Inventor: BAUER PHILIPPE
IPC: F02M3/06
Filed: 1989-02-03
Abstract: A valve, e.g. for use in a fuel feed device for an internal combustion engine for regulating carburetted airflow, comprises a housing (12) provided with inlet and outlet passages (24, 26) and a rotor (14) rotating between a first end position (Fig 2) where it connects the passages and a second end position as shown where it disconnects the passages, the rotor being biased towards the second position by a return coil spring (28) and being brought into the first position by an actuating winding when the latter is energized. The spring (28) is fixed to the rotor (14) and to the housing (12) and positioned so as to apply itself against at least one of the passages (24, 26) and at least partially close it in the second position. <IMAGE>

Title: Equipment for delivering a fluid
Inventor: ALI EREN
IPC: B05B9/08
Filed: 1989-05-05
Abstract: Equipment for delivering a fluid, such as herbicide, comprises a carrier in the form of a handset and a support tube 4, one end of which is removably connected to the carrier and the other end of which carries a distribution head. Within the support tube 4 a supply duct 6 conveys herbicide from the carrier to the distribution head, and electrical leads 8 provide a connection between the carrier, and the distribution head. The support tube 4 has a connector 10 which is releasably secured to the carrier by a screwthreaded sleeve 52. A spigot 18 of the connector 10 enters a bore in a valve of the carrier to provide sealed connection between the valve and the supply duct 6. First contacts 38 on the connector 10 engage second contacts 42 in the carrier to provide electrical connections. The support tube 4 can thus be coupled to the carrier 2 by a simple plug-in operation. <IMAGE>

Title: Transponder with code identification circuit having a surface acoustic wave device filter
Inventor: ARTHUR JOHN WILLINS
IPC: G01S13/75
Filed: 1989-11-14
Abstract: An identification circuit suitable for use as an identification tag for airport baggage includes a surface acoustic wave device 20 which functions as narrow bandwidth filter (eg. 10 kHz) for RF signals received at an antenna 10. A semiconductor integrated circuit 30 recognises an identification code which modulates the filtered signals and generates a reply code in response. The SAW device 20 provides substantial immunity of the circuit to RF interference. A coded RF signal is transmitted from antenna 10 by causing the reply code signal to modulate an RF resonance signal of the SAW device 20, which is either operated in an active mode being caused to oscillate at its resonant frequency, or for low power applications the device 20 may operate in a passive mode in which it acts as a filter to select harmonies of the reply code signal. <IMAGE>

Title: Setting-up comb for a flat knitting machine
Inventor: SHIMA MASAHIRO
IPC: D04B7/22
Filed: 1990-05-24
Abstract: A set-up comb to be disposed below the cap between needle beds in a V-bed flat knitting machine, comprises a comb bed (5) and a plurality of setting-up needles (4) mounted on the comb bed (5), each needle comprising a needle body (10) fixed to the comb bed (5) and a slider (11) slidably combined with the needle body (10). The needle body (10) has a hook- accommodating protrusion (20) for releasably receiving therein a hook (12) of the slider (11). When a double-stroke course of set-up yarn has been laid in zigzag pattern between the front and rear needle beds the set-up comb (4) is elevated to cause the hooks (12) of individual sliders (11) to hook the yarn at the crossing sites thereof, so that the set-up yarn can be lowered by the set-up comb (6) to a level below the needle gap. When the sliders (11) are then elevated, the hooks (12) retract into the hook accommodating protrusions (20) of corresponding needle bodies (10) and thus the set-up yarn is disengaged from the hooks. <IMAGE>

Title: Pedestal crane.
Inventor: MORROW WILLIAM DOUGLAS
IPC: B66C23/84
Filed: 1991-06-17
Abstract: A crane design which permits limited tilting/rotation in the plane of loading of the upperworks of a pedestal crane independently of the central support (K) thereof, and independently of the thrust and radial bearings (37, 36) about an extension of such central support. Means for centering the vertical loading vector and horizontal overturning moments by restricting the possible displacements thereof are disclosed, as are methods for accomplishing the same. Arcuate surfaces (38, 39) attached to the pedestal (K) and upperworks permit limited tilting to confine the point of action of the applied load towards the centre line. The radial bearings can also be similarly angled. <IMAGE>
Patent GB-2257272-A (GB)
Title: D.c.level generator
Inventor: PYE RICHARD
IPC: G05F1/46
Filed: 1991-06-29
Abstract: A method and apparatus for sequentially refreshing each of an array of sample and hold output circuits 2 in a DC level generator. Each sample and hold circuit makes a selected DC voltage available. For each of the sample and hold output circuits in turn, the voltage which it is desired to store in that circuit is generated by a voltage level source. The generated voltage is compared via amplifier 6 with the voltage stored by that one sample and hold output circuit 2 to produce a voltage difference signal and an error correction storage and hold circuit 10 is charged to a voltage proportional to the voltage difference signal. Charge proportional to the voltage stored in the error correction storage and hold circuit 10 is then transferred to the selected one sample and hold output circuit 2 to reduce the difference between the compared voltages. Thus a large number of sample and hold circuits can be refreshed by a single DC level generator. The sample and hold output circuits may also be paired up and by using two error correction storage and hold circuits switched so that when one capacitor 10 is being charged proportional to the error signal from one output 2 the other capacitor 10 can be passing the previously stored charge to the second output of the pair (see fig. 3). <IMAGE>

Title: Ribbon lifter for multicolour printer
Inventor: SUZUKI MASATO
IPC: B41J19/20
Filed: 1992-06-29
Abstract: A selective printer of the kind having a reciprocable printhead carriage and having provision for shifting an ink ribbon between two positions of use, whereby to enable printing to be done in two different colours, is characterised in that:.   (a) the provision includes a ribbon-lifter pinion having two mutually phase shifted axially separated sets of pinion gears, said pinion being axially moveable in response to being abutted by said printhead at one end of the range of movement thereof. (b) the pinion is driven by a driving gear which is normally in register with one of said sets of pinion gears, but which interdigitates between said pinion gears when the pinion is to be driven, said driving gear having a continuous untoothed peripheral portion and teeth axially indented into each face in the peripheral region, said teeth being phase displaced by the same amount as those of the pinion. (c) said arrangement being such that when the pinion is in said register with one of the sets of pin ion gears, said pinion gears engage said continuous peripheral portion to rotationally immobilise the pinion; and when said driving gear is interdigitated, the respective sets of gears on the pinion engage the indented facial gears in alternation.   As shown (Fig 8) the pinion (9) is rotatable and axially slidable on the printhead-carriage supporting shaft (4) against a spring (8). In the normal state (as shown) the tips of the teeth (9a) of one gearset ride on the periphery (10c) of the drivewheel (10). When the carriage is traversed to the right, the collar (4a) urges the pinion (9) until the teeth (9b) engage teeth (10b) of the driving gear (10) and the teeth (9a) engage teeth (10d). The wheel 10 has only the number of teeth shown, and, when engaged, allow the pin ion to be driven to the next stable position of disengagement. It is stated that this arrangement prevents accidental misengagement during a power failure. <IMAGE>
