Abstract: A separator for separating particles carried in a fluid carrying medium is disclosed. The separator includes an elongated duct and associated openings incorporated in a solid body. The duct is axisymmetrical relative to its longitudinal axis, and includes a curved wall portion having a curved cross-section taken along the longitudinal axis. An axisymmetrical opening located downstream of the curved wall portion leads from the duct into an axisymmetrical channel which is substantially radially disposed relative to the longitudinal axis. Continuation of the duct downstream of the opening is a discharge portion which is substantially colinear with the longitudinal axis. In operation, a substantial majority of the fluid carrying medium leaves the duct radially through the opening and channel in a state substantially free of particles.

Abstract: The present invention is directed to a three-group type wide angle zoom lens system which comprises, from the object to the image side, a first lens group of a negative refractive power movable along the optical axis for zooming, the first lens group including at least two positive lens elements and at least one negative lens element, a second lens group of a positive refractive power movable separately from the first lens group along the optical axis for zooming, the second lens group being of the triplet type formed by sandwitching a negative refractive power component in between a pair of positive refractive power components, and a third lens group of a positive refractive power movable separately from the first and second lens groups along the optical axis for zooming, the third lens group including at least one positive lens element, wherein the lens system fulfills the following condition:2.5<f.sub.III /f.sub.II <4.5wherein:f.sub.II and f.sub.

Abstract: A mass of energy transfer device is disclosed which is adapted for intermixing a liquid and a gas phase for the purpose of mass, heat or kinetic energy transfer between the phases. The transfer device includes a plurality of individual substantially tubular mixing elements each of which receives a high velocity spray of the liquid phase for substantially longitudinal travel therein and draws the gas phase into a throat and diffuser through a substantially axisymmetrical opening. The mixing elements are mounted into an enveloping vessel the interior of which is in fluid communication with a source of the gas phase. Efficiency of the device is disclosed to depend exponentially on the ratio of the momentum range of the liquid spray to the throat diameter which is related to the ratio of the slip velocity of the liquid and gas to the velocity of the gas.

Abstract: An improved spring wound prime mover capable of use with toys is provided. A plastic resin housing member comprises a pair of housing shells having complementary locking pawls and keeper members to permit a snap together assembly. The housing member further supports a spring member that can be selectively connected to a gear train assembly having a first and second gear ratio. The first gear ratio includes gears with a higher degree of mechanical strength than those engaged in the second gear ratio whereby a durable gear transmission is provided that can run smooth for driving the vehicle.

Abstract: A mirror arrangement for use in a single lens reflex camera which divides a light transmitted through an objective lens of the camera into a first portion led to a viewfinder and a second portion led to a light receptor which detects a focusing condition of the objective lens or the like, is disclosed. The mirror arrangement comprises a total reflection mirror surface and a plurality of light transmitting slits arranged thereon in parallel to each other. A width of each slit is limited less than 80.mu.. Pitches between two adjacent slits in the width direction are over than two times of an average width of all slits, and have at least two different values.

Abstract: A security system for ascertaining the authenticity of removable video game cartridges adapted to interface with a video game system having a CPU. The system includes the comparison of the contents of predetermined addresses in the memory unit of the game cartridges with a security message stored in the CPU, and the rejection of the cartridge unless the contents of these predetermined memory locations are the same as the security message. The system further includes means for displaying a proprietary notice message to the operator of the video game system before substantive interfacing between the CPU and remote software unit occurs. Control over game operation will occur only if the CPU recognizes the cartridge as an authorized unit.

Abstract: An entrapment assembly for use in a flying disc golf game. The entrapment assembly in one of its embodiments comprises an upright post mounted in the ground. An upwardly opening basket is mounted on the post and a plurality of outside chains are mounted on the post so that the lower ends thereof extend into the basket. The outside chains serve to absorb kinetic energy from a disc thrown against the assembly and thereby reduces its forward velocity. A disc deflection surface, such as a group of inside chains, extend outwardly and upwardly from a location adjacent the top of the basket to deflect the disc toward the basket after it has impacted the outside chains to ensure that the disc is caught in the basket.

Abstract: The disclosure is directed to an electrophotographic copying apparatus with variable magnification which is arranged to accurately register or align a leading edge of an electrostatic latent image with a leading edge of a copy paper sheet even when various copying magnifications are required, while synchronizing adjustments for the purpose are facilitated for an efficient copying operation.

Abstract: An internal combustion engine performance analyzing system is disclosed for displaying a number of operating characteristics, such as engine ignition and cylinder power, which exists under selectively controlled operating conditions. Simple connections to the engine provide the necessary signals to the solid-state electronic analyzer. Various pattern display modes may be selected. An anticipatory cylinder fire signal, which is related to crankshaft rotational degrees, permits a given cylinder to be shorted for the desired interval, regardless of the engine speed. This anticipatory cylinder fire signal is obtained from a servoed ramp waveform generator. Individual cylinder waveform patterns are synchronously and simultaneously displayed on an oscilloscope.
