Title: Stripping device for weft bobbins or pirns for looms
IPC: B65H73/00
Filed: 1958-08-20
Abstract: 865,063. Stripping bobbins &c. ROHL, G. Aug. 20, 1958 [March 19, 1958], No. 26811/58. Class 120(3). A stripping device for pirns having stripping jaws movable along the axis of the pirn is characterized in that the jaws are carried by endless chains or other endless means. As shown, the device, which may be attached to a loom and driven from the mainshaft thereof, consists of an inclined slide 27 of rectangular cross-section having a guiding slot 30 (not shown) corresponding to the shape of the substantially empty pirn (see Fig. 1, not shown). Below the slide, is a reception slot 33 which has an enlargement corresponding to the pirn head 29. Yieldable cheeks 39 grip the head 29 whilst the stripping members 18 carried on endless chains 6 clean the waste weft from the pirn. The chains 6 pass over sprocket wheels 4 and 5 and over guide members 7 provided with holes 9, 10, to enable members 7 to be adjustable transversely to the axis of the pirn. Behind the cheeks 39 is a reception slot of smaller width than the head 29 into which the bobbins from slide 27 fall. A bellcrank lever 34, 36, actuated by a stud 37 attached to the endless chain 6 displaces the pirn from the reception slot into the cheeks. The bellcrank lever is held inoperative by a spring 38.

Abstract: 787,290. Magnets. SIEMENS & HALSKE AKT.-GES. Sept. 21, 1955 [Sept. 21, 1954],No. 26983/55. Class 35. [Also in Group XL (a)] Travelling wave or other high-frequency electron tube apparatus comprises magnetic focusing means consisting of one or more permanent magnets, e.g. a single tubular magnet or a plurality of bar magnets 4, 5, Fig. 3, or 19 . . .  26, Fig. 4B, wherein a flux guide is widened at at least the end of the tube surrounding the gun and the cross-section of the narrow part of the guide tube, Fig. 3, and/or that of a shunting guide tube 18, Fig. 4B, is progressively reduced from the junction between the wider and narrower parts of the guide tube either continuously or in small steps. The resulting increase in field along the narrow part of the guide tube away from the stepped portion counteracts the normal decrease in field in this direction due to the diverging lines of force and ensures that the resultant field is uniform or increases towards this end of the guide tube. In one form, Fig. 3, the cross-section of the guide tube 1 tapers from the stepped portion towards the collector end 16, the angle of taper being up to 10 degrees. The gun has welmelt 13 and focusing electrodes 14, 15, and the delay line is a helix 12. In another embodiment, Fig. 4B, the guide tube 17 is of constant wall thickness but a second guide tube 18 has a wall of tapering thickness and can be slotted as shown.

Abstract: 811,472. Pneumatic servo-brakes. BENDIX AVIATION CORPORATION. Sept. 4, 1956 [Sept. 19, 1955], No. 27046/56. Class 103 (1). [Also in Group XXIX] With the plunger D, Fig. 1, of the master cylinder in the retracted position shown, atmospheric air flows through a pipe 52 into a front chamber 50 in a power cylinder B past a valve seat 60, Fig. 2, through an annular space between a member 58 abutting a diaphragm, on which member is the seat 60, and an annular closure member 26 having its forward end secured in a flexible flange 30 attached to a boss 18, through the diaphragm chamber 16 in a piston C, Fig. 1, and enters a rear chamber 54 via a passage 56 in the piston C. The latter, which separates chambers 50, 54, comprises parts 10, 12 bolted together and between which is the diaphragm; the part 10 incorporates the boss 18, Fig. 2, that houses the valves and plates 49, 76 which serve to guide the latter. Upon depressing a brake pedal 72, Fig. 1, a rod F moves the member 58 to bring the seat 60 against the flexible flange 30 thereby preventing the ingress of atmospheric air to the chamber 54; continued movement of the pedal forces the flange 32 of the closure member 26 away from its seat 22 to enable the chamber 54 to be connected to a vacuum source by way of a chamber 34, the diaphragm chamber 16, Fig. 1, and the passage 56 whereupon the plunger D together with the piston C, moves inwardly due to the pressure differential thereacross until the seat 22, Fig. 2, which is integral with the boss, 18, engages the flange 32. In this position the seat 60 still abuts the flange 30 and both valves are lapped. If more or less braking force is required the pedal is further depressed or retracted whereupon a new lapped position of the valves is obtained. The closure member 26 may comprise a single piece of rubber, or a one-piece rigid member whose forward flange 30 slides within the boss 18.

Abstract: 1349597 Photographic processing apparatus ADDRESSOGRAPH-MULTIGRAPH CORP 19 April 1971 [27 April 1970] 27107/71 Heading G2A Exposed diazotype sheets are developed by apparatus comprising a rotatably mounted applicator roller 52 having a surface adapted to carry a predetermined quantity of developer liquid issuing from a supply pipe 100, a wiper blade 86 for removing excess developer liquid from the roller surface, and a pressure blade 88 which forms a developing zone 118 along an area of contact between the pressure blade and the roller surface, the blades being movable into and out of engagement with the roller by an interconnecting linkage member during and after operation of the apparatus. The blades are formed of flat, resilient sheet metal and the roller has a central shaft 54 of metal and an outer layer 56 of a smooth non-porous resilient material such as rubber. The blades are operated by the mechanism shown in Fig.2. Arms 144, 146 are connected to the ends 148, 150 of tubular shafts 90, 92 which carry the blades 86, 88, and each arm carries a cam follower roller 160, 162 disposed within cams 164, 166 formed in a cam plate 128. During operation of the apparatus, an electric motor rotates cam plate 128 initially through 40  degrees to move only blade 86 into contact with the roller. At the same time roller 52 rotates and developer liquid is pumped to tube 100. After a delay of three seconds to permit the roller surface 58 to be evenly coated with liquid, cam plate 128 is moved through a further 80 degrees so that blade 88 is brought into contact with roller 52. A sheet fed into the apparatus along guide 122 will now be fed past the developing zone to exit via aperture 124 in a substantially dry to touch state. The cam plate carries cam surfaces T 1 , T 2 , T 3  on its periphery to engage followers 140, 142 which operate contacts 136a, 136b, 138a, 138b. These contacts together with a manually actuated switch (182) Fig.4 (not shown) controls the apparatus so that upon operation of the manual switch to a copy demand position the apparatus is automatically operated in the correct sequence, and upon operation of the manual switch to its initial position the apparatus is restored to a standby condition with the blades out of contact with the roller. The blades are disposed on opposite sides of the roller so as to equalise the pressure forces thereon.
