  • Patent number: 5321391
    Abstract: A fish-bite indicator has a rotary part which is engaged by a fishing line when the indicator is in use, such that longitudinal movement of the fishing line causes the rotary part to rotate. Sensor means are provided to produce a signal for every rotation or part rotation of the rotary part. A counter is connected to the sensor means and constructed to issue an indicator signal in dependence upon each signal or each given count of signals it receives from the sensor means, the counter being constructed so that the number of each given count is alterable. A manually adjustable member is connected to the counter to enable that count to be altered thereby to enable the sensitivity of the indicator to be varied. The invention also extends to a fish-bite indicator comprising a housing having wall means which define (a) a sealed interior of the housing and (b) an enclosure immediately adjacent to the sealed interior.

  • Patent number: 5291331
    Abstract: A light confining cavity collects much of the radiation reflected by a receiver, absorbing it imperfectly, and casts it again on the same receiver or on other receivers by means of an optical system. Only light in a bundle of rays of limited angular spread can escape from this cavity, which allows an entry aperture relatively large. Thus, the irradiance at the entry aperture may be low, and in some cases even lower than the irradiance at the absorber. In this way the requirements for the cavity materials and for the concentrating system feeding light to the cavity can be relaxed. The invention is of special interest in photovoltaic conversion devices because it improves the absorption of the solar cells and achieves higher conversion efficiency for photons of different energies by using solar cells of different materials.

  • Patent number: 5290237
    Abstract: A device for reducing the amount of a gas contained in a liquid includes a central core with an inlet channel, an outlet channel, and a transverse channel. A first chamber is formed on a first side of the core for receiving the liquid from the inlet channel, and a second chamber is formed on the opposite side of the core for receiving the liquid after it has passed through the first chamber. Each of the chambers includes a hydrophobic membrane for allowing gas that has separated from the liquid to pass to the atmosphere. The two chambers are arranged such that gas escaping from the liquid rises to the top of at least one of the chambers for any orientation of the device. The device, accordingly, is not dependent on orientation for effectiveness.

  • Patent number: 5290511
    Abstract: A process, system and pressure chamber for the automated sterilization of articles, particularly medical or dental instruments is disclosed, which is simple to use and economically efficient by comparison with conventional autoclaves and steam sterilizing system. Steam is generated by the pulsed injection of a controlled quantity of water into a heated boiler whenever it runs dry. The boiler is coupled in a closed-loop system to a relatively small pressure chamber in the form of a cassette that is readily inserted and removed from a holder comprising means for connecting the chamber to a steam inlet conduit and a venting conduit, the latter being closed off during pressurization of the chamber. By automated monitoring of the boiler and chamber temperatures, conditions in the chamber are measured and the boiler and valves in the system controlled to effect a sterilization cycle.

  • Patent number: 5291102
    Abstract: A Dynamic Color Separation (DCS) color display system employs signals which provide timing, luminance, and chrominance information of the display output. The display system includes a timing circuit which produces unique signals for correcting errors produced when hue is controlled by the phase of the (S) signal and the degree of saturation with its amplitude. The signals may be applied to known CRT beam guns, and modified guns specific to the generated signals are also disclosed.

  • Patent number: 5269026
    Abstract: A hat of the type having an adjustable headband is provided with a safety liner which includes a lower edge received in the headband. The safety liner has adjustment means for allowing the length of the lower edge to be reduced in response to a circumferentially applied force of the headband. The safety liner includes cut-out sections and is designed to only partially encircle the head of a wearer. A large cutout is provided for location at the rear of the head of a wearer.

  • Patent number: 5245935
    Abstract: Equipment for melting a used injection needle includes a pair of movable contacts (2) and a fixed contact (3) between which electric voltage is applied. A short-circuit detector (4), determines when the movable contacts (2) and the fixed contact (3) are short-circuited by a used injection needle (9), and a timer (5) produces a signal during the period in which the short-circuit detector (4) produces a signal. An electromagnet drives the movable contacts (2) together to secure the used injection needle (9) to decrease the contact resistance between the movable contacts (2) and the used injection needle (9) and to allow a large electric current to flow in the used injection needle (9) in a stable manner.
