Abstract: ABSTRACT           In a compact thermal flowmeter unit of the type wherein a portion of the fluid in a main flow path is shunted through a laminar-flow sensor passageway, that section of the main flow path which the sensor bypasses is occupied by an appropriate range-governing cartridge selected from among a family of externally-similar tubular flow-regulating cartridges each having a different flow capacity as determined by the totals of cross-sectional areas of its plurality of linear flow channels each exhibiting an ef-fective ratio of length to cross-section which promotes laminar flow but is nevertheless advantageously relatively short.  Such tubular cartridges are conveniently inserted into and removed from threaded fastening within the unit by way of one end thereof where there is an accomodating removable end fitting; not only may changes in measurement ranges be effected readily by substituting different cartridges, but the cartridges may also be removed, easily purged clean of possible contaminants and obstructions, and replaced simply and with little effort, skill or delay.  Although each intricate cartridge is essentially a precision element, its critical multiple laminar-flow channels are uniquely produced conveniently and economically with the aid of a few common uniform-diameter wires extending linearly in a special press-fit relationship between a tubular casing and a coaxial core member.

Abstract: FILE HOLE PUNCH RING APPARATUS FOR WEB FED PAPER CONVEYING MECHANISM          Abstract of the Disclosure A punch ring apparatus particularly useful in a printing operating involving web fed paper is provided which is easily adapted for punching file holes, line holes, or a wide variety of hole patterns in the moving paper web, thereby substantially reduc-ing makeready times and associated costs.  The punch ring hereof preferably includes a plurality of radi-ally-oriented,  spaced-apart punches mounted  in the punch ring and radially shiftable between an outer-most punch position and a retracted position, with the punches being spring biased into the retracted position.  The punch ring preferably includes an annular concentric groove in an axial face thereof, with the proximal ends of the punches extending into the groove when the punches are in the retracted position.  One or more annular camming rings are received in the groove and configured such that axial rotation of a camming ring will outwardly shift one or more of the punches into the punch position to produce the desired hole punch pattern.  Complement-ally, the die ring of the present invention is con-figured for operation with any of the hole punch patterns selectable on the punch ring.  Thus, the operator can quickly and easily reconfigure the punch ring apparatus hereof for a different hole punch pattern in a minimum amount of makeready time.

Abstract: DISPENSING CAP CONSTRUCTION                     ABSTRACT      A cam-advance, thread-retract dispensing stopper cap construction of unusually short axial dimension, comprising a body portion having annular walls with a discharge passage extending through it, and a captive screw cap movable axially on the body portion between sealing and dispensing positions. Both the screw cap and the body portion have cooperable screw threads which are operable in a screwing-down direction only. The body portion has a stopper plug which is carried in the dis-charge passage by means of multiple webs, and which is adapted to be received in a discharge orifice of the screw cap when the latter is disposed in the sealing or fully screwed-down position. An annular space is defined between the walls of the body portion and the stopper plug, and contains a curved cam track on which a depend-ing cam follower lug of the screw cap can ride as the latter is unscrewed, thereby to positively force the cap open. The arrangement is such that in the fully unscrewed condition, the discharge orifice of the screw cap is raised above the stopper plug a sufficient amount to permit the contents of the container to be dispensed therethrough. The advantage of the present construction over the devices of the prior art is that due to the unique, arrangement of the cooperable threads and of the cam track and follower construction, an extremely com-pact closure is realizeable with only a minimum amount of axial length being required. This is important in certain applications, as where it is necessary to limit the overall axial length of the container, or where a reduced-length closure is desired for aesthetic reasons.

Abstract: Abstract of the Disclosure A synthetic resin wound dressing (e.g., a burn wound dressing) is disclosed consisting essentially of a polymer, such as poly(2-hydroxyethylmethacrylate), referred to as PHEMA, an organic solvent, such as polyethylene glycol (PEG), and a hydrogen binding plasticizer, such as dimethylsulfoxide (DMSO).  The plasticizer regulates the set-up time of the synthetic resin so that the more plasticizer present, the shorter the set-up time.  The dressing may be applied to the wound site in the form of a paste for the in situ curing or setting thereof, or the dressing may be preformed and then applied to the wound site.  A variety of drug agents (e.g., silver sulfadiazine) may be incorporated in the synthetic resin so as to result in the time released administration of the drug agent to the area of the skin (e.g., a burn wound site or the like) covered by the wound dressing.  A method of treatment using this dressing is also disclosed.

A tachometer is operatively connected to the vehicle wheel and responsive to vehicle wheel rotation for generating an electrical speed signal indicative of the rotational speed of the vehicle wheel. A threshold device is operatively coupled to the tachometer and responsive to vehicle wheel rotation for generating an electrical excessive rate signal indicative of occurrences of an excessive rate of change in changing rotational speeds of the vehicle wheel.  There is a reference device electrically connected with the threshold device and tachometer for receiving electrical signals there-from and for generating a changing electrical reference signal indicative of an acceptable rate of change in changing rotational speeds of the vehicle wheel.  A device is opera-tively associated with the vehicle for responding to varia-tions in vehicle operating conditions and with said reference device for varying the rate of change of the reference signal in predetermined relation to variations in vehicle operating conditions.  A comparator device is electrically connected with the tachometer and reference device for receiving electrical signals therefrom and for comparing the speed and reference signals and for generating a logic signal indicative of the relation of the speed and reference signals.  An electrical switching device is electrically connected with the threshold device and comparator device for receiving electrical signals there-from and for generating an electrical output signal for transmission to the braking force modulator and indicative of a brake relief phase of modulation of braking force.
