Title: Detection and coding of states of telephone lines - enables observation of traffic and location of overloads
IPC: H04M3/36
Filed: 1973-10-24
Abstract: Observation of telephone traffic requires equipment which can detect and code the electrical states of telephone lines. The differences between received and transmitted conversation is also detected. Two telephone lines (A, B) are accompanied by a third wire (E) on which a voltage pulse appears to signify that the line has gone to a conversation state. A detector connected to these three wires comprises a circuit which detects the differences of the direct or alternating voltages that appear on the wires. This circuit has two inputs one of which is connected to either of the two telephone wires while the other input is connected to the third wire. A detector connected to this circuit determines the signalling characteristics, the conversation or ringing state.

Title: Magnetic cct generating radial magnetic field - has permanent magnetic anisotropic ferritic block associated with ferromagnetic yoke
IPC: H04R9/02
Filed: 1974-05-10
Abstract: The magnetic field is formed by a permanent magnet of anisotropic ferrite of the type used in loud speaker manufacture. A block of such material (1) has two flat faces (2, 3) each in contact with two flat plates (4, 6). The first carries a short mandrel (5) and the second a tube (7) which fits over the mandrel. The cross-sections of tube and mandrel are calculated so that they are saturated by the magnetic field induced by the main magnet and the plates. Another feature is that the volume of magnetic material used of anisotropic ferrite is almost the same as the total volume of ferromagnetic material.

Title: Screen printing press scraper holder - has tension rod counteracting bending loads caused by pressure against screen
IPC: B41F15/44
Filed: 1974-05-30
Abstract: The holder is designed to prevent bending of the scraper as force is exerted against the ends to press it against the screen. It incorporates a tension rod running parallel to the holder and pressing against the ends of it via bushes, one or both of which are adjustable to give the desired tension in the rod. The rod ends are attached to the holder ends at points on the opposite side of its centre of gravity to the scraper, so that the bar applies an unsymmetrical load to the holder in the opposite direction to the other force acting on it. The rod can be mounted inside or outside the holder. The components between rod and holder can consist of plates rigidly secured to the holder ends, with tapped holes in them accommodating the rod ends.

Title: Hole expansion for wall plug insertion - using air cooled tool with pivoted cutter
Inventor: ESCRIVA ANDRE
IPC: E21B10/32
Filed: 1974-08-12
Abstract: A hole is first predrilled to depth and the shank of the opening out tool inserted down to a stop. The shank is rotated, using a power unit, and pushed forwards in the casing. This causes a cutting blade, normally in line with the shank, to pivot outwards and form the cavity. A blower turbine is driven by the rotating shank, the air passing down an axial hole to cool the blade and exhaust the dust. This hole also contains a fixed rod used to guide the cutting tool. A collar and spring control the arc of the blade.
