Abstract: In the embodiments shown, the device comprises a turbine wheel, rotatively journaled, having a peripheral, grooved surface onto which rounds of shot are impelled, under steam pressure, to rotate the wheel so that torque power might be derived therefrom. The turbine wheel, in turn, rotates a pulley -- by means of a drive belt -- which operates a sluice-type gating device. The latter device cyclically opens and closes off the pressured steam supply, and feeds a missile -- a round of shot -- to a conduit which terminates in adjacency to the turbine wheel, in order that the round, the missile, will be impelled through the conduit to impact upon the grooved surface of the turbine wheel and deliver a frictional, glancing, energy-transferring blow to the turbine wheel. The turbine wheel is rotatively carried on a support which is pivotally mounted, so that the turbine wheel can be moved into and out of proximity with the missile-impelling conduit in order to optimize missile impact.

Abstract: The invention concerns a device for separating isotopes. A gas containing the isotopes to be separated is excited by a radiation having an intermediate frequency between the central frequencies of the two absorption lines of the two isotopes, those two lines coinciding partly by Doppler enlarging, so as to make it possible to separate subsequently the excited molecules according to the direction of their motion. Application to isotopic enriching.

Abstract: A housing for a fluid actuated hand tool and of the type for use as a grinder, polisher, or the like, the housing comprising a cylindrical casing formed having a cavity extending substantially inwardly thereof, the rearward portion of the casing being formed having the various passages and channels through which the pressurized air or other fluids under pressure may traverse upon manipulation of a valve for attaining entrance to the motor encased within the cavity and to induce its actuation and rotation as during usage. The casing is comprised of an integral and unitized structure, having the motor cavity formed during its molding, and a cap threads onto the end of the casing so as to hermetically secure the motor therein during tool fabrication and application.

Abstract: Disclosed is a digital arpeggio system for an electronic organ that through the use of digital techniques permits arpeggios, note sequences as well as strum, multi, organ, and normal modes of operation to be played automatically. Two counters scan by counting through an 8.times.8 matrix of 64 words covering the 61 notes of an organ in rapid sequence upon the playing of one or more organ keys. Each word is fed to a corresponding one of 61 decoders, one for each note of the keyboard. If a corresponding key has been played, the decoder provides a signal to a corresponding pulser circuit which enable a corresponding keyer to transmit an audio signal from an audio oscillator corresponding to the played key to an output system and loudspeaker. The two counters are stopped by a clock control while the note is sounded and then the counters are enabled by the counter control to continue counting through the matrix until the next actuated key is located.

Abstract: A vegetable extract in the form of grains which dissolve instantaneously in water and which have a porous, continuous structure, a smooth surface and an apparent density of from 50 to 300 g/l.A process for the production of a vegetable extract as described above, which comprises extruding a vegetable extract in powder or paste form into a chamber where a subatmospheric pressure prevails, and cutting the extruded product into fragments.

Abstract: A conveyor, particularly for feeding preshaped pieces of cardboard to a machine for packaging cigarettes into hinged lid packets, and in which a guide is provided to control the vertical position of said pieces when they fall from the bottom of an upper vessel on to said conveyor under the action of an extractor, said guide being movable to and from a working position in which the guide interferes with the falling path of said pieces.

Abstract: A liquid dispenser having a metering chamber and a supply chamber disposed in side by side relationship and adapted for liquid communication with one another through a normally open supply valve. The liquid in the chambers are maintained at the same level. An outlet drain from the metering chamber through which liquid may be drained from the metering chamber and a normally closed outlet valve for controlling the flow of liquid through the outlet drain is provided. The supply valve and said outlet valve co-operate in such manner that upon opening the outlet valve to dispense liquid from the metering chamber, the supply valve closes and then subsequently re-opens for replenishing the metering chamber from the supply chamber only after the outlet valve has closed.

Abstract: This invention provides improvements to apparatus for automatically cleaning surfaces submerged in a liquid. Thus, there is provided an apparatus having a pivotally displaceable float by means of which the apparatus is caused to turn around when migrating up an upright surface so as not to break the surface of the liquid. The pivotal axis of the float is further tiltable, a tilting float being provided to tilt the privotal axis to assist in displacing the float. The apparatus further has a sealing flange which has perimetral concertina-like folds so as to be resiliently extensible. Still further, the apparatus has a cleaning head, the region thereof that engages the surface to be cleaned having zones with differing frictional characteristics to cater for various surfaces. In a preferred embodiment this is effected by providing sockets in the cleaning head in which studs having the required frictional characteristics are secured.

Abstract: A pressure differential indicator for indicating a change in a fluid pressure differential across a component in a fluid system, such as an oil filter, has piston means, means for communicating fluid pressures of said system upstream and downstream of said component to opposite sides of said piston means, respectively, and differential means associated with the piston means for normally balancing the resultant forces of said pressure on opposite sides of said piston means at a given predetermined pressure differential across said component whereby said piston means is responsive to an increase or decrease in the pressure differential above or below said predetermined differential pressure to indicate a clean or clogged filter condition. Means are provided for holding the piston means in its last position upon relief of said first and second pressures to indicate the operating filter condition when the system is not operating.

Abstract: A material for use in making electrical contacts is produced in a powder form suitable for later processing into electrical contacts by standard metallurgical techniques. The material consists of a first metal, such as silver, and the oxide of a second metal, such as cadmium, added to the first metal in a proportion up to the limits of solubility of the second metal in the first metal. An oxide of a third metal having a low electronic work function level, such as lithium oxide, is added and uniformly distributed on the surfaces of the powder particles by precipitation. A fourth metal, such as tellurium, that is insoluble in the first metal is also added to provide selected characteristics.
