Abstract: An apparatus and method of implanting hair or hair-like strands in areas of the skin of animate beings, comprising a unique fabricated anchorage piece and a novel process for placing the same in the skin, utilizing a hypodermic needle having a grooved barrel and tip portion. The process or method comprises piercing the skin with the assemblage of needle and anchorage member carried thereby, and then advancing the member by means of a suitable plunger in the needle, such that the member is thrust below the surface of the skin while the needle tip is still inserted. The needle is then withdrawn, whereas the anchorage member remains embedded. Strands of hair or hair-like material tied or otherwise secured to the anchorage member emanate from the puncture in the skin created by the needle, thereby providing an especially natural and pleasing appearance not obtainable with most prior methods and procedures of hair replacement.

Abstract: An instrument for viscoelastic measurement, particularly for breast palpation, uses a sensing transducer head which contains at least two spaced, relatively small area transducers. The transducers can be fixed relative to a glove to be worn by an examiner or can be otherwise supported. The transducers have output leads connected to monitoring circuits which monitor differences in output of the transducers when both are pressed against breast tissue in order to sense thickened areas which may be too small to be sensed by manual palpation. The transducer may be attached to a position monitor so that the transducer head output can be continuously related to the location in space of the transducer head, and the output can be displayed in a suitable display.

Abstract: The venous patency of a human limb is assessed by measuring the venous outflow within a defined time interval after release of a forced blockage of the venous return to the heart and correlating it, where necessary, with the increased venous volume occasioned by the forced blockage. The volume changes and outflow rate are determined from electrical impedance measurements.

Abstract: A pressure is applied by pressure means to a blood vessel from the outside, and gradually reduced, and the pressure resulting from movement of the blood pressure during the pressure reduction is converted by a pressure sensor into an electric signal. The converted output is differentiated twice, and it is detected that a first-polarity pulse, a second-polarity pulse and another first-polarity pulse are generated successively in the differentiated output waveform within a predetermined period of time. The highest blood pressure is obtained with the pressure of the pressure means at the moment of first detection of three such pulses, and the lowest blood pressure is obtained with the pressure of the pressure means when the above detection is no longer achieved. The measured values are recorded in a digital form and, at the same time, the converted output waveform is recorded.

Abstract: An orthopedic table for applying controlled flexion and traction to a patient's body includes a table divided at its mid-region into upper and lower platforms. A patient lying on the table is harnessed at the opposite ends of the table, and pelvic straps on the lower platform secure the patient's pelvic region to the lower platform. The platforms pivot simultaneously to periodically lower the central region of the table and separate the inner edges of the platforms. The support provided by the pelvic straps enables the lowered platforms to periodically force the patient's lower back into flexion in the separation space between the platforms. The remote end of the lower platform is adjustable in elevation to control the pull on the patient's hamstrings which, in turn, controls the amount of flexion exerted on the patient's lower back. The patient's head or arms can be selectively harnessed at the head of the upper platform to place the patient's upper body in traction during lowering of the platforms.

Abstract: A cardiac electrode arrangement is disclosed for use in temporarily pacing the heart of a subject and comprises an electrically-conductive strip surrounded by a layer of biocompatible insulating material, which layer has openings on one face of the strip to permit exposure of a portion thereof for contact with the heart and on the other face removably accommodates and holds the stripped end of a pacer lead in contact with the strip. The electrode may be attached to the heart by clips or a single suture, and the pacer lead can be disconnected from the electrode after use by simply pulling the stripped end from under the insulating layer.

Abstract: The contact device disclosed herein is designed for applying stimulating pulses to cardiac muscle tissue to obtain artificial pacing of the heart. Fibrosis around the stimulating electrode itself is minimized by employing a non-binding, preferably quite flexible electrode to establish the contact and using relatively stiff, prong-like attaching members which are separate and substantially spaced from the stimulating electrode itself.

Abstract: A set of heart stimulator leads including first and second leads is disclosed for respectively stimulating and sensing the atrium and ventricle of a patient's heart. The proximal end of each of the aforementioned first and second leads is associated with a heart pacemaker of the atrial-sensing, ventricular-inhibited (ASVIP) or sequential type, both of which have leads that are attached to the atria and ventricles. It is critical to ensure that the first and second leads associated respectively with the atrium and ventricle of the patient's heart, are not interchanged, which condition could possibly cause arrhythmias and morbidity, and is ensured by configuring the proximal end of each of the first and second leads so that both of these leads may not be inserted into the incorrect openings or bores of the pacemaker at the same time.

Abstract: A pacer for cardiac pacing and condition monitoring in which the electrical characteristics of the pacer are altered upon a temporary or permanent charge in monitored conditions, such as the failures defined in a "loss of capture" or a "failure to sense", in which the timed relationship between the pacer signal generator and the cardiac signal is monitored to indicate detection of failure condition. The monitor acts to provide both increased stimulus to recover capture and to provide warning pulses indicating loss of capture or failure to sense, which are sufficiently discernible upon an electrocardiogram to enable later diagnosis, even after self-correction. An additional means for improving the ability of the pacemaker to "pick up" and amplify spontaneous cardiac signals is provided by redundant signal amplifiers which are checked against each other. These circuits and their ability to detect improper recycling are used to indicate a "sensing failure".

Abstract: A tank cleaning machine which comprises a nozzle manifold having one or more nozzles, that can be fed into and retracted from a tank while rotating or oscillating while cleaning fluid is supplied from a hose so that jet cleaning streams are directed to only those areas inside the tank that require cleaning.

The travel feature of the nozzle manifold also permits the addition of a mechanical scrubber, or scraper with a trip arm to allow removal of sludge as the manifold is removed from the tank.

Abstract: A nozzle for use with a light, portable, miniaturized tire inflator. A resilient insert in the well of the nozzle enables it to be connected directly to the metal thread of a tire valve either by mating the insert with the screw thread or by pushing the insert onto the screw thread. The resilient nature of the insert prevents cross threading of the nozzle with the screw thread. During the inflation of the tire, the inflating gas exerts a force on the insert, thus causing it to compress. Such compression enables the insert to hold the screw thread and to provide a seal during the transference of the inflating gas without requiring any mechanical assistance to maintain proper contact with the valve.

Lift arms pivotably couple the forward frame to a main body of a wheeled vehicle. A sway mechanism is coupled to both lift arms to provide for relative movement of one lift arm with respect to the other such that the harvesting frame can sway from the vertical position in a left or right direction. A tilt mechanism is coupled to the harvesting frame, lift arm, and main body to maintain the frame in its vertical ground position as the lift arms lift the frame off the ground. The tilt mechanism also tilts the frame about an axis transverse to the vehicle axis to a horizontal position such that the sheared end of the tree trunk faces rearwardly.
