Title: Hand blown glass bell - is formed by two bulged expansions in tube blank between open and closed spike to be pressed together for the bell shape
Inventor: GLASHUEPFER INH HEINZ ROESSNER
IPC: C03B23/07
Filed: 1990-08-28
Abstract: To produce a hand-blown glass bell, such as a decorative Christmas bell, a blank is drawn from a glass tube so that the cylindrical blank ends in a closed spike at the drawn end, and the other end of the blank is formed into an open spike for the hanging eyelet. The blank is blown to give two spherical expansion zones, of different dias., where the smaller bulge at the open spike side and the larger section at the closed spike. A projecting ring rib is formed on the outer surface of the larger bulge, by a light compression along the axis of the blank, to position it between the centre of the spherical bulge and the closed end. Both the spherical bulges are pressed together to form a bell shape without a break in the profile line. The closed spike is separated from the section projecting beyond the ring rib, and an eyelet to hang the clapper is fused into place at the cutting point. The closed section is then pressed into the interior of the glass body, to place the clapper eyelet within it. The open spike is detached. ADVANTAGE - The method allows hand-blown bells to be produced with a greater height than 12 cm

Abstract: The invention relates to a floor element for use in shower baths and other shower areas. According to the invention, the floor element is a moulding with a square, circular or other base, in which the standing area (1) for the user is surrounded and bounded by the drainage channel (2) for the waste water and the water outlet (4) is integrated in the drainage channel (2). Adjoining the drainage channel (2) on all sides is a drainage area (3). The latter and the standing area (1) for the user are sloped towards the drainage channel (2). In a further development of the invention, a standing/sitting device (6') is provided, which is connected either to the water outlet/siphon trap (4) or is inserted in the drainage channel (2) and which has a leaning/sitting bar (11') at the upper end or is designed as a solid support. Consequently, the object is achieved of providing, for easier use, a shower which has no outer walls like conventional shower baths and of obtaining more reliable collection of the shower water and more cost-effective production than in the case of shower planes produced manually with tiles and integrated into the floor. <IMAGE>

Patent DE-4113052-A1 (DE)
Inventor: BECKER KLAUS
IPC: A01F29/12
Filed: 1991-04-22
Abstract: 2.1. In conventional conveying devices (24) for choppers, which followed a chopping drum and preceded a discharge shaft (26), problems could arise in the delivery of material when only a little material had to be conveyed and acceleration which could be imparted to this was too low. 2.2. The improved conveying device (24) contains a rotor (32) rotating between side walls (34) and having disc-like supporting elements (96) for receiving the paddles (98). Both in the side walls (34) and in the radially extending supporting elements (96) are provided orifices (120) or perforations (102) which can be brought into alignment with one another. In this way, the flow per unit volume can be supplemented by sucked-in air and a sufficiently high acceleration can be imparted to the "material" as a whole which is to be conveyed. 2.3. Conveying devices (24) of this type can be employed on self-propelled choppers in agriculture. <IMAGE>
