Patent FR-2335688-A1 (FR)
IPC: E06C1/22
Filed: 1976-12-15
Abstract: The invention relates to a multipurpose ladder which has at least three ladder parts (13, 14, 23) with rungs (18, 19, 26). Two of the ladder parts (13, 14) are essentially the same length and interconnected in an articulated manner for use as a stepladder and/or leaning ladder. The third ladder part (23) can be attached to at least one of the two other ladder parts (13, 14) for its lengthening and connected thereto. It also has an easily releasable fastening device in such a manner that a lengthening of one of the two other ladder parts (13, 14), which are interconnected in an articulated manner, is made possible both upwards and downwards in given positions relative to one another. Arranged at one end and symmetrically in relation to the longitudinal central plane of the third ladder part (23) is a fastening device (29). Fastened on each upright (24) is a shaped guide piece which surrounds the respective upright (16, 17) of one of the ladder parts (13, 14) connected in an articulated manner and which has a catch device.

Title: Electromagnetic mould for continuous or semi-continuous casting - having annular, series-connected single turn inductors and electromagnetic screens
IPC: B22D11/01
Filed: 1977-01-25
Abstract: An electromagnetic mould for continuous or semi-continuous casting of a hollow ingot comprises two annular inductors arranged coaxially within a frame. The electromagnetic field of one of the inductors shapes the external surface of the ingot and the electromagnetic field of the other inductor shapes the internal surface of the ingot. Annular electromagnetic screens are provided coaxial with the inductors. Used for casting hollow ingots and tubes of ferrous and non-ferrous metals and alloys. The inductors each have a single turn and the ratio of the height of each inductor is such that a uniform electromagnetic field intensively is provided by the series-connected inductors. Hollow ingots can be cast with the external and internal dia. in the ratio of from 1.1 to 10 using an inductor height ratio of from 1.2:1 to 3:1. The ingots have high-quality finished surfaces since current flow distortion is avoided.

Title: HF coaxial cable reflectometer tester - has tuneable oscillator in hand-held unit with standing-wave indicator with number of deflections indicating distance of fault
IPC: H04B3/46
Filed: 1977-02-25
Abstract: The coaxial cable tester is of the reflectometer type and is fully portable. The instrument is housed in a hand-held case with pistol-grip containing the batteries. A variable-frequency HF oscillator is tunable over the range 70 to 90 Mhz and is loosely coupled to the cable under test via coil and coaxial connector. The oscillator may be permeability-tuned or use varicap-diode tuning. The oscillator is tuned over its range by operating a trigger handle which also switches-on the circuit. Faults in the cable cause standing waves to be set up whose anodes can be indicated by deflections of a meter as the oscillator is swept over its range. Each deflection corresponds to a distance of approx. 5 meters between the measuring point and the fault position along the cable.

Title: Rubber seal for metal window frame - has two projecting lips one of which includes Y-shaped tip for double sealing on outer face of sash
IPC: E06B7/23
Filed: 1977-04-01
Abstract: The elastic window seal(1) is for use on metal section window frames(1), and has two projecting lips(4, 8) of which one(8) is 'Y' shaped. The body of the seal comprises a rectangular section(2) with the lips(4, 8) projecting from the top elongated face, and a longitudinal 'U' section groove(3) traversing the bottom face. The body(2), thus, forms an elastic tenon which is inserted in a frame groove whereby the lips project. The lips are of dissimilar length with the longer(8) projecting from one edge of the top face, and the shorter(4) projecting from the centre. The shorter(4) bears on the bottom face of the mobile frame, and the longer(8) bears on the outer face(5). The two lips taper towards a point, and the longer(8) terminates in a relatively small 'Y' formation (9).

Title: Electronic central heating boost circuit - has single pilot line feeding thermally coupled sensor and comparison function is performed
IPC: G05D23/32
Filed: 1977-05-12
Abstract: A boost or accelerated heating control circuit for electrically powered central heating systems, where individual heating sources have a separate thermostat. The boost supply does not require an entirely separate complex control and power supply. Boost control is achieved by the used of a single pilot line from each heated area feeding a low value resistor in series to the power supply. The resistor is thermally coupled to a heat sensor which in turn compares the resistance output with a value representing the required environmental temp. level. The thermostat system used may be either an 'all or nothing' type or proportional type.

Title: Static three=phase converter for motor - varies triggering frequency of inverter thyristors according to output voltage
Inventor: KAEUFLING FRANCOIS
IPC: H02M5/45
Filed: 1977-06-22
Abstract: The static 3-phase converter, for driving a motor, has a thyristor rectifier bridge and a thyristor static inverter. The inverter's thyristors are triggered by pulses from an oscillator. The oscillator's frequency can be varied according to the inverters output voltage -- i.e. two (or more) frequency ranges are provided for two (or more) voltage ranges. This not only enables nominal torque to be produced at high speeds (e.g. 100Hz) but at the same time relatively large torques at low speeds (e.g. 50Hz).

IPC: B41J7/56
Filed: 1977-08-17
Abstract: Typewriter has a cylindrical type carrier (13) with two annular rows of type elements (11, 12). The carrier is rotatable (10) for selection of type in any one row and is movable axially to bring the respective rows into the typing position. The axial movement is effected by a stack of piezo-electric actuators. Each actuator comrpises a pair of coaxial sheet metal discs each covered at both sides by a piezo-electric element.

Patent FR-2378374-A1 (FR)
IPC: H02B1/16
Filed: 1978-01-19
Abstract: In this device for short-circuiting two conductors of an electric installation, there is withdrawably mounted in a tube (1) made from insulating material a first terminal (5 to 8) on which there is mounted a preferably flexible connecting conductor (23) which runs in the tube. A second terminal (14 to 17) is mounted on the connecting conductors at a distance which corresponds at least to the distance of the conductors (10, 20) to be short-circuited. A short-circuiting cable (24) which is preferably guided in the lower tube end by a clamping device (25 to 27) to be operated by hand can depart from the second terminal (14 to 17). Two tubes (1), each having two terminals (5 to 8; 14 to 17) can be connected to one another via a short-circuiting cable (24) for the purpose of short-circuiting a plurality of conductors. The device is easy to manipulate and ensures perfect short-circuiting of conductors even if their distance deviates from the rated distance. The withdrawal of the first terminal (5 to 8) is performed solely by the weight of the second terminal (14 to 17), resulting in a saving of aids for this purpose and in the fact that the collapsed state of the device is adequately protected for transport.

Title: Fuel burner turbulence inducer - has turbine forming diffuser driven in opposite direction to fuel particles by part of flow from mixing chamber
IPC: B01F25/64
Filed: 1978-03-16
Abstract: The turbulence-inducing device is for a burner where liquid fuel is atomised at high pressure by a nozzle in the form of a whirlpool jet. The nozzle (11) and the combustion air (C) discharge coaxially into a blast pipe (10), in which a diffuser forms a first chamber (14) in which the fuel is atomised and partly mixed with air, and a second chamber (15) in which the mixture is burnt. The diffuser consists of a turbine (13) whose rotor is driven in the opposite direction to the particles forming the fuel jet. This is done by part of the mixture formed in the first chamber, so that the various currents passing through the turbine intermix in the combustion chamber, to form an entirely homogeneous mixture.
