Title: Improvements in or relating to bronzing machines
IPC: B41G1/00
Filed: 1920-08-14
Abstract: 171,478. Wade, H., (Gamse & Bro., H.). Aug. 14, 1920. Bronzing; gripper mechanism.-In a bronzing- machine, the sheets are carried by grippers to a bronzing-device, and are supported on a flexible apron resting on bridge-bars carried by chains passing round sprocket-wheels, the flexible apron travelling on the pitch line of the sprocket teeth. The sheets are transferred from the grippers of an offet press, and, after bronzing, are rubbed by reciprocating bars, polished by revolving and reciprocating rollers, and then delivered to grippers carried by delivery chains. A sheet x, Fig. 1, carried by grippers 4, 6 on the chains 1 of an offset press, is transferred to grippers 10, 11 carried by chains 14 passing round sprocketwheels 22, channelled bars 27 fixed to the chains supporting a flexible apron 28 fixed at its leading edge by a wedge 29, filling-piece 31, and bolt 30, Fig. 7, to the gripper 11, and similarly fixed at its trailing edge to a bar 27, and travelling on the pitch line of the teeth of the sprocket 22. The gripper 4 is fixed and the complementary finger 6 is rocked by a cam 8 fixed to the shaft 21<x> of the sprocket 21 in place of the usual cam. Similarly the gripper 11 is fixed and the, finger 12 is rocked bv a cam 16 which is mounted on the shaft 17 of the sprocket 22 and is adjusted by a threaded rod 16<1>. The sheets pass under a plush-covered bronzing roller 26 mounted in a hopper 32 provided with adjustable partitions 33 and a shield 32<1> for directing the bronze to the roller. The roller 26 is provided with a ratchet which is rotated intermittently by a cam-oscillated lever and pawl, an adjustable shield, covering some of the ratchet teeth, regulating the amount of rotation of the roller. The rubbing devices consist of two plush-covered plates 47, Fig. 5, adjustably suspended by bolts 46 passing through collars 45 mounted on rods 43 supported in bearings 44 and reciprocated by cranks. Springs 48, between the lower parts of the collars 45 and a plate 48 resting on the plate 47, retain the plush in position. The bronzed sheets are polished by four plush-covered rollers 59, Figs. 1 and 3<b>, three of which are mounted on spindles 60, carried in bearings 60a adjustable vertically by screws 67, rotated by a belt 62 and reciprocated out of time with each other by rods b, pivoted at c and oscillated by eccentrics 9. The fourth roller is fixed. The sheets are finally delivered to grippers carried by delivery chains. Fig. 8 shows a modified form of grippers which may be used in place of the grippers 10, 11, whereby a continuous flexible apron may be provided. One end of the apron 28 is fixed in a socket 10<a> in a gripper 10<b> hung on the shaft 12, Fig. 1, by a. bracket 10<c> and operated as before, the other end of the apron 28 being fixed to a complementary gripper 11<a>. Recesses 10<d> in the gripper 10<b> receive the fingers 4. As described in Specification 170,540, the machine is portable and may be coupled to an offset or other press. Specification 16965/09 also is referred to.

Abstract: 1,204,737. Ultrasonic inspection devices; transistor gating circuits. AUTOMATION INDUSTRIES Inc. 20 May, 1968 [7 June, 1967], No. 23829/68. Headings H3T and H4D. In an ultrasonic tester a multiplexing system allows several transducers to be used with a single transmitting and receiving circuit. The tester may be used for inspecting a workpiece at several locations or in several directions simultaneously or for simultaneously inspecting several similar workpieces, to determine workpiece thickness or the presence and depth of flaws. In the embodiment shown, operating in a pulse-echo mode, transducers 12, 14, 16. . . 18 are scanned over a workpiece and are energized simultaneously by pulser 26. Divider 10 provides control signals for opening emitterfollower gates 44, 46, 48. . . 50 in turn in successive repetition periods of pulser 26, to feed echo signals from the transducers to receiver circuit 36. Receiver 36 output is applied via adjustable time gate 94 to further emitter-follower gates 96, 98, 100. . . 102 which are opened at the same respective times as their corresponding gates 44, 46, 48 . . . 50 and which apply gate 94 output to associated alarms 76, 78, 80, 82. Meters, paint sprays, recorders or oscilloscopes may be used with or instead of the alarms. Diodes 28, 30, 32, 34 allow simultaneous pulsing (at high amplitude) of the transducers but prevent interaction between the (low amplitude) echo signals from the transducers. In an alternative embodiment, operating in a through-transmission mode, each transducer is replaced by a pair of transducers acting as transmitter and receiver respectively.

