Title: Improvements in or relating to shoe upper drafting apparatus
Inventor: BODDY HAROLD
IPC: A43D13/00
Filed: 1968-06-04
Abstract: 1277019 Boots &c RALPHS UNIFIED Ltd 2 June 1969 [4 June 1968] 26540/68 Heading A3B Apparatus for applying a drafting pull to a shoe upper on a last includes means for gripping the forepart of the shoe upper at each side of the last, the grippers being movable lengthwise of the shoe and the last being movable heightwise of the shoe to apply the pull to the upper. The grippers are mounted on arms 45 and consist of jaws 75, 77 (Fig. 3) which are opened and closed by air motors 74. The jaws can be moved about a vertical axis and the gripper assembly can be moved about a horizontal axis by screw 69 so that the jaws 75, 77 can be positioned parallel to the lasting margin of the upper. The arms 45 can swing about vertical pivots and are moved widthwise of the shoe by a toggle mechanism (not shown) operated by a lever 56 which is driven by air motor 54. The position of pivot 57 can be adjusted by screw 59 to adjust the initial position of the grippers widthwise of the shoe. The gripper assembly and arms 45 can also rotate about pivot 44 against the action of a pneumatic spring 63 acting on lever 62 and which urges a stop screw 60 into contact with upright 41a. Thus the grippers are held in a predetermined height-wise position determined by screw 60 until the downward force exerted by the lasting margin exceeds a predetermined value when spring 63 is compressed and the grippers move downwardly with the last 15. The upright 41a forms part of a carriage 41 which can be moved along a guide rod 25 by air motors 29 to move the grippers lengthwise of the last 15. The last 15 is carried by a pin 13 on a block 12 which can pivot about a pin 14 on the last part 10 and is urged into an uppermost position 'by a compression spring (not shown). The last is tilted downwardly after the upper has been gripped by rollers 89 on an arm 87 carried by a lever 84 which is turned about pivot 44 by air motor 85. The machine has an automatic control circuit and operates as follows: the motors 74 are operated to close the grippers and the motor 85 is operated to depress the last 15 and thus pull the upper across the last. The motors 29 then operate to apply a lengthwise pull to the upper and then motor 54 is operated to move the grippers towards each other. The drafting machine may be incorporated in a heel seat moulding and lasting machine of the type described in Specification 958212.

Title: Impedance matching terminations for dielectric guides
IPC: H01P1/24
Filed: 1936-10-02
Abstract: 472,725. Signalling through dielectric guides. STANDARD TELEPHONES & CABLES, Ltd. (Western Electric Co., Inc.) Oct. 2, 1936, No. 26785. [Class 40 (v)] Relates to dielectric transmission lines for carrying high-frequency energy in the form of waves, which may be variously polarized. The invention consists in the use of absorbing or reflecting elements so arranged in relation to the guide as to produce a desired terminal impedance, or transformation effect. As shown in Fig. 9, a wave travelling along the guide 101 from the left is partly reflected, partly absorbed, and partly transmitted by radial resistance wires 107 which are connected by an axial conductor 103 to an adjustable plunger 102. The transmitted energy is totally reflected from the face of an adjustable metal plunger 102, and the wave may subsequently be completely absorbed by successive interaction between the wires 107 and the plunger 102. The wires 107 may be replaced by a single resistance wire, or by a highly-conducting wire with a " lumped " resistance, in association with crystal rectifiers or thermo-electric couples, to detect the signal currents as shown in Fig. 13. Fig. 15 shows a method of introducing an impedance transformation. The main " guide " 108 opens through an iris diaphragm 109 into a cross-chamber 110 which is closed at both ends by adjustable pistons 102 and 102<1>. The element 106 may be an absorbing disc or a resistive conductor. For a given position of the inlet 108, and a given distance between the pistons 102 and 102<1>, a standing-wave system is set up, as shown by the curve ABC, inside the cross-chamber, and its amplitude can be controlled., to secure a step-up or step-down effect, by altering the relative dispositions of the movable parts. Certain settings are found to be critical, and can therefore be used to give high selectivity. In Fig. 20, antenna members 127 pick up waves from the upper guide and transfer them through the impedance-matching Lecher-wire coupling 121 to similar members 127<1> in the lower guide, which has a different diameter from the first. The absorbing elements may be mounted externally to, or in, or associated with the walls of the dielectric guide. They may also be arranged to ensure the maximum transfer of energy to the guide from an oscillating source. In Fig. 33, resistance films 51, 52, 53, spaced apart by dielectric material 56, are used to absorb waves of different selected polarities and different frequencies. Various modified arrangements suitable for this purpose are also described. Fig. 55 shows how lateral branches 83, 831 and 84, 84<1>, of suitable diameters, can be arranged to separate out waves of different polarity, and of different frequency from those flowing along the main guide 54.

