Title: Mounting for a telescopic sight
Inventor: HUTCHISON ROY
IPC: F41G1/387
Filed: 1982-11-05
Abstract: A mounting for securing a telescopic sight to an air rifle comprises two longitudinally spaced holding rings, the lower parts of which are attached to one of a pair of bars (1, 2) extending parallel to the rifle cylinder. As the bars are brought together by screws (10), they clear the top of the cylinder by reason of upper rectangular rebates (3a, 4a) at the lower inside edge of each bar, while lower V-shaped rebates (3b, 4b) cooperate with the lower surfaces of the bars to form sharp edges which bite into the grooves of a dovetail (not shown) on the top of the cylinder. The mounting is thus adjustable to fit different sizes of dovetail. Shim washers (9) between the bar (2) and the legs of the holding rings serve to centre the sight on the rifle cylinder and compensate should the barrel be slightly bent. It is possible to adjust the angle at which the sharp edges of the bars bite into the grooves of the dovetail to provide a strong clamping action. <IMAGE>

Title: A method for enzyme liberation from bacterial cells
Inventor: BREEZE DR ANTHONY STUART
IPC: C12N1/06
Filed: 1983-03-31
Abstract: The use of a temperature sensitive prophage to procure the lysis of bacterial cells increases the yield of protein available by avoiding the use of harsh or vigorous physical and chemical treatments and by causing the lysis of all the cells in the culture. The lytic process is induced by raising the temperature of the culture to a point at which the prophage becomes unstable but which still allows bacterial metabolism to continue. The method can be applied not only to batch grown cells but also to cells grown in continuous culture.
