Title: Method of and device for signalling in pulse communication system
IPC: H04J3/12
Filed: 1952-04-10
Abstract: 697,280. Pulse signalling. COMPAGNIE INDUSTRIELLE DES TELEPHONES. April 10, 1952 [April 17, 1951], No. 9315/52. Class 40 (v). ' For calling on a pulse channel using a pulse recurrence frequency of F, the recurrence frequency is reduced to F/2 by providing a pulse generator producing pulses of alternate polarity at frequency F and an arrangement of rectifiers which rectify the pulses for communication purposes and suppress alternate pulses when switched by a calling relay. In one embodiment, a master oscillator 1, produces a sine wave of frequency F/2 which is squared in circuit 2 and differentiated in circuit 3 to produce alternate positive and negative pulses. Each channel circuit is supplied with these pulses from an individual tapping on delay line 4 and for normal communication they are passed through transformer 6 to a full-wave rectifier 7 to produce a train of positive pulses of recurrence frequency F which is applied to the modulator 9. In circuit 9 the pulses are modulated in amplitude, duration, &c., by voice currents from line 12 through hybrid transformer 11, the modulated pulses being obtained from terminals 10. Signalling currents in line 12, rectified in circuit 14, operate relay 8 to change the circuit of rectifier 7 so that the negative input pulses are removed and positive pulses of recurrence frequency F/2 are fed to the terminals 10 to constitute the signalling condition. A modified rectifier circuit is described, Fig. 3 (not shown). On the receiving side, incoming pulses are applied to the channel selector 15, the channel pulses being fed to a low-pass filter 16 for voice currents and a band-pass filter 17, tuned to the frequency 3F/2, connected in parallel. The filter outputs are connected in series in the grid circuit of valve 18 whose output is fed in parallel to a low-pass filter 20, passing voice currents to the line 12 through transformer 11, and a filter 21 tuned to the frequency 3F/2. When the channel is receiving the signalling pulses of recurrence frequency F/2, the substantial output from filter 21 is rectified in circuit 22 and operates relay 23. The latter connects the local source 24 of signalling current to the line 12 and opens the circuit feeding relay 8.

Title: A new or improved method of and means for manufacturing tiles, slabs, and other articles
IPC: B28B13/02
Filed: 1925-04-14
Abstract: 253,655. Lawton, H. (trading as Lea & Boulton), and Clarke, H. April 14, 1925. Moulding-machines with fixed mould tables; clearing apparatus; feeding; delirery; dies; lubricating.-A moulding-machine of the type in which a reciprocating feed-box delivers charges of clay intermittently between upper and lower pressing dies is adapted to mould tiles, slabs, and similar thin articles on their edges, so that the faces can be burnished by being rubbed against the walls of the die during the process of ejection. The invention is illustrated as applied to a machine for moulding several mosaic tiles simultaneously. A lower die b shown in Figs. 6 and 7 receives the charge of clay dust in the recesses b<3> and co-operates with the serrated edge t<2> of the upper die T, Fig. 4. Each recess b<3> forms a complete tile. The upper die is lowered by a press screw (not shown), and the lower die is raised by a treadle (not shown) against the. action of a weight. The sliding feed-table d, carrying the hopper f, is reciprocated by the lever Z between the position illustrated, and that in which the front edge of the plate k leads directly to the slot m in the die-box. The hopper is mounted on bracket s and pressed downwards by springs r<2> so that it rests against a roller h. A hinged door f<3> is fixed in such a position that clay dust escapes from the opening f<1> when the roller is rotated anticlockwise, and passes over the spring-vibrated plate k to the slot m. A pivoted pawl-carrying plate v co-operates with the fixed studs w, x to transmit the necessary rotation to the roller shaft. The table d also carries a spring-mounted levelling-scraper p for removing excess material delivered to the dies, and an ejecting and lubricating comb g which registers with the apertures b<3> in the lower die to push the finished tiles laterally from the die, and is furnished with a slot containing felt g<5> soaked in paraffin to lubricate the recesses in the lower die after the ejecting process.

Title: Improvements in or relating to calculating apparatus
IPC: G06F7/498
Filed: 1944-05-19
Abstract: 593,683. Calculating apparatus. NATIONAL CASH REGISTER CO. May 19, 1944, No. 9734. Convention date, July 18, 1940. [Class 106 (i)] In a calculating machine comprising a source of electric impulses connected to a totalizer formed of a ring of digit-representing electron tubes, an amplifying tube of the electricdischarge gas-filled type is situated between the impulse source and the totalizer, the amplifying tube having a grid normally biassed to prevent conduction, but to permit discharge on receipt of an impulse, the circuits associated with the cathode of the tube thereupon producing an oscillatory rise in cathode potential to extinguish the tube. The embodiment described is similar to that shown in Specification 593,682, the means for amplifying the impulses passing from the impulse source or emitter to the totalizer being, however, different. Moreover, in the present embodiment, a resistance 'is placed in series with the condenser in each circuit connecting an impulse-emitting tube to the output conductor. The amplifying means comprises a self-extinguishing gas-filled electricdischarge tube 302, Fig. 3A, for the units denomination of the totalizer. The first four and last two units-denomination digit-representing tubes 331 ... 340 of the totalizer are shown in Figs. 3A, 3c respectively. The grid 301 of the units amplifying tube 302 is biassed by connection to a point 903 between a negative source 94 and earth. The cathode 306 is connected to the negative source 94 through a resistance 907 and to earth through resistance 909 shunted by a condenser 910. Impulses received from the emitter at a terminal 300 pass to the grid 301 to cause the tube to fire and amplified impulses travel from point 906 into a feed line 321 coupled to the grids of the digit-representing tubes 331 ... 340 and of a transfer tube 341.. When the tube 301 fires, the capacity and inductance associated with its grid and cathode cause the setting up of oscillations which extinguish the tube. The tens denomination has an amplifying tube similar to the units tube 302 to receive impulses from the tens denomination of the emitter and pass them to a line similar to the feed line 321. Impulses originated by the transfer tube 341 are passed direct to the tens feed line from a cathode point 490 through a line 343.

