Patent CA-2356028-A1 (CA)
Title: Conveyor incorporating a modular frame construction
Inventor: ERTEL DANIEL E
IPC: B65G21/06
Filed: 2001-08-28
Abstract: A conveyor construction includes a conveyor frame formed of a pair of side frame members which are interconnected with each other via a bed plate which underlies an endless conveyor belt. The side frame members may also be interconnected by a bottom wall formed integrally with the side frame members and extending therebetween, or via a separate bottom plate member that is mounted to the side frame members. The bed plate and the lower plate are connected using a connection arrangement which enables the bed plate and lower plate to be connected to the side frame members at any point along the length of the side frame members. The connection arrangement includes slot-type engagement structure which extends throughout the length of each side frame member, and which is capable of receiving threaded fasteners, such as self-tapping screws, which extend through openings formed in the bed plate and the lower plate. In this manner, the side frame members can be selectively cut to a desired length and openings can be formed in the bed plate and lower plate at any location, and self-tapping screws can extend through the openings into engagement with the slot structure for mounting the bed plate and the lower plate to and between the side frame members. The side frame members define passages within which gear racks are received, and a rotatable pinion is engaged with the gear racks for providing extension and retraction of the gear racks upon rotation of the pinion. The gear racks engage head plates movably mounted to the side frame members, and a spindle is rotatably mounted to and extends between the head plates. In this manner, extension of the gear racks result in outward movement of the head plates, and thereby tensioning of the belt. When proper belt tensioning is attained, the head plates are secured in position using retainer members secured within T-slots formed in the side frame members. The spindles are mounted to the head plates via spherical bearings to provide proper belt tracking. The bearings are engaged with the spindle via endwise engagement structure.

Patent CA-2369135-A1 (CA)
Title: Control for an arc welding system
Inventor: ROTHERMEL RONALD R
IPC: B23K9/12
Filed: 2000-04-05
Abstract: An arc welding voltage control loop adjusts a pulsation parameter such as pulse width, pulse amplitude, background amplitude between pulses, or frequency, to compensate for deviations in arc voltage. A second, slower feedback loop adjusts a second parameter to cause the pulsation parameter to  return to a desired value due to the effect of the adjusted second parameter  on the arc voltage. The second parameter may be the torch-to-workpiece distance, adjusted via a proximity control motor (119) so that when the torc h- to-work distance begins to change due to misalignment or changes in workpiec e contour during torch movement along the weld path, the weld power source voltage control loop adjusts the pulsation parameter keeping the voltage equ al to the voltage command. The slower proximity control adjusts the torch-to- workpiece distance until the voltage control loop returns the pulsation parameter to its original value.

Patent CA-2383357-A1 (CA)
Inventor: RAPP HORST
IPC: A61P31/00
Filed: 2000-07-21
Abstract: The invention concerns the use of tosylchloramide(s), tosylchloramide salt(s ), their derivatives and/or the decomposition products for treating diseases of  the skin, mucous membranes, organs and tissues, excluding treatment of retroviral diseases (HIV) and disinfecting processes. It has been shown that  tosylchloramide compounds can be used even for all diseases of the skin and viral mucosa causing formation of vesicles and itching, and they can lead to  similar results as those obtained when they are used to treat corresponding diseases in tissues and organs. They not only provide quick relief of the acute symptoms and cure, but they also reduce frequency of recurrence. The inventive use is characterised in that it leads to very good treatment results, entirely independently of the form of preparation used, and it does  not have to be administered in one specific manner. Relatively low amounts o f tosylchloramide active principle can provide complete cure.
