Title: Device for producing a granular material
Inventor: FROESCHKE REINHARD
IPC: B01J2/26
Filed: 1994-08-05
Abstract: Prior art belt-type droplet-forming equipment uses an outlet slit which is disposed at right angles to the direction of motion of the perforated belt (1) and through which the material can pass into perforations in the belt. The invention proposes that the slit is replaced by several rows of apertures, the rows being disposed next to each other in the direction of motion of the belt and the apertures in adjacent rows being staggered with respect to each other such that the total aperture area over which the perforations pass is constant, irrespective of the path of the perforations. This design makes it possible to reduce the force exerted on the perforated belt by the compound pressed out on to the belt. The device is suitable for use in belt-type droplet-forming equipment.

Title: Method for increased sensitivity of radiation detection and measurement
Inventor: MILLER STEVEN D
IPC: G01T1/10
Filed: 1994-03-07
Abstract: Dose of radiation to which a body of crystalline material has been exposed is measured by exposing the body to optical radiation at a first wavelength, which is greater than about 540 nm, and measuring optical energy emitted from the body by luminescence at a second wavelength, which is longer than the first wavelength.  Reduced background is accomplished by more thorough annealing and enhanced radiation induced luminescence is obtained by treating the crystalline material to coalesce primary damage centers into secondary damage centers.

Patent CA-2168979-A1 (CA)
Inventor: DEVINE JAMES P
IPC: B31D5/00
Filed: 1994-09-12
Abstract: An expanded paper cylinder formed from a spiral is disclosed as a void fill. A delivery system is provided for manual and automatic delivery of the expanded paper from a continuous, unextended wound roll of an extendible sheet material. The cushioning material formed by the expander can be used as an expanded sheet around an article or as void fill, or can be formed into spiral cylinders for use as void fill. The manual dispensing system includes a support member supporting a rotatable feed roll. A restraining device slows the free delivery of the wound feed roll of unextended sheet material, so that the sheet material expands while it is being drawn, under tension from the feed roll. An automatic system uses expander rollers to expand the slit paper and can be coordinated with apparatus which cuts and forms the spiral cylinders.
