Patent GB-346976-A (GB)
IPC: B41B1/00
Filed: 1930-04-01
Abstract: 346,976. Type making machines. KAISHA, N. T. K., 1, Itchome, Minamidenma-Cho, Kyobashi-ku, Tokio-Shi, Japan. April 1, 1930, No. 10335. Convention date, May 3, 1929. [Class 100 (iii).] Single-type composing and casting machines; matrices.-A machine for composing and casting Japanese or Chinese characters is provided with separate matrix-bars 4, Figs. 2 and 5, suspended in a frame 11, in which individual bars are movable vertically to position a selected character in front of the mould 39. The matrix-frame 11, shown in plan in Fig. 1, is movable in two directions at right-angles to effect the selection of a matrix-bar. The frame is moved to right and left, to bring a particular row of bars into use, by means of a sliding index-board 3, which has a handle 53 and is geared to the matrix-frame, the board being divided into five sections corresponding to the five rows of matrices. The matrix-frame is moved forwards and backwards, to select a particular bar of the row, by means of a handle 14, to which is connected an index-bar 15 containing an aperture 17, which moves over indicating characters on the indexboard. Movement of the handle 14 to right or left over the particular section of the index-board that contains the indicating-characters corresponding to the selected matrix-bar serves to position the required matrix on the bar. This is effected by a lifting-member 36, Fig. 2, which is operated by a lever 32 under the control of a cam 26. The height to which the lifting-member rises is determined by a horizontal sliding bar 21 having a stepped portion, the bar being adjusted by the movement of the handle 14 to right or left.

Title: Improvements in or relating to wireless direction finding apparatus
IPC: G01S1/02
Filed: 1932-04-14
Abstract: 378,831. Directive wireless signalling. TELEFUNKEN GES. FUR DRAHTLOSE TELEGRAPHIE, 12, Hallesches Ufer, Berlin. April 14, 1932, No. 10749. Convention date, April 14, 1931. [Class 40 (v).] For correcting the pointer readings of a radiogoniometer &c. for quadrantal and other errors, a parallelogram drive is used between the rotating member and the pointer in which the transmission ratio of the drive is substantially unity or greater than unity. In one embodiment, Fig. 4, the parallelogram drive comprises the pointer z moving over scale a, the driving member p attached to the rotating member of the direction finder, and members z<1> and p<1> parallel thereto, p<1> being adjustable in length by a nut s. The pointer z and driving member p are independently pivoted at o and near the pivotal joint o<1> between members z<1>, p<1> is a roller r bearing on a fixed cam k shaped to give the appropriate corrections to the pointer readings. The ratio of the movement of the pointer z and the roller r is made substantially unity by making the pivotal joint u between the pointer z and member p<1> as near to the pointer tip as possible and positioning the roller r as near as possible to the pivot o<1>. In a modification, Fig. 7 (not shown), this ratio is made greater than unity by extending the member z<1> beyond the point o<1> and mounting the roller r at its extended end. The cam k may be made easily detachable for the substitution of other cams for correcting for other wave-lengths or draughts in the case of shipboard installations. These cams may be cut from blanks M, Fig. 6, with a basic circle ko graduated in degrees with a family of arcs 1 of radius z\ Fig. 4, passing through these graduations. On these arcs are set out experimentally determined errors and a curve drawn to connect these points, the cam being cut to correspond thereto. The blanks are provided with positioning holes n, x. A known device for error correction is also described in which the pointer z, Fig. 2, is moved from the driving member p through a curved arm b bearing a roller r engaging a fixed cam k.

