Abstract: An apparatus cleans the exhaust gases of a motorcycle by feeding secondary air to the exhaust path of the engine. The amount of secondary air fed is controlled in proportion to the speed of the motorcycle. The apparatus includes a control valve which is operated to be opened and closed in response to the opening and closing of the throttle valve of a carburetor of the engine.

Abstract: A gas and vapor separator includes an axial fan with blade members which carry an absorbing material. A power means, such as an electric motor, rotates the fan, which causes the adulterated fluid to pass through the apparatus. As the fan blades contact the fluid, the desiccant material absorbs the undesirable elements in the fluid and simultaneously expels the cleansed fluid. The centrifugal force which acts on the absorbed matter causes said matter to radially translate in an outwardly fashion into a circular collector which entraps and retains the absorbed matter. The desiccant material is thereby continuously purged and capable of continuously cleansing the adulterated fluid.

Abstract: This invention relates to systems for clearing smoke from buildings when a fire occurs therein. Smoke detectors are provided in communal units in the building and means are provided for maintaining the pressure in accommodation units of the building above that in the communal units under normal conditions, so that there is a flow of air from the accommodation units to the communal units through the cracks in the doorways separating the accommodation units from the communal units. This flow of air ensures that, if a fire occurs in any one of the accommodation units, smoke will be carried into one of the communal units where it will be detected by one of the smoke detectors. When smoke is detected, conditions are reversed, so that the pressure in the communal units is maintained above that in the accommodation units. As a result, there will be a flow of air from the communal units to the accommodation units, once again through the cracks in the doorways.

Abstract: For lapping the surfaces defining a hole in a wiredrawing die of diamond or artificial material, one or more transducers are excited by respective ultrasonic generators to produce mechanical vibrations imparted to lapping needles. Turntables arranged opposite to the tips of the lapping needles are rotated from a common drive shaft and, simultaneously, each rolled or swayed about an axis passing through the die mounted thereon. A cam or crank mechanism driven from the common drive shaft is employed for the rolling motion of each turntable. The apparatus further comprises means for fine adjustment of the position of each turntable relative to the lapping needle in a plane at right angles therewith, and means for yieldably urging the die on the turntable against the lapping needle under adjustable pressure.

Abstract: A one-piece device for holding balls having an integral clip for clipping on the top edge of the wearer's garment. The device may be made from plastic or any other material having some resiliency enabling the temporary retention of the balls. The device is arranged so that linear translation permits the ball to be inserted into or removed from the device.

Abstract: In a phonograph of the type wherein, during playback, a pickup arm travels in sliding contact with an overlying intermediate vibrator for transmission of stylus vibrations thereto, a lever is fulcrumed at its intermediate point on the intermediate vibrator. A constant force is applied to one end of the lever, as by a spring, and the other lever end is urged against a loudspeaker diaphragm rigidly supported by the phonograph casing, so that the vibrations of the intermediate vibrator are transmitted via the lever to the diaphragm to cause same to produce corresponding sound waves. Preferably, the distance between the said other end and fulcrum of the lever is at least equal to the distance between the said one end and fulcrum of the lever.

Abstract: A continuous transport system for serving an urban region, for example, for ublic transport. The transport system includes at least one looped main track which cooperates with at least one station track. The main track conveys platforms with removable cabins disposed thereon at a constant speed, and the cabins are adapted to be transferred to similar platforms provided on the station track. The station track varies the speed of the cabins therealong to permit embarkation and disembarkation therefrom.

Abstract: A knitting machine comprises a stationary part and a rotary part, a data transmitter associated with the stationary part and a data receiver associated with the rotary part. The rotary part carries a photo-receiver either on its axis of rotation or arranged to follow a predetermined path as the rotary part rotates, said photo-receiver being connected to the data receiver. The stationary part carries a photo-emitter or a configuration of photo-emitters located so as to illuminate the photo-receiver or the path of the photo-receiver, the photo-emitter or photo-emitter configuration being connected to the data transmitter to illuminate the photo-receiver or the path of the photo-receiver with a train of light pulses corresponding to the data transmitted so that the photo-receiver produces a train of electrical pulses corresponding to the data transmitted.

Abstract: A device for manufacturing corrugated plastic tube by subjecting an internally unsupported corrugated plastic tube, at a temperature between 30.degree. and 70.degree. C, to the simultaneous action of at least two punching members in one or in two corrugations.A device comprising a guide for corrugated plastic tube, and punching means with an operating member for simultaneously acting upon at least two punching members spaced a short distance from each other.

Abstract: An apparatus for imparting a relief effect to patterns on even surfaces. A cylinder is formed by winding upon itself a thick metal sheet which is provided with holes therethrough. A doctor permits the depositing of a coat of a colorless varnish onto the surface to be coated when the surface is translated linearly relative to the rotatable cylinder.

Abstract: A number of wires are gathered together and bound with an armoring material in the shape of a band. The wires in this condition are drawn by means of a wire drawing apparatus having dies and a capstan. A plurality of bundles of such wires are gathered together and bound in the same way as in the foregoing to form a composite bundle body, which is further drawn, and these processes are repeated until at least filaments of a specified diameter are obtained in quantities.

Abstract: A selective and proportional hydraulic remote control device including jacks which are connected to a high pressure oil circuit commutated by distributors. The distributors are remotely controlled by a low pressure circuit which is connected to a fluid emitter. The emitter causes the input flow of the low pressure circuit for the distributors to vary. Only the input to the low pressure circuit takes place from the emitter through connections, while the return to the tank takes place from the distributors through jets, the sections of which are fixed. The same distributor can be controlled from several different locations.

Immersed in the semiconductor is at least one other second electrode whose polarity differs from the polarity of the first electrode. The electric current passing through the electrodes heats up the semiconductor material whose heat is thermally transferred through the first electrode into a material, such as aluminum, to be melted. The first electrode may constitute a graphitic ungrounded casing. The heated semiconductor or liquid resistor maintains a uniform temperature, and uniformly transmits heat. The apparatus makes practical 100-200 kilowatts per square foot of surface area times 3-4 feet of immersion depth.
