Abstract: 1,134,065. Electronic counters. STANDARD TELEPHONES & CABLES Ltd. 28 Feb., 1966 [3 March, 1965], No. 8599/66. Heading G4A. Gating devices ensure correct operation of a ring counter so that only one of stages B1- B2n is in state 1 at any time. Initially B1 is set to 1 by a pulse at M. All other stages are at 0 so that AND gate a maintains B1 at 1. A circuit A directs alternate pulses to leads I and P. The first restores B1 to 0 and through capacitor C1 sets B2 to 1. The next pulse, on lead P, transfers condition 1 to B3, and so on. While B1 is at 1 it maintains all odd-numbered stages at 0 through gates such as d3 and d2n-1. The pulses on I and P are restoring pulses except in the condition described.

Filed: 1975-03-03
Abstract: 1495408 Determining TDC in IC engines SCANS ASSOCIATES Inc 3 March 1975 [18 April 1974] 8758/75 Heading G1N The top dead centre (TDC) position of a selected piston in a multi-cylinder I.C. engine is established by determining the corresponding mid-crank position of an adjacent piston for a V-8 type engine, or the corresponding two-thirds crank position for a six-cylinder engine. As shown for a V-8 engine (Fig. 5), a frame member 33 is placed on the engine block 52 so that two differential transformer displacement transducers 31 are located over the number 3 and number 5 pistons. The core 34 (Fig. 8) of each transducer 31 is in contact with a probe 36 carrying three radial feet 44 which are spring biased to touch the surface of the associated piston 64. The signals from the two transducers 31 are fed to a differential amplifier, and the crankshaft rotated until the signals are equal, corresponding to the numbers 3 and 5 pistons being in midcrank position and the number 1 piston at TDC. The engine casing is marked accordingly. The  frame member 33 is attached to a pump 54 which applies a vacuum to the numbers 3, 5 cylinders to keep their pistons vertical and eliminate slack. In the preferred embodiment, the TDC position of number 1 piston is determined by calculating the downward displacement S from TDC of another piston corresponding to TDC for the first piston. The calculation involves the value of the crank throw r, and the value of 2r is determined by measuring the maximum difference in displacement S during a complete revolution of the crank-shaft, using the differential transformer 31. A computer determines the required value of S for this piston, based on the measured value of r, the known value of the length of the connecting rod and the crankshaft angle to position number 1 piston at TDC.

Title: Method of and apparatus for assembling helical members, to form half lays and the like
IPC: H02G1/02
Filed: 1964-03-03
Abstract: 1,016,275. Assembling pre-formed helical elements. PREFORMED LINE PRODUCTS CO. March 3, 1964 [March 8, 1963], No. 8898/64. Heading D1T. The invention relates to a method and means of assembling preformed helical rods together so as to form half-lays and the like therefrom. According to the method a first helical rod is placed in a longitudinally fixed position, one end of a second helical rod is aligned in an off-set manner with one end of the first rod, and the second rod is then moved axially to bring it into engagement with the first rod in a manner threading said second rod with said first rod. The helical rods 11 Fig. 4 are stored in an inclined magazine 22 and are fed one at a time, by notched discs 120, to an endless belt 18C. As each helical rod drops on to the belt 120 it is fed axially between adjustably spaced guide strips 230, 231 and is caused to rotate by a rotation initiator 40 secured to guide strip 231. As the helical rod moves axially it passes under a further rotation initiator 257, Fig. 10 (not shown) and finally passes through a rod end positioning unit 260 Fig. 9 (not shown) that positions the leading end 13 of each rod in a predetermined position before passing the rod into a receiving unit 23 Figs. 3 and 11 (not shown) the unit 260 rotating the rod as the rod passes through it. If the helical rod 11 is the first rod of a subset 10, Fig. 1, the receiving unit indexer the helical rod 11 radially about its axis so that the leading end 13 of the next helical rod 11 to be fed into the receiving unit 23 by the positioning unit 260 does not come into interference engagement with the trailing end 14 of the helical rod 11 already received. As each successive helical rod 11 is introduced, the receiving unit 23 indexer the partial subset 12, Fig. 2, in the foregoing manner. The positioning unit 260 introducer each helical rod axially into the receiving unit 23 whilst also rotating the helical rod 11 about its axis whereby the helical rod is threaded into the partial sub-set 12 already assembled and seated in the receiving unit 23. When an appropriate number of wires have been threaded together to form a sub-set 10 the internal surfaces of the wire may be coated with an adhesive and held in contiguous relationship until the adhesive hardens. The method includes the step of rotating each successive helical rod 11 by a predetermined amount as it is threaded into a sub-set 12 whereby the trailing end of each of said successive helical rods is displaced from the radial portion at which their leading ends were introduced to said receiving means.
