Title: Method and device for securing a block of individual packages formed on a flat support, preferably a pallet
Inventor: KORTENHAUS HEINZ-GUENTER
IPC: B65B17/02
Filed: 1985-10-26
Abstract: For securing a block of layered individual packages, such as boxes or trays, formed on a flat support, points of adhesion are applied to the outside of the block, at least on the uppermost layer of individual packages, which points of adhesion extend only over the joint between adjacent individual packages and can be separated to detach the block along the overlapped joint. Such points of adhesion can be produced in a particularly simple manner by controlled spraying or droplet application of melted heat-adhesive onto the intended points of the joints. In a device for applying such points of adhesion, the block can be passed below a nozzle arrangement or a support and guide arm with spraying nozzles can be passed around the block, the nozzles being actuated to apply heat-adhesive at the desired points. For this purpose, stepwise control, control with control marks printed onto the individual packages or temporal control may be used.

Title: Process for the manufacture of porous ceramic mouldings and pressings used for this purpose
Inventor: ARTELT PETER DR ING
IPC: C04B38/06
Filed: 1985-10-31
Abstract: In a process for the manufacture of porous ceramic mouldings from plastic clays and the like, by heating a dried and preformed material up to an expansion and firing temperature of the material, pressings in the shape of rings or hollow cylinders are used. The material volume occupies 40 to 60% of the internal space of a mould before heating. The material contains up to 0.08% of finely divided carbon and 0.8 to 4% of a metal oxide, which upon heating cause the material to expand. The raw material, preshaped into rings, fills up to about 80% of a moulding box, whilst the volume of material introduced only occupies up to 55% of the moulding box capacity. This results in substantially uniform pore distribution during expansion (bloating).

Title: Filling valve for filling liquids such as beer, wine and the like
Inventor: SINDERMANN SIEGMAR
IPC: B67C3/26
Filed: 1986-03-04
Abstract: In the case of a filling valve for filling liquids such as beer, wine and the like, it is to be made possible to feed an additional gas through the return gas pipe when the gas and filling valves are closed, while retaining a valve which automatically opens under spring pressure when there is equal pressure in the bottle and the liquid vat, without the liquid valve being opened as a result and without other structural measures being necessary to hold the latter valve in a closed position. To achieve this, it is proposed that the gas pipe and/or the pipe leading on from the latter, have, beneath the valve face, two feeding pipes for preloading gas and flushing gas which can be actuated independently of one another.

Title: Sensor with electronic humidity and temperature correction
Inventor: IGELBUESCHER HEINRICH
IPC: B60H3/00
Filed: 1986-11-28
Abstract: It is known that semiconductor sensors, in particular those based on tin dioxide, are very strongly cross-sensitive to temperature and humidity variations. In some cases, the variation is so large that measurement shifts of up to 70% may occur, particularly as a result of humidity variation. The effect is of a similar magnitude in the case of temperature variations. It is known to make a temperature compensation by means of temperature sensors. The humidity can be measured technically only as relative humidity. This measurement results, however, in very different absolute humidities at different air temperatures so that the magnitude of the relative humidity cannot be used directly to correct for the humidity loss. In order to eliminate these disadvantages, it is proposed according to the invention to correct the measurement given by a semiconductor sensor using a correction factor from a microprocessor memory which is determined in accordance with the mean temperature and humidity.

Title: Sensor mechanism for the valve position in a die cavity gas removal system
Inventor: PRIEM BARRY L
IPC: B22D17/14
Filed: 1988-12-09
Abstract: A gas removal system (30) for a die cavity (14) of a die-casting or other moulding machine comprises a valve part (55), which can be moved into an open position or into a closed position to connect the die cavity to a gas release or extraction device (62). A section (58) of the valve part can be moved past a fluid-pressure inlet connection (124) in order to produce a first pressure condition, represented by a back pressure in a supply line (134), when the valve part is in one position, and a second pressure condition, represented essentially by the absence of back pressure in the supply line, when the valve part is in the other position. The presence or absence of back pressure in the supply line is detected in order to determine the position of the valve part. A control unit (150, 152) compares the valve position detected with a prescribed valve position and indicates if the valve part is in the wrong position in order to prevent melt from being forced into the die cavity. <IMAGE>
