Title: Methods of producing tones
IPC: G10H5/00
Filed: 1968-08-12
Abstract: 1,221,490. Pulse frequency changers and dividers. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 12 Aug., 1968 [15 Aug., 1967], No. 38384/68. Heading H3T. [Also in Division G5] A pulse frequency changing circuit, Fig. 3, in which the number of pulses at an output E equals the number of pulses applied at an input A less the number of pulses applied at an input D,comprises a group of logic circuits L 1 -L 9  interconnected as shown and arranged so that pulses applied at A produce an output at E except when cut off by pulses applied at D. The logic circuits each produce an output at one level when the inputs are all at the same level and an output of the other level when the inputs differ. Outputs from the circuit are also made available at terminals O and G. By connecting output O to input D, Fig. 4a (not shown), the circuit may function to divide by two a pulse input at A. Two such circuits interconnected as illustrated in Fig. 6a (not shown.) will divide by three. Three circuit interconnected as illustrated in Fig. 7a (not shown) divide by five. The Specification includes the truth table associated with the circuit and gives detailed waveforms of the operation in each mode. Applications of the circuit to the production of a series of tones forming an approximately equally temperred scale for use in an electronic musical instrument (see Divisions G4-G6) are described with reference to Figs. 8 and 9 (not shown). In another circuit, Fig. 1, pulses applied at S 2  are applied through a gate D 3 , D 4 , R 2  and produce an output at S 1  except when the gate is cut off by pulses applied from S 8  through a divider M, whereby the output at S 1  equals the number of pulses at S 2  less the number of pulses at S 3  divided by M. The output from M controls a flip-flop circuit FF, the potential from which at terminal 3 blocks gate D 3  D 4 , R 2  and the potential from which at terminal 4 appears at second gate D 1 , D 2 , R 1 . Each pulse from M triggers FF to cut off the translation of a pulse from S 2  to S 1  the termination of the S 2  pulse resetting FF via gate D 1 , D 2 , R 1  so that subsequent pulses are translated until FF is again triggered.

Title: Process for the manufacture of a printing, typing and writing sheet having a high degree of opacity
IPC: B29C39/00
Filed: 1963-09-30
Abstract: 1,002,407. Making opaque films. FELDMUHLE A.G. Sept. 30, 1963 [Sept. 28, 1962], No. 38471/63. Heading B5B. Printing, typing or writing thin sheet or film having a high degree of opacity and which can serve as a substitute for paper is made by casting a solution of a solid organic polymeric material in a volatile organic solvent on a smooth support, incorporating in the solution a volatile organic liquid that is miscible with the solvent and which, when present in sufficient concentration, precipitates the polymeric material in a finely divided form, causing the concentration of the liquid to attain this value, and evaporating off the whole of the solvent and the liquid at a temperature below that at which the precipitated particles coalesce, the evaporation conditions and the solvent and the liquid being so chosen that the particles do not redissolve during the evaporation step and the polymeric material remaining after evaporation can be removed as an opaque thin sheet or film from the support. The two organic liquids are then completely evaporated off at a temperature below the m.pt. of the material and the opaque film or sheet thereby formed stripped from the support. The non-dissolving liquid may be less volatile than the solvent and in this case the solution of the film-forming material to be cast may contain a proportion of the less volatile liquid (but not sufficient to cause any precipitation of the material) and no more of this liquid is added to the cast layer of solution. The solution may in either case contain dyestuffs or organic pigments. The temperature at which the organic liquids are evaporated preferably does not exceed 90‹ C. and more preferably is 50‹ and 70‹ C. The film-forming material may be cellulose acetate, propionate or butyrate or a mixed cellulose ester, nitrocellulose, a highly substituted cellulose ether, polyvinyl chloride and its copolymers with vinyl acetate, acrylic acid esters, vinylidene chloride, polystyrene, and incompletely cured condensation products of formaldehyde with phenol, urea and melamine. The volatile solvents used may be (according to the nature of the film-forming material) acetone, ethyl acetate, ethyl alcohol, cyclohexanone, dioxane, tetrahydrofuran, chlorinated hydrocarbons, and aromatic hydrocarbons. The volatile non- solvents (according to the nature of the filmforming material) may be isopropanol, butanol, isobutanol, benzene, toluene, aliphatic hydrocarbons, and chlorinated hydrocarbons. The solutions may contain plasticizers and small proportions of stabilizers.

Title: Improvements in or relating to remote reading means
Inventor: LAPSLEY ROBERT SNEDDON BERNARD
IPC: E06B3/94
Filed: 1968-08-13
Abstract: 1,253,826. Remote meter reading. PARKINSON COWAN Ltd. 6 Aug., 1969 [13 Aug., 1968], no. 38622/68. Heading G4H.  A device for remotely reading the counting register of, e.g. a gas meter, comprises a series of index members of different numerical significance driven from the meter, a corresponding series of switching elements responsive to movement of the index members, a means for transmitting an electrical current through the switching elements, a retaining means for holding the index means stationary during the electrical transmission and a means remote from the meter operated by the electrical transmission for recording the positions of the index members. The switching elements comprise a pair of electrically connected contacts 30 which co-operate with a series contacts 29, circumferentially spaced on an index wheel, and a contact ring. When the meter is to be read a solenoid 32 is activated which locks the index wheels in position, ensures that the index members are aligned at a digital position and engages the contacts 30 with the contacts 29. A current is then passed through each of the leads 35 in succession and a series of signals is received on the lines 31 which correspond to the meter reading. In a modification the contacts 29 are replaced by four concentric contact groups to enable the reading to be transmitted in binary coded decimal. A clutch may be provided to allow continued movement of the meter mechanism while the index members are held stationary for reading. Each meter is provided with an identification code by means of differing interconnections between the lines 37 and 31. The code may be recorded together with the meter reading by passing a current through each of the leads 37 and recording the output on the lines 31. The remote reading and recording device may be portable and comprises a decimal to binary encoder to which the digital outputs from the meter device are fed before recording.

Abstract: 1,075,588. Forming sheet material. O. W. CHRISTENSSON. Sept. 10, 1965 [Oct. 22, 1964], No. 38702/65. Heading B5A. [Also in Division B8] A plastics cover 71, to be heat-drawn on to a plastics-lined container 40, is first heated while remote from the container. The package is supported on a raisable base 46 of a mould which slides within a fixed frame 56. At the stage at which the plastics cover 71 is applied to the top of the support and heated by means of an element 72, the base and mould are at their lowest positions as shown and a vacuum valve 69 is opened to evacuate the inside of the mould and support, thereby drawing the plastics cover partly into the evacuated space. Upon replacement of the heating element 72 by a mandrel (73), Fig. 6 (not shown) the package is raised in the mould under the action of cams (52, 164) to the position of Fig. 6 (not shown) and the mandrel (73) is then lowered to depress the heated cover to a level beneath the level of the edge of the package. Both mandrel and mould are cooled by a flow of coolant through duets (74, 75) and (44, 45). A set of packages may be sealed with a single plastics sheet by an array of such devices, the packages subsequently being separated by cutting away the intermediate parts of sheet between them. In a second embodiment, Fig. 8 (not shown), the heating means and container are separated horizontally. The plastics cover material is supplied in a sheet at (85<SP>11</SP>) to a turret device, which then turns so that the plastics material may be heated at a station (96). At a station (84<SP>11</SP>) the cover is applied to an array of packages, in a similar manner to that of the previous embodiment, and finally at station (95) the sealed packages are delivered on to an output conveyer (93).
