[Also in Division Dl] Elastic tape 2 is secured to a textile article 1 made of natural or synthetic fibres by spot welding the ends of the tape 2 to the article whilst the tape is held under tension, a component of thermoplastic material being incorporated in each weld. As shown, a cutout 1, e.g. of baby pants made of cellulose fibres, in positioned on a base-plate 4. Elastic tapes 2 are positioned parallel to the upper and lower edges of the cutout and are held taut at their ends by clamping or holding devices (not shown). The tapes 2 are preferably made of or coated with thermoplastic material, Alternatively, a thread of thermoplastic material may be added to or twined with the elastic tape. The ends of the tapes are spot welded at 3 to the cutout 1 by heat and pressure. Additional spot welded joints, 3<SP>1</SP> may be provided between the joints 3. To secure elastic tapes along curved lines, e.g. around the leg openings of the pants, the plate 4 is provided with needles or pins 5 which either penetrate the cutout 1 or abut the edge thereof. If the tapes 2 are to be enclosed by subsequent folding over of the edge of the cutout, cuts 6, in the inner vertex of each of which a pin 5 is located, are formed in the cutout, Fig. 3. The tapes 2 are laid around the pins 5 and held under at their ends whilst welding takes place. Preferably, two spot welds 3<SP>1</SP> are formed at each cut 6. The welding tool is provided with a number of welding devices so that all the spot welds 3, 3<SP>1</SP> are formed simultaneously. After the tapes 2 have been secured a pattern template (7), Fig. 2 (not shown), is applied so that its lateral edges coincide with fold lines a, b, Fig. 1. End parts 1<SP>1</SP> are folded inwards about the lines a and the lower part of the cutout is folded upwards about the line b and the superimposed parts in the region of the parts 1<SP>1</SP> are welded together.

Title: Circuitry for suppressing spurious electric signals
IPC: G06F3/06
Filed: 1957-02-06
Abstract: 808,037. Pulse circuits. NATIONAL CASH REGISTER CO. Feb. 6, 1957 [Feb. 23, 1956], No. 4042/57. Class 40 (6). Fig. 1 shows a circuit for amplifying shaping and gating the signals sent by the reading-heads associated with the channels on a rotating magnetic drum 100. As the drum 100 revolves the substantially square magnetic saturation pattern 129, Fig. 2, of binary digits 1 and 0 recorded on channel 1 and represented at 138, Fig. 2, induces a waveform 130, Fig. 2, at head 102 in which associated with e + and e - pulses corresponding to the leading and trailing edges of waveform 138 unwanted overshoot is also present. The play-back coil 104 is loaded by resistor 108 so that the oscillatory pulses 131, Fig. 2, are quickly damped out. The signal is amplified in negative feedback amplifier stage 133 and applied directly to cathode follower stage 134 to produce the waveform shown at 140, Fig. 2. This signal is inverted by transformer 110 and clamped by diodes 113, 114, the potentiometer 137 being set at a +95 volts level so that a waveform 141, Fig. 2, is produced on line 112 and waveform 142 on line 111. The inversion and clamping action removes the " ringing " from waveforms 141 and 142, Fig. 2, as are also extraneous low-level pulses originating as noise in the system. Waveforms 141, 142, Fig. 2, are fed as input to AND circuits 116, 115, the other input to each being the channel select function derived from the diode matrix 117. Thus if matrix 117 is arranged for the selection of information in channel 0 pulses e+ and e - are passed by the gate and appear on lines 121 and 120 respectively. The voltages on the lines are limited to a maximum value equal to that of the channel select function, i.e. signals above + 125 volts will not appear on the lines, as shown at 164, 165, Fig. 2. The outputs from AND circuits 116 and 115 corresponding to all of the heads 101 are fed to OR circuits 123 and 122 respectively, thus all leading edge pulses e+ are received by OR circuit 123 and trailing edge pulses e - by circuit 122. Only one of the pairs of signals received by circuits 123, 122 is of high level at any given time, this pair having been selected by matrix 117. The outputs of the OR circuits on lines 124, 125 are amplified, inverted and clipped to give waveforms 157, 158, Fig. 2. These waveforms are differentiated by the grid networks of the bi-stable stage 154, as shown at 159, 160, Fig. 2, and the resulting pulses trigger the bi-stable circuit so that output pulses 161, 162, Fig. 2, are produced and may be fed to further stages of the apparatus.

