Title: Continuous, e.g. emulsion, polymerisation in series of loop reactors - comprises circulation without dead-space with differing controlled temp. and shear for uniform d.p. at each stage without side-reactions
Inventor: BURGERT HERWIG
IPC: B01J19/18
Filed: 1991-02-28
Abstract: Prod. is continuously circulated without dead space in a first loop with high shear and in at least one following loop with smaller shear so that a fraction of the product stream (d.p.) circulated in each loop is produced at the outlet. The arrangement consists of a connected series of 'Schlaufenreaktoren' (loop or circulating reactors, e.g. DE 3919 828) with different shearing conditions, each reactor constituting a loop. USE/ADVANTAGE - Continuous, e.g. emulsion, polymerisation of one or more monomers, e.g. SBR. The usual reaction vessel with blade stirrers gives intense turbulence and mixing only near the stirrer - even with several reactors in series, the alternate shearing and conveying gives irregular deg. of polymerisation (d.p.) and undesirable side reactions. The circulating reactor is said to avoid these by continuous conveying and uniform shearing of all the product, giving a defined and uniform d.p. at each stage.

Title: Peak value measurement, esp. of single pulses in HV measurement - using digital regulation to remove offset drift and other circuit-related error
Inventor: VETTERS GERD
IPC: G01R29/02
Filed: 1991-06-10
Abstract: A peak value measurement method involves applying a h.v. pulse to a potential divider (1) and taking a proportional output voltage from the l.v. arm (2) for electronic evaluation. Its peak value is detected (3), digitised (6) and temporarily stored in a computer (7) taking account of offset drift. After temporary storage the divider output is disconnected from the input to the electronic circuit. The supposed equipment-related error measurement part is removed form the stored value and the difference fed via a d-a converter to the input as a reference voltage instead of the output voltage. When the two values are equalised by digital regulation the digital value of the reference voltage is displayed as the error-free peak value. USE - Esp. for use with single pulses in h.v. testing.

Title: Waffle iron monitor - has pyrometers for each plate to register heat emission and determine that a baked waffle has been removed
IPC: A21B5/02
Filed: 1991-12-05
Abstract: In an industrial waffle baking appts., where the waffle irons pass through an oven, when the iron is opened and the baked waffle (4) is released, the heat emission from the upper and lower (3.1, 3.2) waffle iron plates are measured.

Filed: 1991-12-10
Abstract: An electronic control unit (13) switches a number of electrical loads (16), especially solenoid valves of a load-switching drive, as a function of the position of various information switches (19). The electronic control unit (13) has a plurality of load lines (17), which each lead to one load (19), and a central unit (15) with a plurality of electronic switches (1).

The logic status signal indicates an open load when the switch is open and a short-circuited load when the switch is closed. In the case of an open, short-circuited switch (1), the status signal suggests an open load. One information line (18) is connected like the load lines (17) via one of the electronic switches (1) to the supply voltage and leads out of the central unit (15).
