Title: Improvements relating to wet separation apparatus for the removal of dust from gas
IPC: F24F8/80
Filed: 1958-07-18
Abstract: 893,093. Separating apparatus. BERGBAUAKTIENGESELLSCHAFT NEUE HOFFNUNG. July 18, 1958 [July 18, 1957], No. 23218/58. Class 55 (2). In a wet separator for removing dust from gas, having a spray chamber which is arranged for the through flow of the gas to be freed from dust and in which the gas passes through a spray of a wash liquid and a following separating chamber which is arranged for the through flow of the stream of gas and for the separation therein of the wash liquid from the gas, the whole cross-section of the gas outlet from the separating chamber is obstructed by a filter screen, the surface or each of the surfaces of which is inclined to the horizontal and which is in the form of a member having a multiplicity of apertures for the throughflow of gas, and means are provided for the maintenance across those apertures of a film of wash liquid, the size of the apertures being so small that in use the passage of the gas necessitates local rupturing of this film and the film when so ruptured is rapidly restored. As shown, a stream of air to be freed from dust passes in succession through a pipe 1 into a blower 2, through a spray chamber 3 into a separating chamber 4. Chamber 3 s provided with nozzles which are constantly supplied by pump 5, tank 7 and pipe 8 with muddy or cloudy liquid which is superior to fresh water as a dust remover. The pressure of air containing dust laden droplets of liquid formed in chamber 3 is reduced so as to permit (1) the dust-laden droplets to fall under gravity to the bottom of chamber 4, and (2) the stream of air to pass on to condensation chamber 9. The latter is equipped with nozzles 10 from which cooled liquid emerges in order that residual moisture in the stream of air may be condensed before the air returns to atmosphere. Both floor and ceiling 12 of condensation chamber 9 consist of a narrow-mesh fabric filter of water-repellent synthetic threads. Lower fabric filter 11 distributes spray liquid and serves to bind the dust while upper fabric filter 12 collects the droplets of moisture as they form. A further fabric filter 13 is disposed below filter 11 and is sprinkled from above with muddy or cloudy liquid. Filters 11, 12, 13 are constructed in the form of a saddle roof (Fig. 2), the lower longitudinal edges being provided with gutters 16 for collection of wash liquid.

Title: String loosener and retightener
IPC: F16G11/12
Filed: 1962-06-16
Abstract: 975,536. Strainers. T. W. POND. May 8, 1963 [June 16, 1962], No. 23258/62. Heading F2G. A device adapted for loosening and retightening binding material, e.g. string securing a parcel, consists of a flat rigid plate with two parallel slots cut in from opposite edges of the plate and perpendicular to a straight line AB through a point of rotation R of the plate, the closed ends of the slots lying on this line at two points equidistant from the point of rotation, and with two holes, each close to a slot, lying in a straight line XY through the point of rotation Rand equidistant from it. When the string is taut it lies in the ends of the slots. To loosen the string, the device is rotated about the point R and the slots slide along the string until it escapes through the open ends of the slots; then the device is rotated back again so that the string is freed from its bent position and becomes slack. In a modification, Fig. 3, a converging slot is cut from the edge of the plate into each hole, through which the string can be squeezed, to obviate threading.

Abstract: 1,166,937. Extruding foamed resins. MONSANTO CHEMICALS Ltd. 3 April, 1968 [19 May, 1967], No. 23303/67. Heading B5A. [Also in Division C3] A foamed resin board is made by extruding a foamable, thermoplastic polyvinylaromatic resin through a rectangular die orifice into a zone of lower pressure defined by a pair of opposing concave surfaces maintained at a temperature below the extrusion temperature (i.e. temperature of the unfoamed resin at the die orifice) so that the resin foams in the zone, and wherein the surfaces are shaped so that they do not exert any substantial pressure on the foaming resin. The zone defining surfaces (which may initially comprise arcs of circles) reach their greatest separation where the foamed resin has fully expanded and thereafter extend parallel to each other. The parallel section may comprise movable belts, driven by contact with the foamed polymer. The die used may be as specified in British Patents 1,034,120, 1,084,000, 1,098,408 or 1,159,920, and the lower pressure zone is preferably cooled to a temperature 60-105‹ C. below that of the extrusion temperature by water cooling of concave surfaces. The maximum separation of the zone defining surfaces is preferably 1À2 to 4 times the height of the die nozzles producing a board between 1À5 and 4 inches thick of density 0À9 to 1À5 1bs. per cubic ft. Many suitable resins and blowing agents are described; the preferred resin being polystyrene.

