Title: Improvements in yarn winding and twisting machines
IPC: D01H13/18
Filed: 1952-07-15
Abstract: 723,269. Yarn detector mechanism. SCRAGG, Ltd., S. & E., and SCRAGG, F. Sept. 16, 1953 [July 15, 1952], No. 17782/52. Class 120 (2). Yarn detector mechanism for a yarn winding and twisting machine of the kind in which the spindle is driven by a belt, comprises a yarn guide on the upper end of a substantially vertical pivoted arm having a weighted tail which falls when the yarn passing through the guide breaks or fails, to effect the withdrawal of the spindle from its driving belt and an arm carried by a counterweighted lever which is normally held in an inoperative position by a locking member and adapted when released by the locking member to engage under the tail and lift the latter to move the yarn guide into a convenient position for threading up. As shown yarn guides 1 are mounted on the upper end of an arm 2 pivoted on a horizontal axle 3 and are each provided with a weighted tail 5. Yarns 6 drawn through the guides 1 normally hold the arms 2, &c. in the position shown in Fig. 1. When a yarn 6 breaks or fails the associated weighted tail falls and this movement is used to operate a stop motion as described in Specification 723,154. In order to re-thread the yarn guide 1 a lever 7 pivoted on the bracket 4 is provided. This lever 7 has an extension 8 disposed under the weighted tail 5 and is counterweighted so that if free to move, the extension 8 will move into engagement with the tails 5 and hold them and consequently the guides 1 in a position for threading up as shown in Fig. 3. A lever 9 pivoted on the bracket 4 is associated with lever 7 or the extension 8 thereof and is adapted to hold the extension 8 in the inoperative position shown in Fig. 1, or release it when re-threading of any of the guides 1 is necessary. After re-threading the lever 9 is turned to move the extension 8 into and hold it in its inoperative position. When used for wet doubling the lever 7 is provided with a forwardly projecting arm 10 carrying a yarn guiding roller 11, which operates in conjunction with a trough 12.

Abstract: 793,056. Screw-cutting tools ; turning. STROBEL, H. June 20, 1955, No. 17796/55. Class 83 (3). A tool for cutting internal or external screwthreads comprises a cylindrical threadedportion and a conical entry-portion, in which the teeth 4 in the entry-portion are of equal pitch 14 and equal depth, with their rear flanks 10 parallel, in longitudinal section of the tool, and inclined and shorter relatively to the rear blanks 13 of teeth 5, so that, measured parallel to the tool-axis, the roots 8 of the teeth 4 are mid-way between their crests 7 and their pitch is equal to that of the teeth 5. The teeth in the entry-portions of the cutting-elements 24, Fig. 4, for a built-up die are machined in a holder 25 rotated by a motor 33 and fed by a cam 26 on the holder, which is pressed by a spring 30 against a stationary pin 27, the spring acting on a collar 31 on the holder-shaft 28, which is movable axially relatively to the motorshaft 34. A cutting-tool 35 is fed radially, against the influence of a spring 41, by a pushrod 39 and a cam 40 rotated through gearing 45 from the motor 33. The cam 40 has a control surface for each element 24 and besides facilitating the conical shaping of the entry portion, also provides radial-relief behind the leading- edges of the elements, while the cam 26 is stepped at the ends of its spiral-surface to return the holder,-after each rotation, through a distance equal to the pitch of the teeth. The rod 39 is screw-threaded to engage a carriage 37 supporting the tool-holder 36 and adjusts the depth of cut.

Title: Improvements in and relating to the manufacture of rubber-tyred wheels, buffers or other articles having a peripheral cushioning ring or arc
IPC: B29C37/00
Filed: 1947-07-07
Abstract: 647,141. Vehicle wheels. MAWBY, R., and HOLT, A. C. July 7, 1947, No. 17852. [Class 144 (i)] [Also in Groups V and XXII] A moulded rubbertyred wheel comprises a tyre 2, Fig. 2, and a disc part 1 having a central boss 3 and a well base rim or rim of channel-section4. The disc 1 is moulded or cast from a low-melting- point zinc alloy metal or from a plastic material, and may incorporate a bearing-bush 11. The tyre 2, Fig. 3, has circumferentially-recessed walls 7 pierced by lateral holes 8, and may have integral pips 23 for positioning the tyre in a mould. In the process of moulding, the metal or plastic material is cast or injected around the tyre to form the disc 1. By this means the material is caused to flow through the holes 8 and form bars 9 which connect and brace together the flanges or side walls 6 of the rim 4, effectively locking the tyre and disc together. In Fig. 6, the tyre is not circumferentially recessed, so that the walls 6 stand proud. If desired, beads or flanges 10, Fig. 5, may be formed to reinforce and key the tyre 2 to the rim in addition to the bars 9. Another form of interengaging means between tyre and disc is described, Fig. 7 (not shown), and the disc may be formed with radial spokes or the like. In the case of large and heavy wheels the tyre may have a square shaped tread portion. The holes 8 may be rectangular or oval.

