Title: A method of and a device for treating a textile web to achieve a press-board press effect
IPC: D06C15/00
Filed: 1968-08-26
Abstract: 1,215,613. Press treating textile webs. H. KRANTZ VERWALTUNGS G.m.b.H. 26 Aug., 1968 [13 Sept., 1967], No. 40654/68. Headings D1L and D1S. In a method of treating wool webs to achieve a press-board effect the web is given a moisture content of 10-17% by weight and passed between two pairs of pressing surfaces, one or both of which revolves, at a pressure of 10 to 40 Kg./cm<2> and at a temperature of 40 to 90 ‹C. A wool web 13 moving axially parallel to a pair of rotating drums 6, 8 is deflected by a member 11 past nozzles 16 to achieve its desired moisture content, beneath a spring loaded roller 15 and into the spandrel between belt 9 and drum 6. The web is then subjected to a first pressure stage whilst being moved through 180‹ of the drum's 6 rotation. The web is then parted from belt 9 by a roller 17 whilst the belt is cleaned by a brush 18. The web is then subjected to a second pressure stage between belt 9 and drum 8. It is then removed from the belt 9, passed between coolers 21 and deflected by a member 12 along a path parallel to its original feed path. The heat is provided by infra-red heaters 19.

Abstract: 1,104,251. Duplicating record tapes. J. M. AHY. 16 Oct., 1964 [16 Oct., 1963], No. 40848/63. Heading G5R. Signals recorded on an endless loop master band B are duplicated on a copy band B1 by passing the band B past a playback assembly 102 containing as many heads as there are tracks or part tracks and coupled through amplifier 106 to a similar recording assembly 105 acting on the copy band. If the signals were originally recorded on a single helical track on the master band, the latter is preferably cut and a blank section spliced in before duplicating; the blank section is initially set opposite the playback assembly 102 and the assemblies 102 and 105 are driven across the respective bands by cams 108 and 109 which rotate once whilst the band B makes one complete revolution. A marking device 110, e.g. a writing device, indicates the ends of the copies and a cutting device 107 cuts the copy band into record lengths.

Filed: 1971-09-08
Abstract: 1358198 Suction filling machines A T O Inc 8 Sept 1971 [8 Sept 1970] 41946/71 Heading B8T A filling head for a vacuum bottle filling machine consists of a sealing assembly, Fig. 12 (not shown), to provide air-tight contact between the filling head and bottle, a bottle centring assembly, Fig. 17 (not shown), and an elongate filling nozzle assembly, Fig. 5 (not shown). The filling nozzle may be provided with a sleeve valve, Fig. 26 (not shown), the sealing and centring assemblies and the sleeve valve being movable relative to the nozzle, and the sealing assembly having a leak-tight contact with the filling nozzle so that the mozzle height may be varied without breaking the vacuum seal. Where a sleeve valve is provided, a cam M2 Fig. 36, permits cam follower roller 58 of the nozzle assembly, Fig. 5 (not shown), to move along surface 208 from station I to II, the nozzle assembly bringing down the sealing assembly with it until member 92, Fig. 23, is in contact with the bottle top, the filling tube 20a being passed through the member 92 until the collar 62 of the nozzle assembly contacts bracket plate 64. The sleeve valve assembly moves down with the nozzle until the lower member 134 contacts the lower member 76 of the sealing assembly. Further downward movement of the filling tube 20a opens ports 22a and 24a. During filling, the sealing element 92 is maintained in contact with the bottle by roller 98 and cam M3. After a predetermined liquid level is obtained, cam 146 of the sleeve valve assembly contacts cam M4 lifting lower member 134 and the nozzle assembly to a new height, the ports 22a and 24a remaining open. On completion of the filling the ports are closed by raising the nozzle assembly by moving rollers 58 along surface 214 of cam M2, but holding the sleeve valve assembly by cam M5. On closure of the ports, roller 146 is freed and the nozzle, seal and valve are raised to their inoperative position. The cam control may be replaced by a friction control, the sealing assembly being connected to the stem 42 of the nozzle assembly by a screw and jaw arrangement, Fig. 15 (not shown), and the sleeve valve modified, Fig. 29 (not shown). The sealing member 92, Fig. 25 (not shown), is held in contact with the bottle top by the downward movement of the nozzle under the influence of a weight (116). On raising the nozzle to a predetermined height, the seal is held in contact with the bottle by the valve sleeve member (152) which is held down by cam (M7), Fig. 37 (not shown). The centring and sleeve valve are optional and the heads are located on a turret (170), Fig. 34 (not shown), arranged close to a bottle conveyer, the heads being mounted on hangers (16), Fig. 10 (not shown), within a frame (178), Fig. 33 (not shown). A nozzle having an eccentric air tube (28a), Fig. 31 (not shown), may be provided, the tip of which has a groove (226) for an 0-ring (228) which forms a leak-tight seal with the lower edge of the sleeve valve (130).

