Abstract: 1,205,435. Cigarette-making machines. BRITISH-AMERICAN TOBACCO CO. Ltd. 30 May, 1968 [6 June, 1967], No. 25988/67. Heading A2C. In an apparatus for uniting mouthpieces 2 and tobacco rods 1, the aligned assembled components are united by a strip 4, by rolling the assembly in contact, at three circumferentially spaced regions, with the surfaces of three rollers 10, 16, 17 all rotating in the same direction and driven at the same peripheral speed, one roller 17 being located in the bite between the other two. The apparatus is particularly suitable for uniting "cigarlettes" to mouthpieces having an open cylindrical part, optionally including a filter, and a flattened mouthpiece bit. The components 1, 2 are fed in pairs from either side 5, 6 of a partitioned hopper 7 into grooves 9 of the roller 10 on which they are abutted by two cams 15 sited at either end of the roller 10 (one only is shown), while being transported to the roling region. The strips 4 are cut off a paper band 20 coated with a heat sensitive adhesive on one side, and held by suction on the roller 16, in conventional manner, and the adhesive is activated by means of electrical heating cartridges 28 within the drum 16. At the rolling station, an assembly 1, 2 in a groove 9 drops on to the surface of the roller 16 just after a groove 26 in the latter has passed, but just before a strip 4 arrives, and the rod 1 and mouthpiece 2 are brought into final aligned abutment by an air jet 31 that pushes the two components in line against a stop 30 that extends from the cam 15. After rolling, the united assembly falls into a groove 26 of the drum 16 and is delivered to a collection means 27. In another embodiment a conventional adhesive applicator for the paper uniting band is provided, and the top half of the apparatus, including the rollers 10, 17, is hinged to allow adjustment for cigarlettes of other diameters. The axial setting of the cams may be adjustable to accommodate different length assemblies. The rollers 10, 17 may be rubber-covered.

W., 155, Clifton Road, both in Rugby. Sept. 10, 1934, No. 25997. [Classes 75 (ii), 75 (iii), and 75 (iv)] A lantern for an electric gas-discharge lamp is constructed to provide three compartments, one of which contains the lamp and is substantially unventilated, whilst the others contain the controlling devices for the lamp and are ventilated. In the form shown, the lantern comprises a sheet metal box 7 having flanges to which is screwed a plate 24 carrying two sheet metal beams 21, a plate 18, a canopy 22, and a strip metal framework 17 provided with a door 23 and glazed with plain or diffusing glass panels. The beams 21 are formed with lugs 21a which co-operate with metal rods 13, 13a, compression springs 14, and nuts 15 to adjustably support curved reflectors 9..12. The rods 13, 13a may be surrounded by tubular distance pieces. The box 7 forms a compartment 1 for an electric lamp holder 2, a resistance, a condenser, and a terminal board, whilst between the beams 21 is formed a compartment 33 containing magnetic cores 20 and coils 19, as described in Specification 429,750, [Group XL], these two compartments being ventilated by air entering by means of a removable perforated member 32, passing through an aperture 34 in the plate 24, and escaping through an aperture 35 above the plate 18. The remainder of the lantern forms a substantially closed compartment 4 for the horizontally arranged lamp 3 and the reflectors. The lamp holder 2 is supported by one or more relatively thin strips 5 of phosphor bronze secured to projections 6 on the box 7 whilst the outer end of the lamp 3 is supported by a stirrup 8 which is vertically adjustable on the reflectors 9, 10. The lantern is secured to a pole 25 by means of clamps 26, 27 and four studs 30, the clamp 26 being formed with two slots 29, Fig.4, to accommodate screws 28 on the box 7, the slots 29 permitting limited adjustment of the lantern with respect to the pole. The clamp 27 may be similarly slotted to carry a second lantern, or the clamp 27 and the studs 30 may be replaced by two U-bolts 31, Fig. 5.

