Abstract: PCT No. PCT/CH80/00014 Sec. 371 Date Oct. 5, 1980 Sec. 102(e) Date Aug. 19, 1980 PCT Filed Feb. 1, 1980 PCT Pub. No. WO80/01533 PCT Pub. Date Aug. 7, 1980.A tooth cleaning apparatus having two housing portions is disclosed. Between bot housing portions, which are connected with one another by means of a snap connection, a rubber elastic ring is fixedly clamped. This ring is inserted into a groove at a support element, to which the drive motor is attached as well as a printed circuit board. A magnetically actuable switch is mounted to this circuit board is for turning-on turning-off the motor. This switch is activated by means of a magnetic element, which is secured at an actuation element displaceably mounted at the housing outer surface. The vibration dampening ring prevents transmission of vibrations emanating from the motor to the housing and at the same time serves as sealing element.

Title: Method of varying response fineness in a control system
Inventor: NORDSTROM LENNART KNUT
IPC: G05D1/00
Filed: 1984-04-17
Granted: 1989-04-20
Abstract: In a control system with a manually manipulated unit (1) by means of which a controlled instrumentality (5) is actuated, the position of displacement ( delta ) and change in position of displacement of the manipulatable unit is determined. From this information the actuation ( theta ) is determined in dependence upon a first and a second control regime characteristic (y1, y2) for increasing and decreasing displacement positions ( delta ) respectively. When a turning point for the displacement of the manipulatable unit occurs, corresponding to a change of the displacement position from increasing to decreasing displacement positions or vice versa, actuation ( theta ) is determined in dependence upon a third characteristic that goes through the turning point and which has a smaller modulation gradient than the first and the second characteristics (y1, y2).

Abstract: Material is mfd. by folding a material, partic. polyester film (40), into a flat tubular form, pref. by folding its lateral edges towards its centre as it is advanced (60,70,72,74), heating and cooling it uniformly, pref. by passage over hot and cold rollers (90,100), while maintaining uniform tension and pressing it with rollers, applying adhesive (120) continuously along its length, and stacking it continuously on a rack (24) so that adjacent windings (48,49) become bonded together. The adhesive produces a unitary stack which is cut into straight sections to yield the honeycomb structure. Pref. the rack is rotated in a plane common to the feed direction of the strip of tubular material while maintaining uniform tension, the material being passed around a guide roller (144) mounted on a pivotal dancer arm (142) allowing the roller to move to and from the rack in controlled manner. More pref. movement of the dancer arm towards or away from the rack causes the motor feeding the tubular strip to speed up and slow down respectively. Pref. adhesive is applied to the strip in direct proportion to its feed speed. Appts. is used to fabricate expandable honeycomb insulation panels of flexible thin plastic film, partic. polyester. Appts. is designed to enable film to be permanently folded cleanly without wrinkling or warping to detract from its appearance or mode of functioning.

Abstract: The transducer which is used for detecting high local surface extensions as occur, for example, during the measurement of the deformation behaviour of tyres during travelling mode, exhibits a hose 1 which is filled with mercury 5 and connecting wires 6 which close the hose and are electrically conductively connected to the ends of the mercury column. The hose 1, for which silicone is used as material, is embedded in a loop-shape in the preextended state in a highly elastic body 2, preferably of silicone rubber, the bent sections 3 of the hose 1 and its ends 4 protruding from the body 2. Due to the preextension of the hose 1, compressions can also be detected whilst the protruding of the bent sections 3 has the effect that the measured values are uninfluenced by transverse extensions. The connecting wires 6 have a greater dimension than the inside diameter of the hose 1 and are rounded at the ends located inside the hose. This transducer represents a compact component, can be repeatedly used, supplies continuously reproducible values and can be refilled in a simple manner when mercury is lost. <IMAGE>
