Title: Dispenser for disposable sheet supplied in roll form
Inventor: CRISP DAVID JOHN
IPC: A47K10/38
Filed: 1991-06-11
Abstract: The dispenser, e.g. dispensing toilet paper, has rotatable support 211 carrying roll supports 211, 212, 231, 232, paper being dispensed from the roll on the lowest support. Each roll has a gravity-pivoted, residue-sensing lever 214 which rests on the roll and co-acts with adjustable stop 217 to hold support 211 still. When the dispensing roll reaches a minimum residue of paper, lever 214 is released from stop 217, and support 211 has a gravity-induced, anti-clockwise rotation until the next full roll is in the dispense position. Gravity-pivoted lever 216 co-acts with four ratchet teeth 233 to prevent clockwise rotation of support 211. Two other embodiments (Figs, 1 to 4) support two rolls, with similarly automatic roll advance. <IMAGE>

Title: Method and apparatus for feeding articles.
Inventor: LEATON TIMOTHY HOWARD
IPC: B65G47/84
Filed: 1991-07-11
Abstract: A feeding apparatus comprising an upper movable carrier (1) comprising a plurality of guides (7), such as, for example, receptacles, which are transported at a predetermined speed and with a predetermined spacing along a predetermined path. The guides each have an open bottom and are each adapted to receive articles which are individually fed thereto. Over a first portion of its path, each guide (7) lies immediately above a lower carrier (11) which closes the bottom of and moves in synchronism with the said guide (7), so as to allow one of the said articles to become held within the said guide (7) by the said lower carrier (11) for a sufficient period of time as to allow the said article to settle. Over a subsequent portion of the path, the guide (7) and the lower carrier (11) are separated from one another, thereby exposing the article on the lower carrier with accurately defined position and timing. The invention sets out to provide feeding apparatus capable of presenting articles in accurately defined sequence at a relatively high rate and with a sample and cheap construction.

Filed: 1992-06-26
Abstract: The device comprises an outer tube (25) having a flared or funnel portion (27) at one end thereof and an inner tube (26) held concentrically within the outer tube. A float (35) having a collar (32) which slides up and down the inner tube (26) is located within the inner tube (26) and has an indicator (31) connected thereto by webs (37). A scale (38) is marked along the outside of the non-flared portion of the outer tube (25). To use the apparatus, it is inserted into a cell in the battery through one of the filling holes therein until the lower end of the inner tube (26) rests against the top of the battery plates. If the indicator (31) shows the electrolyte level to be too low, distilled water can be poured into the funnel (27) on the outer tube (25) which directs the water into the battery via the space (43) between the outer and inner tubes (25, 26). As the water is added, the level of the electrolyte and the indicator (31) rise.

Title: Suspension systems
Inventor: RANDLE STEVEN JAMES
IPC: B62D21/11
Filed: 1993-09-14
Abstract: A suspension system for a car comprises two wishbones (12) each connecting the hub of a car wheel (10) to a sub-frame (14). Each wishbone is pivotally mounted on the sub-frame (14) but is not compliant so that no compliant movement occurs between the wishbone (12) and the sub-frame (14). The compliance of the suspension system derives from four compliant members which connect the sub-frame (14) to a monocoque. The compliant members each comprise a generally hollow cylindrical elastomeric bush which is stiff radially thereof, but soft axially thereof. The axes of maximum stiffness of the bushes intercept one another to define a shear centre of the arrangement which lies on the ground. Furthermore, the four bushes are arranged on the sub-frame (14) such that their radial axes of stiffness intercept one another on a lateral axis A which joins the contact patches of the two wheels (10). <IMAGE>