Filed: 1943-06-18
Abstract: 588,604. Control systems for consumption apparatus. BRITISH THOMSONHOUSTON CO., Ltd. June 18, 1943, No. 9809. Convention date, June 22, 1942. [Class 38 (iv)] Switching control.- Delayed action of a con tactor 1 upon the closing of a switch 30 connected in series with the operating coil 8 of the contactor across A.C. supply rails 10, 11 is obtained by in cluding in the series circuit reversely connected gridcontrolled discharge tubes 2, 20, the grid of the former being biassed tc cut-off prior to closing the switch and the bias circuit containing a resistance-capacity combination 17, 15 which delays fall of grid potential when the switch is closed, thereby delaying conduction through the pilot tube 2. The follower tube 20 is also biassed to cut-off, until the pilot tube conducts, by the passage of current through a grid resistor 29 in a circuit'comprising also a condenser 25, a rectifier 26 and a currentlimiting resistance 27. This circuit is energized by the voltage appearing between the anode of the pilot tube and the supply rail 10. Bias on the follower tube falls to a low value when the, pilot tube conducts and the follower tube consequently conducts also. Cut-off bias for the pilot tube is obtained by connecting the resistance-capacity combination 17, 15 to a tapping on a potentiometer 12-14 across the supply rails, and connecting the cathode of the tube to the supply rail 11 through a resistance 18 so that a rectified potential difference determined by the alternating voltage between the tapping point 16 and the supply rail 11, appears across the condenser 15 when the switch 30 is open. When the switch is closed, the cathode of the pilot tube is connected to the supply rail 10 and the alternating voltage between the tapping point 16 and this supply rail is applied to the grid-cathode circuit of the tube. The positive peaks of this voltage are, however, ineffective to strike the tube until such time as is required for the voltage across the condenser 15 to fall, by discharge through the resistance 17, to a value approaching the peak voltage at the tapping point 16.

Title: Improvements in and relating to the cracking of hydrocarbons
Filed: 1929-03-27
Abstract: 331,531. BrÚgeat, J. H. March 27, 1929. Right to Patent relinquished. Hydrocarbons, cracking and distilling. - Asphaltic and other petroleum residues, low temperature carbonisation tars, acid sludges from petroleum refining, waxes and natural asphalts are converted into oils of lower boiling point by heating in a retort at 350‹-460‹C with continuous agitation, and with or without the addition of abrasive material; the level of the material in the retort is kept substantially constant. The part of the distillate boiling above 300‹ C. is returned to the retort, and the rate of distillation is preferably so regulated that the hourly products comprise 5-14 per cent by weight of the contents of the retort. The pressure is preferably atmospheric but may be raised to 6 kg. per sq. cm. A small proportion of heavy oil may be added to the residues treated to lower their melting point. In an example, a residue melting at 55‹ C. was treated for 6 hrs. at 415‹ C., producing 54 per cent of oil of density 0.840, boiling below 300‹ C. 35 per cent of coke, and 8 per cent of gas. The process may be advantageously combined with an ordinary cracking plant; the heavy residues from the latter are cracked by the process described, and the products are then cracked in the usual manner. Reference has been directed by the Comptroller to Specification 160,161.

Abstract: A method and apparatus for producing a pipe transports first and second sets of chill moulds respectively along first and second endless paths, the chill moulds of each set being so transported one after another, and the endless paths being positioned such that junction faces of the respective chill moulds of the respective sets are positioned against each other in a pipe moulding zone of the endless paths. So positioning the respective chill moulds of the respective sets also defines outer surfaces thereof that are opposite the junction faces and outer surfaces that extend along edges of the junction faces at least generally in the direction of the transporting of the chill moulds. The chill moulds are locked together in the pipe moulding zone with locking surfaces respectively on the outer surfaces of the chill moulds that extend along edges of the junction faces, locking pieces having substantially the same lengths as the chill moulds and U-shaped cross sections, and locking piece transporting means for transporting first and second sets of the locking pieces one after another respectively along two locking-pipe endless paths at the same rate as the chill moulds are transported. The locking-piece endless paths are positioned in the pipe moulding zone such that insides of the U-shapes of the locking pieces engage and lock together the locking surfaces of the chill moulds in the pipe moulding zone. The outer surfaces of the chill moulds that are opposite the junction faces thereof are also pressed while the chill moulds are in the pipe moulding zone for pressing the chill moulds together in a direction perpendicular to the junction faces of the chill moulds.
