Patent GB-1501621-A (GB)
Title: Spark ignition systems for internal combustion engines
IPC: F02P3/01
Filed: 1975-02-06
Abstract: 1501621 Ignition systems LUCAS INDUSTRIES Ltd 6 Feb 1975 [8 Feb 1974] 05822/74 Heading F1B A spark ignition system for an internal combustion engine comprises in combination engine driven means for initiating each spark and control means sensitive to one or more engine parameters for prolonging each spark under certain engine conditions. As shown when the contact breaker 32 first opens the spark is initiated by the ignition transformer 15. At the same time the generator 36 starts to operate and turns on the transistor 25 so that energy is stored in the winding 14 at a time well before the normal spark terminates the generator 36 turns the transistor 25 off and the transistor 24 on. The ignition transformer 16 now supplies energy to the plug while full energy is stored in the winding 13 again. Well before all the energy stored in the winding 14 has been dissipated the transistor 24 turns off and the transistor 25 turns on, so that the ignition transformer 15 produces the spark while the ignition transformer 16 restores the full energy level in its primary winding. Thus the spark will be prolonged and will continue to be produced at the plug until the contact breaker 32 closes again unless during the period when the contact breaker 32 is open the central device 37 provides an input to the generator 36 to terminate operation of the generator 36. The device 37 can be a simple logic arrangement receiving inputs from various transducers. In a modification there is a single ignition transformer and two energy storage inductors. During cranking it may be desirable to shortcircuit part or all of the resistor 35 and part of the resistor 31. Although a contact breaker 32 is shown the timing can be purely electronic with a signal from the computor 37 triggering the operation of the signal generator 36. In another modification a capacitor discharges into the primary winding of the ignition transformer to initiate the spark and is then connected in a resonant circuit including the primary winding to prolong the spark under certain engine conditions.

Filed: 1949-03-03
Abstract: 674,170. Reversing gearing; clutches. LANGDON, A. G. April 11, 1950 [March 3, 1949; March 3, 1949], Nos. 5860/49 and 5862/49. Class 80 (ii). A combined clutch, reverse and reduction gearing comprises a driving shaft 2 with a pinion 4 engaging a reduction gear wheel 5 freely mounted upon a driven shaft 7. Friction plates 19, 21 are arranged between a housing 6 attached to the gear 5 and a bush 20 secured to the driven shaft 7 so that when this clutch is engaged the gear 5 drives the shaft 7 directly. The gear 5 has also secured. to it a bevel gear 10 of an epicyclic train which co-operates with planet gears 17 on a carrier 13, which planets also engage a second bevel gear 18 secured to shaft 7. When the clutch 19, 21 is engaged this bevel train rotates solid with the shaft 7 but if the clutch is disengaged and the carrier 13 held by a brake band 29 a reverse drive is imparted through the bevel gears to the shaft 7. The clutch and brake are adapted to be operated alternatively by a single lever 26 with a neutral position in which no drive at all is transmitted. The clutch 19, 21 is actuated through pins 23 in an adjustable end wall 22 of the housing 6 by cams 24 and a sliding sleeve 25, and balls 28 operate in 'inclines between a ring 27 and the pressure plate to increase the clutch pressure and prevent slip. A modified arrangement utilises a spur gear epicyclic train instead of the bevel train and has interconnected planet pinions co-operating with two sun gears.

