Abstract: 1425519 Stereophonic sound reproduction SONY CORP 11 Oct 1973 [13 Oct 1972] 47559/73 Heading H4R In a stereophonic sound reproducing system antiphase difference signals L-R, R-L are fed to left and right loud-speakers respectively, a sum signal L+R to a centre loud-speaker, and normal left and right signals L, R are made available by a matrix at auxiliary output terminals (e.g. for headphone connection), the difference signals being bass-boosted and treblecut in relation to the sum signal by a circuit which may be disconnected, e.g. when headphones are connected to the auxiliary terminals. The arrangement enhances stereophonic separation from closely spaced loud-speakers and reverts to normal stereophony for headphone listening. As shown, L-R signal at input 11 is amplified 3b frequency-adjusted 10 and fed 3c, 13 to left and right speakers SPL and SPR connected in parallel and in antiphase by a polarity inverter 16 for in-phase reproduction of monophonic signals. An L+R signal at input 12 is amplified 4b without frequency adjustment and fed to centre loud-speaker SPM. Insertion of a stereo headphone jack in socket J changes-over the switch contacts to disconnect all three loud-speakers from transformers 13, 14, connect attenuated L, R signals dematrixed by resistors R 10 -R 13  to contacts t 2 , t 3 , and insert circuit 20 or 20<SP>1</SP> in the emitter circuit of preamplifier transistor Q 1  to cancel the frequency adjustment of circuit 10. Alternatively the circuit 10 may be switched out in the socket J. The original sum and difference signals may be derived from disc or tape records or radio broadcast. The bass boost has a maximum between 200 and 400 Hz and the levels of the sum and difference signals coincide at 3-6 kHz, typically 4 kHz.

Abstract: 1,144,281. Extruding nets. DOW CHEMICAL CO. 28 Oct., 1966 [29 Oct., 1965], No. 48426/66. Heading B5A. [Also in Division D1] A net comprising filaments bonded to each other and wherein each filament is composed of at least two synthetic thermoplastic materials intertwined is made by forcing a first material through conduit 18, plenum 15 and passageways 37 and a second material through conduit 21, plenum 17 and passageways 38, the materials being distributed as spiral laminµ within annular passageway 12 upon relative rotation of mandrel 40 and sleeve 27. Using feed block 35, see also Fig. 3 (not reproduced), each filament produced through extrusion orifices 25, 47 has a surface comprised substantially equally of the two materials. Using feed block (35a), Fig. 4 (not shown), the second material, which passes through passageways 38a, forms laminµ with the first material which passes through passageways (37a) and furthermore is encapsulated thereby. With a third form of feed block (35b), Fig. 5 (not shown), a similar result is achieved with the addition of an intermediate layer of the first material. Using the extrusion orifices shown and with rotation of sleeve 27 and/or mandrel 40 the points of intersection of the net are formed when orifices 25 coincide with orifices 47. Alternatively, two distinct sets of orifices may be employed, Fig. 6 (not shown), with the net intersections being formed downstream thereof. With this arrangement and using feed block (35a) the cross-section of the net at an intersection appears as at (65), Fig. 9 (not reproduced). Many suitable combinations of synthetic thermoplastic materials are given, e.g. nylon with polyethylene, nylon with P.V.C., nylon with a blend of polystyrene and butadiene rubber and polystyrene or polypropylene with polyethylene. Preferably one of the materials is orientatable and relatively rigid and the components may vary in colour and/or refractive index as well as in composition. The formed net may be heated and stretched in known manner.

Abstract: 1355657 Control of D.C. motors JOSEPH LUCAS (INDUSTRIES) Ltd 28 Sept 1971 [13 Oct 1970 12 Jan 1971] 48497/70 and 1396/71 Heading H2J [Also in Division E2] A control circuit for a vehicle window lift mechanism comprises a manually operable switch 18 having an off position, a first position in which its movable contact engages a fixed contact 19 and a D.C. motor 17 is driven to lift the window, and a second position in which the movable contact engages fixed contact 21 to reverse the motor to lower the window, a limit switch 24 which closes in the event of an obstruction being placed in the path of movement of the window while it is being lifted, a relay having normally-open contacts 15a, 15b and an operating coil 15 energized by conduction of a transistor 14 and a relay having changeover contacts 16a, 16b and an operating coil 16, the arrangement being such that closure of the switch 24 reverses the direction of operation of the motor 17, even though the switch 18 remains in its first position, and the motor is operated for a predetermined time to lower the window after which it stops until the switch 18 is moved to its off position and then restored to its first position. During lifting the motor 17 is energized through circuit elements 19, 16b, 16a, a resistor 23 being in parallel with its armature. Movement of switch 18 to engage the contact 21 causes the transistor 14 to turn on and energize the coil 15, closure of whose contact 15a energizes the coil 16 to changeover contacts 16a, 16b and so complete the motor supply circuit through circuit elements 15a, 16a, 16b and 15b. Closure of switch 24 also turns on the transistor 14 and rapidly charges a capacitor 27. Members 15, 16 operate as before to reverse the motor 17 until the capacitor 27 has discharged and transistor 14 turns off to de-energize the coil 15, the coil 16 remaining energized through its contact 16a, resistors 23, 25, 26 and contacts 18, 19 to prevent further operation of the motor. The coil 16 is de-energized by movement of the switch 18 to its off position. The switch 24 may be supplied through the switch contacts 18, 19 to ensure that it is only effective during a lifting operation and so prevent inadvertent actuation by other causes from lowering the window and/ or stalling the motor. A control circuit including this modification is described, Fig. 2 (not shown), and includes an RC circuit associated with the switch 24 to ensure that inadvertent movement of the switch 18 to its off position, before the switch 24 has been closed long enough to turn on the transistor 14 and charge the capacitor 27, does not cause mal-operation of the circuit. A diode may be connected in series with the resistor 23, Fig. 2 (not shown) to prevent the motor being stalled with the window open, should pressure be applied to the switch 24 before the switch 18 is moved from its first position, with the pressure then being maintained indefinitely.
