Title: Improvements relating to cutting tools having tips or inserts of tungsten carbide orlike hard materials
IPC: E21B10/54
Filed: 1940-06-29
Abstract: 536,001. Making cutting-tools. CROFTON & CO. (ENGINEERS), Ltd., C., and GASCOIGNE, J. C. June 29, 1940, No. 11055. [Classes 83 (ii) and 83 (iv)] Brazing.-In brazing tips of tungsten carbide or the like to the bodies of cutting tools such as rock drills, coal-cutting picks and metal turning or boring tools, the part of the body which is to receive the tip is first formed with small closely spaced but isolated depressions 18, such as may be produced by a centre punch. In this manner the tip may be held in place by a clamp without the risk of squeezing out the whole of the molten bronze. Each blade 10 of a rock drill blank may be recessed at 12 to receive a tip 14. After producing the depression on the surface 16 the surfaces 16, 20 are coated with bronze and a sheet of steel wire gauze 22 is secured to the surface 16 by heating and applying flux and bronze. The exposed surface of the gauze is then coated with bronze on the tip applied and held in position by a clamp during brazing. The gauze prevents the bronze from collecting in a globule or pool. The raised rims produced by the centre punch are removed by filing or grinding so that the original surface between the depressions remains smooth and continuous. The extremities of the blades are finally ground to the shape shown.

Abstract: 839,671. Cam mechanisms. HUSQVARNA VAPENFABRIKS A.B. April 8, 1958, No. 11089/58. Class 80 (3). [Also in Group VII] In a sewing machine the angular position of a feed-regulating member 9, which is pivoted at 10 and is biased clockwise by a spring 13, is controlled by a cam follower 25 selectively engageable with side-by-side rotary control cams a, b, c, the cam follower being operatively connected with a handle 45 and the arrangement being such that rotation of the handle serves to shift the follower from one cam to another and also to lift the follower away from the cams while said shifting takes place. Follower 25 is slidably mounted on a rod 26 carried by a bracket 27 pivoted at 28 to the machine frame. A pin 29, projecting from bracket 27, is slidably engaged with a flange 30 at one end of a lever 15 pivoted at 18, at its other end, to a slidably mounted block 20. A nose 14 on lever 15 bears against a projection 12 on guide 9, whereby the follower is biased against the cams. A rotatable sleeve 44 is provided at its inner end with a face cam 76 having four steps 51 to 54, is provided intermediately with a radial cam 77 having lobes 66 disposed between the steps 51 to 54, and carries at its outer end the handle 45. A bar 31 embracing the follower 25 is fixed to one end of a slidable rod 33 the other end 32 of which is biased by a spring 34 to serve as a follower for cam 76. A follower 65, co-operating with cam 77, is provided on a lever 79 and the latter is connected by a lever 67 and link 80 to bracket 27. The arrangement is such that on rotation of handle 45 follower 32 co-operates with respective steps 52 to 54 to move follower 25 slidably from cam c to cam a, while follower 65 co-operates with cam 77 to rock bracket 27 for lifting follower 25 away from cams a, b, c during sliding movement of follower 25. When handle 45 is moved to position follower 32 on flat 51, follower 25 is moved clear of the cams a, b, c and an abutment 75 on bar 31 rocks a lever 73 against a spring 78 to free one arm 72 of a two-armed lever pivoted at 18, whereby the other arm 70 is biased by a spring 69 into engagement with an abutment 71 on member 9. The angular position of the latter may then be controlled by a handle 40, the hub 39 of which abuts a finger 21 rigid with block 20. It is stated that the invention may be applied also when the control cams are axially displaceable instead of the follower.

Title: Process for breaking wet oils
IPC: C10G33/04
Filed: 1957-04-08
Abstract: Wet oils are freed from water by the addition of an emulsion breaker which is a poly-alkylene glycol, soluble or dispersible in water, having in its molecule a hydrophobic middle group and two terminal hydrophilic groups connected one to each end of the middle group. Thus, the emulsion breaker may have the formula: <FORM:0854921/III/1> wherein x, y and z are whole numbers, the central hydrophobic group of the molecule being composed of the residue of polypropylene glycol and being attached to two hydrophilic end groups composed of residues of polyethylene glycol. Alternatively, the central hydrophobic group may be composed of the residue of polybutylene glycol or may be composed of the residue of a compound formed by reacting polypropylene glycol or polybutylene glycol with adipic acid or other organic compound containing two reactive hydrogen atoms in its molecule.  The process is particularly applicable to the breaking of mineral oil emulsions.  In the examples, wet mineral oils are freed from water by the use of emulsion breakers which are polyglycols formed by condensation of polypropylene glycol with ethylene oxide.

Filed: 1957-04-09
Abstract: 828,865. Arcing preventing in switches. VANG, A. April 9, 1957, No. 11504/57. Class 38 (5). An arrangement for preventing or minimizing arcing at switch contacts 13, 19 when a load circuit is opened, comprises a condenser 14, means for charging the condenser and means for discharging the condenser across the switch contacts in opposition to the load current when the contacts are opened. The means for discharging the condenser comprise a transductor or (as shown) a gas-filled triode 18 which is normally non-conducting due to the negative bias applied to the control grid 28 from a bias source 30. The switch blade 13 has an extension 20 which remains in contact with an auxiliary contact 21 when the contacts 13, 19 initially open so that a pulse is applied to the primary winding 22 of a transformer 23 and induces a pulse in its secondary winding 27. This renders the control grid 28 sufficiently positive for the triode to fire and permit the condenser to discharge. The arrangement shown is for D.C. circuits but Fig. 2 (not shown) illustrates a similar arrangement having two oppositely-polarized condensers and two triodes for application to A.C. circuits.