Title: Improvements in resilient wheels
IPC: B60B9/28
Filed: 1923-04-20
Abstract: 219,098. Schultz, E. April 20, 1923. Spring wheels with continuous outer rigid ring and pneumatic and like hubs and cushions.-A resilient wheel comprises a number of cylinders 7 communicating with an annular casing 9 which surrounds but floats clear of the hub 1. A double piston works in each cylinder, and comprises a hollow main piston 11 fitting the cylinder 7, and a pumping piston 31 closed at both ends and working in the piston 11. A spring 35 tends to force the pistons apart. The outer heads of the cylinders 31 bear against corresponding concave portions 33 of a ring 34, which may be built up of sectional members strengthened by webs 39. The pistons 11 have flanges bearing against concave surfaces 6 formed in rings 5 held by the inturned edges of discs 2 secured to the hub. A rubber ring 25 is interposed between the inner ends of the pistons to cushion shocks. In use, the pistons 31 move outwards under action of the springs 35 and centrifugal force, drawing in air through ports 30 and a valve, 28 to the space between the pistons. As each piston comes round to the bottom of the wheel, it is driven inwards, forcing the air through a valve 19 into the casing 9. This process continues automatically until the air pressure in the casing 9 is sufficient to support the load. The casing 9 may be common to all the cylinders or may have partitions 40 to form a separate compartment for each cylinder.

According to the invention, the sight and gun are interconnected by flexible wire-rope transmission means. In the form shown, the sight is mounted for elevation and training on a pedestal 1 and the gun D is similarly mounted on a pedestal 2. The pedestal 1 carries a toothed sector 8 connected by a rack 7 with a sector 6 on the sight and a sector 13 on the pedestal 2 is similarly connected with the gun D. The sectors 8, 13 are carried by pulleys 11, 11a over which pass flexible cables 10, 10a. The sight support A carries a spur gear 18 engaging a pinion 19 on a crank-shaft 20 the cranks of which are connected by pistons 25, 26, 27 and wires 22, 23, 24 to similar pistons engaging cranks on a shaft 21 geared to the gun support B. The sight carries a handle 42 for controlling the motor 39 which through a gear-box 40, and pinion 41 serves to effect training movements of the gun that are reproduced at the sight.

Abstract: 205,124. Dawson, Sir A. T., Buckham, Sir G. T., and Larsson, C. A. April 18,. 1922. Machine guns. - A recoiling-barrel gun of the Vickers type is provided with a drum magazine, preferably of the Lewis type, the cartridges being deposited from the drum into a feedslide which carries them into position for engagement with the extractor of the lock. In the form shown in plan in Fig. 2, the cartridge drum B is mounted on a spigot a<2> on the front hinged cover A<2>. The recoil plate of the gun engages one arm d<3> of a bell-crank lever the other arm d' of which moves a transverse slide E<1> in the feedbox E. A third and higher arm d<2> of the bellcrank lever reciprocates a slide D which through a pin d rocks the arm C carrying the pawl C<1> for feeding the drum. The feed movement of the drum, which occurs during run-out, brings a cartridge X beneath a spring-controlled guide A<4>, Fig. 4, carried by a fixed bracket A<5>. During the recoil, the feed-slide E<1> moves to the right and a deflector spring E<2> on the slide forces the cartridge down a fixed guide e<3> on the feed-box and into the slide, the cartridge being moved into line with the extractor of the lock when the slide returns.

The bearing 5 is mounted upon ribs 6 supported by a cylindrical portion 4 which is connected to an outer casing 2 by a web 3. A retaining member 12 is secured to the member 4 and extends beyond the end of the bearing. The space between the members 4, 12 and the bearing 5 is filled with wick material 36, 38 and 14. A ining 32 of wick material is also disposed in an end shield 29 secured to the outer casing 2. Steel stiffening washers 20, 23 are provided adjacent the felt washers 19, 22, and cup washers 15, 24, cushion washers 16, 18, 25, 27 and thrust washers 17, 26 are associated therewith. A neoprene ring 21 provides an oil seal for washer 15. Lubricant introduced through a threaded inlet orifice having a stopper 34 may flow through an orifice 35 in member 4 to wick material 38, or into wick lining 32, thus reaching the felt washers 19, 22 by capillary action. The lubricant is then pumped two section 9 and returns to wick material 37 through an orifice 11 in the bearing 5. The invention is applied to a dynamo-electric machine wherein a rotor 8 is mounted on the shaft 7.
