Inventor: BUTTERWORTH DAREN
IPC: G01V3/11
Filed: 2017-09-27
Granted: 2023-11-23
Abstract: The method allows testing a metal detection apparatus (9) with entrance and exit 
apertures (2A, 2B) adjoining a transfer channel (90) along which products (P) are 
movable through a coil system (6) that defines a detection zone (60) and comprises 
a transmitter coil (61) and a first and a second receiver coil (62, 63) dimensioned 
such that a current applied to the transmitter coil (61) induces a first coil signal in the 
first receiver coil (62) and a second coil signal in the second receiver coil (63), that 
do not compensate one another when metal (C) is present in the transferred 
products (P), which causes an input signal within a signal processing path (4, 5) of 
the metal detection apparatus (9), and with at least one test device (7) that 
comprises at least one test article (79) that is movable through the detection zone 
(60). The method comprising the steps of moving the test article (79) through the 
detection zone (60) along a first transfer axis (ca) and measuring a first input signal 
for which a first threshold (th1) is determined such that the amplitude of the first input 
signal exceeds the first threshold (th1); moving an identical test article (79) through 
the detection zone (60) along a second or further transfer axis (ta; ... ) and measuring 
a second or further input signal for which a second or further threshold (th2; ... ) is 
determined such that the amplitude of the second or further input signal exceeds the 
second or further threshold (th2; ... ) and selecting said first, second or further 
threshold (th1; th2; ... ) in the signal processing path (4) whenever the test article (79) 
is moved along the related first, second or further transfer axis (ca; ta; ... ).

Title: Insertion funnel for coffee machines for receiving eggs with simultaneous all-over exposure of the surface of the coffee grounds or liquid coffee extract to water
Inventor: ARCISZEWSKI BERNHARD
IPC: A47J31/06
Filed: 1988-01-19
Granted: 1989-02-23
Abstract: The invention relates to a coffee filter which as well as brewing coffee also prepares eggs at the same time, and also in the oblique position of the coffee machine ensures all-over water distribution and exposure of the surface of the coffee grounds to water, the brewing water supplied being guided and distributed without pressure by level and inclined sections of the base of the insertion funnel in such a way that, for hygienic reasons, it does not come into contact with the surface of the eggs. The brewing-water supply 1 passes through the guiding conduit 28 into the collecting bowl 8, which fills immediately. On further admission of brewing water, the water flows over level and inclined sections of the base 7 through outlet openings 15 distributed over the area onto the surface of the coffee grounds 18. The coffee grounds 18 are situated in a cylindrical cup filter 19 with flared flange 20 in a lower part 21 of the filter. The flavour-rich coffee 25 runs out of the outlet opening 24 into the coffee pot. The liberated superheated steam 32 from the volume chambers 33, 34 heats the inner funnel 27 of the insertion funnel 6 so intensely that the desired hardness of the eggs 26 is obtained by the existing energy. The brewing water 1 does not pass into the inner funnel 27. <IMAGE>

Title: Identifying and monitoring selected cylinders of IC engine - forming difference value between two RPM values of cylinders in ignition sequence
IPC: G01M15/11
Filed: 1992-03-13
Granted: 1993-05-06
Abstract: The method involves determining a mean r.p.m. value for a selective cylinder during a working stroke of each cylinder across a mean crankshaft angle of rotation range. A difference value is formed between the mean r.p.m. values of two successive cylinders in the ignition sequence. This difference value as an identification parameter is compared with a predetermined threshold value. The predetermined threshold value is established depending on the load and the r.p.m. of the IC engine. With the overstepping of the threshold value, a fault indication is activated. The difference value (D2) for the actual working cycle in addition to the difference value (D2') for the preceding working cycle of the same cylinder (Z2) is used as the identification parameter (EP). USE/ADVANTAGE - For selective cylinder identification and monitoring of combustion misfires in multi-cylinder IC engine. In addition, high combustion interruption rates can be reliably identified.
