Title: Fail=safe control valve for dual circuit - has control piston moved aside on failure of one circuit for unmodulated braking
Inventor: WEIL WOLFGANG
IPC: B60T11/34
Filed: 1976-10-02
Abstract: The control valve is used for a pair of dual braking circuits. It has the main control piston (3) operated by a separate piston (12) linked to the servo force (Q) which determines the pressure at which the piston modulates one of the circuits (rear brakes). No special sealing gaskets are required between the controls for the circuits. If there is a failure of the servo control force, the second piston is displaced to one side of the housing. It comes up against an end stop (14) so both circuits operate without any modulation.

Title: Boring bar system with clamped cutter - has transverse clamping screw at acute angle to cutting tool plane
Inventor: HERTEL GUENTHER
IPC: B23B51/00
Filed: 1976-10-15
Abstract: The boring bar has a longitudinal end slot for holding a cutter. The jaws formed are clamped by a diametral screw against the cutting tool. The tool is held purely by clamping force and without any holding profiles. The end of the cutting tool has a central projecting lug. The lug projects into a central seat (17) between the clamping jaws (3, 4). The clamping jaws engage with contact faces at the projection. The clamping screw (30) is arranged so that its axis passes through the boring bar axis yet it is at an acute angle to the mid plane of the flat cutting tool. This screw does not pass through the cutting tool.

Title: Anti-theft alarm for vehicle - has door and mercury switches connected to circuit which pulses horn and indicators
Inventor: LARISCH MANFRED
IPC: B60R25/10
Filed: 1976-10-26
Abstract: The alarm control unit in the boot links door, boot and bonnet switches with mercury switches positioned to close if either side or end of the vehicle is raised, the latter being disconnected for hill parking. A latching switch on the boot lock sets the alarm, which is switched off by using the boot key. The alarm cuts off the ignition and pulses the horn(s) and direction indicators at intervals up to 30s. An additional switch prevents feedback from the indicators to the horn when the alarm is not in use.

Title: Sack filling unit esp. for packaging particulate materials - is designed to minimise entrapment of air with particles during packaging
Inventor: GROSS LUZZI
IPC: B65B1/20
Filed: 1977-03-03
Abstract: A sack filling unit is esp. for packaging particulate goods. It is designed to minimise the entrapment of air during packaging by colapsing the fully opened sack prior to filling it and then opening it at such a rate that the free volume created in the sack approximates to the volume- or weight-increase of the goods being packaged. The sack is collapsed and opened with the aid of movable boundary units (11). Once the sack has been filled it opening is closed just far enough to prevent the foods from escaping but still allow any entrapped air to be at least partly removed by controlled compression of the sack.

Title: Safety glass using polycarbonate between two glass panes - where polycarbonate has undulations compensating for differences in thermal expansion
Inventor: LESSAU KURT
IPC: C03C27/12
Filed: 1977-03-16
Abstract: Composite pane. using two outer layers with the same coefft. of thermal expansion (CTE), which are bonded via two elastic, intermediate layers to a middle layer. The middle layer has a pattern, raster or grid formed by lyre-shaped folds which completely absorb the dimensional difference arising during the heating or cooling of the pane, due to the difference between the CTE of the middle and outer layers. The dimensional alteration of the pane thus depends only on the outer layers. The folds may consist of 1 or 2 undulations, so they intersect the centreline of the middle layer three or five times; alternatively, shallow fold may be used which does not intersect the centreline. The outer layers are pref. silicate glass, and the middle layer pref. polycarbonate, although other materials may be used. The grids are pref. square or rectangular with length or breadth 100-500 mm. Safety glass, e.g. for shop windows, or for insulation and other purposes can contain polycarbonate located between two glass panes without problems arising due to the difference in CTE.

