Filed: 1939-02-08
Abstract: 524,829. Electric signalling systems. BRITISH WESTERN UNION, Ltd. Feb. 8, 1939, No. 4153. Convention date, Feb. 19, 1938. [Class 40 (i)] [Also in Groups XXXVI and XXXVII] A submarine cable-laying device of the kind described in Specifications 452,141 and 503,326, [both in Group XXXVI], is provided with means for transmitting to the cable-laying ship towing the device or other remote point indications of the tension in the cable as it passes through the device and also, preferably, indications of the angle at which the cable enters the device. The transmitting devices may comprise rheostats 35, 50, Fig. 2, mounted on the cable-laying device and actuated respectively by the lead of the cable as it enters the device and the pressure of the cable upon a pivoted guide roller as it passes through the device. The rheostats are connected by the conductors 90, 91 of a pilot cable, which connects the ship and the cable-laying device, to indicating instruments 95, 96 on board the ship, the instruments being connected in circuit with a battery 92 and ballast resistances 94. The circuits from the battery to the rheostats are completed through the water in which the cable is being laid. The rheostats may be of the construction described in Specification 524,828, [Group XXXVI]. The rheostat 35, Figs. 3 and 4, is operated by links 37, 38 which are controlled by a feeler 40 engaging the cable C as it enters the bell-mouth 24 of the device, the feeler pivoting about an axis 43 as the inclination of the cable varies. The rheostat 50, Figs. 3 and 8, is controlled by the pressure exerted by the cable on a guide pulley 27, the pulley rotating on axle 68 which is pivoted about an eccentric axis 68a. A spring 71, Fig. 4, urges the axle 68 about the axis 68a in one direction, whilst the pressure of the cable on the pulley 27 urges the axle in the opposite direction, so that the angular position of the axle relatively to the axis varies with the tension on the cable. A linkwork 52, 53, 55 transmits the relative movement to the spindle 51 of the rheostat 50.

Abstract: 650,713. Magnetic induction accelerators. AKT.-GES. BROWN, BOVERI, & CIE. Feb. 18, 1947, No. 4736. Convention date, Sept. 3, 1943. Drawings to Specification. [Class 39 (i)] In a magnetic induction accelerator both the induction and guiding fields are excited by means of two windings through which in-phase or approximately in-phase voltages are passed, one winding embracing both magnetic fields, while the other embraces only the induction flux. The magnetic reluctance to the induction flux is substantially smaller than to the guiding flux, and the number of turns of the two windings is so chosen that the field strength of the guiding field is half the mean field strength of the induction field when the two windings are connected to the same exciting voltage. A small air gap may be provided for the induction flux, but is preferably omitted. By adjusting the ratio of the number of turns of the two windings, the electron path radius may be adjusted. The magnetic induction accelerator may have a D.C. biassing field applied to the guiding field. The Specification as open to inspection under Sect. 91 comprises also the connecting of the two windings to different in-phase voltages, whose ratio may also be adjusted to vary the electron path radius. This subject-matter does not appear in the Specification as accepted.

Abstract: 453,196. CrÛpe - twisting artificial filaments. BRITISH CELANESE, Ltd., and DREYFUS, H., 22, Hanover Square, London. March 8, 1935, Nos. 5033/36, (divided out of 438,589), and 10411/36. [Class 120 (iii)] Threads of filaments of cellulose esters or ethers which have been stretched are subjected to crepe-twisting and at least the last part of the crÛpe-twisting is inserted while the filament is under the influence of steam. Preferably steaming takes place under such conditions that moisture is present. The amount of twist given to the threads is less than that required to secure a similar crÛping power in a thread of the same final denier without a preliminary stretching operation, e.g. the twist is less than a maximum of 70 turns per inch for a thread of 160 denier, and 85 turns per inch for a thread of 115 denier. As examples of suitable stretched filaments there are mentioned those prepared according to th e processes described in Specifications 277,089, 323,790, [both in Class 120 (iii)], 370,430, 371,461 ; and 438,584, 438,585, 438,586, 438,587, 443,707, and 443,773, [all in Group IV]. The threads may consist of continuous filaments or spun discontinuous filaments, and may contain delustring, loading, or other water-insoluble compounds. The stretched threads may be prepared, twisted, and steamed in the manner described in Specifications 437,019 and 438,590. Suitable steaming apparatus is described in Specification 440,653. Specifications 304,806, [Class 120 (ii)], 348,589, 424,683, 424,752, 424,830,424,879, and 441,573, also are referred to.

Abstract: 783,401. Snap-action switches; momentarycontact switches. LAURE, M. H. H. Feb. 20, 1956 [Feb. 28, 1955], No. 5240/56. Class 38 (5). A switch comprises a dead-centre spring which gives a contact lever a stable position on each side of the dead centre, a reciprocable actuator and an intermediate member so arranged that during a first part of the travel of the actuator the member acts on one end of the contact lever to move it in one direction across dead-centre, and during the second part of the travel the member acts on the other end of the contact lever to pivot it in the other direction across dead-centre, the spring when released causing the actuator and the intermediate member to return to their initial positions whilst leaving the contact lever in the position reached at the end of its second movement. In one form (Figs. 1, 4 and 5), the contact lever 19 is pivoted at 20 and is pivotally connected at 22 to the intermediate member 23 which is acted upon by the dead-centre tension spring 25 having a fixed point n. The member 23 has a shaped end 33 co-operating with a recess 30 in a push-button 24, depression of which to the Fig. 4 position causes counter clockwise movement of lever 19 to engage contacts 21 with fixed contacts 10 with a snapaction. Further movement of the button 24 to the Fig. 5 position causes the lever 19 and member 23 to tilt clockwise to re-open the contacts with a snap-action, the spring 25 restoring the button 24 and member 23 when the button is released. The partsi, j of the button 24 may be differently-coloured so as to serve as indicators. In another form (Figs. 6, 7), the contact lever 36 is connected at 39 to a member 38 which has a slideway formed by parts 40, 41 and engaging a collar 42 on the button 43, and the member 38 is acted upon by a torsion spring 47. The actuator may comprise a pivotable member, e.g. a cam, acting on a push-button, and the spring may be a compression spring.

Abstract: 879,530. Percussive tools. WARSOP POWER TOOLS Ltd. Feb. 17, 1958 [Feb. 15, 1957], No. 5279/57. Class 124. A rock drill comprises a tool holder, a hammer having a stem cooperating by splines with a sleeve formed with a ratchet wheel and with the tool holder, one spline being axial and the other helical, a first member movable between a position permitting a pawl to engage the ratchet wheel and a position preventing such engagement, and a second member movable between a position preventing rotation of the tool holder and a position permitting the tool holder to rotate. As shown, a ratchet 5 formed on a sleeve 4 co-operating with helical splines on the stem of a hammer may be engaged by two pawls 28 and 30 when a half-ring 32 of wire having its ends turned axially, is in the position shown. On moving a finger-grip 38, attached to a loop 34 on the wire, to the right in Fig. 2, the ends of the wire engage the pawls and prevent them from making contact with the ratchet. In order to prevent rotation of the tool holder, a pin 48 having a head 50 is rotatably and longitudinally movable in a bore just intersecting the tool holder. A cut out portion 58 in the pin, Fig. 5, allows the tool holder to rotate, but on turning the pin through 180 degrees and moving it to the right a taper portion 56 wedges the tool holder and prevents its rotation. The head 50 may cooperate with the outer surface 60 of the housing to set the pin in the position in which the cut away portion allows rotation of the tool holder.
