Abstract: A method of and an apparatus for measuring the softening point of a vitreous specimen in which the viscosity variation as a temperature function is determined by applying torsion to the specimen and measuring the transmitted torque as a function of temperature.

Abstract: This invention is directed to compounds of the formula ##STR1## wherein X is a thiazine or thiazepine of the formula ##STR2## These compounds possess angiotensin converting enzyme inhibition activity and are thus useful as hypotensive agents.

Abstract: In a package sortation conveyor comprising an endless apron supported for movement on a frame defining a main line and one or more side outlets therefrom, and a plurality of pusher elements mounted for sliding movement on the apron from one side thereof to the other to push a package through one of the side outlets, each pusher element has a guide pin depending therefrom and an anti-friction bearing on the upper part of the guide pin for cooperation with a switching mechanism and a camming bar in such manner that when a pusher element is diverted from its rest position at one side of the apron, the bearing thereon will engage the camming bar during the balance of its travel across the apron. In addition, special guide members are provided for preventing any incompletely diverted pusher element from jamming against a stationary part of the conveyor and for preventing any pusher element from jamming against a package which has been held against forward movement on the apron.

Abstract: A laser materials treatment system in which the (1) laser head and delivery optics, (2) power supply, (3) cooling unit, (4) microprocessor and (5) keyboard and display units are each contained in a separate modular unit. The entire device can therefore be arranged in various ways to conform to particular spatial requirements.

Abstract: System for regulating temperature of hot water in a wall-hung instantaneous mixed gas heating unit, in which the value of the temperature detected by a sensor inserted on the output of the secondary circuit of the hot water exchanger is compared with a set value, and their difference or error value is sent to the input of an amplifier of proportional-integrational-derivative type (P.I.D.), whose output is connected to one input of a selector of minimum value or power, to the other input of which is sent the difference or error value between the temperature of the heating system water and the corresponding maximum tolerable set temperature. The output of the selector then commands the gas modulating valves through a power amplifier, as well as the gas on/off operating valve through comparison with a signal proportional to the minimum thermal power that can be supplied by the heating unit.

Abstract: A system for the alignment and assembly of optical fibers to photodetectors in a hermetic package with a glass window and without fiber tail. One end of an optical fiber is terminated with an optical fiber support member. A support plate is provided with two concentric seats on opposite faces of the plate. A photodetector is inserted into one of the seats, and the connector part is inserted into the other seat. Synthetic resins are used to secure the photodetector and connector part to their respective plate seats.
