Title: Improvements in or relating to winding and paying-out apparatus
IPC: B66C7/00
Filed: 1939-06-15
Abstract: 530,699. Transporter cranes ; electric motor control systems. STRINGER & SON (CRADLEY HEATH), Ltd., and POWELL, J. W. June 15, 1939. No. 17465. [Classes 78 (iv) and 78 (v)] [Also in Group XXXVII] Winding and paying-out apparatus, more particularly for transporter cranes, comprises a two-speed gear consisting of a toothed wheel 49 in the driving sequence between an electric motor 14 and a winding drum 17. The wheel 49 is in constant mesh with two spur wheels 33 and 34 mounted loosely upon shafts 23 and 26 respectively. Each wheel 33, 34 can be coupled to its shaft by clutches 40 which are thrown into and out of engagement by a rocking arm 44 medially pivoted at 45 so that when the arm 44 is thrown over in either direction one of the clutches is in and the other out. The shafts 23, 26 are geared together by multiplying pinions 27, 28, 30, 31, giving, say, a twelve to one speed ratio. The wheel 49 may be loose on its shaft 46 and coupled thereto by a dog clutch 50, 51 the teeth 52 of which tend to force the wheel 49 sideways against a brake 53 when the motor 14 is stopped and the load tends to reverse the motion, thus constituting a self-sustaining gear. The brake 53 consists of friction discs between which is a ratchet-wheel 57 held by a pawl 58, which has a tail co-operating with an adjustable stop and a link connecting it with a brake band 63 which prevents chattering. The rock-shaft 45 may be biassed by a weighted arm 65 to keep the slow-speed pinion 34 normally in driving engagement, and this arm may be raised to throw the high-speed pinion 33 into use by a solenoid or an electro-fluid pusher 66. A switch to actuate the latter and ensure de-energization of the motor 14 during change of clutch consists of a pivoted lever 70 the location of a dependent catch 74 on which either above or below a fixed rim 73 determines the direction of movement of the pusher 66. Transfer of the catch 74 from one to the other of these positions can be made only when the lever 70 is rotated horizontally to a position in which the motor 14 is cut off, a gap 75 in the rim 73 here allowing the transfer.

IPC: B29D23/00
Filed: 1974-04-22
Abstract: 1471783 Seaming YOSHINO KOGYOSHO CO Ltd 22 April 1974 [23 April 1973] 17562/74 Heading B5K [Also in Division B8] A collapsible tube comprises a laminated body 4 formed from at least two thermoplastics layers 5 and 6, one of which is impermeable, and a nozzle head 2 which is press-formed from a laminated disc comprising at least two thermoplastic resin layers 16 and 17, one being impermeable, and which is welded to the tube body such that the impermeable layers 6 and 16 are in overlapping contact, Fig. 6B (not shown), or in edge-to-edge contact to form a continuous barrier layer across the body/head joint. The head is formed by cutting the disc from a laminate of at least the two layers 16 and 17 by means of a cutter sleeve 7, which, together with a mould core 9, supports the tube body. One or other of the layers 16 and 17 is in a molten state so that the latent heat of fusion causes welding of the tube body to the disc on cutting out of the latter. The disc is then pressed between the mould core and a furnace mould 13 to form the nozzle head. Contact between the impermeable layers 6 and 16 is achieved during welding and pressing of the disc. The impermeable layers may be formed of polypropylene, polyamide or poly(vinyl alcohol), ad the otherlayers 5 and 17 may be formed of polyethylene. The layers 16 and 17 may be separately extruded, welded together on cutting out of the disc, and the remnants separated and recycled, Figs. 5A and 5B (not shown). In a modification, the disc may be cut from a laminate comprising an impermeable resin layer 16, additional layers 18, and the molten resin layer 17.

