Abstract: ABSTRACT OF THE DISCLOSURE          A fast response fluid temperature sensor is disclosed which consists of a silicon temperature sensing semiconductor chip mounted on an extremely thin fin having a high surface area to mass ratio.  The fin and chip combination are mounted in a frame assembly, with the thermal conductivity of the frame assembly being high and the specific heat being low for maximum heat transfer from the fluid being sensed to the silicon chip. The chip and fin assembly are illustrated as being open to the free flow of fluid around the assembly, no insulating material being provided between the fluid media being sensed and the fin and chip assembly, and a protective cage is formed around the fin and chip assembly.  Suitable connection is made between one electrical terminal of the chip and the fin and between the other electrical terminal of the chip and the external circuitry, with various modified forms of such connections being illustrated.

Abstract: ABSTRACT OF THE DISCLOSURE When fabricating apparatus from angle iron or similar shaped material, it is frequently useful to cut the material in complex shapes.  In the past it has been necessary to make a first cut in one plane, rotate the material, and make a second cut holding the second portion of the material in the same plane as the first portion was in.  In accordance with the present invention-tion, two cutting devices are so interrelated that a single pattern which represents the development of the desired cut may be used to control both of the torches to produce a cut on both portions of the material without repositioning the material between cuts.  This is accomplished by moving one cutting device in a first plane including a first surface of the material to be cut and a second cutting device in a second plane in-cluding the second surface of the material to be cut.

Abstract: APPARATUS FOR CONTROLLING THE FLOW OF        INTRAVENOUS FLUID TO A PATIENT     Abstract of the Disclosure Apparatus is included in a system for controlling the flow of intravenous fluid from a source to a patient.          Such apparatus is manually adjustable to vary the rate of such fluid flow.  Desired rates of fluid flow may also be set in such system when the apparatus is included in the system.          The system then overrides any previous manual adjustment of such apparatus and adjusts the rate of fluid flow in accordance with any such setting.  When a desired rate of fluid flow has been preset into the system, the system then operates to adjust the rate of fluid flow on an instantaneous basis so that the desired rate of fluid flow is maintained.         The apparatus is removably disposed in the system for controlling the flow of fluid to the patient.  Even after the adjustment by the system of the rate of fluid flow in accordance with any setting, the apparatus may be removed from the system to provide a rate of fluid flow in accordance with the manual adjustment of the apparatus.         A plug member in the apparatus defines a passage communicating at a first position with an inlet line and, at a displaced position in a particular direction, with an outlet line.  A resilient member such as a diaphragm may be disposed in the particular direction in the passage and may be displaced in a transverse direction from the inlet and outlet lines.  A rod stretches the diaphragm in the transverse direction.  A button may envelope one of the inlet and outlet lines to cooperate with the diaphragm in limiting the rate of flow of fluid through the passage.  The button may have a notch cooperating with the diaphragm in facilitating the flow of fluid through the passage at the desired rate.  A knob may be adjustably threaded on the plug member to press the rod against the diaphragm with a force dependent upon the adjustments of the knob.  *                    *                     *

Abstract: ABSTRACT OF THE DISCLOSURE           In a ceilometric system, light pulses are emitted from a transmitter towards overhead clouds and reflected back down towards a receiver which generates a photo-detector sig-nal transmitted by a gate whose gating interval is shifted in time relative to the light-pulse emission instant to define successive range steps.  During each dwell at a particular gating interval and range step, the photodetector signal is integrated to develop an integral signal for that range step.  The integral signal for each range step is digitalized and stored in a digital storage circuit, ordered in correspondence to the sequence of the range steps.  A microprocessor searches for the largest one of the stored integral signals and derives a ceilometric indication in dependence thereon.

Abstract: ELECTRONIC POSTAGE METER HAVING IMPROVED   SECURITY AND FAULT TOLERANCE FEATURES                   ABSTRACT OF THE DISCLOSURE A microcomputerized postage meter that provides high degrees of security and fault tolerance.  The meter maintains data security under low power conditions by the use of functionally nonvolatile memory units.  Register and other data which must survive normal and abnormal losses of power to the meter electronics are stored in dual redundant battery augmented memories (hereinafter designated BAMs).  Upon detecting an error condition, the microcomputer writes an appropriate fault code to the BAMs.  A mechanism for dis-abling the meter includes dual redundant flip-flops which are set to a "faulted" state upon detection by the microcomputer of a failure condition.  These flip-flops are powered by the BAM batteries.  They cannot be reset except by physical access to the meter interior, which access is only available to authorized personnel at the factory.  The fault flip-flops are also set when the microcomputer fails to properly execute its own operating program.  Once the meter has been set to a "faulted" state, the fault flip-flops hold two signals, MPCLR and SYSCLR, true.  The BAM contents may still be read out independently of the microcomputer which is prevented from accessing the BAMs.  This is accomplished by allowing power necessary to read the BAMs to be supplied to the BAMs without supplying power to the microcomputer.  Moreover, even if the microcomputer is powered, MPCLR prevents it from executing instructions and SYSCLR isolates it.  The various register values and the fault code then allow a reconstruction of the proper register values.
