Abstract: ABSTRACT         A device and method for forming a pyrolytic coating A device is described for the formation, by pyrolysis, of a coating of metal or metal compound on one face of a moving hot glass substrate (16) by bringing the face into contact with a gaseous reagent. The device comprises support means (20) for conveying the substrate (16) through a coating chamber (14), an ejection nozzle (10) for supplying and distributing reagent gas to the coating chamber (14) and means for discharging exhaust gas from the coating chamber (14). The ejection nozzle (10) has a slot (12) which extends transverse to the path of the substrate (16). The slot (12) opens directly into the coating chamber (14). The longitudinal internal walls (24) of the slot are substantially parallel to each other. The length of the slot (12) is at least equal to the width of the substrate (16) to be coated. The internal walls of the ejection nozzle (10) define a continuous convergent path, to cause the flow of reagent gas to conform to the dimension of the opening of the slot 12, the angle of convergence (a) of the convergent path not exceeding 14° at any point.

IPC: B62H1/12
Filed: 1992-08-07
Abstract: A stabiliser system, primarily for supporting a pedal bicycle and its rider upright at the halt, comprises a spring-loaded telescopic arm (26) which is connected at its upper end by a pivot (21) adjacent the rear wheel spindle (12) to a bracket secured to the spindle (12). A bolt (31) pivoted to the bracket engages the gusset plate (13) to resist clockwise motion of the bracket and a gas strut (28) extends between the bracket and the arm (26). At the lower end of the arm (26) is a cross-shaft (33) carrying stabiliser wheels (34, 35). The arm can be lowered by a cable (46) to move a roller (36) on the cross-shaft beneath the tyre of the wheel (11) so that a large part of the weight of the rider is transferred to the ground through the rear wheel (11), the roller (36), the cross-shaft (33) and the stabiliser wheels (34, 35). The cable (46) is in the form of a closed loop and passes around a guide (41) on the cross-shaft, around tapered guide pulleys (77) carried by a dependent bracket (62) within which is pivoted an arm (53) carrying a shaft (56) on which there is a tyre-engaging wheel (57) and two spools (58). The bracket (62) contains a cam (67) which can be operated from the handlebars via a Bowden cable (75). To lower the arm (26), the wheel (57) is moved by the cam into engagement with the tyre of the bicycle wheel (11) to rotate the spools (58) and draw in the cable (46).

Patent CA-2119468-A1 (CA)
Title: Skin cleanser
Inventor: GANGADHARAN BALGOPAL
IPC: A61Q19/00
Filed: 1992-09-11
Abstract: This invention covers a composition for forming an applique for cleaning or treating skin comprising a lower alcohol or alcohol/water solvent in which is dissolved between 0.1 to 20 % by weight/volume of a polymer consisting essentially of a non-acrylate pre-polymerized high molecular weight, dermatologically acceptable, adhesive polymer. The cleansing is accomplished by applying the formulation to skin as an applique, drying the applique, contacting the dried applique with an adhesive tape type material which bonds with the applique, and then pulling the applique/tape away from the skin. These skin cleansers are based on certain naturally occurring and synthetic polymers which are soluble in simple alcohols, or simple alcohol and water mixtures. It has been found that the selected polymers remove surface and follicular debris when formulated and applied without additives which modify their native configuration. Adding polymerizing agents or cross-linkers to the selected polymers reduces the capacity of these appliques to effectively remove soil. Thus polymers are pre-formed, that is they are not presented as monomers and cross-linked when applied to the skin.

Title: Rotary forging apparatus
Inventor: INATANI SHUJIRO
IPC: B21H1/04
Filed: 1994-11-08
Abstract: A rotary forging apparatus has a first rotary ram a second rotary ram     facing together in a vertical direction and a shaping roller equipped beside the rams. The apparatus forges a product from a material work    by sandwiching the work (10) between the first ram     and the second ram     pressing the work     by the rams, thinning the work      into the disc part of a product, pressing the excluded material out of the rams by the shaping roller to the sides of the rams and shaping the rim part. When the apparatus forges a wheel having a V-grooved or U-grooved rim part      scars or voids are often generated on the rim part, since the roller does not move in the vertical direction in prior apparatuses. This invention provides the shaping roller with a supporting device, a vertical transference device and a horizontal transference device. The roller is moved also in the vertical direction, accompanying the thinning of the work.     Vertical movement enables the roller to divide the extruded material in a suitable ratio into two parts. The rim part is immune from scars or voids because of the vertical transference of the roller accompanying the thinning of the work.
