IPC: C22F1/10
Abstract: 1,053,594. Making metal strip or sheet. SHERRITT GORDON MINES Ltd. Sept. 3, 1964 [Oct. 21, 1963], No. 36178/64. Heading B3A. [Also in Division C7] Nickel metal particles of a size less than 300 microns are fed into a conventional roll compacting unit to produce a green strip or sheet having a density less than 100% of the theoretical maximum density. The strip or sheet is sintered in a controlled atmosphere at 800 to 1150 C. to lower the sulphur content to below 0À003% by weight and the carbon content to below 0À005% by weight. One or more strips may be superimposed to form a thick laminated strip. Hydrogen is passed through the sintering furnace to desulphurize the metal and carbon dioxide or preferably water in the hydrogen removes the carbon. The sintered material is then hot rolled at a temperature about the recrystallization temperature of the nickel particles to increase the density to substantially 100% of the theoretical maximum. Stacked strips become fused together free from indication of lamination. The material is cooled under a protective atmosphere to ambient temperature and then cold worked to reduce its thickness. Finally it is heated to 650 to 980 C. and cooled to ambient temperature in a protective atmosphere. If the metal has cooled in air following hot rolling it is heated in a reducing atmosphere preferably hydrogen at 425 to 1200 C. to remove surface oxidation.

Abstract: 1,226,791. Radio-frequency systems; pulse radar. SOC. NATIONALE D'ETUDE ET DE CONSTRUCTION DE MOTEURS D'AVIATION. 29 Dec., 1961 [30 Dec., 1960], No. 46795/61. Headings H4D and H4L. A circuit for transforming short pulses into long pulses and vice versa comprises a delay line with regularly spaced taps to which are connected branch lines having specific individual gains, the gains corresponding to branch lines that are connected to taps located symmetrically with respect to the centre of the line being equal, and the branch lines being connected to an adding unit which produces an output proportional to the algebraic sum of its inputs. The long pulse is frequency-modulated symmetrically with respect to the centre time t 0  of the pulse, i.e. the instantaneous frequencies are the same at times t 0 t; the instantaneous amplitude is preferably also symmetrical with respect, to t 0 . In the radar system shown in Fig. 2 a short pulse from a generator D is fed to the input of delay line L, taps of which are connected through amplifiers to the addition unit A. The gains K 1 , K 2 , K 3  of amplifiers connected to taps 1, 2, 3 are respectively equal to the gains of the amplifiers connected to taps n, n - 1, and n - 2, the actual values of the gains depending on the desired frequency modulation law and on the attanuation of the line. The output of A is a long pulse which is amplified and possibly altered in frequency in unit B before being fed to the transmitting aerial G. Received signals from aerial H are amplified and possibly altered in frequency in unit C, and are then fed to the input of the line. These are long pulses, corresponding to the transmitted pulses, and are transformed into short pulses at the output of unit A, the latter being connected to the usual display apparatus X.

Abstract: 1,227,277. Thread cutting units. ATLAS COPCO A.B. 19 Aug., 1969 [10 Sept., 1968], No. 41336/69. Heading B3N. A power operated thread cutting unit has a housing 16, of a sliding vane rotary air motor, slidably but non-rotatably mounted in a cylinder 17 and carrying an adapter 18 in which a spindle 36 is axially movable relative to the adapter and carries a tool holder 15, the speed of the motor being controlled by the positioning of the spindle 36 relative to the adapter 18 so that the axial feed of a tap 10 is adapted to the axial feed of adapter 18. Drive, in an idling condition, to the spindle is via a member 50, dogs 53, 54, a clutching sleeve 38 and a ball 42. The motor exhausts through air holes 29, holes 32, passage 33 and gap 34, the latter acting as a restriction and thus controlling the speed of the motor. As the tap 10 advances toward a workpiece the gap is such that the motor rotates slowly. On contacting the workpiece, a spring 39 is compressed, thus opening gap 34 and increasing the motor speed. If, during thread cutting, the tap 10 tends to pull spindle 36 forwards with a speed exceeding the feed rate of adapter 18, a spring 40 is compressed and the gap 34 narrowed, thus reducing the speed of the motor. When the movement of the adapter 18 is reversed, either automatically or manually, the spring 40 is compressed as much as a stop sleeve 41 allows so that the motor speed is stopped or slowed down. Further retraction of adapter 18 causes a spring 59 to become compressed so that the dogs 54 of the clutching sleeve 38 engage dogs 58 of a gear sleeve 57. This sleeve is driven in a reverse direction by member 50 and gears 52. Whilst this occurs ring 35 passes flange 37 so that the gap 34 is transferred to the back of the flange 37, Fig. 6 (not shown), where it also controls the motor speed. Due to the gear arrangement the retracting is faster than the feed. When retraction is complete spring 59 forces the clutching sleeve back into direct engagement with member 50. To prevent axial sliding of dogs 54, 58 during retraction due to spring 59 the dogs can have tapered or rifled engaging surfaces. Air is fed to the motor through pipe 26, pipe 27 and piston-rod 25. The static forces on the spindle 36 from the spent air are balanced by a counteracting piston 45. Chamber 46 is under the pressure of the spent air whilst chamber 47 is at atmospheric pressure. Feed of housing 16 is controlled by a valve 14 which feeds air to a chamber 24 whilst venting a chamber 21. During feed motion a return piston 19 forces hydraulic fluid from a cylinder 20 to a reservoir 23. Retraction is by compressed air being fed to chamber 21 and chamber 24 being vented so that hydraulic fluid is forced from the reservoir 23 to cylinder 20 and thus piston 19 retracts housing 16. The hydraulic fluid flow may be adjusted to control the feed and retraction and the retraction may be at a higher speed than the feed. A stationary part 11  is adapted to be fixed to a frame. A portion 17a of cylinder 17 and adapter 18 may be replaced by a chuck for a drill.

