Title: Improvements in and relating to the magnetic purification of fluids
IPC: B01D35/06
Filed: 1941-05-13
Abstract: 549,391. Magnetic separators. MAGNETOS LUCIFER SOC. ANON. May 13, 1941, No. 6180. Convention date, Sept. 10, 1940. [Class 72] In the magnetic purification of fluids, the latter is caused to flow in the air gap of a magnet in a direction approximately normal to the lines of force of the magnetic field and the ferromagnetic particles in suspension in the fluid are attracted by attraction surfaces arranged approximately normal to the lines of the field and are subjected to the action of the fluid in movement, the extracted particles being accumulated magnetically and mechanically on surfaces defining accumulation spaces in which the intensity of the magnetic field is weak and which are located outside the stream of fluid. In one form of apparatus for carrying out the purification, elements 3, Fig. 1, of ferromagnetic material are placed between the soft steel poles 2 of a horse-shoe magnet 1 approximately normal to the lines of force of the magnetic field and the direction of the fluid indicated by B. The elements 3 are provided with accumulation faces which define free spaces formed by holes 6 adapted to receive and retain the particles extracted from the fluid. In another form, Fig. 3, the elements 3 have attraction surfaces 7 provided with attraction points 9 located in the lower edge of the hole 6 and adapted to reinforce the action of the surfaces 7. To facilitate cleansing the elements 3 are assembled in one unit by non-magnetic members 13 so that they can be withdrawn from the magnetic field, in this case produced by an electromagnet 11. In another form, Fig. 4, the permanent magnet is formed by a small parallelopiped 10 of material of high coercive power and the elements 3, placed between the soft.steel poles 2, are formed of appertured parallelopipeds, e.g. of trellis work filled with ferromagnetic metal filings 12. The element 3 in all the forms may be arranged fanwise in the air gap and may be formed by bodies in the form of honeycombs.

Title: Improvements in or relating to enamelled-wire electrical resistances of low ohmic value
IPC: H01C3/02
Filed: 1937-03-03
Abstract: 478,464. Wire resistances. S.E.C.I. SOC. ELETTROTECNICA CHIMICA ITALIANA. March 3, 1937, No. 6300. Convention date, March 3, 1936. [Class 37] A resistance support a is formed with a number of grooves on its periphery parallel to its axis and is turned down to a smaller diameter at its end portions c, d. Resistance wire is placed in these grooves and is connected to junction wires extending round the cylindrical portions c, d. The wires in all the grooves may be connected in parallel, as shown in Fig. 1, or each wire may be wound in zigzag fashion through a number of grooves as shown in Fig. 2, in which case one or more of the grooves may be left vacant. In order to prevent the wires from coming out of the grooves owing to expansion during the subsequent enamelling, a wire e is wound round the support, the longitudinal wires being insulated therefrom by being placed in insulating tubes f, Fig. 2, or covering them by insulating members at the crossing points. The use of the wire e may be obviated by turning down the support to a cylindrical section at a number of places so as to produce a number of short grooved sections which are individually wound, so that the sections of resistance wire are shortened and have less tendency to sag when heated. They are preferably held in turned-back lugs. The resistance elements are connected in series and may be differently wound so as to have different values. Tappings may be taken from the intermediate junctions.

Filed: 1924-03-15
Abstract: 236,977. Perry, C. E., and Evershed & Vignoles, Ltd. March 15, 1924. Morse and like code signalling transmitting arrangements employing a hand-operated generator, e.g. as described in Specification 175,720. The operation of the generator effects the opening and closing of the circuits at a pair of butt contacts in accordance with the signals to be transmitted. The shaft y, Fig. 1, of the generator a is driven from the handle B through the spur gearing shown, and a drum f, having its periphery shaped to represent the signals, is driven either through a worm wheel g and a worm e on the shaft of the pinion d or through a scroll drive. The movable butt contact n, co-operating with the fixed contact k, is carried by an arm l which is pivoted at m and is held by a spring p so that a pawl o on the arm bears against the periphery of the drum. Alternatively the signal representations may be arranged on the inside or at the edge of the drum, or the drum may be replaced by a movable band carrying corresponding projections, or the drum or the band may be provided with perforations corresponding to the signals and co-operating with a pivoted lever. To enable any desired message to be set up on a drum, the periphery may be provided as shown in Fig. 8 with a series of holes adapted to receive, removable pins 4. These pins co-operate with a pin or roller 6 on a lever 5 carrying the contact n, and the contacts n, k may be normally held together or held apart by a spring acting on the lever. Wireless signaJs may be transmitted on the spark system by arranging an induction coil, connected to the aerial through an oscillating circuit, in the circuit from the generator a through the contacts n, k and through the ordinary make-and-break of the coil. For continuous wave transmission the arrangement shown in Fig. 10 is used. The shaft y of the generator may carry, as shown in Fig. 7, a notched disc x co-operating with a pawl on a spring-controlled pivoted arm x to produce a high-speed make-and-break at contacts 1, 2, and this make-and-break replaces that of the induction coil for spark transmission, or is arranged in series with that at n, k, Fig. 10, for continuous wave transmission. A series of drums, each corresponding to a different series of signals may be provided with means for placing any particular -drum in operative position and for indicating which of the drums is so placed: The drums are adapted to be slid parallel to the shaft driving them to bring the desired drum into position to co-operate with the contact-carrying arm. The projections representing the signals are preferably on the inside of each drum, and a non- rotatable ring carrying indicating means is mounted in a groove on the outside of the drum, and is brought by the sliding movement into register with a window in the casing of the apparatus.

