Title: Composition of a surfacing mass
Inventor: ANDERSSON INGMAR
IPC: E01C11/24
Filed: 1981-12-08
Granted: 1985-04-18
Abstract: A surfacing mass especially for outdoor use and mainly comprising a mixture of asphalt and a stone material having a low content of fine material. The mixture comprises a little amount of fibres of a type which is not solved or softens in the asphalt, preferably mineral fibres. The fibre material has an average diameter of between 1 and 5 mu m and is added in an amount of between 0,5 and 20% by weight calculated on the amount of asphalt. The invention also relates to a method of manufacturing such surfacing mass at a mixing temperature of 140-170 DEG C or preferably 150-160 DEG C both for the asphalt and the stone mass. Preferably the fibre material is admixed in the asphalt before the mixing thereof with the stone material. The fibre material may be admixed in the asphalt at an asphalt temperature which is higher than the mixing temperature for asphalt and stone material.

Abstract: There is disclosed a line circuit for connecting a subscriber set to a switching facility to obtain an impedance match. The subscriber set is connected to first and second subscriber terminals by a two-wire line which presents a complex terminating impedance to said switching facility. A constant current source is connected between the first and second terminals for supplying the subscriber set with a constant direct current. There is a control current source coupled between the first and second terminals for supplying the subscriber set with an alternating current with the control current source having a control input. The first and second terminals are connected to respective first and second inputs of a differential amplifier whose output is coupled to a transmit line. The control input of the control current source is coupled to a receive line. In order to provide an impedance match, there is a complex impedance which is coupled between the output of the differential amplifier and the control input of the current source. The receive terminal is coupled to one input of the differential amplifier by a first resistor. The first and second inputs of the differential amplifier are coupled to the first and second subscriber terminals via separate resistors of equal value with the ratio of the first resistor to one of the first and second resistors selected to provide an impedance match for said subscriber line as connected to said switching facility.

Abstract: Circuit apparatus for supplying a loop current to a two conductor loop telephone line includes first and second differential amplifiers (11,14) each having the same gain factor. The first amplifier is coupled to one side of the line via a series resistance (12), while the second amplifier is coupled to the other side of the line via a series resistance (15) of the same magnitude. A feedback amplifier (16) has one input terminal coupled to one side of the line and another input terminal coupled to the other side of the line. The output of the feedback amplifier is coupled to the input of a variable gain amplifier (21) which has its output coupled to an input terminal of the first differential amplifier (11). The first differential amplifier receives a voltage reference source at its other input which source controls the magnitude of the current supplied to the line circuit. To accommodate different system characteristics, the gain of gain controllable amplifier (21) is varied which effectively varies the equivalent feed resistor for the subscriber line.

Abstract: @ A rotary slicer (20) for comestible products. A stationary magazine (26) supports a product upright as a rotary table (38) carries a rotary knife (40) in an orbit that passes beneath the magazine. A freely rotatable centre plate (80) of the blade facilitates movement of the blade through the product. Orbiting movement of the blade is automatically stopped with the blade remote from the magazine and electrical interlocks (109, 112) prevent operation without all protective safety covers (24,102,106) in place. A removable sharpener (172) is attachable to the top of table and operates with the blade flush with the table top. A product follower (118) within the magazine holds the product in place and urges it downward during slicing. The follower in part extends outward between the magazine (26) and magazine cover (106) to allow manual movement and release from a latched raised position, after the magazine cover is closed.
