Patent GB-555982-A (GB)
Title: Improvements in yarn twisting and winding devices
IPC: D01H13/18
Filed: 1942-03-09
Abstract: 555,982. Winding and twisting yarns. BRITISH CELANESE, Ltd. March 9, 1942, No. 3046. Convention date, March 8, 1941. [Class 120 (ii)] In a yarn winding or winding and twisting device the yarn is severed on its way to the nip or feed rollers between a platen and a member having a cutting edge when breakage occurs beyond the rollers, the yarn being guided across the platen by a means which permits it to follow a path that is deflected laterally beyond the end of the cutting edge whereby immediately prior to the operation of the device the yarn may follow such deflected path and be held therein by the end of the member having the cutting edge ; upon operation of the device the yam assumes its running position, straight across the face of the platen and just out of contact therewith. As shown a collar 19, fixed to a shaft 18 by flanges 20, 21, has the flange 21 extended to form the cutting edge 22 which cooperates with the platen 29a extending from a base 15 in which the shaft 18 is journaled and which is fixed by a yoke 11 to a cross-bar 10 disposed adjacent the nip rollers 13, 14. A yarn guide 26 is formed at the end of a wire 25 fixed to the shaft and at the side of the shaft remote from the guide the wire carries an adjustable conterweight 27 ; normally the yarn holds the guide down against the action of the counterweight but if the yam should break the counterweight turns the shaft and brings the cutting edge against the yarn and platen and severs the former which is thus prevented from forming a lap about either of the rollers 13, 14. A lip 23 at one end of the cutter co-operates with a hole 34 in the platen to deflect the yarn 35 in its path across the platen from the supply to a guide 36 and the rollers, the yarn passing over a wire guide comprising a pair of rods 31, 32 fixed to the platen ; rotation of the arm 25 upon operation of the twisting device causes withdrawal of the lip 23 from the hole 34, the yarn then running straight across the platen from the rod 31 to the rod 32. The free end of the platen is curved to guard the cutting edge and the rotation of the shaft is limitedly by an adjustable stop on the shaft cooperating with the yoke 11. In modifications, the yarn is held in the deflected path by the unsharpened edge at the end of the member having the cutting edge and the wire guide and platen are differently arranged.

Title: Improvements in or relating to electric switches
IPC: H01H71/10
Filed: 1924-02-06
Abstract: 233,411. Cox, F. B. Feb. 6, 1924. Automatic circuit-breakers have a pivoted contact arm held by a detent in the closed position, a pivoted striker-bar being provided which is controlled by the no-volt or overload device and is adapted when released to strike the switch-retaining detent, the striker-bar being returned to its operative position by the joint action of the angularly-moving switch part and flexible means between this part and the striker-bar. As shown in Fig. 1, the pivoted contact blade A is provided with a retractive spring C and is connected by a spring e<2> to a coaxially pivoted striker-bar E controlled by the novolt electromagnet N. When the switch is closed (Fig. 3.) a pin d' on the switch blade A is engaged by a spring-controlled hooked catch D. During the closing operation the line of action of the spring e<2> is brought across the pivot e<1> but the bar D is held up by the electromagnet N, the circuit of which is completed before the deadcentre position is reached. On failure of voltage the bar E is released and moved downward bv the spring e<2> to strike the tail d' of the detent D and so release the switch arm A, which is moved to the off position by the spring C. During this opening movement the spring e<2> is again brought across the line of centres (Fig. 5) so that the striker-bar is automatically returned to the position shown in Fig. 1 in which it is controllable by the electromagnet N. A modification of this arrangement for overload release is shown in Figs. 6 and 7, in which the spring e<2> is not brought across the dead-centre position during the closing of the switch but is moved ,across by the plunger o<1> of the overload coil O. In further modifications also described, the striker-bar may be pivoted to an arm extending from the pivoted switch member, a spring connecting a point on the striker-bar with the pivot of the contact arm or an arm on the contact member may engage a yielding member such as a plate spring connected to the striker-bar which is pivoted on an axis removed from that of the contact arm. Specification 208,731 is referred to.

