Patent GB-777614-A (GB)
Title: Improvements in or relating to expanded bitumen
Inventor: WATKINS RONALD CHARLES
IPC: C08J9/00
Filed: 1954-12-14
Abstract: A cellular material containing a major proportion of bitumen and a minor proportion of a synthetic thermoplastic resin is prepared by forming a dough comprising the bitumen and synthetic resin, a blowing agent, and a non-volatile plasticizer, heating the dough to gasify the blowing agent whilst applying external pressure to prevent full expansion of the dough, cooling the dough, releasing the pressure, and further expanding the mass by reheating.  The bitumen may consist of a natural bitumen, or a derivative of coal tar, or a residue from a petroleum distillate. The non-volatile plasticizer may comprise dioctyl phthalate, polypropylene sebacate or adipate, or a butadieneacrylonitrile copolymer.  As a blowing agent may be used ferrous oxalate, sodium bicarbonate, ammonium carbonate, a mixture of sodium nitrite and ammonium chloride, dinitrosopentamethylene tetramine, diazoaminobenzene, p, p1 oxy bis (benzene sulphonyl hydrazide), a, a-azo-bis-(iso-butyronitrile), 1, 1 azo-bis-(cyclohexane carbonitrile), benzene sulphonyl hydrazide, urea, or biuret.  The synthetic resin is preferably an ethenoid resin, e.g. polyvinyl chloride or a copolymer thereof.  To the non volatile plasticizer may be added a volatile solvent or a monomer polymerizable at the gassing and expansion temperatures as described in specification No. 716,366 [Group IV(a)].  In one example a dough is prepared comprising 31 parts by weight of a bituminous material sold under the trade name "Carbitum Pitch," 25 parts polyvinyl chloride, 4 parts lead stearate, 4 parts calcium stearate, 17 parts diazoaminobenzene, and 19 parts dioctyl phthalate.  The mix is heated in a mould in a steam heated press for 25 minutes at 325 DEG F. under a pressure of 1 ton per square inch.  The mould is cooled for 30 minutes, and the pressure then released.  The partially expanded material is heated in an oven at 190 DEG F. for 2 hours.  In two other examples the bituminous material is a product sold under the trade name "Catarex Pitch," and the plasticizer comprises a mixture of acetone and polypropylene adipate, and of styrene, acetone, and polypropylene adipate, respectively.  In a further example the blowing agent consists of benzene sulphonyl hydrazide and the plasticizer is a butadiene acrylonitrile copolymer.  Specification 716,495 also is referred to.
Patent GB-449021-A (GB)
Title: Improved plugs for insertion in walls, floors, ceilings, and other places
IPC: F16B13/06
Filed: 1934-12-18
Abstract: 449,021. Wall plugs. HAMILL, W. W., Woodlands, Forest Lane, Chigwell, Essex. Dec. 18, 1934, No. 36232. Addition to 412,631. [Class 89 (i)] A rubber or like plug according to the parent Specification has its cross-sectional shape modified to enable the plug to fit cavities of various sizes and to provide increased resistance to turning under the rotative action of the expanding screw or like instrument According to one feature, the periphery of the plug is provided with longitudinal pieces anchored so that their free ends can have a radial component of movement. The flaps 7, Fig. 4, formed by the tangential slits 2 may be of equal or different lengths ; the peripheral surfaces of the flap portions may be concentric with, or eccentric to the axis of the plug, and the slits may be tapered or parallel sided. On insertion in an oversize cavity, the flaps will ensure a good fit, and will prevent rotation of the plug as it is expanded ; finally the flaps merge into the body of the plug. In a modification, Fig. 5, radial arms 11 carry segments 12 which may be symmetrical or not, according to whether equal resistance to turning in either direction is desired. The periphery of the plug may be roughened, as by longitudinal groovings or by diamond markings. According to another feature the bore is non-circular so as to provide limited areas in contact with the periphery of the expanding instrument, and so that pressure is transmitted to the periphery in predetermined directions. The cross-section of the bore may be a polygon having as many sides as there are peripheral flaps, as e.g. a triangle, Fig. 4. The bore may comprise channels 16, Fig. 8, and projections 17. The flap-forming slits may have pressure-transmitting portions 18 which are radially in line with the projections 17. For oversize cavities, filling pieces 37, Fig. 11, of harder material may be inserted in the slits. According to another feature of the invention, the bore or the body of the plug is provided with one or more cavities, such as 48, Fig. 16, the periphery having one or more projections 49 of equal area ; the maximum diameter of the plug is thus increased without increasing the cross-sectional area. In another form an overall reduction in diameter is compensated by a projection on the periphery. According to another feature of the invention, the plug is formed with longitudinal peripheral grooves or ribs, such as 22, Fig. 18, having a twisted configuration such that the turning effect of an expanding instrument in the initial stages of enlargement tends to enlarge the diametrical dimension by an untwisting action.

