Each epicyclic mechanism comprises a sun wheel formed by a plastics track 42, 42<SP>1</SP> on a shoulder 41, 41<SP>1</SP> of gear wheel 38, 39, planet wheels 43, 43<SP>1</SP> and a concentric ring 44, 441 whose teeth 56, 56<SP>1</SP> can be engaged by a pawl 55. A motor (26), Fig. 3 (not shown) drives shaft 36 in direction A whilst the engagement of gears 38, 39 rotates gear 39 in direction B. As shown pawl 55 engages teeth 56 to prevent ring 44 rotating in the opposite direction to A thus causing the planet carrier of wheels 43 to rotate in direction A and drive its associated spool. Simultaneously ring 44<SP>1</SP> is free to rotate and the planet carrier of wheels 43<SP>1</SP> is therefore not driven, but the friction forces generated provide a drag on its spool to tension the ribbon. Over-centre bias on the pawl 55 and plate 58 are provided by springs 85, 87 respectively. Interposers 65, 66 are pivoted at 67, 68 on the plate 58. With pawl 55 engaging ring 44 the ribbon moves in direction 18. As the ribbon is exhausted bar 27 will move lever 30 from position 77 to 78 so that interposer 66 is in path of projections 74, 75, one of which will abut it and move it into its other over centre position. The interposers simultaneously move the pawl 55 into its opposite position to engage ring 44<SP>1</SP> and reverse the ribbon drive.

Abstract: 704,240. Cenfrifugal fans. ENGLISH ELECTRIC CO., Ltd. Oct. 19, 1951 [Aug. 11, 1950], No. 20012/50. Class 110 (1) In order to reduce the noise produced by a fan, a bladed rotor or stator for the fan comprises a number of groups of blades, each group having at least three blades and the blade pitch (i.e., angular spacing between adjacent blades) being constant and equal to that within each other group; but the pitch between the last blade of each group and the first blade of the next group being a half, or an odd multiple of a half, of the blade pitch within the groups. Alternatively, there are at least three blades, all except one of the pitch angles being equal to twice an odd sub-multiple of 360 degrees, the remaining pitch angle being equal to the said sub-multiple or an odd multiple thereof. In the case of a rotor, the resulting unbalance may be overcome by the use of balance weights. Preferably, the rotor and its co-operating stator have different numbers of blades. The rotor or diffuser of a centrifugal fan may be provided with two sets of blades, disposed according to one of the above arrangements and aranged side by side co-axially so that each blade of one of the sets is as far as possible placed at the middle of the pitch angle of the adjacent blades of the other set. Preferably the two sets of blades are separated by means of a disc or annulus.

Title: Tape transport
IPC: G11B15/60
Filed: 1967-05-02
Abstract: 1,128,874. Magnetic-tape transport. AMPEX CORP. 2 May, 1967 [2 May, 1966], No. 20324/67. Heading G5R. A tape transport suitable for use in digital data processing comprises a pair of bidirectionally rotatable capstans arranged to drive a tape directly past a signal-transducing assembly, a pair of buffer chambers disposed such that the path of the tape through the chambers and past the capstans and transducing assembly is always in one plane and that a line drawn across the mouth of each buffer chamber is substantially colinear with a tangent to each capstan and the path of the tape past the transducing assembly, and a pair of tape reels arranged, in use, in a plane adjacent and parallel to the one plane, guide means being provided for guiding the tape from each chamber to a respective reel. As shown in Fig. 1, the system is totally symmetrical. The tape passes from one reel 20 around a rubber-surfaced tachometer drivewheel 24, the tachometer (not shown or detailed), generating signals used in the reel servomotors system. It then passes around roller guides 19 and 17 tilted slightly out of the vertical to provide the transition from the plane of the tape reels to the plane of the buffer chambers and transducing assembly. Then it passes around roller guide 15, into a vacuum buffer chamber 14, around a capstan 11 driven through a flexible belt by a bidirectional motor drive system having a high torque/inertia ratio and past a magnetic head assembly 12 containing separate or combined write and read transducers. The take-up path is analogous. In use, each chamber 14 ensures a capstan wraparound angle of about 180 degrees. A modified construction incorporating cartridge loading is shown in Fig. 5. Here an openbottomed cartridge 37 is removably hinged at 39 to the housing 36. At each end of the cartridge the tachometer drive-wheel is omitted, roller guide 19 is now numbered 44, and roller guide 17 is replaced by roller guides 43, 46. The buffer chambers 14 now lie parallel instead of at an angle, and the reel hubs 30 lie between them. The open ends of the chambers lie along a predetermined tape path defined by capstans 11 and head assembly 12. After the cartridge has been put in position, air is directed from a header 52 to form a loop in each chamber 14. In both embodiments the collinear feature referred to in the first paragraph facilitates tapethreading; the buffer chambers account for disparities between the low-inertia high-speed intermittent tape-drive (intended for digital data processing) and the reel drive; the simplicity of the tape drive system (roller guides 13, Fig. 1, are not included in Fig. 5) reduces wear