Title: Improvements in and relating to lever linkwork apparatus
IPC: E04F10/10
Filed: 1926-02-03
Abstract: 270,784. Murdoch, A. G. Feb. 3, 1926. Window blinds.-Relates to lever linkwork apparatus for supporting and moving into and out of operative positions shop blinds, &c. of the type in which a primary arm pivoted about a fixed axis is connected at its free end to one of a pair of toggle links the other of which is pivoted about a fixed axis, with means for operating the arm by opening and closing the toggle, and comprises the provision of a secondary arm carried by the primary arm on the same pivot as the toggle connection, with means for moving the secondary arm about the common pivot synchronously with the movement of the primary and toggle arms. An arrangement for supporting spring-roller shop blinds or awnings, shown in Figs. 1 and 2, comprises, at each end of the awning, a primary arm 39, a toggle pair 27,. 33 and a secondary arm 48. The lower toggle link 27 is mounted on a fixed pivot 28 whilst the primary arm 39 is swung upon a shaft 38 adapted to be rotated by hand or motor to close or open out tha linkage by driving through pinions 40, and bevel gears 43, 44, a shaft 45 mounted on the arm 39 and carrying or, through bevel gears, operating at its outex end a worm 46 meshing with a worm wheel 47 secured to the secondary arm 48 concentrically with the pivotal connection 34 of the arms. Also secured to the worm wheel 47 on the joint pin 34 is a sprocket wheel 35 connected by a chain 36 to a sprocket wheel 32 rigidly secured to the toggle link 27, so that the toggle is opened out from the position shown in Fig. 2 to that in Fig. 1 by the action of the chain gearing driven by the shaft 45 whilst the secondary arm 48 is unfolded. The blind or awning lath or support is carried by the outer ends of the arms 48 and the opening out movement may be limited by abutment lugs on the primary and secondary arms. The arms and links may comprise flat strips spaced by collars and secured on each side of the respective gear elements or they may be of channel, box or cylindrical form. The secondary arms may carry further arms opeated by an extension of the gearing. The gears &c. may be encased. The worm wheel 47 may be an annular segment co-planar with the sprocket wheel 35. In a modification the shaft 45 is mounted on the secondary arm 48 and is driven by a motor carried on the movable framework, the worm-wheel in this case being secured to the primary arm whilst the sprocket wheel is secured through its support to the secondary arm. The linkwork at each end of the blind may be operated by a single motor or by a pair of motors running in synchronism. The motors may be controlled by automatic switches actuated. by clockwork or by variations in the intensity of light, and may be automatically stopped and reversed at the end of the movement. Instead of being driven by the shaft 38, the movement of the primary arm about its pivot may be utilized to operate the gearing between the primary and secondary arms, the gearing carried by the primary arm co-operating, in this case, with a fixed segmental toothed rack.

Title: Improvements in or relating to the construction and manufacture of electric condensers and transducers
IPC: H02N2/18
Filed: 1948-02-04
Abstract: 664,493. Electric condensers. SONOTONE CORPORATION. Feb. 4, 1948 [Feb. 7, 1947], No. 3269/48. Class 37. [Also in Group XL (b)] A condenser comprises a thin layer of solid refracting dielectric 21, Fig. 3, opposite faces being coated with conductive electrode layers 22. A sheet of ductile metal 24 is mechanically and electrically united to at least one of the two electrode coatings as by soldering to provide a rigid support and to distribute mechanical strain to avoid fracture of the thin ceramic dielectric. The condenser may be employed as a signal transducer for converting mechanical signals into electrical signals and vice versa. The refractory dielectric material is composed essentially of random oriented titanate particles in the construction of a condenser, and when electrically permanently polarized in a predetermined direction relative to the electrode surfaces the dielectric material operates as a piezo-electric body. The purpose of the condenser construction is to enable extremely thin layers of solid dielectric material to be used for maximum capacity with adequate mechanical strength. A piezo-electric function for use in gramophone pick-ups, microphones, pressure-indicating devices, and the like, is obtained by means of a condenser arrangement shown in Fig. 5, 5A, which may be regarded as two condensers connected in series and placed in a circuit shown in Fig. 6. Alternatively a single battery 2-34 may be utilized, as shown in Fig. 6A, for charging the two condenser elements 2-25, 2-26. Permanent polarization or dielectrostrictive characteristics may be imparted to the dielectric titanate structure by connecting it to a source of D.C. so that a voltage gradient of about 60 volts per thousandth of an inch thickness is applied for a period of 5 minutes up to a day or more according to the characteristics of the titanate dielectric.

Title: Improvements in or relating to direction finding aerial systems
IPC: H01Q7/02
Filed: 1939-02-02
Abstract: 524,652. Aerials. TELEFUNKEN GES. FUR DRAHTLOSE TELEGRAPHIE. Feb. 2, 1939, No. 3566. Convention date, Feb. 2, 1938. [Class 40 (v)] In a retractable aerial system for use on a submarine with a radio-goniometer and comprising a plurality of aerials which are differently orientated in the extended position, means are provided for rotating the aerials into the same or parallel planes when retracted in order to reduce frictional drag. In Fig. 2, two frame aerials 4, 5 are symmetrically mounted about the fore-and-aft line of the submarine and are mutually perpendicular when in the extended position as shown. On retracting the aerials by means of the pressure cylinders 8, aerial 4 is rotated through 90 degrees so that both aerials lie.in the fore-and-aft direction and can fit into the spaces between the bulwarks and the casing. Alternatively, the two frames may be mounted concentrically, Fig. 5, in which case the larger frame is rotated athwartship since a transverse frame is less efficient than a longitudinal one owing to the shape of the submarine. The open-aerial component for " sense " determination may be obtained by earthing the electrical centre of the radio-goniometer fieldcoils through a coil which is coupled to the receiver input, the protecting tubes 11, 12 of the frame windings being insulated from the frame shaft 17 by the intermediate piece 18. When taking bearings under water, short-circuiting between the frame protecting tubes and frame shaft is prevented by covering them with an insulating coating. The crossed frames may be replaced by Adcock aerials.
