Title: Process and device for applying a plastic cover layer onto the inner weld seam of a preserve can (tin) body
Inventor: CORDS HELMUT
IPC: B05D1/06
Filed: 1981-07-15
Granted: 1982-11-04
Abstract: The invention relates to a process for applying a cover layer of thermoplastic onto the inner weld seam of a preserve can body or the like. The plastic powder is electrostatically charged and applied as a powder trail onto the weld seam, to be covered, of the preserve can body which is connected (earthed) as a counter-electrode. The powder trail is then fused to form the cover layer. Continuous monitoring of the cover layer from the point of view of corrosion protection is necessary. For this purpose an infrared beam is directed at the powder trail by means of optical waveguides and infrared rays reflected out at the powder trail are measured. They are evaluated as a measure of the thickness of the plastic powder in the powder trail. A threshold value can be specified which ensures that the plastic cover layer fused from the powder trail satisfies all requirements from the point of view of corrosion. The invention also includes a device for carrying out the measures described, which device operates with a conventional powder application gun. An optical waveguide of an infrared radiation source with transmitter and receiver is installed in said powder application gun, the beam aperture of which is arranged downstream, in the transport direction of the can bodies, of the powder discharge slit of the powder application gun. <IMAGE>

Title: Hoop-knife splitting machine
Inventor: DORSTEWITZ RAINER DR
IPC: B26D1/46
Filed: 1983-03-31
Granted: 1984-09-20
Abstract: A hoop-knife splitting machine for splitting sheet-like material, such as skins or leather, has in the splitting region (9) one hoop-knife portion (13) and a second hoop portion (12) moved in the opposite direction. Only the hoop knife (1) has a cutting edge. In contrast, the second hoop portion (13) is formed by a centring hoop (4) not participating in the cutting function. A lateral drift of the material during the splitting operation is thereby prevented without the use of an additional wearing part.

Title: Method and device for braking a friction-welding machine
Inventor: GRUENAUER HEINRICH
IPC: B23K20/12
Filed: 1984-01-13
Granted: 1985-05-02
Abstract: In the friction-welding of parts having an exact angular position after the welding, difficulties arise when parts having cross-sections which are not rotationally symmetrical and which do not permanently overlap during rotation in the friction process are to be connected to one another. In order to achieve a perfect welded joint, the invention proposes that, during the friction process, an inert-gas atmosphere be generated in the region of the welding point of the two parts to be welded to one another. In an advantageous embodiment of the friction-welding machine according to the invention, this is achieved in that the welding point is surrounded, during the friction process, by two half-shells, between which an inert gas is introduced. <IMAGE>

Title: Device for measuring the tension of belts
Inventor: SCHULZ KLAUS
IPC: G01L5/06
Filed: 1985-02-27
Granted: 1986-09-18
Abstract: In a belt tension meter, the belt (18) is guided between two outer bearing members (10, 12), on the one hand, and an inner bearing member (16). The inner bearing member (16) is supported on a stiff measuring spring (20) constructed as a leaf spring. The deflection of the measuring spring (20) is measured by means of a dial gauge (28). In order to eliminate the influence of the belt thickness on the measurement, the clamping point (22) of the measuring spring (20) is displaced as a function of the stroke of a probe (32). An oblique bearing surface (30) for the plunger (26) of the dial gauge (28) ensures that this displacement has no effect on the stroke of the plunger (26). <IMAGE>

Title: Device for the suspended transport of loads
Inventor: THYGS ANTON
IPC: E21F13/00
Filed: 1985-03-04
Granted: 1986-06-26
Abstract: So-called lifting beams are used for the transport of loads in underground mining operations. In the case of a lifting beam with load ropes and a drive at one end of the lifting beam, the lifting beam can assume two different lengths by exchanging the centre section. The end sections of the load ropes are then changed over from the one end of the lifting beam to the other end. In this case, the use of load chains is not possible on account of a double winding drum for the load ropes. The invention now enables load chains to be used without suspension chain. The horizontal strands 31, 33 of the load chains also extend inside a box-shaped beam 5. The ends 37, 38 of the horizontal strands 31, 33 are connected via length-compensating elements 40 to the adjacent length sections 35, 34 of the adjacent load chain or the same load chain. Both load chains therefore always perform synchronised vertical movements under the effect of the pneumatic or hydraulic drive 18. <IMAGE>

