Title: Improvements relating to the joining or connection of parts by fusing
IPC: B23K11/30
Filed: 1936-09-19
Abstract: 467,308. Welding ; soldering ; making cased articles. DENNEEN, F. S., and DUNN, W. C. Sept. 19, 1936, No. 25506. [Classes 83 (ii) and 83 (iv)] Metal surfaces are joined by fusion produced by radiation or electrically induced currents, the welding taking place in an inert or reducing atmosphere, one or more current conductors being opposed to or applied to the work and being arranged substantially parallel thereto or conforming to the shape of the work. Pressure may be applied to the surfaces during the heating operation and after fusion the surfaces may be quenched by cooling fluid. High frequency currents may be employed for electrically inducing currents in the work. As shown in Fig. 1, a plate 1 is joined to a body 2 with the aid of a heating element 3 to which high frequency current may be applied by conductors 4. At the termination of the heating, pressure is applied through the medium of a shaft 8, eccentric 6, sliding block 7 and yoke. Quenching fluid may be introduced to the work through apertures 5. In Fig. 12 is shown a construction which enables shells 58, 59 to be fused to a shaft 60. Heating elements 61, 62 are hinged at 63, and preferably are insulated at 63<1>. Copper gauze or the like impregnated by a plastic conducting substance such as an amalgam of tin and mercury is placed at 64 for ensuring a circuit connection close to the shells at the joint between the heaters. Plungers 65 actuated by springs compress the shells against the shaft. Valves 68, 69 introduce gas for maintaining required atmosphere. When rapid cooling is desired for hardening the shells after fusion the valves stop the influx of the gas and admit water or other cooling medium. Specifications 234,373, [Class 83 (iv)], and 385,285 are referred to.
Patent GB-1146083-A (GB)
Title: Method of, and apparatus for, cold shaping sheet metal stock
IPC: B21D25/02
Filed: 1966-06-08
Abstract: 1,146,083. Stretch forming. CYRIL BATH CO. 8 June, 1966 [16 Dec., 1965], No. 25510/66. Headings B3E and B3Q. A method of stretch forming sheet metal over a male die 5 comprises gripping a pair of opposed margins of the stock while leaving free the remaining pair, and controlling movement of the gripped margins by respective restraining links 60, 63 to tension the stock above its elastic limit. A press for carrying out the method is similar to that described in Specification 1,029,755, except for the controlling links 60, 63 and the grippers 30, Fig. 4, which are operated, through links 33, 34, by hydraulic cylinders 36. Additional guide rolls (58, Fig. 2) are also provided for the carriages 50 carrying the grippers. At each end of the carriages 50 is pivoted one end of a link 60, 63 the other end of which may be pivoted on the lower die 5. As elevators 20 supporting the carriages are lowered by hydraulic cylinders (22, Fig. 5), the links 60, 63 move the gripper-carriages apart, thus tensioning the work, which is strained beyond its yield point before or after encountering the die 5. The tension may be maintained until the dies are closed. The hydraulic pistons 80 for moving the linkcontrolled carriages to tension the work, as described in the prior specification, may be retained, and their cylinders drained or used as shock absorbers. The die 5, carriages 50, links 60, 63 and jaw units 30 may be removed from the press as a unit. In a modification, Fig 10, the carriages are lowered by push-rods 117 on the slide 113 of a mechanical press, or described in Specification 1,010, 408. In a similar arrangement telescopic, hydraulic push rods (128, Fig. 11) are used which are connected to relief-valves. The power means for lowering the carriages may be applied to the links 60, 63.

