Patent FR-2359383-A1 (FR)
Title: Utilisation of waste heat from steam plant - uses exhaust steam to drive vapour cycle machine delivering to condenser with heat exchanger supplying central heating system radiator
Inventor: GIRARD EDMOND
IPC: F25B30/00
Filed: 1976-07-21
Abstract: The steam power plant is provided with a condenser which is cooled by a liquid which supplies heat to a boiler through a heat exchanger. The boiler heats the vapour of a closed circuit system which drives a vapour cycle machine. The vapour is condensed in a second condenser and the liquid is pumped back to the boiler to repeat the cycle. The second condenser is cooled by a heat exchanger which supplies heat to the radiators of the central heating system of a building. The combination of a vapour cycle machine and a central heating system extracts the maximum mechanical energy and heat energy from the fuel used by the steam power plant.

Patent FR-2328785-A1 (FR)
Title: Cooling electrophoresis separation systems - using heat exchanger on the recycle after leaving electrode cell
IPC: G01N27/447
Filed: 1976-10-20
Abstract: Process for cooling electrophoresis medium involves running the sample for sepn. vertically through the sepn. column and cooling it after it has left. This cooled material is then recycled to the sepn. zone. The flow is perpendicular to the direction of sepn. It is maintained by means of a recycle pump which serves to pump it through the cooler after it has left the cell. The separator consists of a chamber contg. a series of membrane partitions mounted perpendicular to the direction of sepn. and parallel to the flow. These divide it into a number of individual cells, each with an inlet and outlet branch. The system involves the separation of charged particles by generating an electric field between two electrodes. This field can cause the creation of a pH gradient with consequent sepn. of a feed electrolyte soln. into various fractions. To obtain good sepn. it is necessary to increase the energy input but this can cause decompsn. of the sample. To avoid this cooling is used. However using coils or plates in the cells greatly increases their size. This is avoided by the recirculation system described.

Title: Metal tube hole punching machine - has rack which rotates crown wheel with cams displacing radial punches in interchangeable block
IPC: B21D28/28
Filed: 1976-10-29
Abstract: The machine for punching holes in metal tubes has interchangeable working parts enabling tubes of any dia. to be treated. The assembly has a reciprocating rack (16) which rotates a toothed and cammed crown-wheel (13). The latter is mounted coaxially about a central block (4) contg. radially displacing punches (8). The block has an axial opening (5) which receives the workpiece tube (9) on a core-anvil (10). The block has radial passages (6) which guide the punches (8), and the crown wheel includes both internal (17) and external (19) cams. The number of cams on each face corresponds to the number of punches. Movement of the rack in one sense causes the inner cams (11) to engage and advance the punch-holders.

Title: Remote control servo-mechanism - operates with counter receiving control pulses and energising electric motor driving control element
IPC: G05D1/00
Filed: 1976-12-01
Abstract: The remote-control servo-mechanism has an electric motor (1) for positioning a control element and a counter (28) receiving a variable number of control pulses, for selectively actuating the control element via the electric motor (1). The counter (28) is reset to zero in response to the first pulse of a received control pulse train and a voltage is supplied to one of several conductors (M...G) in dependence on the counter outputs. The conductors (M...G) are prevented from receiving a voltage during countering via an inhibit circuit (31) and they cooperate with the motor commutating circuit (32) such that each conductor (M...G) corresponds to a selected position of the control element.

Title: Immersion mixing head for several liquids - is solid cone section with tangential holes extending from inside to outside
IPC: B01F7/16
Filed: 1977-02-15
Abstract: Several very viscous liq. prods. may be mulled by a truncated cone section mixing head immersed in the mixt. and rotated at very high speed. The cone section has cylindrical holes bored through it from the inside. Liqs. entering the holes are violently ejected from the holes by the centrifugal forces. The ejected prods. create a continuous flow through the holes which instigates a pressure, the value of which depends on the speed of rotation. The pressure obtd. at the periphery is homogeneous. Used for mixing several liqs., even highly viscous liqs. in e.g. mulling of paints, household or industrial liqs. mulling of mud in boring installations, etc. Gives a very homogeneous product and avoids cavitation.

Title: Power plant having condenser with hot well - has side stream demineralisation system for condensate
IPC: C02F9/00
Filed: 1977-10-24
Abstract: Appts. for purificn. of condensate used in a power plant having a main condenser with a hot well as part of the steam cycle is new. The condenser is connected to receive steam from a turbine generator and the hot well to discharge to a main condensate pump. A baffle within the condenser defines upstream and downstream regions on either side with the hot well in the downstream region. Liq. flows through a passage in the baffle towards the hot well, and a weir in the upstream region holds back a pool of liq. from flowing through the passage. Liq. from the pool is pumped through a bank of condensate demineralisers spaced from the condenser and, after demineralisation, is either returned to the pool or supplied to the hot well in the downstream region. The demineralisers are located upstream of the main condensate pump so that if no demineralisation is required they may be bypassed without affecting the pump system. They can operate at low press. e.g. 50-100 psi and low temp. e.g. 134 degrees F because the liq. being treated is upstream of the hot well.
