IPC: E02D5/04
Filed: 1921-10-11
Abstract: 191,461. Williamson, J. Oct. 11, 1921. Piling.-Metallic sheet piling is rolled in sections of dished form with straight end portions B, Fig. 1, the outer edge of each end portion terminating in a hook-like formation C, the outer edge D of which is bulbous and terminates a short distance from the plane of the faces of the straight portions B. Two such sections are riveted together with the portions B in contact, as shown in Fig. 3, so as to form at each edge C-shaped portions which interlock with the C-shaped portion of a similar double section F or with the hook-shaped end of a single section E. The bulbous edge D fits loosely in the groove of the hook C, but will not pass through the opening of the C-shaped end portion of the double section, so that the joint is flexible, but separation of successive sections is prevented. A line of piling is built up wholly of double sections or partly of double and partly of single sections. The section may be combined with channel or other structural sections as shown in Fig. 6. According to the Provisional Specification, a line of piling may be constructed from sections with the dished portions arranged alternately in opposite directions, the two meeting straight portions of adjacent sections being riveted or otherwise fastened together.

Title: Improvements in or relating to transducer devices
IPC: G01P15/097
Filed: 1962-07-13
Abstract: 1,011,775. Electric selective signalling. LITTON INDUSTRIES Inc. July 13, 1962 [July 14, 1961], No. 26978/62. Heading G4H. [Also in Divisions G1 and H3] In a transducer, a pair of elongated, bifurcated, rigid vibratory elements are oscillated about their longitudinal axes at or near their natural frequencies, and a force to be measured is applied to the elements in the sense to reduce the oscillation frequency of one element while increasing that of the other, and the changes of oscillation frequency are measured. As shown, Fig. 4, two piezo-crystal elements, 11a, 11b, are connected in the frequency-determining circuits of oscillators 31a, 31b, which may be transistorized Meacham bridge stabilized oscillators. Elements 11a, 11b are subjected to a common force, e.g. an acceleration, so that 11a is compressed and 11b experiences a tensile load, the frequencies of oscillation of oscillators 31a, 31b then being w 1 , w 2  respectively. The outputs of the oscillators are fed to a mixer 36, the output of which has a frequency (w 2 -w 1 ) and is applied to a counter 38, which is periodically reset by a reset circuit 40, to produce a digital signal representing the applied force. It is shown in the Specification that (w 2 -w 1 ) = 2KS/(w 2  + w 1 ), where S is the magnitude of the applied force and K is a constant; therefore, if (w 2 +w 1 ) is kept constant, e.g. at twice the unloaded frequency of one element (preferably the elements have equal natural frequencies when unloaded), (w 2 -w 1 ) is directly proportional to S. This is achieved by adding w 1  and w 2  at 33 and comparing the sum with a reference frequency, generated at 42, in a comparator 35 whose output, which represents the frequency difference #w, is amplified at 37 and used to apply such compressive or tensile forces to elements 11a, 11b, as to reduce #w substantially to zero. If counter 38 is not periodically reset it will indicate velocity. Transducer construction.-Fig. 1 shows an accelerometer in which accelerations of a frame 10 along three mutually orthogonal axes, X, Y, Z, differentially load the elements of pairs of high-Q quartz elements 13a, 13b and 11a, 11b and 15a, 15b respectively. Each element is fixed between frame 10 and a mass 17 or 19, and comprises two parallel bars 21, 23, Fig. 2a, joined at their ends. Conductive coatings 25, 27, 29 enable each element to be connected in the circuit of an oscillator 31. Alternatively, the elements may be made from a plurality of pieces of quartz &c. cemented together. Fig. 5 shows a modified accelerometer comprising only one mass 17. Analogue-to-digital converter. Fig. 7.-An analogue signal fed to coil 55 exerts a force on a magnetic mass 53, differentially loading elements 51a, 51b which are connected in a circuit such as that shown in Fig. 4.

