Patent GB-2087477-A (GB)
Title: Ignition Systems for Internal Combustion Engines
IPC: F02P3/045
Filed: 1980-10-07
Abstract: The ignition system employs a single-chip micro-computer 1 to determine the required ignition advance for the prevailing engine speed and to control ignition coil switch-on and switch-off to provide sparks at the appropriate times. The task of determining ignition advance is simplified by dividing the engine speed range into bands, using simple approximations to calculate ignition advance for bands in the low- speed range, and employing a look-up table to determine ignition advance for bands in the high-speed range, The simplified approximations are arrived at by fitting, to the ignition advance/speed characteristic for an engine, a series of straight lines. The system includes a Hall effect sensor 4, the output of which is connected to the computer to determine the engine speed. The computer also receives inputs from an inlet manifold pressure sensor and a knock sensor, the computer retarding the ignition if knocking is detected. <IMAGE>

Title: A Tongue and Buckle Fastener for a Safety Belt
IPC: A44B11/25
Filed: 1981-09-14
Abstract: False latching of tongue 10 in buckle 12 is prevented by use of an auxiliary member 70 to stop bolt 48 sliding to its engaging position until the tongue 10 is inserted sufficiently far to offer no hindrance to its motion. Ends 90,92 of member 70, which are wider than tongue 10 is thick, engage under latching shoulders 58,60 of bolt 48 until the tongue causes them to move by means of pressure against portions 86,88 which bows parts 78,80 of member 70. At this point, latching parts 16,18 of tongue 10 have passed the line of movement of the now-freed bolt 48 which moves under the action of spring 66 to engage them. Push-button 22 releases the fastening by lifting bolt 48, whereupon ejector 36 expels the tongue 10 from passage 30. This ejector is thicker than member 70 is wide, but meets the tongue with a tapering portion 47. <IMAGE>

Title: Tone generator for electronic musical instrument
Inventor: KASHIO TOSHIO
IPC: G10H7/12
Filed: 1979-03-14
Abstract: A time multiplexed logic system for constructing up to eight notes simultaneously. Essentially the waveform of each is a set of 16 waveform blocks, each having a duration between 8 and 16 clock periods and an amplitude which is a product of an attack/decay envelope value (Figs. 7C2, 7D2) and a basic waveform amplitude which is stored at 35 (Figs. 7B1, 7A1) as a set of 16 difference values (Fig. 3). The amplitude product values for each waveform are generated during respective ones of 8 consecutive time channels and applied sequentially to an adder 52 (Figs. 7C1, 12), i.e. samples of a particular waveform appear every 8 clock periods Simultaneously with each sample of each note a time value code Y1-Y2- Y4 is derived (Figs. 7B2, 7A2) from keyboard circuitry and this determines into which line of a shift register assembly 49 it is added. The register is shifted upwards at the clock frequency so each sample may be delayed by up to eight clock periods. Thus samples for any particular note appear at the shift register output at intervals between 8 and 16 clock periods; the number varies from block to block and the total for the sixteen blocks of a note determines its frequency. <IMAGE>

Title: A method of and an arrangement for determining injected quantities of fuel
Inventor: SCHMITZ ECKEHART
IPC: G01F3/04
Filed: 1982-07-16
Abstract: In a method and an arrangement for determining the quantity of fuel injected by means of a camshaft- driven piston injection pump for automatic-ignition internal combustion engines, the pressure pulses occurring in the output pressure line of the injection pump during the injection-effective delivery stroke are directly or indirectly determined in respect of their pulse duration and their pulse intervals. A certain injection stroke or a certain quantity of fuel injected per work cycle may be associated in pump-specific form with each pair of these values and stored and retrieved as required. This cycle-related injected quantity may be used for determining the consumption of fuel per unit time or per unit distance travelled and optionally averaged out as a function of time or even the overall consumption, optionally with the assistance of other values, such as the rotational speed as derived from the pulse intervals or a speed signal.
