Title: Improvements in the manufacture of rotary cutting tools
IPC: B23P15/34
Filed: 1927-02-24
Abstract: 290,761. Tscherne, A. Feb. 24, 1927. Milling-machines; milling-cutters; reamers. - Rotary cutting tools such as milling-cutters, reamers and the like have cutting-edges which are inclined to the axis of rotation of the tool are made by mounting the blank on a rotatable arbor carried by a reciprocating slide which is moved under a profiled milling-cutter while the blank is simultaneously oscillated to a varying degree to produce a tapered groove and to form oppositely inclined helical teeth. The table T of a milling-machine which is movable transversely of the milling-spindle Z and is mounted on the longitudinal slide S, carries a housing 1 supporting in bearings a hollow shaft 2. The latter carries a toothed segment 3 engaging a vertically-sliding rack 4 which has a pin 6 engaging a block working in a slotted arm 28 pivoted at 7 in a bearing 9 fixed to the slide S. The arm 28 is oscillated by means of a crank 10 on a driven shaft 14. The hollow spindle 2 carries a spindle 32 which is provided with a dividing- plate 16 coacting with an index pin 17 secured to the spindle 2. The blank A is secured by nuts 21 to a mandrel 20 which is carried between centres 22, 23 and is connected to the spindle 32 by a coupling-sleeve 19. In operation, the end b of the blank is brought beneath the profiled milling-cutter H and the blank is oscillated through the lever 28, rack 4 and segment 3. As the slide T is moved to the right, Fig. 2, the rack pin 6 approaches the pivot 7 of the lever 28 so that the oscillation of the blank gradually decreases to zero and a tapering groove f forming a cutting-edge c and a back edge c' is produced. The blank is then indexed and the operation repeated. In a modification, Figs. 11 and 12 a frame B, pivoted on a lower frame R at 69 carries the blank A between centres 42, 43, the dividing movement being effected by means of a notched disc 44. A slot 65, provided in the frame B, is engaged by a block 59 actuated by an adjustable crank-disc 57 driven through worm gearing from a pulley 52. During the traversing of the table F under the milling- cutter H, the frame B is thus rocked about its pivot 69 to produce a tapering groove. After completion of a groove the blank is indexed and the operation repeated. When all the grooves 63 have been milled out, the blank is reversed end for end on its mandrel and the oppositelytapering grooves 64 are formed in a similar way.

Title: Improvements in or relating to the preservation of food
IPC: A23L3/3409
Filed: 1945-03-02
Abstract: Foodstuffs, e.g. fresh or dried fruit, vegetables, meat or sausages, are sealed in moisture-proof containers, having at least one wall or window formed of the material known under the Registered Trade Mark "Cellophane" or "Pliofilm," together with a measured amount of ethylene oxide, propylene oxide or methyl bromide, which volatilizes at normal room temperature to provide a sterilizing atmosphere to kill micro-organisms, such as mould, bacteria or yeasts, and gradually permeates through the wall or window until all traces thereof have disappeared from the container.  The sterilizing agent may be dissolved in, or mixed with, a medium capable of lowering the vapour pressure, e.g. water, ethyl or other non-toxic alcohol, ethylene dichloride or propylene glycol, measured amounts being obtained by dipping therein small pieces of absorbent material such as cardboard or blotting paper.  When propylene glycol is used, direct contact with the foodstuff is avoided by enclosing the impregnated blotting-paper &c. in a small unsealed packet made of "Cellophane" or "Pliofilm."  Dried fruits, such as prunes, are immersed in hot water to bring the moisture content to about 29 per cent and then allowed to cool to about 130 DEG  F. before introduction into the containers.  A solution of ethylene oxide and water or a mixture of methyl bromide and water may be frozen and used in the form of powder or pellets, e.g. in a small packet made of paper or cloth.  The frozen solution or mixture may be packed with frozen foods, such as vegetables, meat, fish, sausages or fowl, either precooked or in raw condition, the containers being stored at a low temperature, or it may be introduced into the containers prior to quick freezing of the food therein.

Title: Process for modifying glass and other materials
Inventor: PLUMAT EMILE
IPC: C03C21/00
Filed: 1968-02-06
Abstract: 1,212,881. Treating glass. GLAVERBEL. 6 Feb., 1968 [25 April, 1967; 30 Aug., 1967], No. 5839/68. Heading C1M.  In a process for modifying bodies of glass or glass-ceramic or portions thereof, the body or body portion is successively contacted with a gas which is and/or is maintained in an ionizer state wholly or in part in the immediate vicinity of the body by means of a discharge of electricity, ions of the gas being caused or allowed to enter the body. The electrical action may be supplemented by one or more flames located in or adjacent the path of such discharge. A continuous glass sheet 2, Fig. 1, is chemically tempered during its formation. As it moves up the drawing tower it passes two sets of treating means. Vertically displaced carriages 12, 13 are mounted one on each side of the sheet 2 and are reciprocable transversely thereof. Each carriage 12, 13 holds a pair of hollow electrodes 14, 15 or 16, 17 at 90 degrees inclination with the lines of intersection in the plane of the glass. Lithium nitrate vapour is fed into the electrodes and is ionized by the resulting arc. To assist in the ionization and aid the ion exchange action each carriage has affixed across its lower end a gas burner 22, 23 having a plurality of jets extending thereacross but excluding the marginal 6 cm of the sheet. The carriages reciprocate within these limits, thus leaving these edges untoughened and therefore easily trimmable. Hydrogen may be introduced into the vicinity of the flames. The temperature of the sheet varies from 700 C. as it approaches the first carriage to 600 C. as it leaves the second carriage. Sodium ions in the surface of the glass sheet are replaced by lithium ions from the ionized gas. In an alternative embodiment for treating a hollow glass article 47, Fig. 4, two pairs of electrodes 39, 40, 41, 42 are located adjacent its upper edge. Two vertically spaced main electrodes 39, 40 are composed of core-pieces containing in solid form a substance to be volatilized and then ionized for the treating process. These electrodes are both located on the outside of the vessel, one being above its rim. The two auxiliary electrodes 41, 42 are located one on each side of the vessel wall, the tops of these electrodes being level with the rim of the vessel, and also are located intermediate the two main electrodes. A high-frequency alternating voltage is applied to the main electrodes and a direct-current voltage to the auxiliary electrodes, during which time a turntable 43 on which article 47 is placed is being rotated. As the rim portion is being heated a controlled ion exchange takes place around the vessel rim. This method may be used for tinting the glass, e.g. using copper electrodes. Other suitable elements whose ions can be used for ion exchange are calcium, magnesium, barium, lead, tin, iron, manganese, nickel, cobalt and selenium. The presence of ionized gas in desired vicinities may be reduced or prevented by locating cooling means adjacent those parts.
