Abstract: 368,732. Harvesting cotton. COTTON HARVESTER CORPORATION OF AMERICA, 541, Wood Street, Pittsburg, U.S.A.-(Assignees of Wirth, L. E. ; 421, Stratton Lane, East End, Pittsburg, U.S.A.) Dec. 2, 1930, No. 36316. Convention date, May 21. [Class 6 (iii).] A cotton harvester of the type in which the cotton is picked by rotary needles projecting from rotating cylinders has the needles arranged in vertical rows each row being positively and independently driven. The machine comprises a frame 101 mounted on wheels 102 and supporting two needle carrier assemblies 103 from which needles 104 project. Each assembly comprises a screen 105, a cotton chamber 106 and a grid 107 co-operating with the needles. The picked cotton is drawn from the chamber 106 through a conduit 108 to an outlet 111 by a fan 109. Each needle carrier comprises a cylinder 114 rotatably mounted on a vertical shaft 115 that is keyed to a bottom plate 118 which carries a cam track 120 for the rollers 121 of stripper bars 122. The upper cam track is carried by a housing 113. Each cylinder 114 is driven from a motor actuated worm shaft 124 through a worm gear 125 and a clutch member 126 splined on a sleeve 127 which is provided with an outwardly flared base 127a secured by bolts to the cylinder. Springs 132 normally hold the clutch member 126 in gripping connection with the gear 125 but permit slip should the cylinder 114 be held against rotation. The needles 104 are arranged in vertical rows and the needles of each row are rotated during part of each revolution of the cylinder. Each needle is mounted in a journal 135 in a bearing 134 in the cylinder and a bevel gear 136 meshing with a bevel gear 140 on a vertical shaft 137 is fixed to each journal. The shafts 137 are intermittently driven through splined clutch members 143 adapted to engage surfaces on gears 141 free on the shafts 137 but meshing with a gear wheel 142 that is driven from the worm gear 125 through a sleeve 155, pinions 154, 153 and an internal ring gear 151 fixed to the gear 125. The members 143 are depressed to clutch the shafts to the driving gears 141 by cam riders 149 engaging an annular track 147 on the base of the gear housing 113. The needles are thus caused to rotate at a high speed during the time they are presented to the cotton plants. In a modification the gear 142 may be stationary, the needles then rotating at a lower rate. The fan for drawing the cotton along the conduit 108 is driven through a clutch adapted to slip should the rotation of the fan be impeded.

Title: Improvements in or relating to fire-extinguishing sprinkler heads
IPC: A62C37/12
Filed: 1933-12-27
Abstract: 420,339. Valves. BURGESS, A. F., 10, New Court, Lincoln's Inn, London.- (Automatic Sprinkler Co. of America; 910, Standard Bank Building, Cleveland, Ohio, U.S.A.) Dec. 27, 1933, No. 36389. [Class 135] Relates to sprinkler systems wherein sprinkler heads distributed over a large area or on several floors are supplied from a common source, and consists in fitting each head with a pressure - controlled valve, whereby the outflow of water at any head is controlled, and the water pressure available at all heads throughout the system is equalized. As shown, a head 16 with a valve 44 held closed normally by an ordinary fusible strut 46, 48 is formed with a chamber 24 in which is mounted a fixed valve seat member 28 and a diaphragm 38. The latter carries a ring-shaped valve member 30 which is held away from the member 28 by a spring 36. The original position of the member 28 and the tension of the spring 36 are adjustable by adjusting the screwed ring 42. When the valve 44 is released, the diaphragm 38 will be flexed by the inflowing water, so moving the member 30 towards the member 28 to an extent depending on the water pressure available at the head. Thus, outflow of water at a head near the source is reduced, making a higher pressure available at heads more remote from the source. Complete closing of the valve members 28, 30 is prevented by lugs 39.

Filed: 1976-09-03
Abstract: 1532069 Bowden-type cable; winding coatings on core INCOM INTERNATIONAL Inc 3 Sept 1976 [5 Sept 1975] 36617/76 Heading B8G [Also in Division F2]  The metallic wire core 18 of a Bowden type push-pull remote control cable assembly has a friction reducing "PTFE resin" (polytetrafluoroethylene resin) coating, i.e. layer 24 secured to the metallic wire core 18 by an intermediate coating, i.e. layers 26 of "FEP resin" (fluorinated ethylenepropylene resin) which is securely heat bonded to the PTFE layer 24 and to the metallic wire core 18 whereby the PTFE layer 24 is securely attached to the metallic wire core 18. This method of providing a PTFE layer 24 on the core 18 via an intermediate bonded layer of FEP, thus avoids the known difficulty of direct bonding of a PTFE coating or layer to a metallic surface with its attendant subsequent failures of the PTFE layer, i.e. its detaching from the core, in service, due to the poorly effected direct bond therebetween. As shown, a finished cable core 16 includes the metallic core 18 around which a coating 20 is formed from a helically wound multi-lamina cast tape 22 comprising the outer PTFE layer 24 and the inner FEP layer 26, the inner FEP layer being heat bonded between the outer PTFE layer 24 and core 18 on the apparatus of Fig. 2. Alternatively the layers 24 and 26 may be provided as two separate tapes helically wound one on the other on the core 18. The metallic core 18 may be formed as a plurality of wire strands 30 around which flat stainless steel wires 32, with or without an axial space 36 between adjacent convolutions are wound. Alternatively the metallic core 18 may be a single phase solid wire. The process or method of applying and heat bonding the PTFE and FEP layers 24, 26 to the metallic core is effected on the apparatus of Fig. 2. As shown, the tape 22 is helically wound via a wrapper 44, around the metallic core 18 or it is unwound from a pay off spool 36 and the resulting core assembly 16 is then passed several times through radiant heated ovens 48 via a system of pulleys 52 to 58 to effect the heat bonding of the FEP layer 26 to the metallic core 18 and PTFE layer 24 after which the bonded core assembly 16 is cooled and passed to a finished take-up spool device 40. In use the core 18 operates within a conduit 12 having an internal surface nylon layer 14.
