Title: Apparatus and process for forming uniform, pelletizable sludge product
Inventor: DAUSMAN JEROME
IPC: C02F11/13
Filed: 1989-06-09
Granted: 1994-09-20
Abstract: Abstract An automated, non-polluting process and apparatus for mechanically dewatering and heat drying liquid sewage sludge of widely varying solids content to form a pelletizable, dried sludge of predetermined uniform solids  content without  requiring  recycling of previously heat processed sludge.   Prior to being dried,  the sludge is mixed with flocculation and coagulation promoting chemicals and is dewatered in a belt-type press.  Drying takes place within an indirect heat dryer including an enclosed housing for capturing all gases and particles entrained in the gas driven off during the drying process.   The gases and particles are advanced by means of a fan first through a cyclone separator for removing dust particles and next through a water jet scrubber prior to being exhausted or burned in order to control odor.  The dust removed by the cyclone separator is recombined with the output from the indirect dryer prior to being pelletized.   An automated start-up and shut-down control circuit is disclosed for producing the maximum  degree  of automation of the overall system and process.

Abstract: ABSTRACT     A vehicle cellular telephone is mounted on the side of a vehicle sun visor which is in clear view of a driver when the visor is in the downward shading position.  The telephone has a memory for storing selected telephone numbers in accordance with numbers pro-assigned by a user and a dual system of controls for placing outside telephone calls.  The dual controls for placing outside calls comprise a first linear array arranged across the lower edge portion of the telephone for "speed dialing" outgoing calls corresponding to the numbers stored by the user in the memory and a second square array of controls for the regular placement of outgoing calls.  To "speed dial" an outgoing call, the pre-assigned number which corresponds to the telephone number of the outgoing call stored in the memory is entered into the linear array.  To place an outgoing call in the regular manner the telephone number of the outgoing call is entered into the second array.  There is also provided a linear array of operating controls above the first linear array and an alphanumeric display for displaying massages and the telephone numbers of outgoing calls.

Abstract: DIGITAL VIDEO ENCODER     Abstract A differential pulse code arrangement reduces the bit rate of a composite color video signal by sampling the video signal at a predetermined rate of m times the color sub-carrier frequency, predicting the present video signal sample from reconstructed past samples and forming signal representative of the prediction error in a first predictive loop. The bit rate is further reduced in a second predictive loop embedded in the first predictive loop by generating a signal predictive of the error signal and forming a signal corresponding to the difference between the error signal and the signal predictive thereof. The difference signal is quantized and encoded for transmission. The error signal is reconstructed by summing the quantized difference signal and the predicted error signal and the prediction of the error signal is formed responsive to the sequence of past reconstructed error signals. The m-lth video signal sample is then reconstructedby summing the reconstructed error signal and the signal predictive of the m-lthvideo sample and a signal predictive of the next occurring video sample is generated responsive to the sequence of past reconstructed video samples.

Abstract: A cellular radio system in which the mobile radio stations in the zone of any base radio station assign themselves to the control channels allocated to that base station so as to evenly spread the volume of traffic over such control channels. The base station transmits on each control channel a channel group code signifying the range of group code numbers allocated to that particular control channel. Each mobile station stores its identifying group code number, scans the group code numbers of all control channels, and assigns itself to the control channel having a channel group code which includes its group code number. The spread of traffic over the various control channels can be changed by the base radio station simply by changing the channel group codes of the various control channels, without addressing specific commands to the mobile radio station.
