Title: Mfr. of needles for sewing machines - from continuous length of wire which is cut when needle points are ground
Inventor: PAVEL KLAUS
IPC: B21G1/04
Filed: 1979-11-28
Abstract: The needles for sewing machines are made from a continuous length of wire (A). The wire is fed through a stamping machine which forms longitudinal grooves (1) separated from each other by a distance (Z). A hole to form the eye (2) is then punched through the wire near the end of each groove (1). The wire is then cut into separate needles by grinding the points (6) at a distance (x) from the eye end of the groove (1). This operation leaves a square end (5) on the parallel shank (7) of the adjacent needle. The distance (Z) between grooves is chosen so that it is greater than the sum of the lengths of the point (6) and the shank (7) i.e. Z is greater than x + y.

Title: Multilayer sealable paper bag has inner lining sealed - while closure flap is folded back to expose layers to heat
Inventor: KUCKHERMANN GUSTAV
IPC: B29C65/14
Filed: 1979-12-21
Abstract: A method of sealing (welding) the inner lining of a multi-layer paper bag having a staggered closure flap comprises the following. The closure flap (4) fixed to the rear side of the paper bag is folded back about a fold line (5) set back (i.e. further down) from the edge (6) of the inner lining (3). While it is in this folded-back state, heat is applied to the exposed inner layer (3) to seal the superimposed layers together. The fold line (5) may lie virtually coincident with the edge (6). Infrared thermal energy may be used for the sealing, regulated as a function of the speed of passage of the bag. This method ensures better penetration of heat to the various thickness of paper than was possible without the folding back of the flap. Thus prodn. rates can be increased.

Title: H-section sheet pile made of steel and method of producing it
Inventor: EHIRO TAKASHI
IPC: E02D5/04
Filed: 1981-01-27
Abstract: An H-section sheet pile made of steel has connection parts at the ends opposite one another of its flanges opposite one another, the centre line of the cross-section of this H-section sheet pile running between the two flanges. One pair of connection parts are provided at one side or diagonally symmetrically with regard to the centre line and are designed as finger connection parts, whereas the other connection parts, which are opposite the said pair of connection parts, are designed as overlapping connection parts. To produce such a sheet pile, an H-shaped blank, which has at each end of its flanges a socket and two projections subsequently forming the connection parts, is rolled in grooves in order to reshape an H-shaped blank of symmetrical dimensions in the vertical and lateral direction into an asymmetrically formed H-shaped sheet-pile blank by the geometric relationships between a web and the flanges being shifted. The rolling is continued with other grooves in order to form a socket as well as projections at one end of a flange.

Patent DE-3104876-A1 (DE)
Title: Antilock brake pressure control circuit
Inventor: SAUMWEBER ECKART DR ING DR
IPC: B60T8/1761
Filed: 1981-02-11
Abstract: An antilock brake pressure control circuit for vehicles is proposed, in which an analysing circuit monitors the rotational behaviour (speed, acceleration, slip) of at least one braked wheel and from this derives brake commands such as rapid or slow pressure increase or pressure reduction or pressure maintenance for brake actuating elements. In order to obtain the shortest possible braking distances the analysing circuit is designed so that in a "starting phase", that is after an initial braking, that is a brake pressure increase following unbraked travel, the existing brake pressure is kept constant if the wheel acceleration is less than a predetermined (negative) threshold value. If this negative threshold value is re-exceeded, the brake pressure is further increased until the wheel acceleration is again less than the negative threshold value. The starting phase is terminated only when the wheel acceleration is less than a further, quantitatively much greater (negative) threshold value or when a further criterion indicates an inadmissibly high slip or a very low wheel rotation speed of the monitored wheel. On completion of the starting phase the brake pressure is again varied as a function of the detected wheel rotational behaviour.

Title: Process for producing molten silicon-containing master alloys
Inventor: BUCHWALDER JOACHIM DIPL ING
IPC: C22C33/00
Filed: 1981-04-25
Abstract: The invention relates to a process for producing molten silicon-containing master alloys in induction furnaces. Such alloys are required as silicon carriers for alloying molten crude iron, cast iron and steel with silicon. It is the aim of the invention to reduce the consumption of electric power in the smelting of such alloys and to increase the smelting output and the mass throughput. For this purpose, the object is to utilise a part of the heat of solution of silicon in iron for heating the melt. Starting from the established relationships between the enthalpy of solution of silicon in iron and the silicon concentration in the iron-silicon alloy, solid ferrosilicon having a silicon content of >/=45% and iron-containing components are used and smelted according to the invention in such a mutual mass ratio in the induction furnace that a reduction in the silicon/iron ratio in the total mass of the furnace charge down to values of 0.5, preferably 0.8-0.9, as compared with the silicon/iron ratio of the ferrosilicon used, is ensured.

Title: Plectrum with transverse tip for plucked instruments
Inventor: ZOERMER WILFRIED
IPC: G10D3/16
Filed: 1981-05-23
Abstract: The invention relates to a plectrum with a transverse tip offset at right angles to the holding surface for playing plucked instruments. All plectra available commercially are played by being pressed with the flat side against the strings which they thus tension and make shoot forwards. In addition to the very sharp sound, they produce many additional noises and, as a result of the impact with the wider side, are the source of varied playing errors. This problem is solved according to the invention by the plectrum being structured in two parts: the holding surface - indicated respectively in the drawing by "A" - and the transverse tip - indicated respectively in the drawing by "B". Holding surface and transverse tip penetrate one another at an angle of 90 DEG . Now, the tip of the plectrum slides over the string on impact instead of pressing it to the side, which produces a clearer sound and makes possible error-free playing because it is friction-free. The main area of use of the invention is in mandolin-playing and in guitar-playing in particular in modern light music. <IMAGE>
