Patent GB-948471-A (GB)
IPC: B65G59/02
Abstract: 948,471. Unstacking; reciprocating conveyers. MATHEWS CONVEYER CO. Ltd. Jan. 18, 1961 [Jan. 18, 1960], No. 2001/61. Headings B8A and B8C. Articles stacked on pallets are delivered from conveyers 42, 36 to a lifting platform 34 which is raised to a position at which the topmost articles in the stack are removed by an apron 44 reciprocated horizontally below the top layer of articles to deliver them on to a table 48, the platform 34 being raised stepwise to complete the unstacking. The various members of the apparatus are automatically controlled by electrical switch mechanism. Supplying loaded pallets.-The conveyer 42, which stores articles delivered, e.g. from a fork-lift truck, comprises a fixed inclined frame 60, Fig. 5, on which are mounted transverse rollers 64. A movable frame is mounted on the rollers 64 and itself carries rollers 86. The movable frame is reciprocated by an air motor 158 controlled by switches LS20, LS21, actuated alternately by a striker 166. Articles on pallets are urged along the rollers 86 until the leading pallet reaches projecting stops 153, 154. On lowering of the platform 34, a front section of the conveyer 42 is pivoted upwards about a shaft 98 by an air motor 122. The stops 153, 154 are carried on side members 146 pivoted at 152, and are normally in raised position due to the unbalance of the members 146 about the point 152. As the front section of the conveyer 42 is pivoted upwards, plates 156 welded to a member 114 raise the rear end of the members 146 thereby retracting the stops 153, 154 and discharging a loaded pallet on to the conveyer 36. Raising, unstacking and discharging.-The platform 34, Fig. 8, which is of H-shape, is lowered below the conveyer 36 and a discharge conveyer 38. A loaded pallet is delivered above the platform 34 against a stop 182 which automatically raises the platform. A pick-up roller 302, Fig. 12a, on the forward edge of the apron 44 is rotated to urge articles on to a plate 278 of the apron. An assembly 202 aligns the rear side of the stacked articles. A roller 204 forms a back stop towards which the apron 44 is reciprocated; and pusher 206 is both reciprocated and tilted as it urges a layer of articles from the stack towards the rear of the apron 44. As the apron is again advanced, articles on it are prevented by the next layer from being carried forward and are thereby transferred on to an accumulation table 48, and from there on to a gravity conveyer 54. The empty pallet is lowered with the platform 34 and discharged on the conveyer 38. Specifications 894,330, 894,353 and 948,472 are referred to.

Title: A mop bucket with a filter
Inventor: SINGLETON TERENCE
IPC: A47L13/58
Filed: 1998-03-30
Abstract: A mop bucket is divided into two main compartments 9,11 by a partition 4. Within compartment 11 is a filter compartment 10 containing a resilient filter 14. The filter compartment has an aperture 7 in a wall, which in the embodiment is common with the partition wall, this aperture communicating with the compartment 9. The upper end of the filter compartment is closed by a movable compression plate 5 which has apertures 7 for allowing entry of liquid from compartment 11. Mounted above the filter compartment on two guides is a mop wringing device 3. The arrangement is such that the container is filled in both compartments 9, 11 to below the top of the partition 4. The mop is wetted in compartment 11 and wrung out in device 3. By pressing down on device 3 the compression plate compresses the filter and cleaning solution is forced through the filter and into compartment 9 via the communicating aperture 7. Subsequent wringing of the mop causes dirt to be filtered out of the cleaning solution and thus there is always clean solution available in compartment 9 for mopping. The wringing device may be of the mechanical sort.

Title: Friction clutch with automatic wear compensation
Inventor: LAMPE JOERG
IPC: F16D13/75
Filed: 1998-04-21
Abstract: A friction clutch, for a motor vehicle, comprises a clearance provider 11, having an axial stop 13, and an actuating lever section 12 which is inherently elastic so that it exerts a resilient force on at least one relatively rotatable ring 15, 16 loaded by a spring (17, fig 3). The axial stop 13 is frictionally fitted in an opening 14 in a pressure plate 4 so that when friction linings 6 wear the axial stop 13 is moved and a pretensioning force exerted by the lever section is reduced. This reduced force allows the rings 15, 16 to move relative to each other, thereby increasing their axial length by rising on inclined surfaces (see fig 3). Increasing the rings 15, 16 axial length ensures that diaphragm spring 7 retains its original position as the linings 6 wear. In another embodiment (see fig 4) the axial stop 13 is constructed in one piece with the lever section 12.
