Title: Thermochromic compsns. for thermographic recording - giving variety of colours with phenolic cpds. and chelating cpds.
IPC: B41M5/323
Filed: 1974-05-24
Abstract: Thermochromic compsns. and thermographic recording materials contg. the compsns. are claimed, the compsn. contg. at least a cpd. of formula (I) or (II): where Ri is H or electron repelling gps. in positions 5,6,7 and 8 in (I); R'i is H or electron repelling or attracting gps. in positions 4', 5', 6' and 7' and 4", 5", 6" and 7", formulae (I) and (II) and Rj is H or electron repelling gps. in positions 5,6,7,8,9 and 10 in (II). (I) and (II) (both known cpds.) produce a colour change when heated at >180 degrees C, and, when used with a reactant, give a sharper colour change at a lower temp. than when either (I) or (II) is used alone. Use of a reactant also gives colours different to that given by (I) or (II) alone. Colour obtd. varies from chestnut violet-red to pink.

Title: Passenger transport rail installation - has guard rails on doors of vehicles bridging vehicle gaps at stations
IPC: B61B1/02
Filed: 1974-05-30
Abstract: The installation has low speed vehicles (16) which move close together in stations. Each vehicle has an access door and a device sensing a vehicle ahead of it to maintain the distance between them. There is automatic opening of the door and also closing, in conjunction with the sensing device. Each vehicle has a sliding door (2b) connected to a retractable guard rail (32) comprising two cylinders (34, 34') receiving pistons (36, 36') urged outwards by springs (44, 44'). When the door opens at a station the guard rail is extended so that the end (42) of the coupled piston rods (38, 38') engages the adjacent vehicle (14) to form a barrier between the track and station platform, the springs compensating for variations in vehicle spacing.

Title: Remote sampling of cigarettes and filter tips - signal diverting items to pneumatic conveyor saves time of technicians
IPC: A24C5/32
Filed: 1974-06-20
Abstract: Samples of the products of tobacco industry machines delivering cigarettes, cigars, etc., and esp. filter tips, formed in a continuous strand and cut to length, are diverted from the conveyor moving them forward for further processing, by a signal from the laboratory up to 100 meters away. A button at the delivery point, in or near the laboratory, energises a pneumatic valve so as to eject a batch of samples from the flutes of the conveyor cylinder, into a vessel from which they are fed into a pneumatic conveyor tube. At the delivery point they are dropped one behind the other into a receptacle for quality control.
Patent FR-2275170-A1 (FR)
Title: Small double-walled lockable case - formed by blow moulding at the exit from a cylindrical extrusion die
IPC: B29C49/04
Filed: 1974-06-21

The moulded shape has projections, depressions and location points on the free edges which make possible the attachment of a handle and which are capable of pivoting with respect to the case to form a lock.
Patent FR-2281170-A1 (FR)
Title: Powder sepn into phases of different densities - in cyclone with deflecting system preventing remixing by turbulence
IPC: B04B5/10
Filed: 1974-08-06
Abstract: A cyclone for sepg. two phases of different densities which has a cylindrical body with a tangential inlet at one end and an axial outlet at the other, is fitted with a stack of deflectors, in the shape of a truncated cone, between the inlet and the outlet. These deflectors slope from the central zone to the periphery and they direct the heavy phase so that it cannot return by turbulence into the gas steam. Alternatively, the deflecting system can be continuous in the form of a helix, it may be fixed to the body of the cyclone or it may be mounted so as to rotate, and several cyclones may be mounted on a rotor with their inlets and outlets connected. The deflectors give a practically perfect sepn. because the turbulence which is engendered at the surfaces of existing types of cyclone is avoided, and none of the heavy phase re-enters the stream to be mixed with the light phase.

To avoid having to stock a variety of thicknesses, the boards are made in two parts and only the upper part (of simple rectangular section) is of variable thickness. The two parts are pref. made of the same material. The lower has the form of a lidless box, whose interior is divided by longitudinal, and possibly also transverse partitions, so that closed air cells are formed when the upper part is in place. The lower part pref. has a horizontal flange at one side; this serves to conceal the joist the plastic board is hung on.

Title: Calorimeter thermal inertia correcting system - has operational amplifiers in series, each having particular time constants
Inventor: DUBES JEAN-PAUL
IPC: G01K17/00
Filed: 1976-04-09
Abstract: The correction circuit comprises electronic operational amplifiers and is connected to a calorimeter used for microcalorimetric studies, in order to correct for thermal inertia. Thermocouples for reference and measuring chambers are mounted with their hot and cold junctions is series. The difference (5 ct) in output voltage of measuring and reference chamber thermocouples is obtained. This voltage is applied to a correction circuit (7) amplifier (8) followed by several successive stages (7a, 7b), each having particular transfer functions. Capacitors (C16, 17) in the feedback paths filter out noise and parasitic signals having rapid variations. Ganged variable resistors (R10b, 11, 13b, 14) facilitate adjustment for scaling, while avoidind stage gain modification.

Title: Cast iron mould, esp. for mfg. glass articles, e.g. bottles - has iron by non-ferrous metal, increasing heat removal from mould
IPC: C03B9/48
Filed: 1977-01-18
Abstract: Composite mould comprises a ferrous metal body (a) which defines all or part of a mould cavity; and body (a) forms another cavity filled with nonferrous metal (b) which has a higher thermal conductivity than metal (a). The result is that metal (b) removes heat from mould body (a). The composite mould is pref. made by casting one of the metals (a, b) in the other metal, so metal (b) is in intimate contact at least with that part of the body (a) which forms the mould cavity. Metal (b) pref. has heat transfer surfaces, e.g. fins, for heat removal to an ambient medium. The mould is used esp. for moulding molten glass, e.g. to mfr. glass bottles. As compared with conventional moulds, the rate of heat removal from the mould is increased, so the glass articles can be made at faster moulding speeds.
