Patent FR-2361650-A1 (FR)
Title: Lactate enzymatic determination - by reacting with nicotinamide adenine dinucleotide in the presence of lactate dehydrogenase
IPC: C12Q1/32
Filed: 1976-08-10
Abstract: Quantitative determination of L-lactate involves reacting with nicotinamide-adenine-dinucleotide (NAD) in the presence of lactate dehydrogenase (LDH) to form reduced nicotinamide-adenine-dinucleotide (NADH) and pyruvate. The latter is reacted with glutamate in the presence of glutamate-pyruvate transaminase (GPT) in alkaline buffered solution to form alanine and alpha-keto-glutarate. The NADH formed is measured. The novel feature is that the reaction is carried out in the presence of at least 0.1 M (bi)carbonate. The new reagent contains LDH, GPT, NAD, glutamate, and 0.45-0.60 mol/1. carbonate buffer pH 9.5-10.5. Determination of blood, serum or plasma lactate is important in the stabilization and therapeutic control of diabetics. Elevated serum L-lactate levels also occur in shock, myocardial infarct, uraemia, leukaemia and liver cirrhosis. L-Lactate determination is therefore an important diagnostic tool. (Bi)carbonate ions activate GPT, increasing the rate of removal of pyruvate from the reaction system. This shifts the equilibrium of the initial reaction and considerably reduces reaction time. The result is that lactate determinations can be carried out in 10 mins. or less. Results obtained with the procedure are accurate and reproducible. Additionally, the amount of relatively expensive GPT used can be reduced to 2-4 per ml.

Title: Guide roll track for continuous casting plant - where rolls are prestressed by adjustable compression springs
Inventor: PIETRYKA JOSEPH
IPC: B22D11/128
Filed: 1976-10-11
Abstract: Guide and support roll track for a continuously cast ingot or slab, involves using two rows of rolls mounted in pairs on a frame. The frame is fitted with guides in which the chocks carrying one pair or rolls can slide at 90 degrees to the longitudinal direction (1) of travel of the slab. The two chocks of one roll in each pair are forced towards the chocks for the other roll by a prestressed coil spring; a hydraulic cylinder (HC) is located coaxially w.r.t. each spring, and is used to separate the chocks. In one pref. design, the piston rod of the HC is attached to a chock; and the end cap of the HC forms a thrust surface for the spring; in another design, the HC is located inside the spring; and the HC pref. adjusts the prestressing force applied to the spring.

Patent FR-2367891-A1 (FR)
Title: Cylinder lock for vehicles, buildings, furniture - has adjustable locked cams allowing alteration to accept alternative keys while preventing opening with skeleton key
IPC: E05B29/00
Filed: 1976-10-14
Abstract: The simple cylinder lock has a facility for instant adjustment without tools to accept alternative keys. The lock cannot be opened with a skeleton key. The cams (50) moving in slots in the cylinder (12) engage in cavities (52, 54) and are actuated by key followers (70). Rotation of the cylinder so that the key follower retaining piece (42) moves into the recess (46) releases the serrations connecting the cams (50) to the followers (70). In this setting insertion of an alternative key results in relative movement of cams (50) and followers (70) to conform to the code of the new key. Prevention of opening with a skeleton key is achieved by locking of the cams (50), affected by displacement of the rod (16) from its groove (18) by any small rotational movement.
