Title: Apparatus for analysing the traffic of public telephones and remote supervision installation for analysing the traffic of public telephones served by a plurality of telephone exchanges.
IPC: H04M3/22
Filed: 1979-03-14
Abstract: An arrangement for traffic analysing for public telephone stations which are served from a telephone exchange. The exchange transmits charging pulses to the telephone stations through telephone subscriber's lines, when calls are requested from the telephone stations. A charging pulse counter is accessed through a charging pulse detector when a call is made. The counter counts the number of detected charging pulses during an observation period allocated to the calling telephone station. An analysis initializing circuit includes time recording data delivering means for periodically reading-out the charging pulse number in the counter and for resetting the counter after the observation period. A traffic analyzing circuit is connected selectively to charging pulse counters and compares the charging pulse number of each counter to at least two predetermined charging pulse number values specific to the telephone station at the end of each observation period allocated to the telephone station. The traffic analysing circuit produces a coded signal which indicates the abnormal operation type of said telephone station when the charging pulse number is greater than one or less than the other of the predetermined charging pulse number values specific to the telephone station or when the charging pulse number is equal to zero in order to deduce whether the station is out of service.

Title: Variable capacity crossfeeding conveyer, in particular for automatic gun feed mechanisms.
IPC: F41A9/30
Filed: 1980-07-31
Abstract: A train of rotating shafts comprise an input shaft (16), an output shaft (34) and a plurality of intermediate shafts (22,28) all provided with sprockets (14,24,30) for items (52) being fed and rotating so that the items are passed from shaft to shaft. The intermediate shafts (22,28) provide a buffer facility which allows for differences between the instantaneous infeed rate and the instantaneous outfeed rate. This is achieved in that the intermediate shafts (22,28) can be swung about the input shaft (16) and outputshaft (34) respectively while maintaining a fixed spacing between the intermediate shafts (22,28). One sense of such movement reduces the outfeed rate below the infeed rate while the other sense increases the outfeed rate above the infeed rate. The apparatus may be used as a buffer between a constant feed-rate shell feed unit and a gun taking shells at a fluctuating rate.

Title: Pigment dispersions containing copolymer pigment dispersants and methods of grinding pigment dispersions.
IPC: C09K23/52
Filed: 1981-01-22
Abstract: Low-molecular weight addition copolymers of (1) (meth) acrylic acid esters of alcohols such as methanol and butanol with (2) (meth) acrylic acid esters of alcohols such as N-( beta -hydroxyethyl)oxazolidine, optionally including (3) alpha , beta -ethylenically-unsaturated monomers such as (meth)acrylic acid, (where in each instance "(meth)acrylic" means acrylic or methacrylic or both) are used as dispersants for inorganic and organic pigments and colourants which are insoluble in organic solvents, for lacquers. These pigment dispersants are compatible with practically all types of lacquer resins, such as vinyls, nitrocellulose and alkyds, and also with many other types of lacquer film-forming materials. Usually, when small amounts of unsaturated carboxylic acids, or other polar monomers and combinations thereof, are incorporated in the polymers, they become improved pigment dispersants. Such pigment dispersions, unexpectedly, can be let down with many types of synthetic resins and used by air-drying or baking the coated articles. Lacquers for metals, paints and printing inks are examples of uses for such blends.

Title: Screw press arrangement
IPC: B30B9/16
Filed: 1981-06-12
Abstract: Screw press arrangement which comprises two or more screw elements (34, 35) which are arranged side-by-side in a relatively tightly fitting press basket (30-33) having openings for drainage of fluid from the material which is fed through the press. At the feeding-in portion the core of the screw element has a relatively small diameter, while the screw threads have a large diameter and at the discharge portion the core of the screw elements has a relatively large diameter, while the screw threads have a small diameter. There are employed cylindrical press basket sections (30, 32) over the largest part of the length of the press and conically tapered press basket sections (31, 33) as a transition section (31) and as a discharge section (33) respectively. Provision is made for about 20% of the total length of the screw element at the basket section (33) of the discharge portion to have a uniformly increasing core diameter towards the discharge end and a uniformly decreasing press basket inner diameter, so that the sum of internal press basket radius and core radius in any radial plane in the discharge portion (at 33) is constant and substantially corresponds to the centre distance between the screw elements. By leaving out screw threads on the discharge portion (at 33) there is obtained an effective throttle effect in the discharge end of the press and it is preferred to let the discharge section (33) of the press basket be separately replaceable.
