Abstract: A catheter device for the control of liquid discharge from the urinary bladder, and its use, is described. The catheter device is an elongated flexible tube of elastic material having an inlet opening at a distal end thereof and one or more inflatable balloons secured about the tube spaced from the inlet opening. The balloon retains the catheter at a predetermined position within the urethra while preventing urine to flow about the catheter below the balloon. The tube is provided with a numbered scale printed in a predetermined proximal end portion of the tube to provide a visual indication to a user person of the length of the catheter inserted in the urethra to permit the positioning of the one or more balloons at a desired location in the urethra below the bladder during repetitive removal and insertion of the catheter.

Abstract: A surgically implantable urethra pressure control valve is described. It comprises a clamp having a pair of spaced-apart clamping arms. A urethra passage is defined between the clamping arms. At least one of the clamping arms is a displaceable clamping arm movable towards the other clamping arm to a predetermined position spaced from the other clamping arm a distance sufficient to pinch and close an inner passage of the urethra when disposed in the urethra passage whereby to arrest the flow of urine. An actuator is provided to effect the displacement of the displaceable clamping arm. The actuator may be a remote control to operate the valve or an implanted sphincter to apply a closing pressure upon the urethra.

Abstract: A metal wire rod shopping cart wherein a reinforced display frame is integrated in a wall of at least one of a front wall, opposed side walls or the backrest wall of a baby seat compartment. The reinforced display frame is a U-shaped metal channel defined by opposed parallel side channel members and an integral transverse end channel member disposed in a common plane. The channel members have longitudinal slots having a slot opening facing inwardly to one another. A metal panel sheet is secured substantially centrally in said slots of at least said opposed parallel side channel members to divide the slots to form an outer and inner slot adjacent an outer and inner side wall of the metal panel sheet whereby to receive a promotional sheet having display material thereon in sliding fit over the outer and inner side walls between opposed parallel ones of the outer and inner slots.

Abstract: An all-terrain bicycle is comprised of a tubular frame defined by a main frame section and a front fork and a pair of rear forks, to which is removably secured a front and a rear wheel. The wheels are formed of plastics material and define a hub, a circular outer molded solid tire, and an intermediate connecting framework. The outer molded solid tire is a one-piece tire defining, when viewed in transverse cross-section, a central projecting dome merging into opposed tapered wings which are recessed from the top of the dome. An integrally molded connecting formation is provided under the dome to secure to a rim of the connecting framework. The dome defines a circumferential central rib around the outer molded tire for the displacement of the bicycle on a hard surface with the wings spaced from the hard surface. The wings constitute a wide tire support surface, together with the central rib, for the displacement of the bicycle on soft surfaces such as sand, grass, etc.

Abstract: A business method and a shopping cart for use with that method is described. The shopping cart has an articles carrying basket which is secured to a frame displaceable on casters by a user person. The basket has a bottom wall, opposed side walls, a front wall, a rear gate assembly and an open top end. The method comprises the steps of providing at least one display frame in a surface of at least one of the front wall and opposed side walls. A promotional sheet having display material thereon is also provided for removable attachment to the at least one display frame. The display material contains an imagery and/or written material of promotional content whereby to increase the sale of a promotional product which is displayed or described on the sheet and for a predetermined period of time. The promotional sheet is changed after the predetermined period of time to provide a further promotion during a further predetermined period of time.

Abstract: An all-terrain bicycle is comprised of a bicycle frame having a front and a rear fork to which is removably secured a front and a rear wheel. Each wheel has a circular rim which is interconnected to the hub by spokes. The rear wheel has sprockets secured to the central hub and which is interconnected to a driving sprocket by a chain or other such belt-like drive connector. Each of the rims is provided with a surface engaging support shoes assembly to provide support of the bicycle on a surface. Such bicycles are particularly useful for riding on soft and also irregular surfaces which are deformable such as sand, snow or the like.

Abstract: A nestable shopping cart is comprised of a main containment basket supported elevated by a frame which is displaceable on casters. A handle bar is secured rearwardly spaced from a rear wall of the basket by spaced side attachment members at opposed ends thereof. A restraining open area is defined between the rear wall of the shopping basket, the handle bar and the space side attachment members. A secondary containment basket is secured between a pair of rear frame members in a lower section of the frame and has at least a portion of a top open end thereof aligned substantially on a vertical axis passing through the restraining open area. The secondary basket is secured spaced inwardly of the pair of rear frame members by nesting support brackets.

Abstract: An end-to-end nestable shopping cart having a frame supported on casters with a basket having an open top end supported elevated by the frame.
