, tractor 11 is coupled to trailer 13 ; being pivoted at 22 to connecting piece 21 which is pivoted on axle 20 to member 19, and the latter having a hollow post 18 which turns within the cylinder 17 forming part of the member 13 of the trailer. Control rope 14 for actuating the trailer controls passes under sheave 24, round sheave 27, under sheave 23 (all the sheaves being mounted on member 19), up through hollow post 18, round sheave 29 on member 13 and on to the trailer controls. In the same manner, control rope 15 passes round sheaves 26, 28, 25, 30 and on to the trailer controls. In a modification, sheave 28 may be displaced to the vertical position, so permitting the sheaves 24, 25, 23, 26 to be made co-axial. The object is to allow relative movement between tractor and trailer without actuating the trailer control ropes.
Patent GB-1042149-A (GB)
Title: Polymerization of episulphides
IPC: C08G75/08
Filed: 1962-07-19
Abstract: Polyepisulphides are prepared by polymerizing at least one episulphide which is free from aliphatic unsaturation in the presence of a catalyst comprising a carbonate of a metal of Group IIB of the Periodic Table.  Preferably the catalyst is activated prior to use by heating to an elevated temperature which is below the decomposition temperature of the carbonate. The preferred catalyst is zinc carbonate which may be heated before use, preferably to 140-350 DEG C., particularly 200-300 DEG  C.  Suitable monomers include ethylene, propylene, butylene, phenylene and styrene sulphides.  Polymerization may be effected by the emulsion or solution polymerization techniques, preferably the latter.  The products obtained from propylene sulphide using cadmium carbonate as the catalyst are said to be partially crystalline, whereas those obtained with zinc carbonate are amorphous.  Example I describes a series of experiments in which propylene sulphide is polymerized in the presence of treated and untreated zinc carbonate and, in some cases, in the presence of diethyl ether.  In Example 2 propylene sulphide is polymerized in the presence of zinc carbonate which has been heated to various temperatures.  Example 3 demonstrates the use of a variety of inert solvents for the propylene sulphide/zinc carbonate system. In Example 4 cadmium carbonate is used as a catalyst for propylene sulphide polymerization.

Title: Improvements in and relating to knotting appliances for textile yarns
IPC: B65H69/04
Filed: 1935-10-09
Abstract: 463,446. Knotting-appliances. COOK & CO. MANCHESTER, Ltd., and BROOK, H. I. Oct. 9, 1935, No. 27840. [Class 112] A knot-tying device of the weaver's knot type is adapted to tie reef knots. The device has the usual toothed quadrant 8, thumb trigger 10, return spring, rotary knotting bill 12 provided with cutters 13, and billrotating screw operated by the quadrant. In using the device, the strands to be knotted are laid across the pairs of slots 17 and 18, both being in front of the bill. As the trigger is pressed the knotting-bill turns towards the left and its tip passes behind the nearer strand in the slots 18, at the same time the sliding member 32 and the pivoted arm 41 on the right-hand side begin to cross the strands on that side. As the bill 12 completes one revolution the strands on the left-hand side are crossed by the arms 27, 31 and one strand is looped around the bill. As the quadrant 8 is still further depressed the knotting bill passes downward again between the crossed strands on the left-hand side and as it comes up on the right-hand side, having looped the crossed strand nearer to it, the knotting bill scissors 13 cut the strand. Holding the cut end, the bill turns over to the left. The hook 48 rises and the scissors 49 on it cut the other strand, the hook passing under the strands from the knotting bill to pull the knot tight. The knotted yarn is lifted from the device when the quadrant is released and the crossover arms on the left-hand side return to their original positions.
