Patent CA-1161119-A (CA)
Inventor: TAPPER ROBERT
IPC: A61N1/18

Abstract: ABSTRACT          This invention relates to a method and apparatus for effecting an electrotherapeutic treatment on a living body, and more particularly, to the application of an iontophoretic treatment topically to the skin of a human body.  Prior art iontophoretic treatments are known to be accompanied by undesirable effects such as the occurrence of burns in the treated area as well as the formation of undesirable vesicles and bulla, and redness of the skin in the treated area.  The present invention provides a method and apparatus for applying an iontophoretic treatment which includes conducting direct current through the skin of the body, and periodically reversing the current and conducting a relatively short pulse of current through the skin in the opposite direction.  It has been discovered that by intermittently including relatively short pulses of current in a direction opposite the direction of the normal direct current treatment, the undesirable formation of vesicles, bulla and reddening of the skin in the treated area is greatly reduced or even eliminated.

Abstract: ABSTRACT OF THE DISCLOSURE        This invention relates to a novel reinforcing bar for a suspension file folder assembly, a novel index tab adapted therefore and a new glide insert for use therewith.          The reinforcing bar comprises an elongated bar with depending legs which embrace the top portion of the folder and has a reinforcing rib formed therein.  The bottom edge of one of the legs has at least one indexing notch cut therefrom.  The index tab is adapted to fit on the top of the bar and engages the reinforcing bar (and the notches) to provide a positive lock thereto, but may be adjusted easily and simply to any desired position on the bar.  The tab has a top loading feature which provides a further improvement over the prior art.  The bar has a glide insert at each terminal end which allows for easy and free movement of the bar along rails which support the file folders with a substantial reduction of noise and friction when the bars are moved along the rails in filing cabinets, drawers, stands or the like.

Abstract: ABSTRACT OF THE DISCLOSURE 1-Aryl-2-(1H-imidazol-1-yl)-ethanone oxime others are known to exist as a mixture of isomers corresponding to the formulas:                                       (It)   and           (Ic) transm- isomer                  cis- isomer To prepare such an isomer in a stereospecifically pure form, the stereoisomer of the corresponding ethanone oxima is first converted into an alkali salt in a polar solvent, such as acetone or dimethylformamide, and the converted to the desired ether by reaction it at a temperature not higher than 40°C with a halogen compound capable of forming the desired ether.  Isolation of the ether product is obtained by precipitating it as an acid addition salt upon addition of a suitable organic or mineral acid, e/g/. aqueous acetic, hydrochloric, sulfuric or, most preferably, nitric acid.  A stereospecific ethanone oxime in either its trans- or cis-isomer form corresponding to the formula:                               or (It)               (Ic) transm- isomer                  cis- isomer can be stereospecifically synthesized from the corresponding 2-halogen ethanone having the formula A-CO-CH2-Hal (IV) which, in making the cis oxime (IIc), is first converted with imidazole or a suitably substituted derivative thereof and subsequently oximated by reaction with hydroxylamine at an elevated temperature; or which, in preparing the trans oxime (IIc), is first oximated by reaction with hydroxyl-amine under mild conditions and subsequently converted in the cold with imidazole or a suitably substituted derivative thereof.  She products are effective fungicides or bacteri-cides and consequently useful as chemotherapeutic agents in combatting undesirable lower plant organisms in the fields of human as well as veterinary medicine and also as fungi-cides in agriculture and horticulture.

Abstract: ABSTRACT OF THE DISCLOSURE     An apparatus is disclosed for separating particles in a flowable medium.  In the past rotors of such devices have been provided with a central shaft supported in an opening in a housing and driven by an exterior motor.  Thus expensive bearings and seals are normally required to assure proper shaft alignment.  In the present device a rotor is rotatably mounted in a housing, the rotor comprising two face rings spaced apart in the axial direction of the rotor and a plurality of blades extending axially therebetween.          The face rings are supported for rotation about their outer circumferences in the housing with at least one of the rings being driven.  An inlet and an outlet are provided in the housing for a flowable medium which is drawn through the flow machine so that it flows axially through the rotor and traverses the blades substantially radially as it flows between the inlet and the outlet effecting a separation of particles in the flowable medium.

Abstract: CRUSTACEAN SHELLING APPARATUS     Abstract of the Invention A crustacean shelling apparatus includes a cupped wheel feed assembly positioned transversely adjacent and centered on a pair of counterro-tating vertically mounted squeeze rollers. The cupped wheel feed assembly includes a plurality of outwardly opening cups spaced circumferentially around the outer rim of the wheel assembly. Crustacean body parts are manually placed into the cups as they rotate through an upwardly opening position near the top of the wheel assembly, wherefrom they are carried to a position immediately adjacent the nip of the counterrotating rollers. A pressurized water feed mechanism positioned slidably abutting the inside surface of the outer rim of the feed wheel assembly thereupon comes into registry with an aperture at the bottom of each cup as the cup approaches the rollers and drives the crustacean body parts into the nip of the rollers by means of a stream of water. The crustacean body part is separated into a meat portion and a shell portion upon being grasped in the nip of the counterrotating rollers. The meat portion falls directly into a meat chute without passing through the rollers. The separated shell portion passes through the rollers and falls into a shell chute.
