Patent GB-397554-A (GB)
Title: Coating compositions
IPC: C09D101/08
Filed: 1932-02-26
Abstract: A synthetic resin is prepared from coconut oil, diethylene glycol, glycerol and phthalic anhydride.  Specification 363,333 is referred to.ALSO:Compositions for coating electric cables and wires consist of a cellulose derivative, such as cellulose nitrate, acetate or ether, a softener and a relatively non-volatile mineral oil which is incompatible with the cellulose derivative and exudes to form an oily film when the composition is dried; natural or artificial resins may be included in the composition.  Solvents of the usual type are employed and the softener may be such as to exert a solvent action on the cellulose derivative.  Preferably, the softener is of the solvent type and is one which is incompatible with the mineral oil, e.g. tricresyl phosphate, triacetin, benzyl ether, diethyl, and dibutyl tartrate.  Non-solvent softeners, such as castor oil and other semi-drying oils, butyl stearate, and ethyl palmitate, may be used but with a larger proportion of mineral oil.  With 10 parts of cellulose nitrate and 5 to 15 of softener, 0,2 to 1,0 parts of mineral oil are required and with cellulose acetate 0,1 to 0,5 parts of mineral oil for each 10 of acetate; cellulose ether requires 1,5 to 2,5 of mineral oil per 10 of ether and the softener must be incompatible with the mineral oil which is preferably highly purified and viscous.  Examples are furnished and in one of them a synthetic resin is employed which is prepared from coco-nut oil, diethylene glycol, glycerol, and phthalic anhydride.  Specification 363,333 is referred to.ALSO:Compositions for coating electric cables and wires consist of a cellulose derivative, such as cellulose nitrate, acetate, or ether, a softener and a relatively non-volatile mineral oil which is incompatible with the cellulose derivative and exudes to form an oily film when the composition is dried; natural or artificial resins may be included in the composition.

Title: Furnace installation
Filed: 1956-02-24
Abstract: 789,715. Combustion apparatus. STAMICARBON N.V. Feb. 24, 1956 [Feb. 26, 1955; Sept. 26, 1955], No. 5861/56. Class 51 (1). A solid fuel fired furnace installation comprising a water-jacketed hopper 1, a vertical combustion chamber 2 through which combustion air is adapted to pass horizontally and a grate 9 associated with ash removal means 10 is adapted such that, if necessary, the chamber 2 may be partitioned by a removable and apertured grate-like wall 21. In Fig. 1 the wall partitions the chamber 2 such that the combustion space is between walls 21 and 5, the latter, like the front wall 4 and the wall 21, comprising vertical water tubes joined at top and bottom by suitable headers and provided externally with fins 6 for preventing fuel passing between them. The wall 21 is removably joined to the furnace water-cooling system by a conduit 23 at each end of a top header 22 connecting with its associated hopper side wall and by a conduit 27 and a connecting tube 28 which joins bottom header 25 to the bottom header 8 of the wall 4. Combustion air is supplied by a fan 11 to a space 12 from which it is passed in quantities dependent upon the position of a damper 13 to conduits 16 and 18 for issuance into the secondary combustion chamber 19 and to a chamber 15 for passage horizontally through the walls 4, 21, and the fuel in the chamber 2. Some air from the chamber 15 may pass through a regulated aperture 20 to flow either over or under the grate 9 before passing up the chamber 2 to the fuel therein. A plate 29 prevents fuel from the hopper falling into the space between walls 4, 21 and a plate 30 prevents air from passing directly through the wall 4 to above the grate 9. In Fig. 3, the wall 21 is removably joined centrally to a conduit 34 connecting the hopper side walls and at both ends of its header 25 to a water space 36 of the furnace. Each connection to the space 36 has a cover 37. The space 38 between walls 21, 5, is closed at the top by a plate 39 and the plate 29 is used to direct fuel to the combustion space. A plate 40 prevents direct air flow under the grate 9 and up into the space 38. The secondary air conduit 16 has an additional air distribution conduit 18<SP>1</SP> which is removed on removal of the wall 21. Specifications 698,097, 698,098, 698,099 and 698,100 are referred to.

