Patent FR-2233952-A1 (FR)
Title: Trousers braces invisible when being worn - pass round the shoulders and are fixed to the side of trousers
IPC: A41F3/00
Filed: 1973-06-25
Abstract: Instead of, like in the present models, being fixed to the front and back of the trouser waistline pleat, which makes them unpleasantly visible when the user has no waistcoat or pullover on, this type of trouser-suspenders has its two sections connected together, forming a loop. It may be a single or a double loop, the front part of which passes in front of the shoulder in its external zone, and slides along the body, connecting with the opposite side on the back of the opposite loop. A clasp is fixed to the side of the trousers and is hidden from view.

Title: Double-acting ram braking system - uses long needle valve parallel to axis ram
IPC: F15B15/22
Filed: 1973-10-31
Abstract: The system operates at the end of the ram stroke, having a long shut-off needle valve, which runs parallel to the axial direction of the ram. It can be set against the surface of the orifice to be sealed, and the deflection of the surface of the orifice is used to determine the size of the opening. Compared with the conventional method using short needle valves at right angles to the ram axis, the system has the advantage that self-centering effect is more easily achieved, without making the braking effect come on suddenly.

This contacts the ski (7) to soften and remove deposits as it is pushed (B) over the roller which rotates in the opposite sense (A). A third roller (19) is used for drying and a fourth (12) on the entry side supports and guides the ski using a rib projecting into the central longitudinal groove underneath the ski.
Patent FR-2276447-A1 (FR)
Title: Mounting discs inside barrel locks - easily accomplished by having interlocking shoulders inside barrel and on disc
IPC: E05B29/00
Filed: 1974-06-26
Abstract: A mounting for the discs inside a barrel lock is an improvement on the conventional mounting method. The discs (4) slide into transverse slits in the barrel which also contains springs lodged inside cylinders. The springs hold the discs in the locked position when the key is withdrawn. The body of the barrel has, in each of the slits a shoulder (6) and the discs which are activated by the key have, on the marginal side, without a rib (5) a shoulder (8). The shoulders (6, 8) act together to ensure the locking of the disc once it has been introduced far enough into the barrel by means of the spring. Using this method the discs are easily and quickly placed in position inside the barrel.

Title: Sterilising water for swimming baths - using two parallel constant delivery pumps to inject measured doses of microbicide soln.
IPC: C02F1/76
Filed: 1976-05-31
Abstract: A process and a plant installation are for sterilising the water supply of a swimming pool etc. by introducing an aq. soln. of a microbicide, the dose of soln. being automatically adjusted to suit the requirements of the water. A first fraction of the dose is pumped continuously into the water supply while the second, balancing fraction of the dose is pumped in intermittently. Both dosing pumps are pref. of the constant delivery type. The continuously pumped fraction is pref. limited to a level which just maintains adequate sterilisation when no swimmers are using the pool. When the higher doses are necessary an automatic analyser starts up the intermittent pump which is pref. stopped by a timer. A pH analyser and timer are pref. employed in conjunction with a further, constant delivery pump inserting a soln to maintain pH of pool water at 7-8. Used for sterilising the water of swimming pools to prevent transmission of germs. Ensuring that the level of microbicide additives is not sufficient to make the water unpleasant. Variable delivery dosing pumps are replaced with constant delivery pumps which are cheaper, more robust and reliable.
