Title: Improvements in or relating to the grinding of rotating eccentric knives
IPC: B24B3/44
Filed: 1933-02-28
Abstract: 411,244. Grinding rotating knives. MUHLBAUER, E. C., and MOLINS MACHINE CO., Ltd., 2, Evelyn Street, Deptford, London. Feb. 28, 1933, No. 6029. [Class 60.] Rotating eccentric knives the edges of which during a period at least of their rotation are moving substantially in their own direction, that is, are without movement normal to the direction of the edge, are sharpened during. such period by a grinding element rotated in definite time relationship to the rotation of the knife, and having its grinding surface shaped to maintain the desired form of the eccentric edge. Fig. 1 shows the knife 1 of a cigarettemaking machine, of the construction described in Specification 324,379, [Class 130], which is mounted on a carrier 2 on the link or yoke of a universal joint between relatively-inclined shafts 4, 5, so that at the time of cutting the cigarette rod the knife is moving axially at substantially the same speed as the rod, whilst in the position shown the edge is substantially without axial movement, that is, is moving in its own direction. In this position it is sharpened by a pair of grinding wheels 7 having the form of a cylindrical sector, Fig. 2 the surface 11 of which is eccentric to the axis of rotation, the wheels being driven through gearing from the shaft 5. By suitable choice of ratio of the angular velocity of the wheels 7 to that of the knife, e.g. 5À5 : 1 or 4À5 : 1, each wheel is caused to grind one face of the edge at alternate revolutions of the knife. The difference between the radial distances of the leading and trailing ends 11<a>, 11<b> of the grinding surface from the axis are such as to produce the required degree of eccentricity of the edge of the knife. In a modification, one wheel only is employed, the burr being removed by a flat grinding disc below the shaft 4. Another form of grinding wheel is illustrated having a surface comprising about three-quarters of a turn of a tapering helix and rotating about its axis, which is inclined and lies in a plane perpendicular to the shaft 4. A further modification is in the form of a worm thread rotating about its axis, which is perpendicular to the plane of the knife, the side of the thread forming the grinding surface.

Title: Improvements in or relating to the production of alcohols
IPC: C07C29/16
Filed: 1950-03-10
Abstract: Alcohols are made in a one-stage process by contacting olefinic hydrocarbons containing 2-5 carbon atoms per molecule with CO and H2 and with not less than 5 per cent or not more than 30 per cent by weight of water based on olefine in the presence of a cobalt-containing catalyst at about 250-450 DEG  F., and about 2500-3500 p.s.i.g.  A solvent is generally used, e.g. product alcohol or a primary alcohol containing one more carbon atom than the olefine used or a hydrocarbon.  In an illustration propylene in a primary butanol or hydrocarbon which preferably contains the catalyst 0.5-3 per cent by weight of olefine of a high molecular weight cobalt soap, is reacted as above with about an equimolar mixture of H2 and CO at a preferred temperature of 250-375 DEG  F., the ratio of solvent to olefine being 1 to 4 by weight and the amount of added water preferably does not exceed 20 per cent. Alcohols are separated by fractional distillation and filtration from aldehydes and other products and unreacted compounds.  A colloidal suspension of cobalt metal or oxide may replace the soap catalyst.  A table is given of a series of experiments using propylene and various quantities of water, it being shown that comparatively high yields of alcohol are obtained using the defined amounts of water, and that normal as against isoalcohols are produced.  Specification 631,316 is referred to.

Abstract: 327,523. Stone, B. H. Feb. 25, 1929. Electric stoves.-The stove is provided with a scaled balance which is adjusted so that the heating circuit is opened automatically when the weight of the contents of the vessel being heated is reduced by evaporation to a predetermined value. The vessel is automatically lifted away from the heating unit simultaneously with the opening of the heating circuit. The heating circuit is automatically closed when a vessel is placed on the stove. The heating unit comprises upper and lower refractory members 27, 28 mounted on a two-part casing 10, 15, and a heating wire 36 in two sections interconnected in series by a coil 66 and housed in grooves in the member 28. The switch controlling the unit comprises contact pins 63, 66 co-operating with mercury cups 57, 58 and interconnected by a conductor 65. The contact-pins are mounted on an insulating support 62, fixed to a member 43 secured to a rod 40 making pivotal knife-edge contact with a pin 39'. The member 43 is provided on one side with a screwed rod 45 carrying adjustable balance weights 46, 47 and on the other side with an arm 44 carrying a member 50 supporting a rod 53 fitted at its upper end with a block 65 adapted to contact with the underside of the vessel to be heated. The rod 53 is prevented from turning by a pin engaging a slotted member 69 secured to the rod. Normally the balance lever formed by the rod 45, the member 43, and the arm 44 is tilted so that the member 43 abuts a stop 49 and the pin 64 is withdrawn from the mercury cup 58. In using the stove for concentrating a liquid contained by an evaporating dish 37, the weights 46, 47 are so adjusted that the former compensates for the weight of the empty dish and the latter registers with the number on the scale 48 corresponding to the final weight of liquid required. When the dish 37 is placed in position the block 56 is depressed until a groove on its underside engages a knife edge formed on a member 54 secured to the heating unit, and the balance lever moves to a central position so that the pin 64 enters the cup 58 to close the heating circuit. When the weight of the contents of the dish reaches the desired value the balance returns to its normal position lifting the dish and breaking the circuit at 64, 58. A sheet of asbestos 74 shields the balance, from the heating unit.
