Title: Semi-active vehicle suspension control system with variable damping
Inventor: KAKIZAKI SHINOBU
IPC: B60G17/015
Filed: 1990-07-10
Abstract: Suspension characteristics are adjusted between hard and soft for bounding and rebounding stroke independently of each other. Sensor means monitors vertical speed of a vehicular body as a sprung mass relative to a wheel for producing a vehicle body speed indicative signal variable of signal polarity depending upon the direction of vibration, and sensor means for monitoring vertical acceleration of the vehicular body which is also variable of signal polarity depending upon direction. A control unit adjusts damping characteristics for bounding and rebounding vibration depending on the phase relationship between the signals. An adjustable damper 20 which may be used has a "bounding" fluid flow path 22h and a "rebounding" flow path 22m. A rotary actuating rod 27 controls a rotary valve member 26 having radial orifices to vary the damping. <IMAGE>

Title: Regeneration of Fischer-Tropsch catalysts
Inventor: BELL WELDON KAY
IPC: B01J38/06
Filed: 1990-08-24
Abstract: The medium pressure Fischer-Tropsch synthesis of liquid hydrocarbons conducted with an iron catalyst is made more efficient by temporarily suspending conventional synthesis and treating the catalyst with a high partial pressure of water vapor, after which conventional synthesis is resumed. The treatment imparts a large increase in selectivity for liquids with reduction of methane formation. The treatment is very effective with alkali (e.g. potassium) promoted precipitated iron catalyst; the exemplified catalyst also contains copper.

Patent GB-2275969-A (GB)
Title: Hydraulic intensifier
Inventor: HOLMES BARRY
IPC: F04B9/115
Filed: 1993-03-01
Abstract: A hydraulic intensifier for converting a relatively low pressure liquid supply to a high pressure supply in circumstances - sub sea control of oil well valves - where the required pressures are extremely high (e.g. "low pressure" is typically 3000 psi). LP liquid is fed to the HP cylinder 22, 24 of a differential piston arrangement and compressed to the required HP by LP liquid in the LP cylinder 18, 20. Duplicate differential pistons are used, coupled together by an intervening pilot slide valve 3. Each piston draws in LP liquid at the same time as driving the pilot valve and compress the other HP cylinder liquid. At the end of the piston and valve stroke the pilot valve feeds LP liquid to changeover a changeover valve 8 which feeds LP liquid to drive the other LP piston. The changeover valve is latched by hydraulic feedback to maintain its position and the supply of LP liquid to the driven piston throughout its stroke. The two valves use shear seals and duplication of feed ports to balance hydraulic forces on the valve sliders. <IMAGE>

Title: Ultrasound apparatus and method for securing or removing a prosthesis
Inventor: THODIYIL PAUL ALBERT
IPC: A61F2/46
Filed: 1993-04-19
Abstract: A method of securing a prosthesis to a bone includes inserting cement into a cavity formed in the bone, locating the prosthesis in the cemented cavity and, before the cement sets, applying ultrasound to the cement through the prothesis at a frequency and for a time to substantially eliminate folds and inclusions in the cement. The ultrasonic frequency may be c. 20KHz. Alternatively, a cemented prothesis may be removed by applying ultrasound thereto firstly at a frequency to cause fatigue fracture of the cement-bone and cement-prosthesis bonds, then at a frequency to cause cavitation in the interface and finally at a frequency to cause thermal softening of the cement. The ultrasound apparatus used may include a magnetostriction transducer 20 connected to a conductive body 10 which has adjustable jaws 12 for gripping the prosthesis 4, and means for controlling the resonant frequency of the transducer. <IMAGE>

Title: Paper storage and feeding in ink jet printers.
Inventor: SAITO KAZUO
IPC: B65H29/70
Filed: 1993-09-10
Abstract: In a printer, a store for cut sheets and a feed mechanism for feeding them successively to the printing station are built into the machine housing such that the base of the paper feeder is also the base of the machine housing. As shown, a plate 230, on which a stack of paper may be placed, is pivotally engaged with the casing at the rear end, and is urged upwardly by a spring 233 whereby to engage the topmost sheet against a feed roller. Associated with the plate (one each side) are a pair of levers 240 pivoted to the machine at 243 and having respective detaining members 241 for engagement under the bias of spring 246 with respective corners of the leading edge of the topmost sheet, to control separation of the sheet when the feed roller rotates. An abutment 242 on lever 240 engages the paper lifting plate 230. When paper is inserted, a flap 260 is raised, which depresses the rear end of lever 240. This in turn depresses the plate 230 and raises the detainers 241 (i.e. as shown in Fig 12) to provide easy access for the paper. Also disclosed in detail are:- mechanisms responsive to the position of the printhead carriage for selecting paper feeding and nozzle purging modes. interengagements between an ink cartridge and the printhead, papertensioning arrangements associated with an ink shield and a paper presser. paper discharging arrangements which distort the paper transverse to its motion. <IMAGE>
