Title: Automatic brake for trailer - uses inertial operating masses to drive brake linkage independent of drawbar fittings
Inventor: SCHMIDT HANSJOERG
IPC: B60T13/08
Filed: 1980-02-01
Abstract: The automatic trailer brake has one or more inertial masses (1) which are displaced in the direction of travel when the towing vehicle brakes. These masses apply the trailer brakes via a mechanical or hydraulic linkage. The brake operates without a complex telescopic drawbar. The brake can be applied to any vehicle and the masses are chosen to suit the trailer weight. For improved mechanical advantage the masses operate levers linked to the brake controls. No brake connection is required between the towing unit and the trailer.

Title: Bleached sulphite wood pulp mfr. - where waste water from magnesium hypochlorite bleach is roasted with waste sulphite lye
Inventor: DRASEN EDMUND DIPL ING
IPC: D21C9/14
Filed: 1980-02-11
Abstract: The pulp is obtd. by digestion of lignocellulose material with magnesium bisulphite; and the waste sulphite lye is roasted to reclaim MgO and SO2. The pulp or cellulose obtd. is subjected to at least one bleaching treatment using Mg(C10)2 plus Mg(OH)2; and the waste bleach water is roasted with the waste sulphite lye. At the end of the bleaching treatment, the cellulose is pref. treated with the condensate obtd. by the evapn. of the waste lye. The condensate acts as a source of H2SO3 and H2SO4 or their acid salts, and is used in a quantity corresp. with the amt. of residual hypochlorite and undissolved Mg cpds. in the pulp. The invention eliminates the need for the separate treatment of waste bleach water.

Title: Apparatus for removing oxygen from the head space of filled folding containers
IPC: B65B31/04
Filed: 1981-03-09
Abstract: An apparatus for removing oxygen from the head space of already filled folding containers, by means of which a neutral gas, for example nitrogen, is blown into the head space, in order to protect the packaged filling material from the influence of oxygen. In order to achieve as continuous a flushing effect as possible and to prevent atmospheric oxygen from penetrating into the head space on the way into the folding and closing station during the folding and closing, it is proposed, according to the invention, to arrange a gas nozzle directly at least on one of the movable folding and/or closing tools, in such a way that, during the folding and closing movement, the head space of the folding container can be loaded with the gas. In addition, by means of further blowing-out orifices of the gas nozzle, care can be taken to ensure that even the more immediate vicinity at the head end of the folding container is greatly enriched with neutral gas. <IMAGE>

Title: Sliding bearing of concrete slabs expanded in one or two directions
Inventor: SCHNABEL WINFRIED DIPL ING
IPC: E01C7/14
Filed: 1981-03-19
Abstract: The invention relates to a method for the sliding bearing of concrete slabs which are superimposed or supported on compacted ground and expanded in one or two directions and which are separated from one another with or without intermediate layers. Said object is achieved in that sliding bearings in point or line form are constructed between which two or more foils filled with air are laid. In this arrangement the foils are designed in such a manner that individual air cushions are formed. Since the currently known foils are not absolutely gastight, air escapes over time from the cushions so that the concrete slabs in their final state are supported only on the sliding bearings in point or line form.

Title: Apparatus for driving dowels into dowel holes in workpieces
Inventor: HOFFMANN HERBERT
IPC: B27G11/00
Filed: 1981-04-09
Abstract: The apparatus has a plunger, movable along a guide and intended for ejecting in each case a dowel through an ejection opening, which dowel is fed individually in front of the plunger by a dowel-feeding device, and furthermore a device for feeding glue to the dowel holes in each case before a dowel is driven in, which device is provided with a valve actuated before the triggering of the plunger and thereby releasing a predetermined quantity of glue. The device for feeding glue to the dowel holes comprises a glue nozzle which can be moved between an operating position projecting into the area of the outlet opening of the dowel guide and a position removed from the area of the dowel guide. Before and during the feeding of glue, this glue nozzle is held in its operating position projecting into the area of the outlet opening of the dowel guide, but before the respective triggering of the plunger it is moved into the position remote from the dowel guide.
