Title: Electrical tuner
IPC: H03J5/30
Filed: 1974-09-27
Abstract: 1477400 Turret tuner OAK INDUSTRIES Inc 27 Sept 1974 [9 Nov 1973] 42125/74 Heading H3Q [Also in Division F2] In a tuner having a housing (10, Figs. 1 and 2, not shown) and a rotary channel selector shaft 12, Fig. 10, coil strips 60 each having a fine tuning screw 92 and axially spaced contact members 64 are mounted on the shaft and cantilever spring contact members 82, Fig. 4 which are secured at one end, each have a length between its secured end and the point of contact with contact member 64 of a selected coil strip greater than the distance between the axis of the shaft and that point of contact. As disclosed the contact springs 82 are riveted to a printed circuit board 80. Each tuning screw 92 is retained by resilient arms 100, Fig. 12, within a tapered slot 106 of an oscillator screw retainer 30 which can be of plastics so as to provide an inward bias to the screw and prevent backlash. The right-hand ends of the coil strips 60 have projections (83, Fig. 13, not shown) which clip into grooves (81) in resilient arms (74) of a plastics rotor disc strip retainer 32 so as to locate the coil strips in slots 76 in the retainer 32. The left-hand ends of the coil strips are located in holes (68, Fig. 9, not shown) of a rotor strip retainer spring (50, Fig. 6, not shown). The retainers 30, 32 and (50), an electrical shield (46) and a detent wheel (56) are located on different flat portions (34a, 34b, 28a, 28b; 54a, 54b, 42a, 42b and 54a, 54b, Figs. 14 and 15, not shown) respectively of the shaft 12. Fine tuning.-A return spring 130, Fig. 10, normally retains a pinion gear 110 in the dotted position so that gear surface 112 is out of engagement with the fine adjusting screw head 94. Rotation of a fine tuning drive gear 24 rotates the pinion gear 110 and a tight fitting clutch spring 122. As the ends (126, 128, Fig. 11, not shown) of the spring 122 are in contact with a bracket 114, the spring 122 creates a force overcoming that of the return spring 130 to move the pinion gear 110 to the full line position. Further rotation of the fine tuning drive gear 24 then causes the adjusting screw 92 to be rotated via the pinion gear surface 112 driving head 94.

Title: Novel unsaturated ethers and a process for the manufacture and conversion thereof
Filed: 1959-12-11
Abstract: The invention comprises ethers of formulae:  <FORM:0871277/IV (b)/1> and <FORM:0871277/IV (b)/2> wherein each R represents an alkyl group containing up to six carbon atoms, the dotted lines indicating that the R groups are optional and, in particular, 6:10-dimethyl-2:2:4-triethoxy-undecadiene-(5:9), 6:9:10-trimethyl2:2:4-triethoxy-undecadiene-(5:9), 3:6:10-trimethyl-2:2:4-triethoxy-undecadiene-(5,9) and 6:10-dimethyl-2-ethoxyundecatetraene-(2:4: 6:9).  The ethers may be cyclised to alpha- or beta-ionone or homologues thereof.  They are prepared by acetalising citral or a homologue thereof, condensing the acetal with a 2-alkoxypropen-(1) or a 1- or 3-mono- or 1:3-di-alkyl derivative and, if desired, heating the resultant tri-ether in the presence of an acidic material to remove two molecules of alcohol to give the mono-ether.  In Examples: (1) citral is reacted with ethyl orthoformate in alcohol solution in the presence of orthophosphoric acid to give citral acetal, which is reacted with 2-ethoxypropene-(1) in a solution of zinc chloride in ethyl acetate to give 6:10-dimethyl-2:2:4-triethoxy-undecadiene-(5,9), the tri-ether is dissolved in benzene together with p-toluenesulphonic acid, quinoline and hydroquinone and the mixture heated to give 6:10-dimethyl2-ethoxy-undecatetraene-(2:4:6:9) which is finally cyclised with phosphoric acid to alphaionone; (2) by the process of (1) e -methylcitral gives (6:9:10-trimethyl-2:2:4-triethoxyundecadiene-(5,9) and alpha-irone; (3) citral acetal is condensed with 2-ethoxy-butene-(2) by the process of (1) to give 3:6:10-trimethyl2:2:4-triethoxy-undecadiene-(5,9) which is treated further as in (1) to give 3:6:10-trimethyl-2-ethoxy-undecatetraene-(2:4:6:9) and isomethyl-alpha-ionone; (4) as in (3) but carrying out the de-alcoholation step in the presence of orthophosphoric acid and hydroquinone.

