Title: Toilet water supply system
Inventor: OSBORNE NIGEL PETER
IPC: E03B1/04
Filed: 1991-04-22
Abstract: A toilet water supply system which replaces the existing mains water supply to the toilet cistern with domestic recoverable waste water resulting in overall reduction of domestic consumption and more efficient use of pure water. This is achieved by collecting waste water from recoverable sources through pipework (1) to a filtration unit (2), which removes large particles for the waste water. A facility is provided with the filtration unit (2) to enable the filter to be cleaned. The filtered water passes into a storage tank (3) which holds the water until needed. From the tank (2) the water is drawn by a pump (5) controlled by pressure switch (6) assisted by an accumulator (7) and delivered to a device (8) which will scent and colour the water prior to entry into a conventional toilet cistern. <IMAGE>

Patent GB-2256692-A (GB)
Title: Gear casing having walls of sinuous cross-section
Inventor: MORELLI PETER ALAN
IPC: F16H57/02
Filed: 1991-06-11
Abstract: Gear units almost invariably have a casing containing a body of oil for both lubricating and cooling purposes. The casing has walls which are generally plane internally and generally ribbed externally, and a fan has been provided for assisting the removal from the ribs of unwanted heat generated by the gearing and transmitted through the oil to the casing. To remove the need for a fan the casing is made with walls of sinuous cross-section and substantially constant thickness. Thus, the maximum practicable area of the interior makes contact with the oil to abstract the heat therefrom, and furthermore the heat then has to travel the minimal practicable distance through the walls to reach the outside air which makes contact with the maximum practicable area of the exterior. The walls have internal ribs to provide additional strength, and the casing is a casing with integral ribs. The casing has an attached electric motor, and is particularly useful for worm gear reduction units and gear units with helical first stage gearing and worm second stage gearing. <IMAGE>

Title: Focusing and exposing mechanism for cameras
Inventor: HUANG TSAI-JEON
IPC: G03B17/42
Filed: 1991-11-19
Abstract: An improved mechanism for cameras includes a solenoid which rotates a cam ring (2) to a control position for focusing or exposing; and a motor which drives a planetary gear set (40) including a swing arm (6) with a pinion (7) fixed thereon. When the cam ring (2) is in the control position for focusing, the pinion (7) transmits the power generated by the motor to the teeth (3a) of a focusing ring (3) to cause the focusing ring (3) to rotate and focus. When the cam ring (2) is in the control position for exposing, the pinion (7) disengages from the teeth (3a) of the focusing ring (3) to engage with the internal gear (8) of the planetary gear set (40) to cause the swing arm (6) to oscillate and thereby actuate the shutter. At this time, the cam ring (2) also initiates the movement of a ratchet set (90) so that the focusing ring (3) cannot freely move during the exposure process. <IMAGE>
