Patent FR-2250966-A1 (FR)
Title: Supply air inlet for air conditioned room - discharges two parallel horizontal streams of air at high level
IPC: F24F7/06
Filed: 1973-11-08
Abstract: Conditioned air for heating or cooling is delivered from a supply duct in a ceiling space to a discharge outlet at high level in the room. The outlet has two branches one above the other. The lower branch is set to discharge a fixed quantity of air at a constant velocity. This establishes a pattern of air movement which also remains fixed. The upper branch is thermostatically controlled to discharged a quantity of air which varies with the heating or cooling demand of the room. This arrangement enables the total quantity of air to be varied without any change in the pattern of air movement.

Title: Improving milk output of cows - by puerperal feeding with supplementary protein protected against degradation in the rumen
Inventor: SINGER HEINZ
IPC: A23K1/00
Filed: 1976-09-23
Abstract: Method for qualitatively and quantitatively improving milk output in cows involves feeding the cows during the puerperal phase with 150-600 g protein/day in addn. to the usual fodder, the additional protein being administered as a feed supplement in the form of protein cpds. protected against premature degradation in the rumen. The supplementary protein overcomes the protein deficiency experienced by high-yield milk cows during the puerperal phase (10 weeks following calving or onset of lactation) attributed to increased energy requirement at this time accompanied by poor absorption of nutrients. Protection of the protein against degradation by rmen bacteria ensured that all of the administered protein is physiologically available to the cow. The protein content of the milk from cows fed the supplementary protein is up to 15% higher than that of cows given no protein supplement. In addn. the supplementary protein prevents reproduction disorders and other disorders that can otherwise occur with high-yield dairy cattle.

Title: Quay wall for canal wall construction - uses lost coffering in successive layers with reinforcements compacted in two stages
Inventor: PRANDI ERIO
IPC: E02D29/02
Filed: 1977-01-17
Abstract: The technique is for the erection of works under water or in the air, such as quay walls, canal and basin facings or support walls. Sections are laid one above the other, of building material. Between each layer a reinforcement of cross members is and incorporated to a coffering which rises with the structure.

Title: Safety gear for e.g. up=and=over garage door - has secondary counterweight manoeuvred by pulley block and resisting reversal of door movement
IPC: E05F17/00
Filed: 1977-03-29
Abstract: The safety mechanism comprises a counterweight(1) which is manoeuvred by a pulley block and affords absolute safety to potentially dangerous counterbalanced elements, e.g. an up and over garage door. The door may be displaced with the assistance of a prim. counterweight on pulley-guided cables, and the additional counterweight (1) may be fixed to the original. The mechanism stabilizes the leaf of the door in the event of strong winds etc. The action of the additional counterweight increases safety factors and opposes the reversal of a manually effected door movement. The pulley-block(4, 7) compensates for the additional weight(1) and may be operated by a crank-handle(5). The block includes a brake of which the capacity considerably exceeds the forces applied by the weight (1). The brake may retain one of the counterweights should the cable to the prim. counterweight be ruptured.
