Abstract: 812,689. Roller weighting mechanism. NAZIONALE COGNE, S. P. A. April 29, 1955 [April 30, 1954], No. 12551/55. Class 120(2) A device for adjustably applying pressure to and removing pressure from the rollers of a drawing frame is characterized in that the pressure rollers are supported by an arm pivoted on a shaft on which there is also pivoted a pressure applying lever engaging, at its free end, means for effecting angular displacement thereof, there being provided a draw link connecting the lever to the roller supporting arm, whereby the angular displacement of the lever varies the loading pressure of the roller supporting arm. In the arrangement shown pressure roller 1a, 1b are mounted in a pressure applying arm 7 pivoted about an axis 8. Springs 5 transmit the loading pressure to the rollers and the pressure can be adjusted for each roller by a screw 6. A pressure applying lever 9 is also pivotally mounted on the axis 8 and its free end is engaged by a cam 10 fixed on a shaft 11 which can be turned in a manner such as to vary the angular position of the cam. A link 12 is hingedly connected to the arm 9 and its other end hooks around a pin 13 attached to a lever 14 which pivots on the arm 7 such as to form a toggle like mechanism. The shafts 8 and 11 are common to all roller sets of the machine and by rotating the shaft 11 the pressure on all the rollers can be adjusted at once or can be relieved completely. Each set of rollers can be relieved of pressure individually by means of the lever 14 and the rollers are adjustable in position along their respective supporting arms.

Abstract: 1,064,661. Electronic counters. TELEFUNKEN PATENTVERWERTUNGS S G.m.b.H. March 25, 1964 [April 10, 1963], No. 12626/64. Heading G4A. Each stage of a counter has a set and a reset element, each element being fed by an AND gate controlled by one or more of the other elements and in common by the pulse input. A scale-of-6 counter comprises three stages I, II, III each with a set element on the left and a reset element on the right. The pulse input 7 feeds AND gates such as 2 1 , 2<SP>1</SP>1, the other inputs of which come from OR gates such as 3<SP>1</SP> III , 3 III , respectively controlled by the opposite AND gate and opposite element of the preceding stage. The stages I, II, III then set cumulatively to successive pulses and are reset in the same order. In a modification (Fig. 2, not shown) the AND gates receive inputs from appropriate elements of all stages. The AND gates may be followed (Fig. 3, not shown) by pulse-lengthening devices to prevent faulty operation. In a further modification, Fig. 5, the counter operates in a Gray code, only one of AND gates 9-16 opening at any time to an input pulse to switch the associated stage either by setting or resetting as the case may be (according to Table 3, not shown).

Title: Improvements in knife-edged centres for weighing apparatus
IPC: G01G21/08
Filed: 1919-05-20
Abstract: 149,094. Denison, G. H., and Brown, S. C. May 20, 1919. Addition to 132,686. Bearings.-The knife-edged centres of weighing- machines described in the parent Specification are now each made with the sides 5, 7 of the centre parallel to the knife-edge and are secured in the lever by tapered keys 3, 4. As previously, one side of each centre (in this case the left-hand side) is located at a definite distance from the knife-edge so that the distance between the two knife-edges forming a couple is independent of the width of the centres, thereby permitting replacements of the centres without altering the distance between the knife-edges. The faces 5, 7 may be dovetailed to prevent the centres lifting, or the centres may be bolted down. Movement of the centres endways may be prevented by a key on the lever, or by providing lips at the ends of the centres.

Abstract: 595,067. Radio direction-finding. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. July 4, 1944, No. 12767. Convention date, July 30, 1942. [Class 40 (v)] The outputs of the fixed crossed aerials of a direction-finding system are each modulated with the sidebands of a different sub-carrier, itself modulated with a common low frequency and the differently modulated signals are fed to a common amplifier and detector, the respective modulations being separated according to their frequency components and further demodulated to produce two voltages of the common low frequency whose amplitudes are proportional to the aerial outputs and which are fed to the deflecting system of a bearing indicator. Directive aerials 1 and 3 are connected to the signal inputs of balanced modulators 5 and 7, the modulating inputs of which are provided by the outputs from two further balanced modulators 9 and 11 which are fed with carriers of 200 and 500 c.p.s. respectively from oscillators 13 and 15 and a common modulating input of 60 c.p.s. from oscillator 17. The outputs from modulators 9 and 11 consist of sidebands with carrier suppressed as indicated for modulator 9 in Fig. 2. Modulators 5 and 7 also suppress the carrier and if a radio signal frequency of 1000 kc/s. is assumed, the output from modulator 5 which is fed to the input of a receiver 19 will consist of frequencies spaced 140 and 260 cycles above and below the suppressed 1000 kc/s. carrier as indicated in Fig. 2. A similar spectrum, but with spacings of 440 and 560 cycles, will be fed to the receiver from modulator 7. The 1000 kc/s. suppressed carrier is added in the receiver by means of a non-directional aerial input 21 and the demodulated output is fed to band-pass filters 23, 27 which pass the 60 cycle sidebands of the 200 and 500 c.p.s. sub-carriers to demodulators 25 and 29 where the 200 and 500 c.p.s. carriers are resupplied from oscillators 13 and 15. The outputs from demodulators 25 and 29 cornprising 60 c.p.s. voltages of amplitudes proportional to the original 1000 kc/s. signals from aerials 1 and 3 are fed to the orthogonally related field coils of an indicating instrument 31, the moving coil of which is fed directly from the 60 c.p.s. oscillator 17. A band-pass or high-pass filter 33 and amplifier 35 may be provided for the reception of speech signals.

