Inventor: GOUBAU G
IPC: H01Q15/02
Filed: 1959-10-29
Abstract: 923,202. Waveguides. G. J. E. GOUBAU. Nov. 4, 1959 [Nov. 21, 1958], No. 37418/59. Class 40 (8). [Also in Group XL (c)] Electromagnetic energy is confined to a substantially cylindrical beam by means of phase-correcting plates spaced along the beam. Reflector 21, Fig. 4B, converges slightly radiation from feed 21<SP>1</SP>. Due to diffraction the beam is diverging when it reaches the first of a series of phase-correcting plates 19 which cause it to converge again, the process being repeated at subsequent plates. The feed may be reversed and the reflector replaced by a lens. Reflection at the phase plates is minimized by forming them as a pair of plano-convex lenses back-to-back, or making them of multiple dielectric in annular or shell-like sections or of a plurality of conducting tubes of the order of a wavelength in diameter. Alternatively, they have #/4 dielectric coatings or suitable conductors embedded in them. The beam may be bent through a small angle by a dielectric prism or a large angle by a metal reflector. Waves along path 22, Fig. 5, polarized in the plane of the paper may be transmitted with and independently of perpendicularly polarized waves 23 reflected in direction 22 by grid 24. Beams of different diameters may be coupled by optically imaging the last phase plate of one system into the first of the next. The system may be enclosed in a concrete pipe 31<SP>1</SP> and run underground.

Title: Device for locating blockage in a pipe
Inventor: HOLMGREN ALLAN J E
IPC: H02G1/00
Filed: 1978-09-15
Abstract: Device for locating blockage and the position of the same in hidden pipes, e.g. of the type that are used for drawing electric cables in e.g. walls, with use of a transmitter and a receiver. As such pipes lie completely hidden inside of a wall or similar it is difficult to localize a blockage in such a pipe and for this an induction coil or similar connected to a pulse generator is used and fed into the pipe until it is stopped by the blockage, after which the position of the induction coil is sensed by a receiver equipped with an induction coil tuned into the transmitters induction coil. For enabling the induction coil to be inserted into such relatively narrow and bending extended pipes the induction device for the transmitters induction coil (3) is on a helical-shaped spiral spring (6) at whose end the induction coil is arranged with a core (7) which is made up of one end of the spiral sprung part of the spring forming wire, around which the part of the induction coil's winding (9) is wound on a winding (9) from the core's (7) shielded insulation coating (8).<IMAGE>

Title: Formation wire cloth
Inventor: STROM J
IPC: D21F1/10
Filed: 1982-04-27
Abstract: This device refers to a formation wire cloth for a machine that manufactures absorbent cotton, tissue, non-woven and so on by dewatering and formation of a fibre suspension, which wire cloth consists of longitudinal and transverse threads which connect with each other and can be one or more layers. In some types of fibre sheets one wants to achieve a characteristic pattern. The pattern is achieved by means of making the fibres distribute densely and respectively sparsely in areas that are laid based on a controlled system. The purpose of this formation wire cloth is that it has such a structure that it gives the fibre suspension dewatered on the wire cloth a characteristic pattern with denser areas alternating with sparser areas which if so desired can also consist of hollow spaces. The wire cloth has thus systematically distributed surface areas 3, 4, 6, which can have any size (e.g., the same size) in which surface areas the number of breakthrough points between the longitudinal threads 1 and the transverse threads are from zero up to essentially less than what applies for the wire cloth's binding structure otherwise.

Title: Queuing buffer device for a processor system where several processors use a common memory
Inventor: KJOLLER H O S
IPC: G06F15/16
Filed: 1983-04-26
Abstract: Queuing buffer device for a processor system where several processors use a common memory and where series of blocks of programs, each consisting of program and data are executed in a dynamically determined order by the processors.  After a program block is processed, a signal word is generated, which contains a program block address; this is written into a FIFO queue buffer which is read by a free processor, and thus this program block can move into various program block series or transaction packets.  These are processed at approximately the same time by the processors in the system.  The queue buffer device includes a marking circuit (EK) which provides the signal words to every transaction packet (T1, T2 etc.) with a flag word which corresponds to the transaction packet's number in the program block it is temporarily part of.  The queue buffer device includes a first switch (V1) to sort the signal words obtained from the entry buffer into the first queue buffers (KT1, KT2 etc.) each corresponding to a determined transaction packet number and a second switch (V2) to sort the signal words obtained from the first switch into the second queue buffers (KB1, KB2 etc.) each corresponding to a determined program block number. The signal word is fed from these second queue buffers to an exit queue buffer (GB), which is accessible to all processors (PRO1, PRO2 etc.). A control register (ST) is designed to pass a signal word from the first switch (V1) and a signal word from the second switch (V2) corresponding to the transaction packet number and block number of a completed program packet, so that the exit queue buffer (GB) only contains signal words with different program block numbers and their associated different transaction packets.<IMAGE>
