IPC: C08L7/00

Abstract: In the cross-linking of polymers containing ethylenic unsaturation, especially natural and synthetic rubbers of the isoprene or styrene-butadiene series, S-acyl derivatives of N-substituted thiohydroxylamines, previously known to be useful as accelerators for vulcanisation by sulphur or sulphur donors, can be used themselves as sole vulcanisation agents. 
     The preferred compounds for this purpose are the N-dithiocarbamoyl derivatives of amines, amides or imides, e.g. S-(N',N'-dimethylamino)-N,N-dimethyldithiocarbamate, S-(acetylamino) N,N-diethyldithiocarbamate or S-(phthalimido)-di-n-butyldithiocarbamate. Typical advantages of the resultant rubbers are better resistance to heat ageing and resistance to compression set when compared with sulphur cured rubbers and greater processing safety than TMTD-cured rubbers.

Abstract: Fuel injection apparatus for mixture-compressing internal-combustion engines with applied ignition and continuous injection into the intake pipe (1), in which a measuring element and a throttle flap (2) actuable as desired by means of an accelerator pedal are arranged in series and the measuring element is moved counter to a restoring force in accordance with the air quantity flowing through and in the process adjusts the movable part of a metering valve, arranged in the fuel line (13, 14) and comprising one differential pressure valve (3, 4) per cylinder of the internal-combustion engine, for metering in a fuel quantity proportional to the air quantity. In order to improve the exhaust emissions, the fuel consumption and the operating behaviour of the internal-combustion engine in the warm-up phase, the throttle is a nonadjustable restrictor (23) and, to influence the pressure difference as a function of the position of the accelerator pedal, a variable restrictor device (29, 34) is provided which can be influenced by a control arrangement (30, 30-, 30A, 37, 55, 70) in such a way that the pressure difference at the differential pressure valves (3, 4) is increased in the case of acceleration during the warm-up phase of the internal-combustion engine and, as a consequence of the resulting enrichment of the fuel quantity, a richer fuel/air mixture is brought about. <IMAGE>

Zur Verbesserung eines Vibrators dieser Art dahingehend, daß eine größere Montagefreundlichleit gegeben ist, wurde errlindungsgemäß vorgesehen, daß die Unwucht (10) auf der Welle (5) lose angeordnet ist. Dabei ist es auch zweckmëßig, wenn die die Unwucht (10) unter Anlage an die Welle (5) diese mindestens teilweise umschließend vorgesehen ist. Wenn gemäß einer weiteren Ausgestaltung der Erfindung die Unwucht (10) halbzylinderförmig ausgebildet ist und an beiden Enden Lagerschalen (12) aufweist, haben diese im Verhältnis zur trägen Masse der Unwucht geringes Gewicht und dienen lediglich der Umschließung der Welle und Gewährleistung einer Berührungsfläche oder Berührungslinie. Längs dieser besteht beim Anlaufen des Vibrators eine geringe Reibung, durch welche die Unwucht geringfügig in Drehung versetzt wird. Es ist auch der Einsatz leichterer Lager hierdurch möglich.

Title: Hammer arrangement and control for dot band matrix printer
Inventor: THORNE WILLIAM DUNCAN
IPC: B41J2/31
Filed: 1982-11-23
Abstract: @ The present arrangement is applicable to dot printers which comprise a continuously moving band (2) bearing dot font members (3) and a plurality of hammers (1) arranged to strike the band (2) at font member positions under the control of separate actuation mechanisms respectively by associated with the hammers. The hammers are associated by pairs, each pair covering a space equal to the spacing between adjacent font members. The odd and even hammers of each pair form two groups A and B. Controls are designed to assure that hammers in one group cannot be fired at the same time hammers in the other group are being fired. This greatly increases the clearance and makes possible setting the pitch of the front members to be exactly equal to twice the exposed individual hammer face width.

Abstract: The metering pistol is based on a manually actuated positive-displacement pump having a cylindrical housing (1), a product space (2) and a thrust rod (3) with the handle (5). By pulling on the handle (5), the amount of liquid located in the product space (2) is displaced and emerges forwards through the central bore (19) in the thrust rod (3). The product space (2) is sealed with respect to the housing (1) by means of a funnel-shaped rubber diaphragm (10) which can resist medicines and solvents. Non-return valves (22, 20) are arranged at the input and output of the product space. The seal of the product space (2) ensures, by means of the funnel-shaped diaphragm (10), that the metering pump is absolutely tight so that no liquid can emerge outwards. In addition, a long lifetime is ensured by means of this design. <IMAGE>
