Abstract: The present invention provides a method of effectively recovering a hydrocarbon halide and the use of a specific aprotic polar compound for said method. Thus, the present invention provides a method of recovering a hydrocarbon halide comprising absorbing the hydrocarbon halide into an aprotic polar compound which has a 5 or 6 membered ring and a nitrogen atom at an alpha-position of a carbonyl group. In the present method, the absorbed hydrocarbon halide can be easily recovered by usual methods. 
     The present invention also provides the use of an aprotic polar compound which has a 5 to 6 membered ring and a nitrogen atom at an alpha-position of a carbonyl group for recovering a hydrocarbon halide.

Abstract: A program control system for a PC (programmable controller) using a sequence program of a plurality of parallel processing programs. The system has a select function instruction (1) for selecting a program determined by the conditions in the sequence program out of the parallel processing programs (2, 3, 4). By providing the select function instruction that selects programs to be processed in parallel, it is made easy to prepare a sequence program without the need of using the jump instruction or the branch instruction. When the sequence program is compiled in an executable form, furthermore, the instructions to be processed in parallel can be easily discriminated owing to the select function instruction, and the longest program is selected out of the programs to be processed in parallel and divided to meet the practical execution time to eliminate idle time.

Abstract: In a spinning mill, the mass of a sliver is to be made uniform for the purpose of producing perfect rovings. 
<??>Uniformity is obtained by measuring the thickness of the sliver after it has been compacted to a specific volume in a nip between two rollers. One roller is arranged rigidly, whilst the other is resiliently in engagement with it. Deflections of the resiliently mounted roller are a measure of thickness deviations, and the deflections are picked up by a sensor (44) which controls devices for making the incident mass uniform. 
<??>Known devices for this purpose have a natural vibration behaviour which falsifies the measured values of the measuring rollers in particular operating states. The measuring device (10) according to the invention is so designed in terms of construction that its natural vibration behaviour is such that it supplies accurate measured values in any operating states. Furthermore, the measuring device (10) is easy to serve.

Abstract: A multi-stage sprocket assembly for a bicycle has a small sprocket (12), a large sprocket (13) disposed coaxially with the small sprocket and a shift assist projection (16, 18, 23, 24) provided to the large sprocket for assisting a shifting movement of a chain (3) from the small sprocket (12) to the large sprocket (13). The assembly includes a guide face (15', 17a', 17c') for guiding an outer side face of link plate of the chain. The guide face is formed in a side face of a second tooth (15a) of the large sprocket facing the small sprocket, the second tooth (15a) being forwardly adjacent, relative to a moving direction of the chain, a first tooth (15c) of the large sprocket which comes into engagement with a leading portion of the shifting chain (3). The shift assist projection (16) is so displaced toward the small sprocket that the projection comes into engagement with the shifting chain portion at a position forwardy distant from a position of the engagement between the leading end of the shifting chain portion (3) and the first tooth by a distance which is substantially an integer multiple of a disposing pitch of the large sprocket teeth (13). Also, the shift assist projection (16) has such a radial height as to prevent this projection from extending into a rotary drive-moving path of the chain as fully engaging the large sprocket for propelling the bicycle.

Abstract: The invention comprises an improvement in a cleaning apparatus particularly useful for filters. A mechanism drives a hood into position adjacent partitions. A sealing member is selectively actuated to seal off at least one such compartment for cleaning while the remainder of the filter remains in service. Sealing is accomplished by interaction between the hood and the partitions. The invention also relates to techniques for selectively bringing the hood into contact with the partitions, and a construction of the hood and a media support plate which allows flexibility to lift and scour the filter media using a gas to dislodge impurities, coupled with a liquid backwash involving drawing filtered water back through the media to carry away the impurities out of the filter.

Abstract: Case lock (2), to be fastened so as to rest on a door, having a lock bolt (11) actuable by a lock cylinder and having a lock case (4) which interacts with the bolt and is to be fastened to the door frame (3) and to which is attached suspended a blocking stirrup (5) which can be swung out from the door plane and which has a longitudinally extending blocking slot closed all-round, through which, in the extended position of the bolt (11), the head (11'') of the latter, provided with blocking indentations (11'), is to pass transversely and engage behind. To improve and complete a case lock (2) of the generic type mentioned in the introduction, to the effect that it is even simpler in constructional terms and can also be produced more easily, but is also substantially easier to operate, it is so designed that there is provided on the lock case (4), laterally next to the blocking stirrup (5) and underneath its pivot bearing (16) and the path of movement of the bolt head, a blocking slide (13) which is transversely adjustable relative to the blocking stirrup (5) and which, in the suspended position of the blocking stirrup (5), projects laterally into the blocking slot of the latter and thereby blocks the blocking stirrup against swinging out, but which can be disengaged from this blocking position by an actuating knob (12) attached to it on the outside. <IMAGE>
