Abstract: The present invention relates to mixed crystals comprising a) leavening agent and b) 0.1 to 5000 ppm by weight of crystallization aid, based on the total amount of the leavening agent, in the form of at least polymer, wherein when hydrophilic cellulose derivatives are used as crystallization aid, the amount thereof is reduced to less than 100 ppm by weight, based on the total amount of the leavening agent. The present invention further relates to the production of the mixed crystals and to the use thereof in the production of bakery products, as acid regulator in foods, in the production of cosmetics products, in the synthesis and formulation of pharmaceutical products, and also as blowing agent in industrial processes such as, for example, the production of foam rubber, or for fire-extinguishing formulations. The present invention relates, furthermore, to the production of bakery products.

Abstract: A facility is described for the automatic recognition and differentiation of single-channel or dual-channel electronic sensors, which are connected to a dual-channel safety combination with two connecting line pairs for emergency stop facilities in the form of electronic sensors or emergency stop buttons, with a first connecting conductor pair being provided for single-channel operation and the first and a second connecting line pair being provided for dual-channel operation of the safety combination, said facility comprising an ohmic resistance arranged in at least a first connecting line of the second connecting line pair and a transistor connected by its emitter or collector to a first side of the ohmic resistance and by its base to a second side of the ohmic resistance in such a manner that during a current flow through a dual-channel electronic sensor connected to both connecting conductor pairs a voltage drop at the ohmic resistance switches the transistor, so that an output signal is generated at the c

Abstract: The present invention relates to metallated or unmetallated porphyrin derivatives which have varying amphiphilic properties and which may be bonded to polymers, and to processes of their preparation. The present invention further relates to photosensitizers comprising said porphyrin derivatives, and to the use of said photosensitizers for the catalytic formation of singlet oxygen.

Abstract: An assembly for applying a torque from an output shaft to an input shaft of an apparatus, such as a multishaft extruder, and for measuring the applied torque. The assembly includes a connecting sleeve for torque-transmittingly coupling the output shaft with the input shaft; and a torque measuring device having expansion measuring strips, a signal amplifier, a transmitting ring antenna and a receiving antenna. The connecting sleeve has a first length portion carrying the expansion measuring strips and a second length portion carrying the signal amplifier and the transmitting ring antenna. A torque-transmitting arrangement torque-transmittingly couples solely the first length portion of the connecting sleeve with the output shaft and the input shaft, so that the second length portion of the connecting sleeve is free from a torque-transmitting connection with the input shaft.

Abstract: A nail driving tool is disclosed as including a magazine (9) which, in turn, includes a guide path (7) for guiding a plurality of nails (10.sub.1, 10.sub.2, 10.sub.3. . . ) which are preferably disposed in the form of a nail strip. The guide path (7) is open at an outlet opening (2) from or through which a first or leading nail (10.sub.1) is conveyed into a discharge channel (3). A driving mechanism, such as, for example, a pneumatic driver (11) is disposed within the discharge channel (3) for driving or discharging the leading nail (10.sub.1) from or through the discharge channel (3). A cantilevered leaf spring (8) has one end thereof fixedly mounted upon the magazine (9) while the opposite free end thereof engages the second nail (10.sub.2) disposed immediately upstream of the leading nail (10.sub.1) so as to retain all of the nails disposed upstream of the leading nail (10.sub.1) while the leading nail (10.sub.

Abstract: A temperature sensor for mixing and kneading vessels, particularly for rubber kneaders, which is sealingly mounted in an opening in a housing wall of the vessel to project into the material to be mixed and/or kneaded. A thermocouple is mounted in the measurement tip for transducing measured temperature into signals transferred to a measurement device. The measurement tip comprises a thin-walled tube of relatively large diameter made of high-strength low heat-conductivity material. The tube has a conical portion at the tip end of which is mounted a high heat-conductivity material connected to the thermocouple. The outer surface of tube is coated with an insulation layer of ceramic at least in the region in which the tube is engaged in the housing wall.

Abstract: The present invention comprises a nail driving device with a magazine for nails held together in nail strips, with a nail transport device, wherein the nail strips are pressed in the direction of a fixed stop surface by means of a spring element, and moved in the direction of the exit channel of the device mouthpiece.

Abstract: An annular cushioning buffer (1) is fabricated from an elastic material, such as, for example, polyurethane, for use in connection with fastener-driving tools for impact load distribution and energy absorption purposes. The buffer (1) includes an axially central passage (2) having an axis (M), as well as a plurality of axially extending holes (3) equiangularly spaced about the annular buffer (1) along a circular locus thereof. Radially extending slots (6) extend toward and open onto or pierce inner and outer peripheral or circumferential surfaces (4,5) of the buffer (1) in an alternative fashion so as to uniformly distribute the load impressed upon the buffer (1) by means of the striking piston of the fastener-driving tool.

Abstract: A nuclear energy installation having at least one gas collecting chamber so divided through the intermediary of separator walls that the gas conduits and/or gas distributors of each cooling gas circuit discharge into an isolated or separate gas chamber which, through one or more pressure-compensating apertures with a collective high flow resistance in comparison with the flow resistance of the remaining gas conduits and gas distributors, is connected with at least one further gas chamber of the same gas collecting chamber whereby the separator walls evidence a stiffness or rigidity enabling them to withstand the pressure differentials which are produced between the gas chambers upon the rupture of a pressure-supporting wall structure or gas conduits.

Abstract: A sinter crushing machine having a crushing screen and a crushing roll, the screen having hollow teeth with nozzle means for directing a spray of coolant over the working surfaces thereof and the roll having hollow spikes with nozzle means for directing a spray of coolant, such that the working surfaces of the screen and roll are respectively cooled by a substantially uniform amount of coolant at substantially uniform temperatures.

Abstract: A heater plate for plunger-type molding presses comprises a plurality of electrically heated heating elements which are inserted into holes through the plate. These holes are disposed in rows parallel to the peripheral outline of the plate so that the density of the heating elements decreases toward the center of the plate. The heating elements are interconnected and also connected to a temperature control device so that the heating elements can be selectively heated whereby the plate can be uniformly heated in spite of higher heat loss at marginal portions of the plate.
