Abstract: 353,048. Indoor games. HAWORTH, T., 638, Lytham Road, Blackpool. April 11, 1930, No. 11505. [Class 132 (ii).] An indoor game comprises rotary targets which are arrested in one of a number of scoring positions by strikers whose motion is governed by a movable weight. A target is in the form of ratchet wheels 1 driven by the shaft 3 through frictional driving gear comprising washers or collars, one on each side of the wheel, resiliently pressed against the side faces of the wheel by means of helical springs mounted coaxially with the shaft. A striker comprises a head 7 in the form of an aeroplane mounted on a lever 4 fixed to a boss 5 rotatable on a shaft 6, the boss also having fixed to it the screw-threaded arm 9 carrying in the form of a nut the weight 8 movable within the limits of the stop nuts 10, 11. The head 7 is moved into its inoperative position by moving to the right against the action of the spring 22 the arm 27 connected to the arm 21 fixed to the shaft 6 having fixed to it a dog-toothed bush 20 which engages with a dog tooth 19 formed on the bush 5, and is there retained by the spring- controlled pawl 12 engaging a projection 13 on the head 7. The arm 27 is retained in its moved position by a notch 24 in it engaging a projection 25 in a gate 26. To release the striking head 7 the arm 27 is released and the plunger 15 actuated against the action of the spring 16 between the fixed member 17 and a collar 18 on the plunger to remove the pawl 12 against the action of the spring 14 from engagement with the projection 13 and allow the head 7 to rotate under the action of the weight 8 and stop the motion of the rotating ratchet wheel 1. The motion of the head 7 can be changed by altering the position of the weight 8 on the screw-threaded arm 9. The mechanism is mounted in a detachable frame 28 for removal from the casing 2.

Title: Improvements relating to the manufacture of ion exchange materials
IPC: B01J39/22
Filed: 1935-04-13
Abstract: An ion-exchange material suitable for use in softening water is obtained by treating naturally occurring decomposition products of vegetable matter, such as peat, lignite, coal and anthracite, with strong sulphuric acid or a substance having a similar chemical effect, such as sulphur trioxide, fuming sulphuric acid or chlorsulphonic acid, the reaction being terminated before there is any appreciable formation of free carbon.  The temperature of the reaction is preferably not allowed to exceed 150 DEG  C.  The product may be rendered plastic for moulding by admixture with finely divided material, such as infusorial earth, which is added before, during, or after the reaction.  Substances such as cellulose xanthogenate or silica gel, which coagulate in contact with water or acids, may also be added.  The Specification as open to inspection under Sect. 91 mentions pumice stone, clay, cork and activated carbon as substances which may be used in admixture with the reaction product.  This subject-matter does not appear in the Specification as accepted.ALSO:An ion-exchange material suitable for use in softening water is obtained by treating naturally occurring decomposition products of vegetable matter, such as peat, lignite, coal and anthracite, with strong sulphuric acid or a substance having a similar chemical effect, such as sulphur trioxide, fuming sulphuric acid or chlorsulphonic acid, the reaction being terminated before there is any appreciable formation of free carbon.

Abstract: 251,661. American Cable Co., Inc., (Assignees of Briggs, A. J.). May 2, 1925, [Convention date]. Machines for making.-In apparatus for bending wire into helices and laying the helices into a strand, rope or cable, the wire, which is bent by passing it around rolls mounted in staggered relation upon a carrier rotatable about an axis at right angles to the axes of the rolls, is fed from a series of reels 6 to each of which is given a planetary motion. The supply reels 6 aremounted in supports 9 carried in a frame 10, 11 which rotates with the helix-forming head and the supports 9 are rotated so as to rotate the reels 6 at right angles to their own axes by cranks 15 mounted upon a ring 17 which rotates with, but eccentrically of the shaft 5 carrying the reels. The forming head A comprises a corresponding number of independently mounted rotatable carriers 21 upon which are mounted the bending rolls 18 - - 20, the wires passing through the hollow trunnions 28 of the carriers and between the bending rolls. Upon issuing from the forming head the wires are laid about a core 46, the strand or rope thereby formed being drawn through a bushing 44 by any form of drawing- off mechanism. The middle bending roll 18 is preferably adjustably mounted in a slot 23, Fig. 5, so as to allow of variation of the diameter of the helix formed. The carriers 21 and the shaft 5 are driven independently from a lay shaft 41 by spur gearing which permits variation of their relative speed to vary the pitch of the helices formed. Brakes 50 are provided for tensioning the wires issuing from the reels 6. Specification 206,605 is referred to.
