Abstract: 1,107,289. Yarn-tensioning device. PALITEX PROJECT CO. G.m.b.H., 24 Oct., 1966 [25 Oct., 1965], No. 47591/66. Heading D1D. A yarn - tensioning device, especially for a 2:1 twisting spindle, comprises a cartridge 10 between upper and lower brake rings 6, 6a, disposed in a hollow hub of a bobbin holder, the lower ring being mounted in a carrier 4a which is displaceablein the direction in which the thread travels and which bears on a spring 13 which is located in a housing constituted by two sleeves 14, 15 one within the other. The arrangement is conained in a housing 1, he lower part of which has provision for renoving the unit consistingof the two slidable sleeves and the spring, so that it can be exchanged for another n which the spring exerts a different force. One arrangement permits the cartridge to be made of ceramic material, and avoids the possibility of the cartridge canting if, for example, a knot should occur in the yarn. The housing 1 is closed at its upper end by a ring 2 slidably mounted on the spindle tube 3. The upper brake ring 6 is carried by a member 4 secured to the tube, and there is a spring 5 between the ring 2 and the member 4. The position of the brake ring in the housing can be adjusted; to this end, the member 4 has a series of slots 8 of different lengths any one of which can be engaged with a member 9 in the housing. The lower brake ring 6a is carried by a member 4a slidably mounted in housing 1 resting on the upper of the two telescopically-arranged sleeves 14, 15 between which is the spring 13, the strength of which is less than that of the spring 15. The upper sleeve is fixed to a spindle-tube 16. So that the unit 13, 14, 15 can be exchanged the lower part of the housing is closed by a threaded cap 17. Alternatively the cap may be attached to the housing by a bayonet joint, Fig. 2, not shown, or by spring clips, Fig. 4 not shown. In Fig. 5, not shown the cap is dispensed with and there is a gap at the bottom of the housing through which the unit can be removed when the sleeves are telescopically compressed. An aperture 12 is provided through which the cartridge can be removed.

Title: Method and apparatus for printing cheques and stacked leaves
Inventor: GELTERMAIR HANS
IPC: B41K3/48
Filed: 1968-10-08
Abstract: 1,247,562. Printing stacked sheets. H. GELTERMAIR. 8 Oct., 1968 [16 Oct., 1967], No. 47608/68. Heading B6C. [Also in Divisions B8 and G5] Books or stacked leaves are printed by a method which comprises causing a printing and stamping device and the stacked leaves to carry out two reciprocating movements relative to each other, one parallel and one perpendicular to the printing plane, wherein the printing is effected in a position corresponding to an end position of each movement whilst in the zone of the other end position of the relative parallel movement, and individual leaves, after printing, are raised by suction and inclined to the printing plane away from the stack so that printing can then take place on the next leaf. General arrangement of apparatus.-A frame 1 carries a printing and stamping mechanism 2 and a horizontally reciprocating carriage 3 which supports a stack of leaves, e.g. a bound cheque book 4. The mechanism 2 includes a vertically reciprocable printing plate 7 and an ink ribbon 8. In use, the top leaf of book 4 is printed in mechanism 2, and the cheque book 4 and carriage 3 is moved horizontally away from under the plate 7; the top leaf is engaged by a suction device 11 which raises the end of the leaf remote from the binding during movement of the carriage back under the plate 7, Fig. 2; the wall 6 of housing 5 for the mechanism 2 guides this top leaf to a vertical position where it is retained by device 12, (Fig. 3, not shown), and the next leaf of the book is printed. In an alternative embodiment (Fig. 11, not shown), the cheque book 4 remains stationary, the printing and stamping mechanism performing both vertical and horizontal movements. Impression mechanism, Fig. 6.-A motor 13 causes carriage 3 to reciprocate under the action of gearing 14, shaft 15, and, on each side of the carriage, sprocket 19, chain 20, follower pin 22 and follower bracket 24. Simultaneously, a reciprocating motion is given to frame 30 by gearing 16, 26, shaft 27, crank wheels 28, 28<SP>1</SP> and connecting rods 29, 29<SP>1</SP>; alternatively, the crank wheels can be replaced by cams (Fig. 6a, not shown). At the topmost position of frame 30, springs 34 are compressed and the drive is disconnected through electromagnetic couplings 31, while pawls 36 lock the frame in this position. When cheque book 4 reaches printing position, the pawls are released, and frame 30 carrying plate 7 is forced downwards for impression by springs 34.

