Title: Packing of cigarettes or other rod-like articles
IPC: B65B19/04
Filed: 1975-02-17
Abstract: 1497221 Cigarette packaging machines; variable capacity article magazine in conveyer system FOCKE & PFUHL 17 Feb 1975 [16 Feb 1974] 6681/75 Headings B8C and B8A In a cigarette making and packing apparatus in which cigarettes are formed into groups 15 and each group is wrapped in a first blank, usually of metal foil, an intermediate paper blank or hard-top pack, and an outer blank of regenerated cellulose film, a buffer store 20 for the groups wrapped in the first blanks is provided between the first and subsequent wrapping stations to accommodate variations or interruptions in the flow of groups 15 through successive wrapping stations. The buffer store 20 comprises an endless conveyer 31 which carries groups 15 wrapped in metal foil from the first wrapping station 16 to the second wrapping station 18, the conveyer having at least one variable length loop 43, Fig. 2, with a compensating variable length loop 51 in the return section. The pulley 44 of loop 43 is movable by a motor 54 acting via a leadscrew 55 and a nut 56. If the apparatus fails upstream of the store 20, a pulley 40 stops, and motor 54 is run to steadily reduce the length of loop 43 to maintain the supply of groups 15 downstream. If a failure occurs downstream of the store, a pulley 45 stops, and motor 54 is run to increase the length of loop 43 to absorb the output from station 16. The conveyer 31 comprises chains 31a, 31b interconnected by cross-pieces 32 each with a projecting pocket 33 formed by three walls 34-36, with an aperture (37) (Fig. 4, not shown) in the cross-piece aligned with the pocket. A conveyer 11 carries cigarettes produced by a rod machine 10 to a magazine 12 from which groups 15 are passed to a test turret 13. A conveyer 14 carries tested groups 15 to the first wrapping station 16, where a pusher 23 pushes each group 15 through the plane of a metal foil web 24 into a pocket 22 of a step-rotated turret 21, to form a U-fold of foil round the group. Tappet folders 25, an oscillating folder 26, and a fixed folding guide 27 complete the edge folding. A reciprocating rod 29 pushes the group 15 past fixed end-folding junctions 30 into a pocket 38 of an oscillating arm 39. As this accelerates to the conveyer 31 speed, a pusher 41 on the arm transfers the group 15 into a pocket 33 of the conveyer 31, Fig. 3. At the station 18, a pusher 49 on an oscillating arm 48 transfers the group 15 from its pocket 33 into a paper blank or hard-top pack 47 in a pocket of a turret 46, from whence it passes to a station 19 for wrapping in cellulose film. In a modification, Fig. 5, the conveyer 31 includes a sag 61 adjacent the station 16 so that the pulley 60 can be driven intermittently in time with the turret 21, while the remainder of the conveyer can move continuously. The buffer store loop 62 and compensating loop 63 are parallel, with their movable pulleys 64, 65 carried by a common block 66.

Title: Improvements in or relating to photographic estimating and calculating device
IPC: G01J1/12
Filed: 1942-05-19
Abstract: 557,492. Photographic density and printing meters. KODAK, Ltd. May 19, 1942, No. 6815. Convention date, Aug. 15, 1941. [Classes 98 (i) and 98 (ii)] A device for estimating the gray scale densities or negatives of subjects which are photographed together with a gray scale comprises a body portion adapted to receive the negative with a preselected step of the scale showing through a slot in the body, and a density gray comparison scale which is slidable in the body to bring apart thereof into matching relation with the preselected part of the negative gray scale and is provided with a scale of density values which permits the density of said pre-selected part to be read off through an aperture in the body. The device may also incorporate a slide calculator for determining the relative printing exposure times of a set of colour-record negatives, each bearing a gray scale, when the density range of each negative has been estimated on the device and the correct printing exposure for one of them is known. The device shown has a body 12 as of laminated cardboard having a flap 27 under which a negative 28 may be tucked so that its gray scale 29 rests adjacent to a density gray scale 18 on a strip 20 slidable in a slot 16 formed internally in the body, said strip also carrying a scale 21 of corresponding density values. The negative 28 may be so placed that any selected step of its gray scale appears through a window 23 in the flap 27, and this window is wide enough to include also a step of the gray scale 18, so that by sliding the strip 20, a step of the scale 18 matching the selected step of the negative gray scale may be brought into the window ; the density value of this step is then indicated in a window 24 formed in the body 12 above the density-value scale 21. For determining the relative printing exposure times of a set of colour-record negatives, each negative is placed in turn in the device and the density values of two spaced steps of its gray scale, usually the highest and lowest, are determined ; by subtraction of these values, the density range of each negative is obtained. The printing exposure time of one negative is determined by trial or estimated by experience, and from these data the relative exposure times are found by means of a calculator provided on the back of the device as follows. The back 17 of the strip 20 carries a scale 33 of relative exposure times showing through a slit 31 in the back of the body 12, and at the side of this slit is a fixed scale of density values 34. If, for example, one of the negatives is known to have an exposure time of 30 seconds, and its density range has been found as described above to be 1.5, the strip 20 is adjusted in its slot until the exposure number 30 on the scale 33 rests opposite the density value 1.5 on the scale 34. The exposure times for each of the other negatives can then be read off on the scale 33 opposite its density range on the scale 34.

