Patent CH-558483-A (CH)
Title: Rotating shaft coupling in oil pumps etc - has number of balls including one of larger dia.
IPC: F16D3/06
Filed: 1972-10-09
Abstract: This coupling is used for connecting two rotating shafts. The end of one shaft has a smaller diameter than the other one and it fits into the bore of the larger diameter shaft. The smaller diameter shaft 4 is concentric with the other shafts. The smaller shaft has a flat on its end. The outer shaft 9 has radial bores through which the balls are fitted into the assembly. These balls are held between the smaller shaft and the locking ring 20 which is held in a groove on the outer circumference of the hollow shaft. The coupling is achieved by the keying effect of the larger diameter ball 17 which contacts the flat or the smaller diameter shaft. Axial movements are readily accommodated by this coupling. This coupling can also act to a small extent as a universal joint if clearances are arranged accordingly.

Title: Folding picnic table
Inventor: WU CHING KUN
IPC: A47B3/02
Filed: 2000-03-30
Abstract: A folding picnic table has a foldable slatted top 21 and a folding support structure. The support structure comprises a pair of elongate parallel support bars 10. To each end of these are pivotally attached via a pair of 'L' shaped brackets 12, two leg assemblies. Each leg assembly comprises a main leg 14 and a further subdivided leg having a lower part 17 and an upper part connected together by an 'N' shaped plate 15 such that the axes of the two parts are not aligned. The main leg passes through the gap between the two parts and is pivotally attached to the 'N' shaped plate to form and 'X' leg arrangement, the top end to each leg of the 'X' being attached to an end of each of the bars 10 via the 'L' shaped plate 12. In use the 'X' can be folded together and then the resultant folded legs folded to lie parallel with the bars 10. It can be seen that when erected the inner ends of the split leg act as a stop for the full leg. The table top comprises plurality of slats 21 joined below via flexible members 22, and having transverse members 24 which are dimensioned to fit exactly between the bars 10 in the open position. Preferably the ends of the bars 10 have spigots 11 which fit into holes in the terminal slats of the table top when folded overs.

Title: An absorption chiller
Inventor: TUCKER ROBERT JAMES
IPC: F25B33/00
Filed: 2000-05-08
Abstract: An absorption chiller wherein refrigerant such as water is dissolved in liquid absorbent such as lithium bromide to form a solution of refrigerant in the absorbent. The absorption chiller includes a generator 4 to boil-off the water refrigerant from the lithium bromide absorbent to separate the water as stream from the lithium bromide. The generator 4 comprises an upper tank 42 and a lower tank 36 interconnected by plain heat exchange tubes 38A and finned heat exchange tubes 38B. Two thermo-syphon tubes 58A and 58B also interconnect and open into each of the tanks containing the aforesaid solution which flows from the upper tank 42 through the tubes 58A, 58B to the lower tank 36 and from the lower tank to the upper tank through the heat exchange tubes 38A, 38B wherein aforesaid boil-off takes place. The heat exchange tubes are disposed in cross-flow relation to hot heating gases or products of combustion flowing in direction X through a combustion chamber 46, from a fuel gas pre-mix package burner 50, the heat exchange tubes being in said combustion chamber. Heat insulation material separates the thermo-syphon tubes from the combustion chamber. Steam leaves the upper tank through an outlet 72 and concentrated lithium bromide through an outlet 70. The weak solution of lithium bromide is introduced into the upper tank through an inlet opposite the upper end of thermo-syphon tube 58A.

Title: Initialisation of cameras
Inventor: DORON AMIR
IPC: H04N1/21
Filed: 2000-07-19
Abstract: The control circuit (30) in a digital still camera (10) executes a full initialization procedure when an ON/OFF pushbutton control switch (62) is first actuated to an ON condition to thereafter permit image information to be obtained via an image sensor (18) and a processing circuit (22, 24, 26, 28, 36) for storage in a memory (38, 44). The control circuit (30) thereafter executes a reduced power consumption sleep mode when the ON/OFF pushbutton control switch (62) is next actuated to an OFF condition. The control circuit (30) thereafter executes an abbreviated initialization procedure when the ON/OFF pushbutton control switch (62) is next actuated to the ON condition. This ensures that the user will not miss as many photo opportunities as would otherwise occur if the camera (10) had to go through a lengthy full initialization procedure of approximately ten seconds each time the camera (10) is turned ON. In order to conserve battery power (31), the reduced power consumption sleep mode is terminated if the ON/OFF pushbutton control switch (62) has not been actuated within a predetermined interval, e.g. two hours, since its last actuation. The sleep mode is "hidden" to the user in the sense that the camera (10) displays and LEDs are not illuminated and the control circuit (30) will not respond to the actuation of any of the manual pushbutton control switches (64, 66a, 66b, 68, 70a, 70b) except for the ON/OFF pushbutton control switch (62).

Title: Indicating a preferred network to a multimode terminal using a paging signal
Inventor: LAIHO KEIJO TAPIO
IPC: H04W36/14
Filed: 2001-01-10
Abstract: In order that a multimode mobile communication terminal may receive a message ( <I>e.g.</I> a fax) which can be transmitted over only certain networks, a paging message includes data specifying a preferred network. In this way rejection of the call if the terminal is not currently operating on the preferred network is avoided. Also claimed are methods for determining from a paging response from the mobile terminal whether the terminal is currently operating on a preferred network and if necessary establishing a new connexion over a second network, and a method of inhibiting handoff to a second network if the second network cannot support the call.

Title: Sleeve for receiving a tray
Inventor: BRAIN MICHAEL
IPC: B65D77/04
Filed: 2001-02-06
Abstract: A sleeve is constructed from a cut and creased sheet material blank having a plurality of panels (4, 10, 14, 18, 22, 26) therein defined between crease lines. The sleeve is formed by adhering a first panel (4) defined between a free edge (6) and a first crease line (8) to a last panel (26) defined between the opposite free edge (28) and a last crease line (24) to define the sleeve construction with a pair of open ends through either of which a tray can be inserted. The first panel (4) is adhered underneath the last panel (26) well behind the free edge of the last panel (26) so that the first crease line (8) is concealed behind the last panel (26) when the sleeve is erected. Remaining crease lines define the vertices of the sleeve and provide its characteristic shape. The free edge (28) may have an arcuate or other non-straight profile. The crease lines are arranged to allow the sleeve to be folded flat.

Title: Metadata generation
Inventor: BIRD COLIN LEONARD
IPC: G06F17/30
Filed: 2001-06-29
Abstract: Source texts (500) are processed to extract primary metadata in the form of a plurality of sets of words (504, 505). Each of the source texts (500) is compared with each of the sets of words (504, 505). A clustering program extracts the sets of words (504, 505) from the source texts (500). Latent Semantic Analysis is used to compare the similarity of meaning of each source text (500) with each set of words (504, 505) obtained by the clustering program. The comparison obtains a measure of the extent to which each source text (500) is representative of a set of words (504, 505).

IPC: B41J2/165
Filed: 2002-01-30
Abstract: A printer 1 comprising one or more printing elements 10a-d is arranged to print upon sheet 8 as it passes along transport path 6. After printing is complete the sheet is conveyed to a sheet diverter 12, whereupon the media is either transferred to a conventional output tray 14, or alternatively to an optical scanner 16 if a user had previously selected a test pattern to be printed upon that particular sheet. Whilst normal printing to output tray 14 resumes, the scanner performs an optical check of the test pattern to determine whether all inkjet nozzles are functioning, before transferring the sheet to alternative output tray 18. If an error is detected, printhead servicing is carried out to restore the printhead to normal function.
