Title: Design of building such that they are secure with respect to earthquakes, by using a pendulum mounting
Inventor: GALLASCH HUBERT DIPL ING
IPC: E04H9/02
Filed: 1988-06-09
Abstract: Earthquakes effect displacements (d) in the ground. These give rise to horizontal forces (H) depending on the dimensions of the mounting, i.e. on the height (D) of the supporting body and the radius ( sigma ) of the ball sockets. The horizontal forces try to displace the building. The force of inertia ( theta ) of the building counteracts this. The value for the force of inertia taken in calculations must be the lowest natural frequency (f) of the building since this gives the most unfavourable value which, at any rate, is to be greater than the displacement force (H). Earthquakes of greater intensity, i.e. of greater frequency, effect an increase in the force of inertia, thus helping to secure the freedom from vibrations. Since, due to the pendulum movements, the horizontal vibrations are no longer transmitted onto the building, the building is secure with respect to earthquakes and no longer needs to be designed for earthquakes. It should be mentioned that, by virtue of the ball-socket type mounting of the supporting body, the latter always returns into its original vertical stable position.
Patent DE-3823032-A1 (DE)
Title: Bottle treatment system and control method therefor
Inventor: ACHHAMMER KARL-HEINZ
IPC: B65B57/08
Filed: 1988-07-07
Abstract: In the case of a bottle treatment system having a first treatment machine, preferably a filling machine; a second treatment machine, preferably a labelling machine; a conveyor belt for conveying bottles from the first treatment machine to the second one; and a bottle stop which is arranged upstream of the first treatment machine is intended to provide the possibility of immediately switching off the labelling machine in the event of malfunctions occurring within it, without simultaneous switching off of the filling machine being necessary. This is achieved in that an additional conveyor belt is assigned to the conveyor belt and a deflection device is arranged on the upstream ends of both belts in order, when the labelling machine is switched off, to deflect the bottles delivered by the still running filling machine onto the additional conveyor belt, after which process the filling machine is switched off and the bottles are stored on the additional conveyor belt while the malfunction persists.

Title: Rail bearing
Inventor: SPINDLER HEINZ
IPC: E01B9/60
Filed: 1988-10-08
Abstract: The invention relates to a rail bearing, consisting of angular clamping plates, a rail support, which is screwed to the clamping plates directly or indirectly (i.e. via an intermediate part), and an insulating element made of rubber or rubber-like material which is situated between rail foot, rail web, clamping plates and rail support. The essential feature of this invention consists in that the insulating element is designed, in the transverse direction of the rail, continuously and in one piece (variant A) or continuously and in three pieces, the two insulating-element parts between rail web and clamping plates exhibiting greater hardness than the insulating-element part between rail foot and rail support (variant B).
Patent DE-3835259-A1 (DE)
Title: Circuit arrangement for receiving serially transmitted digital data
Inventor: MAIER KLAUS DIPL ING
IPC: H04L7/033
Filed: 1988-10-15
Abstract: The object is to be able to use a control clock which is asynchronous to the data stream in the reception of data arriving serially. The incoming data bits are sampled with a sampling and counting clock, which is asynchronous to the data stream, at an approximately integral multiple of the bit rate but at least three times, and transferred into a shift register. The outputs of the shift register are connected to an evaluating logic which influences a counter controlled by the same clock, with the same number of counting steps as there are stages in the shift register, in such a manner that a control clock appears at one of its outputs. This is used for clocking a D-type flip flop which accepts the data from another output of the evaluating logic. Due to the asynchronous sampling and counting clock, no phase detector circuits are necessary and no high requirements for the frequency accuracy of the clock generator are necessary. The entire circuit arrangement can be combined in one integrated circuit so that the higher frequencies do not appear at the inputs and outputs of this circuit.

Title: Linear motor drive for sheet guiding elements
Inventor: WAGNER BURKHARD
IPC: B65H43/00
Filed: 1988-12-03
Abstract: The linear motor drive for sheet guiding elements is applied in sheet processing machines. The sheet control of the sheet guiding elements (16) is implemented by detecting the sheet position with the aid of a transmitter (6) which is positioned along the sheet run section of the folding pocket (4) and transmits a corresponding signal to an electronic control device (8). The required information on the machine speed is transferred by a transmitter (17) to the electronic control device (8), which takes said information directly from a folding roller (18). The linear motor (11) which drives the sheet guiding element (16) is triggered by the control device (8) via an amplifier complex (12). The control device (8) is provided with a display (10) and an input keyboard (9). Feedback required for exact control is ensured by a wound encoder (14) assigned to the linear motor (11) as a detector. A swivelling lever (26) pivoted to the carrier (25) of the sheet guiding elements is provided for the purpose of guiding in the correct track the sheet guiding element (16) which is coupled to the secondary part (13) of the linear motor (11). <IMAGE>

Patent DE-3907202-A1 (DE)
Title: Pressure sensor
Inventor: HAEFNER HANS W
IPC: B28B1/00
Filed: 1989-03-07
Abstract: For the simple production of a pressure sensor having high measuring accuracy, it is proposed to form the ceramic diaphragm and the ceramic base for clamping the pressure sensor from a sensor body moulded together in one piece, the clamping position being spaced off from the diaphragm by means of the interposition of flexible transitions, to avoid tensions. In a production method for a pressure sensor of this type, the diaphragm and the base having the clamping position are formed in one operation before firing to form a homogeneous sensor body. Of particular advantage is the design of a connection thread in the sensor body itself, since by this means separate connection housings are dispensed with.

Title: Sheet-metal facing element
Inventor: HEINEMANN HERBERT
IPC: E04C2/292
Filed: 1989-03-13
Abstract: A sheet-metal facing element for cladding building walls has an outer side 1, parallel longitudinal borders 2 and 3 which are bent off inwards from said outer side, and a porous insulating composition 4 on the rear side. In order that such a facing element can be mounted on a wall 10 without a substructure, provision has to be made of a venting means in order to channel away any moisture which may be discharged from the wall 10 and to prevent condensation. For this purpose, provision is made for tubes 5 which extend parallel with respect to the longitudinal borders 2, 3 and are fully embedded in the insulating composition 4. These tubes 5 form ventilation ducts. The wall of the tubes 5 is permeable with respect to water vapour. Moisture which is discharged from the wall 10 can thus diffuse through the pores of the insulating composition 4 and the walls 6 and be channelled away by the air flowing within the tube 5. <IMAGE>
Patent DE-3909365-A1 (DE)
Inventor: NGHIEM LUONG DR
IPC: A21B1/28
Filed: 1989-03-22
Abstract: A baker's oven with at least one baking space (2, 3, 4), which has a lower bottom (6) and an upper radiation plate (5), is provided with heating ducts (8) surrounding the respective baking space (2, 3, 4) and a burner (13) for heating the heating gases. In order, with low constructional outlay, to make possible a baking space temperature characteristic which is optimal for different products to be baked, the baker's oven is assigned a control device (24) which switches the burner (13) on or off according to at least one measured temperature value, representing at least one actual temperature in at least one baking space (2, 3, 4), of a temperature measuring point (25), along a continuous temperature-setpoint characteristic over the baking time. It is thus possible in particular to operate a baker's oven with heating-gas circulation, which is normally designed as a multi-level oven and has only a low heat- storage capacity, with actual-temperature characteristics in the baking space(s), which correspond to those of so-called stone ovens. <IMAGE>
