Abstract: In order to improve the adhesive strength of metal/plastic composite systems, it is known to apply silane solutions to pretreated metal surfaces. The solutions used are expensive, the special processes are complex, and the surfaces treated in this way require immediate further processing. Pretreated alloy surfaces are   - either blasted with amorphous quartz powder, etched with hydrofluoric acid, rinsed with distilled water and coated with an adhesion promoter before the plastic is applied; - or the alloy surface is either moistened with silane solution and blasted with quartz sand (particle size 20-500  mu m), or blasted with silanised quartz powder having a particle size of 20-500  mu m, - or sprayed with silane solution and simultaneously blasted off with amorphous quartz powder (particle size 20-500  mu m). The surface pretreated in this way is coated with a known adhesion promoter (coupling agent), preferably at a reduced pressure of 1-50 Pa, and the plastic is applied thereto. The process is suitable for the production of a reliable bond with high pressure shear strength of plastics to metals.

Abstract: A metering device for fluid, especially for metering lubricating oils, which ensures precise and repeatable metering of the fluid portions irrespective of parameter changes in the system in which it is installed, has a simple and technological design and permits unification of the elements which comprise it. The metering device comprises a body in which an input channel (2) and an operating chamber (3) are formed centrally, which chamber, for its part, is closed by a hollow nut (7) with a central, step-shaped through-opening (9). A lower-spring plunger (5) is mounted loosely in the operating chamber (3). According to the invention, the transition from the operating chamber (3) to the input channel (2) is a conical surface (4). Such a conical surface mates with the surface of the plunger lying on it. This plunger is produced from an elastic material and a cavity which is open on one side is formed in it from the side of the input channel. <IMAGE>

Patent EP-0408193-A1 (EP)
Inventor: LOPEZ ALFRED R
IPC: B64D45/04
Filed: 1990-06-12
Abstract: In the ground-based equipment of a microwave landing system (MLS), a linear array antenna is employed to generate both a scanning guidance beam, which provides azimuthal position data to an incoming aircraft, and a pair of out-of-coverage indication (OCI) beams, which are disposed outside of the sector covered by the scanning guidance beam. For sweeping the guide beam, phase shifts are updated in a linear phase gradient to scan the beam to the right and to the left of the centerline of the antenna. To form the pair of OCI beams, the main lobe of the antenna radiation pattern is directed to one side of the antenna's centerline, outside the normal scanning range, thereby producing a grating lobe on the opposite side of the centerline. Furthermore, a quadratic phase shift function is superimposed upon the linear phase gradient to de focus the OCI beams so as to fill a sufficient sector of space, on both sides of the scanned region, for OCI coverage.

IPC: C12R1/38
Filed: 1990-07-20
Abstract: The invention is a process for controlling the expression of heterologous genes from  lac -operated promoters by removing the CAP binding site and  lac  promoter from the  lac  operon. Illustrated is the fusion of the  lacZ ,  Y , and  A  genes of the  lac  operon to the 3′ end of the  lacI  structural gene. This elimination of the natural regulatory elements of the  lac  operon results, advantageously, in the production of  lac  operon gene products in a constitutive mode from the  lacI  promoter.

Title: Perfusive chromatography
Inventor: AFEYAN NOUBAR B
IPC: B01J20/285
Filed: 1990-02-20
Abstract: Disclosed are chromatography methods and matrix geometries which pernmit high resolution, high productivity separation of mixtures of solutes, particularly biological materials. The method involves passing fluids through specially designed chromatography matrices at high flow rates. The matrices define first and second interconnected sets of pores and a high surface area for solute interaction in fluid communication with the members of the second set of pores (14). The first and second sets of pores are embodied, for example, as the interstices among particles and throughpores (14) within the particles. The pores are dimensioned such that, at achievable high fluid flow rates, convective flow occurs in both pore sets, and the convective flow rate exceeds the rate of solute diffusion in the second pore set. This approach couples convective and diffusive mass transport to and from the active surface and permits increases in fluid velocity without the normally expected bandspreading. <IMAGE>

Abstract: This is an improved method of fabricating Zircaloy-4 strip. The method is of the type wherein Zircaloy-4 material is vacuum melted, forged, hot reduced, beta-annealed and quenched, hot rolled, subjected to a post-hot-roll anneal and then reduced by at least two cold rolling steps, including a final cold rolling to final size, with intermediate annealing between the cold rolling steps and with a final anneal after the last cold rolling step. The improvement is characterized by the steps of: (a) utilizing a maximum processing temperature of 620°C between the quenching and the final cold rolling to final size; (b) stress relief annealing at a maximum intermediate annealing temperature of 520°C; and (c) utilizing hot rolling, post-hot-roll annealing , intermediate annealing, and final annealing time-temperature combinations to give an A parameter of between 4 x 10⁻¹⁹ and 7 x 10⁻¹⁸ hour, where segment parameters are calculated for the hot rolling step and each annealing step, the segment parameters are calculated by taking the time, in hours, for which that step is performed, times the exponent of (-40,000/T), in which T is the temperature, in degrees K, at which the step is performed, and where the A parameter is the sum of the segment parameters. Preferably, the hot rolling                                and the post-hot-roll anneal are at 560-620°C and are for 1.5-3 hours and the intermediate annealing is at 400-520°C and is for 1.5-15 hours and the final anneal after the last cold rolling step is at 560-710°C for 1-5 hours, and the beta-anneal is at 1015-1130°C for 2-30 minutes.
