Patent CA-2050051-A1 (CA)
Title: Method of printing non-visible messages and revealing the same
Inventor: DUNN JONATHON B
IPC: B41M5/124
Filed: 1991-08-27
Abstract: ABSTRACT            The invention provides a substrate having an invisible message that is revealable.  Previously such substrates had an opaque layer sprayed over the message which then had to be scratched off.  The substrate of the invention is formed of a recording sheet upon which is a first image forming component that is capable of reacting with a complementary image forming component to produce a visible reaction product.  The first image component is arranged on the recording sheet in a pattern corresponding to the positive or negative image of a desired message.  Alternatively the recording sheet has a desensitising component on it that is arranged in a pattern corresponding to the positive or negative image of a desired message.  In use, the desensitising component prevents the formation of the visible reaction product when the complementary image forming component is applied on the first image forming component.

Title: Garbage dump
Inventor: HODRI GEORGE
IPC: B65G3/02
Filed: 1991-09-18
Abstract: Abstract of the Disclosure Title: GARBAGE DUMP     A waterproof cover is placed over the garbage heap, and the heap rests in a sealed basin.  A collection system collects liquids and sludges at the base of the heap and sprinkles the liquid on top of the heap.  The liquid collection system includes a tower, whereby liquid may be drawn off above a layer of accumulated sludge.  A gas collection system collects methane etc rising in the heap.  An air distribution system supplies air underneath the heap, through independent outlets.  A heating system, powered by the collected methane, corrects any cool spots in the heap. Bio-chemical parameters are computer controlled.  The heap of garbage accordingly undergoes rapid decomposition, and the dump can then be re-used.  The garbage is pre-sorted, whereby the decomposed material is suitable as fertiliser.