Title: Improvements in or relating to detecting and measuring registration errors of patterns of work on a moving web
IPC: B65H23/188
Filed: 1968-04-16
Abstract: 1,204,942. Automatic registration control. HURLETRON Inc. April 16, 1968, No. 17947/68. Heading G3R. [Also in Division G4] The magnitude of the error in registration of a web 1, Fig.1, with a printing or cutting station, for example cutting station E, is determined by counting clock-pulses produced by an incremental encoder 21 coupled to the main drive shaft 23, these pulses being counted in both an initial counter which is zeroized every time a datum mark on the cutting cylinder 17 is photo-electrically detected 22E, and in an error counter which counts for a period determined by the photo-electric detector 20E of a mark put on the web at the first station A, and the attainment by the initial counter of a count, determined during the initial adjustment of the machine, which corresponds to the instant at which the mark on the paper should be detected for perfect registration to occur, the count attained by the error counter then being proportional to the magnitude of the error in registration and the relative timing of the detection of the mark on the web with respect to the attainment by the initial counter of the registration count, being indicative of the sign error. Error determination is performed for each station, except for the first, of all the multi-station machine shown and each error count can be employed, in a retroactive loop, to control compensators 11a, 11b, 11c, 11d to vary the phasing of the web at each station in order to reduce the errors in registration. The error for each station once every four cycles for example, or a running average, can be indicated. In the preferred embodiment Fig. 4 (not shown) the initial counter comprises two counters, an adjustable counter, i.e. a counter of fixed capacity (4999 as described) but able to produce an output at any switch-set count, and a reference generator, i.e. a counter of fixed capacity (99 as described) able to produce an overflow output, and they are so arranged that the count which represents perfect registration is bracketed by two pulses respectively one hundred clock pulses before and afterwards, these two pulses demarcating an inspection zone and unless the sensing of the mark on the web falls within the inspection zone no corrective action is taken and a visual indication is given. This detail prevents excessive corrective action being taken. During the initial adjustment of the machine the switches of the adjustable counter are set so that it produces an output 100 clock pulses before perfect registration, this being determined by coupling the adjustable counter to the indicator for the period of initial adjustment. There after the in indicator is coupled to the error counter. Block diagrams, employing conventional techniques, are described for the individual component of the system.

Title: Improvements in or relating to brake control systems for aircraft wheels and the like
IPC: B60T8/17
Filed: 1953-06-30
Abstract: 735,814. Airplane brake control system. SOC D'INVENTIONS AERONAUTIQUES ET MECANIQUES S. I. A. M. June 30, 1953 [July 15, 1952; Oct. 14, 1952], No. 18111/53. Class 103 (1). In a brake control system for aircraft of the type in which an inertia operated brakerelease device operates to prevent wheel skid, means sensitive to wheel rotation are provided, which operate to release the brake if the wheel is not rotating. The principle on which the system operates is shown in the circuit of Fig. 3, wherein electrical power may be supplied to a solenoid-operated brake cylinder release valve through two parallel lines, so that if current is passed through either line the valve is held open to release the brake pressure. A contactor I is in the line controlled by the inertia device and is shut only when the wheel approaches skidding conditions. Contactors R and S in the other line are held shut respectively only when there is a definite degree of wheel rotation as determined by the rotation sensitive device and when the wheel is off the ground as indicated by slackness in the wheel suspension. Under this arrangement since both contactors R and S will be shut off before the aircraft lands, it is impossible for the brakes to be applied until contactor R has been opened by speeding up of the wheels on touch down. When the aircraft is on the ground contactors I and S will be open so there will be no opening of the brake release valve and the brakes may be applied. In a fractical application as in Fig. 4, the wheel-sensitive contactor R is operated by a relay J energized by a circuit including a commutator K, Wheatstone bridge W and condenser L. The suspension contactor S is shown secured to the cylinder H of the shock absorber. The inertia device is of known type. In another embodiment the wheel rotation contactor R is operated by a centrifugal device.

