Abstract: Abstract Within the housing of a reserve battery cell is included an anode and cathode collector and a quantity of electrolyte which, when applied to the anode and cathode collector, causes the battery to generate an electric current,  The electrolyte is separated from the region containing the anode and cathode collector by a first separator which will burst upon the application of sufficient pressure.  The housing further encloses a piston means located in contact with the electrolyte.  The piston is capable of traveling within the cell housing and is capable of applying sufficient pressure to the electrolyte to burst the separator upon the application of externally applied pressure to the piston.     Batteries of cells so defined are not subject to common electrolyte problems which are existent with the prior art method.

Title: Twist on disposable filter
Inventor: GROEZINGER JOHN J
IPC: B01D27/08
Filed: 1987-04-30
Granted: 1991-12-10
Abstract: Abstract of the Disclosure Twist on Disposable Filter Spin on disposable filters are useful in removing contaminates from the fluid of fluid systems. Preventing axial elongation of the filter due to fluid pressure therein requires the use of thicker elements, thereby increasing the manufacturing cost.  The subject twist on disposable filter includes a twist-lock connector device which captures a portion of a housing between cooperating members of the twist-lock connector device.  The area of imbalance caused by seal placement is greatly reduced by the twist-lock connector device, thereby minimizing the forces tending to cause axial elongation of the filter.  This permits the use of less expensive materials therein and simplifies the manufacturing procedure.

Title: Petroleum equipment tubular connection
Inventor: FAIREY COLIN B
IPC: E21B17/043
Filed: 1987-08-05
Granted: 1991-11-26
Abstract: ABSTRACT     An anaerobic sealant composition is employed to seal a pipe joint  between pin and box  members intended for use in petroleum drilling operations. The composition is applied to one or both of the members.   The members are then joined and the composition cured into a 801 id form which bonds to the  members and fills the space between them, The constituents of the composition can be  selectively varied to control its lubricity which also affects the make up torque. Additionally, the concentration of the sealant composition can be selectively varied to control the  break out torque of the joint to which it is applied, and preferably make the break out torque substantially greater than the make up torque. Excellent seals can be   obtained using lower grade pipe, and the pin and   box  members can be made up with the application   of lower  torque  to  the assembly without reducing the sealing capability of the connection.  The preferred   composition  also  serves as a rust and corrosion   inhibitor for the joint.
