Title: Step-ladder providing compact storage - has pivoting steps which are horizontal in working position but vertical when not in use
Inventor: KUEMMERLIN WALTER
IPC: E06C1/387
Filed: 1980-09-24
Abstract: A step-ladder has a pair of front legs (201) hinged to a pair of rear legs (202). The front legs consist of two main side members (203) with pivots (218) to support the steps (220). The inner ends of the steps are pivoted to a bar (211) which is also connected by a pivot (242) to the rear legs. When the legs are swung apart to their working position the bar brings all the steps to the horizontal position to provide level steps. At the same time the bar increases the rigidity of the side members. When the legs are brought together the bar swings the steps so that they are aligned with the main side members and so need less storage space.

Title: K-AMS-type filling measuring device for the brewing and beverages industry
Inventor: KLIR GEB HIRSCH
IPC: B07C5/34
Filed: 1981-02-24
Abstract: It is necessary for the filling of bottles and containers to be continuously monitored in the brewing, beverages and food industry. The following systems are predominantly employed for this purpose.   1) Optical systems which operate to determine the filled level by means of the refraction or reflection of visible light or infrared rays.   2) Systems which operate using gamma or X-rays. For various reasons, neither system provides an optimum solution, with the result that measurement of filled level is the weakest link in the filling plant. This problem has been solved according to the invention by using a microwave system in the filling measuring device. Fig. 1 shows the measuring head; the radar system consists of a transmitter (4) and a plurality of receivers (1, 2, 3). The operating principle consists in that a bottle filled with liquid causes a higher attenuation in the transmission link than does an empty bottle. By contrast with other devices for monitoring filled level, the measuring device is smaller, simpler and more reliable, and has a very low power consumption and also none of the disadvantages of the devices which operate using a hard radiation. <IMAGE>

Title: Deflection unit for a three-beam colour television tube
Inventor: SROWIG REINHARD
IPC: H01J29/76
Filed: 1981-07-03
Abstract: In the case of known colour television tubes, the two side beams (red, blue) are distorted, especially at the top and bottom of the screen, as a result of the barrel-shaped nature of the vertical deflection field of the vertical deflection coil. This distortion can be compensated for by designing the deflection field in the shape of a cushion at the level of the small winding overhang. The rotation given to an edge beam in the region of the small winding overhang of the deflection unit is then opposite to that rotation which this edge beam is given in the region of the large winding overhang of the deflection unit, so that this edge beam is no longer rotated, that is to say distorted, after passing through the complete magnetic deflection field. The cushion shape in the region of the small winding overhang is produced by suitable field formers, for example by pole elements (PS) which end in a fork shape, and vertical shunts (VS) which can be combined therewith. The invention can be used, for example, in the case of 90 DEG  colour television tubes which operate using toroidal deflection coils in the vertical deflection unit. <IMAGE>

Patent DE-3134466-A1 (DE)
Title: Follow-up control method
Inventor: KOUKAL ANTON
IPC: B23Q35/128
Filed: 1981-09-01
Abstract: A follow-up control method in machines is specified which permit machining of a workpiece along a contour which is predetermined by a drawing pattern and is traced by means of a photoelectric tracer head which is rotatably arranged about an axis, running perpendicularly to the plane of the pattern, on a coordinate carriage following the pattern contour by follow-up control in the course of the working feed and is in each case orientated in the direction of the pattern contour, the tracer head being fitted with at least two photoelectric detector elements which, as viewed in the feed direction, are arranged at a leading distance from the rotational axis symmetrically with regard to a radial plane containing the latter. If the orientation of the tracer head deviates from that of the pattern contour, an error signal is produced which re-orientates the tracer head in the direction of the pattern contour. In order to ensure that the tracer head is reliably orientated in the direction of the intended path of movement, the drawing pattern is configured in such a way that sections of the pattern contour which merge into one another or cross one another at an acute angle or at right angles and pass through one after the other in each case end at a distance from one another which is greater than the width, measured at right angles to the contour line sections, of the strips within which the projections, possible in the course of the feed movements, of the detector areas to the drawing pattern lie. Intersections are preferably additionally marked by circular points, the area of which approximately corresponds to the overall effective detector area.

Title: Sound-transmitting luminous cladding or screening of loudspeakers
IPC: F21V1/00
Filed: 1982-04-30
Abstract: The luminous loudspeaker cladding is characterised by the fact that loudspeakers (2) are surrounded by light sources (3) and a cladding (1) in such a manner that the relatively open and sound-transmitting structure of the cladding prevents the direct view of the light sources but allows a sound radiation which is direct or directed towards the listener (viewer). The cladding can be designed freely in the style of commercially available lamps. It can thus be a solid transparent decorated loudspeaker housing which accommodates the light sources in itself or it can also be a lampshade (1) which, in connection with an installation kit (4-8) encloses commercially available loudspeaker boxes (2) of certain limit dimensions and encircles them with light sources. <IMAGE>

Patent DE-3227317-A1 (DE)
Title: Valve
Inventor: LODEMANN HEINZ
IPC: F16K1/44
Filed: 1982-07-22
Abstract: The invention relates to a valve with a valve housing and with a closing part which can be actuated by means of a spindle. In installations which are, for example, operated with steam at high pressure and high temperature, it is often necessary to cool the steam in order to expand it. In many cases, cooling is achieved by adding water. To ensure uniform distribution of the added water, the steam used is introduced as spray steam simultaneously with the water into the power section situated ahead of a main valve. The valve designed in accordance with the invention is a valve inserted into the main line which simultaneously allows the removal of a quantity of spray steam when it is opened. For this purpose, the valve is designed in such a way that the closing part is provided with at least one channel, the inlet opening of which can be covered by the valve seat and, in the open position of the valve, communicates with that part of the valve chamber which is situated in front of the valve seat. The channel merges into a bore passing axially through the spindle, with the result that in the open position of the valve, part of the quantity of steam passing through the valve emerges through this channel.
