Title: Method for the preparation of integral shaped replications of shaped, porous and dissolvable materials for use as adsorbents in fixed bed adsorption processes
Inventor: LESTER GEORGE RONALD
IPC: B01J20/28
Filed: 1982-03-19
Granted: 1986-01-23
Abstract: Integral shaped replications which may be used as supports for catalysts or as adsorbents comprise a carbonaceous pyropolymer structure which has been prepared by treating a substrate material with an organic pyrolyzable precursor compound and pyrolyzing the precursor at 500 to 1200 DEG C, in a reducing atmosphere to form a carbonaceous pyropolymer possessing recurring units containing at least carbon and hydrogen atoms on the surface of the substrate material. This carbonaceous pyropolymer duplicates the physical shape and dimensions of the substrate material as well as a substantial portion of the pore structure thereof. The integral shaped replications possess an apparent bulk density (ABD) which is 25 to 100% of the ABD of the inorganic support, and have a crush strength of from 0.5 to 14 kilograms. The composite comprising the carbonaceous pyropolymer on the surface of the substrate material is then bleached with a dissolving agent to remove the substrate material, thus leaving a shaped replication of particle aggregates, if so desired, the shaped replication may be further treated by depositing at least one inorganic oxide on each surface of the replication and or by depositing at least one catalytically active metal and optionally removing the carbonaceous pyropolymer by oxidation.

Inventor: READINGS PETER BERT
IPC: G03F1/00
Filed: 1982-03-19
Granted: 1986-07-24
Abstract: A relief image-forming composition having an acidic pH comprises a photosensitive component and an indicator capable of existing in two states differing in actinic opacity dependent upon pH. A relief image is formed by (1) exposing to light selected areas of a layer of the composition, the indicator being in its state of lower actinic opacity, (2) removing layer material from the exposed areas or from the unexposed areas and (3) shifting the pH in the remaining layer material to a value at which the indicator exists in its state of higher actinic opacity. The resultant image can then be used as an intermediate original in diazotype copying processes.

Granted: 1988-08-04
Abstract: Rows of ten filled hypodermic syringes, without rods and in depending position, are transferred successively from ten-row trays to a rail conveyor by a gang chuck having ten expandable inserts which enter and lift the syringes by their open piston ends. The syringes are conveyed to like chucks on a turret and carried thereby in closely spaced sequence through two inspection stations. Ahead of the first station, they are spun rapidly and then stopped to leave their contents spinning for inspection for suspended particles. in the second, the syringes are rotated slowly to aid inspection for gross defects. Syringes found defective are pulled off their chucks manually by the inspectors and dropped to a chute for reject syringes. Accepted syringes are transferred in vertical position from the turret to an angled delivery wheel, which tilts them to a horizontal position and delivers them to a conveyor leading to a rod inserting machine and labelling and packaging mechanism.

Date Apr. 10, 1986.This invention relates to a process and a device for adjusting a photographic color enlarging or copying apparatus. By means of the measuring device that uses copying light of the enlarging apparatus to be adjusted as the measuring light, the color densities of a test copy made of a test original and of a reference copy which represents a satisfactory picture reproduction of the test original are measured selectively in the colors red, green and blue and are compared with one another. Corresponding to an existing deviation, adjusting control means at the enlarging apparatus that color-selectively influence the amount of copying light are readjusted until the deviation is balanced, and another test copy is made with the new exposure conditions and is measured.
