IPC: D02G1/12
Abstract: 1,051,721. Crimping yarns. KLINGER MANUFACTURING CO. Ltd. Feb. 26, 1963 [Nov. 29, 1961 (2); April 4, 1962]. No. 42726/ 61, 42728/61 and 44135/62. Divided out of 1,035,935. Heading D1F. Yarn, e.g. of polyhexanethylene adipamide. polyethylene terephthalate, or polypropylene, is "bunched" i.e. crimped by compressing it in the direction of its length, by tensioning the yarn when subjected to heat and then passing it through a crimping zone where it is again heated whilst and/or after being crimped. The tensioning may be such as to stretch or permit a controlled shrinkage of the yarn. A bunching zone may be bounded by a part of the periphery of a rotating wheel which impedes the yarn travel so that the bunched yarn clings to the wheel and moves with it out of the zone: the yarn is enclosed as it extends around the wheel and is heated thereat. In the apparatus of Figs. 3 and 4 (not shown) yarn drawn from bobbin 62 by rollers 63 passes over an arcuate surface 64 (controllably heated by an electrical element 65) on which the yarn is guided e.g. on a zig-zag path, to make successive passages. If yarn shrinkage is to be allowed, rollers 63 may be omitted. Rollers 19, which may rotate at the same (or higher) peripheral speed as rollers 63, advance the yarn into a groove 12 in an arcuate element 10 through a hole 21 in a wedge-shaped portion 18 thereof. Groove 12 is closed at one end by a plate 71 and is slotted to receive a toothed or serrated edge of a wheel 14 rotating at a peripheral speed many e.g. 120-460, times slower than rollers 19 to retard and move with the bunching yarn. Crimped yarn emerging at the open end of the groove is withdrawn through a tensioner and wound. In a modification, Figs. 1 and 2 (not shown) element 10 is slotted at 20 to accommodate partially the periphery of rollers 19 9 and the wedge-shaped bottom of the slot is bounded by arcuate faces 17 and enters the bight of the rollers. Element 10 has arcuate grooves 11 accommodating electric heating elements (not shown) and the edge of wheel 14 projects through a mouth 13 into groove 12 to which yarn is fed through a hole 21. A yarn guide block 73, rollers 19 and/or wheel 14 may incorporate electric heating elements and all heaters may be thermostatically controlled. Drives for all rotating parts of the apparatus. including winding mechanism 69, are derived from a single motor 59 and transmitted through chains and sprockets, spur gears and a reduction gear box.

Abstract: 1098457 Counters ASSOCIATED ELECTRICAL INDUSTRIES Ltd 21 April 1965 [21 April 1964] 16489/64 Headings G4D D6Y D1D9G D1D14 D6C1 and D6C2 The inputs to a reversible counter are preceded by a buffer circuit which eliminates coincident overlapping or alternating forward and backwardstepping pulses. Forward X or backward Y pulses pass along paths Ml, M4, A2, A4, A6 or M2, M5, A3, A5, A7, as the case may be to advance or reverse the counter. If two pulses coincide AND gate Al operates trigger M3 to inhibit A2, A3 so deleting these pulses. The delay from M3 is such as also to delete overlapping pulses. Bi-stable device is set or reset by pulses from A2 or A3 so as to inhibit AS or A4, respectively. Alternate X and Y pulses are thus eliminated, two pulses of one type being necessary to pass A4 or A5. A further bi-stable device BS2 may be provided.

Abstract: 1,225,879. Disc brakes. DR.-ING. h.c.F. PORSCHE K.G. 24 Oct., 1969 [9 Nov., 1968], No. 52206/69. Headings F2E and F2F. A servo-brake mechanism for disc brake units, especially for dual cycle disc brake units of automobiles, comprising means 5 adapted to be actuated by the vehicle operator for operation of the disc brake units, a brake master cylinder 1 having a master piston 7 and at least one pressure piston 11 displaceably associated therewith, said master piston being connected with said actuation means, at least one brake caliper 3 associated with at least one brake disc 4, brake lining brackets 34, 34<SP>1</SP> associated with said brake caliper, first conduit means connecting said brake master cylinder and said brake caliper, whereby upon actuating said actuation means, said brake lining brackets are brought into engagement with said brake disc with the resulting braking moment being utilized for amplifying the braking power, and means for amplifying the braking power of said pressure piston independently of said first conduit means, said amplifying means being associated with said brake caliper and said brake lining brackets being held in the direction of rotation of said brake disc with a degree of play and being operatively associated with said amplifying means. As shown, actuation of brake pedal 5 displaces piston 7 and pressure pistons 11, 11<SP>1</SP>, whereby fluid pressure in chambers 13, 13<SP>1</SP> is conveyed to wheel cylinders 2 via dual conduits 14, 14<SP>1</SP> and so that brake linings 33, 33<SP>1</SP> engage the brake discs 4, the lining brackets being provided with slots 35 so as to be displaceable on a U-shaped clip 37 carried by the brake caliper 3. The pads, during braking, are moved toward servo-pistons 26, 26<SP>1</SP> and against the loading of springs 27, 27<SP>1</SP> whereby pressure fluid is displaced from the cylinders 20, 20<SP>1</SP> through conduit 19 and to pressure chamber 18 of the master cylinder; the area of the piston 11 is greater than that of the piston 7 so that the pressure increase is conveyed to the driver actuating the pedal 5. In emergency braking, when the amplifying power of the pistons 26, 26<SP>1</SP> becomes too high, the volume of the chamber 18 is increased by the volume of an equalization chamber 23 through overloading of a valve 24. The chamber 18 is connected via a valve 21 to a pressure fluid storage tank 17 which is also connected to the chambers 13, 13<SP>1</SP>.

