Patent ES-294582-A1 (ES)
Title: Multilevel vestigial sideband suppressed carrier data transmission system
IPC: H04L27/02
Filed: 1963-12-17
Abstract: In a vestigial side-band data transmission system single frequency control signals are added to the transmitted signal, the receiver including means to derive from the added signals the correct phase of retrieved carrier. Means is also provided at the receiver for establishing the correct threshold in the detector-the system operating on multilevel signals-and to generate clock signals. Prior to transmission of data, carrier is generated which pulls the output toggle of the receiver carrier retrieval circuit to the correct phase. The retrieval circuit, Fig. 2 (not shown), is fed with the received signal and with the output of the demodulator. The output of filter 30 is at twice carrier frequency and inherently reverses phase when the modulation changes polarity. This is fed to carrier threshold detector 37 to enable AND gate 36. This gate provides an output which controls the phase of toggle 33 so that its output, at carrier frequency, is in the correct phase. The system described uses a multi-level signal, and since variation of attenuation in the line could cause errors the threshold levels in the receiver detector are varied correspondingly. The control is derived either by transmitting a continuous signal which has a frequency above the V.S.B. spectrum, variation in this signal level being used to control the threshold levels in the detector, or by using the attenuation of the carrier signal transmitted prior to data (referred to above). In this latter instance a servo loop sets the threshold levels during the reception of that signal. Clock signals introduced at a point following the V.S.B. filter at the transmitter are reconstituted at the receiver for use in the multilevel to binary code converter. Alternatively the clock is derived from the data transitions as described in Specification 1,031,596.

Title: Machines for folding edges of a pliable material,more particularly shoe uppers and the like
IPC: A43D8/44
Filed: 1967-10-31
Abstract: Apparatus 10 for edge folding a flexible workpiece, e.g. a footwear upper 15, comprises a device for making cuts or indentations including a blade 44 and a counterblade 41, drive means for operating the cutting device and control means operable independently of the drive means for controlling cutting operations on the workpiece. The upper 15 slides on a table 14 and its outer edge to be folded runs on a fixed member 16 having an upper surface curved to effect the subsequent edge folding. A presser foot 18 is fixed to a lever 20 pivoted at 21 and connected by a pin and slot connection 23, 24 to a lever 26 pivoted at 27. The other end 28 of the lever 26 is vertically reciprocable, e.g. by a pedal-actuated vertical rod, in a fixed slot 29. A lever 30 pivoted at 31 has a pin 35 adjustably positioned in an abutment 33 thereon. The pin 35 is slidable through a bore 37 in a fixed part 38 of the apparatus and the free end can engage the lever 20. The lever 30 is held against a projection 39 of the part 38 by a spring 73. The counterblade 41 is secured by a pin 42 in a slot 40 in the lever 30 so as to be adjustable towards and away from the presser foot 18. The blade 44 is U-shaped, one prong of the U having a cutting edge 45 and the other prong 46 having a slot 47, and is fixed to the counterblade 41 by a screw 43. The blade 44 and the oounterblade 41 are urged towards each other by a spring (49), Fig. 4 (not shown). The slot 47 is engaged by a pin 50 on a bar 51 fixed to a rod 52 having an enlarged diameter portion 54 having a roller 55 projecting downwardly therefrom and an abutting inclined plane 56 against which a frusto-conical end 57 of a rod 58 is urged by a spring 65. The rod 58 is vertically reciprocable in a fixed sleeve 59 and is pivoted to a rod 61 connected to a box 63 which allows a restricted reciprocation only. The rod 61 is connected to a rod 64 linked to a pedal (not shown). The rod 52 is urged to the left of Fig. 1 by a spring 72 so that when the end 57 is clear of its seating 56, the roller 55 is pressed against a cam 67 keyed to the mainshaft 12 of the machine. In operation, to cut or indent the edge of the upper 15 being folded, the pedal connected to the bar 58 is depressed and the roller 55 follows the cam 67 so that the bar 52 reciprocates the blade 44 through the pin and slot connection 50, 47, the cutting movement of the blade taking place in the same direction as the direction of folding of the edge of the workpiece. Due to the action of the lever 20 on the pin 35 the blade and counterblade assembly are lifted from the upper 15 when the presser foot 18 is lifted and when the foot 18 is lowered this assembly is positioned at a height determined by the projection 39.

Abstract: In a printer having a type disc 11, Fig. 5, formed with selectable relief characters 11a, impression is effected by a pressure roll assembly 20 comprising a shaft 22 loosely bearing a plurality of adjacent resiliently yielding rings 21 urged toward the disc 11 by a roller 26, the arrangement being such that pressure is applied to the image receiving strip 14 only by the rings 21 opposite the raised portions of the character 11a. The force of impression can be varied by turning eccentric rods 31, which support the roller 26, by means of a lever 18. The rings 21 are preferably made of steel. A print operation is initiated by depression of a key 16, Fig. 2, which releases a latch 54 from engagement with a spring clutch 56 to connect a continuously running motor shaft 57 with a worm gear 61 to rotate a cam-shaft 63. A cam 67 on the shaft 63 lifts the roll assembly 20 into a printing position, whereupon a cam 65 reciprocates the assembly 20 through a follower 74, a linkage 75, an arm 76 and brackets 34 connected to the assembly 20 by pin-and-slot connections. After a single revolution of the shaft 63, the clutch disconnects the drive to the worm gear 61 by means of the latch 54, repositioned by a cam 69. Printing is effected through an ink ribbon 15. Paper feed preferably automatically accompanies a print operation and may be to an extent proportional to the size of character printed. In a modification (Fig. 7, not shown), the roller 26 is replaced by a plurality of discs (86) loosely mounted on a shaft (88) and urged toward the rings (81) by leaf-springs (85).

Title: Self priming conductivity cell
IPC: G01N15/12
Filed: 1973-04-25
Abstract: A conductivity cell for use in a system for counting particles suspended in a liquid and operative to reliably and accurately count such particles even in the presence of gas bubbles in the liquid sample. In a counting mode, the cell provides output pulses in response to the passage of particles through a metering aperture, and in a priming mode, the cell is operative to replace a previous liquid sample with a new liquid sample for analysis. During counting operation, gas bubbles which can be present during analysis are collected in a position physically removed from the metering aperture such that these bubbles cannot flow through the aperture during analysis to erroneously affect the particle count. During a priming operation, these bubbles are drawn along with sample fluid from the cell and new sample fluid is infused for a subsequent analytical run. Air is caused to flow through the aperture during a portion of the priming operation in a reverse direction to that of liquid flow during analysis to clear the aperture of any debris which may form during analysis.
