Title: IC engine fuel injection engine timing adjustment - has lugs on coupling profiled to give uniform speed response
Inventor: SCHEYING HEINZ
IPC: F02D1/16
Filed: 1977-06-16
Abstract: A coupling has a disc (2) driven from the crankshaft and a disc (3) which drives the injection pump. The crankshaft disc has two lugs (4) diametrically opposite each other and the pump disc has two lugs (5) diametrically opposite each other. The lugs on the crankshaft disc drive the lugs on the pump disc through rollers (8, 9). The lugs have curved surfaces (7, 6) and as the speed increases the rollers move on these under centrifugal force. This forces them apart against the action of two springs (10, 11) and adjusts the relative positions of the pump and crankshaft. The surfaces (6, 7) on both lugs have similar curvatures but about different centres. This gives a more even response characteristic over the whole range of speeds.

Title: Sample analysis by bombardment with electromagnetic radiation - with conductive layer in region of sample for uniform potential distribution
Inventor: HILLEKAMP FRANZ PROF
IPC: H01J37/252
Filed: 1977-07-21
Abstract: A sample is analysed by bombardment with electromagnetic radiation, causing it to emit particles which are subsequently analysed in a co-ordinated mass analyser, using appts. comprising an evacuated housing, a sample support within the housing and one or more layers of electrically conductive material in the region of the housing. The conductive layer and sample may be electrically insulated from other components in the region and can be maintained at the same potential, or the conducting material is itself insulated and, in operation, may be at a potential different to that of the sample. The layer(s) may, in operation, serve to trap ions or electrons formed by the irradiation and are so used to generate calibration signals. The conductive layer ensures a uniform potential distribution in the region of the sample, so that potential difference for all the ions emitted from the sample and accelerated towards the mass analyser is constant. The sample can be maintained at a desired potential, external interfering potentials are prevented from reaching the analysis site, and calibration signals can be generated.

Title: Subscriber circuit with AF pushbutton selection for PBX - has special-facility buttons each used twice depending on whether handset is lifted or not
Inventor: GLEMSER JUERGEN DIPL ING
IPC: H04M1/53
Filed: 1978-04-15
Abstract: A pulse generator (IS) is controlled either by special-facility pushbuttons (ST) or from the normal selection keyboard (WT). The special-facility buttons allow various additional facilities like enquiry calls, rerouting, intervention, conferencing etc. to be activated by pressing the appropriate special-facility button - which causes an appropriate sequence of pulses to be generated. The special-facility buttons are arranged so that special facilities can be activated even without lifting the handset. Normally an even number of pulses is generated when a button is pressed. With the handset not lifted whichever is the last pulse is not generated by the subsequent and continuous loop-break so that an odd number of pulses is produced. This odd number activates those special facilities appropriate to an unlifted handset. The special-facility buttons can be used twice e.g. for direct connections to an attendants set in the private branch exchange system or to an extension. The user only has to operate the button for the wanted special detected by a centralised sampling device by counting. Since the pulses generated are temporarily independent of the user's behaviour, the centralised detector can be set to fixed values.
