Title: Method and an apparatus for waste handling
Inventor: WESTIN IVAR
IPC: B07C5/34
Filed: 1990-03-21
Abstract: A method and an apparatus for sorting waste into different waste types. A first division of the waste is effected into at least two waste types in that each waste type is placed in a bag (100, 101) which is provided with at least one marking which indicates the waste type for which the bag is intended. The containers are collected and mixed together for transport to a common sorting plant in which the containers pass indentification means (6) establishing, with the aid of the marking on the bag, the type of waste for which the bag is intended. The information is transmitted to recording and control means (7) which, via signal transmission means (73) switches a separating means (9) for adjusting the same into a position entailing that the bag, on its passage of the sorting plant, is brought into a position reserved for that type of waste indicated by the marking on the container. An apparatus according to the invention includes a first conveyor or storage feeder (1), a second conveyor (2), a distribution conveyor (3), an identification conveyor (4), unloading means (5), identification means (6), recording and control means (7) and separating means (9).

Inventor: BURKE ROBERT
IPC: A43B13/14
Filed: 1991-09-12
Abstract: A sole member for an article of footwear, comprises a sheet of resilient material displaying cushioning and memory properties.  The sheet has a generally longitudinal cavity with outwardly flared sidewalls that deflect horizontally in the presence of a downward force.  The cavity is wider in the heel region and curves outwardly toward the lateral forefoot to create a path of least resistance that causes the centre of mass of the human body to migrate laterally and thereby reduce predisposition to excessive pronation.
Patent CA-2054007-A1 (CA)
Title: Method and Apparatus for Production of Fuel
Inventor: SORRENTI JOHN
IPC: F02M21/02
Filed: 1991-10-23
Abstract: A method and apparatus for the production of a fuel from the decomposition of water and the subsequent use of this fuel as an energy source in an internal combustion engine or in a system for generating heat.  The method comprises the steps of:  a)    mixing water and a hydrogen-based source material under pressure to create a mixture;  b)  creating turbulence in said mixture;  c) heating said mixture to the point that the water molecules within the mixture begin to dissociate.  The apparatus of the present invention comprises a first pump to pressurize water and a second pump to pressurize the hydrogen-based source material.  The pressurized water and hydrogen-based source material are pumped into a mixing tank where they form a mixture.  A turbulence-creating mechanism is connected to the mixing tank and the mixture is passed through the turbulence-creating mechanism where it is heated to a temperature sufficient to cause decomposition of the water molecules therein.   The mixture is heated to this temperature by a heat applying mechanism which contacts the turbulence-creating mechanism.  The mixture is ultimately fed into a combustion chamber where it is ignited by a combination of compression and a spark from a spark plug.
Patent CA-2058432-A1 (CA)
Title: Colour monitoring
Inventor: JAWAD SAJAD M
IPC: G01N21/27
Filed: 1990-06-15
Abstract: Colour changes in a target, such as a chemical sensor using a colour-changing indicator reagent to detect the presence of a poisonous gas, are continuously monitored by reflecting the target (10) on to a sensor (16) light originating from first one and then another light source (12a, 12b, etc), each having a different, known emission wavelength. In each cycle, direct light from the appropriate source is also collected by another sensor (14), connected in a closed loop (26) with circuitry in which the emission intensity is compared with a known reference value (38) and which adjusts the emission intensity so as to stabilise it at this constant reference value. Once this is stabilised, the reflected light intensity signal is passed to a data store (20), after which a divider (22) produces an output signal (36) representing the ratio of the reflected light intensities in two separate cycles originating from two different light sources (12a, 12b, etc). The conduct of each cycle is controlled by timing means (18). Where there are two light sources, the wavelength of the second (12b) is outside the response range of the target, that of the first (12a) being at or near the peak target response, so that all the divider output signals represent successive values of actual reflected light intensity. These signals can be processed to show the rate of colour change in the target and used to operate e.g. an alarm.

Title: Plastic bag with reusable neck closure band
Inventor: LIPES ARNOLD
IPC: B65D33/24
Filed: 1992-01-23
Abstract: PLASTIC BAG WITH REUSABLE NECK CLOSURE BAND     ABSTRACT     A reusable neck closure band for a plastic bag and a method of securing same to a bag is disclosed.  A closure band is formed from an elongated rectangular strip of plastic material and comprises a neck retention portion for retaining a bunched neck portion of the bag, and opposed free band portions.  The neck retention portion is attached to the bag by a heat fused attachment.  A detach-able seal interconnects the free band portions together adjacent the bunched neck portion to restrain the bunched neck portion.  The detachable seal is disconnected by pulling the free band portions away from one another to cause the detachable seal to detach to free the bunched neck portion of the bag.  The bag is reclosable by tieing the free band portions together about a reformed bunched neck portion.

Abstract: A multiple latched accumulator fractional-N synthesizer for use in digital radio transceivers is disclosed. The divisor of the frequency divider (103) of the synthesizer is varied with time by the summation of accumulator carry output digital sequences which result in frequency increments equal to a fraction of the reference frequency. The accumulators (615, 617) are latched such that upon the occurrence of a clock pulse, data is transferred through each accumulator one clock pulse step at a time, such that the delay through the system is equal to that of only one accumulator. The carry outputs of the accumulators (616,617) arc coupled through delays (645, 647, 649, 631, 633) equal to one less delay than the number of accumulators and added (635) such that all higher order accumulator carry outputs add to a net summation of zero so as to not upset the desired fractional setting of the first accumulator.

Abstract: Système numérique virtuel d'annulation active de terre (14). Le système reçoit un signal d'entrée (r) représentant des phénomènes résiduels à annuler, et est doté d'un filtre adaptatif (44) qui produit un signal d'annulation (y). Une réponse impulsionnelle du système (c) est convolutionnée avec le signal d'annulation (y) et soustraite du signal d'entrée (r) afin de produire une estimation de bruit (x). Le filtre adaptatif (44) produit le signal d'annulation (y) en filtrant le bruit estimé (x) avec un poids de filtre (a) adapté par la réponse impulsionnelle (c) du système. En convolutionnant l'estimation du bruit (x) avec l'impulsion du système (c) afin d'adapter le filtre (44), on peut conserver les valeurs envoyées à un adapteur (50) pour le filtre adaptatif (44) avec un déphasage d'au plus 90 degrés du signal résiduel (r). Cela élimine en bonne partie les problèmes associés à la rétroaction destructive due à des déphasages sans nécessiter le recours à des signaux de référence externes.
