Title: Converter circuit for television signals.
IPC: H04B1/26
Filed: 1980-08-20
Abstract: A converter circuit (1) for RF signals for connection to the aerial input (3) of an RF superheterodyne receiver (2). In order to avoid a separate remote control of the converter circuit (1) use is made of the local oscillator radiation which is present at the aerial input of the connected RF-superheterodyne receiver (2) as an indication of the tuning frequency selected by the user with the tuning portion of the said RF superheterodyne receiver (2). The converter circuit (1) comprises a frequency search circuit (20) in which the frequency of the oscillator radiation is detected, an RF signal selector (11) which is controlled by the frequency search circuit (20) and by means of which the desired RF signal is selected from the RF signals applied to the converter circuit (1), furthermore comprising a modulator (18) which is also controlled by the frequency search circuit (20) and in which the selected RF signal is modulated on a carrier frequency which is determined by the tuning frequency and the intermediate frequency of the RF superheterodyne receiver (2).

Title: Solid metal recessed body prodn. method - forms grooves in recess entirely by shaping blank without machining
IPC: F16D3/224
Filed: 1981-02-04
Abstract: The method produces a recessed body of solid metal, particular steel or steel alloy, the recess being undercut with grooves running in the lengthwise direction. A blank is first produced with a recess to which the grooves are connected, and then shaped into the finished article, being for use as part of a constant- velocity universal joint. The diaer. of the recess in the blank at the middle is roughly equal to the maximum diameter of this recess in the finished article. The grooves in the blank are roughly of the same depth as those in the finished article, and are produced entirely by shaping without machining. While the open end of the blank is being reduced in diameter, a radial supporting outwards pressure is exerted at intervals on the recess wall round its lengthwise axis.

Title: Repeat dialling using recall exchange equipment - holds non-obtainable number in register accessible store, with second store accessed for calling further numbers
IPC: H04M3/424
Filed: 1981-04-24
Abstract: The repeat dialling facility is for subscribers on a common control telephone exchange. The dialled number is stored e.g. on a floppy-disc and held by an abbreviated dialling code and subsequently directly accessed for re-dialling at the subscriber's request. Those subscribers with access to re-dial facilities has corresponding access to more than one store in the exchange common control register for number storage. The subscriber dials a complete number into a store and it is held there whilst the common control establishes a route through the exchange switch block to the called subscriber. If the called sub. is engaged the subscriber dials an abbreviated code to hold the complete number in that first store pending re-dial. The subscriber then clears down, lifts the receiver again and accesses a second register store for making calls. The subscriber can return to the first store to make repeated dialling attempts on his own initiation. If the first stored number becomes invalid or of no further use whilst stored the subscriber can code dial to render it invalid. If the number in the second store becomes the one he wishes to store that can be code dialled into the pending re-dial status and the first store returned to as the working store for further calls.
Patent ES-8300045-A1 (ES)
Title: Air cushion snubber apparatus and method
IPC: B21D24/08
Filed: 1981-05-11
Abstract: A floating piston 62 is mounted within the air cushion 64, 66, 68 in a press and defines a snubbing chamber 70. As the air cushion returns to its top stroke position after yieldably deforming to cushion a member within the forming press, a movable piston 56 within the air cushion contacts the floating piston 62, forcing it to move in the direction reducing the volume of the snubbing chamber. A check valve 80 is provided between a cushion chamber and the snubbing chamber which maintains the pressure in the snubbing chamber at a minimum equivalent to the pressure in the cushion chamber. As the volume of the snubbing chamber is reduced, the air trapped within is compressed to slow the motion of the air cushion. A snubber valve 78 communicates with the snubbing chamber and maintained in a closed position by the air pressure within the cushion chamber. During the snubbing action, when the air pressure within the snubbing chamber reaches a predetermined value, the snubber valve is opened permitting the air from the snubber chamber to escape through the valve to the surrounding atmosphere.

Title: Process and apparatus for reducing the environment pollution effect of exhaust and other gases.
IPC: F01N3/08
Filed: 1982-12-06
Abstract: A process and apparatus for reducing the environment-polluting effect of gases containing solid and liquid particles originating from a source, particularly the exhaust gases from an internal-combustion engine (10) involves passing the gases to be purified into a purifier (1) where an electric charging electrode (4) charges them electrically. Then the gases are caused to flow through a set of electrode plates (7) in the purifier (1). The charged solid and liquid particles contained in the gases are precipitated on the plates (7), which may be electrically charged and neutral or charged to a polarity of opposite sign to that of the charging electrode. The velocity of the gas flow in the purifier (1) may be regulated not to exceed 1 m/s. A mechanical separator may be connected in the purifier (1) downstream of the electrode plates (7). The electric charging increases the chemical activity of the oxygen as well as of the pollutants present in the gases.
