Title: Electronic musical instruments
IPC: G10H5/00
Filed: 1975-05-07
Abstract: 1515181 Electronic musical instruments WURLITZER CO 7 May 1975 [3 June 1974] 19081/75 Heading G5S In a tone generator the array 12 of keys 13 is scanned sequentially by decoders 20, 21 so that on detecting a key closed a pulse is generated on line 48 which is used to enable the decoder circuit 68 in order to access ROM 67 and provide control pulses to a plurality of gate circuits 110, a basic frequency (500 KHz) being divided by a plurality of programmable dividers 100 set by the ROM 67 output and the gate circuits 110 and subsequently being transduced to give an audio tone. With the switches 46, 47 as shown the system is in a "lockout" mode (i.e. on closing a key the scan is halted until the tone no longer sounds) and with the switches both reversed the system is in a low note or high note "priority" mode (i.e. the scan continues, but is ignored until the end of the scan). Associated with each programmable divider is a gating circuit 110 which divides by 1 or 2 and a series of flip-flops (see Fig. 4, not shown) which generate octavely related outputs at each stage of the series. The system may be modified so that a plurality of keys may be played simultaneously, e.g. to play four keys there must be at least four dividers, there being a decoding circuit 68 and a ROM 67 for each four dividers. The tone generator may be on a single-integrated circuit. An output on line 65 can be used for controlling percussive voices from the keyboard.

Class 41 An electrolytic apparatus comprises a receptacle constituting the cathode, a removable main anode, a similar receptacle adapted to be clamped to the first in mouth-to-mouth register after removing the main anode, and means for inverting the clamped receptacles to transfer the electrolyte to the second receptacle prior to removal of the first receptacle for recovery of the electro-deposited material. As shown (Fig 2) a cell 3 has a removable main anode 1; a subsidiary anode 2, attached to a ring 7 which may be placed on an annular insulator 8 around the mouth of the cell has an upwards-extending portion 2<SP>1</SP>. A similar cell 3<SP>1</SP> (Fig. 1) may be clamped to the first, rim to rim. so that the part 2 of the subsidiary anode extends thereinto. The assembly is then swung about the trunnions 5<SP>1</SP> so as to invert the receptacles, the cell 3 is removed for recovery of electrodeposited material and the main anode is replaced in the cell 3<SP>1</SP> to continue the electrolysis. Means such as a pipe 13 (Fig. 2) may be provided to maintain an atmosphere of inert gas during the changeover. A sufficient current is passed through the subsidiary anode to provide cathodic protection of both receptacles against corrosive electrolytes while the main anode is withdrawn. The receptacles may be iron pots, and the main and subsidiary anodes may be graphite rods. The process is especially applicable to electrolysis of fused salts, and examples are given of the production of boron from a fused mixture of potassium chloride, potassium fluoride and boron trioxide, and of the production of calcium boride from a fused mixture of calcium chloride, calcium oxide and boron trioxide. The mixture of compounds is fused by heating the cell in a crucible or furnace, or by resistance or induction heating; a small current may be passed through the main anode during fusing to provide cathodic protection of the cell.

Title: Improvements in or relating to devices for measuring and/or indicating the diffusion of light in, or the turbidity of fluids and other transparent media
IPC: G01N21/53
Filed: 1937-07-12
Abstract: 479,662. Photometric apparatus. GAS ACCUMULATOR CO. (UNITED KINGDOM), Ltd. July 12, 1937, No. 19316. Convention date, July 11, 1936. [Class 40 (iii)] For measuring and/or indicating the diffusion of light in or the turbidity of a transparent medium, light is passed through the medium to be examined and two light - sensitive cells are arranged in the path of the rays in such a manner that an increase in the light diffusion by the medium will produce a proportional increase in the illumination of one of the cells and a corresponding decrease in the illumination of the other cell. The apparatus shown comprises a container for the medium M to be examined, and lenses 2, 5 for focusing light from a source 1, after passing through the container, on to an aperture in a photo-voltaic cell 6. After passing through the aperture, the light falls on a second cell 8 which is connected in series opposition to the cell 6 and to a measuring instrument 10. If the medium M is perfectly clear, only the cell 8 is activated, but if the light is dispersed by the medium, some of the rays fall on the cell 6 and a corresponding decrease in illumination of the cell 8 occurs. The consequent effect on the instrument 10 is a measure of the turbidity of the medium. In a modification, the cells are arranged in one and the same plane, the sensitive layer of one surrounding or being adjacent to that of the other.

