Title: Improvements in or relating to apparatus for forming filling and sealing containers
IPC: B65B51/26
Filed: 1950-12-15
Abstract: 703,850. Packaging machines. STERLING DRUG, Inc. Dec. 15, 1950 [Dec 17, 1949], No. 30636/,50. Class 94 (1) [Also in Groups V and VI] In an apparatus for forming and filling plastic containers, in which a plastic tube as it advances is filled and sealed by cross-sealers comprising a pair of relatively.movable sealer arms which move into and out of tube.sealing relationship, move with the tube during the sealing, retract and return, a pair of relatively movable fingers press the filled tube above one seal and just prior to the subsequent seal to express excess material and hence control the volume of the sealed container, In the drawings (Fig. 1) a plastic tube is fed from roll 40 over roller 44  to a tube slitting' and filling device where the tube is slit longitudinally as it passes-taut over a former 48 with an inset knife 50 to permit the lateral insertion of a filling tube 56 (Fig. 4), the plastic tube being then longitudinally resealed by heated rollers 34, 36, adherence to which is obviated by a film of interposed non- sticking material fed from roll 41. The filled tube 92 (Fig. 1) passes down to the cross sealing mechanism and the finished containers leave through shoot D. The sealing mechanism (Fig. 5) is mounted on a head 94 moving on vertical guides 112 under the action of an arm 96 actuated by a cam 110 capable of being driven at variable controlled speeds. A block 113 on head 94 carries a fixed heated sealing knife 114 whilst the opposed sealing knife 150 is mounted on a member 139, actuated in a lateral direction by rod 116 and cam lever 118. The volume control fingers 124, 134 are shown in detail in Fig. 6. The finger 124 slides in block 113, being urged towards tube 92 by spring 126, An adjustable stop 132 can engage against the face 117 of block 113. An adjustable rod 142 terminating in an abutment 140 determines the distance between finger 124 and finger 134, the latter being mounted on a spring actuated sleeve on rod 142. The rod 142 is mounted in member 139 operated by rod 116. The member 139 is mounted on rod 144 integral with block 113, and a spring 146 urges member 139 towards the tube against the action of the rod 116. When the latter retracts (by cam lever 118) the member 139 is urged towards the tube by spring 146 causing abutment 140 to engage finger 124 and carry it forward until stop 132 engages face 117, at which point the tube 92 has been compressed to the requisite degree. Still under the action of spring 146 the member 139 continues to move forward until the knife 150 carried thereon co-operates with heated knife 114 to cross-seal the tube. The whole mechanism moves down with the tube on head 94 until the seal is complete when rod 116 is again actuated, retracting knife 150 and the finger 134. The member 94 then moves upwardly to restore the mechanism to its original position. A safety device automatically cuts off the flow of filling material if too small a quantity is being fed to the tube, by gauging its cross section prior to sealing.

Title: Improvements in devices for indicating or controlling the weight of cigarettes leaving a cigarette machine
IPC: G01G19/00
Filed: 1931-11-07
Abstract: 376,605. Weighing-apparatus fitted to cigarette-making machines. UNIVERSELLE CIGARETTENMASCHINEN-FABRIK J. C. MULLER & CO., 48, Zwickauerstrasse, Dresden, Germany.-(Assignees of Neuerburg'sche Verwaltungsges, Cologne, Germany.) Nov. 7, 1931, No. 30917. Convention date, May 4. [Class 143.] In a method of checking the weight of the cigarettes leaving a cigarette machine, each weighing of a group of cigarettes taken periodically from the delivery member of the cigarette machine and supplied to a balance is registered by counters, of which one counts the weighings of correct weight, whilst the others count the weighings of over or underweight. The cigarettes from the cigarette machine are fed by a grooved drum 1 to a conveyer band 2 which may deliver them to a packing machine. Periodically, a pivoted member 3 is actuated by a cam 7 so as to deflect a predetermined number of cigarettes from the drum into a weigh pan 9 suspended from a balance beam 11. The weigh pan is held against upward movement beyond the mid-position of the beam, by a plunger 14 controlled by a lever 13 and cam 12. After a group of cigarettes has been deposited in the pan, the cam 12 raises the plunger 14 and the beam 11 assumes a position dependent on the weight of the cigarettes. A spring arm 21 on the beam is thus adjusted over a series of electrical contacts 24 .. 28 connected to counters 34 .. 38. A bent lever 29 is now actuated by the cam 12 so as to press the spring arm 21 against one of the contacts and thus actuate the corresponding counter. The readings of the counters inform the operative of the numbers of weighings of standard, overweight or underweight dimensions and the range of divergence. The continued rotation of the cam 12 depresses the plunger 14 and pan 9 until a stationary abutment 19 opens a discharge gate 9b and drops the.cigarettes on to the conveyer 2. Instead of employing electric contacts 24 .. 28, the counters may be actuated by optical, photo-electrical, pneumatic or mechanical means actuated by the throw of the spring arm 21. Permanent records, apparatus for giving.-An upward extension of the spring arm 21 may carry a style or pin 32 by means of which a strip 33 may be perforated or inscribed at each weighing.

