Title: Fold-away bed (Murphy bed)
IPC: A47C17/52
Filed: 1993-07-16
Abstract: In order to provide a fold-away bed having a cabinet carcass in which the bed is mounted in such a way that it can be swung about a horizontal axis, having a bed frame, a fittings frame supporting the latter, a cabinet front wall fixed externally thereto, a floor support capable of being swung out being arranged on the fittings frame, in the case of which fold-away bed the pivot point for the fittings frame is largely in the proximity of the standing plane of the fold-away bed and the lying area is at a distance from the standing plane promoting comfort, it is proposed that the bed frame (3) is connected pivotably (at 8) at its free end to the fittings frame (5), the carcass-side pivot joint (2) is constructed in the vicinity of the bottom of the cabinet carcass (1) and there is arranged on the carcass (1) a support (9) lying above the pivot axis (2) of the fittings frame (5), the distance of which from the pivot axis (2) corresponds to the desired distance of a supporting point of the bed frame (3) from the surface on which the fold-away bed is placed and on which the carcass-side end of the bed frame (3) is supported in such a way that when the bed has been swung into the cabinet carcass (1) the bed frame (3) runs in a manner directed parallel to the fittings frame (5), and when the bed has been swung out of the cabinet carcass (1) the end of the bed frame (3) is supported on the support (9). <IMAGE>

Title: Turntable which is mounted in a floating manner
Inventor: WEBER FRANZ
IPC: E04H6/40
Filed: 1993-07-20
Abstract: The invention relates to a turntable which is mounted in a floating manner, is positioned vertically and horizontally with low friction, receives weights, preferably a motor vehicle, does not require a drive, as a result of the low friction, and can be rotated by hand even in the case of large weights. The system is simple and inexpensive.
Patent DE-4326389-A1 (DE)
Title: Hydraulic pump
Inventor: BECK ERHARD
IPC: F04B53/10
Filed: 1993-08-06
Abstract: The object of the present invention is to create a pump which also has good suction behaviour at the top dead centre of the delivery plunger (31). To this end, an arrangement of lifting elements is proposed which are contained in a transmission element (41) and serve at the top dead centre of the delivery plunger (31) to compress the valve spring (43). The opening pressure of the suction valve or valves (33, 34) at the top dead centre of the delivery plunger (31) is thereby reduced. A volumetric flow into the pressure chamber (36) can thus take place immediately when the delivery plunger (31) is set in motion towards its bottom dead centre. Thus the full pressure which arises on the suction side can be utilised for accelerating the pressure medium without losses due to valve admission pressures. <IMAGE>
Patent DE-4335331-A1 (DE)
Inventor: NEUBURGER BRUNO
IPC: B28C5/12
Filed: 1993-10-18
Abstract: The invention relates to a device for continuously mixing powdery or fine-grained building materials with water and for transporting the wet mixture. The device has an elongated, horizontally orientated continuous mixer (10), which can be attached to a silo (14) for building materials, and an elongated mixture pump (20) having an inlet chamber (50), which can be attached to a mixture outlet (18) of the continuous mixer (10), and a pumping zone (58), in which arrangement there passes through both the continuous mixer (10) and the mixture pump (20) in their longitudinal extent (48) in each case a motor-actuated drive shaft, each bearing transporting and/or mixing tools. According to the invention, the mixture pump (20) is orientated in its longitudinal extent (48) transversely to the longitudinal extent (40) of the continuous mixer (10) with pumping zone (58) tilted down at an angle, the angle of tilt being less than 45 DEG  relative to the horizontal (26), and the inlet chamber (50), through which the relevant drive shaft (48) passes, of the mixture pump (20) having a base (68) correspondingly tilted towards the pumping zone (58). <IMAGE>