Title: An improved method of and means for measuring the modulation of electric currents
IPC: G01R29/06
Filed: 1932-09-19
Abstract: 392,053. Measuring modulation. DEHN, F. B., 103, Kingsway, London.- (Elwell, C. F. and Terman, F. E.; Stanford University, California, U.S.A.) Sept. 19, 1932, No. 26059. [Class 40 (v).] Direct currents are established, proportional respectively to the crest voltage and the average voltage of a modulated wave, and the degree of, modulation is deduced from a comparison of the values of the two currents. The high-frequency currents are impressed on grids 26, 38 of thermionic detectors 27, 37 across an inductance 1. The grid-leak and condenser 28, 30 of the detector 27 have a time constant so large that the peak voltage is maintained on the grid 26. The grid-leak and condenser 40, 41 of the detector 37 have a time constant sufficiently small to enable the voltage on the grid to follow the modulating currents. The anode currents from the valves 27, 37 are passed through differential coils 34, 43 respectively. of an indicating-instrument 35. The inertia of the indicator is sufficient to integrate the effect of the varying current from the detector 37, and the instrument thus indicates the difference between the peak voltage and the average voltage of the high-frequency wave, and can be calibrated to read percentage modulation. The steadv anode current from the detectors is balanced out from the coils 34, 43 by potentiometers 47, 48. According-to modifications : crystal rectifiers are used instead of the valve detectors, Fig. 1 (not shown), the current ratio in the differential coils is made equal to the degree of modulation by reversing one of the detectors, Fig. 3 (not shown), or by winding the coil 34 in two equal and opposite sections, one of which is in series with the coil 43, while the other carries the current from the detector 27, Fig. 4 (not shown).

Abstract: 1,201,107. Regenerating carbonaceous catalysts; chemical contact apparatus. METALLGESELLSCHAFT A.G. 31 May, 1968 [6 July, 1967], No. 26351/68. Headings B1E and B1F. In a process for the oxidising regeneration of a bed of catalyst containing a carbonaceous deposit, a steam-containing regenerating gas which has an oxygen content of 1-10% is circulated through the catalyst bed, the circulation of the regenerating gas being maintained by a steam-jet ejector. Referring to the drawing, regeneration is initiated by closing valves 2, 3 and blowing steam through valve 4 to the reactor to expel residual reactants. When valve 5 is opened these residua escape through line 11. After scavenging valve 5 is throttled and valve 6 is opened. Suction produced by the ejector causes regenerating gas to circulate through the reactor. Valve 8 is opened to admit the desired quantity of air.

Suitable olefins are those containing 2-14 carbon atoms and one or more olefinic double bonds, e.g. perfluoroalkenes, perfluorocycloalkenes, perfluorocycloalkylalkenes and perfluoroarylalkenes.  The reaction may be effected in the vapour phase or in the liquid phase, optionally in the presence of gaseous or liquid diluents and/or a fluorination catalyst, e.g. silver difluoride.  The preferred temperature range is - 50 DEG  to 200 DEG C.  The perfluorinated alkane corresponding to the olefin is obtained as a side product. Examples relate to 1,2-epoxy-perfluoropropane and 1,2-epoxy - perfluoroisobutane.

[Class 83 (iii)] A lathe tool-holder comprises a body 1 having a tapered bore 9 and a cylindrical bore 12, a nut 2 rotatably mounted in the cylindrical bore and having segmental threads 16, and an inner tool-holding socket 7 having an external threaded portion 11 and a tapered portion 30 corresponding to the threads of the nut and the tapered portion of the body, respectively. A tool, such as a drill or a turning tool, is fitted in a Morse taper, or other suitable securing means, in the socket, which is then placed in the body so that its threads clear the threads 16 and so that a locating pin 6 on the socket engages a notch 19 on a ring 4 secured to the body. On rotation of the nut 2 by means of a handle 3 working in a slot 15, the threads pull a flange 10 against the end of the ring 4, leaving a small clearance between the tapered portions of the socket and body. Alternatively, the flange 10 may be omitted and the tapered portions of the socket and body may then engage. In a modification, Fig. 6, the threads 16 are formed on a cylindrical member 20 which has a shaft 21 extending through the rear of the body and carrying a handle 3 by which the member may be rotated ; a pin on the body projecting into a quadrantal slot 25 limits the rotation.
