Abstract: 185,916. Sunderland, S., and Midgley, A. M. July 22, 1921. Gear-cutting.-A shaping-machine for cutting the teeth on racks by means of a multiple cutter or for performing like operations, has a wedge feeding-mechanism and a rectilinear indexing-device. The cutter c is reciprocated in a vertical plane by means of fast and loose pulleys, gearing, and a Whitworth quick-return motion. The blank m<2> is mounted on a table m, and is fed towards the tool by a wedge m<4> having rack teeth engaging a pinion rotated through gearing o<4> and a worm drive from a belt pulley o<1>, connected to the main drive shaft. An adjustable screw m<5> on the wedge contacts with an adjustable block n on the machine framing to limit the depth of feed, a friction drive in the feed train being caused to slip. When one set of teeth has been cut, the table is traversed to the position for the next set to be cut by a screw m<1>, operated by hand or power, until two stops s<3>, on the table and framing respectively, make contact. The stops are set at the correct distance apart by a gauge rod s<4>.

Title: Improvements in or relating to boosters
IPC: F15B3/00
Filed: 1959-06-10
Abstract: 858,577. Hydraulic intensifiers. REGIE NATIONALE DES USINES RENAULT. June 10, 1959 [July 17, 1958], No. 19873/59. Class 69 (2). An hydraulic intensifier comprises a large-diameter, low-pressure piston 4 resiliently mounted on the rod 17 of a small-diameter, highpressure piston 18 to facilitate their axial alignment. The skirt of the piston 4 has members 6, 11 for packing and guiding the piston in its cylinder and is of aluminium cast to a steel crown 5. A rubber member 14 is retained in the crown and connected to the rod 17 of the piston which is slidable in a cylinder 8 supplied with oil from a bell-shaped chamber 21. Low-pressure fluid, such as compressed air, supplied to a port 3 moves the piston 4 downwardly and forces the piston 18 to compress the oil in the cylinder 8. The space 27 beneath the piston 4 is connected by ports 26 to the atmosphere and during the downward movement of the piston 4, air is trapped in the space and compressed so that, when the low-pressure supply is disconnected, it acts to return the piston to its upper position. The casing of the intensifier is in two parts 1, 2 secured together by bolts, one of which is hollow and provided with a plug for filling purposes, and another of which is adapted to contain a float and gauge to indicate the level of oil in the chamber 21.

Title: Improved method for the utilization of fruit and vegetable refuse
IPC: A23L2/02
Filed: 1920-07-09
Abstract: 147,833. Matzka, W. June 8, 1918, [Convention date]. Manures.-Refuse from fruit and vegetables, such as pea and bean pods, banana skins, and especially asparagus waste, is treated to obtain fibres suitable for spinning, food or flavouring material, and manure. The waste is crushed with water between rollers and then placed with the extracted juice and water sufficient to cover it in an autoclave, where it is heated under pressure for between two and three hours. The fibres are then strained free from the juice and again passed between rollers. They can then be dried and used for coarse weaving, ropes, &c., or they may be boiled with an alkali for two or three hours, washed, pressed, and dried, when they are suitable for finer fabrics. The solid residue can be used for manure, either as it is, or after drying and neutralizing the alkali. The liquor is evaporated to any desired consistency, or to dryness, and can be used for making vegetable-soup cubes, seasonings, sauces, and the like.

Abstract: 1305291 Brazing AEROQUIP AG 24 April 1970 [14 May 1969] 19885/70 Heading B3R [Also in Division G1] In a method of brazing in which the temperature of the workpiece rises on the application of heat to a first peak at which the braze material begins to melt and flow, whereupon the temperature falls off somewhat before rising again to a desired brazing temperature below the previous peak, temperature sensing and control means are used to terminate the application of heat only in response to the second detection of the desired brazing temperature. Brazing apparatus for brazing together two workpieces, e.g. tubes 26, 28 includes a light tube or fibre-optic means 50 placed so as to sense changes in emission of light from the joint area upon heating and to transmit the light to a photo-electric cell 56 arranged to control the termination of heating at a preselected level of emission of light, i.e. at a preselected temperature. The brazing head 10 includes two jaws 20, 22 adapted to surround a sleeve member 30 which surrounds the workpieces 26, 28. Annular cavities 32, 34 in the sleeve 30 are provided to hold brazing material and an electrical heating coil (not shown) surrounds the cavity 38 in which the workpieces are held. The electrical control circuitry is arranged to ignore the first peak in temperature (the melting point of the braze material) and to cut off the current only when the temperature rises again to the preselected brazing temperature.

In a further' modification (Fig. 5) the rims of the cups are chamfered in opposite directions as at G, G<1> so as to fit one within the other, the metallizing being applied at G<2>. The outer edge of at least one rim is preferably further chamfered back, as at G<3>, for ease in soldering. The two elements may be of any cross section, and one element may be a short tubular ceramic cover fitting on to the end of a larger element. The condenser may be impregnated before or after assembly, in the latter case through one end hole which is subsequently sealed by soldering.

Filed: 1959-06-13
Abstract: Diborane, or partially halogenated boron hydrides, are obtained by vapour phase reduction of a boron trihalide with H2 at elevated temperature in the presence of a Group IB metal in elemental form, e.g. Cu or Ag, BF3, BCl3, BBr3, or BI3, may be reacted with H2 at 250 DEG -950 DEG C. and atmos. up to 50 atms. pressure for 0.01-2.5 secs., in proportion 1-60 mole H2 per mole trihalide.  H2 is bubbled through BCl3 and the resulting vapour mixture contacted with the metal which may be as little as 0.01% or a bed of granular metal. The volatile reaction products B2H5Cl, BHCl2, B2H6, and HCl are separated from H2 by condensation in a liquid N2-cooled trap at -196 DEG C. HCl is volatilised at -120 to -107 DEG C. and B2H6 is volatilised at 0 DEG C. under 2 atms., and as B2H6 is removed more BHCl2 and B2H5Cl is converted to B2H6.  BCl3 may be recycled.
