Title: Improvements in milling, planing, turning, or other metal cutting and like tools of the insertable blade type
IPC: B23C5/24
Filed: 1931-05-13
Abstract: 386,645. Insertedblade cutters. HEIDE, H. C., 2, Broad Street Buildings, Liverpool Street, London.-(O.K. Tool Co., Inc. ; 233, Broadway, New York, U.S.A.) May 13, 1931, No. 14132. [Class 83 (iii).] An inserted-blade cutter, such as a face-milling cutter or slotting, broaching, shaping, or turning tool of the kind claimed in Specification 386,307, consists of a holder 1 having recesses 2 which are tapered in both radial and axial directions and are each adapted to receive a cutter element 3 and locking-wedge 4 and additional means are provided for positively locking the cutter and wedge together against relative movement. The face a of the cutter is inclined to the face b at the radial taper, which is approximately 2 while the face c of the wedge is inclined to the face d at the axial taper which is approximately 5. The wedge member, Fig. 8, is formed with a ledge 5 which supports the cutter against inward radial loads. The face d of each wedge and the corresponding face of each recess are respectively formed with serrations 6, 7 which prevent radial movement of the wedges. The wedge and cutter are also positively locked against relative movement by the engagement of a pin 8 on the wedge with one of a series of notches 9 on the cutter. After assembling the cutter and wedge, the combined unit is inserted to its slot and tapped into position. The assembled cutter is then ground to size. For fine radial adjustments of the cutters, the combined cutter and wedge units are removed and adjusted radially over one or more serrations. This adjustment also causes an axial shift of the cutter blade sufficient to allow of re-grinding and trueing to size. For very fine adjustment, the sets of serrations round the holder may be displaced from the preceding set by a fraction of the pitch of the serrations and the compound units may be advanced one or more slots round the holder periphery. For adjusting the blades themselves axially without disturbing the radial adjustment the blade may be advanced over the wedge by multiples of the distance between the notches 9 as shown in Fig. 11. Other forms of engagement between the cutter and the ledge 5 may be employed to obtain finer adjustment in this way. Fig. 13 shows an adaptation of the invention to single point tool 16. Specifications 366,360, [Group III], and 386,234 also are referred to.

Title: Improvements in or relating to silos
IPC: A01F25/22
Filed: 1951-06-14
Abstract: 696,160. Silos; building blocks. THOMSEN, T. V. June 14, 1951, No. 14143/5,1. Classes 20(i) and 87(i) A silo has ventilation ducts 2 terminating beneath projections 17 on the inside of the silo wall 1. The silo consists of stone, concrete, or brick blocks 1 and is built over a duct 3, a central vertical duct 4 extending the height of the silo and opening into the ducts. A pipe 12 in the duct 3 communicates with a blower 13 and can be moved to engage the lower end 11 of the duct 4 which has aperture 6 in its walls and encloses a piston 14 which can be positioned in the duct 4 to direct air through the grain stowed in the silo. The external, walls of the silo can have projections too, and the ducts 2 can be horizontal, or of inverted V shape to prevent the entry of rain. The projections mav be formed integrally with the blocks 37, as at 38 in Fig. 8, the ventilation ducts 40 being if desired formed in the adjacent lower block 39, or a separate projection, e.g. a sheet metal part 36, Fig. 7, may be attached to a block 20 adjacent the duct 35. If the projections are integral with the block, they may extend the full width of a block or only part width. The ducts 2 or the projections may be formed by tubes embedded in the blocks or in the mortar between vertically adjacent blocks. The piston 14 may comprise two flexible discs vertically spaced a fixed distance apart on a bar extending along the duct 4, or may comprise two piston members spaced vertically apart and connected by a flexible hose to form a bellows.

