Title: A method of producing a bracket for a motor vehicle
Inventor: BECK STEWART DUDLEY
IPC: B60K17/24
Filed: 1988-09-28
Abstract: A method of producing a bracket (22 or 23) for mounting a bearing (20) of a driveline (18) to a motor vehicle, the bracket comprising a portion having a substantially L-shape defining a substantially horizontal limb (27) attachable to the bearing and a substantially vertical limb (25, 28) having apertures associated therewith for securing the bracket to the motor vehicle with bolts 26; the method comprising the steps of determining the required height (H) of the apertures associated with the substantially vertical limb relative to the substantially horizontal limb for the motor vehicle on which it is to be fitted from a look-up table in a computer; and forming the bracket in accordance with the determined required height. Allows large reduction in component parts for an assembly line. The two parts (24, 25) of the bracket are secured together (e.g. by welding or rivetting) at relative positions giving the required height. In an alternative embodiment, the bracket is in a single piece, and the apertures are formed in the vertical limb at locations giving the required height. <IMAGE>

Title: A two/four wheel vehicle drive system
Inventor: IRITANI HIROFUMI
IPC: B60K17/348
Filed: 1989-04-06
Abstract: A four-wheel drive work vehicle, e.g. an agricultural tractor, is selectively drivable in a standard four-wheel drive mode (4WD-I) in which all wheels are driven at the same speed, an accelerated four-wheel drive mode (4WD-II) in which the front wheels are driven faster than the rear wheels and in a two-wheel drive mode (2WD), by movement of a shift fork (17) which is biassed towards position 4WD-I and is shiftable linearly to the other positions. A cam (22), whose shaft (21) is connected to the steering input, is movable by a link mechanism (A) between an operative position, in which it pushes the shift fork (17) from 4WD-I to 4WD-II when a predetermined steering angle is exceeded, and an inoperative position clear of the shift fork (17). For greater operator convenience, the link mechanism (A) has a third condition in which the cam (22) is moved to its inoperative position and the shift fork (17) is moved to the 2WD position. The camshaft (21) may pivot with the steering pitman arm (50, Fig. 11). The driver's seat (29, Fig. 10) may be pivotable to act as a lid for an opening (32) in a floor panel (30).

Abstract: A magnetically tunable microwave resonator comprises a resonator block (11) made from a ferrimagnetic material. The effective permeability, and so the resonant frequency, of the resonator block can be altered by subjecting the block to a magnetic field bias which could be an external continuous magnetic field bias obtained from a coil 20, polo pieces (30, 31 Fig 3) or C-shaped ferrite cones (51, 51' Fig 5) or an internal, latched magnetic field bias obtained by a longitudinal or transverse current carrying wire (40, Fig 4). The inner and outer side surfaces of the block 11 are provided with metal layers 13, 14 eg silver, copper or aluminium. In a modification (Fig 6b) the resonator block may be of two axial sections (62, 63) one being of ferrimagnetic material and the other being of ceramic material. In a further arrangement two coaxial cylinders (60, 61, Fig 6a) may be used having the inner one of ferrimagnetic material and the other one of a high dielectric material. Magnetically tunable microwave filters are described (Fig 7a-7d) including a plurality of the magnetically tunable microwave resonators. <IMAGE>

Title: Optical printing system
Inventor: YAMAMOTO TAKEMI
IPC: B41J2/48
Filed: 1990-01-16
Abstract: In an optical printing system for printing an image on a recording sheet, adopted as the recording sheet is a sheet coated with microcapsules on one surface thereof. Each microcapsule envelopes a first component which change color when reacts with a second component. The second component may be coated on the recording sheet or may be coated on a separate developing shoot. The microcapsule further envelopes a third component which varies the mechanical strength of microcapsule when light is projected thereto. An image is formed on the recording sheet by selectively exposing a light thereto in accordance with the image to be printed thereon, and the microcapsules on the recording sheet whose mechanical strength is low are then ruptured by rupturing means. Thereby, the color is developed or the recording sheet on the separate developing sheet by the reaction of the first component with the second component. The microcapsules are of three types, corresponding to three colours. Radiation of three wavelengths appropriate to the three types of microcapsule is provided at once.
Patent GB-2240632-A (GB)
Title: Torque impulse unit
Inventor: DUDDEN CHRISTOPHER JOHN
IPC: B25B23/147
Filed: 1990-02-06
Abstract: An inertial mass 6 carried by an input member 2 of a hydraulic impulse clutch 1 is subjected to an accelerating force in the frame of reference of the input member 2 during transmission of a torque impulse to an output member 3. When a bit coupled to output shaft 23 is located on a nut or screw to be tightened a spring 24 is compressed and a push rod 19 which is engaged with the abutment surface 21 of a latch plate 17 causes the motor to start. The clutch 1 is rotated in the direction of arrow a and the screw or nut is tightened until the resistance to tightening causes output shaft 23 to slow down or stop, whereupon input member 2 is disconnected from output member 3 of shaft and the input member 2 accelerates. After one revolution member 2 abruptly reconnects to member 3 and applies a torque impulse to output shaft 23. Repeated impulses are applied until the deceleration of member 2 is such that the acceleration force applied to inertial mass 6 is sufficient to cause its arm 6b to push a ball 13 back against adjustable spring 12 and move latch plate 17 against spring 16 so that the abutment surface 21 is released from the push rod 19. The push rod moves through an aperture 27 in latch plate 17 and causes the motor to stop at the required torque value. <IMAGE>

The remaining uncut length of wall acts as a spring hinge 9 and also provides the restoring force to tend to close the product around the item so that clamping bands can be fitted easily. Where the wall of the hinge section is too thick to perform effectively, a third partial severance 7, is introduced from the interior surface 3 to reduce its effective thickness such that the hinge section 9, is then enabled to perform effectively. <IMAGE>
