Abstract: Title of the Invention COMPUTER TO COMPUTER COMMUNICATION SYSTEM          Abstract of the Disclosure A computer to computer data communication system for minimizing software protocol is disclosed wherein transmitted errors in data transmitted from one computer to another are detected when they occur by means of a bit-by-bit data echo transmission technique.  True and inverted or complementary data are transmitted simultaneously serially over twisted pair lines for comparison, bit-by-bit by comparing each transmitted bit to the corresponding inverted bit to derive an error signal indicative of the condition of like polarity of the compared bits.  If the compared bits are of like polarity, an error signal is generated to enable correction of the transmission error on a word by word basis, while inhibiting processing of the uncorrected data.  Concurrently, received data is returned to the transmitting processor over a return data line for a like comparison.  When an error condition exists, the returned data is inverted, forcing an error condition and inhibiting further transmission for the remainder of the transfer cycle.          Thus, bit-by-bit detection, word-by-word correction and a variable block length capability in a double data transfer environment are accomplished, with both data processing and transmission inhibited until data errors are corrected.

Abstract: ABSTRACT OF THE DISCLOSURE         This specification discloses improvement in a mechanism for transferring the image on an image-bearing member onto a continuous transfer medium by bringing said transfer medium into contact with the image on the image-bearing member.  The mechanism of the prior art has been provided with tractors disposed before and behind the image transfer section for conveying the continuous transfer medium.  However, the drive timing between these two tractors has been extremely difficult to provide and the drive control mechanism has been very complex.  In addition to the drive control, the control for the starting of image transfer has been required and these control systems have been very cumbersome.  The invention simplifies the image transfer mechanism by using conveyor capable of conveying the transfer medium by slidably holding the same, and ensures stable conveyance of the transfer medium.

Abstract: ABSTRACT OF THE DISCLOSURE     Material for the production of hydraulic cements or for pozzolanic materials which develop cementatious character-istics after blending with an activator, is treated in a generally conical zone of a plasma reactor in which at least one plasma gun orbits about a vertical axis and is directed obliquely to said axis towards a counter electrode.  The material preferably includes at least a proportion of a naturally occurring carbonaceous material of low calorific  value, such as colliery spoil, oil shale or oil sand.  In such case, as the material emerges from the plasma it is preferably contacted with air to effect combustion of the combustible material.  The thermal energy thus released is recovered by suitable instru-mentalities and is preferably converted to electrical energy to power the plasma reactor.

A dispenser for flexible sheet material having a reserve roll that automatically moves into the dispensing position when the dispensing roll is almost exhausted. The sides of the reserve roll guide tracks are angled inwardly to engage the reserve roll spool at an off center point, so the spool is motivated to move downwardly toward the dispensing position whenever it is rotated. The leading edge of the reserve roll towel engages the remaining portion of the almost exhausted dispensing roll and is moved therewith to be threaded through the dispensing mechanism.

Abstract: 428D-101 Can.     Abstract of the Disclosure The present invention discloses a method for determining the overall efficiency of an automotive exhaust system including a catalytic converter for removing unburned hydrocarbons and car-bon monoxide from the exhaust gases.  The carbon monoxide, hydro-carbon, and oxygen levels are monitored in the exhaust gases at the tailpipe.  In a properly tuned engine, the base oxygen level is ascertained in order to establish the dilution effect of the air injection system on the exhaust gases which dictates the pro-per working curve on a disclosed Conversion Efficiency v. Carbon Monoxide at Tailpipe graph to be used in the procedure.  A source of extra hydrocarbon is injected into the carburetor air intake to enrich the fuel mixture to the engine without affecting the basic carburetor settings.  The engine and converter are thus overfueled thereby oxygen starving the converter to minimize any catalytic action.  The carbon monoxide level is then read.  The dilution factor corrected efficiency of the converter is then read from the graph as established by the working curve employed in light of the carbon monoxide level ascertained.  In addition, methods are disclosed for testing the air injection system and the carburetor side to side balance to establish the proper work-ing of the engine components before attempting the efficiency test procedure.

Abstract: ABSTRACT: "Hair-trimming apparatus."     A hair-trimming apparatus suitable for thin-ning hair comprises comb-like stationary and drivable cutting elements which cooperate with one another in such a manner that in all positions of the drivable element a space exists between every two adjacent pairs of cooperating teeth (6 and 7) of the two cutting ele-ments so that the teeth can penetrate the user's hair. The cutting edges of the teeth of at least one of the cutting elements are formed by re-entrant portions (21) of the side edges of the teeth so that only some of the hairs which enter the spaces between adjacent pairs of cooperating teeth are cut. The drivable cutting element preferably reciprocates in a direction parallel to that in which the teeth project from the cutting elements, but it can have other modes of movement, for example, rotary.

Both of the torque blades have tubular inner ends of D-shaped cross section with one extending axially a major part of a crank hub D-shaped cross section axial opening and telescoping the other within the crank hub.          Outer enlarged tubular ends of the torque blades are telescoped by ends of lock plugs of the respective locks and have partially circumferentially extending slots formed therein receiving radial tongues of washer-like members positioned circumferentially over the lock plug ends.  Thus, the torque blade inner connected to the crank hub and outer ends thereof are lost motion drive connected to the locks.  If a single lock is used with an inside hand operator, a single torque blade may have lost motion connection to the lock, extend completely through the crank hub and be received in the inside hand operator in direct rotative drive therebetween.

Binder liquid is fed on to the raised central portion and in operation the central plough keeps the raised central portion substantially clear of build-up of the material to be pelletized, so reducing formation of lumps and stabilizing operation.   Further ploughs or scrapers are disposed over the annular portion to maintain a constant level of build-up-of material thereon, at substantially the same depth as the height of the raised central portion.
