Title: Thermoplastics sliding clasp fastener - has band halves each formed in one piece by injection moulding (NL 27.9.77)
IPC: A44B19/34
Filed: 1977-03-22
Abstract: Both halves of the sliding clasp fastener each consist of a connector band (1, 2) made of a thermoplastic material. The band is injection moulded similar in form to an extremely finely woven material whose cross threads (1a, 2a) are as double threads. The ends (1c, 2c) of these double threads are made in one piece with the heads. The connector heads (3-4) which form the clamp row of one half of the zip are joined by a thread (5, 6) round which the heads are formed. In this way, the production of fasteners is considerably simplified in that all parts of the fastener are produced in one moulding process. This method also avoids incorrect colour matching of the band with the fastener heads. The bands can easily be fixed to unwoven materials by use of high frequency, or ultrasonic welding methods.
Patent DE-2713404-A1 (DE)
Title: Oil dip-stick for automatic gearboxes - has flexible steel rod with coils either side of marker notches to increase flexibility and prevent smearing
Inventor: MARTIN HARRY DIPL ING
IPC: G01F23/04
Filed: 1977-03-26
Abstract: The oil dip-stick is used in vehicles esp. for automatic gearboxes. It comprises an oil-filler tube (3) which has several bends, into which the oil level measuring rod is inserted. The dip-stick itself consists of a rod of flexible spring steel of circular cross-section (6). The rod carries notches (7) (8) to indicate the maximum oil level marks. Near the marker notches the metal rod is wound with one or more helical turns (10). The diameter of the turns is close to that of the guide tube/filler tube into which the dip stick is inserted. The purpose of the coiled parts of the rod is to prevent the section between them, which carries the oil smear indicating the level, coming into contact with the side walls of the tube, especially at the bends, and disturbing the oil deposit.

Title: Fully mechanised prodn. of blow moulded thermoplastic containers - by injection moulding into equipment which performs every operation
Inventor: HAVELIN ROBERT
IPC: B29C49/42
Filed: 1977-05-03
Abstract: Thermoplastic containers are produced by injection moulding the rough shape in a multi-tool mould and blow moulding. A blowing needle is inserted into the lower and open end of the moulding which is then surrounded by the mould with its open end enclosed; the needle thus provides an internal form for a tubular opening and/or filling hole. When the mould is closed parts of the moulding project, pref. from the top of the mould; when the mould is opened grips engage the projecting parts of the blown container and convey it to a next device, e.g. for dressing off flash. Prods. are obtd. in a single continuous mechanical process without any manual operation, and thus the risk of contaminating the moulding is eliminated.

IPC: E04G21/02
Filed: 1978-03-15
Abstract: The culvert structure is constructed by open-cut working. Before the inner surface of the plate pipe is lined with a concrete layer of several cm, it is necessary to wait at least twice as long as required for half of the change in the inside diameter of the pipe to occur, which change can be expected overall under the load of the fill material. The concrete layer is preferably applied by spraying and a structural steel lattice can be installed here.

Title: X=ray contrast medium injection tool - for vaso-seminal ducts with inflatable balloon seals for pars prostatica
Inventor: HARTUNG FRITZ DR
IPC: A61F2/958
Filed: 1978-04-15
Abstract: A device for the introduction of X-ray contrast media in the spermatic ducts and vesicles of male patients for the prepn. of vasoseminal vesiculography consists of an elastic hose which can be inserted through the urethra into the bladder. A miniature balloom at the distal end can be inflated by fluid pressure to close the pars prostatica upstream, and a second miniature balloon at the downstream end closes the downstream side of this part. Openings between the two balloon seals can then be used to inject an x-ray contrast fluid into the spermatic ducts and vesticles. This is a method which is less likely to injure the patient than the conventional introduction of a special catheter through the urethra in the ductus ejeculatorius or the exposure of the vas deferens after a scrotal incision and puncture with a cannula.

Title: Vapour deposition appts. evaporator boat and lid - with matching sloping faces and spring clip action connection together with lugs for direct resistance heating
Inventor: KIENEL GERHARD DR
IPC: C23C14/24
Filed: 1978-05-20
Abstract: The rectangular boat has two narrow sides, and the top of each of these sides is bent outwards and downwards to form two sloping zones, each leading to a horizontal connecting lug. The lid consists of an inverted "U" with two legs extending downwards on the long sides of the boat, whereas the flat top of the inverted "U" is perforaged. The two narrow ends of the top of the lid each end in a sloping zone fitting on top of the two sloping zones where the lugs join the boat. Each leg of the lid ends in a V-bend so the lid fits on the boat in the manner of a spring clip. Two sloping zones are pref. at 15-45 degrees w.r.t. the horizontal. The lid is securely fixed on top of the boat, and is also connected to the lugs used for direct electric resistance heating of the boat. This means that the lid is uniformly heated so that no vapour from the material being evaporated condenses on the lid.

Title: Underfloor heated raised floor panels - have underside adhesive fixing for substructure knobs partially surrounding heating pipes
Inventor: FEIST ARTUS
IPC: E04F15/02
Filed: 1978-05-27
Abstract: Assembly panels with upright protruding knobs are set on the load-bearing floor structure; on top of the knobs there are floor panels for walking on, while heating pipes run between knobs, of smaller dia. than knob height, leaving a slight gap below the top panels. The underside of the latter is coated with adhesive for fixing on knobs. This adhesive (20) partially encloses the heating pipes (16), and may form wedges on both sides of the pipes, between them and the top panels (18). The adhesive may contain heat-conducting fillers, and have high specific weight and non-thirotropic qualities. This provides effective heat transfer between pipes and panels over a wide area, while avoiding mechanical loading on pipes which might reduce their cross-section.
