Title: Stapedial muscle reflex contraction examination - using acoustic impedance measurement under test sound before and after stimulus application (DK 22.8.77)
IPC: A61B5/103
Filed: 1976-01-05
Abstract: The system is for the examination of the reflex contraction of the stapedial muscle when the ear is stimulated, by measuring the variation in acoustic impedance of the middle ear. The acoustic impedance of the ear examined is measured by means of a test sound. The ear is stimulated and a further impedance measurement made during the rest period after the stimulus has ceased. The two measurements are compared and a signal is produced if they differ. The measurement made can be that of the acoustic elasticity and the auditory passage can be sealed hermetically before the measurements are made. The air pressure for the elasticity measurements can be set to a value corresponding to maximum elasticity.

Title: Temp. display for molten metal in mould - uses repetitively sampled values from network of sensors to provide continuous graphical display
Inventor: HOOVER BRADLEY RAY
IPC: G06G7/30
Filed: 1976-08-25
Abstract: The system has a control circuit which repetitively produces first, second and third control signals. A shift circuit receives the first control signal from the control circuit. This shift circuit has several outputs and at least an input connected to a source of distinct data values. The shift circuit is designed to repetitively sample, in a shift progression a predetermined number of distinct data values consecutively produced. Each of the repetitive samples define a sample period in which the data values each appear at one of the different outputs. A computing circuit receives the second control signal. This computing circuit has several inputs connected so as to simultaneously receive in parallel the different outputs from the shift circuit. The computing circuit produces the output signals of the shift circuit during sampling periods, an interpolated segment connecting continuously an adjacent pair of distinct values. The interpolated segments produced during adjacent sampling periods contain a common and distinct data value. A display circuit receives the output signal of the computing circuit and the third control signal. This display circuit produces from these signals a continuous display.

The system has a switching stage (PR) which produces second signals (B) which are sent in the place of the first signals provided by the data memory (DS). The switching stage (PR) has a control unit (ST) which creates control signals (A) as a function of the position of an image test switch (TS). It also has a coder (CD) which receives the control signals (A) and which produces the second signals (B) as a function of the control signals (A).

Title: Processing tobacco leaf stalks for use in cigarettes - by cutting up material with fibres separated from core and humidified before softening
Inventor: PITIE BERNARD
IPC: A24B3/14
Filed: 1976-12-13
Abstract: The process enables the stalks of tobacco leaves to be used in cigarettes, in conjunction with the normal tobacco filling. The stalks are first cut up into smaller lengths and the fibrous parts are separated from the core. The fibrous parts are then crushed to flatten them and the resulting material is shredded in order to loosen the individual fibres. These separated fibres tend to slide over each other and are fixed in an irreversible manner by submersion in hot water, followed by treatment in a vacuum chamber to equalise the humidifying effect. The product is then finally shredded.

Title: Reactor for mfr. of moulding from a reactive compsn. - has tank for each reactant, mixing chamber, feed lines and return line with selective cutoff
IPC: B29B7/76
Filed: 1977-02-25
Abstract: Device has containers for each component; a mixing chamber; and a separate feedline system for each component with a connecting line from container to mixing chamber, via a conveying pump. There is also a return line leading back to the container which can be switched off during the mixing phase and so allows the components to circulate. A conveying pump is used in such a way that its through put vol. per unit of time is adjustable. It is controlled so that the throughput of the conveying pump is reduced w.r.t. the mixing phase when the return line (non-mixing phase) is switched on. The devide minimises risk of accumulation of reactive material during the non-mixing phase with consequent undesirable fouling of equipment caused, e.g. by increase of viscosity through cooling.

Title: Tunnel driving and lining system - assembles rings inside shield and expands on moving forward sequentially
IPC: E21D9/06
Filed: 1977-04-20
Abstract: The tunnel driving system uses a mobile shield with stays and prefabricated rings forming arch sections, as the shield moves forward as revetment. In a first phase one or more almost complete rings of prefabricated arch sections are assembled inside the shield, keyed together and with seals round the periphery. In a second phase the shield is advanced for a distance equal to a ring width, so as to free the last ring upstream of the shield. In a third one, the last ring is expanded and provisionally keyed and sealed to the one directly upstream of it, and in the fourth it is finally keyed up.
