Title: Improvements relating to electromagnetic sound recording or pick-up devices
Inventor: DUTTON GILBERT FARADAY
IPC: H04R11/08
Filed: 1947-05-29
Abstract: 658,245. Phonographic recorders. ELECTRIC & MUSICAL INDUSTRIES, Ltd. May 29, 1947, No. 14265. [Class 40 (iv)] [Also in Group XXXVIII] In an electromagnetic sound recording head in which an armature adapted to carry a stylus is mounted to vibrate about an axis in bearings lined with resilient material, an L-shaped spring having one arm coaxial with the above axis eliminates the tendency of the cutter to produce a spurious hill and dale cut in hard record blanks. As shown, the main casting 4 is secured by a clip 6 on to a bush 1 about which it may rotate, ball..bearings 8 forming a bearing against a flange 2. The casting may be located relative to the flange so that the cutter is in its effective position by a pin 11 in a recess 12. The armature 29 which carries the stylus is formed integrally with tubular pivot shafts 21 which are covered with resilient material 23 and clamped to a base-plate 26, Fig. 6 (not shown), so that the flattened end 31 may vibrate between the laminated pole-pieces 13 attached to the permanent magnet 16. The L-shaped spring which also serves as a centring spring is soldered at one end 32 into a central hole in the end of one of the pivots, the other end 34 being attached to the main casting by a screw 35. The operating coil 18 around the armature is supported on blocks and the leads are looped at 19 before passing through the bush 1 to prevent strain when the cutting head is rotated. The spring may be designed to have any natural frequency but it is preferred that this frequency should fall within the audible range and that the peak response is eliminated electrically.

Title: Process for the manufacture of organosiloxane copolymers of high molecular weight
IPC: C08G77/10
Filed: 1962-04-12
Abstract: In making linear diorganosiloxane copolymers of high molecular weight by equilibrating at least two immiscible diorganosiloxane polymers of low molecular weight in the presence of a phosphorus-nitrogen compound as catalyst, one of the siloxanes is added to the other in stages and after each addition the resulting mixture is equilibrated to a homogeneous mass before the next addition is made.  Preferably a siloxane having a faster condensation rate is added to one having a slower condensation rate.  The starting siloxanes contain at least 98 mol. per cent of R2SiO units and up to 2 mol. per cent of RSiO3/2 and R3SiO1/2 units, wherein each R is a hydrocarbon (saturated or unsaturated) or halohydrocarbon radical. The catalysts are phosphoronitrile halides and certain organonitrogen derivatives of phosphorous and phosphoric acids. The reaction can be effected at room temperature or at temperatures up to 120 DEG  C.  In a typical Example: (1) a mixture of a phenylmethylsiloxane (A), a dimethylsiloxane (B) and an end-blocking methylsiloxane, was mixed with (PNCl2)4 in methylene chloride at 80 DEG  to 85 DEG  C. with stirring until the original turbidity had disappeared, a further portion of siloxane (B) was added, again producing a turbidity, and the mixture was again heated until the turbidity had disappeared, this procedure being repeated until the whole of siloxane (B) had been added.

Title: Improvements in the reduction smelting of chromite-bearing materials
Inventor: UDY MARVIN J
IPC: C22C35/00
Filed: 1959-04-29
Abstract: In the smelting of chromite-bearing ores and concentrates in an arc furnace the charge contains alumina, silica and magnesia (with or without calcium oxide) in such proportions that the resultant slug contains these constituents in the ratio 0.25-1.25 : 1 : 0.5-1.5 by weight, any calcium oxide being calculated as magnesia.  The process may be operated to produce ferrochromium in a single stage, or a first stage may consist of partial reduction using either carbonaceous or non-carbonaceous reducing agent to produce iron or steel or a low-chromium ferroalloy together with a slag enriched in chromium.  The reducing agent may be ferrochromium or ferro-chromium-silicon made by complete reduction of the ore.  The slag is then smelted to produce a high-grade ferrochromium.  A medium-carbon alloy may be obtained by using coke as reducing agent in a furnace having a non-carbonaceous lining.  To obtain a low-carbon alloy, a high-carbon alloy produced in two stages as described above is smelted with silica and a reducing agent to produce a ferrochromium alloy containing about 50% of silicon, which is then smelted with more of the enriched slag from the first stage. As a modification the ferrochromium-silicon may be obtained directly in the second stage.  Preferably in all cases the ore should initially be stabilized to constant composition by heating at 900-1350 DEG  C.  Specification 646,162 is referred to.

Filed: 1923-06-04
Abstract: 223,948. Woosnam, A., (Reid, J.). June 4, 1923. Liquid - fuel furnaces; forced draught systems.- In forced draught air supply to multiple furnaces of large capacity in which a fan, or other air supply delivers to branches of the main air passages and in which each branch terminates only in its own furnace, the system is formed throughout with fairly swept walls so as to prevent abrupt change of direction of the inflowing air. Fig. 1 shows an arrangement of air passages from the air main b to a multiple furnace, successive branches c and d leading off the air chambers a of the furnace fronts by passages formed without abrupt bends. Various modifications of the main principle are described in connection with two three and four furnace boilers. In one modification for a three-furnace boiler, the trunk supply is bifurcated to pass to points near the two outside furnaces where each passage is again split by a dividing plate, the two smaller branches leading to the central furnace. Each passage is led into the circular air chamber at the furnace front tangentially. In leading the air supply to a fourfurnace boiler the passages may be twice divided. In water tube boilers having a series of oil burners the air main c, Fig. 9, may be flared out and divided by partitions e<2> into ducts d' connected tangentially to the oil burning fronts. The division by the partitions may be in two stages as shown. Specifications 157,679 and 220,079 are referred to.

Abstract: 458,231. Making hollow glassware. HARTFORD-EMPIRE CO., 333, Homestead Avenue, Hartford, Connecticut, U.S.A.- (Assignees of Rowe, G. E. ; 72, Somerset Street, Wethersfield, Connecticut, U.S.A.) May 25, 1936, No. 14745. Convention date, May 24, 1935. [Class 56] A method of making hollow glassware in a single mould consists in compacting a charge of glass in the mould to form a blank, expanding the blank by blowing and drawing-out while out of contact with the mould, and then blowing the parison thus formed to its final shape. The mould 6, Fig. 2, is recessed at 9 to embrace a ring mould 11, and the holders 12 and 13 for the ring mould sections have flanges which engage a complementary flange on a head 17, whereby the head is held tightly against the ring mould. The head 17 contains a neck pin 19, and it is provided with ports 22, 26 for suction and compression, respectively. The ports are opened and closed by the movement of the neck pin into or out of the ring mould. A hollow head or closure 27, which fits snugly within the mould cavity, has its underside perforated with small holes and is carried by a hollow stem 31 through which suction or compression can be applied to its interior. In operation, a charge of glass is placed in the closed mould 6 and is compacted around the neck pin 19 by suction applied through the port 22, by pressure of the head 27, or by compressed air applied through the head, or by all of these means. After the blank is formed, suction is applied to the interior of the head 27 so that the head holds the blank, the neck pin 19 is withdrawn, and the mould 6 is opened. The blank is next developed into a hollow parison, as shown in Fig. 4, by elevating the head 27 and by air admitted through the ring mould. When the formation of the parison is completed, the mould 6 is closed and the parison is blown to its final shape by the admission of compressed air through the port 26.
