Title: Locking system for dough mixing machine head - has rotating locking disc with L=shaped slots around its perimeter used to secure U=shaped wire-loop mixing elements to mixing head
Inventor: RAEUCHLE HANS
IPC: A47J43/07
Filed: 1992-02-15
Abstract: A mixing machine agitator consists of a circular head to which a number of approximately U-shaped wire loops are attached. A safety device secures the wire loops to the head section. The safety device consists of safety disc which is coaxial with the head section and can rotate relative to it, and which has a greater dia. than the dia. of the circle on which the arms of the wire loops lie. This disc has an L-shaped securing slot corresp. to each slot in the head section in which the wire loops are located. Each L-shaped slot has a radial mounting section extending from the disc perimeter to the circle, and a circumferential locking section bounded by a locking projection. In the assembly position of the disc, the slots correspond with the slots so that the wire loops can be installed and removed. In the working position of the disc, the projections secure the wire loops in position in the slots. USE/ADVANTAGE - Used in machines for mixing dough and similar substances. The proposed device is easier to handle than the customary wire ring safety device; it does not require the use of any tools to operate, and does not have the disadvantage of the wire ring in that the wire ring can become very hot in operation and may burn the hands of those seeking to release it.

Title: Length measurement using laser diode source - contains modulation signal amplitude controller for controlling phase modulators in response to interferometer path length change
Inventor: FICHTER EDGAR DIPL ING
IPC: G01B11/02
Filed: 1992-03-21
Abstract: An optical interferometer with a measurement light path, a reference light path coupled to it and a laser diode light source is supplied by a d.c. source modulated by an a.c. signal.

The filter corner frequencies exceed the modulation signal frequency. The modulation signal amplitude is controlled to eliminate a difference between the modulator output signals. USE/ADVANTAGE - Evaluation of demodulation rotary field signal is improved and can be used with large optical path length difference changes.
