Title: Tool fixture, in particular in mixing and beating machines
Inventor: SCHMIDT UWE
IPC: B01F7/00
Filed: 1993-05-26
Granted: 1995-01-12
Abstract: The invention relates in particular to the fixing of mixers and beaters and that of dough hooks in mixing and beating machines in which the drive shaft is designed as a hollow shaft and the locking of the tools to the hollow shaft is effected in bayonet fashion. The object of the invention is to develop a constructionally simple tool fixture, for the installation of which no additional overall length is necessary and which leads to component size reduction. According to the invention, the object is achieved in that a mechanically and/or pneumatically operating pressure element (4) is arranged within the hollow shaft (3) at the end of the tool spindle (2) and the pressure element (4) exerts on the tool spindle (2) a force component driving the tool (1) out of the hollow shaft (3).

Title: Device for the inhalation of the active substance or aroma emitted by a carrier substance
Inventor: WARETZI KLAUS
IPC: A24F42/60
Filed: 1993-11-13
Granted: 1995-03-09
Abstract: The inhalation device is intended to represent a simple, handy, versatile and reliable alternative to inhalation of aromas, flavours, scents, essential oils, drugs, alcohol, nicotine, coffee and the like. The inhalation device comprises a small tube (3) in which two inner tubes (6, 7) are installed. A stopper (8) prevents emergence of the inhalable substances. The inhalable substances (4) present in the evaporation chamber (12) are inhaled after removal of the stopper through the suction opening (1). Since the inner tubes project into the evaporation chamber and the capillary effect is also taken into account on construction, the inhalable substances are located in the space (12). This is the case even if the inhalation device is moved and tilted. Additional protection against inhalation of substances from the evaporation chamber is offered by a filter (2). The mounting (10) can be used as cigarette holder. This can facilitate giving up smoking. The inhalation device not only represents a real alternative to smoking of cigarettes, especially in rooms in which smoking is prohibited, but it is also beneficial for health. Moreover, it helps smokers to give up smoking more easily. <IMAGE>

Title: Method and device for piecing on an open-end spinning apparatus
Inventor: MESSMER SUSANNE
IPC: D01H4/50
Filed: 1994-02-12
Granted: 1995-04-27
Abstract: Before being switched on for the actual piecing operation, a fibre-feed device (110) is temporarily switched on for such a period that the fibres not required for piecing are combed out from the leading end of the sliver (2). These are prevented from being deposited on the fibre-collecting surface (136) by being discharged. The fibre-feed device (110) is subsequently switched off for such a period that the number of fibres combed out per unit time already remains essentially constant, but the fibres remaining in the leading end of the sliver are damaged only slightly by being cut off and/or intertwisted. The fibre-feed device (110) is then switched on again. Before the full intensity of the fibre flow is reached, the fibres are discharged until the possibly slightly damaged fibres have been discharged. Only then is the fibre stream, which still continues to increase, supplied to the fibre-collecting surface (136). In synchronism with this, the thread (20) is returned and, with the fibres incorporated, is drawn off again from the fibre-collecting surface (136). <IMAGE>

The brake is formed as a clamp unit (7) arranged off-centre on the bearing bolt (6) with two curve arcs extending spirally towards opposite sides from its middle point. It is tensioned in the clamp direction (y) by a spring (8).

Title: Support for soil which has been excavated e.g. during pipe laying
Inventor: GROOTEN ROBERTUS LODEWIJK CHRI
IPC: E02D17/12
Filed: 1996-02-12
Granted: 1997-08-13
Abstract: During excavation of the hole, the spoil (5) is dumped onto a support (14), which is tipped on completion of the work below ground level for back-filling. The excavation work may be for e.g. the laying of cables and piping, the hole being oblong, with excavation, laying and backfilling taking place simultaneously at different points. This can be done where space is limited, e.g. along a railway track. The support can comprise a tipping frame to which a supporting component of folding material is fixed. Tipping is by a pneumatic ram acting between this frame and a fixed one. Alternatively a sack which can be filled with gas can be used, this being so shaped that its top surface slopes on inflation.
