Title: Supercharged four stroke piston engine - has flap valve in charging turbine outlet and responsive to exhaust pressure
IPC: F02B75/02
Filed: 1974-09-23
Abstract: The turbocharger turbine (9) is driven from the engine exhaust gases which are allowed to impinge upon the turbine (9) which is carried in a turbine casing (8). An outlet valve (2) is located in a tube (1) coaxially located in the discharge of the turbine. The valve is connected by a spindle (5) to a crank (6). The crank is linked to a spring (3) and to a piston (4). The spring (3) acts to close the valve (2) and the piston (4) acts to open the valve. The piston (4) is connected to the gas intake by a passage (7). A decrease in exhaust pressure closes the valve, allowing pressure increase in the turbine. The system evens out engine operation.

Title: General use support element - is for building bridge prefabricated elements with metal bar stirrup and longitudinal bars fitted together
Inventor: BLANPAIN JACQUES
IPC: E04C5/18
Filed: 1974-10-17
Abstract: The metal support element is for trellis type construction made of longitudinal bars fixed to trapezoidal shaped stirrups. The lateral branches support lower longitudinal bars. Each stirrup branch is sloped at 6 deg. to the vertical. The cross sectional area of the longitudinal bars can be less than, equal to, or more than the material from which the stirrups are made. The distance between the longitudinal bars fixed to the stirrup branches and the ends of these branches is a multiple of the diameter of the longitudinal bars. This construction avoids many of the difficulties met with the more normal types of fixings.
Patent FR-2251860-A1 (FR)
IPC: F16H61/08
Filed: 1974-10-24
Abstract: A shift control mechanism is provided for a multiple-forward-speed manual transmission which controls operation of the shift lever between the reverse drive position and one forward drive position to prevent inadvertent shifting which might damage the transmission. A transmission lever whose movement is controlled through the shift lever is formed with a projection extending therefrom which is adapted to engage a movable pin mounted in a housing. The housing is axially movable along a guide shaft and the pin is movable between an extended and a retracted position relative to the housing. The erroneous shifting operation between the reverse drive position and the one forward drive position is prevented by engagement between the projection and the pin in a manner which does not interfere with appropriate shifting of the transmission during vehicle operation.

Title: Rider propelled vehicle for e.g. children - operated in forward or reverse, by swingable front wheel assembly
IPC: A63G19/00
Filed: 1975-01-29

Title: High temp. liq. metal flow measurement - for use in extraction or refining processes
IPC: G01F1/58
Filed: 1975-02-13
Abstract: A process and device are descrived for measuring the flow of liq. metal at high temp. by measuring the rate of flow and the cross-sectional area of the stream of metal. An electromagnetic flow meter is employed and is situated in the channel through which the metal flows so that the measuring component of the flow meter is filled over its entire cross-section. The channel may be vertical with the metal flow from bottom to top or horizontal or with a slight slope in the latter two cases the measuring component is placed at the lowest point of a syphon. The measuring component is a cylindrical channel consisting of a refractory material with good resistance to erosion by the metal flow and which is a poor electrical conductor and is non-magnetic. The electrodes are made of a material resistant to erosion by the metal but which are good electrical conductors. The wear of the tube is uniform and its cross-section remains circular. The measuring apparatus takes into account the increases in the cross-section of the channel by a correction which consists of periodically interrupting the supply to the coils creating the magnetic field and applying a p.d. of value, E1 to the electrodes. This p.d. produces a current of intensity I which is measured at the start, the distance between the electrodes being d. During the operation the current I' corresponding to the electrode distance d' is measured periodically and the e.m.f. induced by the field B, is corrected according to the ratio I/I'. The measurement of the flow of a liq. metal is useful in extraction and refining processes and allows control and automisation of these processes. In process in which a liq. metal is used as a heat carrier the amt. of heat been conveyed can be determined from the measurement of the flow.

IPC: A23C19/05
Filed: 1975-06-25
Abstract: Coagulation of proteins and their derivs. in milk with the use of proteolytically coagulating enzymes is improved in that the enzymes are added to the milk in two steps. In the first step, the enzymes are added in an amt. which does not cause any coagulation of the casein; in particular 20-50 mg. of enzymes having a coagulating activity of 1:4000 to 1:100000 are added to 100 l. of milk (temp. 0-32 degrees C; acidity 6.0-8.5 degrees SH). In the second step, the remainder of the enzymes is added, in particular 50-1000 mg having a coagulating activity of 1-100000 (temp. 20-45 degrees C; acidity 7.0-12.5 degrees SH). The enzymes can be of animal, vegetable, microbial or fungal origin. The consumption of rennet or its substitutes during the prodn. of hard, soft and cottage cheese, is reduced by at least 66%.

Title: Seal ring with resilient sealing lip - having differential coefft of expansion to reduce seal pressure on heating
IPC: F16J15/3284
Filed: 1975-07-23
Abstract: Sealing ring has a resilient lip for engaging a slide surface, wherein the lip is made of at least two layers of material of which the layer (6) facing the slide surface (8) has a greater coefft. of thermal expansion than the layer or layers (4) remote from said surface. The lip is supported in relation to the surface by a ring secured e.g. to a shaft (2). Should the temperature of the seal rise unduly e.g. by lack of lubrication, the unequal expansion of the layers results in a reduction of seal pressure and the possibility of damage to the seal seal is reduced.
