Title: Yaw angle and life/drag ratio optimising hydrofoil keel
Inventor: SIMS MERRICK LEVISON
IPC: B63B3/38
Filed: 1986-01-24
Abstract: The lifting surface area of a hydrofoil keel operating on a sailing vessel is determined so that when the keel is travelling through the water at the beating hull speed of the boat, it generates just sufficient lift at that angle of attack which gives the keel's highest lift/drag ratio to balance the side force generated by the vessel's sails throughout a given apparent wind speed range. The moment coefficient of the boat-sail combination is also adjusted so that when the above relationship is in force, the boat will be in rotational equilibrium at the keel angle of attack giving the keel's highest lift/drag ratio, so that rudder drag will also be minimised at this point. A means is also provided for varying the lifting surface area of the keel to allow it to maintain the equilibrium for wind speeds outside the abovementioned range.

Title: Method and apparatus for forming curled rims on cups
Inventor: THOMPSON ALAN
IPC: B29C51/30
Filed: 1986-02-05
Abstract: A throw-away drinking cup vacuum-formed from sheet material, e.g. polystyrene, is first formed with a more or less curved flange around the mouth which has one or more radially-spaced, circumferentially- extending notches (17) in its inner or outer surface so that when the flange is curled into a rim of approximately circular cross-section, material can flow more easily than if the rings had not been formed and a good curled rim can be formed with little tendency to uncurl. A mould (13) used for forming the cup has, or is in combination with, an annular ring for defining the mouth of the cup which has one or more protrusions (16) which will produce notches or indentations when the cup is formed. <IMAGE>

IPC: C25D9/08
Filed: 1986-09-04
Abstract: A CdTe compound is formed by electrochemical deposition from a bath containing Cd and Te under diffusion controlled conditions with current controlled at substantially constant value. Bath composition, temperature and degree of agitation are controlled such that the initial iR-corrected potential falls in a region where a single phase compound containing Cd and Te is deposited. The process is simpler then prior art processes to operate on a commercial scale and may be used in the fabrication of photovoltaic devices.

Title: Bale density control system for a machine for forming cylindrical bales of crop
Inventor: GEISER JENS
IPC: A01F15/08
Filed: 1986-11-14
Abstract: A machine for forming large cylindrical bales of hay has a baling chamber consisting of a frusto-conical crop receiving portion (18) and a cylindrical crop discharge portion (22). The portions are arranged end-to- end and are defined by rolls which are driven to roll the crop round on itself into the form of a bale. The bale is compacted in the discharge portion by being forced by incoming crop against an abutment plate (52) which is hydraulically controlled. The bale is wrapped with twine from a tying device and severed by a cutter before being released through a gate (30). The whole operation is continuous. In order to produce bales with a desirable density without undue stress to the machine, a control system (58) relieves the hydraulic pressure affording the resistance to bale movement by the abutment plate (52), Sensors (60, 62) detect any drive torque of the machine outside a predetermined range and any lack of advancement of the bale, and their outputs are fed to a computer (64) controlling a relief valve (66) enabling the abutment plate (52) to yield and the growing bale to advance further. <IMAGE>

Title: Extracting device
Inventor: HENRY HUGH RICHARD
IPC: B25B27/06
Filed: 1987-01-07
Abstract: There is disclosed a device for extracting ferrules from rail carrying chairs comprising a ferrule-engaging head 50, a radially extending flange 70 and a rod extending from the flange away from the head. The head 50 includes teeth 52, 55, 58, 61 diminishing in diameter and effective to bite into the ferrule. The diameter and length of the head 50 being such that, after the head 50 has been accommodated inside the ferrule, displacement of the rod transversely of its longitudinal axis causes displacement of he head 50 whereby one side thereof bites into the ferrule with the aid of its teeth and the opposite side of the flange 70 bears as a pivot on the surface of the chair. The ferrule is pulled up and out of the hole of the chair as displacement of the rod continues. The rod is attached to the flange 70 via a stub 80 which is integral with the flange 70 which in turn is integral with the head 50. The flange and stub are made of heat toughened carbon steel. <IMAGE>

Patent GB-2272813-A (GB)
Title: Optical fibre transmission system
Inventor: BYRON KEVIN CHRISTOPHER
IPC: H04B10/85
Filed: 1987-06-20
Abstract: To transmit digital information in a secure manner in an optical fibre, the same information is modulated (M1, M2, M3) via different delays ( tau 1,  tau 2,  tau 3) on to lasers (L1, L2, L3) running at different wavelengths. The delays are so chosen with respect to the group velocity differences in the optical fibre that the pulses are superimposed at the output. However, due to the velocity differences and the relative weakness of the individual components the pulses are scrambled between the input to the fibre and the output therefrom. Then a high degree of security is attained. Tapping is readily detectable because the individual lasers run at powers lower than the detector's sensitivity so if power is tapped out at an intermediate point the loss of power at the output is readily detectable. <IMAGE>

Abstract: An ink ribbon cartridge for an electronic typewriter or printer comprises a case 2 containing the ribbon 8, a ribbon supply spool 6, a ribbon winding spool 4 and a tension member comprising an L-shaped spring 26, whose middle curved portion is supported on the spindle of the supply spool 6. A first leg 26a of the L-shaped spring 26 is adjustably fixed on a corner structure 28 of the case 2, while a second leg 26b thereof holds the ribbon 8 to tension it. A resilient biassing means comprises a torsion spring 12 resiliently pressing the spindle of the winding spool 4 toward the driving gear 16. A guide roll 20 has sides which are tapered bidirectionally from its center line to both ends so that the ribbon 8 may be guided without being folded longitudinally. Entrance and exit guides 34b, 34a are inclined toward one another so that the lower ribbon edge is more tensioned by spring 26. When the printing hammer strikes it plastically strains and loosens the ribbon along its lower edge, but the upper ribbon edge retains its elasticity and helps the ribbon move past the hammer. <IMAGE>
