Patent GB-2041871-A (GB)
Title: Suspensions of Drug- containing Liposomes
IPC: A61K9/50
Filed: 1980-01-17
Abstract: Pharmaceutical suspensions of liposomes containing a drug (e.g. doxorubicin hydrochloride, aminosidine sulphate or 5- fluorouracil) are prepared by dissolution of lipidic components in a solvent, addition of an aqueous solution of the drug, and emulsification by insufflation of an inert gas until the solvent is completely removed by evaporation, and then the liposomes are separated from non-entrapped drug by shaking the suspension with a polymeric ion exchange resin or a polymeric absorbent resin to absorb the non- entrapped drug, then filtering off the resin. The ion exchange resin may be a strong or weak, anionic or cationic resin. The resultant liposomic suspensions may be lyophilised.

Title: Method of control of NC machine tools
IPC: G05B19/416
Filed: 1980-09-25
Abstract: In an NC machine tool, all control data necessary for preparing machining data is inputted into a control device by key switches provided on an operating board. The data necessary for machining a workpiece stored in a microcomputer contained in the NC machine is reduced to the lowest minimum, while various data, such as the paths of movement of tools during rough machining, rough finish machining and finish machining, actually needed for machining the workpiece are successively computed on the basis of the data stored in said microcomputer in advance. Thus, data associated with a variety of workpieces can be processed with a minimum of memory capacity, and complicated shapes having concaves and convexes can accurately be machined in a simple operation. <IMAGE>

Title: Optical Waveguide and Methods of Propagating Waves Therein
IPC: H04B10/2581
Filed: 1980-09-26
Abstract: Conventional optical waveguides are of very small diameter making handling and coupling difficult. Also the HE11 mode is used and this can give rise to contamination where inhomogeneities arise in the waveguide. The waveguide of the present invention has a tube 10 of higher permittivity optical material, with a core 11 of lower permittivity optical material and cladding 12 again of lower permittivity material. The critical dimension is the thickness of the tube 10 and the tube diameter can therefore be made very much larger than that of the conventional optical waveguide. Such a waveguide when properly excited will support the HE11 wave as a single mode or alternatively the TE01 or TM01 mode as a pure wave. Methods of launching and propagating these modes are described. As shown light from a laser 16 is split, a 180 DEG  phase difference is introduced by beam portion 19, and the two portions are introduced at points 15, 15'. In Fig. 4 (not shown), the two portions are fed in by fibres (22, 23) - one of which is strained to provide the phase difference. <IMAGE>
Patent GB-2089038-A (GB)
Title: Vortex flowmeter
IPC: G01P5/01
Filed: 1980-12-09
Abstract: To measure fluid flow in a pipe 1, a bluff body 2 is located in the pipe so that the fluid flow causes vortices to be generated alternately from the top and bottom edges of the bluff body. The rate at which these vortices are generated is dependent on the rate of flow, and they also cause the refractive index of the fluid to vary. A light source 3 is placed in the pipe with its light output directed at a detector 6. Thus the current of light which reaches the detector is dependent on the rate of fluid flow. <IMAGE>

Patent GB-2079672-A (GB)
Title: Logging machine
IPC: B23Q11/08
Filed: 1981-06-30
Abstract: The timber 4 to be cut into logs is inserted into the machine in the direction of the arrow 6 until it actuates a lever 15 which opens a hydraulic tap 16. This releases oil from a hydraulic piston and cylinder 9 to bring a rotary member 5 into contact with the outer surface of the timber 4. At the same time oil is supplied to a hydraulic motor 7 to rotate the rotary member and feed the timber 4 into a cutting zone 13. When a control plate 17 is actuated by the timber 4, a control valve 19 causes oil to be released from a hydraulic piston and cylinder 14, and a cutter 10 is pivoted transversely to the timber 4 to cut completely through the timber 4. When the cut log falls away, the control plate 17 returns to its original position and the cutter 10 is retracted. Additional safety is provided by a guard 21 which is arranged to be actuated to stop the machine in the event of the operator approaching within a certain distance of the cutting zone 13. <IMAGE>

Title: Clutch disc for a friction clutch
Inventor: LUTZ DIETER
IPC: F16F15/123
Filed: 1983-07-07
Abstract: A hub (1) has a radial flange (5) on which driven plate (7) with clutch friction linings (13) is mounted for rotation through a limited angle. Side plates (15, 17) are connected fast in rotation with one another and are rotatable through a limited angle in relation to the flange (5) and plate (7). Main torsion damping springs (33) act between the driven plate (7) and the side plates (15, 17), and second torsion damping springs (31) act between the side plates and flange (5). A pressure plate (35, 37), which is initially stressed by at least one spring (39, 41, 47, 49) supported on the side plates (15, 17) is fast in rotation but displaceable axially at least between one of the two side plates (15, 17) and the flange (5) or the driven plate (7). The pressure plate (35, 37) is in frictional contact both with the flange (5) and with the driven plate (7) through friction plates (53, 55). Instead of through a separate pressure plate, one of the side plates can also be in direct frictional contact with the axially adjacent friction plate. The friction plates (53, 55) are connected preferably integrally with bearing rings (61, 63) which mount the driven plate (7) on the hub flange (5). <IMAGE>

Title: Deceleration sensitive brake control valve
Inventor: BERISCH VOLKER
IPC: B60T8/28
Filed: 1983-08-12
Abstract: The valve features a stepped piston (3), displaceable in a bore (2) of a housing against a spring force and having a through bore (15), and a valve closure member in the form of a ball (26) co-operating with the stepped piston. Upon braking, ball (26) movable by inertia will determine the opening condition of the valve. The associated valve seat (16) is formed at the piston front face (5) facing the ball (26) and exposed to the inlet pressure (P1). Between the front face (5) and the ball (26), an abutment flange (18) having radial slots is arranged which is displaceable by the piston (3) to a greater extent than the latter and which leaves open a fluid pressure. This occurs under high inlet pressure/low deceleration conditions symptomatic of braking a heavily- loaded vehicle and the piston displaces the abutment flange before the ball can engage the valve seat (16). Full inlet pressure is thereby transmitted to the brake actuators. <IMAGE>
