Title: Drilling boom
Inventor: HEDGES RAYMOND
IPC: E21B15/04
Filed: 1985-02-14
Abstract: A drilling boom 10 is pivoted about a first axis 12 or 14 on a base and is pivoted about that axis by a first hydraulic cylinder 15 or 17. It carries a feeder beam carrier 21 at its forward end. The carrier 21 is pivoted at the forward end of the boom 10 about a second axis 22 or 24 which is parallel to the first axis 12 or 14, and it is moved about the second axis 22 or 24 by a second hydraulic cylinder 25 or 28 in a sense opposite to that in which the boom 10 is moved by the first cylinder 15 or 17. The first and second cylinders are so dimensioned and hydraulically interconnected that fluid which is expelled from the first cylinder 15 or 17 actuates the second cylinder 25 or 28 and vice versa.

Title: A winding mandrel for forming flattened balls of yarn
Inventor: ARENDT GERHARD
IPC: B65H54/66
Filed: 1985-03-01
Abstract: The mandrel has an end piece (5) mounted on a shaft, a first set of arms (6) articulatedly mounted on and spaced around the end piece (5), a head piece (7) displaceable coaxially in relation to the shaft and a second like set of arms (8) articulatedly mounted on the and spaced around head piece. The arms of the first and second sets of arms are directly and articulatedly connected to one another at their free outer ends and form a winding body, which when the end piece (5) and head piece (7) are relatively closer together has a smaller axial (shaft-direction) dimension and so is suitable to support, and permit build up of, a flattened ball of yarn or the like, but when the head piece 7 and end piece 5 are farther apart contracts in transverse dimension to permit removal of the wound flattened ball. The arms may be covered by a flexible member. Such arms may be replaced by a resilient moulded member disposed between and fixed to the end piece and head piece, having the same support and shape characteristics as the connected arms. <IMAGE>

Title: Compound horn antenna
Inventor: BOYLAN DAVID
IPC: H01Q13/02
Filed: 1986-03-18
Abstract: In a broadband compound horn antenna it is desirable to suppress the TE30 mode whilst allowing the propagation of the fundamental TE10 mode. A broadband compound horn antenna is disclosed having opposed ridges 15 and 16 extending, in the E plane, centrally from opposite major faces. The spacing d varies with the axial distance L along the tapered transition 12 as the fourth or greater power of L. Such a profile has been found to gradually reduce the cut off frequency for the unwanted TE30 mode and thus finally suppress the propagation of this mode. <IMAGE>

Title: A real time input device for handwritten chinese characters
Inventor: JIN YIPING
IPC: G06V10/12
Filed: 1986-03-27
Abstract: A real time input device for handwritten chinese characters comprises a matrix of mutually perpendicular and insulated row and column conductors and a pen-like object with a conducting head. When the pen head touches the plane of the matrix, rows and columns are connected. As a character is written the pen head is moved on the matrix and the coordinates thereof are changed accordingly. The stroke can be recognized by distinguishing the direction and the distance of the movement of coordinates. Recognition is carried out using a small amount of internal memory, only 16 binary digits for the internal code of each character, the possibility of using different sequences of strokes for some characters, no multi-character code for output. These are achieved because two transformations of the primary codes, and indexing pages by radical codes are employed. <IMAGE>

Title: Wheel examination
Inventor: HIRANO AKIRA
IPC: G01M17/06
Filed: 1991-02-08
Abstract: A method and apparatus for examining a wheel (1) of a vehicle is provided. A support roller assembly (30) supports a wheel (1) both for translational as well as rotational movement in a plane when unlocked. A wire (35) extends between the free end of the reciprocatable rod (54b) of a cylinder actuator (34a) and the support roller assembly (30). When the rod (34b) is located at its extended position, the wire (35) is slack to establish a static examination mode of operation, in which the support roller assembly (30) can move freely in a plane without constraints. Under this condition, the static characteristic of the wheel is measured and adjusted, if necessary. When the rod (34b) is located in its retracted position, the wire (35) is under tension, and the cylinder actuator (34a) is operatively coupled to the support roller assembly (30) whose movement is controlled by the wire (35). Thus, a dynamic examination mode of operation is established. In this state, the wheel (1) is rotated and the dynamic characteristic of the wheel is measured and adjusted, if necessary. <IMAGE>