Title: Improvements relating to detector arrangements for velocity modulation electronic tube structures
IPC: H03D1/26
Filed: 1942-05-13
Abstract: 639,982. Velocity - modulated tubes. STEVENS, A. H. (Leland Stanford Junior University, Board of Trustees of). May 13, 1942, No. 4043/44. Divided out of 639,981. [A Specification was laid open to inspection under Sect. 91 of the Acts, Aug. 14, 1946.] [Class 39 (i)] [Also in Group XL (c)] A velocity-modulation tube has a detector arrangement which separates and separately collects the fast and the slow electrons, the separate collecting means being connected to a push-pull output circuit. The beam from cathode 5, after passing through buncher resonator 1 and catcher 2, arrives at grids 21, 22, grid 21 being at anode potential and grid' 22 around cathode potential. The system acts as a mirror for slow electrons and deflects them sideways to collector 24, while the fast electrons pass through to collector 23. The potential of grid 22 is adjusted for maximum rectification at the top or bottom bend of the collector characteristic. Collectors 23, 24 are connected in push-pull, as by transformer 26, to a receiver 27. The arrangement shown is adapted to act as a regenerative oscillator-detector for detecting distant objects as in Specification 639,981, and includes a non-linear feed-back path comprising auxiliary buncher resonator 3 and catcher 4 for preserving constant mutual conductance, as in Specification 639,983. Specifications 523,712, 529,771 and 531,251 also are referred to.

Title: Improvements in and relating to train control systems
IPC: B61L3/12
Filed: 1928-02-09
Abstract: 311,309. Associated Telephone & Telegraph Co., and Hudd, A E. Feb. 9, 1928 Track apparatus for stopping trains.- The operation of the brakes of a train is initiated by the action of magnets on the track on an armature which strikes and actuates mechanically a valve which may be reset either by the armature or by pneumatic handcontrolled means. The locomotive carries two releasing valves which co-act with track magnets on opposite sides of the track and are connected by reversing valves so that one serves to cause a partial brake application at a caution signal unless manually controlled within a predetermined time while the other causes a full brake application as soon as it is operated, and can only be reset after a time interval has elapsed. The track magnets at a distant signal consist of a number of permanent magnets A1 and a number of electromagnets of reversed polarity 131 which are placed a short distance ahead of the permanent magnets and are energized only when a train is over rail 49 and the signal is at danger to close a switch in the circuit. The train carries two receivers, one of which is shown in Fig. 3, which are connected alternatively by the reversing valve RV<a> to the caution brake application valve 18 and whistle 13 or to the full brake application valve 23. On passing a track permanent magnet A1 at a distant signal the polarized armature 2a is reversed and opens the valve 3<a> controlling the diaphragm valve 7a. At a distant signal the pipes 9 is put to atmosphere and the whistle valve 12 is opened to sound the whistle 13. At the co-operating electromagnet B1, if the distant signal is at clear, the armature 2a is reset and the valves are restored. If the signal is at danger, the valves remain open and the chamber 15 is charged after a given time to the pressure required to open the brake valve 18. The driver can reset the armature 2a by use of the acknowledging lever AL which, though the valve RVb causes air to enter the pipe 21, Fig. 5, corresponding to pipe 27, Fig. 3, and to draw the armature to its normal position. At a home signal the electromagnets EC are superposed in pairs on the pairs of permanent magnets PM so that when energized there is no effect on the receiver BR. At a danger home signal, the permanent magnets reverse the armature 2a and through the pipe 9a open the full-brake application valve 23. The armature 2a can be reset by the driver actuating the releasing lever RL, only after sufficient time has elapsed for reduction of pressure in the chamber RA.

A half bearing shell 7 with an inner antifriction lining is formed from a blank 1 by a process of bending and rolling between rolls 3 and 4. The strip is fed at an angle α to the plane 6 of the rolls by a guide 2, is curved at A, and reduced slightly in thickness at B. The reduction is 0À5-1%, and the angle α between 10‹ and 30‹. The strip 1 can be gripped at its leading end by a radially retractable claw 8, Fig. 2, a corresponding recess 9 being provided in the roll 4, or by a pair of adjustable lateral claws which grip each edge of the strip and are able to pass through the roll gap. The bearing can be formed with a lug at its trailing end for locating the bearing in a recess in its housing, the lug being formed by a knife on roll 3 which displaces part of the bearing into a corresponding recess in the roll 4. The slightly higher specific loading of the rolls on the leading and trailing ends of the bearing, owing to the smaller volume of the material within the pass, creates a marginally greater reduction at the ends leading to a desirable oval bore. A slight amount of machining on the ends of the bearing is normally all that is required to finish the bearing.
