Patent DE-4220986-A1 (DE)
Inventor: MAHLICH GOTTHARD DIPL ING
IPC: A47J43/12
Filed: 1992-06-26
Abstract: A device for preparing milk froth for cappuccino (milky coffee beverage) is described, which is to be used as an additional apparatus for coffee, espresso or steam-preparing appliances equipped with a hot-steam generator and a steam pipe. In this case, a Venturi tube (3) is arranged at the outlet end of the steam pipe (1), to which Venturi tube an air intake line (5) and a milk intake line (6) are assigned in such a way that the outlet aperture (8) of the air intake line (5) and the outlet aperture (9) of the milk intake line (6) open out into the Venturi tube (3) in the zone of the greatest negative pressure. By means of the negative pressure produced by the flowing steam in the Venturi tube (3), air and milk are sucked in and mixed with the hot steam in the diffusion path (4) of the Venturi tube (3). The threefold mixture, steam/air/milk, necessary for producing the milk froth is thus already produced in the Venturi tube (3), and the desired milk froth is produced at the outlet (17) of the Venturi tube (3). The device according to the invention is distinguished by the fact that, compared to frothing aids according to the prior art, it achieves optimum frothing results even in conjunction with steam generators of low power. <IMAGE>

Title: Planishing hammer with two heads - consists of two half shells bolted together each with inward projecting circular rib to fit in grooves in two hammer heads
Inventor: HABERSTROH HARDY
IPC: B25D1/02
Filed: 1992-07-04
Abstract: The body of the hammer is formed by the two half shells which, when bolted together (4) make two sockets to receive the hammer heads (2), and a third socket at right angles to the other two to fit on the end of the handle. The shells have a circular inward projecting rib (11) in the recess (8) which fit in corresponding circular grooves (10) in the hammer heads to secure them. The hammer heads have an axial projecting conical ring surface (7) between the striker head and the groove, and this fits into the splayed inner surface of the shells. USE/ADVANTAGE - The interchangeable heads of the hammer cannot become inadvertently loose to cause an accident.
Patent DE-4222391-A1 (DE)
Inventor: ZIMMERMANN ACHIM DIPL ING
IPC: F23R3/54
Filed: 1992-07-08
Abstract: The invention relates to a cylindrical combustion chamber housing of a gas turbine, in which the compressor air is supplied through a lateral admission elbow (2) in an arc-shape to the lower conical part of the combustion chamber housing, the perforated cone (5). Connected directly to the admission elbow (2) is the inlet core (1), in which the compressor air is guided around the perforated cone (5) on both sides. By means of the arrangement according to the invention, a tangential flow about a cone is transformed into an axial flow through the bores (7) in the perforated cone (5). The transformation of the flow direction of the compressor air is supported by radially arranged ribs (3). As a result, an optimum cooling of the entire mixer pipe (6) is achieved, with minimisation of the pressure loss in the air supply region (1, 2 and 5) and a simultaneous increase in efficiency of the gas turbine. <IMAGE>

Patent DE-4228642-A1 (DE)
Inventor: RUCHHOLTZ CARSTEN DR
IPC: H01F3/14
Filed: 1992-08-28
Abstract: The invention relates to a choke coil, the impedance of which can be matched within certain limits to a predetermined impedance, and a process for setting the impedance of the choke coil of the invention. The choke coil of the invention can be used, for instance, in fluorescent lamp ballasts. The core stack of the choke coil is constructed in layers with each layer made up of two C-shaped and one I-shaped lamination. The ends of the C-shaped lamination are in opposite pairs and bonded together on one side. The ends of the C-shaped laminations opposite the bonded ends have a stop device which ensures that, after these ends have been pressed together, they are at a fixed distance apart determined by the compressive force. The impedance of the choke coil can be matched to a predetermined value by pressing the C-shaped laminations of the core stack together.
