Inventor: GUIDAT BERNARD
IPC: H01F41/02
Filed: 1982-01-27
Granted: 1985-05-15
Abstract: 1. Process for producing a piece having at least one dielectric separating layer from a ferromagnetic blank (30), a recess (31) being worked into the blank, which recess is so formed that the individual parts of the blank are joined together by at least one border-bridge (32), whereupon a non-ferromagnetic material (34) is introduced into the recess and the blank is subjected to a material-removing operation so that the ferromagnetic parts are joined together only through non-ferromagnetic material, characterised in that the blank (30) is heated in the form of a block to a temperature at which it is plastically deformable and plastic deformation of the blank is carried to form the said recess (31), and that after introduction of the non-ferromagnetic material (34) into the recess, the blank together with the non-ferromagnetic material introduced is compressed before the material-removing operation is carried out.

Title: Shower hose
Inventor: BUZZI GUNTHER
IPC: F16L33/22
Filed: 1982-03-11
Granted: 1985-09-05
Abstract: The pressure hose is preferably a shower hose having an inner hose and an outer hose, between which can be provided preferably axially directed reinforcing threads and/or a reinforcing helix. At the free end of the pressure hose is provided a connecting nipple comprising two cross-sectionally in each case substantially circular jackets between which is clamped the hose end. In the clamping area, the inner hose and optionally the reinforcing thread surrounding it are longer than the outer hose and the reinforcing coil and are wrapped round towards the outside to form a hose wall reinforcement, which, after compressing the two jackets, ensures a reliable hold of the connecting nipple.

Title: Apparatus for copying a reference winding for making a production winding of similar dimensions
Inventor: HAUSLER WERNER
IPC: B65H61/00
Filed: 1982-07-16
Granted: 1987-11-12
Abstract: The method and apparatus may be used for copying a reference winding in order to produce a production winding similar to a reference winding. With regard to making spools of sewing thread, the production winding may have the same length of thread and winding cross-section as the reference winding. Alternatively, the main aim may be to make production windings having the same cross-section as the reference winding. According to the invention, reference data is stored in a microprocessor system whilst making the reference winding. Production data is the derived whilst making the production winding. Corresponding instantaneous values of the reference data and the production data are compared in order to derive an error signal. The error signal is supplied to an adjustable tensioner, whereby the tension of the material is adjusted, whilst making the production winding, so that a production winding is made which is similar to the reference winding. One arrangement uses a measuring wheel and a revolution counter to provide the data. Another arrangement uses a revolution counter and an arm which pivots in response to an increase in the cross-section of the winding to provide the data.

Filed: 1983-12-20
Granted: 1987-08-27
Abstract: Structured light patterns are introduced into the arc vicinity within the field of view of the integral optical sensor on a gas tungsten arc welding torch. Processing the image yields data needed to guide the torch and control and assess the weld process. The optical welding torch has a projector system with a remote light source and flexible fiber optic bundle over which the light pattern passes to an exit projection and relay assembly mounted on the torch. A programmable laser pattern projector, useful for other applications, has a beam deflection device that traces a two-dimensional pattern on the entrance of a coherent fiber optic bundle; no moving parts or electrical connections are needed at the terminal end. An optional modulator changes the pattern intensity spatially or temporally.

Title: Measuring device for testing the density of an ear impression and/or an otoplastic
Inventor: BRUCKHOFF HENNING
IPC: H04R25/04
Filed: 1983-08-22
Granted: 1987-12-17
Abstract: A measuring device for checking the tightness of an ear impression mold serving as pattern for the production of an otoplastic and/or of an otoplastic inserted in the auditory passage of an ear through which an air pressure deviating from the air pressure prevailing on the outside can be produced, via an air permeable connection, in the inner space defined by the ear drum and the ear impression or otoplastic. Through the device changes in the generated deviating air pressure can be measured. The air permeable connection is connected to a pump serving for the generation of the deviating air pressure via a pressure chamber whose volume is a multiple of the volume of the inner ear space. A control circuit presetting the timing of the pumping and measuring process is provided. The device is insensitive to differences in the volume of the inner ear space and produces reproducible test results which reliably indicate the quality of the ear impression of otoplastic.

Title: Ball joint
Inventor: ITO EIICHI
IPC: F16C11/08
Filed: 1984-11-07
Granted: 1987-01-22
Abstract: The subject of the invention is a ball joint for motor vehicles with a bearing shell arranged between a joint housing and a ball head. The shell is provided at one end with elastically deformable ribs projecting from a stop surface. So that the ribs, after compensating for production tolerances, can absorb, in the elastically deformable zone, additional axial shock loads occurring in driving operation, it is proposed that the ribs be designed as square ribs, running radially, and separated by grooves from the stop surface adjoining their side walls, while the volume of each rib projecting above the stop surface, before mounting, is approximately equal to the free volume of the two grooves adjacent to it, so that the side walls of the grooves lying next to the stop surface act in the mounted condition as support walls for the elastically deformed ribs.

Title: Improvements in or relating to tapes
Inventor: MAY GEOFFREY BILSON
IPC: B31B1/90
Filed: 1984-03-19
Granted: 1988-07-07
Abstract: A teartape for packaging materials, and particularly such materials based on polyolefin films, includes a base film coated with a pressure sensitive adhesive composition. The teartape is affixed to the packaging material by the adhesive composition. This avoids the problem of distortion which can occur when affixing conventional teartapes to such packaging materials by means of hot melt wax compositions. The teartape is applied to moving packaging material by controlling the speed of the teartape in accordance with the speed of the packaging material so as to reduce tension imbalance. The speed of the teartape may be controlled in dependence upon the tension in the teartape. This can be achieved by supplying the teartape from a dispenser having a brake means (4,5) and a drive means (10,11,12) for regulating the speed of the teartape in dependence on the tension in the teartape.
