Patent FR-2302481-A1 (FR)
Title: Vapour treatment of e.g. textiles uses heat exchanger - to heat up condensate with used vapour passing from treatment process
IPC: F22D1/34
Filed: 1975-02-27
Abstract: Steam treatment is effected in a chamber supplied with steam from a heater. Used steam passes through a heat exchanger to a condensation chamber where it is converted to water. The water is pumped back through the heat exchanger to the heater to produce steam which is fed back into the treatment chamber. In the heat exchanger the used steam from the treatment chamber flows in the opposite direction to the water passing from the condensation chamber to the heater. The device is used in bleaching, dyeing, pressing textiles. The steam moves in a closed circuit and does not escape. Energy losses are minimised.

Title: Adjustable vehicle seat headrest - has clamping screws holding positioning legs slidable in ends of sleeve
IPC: B60N2/48
Filed: 1975-03-07
Abstract: A vehicle headrest has a mounting plate carrying a square section tube which forms a sleeve in which are fitted positioning legs. Each leg has a horizontal section sliding inside the sleeve and prevented from escaping by a stop (5) butting against a collar. This stop and collar arrangement also prevents the head rest turning about the positioning legs. After adjusting one or both legs to the width of a seat the legs are locked in position by thumb-screws.

Title: Stabilised, neutral calcium hypochlorite compsns. - prepd. by mixing dry and damp neutral hypochlorites
Inventor: HOFFER JEAN OSCAR
IPC: C01B11/06
Filed: 1975-03-21
Abstract: Prepn. of compsns. with ahigh Ca(ClO)2 (I) content stabilised against propagation of any initial decompsn., comprises mixing unstabilised, neutral dry (I) with a neutral wet (I) to give a prod. of moisture content 4-13%. Pref. dry (I) is that prepd. in the usual manner while the damp (I) is derived from the conventional prodn. of (I) before drying. Method is more economical than known methods of stabilisation since no special equipment is needed and drying costs are reduced. Typically, mixing 8.9t dry, granular (I) and 1.2t damp (I) gave, after 2 hrs., 10t of a stable compsn. with 70.7% active Cl and water content 4.3%.

Title: Pivotted tread block supports for tyre mould - held closed and heated by an annular steam chamber
IPC: B29D30/06
Filed: 1975-04-02
Abstract: In a design for the peripheral segments of a horizontal tyre mould, the tread walls are mounted on supports which can pivot on shafts at their base. The supports are enclosed by an annular chamber into which steam is admitted to provide both heat and the mould locking pressure. Appts. is esp. useful for moulding large tyres. It is simple in design with nearly all the heavy components supported by the base of the machine, and no complicated annular mechanical or hydraulic systems for applying the mould locking pressure. Differing heat treatment can opt. be applied to separate regions of the tyre carcass by independently controlling the steam pressures within the core bag behind the tread blocks and pref. also in passages alongside each sidewall.

Title: Tanker for hydrocarbons with bladder tank linings - to allow the simultaneous unloading and filling with ballast water
IPC: B63B11/04
Filed: 1975-09-25

Title: Foundation for graveyard monuments - has pointed concrete stakes hammered into ground and topped off by concrete beams providing gravestone support
IPC: E02D27/32
Filed: 1976-02-11
Abstract: The foundations for gravestones are constructed from prefabricated reinforced concrete stakes which have one pointed end and are driven into the ground by a hammering device such as a pneumatic hammer.

Title: Automatic sound level control for telephone loudspeaker - attenuates signals during pauses and adjusts amplification according to voice level
Inventor: RASMUSSEN JORN
IPC: H04M9/08
Filed: 1977-01-20
Abstract: The system provides automatic regulation of the sound level produced by the loudspeaker in a telephone system. The amplification is controlled by the voice. The microphone (M1) and receiver (HK) are conventional. There is a microphone amplifier (MF) and receiver preamplifier (FF). These are normally connected via a differential transformer (GA). In parallel with the receiver (HK) is connected a loudspeaker circuit with an attenuator (AT) and a power amplifier (KF) delivering power to a loudspeaker (HO). The attenuator is controlled by the regulator (STY). During pauses in the course of conversation the attenuator ensures maximum attenuation of the signal to prevent self oscillation of the system. When the caller speaks, a control signal is sent via the conductor (T), the regulator and via conductor (S) to establish the required level of amplification. The system avoids self oscillation, and the cutting up of the first words.
