Title: Cast-in-place manhole liner apparatus and method
Inventor: TRIMBLE CARROLL O
IPC: E02D29/12
Filed: 1989-08-30
Granted: 1994-04-26
Abstract: ABSTRACT OF THE DISCLOSURE There are disclosed apparatus and methods for casting poured concrete liners in manholes or the like wherein a collection of sheet-metal, flanged, arcuate panels is provided which panels can be assembled in belts of gen-erally circular cross-section commencing from the bottom of the manhole to provide a complete form structure for casting a concrete liner with a mini-mum thickness of about three inches and including openings created by sectional cylindrical inserts, all of which can be assembled, then disassem-bled after the concrete liner has set.  An extensive variety of panels to accomodate different shapes of manholes includes panels for forming right conical belts, for forming offset conical belts, and for forming wedge-shaped belts to make transitions between vertical and tilted sections of the man-hole. A key-panel for these various belts is provided to prevent capture of the panels by the poured concrete liners which includes a relatively narrow portion with vertical flanges fixed at an angle to one another which angle diverges toward the center of the form structure.  The methods in-clude jacking the form structure after a part of the liner has been formed and poured to cause it to fit relative to the manhole and inlet pipes into the manhole, before pouring the remainder of the liner.

Abstract: OPTICAL DISTRIBUTION OF ANALOG AND DIGITAL SIGNALS USING OPTICAL MODULATORS WITH COMPLEMENTARY OUTPUTS                ABSTRACT OF THE DISCLOSURE A novel optical system is taught including an optical source, an optical modulator having at least one optical input port for receiving the optical signal from the optical source, a modulation port for receiving the optical signal from the optical source, a modulation port for receiving a modulating signal, and complementary output port signals.  The complementary modulated output signals are applied to one or more optical receivers at the other end of an optical transmission link.  In one embodiment, the two complementary signals are provided to two separate optical receivers, thereby allowing distribution of optically modulated signals, for example, in a cable television or other type distribution system.  In another embodiment, the two complementary modulated signals are applied to a single balanced receiver, thereby providing information content to the complementary receiver twice the power level available on either one channel alone.  Furthermore, utilizing a balanced receiver, common mode error signals cancel, thereby increasing the signal to noise ratio of the system.  In one embodiment of this invention, a single optical transmission channel is used, and the two optically modulated signals are separated in polarization so as to be capable of being separately detected on the receiving end of the link.  In one embodiment feedback means is used to insure proper polarization states for the two complementary signals.

Abstract: Contact  material  of  the  type  in  question,  in particular in biological water treatment,  must provide optimal support for the "biological lawn" required for this purpose and be uniformly wettable.  With known striplike contact material it was found that the strips become smooth under load and consequently provide poor support for the "biological lawn" and tend to stick together.  The novel contact material has at least one tension element attached to the strips.  This tension element takes the strain in the  suspended  state,  leaving  the  strips  essentially unstrained and retaining their profiling conferred upon them in the course of manufacture.

Abstract: A machine for vertical transportation of goods, for instance transportation of pieces of packages from a packing line (15) onto a pallet (17). In a preferred embodiment the machine comprises a vertically movable lifting device (2) provided on a horizontally travelling waggon (1), said device (2) being provided with lifting forks (16) for receiving and lowering the pieces of packages. Preferably counterweights (12) are provided on said travelling waggon (1), said counterweights (12) being connected to the lifting device (2) by wires (11). The counterweights (12) are heavier than the lifting device (2) but the weight thereof is less than the total weight of the lifting device (2) and the thereon loaded pieces of packages. The transmission comprises an endless loop (4) preferably a cogged belt, which at (9) is fixedly mounted to the lifting device (2), which is driven by one single small motor (3), preferably of the electrical type. During a cycle of operations the pieces of packages are fed from a packing line (15) out onto the lifting forks (16) of the machine until they abut a start impulse switch (5) that starts the motor (3). Due to the weight of pieces of packages the lifting forks (16) are lowered until they are stopped by the pallet (17). Then, the motor (3) pulls the travelling waggon (1) backwardly. However, the pieces of packages are stopped by support rolls (13) and will rest upon the pallet (17). In a rear position the motor (3) is reversed by a switch (6). Then, the lifting device (2) provided with the lifting forks (16) is drawn upwardly by the counterweights (12) until it reaches a mechanical stop (14). The motor (3) continues to be in operation and pulls the travelling waggon (1) forwardly until it reaches a terminal position switch (10) that stops the cycle of operations. Then the cycle of operations is repeated until the pallet has been loaded up to a desired level.

Abstract: The present invention relates to a method for comminuting a coarse lump mineral material in an autogenous primary grinding system, in which an ingoing material is divided into a coarse fraction and a fine fraction is determined by a crushing point determined by the point of intersection between two tangents drawn through two adjacent inflexion points on a size distribution graph obtained by screen analysis of a grinding mill charge of material obtained after an autogenous grinding process. The smallest particle size of the coarse fraction is greater than the particle sizes in the upper of said inflexion points, and the ratio between said fractions is determined on the basis of achieving a given charge quantity for a particular, selected set-point power value fo the mill in question, and determined with respect to a selected degree of grinding.The grinding efficiency of autogenous primary grinding mills is greatly improved by means of the invention (Figure 4).

Abstract: Described is a process for producing methane-rich, pipeline-quality gas from raw gas produced by gasifying carbonaceous materials. Following any needed adjustment of its H2/CO ratio, which can be by a preconditioning water gas shift reaction or its reverse, the raw gas is fed to a direct methanation reaction (2H2 + 2CO-><- CH4 + CO2) which does not require substantial addition of steam. If needed, the intermediate product gas from the direct methanation reaction can be passed over a water gas shift catalyst to control its H2/CO ratio so that after removal of acid gases its methane content can be raised further over a nickel catalyst. This enables production of a very high heating value pipeline gas with only one acid gas removal step in the entire process sequence. In the alternative, the intermediate product gas can be subjected to cryogenic methane separation, with the separated H2 and CO fed back to the direct methanation and the separated methane used as SLNG. A preliminary direct methanation step can be carried out prior to any needed preconditioning step.

Abstract: The invention relates to a circuit for recognising a reference frequency signal which is transmitted with a data signal in time- division multiplex mode. A circuit of this type is provided for mobile radio systems in order to correct the frequency standard of the mobile stations through transmission of a reference frequency from the (fixed) base stations. In order to ascertain the temporal position of a reference frequency signal of this type, a solution is to be described in the implementation of which expensive circuits and high processing speeds are avoided. The invention provides a circuit with two transverse filters (1) which serve to distinguish between the data signal and the FC burst (frequency correction burst). They are designed so that the transmission factor of one filter shows a minimum at the FC frequency, while that of the other shows a maximum at that frequency. A device (2, 3) to determine the absolute value of the filter output signals, an arrangement (4 to 9) to form the sliding mean value over the period of a burst length and a device (10) to form the quotient of the output voltages of both paths are in each case connected downstream from the transverse filters (1). <IMAGE>
