Title: Magnetic telegraph recorder and transmitter
IPC: H04L13/08
Filed: 1967-03-03
Abstract: 1,145,192. Magnetic drum stores. INTERNATIONAL STANDARD ELECTRIC CORP. 3 March, 1967 [4 March, 1966], No. 10177/67. Heading G4C. [Also in Division H4] Serial data from a teleprinter is recorded on a drum store in parallel form, the position at which the parallel data is stored being determined by a counter-comparator arrangement. The serial data is converted to parallel and stored on bi-stable units. The start bit of each character data group causes a write counter to advance one step, e.g. to count n. The drum store comprises a clock track which gives a pulse for each character position. These clock pulses step a counter, reset at each revolution, and when the count reaches n a comparator opens gates to pass (in parallel bit form) the character stored on the bi-stable units to the write head; phase modulated coding may be used. The next character from the teleprinter will similarly be written in to position n + 1 on the drum. When a character is to be read from the drum a read counter is stepped, so indicating the position of the required character. When the clock counter shows the same count as the read counter the parallel data is read out from that position on the drum. The next character is read from the adjacent position. The read-out and write-in rates may differ.

Abstract: 825,484. Sliver-winding apparatus. PRINCE-SMITH & STELLS Ltd. Feb. 18, 1958 [March 29, 1957], No. 10342/57. Classes 120(1), 120(2) and 120(3)  In apparatus for forming cross-wound sliver packages C on a freely rotatable spindle 16 held against a driving roller 17, when a predetermined measured length of sliver has been wound a doffing mechanism operates whereby (a) feed of sliver to the winding point is interrupted and the package and spindle are moved to a doffing position, (b) a doffing member 38 moves to doff the package, (c) spindle 16 and member 38 are returned to their initial positions and (d) feed of sliver to spindle 16 is restored. Loading mechanism. Spindle 16 is carried on a pivoted arm 20 which, during winding, is pressed towards roller 17 by an hydraulic jack 18 supplied with pressure fluid by a pump 22 via a valve 24. Measuring. When a counter 30 associated with roll 17 indicates a predetermined length of sliver, it operates switches to stop delivery of material from a gill box and also energizes a solenoid 27 controlling valve 24. Doffing. Movement of valve 24 by solenoid 27 applies hydraulic pressure to the other end of jack 18. Arm 20 is thereby rocked to lower the wound package C to a doffing position, Fig. 6, opposite a tray 31. As the jack ram 181 passes a post 32, Fig, 1, pressure fluid is admitted to a second jack 34 to cause its cylinder 341 to move to the right. Cylinder 341 is connected by a pivoted lever 35 to a slidable doffing plate 38 which is thereby also moved to the right, Fig 1, to push package C off the spindle on to tray 31. As the package leaves the spindle the sliver extending from the traverse guide 15 is engaged by a spiked wheel 39 and a spiked bar 40. At the end of its stroke, plate 38 trips a switch N to re-set counter 30 and de-energize solenoid 27 so that jack 18 is again reversed, whereby spindle 16 is pressed into contact with roller 17 and a switch R in the feed motor circuit is closed; at the same time, jack 34 is reversed so that plate 38 is returned to its initial position, closing a second switch P in the feed motor circuit whereby delivery of sliver is resumed. Simultaneously spiked wheel 39 rotates to break the sliver from the tail end BT held by bar 40, and to wrap the new end around the empty spindle.

Title: Improvements in or relating to cylindrical anisotropic permanent magnets
IPC: C04B35/26
Filed: 1954-04-08
Abstract: 758,962. Magnetic structures; permanent magnet machines. PHILIPS ELECTRICAL INDUSTRIES, Ltd. April 8, 1954 [April 11, 1953], No. 10368/54. Classes 35 and 38 (2). [Also in Group V] A cylindrical anisotropic permanent magnet with poles distributed around its periphery, suitable for use in synchronous motors and bicycle dynamos, is made from a material consisting of non-cubic crystals of mixed oxides of iron and at least one of the metals Ba, Sr, and Pb, and if desired Ca, such as forms the subject of Specification 708,127, by a moulding process during which favourable directions for magnetization are produced, the body being subsequently sintered. Powdered material for forming a six-pole magnet is introduced with a liquid into space 12, in a mould and compressed by a ram 10, the liquid being expelled through holes 8 in the base 7 of the mould, which holes may be covered with filter paper. The mould comprises an outer casing 6 in which are fitted permanent magnets 1, 2, 3 separated by non- magnetic parts 5, and having non-magnetic inserts 4 to form the poles. The magnets may be formed of material similar to that used to make the cylindrical magnet, or of a Mn-Bi alloy. The magnetic flux produced by the permanent magnets 1, 2, 3 creates favourable directions for magnetism in the moulded magnet. The magnets 1, 2, 3 may be formed together in one piece, Fig. 3 (not shown), or each magnet may be in two pairs, separated if necessary by non-magnetic material, Fig. 4 (not shown). A projection 11 on the ram may pro. vide a spindle hole in the cylindrical magnet, and projections on the mould may mark the pole places. The grinding needed to the magnet owing to unequal shrinkage may be reduced by using a non-circular mould. Specification 747,724 also is referred to.

Title: Method and apparatus for lubricating bowden cables
IPC: F16C1/24
Filed: 1928-04-10
Abstract: 291,432. Kramer, R. June 2, 1927, [Convention date]. Pliers.-Bowden cables are lubricated by bending the cable within the elastic limit so as to produce spaces between the coils of the casing, through which spaces lubricant is then injected. In the appliance shown, a curved jaw b is secured to a member a and a similarly curved jaw c is mounted at the end of a cylinder i which is slidable in apertured lugs h on the member a. The arm q of a lever p pivoted to the member a passes through a slot o in the cylinder i and engages a recess n in a spring-pressed piston m mounted in the cylinder. A lubricant container alpha containing a spring-pressed plunger and mounted on the member alpha is adapted to communicate with the interior of the cylinder through a port k therein. In operation, the cable d being arranged between the jaws b, c, the lever p is moved towards the member a so as to move the cylinder assembly towards the jaw b, whereby the cable is gripped between the jaws and bent into arcuate form. Continued movement of the lever causes the piston m to move forward in the cylinder, ejecting lubricant past a non-return valve v through the jaw c into the cable. As the parts are returned to normal position, a fresh charge of lubricant is drawn into the cylinder from the container e. The jaws are formed so as to prevent leakage. According to the Specification as open to inspection under Sect. 91 (3) (a) the appliance may be arranged to stretch the cable instead of bending it. This subject-matter does not appear in the Specification as accepted.

Title: Improvement in non-return valves
IPC: F16K15/06
Filed: 1933-04-08
Abstract: 402,320. Non-return valves. MARTIN, 0., Bekkelagah÷gda, near Oslo, Norway. April 8, 1933, No. 10547. Convention date, Oct. 25, 1932. [Class 135.] A non-return valve is maintained in closed position under the action of a plurality of pivoted sliding arms, which are spring-pressed against the generally conical surface of a head attached to the valve, the closing force being reduced as the valve opens by a decrease in the angle of the conical surface of the head in relation to the direction of opening movement. In the form shown, the valve 3, which is adapted to open into the vacuum-tube 1, is restrained by springs 9 acting on levers 7 having rollers 6 bearing against the curved surface 10 of the valve-stem. A considerable vacuum is necessary to move the rollers past the shoulder 12 after which they move more easily on the slightly-sloping portion 11 and the valve is easily maintained open until the vacuum in the pipe has greatly diminished. The initial closing is assisted by the spring 13.
