Title: Electronic musical instrument capable of providing a third type of musical tones by operation of two keyboards in addition to the ordinary melody and chord tones
IPC: G10H1/04
Filed: 1973-05-30
Abstract: 1399179 Electrophonic musical instrument NIPPON GAKKI SEIZO KK 30 May 1973 [30 May 1972 (4)] 25765/73 Heading G5J With upper (melody) keyboard 13 and lower (chord) keyboard 15 conventionally connecting appropriate tone generators 11 via keyers 12, 14 through channels 1 and II to output amplifier 17 and loudspeaker 18, a third channel III to output is provided by gating at 20 signals from those tone generators already selected by chord keyboard 15 so that such tones, synchronized with melody keyboard 13 by being given percussive envelope form when any melody key is pressed, or sustained as long as such a key is pressed, are fed additionally to output. In each channel tone colouring filters 16, 19, 22 modify the tones. Gate 20 is controlled via detector 21 operated either directly by any keyswitch in keyer 12, or by detecting the presence of any melody tone signal switched on by keyer 12. When operated by keyswitches, a monostable multivibrator in detector 21 is triggered by any keyswitch, resetting itself after a fixed time. To produce a percussive envelope, multivibrator step output is converted to exponential decay by adjustable R-C differentiating circuit, with diode elimination of reverse pulses at reset. When operated by the presence of a signal, the melody tone is amplified, rectified, smoothed and finally passed to an adjustable R-C differentiating circuit if percussive envelope is required. In all cases the detector output controls a FET as gate 20. In an alternative embodiment (Fig. 6, not shown), gate 20 is duplicated, feeding separate tone colouring filters with percussive and sustained envelopes; their outputs, combined via volume controls and stop switches, are fed to the amplifier 7 and loud-speaker 18 optionally via a modulator driven by low frequency oscillator providing amplitude, frequency or tone colour vibrate or tremolo modulation. In a third embodiment (Fig. 9, not shown), the melody keyboard is divided into octave ranges, controlling separate detectors and gates, each feeding a separate tone colour filter. The notes passed by each gate, either percussive or sustained, agree in position in an octave with those played on the chord keyboard, but their footage (octave) rises in step with the octave of melody keys controlling that gate.

Title: Improvements in or relating to articles or pieces of polyhexamethylene adipamide
IPC: B29B13/00
Filed: 1951-11-06
Abstract: Articles obtained from polyhexamethylene adipamide by pressure moulding, injection moulding, extrusion or centrifugal casting are stabilized dimensionally by heating to 400-500 DEG  F. and then cooling the articles to a temperature not above 212 DEG  F., the cooling being sufficiently slow to prevent the development of strain. Additionally the article may be boiled in water or treated with steam after the heat treatment to adjust its water content to 2-3 per cent or more, depending upon the conditions under which the article will be used.  To obtain uniformity of water content throughout the article, the water content may be increased to beyond the value required and the article then partially dried.  If the article is to be machined, rough machining may be done before or after the heat treatment and finish machining after the heat treatment and after the water or steam treatment, if used.  When rough machining is performed before the heat treatment, large articles may be boiled prior to machining to effect partial relief of strain and to facilitate machining.  The articles must then be dried before the heat treatment to prevent blistering.  In examples (1) nylon rod was pressure moulded from flake, heated in an oil bath to 450 DEG  F., the temperature maintained for 15 minutes and the rod cooled to room temperature over 2 1/2 hours.  Gear blanks were machined from the rod and the blanks boiled in water to a water content of 2 1/2 per cent. The blanks were then finish machined.  (2) 3/4 inch nylon rod was cut into pieces, heated at 450 DEG  F. for 10 minutes and cooled over 2 hours.  The pieces were boiled for 24 hours in water and then machined to produce rollers.  (3) A nylon cylinder was obtained by centrifugal casting, boiled in water and then cut into rings.  The rings were dried, heat treated at 450-475 DEG  F. for 15 minutes and cooled by standing in air.  The rings were then boiled to a water content of 4-5 per cent, partially dried to a water content of 2 1/2 per cent and finish machined.  (4) Nylon rings were cut from a cylinder, heat treated at 450 DEG  F. for an hour and cooled over several hours to room temperature.  Saw cuts were made in the rings, the resulting gaps remaining constant in width in contrast to those made in untreated rings.  (5) Similar to (4) but with rings obtained from a heat-treated rod.  Specification 730,641 is referred to.
