Abstract: 1,053,923. Magnetic tape data stores. CALIFORNIA COMPUTER PRODUCTS Inc. May 21, 1963 [May 21, 1962], No. 20256/63. Heading G4C. The clocking of apparatus including a magnetic tape data store is controlled either by clock signals derived from the tape output signals (i.e. a self-clocking system), or by a separate pulse generator. The pulse generator, as shown, comprises a 100 kc./s. multivibrator which may control the generation of the clock pulses by units 22, 23, 25, 26. Such control is normally exercised for a period (e.g. of  or ¢ second) controlled by units 30, 31 while the tape transport mechanism is changing speed, after which control is transferred to the tape itself, operative over lines R1, R2, R3. Unit 22 or 23 is selected, according to tape speed, to provide a delay for the clock pulse to eliminate difficulties due to skewed tape. The tape may be searched for a desired block of data, inserted at 36 and compared at 38 with the address of the block being read and when such block is found the control panel may then be operated to initiate a graphical 2-dimensional plot of data in the block. Other aspects of the system are the subject of Specifications 1,053,921, 1,053,922 and 1,053,924.

In Fig. 1 the trolley 3 which has blowing ducts 9, 10 and an intake duct 11 is provided with a flywheel drivable through a shaft 7 and disc 8. At one end of the travel of the trolley the disc 8 is brought into contact with a driven disc 8a and the flywheel accelerated. At the same time fly which has accumulated in a filter box 15 on the trolley is automatically drawn away via a reception member 17 to a suction box 20. In Fig. 2 the trolley is provided with an accumulator which is periodically connected to an electrical supply by fixed contacts 23 and contacts 22 on the trolley. A motor 21 is provided on the trolley to be energized by the accumulator and to drive the trolley and the pneumatic fan. In a further form an electric motor, intermittently connected to a supply, is provided on the trolley to bring a flywheel thereon up to speed. The outlet air from the trolley may be used to assist or wholly provide the drive for the trolley. An additional fan may be provided for this purpose and the direction of the air jet may be reversible. If the trolley runs on an endless track contact rails may be provided over a length of the track whereby current can be lead to the trolley, if desired without halting the trolley. In a further arrangement an electric motor on the trolley may be used to accelerate the flywheel, and then as a generator driven by the flywheel to supply current for one or more motors driving the trolley and pneumatic fan. A compressed air vessel could be used as an energy store and such air could be used for cleaning.

Abstract: 1,229,007. Gas turbine ducted fan engines. ROLLS-ROYCE Ltd. Nov.27, 1969 [Dec. 4, 1968], No.57599/68. Heading F1J. A gas turbine ducted fan engine comprises an inner duct in which are located a gas turbine type gas generator and a separate turbine driven by gases from the gas generator, and an outer duct in which are located two fans axially spaced apart so that in operation substantially no wake interaction occurs between them, one of the fans being drivingly connected to the gas generator and the other being drivingly connected to the separate turbine. The engine shown comprises an inner duct 12 in which are located in series flow an LP compressor 15, IP compressor 26, HP compressor 16, combustion equipment 17, single stage HP turbine 18, three-stage IP turbine 19, singlestage LP turbine 20 and three-stage separate power turbine 35, the HP, IP and LP turbines being connected to the HP, IP and LP compressors by shafts 22, 24, 23, respectively. The IP compressor 26 comprises also a rotatable wall portion 27 on which are mounted inlet rotor vanes 30 and interstage vanes 29, the inner fairing portion 31 being connected to the inner ends of the inlet rotor vanes 30. A fan duct 13 is disposed around the inner duct 12 and in it are disposed an upstream fan 40 and a downstream fan 45, rows of stator vanes 48 and 49 being disposed between the two fans and a row of outlet guide vanes 50 being disposed downstream of the fan 45. The upstream fan 40 is drivingly connected to the IP compressor 26 and so to the IP turbine 19, by a drive connection 41. The downstream fan 45 is drivingly connected to the separate power turbine 35 by a drive connection 46 connected to the outer ends of the second stage blades 37 of the separate turbine.

Abstract: 1,232,267. Extendable link for connecting an implement to a tractor. BARSYKE Ltd. 13 Feb., 1970 [15 Nov., 1968], No. 54199/68. Addition to 1,095,633. Heading A1P. [Also in Division E1] In order that the extendable link of Specification 1,095,633 may be packed into the smallest possible space for despatch from the manufacturers to a customer the handle 30 of the latch for locking the two members of the link together is now removable from or movable with respect to the latch from the operative position shown to an inoperative position alongside the link. As shown the handle is mounted on and is rotatable about an exposed end of the pivot of the latch when the handle is not locked to the latch by a screw or spring pin 42.
