Title: Panel-type heater
Inventor: GROEBE KATHLEN
IPC: F24D13/02
Filed: 1993-03-16
Abstract: The invention relates to an electric panel-type heater having a front plate made from natural or artificial stone for use as a decorative heat source for living rooms and business premises. The panel-type heater according to the invention consists of a box-shaped heater housing (4) whose cover is constructed from a front plate (1) made from natural or artificial stone. Arranged in the heater housing (4) is a panel-type heating element (3) which bears against the front plate (1) made from natural or artificial stone and which is supplied with electric current via electric plug-in or sliding contacts (9; 11) located thereon and in the heater housing. It is advantageous in this case that the heater can be manipulated (handled) very simply, i.e. is easy to transport, to mount, to assemble, to repair and to service. By avoiding bores or notches in the front plate made from natural or artificial stone, the danger of material stress cracks in said plate is minimised. The heater body (4), which bears tightly against the wall of a building, causes only slight convection, as a result of which discoloration and soiling of this building wall are largely avoided. <IMAGE>

Title: Continuous-flow water heater (instantaneous water heater) and method for manufacturing the heat exchanger of the continuous-flow water heater
Inventor: KLIEBA HANS
IPC: F24H1/14
Filed: 1993-03-27
Abstract: Gas-fired continuous-flow water heaters possess as heat exchanger a combustion chamber having a lamellar block in which a plurality of oval tubes for carrying the water are arranged. On account of the oval tubes, the manufacture of the lamellar block is however very time-consuming, particularly as far as the connection of the individual tubes to one another outside the lamellar block is concerned. As a result of the oval cross-section of the tubes, the connection pieces must likewise have an oval cross-section at their ends. The manufacture of accurate-fitting connection pieces is very laborious and requires special machinery. To solve this, there is proposed a continuous-flow water heater in which the oval tubes (3) have a circular cross-section at the ends outside the lamellar block (1) and are connected by appropriately fitting shaped pieces (7). In the working method according to the invention, the prefabricated heat-exchanger assembly is   - placed with the bottom side of the lamellae on a mounting plate in a tube end forming machine, the rear edge of the tube bends is pressed against a stop and the rear longitudinal edge of the prefabricated assembly is pressed against a stop, - the prefabricated assembly is secured by means of clamping means acting on the top edge of the lamellae, - the oval ends of the tubes are formed into a circular cross-section by rounding tools in the form of mandrels and a draw-in ring and   - the re-rounded ends are... with...

Title: Keys and tumblers for multi-locking systems
Inventor: GOLUB DANIJEL
IPC: E05B19/00
Filed: 1993-04-21
Abstract: Tumblers and keys for multi-locking systems are, in general terms, suitable for locks having mechanical tumblers of any type. In particular, multi-locking systems are to be employed when there is a diversification of the individual lockings, and there is therefore a possibility of incorporating the existing locks into a locking system. With the diversification of individual lockings by means of the binary coding in the overall coding triangle and of the system construction of the overall coding triangle, it becomes desirable for the features affording an increase in the tumblers to provide forward-thinking ideas. My belief in the construction of the multi-locking system enables me confidently to hope that the multi-locking system, including the keys and tumblers, will entail effects which look to the future.

Title: Hot strip rolling train control - comprising setting roller surface speeds in neighbouring stand pairs to cancel out internal mass flow variations
Inventor: SERIGUCHI KUNIO
IPC: B21B37/26
Filed: 1993-07-01
Abstract: To control a hot strip rolling train, the roller gap is set so that the delivery thickness matches a reference value at each stand. An internal stand mass flow variation is computed or used at the delivery side of an upstream stand and the entry side of a downstream stand in a pair of neighbouring stands. The surface roller speed of the upstream stand is controlled to zero the internal mass flow variation. The drive of a slip motor is controlled so that the registered motor angle matches a given reference angle to the junction between the preceding bar and the next bar at a position exactly in front of the upstream stand and after passage through the downstream stand, with simultaneous measurement of the tension of the rolled material using a loading from the slip, and the roller surface speed is set at the upstream stand so that the tension matches a reference tension during balanced rolling. The slip drive motor speed is controlled for a slip roller to match a reference angle by an amount so that the rolled material is not contacted as far as the junction through the downstream stand after the junction point as reached the exact position in front of the upstream stand. USE/ADVANTAGE - The method is for the control of a hot strip rolling train to give a stable and floating thickness change with a number of stands, where the material is joined to give a continuous action.

Title: Three-high rolling stand without a housing
Inventor: EVERS RUDOLF
IPC: B21B31/24
Filed: 1993-06-30
Abstract: The problem underlying the invention is to provide a screw-down mechanism for the rolls of a three-high rolling stand in which the top and bottom rolls are screwed down independently of one another by a drive arranged outside that part of the rolling stand which is most subject to scale and water. According to the invention, the problem is solved by providing a single drive in the form of a screw-down gear (8) above the rolls (1; 2; 3) and by making the required tie (7) in two parts, the upper parts (16) of the tie which are assigned to the upper and central roll (3; 2) being connected directly to the screw-down gear (8) and the lower parts (14) of the tie which are assigned to the bottom and central roll (1; 2) being connected to the screw-down gear (8) through the respectively associated upper part (16) of the tie via a respective connecting element (15). The area of application of the invention is primarily in rolling mills on rolling stands for the hot rolling of metal. <IMAGE>

Title: Method for producing undephased measurement signals in the case of passive receivers with nonideal impedances
Inventor: HORN KLAUS PROF DR ING
IPC: G01D5/243
Filed: 1993-08-17
Abstract: Known measurement circuits - in the case of high accuracy requirements, mostly in the form of carrier-frequency measurement bridges - for producing measurement signals from the changes, dependent on the measured quantities, of capacitive, inductive or ohmic impedances of passive receivers all have the disadvantage that the measurement signals which they output are not strictly shifted by +/-  pi /2 or by 0 with respect to the supply voltage phase, because parasitic active impedances (losses) or reactive impedances and line capacitances lead in complex ways to phase rotations. Downstream signal evaluation is then, even in the case of high-performance phase selectivity, no longer able to make a clear-cut distinction between useful and interference changes in the receiver signals. The features according to the invention are intended to avoid these disadvantages.   Evaluation of the short-circuit current signal instead of the open-circuit signal in the case of preferably capacitive and ohmic sensor bridge circuits, in conjunction with symmetrical secondary windings of a voltage converter, as well as, in the case of preferably inductive sensor bridge circuits, supplying each sensor partial impedance via an individual current converter, primary-side series connection of these current converters and evaluation of the difference in the voltage drops across the associated lossy inductive sensor partial impedances. <IMAGE>