Patent GB-1359316-A (GB)
Title: Shift register circuit
IPC: G11C19/04
Filed: 1971-09-13
Abstract: 1359316 Relay shift registers TSUBAKIMOTO CHAIN CO 13 Sept 1971 [11 March 1971] 42516/71 Heading G4B Each stage of a shift register comprises a magnetic latch relay LR, Fig. 1, a capacitor C, and a change-over switch SM connected as shown to buses 1-3 which are maintained at reference, 2E and E potentials respectively, the capacitors being normally charged to 2E. When a shift relay S is energized, contacts SM0-SM3 are changed over and the capacitors C are discharged through the relays LR, but since the current flows in the reset direction, no other change occurs when the register is empty as shown. If a binary 1 is entered in the first stage by actuation of switch P to discharge CO, subsequent actuation of the shift relay S will cause current flow through LR1 in the set direction so that contact LRM1 changes over and C1 will remain discharged after return of the shift contacts SM to the normal position. Subsequent actuations of the shift relay S cause progression of the binary 1 through successive stages. Read-out may be obtained from loads 7. The circuit may be adapted for use in an automatic shift register which may store more than one bit in each stage, as shown in Fig. 2, wherein each stage includes a relay LR for each bit, with corresponding capacitors C and changeover contacts S. If two bits including at least one binary 1 are entered into the first stage by contacts 20A, 21A, the presence of the 1 bit(s) cause(s) energization of a relay Q10 over LRM11-2 and/or LRM12-2, and, on actuation of a switch 22, a shift relay S10 is energized, followed by a relay T10 which then holds over Q10B and T10A. Relay S10 operates contacts S10A, S10B to transfer the two bits from stage 1 to stage 2 whereupon similar actuation of relays Q20 S20 and T20 takes place, and relay S10 in the first stage is then released (Q20C), reset current is supplied to LR11 and LR12 and Q10, T10 are released. Similar operations occur in the successive stages until the two bits reach the last empty stage. The circuit of Fig. 1 may also be modified to form a shift register in which each stage has its own individually controlled shift relay, Fig. 3 (not shown). The shift relays may, for example, be actuated in succession as an article on a conveyer enters successive sections so that a binary code identifying the article is stepped through the register in synchronism with movement of the article along the conveyer.

Title: Automatic switching device for evr players
IPC: H04N5/84
Filed: 1972-09-22
Abstract: 1380485 Television MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 22 Sept 1972 [23 Sept 1971] 43990/72 Heading H4F  In an EVR player an automatic switching arrangement is provided which ensures that a colour picture is reproduced if luminance and chroma information are recorded on the two tracks A and B respectively of the EVR film irrespective of the position of the channel selector switch 30 which is used to select one of the tracks when different monochromatic video programmes are recorded thereon. The switching arrangement includes three switches 27, 28 and 29 controlled via drive circuit 32 by the output of a pilot detector 26 which detects the presence of a 0À9 MHz pilot signal superimposed on the 1À8 MHz quadrature modulated chroma subcarrier signal channel. If this pilot signal is detected, i.e. colour information is being reproduced, switch 29 is switched off and switches 27 and 28 on. Instead of detecting the pilot signal the 1À8 MHz subcarrier may be detected. To display a colour coded striped test pattern a switch 31 is provided so that the pilot detector may be rendered inoperative. If a monochromatic film is being played and track A is selected, the signal from track B is also reproduced, and although this contains only monochromatic information it may contain a large amplitude component at or around 0À9 MHz which would actuate pilot detector 26 and thus cause the brightness signal from track B to pass to the chroma processing circuit and be displayed as noise. To prevent this happening a detector 33 is provided which detects any signal outside the frequency band 0À9-2À3 MHz, e.g. a 0À1-0À5 MHz bandpass filter, and in response thereto actuates gate 34 to block any signal from pilot detector 26. A complete EVR player system is described with reference to Fig. 8 (not shown) in which a 3À58 MHz NTSC chroma signal is produced, the system including a chroma killer and burst killer.
