Title: Improvements in the hardening and tempering of scissor and other blades
IPC: C21D9/18
Filed: 1945-10-09
Abstract: 601,879. Hardening and tempering blades. JACKSTEAD ENGINEERING CO., Ltd., and JACKSON, D. B. Oct. 9, 1945, No. 26375. [Class 72] A method of hardening scissors and like long blades, comprises heating the blade to hardening temperature, clamping the blade directly between metal dies, except for strip along the cutting edge left exposed, and applying quenching fluid to the exposed edge to harden only the edge. The application of quenching fluid may be stopped so that the blade edge can be tempered by heat flowing back from the dies, and the blade then allowed to cool, assisted by further fluid, if desired. In the form shown, a die 14 overlaps a die 13 having a recess 18, to receive a heated blade 19 with the cutting edge 23 exposed. The dies may be closed by a fly-press handle 17 whereupon the table 10 carrying eight dies is rotated, the next pair of dies loaded and the rotation repeated. Rotation every 45 degrees may be checked by a spring-controlled plunger 39 in a bore 40 engaging a notch 41 in a disc 42 on the shaft 11, which may be driven through a worm-wheel 45. As each pair of dies depresses the spring-controlled lever 25, an air or liquid jet 32 from a sump 44, by way of the pump 31 and union 34, strikes the surface 21 and evenly quenches the exposed edge of the blade. At the same time the following pair is loaded and the preceding and now tempered blade reaches, and is further quenched by, the jet 38 from the pipe 37. A modified arrangement for treating small scissor blades consists of two fly-presses having rods depending from the upper dies to depress the plungers of supply valves when the dies are clamped whereby the exposed edge is quenched. The presses are alternately fed by hand, the final cooling fluid being unnecessary.

Abstract: 843,357. Circuits employing bistable magnetic elements. MARCONI'S WIRELESS TELEGRAPH CO. Ltd. June 24, 1958 [Aug. 29, 1957], No. 27237/57. Class 40 (9). [Also in Group XIX] Transfer of information between the magnetic cores of a shift register is delayed until the shift pulse ends. An auxiliary core X normally biased to a 1 state is driven to 0 during each negative shift pulse, (a) Fig. 2, on terminal P and produces a voltage pulse, (b) Fig. 2, across condenser 3. This biasing voltage is connected across condenser AB2, rectifier AB3 and input winding B1 of core B and across rectifiers in the input circuits of other cores C &c. Condenser AB2, which is charged only when a shift pulse changes cam A from state 1 to 0, discharges through input winding B1 of core B when the bias is removed at the end of the shift pulse. If there are no condensers in the circuits linking the cores, the output winding X2 of the auxiliary core X, Fig. 4, is shunted by a resistor 6. Alternatively (Fig. 5, not shown), the winding may be shunted by a condenser and a resistor in series. In another arrangement, Fig. 6, the output winding PX2 of one core PX is shunted by a resistor 6 and the output winding QX2 of a second core QX is shunted by a condenser 3, the bias voltage being taken across the condenser and resistor in series.

Abstract: 1319825 Emulsifiers KRAFTCO CORP 8 June 1970 [18 June 1969] 27570/70 Heading A2B An emulsifier system for use in the food and cosmetic industries comprises 20 to 60% by weight of a mono-ester of glycerol, 80 to 40% by weight of a mono-ester of 1,2-propylene glycol, and at least 1% of a salt. Both monoesters are derived from saturated fatty acids having from 12 to 24 carbon atoms in the molecule, e.g. stearic acid or those derived from soy bean oil, cottonseed oil, lard or tallow. The glycerol ester is at least partly in the alpha crystalline form. The salt has a hydrophilic-lipophilic balance of less than 16 and is able to form hydrogen bonds or van der Waals bonds or both with the esters, but contains no proton-donating groups. Preferably the salt contains atoms of oxygen or of fluorine, and has a readily dissociated cation. Suitable salts are sodium propionate, potassium acetate, sodium laevulinate, dipotassium ortho-phthalate, secondary and tertiary alkali ortho-phosphates, sodium nitrite and sodium fluoride. The system may also include a surfactant, e.g. an ethylene oxide adduct, an ester or a salt of a higher fatty acid, or a solubilizer, e.g. a sugar, milk derivative or gum. The ingredients may be mixed by dissolving the salt and surfaotant, if any, in hot water, stirring in the molten esters, distilling off the water in a vacuum and spray-chilling the residue, or by suspending all the ingredients in hot water, homogenizing and then spray-drying or freezedrying. In Examples, emulsifiers of the invention are added to applesauce, cream, a bread dough; and cake mixes containing also sugar, flour, dried non-fat milk, wheat starch, egg white or whole egg, salt, sodium bicarbonate, sodium aluminium phosphate, vanilla and one or more of cocoa, dextrose, skim milk containing lecithin and monocalcium phosphate.

Abstract: 302,758. Hunt, F. O. Oct. 18, 1927. Indicating flow of liquids. -A device for indicating the flow of fluids through a pipe system comprises a bar magnet within the pipe and acted upon by the flow so that by alteration of position from one limiting position to the other a reversal of polarity is caused to take place at the mid-point of the pipe and is made apparent by an external magnetic indicator. The bar magnet M as shown in Fig. 2, has a mushroom head loosely fitting in the tube and has a spider at its lower end. The indicator is constituted by two bar magnets N to which is attached a disc D, Fig. 3, differently coloured on opposite sides of a diameter thereof, one of which sides is viewable through a semicircular aperture H in a cover plate C. The device may be arranged for a downward or horizontal flow of fluid; in one case the mushroom head will be made super-buoyant and in the other case will be sufficiently bouyant to overcome gravity and have a restoring force such as a light spring applied to it. To indicate the limiting change of level of liquid in a tank the magnet is arranged to float in a pipe communicating with the tank.