Abstract: 1,265,095. Determining melt viscosity. BADISCHE ANILIN- & SODA-FABRIK A. G. July 18, 1969 [July 20, 1968], No.36231/69. Heading G1S. A device for cyclically measuring the melt viscosity of thermoplastics comprises a cylindrical tube within an oven 8 and having an orifice 18, a plunger 6 weighted by weight 4, chains 3 driven by electric motor 9 for raising and lowering the weighted plunger and switches S1, S2, S3, S5 operated by cams N1, N2, N3 on the chains or by the weight for controlling the movement of the chains. As the weight and plunger rise, cam N1 operates switch S1 which causes a fresh charge of predetermined weight from hopper 12 to be discharged into hopper 10 from where it runs down a channel 21, Fig. 2 (not shown) which is vibrated by an A.C. magnet, into the cylinder. The plunger then moves down until it rests on the plastic charge, cam N2 operating switch S2 to shut the motor 9 off. After a period determined by a time switch T2 during which the plastic is heated, the weighted plunger is lowered, and as cam N3 actuates switch S3, the beam 5 carrying the weight 4 is lowered by motor 9 so that the weight is carried by the plastic. As the weight reaches its lowest position it actuates switch S4 and the weighted plunger is then raised again to start another cycle. The rate of travel of the plunger during the test may be measured by an inductive device 13 actuating a pen recorder R, the paper drive of which is switched on by S3 at the beginning of the test and off by S5 at the end. Alternatively the time taken by the plunger to travel a given distance may be measured on time T 2  controlled by contacts on the weight. The weight 4 is exchangeable, and guide sleeve 3 may be releasably connected by a bayonet fitting to facilitate cleaning of the cylinder. (For Figure see next page)

Abstract: 1,266,039. Self-processing photographic apparatus. POLAROID CORP. June 19, 1969 [June 20, 1968], No.31131/69. Headings G2A, G2E].  In a film cassette 10, the film 22 can be driven from reel 32 to 34, or vice versa, past an exposure gate, and the cassette also contains exposure means which can be brought into operative relation with the film. The cassette is initially mounted in a camera for exposure of the film, and then transferred to a projector. The processing can be carried out before or after the cassette is mounted in the projector. The reels 32, 34 can engage with drive means in the camera or the projector. In Fig. 1 (not shown) the cassette is mounted in a motion-picture camera (14), and the film is driven from reel 32 to reel 34, past the exposure gate (25). When the film has been completely wound on to reel 34, the cassette is removed from the camera and placed in a projector 40, and the film is rewound from reel 34 to reel 32. Concurrently, it is subjected to the action of a processing liquid which is stored in a flexible sac 46 and fed through a tube 50 to an applicator pad 42. Flow and cut-off of the liquid is controlled by a valve 52 actuated by a lever 54, itself actuated by an arm 56. The pad 42 is mounted on a pivot, and is brought into contact with the film by being engaged by a right-angled extension 56b of arm 56. A second pad 60 removes excess liquid, and the film is further dried by hot air from a heater 68 which is forced through a vent 66. After the film has been completely rewound on to reel 32, the trailing end separates from reel 34, Fig. 3 (not shown). Manipulation by arm 56 and pad 60 causes this trailing end, now becoming the leading end, to be threaded between rollers 88 and 90. The film is now ready for projection, Fig. 4, which is effected by an offset lamp 92 and 45 degree mirror 100, this arrangement being for practical convenience. The film passes through a gate and the image is projected through the objective 102. Instead of being rewound on reel 34, the film now passes across a reel 128 to a take-up reel 118, whose hub 118a has a number of small permanent magnets 136 round its periphery and a number of hooks 138 centrally located. The leading end 22a of the film has a slot 140 and the leading edge has a strip 142 of magnetizable material. This is attracted by one of the magnets 136, so facilitating the engagement of a hook 138 in the slot 140. The film thus now winds on to reel 118. As the trailing end 22b of the film reaches reel 128, which also has a number of hooks 134 round its hub, a loop 144 at the end of the film engages a hook 134. When the film has been completely wound on to reel 118, and the drive reversed, the film now rewinds on to reel 128. This can be part of a separate cassette, in which the film can now be removed from the projector and stored. The entire projector 40 can be mounted within an enclosure having a system of mirrors for a rear projector screen, Fig. 12 (not shown).
