Patent MX-168008-B (MX)
Inventor: BERENS ALAN ROBERT
IPC: C08J3/20
Filed: 1986-10-17
Abstract: A process is described for infusing an additive into a polymer using a compressed fluid that is normally a gas at room temperature and pressure. The additive must have some degree of solubility in the compressed fluid and the solution of compressed fluid and additive must have some degree of solubility in the polymer. In accordance with the process, the solution of the normally gaseous fluid and additive and the polymer are brought into contact under pressure until a desired quantity of the solution is absorbed into the polymer. The compressed fluid then is diffused from the polymer leaving additive infused within the polymer.

Patent NO-178165-B (NO)
Inventor: SCHIEFER ERWIN
IPC: F16B1/00
Filed: 1992-05-15
Abstract: On the contact surfaces formed by the inner contour of the expanding sleeve (7) and the outer contour of the expansion of the shank (2), an expanding dowel has a friction-reducing coating (10). Said coating (10) produces a friction level between the expanding sleeve (7) and the expansion (3) of the shank (2) which is less than the friction level between the expanding sleeve (7) and the wall of the drilled hole. The friction difference thus produced causes a reliable subsequent expansion behaviour of the expanding dowel in the cracked tension zone. In addition to the coating (10), projections (11, 12) are arranged on the outside of the expanding sleeve (7), which projections (11, 12) are located one behind the other and maintain the contact with the wall of the drilled hole in the event of relatively large displacements of the expanding dowel, primarily in the cracked tension zone.

Inventor: BROWN E
IPC: H04N7/34
Filed: 1972-06-12
Abstract: This disclosure relates to real time, all digital, video receivers wherein a linear light modulation is achieved by means of a "half-tone process." The half-tone process is effected by gating a linearly scanned electron beam with constant amplitude, variable duty cycle pulses. The duty cycle is varied in successive Nyquist intervals in a manner directly related to the binary digit content of the successive n-bit words of a received pulse code modulated (PCM) video signal. For a 7-bit conventional PCM video signal, for example, 128 different levels of light intensity can be provided for each Nyquist interval.

Title: Spray crystallization
Inventor: RUSHTON WILLIAM E
IPC: B01D9/02
Filed: 1983-11-14
Abstract: A method and apparatus for the crystallization of solids from liquids includes a vessel (8) having an elongate vertical spray chamber (10) which overlies and is in flow communication with a collection basin (22) for collecting slurry from the spray chamber. The collection basin has a cross-section larger than the cross-section of the spray chamber and preferably includes a side wall (24) which extends upwardly beyond the lower end (18) of the spray chamber (10) to define an opening between the wall of the basin and the spray chamber which communicates with the atmosphere. A blower (14) is located in the top of the spray chamber to draw air at substantially ambient atmospheric conditions through the opening between upper end of the basin and lower end of the spray chamber and upwardly through the chamber (10). The slurry solution which is to be concentrated and crystallized is sprayed into the chamber and directly contacts the air flowing through the chamber thereby resulting in evaporation and concentration of the sprayed slurry and and crystallization of solids therefrom. The slurry collected in the collection basin is recirculated and returned as a spray at the upper end of the chamber. If desired, the recirculated slurry may be heated prior to being returned as a spray at the upper end of the chamber and the heating may be achieved in a heat exchanger (36) so as to utilize waste heat in its operation; this may also be employed to condense the otherwise wasted vapour from a series of vacuum evaporators and further concentrate the product.

Title: Method for producing a split leather and the use thereof
Inventor: SCHMIDT GUNTER
IPC: C14B1/00
Filed: 1990-11-30
Abstract: To make split leather, a limed animal hide is split into a grain split and a flesh split, the flesh split is divided into a butt and a neck and flank part and the butt is relimed, bated, chrome-tanned, fat-liquored, dried and dressed. Here low-shrinkage split leather is obtained by first reducing the butt, between the chrome-tanning and the fat liquoring, to a thickness of 1.1 to 2.5 mm by shaving on the split and flesh side, retanning, and, after the dried butt has been dressed on the split side, producing from it a middle split 0.5 to 1.0 mm in thickness by shaving on the flesh side, and subsequently dressing the middle split also on the flesh side. This low-shrinkage split leather is particularly suitable for two-dimensionally adhered leather trim subjected to temperature and humidity changes, in particular in motor cars.
