A bell hammer is suspended from a horizntal axle that is rotatably fixed at one end, internally to a wall of the bell and at the other end of the axle to the chime mechanism of the clock so that the bell hammer strikes the wall of the bell when actuated by the chime mechanism of the clock.

Abstract: An electrical clock is provided in which pulses of a 10% duty cycle are repeatedly applied at a one second rate to a solenoid which attracts an armature attached to a reciprocating ratchet once every second, the reciprocating ratchet being returned to a neutral position between each pulse. The reciprocating ratchet drives a toothed wheel which is located on a main axis of the clock frame view suitable pawls. The second hand of the clock is directly coupled by a second hand shaft to the toothed wheel. The toothed wheel, by means of a pinion, drives an intermediate gear which is located outbound from the main axis. The intermediate gear drives a minute gear, the minute gear being mounted on a minute tube concentric with the second hand shaft. The minute hand is directly affixed to the minute hand tube. The minute gear, by means of a pinion, drives an outbound motion gear, the motion gear in turn driving an hour gear coupled to an hour tube whose axis is concentric with the second shaft and the minute tube.

Abstract: A portable electronic voting machine suitable for use in simple elections includes a number of spring-loaded switches normally centered and movable upward to a vote position to select a candidate and downward to an erase position to erase a previous selection that has not yet been entered with a light above each switch indicating the state of selection. An n of m counter settable prior to the election to the maximum number of votes that may be cast by a voter and associated logical circuitry prevents more than that selected number from being entered by a single voter. An election official operates a voter enable switch to light a ready light and enables the apparatus to receive vote selections.

Abstract: The present electromagnetic pickup and method, and the piano incorporating the pickup, make use of a protuberant magnetic pole piece portion which is so constructed and related that (a) the lines of magnetic force loop back therefrom, and (b) the concentration of such lines is sharply more dense on one side of such portion than on the other side thereof (the magnetic field adjacent such portion being therefore highly asymmetrical). The tine tip is caused to vibrate adjacent such portion, which produces in an associated coil a musical signal characterized by a high degree of brilliance and piano-like musicality -- without an excess of the second harmonic. The pole piece portion is preferably offset from the axis of the coil. Preferably, there are two such offset portions, spaced on opposite sides of the coil axis, and each has a peak shaped as a substantial point or edge.

Abstract: An electric alarm watch with an electro-optical display and an alarm mechanism which is released by a time-selecting device including a manually displaceable time-selector mounted for movement to different positions corresponding to the time of day for selecting the time at which the alarm goes off. At each position of the time-selector a particular set or combination of electrically conducting members is engaged by an electrically conducting zone or brush for producing an electronic signal which is peculiar to that particular position of the time-selector. A decoder may be used for receiving this signal and supplying it in decoded form to a comparator which compares the information from the time-selector with that received from the time-display portion of the watch. The alarm goes off when the information from the watch circuit is in concordance with that received from the time-selector.

Abstract: A circuit for producing a chorus effect in an electronic musical instrument. The circuit includes N separate channels, where N is an integer greater than one, with each channel having an analog delay line to which a tone signal is applied. Each delay line frequency modulates the applied tone signal at a subaudio rate in response to changes in the frequency of clock pulses applied to the delay lines. The delay variations in one delay line are out of phase with the delay variation in every other delay line by a selected amount which is normally 360.degree./N. Clock pulses are generated by means including a nonlinear circuit to compensate for the nonlinearity in the frequency interval between tones in the musical scale. The outputs from the delay lines after filtering of the clock frequency components are utilized to produce the desired chorus effect output from the instrument.

Each string-fret pair of the stringed instrument is assigned a given musical tone, preferably in accordance with normal tuning of the instrument, and means are provided for producing a corresponding voltage when a string-fret pair is closed by pressing the string against the fret. When two or more string-fret pairs are simultaneously closed, the output voltage corresponding to the highest frequency musical tone associated with the closed string-fret pairs is produced.
