Title: Automatic h-register clear for prevention of erroneous convolution in digital adaptive echo canceller
Inventor: SUYDERHOUD HENRI G
IPC: H04B3/23
Filed: 1976-10-04
Granted: 1979-10-30
Abstract: ABSTRACT           An automatic H-register clear system for the prevention of erroneous convolution in adaptive digital echo cancellers is disclosed.  Incoming signals from the H-register are accumulated and compared to a predetermined threshold value and when the value is exceeded, the H-register is cleared with the occurrence of the internal housekeeping cycle of the echo canceller. The clearing of the H-register allows a new impulse responsive model to be generated from new sampled data. In one embodiment using analog implementation, the accumulation takes place using a sequence of signal processing of digital-to-analog conversion, full wave rectification followed by integration of the signal. In another preferred embodiment using a counter detection system, each word is compared to a threshold and if this value is exceeded, a counter is indexed.  If the value of the count in the counter exceeds a predetermined number during the sampling interval, the H-register is cleared.  In this latter embodiment, either analog digital implementation can be used.

Abstract: A VACUUM-CONTROLLED, SHEET-MATERIAL     SEPARATOR AND FEEDER SYSTEM                  Abstract of the Disclosure A high speed, vacuum-controlled sheet-material separating and feeder system is disclosed which handles a wide range of mixed thicknesses and sizes of envelopes and sheets.  The vacuum feeding of this system reduces frictional wear on the feed and separating rollers.  The sheets are stacked at one end of the system, and are fed to a first of two vacuum-controlled separator mechanisms.  The first separator mechanism is adjusted for thicker sheets of the range.  Sheets leaving the first separator are then fed to the second of the two separator mechanisms.  The second separator is adjuster for thinner sheets of the range.  Sheets leaving the second separator are ejected one at a time, in seriatim, here they then can be fed to other sheet handling equipment for processing.

Abstract: ABSTRACT OF THE DISCLOSURE           A locking cover for the ends of an electric meter retaining ring comprising a housing for assembly over the ends. The housing has an internal bracket with aperatures aligned with a  side aperture in the housing and positioned to be aligned with apertures in the outturned ends of the retaining ring to receive a locking member.  The internal bracket retains the housing in position on the meter ring and prevents axial move-ment of the locking member and is so positioned that the outer end of the locking member when assenbled, is spaced at or inside of the outer surface of the housing wall.  A collar is assembled into the side aperture and extends outwardly therefrom.  The collar is provided with apertures to allow a seal to be assembled across the collar over the end of the locking member disposed therein so that the seal must be broken to remove the locking member, and will provide evidence of attempts to remove the locking cover.

Abstract: ABSTRACT OF THE DISCLOSURE           It is known to make speciality candles which have incorporated into the candle body, compounds which impart ascent, repel insects or act as deoderizers.  Such compounds lower the melting point of the candle wax and thus necessitates special storage and transportation requirements for such candles.  Furthermore the included compounds may be release over the entire candle surface shortening the useful shelf life of the product.      The present invention seeks to overcome this drawback in the prior art by providing a candle structure comprising: a) a body consisting essentially of candle wax; b) an elongated candlewick in said body; and c) a columnar body within said body in the vicinity of said candlewick and coextending therewith, said columnary body formed of a mixture of candle wax and at least one candle specializing additive.

Abstract: ABSTRACT OF THE DISCLOSURE      The reduction of powered substance by mill grinding in a slurry may utilize passivated iron balls. In the case of nuclear fuels containing primarily uranium material the neutral to acidic reaction of the slurry is countered by the use of lithium hydroxide or ammonium hydroxide, by means of which the condition of the balls appears stabilized, at least on a batch basis, and contamination of the ground product with iron may be effectively controlled. In addition, the viscosity of the slurry is significantly reduced using ammonium hydroxide as the pH correction factor.

Abstract: ABSTRACT         A system for producing a velocity pattern for a vehicle such as an elevator car which must be brought smoothly to a stop accurately aligned with a desired one of a number of stations.   The distance between the vehicle and the station at which a stop is required (target distance) is expressed in digital form, and is processed electronically to produce a velocity pattern which results in constant deceleration of the vehicle during the entire approach except for an initial build-up to, and a final tapering off from, the constant deceleration.  A single adjustment for deceleration rate automatically adjusts the slowdown distance to the correct value to suit the selected deceleration rate.  The calculation is done repetitively at high speed to minimize any lag between the diminishing target distance and the corresponding velocity pattern.  Further adjustments permit control of the final tapering off from constant deceleration, with the slowdown distance automatically adjusted to suit these adjustments also.
