Abstract: 404,481. Gear-cutting. GROVES, W. W., 30, Southampton Buildings, London.- (Sykes, W. E.; Buffalo, New York, U.S.A.) Feb. 24, 1933, No. 5689. [Class 83 (iii).] In a method of generating " hour glass " worms and the like, such as worms for motorcar steering gears, a pinion cutter 1 is located so that its teeth 4 are substantially parallel to the thread to be generated on the blank 7, the cutter and blank being continuously rotated in timed relation and slowly moved relatively in a curved path 10 between the dotted and full-line positions shown in Fig. 4 during the generation of the thread. One side of the worm thread 12 is completely generated during the approach movement of the blank to the cutter along the path 10 and the opposite side is completed during the separation of the blank and cutter. The cutting speed may be 80-100 feet per minute with a high-speed steel cutter or about 150 feet per minute with a tungsten or tantalum carbide tool. In a machine embodiment, Fig. 5, the blanks 7 may be mounted on a turret 17 whose axis 16 is the axis of the curved path 10, the blank axes being inclined to the turret axis at the required helical angle 15, Fig. 4. A cutter is mounted at each of the stations 7B-7D, each cutter being carried by a housing 22 pivoted at 23 to adjust the depth of cut. The turret is moved slowly while the work pieces are traversed past the cutters and is then quickly indexed to transfer a blank to the next station. A first roughing cut is taken at station 7B, a second roughing cut at 7C, and a finishing cut at 7D, while the station 7A is for loading and unloading, the blank spindle at this station being stationary. The indexing mechanism may be of the type described in Specification 268,802, [Class 83 (iii), Metals, Cutting]. U.S.A. Specification 1,426,680 also is referred to.

Filed: 1953-03-03
Abstract: 743,003. Telescopic umbrellas. HAUPT, H. March 3, 1953 [March 15, 1952; April 26, 1952; July 4, 1952], No. 5918/53. Class 134. A telescopic umbrella having a main slide in the form of a sleeve which carries a locking member or pawl which in the open and closed condition is adapted to engage in notches or openings in the umbrella stick to retain the umbrella in both its open and closed position, is characterized in that the locking member or pawl which is pivotally mounted on the main slide is automatically disengaged from its lower locking position, i.e. the closed position of the umbrella, on shortening or telescoping the umbrella and the slide is thereafter displaceable further towards the handle end of the stick. In the embodiment shown the locking pawl 1 is mounted on a pivot pin 7 inserted in holes in the side walls of a lateral extension 6 of the sleeve 5 of the slide 2 and is engaged by a spring 12. The extension 6 is open at the top and bottom and towards the inside of the sleeve, and may alternatively be formed by two plates made integral with the sleeve 5. The pawl 1 has a lever arm 10 provided with a button 11 and a locking nose 17 adapted to engage a notch 15 in the lower portion 4 of the stick which also comprises an upper portion (not shown) of larger diameter into which the portion 4 telescopes. An inclined surface 16 is arranged adjacent the notch 15 so that when the umbrella is telescoped the nose 17 meets this surface and moves the pawl 1 out of the locking position. Alternatively the notch 15 may be extended downwardly in the form of a short slot in which the nose 17 slides until the button 11 engages the edge 18 of the handle 19 and moves the nose 17 out of the slot. Guide surfaces 21 are provided in the handle 19 to bring the slide 2 to a central position relative to the stick portion 4 against the pressure of the pawl spring 12, and the extension 6 slides on further guide surfaces (not shown) to prevent twisting of the slide. The stick portion 4 is hexagonal in cross-section or of circular section with a flat thereon and the notch 15 is provided in a flat side, which also provides a guiding surface for the locking nose 17 in its movement below the notch and further facilitates correct alignment of the nose 17 with the notch 15. Alternatively the locking nose 17 may be guided in longitudinal grooves provided in stick portions of circular cross-section, in which case the notch 15 is formed by an opening in the bottom of the groove.

Patent GB-1570311-A (GB)
Title: Treatment of cellulosic materials
IPC: B27K3/50
Filed: 1977-02-11
Abstract: A wood treating impregnant is deposited in wood by a non-aqueous wood treating system that has the ability to control the distribution, to immobilize and to more permanently fix the impregnant in the wood. The wood is treated with a liquid carrier containing the impregnant and a reactive solvent so that both the impregnant and reactive solvent penetrate into the wood. The reactive solvent is soluble in the liquid carrier and the impregnant is substantially insoluble in the liquid carrier but soluble in the reactive solvent. After the impregnant, reactive solvent and liquid carrier have penetrated the wood, the reactive solvent is reacted to become a nonsolvent for the impregnant. Since the impregnant is no longer soluble in the reacted reactive solvent, the impregnant is immobilized in the wood and, therefore, is unable to bloom. After the reaction, the liquid carrier and optionally the reacted reactive solvent are recovered from the treated wood which is clean and need not be washed.
