Patent DE-3807499-A1 (DE)
Title: Diamond-coated sewing-machine needle tip
Inventor: ARNDT FRANZ MARTIN
IPC: B21G1/04
Filed: 1988-03-08
Abstract: Sewing-machine needle tips diamond-coated by electrodeposition provide an increase in performance in sewing by increasing the number of stitches and hence the sewing speed, and because the tip and the tip surface are harder and more wear-resistant due to the diamond armouring, there is a reduction in frictional heat. The electrodeposition, known per se, of hard chromium, for example, with the simultaneous inclusion of diamond dust particles provides a great increase in the hardness of the surface of the needle tip. In order to finish the tip, which is overdimensioned due to the electrodeposition, and in order, at the same time, to improve the surface finish and the tip itself even further, regrinding by means of a diamond wheel harder by several degrees of hardness is proposed.   If a hollow tip is used for electrodeposition, regrinding by means of a diamond wheel can be dispensed with since the congruent needle tip, which is smaller by the thickness of the layer, is centred in the hollow tip, without touching the latter, by means of a known clamping and guiding mechanism and, since the layer in the cavity consists of an electrolyte composed of diamond dust particles, it is electrolytically deposited on the tip surface. To further increase the number of needle stitches and the sewing speed, the use of heat-treated needle bodies is proposed, these being composed of a material from the hot-work steel series, e.g. 42 CrMo4 or the like.
Patent DE-3811953-A1 (DE)
Title: Slitting strip shears
Inventor: FRITZ MANFRED
IPC: B21B29/00
Filed: 1988-04-11
Abstract: In order to compensate for the deflection of the cutter shafts 5, 6 of slitting strip shears, bending control is applied by means of bending cylinders 16, 17 which act on fitted pieces 12, 13; 14, 15 lying one above the other and connected to one another in a tension-proof manner. The cutter shafts are firmly clamped with their journals 5a, 6a; 5b, 6b over a defined bearing length L in the fitted pieces so that bending moments are exerted on the cutter shafts via tilting moments of the fitted pieces. Load-induced positional changes of the cutting edges of the circular cutters 34 can be avoided by the bending control so that burr-free cutting edges can always be produced irrespective of the cutting forces. The deflection of the cutter shafts can be compensated for in a controlled manner by sensing the deflection of one cutter shaft 5. <IMAGE>

Title: Control of a testing head for material testing
Inventor: GRIMM WOLFGANG
IPC: G01N27/90
Filed: 1988-07-25
Abstract: The invention relates to a control of a testing head for material testing. For this purpose, the testing head is connected to an extension arm which is connected to sensors at both its ends. Each of the sensors is connected to a logic component. When the logic components determine, by mutual comparison, that the sensors are delivering unequal values, the extension arm, which can be rotated about an axis, is adjusted until a balance (equalisation) is produced between the logic components. This is the case when the sensors have the same surface separation, therefore when the extension arm and testing head lie at a tangent to the surface. The sensors used are preferably those of a pneumatic type, since these are not sensitive to small unevennesses of the surface, and even test objects with a low surface quality can thus be covered by these sensors.

Title: Method and machine for the series production of horizontally split casting moulds
Inventor: PEDERSEN JOERGEN PALM
IPC: B22C11/00
Filed: 1988-08-19
Abstract: A dividing plate (7) is mounted in a moulding machine of the DISAMATIC<(R)> type, between the press plunger (2) and the press abutment (4), thus forming two separate mould parts (13, 14), one (14) of which is pushed onto a tilting table (16) on which there is already a corresponding second mould part (13') formed in the preceding cycle. The mould part (13) formed at the same time is brought back together with the dividing plate (7) and the tilting table (16) is tilted in such a way that the dividing surface of the ball (14, 13') formed is horizontal. After the ball has been conveyed further, the tilting table (16) is swung back, the dividing plate (7) is removed and the mould part (13) formed at the same time is ready to receive a mould part formed in the subsequent cycle, which is pushed onto the tilting table. In this way, an already available machine can be modified by relatively simple means to produce moulds with a horizontal dividing plane, something which would otherwise require the acquisition of a completely new machine. <IMAGE>

Title: External speed indicator for a motor vehicle
Inventor: SCHMIDT ERNST-GUENTHER DIPL PH
IPC: B60Q1/54
Filed: 1988-09-09
Abstract: The external speed indicator for a motor vehicle is intended to indicate at any time the instantaneous travel speed at the outside of the motor vehicle, in particular at the rear of the vehicle. In order to permit an unambiguous association with the vehicle, the three-digital travel speed indicator is coupled to the number plate of the said motor vehicle and integrated into the body of the vehicle. The indicator will preferably consist of LCDs which are driven by a pulse shaper and pulse counter with digitised pulses. By virtue of the visual presentation of the travel speed of the motor vehicle in a way which is visible to everyone outside the motor vehicle, the driver is forced out of his anonymity. Since he then feels himself connected to his surroundings, he will adapt the speed of his motor vehicle to the conditions of his surroundings. Since a driver continuously has to observe the motor vehicle travelling in front of him, he is forcibly always made aware of the speed of his own vehicle.
