Filed: 1991-10-10
Granted: 1995-01-24
Abstract: A method and apparatus are disclosed for joining a plurality of tubular thermoplastic workpieces by causing the workpieces to be stacked with their internal surfaces axially aligned. High frequency vibrations are applied to the respective inner surfaces of the stacked workpieces, the motion of the vibrations being predominantly along the axial alignment of the workpieces. Responsive to the dissipation of the vibratory energy, thermoplastic material from the inner surfaces of the workpieces becomes molten and flows and, upon the cessation of the vibrations, the molten and flowed material rigidifies to cause the workpieces to be joined. The high frequency vibrations, most suitably, are provided by a horn adapted to be resonant as a half wavelength resonator at an ultrasonic frequency in the range between 16 and 25 kHz.

Granted: 2003-04-29
Abstract: A device far measuring a physical quantity includes a transducer and circuitry far exciting the transducer with an a.c. square wave. The excitation circuitry includes two amplifiers, a switch and a resistor network. The excitation circuitry provides a plus one gain when the switch is in one position and a minus one gain when the switch is in a second position. A similar circuit synchronously demodulates the transducer's output signal. Another similar circuit synchronously demodulates the transducer excitation signal and provides a reference voltage to an analog-to-digital converter (ADC). The ADC converts the demodulated transducer output signal into a binary word. Both demodulated signals are filtered before application to the ADC. An example of the device is a force-measuring device such as a weighing scale incorporating a strain gauge load cell.

Title: Barrier, in particular for damming a tidal waterway during storm tides
Inventor: KRUEGER HEINZ
IPC: E02B7/20
Filed: 1991-01-24
Granted: 1998-01-06
Abstract: The storm tide flood barriers of the prior art for damming tidal surges have the particular disadvantages of expensive construction, a modification of the river cross section, complex and expensive methods to keep them clear of sand and silt deposits, and difficult service and maintenance. It must also be possible to maintain a continuous ship channel at least 200 to 400 m wide with sufficient depth at average low water. The barrier proposed by the invention consists of gate elements or components (1a-1d) which move on inclined planes (22), characterized by the fact that in the rest position on the edge of the waterway, preferably on the shore, the gate elements of components can be inserted inside one another in telescope fashion. With suitable lengths of the foundations (2) forming the inclined planes (22), the gate elements (1a, 1d) which can be moved in tracks (23) independently of one another can be removed completely from the water and pushed together above the average high water level (44). The cross section of the gate elements (1a-1d) has a triangular shape, whereby the ocean-side supports the dam wall (11) and the inland side (12) primarily absorbs the bracing forces (Figures 1 and 2).

Abstract: Overall production line equipment and related methods of operations are utilized in producing many large concrete panels, in an initial horizontal position, during each day of many operational days, with these panels preferably being later installed vertically with other like panels to form a sound barrier alongside a vehicle way. Each concrete panel has its own integral pilasters at respective edges, in turn having respective tongue and groove edges; respective patterns and color accents on each side, with the pattern on the then top side being formed by using a rockable stamp subassembly, mounted on a cart; reinforcing throughout the panels, inclusive of the integral pilasters; lifting subassemblies; and anchoring subassemblies, adapted to be later mated with a receiving subassembly anchored in a concrete footing, located where the panel with other panels forms a sound barrier alongside vehicle ways. This production line equipment is extended longitudinally, utilizing tracks to support several electrically powered vehicles, respectively referred to as tarp roller cart, back rail cart, mesh cart, rebar cart, screed cart, color spreader cart, and stamp cart. Electrical power is distributed via a continuous electric T-track power supply system extending alongside the tracks. Each respective deck, supporting the bottom form assembly for a panel, is tiltable, upon being lifted off of a footing location, along the back rail side thereof, as the front rail side thereof is pivoted, while supported at another footing location. Each deck, along the longitudinal outside edges thereof, forms respective sections of the overall longitudinal tracks. Portions of the bottom form assembly are removably secured at a first pouring location on each deck, and then at a cleared strip location on each deck, except for inside back rails, which are completely removed from a deck before the tilting thereof, which is undertaken to position a concrete panel nearly upright, to be lifted clear of the deck and the form portions.

Title: Drilling short radius curvature well bores
Inventor: GRAY BENJAMIN C
IPC: E21B7/06
Filed: 1993-05-13
Granted: 1996-01-09
Abstract: A supplemental horizontal section is drilled from a lower end of an existing well bore by a drilling tool which provides a short radius of the order of 20 feet of a curved section interconnecting the vertical initial section and the horizontal section.   This enables the drilling to take place without  expensive  monitoring  equipment  since  the  distances involved are relatively small.   The drilling tool includes a mud motor to which is attached a drilling section including a drill bit at the outer end thereof.   The drilling section is connected to the mud motor by a knuckle  joint which allows pivotal  action  about  an  axis  at  right  angles  to  the longitudinal axis of the drill bit.  A counterbore of increased diameter is formed at the lower end of the existing well bore and the knuckle and drill bit located therein.  The knuckle is biased toward one side of t he counter bore by a leaf spring so that  the  longitudinal  axis  of  the  drill  bit  takes  up an inclined position with a knuckle bent at a shallow angle.  As the drill bit forms a supplemental bore to one side of the main bore the knuckle pivots to gradually increase the angle up to a maximum angle at which the drill bit cuts a curved path.  The diameter of the drill bit is selected so that the motor and drill bit section can pass through the curved section to the horizontal section.
