Title: Method of continuous addition of a component to a chemical or biological system and apparatus therefor
IPC: C12M1/26
Filed: 1969-05-14
Abstract: 1312447 Device for introduction of reactant NATIONAL RESEARCH DEVELOPMENT CORP 13 May 1970 [14 May 1969] 24688/69 Heading B1X [Also in Divisions B8 and C6] A method of continuous addition of a substantially constant rate of a required component to a liquid chemical or biological system e.g. shake-flusk cultures of microorganisms, involves diffusing the added component into the system during the chemical reaction or biological process from a substantially rigid sealed container in part formed of diffusion membrane immersed in the system. In chemical reactions, slow addition of one reactant may be required in order to reduce to a minimum any secondary reaction of that reactant with the desired product. In biological processes, a metabolisable additive may be toxic to the organism in high concentrations. The component is diffused from a capsule formed in part of viscose cellulose film, collodion, or polyalkylene or halogenated polyalkylene film. Diffusion membranes and partitions resistant to caustic alkalis and strong acids, may be used, where required. The whole capsule, or just the membrane, may be immersed in the reacting system. A preferred container consists of a hollow cylinder 6, Fig. 2, and one or more membrane discs 3 held in position against an "O" ring 4 by an annular threaded cap 2. If the container is formed with two open ends, the other end may be closed with a cap 7 and gasket 8, or a further annular cap 2 and membrane disc 3. The container should be capable of withstanding internal pressures of up to 100 Kg/cm<SP>2</SP>. Examples are directed to the diffusion through membranes of glucose, lactose, valine, sodium glutamate, arginine hydrochloride and lysine hydrochloride.

Abstract: 1315664 Hauling cables POST OFFICE Aug 28 1970 [3 Sept 1969] 43538/69 Heading B8B Apparatus for the laying or recovery of repeater cables 8 comprises pairs of traction rollers 2, 3 resiliently biased together to grip the cable for traction or braking thereof, and pairs of guide rollers 4, 5, 6, 7 resiliently biased together to grip the cable to either side of the traction roller pair. Each traction roller includes a pneumatic tyre for engaging the cable and is driven by a motor/pump unit 12, which during cable laying acts as a brake for the traction rollers. Each of a pair of the traction rollers is mounted at one end of a pivoted bell crank lever 14, the other ends of which levers are connected together through a sliding block bearing whereby symmetrical movement of both levers occurs under the action of an hydraulic ram pivoted therebetween to maintain a constant biasing pressure. The pairs of guide rollers are similarly mounted on bell crank levers which are biased together by torsion springs, opposed levers of each pair being coupled together through toothed quadrants to synchronize their movements. Normally open hydraulic disc brakes are associated with the traction rollers. In the embodiment of Figs. 5 and 6 (not shown) adjacent pairs of guide rollers on each side of the cable are coupled by cable guiding skids. In the embodiment of Figs. 9-12 (not shown) the whole apparatus is suspended on leaf springs which permit limited longitudinal movement of the apparatus, load cells at both ends of the apparatus generating readings in response to fluctuations in tension in the cable being handled. In the embodiment of Figs. 14, 15 (not shown) traction rollers are mounted on both horizontal and vertical axes in alternating sequence longitudinally of the apparatus.

Abstract: 1323530 Pneumatic conveyers; shoots KERNFORSCHUNG mbH GES FUR 28 Oct 1971 50112/71 Headings B8A and B8S [Also in Division G1] Samples 15 and flow monitors 14 to be subjected to radiation and then to be delivered to separate measuring stations are secured to one end of a capsule 3 which is propelled pneumatically along a tube 5 to position the sample and flow monitors adjacent to the target 8 of a neutron generator 9. After radiation the capsule is returned to the other end of the tube 5 whereupon the sample and flow monitors are released from the capsule to drop down a shoot 6, the lower surface of which is formed by a pair of inclined rails 35 spaced apart a distance corresponding to the thickness of the flow monitors to allow some to pass therethrough and thence down a shoot 37 to a measuring station (not shown). The samples 15 which are thicker than the flow monitors pass down the rails to drop through an aperture 39 into a shoot 40 leading to another measurement station, not shown. The capsule 3 is substantially tubular in shape with ridges 16 at opposite ends to bear against the interior of the tube 5. Mounted within the capsule are three equi-angularly spaced arms 19 which are pivotally secured at one end to the capsule and project beyond the end face of the capsule at the other end to form a gripper for holding the sample and flow monitor in sandwich fashion. The arms 19 are urged towards each other by a rubber band 25 and have a wedge-shaped surface 13 for abutment with a disc 29 mounted on one end of a rod 18, the other end of which protrudes from the capsule to abut a stop 1 on the return of the capsule from the neutron generator. Such abutment forces the disc 29 along the surfaces to open the gripper and allow the sample and flow monitors to drop into the shoot 6. A spring 30 urges the rod 18 to return to its normal position.
