Abstract: 1,212,492. Lapping. S. MESSERSCHMIDT. 8 Jan., 1969 [8 Jan., 1968], No. 1133/69. Heading B3D.  A method of lapping balls between two coaxial discs which are formed with grooves in which the balls run, comprises  (i) rotating one of the discs, the other disc being held stationary and formed with a sectorshaped recess;  (ii) feeding balls to the recess;  (iii) receiving balls from the recess; (iv) guiding the balls, after each rotation between the discs, through a magazine; and (v) interrupting, when the balls have become substantially identical in size and shape, the connection between the sector-shaped recess and the magazine; and (vi) allowing the balls to rotate continuously between the lapping discs until they have the required maximum surface finish.  A lapping machine has a lower lapping disc 1, with grooves 3, rotated in the direction 12. An upper lapping disc 5 can be raised but is non- rotatable; it has a sector-shaped recess 7. The discs 1, 2 are mounted eccentrically within an annular magazine 8 comprising a plate 14 with wall 15, rotated in the direction 13, and a stationary inner wall 16 having a gap 17 in register with the recess 7. A sheet steel guide member 18 secured to the disc 5 extends into the recess.  In operation, balls 4 make alternate circuits round the working space between the discs and round the magazine.  When the balls are substantially identical in size and shape, the guide member 18 is removed and the gap 17 of the wall 16 is closed by a member (24) secured to the disc 5. The balls between the discs make repeated circuits round the working space while the other balls remain in the magazine.

Abstract: 793,129. Making cartons. BALJAK CORPORATION. Jan. 18, 1956 [Feb. 11, 1955], No. 1689/56. Class 18. A device for setting up and interlocking the corners of lined cartons comprises a plunger and die, the plunger having retractable finger elements designed to press inwardly portions of extensions of side walls causing them to lock with the end walls which they overlap. A lined blank intended to be set up by the device has extensions 20-23 on side walls 12, 13, these extensions overlapping the end walls 16, 17 externally and engaging behind tongues 72- 75. End wall extensions 28-31 lie against the inside of the side walls. Lid flaps 38-40 fold down outside the carton with their tongues 44, 45, 48 engaging slits 46, 47, 49 respectively. Edges 52, 53 of the tongue 48 lock with edges 50, 51 of the slit 49. The corners are locked by parts 67 of the extensions 20-23 being pressed inwardly to lie behind parts 66 of the walls 16, 17, this causing cut edges 64, 65 to abut. The liner forms corner gussets embracing the extensions 28-31. The plunger comprises fingers 103 which, in one embodiment, are fixed adjustably to arms 105 pivoted at 104 and biased by springs (not shown) to retain the fingers in their outer position. Arms 110 carry rollers 108 which are engaged by cam surfaces 114 in the die to cause pivoting inwardly and downwards of the fingers 103. The plunger may be attached to a box assembly machine of the type described in U.S.A. Specification 2,655,843 and as in that machine, the blank may be placed on the die by a suction feeder during which process the sides and ends are bent up slightly from the base, extensions 28-31 are folded in by arms 121, and catches 123 secure the blank in the die. As the plunger descends, die members 122, 116, 117 fold up the side and end walls, studs 102 on the plunger press the tongues 71-74 outwardly and die cam surfaces 120 guide the extensions 20-23 to behind the tongues. The cam surfaces 114 then engage the rollers 108 and the fingers 103 are pressed inwardly to form the lock. Stripper members 124 remove the completed carton from the plunger beneath the die. In an alternative form of plunger, Fig. 14, the fingers are pivoted on the lower ends of arms 110<SP>1</SP>, mounted as were the arms 110, and have cam surfaces 128 on inner extensions. As cams 114 press rollers 1081 inwards, the surfaces 128 engage with members 129 and cause the fingers to pivot inwards and downwards as before. Studs 1021 having the same function as the studs 102, are mounted on the ends of the arms 1101 and are thus withdrawn from operation when the fingers are in action. Specifications 642,446 and 668,523 are referred to.

