Title: Improvements in producing metal to metal bonds with structural adhesives
Inventor: DICKSON ERIC WINSTON
IPC: B29C65/48
Filed: 1962-05-22
Abstract: 964,298. Jointing. ASSOCIATED ENGINEERING Ltd. May 21, 1963 [May 22, 1962], No. 19678/62. Heading B3V. A method of making metal to metal bonds with structural adhesive comprises placing the parts together with an adhesive therebetween and supplying current to the parts, which are used as electrodes, to generate heat in the adhesive without appreciably raising the temperature of the parts. In a preferred embodiment a H.F. generator is isolated from and capacitatively coupled to one or both of the parts by a low loss dielectric material to safeguard the generator against a short-circuit should the parts touch. The adhesives may be mixed synthetic resins, rubber and resin, phenolic and polyvinyl formal powder, or thermoplastic adhesives. Accelerated evaporation of any solvents contained in the adhesive may be achieved by rapid local heating of the parts prior to the bonding operation. Gauze or an unwoven mat of " Terylene " (Registered Trade Mark), or nylon may be inserted between the parts to improve the loss factor of the adhesive and also reduce the risk of the parts touching when pressure is applied during heating. The method may be used to bond metal brackets, stiffeners, fixing lugs which may or may not be plastic-coated to pressings made from plastic-coated metal sheet or metal studs, brackets to the steel side of plasticcoated sheets. Alternatively, the adhesive may be resistance heated by applying an appropriate voltage from a 50-cycle mains supply.

Abstract: 1431662 Silencing gaseous flow DONALDSON CO Inc 25 April 1973 [28 April 1972] 19711/73 Heading F1B [Also in Divisions H3-5] Acoustic energy of a predetermined wavelength in a fluid-flow in a duct 17 is coupled into a chamber 19 through holes 20 or diaphragms, in the separating wall, of a size and spacing such that the phase of a wave is shifted , the wave travels in the same direction in the chamber and substantially no acoustic energy of the wave returns the holes or diaphragms during coupling. The centres of the holes or diaphragms are spaced apart along the duct by, an odd multiple of one-quarter of the predetermined wavelength. The chamber 19 may contain acoustic energy absorbing material 21, e.g. fibreglass. Several chambers 19 may be coupled to the duct 17 along its length, each for a particular wavelength. The chamber 19 may be formed by a duct connected to the duct 17 for fluid-flow from the downstream end of one to the upstream end of the other, Fig. 4 (not shown), or as a duct open at one end but closed at the other, Fig. 5 (not shown), to provide partial or complete acoustic reflection. The sizes of the holes 20 or diaphragms may be calculated or determined experimentally, one example being given in the Specification. The coupling arrangements may be used for silencing internal combustion engine intake or exhaust systems and be combination with other types of silencing.

Title: Method of augmenting the output of electric cells
IPC: H01M10/44
Filed: 1927-07-25
Abstract: 274,907. Furness, G. C. July 23, 1926, [Convention date]. Drawings to Specification. Dry cells, regenerating.-The life and energy output of intermittently used dry cells are augmented by passing therethrough a reversed current, insufficient to cause damage, in the rest periods. The reversed current may be applied after the first or after a number of discharge periods but before the major part of the energy output of the cell has been discharged. The current used is considerably smaller than the safe discharge current. The amount of energy supplied is preferably in excess of that discharged up to the time, and is greater when the discharge rate is low. Manual or automatic switches may be provided to connect the cell in turn to the load and the reversed current source.

The burner 16 projects into a chamber 2 bolted to the front of the furnace and provided with a flaring flame outlet member 5. The front wall of the chamber 2 is provided with a central opening 6 and air inlet openings 7 controlled by a shutter plate 8. The opening 6 receives a tubular bracket 10 which is secured by a nut 11 and upon the bracket 10 is mounted an adjustable bracket 13 presenting spaced lugs 14 which receive the burner tube supports 18, 19, the support 19 through which atomizing air is supplied being provided with a screw threaded nut in the form of a handwheel 21 by which it is moved axially to release the burner. Atomizing fluid is admitted to a passage 33, Fig. 5, in the wall of a cylinder 30 and passes through a port 30<1> to the top of spring-loaded piston 29 which is connected by a piston rod 28 and crank 27 to the spindle of a damper 25 for controlling admission of air to the furnace. The upper end of the passage 33 is connected by a pipe 34 to a tubular member 32 having a regulating valve for controlling the supply of atomizing fluid to the burner. A pipe 56 leads atomizing fluid to the control unit 45 where it acts upon the end wall 52 of a collapsable bellows member 49 to open the spring-loaded valve 55. Before entering the control unit the liquid fuel is heated in a chamber 35 provided with an electric immersion heater 41 and a thermostat 39. The heated fuel passes through a strainer in a chamber 42 and thence through a passage 47 to the regulating valve 57 of the control unit. Ignition devices are provided at 22.

Title: Fluid pressure operated reciprocating motors
IPC: F15B11/15
Filed: 1972-05-01
Abstract: 1444351 Hydraulic or pneumatic reciprocating motors BUTTERWORTH HYDRAULIC DEVELOPMENT Ltd 31 July 1973 [1 May 1972] 20155/72 Headings F1A F1M and F1S In a hydraulically or pneumatically operated single or double-acting motor, e.g. of the kind described in U.K. Specification 1283525 wherein a spool valve 1 controls the reciprocations of a motor piston 21 in a cylinder 3 and the piston 21 co-operates with ports in its cylinder 3 to change the pressure applied to the spool 7 of the valve and thus cause its automatic changeover, at the extreme end of the stroke of the piston 21 in at least one direction fluid is trapped in the cylinder ahead of the piston in order to assist in the reversal of the piston and dissipate the kinetic energy of the piston and its load. The sequence of operation of the double-acting motor shown is generally the same as described in the aforesaid Specification and will thus be described only briefly. With the spool 7 in the position shown, the piston 21 moves in the direction of arrow A under the influence of pressure fluid admitted to piston chamber 25 via passages 32, 35, 42, 84 and a non-return valve 86. Exhuast from the opposite piston chamber 26 takes place through a port 63, a passages 62, a transfer chamber 20 around the spool 7 and an outlet 47. Just before the piston land 23 closes the port 63, a piston recess 28 communicates, via diametrically opposite ports 46, 74, the chamber 26 with a spool working chamber 13a and a spool biasing chamber 17. This causes the spool to move to its opposite end position and initiate a reverse stroke of the piston 21. However, the piston's enertia causes it to continue to move in the same direction resulting in the recess 28 entering a bore 21b thereby isolating the chamber 26. The fluid trapped in the chamber 26 rapidly decelerates the piston and then reverses its direction, the resulting fall in pressure in the chamber 26 allowing a non- return valve 85 to open and admit fluid from a passage 45 now pressurized due to the changed position of the spool 7. An electrically controlled valve actuated just before the piston covers the port 63 and operable to cause changeover of the spool valve may replace the arrangement constituted by the ports 46, 74 and the recess 28. If desired the ports 46, 74 may be axially displaced whereby a modified changeover of the spool 7 is effected. Reversal at the other end of the stroke  is accomplished in an analogous way. The motor is prevented from stalling in an end of stroke position by throttled passages 76, 78 which, should such a condition occur, deliver fluid (directly from inlet 32 or, as shown from the pressurized end of the cylinder 3) to the ports 46, 74 or 43, 72 whereby the spool is caused to reverse. Stalling of the piston 21 in a central position is prevented by making spool biasing chamber 17 of greater effective area than the biasing chamber 15.
