Title: Method and arrangement for checking the wrapping of rod-like articles of the tobacco-processing industry
IPC: A24C5/34
Filed: 1975-09-15
Abstract: 1521315 Checking cigarettes electrically HAUNI-WERKE KORBER & CO KG 15 Sept 1975 [19 Sept 1974 26 Nov 1974] 37781/75 Heading G1N Apparatus for checking the paper wrapping of cigarettes comprises means for applying a pneumatic pressure to one end of the cigarette and measuring the pressure at the other end, which indicates the quality of the wrapping. The system includes means for continuously comparing the measured pressure with atmospheric pressure and storing the mean value of the difference for comparison with each further measured difference. As shown Figs. 2, 3, cigarettes Z are sequentially located on holders 36 of a rotating drum 35 and retained in position by suction. The drum 35 has end flanges 46a, 46b with holes 47a, 47b which are in line with the holders 36 and cooperate with slots 39a, 39b in stationary rings 41a, 41b. The end flange 46b has additional holes 48 between the holes 47b. As the drum 35 rotates pressurized air is fed from pipe 43a through each cigarette Z to exit via pipe 43b and the pressure is measured by a transducer 58 Fig. 5. Between cigarettes, atmospheric pressure is measured via holes 48. The test pressure signals are fed via a memory store 68 to a comparator 74 which receives the atmospheric pressure signals directly, the sequence being controlled by a synchronous timer 69. The difference signals are fed to a second comparator 83 whose other input is the mean value of this difference as determined in unit 64 and used to set a potentiometer 91. The output from comparator 83 is averaged at 64 and compared with pre-set maximum and minimum tolerance values set in at 96, 97. If the mean value gradually varies by more than the tolerances a motor 89 resets potentiometer 91 accordingly. The output from comparator 83 is also compared at 101 with a pre-set reference value on potentiometer 102. If the difference is excessive, a signal is sent via shift register 103 to remove the faulty cigarette producing this difference value. The excessive difference signal is also prevented from reading the averaging member 64.

Title: A process for preparing higher aliphatic alcohols
IPC: C07C29/149
Filed: 1930-12-18
Abstract: Higher aliphatic alcohols, containing at least six carbon atoms, are produced by reduction of esters of the corresponding acids by hydrogen under pressure at 300-400 DEG  C. in presence of a catalyst comprising finely divided copper.  The copper may be used on a carrier such as kieselguhr, and the pressure may be 100-200 atmospheres.  An example describes the production of lauryl alcohol from the ethyl ester of lauric acid at 350 DEG  C.  Instead of ethyl laurate, the mixture obtained by esterifying with ethyl alcohol or other lower aliphatic alcohol the mixed fatty acids from coco nut oil, may be employed.  The glyceryl esters of the higher fatty acids may also be used.  The products may be used in the textile finishing industry; in particular they are readily sulphonated, since their non-alcoholic contents are almost entirely capable of sulphonation and may include unsaturated compounds.

