Title: Improvements relating to slicing machines
IPC: B26D1/143
Filed: 1931-10-23
Abstract: 384,038. Slicing-machines. NAAMLOOZE VENNOOTSCHAP MAATSCHAPPIJ TOT VERVAARDIGING VAN SNIJMACHINES VOLGENS VAN BERKEL'S PATENT EN VAN ANDERE WERKTUIGEN, and BERKEL, W. A. VAN, 33, Boezemsingel, Rotterdam, Holland. Oct. 23, 1931, No. 29430. [Class 28 (ii).] In a disc-knife reciprocating- table slicing-machine, a clutch connection is so arranged that, when the clutch is engaged and the flywheel turned, the carriage is moved to-and-fro and the knife is rotated, and when the clutch is disengaged and the carriage moved to-and-fro by directly pushing and pulling it, the knife is rotated either by the carriage or by power. As shown, the flywheel 7 is rotatable either by a folding handle 9, or by a motor 10 pivotally mounted at 10a to control the frictional engagement of the pulley 11 with a pneumatic tyre 12 on the flywheel. The flywheel shaft 15 carries a bevel wheel 22 meshing with a bevel 21 on a shaft 19 carrying a carriageactuating crank 20, and has an extension 15a carrying a bevel 17 meshing with a bevel 18 on a shaft 16a having an extension 16 on which the knife-driving sprocket 14 is mounted. Either the wheel 17 or 18 is associated with a free-wheel mounting so that the knife is only rotated by the flywheel when the flywheel is rotated clockwise. The crank 20 is connected by a rod 23 to an arm 24 which is, or may be, clutched to a concentrically mounted toothed quadrant 31 by a spring-pressed pin 33 axially slidable in a boss at the end of the connecting- rod 23 and engageable with a hole in the quadrant. The pin 33 is pulled out by a knob 34 which is turned to maintain the pin disengaged. The quadrant has an extension arm 30 pivoted at 29 to a rod 28 connected to the carriage, and engages with a pinion 32 having a free-wheel mounting on the shaft 16. In operation, when the pin 33 is engaged with the quadrant, the knife and carriage are actuated by rotating the flywheel by power or hand. When the pin 33 is disengaged and the flywheel rotated, the arm 24 oscillates idly, and the knife is rotated by the mechanism 17, 18, 16, 16a, 14, whilst the carriage may be reciprocated, with an indefinite stroke, by hand. When the pin 33 is disengaged and the flywheel is not rotated, the manually imparted reciprocations of the carriage oscillate the quadrant 31 and rotate the knife through the free-wheel pinion 32, shaft 16 and sprocket 14. When the carriage is manually reciprocated, the feed is preferably effected by hand with the aid of a fixed, adjustable gaugeplate. Specification 384,026 is referred to.

Title: Improvements in cutters for metal-cutting and like machine tools
IPC: B23C5/24
Filed: 1928-10-15
Abstract: 303,496. O. K. Tool Co., Inc., (Assignees of Weddell, R. R. Jan. 6, 1928. [Convention date]. Milling-cutters; tools and tool-holders.-In an inserted blade cutting tool for metal-cutting or other machine-tools, which may be either rotary or non-rotary, the body or holder is provided with one or more recesses which taper in two perpendicular directions and the blades are similarly shaped to be secured therein by wedging action. Serrations are provided on one side of each blade to coact with serrations on a side of the recesses. As applied to a face milling-cutter the blades 12 are secured in recesses 11 in the body 10, the blades being inclined slightly to the axis of the cutter and also to radii in order to provide cutting rake. The blades and recesses are tapered in each direction, as shown in Figs. 2 and 5 and the blades have two cutting edges 12<a>, 12<b>. In order to adjust the blades, after re-grinding or otherwise, the serrations on the blades are made to engage with different serrations in the recesses thus causing each of the cutting edges to be displaced. The relative amounts of such displacement are determined by the relative amounts of the taper in the two directions, As applied to a side milling-cutter, the blades 19, Fig. 7, are inclined to the axis of the cutter alternately in opposite directions and are tapered alternately as shown and also converge towards the axis. The serrations in the recesses may be displaced progressively round the body so that moving a blade from one recess to the next will adjust the blade by an amount less than the pitch of the serrations, and in the case of the side cutter the progressive arrangement affects alternate recesses in opposite directions.

IPC: C09B1/02
Filed: 1957-09-25
Abstract: Alpha - hydroxy - beta - nitro - anthraquinones are made by treating an anthraquinone containing a halogen atom or an hydroxy or a nitro group in an alpha-position, but which is not substituted in a beta-position, with a nitrite or complex nitrite of an alkali-metal and an acid in a water-miscible organic solvent. When anthraquinones containing one alphahalogen, -hydroxy or nitro group are used the halogen or nitro group is converted to hydroxy and a nitro group is introduced into the position beta to this group.  When more than one halogen, hydroxy or nitro groups are present in alpha positions each of the halogen and nitro groups is converted to hydroxy and a nitro group is introduced into a position beta to an hydroxy group. Further treatment according to the above process results in the introduction of a second nitro group beta to an hydroxy group. Examples are given.  The Provisional Specification refers to the preparation of alphahydroxy - beta - nitro - polycyclic quinones in general.  Specifications 610,117 and 670,720 are referred to.ALSO:Alpha-hydroxy - beta - nitro - anthraquinones are made by treating an anthraquinone containing a halogen atom or an hydroxy or a nitro group in an alpha-position, but which is not substituted in a beta-position, with a nitrite or complex nitrite of an alkali-metal and an acid in a water-miscible organic solvent.
