Abstract: A tubular measuring chamber (3) is described for temporarily holding alveolar breath for determining the quantity of alcohol in the breath of infra red radiation absorption. The radiation path length between an I.R. source (1, 2) and a condenser lens (7) and detector (8) is made a multiple of the actual length of the tube by bending the tube in any convenient way e.g. a helix (FIG. 1 and FIG. 3), a serpentine (FIG. 2), or meanderingly with definite bends (FIGS. 4-7).The internal surface of the tube (3) is made highly reflective to I.R. and plane reflectors (10) are located at definite bends in the tube or between different sections of tube (see FIGS. 4-7), to deflect radiation from one tube section to the next.A saliva trap and mouthpiece (6) to receive the breath is connected mid-way along the tube (3) between the radiation source (1, 2) and condenser (7).

Abstract: A device for measuring concentration of a gas adapted to be used for measuring the concentration of alcohol molecules in exhaled breath. The device relies for its operation on the known phenomenon that radiation is absorbed by different materials at different characteristic wavelengths. Radiation of a wavelength which will be absorbed by the gas to be tested is focused into the end of a tube the internal surface of which is highly polished or formed with a layer of material which is totally internally reflecting at the wavelength used and a radiation detector is located at the opposite end of the tube.Partly to increase the path length by causing many internal reflections to occur and partly to reduce the overall size of the device, the tube is curved either in the form of a helix with constant or varying radius of curvature or is curved first one and then the next in a serpentine fashion.

Abstract: An adapter for mounting in wallboard-type or other planar ceilings so as to permit the utilization of light fixtures which hitherto could only be used in inverted tee-bar types of suspended ceilings. The adapter includes a plurality of frame members, one for each edge of a ceiling opening, each frame member being configured to have a flange for abutting against the lower ceiling surface and a shoulder thereabove. Corner members for each corner of the adapter have a planar wall and a flange extending from the lower edge thereof. The corner members are transversely adjustable relative to the frame members. In use the ceiling panel is clamped between the flanges of the corner members and those of the frame members and the light fixture is positioned in the opening so that the peripheral lower edge of the fixture rests on the shoulders of the frame members.

Abstract: The described apparatus has utility as a doctor on a paper machine, as a drying element in an aircap dryer and as a sealing element in such a dryer. It involves a foot portion having an outer surface generally conforming to the curvature of the cylinder surface on which it is used. It is resiliently supported in close juxtaposition to the cylinder surface so that a gap diminishing in thickness towards one longitudinal edge of the foot portion is provided. At least two rows of nozzles communicate through the foot portion in order to project pressurized air into the gap. Each nozzle is angled relative to three orthogonal planes, one of which is tangent to the cylinder surface at the point where the nozzle axis meets the surface, another of which is parallel to the longitudinal edge of the foot portion. The flow from the nozzles is such as to support the foot portion and to seal the support flow from any disorganized flows.

Abstract: A mold, such as a hamburger patty press, is of single piece molded plastic construction. The top wall of the mold has a U-shaped slot and grooves extending from the ends of the slot to the adjacent edges of the wall to form integral hinges permitting a portion of the mold to be swung upwardly.

Abstract: A rotary viscometer is described in which the force measuring device for measuring the force acting on a measuring surface, normal to the surface thereof, is contained within a separate housing releasably connected to the remainder of the apparatus.The force measuring device comprises a beam and the force is communicated to the beam by an intermediate thrust member which is stiff and does not yield to axial loads but will move readily to other directions to accommodate misalignment.

Abstract: There is disclosed a vibrator equipped with a hollow motive shaft penetrating through a rotor of an electric motor to project front and rear of the motor and a vibrating shaft arranged in the hollow portion of the motive shaft in concentric and rotatable relations to rotate in the same direction as the motive shaft at a higher speed than the same through a rotation transmission mechanism interposed between said two shafts.

Abstract: A device as described whereby the concentration of a gas such as alcohol vapor can be measured using radiation absorption techniques in a chamber. The chamber is an elongated tube having a window at one end through which infra red radiation can pass with an optical reflector at the two ends of the tube and at least one other reflector for causing the reflected radiation to leave the tube through a second window in the side of the tube, from where it passes to a detector.Sensitivity is increased by passing the radiation in series through a number of parallel arranged chambers which conveniently are located within a common housing.

Abstract: A refuse compacting mechanism is provided in the container of a refuse wagon. The mechanism includes a series of bars transversely oriented on the floor of the container and a pusher mechanism at the rear of the container. Uncompacted refuse falls into the container rearwardly of the bars and is pushed toward and compacted against the rearmost bar by the pusher mechanism. As additional refuse is added and compacted, the previously compacted mass topples forwardly over the rearmost bar to be further compacted against the next bar. Preferrably, the bars are connected to endless chains and may be moved rearwardly in unison to aid in unloading compacted refuse from the container.

Abstract: A fence which provides an effective barrier to the attempts of children to climb and which is of durable and attractive appearance is formed of molded or stamped panels connected to support posts and a fence cap interlocking with the upper ends of the panels. Openings to reduce wind loading on the fence are provided in the panels and are configured so as not to provide hand or foot holds for children. A self-closing gate with a child-resistant latch is also provided.

Abstract: A vibrating feeder for feeding disc-like objects such as coins to a subsequent work station such as a coin sorter has a unitary box-like structure provided with a particularly contoured bottom. The bottom defines a main flow path and an auxiliary flow path leading to the main flow path which in turn terminates in an exit for the coins. The auxiliary flow path has longitudinally inclined fins for guiding coins to the main flow path while somewhat retarding the flow rate to avoid jamming of coins and to avoid an excessive flow rate. Each flow path also includes one or more troughs contoured so that a coin will not lie flat thereon. The feeder is inexpensive to produce, is simple in execution and operation and provides a controlled flow rate for coins or other objects to the subsequent work station.