Title: Improvements in bottle soaking and washing apparatus
IPC: B08B9/26
Filed: 1922-01-19
Abstract: 190,929. Gould, H. T. Jan. 19, 1922. Bottles, washing. - In rotary-drum machines of the kind described in Specification 1864/14 wherein the bottles are transferred automatically from one to another of a series of drums, improved means of feeding and ejecting the bottles are provided. In the form shown two drums 1 rotate in separate tanks and each have two series of cells, formed between the central rim 3 of a wheel 2 and sheetmetal rings 5 mounted on each side of the wheel, by transverse partitions 6 so that two bottles are fed and delivered at once. Bands 36, 37 around the inner top and outer bottom circumferences of the drum respectively retain the bottles in the cells, and plungers 7 act in conjunction with a feed-bar 9 to feed and deliver them when the cells are horizontal and adjacent a feed and delivery table 8. The drums are driven by pawls 18 pivoted on a slotted link 20 which is reciprocated by a cam 22 on the main shaft 17 so that the pawls engage ratchet teeth 4 on the central rim to rotate the drums one cell at a time, while another cam 16 on the main shaft reciprocates a, rack 14 meshing with a pinion 15 driving another pinion 12 which, through a rack 11 on a connecting-rod 10 reciprocates the plungers 7 and feed-bar 9, the plungers 7 and feed-bar 9, the plungers parsing through the stationary cells. A spring- pressed pawl 23 prevents any backward rotation due to an unbalanced load and another pawl on the slotted link 20 prevents the drum rotating more than the space of one cell. Driven off the cam 16 is a red 31 having a rack 30 which oscillates a pinion 29 driving another pinion 27 which reciprocates the table transversely by means of a rack 28 on its under side. In operation two bottles will be delivered from each drum on to the table 8 which has divisions to receive them, the table will then move sideways so that the bottles from the second drum are placed clear of the machine for removal, those from the first drum are placed opposite the second, and two dirty bottles which have been placed on the out-jutting end of the table, Fig. 2, are carried opposite the first drum. In the next movement the bar 9 will push the four bottles into the cells, when the drum will be rotated one notch, and the operations repeated. The number of drums may be varied and the direction of rotation altered so that the bottles may be delivered empty or partly filled with washing- fluid.

Title: Improvements relating to the manufacture from cellulose esters of artificial products, such as artificial silk, films, plastic masses, intermediate layers for safety glass, laquers and the like
IPC: C08B3/22
Filed: 1933-01-19
Abstract: For the manufacture of artificial silk, films, plastic masses, intermediate layers of laminated glass, lacquers &c., there are employed cellulose fatty acid esters obtained from primary cellulose tri-esters in the preparation of which have been used catalysts which do not remain in combined form in the cellulose ester, in particular with the exclusion of sulphuric acid, phosphoric acid, bisulphates and sulphuryl chloride, by subjecting these esters in the undissolved condition to a gentle after-treatment with acid saponifying agents in such a manner that the acid content of the ester does not diminish by more than 5 per cent.  Operating in this manner, the useful properties of the primary esters are retained and there is an improvement in the elasticity and extension in many cases even with a reduction of acid content of one per cent; substantially no change of solubility characteristics occurs, except in the case of mixed esters.  The primary cellulose esters may be prepared with the aid of the catalysts of Specification 363,700, and in particular by a process such that the original fibrous structure of the cellulose is retained, as by the addition of cyclohexanol acetate, ethyl acetate, benzene toluene or ligroin.  In examples, artificial silk, films &c. are made from primary cellulose tri-acetates prepared with the aid of perchloric acid or zinc chloride as catalysts, after subjecting these esters to treatment at room temperature with 3 N-hydrochloric acid, 1-1,5 N-nitric acid or 1,5 N-perchloric acid or a mixture of acetic and perchloric acids; or from a cellulose acetate-isovalerianate made according to the process of Specification 396,575, after treatment at 20 DEG  C. with 1,5 N-nitric acid.
