Title: Container having a built-in emptying device for pulverulent material or the like
IPC: B65D88/62
Filed: 1956-12-11
Abstract: 813,003. Discharging materials from vehicl ( bodies. HERMANNS, W. Dec. 11, 1956 [Jan. 19, 1956], No. 37853/56. Class 78 (4). A flexible member 11 normally lies against the walls of a container 1, but is raised to the position shown in broken lines 14 when material s to be discharged to an outlet 3. In the construction illustrated the flexible member coinprises a bag receiving compressed air through a conduit 13, but the member may comprise a diaphragm secured to the wall and floor. Inclined bars fixed on the walls of the container support air-permeable tubes 8 supplied with compressed air to facilitate flow of the material lodged in the troughs formed between the outer surface of the flexible member 14, when distended, and the adjacent walls of the container. In an alternative construction (Fig. 5, not shown), two flexible members are disposed one on either side of a central opening in the container so that when inflated they form between them a trough directing material to the central outlet. The member 11 may be air-permeable and preferably includes a relief valve 24.

Title: Strip Material Winder Device
IPC: G03B17/26
Filed: 1966-08-25
Abstract: 1,156,305. Film cartridges. EASTMAN KODAK CO. Aug. 25, 1966 [Aug. 25, 1965], No. 38127/66. Headings G2A and G2E. A cartridge casing 9 for receiving exposed film has a central rotatable core 23 on which the film is to be wound, and an entrance opening 11 through which the film is received. A bellcrank assembly 13 (see also Fig. 4 not shown), pivoting on a pin 17, is spring-urged to hold a roller 19 against a wall of opening 11 so as to form a light-tight closure. When the cartridge is inserted into a specially-designed complementary recess in a film unit or camera, a projection 16 therein engages the ends 15 of the bellcranks 13, and pivots the assembly so as to open the entrance 11. On entry, the leading end of the film is guided between a resilient guide 21 and a further guide 27 so as to be frictionally engaged by the surface 24 of core 23. This is rotated by a magnetic coupling (39) from a motor (M, see Fig. 1 not shown). When the film is wrapped round the core a sufficient number of times to assure a firm grip thereon, the guide 27 can be retracted from the position shown in full lines to the position shown in dashed lines. This is effected by tab members 28, 29 attached to the guide 27, and which are pulled together towards an abutment 37. The device is suitable for the winding of perforated or non-perforated film, or any other kind of strip material, e.g. magnetic tape.

Title: Olefinic copolymers
IPC: C08F210/00
Filed: 1963-09-27
Abstract: Linear copolymers soluble in boiling aliphatic solvents, and containing units derived from one or more di- or polyalkenyl-benzenes, ethylene, and one or more aliphatic alpha-olefins containing 3 to 8 carbon atoms, are made by copolymerizing a mixture of the monomers in the presence of a catalyst comprising the reaction product of a vanadium compound and a halogen-containing organometallic aluminium or beryllium compound, or complex with a Lewis' base, such as an ether, thioether, tert.amine, or trisubstituted phosphine.  Specified di- or polyalkenylbenzenes are diallylbenzenes, allyl-buten-2-yl-benzenes, allyl-buten-3-yl-benzenes, and allyl-hexen-5-yl-benzenes.  The polymerization is preferably effected in a hydrocarbon or halogenated hydrocarbon solvent. The catalyst may be prepared and the polymerization effected at temperatures from - 80 DEG  to 125 DEG C. Exemplified catalysts are (C2H5)2AlCl and VCl4, (C2H5)2AlCl and vanadium triacetylacetonate, beryllium methyl chloride and VCl4, and (C2H5)2AlOl and VCl3-tetrahydrofuranate. The alpha-olefin may be propylene or butene-1.  The copolymers are recovered by conventional techniques, e.g. addition of methanol containing phenyl-betanaphthylamine, and treatment with HCl, water, and acetone. The copolymers may be vulcanized by known methods, e.g. by heating with a composition containing 2,2-methylen-bis-(4-methyl-6-tert.-butylphenol), zinc oxide, sulphur, and mercaptobenzothiazole.

