Patent DE-2438715-A1 (DE)
Title: Cellular concrete prodn. - from coarse sand, cement, water and glycolic acid or its salt as foaming agent
Inventor: VENOHR GUENTER
IPC: C04B28/02
Filed: 1974-08-12
Abstract: Cellular concrete is prod. from coarse sand, cement, water and a foaming agent is improved by using as the latter a salt of glycolic acid, esp. sodium glycolate in an amt. of at least 0.3 wt.% pref. 0.5 wt.% w.r.t. the cement, depending on the grade of the concrete (0.5% for concrete class B). The dry components are thoroughly mixed together, and then water is admixed. Potasium or calcium glycolate, and salts of citric and tartaric acids can also be used. Prodn. of prefabricated building elements or casting of concrete constructions in situ is facilitated because the expansion takes place already in the mixer. The consumption of the foaming agent can be accurately calculated on the last of the cement content and the required quality grade of the cellular concrete. There is no premature setting. The distribution of the pores is very uniform; the bulk density is 16-20% lower than that of known compsns; the concrete has adequate strength after 24 hrs.

Title: Crane or trolley-guiding solid welded girder component - with open-sectioned lengthways bend supports forming u-profiles, and cross-plates
Inventor: DEGENHARDT HEINRICH DIPL ING
IPC: E01D2/04
Filed: 1975-02-27
Abstract: The component is part of a welded girder, made on the solid-wall principle, incorporating a stem piece with a running track for a crane or trolley etc., and also a chord piece and transverse partition pieces to the track has a T-shaped-section welded to the stem and chord pieces. Inside the girder (1) there are bend supports (10), running lengthways, with an open cross-section set at an interval from the stem or chord (2) so as to combine with this to form a shallow-U-shaped lengthways profile. The bend supports are also connected to stem and chord by one more crossplates (12), lying between two transverse partitions, in each case. The bend supports may be in the form of a continuous support, with the transverse partitions divided for it to pass through. Dangers of crack formation in the weld seams connecting the stem to the other parts is prevented, and welding points are readily accessible.

Title: Magnetic suspension for tracked vehicle - has three layers of permanent magnets using attraction and repulsion for weight saving
Inventor: EISELE HERBERT
IPC: F16C39/06
Filed: 1975-04-08
Abstract: The tracked vehicle is supported on magnetic fields using the interaction of a fixed track and permanent magnets on the vehicle. For an improved support, using the minimum number of magnets, the track (11) is spaced in a horizontal slot in the side of the vehicle with the vehicle magnets positioned over and under the slot. The track is fitted with permanent magnets (5) which are attracted to the magnets under the slot (4) to lift the vehicle, while they are repelled by the magnets (3) above the slot which lift the vehicle by repulsion. This effectively doubles the support effect for the vehicle.

Title: Thin cupboard door hinge - has flat body mounted hinge part with channel system at back for distribution of injected adhesive
Inventor: THOMAS EBERHARD
IPC: E05D5/02
Filed: 1975-04-15
Abstract: Hinge arrangement for thin-walled doors, e.g. bathroom cupboards. The leaf-mounted hinge part (18) has two pivots which connect via rods (14, 16) to corresponding pivots on the body-mounted hinge part (12). The latter fits into a shallow recess on the cupboard body (24) and has on the rear face a system of distributing channels (36) which connect to an adhesive injection hole (34), to fix this part by gluing-on. The procedure is to place the flat hinge part without adhesive into the tight fitting recess and then to inject under pressure the adhesive through hole (34), which then spreads evenly along the channel system and creates adhesive contact between hinge part and cupboard body. The channel system has no outlets beyond the edges of the hinge part, so a pressure increases on the injection hole indicates that the entire system is filled up with adhesive.

Title: Thermoplastic film strip feed - has adjustment to control quantity delivered to the textile machine
Inventor: BRAENDLE KLAUS
IPC: D04B27/10
Filed: 1975-11-15
Abstract: An apparatus is claimed for the delivery of strips of thermoplastic film to a textile machine, such as a loom or a knitter, where the strips have been formed by division of the film and then heat stretching the strips. After the division of the thermoplastic film and thermal stretching of the film strips, they are fed direct to the textile machine using this feed material.

Title: Film or tape cassette spool flanges - have cutouts which allow spools to be placed closer together
Inventor: PROCHNOW CLAUS ING GRAD
IPC: G11B23/087
Filed: 1976-03-11
Abstract: At least one of the coplanar spools has flanges with cut-ints into which the flanges of the other spool can penetrate; one of the cut-out flanges can rotate relative to the spool core. In the version illustrated, the cut-outs turn the flanges into (possibly cycloidal) gears with deep teeth. The spools each have one freely-rotating flange, and are oppositely placed, so that the freely-rotating flange of each meshes with the fixed flange of the other. Each spool has a ring groove on one side, which fits over a ridge on the cassette upside down. In a second version, one spool is normal, with fully circular flanges. The other has cut-outs to accept part of these flanges. The cut-out part is kept in the correct positon by stops on the cassette body.

Title: Transporting moulded gypsum panels through dryer - using conveyor with suction and air cushions to avoid damaging profiles
Inventor: BREKELL HELGE
IPC: B65G51/03
Filed: 1976-04-14
Abstract: Four zones are used in the furnace (A) charging zone, using suction boxes to lift the panels so they are in contact with driven transport roller; the space below this zone is open so damaged panels are easily removed. (B) Distribution zone, in which the panels are moved sideways on an air cushion to form e.g. three rows. Pneumatic cylinders then push the suspended panels into (C) the drying zone, where both upper and lower jets of air are used to suspend the panels while they are transported by brush rollers engaging with the upper surface of the floating panels. The dry panels then enter a discharge zone (D). Used for the drying of moulded gypsum panels reinforced with glass fibre, where one surface of the panel has a pattern or profile which must not be damaged during drying.
