Patent GB-731003-A (GB)
Title: Iron nitride of improved high frequency electro-magnetic properties
IPC: H01F1/36
Filed: 1953-03-16
Abstract: Iron nitride powder (see Group III) after treatment with aqueous phosphoric acid is mixed with furfural-formaldehyde resin in acetone, and the solvent evaporated.  The resulting grainy powder is mixed with a waxy lubricating powder, e.g. "Acrawax-atomized C" and moulded into cylinders.  The cylinders are cured at 170 DEG  C. and may be used as cores for transformers and inductance coils or in magnetic clutches and brakes. Urea-form-aldehyde or phenol-formaldehyde resin may be used in place of furfural-formaldehyde.ALSO:Iron nitride of improved high-frequency electromagnetic properties is prepared by heating iron powder, obtained by thermal decomposition of iron pentacarbonyl, at 350-450 DEG  C. in the presence of a gas mixture containing 60-90 parts by volume ammonia and 10-40 parts hydrogen for a period, e.g. 1-24 hours, which is sufficient to yield a powder having a nitrogen content of 4.8 to 5.8 per cent.  The treatment may be effected by passing the gas mixture over trays in a furnace at 3-15 cu. ft. gas flow per 100 lb. of iron powder at atmospheric pressure.  The gas mixture may include helium or nitrogen.  The nitride has an eddy current loss coefficient of 0.3 X 10-9 - 0.01 X 10-9 ohms/henry, cycles per second squared and a magnetic permeability of 6-13, has particles which are crystalline of the face centred cubic system with a lattice constant 3.8 A.U. (examples quote values 3.76 to 3.81) and are of spherical shape with a diameter 0.25-10m , and has a nitrogen content of 4.8-5.8 per cent and a carbon content 0.5-0.8 per cent, and resembles iron tetritanitride where a portion of the nitrogen may be replaced by carbon.  The nitride product may be milled and subjected to annealing.  The nitride powder may be treated with phosphoric acid and mixed with a binder, such as furfural-, urea-, or phenol-formaldehyde resin, and the resulting grainy powder mixed with a waxy material, moulded into cylinders, and cured at 170 DEG  C. to form cores for transformers and inductance coils or for use in magnetic clutches and brakes.  The powder may also be heated at 600-1200 DEG  C. in a nitrogen or nitrogen-ammonia atmosphere to produce sintered bodies for abrasive wheels, catalysts for ammonia synthesis, and screws, bolts or plates.

Title: Improvements in and relating to alternating current electric motors
IPC: H02K17/12
Filed: 1931-03-09
Abstract: 374,446. Induction machines. INTERNATIONAL GENERAL ELECTRIC CO., Inc., 120, Broadway, New York, U.S.A.- (Assignees of Allgemeine Elektricitõts-Ges. ; 2, Friedrich Karl-Ufer, Berlin.) March 9, 1931, No. 7289. Convention date, March 7, 1930. [Class 35.] The stator of a slow-running machine for polyphase current is formed with a number of groups of poles corresponding to the different phases, the poles alternating in polarity within each group; the rotor has a wave winding of uniform pitch so arranged that when one of the stator poles is directly opposite one of the rotor conductors the corresponding pole in the next group is separated from the corresponding rotor conductor by a fraction of a double pole pitch approximately corresponding to the phase difference between the two groups. In the arrangement shown the poles of a twophase motor are arranged in groups 1a, Ib, IIa, IIb, separated by spaces equal to 2¢ times the pole pitch; the pitch of the rotor winding b is equal to the pole pitch. In a modification the stator poles are uniformly spaced and the rotor pitch differs from the stator pitch by an appropriate amount.

Title: Apparatus for recording the result of gauging
Inventor: LOXHAM JOHN
IPC: G01B13/00
Filed: 1957-03-05
Abstract: 879,984. Recording pneumatic gauging operations. SIGMA INSTRUMENT CO. Ltd. June 4, 1958 [March 5, 1957], No. 7329/57. Classes 106 (2) and 106 (4). Apparatus for recording a plurality of dimensions of a workpiece gauged pneumatically, has a gauge providing a pressure corresponding to each dimension, which is applied to a displaceable member 24 against a control force to actuate a switch 26, 27 upon a sufficient displacement, means for varying, whilst the workpiece is being gauged, one of the forces acting on each displaceable member 24 and an interconnection between the varying means, switches and punching mechanism causing a hole to be punched in each column of a card in a position indicative of a corresponding dimension gauged. Each gauging pressure is fed through a pipe 23, Fig. 3, to the inside of a capsule 24 and the outside of each capsule is exposed to air under pressure controlled by a needle valve 31 which initially restricts leakage from the pipe 28 to hold the pressure in the boxes 25 high enough to keep contacts 26, 27 open. The cam 32 is rotated and progressively opens the valve 31, the pressure in the boxes decreases and the capsules 24 expand. In synchronism with the opening of the valve 31, bails 36 are driven and followed by spring-urged sectors 33 in the direction A. As soon as the gauging pressure in a capsule 24 overcomes the decreasing pressure in its box 25 sufficiently to close the contacts 26, 27, a corresponding electromagnet 47 swings a lever 42 to lock the sector 33 and with it a brush 38 sweeping over segments 39. The segment contacted thus depends on the dimension gauged. Recording follows with a card 1 moved in direction B, in ten steps if ten dimensions have been gauged, past a row of twelve punches 62, while a brush 68 moves in synchronism with the card over contacts 69 connected one to each of ten brushes 38. Common lines 59 connect corresponding segments 39 and punch operating electromagnets 64 so that in each longitudinal position of the card 1 a hole is punched in a transverse position across the card depending on the dimension gauged. In another embodiment, Fig. 7, there is a punch for each gauge, and the card is fed past the punches in synchronism with the step-bystep reduction of the control pressure, a record being made as and when the capsules 106 close the contacts 108, 109 in a position corresponding to the dimension. Specification 879,985 is referred to.

