Title: Waffle-iron set or the like
Inventor: HERTING HEINRICH
IPC: A21B5/02
Filed: 1988-09-08
Abstract: The invention relates to a waffle-iron set or the like with waffle irons (1) which each comprise a lower plate (2), and an upper plate (4) coupled to the lower plate (2) by means of a joint, which set is intended for baking flat waffles from waffle dough (5). In this waffle-iron set the waffle irons (1) extend from the joint (3) over a relatively large length, in particular over two or more baking places (6), i.e. it is a waffle-iron set with "genuine" waffle irons. The waffle-iron set can be designed in such a manner that the waffle irons (1) can readily extend from the joint (3) over a relatively large length, in particular over two and more baking places (6) without causing an uneven baking action in that, in addition to the pivoting movement of the upper plate (4) relative to the lower plate (2), the joint (3) permits a sliding movement, which is combined with this pivoting movement, perpendicularly to the plane of the lower plate (2), and the upper plate (4) only executes the sliding movement over the last part of the closing movement until it has reached the distance required for baking the waffle dough (5), i.e. until it is placed onto the waffle dough (5) or just above the waffle dough (5). <IMAGE>
Patent DE-3832504-A1 (DE)
IPC: E01B3/34
Filed: 1988-09-24
Abstract: In a prestressed concrete railway sleeper whose sleeper body (1) consists of two supporting bodies (2, 2') carrying the rail fastenings and a centre part (3) of smaller cross-section, the prestressing elements (4), such as, for example, steel bars, wires or strands, starting from a point where they are united in a vertical and/or horizontal plane in the sleeper centre, are run radially and rectilinearly to the sleeper ends (5, 5'), where they are anchored in uniform distribution over the cross-sectional areas of the sleeper ends. By the uniting of the prestressing elements (4) in the sleeper centre, the use of a sleeper body having a narrow, high centre web and wide sleeper ends also becomes possible for prestressed concrete sleepers, in which sleeper body only slight alternating bending moments arise in the centre part or a unidirectionally positive pattern of the bending moments can be permitted over the entire length of the sleeper. <IMAGE>

Title: Mounting rack for a withdrawable-insert power circuit breaker
Inventor: GRIMM JOERN DIPL ING
IPC: H02B11/127
Filed: 1989-03-29
Abstract: The invention is based on the object of creating a mounting rack which is integrated in a space-saving manner in a withdrawable-insert housing and on which the power circuit breaker occupies a fixed space. This object is achieved according to the invention in that the mounting rack (1) is constructed as a telescopic sliding-track system which can be withdrawn from the withdrawable-insert housing and can be pushed in together with the power circuit breaker, and in that the mounting rack (1) is integrated in the base of the withdrawable insert housing, which consists of bent sidewalls (2) and cross members (3, 4) which are arranged firmly thereon and can move. The invention is used in the case of mounting racks for withdrawable-insert power circuit breakers for accommodating a power circuit breaker which can be pushed into a withdrawable-insert housing, and can be withdrawn from it. <IMAGE>

Title: Device for regulating the discharge from an equalising tank, e.g. a stormwater retention tank
IPC: B01D21/24
Filed: 1989-04-04
Abstract: The invention relates to a device for regulating the discharge of waste water and/or rainwater from an equalising tank, e.g. a stormwater retention tank. In order to avoid blockages of the discharge opening, in addition to a predominantly float-controlled regulating device (9) for changing the through-flow cross-section (D1) of a discharge opening (4) in dependence on the height of the water level, there is provided, offset in terms of height with respect to the first, a second discharge opening (5) which is likewise equipped with a predominantly float-controlled regulating device (10). Since sediments carried along by the rainwater usually cover only the base (1) of the tank, then, even if the first, bottom discharge opening (9) should be blocked, the equalising tank is virtually completely emptied by means of the second, top discharge opening (5) once the rain has stopped. Any sediments remaining on the base (1) can be cleared away mechanically. <IMAGE>

Title: Rust preventative application - by painters roller spreading a compound on specified mat
Inventor: LUEHRS GUENTER
IPC: B05D1/28
Filed: 1989-06-30
Abstract: Those parts of harbours, sluices, weirs, docks and floating drilling platforms which are cyclically exposed to water and to air in the "splash zone", are particularly endangered by corrosion. They can be protected under water by using a painter's roller. A flexible porous texture is first laid on the surface and a viscous organic or inorganic coating is applied to it by using the roller. ADVANTAGE - This prevents the pick-up and the patchy surface finish obtained when no lining has been laid.

Title: Homogenising and aerating liq. manure in pit - by wind-driven rotary stirrers below transparent cover lowered onto pit edge
Inventor: KIBLER KURT
IPC: C05F3/06
Filed: 1989-08-28
Abstract: Liq. manure from stables, cowsheds, etc. is held in a pick (3) while being homogenised by rotating paraboloid blades (9) initially projecting from the liq. surface and then drawing in air from the space above the liq.. This space is topped by a cover (1) lowerable on to the pit side walls, and whose transparency permits access of light to aid bacterial break-down. A pump (11) above the lid constantly withdraws gas, causing progressive thickening of the liq. in prepration for mechanical spraying on to farming land. The stirrer may be rotated by wind paddles (7). ADVANTAGE - Manure is made readily usable, with min. odour.

Title: Ultrasonic dental cleaning equipment - has programmed ultrasonic followed by pressurised jet cleaning cycle of objects in rotating cage
Inventor: VIGANO ARNO
IPC: A61C19/00
Filed: 1989-10-20
Abstract: The equipment provides a controlled sequence of  ultrasonic and jet cleaning of dental and similar objects.  It has a tank (1) in which is suspended a rotatable cage (19) for holding the objects to be cleaned. Cleaning liquid can be admitted to the tank (1) from a sump (11) and can also be pumped under pressure through nozzles (15) to impinge on the object in the cage. Fixed to the bottom of the tank (1) is an ultrasonic generator (2). A programmed cleaning cycle involves rotation of the cage (19) containing the object to be cleaned in the filled tank (1) with the ultrasonic generator operated for a given time.  The tank is then emptied and clean liquid is played on the object in the rotating cage through nozzles (15). USE/ADVANTAGE - Consistant cleaning action.

Inventor: MARTL GERWALD DIPL ING
IPC: B29B13/10
Filed: 1989-12-01
Abstract: In the process described, the plastic waste, coated to a greater or lesser extent with adhesive, is (a) comminuted in the presence of a liquid which does not dissolve the adhesive, at least sufficient liquid being employed so that the adhesive effect of the adhesive layer is eliminated by the release layer formed by the liquid, and (b) the waste particles separated from the liquid are adjusted to a residual liquid content which still effects the separation of the particles from one another. The described free-flowing mixture of thermoplastic waste preferably essentially comprises chips of this waste which have a liquid content of from 0.5 to 5% by weight.
