Title: Materials testing control system
IPC: G01N3/06
Filed: 1966-03-28
Abstract: 1,094,468. Measuring stress and strain electrically. INSTRON CORPORATION. March 28, 1966 [Oct. 5, 1965], No.13673/66. Heading G1N. A control system for a materials testing device for measuring the stress (load) and strain on a specimen 32, held in grips 28, 30 between a frame 12 and crosshead 14, movable on screws 16, 18, by a motor 26 through gearing 20, 22, 24, comprises a strain sensing and control circuit and a load sensing and control circuit. The strain sensing circuit comprises an extensometer 34, mounted on the specimen, and mechanically coupled to a linear differential transformer 38. Signals from the transformer, representative of the strain in the specimen, are fed to a mode selector 48 via an isolation transformer 44 and amplifier 46. The strain control circuit, by which the strain in the specimen can be measured or controlled, consists of a transformer 50 identical to the transformer 38, an isolation transformer 52, amplifier 54 and a potentiometer 56, calibrated in units of strain, which also feeds signals to the selector 48. Similarly signals representative of the load on the specimens are fed from a load cell 60, via an amplifier 66 to the selector 48. Control signals are transmitted from a potentiometer 72 to the selector 48. In operation, either the strain or the load circuits feed a comparator 76, which compares the control and sensor signals, e.g. of the load circuit, and causes a signal corresponding to the difference to be transmitted to a motor control circuit 80, through amplifier 78, to adjust the crosshead. Simultaneously the sensor and control signals from the other circuit, e.g. the strain circuit, are transmitted to a comparator 74, the corresponding one of normally open gates 94, 94, e. g. 94, being closed, so that a signal representative of the difference between the two input signals is transmitted to the corresponding balance control circuit, e.g. 82, which mechanically adjusts the potentiometer, e.g. 56, to equalize the two signals. Thus the strain and load existing in the specimen at any one time are registered on the two potentiometers 56, 72.

[Also in Division E1] Articles are formed by applying a layer of powdered plastics material to a continuous heat conductive mould, heating the mould to completely fuse the layer, and subsequently cooling and removing the thus-formed layer. In one embodiment (not claimed), flat plates, e.g. tiles, are formed by applying powder to a mould 1, the side walls of which are adapted to carry bars 2a-2n from which reinforcements 3a-3n are suspended. The thickness of the tile is increased at the regions of the reinforcements, to ensure good anchoring thereof, by providing the mould bottom with recesses 1a-1n. Reinforcements having a higher melting point than the moulding material, e.g. metal ore, introduced before the powder is applied to the mould, whereas reinforcements of a lower melting point, e.g. plastics, are introduced after the moulding material has been melted, said reinforcements thus being actually fused to the finished tile. In the claimed embodiment powder is sprinkled from hopper 24 on to a moving continuous mould, formed by a steel belt 22 and side plates 23a-23n, and melted, under a heat insulating hood 32 by burners 25. The fused sheet thus formed is then cooled by air from head 27 and led to a take-off table 31 whence it is divided into lengths. Facilities may be provided to apply reinforcements to the sheet as in the not-claimed embodiment described above.

Abstract: 358,929. Inlaid linoleum. ARMSTRONG CORK CO., Lancaster, Pennsylvania, U.S.A.-(Assignees of Blenko, W. J.; P.O. Box 1020, Pittsburg, U.S.A.) May 8, 1930, No. 14145. Convention date, June 21, 1929. [Class 140.] In a rotary inlaying machine comprising a die roll 10 for cutting the material, fitted with strippers 13 for ejecting the scrap and the pattern elements, pins for actuating the strippers are controlled in order to obtain different patterns without altering the dieroll. As shown, the strippers are actuated by pins 22 in a scrap roll 20 and in a pattern roll 37. The pins are movable in the rolls and are brought into operative or inoperative positions during the rotation of the rolls by electromagnets controlled by a stencil switch or a rotary drum switch. The stencil is in the form of an endless web which may be changed as desired, and the repeat length of the patterns corresponds with the length of the web or a fraction of it. As shown in Fig. 3, the pins 22, which may be of brass or other non-magnetic material, are normally pressed outwards into operative position by springs 23, and in this position as the pin roll rotates collars 30 on the pins engage the outer periphery of a comb 29 as shown at 30a, whilst the pins engage and operate the strippers. This comb may be thickened in the central part as shown, to act as a cam and move the pins outwards. The pins 22 corresponding to strippers not to be actuated during any given revolution of the pin-roll are depressed by the head 32 of the armature of an electromagnet 34 so that the collar 30 comes beneath the comb 29, and the pin is held temporarily out of action. There is a magnet 34 for each circumferential row of pins. The pattern roll is similar to the scrap roll but the magnets are controlled so as to depress pins corresponding to those not depressed by the magnets of the scrap roll. In a modification Fig. 6 (not shown), the pins are normally held in the inner position by springs and are projected as required by electromagnets mounted in a fixed cylinder within the pin-roll. Stencil switches.--The circuits of the electromagnets are made and broken by a perforated endless web 49 of insulating material, such as heavy paper, passing over a rotating contact drum 45. A row of brushes 54 is mounted along an insulating bar 52 and connected with the row of electromagnets 34 for the scrap roll, and a similar set of brushes 55 is connected with the magnets 34a for the pattern roll.

Filed: 1943-09-01
Abstract: 593,459. Welding. BUDD MANUFACTURING CO., E. G. Sept. 1, 1943, No. 14274. Convention date, July 27, 1942. [Class 83 (iv)] In resistance electric welding non-arcing current of not less than 800,000 amperes per square inch and short duration is passed between electrodes placing the work under pressure so that heating to the welding temperature is confined within 25 per cent of the work thickness. The time is from 0.001 to 0.003 and is preferably 0.002 second, but times of 0.0005, 0.0001 and 0.00005 are referred to in connection with mild steel,. aluminium and copper, respectively. In the case of coldrolled stainless steel of the 18 per cent Cr and 8 per cent Ni type, the weld is made by the discharge of a 400 mfd. condenser charged at 1600 V. The area of the weld is 0.0275 square inch and the total electrode pressure used is 900 1bs., the welding-time being 0.001 seconds and the current 30,000 A. The welded metal is in thin disc form 17, Fig. 1, but may in some cases be annular. A.C. supply mains 21, Fig. 3, are connected to a rectifier 22 supplying D.C. to leads 27, 28, across which the condenser 26 is connected with a switch 25 on the charge side and a switch 30 on the discharge side leading to a stepdown transformer 29 supplying the electrodes 34. The welding time is a function of the square root of the product of inductance and capacity. Inductances 37, 38 or a resistance 39 may be connected as shown and oscillations after the first current impulse are suppressed by a device 40. The transformer should be of low magnetic reluctance and may be small enough for inclusion in a welding-gun so that short leads to the electrodes are possible. Specification 372,324 is referred to.
