Title: Machine for strapping packages in the longitudinal and transverse directions
IPC: B65B13/06
Filed: 1987-01-05
Abstract: Machine for strapping packages in the longitudinal and transverse directions, in which a plurality of individual apparatuses, as an automated unit, first of all measures the packages in all three dimensions with package longitudinal measurement, package width measurement and package height measurement. The measurement data are sent to the computer. The computer uses them to calculate, with the aid of a package-specific program, the package position manipulations for the individual apparatuses and determines the quantity required of packaging means such as squared timber and battens which are then produced by the batten production apparatus in such a manner that they are available for the respective strapping at the same time as the package is positioned at the strapping apparatus. For strappings, the packages are rotated through 90@ by the rotary conveyor and brought to the strapping machine by chain conveyor and, after completion of the strappings, are conveyed back for the following strapping in exactly this manner and together with the chain conveyor. In the strapping operations, battens or squared timbers can be laid vertically and horizontally on all longitudinal sides of the package with the aid of laying-on devices, with disc rollers of the roller track or by hand or with additional apparatuses which are not shown. The squared timbers are strapped in a flush manner at the front with the aid of retractable supporting rollers which are located on the movable supporting conveyor and horizontally support the package at its underside for the laying-on of the squared timber.

Patent DE-3716068-A1 (DE)
Title: Spade
Inventor: TATZEL FRANZ
IPC: A01B1/02
Filed: 1987-05-14
Abstract: The conventional spades for digging have only one fixed angle position for the blade. They are principally suitable for digging to turn over clods of soil. Since, frequently, digging beneath the top layer of soil is not to take place, this spade has two angle settings for the blade. By means of the conventional angle position  alpha , clods of soil are advantageously turned over. The angle position beta  serves exclusively for digging without turning over clods of soil, with the result that digging beneath the top layer of soil does not take place. Fitted on the blade 1 of the spade is an oval, funnel-shaped housing 3 which has, in the interior, a tube sleeve 4 which can pivot around the cylinder pin 7, as axis of rotation, and serves as a receiving means for the shaft 2 of the spade. The tube sleeve 4 with the spade shaft 2 is pivoted into the angle position  alpha  or  beta  of the blade, depending on the type of digging to be carried out, and is screwed to the housing 3 by in each case a screw 5 and a knurled nut 6. In order considerably to facilitate the two types of digging, a universal-joint support may be used. The length of the shaft can be varied by means of a displaceable grip sleeve. <IMAGE>

Title: Thermal steam engine with output increase/thermal steam/combustion engine
IPC: F01K3/14
Filed: 1987-05-20
Abstract: The engine operates with several steam pressure vessels, a (possibly) independent staged pressure reduction in elements similar to rotary pumps, and an increase in output by "injection" of a compressed fuel-air mixture, which largely injects itself by means of the spark ignition or auto-ignition, namely into the pressure vessel's steam space, or directly into the medium, or into the steam header. Due to cylinder (vessel) preheating by the almost completely flashed working steam, and the totality of the design features, a very high efficiency and environmentally friendly operation of the thermal steam engine are achieved. Thus it is very well suited for production of mechanical and/or electrical and/or thermal energy. Very environmentally friendly, in particular due to the secondary reduction of the pollutants such as soot components bound in water -these are isolated and reburned, or otherwise disposed of; and if hydrogen is used as fuel for the injection. <IMAGE>
Patent DE-3723660-A1 (DE)
Title: System for delaying the switching on and off of a blower motor
Inventor: GISKE DIETRICH DIPL ING
IPC: F23N5/20
Filed: 1987-07-17
Abstract: In order to achieve reliable ignition of the fuel/air mixture in the starting phase, initially only the spark plug is switched on. After it reaches its working temperature, the blower motor and the fuel pump are switched on after a delay. When the heating is switched off, initially only the supply of fuel is interrupted and the blower motor is switched off after a delay in order to permit the combustion chamber and the heat exchanger to be cooled. These switching times are to be implemented with a timer circuit and timer which operate according to the principle of capacitor charging in such a way that the times for the switch-on and switch-off delay and their ratio to one another are freely selectable. According to the invention, the switch-off delay of a timer is substantially lengthened if a resistor is connected parallel to its control voltage input after the switch-on delay time has elapsed. <IMAGE>

Title: Flexible covering for flexible adhesive tape
Inventor: GRAUMANN PAUL
IPC: C09J7/02
Filed: 1987-07-24
Abstract: In particular if it is adhesive on both sides, flexible adhesive tape has to be covered with a protective film which is known to be stiff and therefore limits the flexibility of the adhesive tape during the laying operation. According to the invention, the cover film is designed so as to be flexible by the cover tape having lateral incisions and sliding over itself or gaping apart as required at the incision points. By this means, it is possible to allow flexible adhesive tape to be laid at radii even by automatic equipment. This increases quality and saves costs.

Title: Screw (propeller) for gaseous or liquid media, especially an airscrew
Inventor: ZEIDES OTTO
IPC: B64C11/16
Filed: 1987-07-25
Abstract: A screw is proposed for gaseous or liquid media, especially an airscrew, having at least one vane, which has two individual vane blades extending at a radial distance from the centre of rotation, which vane blades form a gap between them. The first vane blade extends over approximately 30% to 70% of the vane radius. In this radial region, on the vane area which is covered by the first vane blade, the vane has an approximately corrresponding cutout. The free profile edge of the first vane blade is matched essentially without any step to the course of the profile edge of the second vane blade and the remaining part of the vane, this profile edge running such that it is curved approximately in the shape of a sabre. Two-stage acceleration with significantly higher thrust values and a higher performance coefficient is achieved, with low costs, weight and axial dimensions. The noise emission levels are considerably reduced.

Title: Pendulum suspension for mounting luminaires
Inventor: ROECK RAINER DIPL ING
IPC: F21V21/112
Filed: 1988-02-10
Abstract: Pendants, which are fastened to a ceiling, of commercially available perforated hoop iron (hoop steel, steel tape) require, during assembly, complex screw connections with spagnolets which engage in a support rail (support track) of the luminaires. A further disadvantage of known pendulum suspensions is also the subsequent height alignment, which is very difficult to achieve, of the support rails and thus of the luminaires. The novel pendulum suspension is to permit a convenient, fast and tool-less assembly between the pendant and the spagnolet, is to be adaptable in terms of height and is to ensure automatic mounting of its components to one another. This is achieved by means of a spagnolet (3) which has a spring pocket (2) for connection to a hoop iron pendant (1) which is provided with holes at regular intervals. The spring pocket (2) is formed by a rigid guide lug (21), having nose-shaped hooks (21e, 21f), and, reaching beyond the latter, by an elastically supported spring tongue (22). In the insertion slot which is located therebetween the hoop iron pendant (1) can be locked with one of its holes (1a) counter to the plug-in direction. The entire spring pocket (2) can be adjusted in terms of height relative to the spagnolet (3) by means of a screw spindle (23). The pendulum suspension is particularly suitable for mounting continuous rows of luminaires which are suspended from ceilings by means of hoop iron pendants. <IMAGE>