Title: Improvements in nozzles for vacuum cleaners
IPC: A47L9/02
Filed: 1936-06-30
Abstract: 461,491. Vacuum - cleaner nozzles. ELECTROLUX, Ltd. June 30, 1936, No. 18130. Convention date, July 8, 1935. [Class 8 (i)] In a nozzle for vacuum cleaners including a nozzle body having a suction mouth of variable size and pivotally connected to a handle or suction tube, the effective suction mouth is progressively variable between two predetermined sizes by means of the handle by relative sliding movement between said handle and the nozzle body while the latter is maintained in its operative position, the angular position of the handle relative to the flow having no influence on the adjusted size of said mouth. In one form, Fig. 2, 3, a member 16 is mounted between end elements of the main nozzle body 17 so as to be movable vertically relative thereto, the member 16 being pressed upwardly with respect to the main body 17 by springs and its vertical movement being limited by pins ; the nozzle is provided with a central opening 23 and in this are mounted two pivoted plates 24 ; in the position shown in Fig. 2, the lower edges of the plates lie against the edges 26 of the normal suction mouth 27 so that the maximum suction opening is provided. On depressing the handle the member 16, which is pivotally connected to a part 15 communicating with the suction hose, is moved down so that inclines 28 formed on it, cause the lower edges of the plates 24 to approach each other, so diminishing the suction opening. When the member 16 is fully depressed it closes the non-adjustable openings 27 provided on each side of the central opening 23 so that suction is now confined to said central opening. On releasing the handle the member 16 is returned by the springs to its uppermost position, and the plates 24 are returned to their vertical positions by springs 29 secured to the member 16. In a modification, Fig. 7, adjustment of the suction opening is effected by rotation of the handle. A member 34 pivotally mounted on the shoe plate 31 and connected to the suction tube contains a cylindrical member 37, the members 34, 37 having registering openings 36, 38 ; a sleeve 44 receives the suction tube or handle and has a screw A engaging a groove on the part 34 so that it can rotate but cannot move axially ; the sleeve 44 is internally threaded to engage a member 39, a groove 46 on which is engaged by a lug 45 on the member 37. Rotation of the handle thus causes axial displacement of the member 39 which rotates the member 37 relative to the member 34 ; the size of the suction mouth defined by the openings 36, 38 is thus varied. An indicator may be provided to show the size of the nozzle opening. The plate 31 may be dispensed with. In all forms, the suction openings may be large in the centre and decrease in width towards the ends as shown in Fig. 8.

Abstract: 621,509. Mechanical toys. NORELIUS, J. O. G. A. June 18, 1946, No. 18298. [Class 132 (iii)] [Also in Groups XXXI and XXXIII] A vehicle moving on a floor is remotely steered through a resilient member connected to the steering apparatus of the vehicle and contacting a ceiling above the floor such' that lowering of the member relative to the vehicle causes the latter to run in a curve in one direction and raising of the member causes the vehicle to run in a curve in the opposite direction, so that the curve of the course of the vehicle will be decided by the distance between the floor and the ceiling. As shown the vehicle 12, Fig. 2, is a toy and has a lever 17 pivoted at 16 connected to the front steering wheels or wheel 15  by suitable linkage, so that depression of the top end 19 of the lever 17 will cause the vehicle to steer to the left, and raising it will cause steering to the right. The vehicle 12 is placed between the floor 1 and the ceiling 2, which consists of a brass wire mesh, connected by links 4, 5 to the floor, so that the lever end 19 engages the ceiling. The distance between the floor and the ceiling is uniformly varied by means of a wire 7 attached to the link 5 and a wire 11 likewise joined to a similar link on the reverse side and both are wound over a column 8 controlled by a handwheel 6. The distance between the floor and ceiling may vary from one part to another and not be varied mechanically, thus there may be a ridge on the edge of the ceiling to steer the vehicle back towards the centre of the floor. The rear wheels 13 of the vehicle may be driven by an electric motor contained in a box 14 connected to the floor through one of the wheels or a drag contact 21 and to the ceiling by the lever 17. The motor may be D.C. and a reversing switch may be inserted in the circuit between the supply and the floor and ceiling so that the vehicle, may be driven forwardly or rearwardly. A variable resistance may also be inserted in the circuit to vary the speed of the vehicle, this being operated by a foot pedal. The floor may take the form of a basin filled with water, and the vehicle can be a water vessel driven by a propeller through an electric-motor, the contact with the ceiling being by a lever similar to the lever 17 and to the bottom of the basin by a drag contact.