Title: Warning device for motor vehicle drivers - has signalling columns with liq. crystal display units showing warning signals and connected to telephone line
Inventor: NEUMANN DIRK DIPL ING
IPC: G08G1/07
Filed: 1977-04-04

Each emergency call column has at least one signalling device with a liq. crystal display unit. Voltage necessary for the liq. crystal excitation is generated by the d.c. supplied to the signalling device. In case of danger a control signal is applied to the device, which causes the d.c. voltage application to the display unit.

Title: Polyethylene foil adhesive and printing ink receptivity - is improved by ionic etching of surface
Inventor: TILGNER RAINER DR
IPC: B29C59/14
Filed: 1977-09-30
Abstract: Polyethylene foils have their surfaces roughened to improve their receptivity w.r.t. adhesives or printing inks by exposing the surfaces to ionic etching. Pref. the ionic etching is carried out using O2 which has been rendered active by high frequency activation. Period of etching may be varied from 5-20 mins. Ionic etching leads to uniform surface roughening in which the punctiform depth is 0.1 mu. Roughening results also in promotion of formation of permanent bonding gps. Ionic etching improves the receptivity without impairing other characteristics of the foils.

Title: Filament fault detection - uses a modified slitted cleaner which pivots to trip a switch if thickened filament fouls the slit
Inventor: FOGGER JOACHIM KOELN
IPC: D02J7/00
Filed: 1978-02-11
Abstract: The process to eliminate faults in filaments of fibrous polymer has a detector to monitor the feed yarn. If a fault is registered, then a warning signal is generated and it is cut between the feed and the winder, and sucked clear. The filament material passes through a modified slitted cleaner which, in the event of a fault, is tipped and trips a micro-switch, and the filament is severed by the effect of a restraint at the detector. Process is designed partic. for texturised yarns developed by the simultaneous draw-texturising process, the unit eliminates faults through a build-up of fluff and debris.

Title: Multiple, automated immunoassay method - with reaction carried out in removable open=ended syringe tips
Inventor: MILES LAUGHTON E
IPC: G01N33/543
Filed: 1978-02-15
Abstract: Determination of the amt. of analyte (A) in a sample, where (A) is one of a pair of specific bindable substances, and one member of the pair is insolubilised, uses as detectant (D) one member of the pair giving a measureable signal proportion to the number of molecules of (D) present. The improvement is that first a soln. or (A) is drawn, by syringe, into an open-ended tip, detachably mounted on the syringe, which contains the insolubilised component. (where (A) can be bound to the tip it may be the insolubilised component). A soln. of (D), and other reagents or wash solns. is supplied to the tip (from an outside source or from the syringe), then the solns. removed from the tip by the syringe. The amt. of (D) insolubilised in, or remove from, the tip is then measured to determine the amt. of (A). Process is esp. for immunoassay procedures such as radioimmunoassay (RIA), immunoradiometric assay (IRMA) or 2-site IRMA. The system requires minimal supervision and avoids fluctuating conditions.
Patent DE-2811329-A1 (DE)
Title: Multicomponent twisted yarn - uses open=end spun yarn for twisting with two other components
IPC: D01H13/30
Filed: 1978-03-16
Abstract: The process to develop a twisted yarn for use in bielastic woven fabrics, for covering foam-clad furniture, uses an open-end spinning unit to spin the yarn to be bound in with the other two natural, synthetic and/or elastomeric threads so that they are twisted together. The system allows the use of open-end spun yarns, without the elastomeric component showing, in a fabric which can be treated thermally without damage. An adhesive agent is applied to the threads so that they bind together on twisting. The open-end spun yarn is opened out by hot steam in an underpressure of 0.1-0.2bar, and its surface is swollen in water at 70 degrees C for 10 minutes. A ketonic or halogenalcan organic solvent can be added to the loosening agent. The threads to be twisted together are delivered by separate spools in a common plane and parallel orientation, while a delivery cylinder is used to give a forward slip of 350% to the elastomeric thread to control the unwinding. Polyacryl nitrile fibres are pref. used for the open-end spun yarn.