Abstract: 335,341. Harootniain, O. Aug. 22, 1929. Ironing - presses. - A perforated peripheral steaming channel 28, Fig. 4, and transverse perforated channels 31 communicating therewith at their ends are provided in the press head 25 which is heated by electric heating elements 33 the cover 32 for which is covered and lined with heat insulating material. The supply of steam is controlled by a valve 40 having an operating lever 42 mounted on the handle 34 of the press head on which the switch 37 for the heating elements also is mounted. The press head is rotatable about a vertical support 14, Fig. 1, and is normally pressed downwardly by springs 21 to contact with the buck 51 through an intermediate pressing cloth 61 carried by a frame 60 rotatably mounted in an arm 55 pivoted to a bracket 54, Fig. 10, on the work table 11. When the press head is swung away from the buck and a pedal 69, which is linked to the arm 55, released, a spring 71 rocks the arm 55 and raises the frame 60 whilst at the same time a cam 65 acts on a roller 63 on an arm 62 moving simultaneously with the frame to tilt the frame against a spring 64 out of its normal plane and to a position as shown in Fig. 1. The frame may be manually swung and tilted still farther and then be supported by a hook 67 at the end of the cam 65.

Abstract: 159,916. Penn, W. F. July 31, 1920. Vertical-cutter type for cutting sheet material in direction of feed; rotary type for cutting rectilinearly. - Relates to apparatus for dividing rolls of paper into sheets by first cutting the rolls into strips, superposing these by passing them over guiderods inclined to the travel of the strips to change the direction thereof and finally severing the superposed strips transversely into sheets. The apparatus is particularly applicable for cut. ting paper bearing rows and columns of watermarks, means being provided for adjusting the strips so as to bring the respective water marks into coincidence, before division into sheets is effected. The paper b is fed from a roll to cutters or knives d, shown as pairs of co-operating rotary knives, which sever it into strips b<1>, b , these being led beneath inclined guides e, adjustably mounted by bolts moving in slots in the framing, thus allowing the strips to be superposed and to move in a direction inclined to that of the sheet. The strip b<1> passes directly over a guideroll j to the feed-rolls f, but, in order to allow the water marks on the other strips to be brought into coincidence, the strips b<2>, b<3>, b<4> are previously led over guide-rods k<2>, k<3>, k<4>, and looped over rollers m<2>, m<3>, m<4> capable of longitudinal adjustment by means of screws o rotated by bevel-garing through hand-wheels q. From the guide-roll j and feed-rolls f, the strips pass to a rotary blade cutter s co-operating with a block r, by means of which severance into sheets is effected.

Abstract: 1307142 Magnetic tape data storage; skew correction COMPAGNIE INTERNATIONALE POUR L'INFORMATIQUE 19 April 1971 [8 April 1970] 26270/71 Heading G4C A multi track magnetic tape read out device includes means for compensating for dynamic skew of characters recorded in parallel during read out. By dynamic skew is meant dispersion with respect to time of the read out bits as a result of a zig zag movement of the tape with respect to the average portion defined by the tape guiding means adjacent the read out heads. A first means detects the actual conditions of relative occurrences of at least the first bit significant pulses of successive characters with reference to the normal read out period of said characters; and second means responsive to the detected conditions correspondingly vary the length of the assembly periods for said characters. The data is recorded using NRZ coding.

Abstract: 1510322 Digital-to-analogue conversion DEUTSCHE TEXACO AG 20 June 1975 [22 June 1974] 26402/75 Heading H3H Data digitally stored in the form of mantissa A and exponent E to integer base B is converted to analogue signals, compression being obtained by varying the reference voltage V ref  of a digital to analogue converter 14, the reference voltage being derived by sampling at a time determined by the data a sawtooth reference voltage that rises in each cycle from an initial value to a final value B times the initial value. In Fig. 1, coarse and fine compression is employed: for coarse, the mantissa is shifted in register 13 according to the difference between E and the state of a counter 20; for fine, V ref  is varied by algebraic summation at 16 of the averaged output of the digital to analogue converter, the value of V ref  used for the previous conversion cycle and a ramp voltage which may be linear or exponential, to define a time at which the reference sawtooth, which is exponential, is to be sampled. There may be several sawtooth cycles for each conversion cycle, the actual reference cycle sampled being used to control the counter 20 in the coarse loop.
