Patent ES-451932-A1 (ES)
Title: Method of producing dry acrylamide
IPC: C08F/
Filed: 1976-09-28
Abstract: Dry acrylamide is produced by reacting acrylonitrile with from 0.3 to 1 mole of water in the presence of a metallic nitrile conversion catalyst. The reaction is conducted under conditions of pressure and temperature and other reaction conditions to convert at least 30% by weight of the nitrile to acrylamide. This reaction produces a solution of acrylamide dissolved in nitrile which then is either treated by means of cooling or pressure reduction to precipitate acrylamide crystals from the reaction mixture, which crystals are then recovered.

Patent ES-461682-A1 (ES)
Title: Double disc gate valve with replaceable spacer ring
IPC: F16K3/14
Filed: 1977-08-17
Abstract: The gate (26) of the valve has a pair of identically shaped closing discs (100, 102), the annular hardened seating surfaces (104) of which come into closing contact with a valve seat (56). During the opening and closing of the valve, tongues on the sides of the closing discs slide in vertical grooves. The closing discs (100, 102) are separated from one another by an annular spacer (120), the diameter of which is less than the diameter of the seating surfaces. The spacing ring is secured in position by raised portions on the inner side of the closing discs (100, 102) which engage from the inside in the spacer ring (120). The spacer ring guarantees the correct width of the gate (26) in accordance with the amount of wear. The difference in diameter between the valve seating surfaces (104) and the spacer ring (120) provides the gate with increased flexibility.

Patent ES-478308-A1 (ES)
Title: Apparatus for coordinating real time transfer of data from a processor to a magnetic media device
IPC: G06F3/08
Filed: 1979-03-05
Abstract: There is disclosed an improved interface apparatus and technique for real time transfer of characters from a text processor to a magnetic card recorder. Characters retrieved from a buffer are subject to reformatting and other operations, the duration of which varies within two character output cycles. The disclosed technique permits time, in effect, to be borrowed from succeeding character cycles. A character is processed and loaded temporarily in a register. The parallel character is then transferred to a serializer register which outputs serial bits to a card writer control for recording on a magnetic card. At the same time this transfer, serialization, and output is occurring the processor is preparing the next character to be written. A character can be output in real time so long as the interval between it and the preceding character is less than two character output cycles in length.

Patent ES-487285-A1 (ES)
Title: Holloware for uphill teeming
IPC: B22D7/06
Filed: 1979-12-27
Abstract: The invention relates to the units of a pouring system for uphill teeming. Conventionally, such units are formed by a pouring trumpet having a two-part heavy duty iron casing, and by runners set in channels in a heavy cast iron base plate, requiring skillful assembly on site. When unskilled personnel are utilized there is frequently incorrect assembly and positioning, leading to jointing and cracking, faults which in turn leads to molten metal penetration during pouring with consequent damage to the cast iron casing of the trumpet and the case iron base plate with the inherent danger of a complete break-out. The objective of the invention is to alleviate the problems outlined above, that objective being met by providing the units of a pouring system for uphill teeming each comprising an outer casing, an inner refractory liner and a refractory insulating material between the outer casing and the inner liner, each unit being pre-assembled as a complete unit for delivery to a casting bay. Considerable further advantages are realized when the outer casing is of a destructible material such as a cardboard tube.

Title: Apparatus for measuring the travel speed of automatic welding machines
IPC: B23K9/12
Filed: 1981-05-29
Abstract: A method and apparatus for controlling the travel speed of automatic welding machines uses a rotatable member which is engaged with the workpiece as the workpiece is moved relative to the welding head. The rotatable member advantageously includes one or more apertures on one side of which light is directed and the opposite side of which light pulses are received during rotation of the member and these pulses are used as an indication of the speed of the welding machine. In the preferred apparatus a separate frictional member is frictionally engaged with the workpiece and moved by the movement of the workpiece relative to the welding head and through suitable gearing drives the rotatable member having the aperture. Light is transmitted to one side of the rotatable member preferably from a light source through optical fibers and is picked up on the opposite side by similar optical fiber elements which transmit the pulse signals to a sensor for the purpose of giving a digital or other reading in respect to the speed involved.

Title: Flexible band-type printing head.
IPC: B41K3/06
Filed: 1981-09-05
Abstract: This invention relates to a belt printing mechanism with parallel mounted endless type belts which carry on their exterior surface print types. These type belts extend around an adjustment wheel and a plurality of star wheels where the star wheels are rotatable about a shaft where each star wheel has four corners. A catch mechanism is held under tension against the star wheels and holds these in predetermined detent positions to prevent free rotation of the star wheels. When printing multi-character symbols, the selected print types of adjacent type belts must be brought into predetermined printing positions. In order to assure a clean print copy, care must be taken that the print types rest in the exact same line height. In order to accomplish this, the catch mechanism for each star wheel is provided with a spring tongue which touches at least two separated points of the perimeter of its associated star wheel between two adjacent corners thereof. The plane of each spring tongue with respect to the plane in which its associated star wheel rotates is an acute angle. When the type belts are adjusted, the catch mechanism generates pressures which are clearly recognizable by the operator and which simplify the procedure of bringing the print types into their predetermined printing positions.
