Patent DE-3909310-A1 (DE)
Title: Contact pin
Inventor: KOLB RUDI
IPC: H01R12/58
Filed: 1989-03-21
Abstract: A contact pin (10) has a push-in section (14) and a transition section (16) which leads to the square shank (10). In the region of the push-in section (14), the contact pin (10) is broadened by means of two lateral, longitudinally running ribs whose side surfaces form contact tracks. In the transition region (16), the width of these ribs is reduced towards the shank (10). The height of the ribs is likewise reduced, since the base surface (28) of the ribs runs obliquely upwards. As a result of the clearly smaller running-in surfaces (insertion surfaces) in the transition region (16), the insertion process is simplified and the risk of swarf forming is reduced. By reducing the wall thickness in the transition section (16) on the top-side edge regions, and by reducing the base thickness in this transition region, the elasticity is increased, which makes elastic deformation possible. <IMAGE>

Title: Adhesive components sepd. by axial partition in cartridge - are mixed during expulsion with partition retracting into plunger cavity
Inventor: LEHLE PETER
IPC: B05C17/01
Filed: 1989-04-24
Abstract: Two components of a mixt., esp. an adhesive, are held in the sections (7,8) of a hollow cylinder and normally kept apart by an intermediate partition (2). A descendable plunger (6) in the cylinder forces both components into a nozzle (9), wherein the component are mixed, e.g. using an internal aperture worm, for discharge from the nozzle end. The leading end of the plunger has a diametrical slot (3) through which the partitions progressively passes to accumulate in a hollow chamber (5) within the plunger, whose leading edge acts as a cutter. ADVANTAGE - Both mixt. components are jointly mixed and discharged from the cartridge by a single plunger movement.
Patent DE-3914095-A1 (DE)
Inventor: AHLBORN GUENTER
IPC: B61F5/36
Filed: 1989-04-28
Abstract: The invention relates to the linkage of the running gear 2 and 3 and the frame 1 of a railway vehicle with wheel sets clamped securely via axle bearings in a running gear frame 4 and 5, the frame 1 being linked to the running gear frame 4 and 5 via leaf carrying springs 6 and open link suspension 7 without a bogie pin and a frictional rotation restrictor 8 being arranged between the running gear frames 4 and 5 and frame 1. The object of the invention consists in designing the link between the running gear 2 and 3 and frame 1 in such a way that, even when the axle is partially or completely relieved of load or the axle suspension loads, the leaf carrying springs 6 of the running gear 2 and 3 and thus the suspension of the open links 7 are stressed to such an extent that a sufficient restoring effect and a sufficiently large rotational restriction of the running gear 2 and 3 are maintained. This object is achieved in that, between running gear frames 4 and 5 and frame 1, a spring 10 is arranged which clamps said frames to one another and is acted upon inversely proportional to the stress of the leaf carrying springs 6 of the running gear 2 and 3. <IMAGE>

Title: Mfr. of conical bags from plastics film - involves oblique welding and cutting of double layer of plastics film strip
Inventor: LAMBRECHT EMIEL Y
IPC: B31B160/10
Filed: 1989-08-24
Abstract: Conical bags are produced from a continuous strip (3) of a double layer of a thermo-plastic. The strip (3) is guided between two endless belts (6, 7) under two welding and cutting heads (1, 2). These cutting heads are aligned obliquely in opposite directions to a plane transverse to the longitudinal direction of the strip (3). The strip is thus cut into trapeziums with the cut edges of the upper and lower layers welded together. The endless belts (6) and (7) are guided by pulleys so that they are not in the way of the welding and cutting heads. USE - Mfr. of conical bags from plastics film.

Title: Pressure roller - has radially spreading clamps to fix hollow cylinder to roller body
IPC: F26B13/14
Filed: 1989-12-09
Abstract: In the roller assembly for processing web material, such as polishing or compressing or embossing, the hollow cylinder (3) is secured to the roller body by two radially spreading clamps (10,11). They are secured by clamping screws at their end faces. The clamps (10,11) are located in the centre zone of each roller half-section. Pref. the clamps (10,11) each consist of clamping sleeve (13,16), coaxially above each other and open on the long sides.  Opposing clamping rings (17-20) are between the sleeves in a mirror image layout, where the facing surfaces of the sleeves (13,16) are conical and the cross section of the clamping rings (17-20) against them is also in a matching conical shape. A number of clamping screws, spaced equidistantly on a circle, are passed through to clamp them together. Axially parallel channels between the clamping screws carry a fluid heat carrier medium. Open gutters are worked into the surface of the roller body, equidistant round it, running longitudinally.  A guide for the fluid heat carrier medium is in the coaxial intermediate zone (2) between the roller body (1) and the hollow cylinder (3), as a guide plate (22) fixed to the roller body (1) in a spiral, to rotate with the body (1). ADVANTAGE - The assembly gives the roller a bending action even at high pressures, without the need for large roller dias.  or thick roller mantle walls.
Patent DE-3942096-A1 (DE)
Title: Car hydraulic steering servo
Inventor: KAHRS MANFRED DR
IPC: B62D5/093
Filed: 1989-12-20
Abstract: The steering servo cylinder (6) is controlled via a proportional valve (150), whose two sections are linked by sprung elements. The valve is operated w.r.t. the mechanical force on the steering, and operates above a set force. The sprung element is inhibited, or the set pressure increased, by a linkage to the vehicle speed related monitor. A servomotor in the correction linkage can alter the sprung setting of the spring element, thus effectively increasing the pressure threshold above which the servo effect operates.

Patent DE-4023636-A1 (DE)
Inventor: SCHABERT HANS-PETER DIPL ING
IPC: F16K31/04
Filed: 1990-07-25
Abstract: In order to protect a spindle (2) rotated in a fitting by a spindle nut (6) rotating in a housing (4), the invention calls for a braking device for the spindle nut (6). When a given reference force is exceeded, two facing friction surfaces (11, 13) are pressed towards each other against the spindle (2) to exert a braking force. One friction surface (13) is rotationally secured with respect to the spindle nut (6), while the other friction surface (11) is rotationally secured with respect to the housing (4). The invention calls for the spindle nut (6) to be spring-mounted by a spring washer assembly (50, 51) in at least one longitudinal direction, the braking force acting through this assembly on an intermediate radius (ro) relative to the width (r1 - r2) of the assembly. The fraction of the total spindle force which acts as a braking force is thus increased.
