Abstract: 1367189 Vehicle washing apparatus G T ENNIS 1 Sept 1972 [7 Sept 1971 10 Aug 1972] 40561/72 Heading B7J  A vehicle washing apparatus has a fixed support frame 13 and a brush assembly, e.g. 11 comprising a first arm 20 pivotally mounted at one end to the frame 13 at a point 22 laterally outside the predetermined path 14 of a vehicle to be washed, a second arm 30 pivotally connected adjacent one of its ends to the other end of the first arm 20, rotatable brush means 32 mounted at the end of arm 30 remote from the interconnection of arms 20 and 30, a first tension means such as a spring 40 connected between frame 13 and arm 20 so as to urge arm 20 towards a position generally parallel to path 14 and a second tension means such as a spring 46 connected between arm 20 and the end of arm 30 remote from brush means 32 so as to urge arm 30 towards a position generally transverse to path 14. The tension springs 40 and 46 are attached to arm 20 at brackets 41 and 47 each having a series of holes to any of which the respective spring may be hooked to obtain various values of spring tension. A compression spring means 50 carried by arm 20 is engageable with abutment means 52 carried by arm 30 so as to limit the relative movement between arms 20 and 30. The movement of arm 20 is partially controlled by a spring damper 42 connected between arm 20 and frame 13, and a further damping cylinder 55 is connected between arms 20 and 30. A piston-rod (59), Fig. 4 (not shown), of cylinder 55 is connected to arm 30 via a curved slot (58) in a plate (57) secured to arm 30 and acts as a lost motion linkage to allow a certain relative movement between arms 20 and 30 before damping occurs. A pair of brush assemblies 12 and 11 may be provided on opposite sides of path 14 with their brush means 32 overlapping in the absence of a vehicle, as shown in Fig. 1. The or each brush means 32 moves across the front, along the side and across the back of a vehicle being washed. In an alternative embodiment, Fig. 10, the second arm 130 of the brush assembly comprises telescopic outer and inner portions 132 and 133 connected to first arm 120 and brush shaft 141 respectively. Antifriction means to facilitate the telescopic movement are formed by rollers 134 and 135 carried by portion 133 to engage the interior of portion 132. Shaft 136 of roller 134 extends through slots 137 in each side of outer portion 132, and carries tension springs 138 connected to the portion 132 at 139 so as to urge the inner portion 133 telescopically outwardly of portion 132.

Abstract: 1,269,840. Ground-effect device. NATIONAL AERONAUTICS & SPACE ADMINISTRATION. 14 Aug., 1969 [15 Aug., 1968], No. 40578/69. Heading B7K. A ground-effect device comprises a continuous sidewall 23 and a dished upper wall 25 having a central portion 29 for supporting a load and a portion extending upwards from the central portion to the sidowalls, the walls defining a plenum chamber 27 to which pressurized air may be admitted through one or more inlets 31. The upwardly-extending wall may be frustoconical and the central portion 29, which may be closely adjacent to the plane of the bottom of the plenum chamber, planar. When the device tilts the resulting increased pressure at the depressed side and the increased escape of air at the raised side cause a restoring torque. A plurality of such devices may support a mobile platform (11), Fig. 1 (not shown), used to simulate movements in space.

