Patent DE-19542690-A1 (DE)
Inventor: SCHOLZ GERHARD DR ING
IPC: H01H73/00
Filed: 1995-11-16
Abstract: All switching devices which have the purpose of protecting people or objects from the harmful effects of electric current include at least triggering elements which trigger the appropriate switching mechanisms whenever predetermined threshold values are exceeded. This opens the main current contacts in the switching device, thus usually stopping current flow. However, such switching devices occasionally fail in an emergency situation because, for example, the trigger elements stick, the switching mechanisms jam, the contacts become welded together, or because of other faults. For such eventualities, a device is proposed for forcibly interrupting the appropriate mains or main current lines with a work storage unit. The latter produces a force along a pathway and is kept in an inactive state by a locking mechanism. The locking mechanism can easily be released by a trigger controlled by the switching device and the work storage unit can thus be freed to switch to its active state. A separator device driven by the work storage unit then forcibly separates the current lines. The device is especially suitable for incorporation in or combination with protective switches such as fault current protective switches, automatic cut-outs, bus protection switches, motor protection switches, power protection switches and the like.

Supporting lugs (11 and 12) which project obliquely inwards are shaped on the sidewalls (4 and 5) between both funnels (8 and 9). Their resilient ends (13) extend towards each other and come to bear on the thread of the threaded bolt (10) pressed into the receiving area. Two opposite resilient tongues (15) arranged between said supporting lugs (11 and 12) project across the receiving area (3) and form with their reinforced ends (16) a small gap (s) in the middle. When the threaded bolt (10) is inserted into the receiving area (10), these resilient tongues (15) are swayed (16) before the opposite supporting strips (11 or 12) and also come to bear on the thread of the threaded bolt (10).

Patent DE-19651862-A1 (DE)
Inventor: NEUTEL ANDREAS
IPC: H05K3/30
Filed: 1996-12-13
Abstract: This invention concerns a process for reflow soldering of circuit boards fitted SMD components in which SMD components are placed on soldering surfaces of the first side of a circuit board and soldered to the circuit board in a first reflow soldering step. Subsequently the circuit board is turned with the first side underneath and SMD components are placed on soldering surfaces of the upward-facing second side, which are soldered to the circuit board in a subsequent reflow soldering step. The SMD components on the first side of the circuit board are firmly cemented to the circuit board before the second reflow soldering step on the first side. It is proposed that after the first reflow soldering step a cement be injected from the second side of the circuit board through holes which pass through the circuit board and correspond to the components soldered to the first side of the board into the space between the components and circuit board.

Title: Thermal dryer with exhaust gas cleaning, afterburning e.g. for wood chips
IPC: F26B21/04
Filed: 1996-12-23
Abstract: The dryer (1) comprises at least one additional heat exchanger as a heater (8), arranged in the heating exhaust stream before a gas-gas heat exchanger (7). On the heating side, exhaust gases are cooled by passing through the additional heat exchanger. On the cooling side, either steam is generated or a heat transfer fluid, of high volume specific heat capacity, is heated. The dryer consists of a vapour heated drying path (2) with an additional heated drying path (4). At least one more heat exchanger, as a heat register (5), provides the additional heating of the dryer and is arranged after the vapour-heated drying path. The heating side releases heat by condensing steam or cooling a heat transfer medium of high specific heat capacity. Further heat, in addition to that from the vapour, is supplied. The heater and the heat register are connected together to create a circuit (9) for the heating medium.
Patent DE-19700368-A1 (DE)
Title: Preparation of drinks, e.g. coffee, fruit tea, fruit juice etc. enriched with divalent iron
Inventor: JAKUBOWICZ LYDIA DR ING
IPC: A23L2/52
Filed: 1997-01-08
Abstract: A method for the preparation of drinks based on drinking, spring, table or mineral water, which contain divalent iron (Fe<2+>) ions, comprises dissolving a divalent (in)organic iron salt in the water part of the drink, eg. black coffee, fruit teas, drinking water/fruit juice mixture or pop, or in the water itself, to give an Fe<2+> cation concentration of 0.1-20 (preferably 2-10) mg/l.  The stability of the Fe<2+> ions in the drink is guaranteed by one of the following methods : (1) ensuring that the water (part) in which the salt is dissolved has a pH of 2-5 (3-4), or by dissolving at least one acid (preferably edible acids such as citric acid, gluconic acid or phosphoric acid) in the water (part) before the salt is added ; (2) dissolving a powdered mixture of the salt with citric acid and (fruit) sugar or sweetener optionally containing ascorbic acid and calcium, magnesium and/or potassium carbonate in the water (part); (3) addition of a concentrated aqueous solution of the salt to the water (part) with an edible acid.  Citric acid is used for the preparation of fruit-flavoured lemonade-type drinks (eg. orangeade) and phosphoric acid is used for the preparation of "Coca-Cola" (RTM). Powdered mixtures of divalent iron salts and edible acids without sugar, optionally containing ascorbic acid (and if drinking water is being used, optionally containing calcium, magnesium and/or potassium carbonates) or concentrates containing these mixtures can be added directly to the water (part) in order to make the drinks.  For the preparation of coffee or fruit tea, portions of crushed or powdered mixtures of a divalent iron salt with citric acid are mixed with the drink components which are at least partially soluble in hot or cold water and the mixture is dissolved in the drinking water part of the drink.  The preparation of orangeade or "Coca-Cola" (RTM) comprises mixing a concentrated divalent iron salt/citric acid or phosphoric acid mixture solution with the drink ingredients, or the drinks can be made using drinking or mineral water with the corresponding Fe<2+> ion concentration. "Coca-Cola" (RTM) and fruit nectar drinks contain increased Fe<2+> ion concentrations of 70-100 and 40-70 mg/l respectively without any effect on their taste.

Title: Child's seat fixer for road or air vehicles
Inventor: KLEBER HANS
IPC: B60N2/28
Filed: 1997-03-01
Abstract: The plate or frame (2) for the seat (3) is opposed by a closing tongue (3) using a receiver (6) on or behind the seat so as to hold the tongue releasably using a tongue release device (16,17). Spring-loaded locking bolts (5) near or parallel to the rear edge opposing the line of travel project sideways beyond the line of the mounting plate etc. The bolts can be pulled back into the release position by means of Bowden cables etc (17) via a handle (16) mounted below the childs seat. The tongue receiver consists of a U-section rail whose U-rail (19a) opens above to form the slot (7) for the tongue. The end crosswalls (9) of the slot are curved inwards so the length of the slot in the top part is adapted via an additional entry area to the tongue plus bolts (5). The bottom part of the slot fits the tongue only without the bolts. Mounting sleeves (10) in the narrow walls (9) run along rail and are dimensioned to suit the bolts (5). Thus, as the tongue is inserted so the bolts are pressed back against their springs until finally splaying out to press home into the attendant bushes (10) so as to bolt the tongue fast.