Title: Flow control system for load-handling apparatus
Inventor: OLSON JOHN ELMER
IPC: B66C19/00
Filed: 1962-02-22
Abstract: 998,314. Lift trucks. HYSTER CO. Feb. 22, 1962, No. 6924/62. Heading B8H. In an hydraulic system comprising two or more rams which are supplied with fluid from a common source, such as an hydraulic system for a fork lift truck provided with a pair of masttilting rams or for a straddle carrier provided with four rams for raising a pair of load supports, check valves are provided prohibiting fluid flow between the cylinders after the positions of their pistons has been set but permitting either set of ends of the cylinders to be supplied with fluid under pressure and the cylinders to be connected together for the supply of fluid from a common source. As shown in Fig. 2, when the spool of a directional control valve 43 is moved to the right to tilt the mast 13 of a lift truck forwardly, fluid passes from the pump 45, through the line 53 to the righthand side of the cylinders 15, 17 of the tilt rams and through lines 53, 68 to the spool of a valve 61 which is thereby moved to the left against the action of a spring 67 thereby connecting lines 63, 65 from the left-hand side of cylinders 15, 17 to the line 55 from the reservoir 49. If the mast tends to tilt forwardly under its own load, the pressure at the right-hand side of cylinders 15, 17 will drop and the spool of valve 61 will be moved back by the spring 67 to the position shown, thereby breaking the connection between the lines 63, 65 from the cylinders. The mast is tilted back by moving the spool of valve 43 to the right so that fluid from the pump passes through the line 55 and ball valves 83, 79 to the left-hand side of cylinders 15, 17. If, when the spool of valve 43 is centred, the mast 13 tends to twist as the truck goes round a corner, the ball valves 83, 79 prevent flow of fluid between the cylinders and therefore prevent the mast from twisting. A similar circuit, Figs. 3, 4 (not shown), is applied to four rams supporting a pair of load supports of a straddle carrier, wherein the load supports are maintained at the same level in the event of uneven loading.

Abstract: 779,447. Type-making machines. TELETYPESETTER CORPORATION. March 6, 1956 [June 30, 1955], No. 6996/56. Class 100(3) Strip-perforating machines. In a keyboard-operated tape-perforating apparatus in which selected punches of a tape-perforating device for producing code combinations of perforations in a second tape such as may be used for automatically controlling the operation of a type linecasting and composing machine are actuated by means of a cam through a clutch comprising a driving member 85 which is controlled by a blocking lever 16 as described in Specification 778,570, the lever 16 is held in engagement with the member 85 by a spring 18, and the clutch tripoff member 36 when actuated by any of the keys 14 is adapted to close a contact for energizing an electromagnet 19 to release the member 85, the lever 16 serving as the armature of the magnet. A D.C. or rectified A.C. source of current charges a capacitor 27. When the trip-off member 36, which is a universal bar, closes contacts 32, 31, the capacitor 27 charges a capacitor 34 through the electromagnet 19, thereby energizing the latter until the capacitors 27, 34 approach equilibrium when the current becomes insufficient and the lever 16 is released. On release of the member 36, the contacts 32, 31 are opened and contacts 32, 33 closed to discharge the capacitor 34 through a resistor 28. The released lever 16 then engages the other of two extensions 82, 83 of the member 85 to stop the latter. If a repeat key 38 is depressed, it acts after the member 36 is actuated by a key to establish a holding circuit for the magnet 19 through a resistor 39, the current being insufficient to actuate the lever 16 prior to the closing of the contacts 32, 31. The device may be actuated by remote control as indicated in interrupted lines, the capacitor 34 and resistor 28 being replaced by a capacitor 62 and resistor 63 and the contacts 31, 32, 33 by a contact assembly 61 including a remote control lever 64. Specification 420,084 also is referred to.

