Abstract: 955,909. Ignition systems. ROBERT BOSCH G.m.b.H. May 11, 1962 [May 13, 1961], No. 18120/62. Heading F1B. In a spark igniter system comprising a permanent magnet excited alternator 11, which charges a condenser 32 through a rectifier 31, and an ignition induction coil 34 through the primary 33 of which the condenser is discharged upon closing of a cam-operated switch 18, at least two surges of charging current flow from the alternater to the condenser between successive closures of the switch 18. The alternater comprises a flywheel consisting of magnets 12 enclosed in a light metal rotary casing 14 connected to a hub 15 keyed to the engine crankshaft 16 and forming the cam operating the switch 18. The armature plate supports a first armature 22 feeding current to two lamps 25, 26, Fig. 2, and an ignition armature 30. On each revolution of the crank-shaft, two current surges flow from the armature 30 through the half wave rectifier 31 to the condenser which is discharged once per revolution. A second rectifier 41 damps out oscillating currents after discharge of the condenser 32 to protect the contacts of switch 18. In a modification, the protecting rectifier 41 is in parallel with the primary coil 33 and has a small condenser 42 associated therewith.

Abstract: 1,169,760. Propelling air cushion vehicles; rotary propellers. MINISTER OF TECHNOLOGY. 11 April, 1968 [20 April, 1967], No. 18141/67. Headings B7K and B7V. [Also in Division F2] In an air cushion vehicle the propeller unit comprises two blades 4 attached to a hub member in spinner 5 which is mounted for rotation about horizontal shaft 15 and arranged to pivot about vertical shaft 6, and at least one spanwise extending aperture formed in the surface of each blade for the discharge of a fluid stream over the blade surface. In the embodiment shown gas-turbine engine 11 drives the propeller through bevel gears 7, 8 at the upper and lower ends of the shaft 6 which extends through pylon 2 and air tapped from the compressor of the engine is led to the blades by way of a duct 12 coaxial with shaft 6, housing 14 in casing 3 and transfer ports 31, 32. The pressure of the air in each blade 4 lifts spring flap 13 for the air to be directed tangentially as a thin layer over the surface of the rearward part of each blade. Rapid reverse thrust can be applied without turning the pylon by a unit having the hub of Fig. 5 if each blade 4 has two oppositely-directed apertures closed by spring flaps 13, 34, Fig. 9. Air sacs 47, 48 bear on the under side of each spring flap and are connected to a source of air pressure through control valve 49, operation of which connects one or the other of the sacs to a pressure line 50. Rapid thrust reversal can also be applied by a unit in which the blades 4 are divided internally into two passages C, D by a longitudinal partition as shown in Fig. 6. The second aperture having spring flap 34 is connected to passage D within the blade, for which embodiment the hub arrangement is indicated in Figs. 7 and 8 (not shown). With propellers operating in water the fluid stream discharged from the blades would be water.

