Title: Improvements in or relating to drafting devices for drawing-frames, fly-frames, spinning frames and mules
IPC: D01H5/26
Filed: 1947-11-03
Abstract: 645,066. Drafting apparatus for textile fibres. DELESALLE, C. Nov. 3, 1947. No. 29332. Convention date, Oct. 9, 1946. [Class 120(ii)] A two-zone, double-apron drafting device has the lower feed and intermediate rollers 1, 2 arranged so close together that the distance between the axes is shorter than the average length of the fibres and has the pressure feed roller 3 displaced towards the rear of the lower feed roller 1, in order that the fibres will be held in contact with the latter over a substantial part of its circumference. Additionally, the lower apron 4 is stretched over a convex surface 8, by which at least a third of its fibre-contacting run is supported, and the upper apron 5 is held in contact with the lower apron 4 by means of an adjustable tensioning device, so as to apply substantially uniform pressure to the fibres upon that portion of the lower apron 4 supported by the curved surface 8. The lower apron 4 may be tensioned by a device 7. Condensers 12, 13 may be freely mounted on a traversable supporting member 14, which also carries a sliver guiding and tensioning device 15. Pressure is applied to upper rollers 16, 17 by a resilient hook 18, adjustable by means of a nut 20, or in any other manner. The end of the hook 18 is attached to a saddle 21 by a pressure release lever 22. Two upper rollers 23, 24 and two lower rollers 25, 26 may be employed for cleaning the drafting rollers. When very short fibres have to be controlled, a small, freelymounted pressure roller 27 is arranged to act against the feed roller 1. Feed roller 1 may be driven through a worm from the intermediate roller 2.

Title: Wheel balancers
IPC: G01M1/28
Filed: 1974-07-03
Abstract: 1469592 Detecting vehicle wheel unbalance GKN TRANSMISSIONS Ltd 30 June 1975 [3 July 1974] 29406/74 Heading G1N and G1X The balance of a wheel is tested whilst on a vehicle by means of apparatus comprising a platform on to which the vehicle is driven, jacking means for raising the vehicle, elevatable roller means for engaging the wheel to be tested, motor means for driving the roller means and hence rotate the wheel, means for sensing a rotational out of balance condition and developing a signal in response thereto, and display means responsive to the signal to indicate the condition. The roller means comprises two elevatable rollers 18a, 18b each having associated therewith a respective fixed rotatable roller 19a, 19b, each roller pair 18a, 19a and 18b, 19b forming a cradle for a respective vehicle wheel. Each elevatable roller 18a, 18b is mounted on an elevator member 20a which supports a respective drive member 25a. As described each member 20b is raised by a respective hydraulic ram or piston and cylinder unit 28a and the jacking means comprises an arm 36 having pads 37a, 37b supported from telescopically adjustable bars 38a, 38b, the arm 36 being raised by a jacking ram 40. Rams 40, 28a are connected in a pressure fluid circuit Fig. 5 (not shown) including a pump (41a) and valve means to control the supply of the fluid to the rams. Interlock means prevents raising of the rollers 18a, 18b until fluid-flow has been established to raise the jacking arm 36 and lowering of the arm 36 until the rollers 18a, 18b have been lowered. The sensing means comprises a vibration transducer TDI on a magnetic base 43 which is mounted adjacent the wheel on the chassis. A resulting signal after amplification is rectified and compared with a reference voltage which sets the level of a "pass" or "fail" condition. A voltage is applied to a circuit 49 a pre-set time, as determined by switch 51, after motor 25a or 25b for rollers 18a, 18b respectively has been brought up to full speed, causing a relay RL to be or remain de-energized according to whether the unbalance condition is too severe or not. Relay RL has contacts for energizing "pass" indicator 52, e.g. lamp, "pass" print out device 53 and similar fail indicator 54 and print out device 55. The magnitude of unbalance, rather than a mere "pass" or "fail" indication may be obtained by using in addition a stroboscopic lamp controlled by the output of the transducer TDI to illuminate the wheel under test appropriately marked at its circumference. Measurement of the magnitude of the out of balance signal at the output of amplifier 46 provides data as to the magnitude of a counterbalance weight to be applied, the position thereof being determined by that occupied by the stroboscopically illuminated mark.

Patent GB-346408-A (GB)
IPC: A21D2/36
Filed: 1929-10-01
Abstract: A process of bleaching flour particularly wheat flour comprises subjecting a mixture of flour and a carotin decolorizing or bleaching agent which is solely of vegetable origin to a moderate temperature in the presence of moisture, the bleaching agent being present in an amount, e.g. 1/2 -\ba2/3 per cent of the flour, which is sufficient to effect the desired bleach but is insufficient to impart substantial extraneous flavour to the flour.  The subjection of the flour and admixed bleaching agent to warmth and moisture may conveniently take the form of the usual dough fermentation process in baking.  The bleaching agent may be mixed with the flour at any time after the flour is made.  The bleaching agent may be derived from legumes e.g. soy beans.  The soy beans are partially germinated by steeping in water at approximately room temperature, the beans are then washed and after the wash water has been drained away they are ground to form a sludge and dried in ovens at a temperature not greater than 60 DEG  C.  A corn starch or corn flour or other cereal flour may be mixed with the sludge obtained by grinding the partially germinated beans or with the dried product e.g. in the proportions of not more than one part of soy bean material to two parts of cereal flour.  Alternatively the beans after germination are ground with additional water, the mixture filtered and the filtrate dried at a low temperature and ground to a powder.ALSO:A process of bleaching flour particularly wheat flour comprises subjecting a mixture of flour and a carotin decolourizing or bleaching agent which is solely of vegetable origin to a moderate temperature in the presence of moisture, the bleaching agent being present in an amount, e.g. 1/3-2/3 per cent of the flour, which is sufficient to effect the desired bleach but is insufficient to impart substantial extraneous flavour to the flour.

