Title: Vane-cell pump
Inventor: JURR RICHARD
IPC: F04C15/00
Filed: 1988-03-19
Abstract: In the case of a vane-cell pump, an outlet (11) is arranged in the region of the smallest crescent-shaped cross-section of the pump chamber (7). A snifting connection (13) leads from an inlet (9) up to a point, seen in the direction of rotation of the rotor (2), directly after the outlet (11) and, there, opens into the pump chamber (7). As a result, pressure medium can flow in behind into the widening crescent cross-section via the snifting connection (13), so that no underpressure arises there. <IMAGE>

Patent DE-3811974-A1 (DE)
Inventor: MUELLER FRANZ
IPC: F16B37/04
Filed: 1988-04-11
Abstract: The sliding nut (16) or sliding bolt is intended for insertion in C-rails (10) having edge webs (14) pointing inwards. In the assembled state, the edge webs (14) engage in longitudinal slots (22) in the nut (16) or in the bolt head. In a manner known per se, the longitudinal slots (22) are provided with projections which release deformations of the edge webs (14) when the nut or bolt is clamped against the C-rails. However, the special feature is that at least one projection is formed by lateral curving or such obtuse- or acute-angled deflection of the side wall of a longitudinal slot (22) that it bends an edge web (14) laterally in the form of an arc.

Title: Braces with hook tape in conjunction with trousers which are provided with a loop or attachment tape on the trouser waistband
Inventor: WEBER AUGUST
IPC: A41F3/02
Filed: 1989-02-01
Abstract: Braces (1) with a hook tape (2) in conjunction with trousers which are provided with a loop or attachment tape (4/4) on the trouser waistband (3) serve, according to the invention or innovation, to hold the trousers at the desired height on the body of the respective person. This takes place due to the fact that a tab (6) mounted on the band of the braces, for example, and consisting of a loop or hook tape (4/4), for example, or tabs provided with the abovementioned tape is/are pressed against the trouser waistband (3) which is provided (8), for example, with loop or attachment tape on the other side, an excellent effect being achieved by the firm attachment between the two parts. It is known that the braces currently commercially available or in use with the attachment elements, such as the usual clips, do not ensure secure attachment since the trouser waistband already slips out of the now customary attachment holder, for example out of the clips, at least after some use under little tension, which can cause an embarrassing situation for the person wearing the braces. This is very reliably prevented by the invention or innovation. <IMAGE>

Title: Process for the preparation of formic acid from carbon monoxide and water
Inventor: BROCKHAUS RUDOLF DR
IPC: C07C53/04
Filed: 1989-02-08
Abstract: To date, formic acid was prepared from carbon monoxide and water in two steps by carbonylation of a primary or secondary hydroxyalkylamine followed by hydrolysis of the hydroxyalkylformamide, only low conversion rates being achieved during the hydrolysis step. The novel process is intended to be more economical and to proceed under milder reaction conditions. The formation of formic acid from carbon monoxide and water proceeds in the presence of tertiary hydroxyalkylamines in high yields and under mild conditions. Preparation of formic acid.

Title: Blow-moulded wide-neck container of scarcely stretchable plastic, and attachment for the wide-neck container and process for producing the wide-neck container
Inventor: LEHNER ALWIN
IPC: B29C49/76
Filed: 1989-05-23
Abstract: The wide-neck container (10) can be produced from a scarcely stretchable plastic with a thread. This thread is formed as a recess (17). The blow mould (40) comprises two halves (41, 42). For forming a thread (17), a projecting section (45) in the form of a rib is provided on the mould. Arranged on both sides of the section (45) are depressions (47, 49), the width (b1, b2) of which is dimensioned such that the blowing pressure P of about 20 bar is adequate to force the plastic nicely around the projecting section (45). This produces the narrow thread (17). The depression (47) of the mould (40) corresponds to the region (48) underneath the thread (17), and the depression (49) corresponds to the region (50) above the thread (17). <IMAGE>

Title: Flat resistance heater used in presses - has rectangular section tubes contg. longitudinal elements in holder, spring plate resting on ribs, and top and bottom plates
Inventor: BUSSE HORST
IPC: B27N3/20
Filed: 1989-06-09
Abstract: A pressure-resistant flat heater plate, for use in hydraulic presses with wood, veneers, plastics, fabrics, acrylics, glass or polyesters, etc., consists of a number of rectangular or square section tubes contg. two longitudinal supporting ribs or smooth walls; the latter hold at least one electrical resistance heater element, with temp. regulator and sensor, an internal profile to mount the heater element, and a spring plate. The tubes are held in position by at least one top plate which is mostly covered with adhesive, and a bottom plate provides a stable structure. The element is insulated with 'Teflon'(RTN) or silicone, protected mechanically with impregnated glass cloth insulation; the top and bottom plates are pref. coated with thermoplastic PTFE. ADVANTAGE - The design provides a simple and inexpensive way of producing any heating required. The outer edge areas can be held at a desired temp., e.g. if only part of the whole sheet is actually used for the heating purposes.  The edge areas can be e.g. switched off and thus save costs. The arrangement allows short heating cycles to be used. The edge areas can be adjusted so as to provide uniform temp. over the whole area. Such a heater can be designed for virtually any voltage.

Title: Auxiliary yarn - supplied direct from ring spinning frame to winder for starter spools
Inventor: KAMP HEINZ
IPC: D01H9/02
Filed: 1989-08-03
Abstract: A process to wind starter spools straight from cops on a spinning frame is by crosswinding on to a former. On the ringframe, the service robot doffs the initial four spindles, and the number can be increased or reduced as required. These cops are sepd. into a magazine by means of an automatic trip device. The magazine (11) is transferred to the starter spool winder (10), adjacent to the end of the ringframe, which has the base (16) for the cop (3) when taken from the magazine (11), by conventional methods. The yarn (6) is guided (18) and is cleared and pieced as necessary in the usual manner (20,21), then wound on a former (4), engaged by the cross winding roller (17) and transferred by means of the arm (14) to the container (15), and at changeover a new former (4) is brought from the source (12) to recommence winding. ADVANTAGE - The amount of auxiliary yarn produced is better controlled without a separate plant for the purpose. The yarn is not twice processed, and so retains the same direction of wind, without running counter twist.
