Title: Sealing system for automobile vibration damper - has O=ring pressed against disc by garter spring to accommodate radial movement
Inventor: SCHMIDT RUDOLF
IPC: F16F9/36
Filed: 1980-09-18
Abstract: A telescopic vibration damper forming part of an automobile suspension system has a piston (6) which slides in a cylinder (1). The piston is guided by a bush (5) with a clearance which permits a degree of lateral movement. The piston is fitted with an inner sealing ring (7) with a flexible sealing lip (8) which is pressed against the shaft by a garter spring (10). The sealing ring abuts against a carrier ring (13) which houses a support ring (9) and an O ring seal (12). The O-ring is pressed against the face of a disc (11) which supports the outer sealing ring (14) and is retained by the end wall of the outer housing (3). This design of seal allows the O ring (12) to move radially over the face of the disc (11) and so accommodate any radial movement of the piston.
Patent DE-3037559-A1 (DE)
Title: Heating of multilayer metal tube - using alternate external and internal heating so temp. gradient through tube wall does not exceed permissible value
Inventor: LANDGRAF HELMUT DIPL PHYS
IPC: C21D9/08
Filed: 1980-10-02
Abstract: The tube consists, at least in part, of several layers, made e.g. by winding, where the metal layers are sepd. from each other by a layer (a) with lower thermal conductivity than the metal; and layers (a) are pref. of different thickness. The tube is heated by a stream of hot gases which is applied temporarily to only one side of the tube. The temp. of the heating gases is controlled by the difference (d) between the external and internal temps. of the tube so the value (d) does not exceed a prescribed amt. Heating is pref. used alternately on the external surface and in the bore of the tube; and the change-over between these two methods is pref. made when the value (d) is reached. If these tubes are heated too rapidly from the outside, the outer layer expands more than the inner layers and forms ring bulges. The same defects can occur in the bore of the tube when excessive heating rates are applied by internal heating. When air is present between layers of metal, bulges are extremely likely to occur. The invention provides the max. heating speed without damaging the composite or multilayer tube.

Title: Automatic shut-off for bulk goods pipe line - uses fall in pressure per unit of time to operate shut-off valve via membrane
Inventor: LESK ADOLF
IPC: B65G53/66
Filed: 1980-11-07
Abstract: The automatic shut-off is for a pipe line for pneumatically emptying bulk goods pressure containers, esp. where these operate with changing pressures, as in the case of tanker vehicles. The fall in pressure per unit of time is used to operate the shut-off valve and this is actuated by a membrane with or without the use of an electric switch. The delay in operating the air pressure valve may be adusted by altering the throttle effect in the air pipe line to the membrane housing.

There are one or more balance weights driven by a crank from the crankshaft and guided by a link rocking on the crankcase. The crank drive comprises a cylindrical disc (2) eccentrically-driven by a crankpin (1) and turning in a cylindrical bearing bore (7) formed in a link (3). Additional weights (23) can be formed at the bore end of the link, and there can be apertures (6) at regular intervals round the disc, one of these being diametrally opposite that accommodating the crankpin.

Patent DE-3100273-A1 (DE)
Inventor: KOERTVELYESSY LASZLO VON DIPL
IPC: G05D23/19
Filed: 1981-01-08
Abstract: Fail-safe and drift-free temperature controller Temperature controllers mostly have a drift because the sensor acquires a leak in the protective tube. The digital temperature controllers are substantially more stable, but a drift can also arise in them. The invention is based on the observation in practice that the probability of a simultaneous error of the same magnitude in two mutually independent systems is very low. A comparator that is connected between two temperature controllers raises an alarm when the two temperature displays differ too strongly from one another. Advantages of the invention accrue, in particular, when the measurement points of the sensors are very close to one another, as a result of which the temperature difference always remains very small. The comparator raises the alarm or switches the furnace off when one of the two systems experiences a failure or even a small unexpected drift.

Title: Closure sleeve for strappings around packaged goods
Inventor: GUGGEMOS XAVER
IPC: B65D63/14
Filed: 1981-07-08
Abstract: A novel closure sleeve for strappings around packaged goods uses an insert plate (36) which is secured in the sleeve (30) against slipping, for example, by lateral projections provided at the ends or by laterally protruding tabs which are arranged on one longitudinal edge and engage in cutouts which are provided in an upright section (18) of the longer of two legs of the sleeve (30). The insert plate is roughened or corrugated on both sides and is situated between the two strap sections within the sleeve, and, as a result, the relatively smooth strap surfaces are prevented from touching one another. The novel insert plate results in a considerable increase in the tensile strength of the sealed lead seals. <IMAGE>

Title: Linkage for the control of an internal combustion engine
Inventor: PAPENHAGEN DIETER
IPC: B60K26/04
Filed: 1982-04-21
Abstract: In the case of known linkages with a longitudinal shaft for the control of internal combustion engines flexibly supported in motor vehicles there is a risk of engine bucking which is to be suppressed by a costly bucking damper. In the case of the subject of the invention the bucking is prevented in that the longitudinal shaft is supported by means of a lever with the insertion of a spring on a part fixed to the engine. The return force of the spring, increased in the event of a bucking-like movement of the accelerator pedal and thereby of the longitudinal shaft, is cancelled with a retardation by the movement of the part fixed to the engine which is triggered by the increase in the torque of the engine. The opposing movement of the accelerator pedal and the engine movement restrict one another so that engine bucking is prevented.