Title: Improvements in Embroidery Machines.
IPC: D05C3/04
Filed: 1919-03-20
Abstract: 124,739. Saurer, A., [Firm of]. March 20, 1918, [Convention date]. Embroidery machines.- Relates to apparatus for connecting and disconnecting the driving members of the tools of shuttle embroidery machines for the purpose of placing the tool into and out of gear at the will of the operator, or for stopping the tool automatically after a definite period such as a single, working cycle, and consists of a single trip mechanism for the tool driving member, which is controlled by at least two connecting and disconnecting members acting independently of each other whilst being so arranged that each can effect the connecting and disconnecting of the trip mechanism by directly influencing one sole trip device that serves as a coupling between the trip mechnism and its driving shaft. The application is shown to the shafts 5, 6, for driving the needles and borers, which are connected by a link 7 and crank-arms, The shafts are driven by an arm 8 with a sleeve 9 through which passes a rod 10 carrying a roller 11 tracking an eccentric groove in a disk 13 secured to the driving shaft 12 of the machine. The rod 10 has a pin-and-slot connexion with a lever 15 which carries a roller 25 tracking a cam groove 24 in a disk loosely mounted on a, transverse shaft 19, which is driven by a two-to-one reducing gear from the shaft 12, and has fixed to it a disk 22 provided with diametrically disposed notches 21. A spring- pressed pawl 26 on the cam-disk is adapted to engage the notches 21 and connect the cam-disk to the driven shaft 19. Two levers 35, 36 with tripping lugs 37, 38, are adapted to be moved by lugs 33, 34 on a rod 32 actuated by a small lever 27 on the handle of the pantograph controlling the work frame. In the ordinary working of the machine, the parts are in the position shown in Fig. 1, and to disconnect the shafts 5, 6 from the driving-shaft, the rod 32 is moved up, momentarily raising the lever 35, and releasing the pawl 26 which engages one of the notches in the disk 22. The cam groove 24 then moves the lever 15 to the left and disengages the roller 11 from the eccentric groove. A half revolution of the shaft 19 brings the pawl 26 into the position where it is again disengaged from the disk 22 by the lever 36. A lever 39 with a depending link 40 may be provided to hold the lever 35 with its lug permanently out of the path of the pawl 26 in order that the machine may be automatically stopped after each complete rotation of the shaft 19 corresponding to a complete working cycle of the tool shaft. In a modification, the lever 39 may be extended beyond its pivot and be provided with a hook member 44 adapted to withdraw the locking-pawl 45 from engagement with a ratchet 47 on the thread-brake. The pawl 45 is actuated in the ordinary use of the machine by a cam 50 and slide-bar 51. In this modification, the link 40 is made a suitable length to allow control of the thread-braking mechanism without affecting the lever 35.

Abstract: 491,728. Television ; type printing telegraphy. WHITE, E. L. C. March 10, 1937, No. 7062. [Class 40 (iii)] Pulses of long duration (e.g. frame synchronizing signals) are isolated from a mixture of pulses of long and short duration, by applying the mixture to two parallel paths, one of which comprises a delay network, so that on combining the outputs, the delayed and undelayed long pulses overlap to produce a signal distinguished by amplitude which is isolated by an amplitude filter. In the Figure, the two paths comprise valve 3, and delay network 7 and valve 4; the outputs are combined and the oscillator 5, operating as disclosed in Specification 402,629, is biassed to be controlled only by the derived pulses of greater amplitude. The delayed and undelayed pulses may be applied to the anodes of a double diode, Fig. 4 (not shown), or to the grids of a double triode, Fig. 5 (not shown), or may be applied to the two control grids of a hexode valve biassed to pass current only when both grids are energized, Fig. 2 (not shown) ; in this case, the mixed signals may also be developed in the output by a triode portion.of the hexode energized with the undelayed pulses. The invention is applied to television, the multiplex signalling system described in Specification 470,495, and typeprinting telegraphy. Specifications 420,391 and 455,375 also are referred to.