A machine for finishing the top and bottom of woven mesh lengths for mattresses &c. comprises a pair of fingers which engage adjacent ends of the woven mesh wires and bend them back into engagement with adjacent convolutions, and means for traversing the fingers intermittently across the mesh to engage a fresh pair of ends at each movement. The woven mesh is positioned on a table by a row of pins 3 and is clamped by a hand-actuated bar 8. A carriage, intermittently movable on guides 6, 6a, by a hand wheel 7, carries a slide 12 with fingers 10, 11 for bending the wire ends, blades 49 for shearing the wires and an abutment mandrel 44. The hand wheel 7 rotates a shaft 26 geared to a shaft 23 carrying an eccentric 42 actuating a ratchet mechanism 37 with pinion 35 engaging a fixed rack 34 to traverse the carriage intermittently. A cam 22 on the shaft 23 oscillates the slide 12 carrying the bending fingers 10, 11 pivoted on pins 13, 14 and with projections 15, 16 engaging a fixed camplate 19 to swing the bending fingers. A cam on the shaft 23 actuates the pivoted cutters 49, Fig. 11, not shown. The slide 12 carries a cam-plate 48 for projecting the abutment mandrel 44 to assist the bending. In operation, the length of woven mesh is roughly cut to length and positioned by the pins 3 and clamped by the bar 8. Rotation of the hand wheel 7 actuates the cutter 49 to shear two adjacent wires to length and projects the mandrel 44 behind the crossing of adjacent wires. The slide 12 carrying the fingers 10, 11 is advanced towards the wires and the fingers are swung by the cam-plate 19 to bend the wire ends back into engagement with adjacent convolutions. The carriage is then moved to the next pair of wires and the operation repeated. The ratchet mechanism is reversible to allow the carriage to move in both directions.

In an ejection seat for aircraft provided with a face protection screen for the airman, means such as flexible cords are provided to restrain the arms of the airman from excessive outward movement during ejection from the aircraft. As shown in Fig. 2, which shows the seat during the initial stage of ejection, the face screen 2 carries a looped handle 6 to the ends of the upper bar of which are secured flexible arm-restraining lines 7, 8 which pass through snubbing boxes 9, attached releasably to the sides 3 of the seat 1, to attachments 11 on the cockpit floor 10. Each line may have a frangible portion 13 or the pin 14 securing each line to its attachment 11 may be frangible or the connection to the floor may be spring loaded to disconnect at a predetermined tension. Each snubbing-box 9, which permits a line to pass through downwardly, but not upwardly, is releasably secured to the seat frame by a spring loaded plunger 26 which is moved axially to release the box by a sear 29 attached to one end of a rod 30 which is moved axially in direction of arrow A, Fig. 4, by a further sear 32 moved in direction B at right angles to A by a rod 35 connected to one arm of a bellcrank 37, the other arm 40 of which is attached through a rod 41, arm 42, shaft 43, arm 44, rod 45 and lever 48 to the plunger 49 of a spring box or a gun 50 which is released or fired automatically in association with the apparatus used to free the airman's harness from the seat. In operation, movement of the face blind 2 to the position shown automatically fires the seat ejection gun which causes the seat to rise from the floor 10 and tension lines 7, 8 in positions where they restrain the airman's arms from outward movement, boxes 9 maintaining such tension in the upper portions of the lines. When a predetermined tension has been reached portions 13 or pins 14 fracture to free the airman and seat completely from the aircraft and, as described, subsequent operation of the harness release mechanism frees the airman from lines 7 and 8 and thereby the face screen 6, to enable him to become separated from the seat. The lines 7 and 8 and boxes 9 may be combined with similar lines and boxes for restraining the airman's legs of the type described in Specification 724,955. Specifications 583,257, 640,520, 652,131, 673,147, 711,234 and 761,507 also are referred to.

Title: Error detection in computers
IPC: G06F11/10
Filed: 1978-02-16
Abstract: A memory system includes a cache store and a backing store.  The cache store provides fast access to blocks of information previously fetched from the backing store in response to commands.  The backing store includes error detection and correction apparatus for detecting and correcting errors in the information read from backing store during a backing store cycle of operation.  The cache store includes parity generation circuits which generate check bits for the addresses to be written into a director associated therewith.  Additionally, the cache store includes parity check circuits for detecting errors in the addresses and information read from the cache store during a read cycle of operation.  The memory system further includes control apparatus for enabling for operation, the backing store and cache store in response to the commands.  The control apparatus includes circuits which couples to the parity check circuits.  Such circuits are operative upon detecting an error in either an address or information read from the cache store to simulate a condition that the information requested was not stored in cache store.  This causes the control apparatus to initiate a backing store cycle of operation for read out of a correct version of the requested information thereby eliminating the necessity of including in cache store more complex detection and correction circuits.
