Patent GB-2260868-A (GB)
Title: Recharger for dry cells and dry cell batteries
Inventor: COLES BARRY JOHN
IPC: H02J7/02
Filed: 1992-10-22
Abstract: The recharger comprises an A.C. source 10 connected to the dry cell or cells via a current control circuit 11 having parallel paths 14, 15 with oppositely directed diodes D1, D2 in series with respective transistorised trigger-operated back-to-back voltage follower circuits 12, 13. The resistor values in circuits 12, 13 are chosen so that for fully discharged cells the ratio of the reverse current to the forward, charging. current is 1:5, and this ratio approaches 1:1 as the cells become substantially fully charged so that the net d.c. component is then substantially zero. The reverse current path 15 is conductive for longer than the forward path 14 during each A.C. cycle, the circuit 13 effectively establishing an approximately constant reference current value corresponding to the value to which the forward, charging, current asyntopically declines. <IMAGE>

Title: Drilling Machine
Inventor: RIXHAM NICHOLAS ANDREW
IPC: B23B45/14
Filed: 1996-03-15
Abstract: A portable drilling machine comprises an electromagnetic base 12 from which a column 14 extends perpendicularly. An electric power drill 16 is slidably disposed on the column 14 by means of a slide 18 .

Title: Method for determining false negative results in an immunoassay
Inventor: CHILDERSTONE MICHAEL STEVEN
IPC: G01N33/543
Filed: 1996-08-02
Abstract: There is disclosed a solution comprising the dye 5', 5''-dibromo-O-cresolsulphonephthalein which can be used as a dilution buffer in an assay. The presence of the dye with the assay reagents monitors whether the sample of biological fluid e.g. plasma or serum, has contacted the assay reagents. The dye reacts with albumin in the biological fluid to produce a colour change. This method prevents false negatives readings due to the failure of a specimen to be entered into an assay. The dilution buffer comprises a blocking agent such as gelatin, globulin or casein which does not prevent a discernible change in light absorption by the dye nor obscure the change in colour.
