Title: Improvements in or relating to devices for transforming rotary motion into linear motion, or vice-versa
Inventor: COX ALAN JOHN
IPC: F16H25/22
Filed: 1956-07-07
Abstract: 861,279. Screw-and-nut gearing. BIRMING- HAM SMALL ARMS CO. Ltd. July 4, 1957 [July 7, 1956], No. 21117/56. Class 80 (3). In a screw-and-nut mechanism engagement between the grooves 20 of the screw 19 and the nut 23 is effected through balls 32, corresponding to the number of starts of the thread and carried by a cage 33, which roll around an annular groove 31 in the nut member 23. The ratio of linear movement to rotary movement is thereby reduced compared to a conventional screw and nut. The walls of the screw grooves and the walls of the nut groove may be provided at different angles so that a different rate of movement can be obtained in one direction of movement to the other. The screw helix may be irregular.

Title: Method of improving the surface of board material and products
IPC: B27N3/00
Filed: 1964-05-22
Abstract: Fibreboard and like material is surfaced by applying to a lap of wet fibre on a porous surface such as a Fourdrinier wire an aqueous suspension of material obtained from bark, dewatering the mass and then drying or hot-pressing to obtain either a porous or a hard board.  The bark material is obtained by mechanical defibration or chemical treatment with sodium hydroxide or sulphide.  Wood fibre, inorganic fibres such as glass fibres, or synthetic organic fibres may be included, together with water-soluble, non-corrosive inorganic salts such as aluminium, ferrous, or potassium sulphate, aluminium or ammonium phosphate, or aluminium chloride which serve as pH buffers. Other additions specified are gypsum, potassium titanate, and binders such as phenol-, urea-, or melamine-formaldehyde resins.

Envelopes. - A reply envelope, of the kind having a window aperture for exposing the address on the enclosure, is provided with an address flap disposed inside the envelope in such a manner that it can be positioned when desired to expose an inscription thereon through the aperture. In the example shown in Fig. 2, the address flap 6, bearing the name and address of the sender, is secured at its upper edge to the inside of the envelope body along the corresponding edge of the aperture 5, and can be turned inwards tc allow the address of the receiver, written upon the enclosure, to be revealed through the aperture. To return the envelope to the origianl sender, the address flap is turned down to expose the address thereon. The envelope is secured by the engagement of a tongue 2 on the closing-flap with a slit 3 in the envelope body. In another construction, shown in Fig. 7, the address flap 8 is preferably integral with the envelope which is formed by folding along the lines 11, 11<a> and securing at the gummed flaps 12. Thus formed the envelope has two compartments, and an address upon an enclosure in the front compartment could be revealed through the aperture 7a, while the sender's address upon the flap 8 would be covered. The envelope is secured by inserting the flap 14 between the address flap 8 and the back 15 of the envelope.

Abstract: 631,947. Lathe &c. details. SKODA WORKS, PLZEN. July 24, 1946, No. 22084. Convention date, March 7, 1942. [Class 83 (iii)] Mechanism for limiting the feed motion in a lathe or other machine tool comprises a stop member on a rotatable stop drum and a stop lever which is brought into the path of the stop member by an auxiliary control drum provided in the feed drive. In an arrangement for limiting the traverse of a lathe saddle, a toothed wheel 2, secured to the feed pinion shaft 1 (Fig. 2, extended view in plane of paper for convenience), drives a stop drum 60. A number of adjustable stops 32 are provided in different planes on this drum and one of these is adapted to strike against the end of a selected lever 45 which is rotated into the path of the stop by a spring 5, the other end of the lever bearing against an adjustable ring member 4 on an auxiliary control drum 61. A gap in the ring adjusted previously into a predetermined position allows the lever to rock over at the desired moment to stop rotation of the drum 60 and thus limit the traverse movement of the saddle. A number of levers 45 equal to the number of stops on the drum 60 are provided and the drum' 61 is driven at a slower speed than the stop drum 60, either from the pinion 1 or from a separate pinion 7 meshing with the feed rack 6. Selector mechanisms.-A further control device for the levers 45 comprises a shaft 10 against which extension pieces, Fig. 1, on the levers bear, this shaft has flats arranged at predetermined positions around its circumference and a lever can only operate to stop the feed when its extension piece is adjacent a flat. The shaft 10 may be rotated by a hand lever or may be geared to rotate with a turret to stop the traverse at selected points according to the turret tool operating.
