Abstract: 1459827 Virtual memory; segment packing INTERNATIONAL BUSINESS MACHINES CORP 11 Nov 1974 [3 Dec 1973] 48633/74 Heading G4A Data are grouped into arbitrary-sized segments S, Fig. 7E, a plurality of which may be packed into partitions P of a single page frame of main store. A pointer register 201, Fig. 4A, supplies a partition offset PO, a segment page field, and a segment displacement field to an adder 203 which combines the partition offset PO with the high order end of the displacement, and, if required, with the contents of an index register 202, to produce a virtual address for locating a segment in a page frame. The virtual address may also include a segment group identifier SGI supplied by the pointer register and designating a group of segments packed in a common page frame, each of the packed segments having a different partition offset PO with respect to that page frame. The virtual address obtained is supplied to a dynamic address translation mechanism 106 in the usual way to provide a real address for accessing main store 116. A new segment is created in response to an instruction which specifies a pointer register (N register) in which a pointer, indicating the address range of the new segment, will be generated; the size Z (in bytes) of the new segment; whether the segment is of fixed or variable length F/V; and an affinity register A which contains the segment identifier of a segment with which the new segment is to be packed if possible. If the A field is zero the new segment is put into a new page frame. Detailed description is given of a system for testing the various fields of the create segment instruction and the pointer register and for testing "packable", "available" and "valid" flags of a header in each page frame 117 whereby only small (not more than one partition), fixed segments, e.g. S1, S2, Fig. 7E, are packed into the first partitions of a common page frame, and large (more than one partition) and variable segments, e.g. S4, are begun in the last partition (P4) of a page frame. Other packing rules are envisaged. Error interrupts are initiated if the validity flag for the portion containing an identified segment in a fetch/store operation is off and if a small segment violates a partition boundary, i.e. the page field of its virtual address is not zero or the highest bits of the displacement field of its virtual address are not equal to the partition offset PO in the pointer register.

Title: Tape wrapping apparatus and method
IPC: B65H81/06
Filed: 1964-12-02
Abstract: 1,093,156. Winding tape on to a core. J. C. THOMPSON. Dec. 2, 1964 [Dec. 13, 1963], No. 48991/64. Heading B8G An apparatus for wrapping tape 94 on to a rotatable body 202 has a support 96 for a roll of tape 98; a rotatable support 56 for the body 202; means 104 for feeding the tape from the roll to the body, which feeding means is adapted to be stopped during rotation of the body; means 14 for pressing the tape against the body 202 and for rotating the body 202 during the tape wrapping 'operation; and severing means 146 for severing the wrapped tape from the fed tape; the tape being kept under tension during severing. A wrapping operation is performed as a result of one reciprocation of a rack 36. At the start of a wrapping operation the rack 36 is at its lowermost position in which it engages a post 78 to force a block 70 and thus the spindle 56 downwardly. This results in spacing of the spindle 56 from the roller 14 by a distance sufficient to permit slipping of a nipple or body 202 on to the spindle 56 below the roller 14. The rack 36 is then moved upwardly and this permits the spindle 56 to move upwardly under the force of a spring, not shown, such that the nipple 202 is pressed against the roller 14. Further upward movement of the rack 36 causes rotation of a gear 18 and pawl 22, but the pawl rides over the ratchet wheel teeth such that the roller 14 is not rotated. The pin 143 deflects the crank lever 126 upwardly with respect to the crank 120, but does not actuate the crank 120. At its uppermost setting the rack 36 operates control means that reverses the direction of motion of the rack. Upon downward motion of the rack 36, the gear 18 is turned oppositely such that the pawl 22 engages the ratchet wheel 16 and causes the roller 14 to rotate counterclockwise as viewed in Fig. 5. Almost simultaneously therewith, the pin 143 at the lower end of the rack 36 engages the lever 126 to deflect the crank 120 downwardly. This results in feeding of the tape 94 towards the spindle 56 and roller 14. Continued downward movement of the rack 36 continues the rotation of the roller 14 and the nipple 202, thereby causing the tape 94 to wrap around the nipple 202. Wrapping continues until the rack 36 has moved downwardly far enough to cause a pin 184 to engage a cam block 166 carrying a knife 146. Downward movement of the block 166 causes the knife 146 to cut the tape 94. Further downward movement of the rack 36 completes the wrapping of the tape on the nipple or body 202. The tape 94 is preferably of polytetrafluoroethylene. The invention is particularly applicable to the wrapping of said tape around externally threaded members to prevent leakage between such member when threaded on to a screw bore.

A television camera comprises a pick-up tube 4, a testing device comprising optical means 16, 18, 22 positioned to one side of the optical axis of the tube and arranged to project an image of a reference transparency 20, and a reflector 8 selectively movable into and out of a position in which the reflector receives the projected image and directs it to the pick-up tube. The reflector may be moved manually; as illustrated it is moved by link mechanism 28, 30 driven by an electric motor 33. When a switch 35 is momentarily closed, a second switch 40 controlled by a plunger 38, which engages the periphery of disc 30, maintains the motor circuit until the reflector occupies its final (inoperative or operative) position where the plunger engages notch 36 or 37. In the operative position of the reflector a switch 24 is operated to complete the circuit for lamp 16 in the optical system of the image projector. Reflector 8 may be a prism. The invention is particularly applicable to a camera using a single variable-focus lens 6, but may be used in a camera having a turret carrying a plurality fixed-focus lenses.

Abstract: 1,240,279. Teaching electro - technology. GRANADA T.V. RENTAL Ltd. 22 Dec., 1969 [21 Oct., 1968], No. 49857/68. Heading G5G. [Also in Division H4] Relates to apparatus for instructing engineers in the operation of and/or detection of one or more faults in electrical equipment incorporating a cathode-ray tube, e.g. a television receiver (colour or monochrome) or a radar set. In the embodiment described, the apparatus comprises a PAL colour television receiver, a display board carrying a block schematic diagram of the receiver, and a desk for use by an instructor with " fault " switches for the selective illumination or extinguishment of different individual blocks or groups or blocks in the schematic diagram and the corresponding production or simulation of different faults in the receiver which affect the image produced on the CRT face. For each block in the diagram a translucent coloured block is provided which may be attached to the diagram by magnetic elements, and with the designations of the blocks only printed on the removable coloured blocks engineers can be tested to place the blocks in the correct positions on the diagram. If desired, the removal of a block may be arranged to extinguish the lamp below that block of the diagram or vice versa, e.g. by reed switches on the display board and magnets on the detachable blocks, the location of the reed switch and magnet being different for each block. During an initial lecture the instructor may illuminate each block in turn. The fault switches control relays connected across selected components of the receiver to simulate short-circuiting thereof, or connected in series therewith to produce open-circuitry in the receiver. The lamps in the display board may be switched off by means of a master switch when the relays are activated so that trainee engineers may be questioned as to where the fault might be, there being provision for testing the voltage at exposed terminals in the receiver. Alternatively, the lamp may be operated independently of the relays so that the trainees can predict what effect a fault would have. Simulation of some faults are effected by applying characteristic voltages corresponding to the faults caused in the displayed picture to the associated terminals or to " false terminals " represented to be the real ones.
