Title: Process and arrangement for obtaining constant product quality and safety in pasteurization plants in the event of a stoppage
Inventor: BAUDENDISTEL GERD
IPC: A23L3/02
Filed: 1991-03-15
Abstract: ABSTRACT          The description concerns a method for ensuring constant product quality and product safety when tailback conditions occur in pasteurisers and a configuration for the implementation of the method, the intention being to ensure that, in pasteurisers operated on a throughfeed principle, overpasteurisation and also underpasteurisation in the event of a tailback are reliably prevented and pasteurisation kept within very narrow tolerance limits (PE limits). For this purpose it is proposed, inter alia, that in the pasteuriser, which is operated at a constant throughfeed speed suitable to satisfy regular pasteurising requirements, a cooling process should be performed when the tailback begins, cooling over its width of action the relevant section of the pasteurising zone to a temperature which allows no increase, or a slight increase not exceeding the tolerance, in the number of pasteurisation units (PE) applied in that section to the product up to that time, the final position and time of action of the cooling process being determined by the tailback time ts. A proposed configuration for implementing the method provides for fixed spray pipes (5) or swivel-type nozzle systems (5a) for the purpose of applying cold water to be located along the zones which are capable of being switched on and off separately in such a way that, inter alia, the progression of the cooling process is performed in sections, without interruption, in progressive sequence and as determined by the step time ?t (Figure 4).

Filed: 1992-11-10
Abstract: ABSTRACT OF THE DISCLOSURE           This invention  relates  to novel  compositions  of  matter, certain derivatized fullerenes, and the  process of making them.   The derivatized fullerenes of  the present  invention contain  substituent groups in even numbers and  are produced by contacting the  fullerenes with an oxidizing  agent, such  as a strong acid  or superacid,  then adding a suitable  nucleophilic quenching  agent such  as an  alcohol, thiol or aromatic  that contains  the substituent group  to be  added. Terminal 1,y-difulleroxyalkanes  result  from trapping  with  terminal 1,y-diols where y  is the  number of carbon  atoms in  the diol.   Odd numbered derivatized  fullerenes  are  produced by  heating  the  even number derivatized fullerenes thus produced.  The compositions may  be used as crosslinking agents in polymers, core building blocks for star polymers, and stiffening agents in polymers and polymer blends.

Abstract: An optical system (10) for portable missile launcher (23) includes an objective lens (12) for receiving the entire visual and near infrared light energy emanating from a target (14) and immediate background of the target.  The light energy from the objective lens then passes through a Porro prism assembly (16) which acts to direct visual light along a first path to an eyepiece (20) and near infrared along a second path at approximately a right angle to the first path where it is received by a tracker assembly (22) and monitored.  The Porro prism (16) is constructed in accordance with this invention to include a multi-layer interference dichroic coating (18) disposed between the two prisms (34, 36) which make up the prism assembly.  This coating is of such a nature as to readily permit light energy in the visual range to pass directly through the coating, but at the same time to reflect the near infrared components along a second path bringing them to focus on the tracker assembly (22).

Abstract: Abstract Process  for drawing heated yarns,  thereby obtainable polyester fibers, and use thereof.            There is described a particularly gentle and fast process for  heating  and  drawing yarns  passing  contactlessly through a heating apparatus at high speed. The process comprises the measures of: i)   preheating a heat transfer gas to a temperature which is above the desired yarn temperature, and ii)  feeding the preheated heat transfer gas into the yarn  duct  80 that  it  impinges  essentially perpendicularly on the moving yarn along a length such that the yarn heats up to the desired elevated temperature within the heating apparatus, the length of the impingement zone being such that continuous removal of the boundary layer by the impinging heat transfer gas ensures that the yarn comes into direct contact with the heat transfer gas and thus heats up very rapidly, and iii) tensioning the yarn moving contactlessly through the heating apparatus in such z way that it undergoes drawing as it passes through said heating apparatus. The invention further relates to polyester fibers having the following properties: a tenacity index TI equal to or greater than 50 and a molecular orientation MO equal to or greater than 20 or a compliance COM equal to or less than 12 and a storage modulus index SMI equal to or greater than 100, where TI =    a1 * T - a2 * BE - a2 * S, MO =    a3 * SS - a2 * BE - a2 * S, COM =   a2 * BE + a2 * S - a4 * CAO, and SMI =  a1 T - 4 * (a2 * BE + a2 * S) + A4 * CAO +         a3 * SS - a2 * DC, in which a1 =  1 * (tex/cN), a2 = 1 * (1/%), a3 = 10 * (sec/km) and a4 = 10 * (1/%), T is the tenacity in cN/tex, BE is the breaking extension in %, S is the shrinkage in % measured at 200°C in a through-circulation oven, SS is the speed of sound in km/sec measured at 25°C, CAO is the crystallite axial  orientation in  %  expressed by the Hermann orientation function, and DC is the degree of crystallization  in  % measured by  the method of  the density gradient column.   The polyester fibers of the invention can be used  in particular  for reinforcing plastics or for producing dimensionally stable textile fabrics.
