Title: Single stage evaporator for concentrating solns - operates with refrigerant as heating gas is suitable esp. for small units
IPC: B01D1/12
Filed: 1974-07-05
Abstract: A plant for concentrating a soln. from vapours, e.g. for crystallising out a dissolved substance from a soln., for distn., or for obtaining fresh water from salt water, comprises a forced circulation evaporator and a heat exchanger or preheater, in which the soln. receives heat from the condensn. of a gaseous heating fluid. This gaseous heating fluid is a refrigerant (e.g. NH3 or Freon (RTM)) which, after condensing in the preheater is evaporated in a first vapour-condenser, is then compressed in a compressor and recycled to the preheater. Downstream of the first vapour condenser a vacuum pump removes the inert gases. The plant is useful for small installations e.g. pharmaceutical purposes.

Abstract: The aquarium consists of a sealed tank (1) whose walls (3) are converted with a layer of waterproof cement. At a certain distance from the bottom (1a) is a perforated false bottom (4) forming a compartment (6) on supports (5). A duct (7) rises to the top of the tank from the compartment. The lower part of the duct (7a) includes a venturi (8) from which a tube (9) leads outside the tank. A bed consists of a sandwich of two coarse outer layers (10, 12) of gravel enclosing a layer of very fine gravel or sand (11) providing a suitable environment for the bacteria which are to break down faecal matter originating from the occupants of the tank, as in a septic tank. The purified water in compartment (6) is re-circulated through duct (7) by blowing air under pressure through venturi (8) from tube (9), thus forming an aspirator.

Title: Polyamide-11 coatings for aluminium battery bodies - bonded by an epoxy or phenolic resin coating
Inventor: PRINGUET MICHEL GERARD
IPC: H01G9/08
Filed: 1974-12-10
Abstract: Coatings for sealing the aluminium casings of electrolytic cells, where the outside and the inner rim of the casing is covered with a layer of epoxy resin applied as powder by electrostatic spraying to 30-50 mym thick, gelled by heating and then coated with a layer 80 mym deep of polyamide-11 prior to curing for 2-5 mins. at 180-220 degrees C. Alternatively a phenolic varnish 5 mym thick may replace the epoxy layer beneath the polyamide coating. Used for mfr. of cells required to resist continuous current discharges at voltages of 3500 V and for use over a wide range of ambient temps. e.g. to -55 degrees C. The coating is more resistant to interfacial penetration by moisture and consequent corrosion of the casing than use of heat shrunk or wrapped thermoplastic sleeving. The epoxy or phenolic coating is a compatible bonding agent for an aluminium/polyamide interface. The polyamide is sufficiently soft and flexible for satisfactory use of clamps or folded lips to retain the lid of the cell in the body mouth. Suitable for cells fitted with lids made of glass reinforced polypropylene and/or involving a seal of ethylene/propylene rubber.

Title: Wood-fired boiler - has independent secondary air shutters controlled by chains allowing min air flow
IPC: F24B9/00
Filed: 1974-11-05
Abstract: The boiler gives complete burning of the wood, there being an enclosing cone maintained at very high temperature by the combustion gases. These gases are supplied by nozzles delivering controlled secondary air, regulated by a distributor with shutters. The shutters are independent, controlled by small chains of different lengths, providing a minimum of one hot-air nozzle supplying the furnace. Closure of this prevents the boilder bursting, giving complete safety of the system. There can be a half ring halfway up the cone, enabling the combustion gas circuit to be extended and thus improve the rate of heat exchange.

Title: Punch tape control mechanism for textile machine - has sensor needles mounted to allow continuous feed of punch tape
Inventor: SAGE PAUL
IPC: D03C1/00
Filed: 1975-01-13
Abstract: A punch tape control mechanism for controlling the operation of a textile machine has pref. longitudinal control rods whose movement actually controls the operation of the textile machine and to which are connected sensor needles via e.g. a linkage. The lower ends of the sensor needles engage in punched holes of a punched tape advancing continuously across e.g. a support table so that the sensor needles are moved by the punch tape and move the control rods in accordance with the control programme defined by the punched holes in the punched tape. Control elements ensure the downward displacement of the sensor needles so that their lower ends engage in the holes of the punched tape. The punched tape is advanced continuously instead of intermittently whereby the speed of operation of the textile machine is increased.

Title: Electronic timer safety circuit - introduces delay between application of voltage and control of device to avoid transient effects during switching
Inventor: SERINDAT HENRI
IPC: H03K17/284
Filed: 1975-03-04
Abstract: The electronic timer is designed to be insented between a direct current supply source and a control element so as to effect a delay between the application of voltage and the control of the element. The timer comprises a field transistor (1) where source (2) and drain are respectively connected to one of the terminals of the supply (3) by a capacitor (4) and by a load (8). The other supply terminal (5) is connected to the source of the same transistor by a resistance (6) and to its grid by an alternating signal source (10). A circuit is provided for detecting in the load the amplified alternating signal which is used as the control signal for the control element. The safety device may be used in the field of miming for the control of switching to eliminate the effect of transient currents due to contacts bouncing.
Patent FR-2314116-A1 (FR)
Title: Braking device for objects on inclined roller conveyor - has roll rotated by object to move locking roll to wedge position
IPC: B65G13/075
Filed: 1975-06-10
Abstract: The device comprises a primary roll journalled in a housing and having a peripheral surface actuable by a moving object and a secondary roll journalled within the housing actuable by the primary roll. The secondary roll is loosely journalled in a bracket pivotally mounted on an axle coaxial with the primary roll and is biased by an adjustable pressure plate having a bevelled portion at one end to an at-rest position in proximity to the primary roll. Rotation of the primary roll under the weight of an object rotates the secondary roll by frictional interengagement against the bias of the pressure plate, whereby the secondary roll becomes wedged between the primary roll and the pressure plate bevelled portion for retarding the rotation of the primary roll.

Title: Motor or generator utilising differential magnetic field - includes windings which are non:uniformly wound over gapless cores
IPC: H02K57/00
Filed: 1975-08-01
Abstract: The electrical motor or generator works in a non-uniform or differential magnetic field. The machine has one or more windings having a rectangular cross-section. The centre of the windings houses a core carrying one or more closed loop ferro-magnetic circuits, normally ferrite or wound strip. The ferro-magnetic annuli are partly overwound by two coils whose centres are diametrically opposed. The layout of the series connected coils is such as to produce a non-uniform field to the extent that the field strengths may be in the ratio of 2:1. The annuli or toroids may be cut or uncut to allow fitting of the windings after which the air gap is re-closed.
