Abstract: Data processing apparatus is provided with a paging facility constrained in that the number of pages of any group of pages (defined by a specific bit pattern is a first subset of virtual address bits) in residence inthe direct access data store is limited to n. The address translation apparatus included comprises two table look-up mechanisms arranged to maintain a mapping of selected virtual to real address relationships of pages in residence, the first table look-up mechanism having c /  n addressable locations of n fields and the second table look-up mechanism having c single field addressable locations, when c is the maximum number of pages in residence, so that, for a filled direct access data store there is one field in each table look-up mechanism for each page in residence. Both table look-up mechanisms are addressed by the first subset of bits of a virtual address presented for translation and, in addition, the second table look-up mechanism is addressed in response to the operations of the first table look-up mechanism. Either the first or the second table look-up mechanism generates, the real page addresses appropriate to the current mapping. The first table look-up mechanism contains entries each identifying the states of a second subset of virtual address bits of pages of the associated group in residence. The second subset bits of a virtual address presented for translation are compared with all the output fields of the first table look-up mechanism using n compare circuits, outputting to the second table look-up addressing mechanism. The remaining page address bit positions of the presented virtual address are compared with the output of the second table look-up mechanism, the fields of the second table look-up mechanism containing such remaining virtual address bits appropriate to the pages in residence. If either comparator fails to detect an equality a miss is registered and the second table look-up mechanism is only exercised in relation to potential hits.

Abstract: The light contains an incandescent lamp (2) which can be connected to a carrier (30), contacts of the incandescent lamp (2) being connectable to contacts of the carrier (30). The incandescent lamp (2) is directly or indirectly connected to a mating piece (10) which bears mating surfaces (12, 14, 50, 61, 62). The carrier (30) contains mating surfaces (32, 34, 56, 61, 62) which are assigned to the said mating surfaces of the mating piece (10) and correspondingly constructed. Owing to the said mating surfaces of mating piece (10) and carrier (30), it is ensured that only an incandescent lamp (2) having specific electrical or photometric values can be plugged onto the carrier (30). The incandescent lamp (2), the mating piece (10) and a transparent covering cap (6) as well as light-controlling means are preferably combined in a single structural unit, which owing to the mating surfaces can be plugged only onto a very specific carrier and in a defined alignment. <IMAGE>

Abstract: In a numerical-controlled machine tool a controlled object (e.g. tool TL1) is positioned in dependence upon a command value as modified by a tool compensation value. 
     A command value is held in a register CR and a compensation value is held in a register CPR. The command and compensation values are algebraically added by an arithmetic circuit ART2 and the result is used to position the tool TL1. The number of times the tool is used is counted in a counter UT and when that number equals a preset count value n1 held in register CTR (coincident unit CIN detects equality), a correction amount (ΔT1) is added to the content of register CPR by arithmetic unit ART3, to provide a new compensation value in register CPR taking into account tool wear.

Abstract: In ambient-air heat absorbers composed of many heat exchanger elements arranged one above another, the flowing air often flows too smoothly through the intermediate spaces, so that the heat exchange takes place only incompletely. As a result of the insertion of lattice grids onto the (smooth) surface of the heat exchanger elements, this uniform flow is varied. The result of this is a greater absorption of heat by the absorber.

Abstract: Apparatus is described for scanning a scene in bands of lines and reconstructing the scene in visible light. Use is made of a prism 1 in which the mirrors 3 make a sequence of various tilt angles with the axis of rotation 2. According to the invention all but one of the mirrors are used for scanning and reconstruction. To achieve this the angular spacing between the scanning and reconstruction locations (S,, R) around the prism is an integral multiple of the angular spacing between adjacent mirrors, which multiple is not a sub-multiple of the total number of mirrors. For all but one of the mirrors, the tilt angle of a mirror at a scanning location differs from the tilt angle of the mirror simultaneously present at a reconstruction location by the same amount and in the same direction.
