Title: Adjustable friction stay
Inventor: LANAWAY RONALD PHILIP
IPC: E05D15/30
Filed: 1994-05-27
Abstract: A window support in the form of a friction stay includes an open-topped track 10 to be fixed to a window frame, and a link arrangement for interconnecting the frame with the window sash. The link arrangement is pivotally mounted on sliders 20, 24 in the track 10, movement of the slider 24 being prevented during a substantial part of the movement of the friction stay. At one end, the track 10 is closed by a profiled cap 36, while at the other end the track 10 mounts an adjustable abutment 100, against which engages the slider 20 during closing of the window. When the window is closed, an angled end face 42 of a link enters the cap 32. In the event of inaccurate fitting or wear of the window seals, the window may be moved into closer engagement with the frame by adjustment of the abutment 100, whereby engagement with the slider 20 obliges the slider 24 to move towards the cap 32. This creates an additional pressure of the window against the window frame to improve sealing. A latching arrangement may be provided to initially limit the extent of opening of the window. <IMAGE>

Title: Biocidal hard surface treatment with sustained effect based on use of a copolymer of hydrophilic oxyethylene/oxypropylene and hydrophobic ester chain units
Inventor: DAVIS BRIAN
IPC: C11D3/48
Filed: 1995-08-18
Abstract: The invention provides a composition suitable for application to a hard or textile surface which comprises an aqueous solution, suspension or dispersion of a biocide and a copolymer comprising chain units A1 of the formula -OC n H 2n -where n is 2 or 3 and chain ester units A2 of the formula  where R is a hydrophobic group; where the mole ratio of units A1 to A2 is from 1:10 to 3000:1 and the copolymer has a molecular weight from 1000 to 100,000 and methods using a biocide and such a copolymer or using such compositions from controlling microorganisms. Such copolymers possess a hydrophobic part (A1) which will give some adherence to the surface (resisting removal on washing of the surface by water and weak surfactant solutions) and a hydrophilic part(A2) which will allow migration of the biocide through to the surface of the polymer, thus providing a sustained biocidal effect. The polymer is advantageously biodegradable by virtue of the ester linkage present in its backbone. The compositions may easily be removed from the surface to which they have been applied by the application of an alkali.

Patent GB-961656-A (GB)
Abstract: 961, 656. Parking time and like indicators. R. R. E. NILSSON. July 7, 1960 [July 7, 1959], No. 23276/59. Headings G4B and G4T. A parking or hiring period indicator for display in a vehicle window includes means set to indicate the starting time and intended duration of the parking or hiring period and means to prevent further operation of the indicator after the intended durations of a number of periods total to a predetermined amount. In one form a wheel 10 projecting through the case 1 is rotated until a number corresponding to the starting time appears in a window 4. During this setting a stop 27 on the wheel 10 contacts a stop 28 on a gear 25 which through intermediate gear 26 rotates a wheel 20 to bring a corresponding number on the wheel 20 to an aperture 5. A further wheel 30 projecting through the casing is then rotated causing further rotation of the wheel 20 and gear 25, 26 through a ratchet 31 until the time shown at the window 5 corresponds to the end of the period. This latter setting causes a disc 40 to be rotated through an angle corresponding to the duration of the period. Each time the indicator is reset the disc 40 is rotated by a further amount corresponding to each parking or hiring period until any after sixty hours when a projection 43 on the disc 40 hits a fixed stop 44 thus locking the wheel 30. The user then has to return the indicator to an authority where a seal is broken and the stop 44 removed while the disc 40 is turned back. The total number of available hours is shown at 7. A wheel 60 giving the date at a window 6 can be rotated when the wheel 10 is in the zero position. The vehicle number may be stamped on the case at 48. In a modification the numbers in the windows 4, 5 may be represented by a pair of clock hands (Fig. 5, not shown).
