Filed: 1971-01-13
Abstract: 1277382 Turning cigarettes end for end A SCHMERMUND 13 Jan 1971 [31 Jan 1970] 1608/71 Heading A2C [Also in Division B8] Cigarettes fed in two side-by-side rows on a drum 1, with their filter ends adjacent, arrive on a conveyor belt 21 in a single row with the filter ends all uniformly aligned. The cigarettes of one of the rows are fed to holders 4 of a drum 3. The holders are tilted by the action of a cam rail 13 so that the cigarettes are turned through 180 so as to fall into slots 14 which are in axial alignment with the positions of the corresponding holders 4 before deflection. The cigarettes are retained in the holders 4 and released at the correct instant by controlling suction applied through conduits 15, 16. The cigarettes in the other of the rows of drum 1 are fed via a drum 20 to a drum 19 where they are reunited with the reorientated cigarettes. Means (not shown) moves the re-orientated cigarettes axially so that their ends are in alignment with the ends of the non-reorientated cigarettes.

Title: Adaptive equalizer metal straps formed by interconnected links
IPC: H03H21/00
Filed: 1974-01-14
Abstract: 1452693 Adaptive transversal equalizers INTERNATIONAL BUSINESS MACHINES CORP 14 Jan 1974 [1 March 1973] 01751/74 Addition to 1424701 Heading H4R In the transversal equalizer for PSK signals as in the parent patent 1,424,701, the error signal dR/R is modified by subtracting a com-   ponent #sd# where #s is the quadrature component of the equalized signal s and d# is the phase error relative to the possible phase values of the PSK signal. The circuit of Fig. 3 receives the equalized, analogue signal s(t) from the equalizer (Fig. 1, not shown), transposes it to a higher frequency band S(t) in modulator 9 and filter 11 and passes the result to demodulators 16, 17 receiving in phase and quadrature carriers from oscillator 10 to generate s and #s. These are multiplied 21, 22 with dR/R and d# derived at 12, 13 from S(t) and suitably delayed 23, 24. The products are differenced 25 to produce the error which itself or its sign is used in the equalizer to correlate the input signal sign as in the parent patent. The circuit 13 for extracting the phase # and phase error d# as in Fig. 3 squares (27, Fig. 4, not shown) the transposed signal S(t) which is then sampled by pulses (F c ) occupying just over half the data rate period to enable the zero crossings to be detected at (33) and thereby enable AND gates (34-38) to read out the contents of a counter (39) receiving pulses at 64 times the data rate (Fr). The counter is reset after a predetermined delay (41). The three most significant digits pass to an adder (42) whilst the third also passes to a D/A converter (43) receiving the two digits remaining. The adder (42) output is combined with a path derived from the original squared S(t) to indicate whether successive zero crossings are in the same sense and therefore whether the phase change is greater or less than #. The D/A converter gives the phase error d# in two's complement code.

Abstract: 747,375. Centrifugal separators. SIMONCARVES, Ltd. Jan. 3, 1955 [Jan. 21, 1954], No. 1810/54. Class 23. The distribution of particle size in a finely divided material is determined by suspending the material in a liquid, rotating the suspension to deposit the particles in a container having particle collecting zones of different diameters, removing the liquid whilst the container is rotating, and collecting the particles from the individual zones so that the distribution may be calculated. The Figure shows parts of the container in section and separated. The container comprises a lower part 2 mounted on a drive shaft 1, and an upper part 4 having an inner stepped surface comprising particle collecting cylindrical parts 5. The container is filled with suspension through a hole 10 and rotated until the particles deposit on the parts 5. Whilst the container is still rotating the liquid is withdrawn by a pump through ducts 12, ... 14. After withdrawal of the liquid the rotation of the container is stopped and the particles removed. The parts 5 may be provided with lips to facilitate the collection of the particles. In the apparatus shown strips 16 of metal or filter paper are provided for collecting the particles, the strips being removed, dried and weighed. In a modification of the container the larger diameter steps are at the upper end of the container and in a further modification the container has a horizontal axis. Instead of the stepped construction the internal surface of the container may have a continuous slope, the particles being collected on sheet which may be cut into strip and weighed or which may be examined by an optical method in which transmitted light gives a measure of the weight of the particles deposited.