Filed: 1953-07-03
Abstract: 747,737. Magnetic compositions. PHILIPS ELECTRICAL INDUSTRIES, Ltd. July 3, 1953 [July 7, 1952], No. 18502/53. Class 38 (2). A permanent magnet having a (BH) max  value of more than 2.3 X 10<SP>6</SP> Gause-Oersted is made from crystals having a magnetoplumbite structure and of composition MO.6Fe 2 O 3  where M represents at least one of the metals barium, strontium and lead of which metals at most <SP>2</SP>/ 5  may be replaced by calcium, e.g. the compositions forming the subject of Specification 708,127, which crystals are powdered and, after the addition of a substance which inhibits crystal growth during heating, or a material which turns into such a substance during heating, converted into a magnetically-anisotropic body, e.g. as in materials forming the subject of Specification 747,724, and then heated to between 1150‹ and 1350‹ C. To produce a barium composition, barium carbonate and iron oxide are ground in alcohol, heated to 1250‹ C., cooled, reground, reheated and sintered at 1340‹ C., cooled and reground, 0.5 per cent by weight of lanthanum oxide as modifier is then added, followed by a liquid such as water, alcohol and acetone, and the mixture is compressed in a magnetic field, and reheated to 1200-1225‹ C. The grinding may be in water, and there may be only one heating to 1270‹ C. before the lanthanum oxide, to the extent of 0.25 per cent by weight, is added, the final heating being at 1320‹ C. The inhibiting substance may be 0.5 per cent of basic bismuth carbonate, 0.25 or 1 per cent of calcium carbonate and slightly different temperatures for heat treatment are specified. Times of grinding and rates of heating and cooling are specified together with details of the magnetic properties obtained. Other materials added as or to produce inhibiting substances may be barium sulphate, barium oxide, barium ferrite, calcium oxide, calcium ferrite, bismuth oxide, boric acid, arsenic trioxide or antimony pentoxide. In forming the magnetically anisotroped body the powdered crystals may be orientated in a magnetic field when, for example, they are suspended in an inert liquid which is subsequently removed by compression.

Title: Improvements relating to sawing and other like cutting machines for operating on moving bar or other stock
Inventor: PERRY JOHN BENSON
IPC: B26D1/60
Filed: 1961-05-23
Abstract: 937,777. Sawing. MIDLAND INDUSTRIES Ltd. Aug. 22, 1962 [May 23, 1961], No. 18509/61 Class 145. A flying saw machine comprises an endless saw or other cutting band 59 mounted on supporting pulleys 57, 58, at least one of which is adapted to be driven to drive the band, the band being arranged to provide an operative run 65 which is offset from a return run 63 in a direction of feed movement of the operative run so that the return run remains clear of a bar 20 being cut by the operative run. The pulleys 57, 58 are mounted on extensions 55, 56 from a slide 54 which is vertically movable on guides 53 upstanding from a carriage 29 guided for longitudinal movement in side plates 22 by balls 27. The carriage is secured to the upper run 31 of a chain 32 guided over sprockets 35, 36, the lower run of the chain being connected by a block 38 to the rod 42 of a piston- and-cylinder device 43. A member 76 depends from the slide 54 and has a follower 77 engaging a cam track 68 in an arm 68 which, at one end, is mounted on a pivot 70, and, at the other end, is connected to a piston-and-cylinder device 71 so that, when the arm is in its lower position, movement of the carriage causes downward movement of the slide to bring the saw into engagement with the bar 20 to be cut. The bar, which may be of synthetic resinous material issuing from a bar producing machine, is received between the conveyers 16 of a take-off machine 11, the lower conveyer 17 being driven by an electric motor 19. The motor also drives one member of a clutch 37 which is engaged when the forward end of a bar 20 engages a trip device 80 to drive the chain 32 so that the carriage 29 moves forward at the same speed as the bar. The arm 69 is, at this time, in its lower position so that the cam follower 77 draws the slide 54 downwardly firstly to cause spring- pressed clamps 50, 51 slidable in vertical guides 48 on the carriage to hold the bar and then to advance the operative run 65 of the saw through the bar, the operative run of the saw being guided so as to be in the plane of the saw cut by rollers 64 and backing rollers 73. At the completion of the cutting of the bar, the follower 77 actuates a trip device 40 to cause the device 71 to move the arm 69 upwardly about its pivot thereby raising the slide 54 to withdraw the operative run of the saw from the cut and lift the clamps 50, 51 to release the bar. When the bar 69 reaches its upper position, it actuates a trip device 74 to de-energize the clutch 37 and cause the piston-and-cylinder device 43 to return the carriage 29 to its initial position until a trip device 44 is operated to lower the arm 69 in preparation for the next sawing operation. The cut-off piece of the bar is discharged transversely of the movement of the bar to permit the leading end of the uncut bar to actuate the trip device 80 to initiate another cutting operation.