Title: Improvements in or relating to snap action limit switch mechanisms for switches
IPC: H01H19/18
Filed: 1957-09-23
Abstract: 857,647. Snap-action switches. IGRANIC ELECTRIC CO. Ltd., and TAYLOR, J. R. Dec. 19, 1958 [Sept. 23, 1957], No. 29806/57. Class 38 (5). A switch has an actuating element in contact with two rotatable elements in the paths of indentations formed respectively in the rotatable elements, which are driven at slightly different speeds so that the actuating element is operated periodically only when the indentations reach a given relative position. As shown, the rotatable elements comprise gear-wheels 26, 27, driven by pinions 28, 29, one wheel 26 or 27 having one tooth more than the other so that they move at slightly different speeds. Each wheel 26, 27 carries a cylindrical portion 28A, 29A with a slot 30, and a pin 33 carried by a U-shaped member 31 pivoted at 11 bears on the surfaces of the portions 28A, 29A. The member 31 has surfaces 35 which co-operate with projections 34 on a lever 23 also pivoted at 11. Lever 23 carries an arcuate rod 22 surrounded by a spring 24 acting on pressure-plates 19, 21. Co-operable with plates 19, 21 are ledges 18, 20 on extensions 14, 15, respectively, of toggle links 10, 8 also pivoted at 11. Links 10, 8 are connected at 17, 16 to links 9, 7 coupled at 13, 12 to a plate 1 pivoted at 2 and carrying contacts 3, 4. With the parts in the Fig. 4 position, toggle 9, 10 is overset and toggle 7, 8 collapsed. If wheels 26, 27 are rotated counter-clockwise, slots 30 eventually come into alignment with each other and pin 33 drops into the slots under the bias of spring 24 which bears on the righthand end of lever 23 and, through projections 34 and surfaces 35, on member 31. As wheels 26, 27 rotate, member 31 is rocked clockwise to the Fig. 5 position and the left-hand surface 35 tilts lever 23 clockwise also, and the left-hand end of the lever engages plate 19 and strains spring 24, the right-hand plate 21 bearing on ledge 20 on link 15 trying to straighten toggle 7, 8 and to collapse toggle 9, 10. Eventually, plate 19 is pressed against ledges 38 on link 14 to positively straighten toggle 7, 8, and through abutments 36, 37 collapse toggle 9, 10, each with a snapaction. The contacts are thus changed over and the parts are in the reverse position to Fig. 4. The parts are restored to the Fig. 4 position upon reverse rotation of wheels 26, 27.

Title: An electrically controlled system and automatic machine for repetition work
IPC: G05G21/00
Filed: 1946-10-07
Abstract: 656,172. Controlling lathes, presses, etc.; transferring blanks. VALE, G. M. Oct..7, 1946, No. 29808. [Classes 83 (iii) and 83 (iv)] A control system for a machine tool or the like for carrying out a predetermined sequence of movements for repetition work comprises control means which, through an electrical circuit, controls several eccentrics connected to the machine tool, so that the eccentrics are rotated to predetermined positions in a predetermined sequence, and each eccentric gives a series of intermittent movements to the machine tool and remains locked between the movements. A work-carrying arm 19, Fig. 1, is movable in three directions by rods 5, 6, 7, operated by eccentrics 1, 2, 3 ; the rod 5 rotates a frame 9 about its pivot 8, the rod 6 rotates a shaft 17 supported within the frame 9 and connected by a forked joint 18 to the arm 19 and the rod 7 rotates the arm 19 about its pivot 10. The eccentrics are rotatably mounted on a shaft 27 and are each driven by a belt 26 connected to shafts 22, 23 which are rotatable in opposite directions and.have electromagnetic clutches 24, 25 arranged to slip at a predetermined loading. The shaft 27. has preferably a diameter exceeding twice the eccentricity of the eccentric so that the axis A, B of the rods lies within the bearing diameter, thus providing a self-locking movement. Spring-loaded friction bands 4 attached to the eccentric straps and bearing on the eccentric damp out the momentum of the moving parts. The electromagnetic clutches are controlled by a belt 35, Fig. 4, driven by rollers 36 and having contact studs or holes 46 which complete a circuit through relays 58, 59, Fig. 7, for the clutches, contact bars 43 above the belt, flexible brushes 45 below it and closed contacts 32, 33, 34, Fig. 1. When the required movement is completed, the contacts 32, 33, 34 are opened by a projection 31 on the eccentric. If the contact stud 46 has moved off the bar 43 before the required movement of the work-arm has been completed, it contacts a second contact bar 44 and, through a relay 62, opens the circuit of an electromagnetic clutch 63 in the belt drive so that the belt is stopped and waits on the completion of the movement. In a modification this waiting period is obtained with a single set of contact bars 56, Fig. 6, the belt being driven by a ratchet 64 and a pawl 49 oscillated by an arm 51 and a connecting rod 52, the latter being operated, for example, by one of the shafts 22, 23 ; the control current operates an electromagnet 47 to hold the pawl arm 48 out of the path of the arm 51 until the circuit is broken by the completion of the movement. Brief descriptions are given of the application to a lathe, in which one set of eccentrics controls an arm for supplying and removing work-pieces and a further set are connected by flexible cables to the chuck controls and to the lathe starting control, and of the application to supplying blanks to a power press.
