Abstract: A transporting device with a transporting ball (21) which is mounted in a bearing sleeve (23) using bearing balls (22) is known. Spring devices (26) are provided for holding the bearing sleeve (23) in a casing (20) in a resilient manner. The transporting ball (21) is held on the bearing balls (22) by means of a holding ring (29). First holding devices (28) are provided in order to hold the casing (20) essentially perpendicular to the top of a holding surface (10) in opposition to a force acting on the transporting ball (21). The casing (20) is held in the recess of the holding surface (10) by means of a second locking device (34). The latter are seated on the upper end of the casing (20). To simplify assembly and disassembly, it is proposed to make the external outline of the second holding device (34) larger than that of the casing (20) and to provide locking devices (35, 36) for locking in the holding surface (10), designing the second holding device (34) in such a way that it can be removed as a discrete part when the locking devices (35, 36) have been released so that the casing, with the parts which it contains, can be removed from the recess (13, 14) in the holding surface (10).

Inventor: MESSERLI RUDOLF
IPC: A01M21/04
Filed: 1992-04-25
Abstract: Arranged in the housing (1) are a gas/air mixing chamber (2) and a porous ceramic plate (4). Gas is introduced through a gas supply tube (6) in a gas- and air-inlet element (3) via a pipe connector (5) and a nozzle (17). At least one air-inlet opening (7) is formed in the side wall of the gas- and air-inlet element (3). The gas- and air-inlet element (3) is surrounded by a wind screening sleeve (8). This produces an air inflow space (9), so that disturbances caused by side wind subside at the latest by the air-inlet opening (7) and a constant gas/air mixture prevails in the gas/air mixing chamber (2) and consequently uniform combustion is ensured in the ceramic plate (4). The ceramic plate (4) and the protective net (10) laid underneath are surrounded by an enclosing extension of the side walls (11), so that a protective frame is formed. Between the lower edges (12) and the ground to be worked in each case there is formed by the punctiform bearing of the edges (12) an enclosing slit arrangement for the outlet of the exhaust gas, so that there is the greatest possible distance between the exhaust-gas outlet point and the ceramic plate (4), so that wind likewise has the smallest possible influence on the combustion in the pores. <IMAGE>

Abstract: According to the invention, it is specified that the concave dust protection (23) of a cone-like loudspeaker (10) is to be formed from hot press-moulded foam. This has the advantage that concave dust protections (23) formed from this material are to a great extent immune to the effects of fingerprints and simple adhesives can be used to connect them to the diaphragm. If the bead (14) and the concave dust protection (23) are formed from the same foam, this has the advantage that, with a suitable press mould design, the concave dust protection (23) can be formed from the part of the foam mat which would otherwise be left over in the centre of the foam mat if just forming a bead (14). <IMAGE>

Abstract: A ferroelectric liquid crystal device showing improved uniform alignment characteristic and switching characteristic is constituted by a pair of an upper substrate and a lower substrate, and a chiral smectic liquid crystal disposed between the upper and lower substrates. Each of the upper and lower substrates has thereon an electrode for applying a voltage to the liquid crystal and a uniaxial alignment film. The alignment films on the upper and lower substrates are provided with uniaxial alignment axes which cross each other so that the direction of crossing of the uniaxial alignment axes from the lower substrate to the upper substrate is identical to the direction of helical twist in cholesteric phase of the chiral smectic liquid crystal, and the chiral smectic liquid crystal is disposed in such an alignment state that the liquid crystal shows a pretilt angle α, a cone angle Ⓗ , an inclination angle δ of SmC* layer, and an apparent tilt angle ϑa satisfying relationships of;        H⃝ < α + δ           and Ⓗ > ϑa > Ⓗ/2. The crossing direction may preferably have a polarity (taken as "positive" in clockwise direction and "negative" in anticlockwise direction) which is the same as the polarity of the spontaneous polarization of the liquid crystal.

Abstract: This invention relates to a hardening material for medical and dental use, in which at least either one of α-tricalcium phosphate and/or tetracalcium phosphate is an essential component. 
     Since the hitherto-known hardening material for medical and dental use, in which α-tricalcium phosphate and/or tetracalcium phosphate are essential components, have used an aqueous solution of one kind of organic acid as a setting solution, it was difficult to safisfy working efficiency for kneading as well as time necessary for hardening. Thus, the subject of this invention is to provide a hardening material for medical and dental use by which the working efficiency for kneading and the time necessary for hardening are satisfied. 
     To solve said subject, the hardening material for medical and dental use relating to this invention involves, as a hardening adjuster, use of the following: (a) tannin and an organic acid, or (b) at least two kinds of organic acids.

Abstract: An arrangement for radially expanding a tubular gasket (16) includes a sliding sleeve (24) and a compression sleeve (20). The sliding sleeve is formed of a thin membrane of relatively rigid material, such as nylon, hypalon or polyester. The sliding sleeve (24) is positioned adjacent an inner surface of that portion of the tubular gasket to be expanded. The compression sleeve is disposed immediately adjacent the sliding sleeve such that the sliding sleeve serves as a slip plate for the compression sleeve when the sleeves are expanded against the inner surface of the tubular gasket. The sliding sleeve may be attached to or integrally molded into the inner surface of the tubular gasket (16). Another aspect of the invention involves forming the compression sleeve so as to allow it to be locked in any one of a plurality of expanded positions. The locking mechanism may be integrally formed with the compression sleeve, or may be formed as a separate element which may be molded into, or otherwise pre-attached to, the inner surface of the tubular gasket.

Abstract: An energy-absorbing crash barrier (10) is provided with multiple energy-absorbing elements (12,14,16). Each element includes an expanded metal sheet (30) formed as a tubular column (18) which is internally braced with foam. In some of the sections multiple metal columns (60,62,72,74,76) are provided, one eccentrically positioned within the other. The expanded metal columns provide the major energy-absorbing elements of the barrier, and the eccentrically positioned columns define a preferred bending direction which tends to redirect an axially impacting vehicle away from a hardpoint. The columns in the individual elements are graduated in axial stiffness such that a forward section tends to collapse before the rearward sections, thereby providing staged collapse.

When the handles are kept apart from one another, a collapsible tube (16) can be inserted into the slot formed between the engaging plates (32,140) of the dispenser. When the handles are squeezed together, the engaging plates apply force to the sides of the tubes, thus squeezing out a very controlled amount of highly viscous material. The dispenser is very easy to use, in that it can produce a bead of highly viscous material upon a target having a very narrow line width, and having great positional accuracy.
