Abstract: 627,076. Fluid-pressure gauging apparatus. RUPLEY, F. L. Jan. 28, 1947, No. 2646. [Class 106 (ii)] A fluid-pressure gauging device comprises a measuring instrument communicating with a gauge head having a port with an effective outlet area variable in accordance with the size of the work-piece being measured and a handle provided with a longitudinal main bore and a plurality of auxiliary bores which communicate with the main bore and into which the gauge head and measuring instrument can be selectively inserted. As shown, the main bore 12 contains cup-shaped members 14, having restricted openings 16 to which compressed air is supplied via a conduit 18, and three bores 20, 22, 24 communicate with it. The gauge head 28 is mounted on a coupling 26 in the bore 20, the measuring instrument 44 is secured in the bore 24 while the bore 22 is closed by a plug 46. The gauge head 28 has an axial bore 30 communicating with the main bore 12 and has a cylindrical outer end having a peripheral groove 34, and slots 40 to permit exhaust of air when the head is inserted into a work-piece. The measuring instrument 44 has a centre post 48 attached to a Bourdon tube 50 which has an aperture 66 and the free end of the Bourdon tube drives, via a linkage 52 and sector 54, a shaft 58 on which is a pointer 60. A glass cover 70, held by a bezel ring 72, has a mark 90 on it and a bushing 78 extends through a hole in the cover. In the bushing is a cup-member 80 having a pointer 82 and a knob 84 connected by a dowel pin 88. A screw 86 also connects them and is tightened to frictionally retain them in any position of adjustment. The mark 90 and pointer 82 are set to show the upper and lower tolerance limits by placing master gauges of these sizes on the gauge head and adjusting the mark 90 and pointer 82 respectively to the positions shown by the pointer 60.

Title: Improvements in electric starting devices for internal combustion engines
IPC: H04L13/04
Filed: 1920-01-29
Abstract: 155,136. Imray, O., (Bosch Akt.-Ges., R.). Jan. 29, 1920. Systems for continuous-current motors only.- In an electric starting-motor, the armature is rotated slowly while being coupled to the engine and then rotates faster and with higher torque, a high-resistance field winding g being cut out by a switch m displaced by the axial movement of the armature. The movement of the switch m is completed smartly under the attraction of an electro-magnet i, which then holds the switch closed as long as the main switch e is closed. In the form shown in Fig. 1, the winding g is initially in series with a low-resistance winding f and is completely cut out by the switch m. The axial movement of the armature shaft b brings a pinion a into mesh with the engine fly-wheel c. In a modification, Fig. 3, the low-resistance winding f is initially out of circuit and is afterwards connected in parallel with the high-resistance winding g. The electro-magnet i controlling the switch is in series with the winding g. The switch may be a pivoted arm actuated directly by the axially-moving starter pinion, or a switch r, Figs. 3 and 4, actuated by a sliding bar ten. gaged by a flange v on the armature shaft b. The switch member r, Fig. 4, is mounted on an electro-magnet armature held by a spring 5 within the cover 11 of the casing 10, so that the armature is shielded from the attraction of the electro-magnet i. When the member r is moved to the right in Fig. 4 by the bar t, the armature l is strongly attracted and the closing movement of the switch r is completed quickly.

Title: Improvements in or relating to machines for feeding, moistening and cutting lengths of gummed tape
IPC: B65H35/00
Filed: 1919-02-06
Abstract: 142,557. Jackson, W. J. Mellersh-, (National Binding Machine Co.). Feb. 6, 1919. Feeding webs.-Relates to a shop appliance de. signed to feed, cut, and moisten a definite length of gummed tape for binding parcels &c., one free end of the severed length being left projecting from the machine whilst the other end is still held therein. The roll 3 of gummed tape rests in a receptacle at the rear of the frame 1, and the end of the strip passes through feed rollers 6, 6<A> and between the cutting-blades 21, 22, forward to a moistening-roller 27, from which it projects ready to be applied to the parcel &c. The lower feeding-roller 6 is driven by depressing a spring-controlled finger-piece 17 to an extent that is limited by an adjustable stop 19 placed in a guide frame 18. This movement rotates the feed roller by the engagement of a segmental rack 14 with a pinion loose on the shaft of the roller. Mounted on the pinion is a flanged disk 12, Fig. 8, carrying a pawl 11, which drives a ratchetwheel 10; this wheel is also loose on the roller shaft but engages a cross-pin 8 set thereon by means of two segmental driving-lugs 9. This arrangement provides a lost-motion connexion between the actuating finger-piece 17 and the feed-roller whereby the initial downward motion of the finger-piece allows the spring controlledscissors 21, 22 to open before the tape is fed forward between the blades by the feed-rollers. The strip is severed by the blade 22 on the return movement of the finger-piece under the influence of the spring 16. The moistening-roller 27, which is preferably of the kind described in Specification 142,423, [Class 18, Boxes &c.], is driven by a pinion from the feed-roller at a greater peripheral speed than the latter so as to have a wiping action against the gummed surface of the tape.

Abstract: 1300374 Draughting machines MISOMEX AB 22 Jan 1970 [4 Feb 1969] 3161/70 Addition to 1261443 Heading G1X In apparatus for reproducing a rectangular pattern draft on a reproduction blank as in the parent Specification an arrangement is provided for reducing or enlarging the scale to which the pattern is reproduced in one direction only. Such an arrangement allows for the distortion produced when the blank is subsequently stretched on a roller in a rotary printing operation. To this and the apparatus comprises a screw-threaded shaft 25 which is driven by a motor 28 for traverse of a writing head carriage 24 as in the parent case, the movement of the carriage 24 being in response to movement of a nut 51-52 along the shaft 25. A wedge 60 is interposed between the nut and a projection 56 on the carriage 24 and the thicker end of this wedge carries a wheel 65 which engages a guide bar adjustable in relation to the shaft 25 by virtue of the fact that it is pivotally mounted at one end and mounted for movement towards and  away from the shaft 25 by means of a screw 64 at the other, so that as the nut 51, 52 moves along the shaft 25, the movement of the carriage 24 is either decreased or increased relative thereto due to the movement of the wedge 60 into or out of the space between the nut and projection 56 which are held together by a spring 61. In the positions shown in the drawing movement of the nut through a distance A-C will produce a corresponding movement of the carriage 24 through a lesser distance A-B.

The ball segment of Fig. 3 (not shown), has slots extending inwards from the outside, the bases of the slots not being parallel with the segment bore and the stud and the distance from the slot base to the bore being greater near the ball part 3. The ball segment of Fig. 4 (not shown), has slots extending outwards from the bore so as to form recesses which axially extend not as far as the ball part 3 and the lower end of the segment. The ball segment may have slots according to Fig. 3 and to Fig. 4; arranged alternately. The ball segment of Fig. 5 (not shown) is radially divided by slots into e.g. three sectors, small projections forming the bridging pieces being provided adjacent the bore on one of each pair of facing sector surfaces to abut the facing sector surface.