Filed: 1973-08-01
Abstract: 1369400 Radio signalling; radio receiving and transmitting circuits; transistor switching circuits MOTOROLA Inc 1 Aug 1973 [7 Sept 1972] 36643/73 Headings H3Q H3T and H4L A frequency-selecting arrangement for a transceiver comprises a first control unit 20 comprising a bi-stable circuit formed by transistors 22, 24 and a second remote control unit 120 comprising a second bi-stable circuit formed by transistors 122, 124; channel selection switches 42, 44 and 142, 144 are provided at the first and second control units respectively, being of the momentary contact type. Closure of switch 42 earths the base of transistor 22 which becomes non-conductive; transistor 24 thereby becomes conductive and the low potential at its collector renders conductive one of the oscillators 10-13, as selected by switch 34. Closure of switch 142 similarly renders transistor 122 non-conductive and transistor 124 conductive, thereby energizing a selected one of the oscillators 10-13 as chosen by switch 134. When transistor 24 is conductive it biases both transistors 122 and 124 non-conductive via diodes 140, 138 respectively; similarly when transistor 124 is conductive it biases both transistors 22 and 24 non-conductive via diodes 40, 38 respectively. Closure of either switch 44 or 144 biases transistors 24 and 124 non-conductive, whereby transistors 22, 122 become conductive, transistor 22 then energizing the oscillator 14 for an emergency channel. In addition, if the microphone at the transmitting/receiving station is hung up, it closes a switch 46 which places a negative-going pulse on the base of transistor 24, via capacitor 48 which renders it non-conductive so that the system reverts to the emergency channel: a similar switch 146 performs the same function for the remote control unit.

Abstract: 366,202. Type-bar-making machines. HART, H., 9, Kingsway, London.-(Mergenthaler Linotype Co. ; 29, Ryerson Street, Brooklyn, New York, U.S.A.) Dec. 8, 1930, No. 36951. [Class 100 (iii).] Escapements.- In machines having a number of magazines pivotally mounted at their upper ends, means are provided for adjusting the position of the escapement actuating - levers, in order to compensate for the varying positions occupied by the escapement actuating - slides when different magazines are in operative position. The escapements C of each magazine are operated through their actuating- slides C<1> by a single series of levers D, which are centrally pivoted and are connected at their lower ends by angle-levers E to the escapement-reeds F. When the lower magazine is in operative position, its escapement actuating-slides C<1> occupy a slightly more forward position than do those of the upper magazine, so that the upper ends of the levers D must be given a corresponding forward movement. For this purpose, the levers D are mounted in a rocking frame H, pivotally mounted at the point at which the lever D engages the,levers E, so that movement of the frame does not alter the extent of movement of the levers D. When the upper magazine is in use, the frame H is maintained in its rearward position by engagement of the lower magazine with an arm H<2> on the frame. When the lower magazine is brought into use, the arm H<2> is released, and the frame H is rocked forwards against a stop H<4> by its weight or by a spring. Specification 184,970, [Class 100 (iii), Type making &c.], is referred to.

Abstract: 1,139,142. Acoustic measurement of physical properties. N.B. AGDUR and P. WEISSGLAS. 22 Aug., 1966 [3 Sept., 1965], No. 37595/66. Heading H4D. [Also in Division G1] In a system for measuring the weight per unit surface area of sheet material a transducer energized by spaced electrical pulses of predetermined amplitude and duration vibrates the material and the vibration amplitude is determined. In the Fig. 1 embodiment sheet material 10 is vibrated by acoustic pulses transmitted by transducer 11 and reflected from surface 35. The output of receiving transducer 13 is passed to amplitude-measuring circuits 34, 17 via gate 33 which blocks that output corresponding to energy received directly from transducer 11. The input energy to transducer 11 may be held constant, or a probe which senses the vibration amplitude of transducer 11 may be used to keep that amplitude constant. In alternative embodiments direct transmission of radiated acoustic energy between transducers 11 and 13 is prevented by mounting them (a) in separate acoustically-insulated enclosures on one side of material 10 (Fig. 2, not shown), or (b) in separate baffled enclosures one on each side of material 10 (Fig. 9, not shown), or (c) coaxially in a common enclosure, with acoustic insulation between the transducers (Fig. 3, not shown). Embodiments employing electromechanical transducers directly coupled to material 10 as the receiving transducer (Fig. 4, not shown), or as the transmitting transducer (Figs. 7 and 8, not shown) are described. In further embodiments a receiving transducer disposed on each side of material 10 and coupled to respective inputs of a differential amplifier (71) are used (Fig. 5), or the vibration of material 10 is measured by an optical interferometer (not shown).
