Patent CA-2024481-A1 (CA)
Inventor: KUNREUTHER STEVEN
IPC: B26D7/18
Filed: 1990-08-31
Abstract: Labels in sheet form are first separated into strips along spaced parallel perforation lines extending in the direction of sheet movement and then into individual labels along spaced perforation lines extending in a direction transverse to sheet movement.  The strip separation step can be accomplished with one of three ways.  The first embodiment includes a two driven pressure rollers one of which has a resilient exterior surface including discontinuous alternating larger and smaller diameter areas and the other has a rigid continuous surface of different diameter sections.  The rollers cooperate to clamp the sheet at points between the perforation lines as it moves and exert to a force along the perforating lines to burst same.  The second embodiment involves moving belts which clamp the sheets between the perforation lines as it moves, gradually separating into different planes.  The third embodiment includes a reciprocating element with fins and a pressure pad with slots aligned with the perforation lines to accomodate the reciprocating fins.  Transverse separation is accomplished by first and second spaced pairs of rollers.  The second pair of rollers is rotated at a higher speed than the first pair such that the labels are completely separated.  The individual labels can be accumulated on a slowly moving conveyor.

IPC: A63B21/072
Filed: 1991-01-09
Abstract: ABSTRACT         A golf swing muscle strengthener and swing developer device have a suitable structural member attached to a golf handle.  The member mat be curved or made up of L shaped members that are clamped to the handle.  If L shaped members are used, they are slidablely connected to each other.  Weights suspend from the member so that they are directly below the golfer's grip.  If a curved member is used, a means for adjusting weights is provided so as to located the weights properly.  The weights are suspended from the member by a single member or a member made up of the two parts; two members that permit one to telescopically side into the other.  There is no restraint of the weights at their upper and so that when they move a noise and vibration are observable; however, as the user becomes acquainted with the feel of a correct swing, and upper restraint may be added.  If the noise of vibration are not easily observable, a light or sound generating device or a combination of both may be provided.

Title: Sampling device with a valve unit and a receiving unit
Inventor: IFF RENE
IPC: G01N1/14
Filed: 1991-01-09
Abstract: The receiving unit can be removed from the valve unit and fastened preferentially by means of a fast locking means, in particular of a bayonet lock, a thread or a plug-in lock. The valve unit is spring-biased in the closing direction and opens toward the inside. The receiving unit is spring-biased in the closing direction and opens toward the outside. The valve unit and receiving unit are linked in sealing connection preferentially by means of mating ball joints. At the valve unit a discharge bore hole may lead from the discharge opening toward the outside, the valve bar being located outside the discharge bore hole.      At the lock the lock bar may extend outward from the opening of the receiving unit. The actuating device acts on the lock of the receiving unit preferentially by means of a two-part driver device with a cam coupled to the lock housing, and a recess arranged at the lock bar. A locking device preferentially permits the opening of the lock only if the receiving unit is arranged at the valve unit and locked in a predetermined actuating position in relation to it.

Title: Orthotic insert for shoes
Inventor: BROWN DENNIS N
IPC: A43B17/02
Filed: 1991-01-16
Abstract: An orthotic insert adapted to be placed within a shoe having an insole.  The orthotic insert has a relatively rigid, resilient base member having a heel portion and an arch portion. The upper surface of the base member is contoured to fit the plantar surface of a person's foot, so as to position the foot in a generally desired angular orientation.  At least one curvilinear ridge is formed on the lower surface of the base member, and extends continuously around the rearward end of the heel portion and along the arch portion on both sides of the longitudinal axis of the orthotic insert.  The ridge has a sharp lower edge which projects downwardly from the lower surface of the base member for supporting the heel seat in the heel section above the insole when the orthotic insert is placed within the shoe.  The lower edge of the ridge is adapted to have material incrementally removed therefrom so that the angular orientation of the foot can be adjusted to suit an individual person. The sharp lower edge of the ridge penetrates into the upper surface of the insole to maintain the insert in position, when the person's weight is applied to the upper surface of the orthotic insert.
Patent CA-2035222-A1 (CA)
Inventor: CHMIEL STEVEN F
IPC: H02P1/44
Filed: 1991-01-29
Abstract: A capacitor-start capacitor-run single phase AC induction motor control starting circuit is provided which minimizes first cycle current spiking magnitude, and also minimizes cycle to cycle current spiking magnitude, without a choke or inductor in the loop containing the run capacitor, start capacitor and start switch. The first cycle current spiking problem is solved by controlling when the start switch may be turned on at initiation of the starting mode in relation to the AC cycle, to permit turn-on of the start switch only within a known or predictable range of voltage differential between the run and start capacitors. The cycle to cycle current spiking problem is solved by proper phasing of gate current, and supplying gate current to the start switch in phase with the voltage across the run capacitor and out of phase with the current through the series connected start switch and start capacitor.

The process of the invention comprises steps of subjecting at least one of the following component A and component B to contain an alkali metal salt and/or an ammonium salt and mixing the components A and the component B.    Component A:  a solution obtained by dissolving a radical polymerization promotor in a specific polyether base macromonomer.       Component B:  a solution obtained by dissolving a radical polymerization initiator in a specific polyether base oligomer and/or an organic non-aqueous solvent.       To at least one of the component A and component B, a radical polymerization retarder is added, if desired.   The process of the invention can be carried out by a simple step comprised of mixing the two components at room temperature and provides the solid polyelectrolyte having a high inonic conductivity.       The high-ion-condcutive solid polyelectrolyte prepared by the process of the invention is very useful as a raw material for lithium cells, plastic cells, large capacity electrostatic capacitors, electrochromic displays and other overall solidificated systems.

Title: Pre-heating and pre-reduction of metal oxide ore using high temperature off-gases
Inventor: BATTERHAM ROBIN JOHN
IPC: C22B34/30
Filed: 1990-05-30
Abstract: The specification discloses a process for pre-heating and pre-reducing metal oxide ores. The process comprises introducing particles of an oxide ore entrained in a gas through a port into a treatment chamber. Inside the treatment chamber the stream of entrained particles combines with a stream of high temperature reducing gas in such a way that the particles are heated rapidly and enter into flow patterns whereby contact with other particles and the internal surface of the treatment chamber is minimized. The stream of entrained particles and the stream of high temperature reducing gas are substantially co-current. A treatment chamber elongated in the direction of co-current flow is described in the specification. The hot off-gases may be derived from a molten bath reactor and comprise a high concentration of carbon monoxide and hydrogen.

Title: Electrostatic discharge noise suppression method and system for electronic devices
Inventor: PAHR PER O
IPC: H05F3/02
Filed: 1991-07-30
Abstract: Abstract An electrostatic discharge noise suppression method and system is disclosed for electronic devices, particularly those connected to data buses.  Electrostatic discharge protection is provided by breaking high-frequency ground loops by inserting common mode inductors where they can be most effective-in the DC power supplies themselves, in the DC power connections, or just behind the DC connector in the electronic devices.  Saturation of the cores of the common mode inductors is prevented in a preferred way by equalizing supply and return currents in the common mode inductors and by preventing DC ground currents from flowing in a chassis between the power supply and the electronic device.