Title: Planar spring element
Inventor: LANTZSCH HANS
IPC: A47C23/00
Filed: 1993-11-06
Abstract: In the case of a bed frame having a plurality of spring elements over the surface of the bed frame, a solution is to be provided with which a greater degree of lying comfort, individual adjustment and at the same time adjustability, e.g. of the head and foot part, is made possible by simple means. This is achieved by the spring elements being designed as individually mounted spring bodies (5) and being arranged close together to form the supporting surface (6). <IMAGE>

Title: Preventing efflorescence on mineral substrates, esp. roof tiles - by treating surface with aq. prepn. based on a polymer contg. chemically bonded hydrolysable organo:silane deriv.
Inventor: BECHERT BERTOLD
IPC: C08G63/695
Filed: 1993-12-03
Abstract: A process for preventing efflorescence on mineral substrates (I) comprises treating the surface of (I) with an aq. prepn. contg., as principal component, an aq. dispersion of a polymer (II) contg. 0.1-5 wt.% chemically-bonded organo-Si cpd. (III) which forms a silanol by hydrolysis. Pref., (II) is prepd. by emulsion polymerisation of a mixt. of 95-99.5 wt.% n-butyl or 2-ethylhexyl acrylate, ethyl or methyl methacrylate and/or styrene (at least 2 of these monomers) and 0.5-5 wt.% (meth)acrylic acid, (meth)acrylamide or vinylsulphonic acid, in the presence of (III), esp. e.g. vinyltrimethoxysilane, gamma-methacryloxypropyl- trimethoxysilane, 3-mercaptopropyl- trimethoxysilane, gamma-glycidoxypropyl- trimethoxysilane (IIIA). USE/ADVANTAGE - Used esp. for preventing efflorescence on concrete roof tiles, bricks, etc.. The process provides a highly weather-resistant coating which affords excellent protection against lime efflorescence; the coating does not become sticky at elevated temp. and therefore does not attract dirt in hot weather.

Title: Ammonia chemiluminescence reaction for detection of urine in reusable bottles and containers
Inventor: HEIDRICH KARL DR
IPC: G01N31/22
Filed: 1994-06-05
Abstract: The invention relates to a method for determining ammonia by a chemiluminescence reaction of ammonia with fluorine. The advantage over the prior art resides in the fact that the otherwise required conversion of ammonia into nitrogen monoxide before the chemiluminescence reaction with ozone can be left out and the emission spectrum can be shifted fully into the visible range from the infrared and can thereby be detected by a photomultiplier.
Patent DE-4433749-A1 (DE)
Inventor: SCHUBERT HEINZ
IPC: B29C48/13
Filed: 1994-09-22
Abstract: A process and device are proposed for applying a plastic strand (35) as a spacer with a pre-determined desired thickness (D) to a glass pane (33) with a view to producing insulating glazing units. This involves the use of a nozzle (17) which moves along the edge of the pane (33) and as it does so deposits the strand (35) extruded from the nozzle (17) onto the pane (33) in such a way that the beginning and end of the strand meet. The thickness of the strand (35) extruded from the nozzle (17) is increased at the beginning along a predetermined length (L) from zero to the desired thickness (D), and accordingly reduced at the end of the strand (35) along the same path from the desired thickness (D) back to zero.

Patent DE-4447443-A1 (DE)
Inventor: FUJIO TADAKAZU
IPC: A47J36/06
Filed: 1994-12-28
Abstract: There is disclosed a cooking pot with a lid (1) wherein the top edge of the pot body (18) is provided with a cut-away portion (4). The part of the lid which corresponds to the cut-away region on the pot body (7) is shaped so that when both are aligned, a slot is formed in the pot such that a utensil e.g. a ladle (5) can rest in the cooking pot without the lid being raised. The slot may be wide enough to remove the ladle spoon (13) without removing the lid. The size of the slot can be increased or reduced by turning the lid. Therefore, the slot also acts as a steam vent. The ladle can be prevented from falling into the pot by blocking means attached to the handle shaft. Moreover, a holder may be provided on the inside and/or outside of the pot such that the ladle shaft lies horizontally. Alternatively, the ladle shaft can be hooked over the edge of the pot. <IMAGE>
