Title: Telephone equipment self-energising protection device - can compensate the Larsen effect in lines with ear-piece
IPC: H04M9/08
Filed: 1974-02-14
Abstract: A telephone equipment self-energising protection device, is used with a telephone system comprising an outgoing line and a return line, two telephone receiver-transmitter units at the ends of the lines. Each telephone unit has in one of the lines a variable attenuator, an amplifier, and an earpiece. In the other line there are a mouthpiece, an amplifier and a variable attenuator. Each telephone unit also has a circuit to control the gain of the variable attenuators. A signal is taken from the line with the earpiece and at a point before the variable attenuator. The signal is passed through a detector and a filter to the first attenuator. Another signal is also taken from the line with earpiece but at a point after the attenuator to an attenuator, a detector, a comparator and then to first attenuator. The device can maintain identical and constant gain in each line.

Title: Pipeline flow counter fitting on connection - has telescopic coupling tube pairs and locking circlip on counter and connection
IPC: G01F15/18
Filed: 1974-03-08
Abstract: A connection (1) inserted into the pipeline is connected to a housing (9) which contains a counting mechanism. The housing (9) and pipeline connection (1) are interconnected by means of two pairs of coaxial tubes (4, 5, 15, 16), one pair (4, 5) on the connection and the other pair (15, 16) on the housing. These tubes define the flow path of the fluid from the pipeline through the counter. The two pairs of tubes slide over each other and are sealed to each other by means of seal rings (17, 18). A locking arrangement (21, 23, 24) ensures the locking of the housing (9) onto the connection (1) by simple sliding of the axial tubes (4, 5; 15, 16) over each other, the arrangement comprising a circlip (24) fitting in grooves (21, 23) in the tubes (4, 15).

IPC: B41F23/04
Filed: 1975-12-19
Abstract: In each throughput path of a cooling roller stand (K) there are three cooling rollers (I, II, III). In order that two webs of paper (1, 2) relating to different printing works can also be guided through each throughput path, two additional deflection rollers (U1, U2) are mounted near to the three cooling rollers in order to separate the two webs of paper from one another again. In order to be able to allow the two webs of paper (1, 2) to pass in a common throughput path through one drier (T) which is connected ahead of the cooling roller stand, an additional auxiliary roller (U) is used in order to guide one of the two webs of paper towards the other. Said auxiliary roller (U) is arranged ahead of the drier. The upper web of paper (2) is firstly guided over the first cooling roller (I) then over the second cooling roller (II) and then over the second deflection roller (U2). The lower web of paper (1) is firstly guided over the first deflection roller (U1), then over the second cooling roller (II) and then over the third cooling roller (III).

Patent FR-2309155-A1 (FR)
IPC: A23F5/16
Filed: 1976-04-29
Abstract: Green coffee beans are preferably washed with methyl ethyl ketone at a temperature near the boiling point for less than 12 minutes and after separation from the methyl ethyl ketone by filtration are treated with steam to remove further methyl ethyl ketone until the concentration is reduced to the extent that the beans, after roasting, contain an amount of methyl ethyl ketone within the normal range for freshly roasted coffee. As a result of the treatment, constituents can be removed which can be responsible in the roasted coffee for compounds which have an irritant action in the gastro-intestinal tract.
