Title: Tube bundles for heat exchangers
IPC: F28F21/06
Filed: 1968-10-14
Abstract: 1,237,389. Tubular heat exchangers. E. I. DU PONT DE NEMOURS & CO. 14 Oct., 1968 [19 Oct., 1967], No. 48606/68. Heading F4S. In a heat exchanger comprising a bundle of thin-walled flexible tubes T made of a synthetic plastics composition such as tetrafluorethylene or hexafluorethylene and extending between headers H (only one header being shown), one or more strand elements S are interlaced between the tubes in a regular pattern and so that portions thereof extend through and form transverse flow passages F through the tube bundle. Several such patterns in addition to the one shown, are described. Each strand S has its ends secured in position relative to the tubes so as to maintain in the strand a tension sufficient to keep open the transverse passages F which are formed by portions, e.g. C1, C2, C3, Fig. 1, of the strand passing through the tube assembly. As shown, the strand member is secured by forming it into a double loop around the tube bundle, Fig. 1, and may be further secured by bonding either to itself or to the header H. The strand member or members provide resilient support for the tubes as well as forming the passages F and also permit some bypassing of a transverse fluid flow across the tubes. This is said to prevent compaction and deformation of the tubes by said transversely flowing fluid. The tube bundle may be located in a shell shaped or baffled interiorly to cause mainly a transverse flow of the shell side fluid across the tubes (Figs. 13 and 14). Alternatively (Fig. 12) the tube bundle may be immersed in a fluid container (C1) in which is an agitator (FD) adapted to cause circulation of the container fluid transversely over the tubes. Preferred tube dimensions are given.

Title: Signal-selecting system for a keyboard type electronic musical instrument
IPC: G10H1/22
Filed: 1972-10-23
Abstract: 1406625 Electrophonic musical instruments MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 23 Oct 1972 [25 Oct 1971] 48725/72 Heading G5J An electrophonic musical instrument having keys arranged in octave groups comprises a plurality of tone sources corresponding to one octave, means for detecting the highest or lowest group in which a key is operated and accordingly controlling frequency changing means so that signals from the tone generators will produce sounds of the desired octave and means for detecting the highest or lowest operated key in the group and accordingly selecting the corresponding tone source. The keys of each octave group control switches K 1 -K 12 , K 13 -K 24 , K 25 -K 36 , connected in series chains. When for example a B flat key is operated the corresponding switch changes over to set a B flat bi-stable circuit in memory 1 which opens a diode gate to couple a B flat tone signal from the tone sources 2 to a terminal 20. If more than one switch in the group is actuated, the changeover action of the switches means that only the lowest numbered switch is effective. When a key is operated, the flow of current from source 21 to the memory is detected by detectors 6, 7 and 8 to determine in which octave the operated key lies. If detector 6 detects an operated key in the lowest numbered octave, it closes gates 9 and 10 to render ineffective keys operated in other octaves. Similarly detector 7 will close just gate 10. At the same time detectors 6, 7 and 8 set one or other or neither of memories 11 and 12 to open one or other or neither of gates 13, 14 so that the tone signal at 20 passes through one, neither or both of frequency divideby-two circuits 3, 4 so as to appear at the correct octave pitch at 23. Operation of any key is detected at 22 to reset the previously set bistable circuit in memory 1. In a modification the frequency dividers are replaced by frequency multipliers.