Title: Polyamide Tape and Power Transmission Belting
IPC: C08G69/36
Filed: 1967-05-23
Abstract: 1,170,638. Polyamide tape. E.I. DU PONT DE NEMOURS & CO. 23 May, 1967 [23 May, 1966; 19 Dec., 1966], No. 23833/67. Heading B5B. [Also in Divisions C3 and F2] A polyamide tape has a composition comprising 80 to 100% by weight of a copolymer of 70 to 92% by weight of hexamethylene adipamide units or units derived from caprolactam with 8 to 30% by weight, complementally to total 100% of said copolymer, of at least one different unit selected from hexamethylene adipamide, units derived from caprolactam, or hexamethylene sebacamide; and 0 to 20% by weight, based on the weight of said composition, of a plasticizer for said copolymer, with the proviso that the percentage by weight of said plasticizer plus the 8 to 30% units of the copolymer totals at least 15% of the weight of said composition, and the tape has a deformation ratio by roll orientation of at least 2 and a total deformation ratio of at least 3. Preferably, the copolymer is a copolymer of 75 to 85% by weight of hexamethylene adipamide and complementary to total 100% of said copolymer, 15 to 25% by weight of units derived from caprolactam. Specified plasticizers include N- ethyl toluene sulfonamide, 2-ethylhexanediol- 1,3, and tetramethylenesulfone. The deformation ratio, which is a measure of the roll orientation, is defined as the weight per unit length before orientation divided by the weight per unit (same) length after orientation. The total deformation ratio, where roll orientation is followed by stretching, is defined as the product of deformation ratio by rolling times deformation ratio by stretching. Preferably, the total deformation ratio is from 3À9 to 4À5. Tape may be rolled to obtain a deformation ratio by roll orientation of from 2À4 to 3À5 and then stretched to obtain the remainder of said total deformation ratio. Alternatively, the total deformation ratio may be obtained by roll orientation. Tapes so made may show tensile strengths of at least 2800 kg./sq. cm., preferably at least 3500 kg./sq. cm., and are suitable for lamination to a wear surface material to make a power transmission belting. The tapes are obtained by orientation of ribbon-shaped polyamide billets having the above-described composition. The billets can be made by extrusion or by the moulding process of Specification 1,170,640. Orientation of the billet is carried out by passing it between at least one pair of orienting rollers as disclosed in Specification 1,017,175. This orientation is called roll-orientation. In another embodiment, roll-orientation of the billet can be combined with subsequent stretching to produce tapes having the above-described strengths and dimensions.

Abstract: 663,772. Telegraph receivers. WESTERN ELECTRIC CO., Inc. Sept. 23, 1948 [Sept. 29, 1947], No. 24908/48. Class 40 (iii). [Also in Group XIX] A magnetic signalrecording device comprises means operable in response to a signal to produce contact between a magnetized pin and a magnetizable record carrier movable relatively thereto, so that the signal is represented on the carrier by the magnetized region resulting from said contact. When a key K, Fig. 1, is depressed it energizes a magnet M whose armature A brings a magnetized pin P, preferably of high retentivity, into contact with a magnetizable tape T which is moved in the direction of the arrow by a drum D. By suitable manipulation of the key K intelligence may be recorded in the magnetic tape by the length or spacing or both of the magnetized spots produced by the pin P. The key K may be depressed for equal lengths of time while the speed of the tape T is varied, to produce magnetized spots of varying lengths, or the key may be depressed while the tape is stationary, the spacing of the magnetized spots being determined by the distance through which the tape is moved between each key depression. The tape may be overlaid with paper or coated with an iodine compound so that when the pin P is in contact current passes through to the earthed drum D and burns a hole in the paper or discolours the coating. The key K may be operated by hand or by any suitable means and the tape may be replaced by a disc, card or other form of magnetic medium. A plurality of magnetized pins P may be employed, each arranged to contact the tape in its own individual path. In an embodiment adapted for printing telegraphy the magnetic pins P<SP>1</SP>, Fig. 2, are arranged in a helix around the type-wheel shaft S. When, in known manner, the typewheel is positioned with a particular letter opposite the tape T<SP>1</SP> a corresponding pin is also brought opposite the tape. When, in the usual way, a printing bar PP is raised, the tape T<SP>1</SP> is pressed against the type-wheel and a magnetizable portion of the tape is pressed against a corresponding pin P<SP>1</SP>. The transverse position of the resulting magnetic spot indicates the letter printed. The tape may be covered with a current-responsive layer as already described and the type-wheel PW may be omitted.
