Title: Generator for tones of a musical scale
IPC: G10H5/00
Filed: 1974-10-28
Abstract: 1432328 Electrophonic musical instrument PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 28 Oct 1974 [31 Oct 1973] 46560/74 Heading G5J A generator for an electrophonic musical instrument comprises a master oscillator M and a chain of frequency converters FC 1 #FC 12 , the number and tone interval between which correspond to the tones of a musical scale. Output of M can be inputed to any one of the converters at pole 1 of changeover switches S 1 #S 12  and the other converters take the output of the preceding converter at pole 2. If the link betwee FC 12  and FC 1  is required it is made via frequency multiplier-by-two so the correctoctave is maintained. Transposition is achieved by choosing at which point the oscillator output is put into the chain. In a further embodiment an electronic switch replaces the changeover switch, or a single-pole switch may be used if the oscillator output can override the frequency converter output.

Title: Improvements in and relating to the manufacture of sulphuric acid
IPC: C01B17/765
Filed: 1965-11-05
Abstract: In a multi-stage SO2 contact oxidation process for the manufacture of sulphuric acid, the last stage of the oxidation process is interposed between two SO3-absorption stages, and the gas from the first SO3-absorption is heated to the reaction starting temperature of the last stage of the oxidation process by means of super-heated steam generated by hot gas derived from a combustion process for SO2-production.  In Fig. 1 filtered air from a blower 1 is blown through a drying tower 2 into a sulphur <PICT:1124807/C1/1> furnace 3 provided with a steam generator 4 and a superheater 5, where the SO2-containing gas from the burning process is cooled with the production of superheated steam.  The gas which is freed from dust in a filter 6 is adjusted with dry air from the tower 2 to the starting temperature of the first contact stage 7a. The gas is then cooled in a steam superheater (or steam generator) 8, passed through a second contact stage 7b, cooled in a steam superheater 9, and passed through a third contact stage 7c. A steam generator 10 and a feedwater preheater 11 cool the gas and the SO3 is absorbed in a first absorption tower 12. After leaving a mist separator 13 the resulting gas is heated with superheated steam in a heater 14, conducted to the last contact stage 7d, and passed into a steam generator 15 and a feedwater preheater 16.  It enters a second SO3-absorption tower 17, and after leaving a mist separator 18 is practically free from SO3. Fig. 2 (not shown) shows a modified cycle in which the superheated steam, before use to heat the gas from the first SO3-absorption stage, is further superheated by hot gas derived from the contact oxidation process.

Abstract: 1,128,399. Index cards &c. KLEER-VU INDUSTRIES, Inc. 31 Oct., 1966, No. 48676/66. Heading B6E. [Also in Division B5] A pager index card and a sheet of plastics material are joined together by the use of a tool which is vibrated by ultrasonic means to form a mechanical bond between the card and sheet. The plastics material may be a piece of transparent microfilm carrying photographic information, for use in an information retrieval system, and the mechanical bonds must be such that the film and card form an integral flat sheet. which will readily slide over a similar one. As shown, a paper card 41 has a window aperture covered by a transparent film of cellulose acetate, polyethylene terephthalate &c., and the tool D is vibrated at 18,000 to 35,000 cycles per second by a transducer of the magnetostrictive type. As the card is fed, the face 34,of the tool works diagonally across the aperture from the point 37 to the point 40. The tool pressure in the operation is from 2,000 to 20,000 pounds per square inch and the card is fed at ten to twenty feet-per minute. The positions of the plastics film and the card may be reversed, and the tool D then acts on the card. The edge of a paper card (44, Fig. 10) may be bonded to one edge of a film (45) so that the latter forms a, co-planar extension thereof.

Abstract: 1449038 Motor protective arrangements TELDIX GmbH 19 Oct 1973 [19 Oct 1972] 48885/73 Heading H2K A motor protective circuit is arranged to compare the voltage at the terminals of the motor 1 with a predetermined signal on switching on of the motor. To operate the motor a supply is applied to terminals 5 to energize a relay coil or to close contacts 3 whilst applying a signal via a delay element 8 to one terminal of an AND gate 6 which receives a signal at its inverting terminal from the motor terminals and only provides an output signal if the motor is not energized. Gate 6 also provides an output signal on disappearance of the signal at 5 provided that the element 8 is such as to continue its output for its delay time on deenergization. If the relay 3, 4 sticks to remain closed after the voltage at 5 is removed an AND gate 7 will provide an output signal through a timing element 9, signals from gate 6 and element 9 control an OR gate 10 connected to a bi-stable device 11 controlling a relay 12 and lamp 13.

Sewage is purified by filtration and/or absorption as it flows upwards from inlet 18 to outlet 22a through a bed of sand or coal, or similarly water may be softened by flowing through a bed of ion exchange resins, a height of medium (sand, coal or resins) equal to at least two bed dimeters being maintained above the outlet, whose weight keeps the lower part of the bed compact. Medium is fed into the top of the bed, spent medium is withdrawn through rotary valve 34. In Fig. 2, the containing vessel 10a, which may be circular, square or hexagonal in section, is vibrated vertically by solenoids 36 to assist the downward flow of medium. An additional, coarser layer of medium 23 encloses a perforate annular part of the vessel wall to retain fine particles of medium which would otherwise emerge with the filtrate. The upper part of the vessel ' may be greater in diameter than the lower part (Fig. 3, not shown), and the two parts may be made separately and connected by a flexible bellows (Fig. 4, not shown), so that the upper part alone may be vibrated. Inlet 18 has downward openings, and the inlet and outlet could be of other constructions than are shown. The vibration of the vessel could be effected mechanically and involve a rapid upstroke and slow downstroke. The vessel could be lined to reduce friction with the medium.
