Title: Arrangement consisting of a printed circuit board, a hybrid and a holder
Inventor: BACHOR BERNHARD
IPC: H05K3/36
Filed: 1981-11-25
Abstract: An arrangement is proposed which consists of a printed circuit board (10), a thin-film or thick-film board (11) and a holder (12), and in the case of which the holder (12) consists of plastic and the thin-film or thick-film board (11) may consist of glass or ceramic. The thin-film or thick-film board (11) is in this case constructed at least approximately in a rectangular shape and is provided on one of its side edges with electrical connecting conductors (13) which are used for the external connection of electrical circuit elements (14) which are located on it and are fitted on one of the two sides of its surface. The connecting conductors (13) project laterally from this side edge and are soldered to associated conductor tracks on the printed circuit board (10). The relevant side edge of the thin-film or thick-film board (11) in this case runs at least approximately parallel to the printed circuit board surface, at a short-distance from the printed circuit board (10). The holder (12) is attached to the printed circuit board (10) by means of plug-in pins and protects the electrical circuit elements (14) and conductor tracks (24) fitted to the thin-film or thick-film board against damage, while at the same time holding the thin-film or thick-film board (11) in a plane which runs at least approximately at right angles to the surface of the printed circuit board. The holder (12) engages around the thin-film or thick-film board (11) from its surface side which is fitted (populated) with circuit elements (14) along its two side edges, which project from the printed circuit board (10), like tongs.   <IMAGE>
Patent DE-3148930-A1 (DE)
Title: Device for separating foods
Inventor: RIENKS GERD
IPC: B26D1/46
Filed: 1981-12-10
Abstract: The present invention relates to a meat-cutting or sawing device and aims to achieve clean cut surfaces without limitation of the maximum length of the product to be cut. To this end, the invention proposes that, in the event of use of a continuous separating band, this is guided forwards and backwards immediately adjacently in the separating zone. The separating band is preferably guided in a tension-free manner at both ends of the separating zone. Because of the directly adjacent nature of the forward and backward running separating band, the transverse forces with regard to the product to be cut are virtually eliminated, so that the meat is not tumbled.
Patent DE-3206187-A1 (DE)
Title: Starting device
Inventor: DUE JENSEN NIELS
IPC: H02P1/44
Filed: 1982-02-20
Abstract: A starting device for a single-phase asynchronous motor having a main winding and an auxiliary winding which is displaced approximately 90 DEG  with respect thereto, having a capacitor and a contact device for mass production. According to the invention, the contact device is set up to decouple the capacitor as quickly as possible, under all circumstances, once the motor has been set in motion. In consequence, the life of the capacitor is increased. A coincidence circuit can be advantageously set up in order to control the coupling/decoupling as a function of at least two parameter values. One advantage in the case of such a coincidence circuit is that it is possible to modify the starting device easily to match the desired application. In certain cases one is interested in, for example, pure temperature control and, in other cases, in a conditional temperature control, i.e. a temperature control which does not come into action until a certain time has elapsed. Alternatively, one may be interested in pure time control, for example intermittent operation, the one input of the coincidence circuit assuming a fixed value and the other input being coupled to a time keeper, which may be periodic.

Title: Method for determining a desired value of a temperature or pressure controller of a heat pump
Inventor: KANTNER ALEXANDER DR
IPC: F25B49/04
Filed: 1982-03-12
Abstract: The present invention relates to the method for determining the desired value of a temperature or pressure controller of an absorption heat pump. The climatic zone of the location at which the heat pump is set up and the maximum external temperature up to which heating is still to be performed are essential of such a controller. The minimum temperature at the installation site of the heat pump and the maximum external temperature up to which heating is to be performed represent end points of curves, so that specific flow temperature values can be assigned to temperatures located therebetween. These flow temperature values are assigned values for the solvent and fuel throughputs, to be precise in accordance with the relationship <IMAGE> VRV signifying the gas throughput, VRVmin the minimum gas throughput, A a constant, N the operating capacity and Nmin the output at the point from which the burner is no longer continuously regulated, zeta  VRVmin the thermal ratio for the corresponding capacity Nmin, and  zeta  VRV all the thermal ratios from Nmin to Nmax.

