Title: Colour video test signal generation
Inventor: LATSHAW DON
IPC: H04N17/02
Filed: 1990-06-11
Abstract: A digital colour video test signal is produced from stored component signals Y, U, V corresponding to a single line only. As shown, the components are PAL encoded 20 at a rate which is an integral multiple of line rate. Since the frame offset in the subcarrier frequency means that the same line to subcarrier relation only recurs four times per frame, i.e. every 157 lines, the encoded signal 22 is interpolated at 24 using coefficients stored at 30 for each of the set of 157 lines, each interpolation using eight products of sample and coefficient. The interpolated signal 32 is stored at 34 and sampled at a subcarrier related rate to produce a PAL D2 test signal 40. The system shown may form part of a larger system (Fig 2) providing a choice between PAL D2, NTSC D2, a D1 signal or a non-interpolated PAL D2 signal, so that, for example, interpolated and non-interpolated PAL D2 signals may be compared at a selected vertical position to assess or modify the interpolation coefficients.   <IMAGE>

Title: Monitoring blood pressure
Inventor: ECKERLE JOSEPH S
IPC: G06F17/00
Filed: 1991-02-28
Abstract: Intraarterial blood pressure is measured noninvasively by an electromechanical transducer (22) having an array of transducer elements which are located across an artery (24) with the end elements extending beyond opposite edges of the artery. A set of diastolic and/or systolic pressure and pulse amplitude values is obtained from the transducer elements and stored in a computer (62). A transducer element located substantially at the center of the artery is identified by calculating the center of gravity of the pulse amplitude distribution, by identifying the mid position between two peaks in the distribution, or by locating the peak of a polynomial fitted to the distribution. The blood pressure values from this central element are taken as the true values. <IMAGE>

Title: Hardened titanium nitride coated insert and brake shoe for backstopping clutch
Inventor: OSTRANDER ROBERT J
IPC: C23C14/06
Filed: 1991-04-30
Abstract: A hardened brake shoe insert 28 for use in bi-directional backstopping clutches is formed from a base material of high speed alloy tool steel, which is relatively inexpensive and easy to machine. The base material is formed into the desired shape for the insert 28, then hardened and tempered to achieve a desired hardness. Then, a coating of titanium nitride is applied to the insert by a physical vapor deposition process or a chemical vapor deposition process. The titanium nitride coating provides a very hard surface to the insert, which permits the insert to be used in the backstopping clutch. In an alternative embodiment, the brake shoe 15, 16 itself is formed in the manner described above, and no inserts are used in the clutch. The base material may have a hardness within the range of 62-65 on the Rockwell C scale and the titanium nitride coating may have a hardness of approximately 85 on the Rockwell C scale. <IMAGE>

Title: Determining the relative position of semiconductor water patterns
Inventor: CHILDS RUSSELL
IPC: H01L23/544
Filed: 1991-06-25
Abstract: To determine the position of a mask pattern formed on a surface of a semiconductor wafer (1) relative to the position of a reference pattern previously formed on the surface, a photosensitive film (8) is applied to the surface, and areas of the film are selectively irradiated with light via a photo mask to form a latent image of the mask pattern of exposed and unexposed areas of film. The reference and mask patterns include diffracting portion (4) and (5) respectively. Relative movement is effected between the wafer and a laser beam (6) so that the diffracting portions (4) and (5) of the reference and mask patterns are successively irradiated by the beam. Laser light is diffracted by the reference portion (4) and also by the mask portion (5) due to the difference between the indices of refraction of the exposed and unexposed parts of the latent image prior to development thereof. The spacing between the resulting diffraction patterns is measured to determine the spacing (x) between the reference and mask patterns. <IMAGE>

Title: Apparatus for generating graphics
Inventor: CHANEY JOHN WILLIAM
IPC: G09G5/00
Filed: 1992-10-26
Abstract: A color interpolation circuit (360) allows information uniquely identifying one of six colors to be stored by using only two binary bits of memory storage, or one of 120 colors using only four binary bits of memory storage. Normally N bits can uniquely designate 2<N> (standard) colors, but by reserving one bit pattern for an interpolate command, code, which causes the production of colors 30 intermediate that of two standard codes, a further 2<N> - 1 C2 colors can be designated. For two bits three intermediate colors are added to the three remaining standard colors and for four bits the 15 remaining standard colors are augmented by 105 intermediate colors. When displaying text the three standard colors may be the (red) background (110), the (white) foreground (100) and the (black) edge (120), the intermediate colors then being grey (black/white) (130) and dark red (red/black) (140), with pink (red/white) also being available. <IMAGE>

Title: Retractable Injector Carrier Assembly
Inventor: HARGREAVES PAUL DAVID
IPC: G05D11/00
Filed: 1994-07-07
Abstract: Chemical dosing injectors are used extensively to inject liquid or gaseous mediums into process streams and treatment applications in chemical manufacturing processes, e.g. water treatment plants for potable water, swimming pools, process streams involving chlorination, bromination, ozone injection or general chemical injection. Current injection methods are prone to the build up of deposits at the injector outlet and within the injector body assembly. The injector assembly incorporates a unique bluff body shape (1) which causes vortices to be generated at the interface with process medium thus greatly increasing mixing in the injection zone (2). Chemicals are injected via four slots close to the vortex shedder (3). The injection spindle can be cleaned without the need to shut the process down. An indicator line (7) on the inner spindle appears when fully retracted and closed off, thus allowing rodding or brushing to be carried out on the internal structure of the inner injection spindle (5). <IMAGE>
