    Abstract: 25,146. Laird, G., and Todd, J. P. Nov. 18. Motors, controlling.-Relates to the operation of motor controllers having a braking position and also separate reversing and controlling drums, the controller being operated by a single lever. The reversing-drum is adapted to be connected to the operating-lever by pins or plungers, so that, when in the 'off' position, it can be moved in either direction, the operating-lever being moved in one direction for 'control' whether the motor is running in the forward or backward direction. Figs. 1 and 2 shows one arrangement, in which the operating- lever 5 is mounted on the controlling- drum shaft 4, and is provided with two plungers 7, 8, either one of which can be depressed, when the switch is in the 'off' position, and caused to engage with a groove 3 in the head 2 of the reversing-drum. The plungers have enlarged heads 9 which are admitted through holes in the top of the controller casing, and the shanks of the plungers can slide in a groove 13 or 14 in the casing when the handle is moved. The plungers are carried by a pivoted lever 15 operated by a push 21. By manipulating the push 21 the handle 19 is moved in the Fame direction for 'control,' although the reversing-drum may be set for forward or backward running. In a modified form, Fig. 4, the reversing-drum 22 is loose on the shaft 4, and is operated from the grooved head or plate 27 by geared quadrants. In another modification, the lever is fitted with two handles, in each of which is a push similar to 21. Each push controls one of the plungers. In the form shown in Fig. 9, one plunger only is used, but is fitted in a sliding carrier 35, which may be moved into the position shown in dotted lines when it is desired to turn the reversing-drum in the opposite direction. In another modification, the carrier is connected to the handle which slides in a groove in the lever. In this arrangement, the plunger is operated by a push in the handle. In all the arrangements, a lost motion is provided for the reversing-drum, so that, after it has been moved, the operating-handle can continue its movement in the same direction without interfering with the reversing-drum.

    Abstract: A device for irradiating blood is provided, the device including a chamber having an elongate configuration defining a hollow interior, the chamber formed of reflective material, a tubular cassette sized and shaped to be received in the interior of the chamber, the tubular cassette having an inside diameter sized and shaped to receive a reflective core having an elongate configuration with an exterior diameter smaller than the interior diameter of the cassette to provide a space for receiving and holding blood stationary, and an array of light-emitting members arranged on the chamber for emitting light of at least one wavelength into the interior of the chamber for irradiating and treating the blood inside the cassette.

    Abstract: Granules of plastics material have grains of an inert mineral such as sand coated thereon to provide a habitat for microorganisms effective in waste water treatment, the granules having a predetermined particle size range, and the grains having a predetermined particle size range and being disposed at a predetermined packing density range on the granules. The particles have an average density of approximately 1.0 g/cc such that a proportion tend to float and a proportion tend to sink in the waste water. The particles arc manufactured by contacting the granules of plastics material with a mixture of grains of the inert mineral and grains of a soluble substance such as salt, at an elevated temperature, to coat the granules with the mixture, and subsequently dissolving the soluble substance grains from the coating to provide the granules coated with the grains of inert mineral in the predetermined packing density range.

    Abstract: A loose particulate material for use in waste water treatment comprises granules of plastics material carrying weighting material so that the granules have an average density of approximately 1.0g/cc. At least a portion of the weighting material is carried within the granules and the surfaces of the granules are provided with concavities to provide a habitat for organisms effective in waste water treatment. The particles are manufactured by incorporating a weighting material into the granules, contacting the granules with grains of a soluble substance at an elevated temperature to coat the granules with the soluble substance grains and subsequently dissolving the soluble substance grains. The weighting material may be sand, the soluble substance may be sodium chloride.
