Patent CH-643784-A5 (CH)
Title: Closure device for envelopes
Inventor: FLUECKIGER DANIEL
IPC: B43M5/04
Filed: 1979-10-25
Abstract: The closure device possesses a blade-shaped guide (18), with the aid of which the passing, folded envelopes are partially opened, the envelope flap passing below the guide and the actual envelope above the guide. A moistener (22) moistens the folded-open flap and a closure device (23, 24) folds the envelope back together and exerts a contact pressure for bonding. Two light barriers (16, 21) detect the passing envelopes and the folded-away envelope flaps respectively. A gate circuit (40) emits a signal to control a distribution guide (27) whenever the detector (16) responds but the detector (21) does not. A monoflop (38) emits a delay signal by means of which the shape of the envelope flaps is taken into account in the gate circuit (40). <IMAGE>

Title: Device for measuring deformations or mechanical stresses on a material or a component
Inventor: HINTZ GERHARD
IPC: G01B5/30
Filed: 1979-11-22
Abstract: The device consists of an arc-shaped measuring element which is constructed as a spring element on which strain gauges are arranged, and of connecting elements for connecting the measuring element with the materials or components to be tested. The device exhibits a U-shaped spring element (1) with straight element sections (leg 2a, 2b, cross connection 3 between the legs) and reinforcements (4a, 4b) provided with flat surfaces between the element sections (2a, 2b, 3). On the straight element sections (for example, of the cross connection 3) of the spring element (1), strain gauges (5a, b) can be simply and reliably attached. On the reinforcements (4a, b) feed lines and protective devices can be arranged. The straight leg sections (2a, 2b) of the spring element (1) are well suited to attaching interchangeable connecting elements (I, II) such as blade and cup elements (11a, b). As a result, the device can be easily attached to the component to be tested and can be used for different applications, for example for measuring strains, deformations, crack expansions, stresses and so forth, at high frequencies and rates of shape change. <IMAGE>

Title: Device for locating failed fuel rods of a reactor fuel element
Inventor: ZINSSMEISTER ROLF C
IPC: G21C17/07
Filed: 1977-11-30
Abstract: The aim of the device specified in the main patent is to use ultrasonic heads to detect fuel rods which have failed due to the ingress of water. The present additional design is intended, in addition, further to enable mechanical deformation of the fuel rods to be detected. For this purpose, torsion springs (30) with strain gauges are provided on the free finger ends (26a) next to the ultrasonic heads (22). The fingers are inserted between the fuel rods in such a way that the strain gauges come to lie between adjacent rods. The output of the strain gauges is compared with standard values in an evaluation station, and the degree of deformation of the individual fuel rods is determined therefrom. <IMAGE>

Title: Wall clamp for venetian blind guide rails - has claws for engaging with dovetail groove ribs of the guide rails
IPC: E06B9/58
Filed: 1972-11-13
Abstract: The holding arm for the venetian blind guide rail has a telescopically extending section which can be locked at a required distance from a wall. This arrangement ensures that the guide rail can be arranged at a certain required distance from the wall and it can be moved on the supports into the correct position which facilitates fitting work. The fastening element has a housing(1) within which slides the telescopic sliding element with parallel sliding fingers(4). Each of these two fingers has at its end a cutout which engages with the dovetail shaped ribs on the guide rail(8). The fingers may be locked by a headless screw(6) which presses the clamping fingers apart so that positive contact is made between the clamping finger and the guide rail ribs.

Title: Slow speed fourdrinier paper machine
IPC: D21F1/02
Filed: 1970-07-16
Granted: 1971-05-07
Abstract: Pulp reservoir for a Fourdrinier paper making machine is designed to allow slow speed paper making. The reservoir has a closed lid so that compressed air may be used to force the pulp through onto the metal web on which the fibres are felted. The level of the pulp is adjusted so as to just cover the stirring cylinder extending across the width of the reservoir. Concentric with this rotor is a curved plate forming the corner between the bottom and front wall of the reservoir. Near the top of this plate are entrances to a bundle of tubes. The pulp is stirred by the cylinder, the design ensuring the absence of "dead spots" in the reservoir; it passes through the tubes which regulate its flow, and then passes through regulating devices onto the metal web.