Title: Improvements in or relating to radio transmitter arrangements
IPC: H03C3/00
Filed: 1937-07-16
Abstract: 481,855. Wireless transmitting systems. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. July 16, 1937, No. 19787. Convention date, July 16, 1936. [Class 40 (v)] Relates to radio transmitters in which carrier and side band energies are radiated from separate antennµ and comprises various arrangements in which the sidebands are radiated from an even plurality of antennµ. The carrier frequency fc generated at 15, Fig. 1, is amplified at 16 and fed to the antenna 18. The oscillator 1 generates a frequency F which together with the carrier frequency is impressed upon the modulator 19, the resultant frequency fc-F, being selected by the filter 21. The frequency F after passing through a buffer stage 3 is modulated at 5 by speech f v from microphone 7 after amplification at 9 and the two side bands F-fv, F +fv, are separated by filters 11, 13 and applied to modulators 23, 29 together with the frequency fc-F ; the outputs of each of these modulators contain one of the side bands fc + fv, fc-fv, which are fed to antennae 27, 33, respectively. If the radiators are not sufficiently spaced to prevent radiation coupling, it may be nullified by the use of link circuits to induce voltages in phase opposition. For short wave transmission the carrier and sideband radiators may consist of three dipoles, Fig. 6 (not shown) separated by a half wavelength and arranged vertically above one another, in which case a uniform field distribution is obtained as in the case of Fig. 1. In a simpler arrangement, Fig. 2 (not shown) both sidebands are radiated from the same antennae with a resulting figure of-eight field distribution. By using a plurality of side band radiators, 49, 51, 53 and 55, 57, 59, Fig. 4, spaced as shown, a more even angular field distribution is obtained. Specification 326.375, [Class 40 (v)], is referred to.

Title: Process for producing slow-acting potassium phosphate fertilizers
IPC: C05B7/00
Filed: 1970-04-24
Abstract: 1294748 Phosphate fertilizers MITSUBISHI CHEMICAL INDUSTRIES Ltd 24 April 1970 [24 April 1969] 19891/70 Heading ClA Potassium phosphate fertilizers are produced by calcining phosphate rock together with caustic potash and phosphoric acid. The preferred molar ratio of F 2 O 5  : CaO : K 2 O is 1À0: 1À7-3À7 : 1À2-2À0 with the molar ratio of P 2 O 5  in the phosphoric acid to that in the phosphate rock being 0À2-1À6 : 1À0. The product obtained is in the form of potassium-rhenanite, i.e. CaKPO 4 . The materials to be calcined may further contain a boron compound, e.g. borax, or boric acid with or without a magnesium compound, e.g. serpentine, forsterite, dunite, talc, enstatite, peridotite, dolomite, magnesite, brucite, MgSO 4 , MgCl 2 , Mg(NO 3 ) 2 , Mg 3 (PO 4 ) 2 . The boron compound may be present in an amount equivalent to 0À1-5À0 weight per cent B 2 O 3  in the calcined product and the magnesium compound may be present in an amount equivalent to 0À05-2À50 moles MgO per mole P 2 O 5  in the materials to be calcined. The product thus obtained may be a mixture of CaKPO 4 , MgKPO 4  and MgK 2 SiO 4 . The starting material is normally calcined, e.g. in an electric furnace, or a rotary kiln for 20-30 minutes at about 800-1100 C., though when a boron compound is present the calcination may be carried out from 700 C. The product of calcination may be cooled and neutralized by spraying with an acid whilst still hot, i.e. above 100 C., e.g. H 2 SO 4 , HCl, HNO 3 , H 3 PO 4  or its ammonium salt. The concentrations of the acids are preferably low enough to ensure sufficient volume to achieve uniform sprinkling, but high enough to ensure that all excess water is evaporated so as to give a dry product without resorting to a separate drying step, i.e. 10-70% by weight for phosphoric, sulphuric and nitric acids and 10-40% wt. for hydrochloric acid.

A self-aligning bearing has an outer metal member 1, an inner metal member 2 and an intermediate liner member 3 formed of a cured adhesive resin and a self-lubricating plastics material, said plastics material comprises etched P.T.F.E. particles mixed with an adhesive resin and said liner member 3 is adhered to one of said metal members by a layer of cured adhesive resin. In an embodiment the liner has equal volumes of epoxy-base resin and P.T.F.E. powder or flock mixed together and deposited by painting or spraying, for example, on to a backing material such as a woven fabric having threads of fibreglass, for example. The bearing face of the liner may be provided with an additional layer of P.T.F.E. particles and may be dusted with molybdenum disulphide, for example. The resin composition is allowed to set and the liner is then placed between flat heated platens of a press and pressed for about half an hour. Thus the resin is cured and the P.T.F.E. particles are fixed to the backing material. Another layer of resin is applied to the liner and allowed to set. The liner 30, Fig. 5, with its uncured second coat of resin 40 and a backer 50 is formed into a tube and placed between an outer ductile metal member 10 and an inner member 20. The resin 40 is cured by heating and thus bonds the liner 30 to the outer member 10. The assembly is then contracted by pressure to form the bearing shown in Fig. 6. In a modification the liner is fabricated from cloth woven of P.T.F.E. threads or of P.T.F.E. threads interwoven with threads of cotton, for example. The compressed cloth with its second coat of uncured resin 3, Fig. 1, is then formed into a tube and placed between an outer ductile metal member 1 and an inner member 2. The resin 3 is cured by heating and the assembly is then contracted under pressure to form the bearing shown in Fig. 2.
