The foam or other insulative material has a pre-selected thickness which provides a sufficient R (thermal) value.  This insulative drainage system is formed into panels and then adhesively applied to the exterior of a foundation or other retaining wall using any suitable and well known adhesive.  Preferably, each panel is provided with interlocking joints which permit a watertight fit between adjacent panels.

Title: Pneumatic percussion hammer
Inventor: LISTER WILLIAM
IPC: E21B4/14
Filed: 1987-10-26
Granted: 1992-02-11
Abstract: ABSTRACT OF THE DISCLOSURE:           A pneumatic percussion hammer for rock drilling has a tubular casing (10) with a top sub (23) for connection to the outer tube of a double tube drill stem, an air feed pipe (19) from the top sub (3) extend-ing co-axially into the casing and co-axially about an air outflow pipe (21) for connection to the inner tube of the drill stem, its lower end being slidable in an air passage (38) through a bit (31) of which the shank (32) is slidable, a driver sub (33) at the lower casing and is topped by an anvil (35), this passage (43) having ducts (39) being to the exterior of the bit, the air outflow pipe having ducts (44) to the bottom of the bit (31).  A tubular piston (27) slidable in the casing (10) and about the air outflow pipe (21) slidably engages, when brought down onto the anvil (35), a sliding seal tube (37) rising from the air passage (38) through the bit, shank and anvil.  Annular chambers (11, 12, 13) are formed within the casing (10) and the axial passage of the piston is divided into upper and lower passages (29, 30).  The piston (27) is so formed with ports (45, 46, 47, 48) as to act as a valve for effecting reciprocating movement, impacting the anvil (35) on its downstrokes, but if the casing (10) is raised to lift the bit (31) from its work face, the anvil (35) and piston (27) so descend that the hammer is in a state of balance and automatically ceases operation.

Title: Probe coupled waveguide multiplexer
Inventor: ELLIOTT JOSEPH A
IPC: H01P1/213
Filed: 1987-11-02
Granted: 1990-12-18
Abstract: PROBE COUPLED WAVEGUIDE MULTIPLEXER                ABSTRACT OF THE DISCLOSURE        A probe coupled waveguide multiplexer (10) is provided including a first waveguide (12) which serves as a multiplexing manifold; a second waveguide (14), having a cavity (31), typically a filter, which is probe coupled to the first waveguide (12); and a third waveguide (20) which has a cavity and is probe coupled to the first waveguide such that the probe (17) of said third waveguide (20) is diametrically opposed to the probe (15) of said second waveguide (14) and the second and third waveguides (14, 20) are mounted in the same transverse plane in co-planar relation.  The probe coupling method and apparatus disclosed herein allows the waveguide filters (14, 20) to be mounted on the manifold (12) in a close physical relation thereby minimizing the length of the manifold and associated costs.

Title: Antibiotic zeolite
Inventor: NIIRA REIJI
IPC: A01N59/16
Filed: 1987-12-04
Granted: 1992-06-30
Abstract: ABSTRACT OF THE INVENTION    An antibiotic  zeolite and an antibiotic resin composition containing thereof are provided.  The antibiotic zeolite is prepared by replacing all or a part of ion-exchangealbe ions in zeolite with ammonium ions and antibiotic metal ions such as silver, copper, zinc, mercury, tin, lead, bismuth, cadmium, chromium and thallium.  The antibiotic resin composition comprises the antibiotic zeolite and a resin such as polyethylene, polypropylene, polyvinyl chloride and polystyrene.

Title: Insulating non-removable type concrete wall forming structure and device
Inventor: YOUNG DAVID A
IPC: E04B2/00
Filed: 1988-03-25
Granted: 1993-01-12
Abstract: ABSTRACT OF THE INVENTION    A synthetic plastic wall tie of variable lengths for use with concrete forms.  The tie has a pair of T-shaped end sections at its opposite ends.  Each of the T-shaped end sections including a stem having a sufficient thickness for receiving an end of a screw in threaded engagement therewith.   The T-shaped end sections have parallel cross pieces at opposite ends of the tie.  An intermediate wall tie section connects the T-shaped end sections together.  The intermediate wall tie section has a pair of round flange-like water-stops extending radially outwardly out of the intermediate wall tie section and are joined therewith in integral one-piece assembly therewith.  The water-stops serve to inhibit water flow axially of the wall tie and through a concrete wall structure where the tie is embedded.  The round flange-like water-stops further serve to provide means for locating reinforcing rods extending at right angles to the wall ties when the wall ties are mounted in a concrete form.

Title: Shower-partition
Inventor: BAUS HEINZ G
IPC: A47K3/36
Filed: 1988-03-30
Granted: 1992-03-17
Abstract: ABSTRACT OF THE DISCLOSURE:     A shower-partition comprising a wall-element consisting,  more particularly,  of an at least partly transparent material which is to be arranged against the wall of a room.   The object is to provide,  at a low structural cost, a stable attachment of the wall-element to the wall of the room, and the alignment of the wall-element in a simple manner.  In order to accomplish this, the wall-element is secured to the stationary wall of the room by means of a crosspiece which comprises a first support-surface for the wall-element and a second support-surface for the wall of the room.   The support-surfaces is preferably arranged at right angles to each other.

Abstract: ABSTRACT OF THE DISCLOSURE         Disclosed are reaction products of terpene compounds and 2,5-dimercapto-1,3,4-thiadiazole of the formula (II)                         (II) wherein R represents a pinene residue having the structural formula   or limonene residue having the structural formula   and R2  may be same as R or hydrogen, alkyl, hydroxyalkyl, alkylthio, phenylalkyl and alkylated phenylalkyl groups, some of which are novel.  The reaction products are useful as antiwear agents and antioxidants in lubricating compositions.