Title: Improvement in brake mechanism
IPC: F16D51/24
Filed: 1943-10-27
Abstract: 576,503. Brakes. TIMKEN-DETROIT AXLE CO. Oct. 27, 1943, No. 17743. Convention date, Nov. 13, 1942. [Class 103 (i)] In an internal-expanding brake in which an actuating-lever is pivoted adjacent one end of a shoe and a fulcrum member transmits motion from the lever to the shoe, resilient means are provided between, and acting directly upon, the shoe and lever for constantly maintaining contact of the shoe and lever with the fulcrum member. As shown two such brake shoes A are positioned between abutments 41, 42 which engage faces 38, 39 on the webs 37 of the shoes. The abutment 41 of each shoe is pivoted on an eccentric portion 19 of an anchor pin 15 revoluble by a squared end for adjustment of the abutment 41 to take up wear of the lining and lockable by a nut 21. Serrations may be provided on collar 20 to engage serrations on the opposed face of the backing-plate 10, to give a positive lock. The flange 18 acts as a journal for one side member 52 of a pressure-lever, the other side member 51 of which is journalled on a smaller concentric part 17 of the pin 15. The lever 51, 52 is actuated by a cylinder D and the side members 51, 52 are slotted to clear the pin 16 carrying the abutment 42, and the two levers are connected by a retracting-spring 72. The members 51, 52 are spaced by a welded strip 54 on which bears slidably, the flat face of a presser block 74 having a curved face engaging a similarly curved recess in the web of the brake shoe which is positioned between the members 51, 52. The shoe and the presser 74 are kept in mutual contact by a compression spring 76 housed in openings in the members 51, 52 and in the shoe web. One end of the spring bears on a shallow boss 79 on the wall of the opening in the shoe web, and is thereby centred, whilst the other end of the spring bears on a plate 83 having positioning-tongues engaging in the spring and the openings in the members 51, 52, the arrangement being such that movement of the shoe circumferentially of the drum is accommodated by sliding of the plate 83. In a modification, the portions 17, 18 of the pin 15 are formed as cams so that revoluble adjustment of the pin 15 effects compensating adjustment of the lever at the same time as the abutment is adjusted. This modification is particularly advantageous when it is desired to use thick brake linings. In a further modification, the back plate is formed to ensure a free circulation of air to cool the brake cylinder.

Class 120(2) A spinning or twisting machine having haul pulleys for ensuring that yarn is forwarded at the same rate that it is delivered by the delivery rollers has the pulleys driven at a nominal speed greater than that of the delivery rollers and a slipping clutch mechanism is interposed in the drive to the haul pulleys. A fibrous strand is passed from the delivery rollers of a spinning or twisting machine through a tube 7, around haul pulleys 3 to the guide tube of a flyer driven by a rope pulley 2. Each haul pulley 3 is provided with a gear wheel 5 meshing with a normally stationary pinion 6 on the tube 7. The gear ratio is such that the strand would be forwarded by the haul pulleys 3 about 5 per cent faster than it is delivered from the delivery rollers if the pinion 6 remained stationary. Incrase in tension, however, may cause the pinion 6 to rotate against the influence of a clutch formed by two sleeves 10, 11 with conical friction faces held against a sleeve 9 by a spring 13, the effect of which may be adjusted manually by a nut 12. In another embodiment, the pinion 6 is fixed and the gear wheels 5 are separated from the haul pulleys 3 with friction 'discs interposed between the wheels 5 and flanges formed on the upper faces of the pulleys 3.

Title: Method of and apparatus for the electrical precipitation of suspended particles from gaseous fluids
IPC: B03C3/38
Filed: 1932-06-27
Abstract: In apparatus for the electrical precipitation of suspended material from gases, the discharge electrode is formed by the narrow conducting path 3 of a spark between electrodes 1 and 2. The voltage producing the spark is preferably less than the unidirectional voltage from transformer 9 and rectifier 10 which is imposed between the spark path 3 and a collecting electrode 7, this latter voltage being sufficiently high to cause the spark path to function as a <PICT:0403665/III/1> discharge electrode and set up a corona discharge between it and the collecting electrode 7 which is independent of the spark discharge.  The electrodes 1 and 2 are formed as relatively massive bodies, such as spheres or rods, and the surface of either or both of the electrodes may be covered with insulating material to promote a discharge in the form of numerous thread-like sparks. Alternating or unidirectional current, preferably at a potential of a few thousand volts, may be used to produce the spark.
