Title: Improvements in or relating to preparations of chlorinated and other non-polar volatile solvents
IPC: D06L1/01
Filed: 1958-11-17
Abstract: Spot-removing compositions are obtained in jelly form, suitable for packaging in collapsible aluminium or plastic containers, by mixing with a volatile non-polar oil, fat or grease solvent, e.g. di- or perchlorethylene, carbon tetrachloride, or white spirit, but preferably trichlorethylene, less than 5%, but preferably more than 4% by weight of the total mixture of finely-divided silica having a ratio of surface area to mass of 175-300 m2/g.  The silica used is suitably an aerogel having a fibrous, sponge-like structure and a moisture content not above 2%; it is preferred to use the products known under the Registered Trade Marks "Santocel 54" and "Aerosil", the former having a particle size range of 0,5-3m , and the latter a range of 10-40m m .  If required, inert fillers such as finely-divided starch and kieselguhr may be incorporated.

Filed: 1965-08-27
Abstract: 1,113,956. Radio navigation. STANDARD TELEPHONES & CABLES Ltd. 27 Aug., 1965, No. 36917/65. Heading H4D. Relates to a modification of a TACAN system wherein, in addition to the single lobe and the nine-lobe antenna system a three-lobe, threeantennae system is provided. At the receiver the 45 c/s. signal produced from the amplitude modulations of the received three-lobe radiation is used to control the passage of the 15 c/s. bearing signal to the phase comparator for comparison with 15 c/s. reference signal, in such a way that the effects of site distortion of the 15 c/s. bearing signal are reduced. In one embodiment, Fig. 2 (not shown), pulses having a width equal to 90 degrees of their respective signals are produced from the 15 c/s. and 135 c/s. bearing signals and the 45 c/s. signal and fed to a coincidence circuit. The coincidence circuit then produces pulses at 15 p.p.s. having a width equal to the 135 c/s. pulses and these pulses are fed to the phase comparator. In a second embodiment, Fig. 3 (not shown), the 15 c/s. bearing signal is passed through a variable phase shifter, controlled by the 45 c/s. signal such that it is brought into phase therewith.

Abstract: 1,009,501. Dynamo electric machines. A. V. ROE & CO. Ltd. Oct. 31, 1961 [Oct. 31, 1960], No. 37408/60. Heading H2A. A constant speed rotary drive for a relatively light and constant load comprises a variable speed input shaft 20 driving a magnetic hysteresis clutch 22 coupled to an eddy current damper 25, 26, the output being taken from the intermediate shaft 24 for example through gearing 28 and shaft 27. Fig. 5 shows a unitary form of the drive in which the hysteresis clutch comprises a preferably laminated driven cup 31 surrounding one end of a permanent magnet rotor 22. The other end of the rotor is connected to the output shaft 27 and forms with a stationary low resistance cup 30 and a laminated magnetic core ring 32 an eddy current-drag damper. It is explained that the torque transmitted by the clutch is constant with speed whereas that of the damper is proportional to speed so that the speed of shaft 27 will have a value independent of the speed of shaft 20.

A method of transporting and firing coal comprises preparing flotation coal, which consists of a coal slurry having no more than two-thirds of coal by volume, pumping the flotation coal through a pipe-line towards a furnace, reducing the water content to approximately one-sixth by volume by such means as a centrifuge, revolving screen or " couching," and burning the combustible content of the mixture in the furnace. Alternatively, the water content of the slurry may be reduced, after pumping, until the coal is no longer fluid, the extracted water being replaced by raw or fuel oil to form a fluid mixture. Said mixture is pumped to a furnace and burnt using a burner suitable for use with a solid/ liquid suspension, or, if the particle size is too great, the mixture is burnt in a cyclone furnace.

Abstract: 1402306 Protective arrangements; electric couplings ROBERT BOSCH GmbH 16 Aug 1972 [24 Sept 1971] 38116/72 Headings H2K and H2E A system for charging a battery from an A.C. generator having a bridge rectifier with associated D.C. terminals includes a reversed polarity protective device comprising a fuse and a twoarmed metal spring element on one of the terminals, the limbs of the element carrying contacts which are spaced apart in the unstressed condition of the element and at least one of which is insulated from the element and connected to the respective pole of the rectifier. The contacts are engaged to complete a battery charging circuit by the act of tightening a battery lead on the terminal, and the fuse is connected to the element such that should an attempt be made to connect a battery with incorrect polarity, a circuit is completed via the fuse on initial contact of the battery lead with the terminal, whereby the fuse blows. As shown, both D.C. terminals 36, 37 have two-armed spring elements 34, 35 welded thereto and carrying contacts 39, 40, 42, 47 of which the last three are insulated by washers, e.g. 41, 43 from the terminals and elements. The fuse 32 and an indicating lamp 33 are connected between the contact 42 and the element 35, a diode 30 is connected between the contact 42 and the element 34, and the rectifier 23, 24 is connected between the contacts 40, 47. Irrespective of the order in which the battery leads are applied to the terminals, a circuit is initially completed through the diode 30 and fuse 32 before the tightening of the terminals closes the contacts 39, 40 and 42, 47 to complete the charging circuit. In a simplified arrangement, Fig. 2 (not shown), the element 34 is not provided, and in another arrangement. Fig. 1 (not shown) a single element similar to 34 is used without the diode, but a relay may be connected across the fuse and open contacts in the charging circuit when the fuse blows.

Abstract: 1,161,121. Punched cards and selection apparatus. A. REYROLLE & CO. Ltd. 8 Sept., 1966 [8 Sept., 1965], No. 38389/65. Heading G4M. A card bearing graphic information, e.g. typewritten words or diagrams, is also provided with information in the form of coded rows of holes, the holes occurring in areas which coincide with or overlap areas bearing graphic information, the size of the holes, and the positions of the rows being chosen so that, in the areas where the holes overlap graphic information, no significant obliteration of the graphic information occurs. Before punching the card, the operator inspects the graphic information and makes a mark adjacent any areas in which the significant detail is exceptionally small, e.g. punctuation marks, or decimal points. These areas are subsequently avoided when punching the card, the positions of the rows of holes being chosen from a predetermined set of rows, greater in number than those actually required, each row position being indicated by a pre-printed index mark, or being freely chosen from any area of the card. If a row is erroneously punched, a notch or hole is made in one edge of the card adjacent the affected row. Cards bearing a selected pattern of holes in a row of 55 index positions are separated from a pack as follows. The cards are passed serially through a sensing station comprising 55 datasensing photo-cells 39, an error-notch detecting photo-cell 45 and a card presence detecting cell 46. Switches 53 are opened when the desired pattern contains a hole at the corresponding index position. Transistors 51, 52 are " on " and "off" respectively when the associated photo-cell is dark, the conduction states being reversed when a hole is sensed. When a card row which includes the desired pattern of holes is sensed, a through path to the emitter of transistor 55 is set up via switches 53 and transistors 52, so that, provided the row in question has no associated error notch to turn " off" transistor 55, an S.C.R. 60 fires to actuate a deflector blade solenoid 57 and direct the card to a " selected " pocket. The leading edge of the next card produces a pulse from photo-cell 46 to fire S.C.R. 66 thereby turning off S.C.R. 60 and restoring the deflector blade to its inactive position. Two such selection stations may be arranged serially to perform selection in two successive stages. The selection circuitry may be modified to detect the presence or absence of holes or for rendering selected photo-cells inoperative. The circuit shown in Fig. 5 responds to patterns having holes at positions additional to the selected positions.
