Title: Methods and apparatus for wiring apertured articles
IPC: G11C11/06
Filed: 1966-04-26
Abstract: 1,123,800. Making magnetic memories. INTERNATIONAL BUSINESS MACHINES CORP. 26 April, 1966 [30 April, 1965], No. 18128/66. Heading B3A. [Also in Division H3] Magnetic cores to be wired are prestrung on a plurality of wires which are then arranged in a support, the leading core on each wire is separated from the remainder, the separated cores are held against a jig so that their apertures are aligned and a wire is threaded through the aligned apertures. The process is repeated for the remaining cores. In Fig. 2, wires 22, on which the cores 20 have been threaded, are supported in a frame 24. All the cores are then moved from right to left along the wires by air pressure from jet 43. When the cores reach a stop surface on jig 36, the leading core on each wire 22 is sucked into a groove 38. These cores are retained in the groove while the remaining cores are blown back to the right-hand end of frame 24 by air from a second jet. The jig is then lowered, moved to the right and raised so that the separated cores are adjacent the shaped left-hand face of the jig. The cores are held against this surface by air from a duct extending across the width of the frame, the air pressure acting somewhat in a downward direction to hold the upper parts of the cores against wires 22. Wire 54f is then passed through the cores by way of horizontal slots in the outwardly extending portions of the shaped surface of the jig. It is stated that, as well as holding the cores against the jig, the air acts as a lubricant assisting threading of the wire. When wire 54f has been threaded, a signal generator may be connected across its ends and correct operation indicated by detectors connected to each wire 22. If a defective core is found it may be removed, wire 54f may be retracted and the process repeated. Alternatively the cores may be tested by threading a probe 80 through them immediately prior to threading by wire 54. When a row has been successfully threaded, the ends of wire 54f are soldered to contact areas 82 and wire is broken off at 94. Before wiring the next row, frame 24 is moved relative to the jig and the wire source 74 to align the wire 54 with the next contact areas 92. The jig is also moved one wire upwards or downwards to produce the " diamond " pattern of cores. A three-wire matrix may be constructed by prestringing the cores on two vertically separated wires, the separation corresponding to the diameter of the third wire, which is passed between the other two. The air jet holding the cores against the jig is in this case directed upwards to reduce turbulence. Alternatively, the cores may be prestrung on a single wire and two wires may be threaded laterally by using two air jets. The cores are first forced upwards while an upper wire is threaded and are then forced downwards during threading of a lower wire.

Title: Improvements in the propulsion of vehicles
IPC: B62D57/00
Filed: 1921-07-06
Abstract: 179,501. Tekniske Forsogsaktieselskab. May 3, 1921, [Convention date]. Machinery, utilizing inertia to obtain movement in. - Vehicles, sledges, tractors, &c. are propelled by means of a succession of impulses obtained from oscillating, rotating, or reciprocating members, the inertia of which is utilized to impart a blow to a part of the vehicle or to propel it as the result of reaction against the road surface. In the construction of sledge shown in side elevation and in plan in Figs. 3 and 4a respectively, two approximately vertical shafts C driven through flexible joints from a motor M carry weights W on arms S. The lower ends of the shafts are connected direct or through springs x', x<2> to a frame C', suspended by links B. The oscillations of the frame when the shafts are rotated are utilized to propel the sledge through springs x, the necessary reaction from the ground being obtained through shoes E connected to the frame C' by links D and springs Z. In a modification, the propulsive effort is transmitted to the vehicle by a succession of blows acting on a resilient buffer. A modified method of obtaining a non- return action of the road engaging means is shown in Fig. 5. The links D are fitted with brake blocks E<1> which engage the rollers R and prevent their rotation during the working stroke, while allowing free movement during the return stroke. Horizontal guides may be used instead of links to guide the reciprocating members. The semiportable apparatus shown in Fig. 7 is moved by a succession of impulses due to the hammer W striking the buffer N. The hammer is oscillated by tappets on a pulley driven from the motor M. The agricultural plough shown in Fig. 8 is driven forward by blows delivered on the spring buffer N by a hammer W which is oscillated by a hollow shaft R carrying an unbalanced weight W<1> and driven from the motor M. The hammer is connected to the casing by a spring x, the backward pressure on which must not be sufficient to overcome the resistance to backward movement of the ploughshare Q. In a modification, two rotary weights driven by bevel-gearing are employed to reciprocate a hammer movable in a straight line.

