Abstract: ABSTRACT          A movable door incorporates a proximity detection system for sensing obstructions in the path of the door.  The system comprises an array of transmitter/receiver pairs (21, 22 and 23), each pair comprising a transmitter (1) for transmitting an energy pulse, a receiver (2) located adjacent the transmitter and directed to receive any reflected transmitter pulses, and a shielding (3) for shielding the receiver (2) from receiving energy pulses directly from the transmitter (1).  At least two transmitter/receiver pairs (21, 23) are mounted on a leading edge or face of the door (12) to transmit energy pulses in a direction which is not at right angles to the leading surface or edge of the door, to monitor for obstructions in the path of the door (12).  Another two transmitter/receiver pairs (26 and 28) are mounted on the leading edge or surface of the door (12) to transmit energy pulses at right angles to the surface or edge of the door (12).  One of the latter two receiver pairs (26) has a different response to the other pair (27) so that when the door (12) approaches a stationary object the one pair (26) detects the object ahead of the other pair (27). Means are provided to respond to the output of the one pair (26) indicating the detection of an object to inhibit the output of the other pair (27).

Abstract: A method for regulating the loading of an adjustable-crown roll (10) having a stationary roll axle (11) around which a roll mantle (12) is rotatingly mounted, and by means of which roll a nip is formed with a backup roll (15). The deflection of the roll mantle (12) and/or the linear load in the nip is regulated by loading elements (13) and a backup zone supported on the roll axle (11) and acting upon the inner face of the roll mantle (12) in the direction of the nip plane (16). Upon the inner face of the roll mantle (12) of the roll (10) by means of the backup zone/zones, a sum force is produced which acts in the nip plane (16) in a direction substantially opposite to the force produced by the loading element (13), and the force effect applied by the backup zone/zones to the inner face of the roll mantle (12) is applied, examined in the direction of the circumference, to more than one point. The adjustable-crown roll (10) forms a nip with a backup roll (15) and includes a stationary roll axle (11) around which a roll mantle (12) is arranged revolving, between which roll mantle (12) and roll axle (11) loading elements (13) and backup zones are arranged to act upon the inner face of the roll mantle and are supported on the roll axle (11). The backup zones supported on the roll axle (11) are formed of at least two rows of backup-zone elements (20,21) or by a backup chamber or by at least one row of backup-zone elements and a backup chamber.

Abstract: The invention relates to a feed and to a process for its production. According to the process, a fatty substance is converted to the form of a metal salt of a fatty acid or fatty acids, and is combined with a carrier such as a con-centrated feed. In the salt form the salt is protected in such a way that it will not disturb the disintegration taking place in the rumen of a ruminant, but it is, never-theless, exploitable by the digestive system of the animal. What is essential in the invention is that the metal salt is formed into a three-dimensional matrix so that a sub-stantially liquid fat or fatty acids remain in the cavities of the matrix. In a matrix form such as this the fat is fluid, and it can be transferred and batched like a liquid. It is possible to use vegetable oils which contain unsatu-rated fats and fatty acids for the production of a feed, whereby the fats and fatty acids can be caused, by means of the protection, to pass through the digestive system of a ruminant to the milk produced.