Filed: 1923-10-29
Abstract: 224,370. Rehnqvist, N. P. Oct. 29. 1923. Stamp-applying.-A stamp is withdrawn from a roll in a receptacle carried bv a punch applied to a letter, and severed from the strip by a motion of the receptacle produced by a plunger in the punch. The receptacle 4 is pivoted to a plate 8 moving in a transverse slot in the punch 1. When the plunger 23 descends it bears on a sectorshaped plate 22 moving in a vertical slot in the punch and bearing on the receptacle 4 so as to move it into the position shown in Fig. 2, thus withdrawing another stamp for attachment. The motion of the receptacle is then checked by a screw 14, so that further motion of the plunger causes the receptacle to twist sideways, tearing off the stamp which is held by the punch 1. To prevent the strip of stamps from being further drawn out while the stamp is being drawn out, a feed-roll 6 is then braked by a lever 27, the other end 25 of which is gripped between the receptacle 4 and screw 14.

Abstract: 1,207,141. Printing machines. HOE-CRABTREE Ltd. 6 Sept., 1968 [12 June, 1967], No. 27099/67. Heading B6C.  An offset printing-press comprises (a) two printing couples 1, 2 and 3, 4, the blanket cylinders 2, 3 of which in a first condition of the press co-operate with each other to print on both sides of a web passed between them, and (b) an impression cylinder 7 arranged above the cylinders 2, 3, the blanket cylinder 3 and the impression cylinder 7 being movable between the first condition and a second condition in which both blanket cylinders 2, 3 co-operate with the impression cylinder 7 whereby a web can be passed between the blanket cylinders and the impression cylinder to receive two impressions e.g. two colour images on one side of the web. The axes of the plate cylinders 1, 4  are fixed. The blanket cylinder 2 is mounted in eccentric bearings rotatable to trip the cylinder and having arms 31 connected by links 30 to arms 16, 24, Fig. 2, keyed to a shaft 13 supported on frame members 8, 9. An arm 26, Fig. 1, fixed to the arm 24 is connected to an air ram 10 operation of which rotates the shaft 13 to trip the cylinder 2. A third arm 25 fixed to the arms 24, 26 is secured by a bolt 29, Fig. 2, to a lever 20 keyed to a hollow shaft 12 surrounding the shaft 13. Levers 18, 19 are keyed to the shaft 12 and are connected by links 36, 37 to eccentric bearings of the cylinder 3, so that operation of the ram 10 also causes the tripping of cylinder 3. The bolt 29 connecting the levers 20, 25 can be engaged in either one of two bolt holes in the lever 20 spaced apart by 180 degrees. With the bolt 29 in one position, the cylinders 2, 3 are in the first condition for printing on both sides of the web. If now the bolt 29 is removed, the shaft 12 turned through 180 degrees, and the bolt inserted in the other hole, the eccentric of cylinder 3 is adjusted so that the cylinder is separated from cylinder 2 and is in a position to engage the impression cylinder 7 when the latter has been adjusted as described below. The impression cylinder 7 forms part of a printing couple including a fixed axis plate cylinder 5 and blanket cylinder 6. Tripping mechanism operated by an air ram 11 and identical with that described for the cylinders 2, 3 is provided for the cylinders 6, 7. If, however, the cylinder 7 is required to engage the cylinders 2, 3 to obtain a two colour impression, the coupling 29 of the tripping mechanism of cylinders 6, 7 is displaced 180 degrees as described above, thus moving the cylinder 7 to the required position 7a whilst remaining in contact with the cylinder 6. After receiving the two colour impression in the second condition, the web may pass between the cylinders 6, 7 to receive a third colour impression and after being printed on both sides in the first condition it may be passed between the cylinders 6, 7 to receive a so-called spot colour on one side.
