Abstract: 554,244. Magnetic compasses. BENDIX AVIATION CORPORATION. Dec. 24, 1941, No. 16656. Convention date, Jan. 23. [Class 97 (ii)] Relates to a direction indicating device for a craft whereon a compass is mounted and is subject to errors due to the effect of the vertical component of the earth's field upon soft iron masses aboard the craft and consists in mounting parallel Flinders bars for independent revolution about the pivot axis of the compass. The device is capable of adjustment to give a compensating effect equivalent to a single Flinders bar located on an axis other than the fore and aft axis of the craft without incurring practical difficulties such as may occur in the use of a single Flinders bar As shown, a pair of Flinders bars 10, 11 secured to gear rings 17, 18 may be independently adjusted around the vertical axis of the compass card 13 by means of knobs 23, 24. The bars are provided with pointers 29, 30 registering with a scale of degrees 31. Assuming that all compensation for quadrantal deviation, and semicircular deviation resulting from the sub-permanent magnetism of the ship has been effected at the equator and the ship brought to some North magnetic latitude, the bearing of maximum deviation is ascertained and the ship is headed along this course. The Flinders bars 10, 11 are then adjusted until the compass error is compensated.

Title: Improvements in Mechanism for Making Tips of Stays or Stiffeners for Wearing Apparel.
Inventor: SMITH FREDERICK EPHRAIM
IPC: B21D53/46
Filed: 1918-10-21
Abstract: 122,161. Smith, F, E., and Curnan, F. W. Oct. 21, 1918. Cupped articles.-A machine for making tips for stiffeners of wearing apparel consists of combined slitting mechanism and a doubleacting power press. A relatively wide metal band 27 is drawn off a drum 23, and passed through a guide 24 to a pair of slitting rollers 18, 19 having interlocking angular ribs 25 by which the band is cut into a series of narrow blank strips 26, Fig. 4, the trimmed edges 38 curling up out of the way, while the strips themselves pass through another guide 28 to feed rolls 16, 17 which carry through a further guide 29 to the tip forming mechanism. This consists of a die block 30 supporting an upper die 31 with one opening, and a lower die 32 made in two parts and provided with a series of slots 40. The upper die has inclined surfaces 36 up which the strips pass to the punches. There are an outer blanking punch 34 carried by an outer slide 12, and a series of inner form:ng ones 35 carried by an inner slide 13. The blanking punch, which is made in two parts and prcvided with a series of slots 40a and with a series of convex scallops on its front and rear faces, first operates, as shown in Fig. 6, to co-operate with corresponding concave recesses in the end of the upper die opening so as to cut off the strips :o the length required and also to form the ends with convex curves. After this, the series of blanking punches descends, as shown in Fig. 7, and forces the blanks through the slots 40 in the lower die and thereby shape each small blank 41 to the form shown at 42. These formed pieces then fall down through the die block. The short end scraps of metal 37 are blown away by a puff of air delivered from a pipe 39 having a widened nozzle. The press is operated in a known manner, and the rolls are actuated intermittently from the main shaft bv a ratchet feed and gear wheels 21. 22 and an idler 20.

Title: Method of and apparatus for reducing the gas pressure in locks for the discharge of solid materials from chambers under elevated gas pressure
IPC: C10J3/34
Filed: 1955-06-16
Abstract: 774,632. Discharging ash &c. METALLGES AKT.-GES. June 16, 1955 [Aug: 17, 1954], No. 17428/55. Classes 51 (1) and 51 (2). The gas pressure in a discharge lock associated with a pressure gas generator is reduced by scrubbing and cooling the gas with water prior to discharge from the lock through a pressure reduction valve. As shown, ash from the rotary grate 2 of a generator 1 has passed to the lock 4 and the lock cone 7 has been replaced so that the gas within the lock 4 is under pressure but isolated from the generator. Associated with the lock is a tank 11 which is filled with water from a supply 18. A valvecontrolled pipe 15 is provided for the discharge of dust-laden water whilst a pipe 14, having a pressure reduction valve 16, conducts away the cooled and purified gases. In the filling of tank 11 with water the pipe 14 acts as an overflow. In the pressure-reducing operation, the valve 16 is opened and gas from the lock passes through the pipe 12 to bubble up through the water to the pipe 14. When the gas flow has ceased, the lock cone 6 may be raised and the ash discharged. Re-establishment of the pressure in the lock after the ash discharge operation is effected by gas or vapour admittance through a valve-controlled pipe 21. In order to hasten the gas reduction process when the lock gas is predominantly non-condensable, the valve 17 in the pipe 15 is opened in addition to the valve 16. The capacity of the tank 11 is such that evaporation of the water will not occur. To aid the latter aim fresh water may be supplied through the pipe 18 and dust-laden water drawn off through the pipe 15 during the gas reduction process. In another embodiment, the lock gas is not passed through a water column in tank 11 but brought into contact with atomized water. The invention may be applied to processes other than gas generation in which solid material is discharged with the aid of the lock from a chamber under elevated gas pressure.

Each numeral wheel consists of two metal cups 4, 5, Fig. 1, joined at their peripheries and surrounded by a plastic moulding 6 bearing the numerals, Fig. 2. The units wheel 1 has at one side transfer teeth 7 between the numerals " 9 " and " 0 " and at its other side transfer teeth between the numerals " 3 and " 4," " 4 " and " 5," " 5 " and " 6," " 6 " and " 7," and " 9 " and " 0," which teeth co-operate with a pinion 8, Fig. 1, on a spindle 9. The tens wheel 2 has transfer teeth between the numerals " 9 " and " 0," " 0 " and " 1," and " 5 " and " 6," which co-operate with a pinion 14 on the spindle 9. Transfer is effected in the normal manner by the teeth on the left of the units and tens wheels up to the reading " 359 " when a cam 24 carried by the hundreds wheel 3 effects an axial movement of the spindle 9 so that the transfer teeth on the right side of the units wheel become effective. A shield 26 on the hundreds wheel extends over the tens wheel and bears the numeral " 0 which at this time obscures the numerals " 6 to " 9 " on the tens wheel and prevents a false reading. When the units wheel thereafter moves from " 9 " to " 0 " the tens wheel moves from " 0 " to " 1 " and the hundreds wheel from the second " 0 " to the third " 0 " and the spindle 9 is returned by the spring 25.