Abstract: 1409160 Automatic exchange systems STANDARD TELEPHON UND RADIO AG 17 May 1973 [25 May 1972] 23525/73 Heading H4K An interface between a stored programme controlled processor and a switching system incorporates a last-look memory for monitoring the condition of subscribers lines and trunks connected to the switching system so that  applications to the processor are only made in respect of lines that have experienced a change in state.  As shown the system comprises a plurality of analogue telephone stations connected by concentrators A-Kz to PCM terminals T, a plurality of digital and data stations connected directly to PCM concentrators D-Kz, a plurality of conventional inter exchange trunks (LF lines) connected to PCM terminals T, and a non- blocking TDM switching assembly DE. The latter interconnects the various terminals and gives them access to registers WE and also to interfaces TE. The PCM links utilize 30 channels for intelligence signals, one channel for synch. purposes and one for control data. Each terminal is connected to an interface via a semipermanent control channel through the network. The control data consists of two bits in respect of each line or trunk terminated on a terminal and two bits for the terminal itself. The meaning attributed to the two bits may differ in dependence on the connection state of a line viz. free, busy, calling, ringing, dialling &c. If central control ZS so decrees, the whole of a control channel may be temporarily taken over in order to interrogate a particular line and to receive a detailed answer concerning the line. It is essential that the lines and trunks be scanned fairly rapidly so a condition is imposed that between each exclusive use of a control channel by central control, a scan of the lines monitored via that channel be instituted.

Abstract: 691,618. Cable sheaths. BRITISH INSULATED CALLENDER'S CABLES, Ltd. Sept. 25, 1951 [Sept. 26, 1950], No. 23593/50. Drawings to Specification. Class 36. [Also in Groups XVIII, XXV and XXVIII] An electric cable has a corrosion preventing covering comprising inner and outer layers, one layer being substantially thicker than the other and formed of an unvulcanized rubber compound containing an ultra-rapid accelerator and compounding ingredients, but no sulphur, and the other layer comprising a fabric tape carrying a rubber compound containing a large proportion of sulphur, which is applied so that its rubber coating is in close contact with the thicker rubber layer. The unvulcanized rubber compound may be applied as the inner or outer layer and may be in the form of tapes which are applied by lapping or longitudinal folding. After applying an outer covering of bitumenimpregnated hessian the cable is stored at room temperature. The sulphur from the thin layer migrates into the thicker layer and vulcanization proceeds under the influence of the accelerator. A slightly elevated temperature may be used, provided there is no deformation of the covering. Curing of the thin layer may also take place as the accelerator slowly migrates from the thick layer.

Abstract: 487,468. Vehicle spring suspensions. VOIGT, C. A. Aug. 31, 1937, No. 23768. Convention date, Sept. 9, 1936. [Classes 103 (vi), 108 (ii), and 108 (iii)] [Also in Group XXXI] In a vehicle spring-suspension or a resilient mounting for machines, motors, &c. of the kind comprising metal and rubber units in combination, the rubber unit is stressed in shear or torsion and is connected in parallel with the metal unit, means being provided for adjusting one of the units to an unloaded position whereby the proportion of load which each unit sustains may be varied. In general, the adjustment is effected so that the metallic unit takes the normal or static load entirely and the rubber unit is affected solely by the additional load. In the construction shown in Fig. 1, an annulus 4 of rubber is disposed between two sleeves 2, 3 having closed ends between which is located a helical spring 1. An indicator 5 is added to show the position at which the rubber annulus is unstressed. In Fig. 3, the wheel-carrying arm 9 of a road vehicle is adapted on displacement to stress simultaneously a rubber spring 16 in shear and a helical spring 12 in compression, the latter spring being mounted between one plate 13 on the arm 9 and an adjustable plate 14 on the vehicle frame 15. In another construction, Fig. 5, the rubber springs 23 are subjected both to shear and compressional stresses, while the load on the helical spring 22 is varied by means of an eccentric 25. Several other modifications are described, in some of which the rubber units are combined with torsional metallic springs, while in others, for example in the motor-cycle wheel suspension shown in Fig. 18, a laminated spring 57 is associated with the rubber spring, which in this case is in the form of a sleeve 66 at the pivotal end of a wheelcarrying arm 64. In all cases suitable means for adjusting one or both of the spring units is provided, and preferably an indicator, which may be located adjacent to a vehicle driver's seat, is incorporated. If desired, automatic means may be employed for adjusting the spring to its unstressed condition.