Abstract: 1284102 Loading and unloading bales SPERRY RAND CORP 25 Aug 1969 [26 Aug 1968 29 May 1969] 42214/69 Heading B8E A bale wagon comprises an unloading table 200 from which bales are unloaded one at a time by a cross conveyer 350, the table also including bale engaging means 352 which separates the upper bales of a tier of bales from the lowermost bales. The conveyer 350 comprises an endless chain 354 of which the upper run is disposed below the surface of the table 200 and a pair of bale-engaging paddles 358 are fixed to the chain. The bale engaging means 352 comprises hook members 362 carried on a shaft 364 rotatable by an arm 374. This arm includes a conveyer-engaging assembly 394 and is normally maintained in the full-line position, Fig. 3 by a spring 384. In operation, assuming the paddles 358 are in the position shown in Fig. 4 and the hooks 362 are retracted, movement of the conveyer chain 354 as shown in Fig. 4 will cause the arm 374 to move to the broken-line position (Fig. 3) and to be held by a latch 382. This movement of arm 374 causes the hooks 362 to engage any bales overlying them and to move the bales to the position in Fig. 2, the lower layer of bales thus being free for discharge by the conveyer 350. Continued movement of the conveyer chain causes the assembly 394 to be disengaged therefrom and one of the paddles 358 to discharge bales laterally of the wagon. The other paddle then causes release of the arm 374 by engaging a trip arm 386 and the next lowest layer of bales is allowed to fall to the lowest position, ready for discharge. After the last layer of bales has been discharged another tier of bales is deposited on the table 200 by a rack 300.

Abstract: 1,152,216. Inductor alternators. NATIONAL RESEARCH DEVELOPMENT CORP. 22 Sept., 1967 [28 Sept., 1966], No. 43435/66. Heading H2A. In an inductor alternator, flux-reversal instead of only flux-ripple, is achieved by placing a squirrel-cage winding in alternate rotor slots. The stator is D.C. excited by distributed conductors in the bottoms of the slots to produce two poles on either side of the neutral axis B-B<SP>1</SP>. This induces a similar pattern of currents in the rotor bars, and since these are in alternate slots, the intervening teeth are given alternate polarities, which induces flux-reversal in the stator teeth. The output A.C. winding is at the top of the slots. The region of the neutral axis B-B<SP>1</SP> is not thus polarized but acts as a " commutation " zone for the rotor currents and interpoles may be provided for this purpose. The machine may be made polyphase by increasing the number of slots to accommodate additional windings, the rotor bars being grouped in threes spaced by three empty slots (Fig. 3, not shown). The excitation of the machine may be increased by replacing the rotor bars by one or more turns a-d round individual teeth, as shown in Fig. 8. The machine may be of any polenumber, and stator and rotor may have different slot-numbers. " Commutation " of the rotor currents may be facilitated by grading the stator excitation winding in a sinusoidal manner (Fig. 13, not shown).
