Abstract: PHASE LOCKED FREQUENCY SYNTHESIZER WITH SINGLE        INPUT WIDEBAND MODULATION SYSTEM                    ABSTRACT    A single input wideband modulation system for a phase locked loop is achieved by interposing the inverse analogue of the closed phase locked loop transfer function between the modulation source and the VCO modulation input.  A first branch of the interposed circuit directly passes high frequency signals from the modulation source to a summing device tied to an input of the VCO.  A second branch of the interposed circuit boosts low frequency signals and blocks high frequency signals received from the modulation source and passes such signals to the summing device where signals from the first and second branches are summed to permit wideband modulation of the VCO.  All the modulation processing is performed outside the phase locked loop.

Title: Pressurized check valve
Inventor: PIPER BRITTON F
IPC: F16K15/14
Filed: 1989-06-13
Granted: 1993-05-11
Abstract: Abstract of the Disclosure An improved pressurized fluid check valve is pro-vided which, when incorporated into a drill string powered by a rotary table of a drilling rig, prevents drainage of fluid from the stand pipe and rotary hose when the flow of fluid through the drill string is interrupted, such as during the attachment of another section of drill pipe to the drill string.  The improved pressurized fluid check valve comprises (a)  a tubular body member having a bore extensive therethrough between first and second end portions thereof, the bore having an enlarged medial portion forming a valve chamber; (b) a flow restricting assembly supported within the valve chamber of the tubular body member for selectively closing the valve chamber to fluid flow in a pressurized mode; and (c)  a loading valve supported in an access bore formed through the side wall of the body member so as to communicate with the valve chamber.    The loading valve permits an annular pressure cavity formed between the internal wall of the valve chamber and an elastomeric sleeve of the flow restric-ting assembly to be pressurized with a gas so that the elastomeric sleeve of the flow retention assembly is compressed to close the valve chamber until such time as the pressure of the fluid flowing through the drill string is sufficient to compress the gas in the annular pressure cavity and permit the elastomeric sleeve to be moved to a non-compressed condition so that the valve chamber is in the open mode.

Abstract: NHL-SH-03 Canada MACHINE FOR CUTTING DISPOSABLE CONTAINERS                       ABSTRACT OF THE DISCLOSURE A machine is capable of cutting into small pieces the thin wall material of a plurality of disposable containers such as plas-tic bottles or metal cans.  A cutting section includes a pair of parallel shafts mounted for rotation in opposite directions with a plurality of cutting wheels rotatably supported on each of the shafts.  Each cutting wheel is securely mounted to be spaced from axially adjacent cutting wheels on the shaft to closely receive one of the cutting wheels on the other shaft therebetween.  Each cutting wheel includes a plurality of cutting teeth respectively having a leading surface and a trailing surface which meet at an apex to form a straight edge which is parallel with the shaft.  The apex precedes the leading surface during rotation of each cutting wheel. The cutting wheels on one shaft are angularly displaced from adja-cent cutting wheels on the other shaft to cause general alignment of each cutting tooth of a cutting wheel on one shaft to extend be-tween preceding adjacent cutting teeth and following adjacent cut-ting teeth of the adjacent cutting wheels on the other shaft prior to any overlapping of the teeth thereof.  The general alignment prior to overlapping causes the thin wall material to be initially bent around the cutting teeth for proper support in order to cause the apex of each cutting tooth to initially produce a transverse cut of the thin wall material by the apex.  After the transverse cut, longitudinal cuts toward the forward edge of the thin wall material complete the formation of the small pieces.

Granted: 1994-11-15
Abstract: Simultaneous solder connections of multiple electrical terminals to respective electrical leads is achieved by conducting thermal energy from an actuable heater body to the multiple connection sites via the terminals themselves, the terminals being formed integrally with the heater body.  The terminals are scored, perforated, etc., to facilitate severance from the heater body after soldering.  The preferred heater body takes the form of a copper substrate having a skin depth surface layer of magnetically-permeable, high resistance alloy.          Alternating current of constant amplitude and high frequency is passed through the heater body and concentrated in the surface layer at temperatures below the Curie temperature of the alloy.  For higher temperatures the current is distributed through the lower resistance substrate to limit further heating. During the time interval required for the surface layer to reach its Curie temperature, the resistive power dissipation creates sufficient thermal energy to melt solder that is pre-deposited on the terminals and/or leads.

Abstract: The lift landing door frame arrangement contains horizontally adjustable lateral caulking or sealing elements arranged at uprights of the door frame and a vertically adjustable top caulking or sealing element associated with the topside of the door frame. To avoid retouching due to the caulking elements at the time of placement of the lift landing door frame arrangement and to avoid the formation of gaps in the door frame after placement, each lateral caulking element comprises a rectangular sheet metal panel of a length which exceeds the height of the door frame. Each lateral caulking element engages with and is fixed to the interior of the related upright. Each lateral caulking element is also guided for simultaneous vertical and horizontal adjustment at a guide plate carried by the related upright. The vertically adjustable top caulking element is constituted by a U-shaped sheet metal strap which is disposed astride the front parts of the door frame and is laterally guided thereat. This lift landing door frame arrangement is particularly suitable in cases in which the lift or elevator shaft does not include lateral masonry returns at the landing openings.

Abstract: The invention relates to a method and a device with which an FM or PM modulated signal can be detected from a carrier directly, without the disadvantages that the use of an analog or a digital phase lock will cause. The direct detection is realized so that the instantaneous frequency or phase of the input signal is measured by direct time interval measurement so that the time measurement resolution is increased by using a delay line. The detected result is already digital, whereby no separate analog-to-digital converter is required.

Abstract: A method for the acoustic surveying of the surface contours of the bottom of a body of water by means of a crossed fan beam echo sounding arrangement wherein, for the purpose of obtaining an accurate, unfalsified surface contour, the measured contours obtained by scanning the bottom of the body of water in a direction transverse to direction of the heading of the surveying ship are recalculated by means of a continuously checked and adapted correction value. The correction value is determined from deviations between a calibration contour and a test contour. The calibration contour is a longitudinal contour which is formed from measured contours lined up in the direction of the ship's heading and cover a strip on the bottom of the body of water extending perpendicularly below the path traversed by the surveying ship. The test contour is recorded in the same manner as the measured contour but with the echo sounder pivoted by 90 DEG  about the elevation axis of the ship, i.e. from the same strip of ground perpendicularly below the fore-to-aft axis of the ship with which the calibration contour is associated.
