Title: Identity-check by mouth and throat measurements - their dimensions and pressure variations of liquids swallowed being used
Inventor: WAGNER WOLFGANG DR MED
IPC: A61B5/117
Filed: 1974-03-27
Abstract: The check takes place by means of measurements in the mouth and throat space or by their indirect measurement in the controlled oral administration of medicines. The variations of the content or of the measurements or of the curvature of the mouth and throat space or of variations in the pressure of a liquid or gas passed over that space, especially during the swallowing act, is used for distinguishing between different persons, conventional instruments being used for measuring gas and liquid pressure, as well as wavemeters. The method avoids the use of additional technical devices. Technical requirements have been reduced and the use of the identity check has been simplified.

Title: Orificed concrete slab maing appts - tapered plug forced out after casting by rotating flanged screw
Inventor: FELS ERNST
IPC: B28B7/16
Filed: 1974-05-07
Abstract: The apparatus for incorporating holes in cast concrete slabs during casting, employs a plastic plug which when removed from the cast slab, leaves a round or square tapered hole. An internally threaded block is secured to the base board of the formwork, and the plug is secured by a spindle passing through it, with a threaded tip which screws into the plug. After casting, this spindle (11) which carries a flange which locates inside a recess in the interior of the plug, is rotated by a handle on its outer end, and as the screw is released from the block, the upwards pressure of the flange forces the block out. For recesses in the side of a concrete slab, the spindle through the plug is in the form of a bolt with its head in a recess in the plug, carrying an internally threaded sleeve which engages a threaded tie rod through the mould. A tapped hole through the head of the screw enables it to be engaged by screws passing through a frame round the mould, so that after casting, the screws are released, the frame removed, and a key is used to rotated the bolt head so that the plug is removed in a similar manner.

Title: Reactor fuel element with internal graphite support - for enhanced thermal and structural integrity and gaseous fission product containment
Inventor: PERLOCK JOSEPH W
IPC: G21C3/18
Filed: 1974-05-29
Abstract: Reactor fuel element of zirconium clad column stacked VO2 tablets with a bottom support of graphite of compressive strength 113.76.102 N/cm2 and tensile strength 60.95.102N/cm2 and porosity 23%. The hollow cylindrical support is machined to ensure close contact with the cladding and fuel element welded end cap to maximise heat transfer and enhance structural integrity. Gaseous fission products released during reactor operation by the fissile tablets are contained within the hollow interspace of the graphite support which also absorbs thermal expansion effects. In an alternative construction for high temperature application the interspace is insulated with Zr or AlO2 and a small inlet hole provided to compensate for loss of porosity.

IPC: B65H23/02
Filed: 1974-06-18
Abstract: The web monitoring device for fast running paper used to attach filter pieces to cigarettes, when cut up and wrapped around them, and which may be used in a control system to align the web, to indicate faults, and to indicate an overlapping joint in the web, employs a pair of capacitive electrodes incorporated in a roller over which the paper runs. Each electrode is connected to a high frequency signal generator, and the combined signals are fed to a mixer and the resulting changing signal is fed to an amplifier and equaliser to obtain a correction signal for the web drive. The two electrodes (46, 47) are housed inside the outer sleeve (51) of the roller (48) and arranged to overlap near the centre.

Title: Plastics hinge injection moulded in one operation - with gap between rotating parts later filled by sleeve insertion
Inventor: JANZ JOACHIM
IPC: E05D9/00
Filed: 1974-08-09
Abstract: A method of making a plastics hinge consists of simultaneously injection-moulding both hinge-straps in two different compartments of a common mould; one strap has the tubular gudgeons integrally formed with it, while the other strap has the hinge-pins integrally formed with it. The gudgeons are formed larger than the pins so that there is a clear gap between them; this gap is filled by a prefabricated bushing of hard matl. The hinge is a easily mifd., but there is no resultant play between the gudgeons and pins, due to the presenc eof the bushings.

Title: Resin bonded concrete rapidly produced in factory moulds - with unloading roller path parallel to hot tunnel
Inventor: KOBLISCHEK PETER
IPC: B29C67/24
Filed: 1974-09-30
Abstract: Mfr. of articles from synthetic resin concrete consists of casting into a mould, and then passing the mould through a tunnel where it is heated to harden the concrete, and afterwards removing the article from the mould. Between the mould-filling and vibrator station and the tunnel, there is a roller path mounted on a trolley which can travel transversely on rails to a second neighbouring position; at the further end of the tunnel there is a similar arrangement of rails, and roller path mounted on a trolley; along side the tunnel is a third roller path which connects up the two positions of the trolley alongside the tunnel line; thus, a mould leaving the filling and vibrating station (1) can be pushed into and through the tunnel, moved transversely across by second trolley (16) ont the parallel roller path (20), where the article is removed from the mould, the n returned to the parallel station alongside the exit from the moulding station, where it is received again by the trolley (5), and moved across for re-use. The process a rapid-turn-around of the products, which are removed from their moulds while stationed parallel to the tunnel, is possible, enabling the moulds to be quickly available for re-use. This arrangement suits the rapid setting time of resin-bonded concrete.

Title: Suspended ceiling sound insulation device - with material thickness across wall dependent on interior sound wave diffusion attenuation
Inventor: MECHEL FRIDOLIN PROF DIPL PHYS
IPC: E04B1/82
Filed: 1974-10-01
Abstract: The purpose of the fixture is to improve sound insulation in a suspended ceiling led across partition walls, at an interval from the main ceiling. The hollow space between the two ceilings above the partition walls lengthways is filled with a sound-absorbing material, such as glass fibre, mineral fibre, wood fibre, plastic or natural felt or foamed material. The thickness (D) of the material in direction at right angles to the wall plane is at least as great (in centimetres) as the difference between the required insulation and the actual sound insulation of the suspended ceiling, in decibels, divided by the characteristic interior diffusion attenuation of the sound waves inside the absorbent material.