Title: Electric motor speed regulator
Inventor: METZGER LENARD D
IPC: H02P7/29
Filed: 1967-10-20
Abstract: 1,207,161. Automatic control of speed. EASTMAN KODAK CO. Oct.20, 1967 [Oct.27, 1966], No.47868/67. Heading G3R. The speed of a motor 21 is regulated by interrupting its supply when a comparison of pulses whose length represents actual speed with pulses of a constant length, which are initiated by the leading edge of the actual speed pulses, shows that the motor is too fast. Actual speed pulses are produced by a switch 2 or other means coupled to the motor and they trigger a monostable multivibrator Q1, Q2 connected to one input Q3 of an AND gate. A second input Q4 of the AND gate also receives the pulses from switch 2 and the arrangement is such that while both inputs are present the output at C has no effect, but if the speed pulse terminates before the monostable multi-vibrator has re-set (because the motor is too fast) a second monostable multi-vibrator Q5, Q6 is triggered which interrupts the motor supply at a transistor Q7 for a time selected to end before the termination of the next pair of pulses. The time constants of both multi-vibrators, and hence speed, is adjusted by rheostats 12, 22.

Title: Pneumatic tyre low pressure monitoring and warning system
IPC: B60C23/04
Filed: 1972-10-18
Abstract: 1378919 Tyre pressure sensing AVCO CORP 18 Oct 1972 [15 Sept 1972] 47964/72 Heading B7C [Also in Divisions H3-H5] Low tyre pressure warning signals from a wheel mounted transmitter 40, Fig. 2, are received at an antenna 43 fixed to the vehicle, only for a short time each revolution, but are made to last longer by receiver circuitry 45 in order to operate a warning device such as a lamp, bell or a buzzer, 57. There is a transmitter and antenna for each wheel, and the transmitter consists of a pulsed oscillator (Fig. 4, not shown) energized by a battery 41, Fig. 3, when a pressure sensitive switch 37 operates. The switch has a part-spherical resilient member 62 normally held in a dimpled condition by tyre pressure against a rigid support 64. When tyre pressure falls below a certain level, the member 62 touches a contact 72 to connect the battery which is a mercury cadmium battery. The oscillator (40, Fig. 4, not shown) produces r.f. at a frequency determined by a tuned circuit (L86, C85), in bursts whose frequency is determined by a capacitor (100), the frequencies being in the regions 27 MHz and 40 KHz respectively. The r.f. amplifier 54 (Fig. 7, not shown) receives the signals from all the antennas through a summer 53, and has two tuned transistor stages (116, 117). The lower frequency pulse modulation is extracted by a detector 55 (alternative: Fig. 14, not shown), and amplified in a L.F. amplifier 56 which incorporates a diode limiter (152) and an inductive filter (160). Alternative embodiments of the L.F. amplifier (Figs. 15, 19, not shown) use oppositely directed parallel pairs of diodes for limiting, and a third transistor stage. The output pulses of the L.F. amplifier only occur for a portion of each wheel rotation period, and are integrated (at 57, Figs. 10, 16, not shown). The pulse stretching circuit 58 (Figs. 11, 17, not shown) receives the relatively slowly varying integrator output and generates in response to each rise therein, a pulse of predetermined minimum duration. The stretcher circuit is a monostable pair of transistors (173, 174) or may be alternatively a bi-stable complementary pair (Fig. 17, not shown) which responds with hysteresis to different levels of the integrator output. The indicator lamp 47 (Fig. 13, not shown) is energized by the monostable output (179) or the bi-stable output. Alternatively, the lamp may be operated by an S.C.R. (250, Fig. 20, not shown) having a capacitor (252) in the gate circuit and receiving directly the output A of the integrator 57. This capacitor effectively performs the pulse stretching function, and the S.C.R. is turned off when the gate voltage falls by virtue of an oscillating make and break switch (bimetallic) incorporated in the lamps (47M, Fig. 21, not shown). Smoothed voltage supply circuits are described, Figs. 12, 18, not shown.

Title: Yarn tensioning device
Inventor: BARLOW GEORGE EDWARD
IPC: B65H59/16
Filed: 1963-12-05
Abstract: In winding filamentary materials when there are short-term variations in the peripheral speed of the package of the winding-point, the tension is controlled to form packages of uniform tension and low defect level by applying to the yarn an inertial force of \sB 3 gms to \sB 30 gms.  This force may be applied by passing the material over one or more rotary members having a total rotary moment of inertia not exceeding 15 gm. cm2.  Such a member may comprise a disc fixed to which are felt rings between fixed and slidable plates latter being urged towards the adjacent ring by a adjustable spring 15.  In another form, a drum rotatable on a fixed shaft carries a felt disc, the position of the shaft relative to a fixed bearing-surface being adjustable.  Two rotary members as described may be used in combination the axes of the members being relatively inclined.
