Filed: 1987-06-12
Granted: 1991-09-04
Abstract: An asymmetrical membrane of polyester-amide, useful in dialysis processes and in ultra-filtration processes in general, is formed by a polyester-amide with repetitive units (TATE)n (wherein T is the terephthalic acid radical; A is the hexamethylenediamine radical; and E is the hexanediol radical), shows a thickness of from 15 to 190  mu m, a water permeability value of up to about 9 litres/m<2>/hour, for a  DELTA P of 300 mmHg and a good permeability for substances having a molecular weight of up to about 17,000. Such an asymmetrical membrane is obtained by means of a process which comprises the following steps, carried out sequentially: - preparation of a solution of polyesteramide (TATE)n in a solvent constituted by formic acid at a concentration higher than about 99%, or constituted by a solution of lithium chloride in dimethylformamide or dimethylacetamide; - spreading of said solution on a flat support, to a layer of from about 20 to about 200  mu m of thickness;  - dipping of the coated support in an aqueous coagulation bath; washing with water and recovery of the so-obtained asymmetrical membrane.

Abstract: The anti-theft product rack (10) continuously monitors the weight of the rack including individual product units (12). When a weight deviation is detected (16), it is characterized as either a disturbance or as the removal of one or more product units. An alarm (41) is sounded if the rack is continuously disturbed for a programmable number of continuous weight sensing cycles, or if a programmable number of disturbances occur during a programmable period of time. In addition, an alarm is sounded if the number of product units detected as being removed at one time exceeds a programmable limit. Finally, if the number of detected product units removed exceeds a programmable number during a programmable period of time, an alarm is sounded. The product display rack presents no physical barriers to product removal and requires no intervention of sales personnel for product removal. Thus, the present invention presents an aesthetically pleasing product rack while providing a high degree of protection against shoplifting or employee theft.

Abstract: In this method, the circuit boards are first fabricated with conductive areas which are to be provided with a solder application, after that, these areas are bounded by a boundary layer of defined layer thickness, which essentially corresponds to the height of the solder application to be produced, which prevents dip soldering. Then, the circuit board thus prepared is introduced into a solder bath, in the solder bath, a cover device is applied to the top of the boundary layer so that the complete volume of the solder lying above the areas is held fast on emergence of the circuit board until it solidifies. The method makes it possible to achieve solder applications with a layer thickness of between 10  mu m and 500  mu m and approximately rectangular cross-section.

Inventor: JOHNSON ROBERT G
IPC: G01F1/684
Filed: 1989-12-20
Granted: 1995-09-06
Abstract: The marginal adhesion of platinum to silicon nitride is a serious issue in the fabrication of microbridge mass air flow sensors. High temperature stabilization anneals (500-1000 DEG C) are necessary to develop the properties and stability necessary for effective device operation. However, the annealing process results in a significant reduction in the already poor platinum/silicon nitride adhesion. Annealing at relatively high temperatures leads to the development of numerous structural defects and the production of non-uniform and variable sensor resistance values. The use of a thin metal oxide adhesion layer (44, 46), approximately 20 to 100 angstroms in thickness is very effective in maintaining platinum (45) adhesion to silicon nitride (42, 47), and through the high temperature anneal sequence. Moreover, incorporation of the thin metal oxide adhesion layer (44, 46) minimizes the development of structural defects, and results in significantly improved uniformity and control of platinum sensor/heater resistance characteristics.
