Title: Improved means for protecting surfaces from ice formation
IPC: B64D15/16
Filed: 1945-05-05
Abstract: 591,374. Preventing formation of ice on aircraft surfaces. DUNLOP RUBBER CO., Ltd., ANDERSON, J., and FIELD, E. F. May 5,1945,No.11464. [Class 4] Means for supplying de-icing liquid to an aircraft surface 11 comprises two superposed layers 1, 2 of absorbent material, such as fabric, the external superficial areas of the layers being sealed and their edges 5 unsealed and the layers being united along each of two zones 3 by at least one row of threads of resilient material, such as rubber, to form a conduit 4 for the de-icing liquid parallel to the edges 5. The upper surface of layer 1 and the undersurface of the layer 2 are rubberized or coated with rubber, thus confining the liquid to the conduit 4 and permitting its escape only through the yielding sides of the conduit and the unsealed edges 5. The resilient threads allow separation of the layers along the sides of the conduit and prevent too great a pressure rise with increase in viscosity of the liquid at low temperatures. The rubber threads are passed round the weft threads of the fabric and may be provided. with a cotton covering to prevent chafing. The layers may be connected by an interlacing of the constituent threads of the fabric between the zones 3 and the unsealed edges 5. According to the Provisional Specification, the resilient threads may be made of nylon, silk or " Lastex " (Registered Trade Mark). Specification 552,439 is referred to.

Title: Improvements in the catalytic manufacture and production of acetone from acetylene
IPC: C07C45/26
Filed: 1929-04-13
Abstract: 330,350. Johnson, J. Y., (1. G. Farbenindustrie Akt.-Ges.). April 13, 1929. Grant of Patent opposed. Acetone; acetaldehyde; acetic acid. - In the catalytic manufacture of acetone by the interaction of acetylene and steam, the reaction products, which may contain products other than acetone, are passed at a temperature of about 350-500‹ C. and at a moderately high velocity over a catalyst consisting of or comprising a metal, the acetate of which yields acetone when heated, or an oxide or other compound of such a metal; in this way, the products other than acetone, particularly acetaldehyde and acetic acid, and the unchanged acetylene, are converted into acetone, while the acetone already formed remains unchanged. The reaction products to be treated may be partially or completely condensed and revapourized, if desired, and fresh. acetylene and steam may be added thereto. Suitable catalysts are alkaline-earth oxides, magnesium oxide or carbonate, the oxides of manganese, zinc, tin, chromium, and aluminium, mixtures of chromium and aluminium oxides, and other heavy metal compounds, preferably mixed with alkalineearth compounds. The catalysts are preferably used in admixture with heat-conducting materials, such as rings of aluminium, iron, or chromenickel stel. The process may be conducted with three or more reaction furnaces in series, the catalyst in the furnace or furnaces not in use being regenerated, for instance with moist air. According to the example, a mixture of acetylene and steam is led over zinc oxide at 400‹ C. at a velocity of 700-800 litres per hour per litre of catalyst, and the products, which include acetaldehyde and acetic acid, are similarly treated at the same velocity in a. second furnace.

Title: Improvements in or relating to the application and clamping-on of the inner and outer end elements of sliding-clasp fasteners
IPC: A44B19/60
Filed: 1949-04-30
Abstract: 658,033. Sliding clasp fasteners. NAGELE, K. F. April 30, 1949, No. 11585. [Class 44] A machine for applying the upper and lower stop members to sliding clasp fastener tapes comprises two magazines 4 supplying the different members from sorting drums 2, 3 to reciprocating plunger presses 5 each plunger being adapted to move a stop member forward against an abutment 5a and to hold it there with a light pressure while the tape is inserted, a clutch then being engaged to cause the plunger to continue its forward movement to secure the member on the tape. A shaft 7a driven, e.g. by an electric motor through a pulley 12, has freely mounted thereon eccentrics 7 to operate the spring loaded plungers. Each eccentric may be connected to the shaft when desired by a clutch consisting of a helical spring 8 closely fitting the shaft, and having one end engaged in a bore in the eccentric and the other end in contact with an arm 9 displaceable by a press-button 10. The spring stiffness and size is such that when the arm is held by the arm 9, the plunger has moved forward, carrying the final member in the magazine against the abutment 5a and holding it with a light pressure. After insertion of the tape, the button 10 is pressed, the spring 8 binding on the shaft to rotate the eccentric projecting the plunger to clamp the member in position. After this movement the plunger returns, receives another member and moves it against the abutment, the end of the spring then contacting the arm 9 again to release the clutch. Any other suitable clutch may be used. To prevent the members sticking in the magazines they are vibrated by hammers. In the form shown the hammers 18 are actuated by air pressure transmitted by a pipe 16 from a cam operated piston 14. Alternatively an electromagnet supplied with alternating current may be used. The drums 2, 3 are rotated by a belt from a pulley 11..
