  • Patent number: 11951065
    Abstract: An apparatus for generating a rotary reciprocating motion comprises an input shaft which is driven with unidirectional rotation and an output shaft for delivering reciprocating rotary motion. A first magnetic or ferromagnetic ring is disposed about a rotation axis fixed to the input shaft and a second magnetic or ferromagnetic ring is disposed about the rotation axis fixed to the output shaft. At least one is formed as an arrangement of permanent magnets. The first and second rings are disposed one within the other around the rotation axis. The magnetic coupling between the rings in combination with the effect of an output load results in the desired reciprocating motion of the output shaft.

  • Patent number: 9723945
    Abstract: In a device (1) for making a beverage on the basis of interaction between a beverage extract and an extracting fluid, which comprises an openable and closeable chamber (50) for receiving and accommodating a quantity of the beverage extract, and heating/cooling means (30) for setting the temperature of the extracting fluid, arranged upstream of the chamber (50), a beverage making process can be performed with extracting fluid that is exactly at a desired temperature. During heat-up or cool-down phases of the heating/cooling means (30), the extracting fluid is transported to another position than the chamber (50) where the beverage making process is supposed to take place. For the purpose of determining an appropriate path of the extracting fluid in every possible situation, valve means (60) are applied, which are switchable under the influence of a change of the flow rate of the extracting fluid.

  • Publication number: 20170071245
    Abstract: Citrus fruit pressing devices, apparatus and methods are disclosed. Several features that can reduce the incidence of rupturing oil pockets in the fruit peel can be employed to improve the taste of the juice pressed from the fruit. One feature includes cutting (307) the peel at least partly along a circumference of the fruit to reduce rupturing of oil pockets when the fruit is flattened and the surface of the fruit is folded over. Another feature includes utilizing a curved knife, which can provide a relatively deep cut and a smooth expansion of the peel. According to other aspects, juice extraction can be improved by employing one or more protrusions in a surface of the pressing element to press areas of the fruit in which the peel of the fruit is not present. Another aspect is directed to using the pressing speed to control the pulp content of the juice.

  • Patent number: 9357869
    Abstract: The present invention relates to a masticating separator for separating fruit or vegetable juice from fruit or vegetable pulp. The masticating separator comprises a housing (21), an inner wall (43) in the housing (21), an auger (22,71) rotatably mounted in the housing (21), a cavity (46) defined between an outer surface (39,86) of the auger (22,71) and the inner wall (43) to receive pulp and juice, and a juice passageway (44) separated from the cavity (46). An elongate aperture (52) is formed in the inner wall (43) extending between the cavity (46) and the juice passageway (44). Therefore, when the auger (22,71) is rotated about its longitudinal axis to urge pulp and juice along the cavity (46), juice in the cavity (46) is urged to flow through the aperture (52) to the juice passageway (44).

  • Publication number: 20140332520
    Abstract: A baby bottle warmer is disclosed, comprising a chamber (3) for receiving a baby bottle comprising a base (5) and side walls (6), configured so that in use the sides and base of the chamber (3) are at an angle to the surface on which the baby bottle warmer is supported. A water reservoir (11), positioned higher up than the chamber (3), feeds water into the chamber (3), by gravity, through a pipe (12). The reservoir (11) is sealed except for the pipe (12) so air may flow in the opposite direction to the water along the pipe (12) until the water level in the chamber (3) reaches the level of the outlet (15) of the pipe (12) at which point the water level is prevented from rising. When the baby bottle is inserted into the chamber (3), the water is displaced so that it forms a layer between the baby bottle and the walls (5, 6) of the chamber (3). This layer of water acts as an efficient heat transfer mechanism.
