Title: Improvements in or relating to apparatus for straightening wire
IPC: B21F1/02
Filed: 1959-11-23
Abstract: 909,192. Straightening by skew-rolling. FITCH, C. K. Feb. 23, 1961 [Nov. 23, 1959], No. 36032/59. Class 83 (4). Apparatus for straightening wire comprises either a pair of waisted skew rolls rotatably mounted on a carrier and means to effect relative rotation, between the carrier and a reel of wire to be straightened, about the axis of the wire passing between the rolls, or a single pair of waisted skew rolls formed on their surfaces with encircling ribs and rotatably mounted in fixed bearings. Shafts 28 of skew rolls 11, 12 are mounted in bearings in a carrier 14 rotated, about the axis of wire 13 passing therethrough to be straightened, by a pulley 8. The roll shafts 28 carry pinions 29 engaging a fixed internal gear track 30 to rotate the rolls about their own axes. To adjust the rolls angularly relative to one another and, simultaneously, their distance apart, the roll shafts 28 are mounted in spherical bearings in blocks 31 movable radially in guides 43 formed in annular discs 35a, 35b rotatably adjustable in opposite senses relatively to the carrier 14 by pinions 37 driven by a shaft 39. Such angular movement also causes pinions 33, threaded on extensions 32 of the blocks 31, to roll on adjustable arcuate gear tracks 34 on the carrier 14, thus to move the blocks 31 radially. The angular and the distance adjustments could be effected independently. The rolls need not be positively rotated, means then being provided to pull the wire through a wire storage reel 26 may be rotated about the wire axis and the carrier 14 fixed. The carrier 14 may be fixed and the rolls driven and formed with ribs to feed the wire through. The rolls may be formed with continuous helical ribs 42, Fig. 6, or with intermeshing circumferential corrugations, Fig. 7.

Fig. 2, adapted to be cocked by a lever 13, and a drum magazine 17 for supplying shots to the barrel I when the piston is cocked, and consists mainly in arranging the magazine to be operated simultaneously with the piston by the same cocking lever. As shown, the lever 13 is pivoted at 14 and is connected by a link 7 to a long arm 6 on a valve 5 provided with a short arm 8 carrying a spring plunger 9 adapted to operate on ratchet teeth 20 around a drum magazine 17, see plan, Fig. 4. This magazine has pockets 19 for the bullets and is rotatably mounted on a stud 18 over a plate 21; and a cover 24 is rotatably secured on the magazine by a screw 25, spring ring 30, 31 being interposed to prevent looseness and accidental displacement of the rotatable parts. The cover 24 has a series of holes 29 corresponding to the chambers 19 in the magazine and can be set in either of two positions determined by a spring catch 26. In one position, the holes in the cover open the chambers 19 and enable them to be filled; in the other position, the holes in the cover are partly out of register with the chambers 19 and prevent the bullets from falling off while allowing them to be seen. When the lever 13 is swung back to cock the air piston 3 in the known manner, the valve 5 is rotated and turns its port 33 vertically below the magazine, which is simultaneously rotated and drops a shot from a chamber 19 into the port 33 of the valve. One the return of the lever 13 to the folded position against the barrel, the valve 5 turns its port 33 into axial alignment with the barrel 1 and the air cylinder 2. The gun is thus loaded and cocked and ready for discharge.

Abstract: 843,473. Automatic frequency control. PYE Ltd. Nov. 18, 1957 [Nov. 27, 1956], No. 36253/56. Class 40(5). In an arrangement for maintaining constant the spacing of the video (196.25 mc/s.) and audio (201.75 mc/s.) frequencies transmitted by a television transmitter, their frequency difference (5.5 mc/s.) obtained from a mixer to which they are applied is mixed with a reference frequency (4.5 mc/s.) from a crystal oscillator V9 in a second mixer stage E, and the output is supplied through an amplifier G to a discriminator H wherein variations in the input frequency from 1 m/c. develops a D.C. control signal. The discriminator includes networks R1 C1 whereby the effects of the audio frequency modulation is eradicated from the output to terminals a, b which are connected to similarly labelled terminals in the input to a free-running reactance modulated oscillator B which produces 1/36 of the final sound carrier. The audio signal which is frequency modulated on the carrier is applied to oscillator B over socket P1, transformer Tl, and cathode follower stage A and the output from B after frequency multiplicator in unit C is fed to succeeding stages of the transmitter (not shown) from output socket P2. A further crystal controlled oscillator K (5.5 mc/s.) operable by switch S2 and relay RA permits calibration of the discriminator and a meter M wherein the frequency error signal may be indicated. The meter M may be switched to measure the audio modulation or the RF output. A relay RP in the anode of a valve V13 which is held non-conducting when the spacing is correct opens the discriminator output circuit if the 1 m/c. signal fails and operates alarms. Manual regulation guided by the meter reading is included.

Title: Improvements in the galvanizing of steel or iron sheets
IPC: C23C2/00
Filed: 1928-12-08
Abstract: 318,806. Maliphant, G. S., and Rees, F. J. Dec. 8, 1928. Galvanizing. - In galvanizing pots comprising a lead bath and a spelter bath the lead bath is formed so that a portion of the surface of molten lead, preferably of small area, is isolated from the main lead surface. The plates to be galvanized are carried by guides through the main portion of the lead bath and out at the isolated surface which is in the spelter bath and is covered with a layer of spelter sufficient to complete the galvanization. The plate receives its lead coat before coming into contact with spelter or dross and, the area of contact of the lead and spelter being small, very little dross accumulates in the path of the plate when leaving the lead bath, the passage of the plate helping to displace any accumulated dross which sinks to the bottom of the spelter bath. A partition 4 divides the pot into two compartments 2 and 3 containing spelter and lead respectively. The partition has an aperture 5. over which is fitted a chamber or trunk 6 at the upper end of which is the isolated lead surface 13, below the spelter surface 9. The plates are guided by bars 10 through the main lead bath, the trunk, and the layer of spelter above the lead surface in the trunk. Modifications of the construction of the partition are represented in Fig. 4, in which the main portion of the lead bath is a continuation of the trunk and may be detachably secured to or formed integrally with the spelter bath. Other modifications of the construction of partition are described.
