Filed: 1975-12-23
Abstract: 1504180 Detecting flaws electrically NIPPON KOKAN KK 23 Dec 1975 [27 Dec 1974] 52705/75 Heading G1N In an inductive type flaw or weld detector of the type in which the metallic object to be tested is moved sequentially past two series connected inductance coils the coils are connected in the feedback path of an amplifier. The A.C. output from one terminal of oscillator 3, the other terminal of which is connected to ground, is connected to one input of amplifier 4F provided with two sensing coils 21, 22 connected as shown between the amplifier output, the second input of the amplifier and ground. If the object 1 being tested is homogeneous then as it moves in the direction of the arrow the impedances of the coils 21, 22 remain substantially equal to one another and the feedback ratio of the amplifier remains at its normal value. If the object 1 includes a weld seam 5 then as it approaches coil S 2  the impedance thereof gradually increases and reaches a maximum when it is opposite the coil. At this time the amplification factor of the amplifier has fallen to a minimum so that the output of synchronous detector has fallen to a minimum. As the seam S then approaches coil Si its impedance increases and reaches a maximum and since the impedance of coil S 2  at this time has returned to its normal value the amplification factor is a maximum. Thus the detector output is a maximum, and the presence of a flaw may be detected by noting the change from a positive to negative of the detector output, the point of inversion being substantially independent of variations in distance 1, Fig.4 (not shown). The width of a plate may be detected by replacing each coil by a series of coils extending across the plate, the series being arranged in parallel, Fig. 5 (not shown).

Abstract: 1,128,250. Measuring air leakage electrically. R.J. REYNOLDS TOBACCO CO. Dec. 16, 1966 [Jan. 20, 1966], No.56527/66. Heading G1N. [Also in Division A2] In an apparatus of the type in which cigarettes are tested for leaks by subjecting the interior of a cigarette to air under pressure different from the pressure outside the cigarette, said air being supplied through retractable tube means mounted in one end plate of a rotating cigarette-transporting suction drum, and variations in air flow caused by leaks in a cigarette are sensed, the sensing means comprises a heated wire of substantial temperature coefficient of resistance connected to one leg of a conventional bridge circuit, and the out of balance current is amplified and applied to a relay that actuates a cigarette rejection mechanism. In one embodiment, air flows through the cigarette from one end to the other, in the absence of leaks, and thence passes first through a filter and then through the hot wire sensor to atmosphere. Ejection of faulty cigarettes is effected by air pressure, while normal cigarettes are retained on the drum by suction. In another embodiment, air at constant pressure is passed first over the sensor housed in the common (upright) leg of a "T" branched conduit and is then fed via the other two legs of the conduit to both ends of the cigarette to be tested, little or no air flowing in the absence of leaks. In a modification of the latter embodiment, the common conduit includes a throttle and beyond this a branch conduit leading via the sensor to atmosphere.

Title: Optical disc drive for organ
IPC: G10H3/06
Filed: 1971-12-10
Abstract: 1314780 Electrophonic musical instruments MATTEL Inc 10 Dec 1971 [10 Dec 1970] 57383/71 Heading G5J An electronic organ utilizing a disc record comprises a housing containing disc supporting means, including a spindle, and disc driving means in the form of a drive wheel and backup roller which grip the record at its rim, means, comprising a disc lifting member to guide the record over the spindle and a mechanism to space the drive wheel from the backup roller and drive shaft of the motor, being provided such that a record may be easily inserted into the organ. A door 26, Fig. 6, at the front of the housing pivots about an axis 70 and when open, as shown, causes a lever 56 to rotate such that the disc lifting member 54 moves in the direction of the arrow 72. This causes a portion 74 of the member 54 to slide up a ramp 76 in the base 40 of the housing which results in a section 78 being raised above the level of the base. One end 80 of the member 54 remains in contact with the base 40 such that an upwardly inclined ramp is formed and the disc may be guided over the spindle. The lever 56 also controls a linkage 92 which causes the axle 86, on which the drive wheel 48 is mounted, to move downwardly and laterally from the back up roller 50 and drive shaft 82 of the motor in order that the rim of the disc may be inserted. Upon closing the door 26 the lever 56 rotates in the reverse direction causing the disc lifting member 54 to fall to its original position and causing the axle 86 to be urged back into contact with the rim of the disc and the drive shaft 82 by means of a spring (not shown). Upon insertion, the disc is also guided beneath a pick-up head by means of inclined ramps on the housing and on the head itself and, once inserted, is kept in close contact with the head by means of two rollers mounted on resilient axles. The side and back walls of the housing allow for a small clearance from the record, this clearance being less than the radius of the spindle such that when the record is inserted and the door is closed the hole in the record is always sufficiently aligned with the tapered tip of the spindle to cause the record to fall on to the spindle. An on-off switch, which also moves the axle of the drive wheel away from the drive shaft and disc, is incorporated and comprises a linkage system ending in a hook 124 which engages the axle 86. Upon opening the door of the housing or operating the on-off switch the axle 86 moves away from an operating member 128 of a switch 126 such that the switch 126 opens and the supply to the motor 84 is cut off. Additionally, the speed at which the disc record is rotated may be varied by means of a screw control on the housing which moves a bracket, to which the motor is attached backwards and forwards such that a different diameter of the drive shaft 82 contacts the drive wheel 48. In an alternative embodiment, Fig. 11 (not shown), a door operated linkage retracts the central spindle when the door is opened to insert a disc.

Abstract: 1,110,169. Zig-zag folded electrode assemblies. VARTA A.G. 23 Dec., 1966 [29 Dec., 1965], No. 57791/66. Heading H1B. In an accumulator electrode assembly the plates of one polarity (1), before folding, are in the form of a chain of rectangular plates electrically connected each to the next along, or close to, one side of the chain by short webs (4) permitting the plates to be folded in a zigzag manner to become parallel to each other, the said plates being enclosed by a U-section continuous separator (3), and the plates of the other polarity (2) being similarly electrically connected in one or more chains along, or close to, one side of the chain, and interleaved with the plates of the enclosed chain by zig-zag folding of the assembled plates. The plates of the uncovered chain may lie in contact with one arm only of the separator or may be disposed on either side of the enclosed plate chain in any desired sequence, e.g. alternatively, as in Figs. 1-3. There may be two uncovered chains, both on one side of the covered chain, or one on each side. The chains of opposite polarity may be vertically staggered so that each plate in part has no counter-electrode. After the first zig-zag folding, a fold at or near the middle of the assembly may be folded back so as to reverse the sense of the fold, so bringing the plates originally at the ends of the assembly together in the middle, while the plates adjacent the fold become the new end plates. The plate chain of one polarity may have an additional plate at one end, which is folded back into one of the folds of the assembly.
