Title: Killing valve for crude oil and natural gas production wells
Inventor: BIESTERFELD JOHANNES
IPC: E21B34/06
Filed: 1983-02-03
Abstract: The invention relates to a valve, which can be opened hydraulically and closes automatically, for circulating treatment fluid in the casing of eruptive crude oil or natural gas wells. According to the state of the art, the killing fluid is pumped "over the top" into the deposit or circulated in via valves which have to be opened mechanically. In many cases this is not possible, such as, for example, in the case of erupting pump wells with a built-in subsurface pump in the string. According to the invention, the technical problem is solved when, according to sheet 1 of the drawing, the killing valve consists essentially of a bevel seat valve (3) and (4), which is connected to the body (1) and is held closed by means of a helical compression spring (2). Internal excess pressure against (F1), opens the valve and, at the same time, starts to act on the surface (F2) which is many times larger, so that the valve (3) is lifted far from its seat (4) and damage due to restriction is avoided. In use, the killing valve is as a rule installed as a constituent part of the flow string, as deeply as possible in the well. <IMAGE>

Patent DE-3324882-A1 (DE)
Title: Press for converting wastes into new workpieces
IPC: B30B15/34
Filed: 1983-07-09
Abstract: The press in respect of which a patent is applied for contains toothed bars between which the stamp is pressed down. Retracting, movable teeth permit the stamp only to advance for pressing purposes; when it is stationary, they hook securely. If the stamp is divided into two halves, one half is advanced by means of excess pressure which is generated between the two halves, while the other half is retracted by means of air at subatmospheric pressure. This can be done by means of bellows or cylindrical vessels. Similarly with magnetic vibrators: the interior magnet is advanced, becomes securely hooked and draws the exterior magnet after it. A wheel with two beads is inserted between the halves of the stamp. When the wheel is turned, one bead first advances one half of the stamp, then the second bead engages on the second half and pulls it after the first. <IMAGE>

Title: Process for the preparation of phenol-aldehyde condensates, and their use as binders for foundary castings
Inventor: GALWAS GERHARD CHEM ING
IPC: C08G8/04
Filed: 1984-06-25
Abstract: The invention relates to a process for the preparation of a foundary binder by condensation of phenol and aldehyde in a molar ratio from 1:0.9 to 2.0 in the presence of divalent metal ions as catalyst. This process is characterised according to the invention in that the condensation is carried out in aqueous medium, in that the reaction mixture is rendered alkaline as soon as its content of free formaldehyde has dropped below 15 % by weight, and in that the condensation is terminated when the content of free formaldehyde in the reaction mixture has dropped to below 3 % by weight (the percentage data in each case being based on the reaction mixture). The process according to the invention gives a binder which combines the advantages of known phenol resols (for example relatively short curing times and relatively low curing temperatures) with those of known novolaks (for example a relatively long shelf life and a relatively high resistance of the foundary castings produced therewith). In addition, the binder allows a novel and advantageous use since it can be employed in aqueous solution and with aldehyde-liberating substances as a curing agent for the production of foundary castings.

Title: Welding goggles
Inventor: SASSI ELIO
IPC: G02C9/02
Filed: 1984-07-14
Abstract: Welding goggles, having a built-in welding visor which can be pivoted about an axis to open the viewing slit and is provided with a mounting for the insertion of spectacles, according to Patent Application No. P 3417214.9, characterised in that the protective glass, the welding visor and the corrective viewing glass are arranged in an insert, separate from the hood, in such a manner that this insert can be pushed into the frame and the lenses, resting in guides, can be easily interchanged. This frame can also easily be inserted into a protective helmet. The welding visor consists of two parts, of which one part is vertically or horizontally displaceable by remote control, exposing or masking the viewing slit. As a result of this displaceability, the possibility exists of keeping the overall length of the frame, and hence of the welding goggles, as short as possible. As a result of the fact that the welding visor is arranged in a frame provided with guides, the visor can very rapidly be exchanged for autogenous or electrical welding work. The frame, together with the lenses, is designed to receive a protective shield for electrical welding work, or the head protection. Combining the frame, together with lenses, with a protective helmet gives adequate protection for eyes and head.
