Patent DE-4105856-A1 (DE)
Title: Use of calcium sulphate with low content of water of crystallisation - as additive to fodder, binding water and improving flow
Inventor: LINDE HELLMUT DR
IPC: A23K20/24
Filed: 1991-02-25
Abstract: An inorganic flow additive for fodder comprises up to 30g of CaSo4 with less than the stoichiometric content of water of crystallisation of 12-20% and with crystal size 15-50 microns, added to 1 kg of fodder pre-mix, mineral fodder, fodder additives or mineral fodder mixts. ADVANTAGE - The additive is cheap and non-toxic, binds water (thus reducing clumping and rendering the water unavailable to microorganisms), reduces the risk of static charge, raises the amt. of Ca available to the animals, and acts as a powder coating on the components of the fodder. The risk of silicosis caused by addn. of SiO2, and of silicosis and asbestosis caused by addn. of talcum cpds. is avoided. In an example:- 500 kg of CaSO4.1/2H2O with a setting time of 8-20 mins., was added slowly, with vigorous mixing, to 10 cubic m of water at 50 deg.C. After vigorous mixing for 3-5 h, the temp. was lowered to 25-30 deg.C. The prod. was processed in a rotary vacuum filter and dried at 70-90 deg.C, giving 595 kg of CaSO4.2H2O (below the stoichiometric amt.), as crystals of size 15-40 microns and ratio of length:width of 5-10:1. This could be used to stabilise the water content and improve the flow of mineral mixts., pre-mixes, and fodder components.

Patent DE-4113428-A1 (DE)
IPC: B65D79/00
Filed: 1991-04-25
Abstract: A closure for containers has a closure top (3) which closes the mouth of the container and merges into a casing (5). The casing has a locking device, such as a screw thread, which co-operates with the outer wall of the container. The closure is characterized by a pressure-relief valve (3; 15; 5) which can be actuated by an dilatation section (15) in the casing (5) of the closure (1). Excess pressure in the container causes the dilation section to expand, whereupon the closure top (3) rises from the mouth region of the container and the excess pressure is relieved by blow-off. The excess pressure required to release the pressure-relief valve can be influenced by the shape given to the dilatation section. The dilatation section is preferably reversibly deformable, and therefore the container is tightly sealed again after the blow-off from the mouth of the container.

Patent DE-4130684-A1 (DE)
Inventor: WOLF ANDREAS DR
IPC: F01M11/04
Filed: 1991-09-14
Abstract: The invention concerns a process and device for changing the lubricating oil of, for instance, a gearbox. To ensure trouble-free operation and high availability of a gearbox, it is necessary to change the oil regularly during servicing. This is usually done manually, i.e. the oil in the gearbox (1) is removed and new oil introduced through the filler cap. This procedure is time-consuming and has high personnel requirements. Even when the maintenance ie carried out with care and attention, mistakes are likely to occur. In order to overcome these problems, the invention proposes a process and device which enables oil to be changed in a series of reproducible, recordable operations which can be carried out automatically, reliably and rapidly with low personnel requirements. To this end, the lubricating oil is removed from the gearbox (1) by a pump (12) and transferred to a storage container (6). After switching over a directional control valve (10), new oil is pumped out of a container (7) and into the gearbox (1). The process and the functioning of the device are monitored and controlled by a control unit (14).