Title: Tobacco smoke filter manufacture
IPC: A24D3/02
Filed: 1958-11-27
Abstract: 865,432. Making cigarette filters. LORILLARD CO., P. Nov. 27, 1958 [Jan. 3, 1958], No. 38323/58. Class 130. [Also in Group IX] Hooked pins 32, Fig. 3, mounted in helically wound strips 34, Fig. 2, of tape on a roller 30, Fig. 1, so as to pierce a moving band 17 of crimped 1 to 10 denier cellulose acetate filaments, catch and break a predetermined proportion, e.g. between 5% and 30%, of the filaments on retraction therefrom, the severed filament ends taking up heterogeneous angles relative to the band axis. The band 17 is tensioned between roller pairs 21a, 21b and 27a, 27b so as wholly or partially to remove the crimps during filament breakage, the roller 27a being driven slightly faster than the roller 21a, via a variable-speed gear 29 interposed between it and the common driving motor 23. After passing the rollers 27a, 27b, the band 17 is wholly or partly relieved of tension to allow the crimps to return and may first pass through a booth 43 where it is sprayed on both surfaces with dibutyl phthalate, triacetate, triacetin, triethyl citrate or other odourless and tasteless plasticizer, or an adhesive-like cellulose acetate, so that its filaments become tacky and adhere at their points of contact after tension relief. The booth 43 may precede the rollers 27a, 27b, when a further tensioning roller pair 44a, 44b is dispensed with. The band 17 is then passed as a bundle 17<SP>1</SP> into a machine 45 for making compressed and paperwrapped cigarette filter plugs, e.g. as in Specification 725,471, preferably having feed rolls which allow the tension on the bundle 17<SP>1</SP> to be adjusted. The band 17 is formed from a bundle 14 by an air blast from a perforated table 15 and by rollers 18a, 18b, freely rotatable apart from being braked by an oil pump 25 or friction brake. The rollers 18a, 18b and 21a, 21b, respectively, have intermeshing axial corrugations, or the roller 21b may be rubbersurfaced. The rollers 27a, 27b may be similarly corrugated, or the roller 27b or both rollers may be rubber-surfaced. The rollers 21b, 27b are held against stops by springs 24, 24b yielding on overload. Fixed guides 26, 31 are provided. The roller 30 is freely rotatable apart from being braked by an oil pump 35 or friction brake; and the angle its axis makes with the band axis is adjustable by moving one bearing 38, Fig. 2, along a slot 41 about the other bearing 36 as a pivot, so varying the effectiveness of the pins 33; alternatively or additionally the helical pitch of the strips 34 may be altered. The roller 30 may be mounted above the band 17 or may be followed by a like roller 30 above or below the band or by a roller with straight pins 32. U.S.A. Specification 2,794,239 also is referred to.

Title: Improvements in or relating to signalling conductors
IPC: H01B11/14
Filed: 1928-12-31
Abstract: 314,510. Electrical Research Products, Inc., (Assignees of Martell, C.). June 29, 1928, [Convention date]. Continuously loaded cables.-A signalling cable is formed with a layer of stearine pitch between the conducting core and the loading material, the pitch being applied either by vacuum impregnation or by a combination of vacuum and pressure impregnation. The loaded conductor is passed through hot stearine pitch under less than atmospheric pressure, and may be passed to a second container where stearine pitch is forced into the core under a. pressure greater than atmospheric pressure. The core is then covered with guttapercha by extrusion. In the construction shown, a copper wire 10 is wound with helical copper strip 11, and loading material 12 applied as a closely wound tape. A layer 13 of stearine pitch forms a cushion between the material 12 and the conducting core. Guttapercha insulation 14 completes the cable. For the loading material, a magnetic nickel-iron alloy containing more than 25 per cent of nickel is preferably used, an example given being 78¢ per cent of nickel, the remainder being principally iron. Specifications 184,782, 211,095, and 250,477 are referred to.

