Title: Composite metal objects made by diffusion welding - where parts are immersed in molten salt subjected to high pressure by steam or air
Inventor: UNTIIOV VIKTOR JURIEVITSCH
IPC: B23K20/14
Filed: 1977-07-20
Abstract: The metal parts forming the composite are assembled together and immersed in a high temp. melt subjected to pressure so that the parts are forced together and welded.

Title: Electromechanical filter with parallel mechanical resonator bars - has coupling wire between non-adjacent resonators in addition to one between torsional and non-adjacent flexural resonator
Inventor: ALBSMEIER HANS
IPC: H03H9/50
Filed: 1977-08-23
Abstract: The filter has mechanical bar resonators with parallel axes lying in a plane, and coupled with each other by at least one coupling wire. Electro-strictive transducer resonators are provided at the input and output. An additional coupling element is provided, generating at least one attenuation peak. The filter comprises mainly flexural resonators and has at least one torsional resonator, to which at least one of the additional coupling element is connected. When an additional coupling element is connected to a torsional(4) and to a flexural resonator, not directly adjacent to it (eg 1, 7), at least one further additional coupling element(15, 15'; 16, 16') is provided. This steepens the attenuation characteristic on the high frequency side, and makes it less steep on the lower frequency side.

Title: Labelling machine with continuous strip feed forming curtain - transports product along conveyor belt sections separated by transverse gap with label pressed against product
Inventor: WANGERMANN JOCHEN DIPL ING DR
IPC: B65B63/02
Filed: 1979-05-08
Abstract: The labeling machine has a continuous strip of labeling material forming a form of curtain. The product is driven up against the curtain, which is conveyed through a gap in the support for the product. The movement of the product causes the label to be wrapped around it.

Patent DE-2932839-A1 (DE)
Title: Doctor blade support beam - has heaters to induce bending to compensate for doctor blade deflection
Inventor: KLEIN HEINZ
IPC: B05C11/04
Filed: 1979-08-14
Abstract: The device gives more uniform film thickness when spreading plastic material on rollers by means of a doctor blade. The blade normally deflects under the load exerted by the material which is being spread on the roller. The doctor blade support beam is fitted with heaters which can be separately controlled. The heaters are fitted above and below the beam in a staggered manner. Temperature differences are induced to bend the beam and thus compensate for the deflection of the doctor blade. The overall deflection is cancelled out and the blade remains straight under load. A uniform film thickness is therefore produced on the roller.

Title: Sewing machine position adjustment drive - has microprocessor set of at least eight bits
Inventor: SCHUELER PETER
IPC: H02P23/18
Filed: 1979-09-20
Abstract: The position adjustment drive is particularly for a sewing machine, having a micro-processor set of at least 8 bits. from which different operating sequences can be separately derived. To control the speed of rotation there can be a phase-locking unit functioning as a three-point regulator, the unit having an oscillator with voltage control followed by a comparison stage acting as a phase comparator, from whose output a back-coupling loop leads to the voltage-control input of the oscillator. A filter can be mounted in the loop, to reduce the back- coupling effect at high frequencies.
