Patent GB-2117061-A (GB)
Title: A liquid fuel distributor
Inventor: WOODWARD HENRY EDWIN
IPC: F02M59/46
Filed: 1983-03-01
Abstract: The distributor is for use in a fuel injection system and comprises a rotor (56), a fuel inlet (50) for feeding fuel under pressure from a servo pump (10, 12, 14) to the rotor and a plurality of fuel outlets (61) for supplying fuel under pressure to a plurality of fuel injectors in turn, the injectors comprising fuel actuated pumping pistons. Each outlet has an outlet valve (53) operable by fuel pressure at the rotor and each outlet valve has a pressure operated return valve (67) to allow return fuel flow when fuel injection terminates if pressure in the outlet exceeds pressure in the inlet e.g. due to dynamic effects. The rotor has metering means in the form of a plurality of metering ports (79) which align with the fuel outlets (61) when, during return strokes of the pumping pistons fuel from the injectors. The rate of flow through the metering ports (79) determines the return stroke of each injection piston and thus the quantity delivered during that piston's next delivery stroke. Means (72, 75, 76, 77) are provided for controlling the axial position of the rotor as a function of engine speed for controlling the injection timing. The degree of registration between the ports (61, 79) and the position of an edge 82 on an axially adjustable member 83 control the rate of flow. <IMAGE>

Title: Locating moving radio sources
Inventor: CUSDIN ANTHONY RICHARD
IPC: G01S5/04
Filed: 1983-03-07
Abstract: Signals from moving sources are received at two spaced locations A, B, by respective monopulse antennae 1 each having sum and difference radiation patterns. In order to confirm that the signals received at A and B are from the same source, the two signals are correlated; signals from a single source produce a strong correlation peak, whilst those from different sources cancel out over time. The signals are a also frequency analysed. The bearings of a source can be determined by scanning both the antennae to obtain minima in the associated components of the spectra derived from the difference patterns when the source is located in the central nulls thereof. The position with respect to each location may alternatively be determined by combining scanning with determining the phase difference between the signals received by the two antennae, the phase difference being between appropriate spectral components derived from the frequency analysis. The velocity of a source can be found by receiving signals at a third spaced location (C, Fig 8) and determining the two respective differences between the Doppler shifts of the signals received at two pairs of the three locations A, B, (C). <IMAGE>

Title: Positive clutch differential
Inventor: SCHOU CARL E
IPC: F16H48/12
Filed: 1983-03-22
Abstract: A differential assembly of the automotive vehicle type, for rotating axially aligned drive axles, has a rotatable driving casing 10 which distributes the power to the inner end portions of the axles, A center ring member 13, having opposite wedge-like, face tooth formations, is secured within the casing for meshing with and driving corresponding tooth formations on a pair of pressure rings 32 between which the center ring member is positioned. Each pressure ring is connected to one of the axles through a friction clutch 39, 40. The pressure rings are movable towards and away from the center ring for respectively disengaging and engaging their clutches. A splined stop ring 35 meshes with corresponding internal splines formed on each of the pressure rings for limiting each pressure ring's rotational movement relative to the center ring for holding the meshed center ring teeth and the teeth of either pressure ring apart when that pressure ring's rotational speed exceeds the rotational speed of the center ring and casing. During such speed conditions, the respective pressure ring can move towards the center ring so as to disengage its clutch and permit its axle to free wheel while the opposite axle is still driven by the rotating casing. <IMAGE>

Abstract: A machine for packaging articles in continuous tubular material, which may be formed by rolling the marginal edges of a flat web around a succession of the product articles to bring the marginal edges into contact and then sealing them continuously to complete the tube, comprises a pair of transverse sealing jaws 14 and 1 which each include a hemi-cylindrical chamber 24 having gas-pervious walls 16 and defining a cylindrical space 25 initially centrally divided by the film between two successive product articles 1.The film extending diametrically across the space 25 is first of all severed and then suction is applied to the gas-pervious walls 16 to draw the film into contact with the walls 16. To the righthand side of the space 25 is a double impulse sealing system 18, 19 centrally divided by a knife 21 which separates a righthand pack 28 from the film in the space 25, and to the lefthand side of that space 25 is a further double impulse sealing system 18, 20, again with a knife 22 to effect separation. The sealing pads 20 at the lefthand side are movable by means of push rods 27 so that initially they allow the pack 8bto be communicated with the space 25 while the pack 8a has been separated from the space 25, and this enables gas from within the pack 8b to be extracted by way of the hemi-cylindrical chambers 24 and the suction conduits 17. Subsequently the two sealing pads 20 are pressed into contact with their counterpressure pads 18 and the righthand side of the pack 8b is then isolated from the space 25.

Title: Liquid 2-hydroxy-methylthiobutyric acid and process for the preparation thereof
Inventor: RUEST DENNIS ARTHUR
IPC: A23K50/15
Filed: 1984-11-13
Abstract: A process for the preparation of 2-hydroxy-4-methylthiobutyric acid having improved color, odor and lower viscosity. 2-hydroxy-4-methylthiobutyronitrile is hydrolyzed with sulfuric acid having an initial strength of between about 50% by weight and about 70% by weight on an organic-free basis, thereby producing an intermediate aqueous hydrolysis product solution containing 2-hydroxy-4-methylthiobutyramide. The 2-hydroxy-4-methylthiobuty- ramide is hydrolyzed with sulfuric acid having a strength of between about 30% by weight and about 50% by weight on an organic-free basis to produce an aqueous hydrolyzate containing 2-hydroxy-4-methylthiobutyric acid. The hydrolyzate solution is contacted with a substantially water-immiscible organic solvent in a liquid-liquid extraction system to produce an extract comprising the solvent and 2-hydroxy-4-methylthiobutyric acid transferred from the hydrolyzate. The acid product is then recovered from the extract.