Title: pH-independent moisture sensor for measuring the moisture content in bulk solids and plastic materials
Inventor: GRASER MARTIN DIPL-ING
IPC: G01N27/00
Filed: 1985-08-20
Granted: 1986-12-18
Abstract: In order to provide a cheap pH-independent moisture content, measuring of high accuracy, the damping of a plate or disk vibrating in resonant conditions is determined by measuring the amplitude. Depending on the moisture content, the vibration of the plate is impeded, the amplitude of the plate being a measure for the moisture content. To generate the vibration, magnetostrictive, piezoelectric or electrodynamic oscillators are used, the amplitude being measured by means of magnetostrictive, piezoelectric or electrodynamic transducers, strain gauges or accelerometers. The oscillator, the vibrating plate and the transducer are rigidly linked to one another and tuned for resonance (by means of an audio frequency being applied). As the vibrating plate vibrates in resonance, even small differences in damping (changes of the moisture content) produce large changes in amplitude and thus a high sensitivity of the sensor. Problems like those occurring in conductive measuring instruments and ultrasonic moisture meters as a result of shrinkage of the test material positioned in the measuring section, can be avoided with this design. As the vibration frequency used is low (from 1 to 16 kHz), it is possible to use cheap vibrator heads, amplifiers and transducers. <IMAGE>

Title: Process for producing a jacketed pipe
Inventor: HEINZ VAHLBRAUK KARL
IPC: B28B19/00
Filed: 1986-06-13
Granted: 1987-11-12
Abstract: To stiffen thin-wall steel pipes mechanically, the latter are provided with a jacketing which consists of a web (3) made of steel which is wound helically about the pipe (1) and by means of which an outer pipe (5) is held concentric to the pipe (1). The interspace (6) between the pipe (1) and the outer pipe (5) is filled with a concrete, polymer concrete or a comparable flexible, alkaline material. The filling process is expediently carried out with the pipe (1) in the vertical position, a guide function being exerted on the cementitious filling compositions flowing from top to bottom by the web (3) spot-welded to the outside of the pipe (1). By virtue of the alkaline embedding of the web (3) and the pipe (1), good corrosion protection is achieved, stiffening resulting from the composite effect of the web (3) with the aforementioned filling composition, which can be applied to a pipe in a simple manner, even on the construction site. <IMAGE>

Granted: 1988-06-23
Abstract: The two carrier bars of a head-rest for motor vehicle seats have their bottom ends inserted into a retaining sleeve anchored inside a seat back-rest. In order to retain the carrier bars at a particular height adjustment, each of these has a notched web which engages in a notch on the carrier bar side. At the same time the retaining sleeve on the top of the back-rest has a release key coupled to the movement of the notched web. The notched web is assigned to the bottom axial area of the retaining sleeve and coupled to the movement of the release key by way of a drive linkage. Since the interlocking of the notched web and carrier bar is assigned to the bottom area of the retaining sleeve, its upper area with easily accessible indirect operation of the notched web on the top of the back-rest can be used for additional functions, for example to receive a carrier bar covering free of notches. <IMAGE>

Abstract: In prior art, the movements of the cursor on a computer display device are controlled by means of a mouse, a joystick, a track ball, a digitizer or by arrow keys integrated into the keyboard. The disadvantage of these is that they require a large positioning or input surface, that the speed of movement they can achieve and their precision of input are limited, and in the fact that they are tiring for the hand. The present invention proposes a device which is easy and cheap to produce, allowing fast and accurate control of the cursor, which can be integrated into the keyboard and is not tiring for the hand. Said device for inputting XY directions, integrated into the keyboard (19), is comprised of an input device (1), a guiding device (21), four press switches (15; other three not shown), detectors (not shown), an electronic unit (not shown) and a chassis (16). The input device (1) can be moved slidingly by the user in the XY plane. The electronic unit monitors the movements of the input device by means of the sensors, determines whether the user wishes to move the cursor precisely or quickly and generates digital data which control the movements of the cursor. Said device for inputting XY directions can be used for word processing and in the field of CIM.
