Patent GB-102726-A (GB)
Title: Improvements in the Manufacture of Styluses for Sound Reproducing Machines.
Inventor: MOYER WILLIAM WALTON
IPC: G11B3/46
Filed: 1916-12-08
Abstract: 102,726. Moyer, W. W. Dec. 11, 1915, [Convention date]. Needles for sound-reproducing machines are formed by closing the slotted end of the needle shank, which is of malleable metal, over a piece of fine tungsten or like metal wire forming the point. As shown in Fig 7, the mild-steel shank 1 has a conical rounded end 2 with a diametral slot 3, and is held in a slide 5 by straps 7. The slide 5 is advanced to bring the end 2 into a conically-recessed die 11 having its sides inclined at a greater angle than the end 2. The tungsten wire 18 is then inserted into the slot 3 through alined holes in a fixed block 17, a cutting-blade 14, and the die 11. Pressure applied by a hammer or otherwise to the back 8 of the shank causes the slot 3 to close over and to grip the tungsten wire 18, which is cut off by sliding the knife 14. Recesses 15, 16 allow the wire to bend during the cutting stroke of the knife. The shank 1 and its attached tip 21 are then removed from the die 11 and placed in a rotary holder 22, Fig. 12, and the tip is rounded off or bevelled by engaging an abrasive block or wheel 23. A groove 26 may be formed in the shank 1 by a suitable cutting- tool 27.

Abstract: 474,641. Door-latches. NETTLEFOLD & SONS, Ltd., and KETLEY, A. J. June 25, 1936, Nos. 17676 and 28375. [Class 44] A latch is operated from a plunger moving substantially parallel to the plane of the door by means located in a leg or stem on which the handle is mounted. A latch 9 is operated by a plunger 13 or 14 in handle 1 acting through a pin-and-slot connection 11, 12, which enables the reciprocating movement of the plunger to be converted into rotational movement of the follower. The shaft 5 connecting the follower to the pin- and-slot connection is located in the leg 2. Fig. 5 shows a pivoted lever 44 which is used to transmit the movement of the plunger 47 to the bell-crank 48 which withdraws the latch. A stop 49 is placed in the bottom end of grip bar 41 to preserve the symmetry of the latch and act as an abutment for spring 50 which tends to return the plunger 47 to its inoperative position. A modification in which a rack-andpinion connection between the plunger and latch is used is also described. The leg which is not carrying the latch operating mechanism may carry a key hole or barrel of a dead lock. The invention may also be applied to handles rigidly mounted on a single leg.

Void [Abridged as open to inspection under Sect. 91 of the Acts, Dec. 27, 1933]. [Class 40 (iii)] In a scanning device of the kind described in Specification 421,247, in which a revolving image is formed by means of a rotating internally reflecting prism, the image B, Fig. 1, rotates about its own centre O<1> and this revolves in an orbit about the centre O ; scanning is then effected by apertures 25<a> in a fixed disc 25, Fig. 2. The required rotation is produced by causing the beam B, Fig. 5, to enter the rotating prism or optomotor 22 at a point eccentric to the axis AA. It is preferably inclined to the axis AA of rotation, and strikes the first reflecting surface at a point B <1> on that axis. At the transmitter the light from the object 20, Fig. 3, is directed by lenses through the optomotor 22 and on to the fixed scanning-disc 25 and light-sensitive cell 28. Alternatively an image 28b of an arcuate filament 28a, Fig. 4, may be projected through an optomotor 22<a> on to the fixed scanning disc 25, and the pencil picked out by one of the apertures 25a is rotated by a second optomotor 22 so that it scans a picture 20, and light is reflected thence on to a light sensitive cell 20<a>. In a receiver, a modulated light-source is located at 28<a> and a viewing-screen at 20. The prism 22<a> may be replaced by the device shown in Fig. 9, or that shown in Fig. 12. The beam b, Fig. 9, is deflected by the prisms shown, one 36 of which can be adjusted by means of set-screws, so as to alter the position and inclination of the emergent beam, and the system is rotated about its axis through driving teeth 35. Alternatively, Fig. 12, a circular but eccentric part 47 of a lens may be used. A shutter may be provided so that some only of the apertures are exposed at each revolution.

