Patent DE-2809807-A1 (DE)
Title: Graphitisation modifier for cast iron - comprising silico-Mischmetal and coke, reducing cementite formation at thin walled casting surface
Inventor: PEREGUDOV LEV V
IPC: C21C1/08
Filed: 1978-03-07
Abstract: The iron modifier has the compsn. (by wt.) 25-50% Si, 20-40% rare earth metal(s), 10-30% C, 0.1-0.3% S, balance Fe, It is added to molten iron in the form of a mixt. of 70-90wt.% silico-mischmetal and 30-10wt.% foundry coke. The modifier is added in amt. 0.3-0.5wt.% to molten iron to allow the prodn. of thin-walled castings without the formation of cementite on the cast iron surface in sandloan moulds. This improves the machinability of the castings and reduces prodn. costs by eliminating high temp. annealing to improve properties of the surface of the casting. The modified has a high graphitising ability because the carbon does not have time to dissolve completely in the iron before casting. Additionally, sulphur reacts with the rare earth metal in the modifier, producing high m.pt. sulphides which act as graphitisation nucleation centres.

Title: Moccasin type shoe with great flexibility - has pliable welt adapting to curve of bead in upper, reducing strain on seam
IPC: A43B13/14
Filed: 1978-07-08
Abstract: The moccasin type shoe has a flexible upper (4) a sole (1) and a welt (2) which except for the heel part is connected to the upper by a seam (3).

This pliability prevents pressure points on the foot and great strain on the seam so that the shoe is longer lasting. The welt is preferably made of natural leather with its rough inner side (12) facing the outer sole.

Title: N-channel memory FET with controllable gate - has window, or gap, on control gate over storage gate, or on protrusion on either side of optically quenched channel
Inventor: ROESSLER BERNWARD DIPL ING
IPC: H01L29/788
Filed: 1979-09-24
Abstract: The float-type storage gate of the field-effect transistor is surrounded on all sides by an insulator. The storage gate is charged with electrons by channel injection, and is intended for an optically quenched PROM in a TV transmission system. The control gate (G2), above the storage gate (G1), and/or the upper projection distant from the substrate, of two such projections provided on the storage and control gates, laterally of the channel, has at least one window, or a gap (BF, Bf) on the mutually overlapping projection parts. The storage gate is discharged by short-wave electromagnetic radiation. A normal substrate (Su), or the source (S) potential is applied to the control gate, to which the radiation (UV) is applied, as well as possibly to the storage gate via the window. Thus the effect of the control gate potential on the discharge velocity of the storage gate is increased, which in turn enables shorter irradiation periods.

Title: Electrophotographic colour TV tube screen production - has negative photoconducting layer under sensitised positive layer to produce wider stripes
Inventor: JUNGINGER HANS-GEORG DIPL PHYS
IPC: H01J9/227
Filed: 1979-11-10
Abstract: The electrophotographic method is used for coating the inside surface of a colour TV tube with the screen material and of using a shadow mask with slit widths up to twice the width of the phosphor stripes. Details of the phosphor strip widths and relationship to shadow mask dimensions are given together with the permissible tolerances. The method uses a negative electrophotographic process so that on the front glass (2) is an electrode (9) followed by a negatively charged photoconducting layer (10) and positive charged phosphor material (13) developed in the dark, shadow, area of the photoconducting layer (10). The width of the dark,shadow, area is determined by the mesh width (14) in the shadow colour selection grid (4) and not the slit width. The transmittance of the shadow mask is increased by about 50 percent if required. The exposure of the front surface material is by means of ultraviolet light to produce the phosphor pattern. The method enables narrower margins to be achieved than with wet processes.

Title: Bridge rectifier energy saving switch - has manual engage with electromagnetic holding winding for complete bridge operation
Inventor: GREISINGER GEB KRAUS
IPC: H01H47/04
Filed: 1980-03-11
Abstract: The energy saving switch for a bridge rectifier circuit is arranged so that half the bridge may be disconnected when power demand is low. In order to reduce the energy required by the switch itself (1) the circuit design uses a manually operated, electromagnetic holding winding switch (1) to connect two rectifiers (GL1, GL2) into the bridge (GL1, GL2, GL3, GL4) circuit. The switch (1) has a normal rest state 'off' position to which it automatically returns when the power requirement from the circuit drops. The continuous power drain from the circuit is supplied by two rectifiers (GL3, GL4). The switch design may be multipole, double throw as required. As a half bridge the effective output voltage, half that of a full bridge and is also proportional to peak voltage.
