Patent GB-588790-A (GB)
Title: Improvements in or relating to automatic switches for use in telephone or like systems
IPC: H04Q3/00
Filed: 1945-03-07
Abstract: 588,790. Automatic exchange systems. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd., TAYLOR, R., and BAKER, G. T. March 7, 1945, No. 5659. [Class 40 (iv)] In a two-motion group selector, hunting is initiated by the release of a. relay during the pause at the end of the impulse train and a pre-operated test relay is held over the test terminals as long as busy lines are encountered. The invention relates to the type of switch described in Specification 447,767. When the switch is seized, relays A, Band C operate in turn, the vertical magnet VM and rotary magnet RM being in series with B and C respectively. During impulses A responds and steps VM by intermittently short-circuiting B. Vertical off-normal contacts N2 operate test relays HA, HB over their high-resistance windings and C is then short-circuited at each reoperation of A so that it falls back at the end of the train and completes the circuit for rotary magnet RM over drive springs RMC and lowresistance windings of HA. HB. Hunting now commences and, at each step, drive springs RMC open the circuit over the low resistance windings of HA, HB, leaving these relays dependent on earth applied over the test wipers P1, P2, contacts NR4, NR5 now being open. An idle line is characterised by absence of earth and if this is ecnountered over PI, test relay HB releases, thereby releasing HA and breaking the drive circuit. Shunts provided by YE, YF give slow enough release time to cover momentary breaking of the circuits if the wipers overshoot the correct contact. The short-circuit is removed from C, which reoperates HA over c5, to switch the speech wires through. If the idle line is found over P2, HA releases but HB remains held over b4. Other operations are, however, similar and the speech wires are switched through over the +2, - 2 wipers. If both test wipers encounter free lines simultaneously, both test relays release and the reoperation of C followed by HA gives preference to the +1, - 1 wipers. In the case of no free outlet being found, cam springs S2 operate on the eleventh step, operate an overflow meter on lead 16 and release HA, HB. This again reoperates C and HA, so connecting back the incoming speech wires to the outer windings of relay A, in which busy tone is induced from leads 11 and 12. If the switch is a first selector, terminals 14, 15 may be strapped so that it is guarded immediately upon seizure by the operation of A, as described in Specification 574,312.

Filed: 1938-02-23
Abstract: 501,992. Sewing-machines; creasing trousers &c. SEGELIN, D., and SEGELIN, S. Feb. 23, 1938, No. 5697. [Classes 112 and 141] A permanent crease in garment fabrics is produced by holding the creased fabric with the crease standing up at rightangles to the plane of the fabric and the inner surfaces of the crease in contact and stitching a tape to the fabric at the lines of bending of the fabric at the sides of the crease. The operation may be performed in a sewing-machine having two needles 9, which may be staggered, and a presser-foot 1 formed with a groove on its underside to receive and guide the crease 3 in the fabric 13, the tape 10 being fed in under the fabric to be stitched to the fabric close to the sides of the crease. The fabric 13 is guided into the groove of the presser-foot 1 by an adjustable thin guide finger 5, and the tape 10 is supported during stitching by a tongue 12. The depth of the finished crease may be varied by moving the finger 5 towards or away from the presser-foot so that the edge of the crease is higher or lower in the groove of the presser-foot, or by tensioning the material from both sides of the presser-foot to draw the crease to the required height.

Abstract: 194,299. Schieferstein, H. March 1, 1922, [Convention date]. Addition to 188,633. Machinery, utilizing inertia to obtain movements in.-The method of and means for transmitting energy through mechanically oscillating members described in the parent Specification, is utilized instead of the usual escapement mechanism for maintaining oscillations of pendulums and balance wheels in mechanisms for the determination of time, the oscillating member being thus energized in a substantially continuous manner and the controlling or impeding action of such member upon the driving system being likewise substantially continuous. The pendulum, balance wheel or the like is coupled through a spring of suitable elasticity to a crank rotating at a rate approximately corresponding to the natural period of oscillation. In the form shown in Fig. 1, the crank c operates the pendulum a through a con. necting, spring k, the length of the spring differing from that of the crank arm. In a modification, the crank c oscillates an intermediate suspended member connected to the pendulum by tension or compression springs. As shown in Fig. 3, a flat spring k carried by the pendulum a, is connected, to a crank c which is driven through reduction gearing from a weak electric motor connected to a lighting circuit, or from spring or weighted actuated driving mechanism. A spring e may be inserted between the crank shaft c and the driving gear r<1>, or an elastic cord drive may be employed, to equalize the working of the mechanism. In the arrangement. shown in Fig. 4. a balance wheel a. elastically constrained by a spring f is oscilnated by the crank c acting through a link b, swinging arm d, and a coupling spring k.. The Specification as open to inspection under Sect. 91 (3) (a) comprises also an arrangement of clock mechanism, Fig. 6 (Cancelled), in which a bucket wheel i, driven by liquid or gaseous impulses from a nozzle h, drives, through a spring w, the crank wheel c, which is connected in the manner described above to a pendulum and which also actuates time-indicating mechanism through gearing as shown, the combined spur and crown wheel l actuating planet wheels m m<1> engaging a crown wheel n carrying the minute band t, the hour hand being driven through gears o, p, q, r. This subject-matter does not appear in the Speci. fication as accepted. Reference has been directed by the Comptroller to Specification 2857/02, [Class 139, Watches &c.].
