Title: Improvements in the process of casting metals
IPC: B22D7/00
Filed: 1920-07-08
Abstract: 147,625. Windhausen, F. Nov. 15, 1915, [Convention date]. Casting-machines; casting processes; moulds; casings.-In casting metals, particularly steel and iron, the metal after being poured into the mould is allowed to solidify only in part without heating the upper part of the metal to keep it molten as is described in Specification 26335/10 and the still molten or pasty central portion, which contains a higher percentage of impurities than the solidified portion, is run out of the mould and replaced by metal from the ladle. The separated metal may be returned to the furnace. The top of the casting is either broken prior to pouring out of the mould or the breaking may be rendered unnecessary if the metal is shaken or stirred during solidification. The mould c is carried in a frame mounted on trunnions h, and is tilted to pour out the molten or pasty portion by a pinion and rack b operated hydraulically. The frame may also be used to shake the metal during solidification. The Specification as open to inspection under Sect. 91 (3) (a) states that the top of the casting may be kept molten by heat during solidification. This subject-matter does not appear in the Specification as accepted.

Abstract: 1358742 Induction motors; winding layouts SIEMENS AG 9 June 1971 [10 June 1970] 19789/71 Heading H2A A single-phase motor, e.g. for a washing machine, has at least two stator windings of different pole numbers to provide two different speeds, the winding having the lower pole number being connectible so that the coil sides in adjacent slots can be traversed by currents in opposite directions to provide a third higher pole number and a creep speed differing from the first two speeds. Fig. 2 shows diagrammatically a motor having a four-pole main winding 26 and an auxiliary winding 27 associated with a starting capacitor 28. A third stator winding 40 arranged as shown in Fig. 1 provides either two poles when supplied from terminal 25 and terminals 23, 24 bridged together, or sixteen poles when supplied from terminals 23, 24 alone. Connection or disconnection of terminals 23, 24 is effected by a switch 32 operated in conjunction with speed control switches 31, 33. In the sixteen pole configuration of winding 40 the current directions are shown by the lower set of arrows in Fig. 1, i.e. opposite in adjacent coil sides, and in the embodiment shown, winding 26 or 27 remains operative so that winding 40 acts as a brake winding.

[Classes 40 (iii) and 40 (v)] The impedance of a piezo-electric crystal is increased by subdividing the electrodes and interconnecting the divisions in such a way that different parts of the crystal are connected in series or series-parallel combinations. Fig. 5 shows an arrangement in which each electrode is divided into three parts A, B, C, A<SP>1</SP>, B<SP>1</SP>, C<SP>1</SP>, the parts AA<SP>1</SP> and CC<SP>1</SP> being series-connected in parallel into part BB<SP>1</SP> relative to terminals 4, 5. The actual layout of the electrodes is shown in Fig. 8 which is a developed view in which 8, 9 are the centre lines of the upper and lower faces of the crystal and 10, 11, 12 and 13 are the edges. Electrodes A and B are combined to form electrode D while B<SP>1</SP> and C<SP>1</SP> are combined to form electrode E. Electrodes C and A<SP>1</SP> are connected by strips of plating 14, 15 on the sides of the crystal. Fig. 9 shows the arrangement of Fig. 8 modified to provide two impedances by dividing the electrodes along the centre lines 8, 9, two pairs of terminals 16, 17 and 18, 19 being provided. Electrode arrangements for series connection, and for working on the higher harmonics are also described. Fig. 14 shows a wave filter of the symmetrical lattice type comprising two equal length impedance branches and two equal diagonal branches connected between input terminals 24, 25 and output terminals 26, 27.

Title: Metal composites
IPC: C22C47/14
Filed: 1960-06-07
Abstract: A composite metal structure, in the form of rods, bars and plates, consisting of a metal matrix such as titanium or a titanium-aluminium-vanadium alloy and fibres of a different metal such as molybdenum is formed either by compacting and sintering a mixture of the matrix metal powder and the fibres followed by hot working to orientate the fibres, or alternatively the fibres may be disposed axially in a malleable container such as a steel tube which is then packed with the matrix metal powder and hot worked. In an example, Mo fibres 0.1 inch to 0.25 inch long and 0.01 inch diameter are mixed with Ti powder or an alloy powder of Ti 90%, Al 6%, V 4% and compacted at 70 tons p.s.i. and vacuum sintered at 1800 DEG  F. The compact is canned in mild steel extruded to 5/8 -inch rod at 1800 DEG  F., the case is stripped and the compact is recanned in stainless steel and hot rolled at 1450 DEG  F. The cladding is removed and the rod is cold rolled and then annealed at 1350 DEG  F. In the alternative method the fibres are initially orientated in a steel tube, the metal powder is packed into the tube and the assembly is hot rolled at 1450 DEG  F. to 1800 DEG  F.  The fibres form 3% to 60% by volume of the composite.

Abstract: 148,149. Kaufmann, P. Oct. 18, 1913, [Convention date]. Passing materials through fluids; vats, construction of; vats, heating contents of. - A machine for dyeing linen, cotton, union, and other heavy goods with vat and sulphur dyes comprises a vat or vats 1, into which the goods 7 are passed, so that when thoroughly wet and free from air they sink to the bottom of the vat. This movement is facilitated by the method of heating the vat, which consists in placing a steam pipe 4 behind a partition 3 in the vat. The upper and lower parts of the partition are perforated to allow the liquids to circulate through the vat. The fabric 7 passes through squeezing rollers 9, 10 to the vat 1, sinking to the bottom 2, which is curved as shown. It then passes to the squeezing-rollers 14, 15 and to the folder. A scraper 11 or an endless apron prevents the fabric from being rolled up on the lower roller. The apparatus may be used for treating goods in endless-band form. The Specification as open to inspection under Sect. 91 (3) (a) comprises an apparatus, Fig. 1, (Cancelled), with a feeding-tank, containing dye, which is used when dyeing with light shades and with indigo; thence the fabric passes to the vat 1, of which two are shown. This subject-matter does not appear in the Specification as accepted.
