An electrolysis needle having a thin dielectric coating deposited over the entire penetrating tip portion and the lower portion of the shank of the needle and then partially removed adjacent the tip of the needle to prevent electric shock or burning of the epidermis with resultant elimination of pain to the patient.

Endoscope having a bendable tube connected to a forward end member adapted to be inserted into a hollow body portion to be inspected and controlled from a control housing and an elongated flexible tube connecting the bendable tube and the control housing. The flexible tube has a thin tubular synthetic resin layer having a tubular net-like braid of non-metallic fibers embedded therein and another thin tubular synthetic resin layer having a tubular net-like braid of metallic fibers embedded therei...

An alarm reset technique in a sphygmomanometer adapted for automatically monitoring a patient's blood pressure at regular intervals, having electronic detection circuitry responsive to an alarm condition defined by high- and/or low-alarm comparator units and other sphygmomanometer signals to activate an alarm, and electronic logic circuitry for resetting a prior interval activated alarm without inhibiting subsequent activation of the alarm in the interval when reset.

An elongated hand-held surgical instrument for use in intraoral lower jaw defect correcting surgery including an operative end portion for insertion within a surgical wound or incision and having an integral curved tab therein for engaging behind a ramus of a mandible and a retracting portion inwards of said end portion having opposite concave-convex surfaces for retracting the cheek and corner of the mouth during surgery with the concave surface engaging the corner of the mouth.

A sphygmomanometer of the aneroid gauge type having bellows connected through gears to rotate a shaft, and a pointer mounted on the shaft and movable over a dial to indicate pressure, includes recording means manually actuable to temporarily mark the systolic and diastolic pressures. The recording means has a two layer adhesion marking means attached to the dial and a stylus carried by the shaft in registry with the pointer, and movable to impress a mark upon the adhesion marking means. A separa...

An apparatus for measuring the force exerted by a thumb or finger of a test subject, having a hand grip with a thumb pressure well being positioned on a beam adjacent the hand grip. The beam has a reduced section with strain gages thereon, with the output of the strain gages being applied to a recording device. Adjustments are provided to adjust the relative angular and vertical positions of the thumb pressure well with respect to the hand grip.

A method by which physical and mechanical characteristics of rocks are measured during drilling, comprises picking up a signal representing the vibrations of a train of rods forming part of drilling gear, selecting the components of the said signal which, after peak-clipping, are in a frequency band which is centered on, and preferably is related to, a characteristic frequency of the tool, establishing from the components thus selected, a value which is representative of the amplitude of the vib...

An apparatus which serves for the care of the body and which consists of a protective plate provided with an elongated handle, a cover plate and a cutting blade. The protective plate includes two planing holes and two slits, one extending transversely to the longitudinal axis and the other extending on the longitudinal axis of the apparatus. Each slit possesses at least one exposed tongue. The cover plate is provided with a bent-up tab which has at least one slit to enable it to be locked to the...

A leveling mechanism comprising two eccentrics rotatably mounted around the mounting shaft of a suspension system that supports an X-ray head. Respective wrenches for such eccentrics are mounted to the suspension system and may cooperatively engage their respective eccentrics to facilitate leveling of the suspension system in order to prevent drifting of the X-ray head.

A device which is to be used with a tonometer for facilitating the operation thereof. The device includes a pair of retractors for respectively retracting the upper and lower eyelids of an eye which is to be examined. A holding unit holds and carries the pair of retractors in a position where they conveniently pull the eyelids apart from each other with a regulated force. A supporting device is provided for supporting a tonometer in a convenient position of operation while the eyelids are held b...
