Title: Method and apparatus for recording and reproducing information on a plural-track record disc
IPC: G11B5/596
Filed: 1975-06-27
Abstract: 1474892 Automatic position control BURROUGHS CORP 27 June 1975 27288/75 Heading G3R [Also in Division G5] A transducer with two angularly disposed readwrite heads is located over a circular track on a magnetic recording disc. The two heads simultaneously record the same data in adjacent angularly orientated zones on opposite sides of the centre line of the track. When the data is subsequently read, any time difference between the data sensed by the respective heads is converted into an error signal which is used to maintain the transducer centrally over the track. As shown in Fig. 1, a transducer 4 is driven to a selected track on a disc 2 by a command device 14 and receives input data through an amplifier 12 connected to coils 30a, 30b associated with perpendicular gaps 32a, 32b in the transducer 4, Fig. 2. The data is thus recorded in chevronshaped segments 6a, 6b. During subsequent reading of the recorded data, the head 4b supplies a data output device 24, and both heads 4a, 4b are connected through respective amplifiers 18a, 18b and peak signal detector 20a, 20b to a time difference detector 22, the output of which controls a servosystem 16 for moving the transducer 4 to a central position. Because of the angular orientation of the gaps 32a, 32b, the time difference between the head output signals is directly proportional to the lateral position error of the transducer 4. Variable time delay elements may be inserted in the read and/or write circuits in order to compensate for inaccuracies in construction of the transducer 4, Figs. 7-9 (not shown).

Title: Improvements in and relating to the extraction of juice from sugar cane
Inventor: BOYLE ARTHUR
IPC: C13B10/04
Filed: 1960-08-08
Abstract: In the extraction of juice from sugar cane by means of a crusher and a train of mills through which the crushed cane is passed in the form of a blanket, the raw juice from the crusher and first mill is pumped to a strainer which separates out cush-cush and deposits it on a trough, return juice from the second mill is pumped to the strainer to carry the separated cush-cush in the trough back to the blanket of crushed cane fed to the first mill.  As shown, juices from the crusher A and first mill B are received in a tank 10, and juices from the mills C and D in the tanks 11 and 12. Conveyers carry the cane in a blanket 13. The raw juice from the tank 10 is pumped through a duct 14 to a strainer E in the form of a rotatable drum having walls made of filter panels.  A trough 25 extends axially through this drum and discharges on to the blanket 13 between the crusher and the first mill. The raw juice is fed into the lower part of the drum and passes through it to the outer casing. As the drum rotates, the cush-cush is <PICT:0942817/C3/1> carried upwards and dropped into the trough. Water is fed through a line 27 to the blanket entering the mill D. The thin juice extracted by this mill is pumped from the tank 12 through the line 28 to the blanket entering the mill C. The juice extracted from the mill C is pumped through a line 29 to the trough 25 and carries the cush-cush along it to the blanket entering the mill B.

An air intake for aircraft designed for flight at supersonic speed, comprises opposite walls defining an intake mouth, the mouth leading rearwardly through ducting to an air consuming combustion engine, e.g. a ram jet or gasturbine, one wall having a forwardly directed lip portion and the other wall including a member arranged to extend forwardly of the lip portion so shaped that under design operating conditions shock-wave formations therefrom extend towards a focus near the lip portion of the intake, and a shroud supported externally of the intake mouth and extending at a lower incidence to the air flow than the lip portion of the intake to intercept the shock wave arising from the forwardly-directed lip of the intake mouth. An annular intake, Fig. 1, comprises an annular wall 1 having a mouth 1a and a forwardly facing lip portion 1b. A centre body 2 is supported in spaced relation to the wall 1 to form a duct 3 leading to an airconsuming engine. The forward part of the body 2 is profiled to a point 2a and the surface 2b is shaped so as to direct shock waves C arising from the surface to a focus at or near the lip portion 1b. The lip portion 1b gives rise to a shock wave S1 which is a high angle shock wave because of the high incidence of the wall 1. To reduce the losses associated with the shock wave S1 an annular shroud 4 is supported in spaced relation to the wall 1 so that its leading edge intercepts the shock wave S1 and reflects it through the annular space between the shroud 4 and wall 1. The low angle of incidence of the shroud 4 produces a weaker shock wave S2 which results in a reduction in wave drag. The shroud 4 should be made as short as possible to minimize skin friction. The mutually facing surfaces 4b, 1c are profiled to give a compressive convergent portion 5, a parallelsided portion and an expansion divergent portion 6. The faces 1c, 4b thus mutually extinguish the disturbance caused by the other; shock waves produced by the wave 1c being cancelled by the aid of face 4b. The intake is described applied to a conventional gas-turbine engine and to a by-pass engine. The engine may be applied to a rectangular intake.
