Abstract: 628,414. Engraving-machines. FRANCIS, E. L. M. April 23, 1947, No. 10907. [A Specification was laid open to inspection under Sect. 91 of the Acts, April 23, 1947.] [Class 100 (ii)] An engraving-tool is freely and rotatably mounted in a support, and a guide member is secured to the support and partly or entirely surrounds the tool at a slight distance from its point so as to abut during engraving against the work-piece and guide the tool, thereby determining the depth of the engraving pro- - duced. An engraving-machine comprises a pantograph mechanism 18, Fig. 1, carrying an engraving tool 22, Figs. 1 and 4, and a stylus 35 engaging a pattern 36 and pivoted to the machine frame 10 on a horizontal shaft 13. The mechanism is spring-urged upwards and is depressed for operation by a button 74. Two adjustable pivots 20, 76, of different diameters are provided on the pivotable frame 14 to enable two alternate pantographs to be attached having different reduction ratios. The pantographs may be removable or turnable out of the way when not in use. The tool assembly comprises a tubular support 45 secured to the pantograph, and freely rotatable therein a holder 48 carrying the needle 49 and rotatable by means of a pulley 59 and belt 65 from an electric motor 62 pivoted on the machine frame at 63 so as to be able to move with the pantograph, a spring 68 keeping the belt tensioned. A conical guide 46 partly or entirely surrounds the tool and has an annular surface 47 to contact the work and limit the depth of engraving. The guide 46 is secured to the support 45 by screws 46<SP>1</SP>, the screw-holes in the guide being larger than the screws to permit of lateral adjustment. The needle 49 has a member 52 axially slidable on it and adjustable axially by a set screw 55 and having a threaded portion 53 screwing into the holder 48 so that the point of the needle protrudes behond the surface 47 a desired amount.

Abstract: 1310336 Multiplex pulse signalling SIEMENS AG 23 April 1971 [24 April 1970] 10953/71 Heading H4L In a time division multiple access communication system in which means are provided at each ground station for ensuring that the signal bursts from each station are correctly phased to appear in their allotted time positions at a satellite relay station, one of the stations acting as a reference station and providing a reference burst forming the start of a pulse pattern frame in which the bursts from the other stations are arranged in time division, a channel counter KZ1 is started by each pulse E2 derived from the incoming signal and representing the star of a frame and each time it reaches a count displayed by a backwards-forwards counter V-RS1 a comparator V1 supplies a pulse to a phase discriminator PD preferably of digital type. The desired phase of the local burst in relation to the reference burst is stored in the counter V-RS1. Pulses E1 derived from the received signal and representing the phase of the local burst as returned by the satellite repeater are also supplied to the phase discriminator PD, lack of coincidence producing an error signal which is averaged at FE over a large number of frames and supplied to a phase-correcting store PS. A bit-frequency generator TC supplies timing signals to appropriate parts of the equipment via terminal TO and via a frequency converter FK produces pulses at channel frequency supplied to an output T1. The pulses at channel frequency are further divided at FR to produce pulses at the repetition frequency which start a channel counter KZ2 and via output BS start the transmission of the station burst. The channel counter KZ2 co-operates via a comparator V2 with a backwards-forwards counter V-RS2 which stores the burst duration of the station so that a burst stop signal is provided via output Bp. The error signal from PS is supplied via gate SG which receives a blocking input from divider FR so that in the event of an error the transmitted burst phase is altered by one bit width for each pulse pattern or frame. The pulse generator TG may also be corrected via a frequency-correcting store FS. When it is desired to monitor other characteristics of the pulse pattern an internal switch in store PS is operated to remove the input to gate SG and the output of PS is supplied to control the counter V-RS1. The channel counter KZ1 is started as before by the frame start marker E2 and the signal to be monitored, e.g. space start, space end (i.e. the space allotted to the local station) start of burst from local station, first access timing marker &c. is supplied to input E1. By this means the counter V-RS1 stores the time interval separating the signal supplied to E1 and the start of the pulse pattern. The various values provided by counter V-RS1 may be supplied via circuits KO, KO<SP>1</SP>, KO<SP>11</SP> to stores SO, SO<SP>1</SP>, SO<SP>11</SP>, respectively, and utilized in unspecified manner. The various control circuits preferably use digital techniques, Fig. 6 (not shown).

