Patent GB-2113521-A (GB)
Title: Protected feedstuffs and their production
Inventor: LAWES RICHARD WOODFORD
IPC: A23K1/00
Filed: 1982-01-25
Abstract: Feedstuffs comprise a nutritional material such as a high protein dietary supplement, carbohydrate, mineral or vitamin, protected by a coating of an edible water insoluble fatty acid salt. Such feedstuffs are capable of resisting the action of bacteria in the rumen of ruminant animals. This water insoluble salt may be formed in situ by reaction of a water-soluble fatty acid salt with a compound capable of forming a precipitate therewith, e.g. a calcium salt. Alternatively, the fatty acid salt may be formed by direct reaction of reaction of the fatty acid with e.g. calcium oxide, and the nutritional material may also be dispersed in the fatty acid salt while the latter is in the molten state.

Title: Load-responsive pressure- reduction in pneumatic brake systems
IPC: B60T8/18
Filed: 1982-03-04
Abstract: A pneumatic tractor relay valve (as shown) or proportioning valve (fig 10, not shown) or a trailer relay valve (fig 12, not shown) includes a pressure proportioning device which comprises a plurality of concentric bushings (17) telescopically mounted in a chamber between a diaphragm control piston (15), and a coaxial reaction piston (19), pressure transmitted by means of said device depending on the number of said bushings, from the innermost outwards, which are engaging both the diaphragm and the reaction piston. The number of the bushings engaging both said diaphragm and said reaction piston varies inversely with the length of the stroke which said reaction piston has to travel to close the exhaust valve (36, 37) of reaction chamber (28), the exhaust valve having a seat (37) which is axially displaceable as the load acting upon the vehicle varies, moving towards the reaction piston, thereby to decrease said stroke length, as the load increases and away from said reaction piston, thereby to increase said stroke length as the load decreases, whereby the pressure transmitted through the bushings from the control or drive piston to the reaction piston increases as the load on the vehicle increases, and decreases as said load decreases. <IMAGE>

Patent GB-2113497-A (GB)
Title: Waveform shaping circuit
Inventor: MAKITA HIROMITSU
IPC: F02P17/04
Filed: 1982-12-20
Abstract: A waveform shaping circuit includes a low pass filter (2) for eliminating high amplitude, high frequency noise components from a periodic signal, a reference voltage generator (4) for generating a reference voltage which varies in magnitude in dependence upon the average level of the filtered signal and a comparator (3) for comparing the filtered signal with the reference voltage and slicing the filtered signal to remove low frequency, low amplitude noise components from the filtered signal. The circuit is particularly useful in electronic internal combustion engine analyses which analyse the periodic pulse signal produced by the ignition circuit. Such signals are subject to noise due to contact set chatter. The level of this noise is reduced by the above described circuit. The reference voltage generator (4) includes voltage clamping means (14, 15) to reduce the noise sensitivity of the comparator. <IMAGE>

Title: A single-row or double-row rolling bearing
Inventor: HOFMAN HEINRICH
IPC: F16C19/38
Filed: 1982-12-20
Abstract: A single-row or double-row rolling bearing comprises a rimless inner race 8, a rimless outer race 7 and rollers 9. In order to ensure a high radial and axial load capacity of the bearing, to facilitate mass-production of the rollers and to reduce friction resulting from a sliding instead of the desired rolling motion of the rollers, at least the regions adjacent the two end faces 6 of each roller are curved along their longitudinal extent. Alternatively, each roller may be curved convexly with the same radius along its entire length. Whatever roller is used, the, or each, centre 11 of the, or each, curvature is disposed on the opposite side of the bearing axis 10 and the smallest radius 12 of the, or each, curvature is greater than ten times the length of the roller. The shape of the tracks of the inner and outer races is substantially the same as that of the rollers. <IMAGE>