Title: Urethral catheter with swellable body
Inventor: PFEIFFER HANS
IPC: A61M29/02
Filed: 1982-06-08
Abstract: In cases of urethral stricture it has hitherto been usual initially to insert a thin catheter into the urethra and to replace this after some time with a thicker one, and so on. This process was repeated several times and lasted days to weeks. Constantly changing the catheters with ever increasing diameter was uncomfortable or even painful for the patient. The invention makes this repeated procedure unnecessary. There is now only one catheter surrounded by a swellable body filled with liquid. The requisite expansion is achieved by metered addition of the contents.

Title: Bearing for the axial and radial bearing of a rotor having a large radial extent
Inventor: AUER WERNER DR ING
IPC: F16C39/06
Filed: 1982-11-25
Abstract: A bearing is described which, in the case of a rotor 1 having a large radial extent, stabilises said rotor about the tilting axes. To this end, in the outer region, the rotor 1 has two semicircular permanent ring pairs or ring elements 6, 7; 8, 9 which are in each case radially magnetised in opposite directions. Located in the air gap between the permanent magnet rings is an annular coil 18 which is supplied with an alternating current whose frequency corresponds to the speed of the rotor. The phase angle of the current in this case corresponds to the phase angle of the magnetic field, so that tilting moments and nutation of the rotor 1 are effectively damped. The axial and radial bearing can be implemented as shown, using an electrodynamic magnetic bearing 25, but may also be implemented using a mechanical bearing. <IMAGE>

Title: Energy-saving cooking vessel for use on an open flame
Inventor: NUSSER ALBAN
IPC: A47J36/36
Filed: 1983-03-25
Abstract: An energy-saving cooking vessel for use on an open flame, having an outer vessel which surrounds the combustion gases, wherein an opening in its bottom terminates with the gas burner or the burner head of a vaporising burner in such a way that not substantially more than the amount of combustion air necessary for complete combustion can reach the flame. The annular and bottom space enclosed between the cooking vessel and the outer vessel are of such confined construction that the combustion gases eddy. The outer vessel is of heat-insulating construction, whereas the cooking vessel is composed of material with good heat-conducting characteristics and has on its outer side a lamella surface and/or heat exchanging ribs. The energy-saving cooking vessel can be taken apart for cleaning purposes. For reasons of saving weight and improved transportability, for mobile use, the outer vessel is formed by multi-layer, flexible and heat-resistant fabric which is stretched removably over a frame which can be plugged together with removable, firmly hooked-in support legs. After separation at a separation point, the outer vessel can be spread flat for easier transportation. <IMAGE>

Title: Web-fed rotary printing machine
Inventor: BEZLER WILHELM DIPL ING
IPC: B41F33/02
Filed: 1983-05-19
Abstract: In a web-fed rotary printing machine having the usual assemblies, the main drive motors thereof are assigned a regulating and control device which ensures synchronous running of said motors and a high degree of constancy of the adjustable rotary speed. Said device comprises a frequency standard of high frequency constancy with means for providing a variable and very precisely adjustable output frequency which serves all the main drive motors simultaneously as a reference frequency for adjusting the desired reference rotary speed. Additionally, for each main drive motor, the regulating and control device comprises a rotary pulse generator for recording the actual value of the rotary speed, which pulse generator is arranged on a rotating part which lies in the force-transmission path between the main drive motor and the site of the introduction of force into the web of material to be transported. For each main drive motor, the regulating and control device also has an electronic evaluating device in which the pulses of the reference frequency of the reference rotary speed and of the signalled frequency of the actual rotary speed are counted by counters and compared with one another in a comparator by addition or subtraction and, if the actual state deviates from the reference state, appropriate readjustment commands are transmitted to adjust the main drive motor to the reference rotary speed.
