Patent DE-3126260-A1 (DE)
Title: Residual pressure device on a gas cylinder valve
Inventor: GROT ILSE
IPC: F17C13/04
Filed: 1981-07-03
Abstract: The residual pressure device on a gas cylinder valve prevents soiling of the interiors of gas cylinders and of their contents, by maintaining a residual pressure during emptying to prevent emptying of the entire contents. This prevents the penetration of contaminating foreign gases from the atmosphere. It must be possible to use the residual pressure device on all gas cylinder valves, even those with very small threaded connections. It contains a spring-loaded non-return valve for removing gas in a tubular body which is screwed to the gas cylinder valve. A further non-return valve is connected in parallel to the latter valve and is connected to the same gas duct in the tubular body. The second non-return valve closes when acted upon by superatmospheric pressure from the inside and is opened by superatmospheric pressure from the outside. It takes the form of a tube valve with a valve tube above a bore which is arranged in the tubular body at right angles to the gas duct. The residual pressure device is suitable for general use with gas cylinders, especially for valuable or pure gases.

Patent DE-3137352-A1 (DE)
Title: Chair for seating in rows
Inventor: SCHNEIDER ALBERT
IPC: A47C3/04
Filed: 1981-09-19
Abstract: The invention relates to a stackable chair which is suitable for seating in rows and, accordingly, has lateral coupling elements and can be provided with an arm rest or a writing board. These chairs are distinguished by a special design of the row connecting elements (24, 25) which are arranged separately from the coupling elements (18) on the chair legs and side flanges which hold the seat part. In this case, the coupling element (18) is formed by the boundary surfaces (20, 21) of a coupling opening (19). The row connecting elements (24, 25) are thus completely independent of the coupling elements (18) and their counter-elements (42) in respect of their function, such that, by the use of chair accessories which likewise have to be fastened to the side flanges (5, 6), the function of the row connecting elements (24, 25) is not affected. <IMAGE>

Patent DE-3208102-A1 (DE)
Title: Curving conveyor belt
Inventor: TALAGA HORST
IPC: B65G17/22
Filed: 1982-03-06
Abstract: The curved path of a conveyor belt consisting of platform carriages (1, 2) arranged in a line next to one another without gaps and running on rollers (R1 to R4) is to be achieved in the curved regions irrespective of the size of the carriage and curve and the pulling chain pitch, in that in each case one (1) carriage and the carriage following next but one (1') are lowered via inclined guide planes (E1, E2) before starting the curved travel. Since the non-lowered platform carriages (2) have only three running rollers (R3, R4), those (1) resting on four rollers (R1, R2) can engage, during the curved travel, under those having the three running rollers (R3, R4), i.e. overlap the latter in an angular position. <IMAGE>

Title: Set of straightening tools
Inventor: SCHUEMER HEINRICH
IPC: B21D3/10
Filed: 1982-03-12
Abstract: Using a set of tools comprising three holders and one clamping element, posts of street lamps and road signs can be straightened in situ without the need for expensive cranes or the like. Two holders which can be clamped around the post of the street lamp are connected to one another via a flexible tension element which is resistant to clamping tension, against which the element assigned to the third holder can be displaced and supported. If this clamping element, for example a hydraulic press, which is applied exactly at the bend, is actuated, the post is pulled back into the vertical due to the points of engagement of the other two holders. This operation is assisted and the straightening of the post completed with the aid of stays which can be inserted into the post. <IMAGE>

Title: Device for examination of body parts, especially of the female breast or the testicles, using ultrasound
Inventor: PIRSCHEL JOERG DR MED
IPC: G10K11/35
Filed: 1982-03-23
Abstract: The invention relates to a device in which the body part (4) to be examined projects over an opening (3) in a liquid vessel (6) containing a liquid which is highly conductive of ultrasonic waves and via which the body part can be coupled to a rotatable ultrasonic scanning system (12), and in which the liquid vessel is located in a second vessel. It is the object of the invention to provide a device which does not give rise to any problems with regard to sealing and electrical insulation of the ultrasonic scanning system. It should preferably be possible to employ a commercially available ultrasonic scanning system which can be removed again if desired and be used at another site. This object is achieved, according to the invention, in that the second vessel (9) is free from liquid and that at least this vessel is rotatable about an axis of rotation (38) pointing in the direction of the opening (10) in the liquid vessel (6) and that the ultrasonic scanning system (12) is located in the second vessel, such that it is coupled to the liquid vessel (6) and is rotatable together with the second container at the coupling site. <IMAGE>

Title: Packaging container, especially of cardboard
Inventor: SCHWARZ GUENTER
IPC: B65D43/10
Filed: 1982-05-05
Abstract: The container body (2) has U-shaped incisions (10) forming tongues (14) along the edge (8) of its opening (6). The tongues can be pushed onto correspondingly dimensioned recesses (13) on the flange part (12) of the container lid (7). The upper wall part (18) of the recesses (13) engages in the transverse part (20) of the incisions. The lid (7) is thus retained on the container counter to inwardly and outwardly directed forces. Additionally, the container side walls (4) are reinforced by this connection between the lid and the container body against bending out. The lid (7) can easily be produced by vacuum forming. The container body (2) can likewise be produced easily by four folds of a rectangular cardboard sheet. The lid can be removed non-destructively. <IMAGE>