Title: Improvements in or relating to the production of stocking tubes on double cylinder knitting machines
IPC: D04B9/46
Filed: 1964-04-29
Abstract: On completion of each stocking tube the loops on all of the needles of a superposed cylinder machine are cast off by causing all of the needles to be positioned in the bottom cylinder and lowered to a casting off position.  Thereafter for commencing a new tube the needles are raised and alternate ones transferred to the upper cylinder whereupon the needles in both beds are caused to take yarn. To ensure that the latches are open a pneumatic latch opener is provided which supplies a blast of air to blow the latches open.  The loose end of the yarn is trapped and severed close to the needles. The second course is knitted by the upper bed needles only and the third course by the lower bed needles only.  At this stage an elastic yarn may be introduced.  The fourth course is then knitted by the lower bed needles only and thereafter the needles of both beds take and knit the yarn.

Abstract: 681,550. Rope end attachments. N.F.B. DISPLACEMENT PUMP CO., Ltd. May 23, 1950 [July 6, 1949], No. 17888/49. Class 109 A ferrule permanently attached to a wire rope 8 comprises a tubular sleeve 1 the internal wall surface of which is formed with a number of axially spaced frusto-conical recesses 2 ... 6, the bases of which are all directed towards the outer end of the ferrule, the ferrule being secured to the rope by metal which bonds itself to the rope and extends into the recesses. The ferrule is slipped over the end of the rope to expose the end portion 9 which is then unlaid, the hemp core removed and the strands straightened to form a "brush". The ferrule is then moved over the "brush", inverted, and molten babbitting metal poured into the outer end 7 of the ferrule. The angle of slope of the recesses is preferably such that the metal extending into each recess carries an equal part of the total load applied to the rope relative to the ferrule. Thus the recess 2 is made with the greatest angle of slope and shortest axial length of any of the recesses, the remaining recesses having progressively smaller angles of slope and greater axial lengths, since the axial creep of the metal increases from the lowest to the highest recess. In the application shown, the ferrule has a rope socket comprising a split tubular member 10 fitted around it and supporting the head 11 of a tool &c. adapted to be lowered down oil well tubing. The member 10 is shouldered at 12 and 13 to engage over the end of the ferrule and under the head of the tool respectively. The socket may be detachably secured to the ferrule by clamping rings &c.

Title: Process and apparatus for correcting distortion produced in the transmission of telegraphic signals

Filed: 1946-06-14
Abstract: 654,352. Code telegraphy. BAYARD, H. M., and ROQUET, R. J. C. June 14, 1946, No. 17948. Convention date, June 1, 1945. Drawings to Specification. [Class 40 (iii)] A telegraphic transmission system for compensating the characteristic distortion of a telegraph line comprises a compensating network connected in cascade with the telegraph transmission line, and a telegraphic relay is interposed between the transmission line and the network at each junction between the network and the transmission line, the arrangement being such that the differences in the delay of reproduction of the characteristic instants, i.e. changes of polarity of signal elements, of the signal modulation due to the transmission line are compensated by the corresponding differences of delay introduced by the compensating network. A " telegraph relay " is defined as a relay device designed to receive telegraphic signals and to retransmit them with reproduction of the specific characteristic instants of the original telegraphic signals with differences of delay depending on the telegraphic distortion of the line or network through which the signals have been transmitted. The network may be at the transmitting end of the line and disposed between a signal transmitter and the telegraphic relay applying the compensated signals to the transmission line. Alternatively, the input to the network comprises the telegraphic relay and the output directly controls a signal-receiving device. If the network is interposed between two parts of the transmission line, a telegraphic relay is included between the first part of the line and the input to the network, and a further telegraphic relay is disposed between the output end of the network and the second part of the line. The network is designed and determined in relation to a given transmission line to provide a distortion complementary to that provided by the line for predetermined sequences of signal elements. The Specification includes theoretical discussion on the variation of the delay distortion expected to arise as a result of any polarity change, i.e. characteristic instant, in relation to the nature of the individual signal elements of a sequence preceding the characteristic instant, and indicates how networks may be determined in order to provide appropriate compensating or complementary delays. Alternatively the form and components of the networks may be determined by the comparison of the characteristic distortions produced when signal elements preceded by predetermined groups of elements are transmitted over the line and through the network. The network is adjusted so that the delays imposed by the line and network are complementary or, in other words, the sum of the respective delays is approximately constant for each of the various groups of signal elements preceding the signal element being transmitted. Specification 652,601 is referred to.
