Title: Method of and arrangement for generating a two-dimensional image
IPC: G06T15/40
Filed: 1988-09-20
Abstract: A method of generating a two-dimensional image representing a 
three-dimensional scene is described. The method comprises: 
a) storing a set of foreground pixel data and at least one set of 
background pixel data, each such set defining a colour and a depth 
for each pixel of the image; b) selectively modifying the stored 
foreground and background data in response to a series of input 
pixel data defining colour and depth for a series of pixels of the 
image; and c) forming output pixel data by combining the stored 
foreground and background colour for each pixel in proportions 
defined by a mixing value associated with that pixel. In one 
embodiment, step (b) comprises selectively modifying the stored 
data depending on the input depths so that:  
(i) if the input depth is greater than the stored foreground and 
background depths, the stored foreground and background pixel data 
are left unchanged, (ii) if the input depth lies between the 
stored foreground depth and the stored background depth, the input 
pixel data is stored in place of the background data for that 
pixel, and (iii) if the input depth is less than both the stored 
foreground and background depths, the stored current foreground 
data for that pixel are stored in place of the stored background 
data and the input data are stored in place of the current 
foreground data. An arrangement is described for performing the 
method. The arrangement may form part of an electronic graphics 
system.

Patent EP-0327059-A3 (EP)
Title: Liquid metal processing
IPC: B22D11/10
Filed: 1989-02-01
Abstract: A method of removing heat from molten metal in which the metal is caused to flow freely within a gaseous media or vacuum over a body disposed within the metal stream such that any tendency for the metal to solidify during its passage is effective on the surface of said body against which the solidifying metal contracts into intimate contact herewith. The body may be forcibly cooled e.g. by water. In accordance with this invention since the liquid metal is not enveloped by a channel (7) or pipe the solidifying shell tends to shrink on to the body, no gap is created as hitherto and accordingly much higher heat transfer coefficients between the shell, and thus the liquid metal, and the cooling body are achieved.
Patent EP-0335149-A3 (EP)
Title: Semiconductor memory redundancy scheme
IPC: G11C11/413
Filed: 1989-03-09
Abstract: A semiconductor memory system in which wordline 
redundancy is implemented without impacting the access 
time. A redundant decoder circuit generates a wordline 
drive inhibit signal which inhibits the generation of a 
normal wordline signal. Deselection also deselects the 
normally accessed reference cells, requiring that the 
redundant cells provide their own reference signal. This 
last requirement is accomplished by utilization of twin 
cells for the redundant memory. Placing the redundant 
memory cells on the sense node side of the bit line 
isolators enables the effective doubling of the number of 
redundant cells available for each of a plurality of 
sub-arrays of a normal memory.

Title: Webbing retractor for seat belt locking mechanisms in automotive vehicles
IPC: B60R22/44
Filed: 1989-11-08
Abstract: The webbing rectractor for seat belt locking mechanisms in automotive vehicles is equipped with a comfort function. Connected functionally in series between belt reel (12) and housing (10), via a ratchet wheel (24), are a retracting spring (38) and an auxiliary spring (22) designed to be weaker than the latter. The rotation of this ratchet wheel (24) can be locked selectively by a pawl. The transition between reduced and unreduced tension in the belt webbing is gentle, jerk-free and quiet since the rotation of the ratchet wheel (24) is inhibited by a braking device for as long as the auxiliary spring (22) is not fully tensioned or is at least almost fully tensioned. This braking device comprises lever-like engagement elements (40) which are swivellably mounted on the ratchet wheel and are displaced in the axial direction by the pressure exerted by the outer periphery of the auxiliary spring (22) in order to activate a friction brake.

direction of rotation of the motor 4, and also outputs a 
corresponding signal to the controller 3. An electronic 
switch 6 is controlled by the controller 3 so as to 
control current fed to the motor 4 as to achieve a 
braking effort. The controller 3 senses the deceleration 
rate of the motor 4  via  a current sensor 5. When the 
output signals of the first and second detectors 11 and 
12 indicate that the axial motion of the motor 4 is 
opposite to that selected, the braking effort of the 
motor 4 is so controlled as to maintain deceleration of 
the motor above a predetermined level.
