Title: Windscreen wiper
IPC: B60S1/06
Filed: 1928-08-18
Abstract: 321,715. Morris Commercial Cars, Ltd., and Hamill, W. W. Aug. 18, 1923. Vacuum engines. - A method of operating windscreen wipers for motorcars consists in the utilization of negative pressure in the induction system of the engine and positive or negative pressure derived from the exhaust, so as to produce a reasonably constant force. An engine 1 having an induction system 2, Fig. 1, and an exhaust 3, is connected to a wiper motor 4 by pipes 6, 7, 8 so that while one of the motor cylinders is under suction the other is under pressure from the exhaust. A cleaner and cooler apparatus 5 is provided. The wiper motor may be of the air operated type having two coaxial cylinders a, b, Fig. 2; between which is placed a valve c, Fig. 4, with ports e, f, g communicating with the induction and with the two outer ends of the motor cylinders. To introduce exhaust gases, an annular cavity h is formed in the slide valve and an additional port i, Fig. 5, communicating with the exhaust. The middle part of the valve has a cavity i intermediate to the annular exhaust gas cavity h. From the position shown in Fig. 5, the valve connects one of the motor cylinders with the exhaust and the opposite cylinder with negative pressure from the induction system. The usual cup leathers k, Fig. 2, are supplemented by two others l, as positive and negative pressures are used. At the end of the stroke the transfer valve is tripped, and the pistons move in the opposite direction. To prevent ignition of gases a device such as Fig. 3 may be used in which a container m has an inlet n with a pipe p and an outlet o for the exhaust. Safety gauze q is secured by plates r and nuts s. Cooling ribs v may be provided to reduce the temperature of the exhaust gases. In another method of working, Fig. 7, exhaust gases or a portion thereof, are made to produce a vacuum effect similar to that of the induction, and a device, Fig. 8, is provided for transferring whichever source of vacuum is higher. This method has the advantage that a standard pattern windscreen wiper may be used. The induction system is shown at 2, Fig. 7, the exhaust 3 with pipes 9 and 10 connected to a transfer device and so by a pipe 11 to a standard pattern wiper 4. The transfer device, Fig. 8, may comprise a cylinder wand a plunger x with a reduced waist y. Three ports are provided, z at one end of the cylinder, a<1> at the other, and b at the middle. The outer ports are connected by unions c<1> and pipes 9 and 10 with two sources of vacuum, while the middle is connected to the wiper. If the vacuum produced from the exhaust pipe 10 is greater than that by pipe 3 the valve will move to the right, and the wiper will be subjected to the greater vacuum. Various methods of obtaining vacuum from the exhaust e<1> may be used, such as shown in Figs. 9, 10, 11 where g<1> is the vacuum.

Title: Improvements in or relating to adhesive-moisteners
IPC: B43M11/00
Filed: 1946-08-13
Abstract: <PICT:0615831/III/1> <PICT:0615831/III/2> <PICT:0615831/III/3> An apparatus for moistening adhesive surfaces on labels and the like has a movably guided tray associated with a label-supporting table-plate pierced by a multiplicity of perforations and also connected with a pump in such a manner that when the tray is moved the pump is actuated to deliver liquid from a reservoir to the tray and thence through the perforations in the table-plate to the label-supporting surface of the latter.  Referring to the diagrams, when the apparatus is not in use the liquid level inside the pump cylinder 42 is the same as that in reservoir 1.  The label is applied to table-plate 7 with adhesive side down and the table-plate depressed.  This causes tray 40 and pump piston 31 to work against spring 48 and the pressure exerted on the liquid in the cylinder between piston 31 and valve 50 forces the liquid through bore 54 of piston-rod 32 to fill channels 56, vertical bores 57 and the gap between liner-plate 55 and perforated table-plate 7 to emerge through the perforations.  When the hand pressure is released, spring 48 restores the apparatus to its original position.

Abstract: 893,676. Making composite containers; jointing. BRISTOL AEROPLANE PLASTICS Ltd. Oct. 26, 1959 [July 28, 1958], No. 24238/58. Classes 83 (2) and 83 (4). A method of assembling a lap-jointed structure of sheet metal is characterized in that the sheet metal parts are held in assembled overlapping relation with a layer of pervious material between the opposed faces of the lap joint and a settable free-flowing liquid binder capable of adhering to the sheet metal parts is caused to flow into and to fill the interstices of the pervious material and to set. In an embodiment a container is made with overlapping joints according to the invention by providing flanged side panels 11 and 12 and joggled side panels 13 and 14 (Fig. 2). The bottom of the container is formed from an upwardly flanged panel 15 (Fig. 1). The panels are covered with a cloth coating 16 composed of e.g. acrylic or polyamide fibre bonded with an epoxy resin or glass fibre or jute bonded with a polyester resin. The panels and their cloth coverings are assembled in a collapsible mould 18, the bottom 17 of which is provided with an opening 19 through which the resin binder is supplied. A flexible bag 21 of rubber or polythene filled with liquid or granular material is used to keep the panels in place. Resin binder is also supplied through a pipe 22 leading to the bottom of the bag. When the resin has had time to seep through the cloth coverings and emerges at the top edge of the mould, the resin supply is shut off and the setting is accelerated by warming the assembly. Alternatively, the impregnation of the cloth may be effected by suction in which case no filling material is required in the bag. In a joint between two double walls (Fig. 3), each wall consists of metal sheets 24 and 26 separated by a pervious insulating material 28 enclosed in an impervious skin 30 of hardened resin impregnated cloth. The metal sheets are covered on both faces with cloth 32 as hitherto and a piece of cloth 34 is inserted in the joint between the insulating material. After assembly the cloth 32 and 34 is impregnated with resin which is then caused or allowed to set. In another embodiment the cloth 26 is confined to the overlapping joints of the assembly as shown in Fig. 4 and the side edges of the joints are sealed by adhesive tapes 27 and 28.

Classes 38(3) and 38(5) A reversing switch for a motor, especially that of a garbage disposal unit, comprises two contact-carrying plates 36, 44 co-axial with the shaft 30, the plate 44 being movable axially by centrifugal means and angularly by direction responsive means. The plate 44 is carried by a sleeve 42 and is urged upwards to separate the contacts by a spring 46. Plate 36 is fixed and carries contacts 70, 72, 76, 78 connected in pairs by members 74, 80, the plate 44 having contacts 100, 102. A frame 120 secured to the shaft carries weights 126 normally urged to the Fig. 6 position by springs 130. When the shaft is stationary, a plate 40 is forced downwards by weights 126 to close the contacts, Fig. 6, which are in circuit with a starting winding. As the motor speeds up. the weights fly out and release the plate 40 which with plate 44 moves up to open the starting circuit. When a main switch (not shown) is opened, the shaft slows down and weights 126 depress the plate 40 again, at the same time rotating it and plate 44 by friction in the direction of rotation to an extent limited by a pin and slot connection 52. 54 between plates 36, 44. Contacts 100, 102 are thus rotated so as to be opposite a different pair of the fixed contacts so that when the reversing switch is again closed, the motor is reversed, for example, contacts 100. 102 may engage 78, 70 respectively. instead of 72, 76.
