Title: Improvements in dry cleaning
IPC: D06F43/00
Filed: 1925-12-31
Abstract: 266,850. Hatfield, A. E., and Achille Serre, Ltd. Dec. 31, 1925. Fats and fatty oils, extracting by solvents; mineral oils, purifying.-Soiled solvent from the washing-machines used for dry cleaning or from wool scouring operations is clarified and dehydrated by treating it with finely divided porous cellular silica of wet density not greater than 12 pounds per cubic foot, e.g. that described in Specifications 229,021 or 234,735, or, according to the Provisional Specification, the materials sold under the registered Trade Marks " filter-cel " or "super-cel," and then filtering the resulting mixture. The filtered solvent is returned continuously to the washing machine, at such a rate that the bath is changed every five minutes or oftener. Reagents which maintain materials in suspension and cause flocculation of the foreign bodies contained in th solvent, may be added. Such reagents include caustic soda or potash, ammonia, the carbonates of sodium, potassium or ammonia, or sodium aluminate or silicate, all of which are afterwards neutralized by an inorganic acid, and the sulphonated oils referred to in Specification 176,540. Removal of any colouring matters which go into solution may be effected by adding also decolourizing carbons or vegetable charcoals. Preferably, the washing-machine, a circulating-pump, and the filter press form a closed circuit with an agitating-tank for mixing the soiled solvent with the cellular silica; or an agitating-tank need not be used, provision being made in the pipe line leading from the washing- machine for adding and mixing the cellular silica and other materials. When the solvent becomes surcharged with soluble matters added thereto or extracted from the goods under treatment, it is subjected to distillation, and the fatty acids of the solvent soaps thus recovered. Sblvent may be removed from the filter cake formed in the filter pass by blowing with air &c., but in large plants employing a number of presses, the cake, after being rapidly blown or washed down. may be fed to a separate press for final drying.

Patent GB-963782-A (GB)
Title: A magazine or cartridge for containing visual and audio information
IPC: G03B31/06
Filed: 1962-08-30
Abstract: 963,782. Magazines for audio tapes and transparencies. KALART CO. Inc. Aug. 30, 1962 [Sept 5, 1961], No. 33306/62. Heading G5R. [Also in Division G2] A magazine (Fig. 2) for use in a projector carries a frame 28 for holding transparencies, a magnetic tape supply reel 13 and a take-up reel 14. The two reels are coupled together by an endless belt 17 and the magnetic tape initially wound on the supply reel 13 is fed to the take-up reel by the action of a capstan 5 (on the projector) in conjunction with pinch roller 25. The tape is guided by idler rollers 19 and 20 between a cushion 24 and the projector sound head 4. In order to effect the automatic rewinding of the tape from the take-up to the supply reel when the tape is freed from coaction with the sound heat and capstan by a magazine release catch (not shown) a spring motor 35 is coupled to reel 13. This motor comprises a flat spring 36 one end of which is fixed to a freely rotatable take-up roller 37, the other end being attached to a drum 39 which is integral with reel 13. The spring is arranged so that it tends to coil itself on roller 37 and is most relaxed when the supply reel is fully wound. As the tape is driven from reel 13 to reel 14, the rotation of reel 13 causes the spring to be wound on drum 39. On release of the tape from the capstan drive, however, the spring effects the rotation of reel 13 in the opposite direction hence rewinding the tape on to this reel. An alternative embodiment (Figs. 4, 5) has the two reels 13 and 14 are mounted on a common shaft. A further embodiment contains an alternative method of releasing the tape from the capstan drive by using an axially displaceable capstan 5a controlled manually or automatically for tape engagement and disengagement. To prevent the tape being pulled off the supply reel, the number of revolutions of the reel may be limited by using a toothed wheel. An adjustable time-setting means may be included for ejecting the magazine at the end of a preset period of time. The ejection means 60 (Fig. 10) is shown as a latching hook 61 for releasing the magazine catch on energization of a solenoid 62. The energization circuit includes a battery 63 connected to parallel conductor bars 64 and 65. A belt 66 is driven between these bars on pulleys 67 and 68 and a contact block 73 suspended from the belt is slidably mounted on bar 65. Rotation of gear train 71-72 drives pulley 68 and hence causes traverse of block 73 along bar 65. Energization of the solenoid occurs when block 73 meets an adjustable switch assembly (not shown) comprising contact springs. The block then returns to its initial position by the action of a spring on pulley 67.

Title: Improvements in magneto-electric ignition apparatus
IPC: H02K21/26
Filed: 1921-12-13
Abstract: 172,957. Bosch Akt.-Ges., R. Dec. 13, 1920, [Convention date]. Magneto-electric machines.-The magnets and pole-shoes of an ignition magneto, in which the length of the armature is greater than the diameter, are formed as hollow cylinders or parts of cylinders, and the magnets lie completely enshrouded within the outer surface of a cylinder of which the pole-shoes form almost the whole or part. Fig. 1 shows magnets 3 and pole-shoes 1 forming a complete cylinder inserted in a casing 2. In Figs. 2 and 3 the magnets 3 and armature 8 are enclosed by the pole-ring 1. In this case the magnets are inserted in the space surrounding the bearing; any number mav be used and, if necessary, at both ends of the armature. In the construction shown in Fig. 5, the annular magnet 3 rotates with the armature 8 so that four flux line changes are produced per revolution. Fixed contacts co-operating with a brush on the rotating armature convey current to the sparking plugs. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the following subject-matter. The permanent magnets are constructed of steel of such high coercive force that the total length placed around the pole-shoe bore is at most equal to half the periphery of this bore; the pole-shoes may be of annular or other form. The magnet 3, Fig. 1 (Cancelled) consisting of a cylindrical bar with a V-shaped groove cut therein, is mounted so that the arms bridge across opposite pole-shoes 1 : pressure is applied by the spring-cover 5. Fig. 2 (Cancelled) shows a modified form. In Fig. 4 (Cancelled) the magnet 3 forms the base of the magneto. In another construction the casing is in one piece; the magnet and pole-shoes are introduced from the end, and a flat spring inserted between the magnet and casing ensures proper contact with the pole-shoes. Several magnets of smaller dimensions may be used. This subjectmatter does not appear in the Specification as accepted.

Abstract: 857,736. Circuits employing bi-stable magnetic elements. STANDARD TELEPHONES & CABLES Ltd. Oct. 23, 1958, No. 33932/58. Class 40 (9). To reduce the switching time of a core 1, the drive winding 2 is connected in series with a drive winding 5 on an auxiliary core 4. The cores and the windings are so dimensioned that the auxiliary core 4 switches first. As the auxiliary core reaches saturation after switching the current gradient is high and core 1 switches to produce a short output pulse. A sine wave input produces alternate positive and negative output pulses. The pulses of one sign may be removed. A number of cores may be connected in cascade so that they are switched successively on each flank of a sine wave. In a modification, cores 4 and 1 have different diameters and carry similar windings. An auxiliary core may be included in' a group of cores defining signal levels in the pulse coding system described in Specification 806,397.
