Title: Process for the production of a milk powder
Inventor: BOHREN HANS-UELI
IPC: A23G9/52
Filed: 1986-10-29
Granted: 1991-07-09
Abstract: Abstract A Process for the production of a milk powder To produce a whole milk powder having certain character-istics of roller-dried powders, more especially a high percentage of free fats, crystallization of the lactose is promoted by seeding a skimmed milk concentrate, adding cream which has preferably been homogenized at high temperature and spraying the mixture cold under high pressure into a drying tower where it meets a stream of very hot air.     The powder obtained may be used as an ingredient in the production of sauces, desserts, ice creams and confectionery-chocolate goods.

Abstract: TITLE:  AN INVERTIBLE/REVERSIBLE TOOL FOR USE         IN A ROTARY FOOD PROCESSING APPLIANCE     INVENTOR:     James E. Williams ABSTRACT OF THE DISCLOSURE     An invertible/reversible tool for use in a rotary food processing appliance is provided for performing predetermined processing operations in a first position and other predetermin-ed operations in a second upside down position in a working bowl, which bowl contains a drive shaft for rotating the tool about a vertical axis in the bowl.  The tool has an elongated upright hub with first and second sockets positioned on opposite ends adapted to engage the drive shaft for rotating the upright hub in different directions depending on which socket is engaging the drive.  Raised ridge keyways extending vertically for at least more than half the length of the upright hub are provided to provide a positive driving relationship between the upright hub and an encircling blade hub which carries reversible blades extending outwardly relative to the axis of rotation from oppo-site sides of the blade hub.  This blade hub is slidable axially along the elongated upright hub so that the blade hub will free-ly slide down to the lower end of the upright hub when the latter hub is inverted.  The blades have first and second edges of differing characteristics which move in the same direction for performing first food processing operations and in a second direction for performing second food processing operations when the tool is turned upside down and coupled to the motor drive.

Title: Low cost transponder system
Inventor: SCHUERMANN JOSEF H
IPC: A01K11/00
Filed: 1988-07-28
Granted: 1992-02-11
Abstract: Abstract:      A transponder arrangement is described comprising an interrogation unit which sends an RF interrogation pulse to at least one responder unit.  The responder unit then transmits back data stored therein in the form of a modulated RF carrier to the interrogation unit.  In the responder unit is an energy accumulator which stores the energy contained in the RF interrogation pulse.  The responder unit further contains means which in dependence upon the termination of the reception of the RF interrogation pulse and the presence of a predetermined energy amount in the energy accumulator initiate the excitation of an RF carrier wave generator operating with the frequency contained in the RF interrogation pulse.          Further means are provided which from the output signal of the RF carrier wave generator generate a control signal which is utilized to maintain the RF carrier wave and to modulate the RF carrier to be sent back with the stored data.