Title: Improvements in or relating to bale thrower
IPC: A01D87/12
Filed: 1963-02-25
Abstract: 967,422. Bale throwers. FIVE MANUFACTURING CO. Feb. 25, 1963 [March 16, 1962], No. 7462/63. Heading B5F. A bale thrower comprises bale throwing arms 18 driven through a throwing stroke and returned by gravity to a bale pick-up position, coupling means 38 for connecting a reciprocating member 36 to the arms 18, and bale sensing means 40 responsive to a bale at the pick-up position for effecting engagement of the coupling means 38. As shown in Fig. 1, hay is compressed in a chamber 44 by a plunger 12 driven by a crank 20 and the emerging bales 100 are thrown into a wagon (not shown) coupled to the baler. The bale 100 is gripped by holding means 34 on the lower ends of the arms 18 which are pivoted at 54 and moved from the full line to the chain line position (Fig. 6). The bale moves along a curved shoot 16 and is propelled by its own momentum when the arms 18 stop in the chain line position, the holding means 34 comprising spring-loaded dogs 60 (Fig. 2, not shown) which automatically release the bale. Operation of the arms 18 is effected by coupling them to a constantly reciprocating bar 36 connected by a link 142 to the crank 20. The coupling is effected by means of a trip 40 which is rocked upwardly about a pivot 102 by the emerging bale 100. A cam 108 carried by the trip 40 co-operates with a pin 104 carried by one of the arms 18 to move the arms 18 counterclockwise to the unlatched position (seen in full lines in Fig. 6). This causes a spring- biased pin (86 in Figs. 7 . . . 10, not shown) to enter a hole in the bar 36 to couple the bar 36 to a bifurcated arm 74 integral with the arms 18. After a bale has been thrown the arms 18 return to their latched position (Fig. 3, not shown) under gravity. Movement of the arms 18 is cushioned by a shock absorber 110. Figs. 11 . . . 13 (not shown) illustrate a modified form of coupling between the bale thrower and drive crank.

Abstract: 1,015,774. Liquid filters in parallel ; bypassing. ROSAEN FILTER CO. Feb. 26, 1963 [April 9, 1962], No. 7762/63. Heading BID. In a filter device having a primary and a secondary filter element, a valve is provided which variably increases the fluid flowing from the secondary filter element to an outlet as the primary filter element becomes clogged. As shown, a cylindrical housing member 10 has a cap member 11 mounted at one end, with a cylindrical boss 15 and at the other end an outlet 13 whilst the inlet is at 14. Mounted in the boss 15 is a rod 17 which carries a valve member 21 and an annular spacer 24 with magnets 23 at its other end. The primary and the secondary annular filters 37 and 38 respectively are mounted on either side of a ring member 36 which has a flange portion 39 and edge 40 whilst the other end of filter 37 is attached to a carrier 26 having a ring seal 28 to prevent fluid leakage. Filter 38 is attached to an annular member 32 having an O-ring seal 35 and being mounted on a surface 15C; the carrier 26, ring member 36 and member 32 are joined together and held in alignment by screws 33. In operation fluid enters at 14 and passes through filter 37 and out at 13 whilst the valve member 21 and flange 39 prevent fluid passing through coarse filter 38. As filter 37 becomes clogged, the pressure differential acting on flange 39 moves the filter carriage along against the action of a spring 30 and allows fluid to flow through filter 38. As the filter 38 clogs and the pressure rises further, the filter carriage moves further along until the annular member 32 is in a position to allow fluid to pass around guides 15A and thus by-pass both the filters. A device 45 for indicating the position of the carriage and the necessity for cleaning the filters may also be provided, which device is connected by mechanical links to the carriage at the annular member 32.
