Title: Device for soaking pieces of dough in a salt solution and for loading a baking oven therewith
Inventor: WOERNER WALTER
IPC: A21B5/06
Filed: 1988-05-30
Abstract: The state of the art is represented by the preamble to claim 1 of Registered Utility Model 8423547 which describes a conventional salt solution tank in which the pieces of dough are immersed which have been reinforced by a separate cooling device which is indispensible in this case. The disadvantage of this Registered Utility Model is constituted by the salt solution tank which takes up a relatively large amount of space, and also by the requirement for there to be a cooling device. The object of the invention was to produce a device of the type specified in 1., which device is able to cope with a salt solution tank which saves as much vertical or horizontal standing surface as possible and makes it unnecessary to use a cooling device. This object is achieved by virtue of the characterising features of claims 1 and 11 respectively in the case of a device in accordance with the preamble to claim 1. The advantage of this solution is constituted by the possibility of using a salt solution shaft or tank which saves vertical standing surface, is extended in a vertical direction and into which the unit made up of a frame (14, 16) with immersion grids (18) on the one hand and the covering grid (40) on the other can be immersed; and/or the possibility of processing uncooled pieces of dough without the use of baking sheets. <IMAGE>

Title: Method for regulating the operation of pumps
Inventor: BOHN HEINZ DIPL PHYS
IPC: F04D15/00
Filed: 1988-07-15
Abstract: The invention relates to a method for regulating the operation of pumps on one line of locations from a family of lines of locations which are composed of operating points relating to the delivery head above the delivered stream and is intended to make it possible to completely dispense with the special sensors which require a larger or smaller outlay, are prone to disturbance and expensive and are used during regulation in line with a constant or a guided delivery head on or in the pump or in the delivered medium to determine values which can be utilised for the purposes of regulation. It is proposed according to the invention that measurements be taken not by special sensors, either in the delivered medium or in or on the pump or on the motor, but that measurements be solely taken from the supply of electric power, i.e. from the mains supply to the motor, in order to determine a parameter from them which matches the line of locations from the delivery head above the delivered flow and adjusts an actuator such as a phase control system, a frequency convertor or the like for adjusting the rotating speed of the pump and/or the pump motor in such a way that the actual line of locations determined in this manner matches the desired line of locations.

Inventor: BRUNSCH KURT
IPC: D05B85/02
Filed: 1988-08-19
Abstract: The threading of a sewing needle or a sewing-machine needle, because of the narrowness of the eye, necessitates not only good power of vision, but also a dexterity which overtaxes most people. The result is: a time-consuming job which causes much annoyance and which puts many people off sewing work. By opening the eye from outside by means of a resilient lever which is obtained by weakening the eye frame, the end of the lever, together with the thread loop, can be drawn into the eye by a pull, the thread sliding through the opening orifice into the eye, whilst the lever once again jumps against its abutment which limits its outward movement.

Title: Device for biological cleaning of waste water - has inlet water flow divided unequally between cascade denitrification and nitrification to equalise biomass formation
Inventor: REIMANN HANS DR RER NAT
IPC: C02F3/10
Filed: 1989-10-20
Abstract: Waste water is cleaned in an activation process in which the water passes through a multi-stage nitrification and denitrification cascade system. The stages of the cascade are supplied with reducing quantities of water in the direction of fluid flow, and the sludge is recirculated from the last to the first stage of the cascade.  A two-stage cascade may be used, in which the first stage receives about 60% of the waste water quantity, and the second stage about 40%. In a three-stage cascade, the division of the water quantity would be 42%, 33% and 25%, while in a four stage cascade the corresp. quantities would be 34%, 27%, 20% and 19%.  An anaerobic zone for treatment of phosphates is provided upstream of the cascade, and at least one stage of the cascade is provided with a support material for the growth of a biomass. A freely floating lightweight material may be used for this purpose, and this support material is retained in the different stages of the cascade. USE/ADVANTAGE - Existing waste water cleaning systems of this type use a cascade whose stages consist of nitrification and denitrification processes, and each stages receives and  equal fraction of the total water flow quantity. This leads to an excess of activated sludge biomass forming in the early stages of the cascade, and a corresponding shortage in the later stages.  The equipment used must therefore be undesirably large if effective treatment is to be ensured. This invention overcomes these disadvantages by dividing the water flow quantity unequally between the stages of the cascade.