Abstract: 1,226,157. Magnetic memory apparatus. THOMSON CSF. 26 March, 1968 [4 April, 1967], No. 14573/68. Heading H3B. In a waffle iron memory read pulses have the same polarity as write pulses, whereby non- destructive read-out may be obtained. Conductors 5, 7 lie in grooves 2 in a soft magnetic substrate, the assembly being covered by a sheet of rectangular hysteresis loop material (not shown). Data is stored at the intersections MNPQ of the two looped conductors. To write data, a positive word pulse is supplied to conductor 5 simultaneously with a positive or negative digit pulse supplied to conductor 7. At intersection M the flux pattern of Fig. 3 is produced for a positive digit pulse (1), the pattern for a negative pulse (0) being similar except that the vectors directed to the right in Fig. 3 are directed at similar angles to the left. If a positive read pulse is then supplied to conductor 5 the pattern of Fig. 6 is produced if a 1 was previously written. The flux at point M at the centre of the intersection is switched from direction Z to a direction parallel to conductor 7, and in addition there is a reversible flux rotation at points u. A negative pulse is thereby generated in conductor 7. When the read pulse is removed the fluxes at u fall back almost parallel to conductor 5. Subsequent read pulses repeat the reversible flux rotations alone, the resulting output pulses being of smaller amplitude than the first but of the same polarity. Similarly the first interrogation of a O produces a large positive output pulse and subsequent interrogations produce smaller ones. Preferably each word pulse is preceded by a negative erase pulse, the digit pulse having a duration covering both pulses on the word line. In Fig. 12 (not shown), two similar memories are supplied in parallel from a common digit pulse generator and their outputs are taken to a common amplifier. It is stated that parasitic effects during write-in are thereby reduced.

Abstract: 1,227,774. Controlling the discharge of sweets from endless conveyers. UKRAINSKY NAUCHNO - ISSLEDOVATELSKY I KONSTRUKTORSKY INSTITUT PRODOVOLSTVENNOGO MASHINOSTROENIA. 3 May, 1968, No. 21101/68. Heading B8A. A member 2 adapted to discharge a sweet X in the direction of arrow A from an endless conveyer belt 1 is blocked from moving if the sweet X does not sufficiently complete its travel on the conveyer. The sweet X normally abuts a feeler 13 and moves this into engagement with a stop 22. This causes anticlockwise (as seen in Fig. 1) rotation of an arm 15. A comb member 10 carried by the latter is thus moved out of blocking relation with a member 9 carried by the pusher 2. The latter is thus able to move under the action of a spring 8 as permitted by a cam 6. Another spring-urged cam-controlled member 23 carries a wedge-shaped member 24. This will normally pass between a member 14 carried by the feeler 13 and a surface 20. If however the feeler has not been sufficiently deflected by the sweet X, the wedge surface of the member 24 engages a correspondingly inclined surface on the end of the member 14 and thus rotates the feeler in a direction opposite to normal and hence the blocking member 17 is moved into a more positive blocking position. In a modification (Fig. 3, not shown) the member 14 is carried by the member 17.

Abstract: 1,267,141. Driving fasteners. SWINGLINE Inc. 4 June 1970 [23 July, 1969], No. 26909/70. Heading B4C. A fastener driving machine comprises a housing 13, a reciprocable piston 14, fastenerdriving means 17 connected to the piston 14, air pressure means for actuating the piston 14, bumper means 20, e.g. of rubber, an air return chamber 29 for allowing the piston 14 to return at the end of a working stroke, and air passage means 23 leading from the housing 13 below the level at which the return stroke of the piston 14 commences after striking the bumper 20, but above the end of the piston stroke in the absence of the action of the bumper 20. With the machine at rest, compressed air from an inlet 40 acts, through valve ports 42a, 52 and a conduit 41, on a poppet valve member 30, and fills a chamber 39. On positioning the machine against a workpiece, a probe (not shown) engages the workpiece, raising a link 49 pivoted thereto at 50 to render a hand trigger 47 operable. On actuating the trigger 47, a fluted plunger 43 is raised against a spring 45, Fig. 2A, an 0-ring 44 blocking flow to the port 52, while compressed air from a chamber 31 above the valve member 30 escapes to atmosphere along the flutes 46 of the plunger 43. The valve member 30 is then raised against a spring 34 by the pressure in the chamber 39, an outlet 32 being blocked by a sealing insert 35. Pressure thus impinging on the piston 14 then actuates the driving means 17 to drive a fastener 27 from a magazine 26 into the workpiece. Air above the piston enters the air return chamber 29 through opening 23 as the bumper 20 is compressed by impingement of the piston, whereupon the piston 14 rebounds to lie above the level of the openings 23, so that the pressure built up in the chamber 29 acts on the underside of the piston 14. On releasing the trigger 47, the plunger 43 is urged downwardly, restoring compressed air flow to the chamber 31, so that the member 30 returns to its initial position, air above the piston exhausting through the outlet 32 and an opening 36 while the pressure in the chamber 29 returns the piston 14 to operable position. In the absence of the action of the bumper 20, e.g. owing to damage thereof, the piston 14 comes to rest after the operative stroke with the openings 23 above its upper surface, so that on release of the trigger 47, the pressure in the chamber 29 exhausts through the openings 32, 36 and the piston 14 does not return to its operable position.