Title: Improved means for damping cereal grain
IPC: B02B1/04
Filed: 1931-05-14
Abstract: 377,343. Damping grain. SIMON, Ltd., H. and WATTS, G., Bird Hall Lane, Cheadle Heath, Cheshire. May 14, 1931, No. 14263. [Class 58.] The flow of water through a notched weir for the purpose of damping grain is regulated by a cover-plate that is actuated by a servomotor, controlled by the grain flow. The weir plate a controls the rate of water delivery from a tank b maintained at overflow level over a side c by water admitted from a main tank d through a port at the bottom of the tank water being supplied to the main tank through a float valve f the float being in an overflow compartment h from which the overflow water is returned to the main tank at a uniform rate by a pump i. The water passing through the notched weir plate a leaves the apparatus by the compartment j and pipe k. A cover-plate 19 slides in guides m and is raised and lowered by a servomotor. The grain enters the machine at the top n passes over a plate controlled by a counter weight p and falls on a plate carried by parallel links and controlled by a counterweight s a cam u being fitted on the spindle of the counterweight. One arm of a bell-crank lever v bears on the cam and the other engages a projection upon a frame x guided by rollers y in a slot in a frame 2 on the side of the device. The frame 2 also contains a slide 3 on which arms 5, 6, having teeth on their inner sides, and pressed apart by a spring 7 are pivoted. The slide 3 is connected to one arm of a bell-crank lever of which the other arm is connected by a link to an adjustable lever actuating the weir cover-plate 19. The slide moves on a pivotally mounted block 4 and is actuated by a singletoothed wheel 9 mounted on a constantly rotating shaft and adapted to engage one or other of the racks on the arms 5, 6 ; an eccentric 8 is also mounted on the constantly rotating shaft and rocks the slide 3 on its pivot so that the racks can be lifted clear of the tooth of the wheel 9. The racks however are controlled by lugs on the frame x these lugs being adapted to engage stepped parts of the arms so that in accordance with the position of the frame r the one or the other arm may be held down against the action of the spring 7 when the slide 3 is rocked by the eccentric and so the corresponding rack engaged by the tooth and the weir coverplate actuated.

Title: Production of conjugated diolefines
Inventor: BARCLAY JOHN LYNN
IPC: C07C5/48
Filed: 1960-04-26
Abstract: A catalyst for the oxidation of mono-olefins to diolefins comprises mixtures of antimony oxide with an oxide of tin, molybdenum, tungsten and/or titanium.  Such catalysts are prepared by mixing or coprecipitating the oxides and activating by heating to 500 DEG -1100 DEG C.  The catalyst mixtures may be supported on silica, and may contain graphite.  The preferred catalyst comprises tin and antimony oxides in an atomic ratio of tin to antimony between 0,1 and 20,1, which is prepared by mixing the products of reacting the respective metals with nitric acid or by hydrolyzing, e.g. with aqueous ammonia, water cationic salts of the metal, e.g. an aqueous solution of stannic chloride and antimony pentachloride.  The catalyst is preferably washed and dried and if any metal is in a lower valency state is heated in oxygen and an inert gas such as nitrogen, carbon dioxide, or steam raising the temperature from 330 DEG -650 DEG C. over a period of not less than eight hours before activating by heating to 500 DEG -1100 DEG C.ALSO:Conjugated diolefins are obtained from mono-olefins having a chain of at least 4 carbon atoms by reaction with molecular oxygen over a catalyst comprising antimony oxide alone or mixed with a polyvalent metal oxide, e.g. molybdenum, tin, tungsten or titanium.  The catalyst which may be supported on silica or alumina is preferably a mixture or chemical combination of tin and antimony oxides in an atomic ratio of tin to antimony of 0.1-20 : 1, and is activated by heating to 500-1100 DEG C.  The mono-olefin, e.g. butene-1 or -2 or 2-methylbutene-1 or -2, may be mixed with nitrogen, steam or a paraffin and the oxygen may be added as air so that the feed contains 1-25% by volume of olefin and 1-21% of oxygen.  The reaction is effected at 200-500 DEG C. for 1-30 seconds.
