Title: Walking stick with grapple device
Inventor: HORSTMANN BEVAN GRAHAM
IPC: A45B3/00
Filed: 1988-09-22
Abstract: A walking stick with a grapple device comprises a stick having grapple arms 4 pivoted to a lower region. A lever assembly for activating the arms extends to an upper region of the stick and is coupled there to a pair of vertically spaced operating levers 16, 17 which are pivoted to the stick. Pivoting of the upper operating lever 17 down towards the lower operating lever 16 displaces a first lever linkage 11 to urge closing of the arms 4; pivoting of the lower operating lever 16 displaces a second lever linkage 28 downwards and this acts to displace the first lever linkage 11 to close the arms 4. The arrangement is such that when the lower operating lever 16 is in a lowered position it and the second lever linkage 28 constitute a toggle linkage such that raising the lower lever 16 urges opening of the arms 4 with a substantial mechanical advantage. Thus, the arms 4 of the grapple device may be opened and closed by a small force applied to the lower lever 16 and can be easily opened by a disabled operator even if they have become muddied and stuck together. <IMAGE>

Title: Bonding brake linings
Inventor: IWATA YUKIO
IPC: B23P15/18
Filed: 1988-10-19
Abstract: A brake lining bonding apparatus in which brake linings 11 positioned between a loop-like pressure-imposing band 17 and a pair of brake shoes 12 disposed on opposite locations at the inner side of the band are pressure-bonded to the brake shoes by expanding in opposite direction the expand member which is urged by springs 3. The pressure-imposing band is provided with rigid strips 16 at two circumferential locations for positioning itself in a predetermined position and is formed in substantially eliptic shape. The expand member is arranged not to engage either side of the brake shoe rib but merely abuts the ends 12(a), 12(b) of a shoe. Such an arrangement facilitates loading and unloading of the shoes and automation of the process. The apparatus is mounted on skates 10 which enable it to be slid through an automated process irrespective of the width of the linings. Holes 18 are provided in band 17 through which members may pass to engage the circumferential ends of the linings to position them for bonding. …<IMAGE>…

Title: Enhanced chemiluminescent assay
Inventor: KRICKA LARRY JAN
IPC: C12Q1/42
Filed: 1990-10-16
Abstract: An enhanced chemiluminescent assay, in which a dihydropthalazinedione such as luminol, a peroxidase such as HRP and an oxidant such as H2O2 are co-reacted in the presence of an enhancer such as p-iodophenol, is modified. The enhancer is generated by enzyme-catalysed reaction of a pro-enhancer, e.g. cleavage of p-iodiphenol phosphate by alkaline phosphatase, enabling this enzyme to be assayed instead of peroxidase. Alternatively, the enhancer is added, an anti-enhancer such as p-nitrophenol is generated by enzymatic reaction of a pro-anti-enhancer such as p-nitrophenol phosphate and the reduction in luminescent emission is measured.

Filed: 1992-07-30
Abstract: A video luminance signal is digitized by an analogue- to-digital-converter (ADC1) and fed to "signal separators" (111, ..., 113) which gate the luminance signal so that only selected regions of an image are processed. The gated signals are weighted (121, 122, 123) and combined (ADD1). The combined signal is supplied, via band-pass filter bank (300), to a comparator (400) directly and also via a RAM. The RAM functions as a delay. Consequently signals corresponding to different lens positions can be compared. An object in the image may be tracked by means of further comparison of delayed and undelayed versions of the comparison signal. Band pass filters (BPF1, BPF2, ..., BPFm) of filter bank (300) are used starting with the one with the lowest pass frequency. <IMAGE>