Abstract: 1,181,459. Semi-conductor devices. NIPPON ELECTRIC CO. Ltd. 20 April, 1967 [30 Sept., 1966]. No. 18293/67. Heading H1K. A semi-conductor device 31, Fig. 5, is mounted on an insulating support 11, Figs. 1b and 5, on which is also deposited at least one (as shown, two) first conductor(s) 13, 14, Fig. 1a, and a second conductor in two parts 15, 15<SP>1</SP> which flank the first conductor(s). The first and second conductors constitute the device terminals; a further conductor 12 serves as an earth contact for the support 11. The device may, as in Fig. 5, be encapsulated by the provision of a cover 51 which may carry a second earthing contact 12<SP>1</SP>. The two conductor parts 15, 15<SP>1</SP> are shorted together and the earthing contact(s) may be shorted to one of the terminal conductors. For a transistor, its collector may be connected to the conductor 14 of Fig. 1a and either its emitter or its base to the conductor 13. The other electrode will then be connected to both of the conductor parts 15 and 151 so that 15-15<SP>1</SP> is a common terminal, 15-15<SP>1</SP> and 13 are the input terminals and 15-15<SP>1</SP> are the output terminals. In the general case, where 15-15<SP>1</SP> is not shorted to 12, the common terminal is "A.C. grounded", i.e. connected to earth by the capacitance constituted by the dielectric of the support 11 sandwiched between the earth contact 12 and the common terminal 15-15<SP>1</SP>. To ensure that this capacitance is large in relation to the capacitance between the earth contact and the signal conductors, i.e. terminals 13 and 14, the thickness or dielectric constant of the material between the earth contact and the common terminal may be made different from that between the earth contact and the signal conductors.

The code lines may be linked by lines parallel to the tracks to produce a character which is humanly legible, as shown in Fig. 4, where each character is in a 4/6 code and has one pair of code lines which are aligned in the two tracks. Fig. 6 (not shown) illustrates a similar arrangement using a 3/6 code. Sensing.-An image of the circular tracks is centred with respect to an optical axis and is rotated with respect to a pair of photo-detectors by an image converter tube and optical system as described in Specification 1,219,251. Circuit, Fig. 5.-Outputs from the two sensing channels 87, 88 are supplied to a clock generator 90 supplying pulses for shifting the sensed data into registers 101, 102 and for advancing a divide by 3 counter 103. When this counter provides an output, gate 121 checks that an output is simultaneously obtained from gate 120 signifying that the character just sensed had an odd number of coinciding code lines (gate 114 and toggle flip-flop) and at least one single code line (gate 116 and bi-stable 117). When the gap 47, Fig. 4, following a character is detected at 111, generator 95 produces a character pulse CP provided gate 121 and hence gate 122 have not produced an invalid character output to set error detector 130 and reset bi-stable 135. The character pulse CP enables a decimal decoder 105 and a Y10 check circuit 123 so that if a valid output is obtained from decoder 105, the output of BCD converter 106 is passed to a recirculating delay line store 108. If error detector is set during the sensing of a label, it opens the recirculating path of store 108 to erase the data stored. When detector 131 detects a long gap at the end of the data, the contents of store 108 are transferred to an output magnetic disc or tape, printer or punching apparatus. The sensing operation is automatically repeated if an error was detected, and a counter 138 may be provided to allow output transfer of data only after a given number of error-free sensing operations have been performed. A similar but simplified circuit is used for codes of the Fig. 6 type.