Filed: 1934-09-20
Abstract: 444,491. Welded joints. ROHRSCHWEISSMASCHINENGES., 56, Grafenberger-Allee, Dusseldorf, Germany. Sept. 20, 1934, No. 27104. Convention date, Sept. 22, 1933. [Class 83 (iv)] In a process for the resistance welding of joints such as the longitudinal seams of pipes in which the seam to be welded is first preheated under an electrode roller by a current which flows longitudinally relative to and not directly across the seam, the edges of the seam are smoothed and matched by the simultaneous pressing together and preheating, then separated from each other and melted between two electrode rollers located on opposite sides of the seam, and thereupon being again pressed together and conveyed, if necessary, to a compensating means, the supply of current to which is in interdependent ratio to the current supplied to the preheating roller. A pipe 1 fed along by rollers 5, 6 and 7 is preheated by the roller electrode 2 and the edges of the seam matched, the seam is allowed to open slightly as the pipe passes the welding electrodes 3, Fig. 3, and the final compensating heating operation is performed by the roller electrode 4. The electrodes 2 and 4 are both connected to the same supply phase a, Fig. 1a, of a three-phase supply so that their current supply is stated to be in interdependent ratio, they are mounted in adjustable spring-closed split bushes (not shown), carried by vertically adjustable spring- pressed brackets 13, 14 which are attached to longitudinally adjustable carriages 15, 16, the latter allowing the ohmic resistance of the preheating and compensating circuits to be varied by altering the operative length of pipe. The welding electrodes, Fig. 3, are carried in adjustable spring-pressed split conical bushes 17 forming part of the conductors, these ensure that the face of the electrodes is drawn lightly against the conductor. The current supply to these electrodes is taken from the phases band c of the supply.

Abstract: 994,537. Turbine blade mounting. BROWN, BOVERI & CO. Ltd. July 9, 1963 [July 11, 1962], No. 27110/63. Heading FIT. A method of fitting steam or gas turbine blades 3, having abutting parallellogram shaped tip shrouds 4 and fir-tree roots 1 in a circumferential channel in the rotor comprises introducing the roots of all but the last blade into the rotor channel and applying a twist to the blades 3 so as to reduce the space occupied by their shrouds 4 in the peripheral direction. The twist is applied to the blades 3 by a stirrup comprising a sector 9, offset screws 10 and an observation hole 13. Each pair of opposing screws 10 bears upon a wedge 11 mounted in a transverse groove in a temporary extension 4a of the shroud 4 of each blade 3 so as to exert a twisting movement upon the blade. Each stirrup covers about five blades 3 and successive segments of blades are acted on by a number of stirrups until all the fitted blades have been twisted to the required angle. The last blade is then fitted in the groove and divided spacing wedges 7 fitted between it and the roots 1 of adjacent blades and between the remaining blades. Wedges 11 are removed and shroud extensions 4a machined away. The construction effects vibration damping.

Abstract: 1,218,830. Variable denier synthetic yarns. IMPERIAL CHEMICAL INDUSTRIES Ltd. 19 May, 1969 [12 June, 1968], No. 27906/68. Heading B5B. Variable denier yarns of synthetic polymers are produced by drawing undrawn yarn between feed and draw rolls set to rotate at different speeds defining a draw ratio lower than the " natural draw ratio " across a " neck " of the yarn, and causing the yarn in the span between the feed and draw rolls and a heat source consisting of a portion of a flame or hot gas stream intermittently to come into close proximity or contact with one another according to a programme so as to form " necks " in the yarn. The yarn may be moved into and out of contact with the flame or hot gas stream, e.g. by means of passing the yarn through guides on an electro-mechanical vibrator controlled by a signal generator. Alternatively the flame or hot gas stream may be deflected into and out of contact with the yarn, e.g. by means of a jet of compressed air modulated by a fluid logic element controlled electromagnetically. In both cases the movement is controlled according to a programme which may be periodic or pseudo-random, e.g. by means of periodic or pseudo-random pulses from the signal generator. The yarn thus produced has thicker portions or nubs of lengths and spacings corresponding to the pulse lengths and spacings of the programme. Typically, mean nub lengths are 1-25 inch, mean nub spacings are 1-100 inch, and the mean nub peak denier is 1À2 to 4 times the denier of the thinner sections. Preferred polymers are polyhexamethylene adipamide (nylon 6À6) and polyethylene terephthalate. Examples of production are given.
