Title: Improvements in or relating to electric discharge tubes and circuits therefor
Inventor: HOUGH GEORGE HUBERT
IPC: H03K29/00
Filed: 1950-12-12
Abstract: 736,147. Multi-stable state discharge tube circuits. STANDARD TELEPHONES & CABLES, Ltd. Dec. 7, 1951 [Dec. 12, 1950], No. 28738/51. Divided out of 736,143, [Group XL (a)]. Class 40 (6). A binary pair of gas-filled electric discharge tubes has a high input impedance so that it is triggered by pulses of a low current level the output pulses from the pair being applied to a multi-gap cold-cathode discharge tube. Fig. 1 shows a circuit comprising a trigger-pair of cold-cathode tubes CT1, CT2 to which a train of positive triggering pulses are applied at terminal P so that positive pulses appear alternately on the cathode leads L1, L2 and are applied to the multipled interleaved sets of directional cathodes of a discharge tube MCT which is of the type described in Specification 692,415, [Group XL (a)]. If initially gap 1 of tube MCT is firing a positive pulse on lead L1 causes the potential across gap 1 to decrease and simultaneously the potential on lead L2 decreases so that the potential across gap 2 increases. The discharge across gap 1 is thus extinguished and gap 2 fires subsequent pulses causing the discharge in tube MCT to step round the tube in synchronism with the pulses at P. In a modification shown in Fig. 2 the trigger pair comprises cold-cathode tube CTA, CTB having a common anode load resistor so that an input pulse train of positive-going pulses applied in common to both trigger electrode circuits is repeated as a train of negative pulses at the anode and is applied to the anode of a multi-gap counter tube MCA of which alternate cathodes are commoned and connected to resistor capacitor networks RC1, RC2. Each pulse applied to the anode extinguishes the discharge then existing across a gap and causes the next gap to fire on termination of this pulse and the previous firing gap to be extinguished.

Filed: 1960-08-19
Abstract: 922,517. Silencing gaseous currents. PITTSBURGH CORNING CORPORATION. Aug. 19, 1960 [Aug. 26, 1959], No. 28776/60. Class 7(2) A sound absorbing device, e.g. for air flow ducts such as ventilating ducts or wind tunnels, comprises one or more elongated slabs 12, 13, Fig. 1, of open-celled cellular material, such as cellular glass, having a plurality of recesses or slots 32, 33 extending into the slab from the side face thereof, the slots being of different lengths at different positions along the length of the slab. In Fig. 1 an air flow duct is formed between the slabs 12, 13 which are built up of blocks 23, Fig. 3, having slots 30, 33 originating from the edges 26, 29, being interleaved with slots 31, 32, originating from the edges 27, 28. The slots are formed by saw-cuts and they gradually increase in depth along a section, e.g. section 15, of the slab so that the ends of the slots 32 in slab 13 and 33 in slab 12 form a zig-zag line throughout the sections 15 ... 18 of slab 12 and 19 ... 22 of slab 13. The abrupt changes in length of the slots 32, 33, occur at points X which are spaced apart a distance of half the wavelength of the principal frequency in the sound to be absorbed. The slots may be inclined to the slab faces or at right angles thereto and the ends of the slots 30, 32, in slab 13 and 33, 31, in slab 12 are interleaved so that resonance set up in the slots 32, 33 in the inner faces are transmitted through the cellular material to the outer slots 30, 31. In a modification, Fig. 2a, the blocks 23a only have slots 32a, 33a, on the face forming the side of the air channel. Several slabs may be arranged parallel to one another to form several passages in an air duct. In Fig. 5 the side walls of the air channel are each formed by a pair of slabs 60, 62 and 63, 64, with air spaces 73, 75 therebetween. The slabs are formed of slotted blocks as in Fig. 1 but the two halves of each slab are slightly inclined to one another so that the air flow passage diverges slightly in one half and converges in the other. In Fig. 6 three air flow passages are formed by a pair of outer slabs 90, 103, and by inner walls consisting of pairs of slabs with air spaces 94, 100, therebetween, the slabs all being identical with those of Fig. 1. The outer sides of the slabs 90, 103, may be covered by aluminium foil 106, 107, which is perforated over part of its length and the air spaces in the inner walls are also lined with aluminium foil 104, 105. Specification 917,419 is referred to.

Abstract: 464,267. Step - by - step conveyers. LERNER, F. Nov. 3, 1936, No. 29884. Convention date, Jan. 23. [Class 78 (i)] [Also in Group XVII] Elongated articles such as cigarettes, pencils or sweets are passed either singly or in groups to a packing place by reciprocating members 3. During their passage they contact with feeling mechanism which comprises conducting rings 5 suspended on rods 6, 7. Unless such rings are raised, as shown, they complete an electric circuit when the rods are periodically-energized by mechanism synchronized with the forward movement of the pushers 3. The number of rings corresponds to the normal number of articles in a group. If each article of a group, or a single article in the case of the packing of single articles, passes properly the corresponding ring 5 is raised and the circuit which would have been made by the synchronous mechanism is broken, but if an article fails to pass, the corresponding ring remains hung on both rods and the circuit is completed by the synchronous mechanism. Completion of the circuit may give a signal or operate a clutch to stop the machine. The conducting rings may be enclosed in insulating members which contact with the articles.
