Title: Parallel-to-serial converter for a binary code generator
IPC: H04B14/06
Filed: 1965-10-30
Abstract: In the recoding circuit described in Specification 1,046,792, a set of triggers (T10, T11, T12, T13, Fig. 1, not shown) is so controlled that successive bits of the recoded data are represented by the state of the triggers in corresponding successive time intervals, the states of the triggers outside the intervals being irrelevant. Each trigger 10A, 11A, 12A can either be in an " up " condition throughout its associated sampling interval or can change its condition at the middle of its sampling interval, these two possibilities corresponding to one and zero respectively, so that as shown in Fig. 2 the number 101 is represented. Two methods of converting this representation into serial form are described, namely (a) the output waveforms are combined either singly or in combination with a reference waveform and the resulting wave or waves analysed (b) the output waveforms are re-shaped before combination with a reference waveform. Fig. 2 illustrates method (a). The waveforms are together combined with a reference waveform 13A, the resulting waveform 13B is applied to a diode-capacitor circuit to produce a waveform 13C which is differentiated 13D and shaped to produce a serial output 13E. Outline circuits employing transistors are given.

Title: Method for assembling universal joints
IPC: F16D3/41
Filed: 1967-02-13
Abstract: In a Hooke's type universal joint correct alignment of a spider member 7 and a shaft (2), Fig. 2 (not shown), is obtained during assembly by engaging two opposed journals 17 of the spider with sealing rings 18 in bores 6 in a yokel on the shaft, and positioning the axis Z, Z1 of the other two journals 12 in a plane including the longitudinal axis X, X1 of the shaft by means of a member 8 comprising a support (11), Fig. 6 (not shown), which receives the shaft (2), a plate (13) fast with the support and carrying U- or V-shaped elements 9 engaging the journals 12, and a movable U- or V-shaped clamp jaw (14) also engaging journals 12. Needle cups 20 are then placed on the journals 17, whilst maintaining the above alignment, sliding the sealing rings 18 along the journals to abut shoulders 21. To provide zero, or a slightly negative clearance between the end faces 15, 16 of the journals and the corresponding cups, the arms la, 1b are separated by arms 19 and then released, e.g. by a device as shown in Figs. 11 and 12 of Specification 1,079,602. Retaining elements of the cups are then placed in position. The device 8 is then disengaged and the second yoke is similarly mounted. The method of assembly is particularly applicable to universal joints between a shaft supported in bearings defining its axis of rotation and another shaft supported at one end by the. universal joint and at the other end by a second universal joint. The elements 9 and (14) may be movable about axis X, X4 to obviate the necessity of a close tolerance in the perpendicularity between axis Y, Y1 and Z, Z1 for machining the crossmember.

Title: Thread supply apparatus for textile machinery, particularly circular knitting machines
IPC: D04B15/48
Filed: 1972-06-20
Abstract: To permit ready selective use of thread supply apparatus in textile machines, particularly circular knitting machines, a plurality of support arms, all similar, are clamped to a rail on the machine (which may be a ring for a circular knitting machine). The arms carry projecting rods which extend at right angles to the planes in which drive belts are continuously driven from the machine, to permit selective vertical adjustment of thread supply apparatus to be engaged by selected ones of the drive belts. In one form of the invention, the arms carry two vertical rods, one for idler pulleys around which the drive belts can be looped and the other for the thread supply apparatus itself, so that dismounting and re-mounting of the thread supply apparatus can be eliminated by mere selective engagement of the belts with the thread supply apparatus, or the idler pulleys, respectively, the thread supply apparatus itself being mounted for both vertical as well as radial adjustment on their mounting rods.
Patent ES-404563-A1 (ES)
Title: Vertical convergence circuits utilizing positive feedback for stabilization
IPC: H04N3/16
Filed: 1972-07-05
Abstract: Transformerless vertical deflection circuits often employ negative feedback to linearize its amplifier operation. Where a vertical convergence circuit is coupled in parallel with the vertical deflection yoke, such negative feedback stabilizes the sum of the currents flowing in the deflection yoke and convergence circuit, but undesirably permits adjustments in the convergence current to adversely affect picture height and/or linearity by causing the deflection current to vary in an oppoosite manner. Arrangements are herein described for maintaining the parallel coupling of the vertical convergence circuit with its deflection yoke, but in a manner to eliminate the convergence current from the feeback-loop which then stabilizes the deflection current only.
