Patent GB-2114469-A (GB)
Title: Flotation apparatus
Inventor: WEBER RICHARD BAXTER
IPC: B03D1/16
Filed: 1983-01-11
Abstract: A flotation machine consists of a flotation chamber and a rotating gas diffuser. The flotation chamber has a lower mixing chamber and an upper quiescent zone for maximizing float accumulation. The rotating diffuser produces ultra fine bubbles as small as 50 microns in diameter. The size of the bubble diameter can be controlled and produced in any size from less than 50 microns to greater than 10 mm to enable flotation of various materials and/or various sized fractions of materials. The ultra fine bubbles are produced by the diffuser in the same size range as bubbles produced by dissolved air flotation, but without the necessity of pressurizing gas in a first tank followed by depressurizing in a second tank. Since the diffuser is located within the flotation chamber and can vary bubble size, it also provides the advantage of sparged air flotation. This rotating diffuser configuration is a low drag thin disc and, when combined with a specially designed flotation chamber, embodies a flotation machine which produces higher product yields over a wider range of feed size fractions utilizing significantly less energy.

Title: Television display system with reduced line-scan artifacts
Inventor: POWERS KERNS HARRINGTON
IPC: H04N5/44
Filed: 1982-08-31
Abstract: A flat-field television image having reduced visibility of horizontal scan lines is generated by receiving first and second fields of interlaced video and progressively generating a scanned image within a time for one incoming field. The progressively scanned image contains interstitital lines between the lines of one field, and consequently the line-scan structure is made less visible, but the flicker rate is undesirably decreased. In order to increase the flicker rate, additional progressively scanned images are generated at a rate equal to or greater than the incoming field rate.
Patent GB-2139852-A (GB)
Title: Data network
Inventor: SHORTLAND MICHAEL THOMAS
IPC: H04L12/64
Filed: 1983-05-13
Abstract: In a closed loop telecommunicationssystem, e.g. for use in a PBX, the loop interconnects a number of nodes each of which serves at least one terminal. The loop includes a long shift register or other storage device via which all messages in the loop pass and which ensures that the loop's time cycle exactly equals the interval between two consecutive speech samples. It also ensures that this cycle time provides an integral number of pulse times. Normal speech connections are set up by circuit-switching in which each call uses one time slot, with the setting up message sent in packet mode from the calling to the called mode. Packet mode uses one or more slots into which a packet is fitted, the slots used to convey a packet being so chosen as not to interfere with any circuit-switched connection. <IMAGE>

Title: Group supervisory control apparatus for lift system
Inventor: YONEDA KENJI
IPC: B66B3/00
Filed: 1983-09-08
Abstract: A plurality of characteristic modes represent traffic demand states occurring in a building in which the system is installed. When a detected traffic demand state coincides with one of the modes, operation of the system is controlled with the aid of control parameters determined thereby so that the currently detected traffic demand is processed in an optimal manner. The modes are stored and selectively read out in response to traffic demand detection. A mode creating and modifying capability accommodates new traffic demand states through a learning procedure, a mode being established by an automatic learning procedure in dependence on the results of evaluation of the traffic demand characteristic with regard to the significance, the time or period and continuity thereof. To this end, a disconnectable learning microcomputer is provided in addition to the system operation and car controlling microcomputers. Special modes can be manually input at a terminal. <IMAGE>

Title: Pulse generator with magnetic polarisation reversal
Inventor: BETHGE KARIN
IPC: G01P3/487
Filed: 1984-11-02
Abstract: A pulse generator is described in which electric signals are induced, by reversal of magnetisation of a Wiegand wire (6), in a pick-up coil (7) which coaxially encloses the Wiegand wire (6) and in which the reversal of magnetisation is effected at the Wiegand wire (6) by the close relative movement of a plurality of magnetic poles (10, 11) with differing polarity. The Wiegand wire (6) is oriented relative to the magnetic poles (10, 11), which are being moved past it, in such a manner that one of its two ends is exposed to the magnetic field of these magnetic poles (10, 11) to a greater extent than the other end. For compensating the signal induced, additionally to the Wiegand signal, in the pick-up coil (7) by the magnetic poles (10, 11), a compensating coil (12) is provided which coaxially surrounds the Wiegand wire (6), is connected in series with the pick-up coil (7) and is exposed to the magnetic field of the magnetic poles (10, 11) in the vicinity of the pick-up coil (7) in a winding direction which is opposite to that of the pick-up coil (7). An optional guide plate (8) is used for signal amplification in coils (7) and (12). In the embodiment of Figure 2a the poles (10, 11) are mounted on a rotor (2), but a linearly moving pole arrangement may be used also. <IMAGE>

Title: Image processing apparatus
Inventor: TANIOKA HIROSHI
IPC: H04N1/41
Filed: 1984-12-20
Abstract: An image processing apparatus capable of faithfully reproducing picture (half tone) image data, character (line) image data and dot image data by distinguishing from input image data the nature of the original image. The image data is discriminated by the distribution of its spatial frequency. 
<??>In a first embodiment the input image data is processed in blocks of M x N pixels eg. 8 x 8 pixels. The density of each pixel in each block is binary digitised (step 3) and the sum S of the number of transitions of binary levels in two dimensions between immediately neighbouring pixels is determined. The sum S for each block is then compared with predetermined values P1 and P2 to discriminate the nature of the image. if S </= P1 then it is discriminated as a picture image area and subjected to a dither process (step 8). If P1 < S </= P2 then it is discriminated as a character image area and the binary data from step 3 passed without further processing (step 7). If S > P2 then it is discriminated as a dot image area and the densities of the pixels in the block are replaced by the average density thereof (step 6) and then subjected to dither coding (step 9). The resulting outputs are combined and fed to an image memory (step 10). 
<??>In a second embodiment the discrimination is effected using the sum T of the absolute values of the differences between immediately neighbouring pixels in each block instead of the sum S. In a third embodiment an image tone parameter PS = T/ DELTA D max is used to effect the discrimination, where  DELTA D max is the difference between the max and min densities in the block.
