Title: Improvements relating to biotransformation reactions
Inventor: MAVITUNA FERDA
IPC: C12M3/00
Filed: 1985-11-07
Abstract: A method of effecting biotransformations comprises, as a first step, the fixation of biological material from suspension by passing suspension through a liquid permeable member which is capable of filtering the biological material. The liquid permeable member is an integral body or a composite body whose components are maintained in a substantially fixed relationship to each other. The biological material may comprise living or biochemically active cells and/or tissues and/or particles which themselves comprise pre-immobilised biocatalysts. After fixation, the biochemical transformation is effected by contacting the biological material supported on the member with a liquid and/or gaseous medium to form a product and/or biomass. Finally, the product is recovered and/or the biomass is harvested. Various apparatus for effecting the fixation of the biological material are described and generally incorporate means for establishing a relative velocity between the liquid permeable body and the suspension so as to effect the filtration. Also described are reactor systems comprising biological material which has been entrapped by fixation on a liquid permeable support body. The invention may be applied to the fixation of plant cells for growth into "plantlets" (i.e. micropropagation).

Title: A spring motor
Inventor: MA LOUIS KAM KONG
IPC: A63H29/04
Filed: 1986-02-04
Abstract: The rear wheels of a toy motor car are fixed to a horizontal shaft (11) connected to the driven gear (6) of a spring motor. The motor incorporates a spiral spring mounted in and connected to the housing (1), and coupled to a driving gear (2). A stepped pinion (7 and 8) is mounted in engagement with the driving gear (2) and vertically above the driven gear (6) on a shaft (9) which extends through vertical slots (10) within the housing (1). A winding cord (5) is wound around a drum (4) attached to the driving gear (2) so that when the end (17) is withdrawn from the vehicle, the gear (2) is rotated in reverse direction to wind the spring (3), and this reverse rotation lifts the stepped pinion out of engagement with driven gear (6) so that the driving wheel of the vehicle are not rotated. On release of cord (5), the spring (3) rotates the driving gear (2) in the driving direction. The resultant force transmitted from the driving gear (2) to the stepped pinions reinforces the weight of the stepped pinion in urging the stepped pinion to mesh the driven gear (6) and thus rotate the driving wheels of the car. <IMAGE>

Title: An engine control unit for a turbomachine
Inventor: ANNING ANDREW JOHN
IPC: F02C9/28
Filed: 1988-04-05
Abstract: An engine speed control unit for a gas turbine engine, e.g. an aircraft jet engine, is operative to adjust the level of fuel flow and incorporates in the control loop means for smoothing the rate of acceleration or deceleration to a newly demanded speed to avoid overshooting or undershooting the new speed. This is particularly effective when decelerating to a new low speed by avoiding engine speed undershoot and thus the subsequent re-acceleration which can cause a surge. The deceleration curve is smoothed controlling the rate of deceleration by substituting a false demand level NHd for the newly demanded speed PLd, and by progressively reducing the substituted level in an iterative control process so that actual engine speed NH is substantially assymptotic to the demanded speed after roughly four iterations. <IMAGE>