Abstract: 840,306. A.C. generators. GENERAL MOTORS CORPORATION. Dec. 23,1958 [Dec. 26, 1957], No. 41459/58. Class 35. [Also in Group XXXVI] In an A.C. generator feeding a D.C. load through rectifiers for motor vehicles, the rectifiers are mounted in heat-transfer relationship with the alternator end cover. In an air-cooled form shown in Figs. 1 and 2, in which the alternator may be of any type but as shown is of single or polyphase type with a rotating field member energized through slip-rings 36, 38, and brushes 40, the rectifiers are arranged as plugs 48, 84 in holes in radial webs in the end cover 18. These rectifiers are of conventional silicon junction type (see Group XXXVI) and the threaded casing parts and insulated terminals 54, 104 provide the two terminals of the rectifiers. In the three-phase form shown, three rectifiers 48 are secured in webs 66 in the end cover, these webs having heat-dissipating fins 70. An insulated sub-frame 72, similarly provided with webs 82 having fins 83 carries a further three rectifier plugs 84 of opposite polarity to plugs 48. The sub-frame 72 is connected to the D.C. output terminal 76 and the end cover 18 provides the earth terminal, the stator windings 22 of the alternator being connected to the insulated rectifier terminals 54, 104 to provide a three-phase, full-wave bridge. The end cover 18 is thermally insulated from the stator by a spacer 19. In an oil-cooled modification, Fig. 6, the rotor has interdigitated poles 112, 114 alternately polarized by a fixed field coil 130. The rectifier plugs 132, 134 are embedded in the end cover 89, plugs 134 being threaded directly into the earthed end cover, while plugs 132 are insulated from it by insulation 142. Metal strips 144 provide cooling fins and also terminal lugs for the rectifiers 132. The rectifiers are connected in a three-phase bridge as before. Cooling oil from a pump 170 and cooler 171 is fed into rectifier cooling chamber 156 at pipe 160 connected by an arcuate duct 161 to the bottom of the chamber 156. Back-syphoning is prevented by a bleed hole 161a. Oil also passes by ducts 162, 164, 165 to the air-gap 166 to cool the alternator parts, and by a duct 174 to lubricate rotor bearing surfaces 123, 124 before draining at 173 to sump 172. This sump may be the flywheel or transmission housing of the motor vehicle. Instead of being screwed into the end cover, the rectifier plugs may be pressfitted into suitable bores, or the rectifier elements may be secured directly into recesses in the end cover by turning the edges over so as to secure an insulated terminal portion.

Filed: 1958-12-30
Abstract: 873,411. Lubricators. FISHER, J. W. March 23, 1960 [Dec. 30, 1958], No. 41975/58. Class 12 (3). A device for the pre-starting lubrication of an internal-combustion engine comprises a reservoir in which oil is stored under pressure, handcontrolled means for causing the automatic discharge of oil from the reservoir to the engine bearings and means operating simultaneously with such discharge to deliver a supply of upper cylinder lubricant to the engine inlet manifold. The reservoir 1 is initially charged with oil from the galleries through the connection 30 and spring-loaded valve 25, being held under pressure by the spring-loaded piston 11 whose top, a charged position is visually indicated by means of an electrical contact 39. Before starting the engine for normal running a piston member 21 is pulled by a control cable 17, causing a cam surface 23 to open the valve 25 and oil in the reservoir to be forced by the piston through the connection 30 to the oil pressure gallery of the engine. Simultaneously, upper cylinder lubricant is drawn from a reservoir through a non-return valve 34. When the piston 11 reaches its lower, or discharged, position, a visual indication is given by means of an electrical contact 38 and the control cable is released. The member 21 returns under pressure of the spring 20 and the upper cylinder lubricant is discharged to the inlet manifold through the non-return valve 35.

A method of forming fibre-containing polymeric sheet material capable of being thermoformed or cold pressed includes the steps of forming a paste by mixing a natural or syn thetic polymeric particulate solid with a binder, preparing a fibrous pulp, preparing a furnish by mixing the paste with the pulp in a ratio by wt. of solids from 25% paste to 75% fibre to 75% paste to 25% fibre, draining the furnish on a foraminous screen, and drying. The particulate solid may be acrylonitrile butadiene styrene, polyethylene, or a mixture thereof, or an epoxy or phenol formaldehyde resin, or mixture thereof. The binder may be a natural or synthetic polymer e.g. styrene-butadiene, acrylonitrile butadiene styrene, urea or melamine formaldehyde resin, guar gum, starch, or pectin. The fibres may be of wood, cotton, asbestos, polyamide, polyester, carbon, glass, rayon, metal, or mixtures thereof. A precipitant e.g. alum, or chrysotile asbestos may be mixed with the fibrous pulp. Conventional additives e.g. antioxidants, plasticizers, fillers, surface-active agents may be used in the preparation of the paste. The surface active agent may be an ethoxylated alkyl phenol. The drained and dried sheet material may be stabilised as it leaves the paper-making machine by being subjected to heat and pressure to form a surface skin. This may be done by a hot rolling process or in a laminating press.
