Title: Motor cycle fork air pressure equalizer
Inventor: RYDER BERNARD GEORGE
IPC: B62K25/06
Filed: 1985-06-22
Abstract: The motor cycle fork air pressure equalizer, as shown in Fig. 5, consists of two oil stopping valves 14, two flexible pipes 12 and an air valve holder 10. It is easily fitted to the top of the fork legs 26 by means of the existing valve holders 24. When assembled air is pumped in, because the air is governed by one air pressure valve and the oil stopping valves let air pass through both ways, equal air pressure is maintained in both fork legs. If the motor cycle, by accident, is turned upside down or laid over allowing the damping oil to reach the top of the fork leg, the oil stopping valves prevent any oil getting past. <IMAGE>

Title: A method and apparatus for locating and displaying historical information within an electronic postage meter
Inventor: HILLS KAREN F
IPC: G06F11/14
Filed: 1986-09-11
Abstract: A system is provided for locating and displaying a most recently written record in an electronic postage meter to sequentially store accounting data associated with the transactions of the electronic postage meter. The meter includes a first non-volatile memory (NVM) and a second non-volatile memory (NVM). The system includes apparatus for locating an accurate piece count within the second NVM, for utilizing the accurate piece count within the second NVM to locate a written transaction in the first NVM, and means for providing an external message generated by a keyboard or the like. Accordingly, the written transaction represents the most recently written record in the postage meter. The system also includes a means for determining whether the record is accurate. Accordingly, check values are provided as part of the record in the first NVM. If the check value and a value corresponding to the written transaction agree, the record within the first NVM will be displayed to a user. If the values disagree, an error indication will be displayed to the user. A key sequence on a keyboard or the like within the electronic postage meter can be depressed to either display ascending or descending register information, as the case may be, depending upon which portion of the first NVM the user would like to access. This system can be utilized in a repetitive manner to access and display sequentially stored information within the first NVM and to verify the accuracy of the stored information.

Title: Solid-liquid separators
Inventor: LEVDANSKY EDUARD IGNATIEVICH
IPC: B04C5/10
Filed: 1986-12-06
Abstract: A solid-liquid suspension flows along the inside of a fixed perforate tube 1 from inlet 9a while gas fed in through inlet 9 is caused by vanes 17 to swirl, inducing a similar swirl in the suspension so that centrifugal forces force the liquid component through the tube wall to outlet 11. In Fig. 2 a second, heated whirling gas stream is admitted further down the tube, so that almost dry solids reach outlet 16. In Figs. 3, 4 vanes outside tube 1 induce whirling there, and in Fig. 5 the gas from outlet 12 and from another outlet below plate 13 is recycled. Figs. 6, 7 show two-stage separators. The gas may be air, heated or not, for drying polymer particles. When crystals are being recovered from a solution, steam-humidified gas is used, to preclude evaporation of liquid and consequent fine crystal formation. <IMAGE>

Filed: 1987-05-27
Abstract: Apparatus for and methods of forming airlaid fibrous webs having a multiplicity of layers and/or discrete particles of absorbent gelling material dispersed through at least a portion of the web. The apparatus (20) is of the type which includes an airlaying means (34,46) such as a laydown drum (100,110) having a foraminous forming element; a first or primary deposition means (36) for directing a first or primary stream (54) of air-entrained fibres to the laydown drum (100); a first or primary hood (38); a dusting layer deposition means (42) for directing a dusting layer stream (56) of air-entrained fibres to the laydown drum (100) wherein the dusting layer stream is deposited onto the laydown drum (100) prior to depositing the first or primary stream (54) on the laydown drum (100) and a dusting layer hood (44). The dusting layers (1012) acts to block the passage of particles or fibres entrained in the first fibre stream (54) so as to minimize equipment plugging problems and the loss of particles or fibres through the foraminous forming element. In addition, the first vacuum chamber (126) in the laydown drum (100) spans the first hood (38) and a portion of the dusting layer hood (44) so that the dusting layer (1012) is not sheared off, damaged, or destroyed as the laydown drum (100) rotates to the position where the first fibre stream (54) is deposited over the dusting layer (1012). The method preferably comprises the steps of:   a. providing multiplicity of streams (54,56,58) of air-entrained fibres: b. directing a dusting layer stream (56) of air-entrained fibres to an airlaying means (34); c. forming a dusting layer (1012) on the airlaying means (34) from the dusting layer stream (56) of air-entrained fibres; d. directing a first stream (54) of air-entrained fibres to the airlaying means (34); e. forming a first layer (1014) over the dusting layer (1012) on the airlaying means (34) from the first stream (54) of air-entrained fibres. e

Title: Device for the digital processing of images to obtain special geometrical effects
Inventor: ARTIGALAS MAX
IPC: H04N5/262
Filed: 1989-06-02
Abstract: The obtaining of a geometrical effect, with an image, is done by means of a two-dimensional filter (F) with variable characteristics controlled by a computer (1) to compute the points of a pre-established conversion grid (Y, V), superimposed on the image, as a function of neighbouring points of the original image defined with respect to a rectangular grid (X, Y) and of the desired effect. A known way of performing of these computations is by means of a memory (M0). Auxiliary images, obtained by successive reductions in cascaded fixed 2D filters (F1...F3), in a fixed proportion, of the original image, are stored (M1 - M3) and a point is computed by selecting (change over switch 2) that one of the memories (M0 - M3) for which the reduction factor enables the easiest computation while, at the same time, preserving the quality of the image.
