Title: Device for stacking and unstacking
Inventor: KIEDERLE RICHARD
IPC: B65G47/90
Filed: 1990-12-07
Abstract: Abstract of the Disclosure. In the context of a device for stacking and unstacking containers provided with grasping holes and more particularly for the loading and unloading of palettes with such containers, such as bottle crates and the like, comprising a gripper member having grippers adapted to be brought in and out of engagement with the said holes to pick up and deposit such container and which is mounted on a gripping carriage able to be driven on a turnover area for such crates between a pickup site and a depositing site of same, there is the improvement that the grippers for picking up and depositing the containers are arranged, and adapted to be vertically moved, to pickup and deposit the containers while simultaneously performing a pivoting motion in relation to the gripping member which is stationarily arranged in relation to the gripper carriage mounting same. This design leads to the advantage that operation on the fly of the grippers is possible and accordingly the handling rate of the entire arrangement is enhanced.

IPC: G11B27/10
Filed: 1991-06-20
Abstract: During recording the inputted data are sequentially written into a memory at one transfer rate and are read out at a second, higher transfer rate for recording on a record medium. The reading of the memory is such that data in a preset first amount are successively read from the memory to always ensure a write space in the memory which has a capacity which is higher than a predetermined second amount when the amount of the inputted data stored in the memory exceeds the first amount. During playback, the recorded data are reproduced at a second transfer rate, which is higher than a first transfer rate required for outputting the reproduced data, and are written in the memory. The thus written data are successively read out of the memory as reproduced output data at the first transfer rate.      The writing of the reproduced data to the memory is controlled so that a second amount of the reproduced data is written into the memory and an amount of reproduced data, not less than a first amount, is always stored in the memory when the amount of the reproduced data stored in the memory becomes not higher than the first given amount.

Title: Process for resistance welding and arrangement for carrying out the process
Inventor: SCHUERMANN HUBERT
IPC: B23K11/24
Filed: 1992-02-28
Abstract: ABSTRACT PROCESS FOR RESISTANCE-WELDING AND ARRANGEMENT FOR CARRYING OUT THE PROCESS A process is described for resistance-welding with a welding current which pulsates in periodic half-waves, in particular an alternating current, and which is generated from a primary alternating voltage (Up) of a welding transformer (16) and is regulated by pulse duration modulation thereof. The primary alternating voltage (Up) is chopped n times (n>1) in each half-wave during the pulse duration modulation. In each half-wave the welding current is regulated by performing n nominal-actual value comparisons of the current and by the pulse length modulation the duty ratio accordingly being influenced n times. In order to regulate the welding current, a regulator (18) is provided, having a store containing current nominal values for each chopping interval, corresponding to the welding current form, for comparing with each current actual value determined per chopping interval. In this way, not only can very short regulating times be obtained, because in each half-wave the welding current can be readjusted repeatedly, but the current form is freely selectable, because a large number of nominal values can be kept in readiness in the store for each half-wave of the current. For electric resistance-welding, in each half-wave of the welding current, a current course is selected which deviates from the sinusoidal form. AS a result, energy delivery to the material which is being welded can be accurately proportioned, which makes it possible to weld materials which have hitherto been problematical, such as very thin and or thinly tin-plated sheet metal, black plates, chromium-plated sheet metal etc, with very good welding quality and a high throughput.

It is important that the carbohydrate is a polymer when combined with the remaining components of the composition.  Polymerization of the carbohydrate prior to being combined with the other components of the composition has been found to result in an increased carbon yield upon pyrolysis of the binder.

More importantly, the binder is also free of any skin or respiratory irritants, and is in effect non-carcinogenic.
