Filed: 1955-11-11
Abstract: 776,134. Electric motors. PHILIPS ELECTRICAL INDUSTRIES, Ltd. (Naamlooze Vennootschap Philips' Gloeilampenfabrieken). Nov. 11, 1955, No. 32302/55. Class 35. [Also in Group XXXVII] The turntable 5 for sound apparatus is driven by a direct-current motor having a stator coil 13 supplied with intermittent current through a vibrator 1, the stator having a number of poles 10, 11, 12 co-operating with teeth 4 made of ferro-magnetic material and situated at the rim of the turntable. The vibrator comprises a permanent magnet 2 secured to a spring-blade 3 for opening and closing contacts 6, 7, in accordance with the pitch and velocity of the teeth 4, the arrangement being such that the magnet 2 never touches the teeth. When the turntable is at rest, the magnet and one of the teeth are positioned opposite to each other, and the contacts 6, 7 are closed so that the motor is ready for starting. The spring blade 3 normally vibrates at its natural frequency, the contact 7 being mounted on a spiral spring to reduce damping. If the speed of the turntable tends to increase above the value corresponding to this frequency, however, the driving torque of the motor is reduced, so providing a stabilizing effect.

Abstract: 915,257. Drawing-wire. SYNCRO MACHINE CO. Sept. 8,1961 [March 10,1961], No. 32369/61. Class 83 (4). In a wire-drawing machine having a plurality of power driven rotatable drawing blocks, and a die assembly between each pair of blocks, means for guiding the wire from each block to the next die comprise a pair of fixed idler guide pulleys rotatable on a common vertical axis in an upper and a lower plane, and means for directing the wire from the upper plane to the lower plane. The machine includes a base 10, drawing blocks 12 and 14, each driven independently and wire guiding and loop forming assemblies 16 and 18. The assembly 18 comprises two idler guide pulleys 20 and 24 and a third guide pulley 22, mounted on a support 27 which slides in a track 28. An hydraulic cylinder 34 is fed with fluid at constant pressure and tends to move the pulley 22 away from the pulleys 20 and 24. Wire from the block 12 passes over the pulley 20, round the pulley 22 to the pulley 24 and through a die assembly 32 to the block 14. The speed of the motor driving the block 14 is continuously corrected by a variable resistor connected to a rack-andpinion mechanism associated with the cylinder 34, so that as the wire loop lengthens the motor speed is increased and vice versa. The die holder assembly includes a die-box 54 mounted on a vertical axis 56 and locked in any desired position by a nut 80 positioned between lugs 82 on a base member 74. The nut runs on a shaft 76 pivoted to the die-box. A similar arrangement comprising a nut 68 co-operating with lugs 66 on the die-box allows pivoting of the box in a vertical plane about a horizontal axis in the same vertical plane as the axis 56. The die holder assembly also includes a wirestraightening device comprising a guide roller 86 mounted on a bracket 84 and a roller 92 mounted on a pivoted plate 88, which is adjustably spring-biased to press against the wire. A cam 104 mounted on a lever 102 enables the roller 92 to be swung out for threading up the machine and then returned to a previously adjusted position.

Patent GB-797934-A (GB)
Title: Improvements in the preparation of titanium
IPC: C22B34/12
Filed: 1956-10-25
Abstract: The oxygen content of titanium is reduced by treatment with carbon and an alkali metal fluotitanate in which the valency of titanium is four at 780-1150 DEG  C. in an inert atmosphere.  The titanium is removed by filtration, the filtrate cooled, ground, and digested with 3 per cent Hcl for one hour.  A saturated solution of sodium fluoride is added until the colour changes from green to brownish violet, the liquor warmed to 40 DEG  C. to precipitate a lavender solid, heated to 90 DEG  C. and filtered to separate the lavender crystals.  The filtrate is cooled, treated with sodium fluoride until nearly colourless, warmed to 40 DEG  C. and filtered to remove a second batch of lavender crystals which precipitate.  Both batches of crystals are washed with distilled water and dried at 105 DEG  C. When the original treatment of titanium is performed at 780 DEG  C. to 900 DEG  C. the titanium of the alkali metal fluotitanate produced is three valent and when the temperature is 900 DEG  C. to 1150 DEG C. the titanium is two valent.ALSO:A method of deoxidizing titanium comprises heating titanium in the presence of carbon in a molten bath of an alkali metal fluotitanate in which the titanium is four-valent to a temperature between 780 DEG  and 1150 DEG C. under an inert atmosphere, and recovering the deoxidized titanium from the reaction mixture.  The molten bath may contain an alkali metal chloride as a diluent and the carbon may be in the form of lampblack, in amount, 2 1/2 mols carbon to each mol of oxygen in the titanium.  The titanium should be in pieces having large surface area to weight ratio and the fluotitanates should be of recrystallized purity.  The inert atmosphere may be argon.  Treatment may be for 2-10 hours after which the molten bath may be filtered and washed with water or dilute acids and then with alcohol to remove carbon and other solids from the titanium.  The oxygen content of the titanium may be reduced from 0.28 per cent to 0.06 per cent resulting in a reduction of Brinell hardness from 240 to 150.

Abstract: 1,112,630. Sliding clasp fasteners. OPTIHOLDING A.G. 30 July, 1965 [6 April, 1965], No. 32826/65. Heading E2S. A method of producing and applying end stops to uncut lengths of interlocked fastener strips i.e. tapes with fastening elements, wherein pieces 8a of thermoplastic film each oomprising the top stop for one fastener and a bottom stop for the next fastener in the length of interlocked strips, are welded by pressure and heat at positions along the said strips, comprises the steps of conveying a strip of thermoplastic film in the longitudinal direction of the length of the interlocked fastener strips to an end stop producing and applying station and at said station, for each position, cutting a said piece of film from the film strip and applying it and bonding it to the interlocked fastener strips, the cutting, applying and bonding steps being effected in one working operation. A machine is described for carrying out the method which comprises a welding tool having a male portion 1 and a female portion 2, a device for feeding the interlocked strips between the female portion and the male portion and a guide 11 extending in the direction of the length of said interlocked strips for conveying the strip 8 of thermoplastic film to a cutting nip constituted by the male portion of the welding tool and an edge of the guide 11, a downward stroke of said male portion serving to cut a said piece 8a of the said thermoplastic film extending from the guide therefore and to bond it to the interlocked fastener strips. The thermoplastic film is driven towards the welding tool by rollers 3, 4 and prior to entering the guide 11 slots having a transverse portion 9 and a longitudinal portion 15 are stamped out of the thermoplastic film by a punch 5, the punch 5 the male portion 1 of the welding tool and the rollers 3, 4 being synchronised so that the transverse portion 9 of each slot is so positioned that the male portion 1 only has to cut through narrow pieces of the film on each side of the transverse slot. The longitudinal portion of each slot forms a notch in the leading edge of the film so that when the next piece of film is welded to the interlocked strips it prevents the fastener elements underneath the notch being welded together, these being the fastener elements which are the elements adjacent the top stops of the finished fastener. After each piece of thermoplastic film has been welded into place the interlocked strips are advanced a distance corresponding to the length of the finished fastener before the next piece of film is welded into place. In addition to forming the top and bottom stops the welding tool also forms a slot 16 through the piece of thermoplastic film and the interlocked strips. The length of the piece of thermoplastic film can be of any desired extent. Reference has been directed by the Comptroller 900, 183.
