Filed: 1983-12-09
Abstract: A flocculating agent for use in water purification technology and papermaking technology is described, as well as a process of producing the flocculating agent which is the reaction product of sulphate ion-containing polymeric aluminium hydroxy chloride and one or more cationic polymers preferably selected among polyacrylic amide, polyamide amine and polyethylene imine. The most preferred cationic polymer is polyacrylic amide. The flocculating agent is produced by mixing an aqueous suspension of sulphate ion-containing aluminium polyhydroxy chloride having a solids content of 20-30 parts by weight with 0.3-60 parts by weight of cationic polymer, based upon 100 parts by weight of sulphate ion-containing aluminium polyhydroxy chloride, and by heating the mixture for 2-4 h at a temperature varying from about 80° C to the boiling of the mixture.

Abstract: A protective device for a station wagon type vehicle comprises a grating, which can be mounted in the tailgate (1) opening (2) so it is sealed. In this invention, the top edge (9) of the grating is fastened on the inside of the tailgate top (4) by means of swing mounts (11, 13) and telescopic devices (10, 12) so that it can be swung. The lower edge (6) of the grating is fixed in the vehicle floor just within the position the inside of the tailgate assumes when it is closed by means of locking devices (14, 15). The shape of the grating mirrors that of the tailgate (1) inside. The swing mounts (11, 13) can be used to swing the grating to a position next to the inside of the tailgate and a spring clamp (17) can engage in the tailgate to lock it in this position. The telescopic devices (10, 12) comprise rods (12) that slide into and out of a tube (8) and can swing in the mountings due to their bent sections (13).<IMAGE>

Abstract: The present invention relates to a hollowing machine for vegetables and fruits comprising a frame (1) with a lower table (2), a central table (3), an upper table (4) and outermost a step-by-step pivoting table (7), placed above the upper table. The pivoting table is provided with recesses or pockets for keeping a vegetable or fruit, e.g. a head of cauliflower. The machine comprises a supporting device (103) and a holding device (104) for centering and holding the head of cauliflower in the correct position. Below the outer pivoting table (7) and the upper table (4), centered under one of the recesses, a device of the iris diaphragm (83) type is arranged and straight under this diaphragm a knife head (46) and control devices (107, 36) for controlling the up- and downward movements of the knife head are arranged. The knife head comprises i.a. a cutting knife (50), which when the iris diaphragm opens is brought up through the opening of the iris diaphragm and cuts out a part of the vegetable or fruit which rests on the iris diaphragm. The knife head, the knife and the iris diaphragm are synchronized with the step-by-step pivoting table and depends on and is controlled by the diameter of the head of cauliflower. When the knife has cut out the part in question of the vegetable or fruit the knife is immediately withdrawn at the same time as the cut out part falls down through the opening of the iris diaphragm and out to a collecting unit. The remaining part of the vegetable or fruit may thereafter be transported to a separate collecting unit.

Abstract: A method for producing silicon substrates includes growing the silicon crystal body at a relatively high rate of growth. It has been found that the growth rate of the silicon crystal body exerts substantial influence upon generation of crystal defects in the silicon crystal body or silicon substrate. Furthermore, the oxygen concentration in the silicon crystal body or the silicon substrate is significantly higher than in conventional silicon crystals or substrates. The high growth rate of the silicon crystal body suppresses separation of the oxygen from the crystal body. This reduces the number of defects or faults formed in the crystal body during heat treatment during production of the semiconductor devices. In the preferred process, according to the present invention, the growth rate of the silicon crystal body is greater than or equal to 1.2 mm/min. Furthermore, the preferred oxygen concentration in the grown silicon crystal body is selected to be greater than or equal to 1.8 x 10<18> cm<-3>. <IMAGE>

Abstract: In operating an excavator it is useful to be able to change the direction of the accessory, such as the dipper ladle, by turning the accessory in the horizontal plane relative to the dipper arm. By providing an adjustable swivelling joint (4, 6) between dipper arm and accessory turning may be achieved without using any drive for the actual turning. The adjustable swivelling joint substantially comprises an inner ring (4) with transverse grooves (9) and an outer ring (5) arranged to match the inner ring (4), the outer ring being connected with a base plate (6) supporting a coupling device (10-14). On turning, the coupling device will release the inner ring so that it may be turned relative to the outer ring. The force required for the turning is provided by the excavator, which through its movement and with the ladle resting on a firm underlayer forces the ladle (13) with the ladle support (16) to be turned relative to the dipper arm (1). On setting a new position, said position is fixed when the power supply is interrupted, and a spring (12) will return the cone-shaped wedge (10) of the coupling device to the groove or the recess (9).
