Title: Improvements in musical instruments
IPC: G10H1/08
Filed: 1929-08-22
Abstract: 338,593. Jensen, C. A., (Lowrey, F. C.). Aug. 22, 1929. Electrically - vibrated instruments; pipe organs; organ manual coupler and stop actions; flue pipes. - Relates to instruments wherein sounders giving substantially sinewave notes are combined to produce complex tones synthetically, and consists in providing independent controls for regulating the intensity according as to whether a sounder is speaking as a fundamental or as an upper partial. Figs. 1 and 4 show a tuning-fork instrument, forks F, which may also be struck by hammers 38, being vibrated, on closure of key contacts 16, 17, by magnets 22, magnets 41 simultaneously lifting dampers 39. The forks are connected by springs 48 to a soundboard 47. A pulsator P, rotated by a timed device 50, produces pulsations, preferably of the natural period of the fork, in the current from cells 30, the number of which cells in circuit may be varied to vary the voltage and thereby the general intensity. Contacts 18, 19 usually remain closed, for sounding fundamental tones, current passing, on closure of key contacts 16, 17, from the cells 30, through a rocking resistance segment 35 controlling the intensity of the fundamentals, contacts 17, 16, 18, 19, forkmagnet 22, damper relay-magnet 24, and pulsator P. If the same fork is required to sound as the first (or second) harmonic in a complex tone, contacts 52, 53 (or 56, 57) are closed by a stop, a corresponding circuit through another intensity segment 75 (or 78), key contacts 15, 14 (or 13, 12) of the appropriate key, lead 54 (or 58), and contacts 53, 52 (or 57, 56), being completed. Any one key therefore closes pairs of contacts 12 - -17, thus sounding such elements in the complex tone as are represented by closed contacts 18, 19, 52, 53, 56, 57, and each element of the tone being under a separate intensity control 35, 75 or 78. Fig. 8 shows a pipe organ wherein the intensity control of each pure note is obtained by sounding a greater or smaller number of pipes 90 - - 92 in unison. General intensity may be regulated by the swell box 93. For a single note as (say) a fundamental, current passes from battery 30, through the intensity resistance-segment 35, key contacts 17, 16, " fundamental stop " contacts 18, 19 to relay-magnet 122. The shape of the core 114, Fig. 10, and the path of the pivoted armature 110, are arranged so as to produce a movement of a cross-head 111 on the armature which is proportional to the current. The head 111 is inclined, and thus makes contact successively with one or more of the spring fingers 104, 106, 108 guided between the teeth of a comb 109, current then passing from a battery 102, through the bracket 112 and the armature 110, to one or more of the pipe-controlling magnets 98 - - 100. The pipes 90 - - 92, of which there may be any number for each note, may be voiced of unequal loudness. One type of sonorous bodies may be used for the fundamentals, and another for the upper partials.

Title: A process for the production of tri-sodium phosphate
IPC: A63H3/40
Filed: 1931-09-14
Abstract: Tri-sodium phosphate poor in water is obtained from di-sodium phosphate poor in or free from water by treatment thereof with a melt or concentrated solution of caustic soda of such concentration that the water content of the mixture corresponds to the desired water content in the end product.  In one example Na2HPO42H2O is introduced into a melt or concentrated solution of caustic soda at 50-80 DEG  C. to obtain a tri-sodium phosphate having three or seven molecules of water of crystallization.  The caustic soda may be introduced into the di-sodium phosphate, and the reaction may be effected in an autoclave or under reflux to avoid loss of water.  In another example anhydrous disodium phosphate is mixed with caustic soda (anhydrous or with added water) in a ball mill in a current of heated air to obtain a trisodium phosphate having one or five molecules of water of crystallization.

Abstract: 872,444. Electric copying-machines. LANCASHIRE DYNAMO ELECTRONIC PRODUCTS Ltd. Nov. 5, 1958 [Aug. 16, 1957], No. 25943/57. Class 38 (6). [Also in Group XL (b)] In apparatus for following the outline of a visual pattern a rotating light spot intersects the edge of the pattern the point in the rotation at which the intersection takes place being used to determine the direction of movement of the apparatus. As shown, a spot of light produced by a lens and aperture is directed by fixed mirror C on to mirror D mounted on the end of a motor shaft and inclined to it in such a manner as to produce a ring of light as shown in Fig. 2a. This light may be reflected from a pattern on an opaque background but in the arrangement shown that part of the scanning circle which falls outside the opaque pattern passes through a transparent support and is received by a photo-electric multiplier 10 (Fig. 6). The output of the cell is amplified and produces the square wave pulses shown in Fig. 2b. These pulses are differentiated to produce sampling pulses (Fig. 2b) which pulses are fed to phasesensitive detectors 15, 16 fed with reference sine waves from a source 20 in synchronism with the motor which rotates mirror D. These sine waves are separated in phase by 90 degrees by means of phase-shifter 22. Thus the outputs of the phase-sensitive detectors are two voltages representing respectively the sine and cosine components of the angle (Fig. 2a). These voltages are smoothed at 21 and used to control the output of Ward-Leonard generators G1, G2 feeding motors M1 M2 which each drive the tracing head in one of the co-ordinate directions at speeds V sin # and V cos # so that the tracer follows the outline of the pattern.
