Abstract: DIFFUSION EQUIPMENT          Abstract of the Disclosure To secure accurate control over rapid diffusion such as the diffusion of zinc into gallium arsenide, the source and slices to be processed are isolated from one another during an initial warm-up period.          This is done using one vessel for the crystal slice and a second vessel for the source.  The source vessel initially blocks an opening in the slice vessel while the source and slice are brought to the desired diffusion temperature.  The source vessel is then slid through the opening to a diffusing position in which d trailing part of the source vessel again plugs the opening in the slice vessel and in which an open part of the source vessel is now in the interior of the slice vessel.  Use of this arrangement avoids the uncontrolled diffusion which occurs in current diffusion capsules during initial heating of the capsule.                - i -

Abstract: ABSTRACT     A process of producing fiberboard according to the wet method in a closed backwater system.  Chips of lignocellulose-containing material after defibration to pulp are suspended in backwater so as to obtain a pulp suspension for forming of wet sheets, which are liberated from water by compression under supply of heat, the squeezed-out water being returned to the suspension step.  The pulp obtained in the defibration is dewatered mechanically and the obtained aqueous solution of organic substance released during the de-fibration step is used for impregnation of the chips prior to the defibration, whereby said substance is bound in the pulp.

Abstract: A b s t r a c t The invention relates to a starter for an electric motor with n resistors arranged in each phase of the motor, whereby n is an integer.  By switches and a controller 2n combinations of resistors can be switched in series with the motor.  For starting the motor at most 2n combinations are sequentially switched on, arranged according to decreasing resistance value.  The on time of the combinations is preselected for attaining a pre-determined characteristic curve of current increase.  With a starter according to this invention the individual resistors can be of relatively low load capacity and therefore small and electric motors even under heavy load can be started without heavy current surges and in finely spaced steps.

Abstract: ABSTRACT     The invention relates to a method for the treatment and packaging of a food product, in particular fish, comprising a grinding or breaking down of the product so that it obtains a fluid or semi-fluid consistency. To the ground product is added a coagulating substance which consists of sodium alginate. The product is sterilized through the effect of heat, and it is then packed in sterile packages under aseptic conditions.  In these packages the product obtains solid consistency as a result of the sodium alginate reacting chemically with calcium compounds which contain strongly complex-bonded calcium ions and which are added to, or are present in, the product, to form calcium alginate.

Abstract: ABSTRACT OF THE DISCLOSURE           The present invention is directed to a method and apparatus for packing tubular bags into boxes by machinery.  The tubular bags to be packed are conveyed over various conveyor belts to a positioning belt and from the  positioning belt to a positioning table. Layers of tubular bags are then moved onto a rake-like main base that is lowered in a stepwise fashion to receive consecutive layers of tubular bags.  When the desired number of tubular bag layers is positioned on the main base, the main base is lowered to deposit the tubular bags onto an intermediate base which together with side walls makes up an intermediate container. Once the intermediate container is in a lower position, a box is pushed over the intermediate container and the intermediate container is swung through a 90° arc onto a conveyor belt.  The intermediate container is then removed from the box and by this process the tubular bags which were previously in the intermediate con-tainer are transferred into the box.  The intermediate container then swings back to its lower position.

The  clamp  base  provides  a  platform portion (3) and substantially parallel side walls (4A, 4B) extending  from  the platform  portion  to  form a  channel adapted to receive the wedge insert.  The inner surface of at  least  one  side  wall  of  the  clamp  base  provides  a channel-widening concavity (5A, 5B).  The wedge insert has a  platform  portion  (7)  and  substantially  parallel  side walls (9A, 9B) extending from the platform portion forming an  inner  channel adapted to jacket a mid-portion of the leaf spring (10).  The outer surface of at least one side wall of the wedge insert provides a convexity adapted to engage   and   substantially   fill   the   channel-widening concavity of the clamp base.  According to one embodiment, an axle clamp assembly comprises the clamp base and wedge insert and further comprises a clamp plate (12) positioned over the leaf spring opposite the clamp base and adapted to be attached thereto to hold the leaf spring securely between  them. Optionally,  a  resilient  pad  (11)  is provided mediate the leaf spring and the clamp plate.