Title: Improvements in or relating to programming systems
Inventor: FRANKLIN DONALD PETER
IPC: B23Q15/00
Filed: 1957-12-11
Abstract: 912,658. Programmed electric-control systems. ELECTRIC & MUSICAL INDUSTRIES Ltd. March 9, 1959 [Dec. 11, 1957], No. 38462/57. Class 38 (6). An analogue of a conveyer system is provided so as to check that a particular punched or magnetic tape programme prepared to control the routing of motor-car bodies on the real conveyer system (as described in Specification 814,547) will not cause some section of the conveyer to be overloaded. It is assumed that of the car bodies on a main conveyer A, some are to be routed to a branch conveyer B for, e.g. single-tone paint spraying, whilst the remainder are to be routed to a branch conveyer C for, e.g. two-tone paint spraying. Because the two spraying processes take different times, conveyer B can effectively handle, e.g. four bodies per minute, and conveyer C three bodies per minute. Temporary stores are provided on each branch conveyer so that bodies can wait their turn for painting. A master programme tape is prepared which carries coded information in the correct sequence to identify each body on the main conveyer A together with routing instructions according to a desired production schedule. This tape T1 will control the conveyers as disclosed in Specification 814,547, but for checking, it is fed to a reader R1, which provides an output pulse to a differential counter 6 each time a body for conveyer B is identified. The master tape T1 is advanced one " body " at a time by every second pulse from a pulse generator 7. The alternate pulses from generator 7 advance a tape T2 through a reader R2. The tape T2 carries three rows of perforations. The first row consists of evenly-spaced perforations, one per car body on conveyer A, the spacing being proportional to the rate of feed along the main conveyer A. This row synchronizes tape T2 with tape T1. The other two rows represent the bodies on conveyers B and C, their spacing being proportional to their respective rates of feed. Each time a body is read from tape T1, a differential counter 6 is advanced in one sense, and each time a body on conveyer B is read from tape T2 the counter 6 is advanced in the other sense. The final state of the counter, which represents the storage capacity required on conveyer B is indicated by lamps 8. If the known capacity is exceeded, an error signal may be punched on a tape T3. The tape T3 can also be used to provide programme tapes for subsidiary conveyers in a manner similar to that disclosed in Specification 814,547. In a second embodiment, Fig. 3 (not shown), the tape T2 is replaced by four pairs of stepping switches with connections at appropriate contacts to represent the rates of feed on the B and C conveyers, the switches being stepped alternately by pulses from the tape T1, and via a system of interlocking relays providing the output pulses for the differential counter. It is stated that the system may be used to compare any sort of programme with the capability or capacity of means or personnel for carrying out the programme.

Title: Remote movement detector
IPC: G01H9/00
Filed: 1974-09-03
Abstract: 1513249 Controlling light; DECCA Ltd 25 Nov 1975 [3 Sept 1974] 38501/74 Heading G2F [Also in Divisions G1 and H4] In a remote movement detector, e.g. a vibration detector, in which a coherent light beam is directed at a remote target and light which is reflected from the target is mixed with light that is not so reflected to obtain a Doppler signal representing the movement of the target, a detector is provided which automatically counteracts variations, due to surface irregularities in the target, of the Doppler signal. In a particular embodiment, a coherent light beam from a laser 2 is split by a polarization beamsplitter 3 into two components 4, 5 the former being directed at a static mirror 6 and the latter by way of a path-length modulator 8 and an optical system 9 at a vibrating target 1. The two components 4, 5 are reflected back to the splitter 3 where they are recombined and directed to a photodetector 7. The path-length modulator 8 results in the Doppler frequency obtained in the output of the photo-detector 7 varying about a non-zero frequency enabling movement of the target 1 towards the source 2 to be differentiated from movement away from the source. The Doppler signal is amplified at 13 and demodulated at 14 so as to provide at an output terminal 15 a signal of which the amplitude varies in accordance with the variation of the velocity of the target 1.  The optical system 9 comprises a telescope formed of a concave lens 10, an intermediate convex lens 11 and an objective planoconvex lens 12, the lens 10 being mounted within a short ferromagnetic cylinder 16 carried on a cantilever 17 and movable under the influence of an orthogonal pair of coils 19, 20 fed with cyclically varying electric current from respective power amplifiers 21, 22 at a frequency of, for example, 150Hz. The coils 19, 20 are preferably fed in quadrature so that the light component 5 moves over the target 1 in a conical scan. The Doppler signal is demodulated at 23 and amplified by a tuned amplifier 24 to remove harmonics of the scanning frequency and other unwanted signals and then fed to one input of each of two phase-sensitive detectors 25, 26. To the other inputs are fed the outputs from an oscillator 27 displaced in phase by 90 degrees. The output of each of the detectors 25, 26 is a D.C. signal which is + or - according as the respective input signals are in-phase or anti-phase respectively. The output is, in either case, an error signal which is used to bias the projected beam towards a position which yields a maximum return signal. The two D.C. signals are fed through respective stability correction circuits 30, 31. The two power amplifiers 21, 22 receive through input resistors 33, 32 the outputs of the oscillator 27 directly to which are added the D.C. error signals from the phase-sensitive detectors 25, 26.