Patent GB-789265-A (GB)
Title: Improvements in or relating to isocyanates
Inventor: SMUTZ WALTER DONALD
IPC: C07C263/10
Filed: 1956-01-24
Abstract: Aromatic isocyanates are prepared by feeding an aromatic primary monoamine into a mixture of an inert organic liquid diluent and excess phosgene.  The temperature of the liquid is kept below that of the decomposition temperature of the aromatic carbamyl chloride, so formed, until all the amine has been added, when the temperature is gradually increased in order to decompose the carbamyl chloride.  The reflux of phosgene is continued throughout the process.  Preferably the aromatic primary amine is a phenyl primary monoamine such as aniline, p-chloroaniline, 3,4-dichloroaniline, m-chloroaniline, p - methylaniline, 3 - chloro - 4 - methylaniline, alpha - naphthylamine, beta - naphthylamine, 3,5-dichloro - 4 - methylaniline, p-bromoaniline, 3-chloro-4-isopropylaniline, 3-chloro-4-ethylaniline. The inert organic liquid used should preferably boil above 75 DEG  C. and be a solvent for both the amine and the phosgene reactants. Examples are benzene, toluene, xylene, tetrahydronaphthalene, mono-chlorobenzene, ortho-dichlorobenzene, anisole, nitrobenzene and 1,4-dioxane.  Preferably the proportions of phosgene and inert liquid diluent should be such that the phosgene boils between 20 DEG  and 45 DEG  C.  A phosgene reflux is maintained either by gradually increasing the temperature or by adding additional phosgene, without letting the temperature rise above the decomposition point of the carbamyl chloride.  During the amine addition the temperature may be kept between 20 DEG  and 70 DEG  C.  The temperature is then slowly increased to that of the boiling-point of the organic diluent, but not above 150 DEG  C.  The mixed phosgene and hydrogen chloride vapours leaving the reaction zone are passed into a reflux condenser, the phosgene returning to the reaction zone and the hydrogen chloride passing through uncondensed.  At least 1.05 mols. of phosgene per mol. of amine reactant should be used.  Catalysts such as dimethylaniline, or tetramethylurea may be used.  Examples are given for the preparation of p-chlorophenyl isocyanate, and 3,4-dichlorophenyl isocyanate.  Specification 372,355, [Group IV], is referred to.

Title: Improvements in and relating to electric welding apparatus
IPC: B23K11/24
Filed: 1935-01-24
Abstract: 450,939. Control systems for resistance welding ; mechanical make- and-break switches ; fusible cut-outs. TARASSOFF, W., 24, Furmannyi, and KOROVKIN, W., 3, Lesnoij, both in Moscow. Jan. 24, 1935, No. 2396. [Class 38 (iv)] [See also Groups XXXVI and XXXVII] In an electric-resistance welding-machine the duration of flow of the welding current is controlled by a fusible wire in series in the circuit which breaks the circuit a predetermined time after commencement of current flow. The wire 2 is wound off a spool 1 on to the contact arms of a rotatable commutator 4 co-operating with contact studs 10, 12 connected in series in the primary circuit of the welding-transformer. The wire is clipped on each arm between a resilient strip 5, Fig. 5, and a member 6 and the contact arms are rotated by a manually operated ratchet mechanism so that two adjacent arms contact with the studs 10, 12 for each welding operation. The commutator 4 is immersed in oil and members 14, 15 are provided which cause opening of the strip 5 and member 6 on the contact arms 4 after the wire has been fused so that the wire ends are removed. Closure of a push button 23, Fig. 6, energizes an electromagnet 24 under the control of a rotating make-and-break switch 25, 28, 281 driven by a synchronous motor 29 and adjustable so that the electromagnet 24 is energized at a predetermined instant in the cycle and closes the primary circuit of the transformer 27 at this instant. A holding circuit 34, 35 for the electromagnet is completed and is not opened until the wire fuses. A black disc 48 having a diametrical white line across it is mounted on the shaft of the synchronous motor 29 and is illuminated by a pair of discharge tubes 33 energized from the A.C. supply so that the phase position of the adjustable brushes 28, of the make-and-break switch is indicated stroboscopically by a pointer 30 mounted on the brush 28 and co-operating with the disc 48. By this means the instant in the cycle at which the circuit of the transformer is completed may be adjusted and indicated.

