Abstract: 700,930. Conveyers. JOHNSON & JOHNSON. May 25, 1951 [June 1, 1950], No. 12345/51. Class 78 (1). A package discharge and stacking device comprises an endless conveyer provided with spaced means for supporting and conveying the packages vertically downwards, an ejector operated in timed sequence with the conveyer and arranged at a point in the downward run and stationary stop means with which the ejector co-operates, the arrangement being such that the packages are stopped by the stop means without interrupting operation of the conveyer, and are then ejected by the ejector. As shown, adhesive bandage units 11 are pushed along a guideway (not shown), by pushers 15 on a pair of endless chains 13 which are passed over a driving sprocket 14 and thereafter pass downwardly past the entrance to a magazine 12, the pushers 15 now acting as platforms for the bandage units which now rest against the chains. Guides 16 prevent the bandages from falling forwards. A pair of cam wheels 35 are located in register on a shaft 36 driven by a sprocket chain 37 from the sprocket 14 and the lobes 38 of the cams are so shaped that a, flat portion 40 arrives behind each bandage as it comes opposite the magazine entrance, where a stop 24 forming an extension of the magazine floor 22 prevents further downward movement of the bandage. The bandage is then pushed by the portion 42 of each cam lobe past a pawl 30 on the end of a spring 26 secured to a top plate 28 of the magazine. Finally a concentric portion 41 of each cam lobe straightens the delivered bandage into vertical position in the magazine.

Filed: 1936-04-30
Abstract: Apparatus for the intermittent application of a treating agent to yarns and other textile materials consists of a source of supply of yarn, take-up means for said yarn, a source of supply of treating agent and means for applying <PICT:0460111/IV/1> <PICT:0460111/IV/2> said agent to the yarn comprising at least two devices adapted to cause said yarn to contact with the treating agent supplied, means for driving each of said devices, and means for causing the ratios of the speeds at which said devices are driven to vary continually. Fabric made up from yarn treated by this apparatus exhibits a uniform, scattered or broken up effect presenting no definite pattern.  In the apparatus described, the thread 91 is drawn from a supply package on the table 88, passes through a tensioning device 44, over the rod 43 and paddle wheel 47, across a slot in the container 52, through a vertically reciprocating guide 87, and a horizontally reciprocating guide 69, on to the take-up 65.  The thread is intermittently raised out of contact with the roller 55 by means of the blades of the paddle wheel 47, and also by means of the guide 87.  The paddle wheel is driven at a variable speed from the power shaft 4, by means of the cone pulleys 16 and 17, and the belt 18 which is moved across the cone pulleys by the cam 25.  The guide 87 is reciprocated by means of the cam 77 which may be of any suitable shape, and which also is driven from the power shaft 4.  The treating agent may be a dyestuff, a discharge which may or may not itself contain a dyestuff and/or a swelling agent for the materials treated, a resist, a loading or weighting agent such as is described in Specifications 258,874, 260,290, [both in Class 42 (i)], 277,102, [Class 38 (ii)], 280,094, 281,084, and 285,941, [all in Class 42 (i)], a lustring or delustring agent, a size or finish, or a saponifying agent, a number of which are specified.  The degree of saponification may in the first instance amount to sufficient to cause a loss in weight of 2--7 per cent only, and the thread after forming into cloth may be treated in a saponifying bath which saponifies further the places of the yarn already partially saponified.  The second saponifying bath may have a pH value of 8--10,5 and the conditions of treatment are such that the unsaponified portions are unaffected; a bath containing 5--10 grams of soap per litre in an aqueous medium at 70 DEG  C. to the boiling point is suitable.

Road-traffic signals on vehicles; semaphore signals; audible signals.-Relates to signalling apparatus for road vehicles and aeroplanes, of the kind in which front and rear indicators are mechanically operated by a control device near the driver's seat as described in Specification 6456/15, and comprises means for automatically completing a circuit through an electric hooter when the control wheel or handle is operated to alter the indicators, the hooter also being independently operable. Specifications 145,816 and 157,697 also are referred to. The control wheel 31 is slidably mounted on the squared end 33 of a partly hollow shaft 32 rotatably mounted at 36, 37 in a casing 27, 28 carried by a bracket 28<b>. The wheel 31 is normally pressed outwards by a spring 43 so that it is locked by engagement of an arm 30 thereon with one of a number of notches 28<a> in the projecting periphery of the casing lid 28, the notches corresponding to the four indicating positions. Secured to the wheel 31 and passing through the hollow part of the shaft 32 is a central stud shaft 41 carrying a con. tact member 47 which, when the wheel 31 is pushed inwards, completes an electric circuit through the hooter by engaging a contact strip 45 carried by an insulated base 44 in the casing. The contact strip 45 being circular the hooter is scunded continuously whilst the wheel is rotated to alter the indicator, ceasing when the wheel is allowed to spring back into a locked position. The hooter may be independently operated by pushing the control wheel inwards without rotating it. The axial movement of the control wheel is limited by a cross pin 42 connecting the rod 41 to the wheel hub 35 and passing through a slot 32a in the squared shaft end 33. A pinion 38 on the shaft 32 transmits movement to the indicators through a short length of chain and Bewden wires. The Provisional Specification described a modified construction in which the control wheel and attached parts are not axially slidable, the contact member thereon, in this case, co-operating with a series of segmental fixed contact strips arranged on the insulating base so as to leave gaps at the indicating positions. A separate press-button co-operating with one of the strips, is provided for independent actuation of the hooter; two grooved pulleys for attachment of Bowden wires are provided on the operating shaft, and a spring push catch on the control wheel engages the locking recesses in the casing rim.