Title: Apparatus for spark machining
Inventor: LINES ANTHONY HILLESDEN
IPC: B23H1/04
Filed: 1954-03-11
Abstract: 762,212. Cutting by spark discharge. NAPIER & SON, Ltd., D. Feb. 16, 1955 [March 11, 1954], No. 7142/54. Class 83 (4). In a spark-erosion apparatus, the tool electrode is made of a composite material consisting of a matrix of a metal of good electrical conductivity in which is carried and dispersed in the form of minute particles or granules, graphite or other non-metallic substance or metallic carbides, having a higher melting-point than that of the matrix metal. The latter may be silver or preferably copper and the graphite is preferably colloidal graphite. The electrode may comprise 84 per cent copper and 16 per cent colloidal graphite or 65 per cent copper and 35 per cent colloidal graphite. Alternatively the high-melting substance may be boron carbide. During the erosion, especially of hard metals such as alloy steel, the sparking surface of the electrode presents a series of high points formed by the high melting point substance pro'ecting very slightly above the surrounding matrix metal whereby these high points tend to take the main brunt of the discharge and thus tend to equalize the rate of wear of the electrode to that of the workpiece. The electrode and workpiece are preferably immersed in a liquid, for example paraffin, during erosion. The apparatus is of use in forming holes or recesses of particular cross-section and the electrode may be fed automatically towards the work-piece by apparatus responsive to the mean electrical potential between the electrode and workpiece. When the electrode is made of 84 per cent copper and 16 per cent graphite, the working end thereof may be re-shaped by pressing in a die.

Title: Improvements in or relating to the manufacture of impregnated paper sheets
IPC: D21J1/16
Filed: 1941-06-06
Abstract: 550,562. Treating materials with liquids. MUNTERS' INDUSTRI AKTIEBOLAG. June 6, 1941, No. 7178. Convention date, June 6, 1940. [Class 15 (i)] [Also in Groups VIII and XIII] Multiple-ply impregnated paper sheets for heat insulation or corrugated board for boxes &c., are made by arranging paper sheets 1, 2, Fig. 1, to form units having internal openended passages, drying the paper if necessary, soaking with asphalt, bitumen, &c., dissolved e.g. in trichlor. ethylene or carbon tetrachloride or as an aqueous emulsion and removing such liquid carrier by circulating air &c., through the passages.of the units. The sheets 1, 2, may be adhered initially as by water-soluble and or heat drying adhesive applied at spaced points 3. As illustrated in Fig. 5, a number of such pads of material are stack ed in rows and tiers with spacing grids in a metal basket 4 allowing free flow of impregnant which is pumped at 20 from a reservoir 18 heated at 47 as by steam, via a valve 21 into an impregnating chamber 13 having a lid 14, an air-circulating conduit 26 with fan 28 and heater 29, an air inlet 48 with a heater 49 and valve 55, and an overflow conduit 25. A conduit 34, 35 in parallel with part of the conduit 26 allows part of the circulating air to be cooled at 33 so that condensed solvent may be returned to a container 15 for mixing with fresh asphalt, provision also being made for some of the air to escape at-31 after solvent vapour has been condensed at 37, 38 and absorbed by active charcoal &c. There is also an air outlet 43 controlled by a valve 44.. In operation after the insulating material has been soaked and drained, hot. air circulation is started to blow out excess impregnating liquid to evaporate most of the solvent, whereupon the valve 55 is opened and heated fresh air drawn in to evaporate the remainder. Alternatively a flap valve 56 may be closed, and finally a damper 46 closed. In modifications the insulating units may be dipped in a separate receptacle or in a receptacle underneath the chamber 13 instead of pumping liquid up at 20.