Abstract: 512,319. Electric room heaters. WHITAKER, A., STEVENSON. J. B., LOCKWOOD, P. W., and BARNES, N. Jan. 25, 1938, No. 2400. [Classes 39 (iii) and 126] [Also in Group XX] The reflecting surface, 1, for an electric resistance or other room heater has a configuration such that successive sections thereof in planes normal to the line ab, which is assumed to be horizontal, appear as concave curves relative to said line. A section of the reflecting surface in the median vertical plane appears as the concave curve 6, and the section by another vertical plane coincides with the left hand side of the reflector and is indicated by the line 7, whilst an intermediate vertical section is indicated at 8. The vertices of the curves comprising the vertical sections of the surface lie on the arc 2 which is in the median horizontal plane of the reflector. The focal lengths of successive sections of the reflecting surface increase as the distance from the median vertical plane increases, and the sections are so proportioned that their focal points lie on the straight line ab, which is therefore the focal line of the reflector. The reflector is of such shape as to be of concave curvature in one dimension and of convex curvature in another, and a curved back plate is fitted to the edges of the reflecting surface so as to form, together with said surface, a hollow body. A straight bar or rod-like heating element is supported with its axis disposed along or in proximity to the focal line of the reflector, and a plurality of arms is provided for this purpose, the said arms being mounted behind the reflecting surface and projecting outwardly and around the side edges thereof, and terminating in front of the surface at points intermediate the side edges. Various forms of reflecting surfaces according to the invention include one such that successive sections of the surface by planes radial with respect to a point behind it appear as parabolic curves, or the said planes may be normal to the heating element. The reflector may be other than of parabolic form. Specification 512,412 is referred to.

Title: Improvements in or relating to the production of hydrogen peroxide
Inventor: HOWE BRYAN KEITH
IPC: C01B15/023
Filed: 1959-01-22
Abstract: At least a portion of a working solution comprising an anthraquinone dissolved in a solvent therefor which has become degraded by use in the cyclic anthraquinone/anthrahydroquinone process for the production of hydrogen peroxide is regenerated by contact with a Group II metal silicate after a hydrogenation stage and before the next hydrogenation stage to which it is submitted. The metal silicate is preferably one of calcium, magnesium or zinc, or a mixture, especially magnesium trisilicate, in a pelleted or granulated form, and may be used in amount 5-10% based on the weight of the solution to be treated.  The degraded solution is regenerated at at least 75 DEG C., e.g. 85 DEG -140 DEG C. Regeneration of the solution may be effected at any stage in the cyclic process, preferably of the oxidized solution.  As a continuous process regeneration may be effected by removing a portion, e.g. 10% by volume of the working solution after oxidation and H2O2 extraction, contacting it with a bed of metal silicate and returning it to the main bulk of working solution cycling in the process prior to entry into the hydrogenator. The degree of regeneration is related to the mesh size of the silicate, the precise formula relationship being given in the Specification.  For practical purposes a particle size of not less than 360 microns is employed.  Working solutions may combine 2-ethyl, methyl, propyl, isopropyl or butyl anthraquinones in solvents such as mixtures of xylene and methyl cyclohexanol acetate. Specifications 465,070, 798,237 and 838,939 are referred to.
