Abstract: AUDIO-VISUAL TEACHING SYSTEM AND METHOD                 ABSTRACT OF THE DISCLOSURE           A system for selectively supplying information including video information to operators, such as students, at plural stations, the information requiring responses, or answers, and the correct-ness of each operator's answer being displayed.  A television monitor is provided at each station to display video picture information.  In reply to a question, which may be displayed or audibly reproduced, a responding device is selectively operated by the operator.  The video picture information displayed at each television monitor is stored in a main storage device in the form of video picture signals representing predetermined still video information.  Selected ones of the video picture signals are supplied from the main storage device as a function of each response, or answer, by the operators.  A buffer store having a plurality of video picture signals storage channels correspond-ing to the number of stations is coupled to the main storage device to receive the selected video picture signals and to transmit these received signals to particular ones of the stations.  A control unit is coupled to the main storage device and to the buffer store for controlling the transmission of selected video picture signals from the main storage device to a particular video picture signal storage channel and for controlling the transmission of video picture signals from the storage channels in the buffer store to selected ones of the stations.         In one embodiment, a video display of the correctness of the operator's answer is provided.  It is one feature of this system to transmit new video information to each monitor in accord-ance with the pace, or progress, of each operator.     -i-

Abstract: ABSTRACT OF THE DISCLOSURE   The invention provides all improved apparatus for the detection of polar vapours in a gas which avoids the need for liquid reagents and requires little maintenance.  In its simplest form the apparatus comprises a body member defining a passage through which a gas stream may be caused to pass; an ionising source for ionising the gas stream;  and a collector electrode positioned in the passage downstream of the ionising source for collecting ions carried by the gas stream.  Improved performance can be obtained by the provision of means for selectively removing uncombined gas ions from the gas stream between the ionising source and the collector electrode whilst permitting ion clusters formed on polar molecules to remain therein.

Abstract: MOTOR GRADER BLADE MOUNTING AND TILT MECHANISM             A B S T R A C T      A motor grader has a circle with integral, depending arms at the rear, and the lower ends of the arms extend for-wardly so that blade carrying means, comprising bearing housings pivoted at their lower ends to the extremities of the arms, extends upwardly in very close proximity to the fronts of the arms.  Two hydraulic cylinder and piston units for tilting the blade carrying means are carried in sleeves which are integral with and between the arms, directly be-hind the upper end portions of the blade carrying means, which permits the use of very short stroke pistons that are well protected from damage by earth and rocks piled up by the blade.  In addition the units are mounted in spherical bearing and socket means for limited universal movement within the sleeves.  Further, the piston rods extend along shallow chords of a circle struck about the pivots which mount the bearing housings, so working forces are applied substantially axially to the piston rods in all positions of the bearing housings.

Abstract: ABSTRACT OF THE DISCLOSURE           A biochemical process is provided for the manufacture of a proteinaceous product, useful as a soil additive or as a feed supplement from animal waste and sewage sludge from municipal waste.  The process comprises the aerobic microbial treatment of an aqueous suspension of animal waste and includes the introduction of oxygen into the process at a sufficient rate to obtain a maximum digestion rate and a maximum temperature of the aqueous suspension under treatment.  Suitable rates are provided by introducing air at a rate of from 0.01 to 0.3 volume air per minute per volume of aqueous suspension under treatment.  The suspension is also agitated thoroughly to ensure intimate mixing of the oxygen with the liquid, contributing to optimum thermophilic microbial activity.  Preferably the reaction is maintained under adiabatic or near-adiabatic conditions thereby ensuring that the microorganisms that are congene ic in the waste adapt to and remain active at the high treatment temperatures which are employed.  If necessary, any increase in pH during the fermentation can be neutralized by the addition of acid.  The high temperature also effects pasteurization of the treatment liquid, thereby sterilizing pathogens present therein so that the microorganism cultures can be readily harvested to produce proteinaceous soil additives or feed supplement.
