Patent FR-2270594-A1 (FR)
Title: Portable test device for insulated poles etc. - has emitter and receiver towers supporting pole and operating indicator
IPC: G01R27/02
Filed: 1974-04-12
Abstract: A receiver and a transmitter are in the form of two towers situated apart from each other. Each has an axial electrode which just projects above the top of the tower. The two towers are fixed on a plane and hollow base which contains the direct current power supply source. The pole whose insulation is to be tested is placed so as to rest on the electrodes of the towers. If there is a fault in the insulation the receiver emits a signal. The receiver emits a low volume round signal when voltage is applied to it. Due to a fault in the bar being tested the signal then is replaced by a signal of higher volume and frequency.

Title: Hydraulic excavator with three buckets - has bucket balance beams mounted on a rotating hub
IPC: E02F3/96
Filed: 1974-04-23
Abstract: The excavator has three balance beams (12a, b, c) bearing buckets (15a, b, c) and emanating spoke-fashion from a hub (9) locating terminally on the main jib (4), rotation of this hub thus effecting a continuous excavation process. Each bucket (15) constitutes a balance beam mounted support frame (22c) which in turn bears the bin (23c), each of these components pivoting w.r.t. its support. Emptying of buckets is achieved by the pivoting inversion of bins upon encountering a machine chassis-mounted stop (26), a subsidiary bucket (18) then effecting movement of spoil to a conveyor (20). The stop (26) effects an automatic engagement with the hydraulic bucket orientation mechanism.

The flexibility (elongation is not 175%) allows appln. by extrusio(; the oxygen index is >25, and the compsn. satisfies the vertical FR-1 and the horizontal Underwriters' Laboratories tests for flame-proofing.
Patent FR-2295612-A1 (FR)
Title: Stepping motor for machine tools - has double rotor system to give ten times multiple to location speed
IPC: G05B19/40
Filed: 1974-06-18
Abstract: This stepping motor for use with machin tools is a combination of two stepping motors. The first (M2), which has a 10X stepping rate compared to the second (M1), is formed as an extension to the rotor shaft of the second motor. In this way the rotor will turn at 10x the speed of the fine adjustment motor but will give the same eventual location accuracy of the fine adjustment motor. The motors are driven by rings and collectors from two indenpendent clock generators, decade counters and comparators. The fine adjustment motor receives the unity counts whilst the other motor is driven by the 'multiples of ten' counts.
Patent FR-2278839-A1 (FR)
Title: Rough card board or fibre board includes waste fibres - recuperated from paper converting process
IPC: D21H17/01
Filed: 1974-07-18
Abstract: Rough cardboard or fibreboard includes cellulosic fibres which have been recuperated from a paper converting process. The cellulosic fibres are recovered from waste pulp or from the filtrant collected when a paper web is formed on a paper converting screen. Mineral constituents are removed from the recuperated cellulosic fibres before they are used in making the cardboard or fibreboard. The cost of processing effluent from a paper making process to confirm with legislation is reduced since the cellulosic fibres are recovered and re-used instead of being destroyed.
Patent FR-2281310-A1 (FR)
Title: Scissors-type lifting platform actuator - has cam to produce traction between fixed points inside scissors folded flat
IPC: B66F7/06
Filed: 1974-08-05
Abstract: The lifting effort is exerted by traction between two fixed points (A1, B1) in the plane of the scissors mechanism and inside it when folded flat. The points concerned are on opposite sides of the central scissors pivot pin. There can be a cam (C1) pivoting at one of the points, and acting against a cross-bar (T) to give the initial lifting effect. Stops can be provided, preventing further cam movement when the direct traction effort between the points becomes greater than the lifting effort.

Title: Vibratory screen discharge auger drive - has pendulum oscillating at screen frequency and driving shaft by one-way coupling
IPC: B07B13/16
Filed: 1974-12-23
Abstract: The drive is for an Archimedean-screw-type auger discharging the siftings from a vibratory screen, and comprises a pendulum (15) suspended from the screen casing (1, 2) near one end of the auger shaft, so as to oscillate in a vertical plane parallel to that in which the screen vibrates. This pendulum works in conjunction with an elastic component whose characteristics are such that their combined natural frequency is equal to that of the vibrations of the screen. The pendulum is coupled to the auger shaft via a one-way drive, thus indexing the shaft with each complete cycle.

Title: Pressure cooker with safety locking action - has catch member ensuring correct closure of lid and thus effectiveness of safety lock
IPC: A47J27/092
Filed: 1976-10-22
Abstract: The pressure cooker has a bayonet lock with at least one projecting lug acting as a catch mounted only on those cams of the cooker container or lid flaps which are mounted in a sector of 120 deg. Preferably only a single cam or a single flap, but at most two cams or flaps are provided with the projecting lug catch. Where the lug is mounted on the cam and if the container is not closed right up, the lug engages with the corresp. lid flap so that the container cannot be brought under pressure. Since this latter state can only be brought about when the container is correctly closed, the container can only be opened once the pressure has been released.
