Abstract: A continuous self-cleaning filter for liquids has an outer resonant tube concentrically mounted around an inner composite tube in spaced relationship providing an annular chamber between them. There is an inflow at one end of the annular chamber for the liquid and an outflow at the other end for residual concentrate. The inner composite tube has an outlet at one end for clear effluent and a closed opposite end. A relatively thin walled perforate liner enveloped in a filter blanket comprises the composite tube.

Abstract: A wrist compass is formed with a base member having straps at each side for strapping to a user's wrist and with a detachable compass body having complementary interengaging surfaces for removably securing the compass body to the base member. The base member also is provided with folding lens and sight line elements to overlie the attached compass face in a folded position and to be erected to a sighting position when desired. The lens and sight line elements are preferably formed entirely of transparent material so that the compass face is visible when the elements are folded thereover.

Abstract: A double-twist twister mechanism includes a pair of assemblies which rotate about oblique intersecting axes, support a nonrotating spool carrier and have portions extending through each other. The assemblies are connected together for concurrent rotation by an external elastic member which is passable over the spool carrier into engagement with concentrically arranged fasteners on both assemblies.

Abstract: Process and apparatus for the preparation of extracts from ground roasted coffee and the like comprising subjecting ground roasted coffee sequentially to (a) exhaustive extraction of the solubles at a temperature at which no substantial hydrolysis of coffee solids occurs, (b) heating for a short time to a temperature at which insoluble coffee solids are transformed into extractable substances, and (c) exhaustive leaching at a temperature within the same range as that used for step (a).

Abstract: A brake band is provided which is useful particularly in connection with transmissions. The band has welded at each free end thereof a bracket. The brackets are provided with recesses to receive the actuating struts which abut against one end of the recesses to cause closing of the band in a drum.

Abstract: Apparatus is provided for longitudinally inserting a rotor having a shaft into a stator having an opening adapted to receive the rotor. The apparatus includes a stationary support having an elongated cantilevered beam extending horizontally outwardly therefrom, and a pedestal support spaced horizontally from the stationary support. Cradles are provided on the pedestal support and on the distal end of the beam to support the ends of the rotor shaft. A carriage is mounted for movement between the supports in a direction parallel to the longitudinal axis of the beam, and is adapted to support the stator. The carriage has means for selectively adjusting the position of the stator relative to to the supported rotor in multiple directions. The carriage is moved away from the stationary support to cause the stator to envelop the rotor.

Abstract: The present invention provides a sound producing device that can be combined with a toy hobby horse. A whinny or neigh sound can be produced by child operated movement of reins to stress and subsequently release a weight loaded spring lever. A coil spring is positioned to contact the spring lever for the generation of the noise. A one-way stop mechanism can retain the weighted spring lever until it is placed under sufficient stress by the operator to effectuate its release.

Abstract: An electronic antiskid control device which comprises a frequency multiplier of the phase locked-loop type, which receives repetitive pulses of predetermined frequency representing the speed of one wheel. The phase locked-loop multiplier normally outputs a second pulse signal, the frequency of which is normally equal to the frequency of the wheel speed signal multiplied by a given number. A digital counter which is periodically reset at a frequency equal to that of the wheel speed signal measures the number of pulses of the second pulse signal during each period. The measured number is transfered into a memory element and calculating apparatus responsive to the value stored in the memory element control an antiskid cycle. In operation under normal conditions, the number stored in the memory element is constant and has no action on the calculating apparatus.

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 enables 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: An arrangement for the electrical control of the keyboard of a video or audio tape recorder includes electromechanical levers acting on the usual rod system associated with the keyboard in substitution of the conventional keys. The levers are essentially bellcranks and are associated with tumblers and electromagnets.

Abstract: Faulty alternator diodes are identified by detection of a voltage ripple across the terminals of the automotive storage battery. A diode is forward biased whenever the battery has adequate charge to be designated a "good battery", and the forward bias condition is utilized as a reference potential. A voltage divider scales the reference potential, and couples it to the inverting terminal of a comparator. The non-inverting terminal is biased at a predetermined differential from the inverting terminal, and the probe signal is AC coupled to the non-inverting terminal. If a diode is bad, the superposition of the AC with the bias will switch the comparator and energize a light emitting diode.