Abstract: 560,346. Scaffolding. HOLTER, A. Aug. 10, 1942, Nos. 11177, 11433, 12871, 14030, 14712 and 17951. [Class 20 (ii)] [Also in Groups V and XXXIII] A method of casting a hollow article of large girth in reinforced-concrete comprises first casting a portion of the peripheral wall of the article, and then rolling or tumbling such portion to bring it into a position in which another portion of the wall can be cast alongside and adjoining the first portion. When,the second portion has been cast, the two joined portions are again rolled or tumbled into a position in which a third portion can be cast, and so on. The invention may be applied to the making of cylindrical or part-cylindrical articles, in particular marine hulls, caissons, and storage tanks and is described in connection with the casting of the centre portion of a ship's hull, the bow and stern being cast separately on a stationary base and then joined on to the centre portion. Fig. 8 shows the initial step. Pre-cast flat circular bulkheads 32 of reinforced-concrete, the reinforcements 34 of which project from the periphery thereof, are supported at spaced distances on an inclined runway. 17. Two casting forms 31, 20 are disposed beneath the bulkhead, as shown, and longitudinal reinforcements 33 are laid in position and wired or welded to the contiguous reinforcements 34. Concrete is then poured into the space between the forms and the bulkhead. Meanwhile, further reinforcements 36 are welded to the upper reinforcements 34, a travelling scaffold 26 carrying platforms 29, 30 being used for this purpose. Rollers 45 having an upward bearing prevent overturning of the scaffold. When the concrete has set, the form 20 is attached to the scaffold 26 and the latter retracted a certain distance down the runway. The partly formed tubular article is then rolled clockwise away from the fixed form 31 to the position shown in Fig. 11, jacks, cables, chains, &c. being used for this purpose. The form 20 and scaffold 26 are then used as before, a second layer of concrete 38 being cast, and so on, successive abutting layers being applied as the article rolls down the runway to the launching water. The bow and stern sections of the ship are made separately and are joined to the central section, which has been made as described above, either when the central section has been completely cast and is standing upright or at some intermediate stage, e.g. when it is upside down. Specification 560,369, [Group XXXIII], is referred to.

Title: Improvements relating to distillation apparatus
IPC: B01D3/10
Filed: 1953-04-23
Abstract: <PICT:0744844/III/1> Apparatus for fractional distillation comprising a distillation column and a reflux condenser is associated with at least one external falling-film evaporator consisting of a heated upright tube on the inner wall of which (a) distilland is distributed by wipers or brushes, and a pipe for introducing into the column the vapours generated in the evaporator.  The apparatus is particularly suitable for the fractionation of heat-sensitive liquid mixtures; in this case a film evaporator of the type described is used as reboiler for the liquid reaching the base of the column.  The vapour formed in such an evaporator has a higher concentration of the higher-boiling constituents than in the case of a circulation evaporator; and consequently the required height of column becomes less at the lower end where the danger of thermal decomposition is greater.  In the apparatus shown, the feed liquid is distributed on the inner wall of film-evaporator 1; and the vapours evolved therein are introduced into column 3 while the unevaporated liquid is collected in receiver 2.  Liquid from the base of the column flows through siphon 5 into film-evaporator 4; and the vapours evolved therein are passed to the column through pipe 6.  The liquid-residue is collected in receiver 7. The vapours leaving the head of the column are condensed in cooler 8.  The condensate is separated by distributor 9 into product-distillate which is collected in receiver 10, and reflux which is returned to the column through siphon 11.  The system may be evacuated through pipe 12.
