  • Bases for showers
    Patent number: 4091477
    Abstract: A known type of base for a shower comprises a carrier having a shower tray. The carrier can be moved between a first position and a second position. In the first position the shower tray is substantially horizontal and can thus be used in taking a shower. In the second position the shower tray is substantially vertical and the carrier thus occupies less floor space. The improvement characteristic of the invention is the provision of a wash basin as part of the carrier; the basin opens upwards for use in washing when the carrier is in its second position.

  • Load sensitive brake control valve assemblies
    Patent number: 4090740
    Abstract: A control valve assembly for a vehicle braking system comprises a control valve having a control valve operating member operable to control communication between an inlet and an outlet, a pivoted lever arrangement subjected to an input force applied by a spring and applying an output force to the valve operating member, and a device for varying the lever ratio of lever arrangement in dependence upon vehicle loading. The input force applied to the lever arrangement by the spring is substantially constant and independent of vehicle loading, variations in the lever ratio varying the load transmitted to the valve operating member.

  • Transit capsules
    Patent number: 4090366
    Abstract: A transit capsule for providing operator access to a sub-sea installation part in a capsule on a sea-bed, the two capsules having complementary means to form a conjunction capsule, has means selectively connecting an expansion vessel in the transit capsule to the other two capsules; on connecting the said other two capsules which are water-filled, their pressures are reduced to the atmospheric pressure in the transit capsule with only a small amount of water being ejected to balance the pressure and this small amount can be inspected to determine the state of the said other two capsules by suitable inspection means.

  • Fluid valve assemblies
    Patent number: 4090533
    Abstract: In a power control valve assembly in which the position of an inlet valve member relative to its seat is controlled by a control rod extending through a passage terminating in the seat, an end portion of the control rod has a profile which gives a variable throttling of flow through the passage in dependence upon the axial position of the control rod. In the valve described the end portion of the rod has an end part of constant diameter connected to a further part of reduced diameter by a sloping shoulder. Two such valve assemblies are shown arranged in parallel and operated through a single resilient block and a balance beam.

  • Automatic slack adjusters for vehicle brakes
    Patent number: 4085830
    Abstract: In an automatic slack adjuster for a vehicle brake, an adjuster member acts on a part of an adjustable strut assembly for maintaining a substantially constant braking clearance between a braking member and a rotatable braking surface, the adjuster member acting on the part through a driven ring, and an overload spring urges a clutch face on the driven ring into engagement with a complementary clutch face on the part so that the driven ring and the part are movable together unless the reaction between the clutch faces exceeds the loading of the overload spring whereafter the driven ring can rotate relative to the strut assembly to preclude adjustment.

  • Disc brakes and mounting structure therefor
    Patent number: RE29582
    Abstract: The invention concerns disc brakes of the kind in which only one of the friction elements is directly moved into engagement with the brake disc or other rotor, the other friction element being displaced as a result of reaction forces set up by such engagement and for this purpose being carried by a caliper member which is slidable responsive to such reaction forces. In a disc brake of this type in accordance with the present invention, the caliper is mounted for sliding movement on a first pin arranged between the caliper member and a fixed torque plate member adjoining the brake disc, rotation of the caliper member about said first pin being restrained by a second pin secured to one of said members in circumferentially spaced relation with said first pin.
