Abstract: A suture package is provided comprising an outer sealed package and an inner sterile suture containing package. The inner suture containing package comprises pairs of heat sealed plastic sheets which form a series of pockets which are open at one end. Each of these pockets is adapted to contain a pre-reeled suture disposed within an envelope. Two rows of pockets are sealed together so as to be offset both laterally and vertically to provide a pair of rows of suture containing pockets which are offset with respect to each other for easy access. A portion of the suture within each envelope extends outwardly of the end of the envelope so that the suture may be grasped and withdrawn from the envelope.
Abstract: A whistling teakettle with an attached food boiling device is disclosed which is especially suitable for soft-boiling eggs and the like. Both the teakettle and the boiling device are designed to be exposed to a burner surface. However, due to the decreased volume of water in the boiling device, this water boils sooner than the water in the teakettle. Thus, a food, such as eggs, placed in the boiling device is cooked during the same time that water in the teakettle reaches a boil and causes the teakettle to "whistle". By measuring the volume of water in the teakettle, the "whistle" of the teakettle is used as a timed alarm for the cooking of the eggs.
Abstract: Disclosed is an electrically operated condensate drain valve arrangement for draining condensate from a fluid transfer system, the arrangement comprising a condensate drain valve (3), an electronic circuit (5 or 21) for controlling operation of the valve, and at least one sensing element (1 or 19 and 20) for insertion in the fluid transfer system to trigger the electronic circuit for operating the valve when a predetermined condition in the system is sensed by the sensing element; the electronic circuit including a delay means (10) imparting a desired minimum period between successive particular operations of the valve. In one use the predetermined condition is that condensate level is below the sensing element and the circuit is triggered to close the valve when this condition is sensed.

Abstract: Apparatus for transfer of toxic and radioactive materials between a work enclosure and a container for storing and transporting the materials. Materials are moved through a "double-cover" in which a port in the enclosure is closed by a first cover and the container is closed by a second cover. During transfer, the covers are connected together and the space between the covers is swept by an air stream to prevent ingress and deposition of toxic or radioactive material on the surfaces thereof which are exposed to the environment on separation of the covers.
Abstract: A method of determining the volume flow of a fluid through a conduit usable with a single crystal, whereby at least one of the fluid and the conduit have energy-scattering interfaces. The method in one embodiment includes transmitting a known, uniform sound field through the fluid which illuminates the entire cross-sectional area of the conduit, obtaining the Doppler signal from the received signal such that the sampling region is normal to the direction of propagation of the sound field; and obtaining the integral of the power over this surface. A known volume of fluid totally within the conduit is then sampled for the reference power return therefrom and this reference power return is divided into the first moment of the power to produce a signal proportional to the volume flow of the fluid through the conduit.

Abstract: An electrode, connected to a fence charger or the like is secured across the bottom of a gate, fence or the like. A shield partially surrounds the electrode to prevent animals from contacting the electrode unless the animals attempt to put their heads under the gate or fence or attempt to crawl under the gate or fence.
Abstract: The invention provides improved stator windings for pole-amplitude modulation (P.A.M.) pole-changing electric motors and generators. In large machine of high pole-numbers, the effect of adjacent harmonics of m.m.f. waveform becomes evident in the form of low-frequency vibration of the frame. In small machines the effect, although present, is less important. The invention provides stator windings, particularly for large machines, wherein the phase-winding coil grouping, selected primarily for sinusoidal modulation, is selected secondarily to include a third-harmonic content, whereby the adjacent harmonic m.m.f. content may be reduced for both alternative pole-numbers.

Abstract: A sealing device for minimizing the leakage of toxic or radioactive contaminated environments through a biological shield along an opening through which a flexible component moves that penetrates the shield. The sealing device comprises an outer tubular member which extends over a length not less than the maximum longitudinal movement of the component along the opening. An inner sealing block is located intermediate the length of the component and is positioned in the bore of the outer tubular member to slide in the bore and effect a seal over the entire longitudinal movement of the component.
Abstract: A monolithic Darlington in which the transistors forming the Darlington pair are formed on a substrate together with a fourth terminal in addition to the normal three terminals provided for a Darlington pair, the fourth terminal being connected to the base electrode of the second transistor and the emitter electrode of the first transistor. The addition of the fourth terminal enables a control circuit for controlling the rate of switch off to be connected between the fourth terminal and the command collector electrode, this removing the effect which the stored charge on the base electrode of the first transistor has on the switching rate of the Darlington pair, thus enabling a faster switching rate to be achieved.
Abstract: An arrangement for storing cryogenic liquid comprises a Dewar-flask-like vessel. The vessel is filled completely with a material able to absorb a cryogenic substance when said substance is in liquid form but only capable of absorbing said substance to a limited extent when said substance is in gas form. Adjacent to the mouth of said vessel and externally thereof there is provided a cavity, which is arranged to cooperate with means by which any gases formed in said cavity can be released to atmosphere when the pressure in said cavity exceeds a given pressure.
Abstract: Process and apparatus for measurement of brightness of milled products, especially flour, are disclosed. The process is of the general type in which the surface of a layer of flour is illuminated, and the returned quantity of light is taken to an optical electrical transducer. A light source is used for illumination, and the light beam is optically decomposed into at least two part-beams (reference beam and measurement beam) for transmission to the transducer. At least one of the part-beams is cyclicly interrupted or broken into two essentially time-shifted measurement phases in such a way that of the two part-beams, only one of the two-part beams will strike the transducer during a first measurement phase, and during a second measurement phase at least the other part-beam will be applied to the transducer.
