Title: Tightening system and method and fastener assembly usable therewith
IPC: B25B23/14
Filed: 1975-09-19
Abstract: 1526947 Measuring axial load on bolts electrically STANDARD PRESSED STEEL CO 19 Sept 1975 [19 Sept 1974] 38497/75 Heading G1N [Also in Divisions B3 and G3]  In a system for tightening a bolt 58, Fig. 5, to a desired axial load Td, a special washer 64, located between the bolt head and the members 54, 56 to be clamped together, is formed with a projecting pad 70 which yields at a known axial load Lp, the collapsed pad flowing into a groove 72. The torque applied to the bolt by a wrench 12, Fig. 4, powered by a pneumatic motor 14 is continuously measured by strain gauges 25 and the torque/rotation gradient is determined in comparator 34 with the aid of a toothed member 26 on the motor shaft and a pickup 28. When the projecting pad 70 of washer 64 collapses the torque/rotation gradient falls to 50% or less of the maximum gradient, stored at 36. The instantaneous torque value Tp when this occurs is fed to calculator 42 together with the known axial load Lp at which this occurs, stored at 44, and the desired axial load Ld, stored at 46. The calculator combines these signals to determine the torque Td which will give the desired axial load Ld. The increasing instantaneous torque developed by the wrench is fed to comparator 50 together with the desired torque Td. When these are equal the output from comparator 50 closes valve 20 to stop motor 14.

Abstract: 1,184,317. Programming jump instructions in a computer. TELEFONAKTIEBOLAGET L. M. ERICSSON. 21 Aug., 1968 [31 Aug., 1967], No. 40088/68. Heading G4A. A computer having first and second registers, an instruction memory and a programme counter for selecting instructions is arranged to jump to a selected instruction sequence among a plurality of such sequences in the memory, the jumps being controlled by one single jump instruction consisting of an operator and a variable part, and subtracts a fixed number in the variable part from the jump instruction address to obtain a prior address which is stored in the first register, chooses a second address by adding the jump instruction address to the contents of the second register which is chosen by an address indicated in the variable part, the second address indicating the first instruction of the selected sequence, the last instruction of each sequence indicating the first register whereby to select the instruction stored at the address indicated by the contents of the first register to allow modification of the content of the second register to allow different instruction sequences to be selected. An instruction TAL, R x , D (Fig. 1) stored at address n has an operator portion TAL and two variable portions R x , D stored in instruction memory IM (Fig. 2). Assuming that this data is read out via results register IR and fed to decoder AVK a shift register in a control unit SE produces consecutive timing pulses 1-13 connected to gates G1-G15 where indicated. Clock pulse 1 causes address n from the address register IA to pass to an operand register DB of an arithmetic unit AR. Pulse 2 passes the content of PRA (installed in a previous operation) which is the number to be added to n to produce the address of the first instruction of a desired subprogramme to a second operand address register DA of the arithmetic unit. Pulse 3 causes addition and pulse 4 reads out the sum from the result register AD to a programme output register P # R and then at pulse 5 to the address register IA. Thus the address n + 1 in Fig. 1 has been produced and pulses 6 and 7 cause readout of address P, contained in address n + 1, to programme input register PIR and to the programme output register P # R. Pulse 8 causes readout of variable D from the decoder to register DA and pulse 9 causes subtraction of this number from register DB which still contains address n and produces address n-D read out from register AD and to register LRA during pulses 10. Thereafter the pulses 11, 12, 13 enter address P in IA and cause readout of the first instruction of the subroutine and entry of it in decoder AVK. At the end of the sub-routine an instruction causes transfer of the contents of LRA i.e. n-D to P # R and thence to memory to cause an updating routine to commence whereby, for instance, R x  may be updated to R x  + 1 and cause the sub-routine at address g to be accessed.