Title: Improvements in and relating to fluid-operated tools
Inventor: BROOKMAN PETER RICHARD
IPC: B23B47/22
Filed: 1950-05-25
Abstract: 695,282. Drilling. BROOKMAN, Ltd., R. S. [May 4, 1951 [May 25, 1950], No. 13103/50. Class 83 (iii). Feed mechanism for use with a fluid-operated tool 2 comprises a piston 12 connected to the tool, a cylinder 11 for mounting the tool, and means for supplying fluidpressure to allow the piston 12 to be advanced or retracted without interrupting the operation of the tool. A drilling unit 1 is attached to the front end of the piston 12 and a compressed-air supply is connected to the cylinder 11 at 8. The pistonrod 9 contains a piston valve 19 engaged by a spring 23 adjacent ports 22 in the rod. The rod 9 also contains a fixed plug 29 engaged by a spring 28 which urges a valve 26 away from its seating 27. The valve 26 is carried on a rod 24. which passes loosely through the valve 19 and a metering screw therein and carries lock-nuts 25. In operation, air passing through the connection 8 rotates the drill in known manner and pushes the piston valve 19 back against its spring to close the ports 22. Air then meters through the valve 19 and forces the piston 12 slowly to the left, thus feeding the drill. The valve 26 is arrested when the nuts 25 engage a member 17 in the cylinder and eventually the seat 27 moves up to the valve and cuts off the pressure supply to the piston 12. The pressure within the piston-rod 9 then becomes balanced on each side of the valve piston 19 and the valve is moved to uncover the ports 22 and allow a spring 14 to withdraw the piston 12 and the tool. The pressure supply to the tool, however, is uninterrupted and maintains the valve 26 in its closed position. Thus the air supply must be switched off before the drill can again be fed into the work. In a modification, retraction of the tool causes a valve 37, Fig. 2, to cut off the air supply to the tool. When the air supply is interrupted, the tool can again be advanced but the tool does not start rotating until the valve 37 is clear of its operating screw 39. The mechanism can also be modified so that the tool is attached to the cylinder and the piston is used as a mounting means.

Title: Improved method and means for doubling yarns
IPC: D01H13/04
Filed: 1942-09-17
Abstract: 562,682. Doubling yarns. BRITISH CELANESE, Ltd. Sept. 17, 1942, No. 13111. Convention date, Sept. 19, 1941. [Class 120 (ii)] Yarns of different twist shrinkage characteristics, i.e. characteristics which affect the shrinkage of the yarns on twisting, are doubled by feeding them at different rates to the feed roll of a twisting and doubling spindle and doubling them with such a degree of twist that the component yarns in the resulting doubled yarn are substantially equal in length. As shown, the yarns A, B are drawn from a creel by the positively driven feed roller 6 of the doubling and twisting spindle and, from a detector arrangement 4, 5, pass around grooves 24, 25 in a wheel 22 rotatably mounted on a shafts 19 to the roller 6 and a grooved idler roll 9 for guiding the yarns several times about the roller 6. The grooves 24, 25 are surfaced with a material having a high coefficient of friction to prevent the yarn slipping therein and the circumference of the groove 25 measured at the bottom thereof is slightly less than that of the groove 24 so that the yarn A of higher twist located in the groove 24 travels faster than the yarn B of lower twist in the groove 25 when the doubling twist given is in the same direction as the twist in the yarn A ; if the doubling twist is in the opposite direction to the twist in the high twist yarn, that yarn is fed at the lower rate. The yarn drawn by the feed roll 6 and running in the groove of smaller circumference drives the wheel 22 and feeds the yarn running in the groove of larger circumference to the feed roll. In modifications, a pair of grooved wheels having grooves of different circumferences, or one or a pair of conical rollers with means for guiding the different yarn to parts of the roller or rollers of different diameters, are used, and the axes of the pair of conical rollers may be inclined to one another at a small angle in planes at right angles to the paths of the yarns.
