Abstract: 1,194,234. Apparatus for fixing electrostatic images, automatic temperature control systems. RANK XEROX Ltd. Sept. 28, 1967 [Oct. 3, 1966], No.44125/67. Headings G2H and G3R. A developed electrostatic image on a sheet 43 is fixed by heat supplied by an infrared element 68 within a chamber 64. A reflector member 66 is movable perpendicularly to the sheet 43 to control the fusing of the image. A thermostat 84 controls the speed of a blower 79 which supplies air through apertures 75 of a chamber 76 to form an air cushion beneath the member 66. The speed of the blower 79 controls height of the member 66 and thus the temperature. In another embodiment, a reversible motor (97) Fig. 4 (not shown) is controlled by thermostats (98), (99) which are preset for desired high and low temperatures. The motor (97) adjusts the position of member (66) through a chain (92) attached to a sprocket (93). In a further embodiment, the position of member 66 is controlled by bi-metallic strips (85) Fig. 3 (not shown) responsive to the temperature adjacent the sheet (43).

Filed: 1969-09-05
Abstract: 1283708 Tampon making apparatus INTERNATIONAL PLAYTEX CORP 5 Sept 1969 44165/69 Heading A5R A tampon-making apparatus comprises three collinear forming heads, each consisting a ram 80, die 90, mouth 91, a conveying apparatus to feed pairs of pieces of material 28, 23 along intersecting paths towards each forming head and a series of oven cylinders 111 to receive the formed tampons, linked together in a chain which is sequentially advanced by a distance equal to one cylinderseparation through an oven to a stringer and to a station where the tampons are removed and then packaged, the oven cylinders returning back through the oven to the forming heads. The three heads (A, B, C) are spaced apart from each other, by six times the cylinder-separation on the chain, and operate in a three-phase movement. The tampon is made by the material conveyor, laying down pieces 23, 28 at right angles to each other; a ram 80 is pulled down, with plunger 83 extended and forces the material, rayon, into the flared mouth 91, through holes 71, 73 in the material-supporting plates 70, 74. The material is forced on into the bore 90, and then as the plunger 83 is retracted, a series of blades 92 compress the material in a radial direction, through slots 93 in the bore 90. The blades are retracted whilst an outer plunger 82 forces the formed tampon downwards into a waiting empty oven cylinder 111, below the forming head. Under three-phase operation, the head puts a formed tampon in every third oven cylinder. The cylinders then carry the tampons back and forth through the oven to set the tampons in shape and out to a stringer for attachment of a cord. The cylinders carry the tampons to a station where the tampons are removed from the oven cylinders and are packaged into a pair of telescoping tubes which serve as an applicator. The empty oven cylinders return to the forming heads, via the oven.

Abstract: 1,071,627. Measuring thickness electrically. KUHLAUTOMAT VEB. Nov. 10, 1964, No. 45699/64. Heading G1N. A linear dimension gauge comprises a solenoid 1 (Fig. 1) on a core 2 to which an armature 3 is hingedly attached. Extending from the armature is a feeler arm 9, which is brought into contact with for example the surface of a frost deposit on a refrigerator plant to determine the frost thickness. The width of an air gap between the armature and the core end 10, and hence the reluctance of the magnetic circuit of the solenoid, is proportional to the thickness of frost, the armature contacting the core end 10 when there is no deposit. The impedance of the coil is thereby varied when connected to an A. C. supply and the coil may be connected in series with a meter calibrated to indicate frost thickness.

Abstract: 1384569 Copying by scanning MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 9 Oct 1972 [7 Oct 1971] 46448/72 Heading H4F Each line of a document 23 is repetitively scanned by a flying spot scanner 20, the resulting signal from each line scan being processed to provide at the output of flipflop 47 a pulse of duration equal to the duration of the signal due to one black mark or one white space on document 23, which pulse is sampled by clock pulses in AND gate 60, the resulting signal being binary coded at 17 and modulated at 18 for transmission; a correction circuit 70 is included to reduce erroneous operation due to misalignment of successive scans of scanner 20. The clock pulses passed by AND gate 60 are also counted in a binary counter 50 which accumulates the counts corresponding to successive black marks and white spaces, this counter overflowing when all the informaton is one line of the document 23 has been coded, to operate a vertical sync. generator 15 to move document 23 vertically by one line width, for the next line to be scanned. The binary coder 17 also provides a signal to flip-flop 55 at the time when the last digit relating to the mark or space being coded is about to be sent out, each digit sent out occupying one line interval of scanner 20. This "coding completion signal" sets flip-flop 55 to enable AND gate 54 so as to pass clock pulses to a second binary counter 51 which counter has just been cleared by the "coding completion signal". When the count in counter 51 equals that in counter 50, coincidence circuit 53 provides an output, which causes the output of inverter 59 to rise, indicating that the following space or mark is to be coded, thus setting flip-flop 47 to enable AND gate 60, flip-flop 47 being reset by the following pulse of the output of a NAND gate 46 which produces, due to circuits 30, 31, 32, a signal which, when a mark signal is to be coded, is a sampled version of the following space signals (Fig. 80, not shown), and vice versa. If two scans of the same line of the document 23 are not precisely aligned erroneous operation may occur and to eliminate this circuit 70 (also Fig. 7, not shown), is included between NAND gate 46 and flip-flop 47, so that if the error period is smaller than two picture elements it is neglected and if the error period is equal to or larger than two picture elements it is regarded as a mark or space signal of period equal to one picture element.
