Abstract: An inducible promoter is used to regulate expression of a gene which is known to be critical in microsporogenesis, i.e., the production of pollen. The selected gene's control sequences are modified so that it is normally "off" and as a result the plants are male sterile. When it is desired to reproduce the male sterile plants, male fertility is restored by treating the plants with a non-phytotoxic chemical which induces expression of the critical gene.

Abstract: A process for controlling the regeneration of boron trifluoride catalyst complexes in the production of carboxylic acids and other products using boron trifluoride hydrates as a catalyst. Catalyst strength is determined by measuring the electrical conductivity of the catalyst recovered from hydrolysis. If the conductivity is greater than a predetermined value, the hydrolysis water rate is reduced and if the conductivity is leas than a predetermined value, the hydrolysis water rate is increased. Conductivity is determined by a toroidal conductivity sensor and a control valve responsive to operation of the conductivity sensor serves to increase or decrease the flow rate accordingly.

Abstract: A method of forming a tissue equivalent is described. A length of polyester tube is threaded over a mandrel (H) and attached at either end by clips at A and D. A block (F) is then screwed into place. The polyester is then pre-soaked by injecting through Tap (2) an acidified collagen solution for approximately one hour. After a suitable period of time the excess solution is aspirated off. Following this stage, a second, alkaline solution is injected into the apparatus which contains smooth muscle cells (SMC). Thus, neutralisation of the collagen impregnated within the fabric of the tube occurs leading to spontaneous fibrillogenesis within the interstices of the cloth, eliminating the risk of delamination. The apparatus is then incubated. The collagen contracts down onto the fabric tube and the cell-impregnated gel becomes incorporated into the presoaked collagen. The pre-impregnated collagen and the collagen provided in the aqueous mixture contract down as one into a coherent whole with the SMC. The tissue equivalent is then lined with endothelial cells and the apparatus again incubated and fed at increasing intraluminal pressures applied either statically or dynamically. This is believed to cause the vessel to become preconditioned to the pressure it will work under as an implant. This allows organization of the basement membrane which in turn promotes EC attachment and theoretically prevents smooth muscle cell hyperplasia.

Abstract: A method and apparatus for separating from a mixture materials having different specific gravities which can operate in a continuous manner and can separate particles of materials of non-uniform grain size. Water or other fluid is passed upwardly through an apparatus having an upper funnel in which is disposed a rotatable agitator having vanes or paddles which pass close to riffles on the wall of the funnel. Material to be separated is fed into the funnel and the upward flow of fluid is adjusted so that material of low specific gravity is carried up the funnel to an overflow discharge. With the agitator rotating, fine particles of the material to be separated and having a specific gravity higher than a certain figure are captured in "dead-zones" created behind the riffles and move down through the fluid to a discharge tube. Larger particles of the material to be separated move down through the upward flow of fluid to the discharge tube. The supply of fluid is periodically momentarily interrupted to eject material collected in or just above the discharge tube.
