Inventor: DAVIS THOMAS A
IPC: C23F1/46
Filed: 1991-06-03
Abstract: A method for the recovery and recycling of sodium hydroxide from the waste solution of aluminum etching operations.

Title: Hydrostatic transmission unit particularly for industrial machines
Inventor: HURTH FRITZ CARL ANTON
IPC: F16H47/02
Filed: 1991-10-18
Abstract: The hydrostatic transmission unit comprises a variable-displacement hydrostatic pump (1) which drives a first hydrostatic motor (2) and a second hydrostatic motor (3), at least one of which has variable displacement. One of the hydrostatic motors (3) is connected, by means of a kinematic gear train (5,6,10,11), to an output shaft (7) which is operatively associated with motion transmission axles (9). The unit comprises a clutch (12) interposed on the kinematic train (5,6,10,11) for the connection of the variable-displacement motor (2) to the output shaft (7) and a brake (20) which is operatively associated with the variable-displacement motor (2).

Abstract: The hammer holder (11) is supported in the frame of the weapon such that it can rotate about a rotation shaft (12). The hammer (6) is supported in the frame such that it can pivot about a pivoting shaft (7). The hammer (6) has a striking surface (8). The hammer holder (11) has a blocking surface (13) which interacts with a latching surface (9) on the hammer (6). The position of the hammer holder (11) which is defined by the rotation shaft (12), the location of the impact surface (8) of the hammer (6), which is determined by the pivoting shaft (7) of the hammer (6), and the position of the rear end of the firing pin (5) are selected in such a manner that, when the hammer (6) is located in its uncocked position, in which the latching surface (9) rests on the blocking surface (13), the striking surface (8) of the hammer (6) is at a distance from the rear end of the firing pin (5). The hammer (6) thus does not rest on the firing pin (5) in the uncocked state so that, if, for example, the weapon is dropped, a shot cannot accidentally be fired. Since, furthermore, the hammer (6) in the uncocked position is already at a distance from the rear end of the firing pin, a shorter and smoother movement of the trigger (3) is required for firing, which enables more accurate impacts. As a result of the arrangement, the hammer (6) is automatically uncocked every time after firing.

Filed: 1991-09-11
Abstract: A method of maintaining and/or enhancing tissue or plasma levels of glutathione is provided. Treatment of a mammal with a supranormal amount of glutamine, or a glutamine equivalent, prevents the reduction in tissue glutathione levels associated with exposure of the mammal to a compound capable of oxidative injury to the tissue. Such compounds may be drugs such as chemotherapeutic agents. Administration of a supranormal amount of glutamine or a glutamine equivalent after exposure of a mammal to a compound capable of oxidative injury to the tissue can ameliorate or prevent injury. Treatment of a mammal with glutamine or a glutamine equivalent can also reduce or prevent starvation- or radiation-associated oxidative damage in the tissues.
