Title: Improvements in and relating to fluid-flow meters and the like
IPC: G01F1/20
Filed: 1934-11-24
Abstract: 447,895. Flow meters. STOKOE, C. L., 11, King Edward's Road, Newcastle-on-Tyne. Nov. 24, 1934, Nos. 8174/36 and 8175/36 (both divided out of 447,809). [Class 69 (i)] Fluid-flow meters in which the action of the fluid against a movable member turns a spindle are provided with means to operate alarm and/or control gear at a predetermined flow, said means embodying a visible indicator and being adjustable to vary the value of the predetermined flow. The spindle a, Figs. 1 and 3, carries a pointer b movable over a dial c, and the alarm &c. gear is operated by a tappet d on a disc e. The disc e is normally pressed against the pointer boss b<1> by a washer f and spring g<1> so as to turn with the pointer, but may be adjusted after loosening a nut g to slacken the spring. Its setting is indicated by a scale e<1> and a line f<1>. In the form shown, the tappet tilts a pivoted conducting member h to cause a contact h<1> to engage and raise a contact j<2> on a pivoted conducting member j to close a circuit through terminals 1, 2 and open a circuit through terminals 2, 3. In another form, the tappet engages a spring- pressed lever and causes the operation of a valve so that compressed air blows a whistle or operates control gear.

Title: Forming a sputtered polymeric coating
IPC: C08F2/52
Filed: 1976-03-02
Abstract: 1495480 Forming a sputtered polymer coating AIRCO Inc 2 March 1976 [3 March 1975]  08294/76 Heading C7F A polymer is deposited on a substrate by simultaneous glow discharge polymerization and sputtering by establishing a glow discharge in a vacuum chamber containing a pair of electrodes, a substrate and a gaseous polymerizable substance which is deposited on the substrate and one of the electrodes, confining the glow discharge adjacent the one electrode and then applying an electric potential across the electrodes to sputter the material deposited on the one electrode and redeposit it in polymerized form on the substrate. The gas is a monomer or a gas which forms a polymer e.g. styrene or tetrafluoroethylene and an inert gas such as N 2  may also be added, the total gas pressure in the vacuum chamber being less than 100 microns. The glow discharge is preferably confined in a region adjacent an electrode by magnetic flux lines and an alternating electric potential > 3 and <60KHz is applied across the electrodes. The substrate which may be conductive, semiconductive or an insulator e.g. glass is placed midway between both electrodes so that both faces are coated and it may be moved between the electrodes during deposition. In one embodiment shown in Fig. 1, a substrate 14 is placed between electrode assemblies 15, 15' comprising mounting Al on stainless steel plate 20 and Al electrode 30 which may be perforated. Magnets 26, 27 are mounted on the plate 20 to confine the glow discharge and polystyrene or P.T.F.E. may be deposited from styrene or tetrafluoroethylene respectively. The polymer coating may also be doped by sputtering some of the electrode material.

Abstract: 434,215. Display boxes. JOHNS, SON, & WATTS, Ltd., and JONES, G. T., 40, City Road, London. March 16, 1934, No. 8321. [Class 18] A display box of cardboard &c. comprises more than two trays 1, 5, 6, Fig. 1, arranged in two or more superposed tiers and pivoted together on flexible vertical hinges 3, 4, with spaced axes so that one tray can lie immediately above another tray in the closed box, or the trays can be opened out to expose their interiors. The trays 5, 6 are pivoted to an extension 2 on the back wall of tray 1, and they carry flaps 7, 8 which overlie the front wall of tray 1 when the box is closed. A flanged lid 9 which holds trays 5, 6 in the closed position is also hinged to extension 2, or each tray may have its own lid and the trays 5, 6 can be locked together by a projection on the front wall of one tray engaging the front wall of the other tray. The trays 5, 6 may be disposed under tray 1, and the box may be circular hexagonal, &c. The trays may be secured to various parts of a board 17, Fig. 4, which forms the side walls of the closed box and which, when opened out, displays the trays as shown. Tray 18 might also be hinged to the front end 16 of the board. Modifications of this embodiment employing five rectangular trays and three circular trays are described. In a modification, the trays 5, 6, Fig. 6, are hinged to the front wall of the bottom tray at points 24, 25, and further trays 28, 29 carrying side wall extensions 34, 35 which are connected to the trays 5, 6 at hinge points 30, 31. Trays 28, 29 carry extensions 37, 38 hinged together at 41 and these extensions are formed with flanges 39, 40 which overlie the bottom and side walls of the closed box. The lid 32 is in two parts hinged together at 33, each part also being hinged to a tray 28 or 29. According to the Provisional Specification, the box comprises two trays which may be of semicircular form, hinged together on a wall extending from one of the trays, and where the upper tray is in two parts, these parts may be hinged about their adjacent corners. In a modification, the box comprises a circular upper tray and a lower tray composed of two semicircular parts with upwardly extending rear semicircular walls hinged to the side wall of the upper tray which has a back depending wall. The underneath trays are retained in position by a wall depending from the lid of the upper tray.

Filed: 1974-02-25
Abstract: 1431523 Container inlets FORD MOTOR CO Ltd 25 Feb 1974 [2 March 1973] 8429/74 Heading B8T [Also in Division B7] An insert 13 positioned within the inlet of a container, when used in combination with a nozzle having automatic shut-off means when contacted by liquid, prevents the unintentional filling of the container with liquid from a nozzle having a cross-sectional dimension greater than a predetermined dimension, but permits filling with liquid from a nozzle having a cross-sectional dimension equal to or less than said predetermined dimension. The insert 13 comprises an end portion 21 having an opening 23 therein to receive a permitted nozzle 29 but reject other nozzles 31, 33, and abutment means in the form of ramps 25 to engage the delivery end of a nozzle such as 31 and to space said delivery end from the opening 23. The insert is intended for use on automobile fuel tank filler pipes to prevent filling of the tank with leaded fuel when the automobile is filled with a catalytic converter. In use, when an oversize nozzle 31 is inserted in the filler pipe, the end of the nozzle engages the ramps 25. The flow of liquid is disturbed by the ramps causing the liquid to well up in the cylindrical portion 17 upstream of the opening 23. The automatic shut-off sensor of the nozzle is actuated and flow ceases. The insert 13 is preferably welded into the filler pipe and is provided with vent holes 19.