Abstract: 930,853. Electron microscopes. PHILIPS ELECTRICAL INDUSTRIES Ltd. Sept. 10, 1959 [Sept. 13, 1958], No. 30922/59. Class 39 (1). The shutter for an electron microscope comprises two parts 3, 4 pivoted at 6 to a base-plate 2 and held closed by two compression springs 11, 12 each attached at one end to the shutter part and at the other to a pivot 10 on a rod 9 which may be moved into an operative position by rotating a shaft 15 having a driving pin 18 engaging cams 19 on the rod 9. Rotation of the shaft 15 moves the rod 9 and hence the spring pivot 10 to 10a in which position the springs tend to urge the parts 3, 4 apart. One such part, however, is prevented from movement by a rod 24, which has two arms engaging one or other abutment 22, 27, the selection being made by axial movement of the rod 24. Rotation of the rod 24 releases the engagement of the selected arm and abutment thereby allowing the other part of the shutter to open. In the closed position the parts 3, 4 overlap slightly. A separate rod 24 may operate on each part separately.

Title: Improvements in machines for end-grinding rolls
IPC: B24B5/24
Filed: 1924-12-30
Abstract: 239,093. Skerrett, H. N. (Timken Roller Bearing Co.). Dec. 30, 1924. Rollers, treating; bevelling.-In a machine for end grinding rolls such as the conical rolls used in roller bearings, the rolls are successively fed to a rotary work-holder which is automatically adjusted axially at one of a number of spaced positions according to the size of the work, and 'after grinding the work-pieces are automatically ejected and sorted. The hollow spindle 2 driven from a pulley 3 is slidable in its bearings 4, the normal forward position being determined by a collar 5. The rolls 9 are fed successively from a shoot 14 to a conical seating 8 in the spindle by means of a push-rod 15 mounted in a cradle 10 provided with a roll seat 13 and traversed on a cross slide 11 to bring the pushrod into alignment with the spindle by means of a cam 17 on a shaft 18. The push-rod is moved axially to position a blank by means of a ram 20 operated from a cam 22, the stroke of the ram being determined by the engagement of a collar 25 with a bushing 24. The cross slide 11 also carries an inclined slide 28 on which the grinding-wheel 27 is traversed to effect the end-grinding operation. Thus when the push-rod 15 is brought into alignment with the spindle, the grinding-wheel is at the same time withdrawn. In order to position the spindle a rack 29 moving endwise with the spindle engages a pinion 30 on an arm 34 carrying a ratchet member 35 engaged by a pawl 36. When a work-piece is pushed into position the spindle is moved back more or less according to the length of the work-piece and on withdrawal of the push-rod the spindle is moved by the weight of the arm 34 until the pawl locks the ratchet member. The spaced positions of the spindle are thus determined by the pitch of the ratchet teeth and all rolls ground when the spindle is in any particular position will have large ends of the same diameter. The finished work-piece is ejected by a rod 37 operated through a lever 38 from a cam 39, and at the same time an extension 40 of the ejector-rod disengages the pawl 36 and allows the spindle to return to its forward position. The automatic sorting means comprises a drum 42 having shoots 41.. the drum being moved to receive the blank in the appropriate shoot by means of lever mechanism 43, 44 connected to the ratchet member 35.
