Patent GB-2173854-A (GB)
Title: Door operating mechanisms
Inventor: PERRY JOHN LAWRENCE
IPC: E05F15/10
Filed: 1986-04-11
Abstract: An operating mechanism for a vehicle door has a power actuator (22, 24) acting through a rotary clutch mechanism comprising coaxial rotary members (34, 42) which are urged together by a spring (38) so that engagement elements (44, 46) transmit the actuator torque to operate the door. The engagement elements comprise inclined surfaces which, if a sufficient torque is applied, allow the two members to separate against the spring force and to rotate relative to each other. In the event of malfunction of the power actuator, therefore, manual pressure can be applied to the door to open it. Re-engagement of the rotary members occurs when the engagement elements are returned to their position of engagement. <IMAGE>

Title: Mechanically actuatable sliding-caliper disc brake
Inventor: RUPPRECHT BERND
IPC: F16D65/14
Filed: 1989-04-17
Abstract: The mechanically actuatable means for moving the sliding caliper (1, 4, 5) relative to the brake disc (6) consists of oblique-track spreading means (10, 11, 12) operated by an actuating shaft (7). Automatic adjustment of the clearance is effected by means of adjusting nut (14) which is coupled to the actuating shaft (7) through a rotational ratchet mechanism (52, 53) which is operative when the actuating shaft (7) is turned in the brake actuating direction. This rotational ratchet mechanism is formed as saw-tooth ratchet and structural arrangements are made so that when the actuating shaft (7) exceeds a certain torque one section of the coupling can yield axially against the force of a precompressed spring (23) so that no further clearance adjustment is made. This prevents overadjustment and consequent overheating of the brake when large actuating forces are applied. …<IMAGE>…

Title: Simulating non-homogeneous fog with a plurality of translucent layers
Inventor: OLIVE GRAHAM JOHN
IPC: G06T15/10
Filed: 1991-04-22
Abstract: Image data is derived from a model for each of an array of sampling points distributed across screen space. A non-homogeneous fog structure is defined in world space coordinates as a series of up to 1024 parallel strata 35 of predetermined extinction coefficient. The positions of the eyepoint E and a feature to be displayed relative to the fog structure are determined. The distance from the feature to the eyepoint is calculated. An average value of the extinction coefficient between the eyepoint and the feature is calculated from the defined parallel strata, and the attributes of the feature are modulated as a function of the calculated distance and the calculated average value of the extinction coefficient. This gives a more realistic simulation of patchy fog, fog banks or moving through fog. <IMAGE>
