Patent DE-4243994-A1 (DE)
Title: Electric toaster
Inventor: FRAUNHOFER ALFRED DIPL ING
IPC: A47J37/08
Filed: 1992-12-23
Abstract: The electric toaster has a top-loading chamber for the bread and heaters (80, 82) at the sides with protective grills. The cradle (40, 42) for the slice of bread lies between them, and is moved upwards to receive a new slice or deliver a toasted one, but downwards for the toasting operation. For toasting, at least one of the heaters is tilted about a horizontal axis (76, 78) in towards the bread. This action is caused by the downward movement of the cradle (with bread slice) pushing against the inclined lower face of the heater. There is a spring between the two tilting heaters to keep them together.

Title: White light transmission hologram production e.g. for cheque card
Inventor: MIRAU VOLKER
IPC: G07F7/08
Filed: 1993-01-19
Abstract: The white light transmission hologram has stored information that is not visible to the human eye and can only be viewed with monochromatic coherent light. As a first stage in the manufacture of the hologram, a master hologram (1) is produced. This is used to produce copies onto a hologram plate using a laser as a white light source. This allows additional information such as a bar code to be produced. The bar code is reproduced using monochromatic light and can be evaluated by a photocell matrix.
Patent DE-4304505-A1 (DE)

IPC: A61F13/22
Filed: 1993-02-15
Abstract: A digital tampon (20) for feminine hygiene, having a round dome (33) and a recovery tape (24), consists of a blank which is shaped by winding up a length of continuous random fibre web and which is pressed to produce a preform having a fibre core, longitudinal ribs and longitudinal grooves. The longitudinal ribs are subsequently lightly pressed to the final shape of the tampon (20; 28). The preform, before being pressed to the final shape of the tampon (20), is shaped as a result of the separate, but simultaneous radial pressing of directly adjacent sectors of its entire circumferential surface to form a longitudinal groove and a longitudinal rib respectively on each sector of the circumferential surface. The fibre material is pressed radially to a lesser extent in the region of the end (22) provided with the recovery tape (24). The invention also relates to an apparatus for producing the tampon. <IMAGE>

Title: Bearing of a running wheel
Inventor: OSTERMEIER HEINRICH DIPL ING
IPC: F16C33/62
Filed: 1993-02-22
Abstract: The invention relates to the bearing of a running wheel 4, in particular for agricultural or horticultural machinery, e.g. a lawnmower 1. The housing 2 of the said machinery can be moved on the floor by means of a plurality of running wheels 4.

In order to improve the service life of such a bearing, there is provision for the outer ring 16 and the inner ring 17 of the two angular contact ball bearings 7 to be produced from plastic and for the balls in the raceways to be arranged directly adjoining one another so that they form a complete circle. The balls consist of steel. <IMAGE>
Patent DE-4308759-A1 (DE)
Inventor: KREMER ROBERT
IPC: F24D3/08
Filed: 1993-03-19
Abstract: In order to increase the thermal efficiency of a three-pass boiler which is used for combined heating of a domestic hot water accumulator and a building heating system, it is proposed to surround the second and third pass with a first water space (5) having a comparatively low water volume. The first water space (5) is at least partly separated from a second water space (7) by a boundary surface (8). Whereas the heating of the water in the first water space (5) via heat-exchanger surfaces takes place directly by means of the hot waste gases, the second water space (7) is heated via the boundary surface (8) indirectly and by means of gravity circulation. The first water space serves solely to heat the accumulator, whereas the second water space has the connections for the heating-system circuit. The connection piece (9) for the flow of the accumulator circuit is situated at the highest point of the boiler and the return connection (10) at the lowest point of the first water space (5). At the same time, the water spaces (5, 7) are interconnected in this region, so that a normal gravity-flow operation of the boiler is possible. On the other hand, when a feed pump for the accumulator circuit is switched on, the gravity flow is cut off. <IMAGE>

Title: Method and kit for the positionally correct transfer of a jaw model into an articulator
Inventor: SCHREIBER HANS DR DR
IPC: A61C11/00
Filed: 1993-05-26
Abstract: The invention presents a method and a device in which an exchangeable bite plane (1), which in the version depicted is extended by a negative spherical cap (3), makes it possible to produce the connection to the actual facebow (6, 7, 8, 22, ...) via a ball (15)/pin (16) mechanism. A glabellar support and corresponding marking elements have not been depicted. However, it is worth mentioning that in this version the ball (15) is provided with longitudinal and latitudinal angle marks and that both the position and the length of all displaceable elements can be read off in a defined way. Data transfer to the laboratory takes place subsequently by passing on the bite plane (1). <IMAGE>
Patent DE-4317600-A1 (DE)
Inventor: HEINRICH ULRICH
IPC: A61B5/022
Filed: 1993-05-27
Abstract: The compression apparatus is intended for creating a bloodless condition in the extremities during surgical interventions or for intravenous local anaesthesia with the aid of a compression cuff that can be applied to the extremities and can be exposed to a pressure medium. A controllable pressure control valve (4) for the pressure medium is used to adjust the compression pressure in the compression cuff. The blood pressure value measured continuously by an automatic blood pressure instrument (12) causes a blood pressure-dependent control signal for the pressure control valve (4) in a control unit (14), so that the compression pressure in the compression cuff changes correspondingly when the blood pressure value changes. <IMAGE>

Title: Device for displaying a desired position which has been reached by electrically conductive workpieces at stops, in particular on roller tracks (roller conveyors)
Inventor: HENKE HANS-GEORG
IPC: B65G47/88
Filed: 1993-09-09
Abstract: When guiding workpieces up to stops, the following problems can arise:     - the workpiece rebounds from the stop.   - a damping spring remains tensioned.   - the stop is displaced by an excessively strong impact.   In order to indicate that none of these problems which lead to positional errors has occurred, an electrical display is connected on the one hand, via a current source, to the roller track and the metallic workpiece located thereupon, and on the other hand to a switching contact which is located on a base body. This switching contact is connected via a cable to a contact a, which is fastened rigidly in the longitudinal direction to the base body and has pressed against it by a spring a contact b which is connected in an electrically conductive and mechanically firm fashion to a stop plate. The contact a, contact b and stop plate are arranged in a fashion electrically insulated from the base body.

Title: Balance weights which can be fastened by electric resistance spot welding to a rotor to be balanced
Inventor: HOFER HERMANN DIPL ING
IPC: F16F15/34
Filed: 1993-09-21
Abstract: Balance weights are described which are fastened by electric resistance spot welding to a rotor to be balanced. The balance weights are designed in such a way that the cross-sectional lines of the material strip form at its ends semicircles which are convex to the outside and concentric with the end weld-on points and the diameters of which approximately correspond to the width of the material strips. The space requirement for spot-welded balance weights is thereby reduced, an additional test or pressing-on operation is dispensed with, and there is no longer a risk of injury from the otherwise arched, angular ends of the balance weights.

Inventor: HAYAKAWA YUZO
IPC: B29C70/50
Filed: 1993-11-22
Abstract: Equipment for curing sheet moulding material has at least one pair of forming tools along the direction of travel of the material; the gap between these tools is used to heat the basically semi-cured sheeting which passes through the gap after being suitably formed.

Typically, the sheeting (6) passes between the lower rollers (1) and upper forming rollers (2). These pass the sheeting to the curing station (10). Here the entrance (21) matches the cross-section of the sheeting before first (Z1), second (Z2) and third (Z3) curing zones. The entrance (21) however leaves some gap round the sheet which has a rectangular profile.
