Title: Internal sound sensitivity treatment system - with sound energy frequency modulated as inverse function of control modulation
Inventor: BELLER ISI DR MED
IPC: H04R25/00
Filed: 1978-08-08
Abstract: The system treats troubles connected to internal sound sensitivity in speech therapy, by delivering modulated sound energy into the ear. The energy is frequency modulated as an inverse function of a control modulation. This is done starting from a frequency near but below the highest audible one corresponding to a zero value of the control modulation factor. The power of the sound energy delivered into the ear can be constant, and near to but below the pain threshold. The equipment used can have an oscillation generator whose frequency is controlled electrically as an inverse function of a modulation factor, as supplied by a tape recorder output.

Patent DE-2908035-A1 (DE)
Inventor: PERTZEL KURT
IPC: B23K1/002
Filed: 1979-03-01
Abstract: In the production of a cooking utensil, in which at least two parts of different metals, such as aluminium alloys or steel, are joined together by induction brazing, aluminium base material is rolled together with the brazing material to a preliminary rolled thickness in a first step at rolling heat. In a subsequent cold-rolling operation, the final thickness is achieved. This is preferably 1 to 5% of the initial thickness of the base material. This method gives a uniform join, extending over the entire joint face, between the two parts to be joined.

Title: Concrete stress members compound layered sheathing - has heated inner plastics layer swelling into cavities in outer insulating layer
IPC: E04C5/08
Filed: 1979-03-22
Abstract: Concrete load bearing structures are prestressed, when concrete is hard, by stress members (1) sheathed in two or more layers of plastics. The inner layer is deformable and joins firmly onto the outer layer under heat hardening. The outer layer is of heat insulating material (3) with linked hollow spaces, sealed on the concrete (5e side by a membrane, but open on the plastics layer side.

Title: Quantitative fluid measurement - involves synchronised filling and weighing, and emptying of containers without interrupting flow
Inventor: CISIKOV VLADIMIR M
IPC: G01G13/14
Filed: 1979-10-18
Abstract: The appts. is used for the quantitative measurement of material with flow characteristics which involve measuring the wt. of the material as it flows continuously.
