Title: Method of culturing crypthecodinium cohnii
Inventor: RATLEDGE COLIN
IPC: C12N1/12
Filed: 2001-02-09
Abstract: A method of culturing Crypthecodinium cohnii (a dinoflagellate marine algae) or microorganisms derived from it in a medium containing propionic acid. The medium may also contain sea salt, yeast extract or a carbon source which may be glucose or acetic acid or acetate. The propanoic acid may be added during the course of culturing to maintain a constant concentration and the acetic acid may be added in response to increase in pH so as to maintain the pH at 6.5. The propionic acid increases the dry cell weight produced by the culture and the amount of the fatty acid docosahexaenoic acid (DHA) produced and causes an increase in the ratio of cyst to swimmer forms of cohnii. A method of culturing C. cohnii in a medium containing a carbon source and an acid and a medium suitable for culturing C.cohnii containing propionic acid and sea salt are also disclosed.

Title: Camshaft assembly with selectively engageable and disengageable cam lobes
Inventor: HURR WILLIAM JOHN
IPC: F01L1/047
Filed: 2001-03-20
Abstract: A camshaft assembly comprising a cam lobe which can be selectively engaged to and disengaged from the cam shaft and means to ensure that there is no relative motion between the cam shaft and the cam lobe during operation of the zero lift portion. This enables engagement and disengagement at any rotational speed of the camshaft assembly. In the illustrated embodiment, a switchable cam lobe 1 having a zero lift portion 16 is provided with a slot 13 within which a flat sided cam shaft segment 2 is located. A compression spring 6 is located in the slot and urges the zero lift portion of the cam lobe into contact with the cam shaft segment. Latching pins 8 are slidably located within passages 15 in the cam shaft segment and, when the zero lift portion of the cam lobe is in contact with the cam shaft segment, return pins 9 are located opposite the latching pins. The return pins we located in passages 14 in the cam lobe and are biased towards the cam shaft segment by return springs 11. Outward movement of the latching pins into the passages 14, against the action of the return pins, engages the cam shaft segment with the cam lobe. Movement of the latching pins is effected by oil pressure from a gallery 7 in the cam shaft segment. Inward movement of the latching pins to disengage the cam shaft from the cam lobe is effected by the return springs.

Title: Magnetic propulsion system
Inventor: NEDIN MICHAEL FREDERICK
IPC: F03G3/00
Filed: 2003-06-12
Abstract: Apparatus and method for propelling a body by means of the repulsion of two magnetic fields. In one embodiment, a fixed electromagnet (1) is attached to a base (5) through a connection column (11). A moveable magnet (2, 19, 18, 16) is forced to the end of a respective cylindrical tube (6a, 6b, 6c, 6d) by means of centrifugal force. In the illustrated system, the tubular structure (6) is rotating and the electromagnets are retained at the end of the tubes by retainers (2). As a moving electromagnet comes into alignment with the fixed electromagnet (1), they are both energised at the same time creating magnetic fields (3) and (4), and the force induced on electromagnet (1) pushes the base (5) in a forwards direction, but the force induced on electromagnet (2) does not put any mechanical energy into the base (5) in a backwards direction, such that all or nearly all of the force is directed in the forward direction. The moveable electromagnet that has been energised will, however, have lost some of its centrifugal weight or force that has been placed within it due to centrifugal action. This, however, is replaced by the spinning action of the tubular structure.
