Abstract: A gauge strip of flexible material having distal and proximal end portions has a cursor slot in its proximal end portion with graduation marks and penile constriction ring size indicia between the end portions for the distal end of the strip to be passed through the cursor slot to form a loop that is pulled tight on the penis for the cursor slot to coincide with an elastic ring size indicia that is read to select a ring or vacuum tube penis entry opening of the appropriate percentage of the penis size for developing an erection by vacuum exposure, maintaining an erection with the ring, or using the ring as a condom retainer.

Abstract: An inspection machine for transilluminatable bottles inspects the sidewalls of bottles by transmitting a diffused beam of light through the sidewall and using a plurality of mirrors appropriately arranged for detecting or recording the images emergent from the bottle in different directions in the same image recording camera. The arrangement requires at least two separate beam paths and mirrors in each path directing the bottle emergent beams to the camera while the bottles are being conveyed through a position in which they are illuminated. In an improved arrangement, there is a separate cooperating series of beam deflecting mirrors which generate at least three independent beam paths that impinge from different directions on the sidewall of the bottle being inspected. The recording device is preferably a camera having a charge coupled device image plate.

Abstract: A hood preferably made of sheet metal for directing coolant air in air inlet holes in the walls of an avionic box containing electrical components such as an avionic line replaceable unit (LRU). The hood has a top wall with opposite side walls and an end wall that depends unitarily from the top wall. The hood fits onto the box with the top wall and side walls of the hood spaced from the corresponding top wall and side walls, respectively of the avionic box when the hood is mounted on the box to thereby define coolant air conducting passageways contiguous with the box. The end wall of the hood that depends from the top wall is spaced from the end wall of the box when the hood is mounted to the box to define an air distribution plenum that is in communication with the passageways at the sides and top of the box so coolant air is directed through holes in the end wall if any holes are used in the end wall and side walls of the box. The end wall of the hood has an opening for being covered by a door.

Abstract: Systems and methods analyze biopotential morphologies in body tissue. The systems and methods use a template of a biopotential event of known cause in body tissue. The template comprises a plot of variations in biopotentials over time and not a spacial distribution of endocardial surface activation. The systems and methods compare this template to a sample of a biopotential event externally triggered in body tissue. The sample comprises a plot of variations in biopotentials over time and not a spacial distribution of endocardial surface activation. The systems and methods generate an output based upon the comparison. The systems and methods can be used to compare an event-specific template of a cardiac event of known diagnosis to a sample of a paced cardiac event. The comparison yields a matching factor indicating how alike the input sample is to the input template.

Abstract: A roll sign has closed loop belts made up of a series of pivotally connected links for the belts to translate parallel to each other and vertically after passing over driven wheels. Grid members having grooved tracks into which menu strips slide for being lighted from behind to make information on the strips readable. The grid members have similar end portions or webs which contain a keyhole defined by a large hole intersecting a smaller hole. Each link has an attachment pin including a shank whose end is extending through an aperture in the link and a head on the shank that is disposed on a side of the link opposite from the end of the pin. A spring biases the head against the grid member. The large holes of the keyholes fit over the head so that when this is done the grid is shifted laterally against the spring force to have the small holes slide under the head to hold the grid.

Abstract: A wood splitting assembly includes two wood splitting stages mounted on a trailer or truck bed. A first stage for splitting large diameter wood pieces is adapted to be transported in a substantially horizontal orientation to be pivoted to a vertical orientation for use. A horizontal second splitting stage is mounted horizontally. A double stage hydraulic system enables independent reciprocation of the two wood splitting stages independently of each other and is powered by a single motor for driving the hydraulic pump. Preferably a platen at the bottom of the vertical splitting assembly is located a distance from the pivot axis sufficient to engage a level ground surface and thereby to relieve a portion of the weight of the vehicle from a wheel thereof when in a vertical orientation.

Abstract: In a thermal ink transfer machine, the web is drawn translationally through a station at which thermal ink graphics are transferred from the web to the periphery of a container such as a glass or plastic bottle or can. Transfer of the graphics is effected with a transfer head or cylinder which has arranged about its axis of rotation a plurality of equally spaced apart radially spring biased rollers. When the longitudinally extending graphics on the web enters the transfer station, the spring biased rollers yield radially inwardly and outwardly to press against the backside of the web to effect transfer of the graphics. The apparatus has the rotating transfer head on one side of the web and the containers carried on a turntable on the opposite side of the web. The transfer head rotates in a particular direction around its vertical axis and drives the rollers orbitally toward and away from the graphics transfer station.

Abstract: A flowmeter is based on the principle of injecting a pulse of microwave radiation into a flowing stream of material containing a substance having an absorption band for the radiation so as to heat a small quantity of the substance and continue its flow in a conduit to a downstream temperature sensor where the temperature of the quantity is sensed for enabling determination of the time elapsed for the quantity to travel from the point at which the microwave energy is injected to the sensor. A microcontroller receiving signals from the sensor determines when the peak temperature of the quantity is sensed and uses the peak to terminate measurement of a time interval. The time interval starts when the microcontroller senses that the ac sinusoidal power has passed through zero at which time the microwave generator, such as a magnetron, emits a pulse of microwave radiation for heating the quantity of the substance of the material flowing in the conduit.

Abstract: In a rotary switch, a manually rotatable shaft turns a disk which has a plurality of riser cam segments on one of its faces. Stepwise rotation of the disk causes the cam segments to press down on flat spring contacts arranged in the switch to put the tip of one of the contacts at a time into contact with a stationary electrical contact bar that is coated with a noble metal. The spring contacts are configured such that when pressed by a cam the tips are caused to make contact with the stationary contact bar and then slide longitudinally so as the tip will pick up some of the noble metal coating from the contact bar. The tips are shaped with a traverse curve intersecting a longitudinal groove to thereby produce two points that make high unit stress contact with the stationary contact bar.

Abstract: In a rotary switch, a manually rotatable shaft turns a disk which has a plurality of riser cam segments on one of its face. Stepwise rotation of the disk causes the cam segments to press down on flat spring contacts arranged in the switch to put the tip of one of the contacts at a time into electric contact with a stationary electrical contact that is connected to a source of electric potential or, in the alternative, to relieve one of the contacts from being pressed onto the stationary contact. An index wheel mounts to the shaft and has equiangularly spaced grooves. A plastic spring having parallel legs is mounted on the base of the switch. The legs have convex detents which register in successive grooves as the rotor is indexed rotationally in a stepwise fashion. The radius of the detents is greater than the radius of the grooves between the teeth of the index wheel. The legs of the spring are prohibited from moving longitudinally and tension is maintained in the spring legs at all times.

Abstract: Systems and methods examine heart tissue morphology using a pair of electrodes, at least one of which is located in contact with heart tissue. The systems and methods transmit electrical current in a path through the contacted heart tissue between the pair of the electrodes to derive a tissue electrical characteristic based, at least in part, upon sensing the impedance of the tissue lying in the path. The system and methods also sense with at least one of the electrodes the timing of local depolarization events in the contacted heart tissue. The systems and methods make possible the use of multiple endocardial electrodes for taking multiple measurements of the electrical characteristics of heart tissue. Multiplexing can be used to facilitate data processing. The systems and methods also make possible the identification of regions of low relative electrical characteristics, indicative of infarcted tissue, without invasive surgical techniques.
