Diagnostic capability added to digital events evaluator
Digital events evaluator reviews events preceding system malfunction and automatically prints out most probable cause of problem. Analysis is performed by comparing input data with nominal values stored in tables. Each table has associated system mask to restrict comparison to preselected critical parameters within a given system.

Predicting service life margins
Margins are developed for equipment susceptible to malfunction due to excessive time or operation cycles, and for identifying limited life equipment so monitoring and replacing is accomplished before hardware failure. Method applies to hardware where design service is established and where reasonable expected usage prediction is made.

Apollo Operations Handbook Lunar Module (LM 11 and Subsequent) Vol. 2 Operational Procedures
The Apollo Operations Handbook (AOH) is the primary means of documenting LM descriptions and procedures. The AOH is published in two separately bound volumes. This information is useful in support of program management, engineering, test, flight simulation, and real time flight support efforts. This volume contains crew operational procedures: normal, backup, abort, malfunction, and emergency. These procedures define the sequence of actions necessary for safe and efficient subsystem operation.

Experiment M412: Landmark contrast measurements
The objective was to measure the visual contrast of landmarks with the surroundings to determine the relative visibility of terrestrial landmarks from positions outside the atmosphere. Because of a malfunction of the photometer, no photometric data were obtained. A trial sighting run was performed in which a landmark on the western African coast was sighted, tracked through the nadir, and photographed. The telemetry record of the photograph was examined. Telemetry data were inconsistent with the known conditions of the landmark.

A suborbital abort guidance scheme for orbital returns to the launch site
A suborbital abort guidance scheme is presented for returning the orbiter vehicle to the launch site in the event of a booster malfunction. The guidance scheme described, referred to as FBGUID, represents a simple closed-form technique to the flyback abort problem. In addition to returning to the launch site, objectives of the formulation are to preclude excessive structural and heating loads. A demonstration of the feasibility of this abort guidance concept is included for a 150-second abort time.

Experimental system for the control of surgically induced infections, operating and maintenance instructions D203613-004
An experimental portable system used to control surgically induced infections is described. The system consists of a portable clean room comprised of a laminar flow filter system consistent with Federal standards; a helmet-shoulder pad assembly; a communication system; a helmet ventilation system; a transparent walled enclosure; and surgical gowns. Guidelines for the set up and operation of such equipment are given along with corrective steps to use in case of system malfunctions. Cleaning procedures, maintenance requirements, and disassembly and transfer particulars are included.

Cytotoxicity assay automation
The design and construction of a system to automatically test HLP antigens are described. Major efforts were made to test and evaluate the performance of such a system, and compare its performance with nonautomatic tissue typing techniques. The system is based on the fluorochromatic cytotoxicity assay. Results show the system will work but is subject to malfunctions after a few samplings, and poses problems in showing correctly the necessary readings.
