Abstract: 154,618. Sperry Gyroscope Co., (Assignees of Sperry, E. A.). May 17, 1917, [Convention date]. Gyroscopic compasses.-Consists in means for correcting compass readings for speed, course and latitude by communicating the movements of the sensitive element of the master compass to the card of a relay dummy compass having a rotatable lubber ring which is set by the correction device. The corrected readings are transmitted from the dummy compass to one or more repeaters, and the dummy compass may also be connected to the master compass so as to correct the readings of the latter. Fig. 1 shows one form of dummy compass and Fig. 4 the master compass. The card 1 is moved in accordance with the movements of the sensitive element 73, either manually by the handle 3 or electrically by a step-by-step motor 7 actuated by contacts 8 which are operated by a pinion 82 meshing with a gear 81 on the follow-up member 68. The lubbers mark or marks 15<x> of the dummy compass are carried by a rotatable ring 14<x> which is turned by the correction mechanism. This mechanism comprises speed and latitude dials 20, 41, Figs. 3 and 6, which are set manually by knobs 21, 42. The dial 20 is formed with a spiral slot 23, Fig. 7, and is seated in a rotatable-cup 22 having a slot 24. The cup 22 also carries a bracket 29 pivoted at 30 and having at its outer end a roller 32 engaging in an inclined ring 33 secured to the card 1. A link 26 has at one end a pin 25 passing through the slots 24, 23 and is connected at its other end to one arm of a bellcrank lever 34 pivoted at 35 to a rotatable cup 36 in which the dial 41 is seated. The lever 34 carries a pin 37 passing through slots 38, 44 in the cup 36 and dial 41. The dial 41 also has an M-shaped slot 43 and the cup 36 has a slot 45, both these slots being engaged by a pin 46 on an arm 47 carried by a pivoted sector having teeth 151 engaging teeth 52 on the ring 14<x>. The movement of the ring is indicated on a scale 500<1>. The dummy compass has two transmitters comprising contacts 8<1>, 89, Fig. 3, respectively mounted on the ring 14<x> and on the fixed casing 91. The contacts 89 are connected to a motor which actuates the follower of the master compass, and the, contacts 8<1> are connected to motors which actuate the repeaters. The follower motor may also drive one part of a differential gear, the other part of which is driven by a motor controlled bv the contacts 8<1>; the central member of the differential is geared to a rotatable lubber ring on the master compass to correct the headings of the latter. The dummy compass may carry an electromagnet 61 operating an arm 63 having a finger adapted to enter a notch 64 on a collar secured to the shaft of the motor 7. The magnet is controlled by contacts 66, 67 respectively carried by a stationary part and by the card 1 so that the card can be locked in a predetermined position. A reversible motor may be employed instead of the motor 7 to rotate the card 1. Specification 15679/11 is referred to.

A sanitary towel comprising cellulose fibres enclosed in a folded cellulose wadding band and a gauze wrapper is made by grinding cellulose board, conveying the ground board in an air current to the middle longitudinal section of a moving cellulose wadding layer, holding the sides of the layer over the ground board and cutting the pad so formed into predetermined lengths. The cellulose board is fed from a reel 1 to a hammer mill 3 where it is ground, the fibres so produced being withdrawn through a duct CS by a fan 4. The fan delivers the fibres in an air current through a duct CS<SP>1</SP> to the centre of a rotating drum 5. The drum has a peripheral gap over which cellulose wadding O from a reel 7 is guided by an endless wire mesh belt 6. Fibres entering the drum pass through the peripheral gap and are deposited along the middle of the band O as it passes round the drum, the air carrying the fibres escaping through the band O and the belt 6. The part of the peripheral gap in the drum which is not covered by the band and belt during generation of the device is closed by a belt 106 moving around rollers 77, 104, 105. The wadding band with fibres deposited thereon is passed to a conveyer 94 where the uncovered side portions of the band are wrapped over the deposited fibres to complete envelope them. The band is then passed to a cutting station 143 where is cut into pad lengths T by a rotary knife 145. The pad lengths are transferred to a conveyer 15 which runs at a higher speed than the conveyer 94 so that the pad lengths are spaced from one another. The pad lengths are transferred to a conveyer 10 within a tunnel 16 which carries tubular gauze. On passing out of the tunnel on to a conveyer 150, the pads are ensleeved in the tubular gauze which is cut between the pad lengths at a second cutting station 111. The finished towels have a free portion 17<SP>1</SP> of tubular gauze at each end.
