Title: Drawing Instrument
IPC: B43L13/02
Filed: 1979-07-21
Abstract: A multiple use drawing instrument is made of a piece of transparent plastic or other suitable transparent material either oblong or of any other appropriate shape and of a thickness which permits lines of holes to be pierced and where necessary countersunk at appropriate places in it. Distances are marked off on paper immediately below the instrument by penetrating a pencil or pen through one hole and again through another vertically above it. Fixed distances already marked are measured by observing initial and final points appearing within two holes one vertically above the other. All other sizes of circles are circumscribed by penetrating a pencil or a fine pin in one hole and a second pencil in another hole revolving the pencil forming the radius and thus the instrument around the pencil or pin to circumscribe any circle desired. Parallel lines are drawn by penetrating any chosen hole with a pencil or pen and at the same time sliding the lower edge of the instrument along a ruler or tee-square held firmly and so drawing a horizontal line. The action is repeated using other holes to draw other lines parallel to the first. <IMAGE>
Patent GB-2057052-A (GB)
Title: Internal Combustion Engine Cycles
IPC: F02F1/24
Filed: 1979-08-10
Abstract: In an internal combustion engine a charge chamber communicates with the combustion chamber via a valve which opens and closes at predetermined stages in the engine operating cycle. Between the conventional intake and compression stages of the cycle, there is an additional compression stage in which a portion of the fuel mixture in the combustion chamber is forced into the charge chamber and an additional intake stage in which the contents of the charge chamber are released into the combustion chamber while further fuel mixture enters the combustion chamber through the inlet valve or port. The normal compression, combustion and exhaust stages then take place, the compression ratio having been increased by the presence of the additional fuel mixture from the charge chamber. <IMAGE>

Patent GB-2044925-A (GB)
Title: Detecting defects in patterns
IPC: G01N21/956
Filed: 1980-03-14
Abstract: A system for detecting defects in repeating patterns, wherein the elements (62) of the patterns may have variations in spatial period, includes means for scanning and detecting the elements of a pattern to produce an output signal indicative of the pattern and means (80) for autocorrelating the output signal. In an analog version, means (82) delay the output signal from the scanning and detecting means by a constant amount to produce a delayed output signal. Next, any deviation in period between the undelayed output signal and the delayed output signal is detected by suitable means (82, A ,B, C). Means (C1, C2, D, E) then adjust the scanning rate so as to match the periods of the undelayed and delayed output signals, and a subtractor may then correlate the matched original and delayed output signals. In a digital version (Figure 11 not shown), the scanning rate is held constant, the delay time being varied so as to match the periods of the delayed and undelayed signals. <IMAGE>

Title: A Motor Vehicle Hydraulic Braking System
IPC: B60T8/58
Filed: 1980-03-19
Abstract: The invention relates to valves for modulating the hydraulic pressure of a vehicle braking system in response to a change in load on the vehicle. The valve is controlled by two vibration frequency sensors 21 and 22, which are attached to sprung and unsprung portions of the vehicle respectively. The frequency signals from the two sensors are analysed and compared to produce a resultant signal when the two respective vibrational amplitudes of the signals are equal. The natural frequency at which said amplitudes are equal is related to the load on the vehicle and the value of the natural frequency can be utilised for controlling the modulating valve. <IMAGE>
