Abstract: Abstract of the Disclosure In a data processing system, a memory (32) consists of data words and associated error-correction codes that are independently accessible; it is possible simultaneously to read a data word and write its associated error-correction code.  This allows a memory-control circuit (30) immediately to store in the memory (32) a data word sent by a processor (10) while it is concurrently in the process of generating the error-correction code for that data word.  The result is that the memory-control circuit (30) can subsequently fetch the newly stored data word before storage of its associated error-correction code is complete.  This reduces delays involved in error-correction-code generation.  The data word includes not only non-redundant information but also parity bits that both the processor (10) and the memory-control circuit (30) employ to determine whether a data word is correct.  If the memory-control circuitry (30) determines that a word that it has forwarded to the processor (10) is incorrect, it immediately fetches the corresponding error-correction code and corrects the location in memory.  Then, when the processor (10) finds that the parity is incorrect in the data word, it repeats its request for the data word in question, which the memory-control circuit (30) has corrected in the memory (32).

Abstract: Abstract of the Disclosure An  improved  liquid  dispensing  apparatus having a micro-adjustment of the opening travel of a needle valve of the apparatus.  This micro-adjustment comprises  a  sleeve-stop  member  which  is  axially movable but non-rotatable in the body of the appa-ratus.   One end of the sleeve-stop member forms an end-stop to opening movement of the needle valve away from the valve seat.  Screw threads of a first pitch are formed on an external portion of the sleeve-stop member and internal screw threads of a second pitch different from the first pitch are formed on a portion of the apparatus body.  A generally tubular adjustment screw element is engaged with both the internal screw threads  of  the  body  bore  and  the  external  screw threads of the sleeve-stop member so that rotation of the adjustment screw element causes differential axial movement of the sleeve-stop member for fine adjustment of the maximum opening needle valve travel.

Abstract: ABSTRACT    Upon a support part (1) a seat support (3) and a backrest support (4) are connected with a lever (7) by means of pivot joints (5,8).  To the backrest end of the seat support (3), a linkage (15) is coupled which is connected at its outer end to a slider (20) and a backrest (21).  The linkage (15) causes the slider (20) to move downwards with the backrest (21) during the backward tilting of the chair.  In this manner, and in a simple and space saving way, and in particular without occupying the space underneath the seat support (3), the pullout effect can be eliminated during the transition from the normal position to the reclining position of the lever.  By the arrangement of a spring device (11), e.g. a gas spring, in the knee-zone of the chair, the blocking of the spring device (11) can be achieved.

Abstract: The present invention relates to a method of manufacturing a release paper characterized in that a mixture of polyolefin and a silicone release agent compatible therewith comprising a reaction product of polymethyl hydrogen siloxane, vinyl group-containing poly-dimethyl siloxane and at least one olefin or polyolefin having one or more double-bonds is extruded onto a substrate of paper, fabric, film etc; the laminate is heat treated to cause the release agent contained in the mixed layer of the laminate to bleed onto the surface of the mixed layer to be thus localized and the localized release agent is fixed by curing. The resultant release agent's compatibility with polyolefin, film forming and stretching properties are improved surprisingly, and since a high concentration of release agent is localized and fixed by curing on the surface of the release agent layer, a small amount of tha release agent sufficies to exhibit a remarkable release effect.

Abstract: ABSTRACT            There is described a microprocessor-based valve motor control system  which  provides  control,  predictive  control  and diagnostic functions for a motor operated valve.  A valve stem position sensor measures the stem position and a load sensor measures the load on the valve stem.            A microprocessor periodically tests the status of the motor operated valve, and turns off the valve's motor if certain predefined criteria for the valve stem position and the valve stem load are not satisfied.  The periodic testing by the microprocessor  includes  comparing the valve  stem position signal with a preselected open valve position when said valve is being opened; and comparing the valve stem load signal with a preselected maximum desirable stem opening load when the valve is being opened, and with a preselected maximum desirable stem closing load when the valve is being closed.            When the valve  is being opened,  the  system predicts the position of the valve stem at a predefined time in the future and turns off the motor if the predicted valve stem position is beyond a preselected open valve position.  When said valve is being closed, the system predicts the load on the valve stem at a predefined time in the future and turns off the motor  if  the predicted  load value  exceeds  a preselected maximum desirable stem closing load.            Motor  overload  protection  is  provided  by  periodically measuring the actual load on the motor; comparing the motor load signal with a preselected maximum motor load value when said valve is being either opened or closed; and turning off the  motor  if the  motor  load  comparison  does  not  meet predefined motor load criteria.

Abstract: VAPOUR RECOVERY NOZZLE                           ABSTRACT        A vapour recovery nozzle (10) is disclosed in which the main body (11) of the nozzle has the vapour passage (36) located above the fluid passage (16), so that the fluid valve (22) is separated from the top of the nozzle by the vapour passage.  Thus the valve may only be removed through the bottom of the nozzle by removing the trigger mechanism (73) and removing the vacuum tripping mechanism (81) which is also connected to the trigger mechanism.  Removal of the tripping mechanism is also made easily determinable by the use of a soft aluminum seal (123) over the top opening of the trigger mechanism.  The tripping mechanism is responsive to dis-placement of the vapour recovery shroud (30) to prevent dispensing fuel unless the nozzle is in the fill tank.
