Abstract: PATIENT MONITOR FOR PROVIDING RESPIRATION AND ELECTROCARDIOGRAM                             SIGNALS                ABSTRACT OF THE DISCLOSURE          The patient monitor includes a patient unit having a probe connected to receive a carrier signal, which probe is adapted for connection to the body of a patient to be monitored.  The carrier signal is passed through the patient's body and modulated in accordance with the respirations of the patient to produce a modulated carrier signal.  A carrier detection circuit is connected to receive the modulated carrier signal and produce a demodulated respiration signal.  An ECG circuit also receives the carrier signal and filters out ECG signals.  The respiration and ECG signals are passed to an analysis unit.  Both the patient unit and analysis unit contain baseline correction circuits for maintaining a predetermined baseline.

Abstract: PHRASE PROGRAMMABLE DIGITAL                      SPEECH SYSTEM            ABSTRACT:      A digital  speech  processor  (200)  operates  in parallel with a programmable digital computer (102) to generate sequences of variable-length speech phrases and pauses at the request of the computer.  A speech memory (214)  within the speech processor contains digitally-encoded speech data segments of varying length.   A separate command memory region  (in 214)  accessible to and loadable by the computer, can be loaded with a plurality of commands.   When sequentially executed by the speech processor, these commands cause the processor to generate an arbitrary sequence of spoken phrases and pauses without  intervention by the computer.   Each two-byte command causes the speech processor to retrieve from the speech memory a particular speech data segment and convert it into speech, or to pause for a time interval specified by a number within the command.  When the programmable digital computer is not operating the speech processor to synthesize spoken words, the speech and command memory regions are used as auxiliary random access memory to increase the size of the memory space of the computer.

Abstract: Abstract of the Disclosure A safety shoe having a toe protecting cap which is shaped to conform substantially to the tip of the shoe and is provided at its portion facing the sole of the shoe with an inwardly directed flanged rim.  This toe protecting cap flanged rim is inserted into a groove provided in the vertical end face of the one piece sole and is retained therein by attachment of the upper of the shoe, whereby the upper groove wall is set back with respect to the lower groove wall by at least the thickness of the toe protecting cap.  The shoe upper is attached to the lower groove wall.  The manufacture of the safety shoe is simplified and production cost savings are realized by providing a one piece sole having a groove therein, whereby at least one of the height and depth of the groove is slightly less than the corresponding thickness and length of the flanged rim of the toe protecting cap.  The flanged rim of the toe protecting cap is tightly inserted into the groove in the one piece sole until it bears against the front face of the upper groove wall so that the toe protecting cap is retained immovably in the groove.

Abstract: ABSTRACT OF THE DISCLOSURE The invention relates to a sealing or coupling device for two elements which are to be concentrically connected together with one element inserted into the other - for example, a container and lid, two pipes, or a pipe and sleeve.  The device comprises a clamp body for insertion into the radial space between the two elements.  At least one of the elements is bounded by a conical surface facing the space, which conical surface extends behind the clamp body in the direction of the joint.  The clamp body consists of elastic, pliable, non-compressible material, which before installation has a thickness greater than the maximum width of the space, in a radial direction, and which is located in the region of the conical surface.  Means are provided for preventing axial movement of the clamp body away from the conical surface, and the smallest distance between the conical and opposite surfaces is selected to be 0.1 to 0.5 times as great as the radial thickness of the clamp body.

Abstract: ABSTRACT         A self-contained portable single patient ventilator/resuscitator of the type which has a timed cycle of operation, hut which a patient can override in response to his physiological needs. The ventilator/ resuscitator has a power source in the form of a chemical oxygen generator (18 or 132), fluid operated delivery means associated with the oxygen source, and control means.          The delivery means includes pump means (28 or 122) asso-ciated with an ambient air filter (32 or 120), a two posi-tion valve shiftable between inspiratory and expiratory modes, an output tube (42 or 130) and a mask (10 or 110) and head harness (12 or 112). When the delivery means is in the inspiratory mode at least a portion of the oxygen output is delivered to the patient (14 or 114), and when the delivery means is in the epxiratory mode at least a portion of the oxygen output is delivered to an accumulator (54 or 124). The control means (24 or 186,188,190,192) will cause the valve means (22 or 128) to cycle between its inspiratory and expiratory positions in a timed cycle established by timing modules (88,89 or 188,190). The control means additionally includes pressure sensing devices (90,92 or 202) which are capable of causing the valve means to be shifted to an inspiratory mode when the patient initiates an inspiratory effort, and which are also capable of causing the valve means to be shifted to an expiratory mode when the pressure to the patient exceeds its set peak pressure.

Abstract: ABSTRACT OF THE DISCLOSURE         METHOD OF ATTENUATING SEA ICE FLEXURE NOISE DURING SEISMIC SURVEYS OF PERMAFROST REGIONS      INVOLVING A PRECURSOR AERIAL AND/OR      SATELLITE MAPPING STEP           The present invention indicates that in exploration of permafrost regions of the world for oil and gas accumulations, flexure noise can be attenuated by careful placement of the vibratory source vis-a-vis the receiver array during collection of the Vibroseis ? -type data.  If the explorationist adopts a survey strategy in which the vibratory source is separated from the receiver array by a pressure ridge or its equivalent over the ice formation of the region under survey, then - surpris-ingly - the seismic reflection signals can be easily collected and displayed.  Result:  continuity of events from onshore reflec-tors can be easily followed offshore through the transition zone into deeper sea ice regions.  He is aided in formulating his exploration strategy by the use of aerial and/or radar photo-graphs or LANDSAT unmanned satellite data for mapping the pressure ridges of the area under survey.
