The housing includes a fastener feeding mechanism for feeding fasteners one at a time into the hollow needle. The fastners used with the apparatus each include a bar portion and a head portion which are connected by an elongated filament portion. A plunger mechanism is provided for driving the fasteners through the needle. The plunger mechanism is operated by an electric motor which is connected to a pair of rechargeable batteries mounted in the handle portion of the housing. A recharger circuit is also mounted in the handle of the housing for periodic recharging of the batteries.

Abstract: A solenoid control valve includes a solenoid housing which encloses a solenoid and an armature which is actuated by the solinoid in order to control the flow of fluid through the valve. contact spring makes continuous electrical contact with the armature and the armature is electrically insulated from the valve except when the solenoid brings the armature into contact with a stop portion which is integrally formed in the body of the valve. Contact between the armature and the stop completes an electrical circuit between the spring contact, the armature and the valve body, thereby providing a precise electrical indication of the mechanical state of the valve without any degradation due to hysteresis or mechanical losses.

Abstract: A device is provided for controlling flow and pressure of a gas for insufflating the abdomen during laparoscopic surgery. Compressed gas from a tank passes through the device and is stepped down through multiple stages to a pressure under 25 psi. The resultant average pressure is then reduced to a desired pressure by passing the gas through a solenoid valve and manifold in a pulsating manner. Pressure and flow are constantly monitored with signals being sent to a microprocessor which adjusts the pulse width of the gas supply to compensate for any changes in pressure.

Abstract: An electro-surgical instrument and method is described for exposing gingival areas in preparation for a dental implant. The instrument includes an elongated handle, a leg extending perpendicular to the handle adjoined therewith, and a circular cutting loop. The loop is defined by a plane perpendicular to the leg and tangentially attached thereto along a circumference of the loop. The loop is formed of a unitary electrically conductive wire such as tungsten, and extends into the leg and at least partially into the handle. A high frequency current is passed through the wire into the loop to best activate the latter for cutting the gingival areas.

Abstract: A cam is eccentrically journaled at one end of a compound archery bow and a pulley is journaled at the other end of the bow. A cable passes around the pulley to form a bowstring section and a second cable section, both sections forming a dual feed single cam compound bow. The amount of feed out to both ends of the bowstring is approximately the same. One embodiment of the cam provides a large radius cam groove and a smaller radius cam groove which are designed to synchronize the rate of cable feed out at both ends of the bowstring section during the drawing operation. An anchor cable is provided to tie the two limbs of the bow together during the flexing of the bow.

Abstract: A folding table is described with a tablet and supporting frame. The frame includes an outer and inner pair of legs as well as a U-shaped link bar. The outer legs are directly attached by a connector to the underside of the tablet. The inner legs are pivotally joined to the outer ones and further are pivotally joined to the U-shaped link bar. In turn, free ends of the link bar are pivotally attached to the underside of the tablet through an L-shaped bracket. A stop device in the form of a brace with leg extending orthogonally outward is attached onto the link bar to brace the latter against the inner legs when the table is in the open upright position. Each of the legs have upper and lower portions, these portions being bent at an obtuse angle relative to one another. When the table is completely folded, the upper portions of the legs are oriented parallel to one another while the lower ones are oriented away from one another.

Abstract: A strong, lightweight metal handle for a compound bow. The bow handle may be machined from a bar of stock metal such as aluminum or an alloy thereof. The handle is formed with one or more recesses or one or more recesses can be thereafter machined out of the handle. The recess or recesses extend from the side of the handle under compression when the compound bow is drawn and extend toward the side of the handle which is under tension when the bow is drawn.

The article includes a folder for the sheets and a storage pocket for the computer disc. The storage pocket will be of smaller dimension than the folder and attached to a front surface of the folder. The pocket will have a rear wall, front wall and cover flap, the latter preferably being formed unitarily with the rear wall. A plastic strip attached across an open mouth of the pocket serves as a latching device for retaining the flap in a covering position over the mouth. Preferably the entire article will be of a transparent plastic so as to allow viewing of any contents within either the folder or pocket.

Abstract: A method and device is described for removing concretions such as calculus stones within human ducts such as the ureter or kidney. The device includes a flexible probe insertable through the human duct so that a tip thereof is juxtaposed against the concretion. The probe includes a positive electrode extending coaxially within the conduit and embedded in a solid electrically insulative material. A negative electrode is coextensive with and outwardly encircles the positive electrode. The solid electrically insulative material stops short by a distance R from the end of the probe, thereby leaving a recess without solid insulation between negative and positive electrodes at the tip end of the probe. The recess achieves a more efficient fragmentation of target calculi at lower energy, with less human tissue damage and increase in useful probe life.

Abstract: A special host routing code is transmitted from the remote switch to a host switch which advises the host switch whether the call is to be made to a subscriber local to the host switch or to a remote subscriber via an external telephone system trunk connected to the host switch. In the set up of a call, two steps are executed in addition to those of a normal switch-to-switch communication which functions to set up a path from the remote switch through, or to the host switch. These steps are the outpulsing of a host routing code from the remote switch over a specified trunk to the host switch and waiting for an acknowledgement, such as a wink (temporary line open or close condition). This causes the host switch to set up a cut-through path through the host switch, allowing the remote switch to tandem through the host switch. The digits dialed by subscribers on both switches to affect similar types of calls are therefore similar, and similar types of switches can be used for the remote and host switches.
