A horizontal stepper apparatus including a pair of pedal assemblies connected to a pair of cable and pulley assemblies may be used to simultaneously exercise the arms and legs of a user, with resistence force being provided by a hydraulic cylinder. The apparatus may alternatively be utilized to separately exercise the arms by rotating a seat 180.degree..

In a horizontal deflection system, an nf.sub.H timing signal is generated synchronously with an f.sub.H horizontal synchronizing component in a video signal, where nf.sub.H is a higher frequency than f.sub.H. A first circuit is responsive to the nf.sub.H timing signal for generating an nf.sub.H scan synchronizing signal synchronously with the nfH timing signal. A horizontal deflection stage is operable at nf.sub.H and responsive to the nf.sub.H scan synchronizing signal. A second circuit is resp...

A horizontal fermenter which allows the uninhibited growth of an organism is disclosed. The fermenter is particularly useful for producing alcohols such as ethanol from sugars such as glucose, and comprises a container for holding a selected nutrient solution. A fiber or wood substrate is included for supporting a selected organism such as Zymomonas. Also included is means for physically detaching or dislodging the organisms from the substrate.

This invention relates to a power-driven conveyor system for transporting and accumulating a plurality of items along a path of movement from a source to a destination. The system includes a horizontally oriented section for accumulating the items along the path and an apparatus for transporting the items therealong. The apparatus may be either a plurality of parallel, spaced-apart endless belts or a plurality of conveying sections interconnected together to form an endless carrier. Each section...

A low lying horizontal furnace comprising a fireproof enclosure sealed by a top burns solid fuels which are gravity fed through a vertical feed chamber positioned over a feed aperture in the top of the furnace. An exhaust stack is placed over an exhaust aperture spaced away from the feed aperture for venting exhaust gases from the furnace. Elongated fins are fixed to the underside of the top for channeling the exhaust gases from the feed aperture to the exhaust aperture. The horizontal furnace p...

Embodiments of the present invention relate to display system comprising an electronic display device housed within a supporting fixture, where the supporting fixture may be capable of being arranged on a substantially horizontal surface such as a floor and walked over, or of being mounted on a non-horizontal surface, including a substantially vertical surface such as a wall. To this end, the electronic display device and supporting fixture may be thin and lightweight, while also being durable a...

An amplitude control circuit controls the amplitude of a correction signal periodically changing in a parabolic form at vertical scanning intervals based on the level of an amplitude control signal and applies an amplitude controlled output signal to an adder. The adder adds the amplitude controlled correction signal to the output signal of a low-pass filter and applies the resulting signal to a retrace scanning control circuit and a trace scanning control circuit. The retrace scanning control c...

An electron beam tends to slope downwardly as it is deflected horizontally to form a raster in a video display apparatus. The sloping of the beam can cause geometric errors in the raster, for example orthogonality and parallelogram errors. A raster correction circuit substantially offsets the downward slope of the electron beam by modulating a vertical deflection current with an induced horizontal-rate raster correction current, thereby substantially eliminating orthogonality and parallelogram e...

A horizontal articulated robot has a plurality of horizontal arms coupled by joint shafts, and a working shaft disposed at the extreme end of an extreme end arm among the horizontal arms has mounting portions of an end effector formed to both the upper and lower ends thereof. With this arrangement, there can be provided a horizontal articulated robot that can cope with various work transport forms and various types of works by one type of a robot by selectively using the upper and lower sides of...

An exercise machine includes: a bench for a user to lie upon; an actuator arm comprising a first end connected to the bench and a second end comprising a foot attachment for attaching to a human foot; the actuator arm comprising an actuator for moving the actuator arm such that a user's leg is moved into a stretching position; and a user control for causing the actuator to actuate.
