Title: Improvements in switching arrangements for automatic telephone systems
IPC: H04Q3/42
Filed: 1930-10-15
Abstract: 365,620. Automatic exchange systems. TELEFONAKTIEBOLAGET L. M. ERICSSON, 33, Kungsgatan, Stockholm. Oct. 15, 1930, No. 30874. Convention date, Nov. 6, 1929. [Class 40 (iv).] In a system in which talking connections are established over the line switches of the calling and called parties under control of a register marker, as described for example in Specification 311,709, [Class 40 (iv), Telephones &c.], the subscribers are arranged in two groups having different calling facilities, and the trunks accessible to the line switches have separate b wires corresponding to the groups and leading to corresponding impulse relays M1, M2 in the register marker. The completion of a call between subscribers in different groups therefore requires the operation of a switching relay SR to connect the b wires of the trunk. As shown, subscribers of the A group are debarred from calling the B group, whereas subscribers of the B group may call certain subscribers of the A group. This is effected by making the switching relays SR dependent on a relay R the circuit of which is completed over the banks of the number registers R1, R2, R3 and a front contact of the impulse relay M1 corresponding to the B group.

Title: Improvements in or relating to article-combining conveyor apparatus
IPC: B65G47/68
Filed: 1961-08-28
Abstract: 930,345. Endless conveyers. GEO. J. MEYER MANUFACTURING CO. Aug. 28, 1961 [July 6, 1961], No. 30917/61. Class 78 (1). Articles such as cans and bottles, which may not necessarily be of uniform sizes, are fed three abreast from a delivery belt E via belts D, C, and B to a belt A on which they are arranged in single file, there being means to avoid the clearance of jamming of the articles by manual means. If a jam occurs, a guide 23 is deflected to operate a switch LS2. This momentarily stops motor MM and CM which respectively drive belts D and C. If this clears the jam within one second, motor CM is immediately restarted, and motor MM is restarted after a further second. Otherwise after one second, motor OM is caused to run at half speed and after two seconds motor CM commences to run in reverse at half speed. At the same time, an air piston and cylinder 28, 29 are actuated so as to retract the trailing end of a guide rail 26. This relieves the jam and switch LS2 consequently re-closes. After two seconds from LS2 re-closing, motor CM stops and rail 26 is returned to normal position. After a further second, motor CM re-starts at normal forward speed and motor OM increases to full speed. Two seconds after the latter changes, conveyer D recommences and normal running conditions are thus restored. The necessary time delays are provided electrically and circuit diagrams are provided in the Specification (Figs. 5 to 8, not shown) but are not described.

Abstract: 713,741. Cemented pile fabric. SCHUELER, G. B. E. March 19, 1952 [Dec. 19, 1950], No. 30965/50. Classes 142(1) and 142(4) The ends of pile yarns are doubled over and the bends adhesively secured to a backing. The yarns a, arranged in parallel rows, may be drawn from beams, the yarns of each row being drawn from one beam; alternatively, each yarn may be drawn from a separate bobbin. A tension device, Fig. 4, comprises a grooved wheel 48 on each beam or bobbin spindle 42 braked by a cord 49 which may be nylon. One end of the cord is attached to a spring 50 and the other end to a member 53 connected by a link 54 to a solenoid 55. When the solenoid is energized, the member 53 moves towards the pulley 48, the cord slackens and yarn may be drawn off. The yarn beams, or bobbins, are mounted on a separate frame-work fitted with castors and latched to the fabric-making machinery. Yarn feeding mechanism comprises two sets of parallel bars 68, 68<SP>1</SP>, Fig. 13, each set mounted in a frame. The frames are moved towards each other to grip the yarns and both frames are then moved as a unit to feed the yarn forward. The frames are moved by cams operated by gearing from an electric motor. The yarns next pass to separating mechanism, Fig. 9, comprising separators 97 mounted in a frame 91, each separator having rows of pins 105-107 between two plates 99, 103. Locking bars 123, Figs. 9, 13, lie. beneath the separators 97 and are moved against the latter to grip the arms. Doubling mechanism for the yarn ends is positioned above the separators and comprises parallel bars 132 movable downwardly between the plates 98, 103 to fold the yarns over the tops of the. plates 98. The bars 132 are held in their raised position by latches 136. A slide 140, driven by a lead screw, moves past the bars 132 and carries a lever 137 and roller 138. A cam mechanism 139 depresses the members 137, 138 to successively release each latch 136 and depress each bar 132. The separators and locking bars, 123, are raised by cam mechanism 141. A cutter 143, carried by the slide 140, comprises a pair of reciprocating toothed plates. The drive may be to one plate by a crank mechanism. A deflector plate 146 on the cutter folds the yarn ends across the tops of the plates 98 prior to the downward movement of the bars 132. A heated hexagonal drum acts as a platen to secure the pile loops to a backing 148. The backing may be shrunk after pile attachment; the shrinking may be in one direction only. The backing may be corrugated, and may be of paper, cardboard, wood panels, asbestos, or felt, or when making imitation fur, may be leather or imitation leather. The yarns may be fed - upwards, as shown in Fig. 13, or may be led horizontally. Specification 692,422 is referred to.

Filed: 1928-10-26
Abstract: 312,888. Jones, L., and Pougher, J. H. T. Oct. 26, 1928. Toothed wheels; chaindriving.-In toothed gearing, the smaller wheel P has six teeth arranged staggered as shown and the larger wheel and has thirty six teeth similarly staggered. The addendum of the teeth of the wheel P are formed part circular and part involute and the dedendum circular. A length L<k> is made equal to three quarters of the chord of the circumferential pitch of the wheel G and is rotated about a point x on the pitch circle of the wheel P and finally wrapped upon the pitch circle so that outside the tangent at the point x the curve is circular and within that tangent it is involute with the pitch circle as its base circle. The radius of the dedendum curve is equal to one quarter of the said chord. In the wheel G, the radius of the addendum curve is equal to one quarter of the chord and that of the dedendum curve three quarters. The dedendum curves are each cut by a rotating tool, and the addendum curves of the wheel G by the same tool which cuts its dedenda, the wheel being rotated about the centre V of its addendum curve. The addendum of the wheel P is cut similarly, but translation motion is superposed when cutting the involute part of the tooth. In the modification shown in Fig. 4, the teeth of the wheel G are all brought into the same plane and the teeth of the whel P are restricted to those parts which overlap in Fig. 1. The teeth of the wheel G, Fig. 4, may be replaced by rollers of radius one quarter of the chord referred to and the wheel may be replaced by a chain carrying rollers of that size, the wheel P then serving as a chain-wheel.
