Title: Tip for foundry core blast pipe
IPC: B22C15/24
Filed: 1976-04-09
Abstract: A tip for a pipe of the type used in foundries for the fabrication of molds and sand cores by sand blasting in an appropriate foundry installation is made of plastic material and has its exterior portion in the form of an essentially cylindrical part on the side connected to the blast pipe and of a coupling cone in one of the filling holes of the core molds on the other side of his pipe. It is distinguished by the fact that this coupling cone is connected to the essentially cylindrical external portion by an elastically supported essentially circular shoulder on the upper wall of the core mold, thus achieving a tight fit by exerting a horizontal thrust on the core mold. Application to mass production of sand cores by blasting, particularly by means of rigid metal blast pipes, is attained through this invention.

Patent ES-466621-A1 (ES)
Title: Noise reducing control valve for a hydraulic brake booster
IPC: B60T15/04
Filed: 1978-02-03
Abstract: A hydraulic brake booster operatively connects with a pressurized fluid source and a master brake cylinder to convert the pressure within the pressurized fluid source to a power assist to the master brake cylinder during a brake application. The booster includes a cylindrical housing defining a bore and a piston is slidably mounted in the bore to define a pressure chamber and to operatively connect with the master brake cylinder. A valve member is slidably disposed within a bore within the piston and is movable upon a brake application to communicate the pressurized fluid source to the pressure chamber which urges the piston into engagement with the master brake cylinder. In a rest position inlet and outlet openings on the piston communicate fluid through the piston without any transfer of the force within the pressurized fluid to the piston. Upon movement of the valve member, a land on the valve member cooperates with the piston bore to restrict communication between the inlet and outlet openings which concurrently increases the communication to the pressure chamber and increases the pressure therein. Consequently, the piston is pressure responsive to move relative to the housing to engage the master brake cylinder to assist in a brake application. The valve member land includes a first diameter portion and second diameter portion and a recess between the portions to cooperate with the piston bore to quietly restrict the communication between the inlet and outlet openings.

Title: Pneumatic tires for vehicle wheels
IPC: B60C9/26
Filed: 1978-06-23
Abstract: A pneumatic tire for motor vehicles having a generally trapezoidal section with a top portion which is generally convex towards the outside and wider than any other part of the tire, beads, and two sidewalls. The sidewalls spread outwardly from the beads to zones which connect the sidewalls with the top portion. The top portion has a central tread portion which is normally in contact with the ground when the tire is under load, and lateral shoulders which are spaced from the ground during rectilinear running of the vehicle. The sidewalls have zones which are less resistant to bending adjacent to the shoulders and adjacent to the beads than the parts which are intermediate the shoulders and beads. The less resistant zones act as hinges under load on the tread. A generally annular reinforcing structure for the tread, which is substantially inextensible in the axial and circumferential direction, is folded at its ends about reinforcing annular straps arranged in each shoulder. In any radial section, the cincture connection angle, which is the angle between a straight line drawn through the center of the hinge adjacent to each shoulder and parallel to the tire axis and a straight line drawn through the center of the shoulder hinge and the center of the strap, is between -10 DEG and 30 DEG .

Title: High-pressure sodium vapor discharge lamp
IPC: H01J61/073
Filed: 1980-05-26
Abstract: High-pressure sodium vapor discharge lamps having a color temperature of 2250 to 2750 K. and a color rendition index Ra of 60-85 emit light of a strongly reduced Ra already after approximately 2000 hours in operation. As compared with the life of normal, yellow high-pressure sodium vapor discharge lamps, this period is very short. The discharge vessel contains sodium, mercury and a rare gas, the weight ratio Na/Hg being from 1/1 to 1/9 and the sodium pressure during operation of the lamp being from 4x104 to 10.7x104 Pa. The rare gas pressure in the discharge vessel at 300 K. is between 1333 and 1333x102 Pa. By using an emitter which contains oxygen-bound strontium and oxygen-bound tungsten in a molar ratio from 3/1 to 50/1, the initial properties of such white-light-producing lamps are maintained for a long period of time.

Title: New compounding formulas for rubber-metal adhesion (use of cobalt propionate) in tines.
IPC: C08J5/10
Filed: 1981-05-07
Abstract: This invention is directed to a rubber skim stock and a product containing the skim stock having improved adhesion between a brassed or zinc coated metal member and contiguous rubber skim stock.
