Title: Arrangement for Blocking a Vehicle Clutch
IPC: B60W30/18
Filed: 1980-08-29
Abstract: An arrangement for holding a vehicle clutch in a position disengaging torque transmission between an engine and a gearbox, a hydraulic circuit being arranged for clutch operation to transfer movements between an operating means (7, 9) and at least one means (11, 14) actuating the clutch. A blocking valve (21), incorporated in the hydraulic circuit, has a non-return valve function regulated by a gear position sensor (24, 36) to allow flow of hydraulic medium in a direction from the operating means (7, 9) to the actuating means (11, 14) and to block the passage of hydraulic fluid in the opposite direction when a gear is not engaged in the gearbox. The operating means can be a clutch pedal (7) and the activating means a servo unit (11), the clutch pedal being articulatedly connected to a hydraulic piston (8) in a hydraulic cylinder, which in turn is articulatedly connected via the blocking valve to a hydraulic- pneumatic servo unit (11) attached to the vehicle and adapted to perform the actual disengagement work on being activated. The blocking valve comprises pressure-medium regulated control means (37, 53) by means of which the holding function of the blocking valve (21) can be disengaged when a gear is not engaged in the gearbox. In Figure 1 a gear selector 3 controls the movement of a shaft 19 on which a selector fork is mounted. A switch 5 is provided for disconnecting the driving wheels for use when the vehicle is stationary and is required to power ancillary equipment. <IMAGE>

Title: Therapeutic rocking apparatus
IPC: A61H1/02
Filed: 1981-02-06
Abstract: Therapeutic apparatus (10) (Figure 1) for stimulating motor responses in a brain-damaged patient consists of a platform (15) adopted to form a seat mounted on a support column (14) by way of a universal joint, such as a gimbal arrangement (16) so that it can be rocked about at least two (orthogonal) mounting axes in the plane of the platform by orthogonally disposed actuators 21 in the form of rods 24 (one only shown) reciprocated by piston and cylinder arrangements. The rods are coupled to the platform by universal joints (26) located on the mounting axes so that each actuator is able to rock the platform about the other axis and rotate relative to its own. The rocking motion is determined by an operator which may be a microprocessor programmed to vary the sequence, direction and amplitude of the motion sufficiently randomly for it to be recognisable to the brain but not rejected as too repetitive. <IMAGE>

Title: A process for the continuous production of an epoxide resin
IPC: C08G59/06
Filed: 1982-03-08
Abstract: The production of epoxide resin with an epoxide equivalent of 180 to 1100 and a diglycidyl ether content of 75 to 85% by weight by the reaction of epichlorohydrin and 2,2-bis-(4- hydroxyphenyl)-propane (diane) in the presence of alkali and water is carried out by a method in which the components of the reaction mixture are continuously brought together in a first reactor, in rotatory and turbulent motion with a rotation speed of 8 to 12 m/sec, and reaction effected with a time of dwell of 1 to 1.5 sec. The reaction is then continued in 2 or 3 further reactors with the same time of dwell in each. The temperature of the exothermal reaction is initially 40 to 110 DEG C and reaches 90 to 150 DEG C. During the reaction an organic solvent may be present. The process provides a high volumetric yield per unit time, the plant for performing the process only requiring a moderate amount of space and a high degree of reaction being obtained, this being indicated by the relatively high diglycidyl ether content.

IPC: C08F4/62
Filed: 1982-03-16
Abstract: A halide of a metal is contacted at a temperature of at least 150 DEG C with at least one metal which is more electro-positive than the metal which is present in the metal halide. The contacting may be effected in the presence of an inert material such as an inorganic oxide or carbon. The metal halide may be zinc chloride or cadmium chloride. The more electro-positive metal may be a transition metal such as titanium or vanadium or a non-transition metal such as magnesium or aluminium, or a mixture.

Title: Dust removal apparatus and method
Inventor: LIVERSIDGE BARRY PETER
IPC: B65G69/18
Filed: 1983-07-07
Abstract: Apparatus for controlling pollution when handling bulk cargoes of pulverulent material comprises a frame 60 supporting a body 12 which defines an aperture 13 through which the bulk cargo is loaded into a container 66 of a vehicle 65. Air currents are generated by a fan unit drawing air into a duct 64 adjacent the aperture 13, which air currents flow both downwardly through the aperture 13 and horizontally immediately beneath the aperture so as to create an air curtain. Dust entrained in rising air currents, produced as a load is deposited through the aperture in the container 66, are deflected by the air curtain and drawn into the duct 64 leading to a filtration assembly 63, in which the dust is separated from the air flow. Screens (15, 16 & 61) depend from the body 12 around three sides of the aperture 13, to effect a seal to the vehicle container 66, thereby to ensure the air curtain extends across the aperture 13, towards the duct 64. <IMAGE>

Abstract: A buffer primarily but not exclusively intended for installations in parking areas for motor vehicles comprises a forward limb (11), a rearward limb (13) and a further limb (22), the forward limb may be provided with a spacer member (17). When subjected to impact, the forward limb (11) tends to move rearwardly and downwardly, the rearward limb (13) is contacted by a spacer member (17) to assist in providing a restoring force to the rearward limb and the further limb (22) provides a restoring force tending to restrict downwards movement of the forward limb (11). The forward limb (11), rearward limb (13) and further limb (22) are preferably made from spring steel and the arrangement enables a buffer to be made which is small in size but which is capable of resiliently resisting severe impact. A plurality of such buffers may be interconnected by an elongate member 30 to form a barrier. <IMAGE>
