Title: Control system for furnace - has combustion chamber and flue duct with flap in air supply duct, for opening on demand for combustion chamber operation (NL 1.3.82)
Inventor: KUTZNER LUITPOLD DIPL ING
IPC: F23N1/04
Filed: 1980-08-08
Abstract: The system has an air supply duct and a discharge air passage from the furnace housing room. In the supply duct is mounted an air control flap (26), opening when the combustion chamber (10) is exposed to heat demand, thus enabling starting operation of the combustion chamber. In the flue duct (14,16) there is mounted a conventional flue duct flap (18). The combustion chamber operation may be dependent on the opening of both air supply and flue gas flaps. On opening, the air supply flap transmits a signal tripping the opening of the flue gas flap, while the latter, on opening, transmits a signal enabling the combustion chamber operation start. When the combustion chamber is supplied with air from the surrounding room, the air supply flap may be fitted into a supply duct to the room.

Title: Slurry outlet on centrifuge bowl - having internal closure on screw inside bowl to give controlled opening
Inventor: HILLER GEORG
IPC: B04B1/20
Filed: 1980-09-27
Abstract: The solids phase is removed at least partially from a centrifuge by allowing it to leave as a thickened slurry from outlets arranged at some point above the bowl wall level. This outlet has a mechanism whereby it is opened and closed. The outlets are mounted at positions around the bowl. Inside the bowl there is a rotating screw or inner core which has a different speed from the bowl. Mounted on this are flights which serve to shut off the outlets in various positions. The amount of time the outlets are open depends on the differential speed between the bowl and the screw.. The centrifuge is to separate solids from liquids in slurries. The mechanism is very uncomplicated for opening the sludge outlets and needs no mechanical parts which need to be produced with great accuracy.

Patent DE-3118284-A1 (DE)
Title: Arrangement for the protection of bridges against overcurrent and short-circuit currents, using controllable semiconductors
Inventor: KRANERT KLAUS DR ING
IPC: H02H7/127
Filed: 1981-05-08
Abstract: The invention relates to an electrical system (installation) in which an electrical power generator supplies a three-phase mains power supply (network) via a rectifier bridge and a converter bridge. In the event of a short-circuit in the mains power supply, the invertor trips and its fuses burn out. The consequence is a short-circuit in the DC intermediate circuit. A resistor which is connected in parallel with a fast-action switch limits the current to the rated current. The invention attempts to avoid the additional cost in terms of valves and their electronics caused by this protection measure by connecting a series circuit (consisting of a resistor and a controllable semiconductor) in parallel with at least two controllable semiconductors of the converter bridge. Current transformers per phase determine if the limiting current value has been exceeded and cause an extinguishing device and the limiting resistor to be switched on. <IMAGE>

Patent DE-3121770-A1 (DE)
Title: Saddle, in particular for pedal cycles
Inventor: TITAU REINHOLD
IPC: B62J1/00
Filed: 1981-05-26
Abstract: The object of creating a saddle which has substantially better properties, particularly in respect of riding comfort, than previously customary saddles is achieved according to the invention by virtue of the fact that two springs wound in the shape of a truncated cone and composed of steel wire are arranged on a load-bearing frame in such a manner that the larger diameter points upwards. The diameter of the upper spring winding is dimensioned to be as large as the selected saddle shape permits. The springs are filled with correspondingly shaped parts made of foam which for their part are a component of the saddle body made from foam or are positively connected thereto. The compressive hardness of each of the parts is matched to that of all the others in such a manner that the load is predominantly absorbed by the foam. The use of hard support parts between the springs and the body of the rider is thus superfluous and complete adaptation of the saddle, in the region of the sitting area, to the anatomical shape of the rider is possible whilst retaining comfortable, damped springing and good transverse stability. The weight is virtually uniformly absorbed by a relatively large surface so that painful pressure points which otherwise easily occur in the region of the ischia are avoided. <IMAGE>

Title: Control valve arrangement with at least two directional control valves in double-flow construction
Inventor: HOEFER FRIEDRICH-WILHELM
IPC: F15B13/06
Filed: 1981-08-06
Abstract: A control valve arrangement (10) for stacker trucks is proposed which serves to control two consumers in parallel at different pressure levels. It comprises at least two directional control valves (14, 15) in double-flow construction, from which, downstream of the latter valve, a circulation passage (26) allocated to the first flow and a distribution passage (25) allocated to the second flow are brought together via a first transverse connection (51). From there (51), a second transverse connection (56) leads via an additional directional control valve (12) in single-flow construction to the second circulation passage (27) upstream of the directional control valves in double-flow construction and further via these directional control valves to the tank (34). In this way, simple, standard directional control valves (12) in single-flow construction can be combined with directional control valves (14, 15) in double-flow construction and can control flows of different magnitude. In addition, different pressure protection measures can be carried out for both flows. <IMAGE>

Title: Vending system for weight-related products, comprising balances and cash registers
Inventor: BOELLING CHRISTOPH
IPC: G07G1/14
Filed: 1981-11-12
Abstract: A vending system for weight-related products uses a plurality of keyboard-operable calculating and printing balances which inscribe on an interim receipt the weight-related product data of a purchasing transaction, such as the individual amounts of the products thus acquired, the final amount of the purchasing transaction and, if appropriate, the weights and unit prices of the individual products. The vending system also includes a set of cash registers which are themselves equipped with a printer for a final receipt which concludes all the purchasing transactions of a particular customer and in which at least the final amounts of the various purchasing transactions and their total amount are recorded in terms of the products data. In order to provide an inexpensive vending system which is operationally reliable and which is simple to handle, both the balances and the printers are connected in terms of data transfer to a central memory which is divided into data blocks with a predetermined block address. The product data of a purchasing transaction which are obtained on the balances are stored in these data blocks according to a predetermined sequence and the associated block address is inscribed on the interim receipt in a machine-readable code script. This can be detected by a reading device of the particular cash register used and calls up the associated product data of the respective data block into the computer of the cash register, where they are taken into account in the preparation of the final receipt.
