Inventor: ROGERS MICHAEL JOHN
IPC: H03K3/3568
Filed: 1971-11-26
Abstract: An electrical divider for dividing an alternating input signal by an odd integral factor N has N interconnected logic stages. Each stage has two inputs to which are applied the input signal to the divider and an output signal provided by an individual one of the other stages. Each stage includes first and second pairs of transistors arranged such that those of the first pair are biased conductive whenever the signals applied to the inputs concurrently attain a first voltage level, and those of the second pair are biased conductive whenever those voltages concurrently attain a second voltage level. When the transistors in the first or second pair of transistors are both biased conductive then the output of the stage is connected to a supply lead at the second or first voltage level respectively. In this arrangement, the output of each stage alternates at a frequency N times less than the frequency of the input signal.

Title: Method of and an apparatus for producing a core sheath yarn
IPC: D02G3/36
Filed: 1978-07-25
Granted: 1982-02-17
Abstract: A method is provided of producing a core-sheath yarn in which a core yarn is continuously guided in a spinning zone through a gap formed between two adjacent surfaces moving in opposite directions, and staple fibres are fed into the path of the core yarn in such a way that the staple fibres come into frictional contact with the moving surfaces. The core yarn is thereby covered with the staple fibres. The core yarn is guided into the spinning zone at a first defined speed and after covering with staple fibres is drawn off again at a higher second defined speed so as to produce a defined predetermined elastic elongation of the core yarn in the spinning zone. A preferred apparatus for this purpose comprises two rotatable drums (1) each with a porous sleeve in whose interiors are provided air suction devices and between which is defined a narrow gap in which in use the fibres to form the sheath core supplied as individual fibres are collected and spun. A first delivery mechanism (14) is arranged upstream of the drums (1) and a second delivery mechanism (16) is arranged downstream of the drums (1) for the defined supply of the core yarn (3) into the spinning zone and for the defined takeoff of the spun core-sheath yarn from the spinning zone. Means are provided for driving the delivery mechanisms at an adjustable gear ratio. <IMAGE>

Title: Tape transport apparatus
IPC: G11B15/44
Filed: 1978-12-11
Granted: 1982-06-09
Abstract: Apparatus and method for controlling a reel-to-reel tape drive so that its performance characteristics are optimized to best suit the operational mode or availability of a host system by modifying tape speed adaptively according to predetermined conditions sensed during processing of data (i.e., while the tape is in motion). For example, tape might initially be fed at a high speed suitable for archiving; but if more than a predetermined number of "backhitches" (overruns of the interblock gap, IBG) occur during processing of a preselected number of successive blocks of data, the host will cause tape speed automatically to be reduced to a lower rate. This lower rate will enable the tape to stop in the IBG and is therefore suitable for intermittent processing. Preferably, before reducing speed during write operations, appropriate signals are generated at the host to command an increase in the IBG from a normal distance to a larger distance if backhitches exceed said preselected number. If this fails to reduce backhitches to an acceptable level, speed will be reduced to the lower rate and the gap preferably restored to its normal distance.

Title: Colour TV tube with external deflection system - has dynamic correction fields of opposite polarity with intensity as function of angle
IPC: H01J29/70
Filed: 1977-01-20
Granted: 1986-01-20
Abstract: A colour television tube with the electromagnetic deflection system mounted on the outside. The electron beams are produced in one plane and are deflected in planes mutually at right angles. The individual electronic beams are again affected relative to each other by correction fields produced in different planes at right angles to the axis of the tube. The point of intersection of the electron beams will be inside a colour tube in the absence of deflection fields. There are two more dynamic correction fields of opposite polarity which determine the colour selection angle. The intensity will change as a function of the angle of deflection. In principle the value of the passage of the electron beams through the centre of the screen of the colour tube is zero. The direction of the effect on the electron beam by the correction field is the same for each deflection period. The deflection coils on the outside of the tube are made with cores and pole shoes which are symmetrical with respect to the axis.
