Title: Improvements in or relating to arrangements for demodulating time-phase modulated electric pulses
IPC: H03K11/00
Filed: 1946-06-12
Abstract: 613,240. Multiplex pulse signalling ; pulse modulation; valve relay sets. STANDARD TELEPHONES & CABLES, Ltd., and TREADWELL, C. G. June 12, 1946, No. 17606. [Classes 40 (v) and 40 (vi)] In an arrangement for converting time phase modulated electric pulses into duration modulated pulses in multi-channel pulse communication systems, the duration modulated pulses have leading edges which occur at fixed intervals of time, and trailing edges which occur at times determined by the signal modulation of the corresponding channel pulse. In Fig. 1, gating pulses, derived through a delay network are applied to the terminal 6. Locally generated rectangular timing pulses, of frequency NF/2 where N is the number of channels and F is the frequency of the gating pulses, are applied to the terminal 9. The combined channel pulse train is applied to the input terminals 1 and 2. The cathode bias of the valve 5 prevents operation except when a gating pulse applied to terminal 6 arrives at the same time as a timing pulse applied to the terminal 9, the gating pulse having been suitably timed by means of the delay network so as to cause the selection of pulses of one particular channel. The leading edge of each of the timing pulses raises the potential of the grid of the valve 5 near to the cut-off value. This permits the gating pulse to raise the grid potential well above the cut-off value, so that a negative output pulse is generated at the anode of the valve 5. The valve 4 is biassed so that it is unresponsive to the channel pulses applied to the terminal 1. The negative pulse generated by the anode of the valve 5 is supplied to the cathode of valve 4 and reduces the bias so that the valve will respond to the next channel pulse. A sudden reduction in potential of the anode of the valve 4 is produced, and a short negative differentiated pulse is supplied to the suppressor grid of the valve 5, thus terminating the negative output pulse originally generated by the anode of the valve 5. The rise in potential of the anode of the valve 5 at this moment is communicated to. the cathode of the valve 4 and cuts this valve off again so that both valves are in their original condition. In a modification, the anode of valve 5 may be connected to the grid of the valve 4 through a transformer, a byepass condenser then being connected in parallel with the cathode resistance 26. In this case, the transformer is connected so that a positive pulse is delivered to the control grid when the valve 5 is unblocked. In this case the elements 3 and 27 are also connected to the suppressor grid of the valve 4. In a further modification, the diode 33 is connected to the control grid of the valve 5 instead of to the suppressor grid and the timing and gating pulses are applied to the suppressor grid. In another arrangement, the output pulses are taken from the cathode of the valve 5 instead of from the anode.

Filed: 1950-07-14
Abstract: 677,680. Gelatine. KODAK, Ltd. July 14, 1950 [July 22, 1949], No. 17675/50. Class 121 The viscosity of gelatine is lowered without appreciably lowering its jelly strength by treating an aqueous dispersion of gelatine with an aqueous solution of a lower alkylamine for to 2 hours at a pH value between 8.4 and 10.5 and a temperature between 90‹F and the boiling point of water. The time range may be limited to between “ and 1 hour, the pH range to between 9.0 and 9.6 and the temperature range to between 90 and 150‹F. The alkylamine may be methylamine, dimethylamine, ethylamine or diethylamine and its concentration in the solution may be between and 5 per cent by weight. The pH values may be attained by adding an ammonium salt or a salt of the alkylamine to the dispersion. The gelatine produced may have a viscosity from 5.2 to 7.2 centipoises and a Bloom jelly strength of 225 to 290 units.

Tabulator mechanism; tabulator key actions; escapement mechanism.-A tabulator having an electromagnetic tabulator stop device operated by either a column tabulator key 5 or skipping tabulator key 13 in conjunction with a tabulator programme unit comprises a contact bar 1 attached to the frame of a typewriter and having contacts 2 at letter-space intervals and a common contact rail 3, selected contacts 2 being interconnected electrically to form said programme unit, said contacts 2 and rail 3 co-operating with a contact roller 4 or spring (not shown) attached to the carriage to establish an electrical circuit for stopping the carriage at predetermined tabulating positions. In operation to effect column tabulation depression of the column tabulator key 5 closes contact 6 on the key, whereby a relay 7 is energized to close contacts 7a, 7b and simultaneously a pull magnet 8 is also energized to close its contact 8a and release the carriage by disengaging a pawl 9 from a ratchet wheel 10 of the escapement device. When the carriage reaches a programmed tabulator-stop position the contact roller 4 establishes an electrical circuit between the contact rail 3 and a corresponding contact 2 as a result of which a relay 11 is energized whose change-over contact 11a de-energizes the pull magnet 8 whereby the pawl 9 is urged by a spring 12 into engagement with the ratchet wheel 10 to arrest the carriage. To skip some of the programmed tabulatorstop positions the key 13 is depressed and the carriage is displaced without stopping as the current to rail 3 is interrupted. On release of the key 13, however, the carriage stops at the next programmed tabulator-stop position as described above. Momentary depression of key 13 and subsequent release thereof effects column tabulation in the manner performed by key 5.

E.] June 21, 1935, No. 17876. [Class 130] In a machine for making cigarettes provided with filter plugs or mouthpieces in which aligned plugs and cigarettes are delivered axially on to a web of wrapping material which is folded and secured around them to form a continuous rod which is severed by cutting mechanism, means are provided to engage with the end faces of the plugs or cigarettes after they have been delivered to the wrapping material to position them with respect to the cutting mechanism. Double length cigarettes are fed one at a time from a hopper 6 on to an endless belt 11 and spaces, into which double-length plugs are fed from a hopper 13, are formed by a rotating member 12. The cigarettes and plugs are delivered over a fluted bridgepiece 16 or between side guides on to a web 17 of wrapping material, by pushers 14 on a conveyer 15 running at the same speed as the belt 11 and faster than the web 17. Rollers 20 running on a guide rail 19 move the pushers 14 away from the cigarettes and plugs just before they are engaged by spring-urged fingers 23 which pass through apertures 22 in a drum 21, and position the cigarettes and plugs on the web 17. The fingers are pivoted on a flange within the drum and contact with a stationary cam 24 which is so shaped that the driving face of each finger remains parallel with the end face of a cigarette or plug so long as it is in engagement therewith. After the cigarettes and plugs have been positioned on the web, the loaded web is moved by an endless band 25 through folding mechanism 26 to pasting mechanism which supplies sufficient adhesive to secure the overlapping edges of the web and to secure the plugs and cigarettes to the web. The web may be supplied with cork tips by tipping mechanism 34. In modified constructions, (a) the adhesive is applied to the web before the cigarettes and plugs are located on it, and (b) the cigarettes and plugs are not secured to the web ; a rotating knife 33, Fig. 3, slits the wrappers of the cigarettes and the plugs before they are enclosed in the wrapping web 17. A plug may be constituted by a filter, by a mouthpiece which may be empty or entirely or partly filled with filtering or flavouring material, by a composite mouthpiece formed in part by a length of wrapped cigarette rod and in part by a length of filtering or flavouring material or by a mouthpiece comprising a length of tobacco filler in a wrapper, the tobacco being of a different kind from that in a cigarette. Specifications 430,742 and 430,817 are referred to. According to the Provisional Specification, the plugs and cigarettes may be placed on a porous band on which lengths of filter tip material are held at spaced intervals by suction. The cigarettes and stubs may be aligned by a plunger.
