摘要:
A rotary index table wherein a detent oscillating about the table axis of rotation is translated radially inwardly during indexing and retracted radially outwardly during the return stroke of the detent, both actions being accomplished through a positive acting toggle link arrangement. The positive detent engagement with the table during indexing prevents table overtravel, and a locking detent is utilized to produce final table orientation. The table also includes expansible chamber motor means axially translating the table into a frictional locking engagement with its base.

This document provides methods and materials related to determining whether or not a mammal is receiving a steroid treatment. For example, methods and materials involved in assessing a biological sample (e.g., a urine sample) from a mammal for the presence or absence of a steroid or a steroid metabolite to determine whether or not the mammal is complying with a steroid treatment (e.g., a corticosteroid treatment for an allergic disease or asthma) are provided.

A pry bar comprises a shank portion and an integral U-shaped prying hook portion that is free of defined flats and instead has a continuous cam surface extending all the way from the apex of the U-shaped portion along the outer leg to the tip end. The pry bar includes axially extending channels in opposed sides of the shank portion such that the shank portion defines a generally I-shaped cross section with wider top and bottom beam portions and a narrower intermediate beam portion.

A resealable closure device for use on metallic cans is disclosed. The closure device comprises a metallic end including a flanged opening therein and a molded rubber or plastic element which is molded in an "inverted umbrella" position and which is capable of being inverted upon itself to seal onto the end.

Electro-optic amplitude varying elements (AVEs) or electro-optic multi-function elements (MFEs) are integrated into signal channels of photonic integrated circuits (PICs) or at the output of such PICs to provide for various optical controlling and monitoring functions. In one case, such PIC signal channels may minimally include a laser source and a modulator (TxPIC) and in another case, may minimally include a photodetector to which channels, in either case, an AVE or an MFE may be added.

A user appliance incorporating the invention includes a non-volatile memory for storing (i) a series of queries regarding operating problems that may be encountered in operating the user appliance; and (ii) a series of instructions on how to overcome the operating problems. Switching devices are provided which enable the user to input “yes” or “no” responses to the queries. The appliance further includes a controller that is responsive to an input from the user to cause a broadcast of the queries and instructions via a voice synthesizer. The controller further enables the user to skip certain of the queries by actuation of a switching device to input a “no” response to the controller.
摘要:
Probe (1) to be used in a microcalorimeter for various types of heat measurements. The probe having a good thermal contact with thermodetectors (5,6) used in the calorimeter. The probe is designed as a substantially cylindrical hollow body has at least one outer surface (4, 11) which is in contact with the thermodetectors. The outer surface of the probe is provided with a helix groove (2) in which a tube (3) for supplying the continuous flows is arranged in good thermal contact with the probe. The cavity (10) of the body is used for the introduction of the ampoules (9).
