Abstract: The present invention relates to a method and apparatus adapted to promote the recycling of complex articles, such as, in particular, printer cartridges, toner cartridges and other complex office items. The invention provides an apparatus having storage space arranged to store a number of such complex articles for recycling.  Access to the storage space is controlled by a data processor which interacts with a user byway of a visual display unit and control panel. If the user wishes to store an item, he indicates this by way of the control panel and the apparatus is then operable to open a receptacle to receive the used item. When the used item is placed in the receptacle, in preferred embodiments means are provided to determine that the used item is an article of an appropriate type to be stored. These means preferably employ shape recognition. The article will be rejected if it is not of the correct type and accepted and retained in a storage space if it is of the correct type. The preferred apparatus is also arranged to dispense items on request by the user. A preferred feature is that the apparatus will not dispense a new or recycled item if a predetermined ratio of new items dispensed to used items stored by that user would be exceeded. This encourages recycling.

Patent CA-2148634-C (CA)
Inventor: MARCINKIEWICZ JOSEPH G
IPC: H02P6/18
Filed: 1995-05-04
Granted: 1998-12-22
Abstract: A BPM or SRM electric motor (M) is supplied  bus  current.         A  PWM  inverter  (I) uses bus current to commutate the motor by systematically  energizing   and   de-energizing   the   motor's windings  (W)  with  the  current.   The  resultant  bus current waveshape  has  characteristics  that  are  a  function   of   a commutation  angle  between  a  rotor (T) of the machine and its windings.  The waveshape includes the effects of bus  ripple  or transients.    A   commutation   controller   (10)  samples  the waveshape   during   each   commutation   interval   to   obtain commutation  angle information.  The controller provides control inputs to an  inverter  (I)  to  control  commutation  angle  in response  to  the sample information.  Commutation angle control includes calculating a control  variable  (Icurve)  which  is  a function  of  commutation  angle.  This variable is comprised of sampled data values which are additively combined  according  to a  prescribed  formula  and  which  provide  a  high  degree  of linearity  over  a  wide  range  of  commutation  angles.    The controller   is   further  responsive  to  the  motor's  impulse response  (Hmotor(t))  to  reject  bus  ripple  effects  on  the waveshape  samples. By  employing  the  control  variable  and impulse response, the controller provides appropriate  frequency (fout)  and  voltage  (voutcorrected)  inputs  to  the  inverter to achieve an optimum  commutation  angle  relationship  between the rotor and windings.

Abstract: Non-aqueous rechargeable lithium batteries are often equipped with internal electrical  disconnect devices to protect against overcharge abuse. At the abnormally high voltages of overcharge, these devices can be activated by gasses  generated  as  a  result  of  the  electrochemical polymerization of suitable monomer additives incorporated in the electrolyte.  Aromatic compounds such as biphenyl are particularly suitable aromatic additives for LiCoO2 based lithium ion batteries.

Title: Reacteur pour le traitement d'un liquide
Inventor: AUGER RICHARD
IPC: C02F3/06
Filed: 1996-03-07
Granted: 2007-09-18
Abstract: La présente invention concerne un réacteur pour le traitement d'un liquide. Le réacteur comprend une enceinte remplie d'un lit absorbant. Une entrée est disposée dans la partie supérieure de l'enceinte pour introduire dans celle-ci à intervalle régulier un volume donné de liquide à traiter. L'enceinte comprend aussi une sortie disposée dans sa partie inférieure pour évacuer de celle-ci le liquide traité. Le lit absorbant est constitué d'une garniture poreuse capable d'absorber par capillarité le liquide introduit dans l'enceinte en vue de le traiter. Au moins un élément séparateur, perméable au liquide à traiter mais causant néanmoins au moins un bris de capillarité dans l'enceinte, est disposé horizontalement dans l'enceinte en vue de diviser le lit absorbant en au moins deux couches superposées d'une hauteur déterminée, calculée en fonction de la hauteur de la remontée capillaire du liquide à traiter dans une colonne remplie d'une couche continue du même lit absorbant. Le réacteur de la présente invention est peu coûteux à construire. Le temps de traitement est facilement contrôlable due à l'utilisation de la capillarité par la garniture poreuse, et grâce à ses éléments séparateurs, le réacteur peut ainsi être utilisé à un rendement optimal.

Title: Mechanism for feature improvement for bicycles and other crankdriven mechanism
Inventor: VEILBERG STEEN UFFE LAWAETZ
IPC: B62M1/36

Granted: 2006-11-14
Abstract: In the case of bicycles, the purpose of the new construction is to make maximum use of the momentum produced by pedalling under varying ground conditions, load, and acceleration--thus making bicycling easier. The construction has two variable positions which reduce the time during which the pedals are in a dead position (top and bottom) and prolong the time where the pedals are at right angles (16) whereby maximum effect is gained from the power force. This applies if the direction of force is non-circular, i.e. when there is a rise of the ground, and under acceleration as well as "standing pedalling". New positioning is possible in relation to the pedal arm (18), i.e. when changed ground conditions (rise) cause the center of gravity (pedalling) to shift. The invention differs from existing ones in that them is "increased"  angular velocity between the driving shaft (1) and driven shaft (2) when they are on the same level and have the same longitudinal direction, which is the easy in this construction. Also, the special suspension obtained by means of three moving rings (3) (4) (5) (like cardan suspension) of which the change of angle and vertical position (4) of the second ring together with the manually controllable parts (16) (18) produce the above-mentioned increased angular velocity and its position in relation to a given center of gravity. (9) shows an exterior bearing.

Abstract: In this equipment for the production of the load in a lift cage (3), a motor (4) drives a drive pulley (5), over which a hoist cable (6) is guided. A carrying frame (7) is arranged at one end of the hoist cable (6) and a counterweight (8) is arranged at the other end of the hoist cable (6). The lift cage (3) rests on spring elements (9), which bear on the carrying frame (7). A belt (12), which is guided by way of a first deflecting roller (10) and a second deflecting roller (11), is coupled mechanically with the lift cage (3). The movement of the lift cage (3) is transmitted to the belt (12), which drives a pulse generator (13) coupled to the first deflecting roller (10).    In the case of changes in load, the spring elements (9) are compressed to a greater or lesser extent according to their characteristic, whereby the lift cage (3) moves relative to the carrying frame (7), which is in tum detected by the pulse generator (13) and translated into a travel signal (SL). From this, an evaluating unit (18) determines a load magnitude which influences a motor current (IW).
