Title: Rotary hook sewing machines
IPC: D05B73/12
Filed: 1929-01-01
Abstract: 316,506. Fairweather, W., (Singer Manufacturing Co.). Jan. 1, 1929. Lock-stitch hook sewing- machines. - In a vertical axis rotary hook sewing machine, the hook rotates more than once for each reciprocation of the needle and the bobbin carrier is given a short oscillation in a direction opposite to that of the hook by a finger. The hook 22 is formed in a member 21 rotated by the vertical shaft 15 from the bevel gears 13, 12. The gear 12 is rotated by the shaft 11 at the same rate as the needle reciprocating shaft. The gears 13, 12 are in the ratio 2 : 1 so that the hook rotates twice to one reciprocation of the needle. The hookmember encloses the bobbin carrier 17 which is held against rotation by a gap 27 therein engaging a fixed stop 29 on the cloth plate. To rotate the carrier slightly in a direction opposite that of the hook to enable the loop to clear the stop 29, a finger 30 engages the shoulder 28. The finger is mounted on a shaft 31 and is pressed against the shoulder by a spring 38. An arm 34 at the base of the shalt 31 carries a roller 36 running on the periphery of an eccentric 37 mounted on the shaft 11 to impart the necessary movements to the finger. A guard 40 is provided to prevent the fouling of the " chained-off " stitches by the hook. The bobbin carrier has a loop spreading finger 25.

Title: Process for the manufacture of trisazo dyestuffs for dyeing cotton
IPC: C09B31/18
Filed: 1925-01-01
Abstract: Trisazo dyes are produced by coupling a diazo compound of the benzene or naphthalene series with a second component of the naphthalene series, rediazotizing and coupling again with a second component of the naphthalene series, and finally diazotizing and coupling with a 1-aryl-aminonaphthalenesulphonic acid.  The products dye cotton directly in grey, blue-grey, or black shades fast to light and washing.  According to examples 1-phenylaminonaphthalene-8-sulphonic acid, or Cleve's 1-phenylaminonaphthalene-sulphonic acid, is coupled with the diazo compounds of the following amino-disazo dyes:-a -naphthylamine or Cleve's acid or p-aminoacetanilide--> Cleve's acid --> Cleve's acid, 1-methyl-2-aminobenzene-4-sulphonic acid or p-toluidine --> Cleve's acid --> Cleve's acid, 1-methyl-2-aminobenzene-4-sulphonic acid --> a -naphthylamine --> Cleve's acid, Cleve's acid --> Cleve's acid --> a -naphthylamine. The Specification as open to inspection under Sect 91 (3) (a) refers to the use of second components generally as middle components.  This subject-matter does not appear in the Specification as accepted.

Abstract: An aquaculture unit has an annular vessel for fish or fry, with a filter arranged centrally.  The flow of water is partially circulatory around the filter and partially toroidal with an ascending flow at the filter.  This is achieved by mixing water with compressed air at the transition between filter and base.  Helicoidal guide vanes between and outer and an inner wall in the filter control the aerated and hence lighter water.  Excrement and filter skin are each collected separately. <IMAGE>

Abstract: In a method for production of sulphur dioxide by burning of sulphur, the combustion gas formed in a primary combustion zone is subjected to an afterburning with secondary air, which is preheated by heat exchange with the gas in the primary combustion zone, and the ratio between primary air and secondary air is reduced as the temperature increases in the primary combustion zone. This achieves a stable sulphur burning and a reduced sulphur content of the combustion gas. <IMAGE>

Title: Improved control arrangement for reversing electric motors
IPC: H02P23/00
Filed: 1955-01-04
Abstract: 764,399. Control of A.C. motors. GENERAL ELECTRIC CO. Jan. 4, 1955 [Jan. 4, 1954], No. 245/55. Class 38(3) Relates to a reversing system for a splitphase induction motor having a squirrel cage rotor with a pair of field windings 3, 4, each of which may be used alternatively as a starting and running winding. The motor is started from rest in one direction by engaging switch 8 with terminal 10 so that winding 4 becomes the main winding. A second circuit is completed through arm 21 and contacts 29, 31, of a speed and direction-responsive switch to capacitor 39 and winding 3. When the motor reaches full speed the contacts 29, 31 are opened to interrupt the starting winding circuit. To reverse the motor, switch 8 is moved to engage terminal 9 thereby completing the main winding circuit through winding 3 and actuating a relay 14 so that arm 21 engages contact 26. The starting winding circuit is now made through capacitor 39, contacts 28, 30, and winding 4 so that reverse-current braking takes place until the motor is brought to a standstill and starts rotating in the opposite direction. Upon the motor reaching full speed in the reverse direction, contacts 28, 30, are separated to open the circuit of the winding 4. Movement of the switch 8 from engagement with terminal 9 to a neutral position causes a closed braking circuit to be established, this circuit comprising winding 3, capacitor 39, contacts 29, 31, and winding 4 connected in a loop. In another arrangement, the reversing switch is of the doublepole, double-throw, type'and the relay 14 is dispensed with Fig. 2 (not shown). In further embodiments employing single-pole reversing switch, the speed and directionresponsive switch comprises two sets each having a member for actuating the movable contacts of two pairs of co-operating contacts. These two members, which are similar to the pivoted actuating member 17, are adapted to move in opposite directions upon a given direction of rotation of the motor, Figs. 3, 4, (not shown). In one of the last embodiments, a relay having a coil carrying the motor current is adapted, when de-energized, to close a series braking circuit including the two windings of the motor.
