Title: Fastener for hollow metal handles of saucepans - comprised detent in hollow cavity engaging with similar connector on pan
Inventor: TEES PETER ING GRAD
IPC: A47J45/07
Filed: 1975-01-15
Abstract: The hollow metal handle (9) is fastened to the enamelled saucepan by a retaining member attached to the side wall of the pan and has locking elements which detachably engage with locking elements provided in the cavity of the handle. Each retaining member can consist of a holding plate (3) fastened to the side of wall of the metal pan and tapers towards its free end. There retaining plate has a detent recess (8) in which engages the detent member of the connection in the cavity (13) of the handle (9). This connecting member is resilient and yields under the effect of the retaining plate when the latter is inserted in the cavity. The pan and handle can be enamelled separately so that different pans can be used with different handles.

Title: Lactate enzymatic determination - by reacting with nicotinamide adenine dinucleotide in the presence of lactate dehydrogenase
Inventor: BERNT ERICH
IPC: C12Q1/32
Filed: 1975-02-12
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.

The use of force to open any of the gates whilst the mechanism is not free, as attempted by a bank robber for example, will set off an alarm device. The alarm trigger mechanism includes an electrical switch operated by a spring arm contact device.

Title: Tumbler-action car window operator - has spur and ring gears mounted on eccentric disc on handle shaft
Inventor: SPILLER RUDOLF
IPC: E05F11/44
Filed: 1975-12-11
Abstract: The vehicle door has a window-lifting mechanism which consists of an ordinary spur gear fixed to the door panel (1), and meshing with a ring gear (4) rigidly fitted to the operating handle (7). The handle shaft (5) is fitted with an eccentric disc (6) on one end, and with a handle (7) on the other end. The tumbler operation of the ring gear (2) due to the eccentric disc (6) is caused by rotating the arm (3). Because meshing of the two gears takes place at different locations in various positions of the window, and because several teeth are in mesh at any time, the mechanism presents a self locking gear assembly, so that no additional brake device to keep the window in position, is required.

Title: Heat exchanger for hot corrosive gases - in which thermal stresses are avoided by supplementary cooling elements on shell (NL070976)
IPC: F28F9/02
Filed: 1976-03-04
Abstract: Heat exchanger for corrosive gases consits of tube plates with tubes extending between them and surrounded by a shell which forms part of a duct through which the gas is flowing. The hot gas flows through the tubes with the cooler medium in the shell. The duct walls close to the exchanger and the shell have channels attached to them through which a second cooling fluid can be passed. This extends into the duct either side and round the branches for the cooler medium. Both tube plates are mounted by means of an expansion element in the wall. This consists of a curved circular body of relatively thin material, one edge being joined to the tube plate, the other to the duct wall. The exchanger is useful with very corrosive media where expensive and exotic alloys are necessary. These units are normally constructed cold and under the operating temps. envisaged, become subject to thermal stresses.: At joints and welds, these become areas of corrosion potential. The system described maintains the metal at relatively low temp. thus avoiding thermal stressing and associated stress corrosion.
