Title: Cylinder operated swinging ram cutoff  press
Inventor: BORZYM JOHN J
IPC: B26F1/40
Filed: 1980-10-10
Granted: 1982-11-09
Abstract: ABSTRACT OF THE DISCLOSURE A swinging ram type cutoff press for severing lengths of elongated stock such as tubing is disclosed of the type in which a ram is supported for swinging move-ment to operate a cutoff die set.  The disclosed cutoff press includes a power cylinder combined with a toggle link arrangement to produce the swinging movement of the ram. The relative geometry of the ram link support and the toggle mechanism coupled with the arrangement of the cylinder is such that a complete ram motion cycle is carried out during a single forward or return stroke of the cylinder.  The force exerted by the cylinder and toggle mechanism is not resisted either by return springs or the weight of the  ram, thereby further maximizing the usable power of the power cylinder.  Accordingly, one may reduce the cylinder size requirements for a given appli-cation.  In addition, the mechanical advantage afforded by the toggle mechanism provides for a maximum force at the ram full down position to maximize the force available for the blade stroke.  Cylinder size requirements are further reduced by an alternate form of toggle mechanism which compensates for the fact that the cylinder delivers less force on retraction than on extension of its output shaft.

Abstract: TITLE DIGITAL CONCENTRATOR FOR USE WITH A      DIGITAL TELEPHONE OFFICE ABSTRACT OF THE DISCLOSURE Signals from line circuits requesting service are transferred to a T1 channel via a Pulse Amplitude Modulated (PAM) bus.  The number of line circuits which can be served by a T1 line is not limited by the capacity of the T1 line since the probability of all line circuits requesting service at the same time is extremely low.  A processing unit detects requests for service and assigns them a slot in a memory which defines the scanning sequence for in-sertion of line circuit signal in the T1 channel.

Abstract: ABSTRACT OF THE DISCLOSURE          An improvement in the process for the production of aqueous, alkaline suspensions of finely divided low grit, crystalline, zeolitic sodium aluminosilicate by continuously mixing an aqueous sodium aluminate solution with an aqueous sodium silicate solution in the presence of excess sodium hydroxide solution at elevated tempera-tures and subsequently crystallizing the aqueous alkaline suspension of X-ray amorphous sodium aluminosilicate, so produced, at an elevated temperature, the improvement consisting of conducting said first mixing step at a temperature not to exceed 50° C, introducing finely-dispersed steam into said aqueous, alkaline suspension of X-ray amorphous sodium aluminosilicate for a period of at least 15 minutes while stirring, to heat said suspen-sion to a temperature of from 85° to 95°C, and crystal-lizing at this temperature for a period of 20 to 60 minutes while stirring with multistage agitators at a circumferential agitator speed of from 5 to 10 meters per second.  When following the above procedures, a finely-divided crystalline zeolytic sodium aluminosilicate is obtained with an extremely low grit content of 0.05% or less by weight.                   -A-

Abstract: A b s t r a c t A contact lever (1) has at one end a contact zone (3) for a stationary contact element (4) and is mounted at its other end on a pin (12) which upon tripping of the switch can move along a path (16) transversely of the contact lever (1).   In a zone between the pin (12) and a stop for the contact lever (1), such stop being formed by a casing part (9), a compression spring (13) acts on the contact lever (1) to produce the contact pressure and to move the pin (12) upon tripping.   The stop (9) has two projections or the like (14, 15) which extend towards the contact lever (1), one projection (14) being further from the pin (12) and nearer the lever (1) than the other projection (15).    Consequently, at tripping the contact lever (1) pivots first around the projection (14) further from the moving pin (12), then around the projection (15) nearer the pin (12), with the result that, purely as a result of the shaping of the stop (9), a substantial contact-opening force is produced at the start of tripping and a long contact spacing is left at the end of the pivoting movement of the contact lever (1).

Abstract: ABSTRACT OF THE DISCLOSURE Air bubbles in a transparent intravenous solution conduit are detected, regardless of whether the solution is opaque or clear, by directing a light source at the conduit and detecting light shining through the solution with a first light sensor while detecting light reflected from the interior wall of the conduit with a second light sensor.  If liquid is present in the conduit, whether clear or opaque, one sensor will see a low light level while the other sees a high level.  If air is present, both sensors see a high light level.  By EXCLUSIVE-OR'ing the outputs of the two sensors, a logic signal is obtained which is high only when the presence of liquid in the conduit is being detected.  Means using two sensor assemblies spaced axially along the conduit, and a counter associated with each, are also provided to allow passage of minor air bubbles, and to provide a backup signal representative of a predetermined volume of air passing either assembly independently of the other.

Abstract: HEART RATE DETECTOR                      Abstract A heart rate detector apparatus, particularly for use in an implantable defibrillator, is disclosed. The heart rate detector apparatus includes two distinct detector circuits each responsive to ECG waveforms of different characteristics.  One of the detector circuits is responsive to ECG waves having slew rates above a predetermined threshold.  The other detector circuit is responsive to ECG waves having lower slew rates, such as ECG waves of more sinusoidal shape.  A coupling circuit automatically couples one of the two detector circuits to an output circuit, such as a heart rate comparator.  In a specific embodiment, the heart rate comparator determines the heart rate, compares the heart rate with a predetermined rate, and, if the heart rate exceeds the predetermined rate for a predetermined time period, provides an output signal.  The output signal may be used to enable a defibrillating circuit to deliver a defibrillating shock to the patient.