Title: Electronic switching matrix
IPC: H01L27/102
Filed: 1962-10-12
Abstract: 960,960. Automatic exchange systems. STANDARD TELEPHONES & CABLES Ltd. Oct. 12, 1962 [Oct. 16, 1961], No. 38754/62. Heading H4K. In an exchange system comprising a plurality of cascaded cross-point matrices through which a connection between a marked inlet and a marked outlet of the system is to be set up, means responsive to the markings initiates a one at a time search of each of a plurality of self-seeking paths between the marked points and means responsive to the completion of a first one of said paths terminates the search and holds the completed path. The matrices are composed of PNPN diodes and a discussion on the effects of using marking pulses having wave fronts of different rise times on diodes whose striking voltages fall within various tolerance ranges, thereby giving rise to the possibility of a false connection, is given in the Specification. It is also suggested that the application of a standing bias voltage equal to half the firing voltage causes a substantial reduction in the capacitance of such diodes and hence reduces cross-talk. On initiation of a call, a negative-going marking pulse P having a relatively slowly-" rising " wave front is applied via a resistor Rs in his line circuit to the corresponding row of diodes D1 to D3 in a primary matrix of such diodes. Eventually the diode having the lowest firing potential, D1 say, fires and causes the potential on capacitor C1 to fall relative to its initial potential of +E, whereby one of the diodes D4 to D6 (which have lower firing potentials than D1 to D3) in a row of an intermediate matrix connected to the column B1, eventually fires. Assuming this diode to be D4, the resultant fall of potential on C2 causes a diode D7, marked by earth potential over closed contact 32 in the secondary matrix, to fire and so complete the path between subscriber 30 and the allotted one of the links 24, this path then being held by the potential - E. Assuming, however, that D4 does not have access to the link, then because the potential on C2 rapidly approaches that on C1, diode D4 tends to cut-off and remains cut-off at least for the duration of the marking pulse. However, the potential on C1 continues to fall (since the pulse continues) so that the diode having the next lowest firing potential, e.g. D5, fires and in so doing may or may not complete a path to the marked link. Similarly, all the other diodes D6 (&c.) may fire in turn without completing the path, whereafter, due to the equalization of potential on C1 and C, diode D1 cuts-off. Again, the diode in the primary matrix having the next lowest firing potential, e.g. D2, fires and a similar sequence of events occurs until a complete path to the link is found. The length of the rising wave front of pulse P is sufficient to ensure that all the possible paths through the matrices are tested before the pulse reaches its peak. Dialled digits are then stored in the link and a similar process is used to connect the links to the wanted subscriber. Specification 813,862 and 953,895 are referred to.

Abstract: 929,120. Exciting dynamo-electric machines. SELECTRA Ltd. Nov. 27, 1959 [Dec. 5, 1958], No. 39355/58. Class 35. Excitation of an A.C. or D.C. generator is initiated by a permanent magnet generator permanently connected through rectifiers to the field winding of the main machine in series or parallel with the normal excitation means. In a single phase form shown, the field winding 20 of a generator 10 is fed from the permanent magnet generator 15, 16, and also by the conventional excitation system, e.g. compound, at leads 11, 12. The reactance of the exciter winding 16 may be matched at the rated speed by a series condenser 17 so that the exciter voltage is independent of the current taken by the main field winding. The condenser may be connected through a series transformer for voltage matching. Alternatively the exciter may be compounded. The exciter voltage is lower than the normal excitation voltage so that once this has been initiated the rectifier 18 prevents further flow of current from the exciter. The exciter may be driven directly or through increasing gearing from the main machine or it may be separately driven. A three-phase form is described in which the exciter windings are connected in series with condensers and are connected to the rectifier through a tapped variable ratio transformer or matching impedances. The full-wave rectifier may be replaced by a halfwave rectifier and smoothing condenser. In this case two field windings are used, the normal excitation circuit feeding one of them and the initiating circuit feeding both in series. The main machine 10 may be an inductor alternator exciting a large power generator. Specifications 719,212 and 719,267 are referred to.
