Title: Dressing grinding wheels
Inventor: MIDGLEY CLIVE JOHN SIMMONS
IPC: B24B49/18
Filed: 1987-03-10
Abstract: The instant at which a truing and conditioning roller (20) first touches a grinding wheel (10) to be dressed is detected by sight relative angular displacement between discs (38, 40) coupled respectively to a motor (34) and the truing wheel (20). The driving disc (38) rotates the driven disc (40) via a last motion connection comprising a pin (42) and a slot (44). As soon as the slowly rotating truing wheel (20) touches the quickly rotating grinding wheel (10) the truing wheel (20) is accelerated to transfer the pin (42) from one end of the slot to the other. The relative angular displacement between the discs (38, 40) can be sensed optically by arrays of holes (47, 50) in the discs, the holes being in registry when the pin is at one end of the slot and out of registry when the pin is at the other end of the slot. <IMAGE>

IPC: B65D81/32
Filed: 1987-05-14
Abstract: A pull-open can comprises two compartments (14,15) which each have a pull-open means. The can is formed as a cylindrical body (10) with end plates (11,12) and is axially divided into two sections (14,15) by a partition wall (13) tightly installed within the cylindrical body (10). A pull-open means can be installed on the partition wall (13) and may be the only pull open means for the compartment (15), the pull open means having a hook-like ended grip (18) extending to a position near an annular seal plate (171) of the pull-open means (17) on the upper end plate (11), so that the grip (18) can be pulled by using the annular seal plate (171) after it has been pulled from the end plate (11). The partition wall (13) is pulled away from its original position and the contents of the compartments can mix. The can can preserve two different drinks, serve the drinks separately (if the lower compartment has its pull- open means in the end wall 12), or even serve a mixed drink by combining the separately preserved contents held in the two compartments. Rim projections formed around the upper and lower end plates may be screw shaped for axially connecting cans together. <IMAGE>
Patent GB-2207790-A (GB)
Title: Data-carrying devices
Inventor: GLASSPOOL ANDREW JIM KELLEY
IPC: B42D15/10
Filed: 1987-08-04
Abstract: A data carrying device (2) communicates in a contactless manner with an interrogator, which transmits data by amplitude modulation of a carrier (Fig. 4c). The device includes a data detection circuit (10) which is synchronized to the carrier and which generates a pulse (T1) of a first length at regular intervals if the carrier remains unmodulated and generates a pulse (T2) of a different length if a modulation of the carrier is detected. An input/output line (16) conveys the pulses to a processor (6). During data transmissions from the interrogator, pulses of both lengths, representing the data, are delivered to the processor. During data transmissions from the device (Fig. 3), pulses (104) of one length act as clock pulses determining the time at which data is applied to the input/output line by the processor. The impedance of the token is modulated, and the carrier thus affected in a detectable fashion, in response to the data placed on the input/output line by the processor.

Title: Data reduction of digitised speech signals
Inventor: SEVERWRIGHT ROBERT ANTHONY
IPC: H04B1/66
Filed: 1989-03-15
Abstract: Speech signals, e.g. between a telephone 1 and telephone 9, are digitised in circuit 2 and reconverted in circuit 8. Successive blocks of digitised data, e.g. 16m seconds thereof, are compared with each other in the frequency domain in comparator 14, the conversion having been effected in block 13. If one block is similar to its predecessor wrihin pre-set limits, that block is not sent to the output 5, e.g. because 15 is opened and instead a control signal 14b is passed to the communication link to instruct a store 19 to repeat the previous block at the other end of the communication link. Thus only critical data blocks are transmitted and the data rate is reduced. This can be used for communication with an aircraft. <IMAGE>

Title: Drivers station of a construction machine with control lever movable to an out-of-the-way position
Inventor: KOBAYASHI MASAHIKO
IPC: E02F9/20
Filed: 1989-09-29
Abstract: The lever mount (11), eg for an implement control lever (9, 10), is tiltable between an approximately upright rest position and a tilted operational position which partially blocks the passage (R) provided in front of the driver's seat. The lever mount (11) is normally biased toward the rest position by a biasing element (16). Thus the upright rest position facilitates the driver's access. A bidirectionally operable locking mechanism (50) is provided for the lever mount (11) for reliably holding the lever mount (11) in position at its tilted position. The locking action of the mechanism (50) is effective not only in the rising direction of the lever mount (11) but in its tilting direction. The mechanism action in the former direction resists an over-tilting movement of the lever mount (11) beyond its permissive operation range, thereby protecting the mount (11) from damage. <IMAGE>