Title: Hydraulic telescopic shock absorbers
IPC: F16F9/48
Filed: 1957-02-21
Abstract: 861,162. Hydraulic shock absorbers. DE KONING, A. A., and DE KONING, K. K. K. Feb. 21, 1957 [Feb. 24, 1956], No. 5939/57. Class 108(3). A piston 3 (Fig. 2) and piston rod 6 are rigid with a piston valve member 5 which operates in conjunction with ports 10 in the cylinder wall leading to an annular reserve chamber C. The chamber C is also connected with the cylinder by means of a spring loaded valve 11. The piston valve 5 is provided with open ports 14 between its opposite faces. A valve 13 permits flow through the piston 3 on inward movement of the piston rod 6, only. In a modification (Fig. 1, not shown), the piston 3 is omitted and there is a conventional base-valve assembly between the cylinder and the chamber C. In a modification of the latter construction the valve 11 is mounted in the piston valve 5. In another modification of the construction of Fig. 2 (Fig. 5, now shown), the positions of the piston 3 and piston valve 5 on the piston rod 6 are interchanged and there is a base valve assembly as in the construction of Fig. 1. In the latter construction, the piston 3 is by-passed by passages disposed in the wall of the cylinder. In Fig. 5 the piston 3 is formed with a diametrically opposed pair of peripheral recesses 25 which are staggered both radially and axially with respect to a pair of similar recesses 17. The recesses 25 are each connected by ports 36 controlled by one way valve 37 with the cylinder space a above the piston 3 and by ports 14 with the cylinder space below the piston. The recesses 17 are connected by ports 24 with the outlet side of a valve 18 which is spring loaded against the outlet of a passage 23 leading to the space a. The arrangement is such that in operation, when the piston is moving either inwards or outwards away from the normal position relative to the cylinder, there is no damping action. When the piston is moving either inwards or outwards back to the normal position there is a damping action.

Abstract: 754,736. Automatic control systems. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Feb. 1, 1955 [March 1, 1954], No. 6010/54. Class 38 (4). [Also in Group XL (c)] In a radar system (see Group XL (c)) a mirror 20<SP>1</SP> freely attached to an aerial structure is automatically maintained parallel to a fixed mirror 20 by photoelectric means. As shown a light source 30 projects a beam of light through lens 31 on to the underside of mirror 20<SP>1</SP> and this is reflected back through the same lens to pass through a semi-silvered 45 degree mirror 31A to the second mirror 20 which is accurately horizontal and fixed to the ground. Mirror 20 reflects back the light to mirror 31A whence part is reflected to a photo-cell 32 on to which the light is focused, the output from cell 32 being applied through an amplifier 33 to a solenoid 34 pulling against a spring 35 and controlling the inclination of mirror 20<SP>1</SP>. The transmission/reflection ratio of mirror 31A depends upon the angle of incidence of the light thereon and is substantially unity when said angle is equal to 45 degrees so that when the two mirrors 20 and 20<SP>1</SP> are parallel, approximately one quarter of the light reflected downwards by mirror 20<SP>1</SP> will reach the cell 32 but any departure from this condition changes the energization of the cell 32 causing an automatic restoration of parallelism.

Title: Improvements in electric switches
IPC: H01H71/52
Filed: 1924-03-10
Abstract: 233,094. Mudie, A. B. March 10, 1924. Automatic circuit-breakers etc.; switches, actuating; latching. - In an automatic circuitbreaker, the operating lever of the switch is associated wtih an actuating disc having two notches in its periphery and a connection with the switch arm or with mechanism controlling it. A separate connection between the lever and disc is formed by an operating catch which engages one of the notches, while a releaseable retaining catch engages the other notch for holding the switch closed, the operating catch disengaging the retaining catch from its notch on a releasing movement of the operating lever. The forked handle 15 is pivoted at 5 and carries a catch 9 the forked part of which carries a pin or roller 19 adapted to engage a notch 8 in an actuating disc 4 to close the switch. The disc is connected by a pair of links 12 to the switch arm and has a notch 10 adapted to be engaged by a catch 11 to hold the switch closed. At or near the closed position the tail 20 of the catch 9 overlaps the tail 24 of the catch 11, so that operation of the automatic release 26 engages the tail 20 which engages the pin 25 to remove the latch 11 from the notch 10 and open the switch. Reverse movement of the handle 15 when the switch is closed will open the switch owing to the curvature of the tail 20, which engages the pin 25, and to the movement of the pin 19 out of the, notch 8. If during closure the release 26 operates before the catch 11 engages the disc, it will engage the tail 20 and so free the disc and allow the switch to open, the opening movement being limited by the links 12 engaging the boss 7 on the disc. The disc may be fixed on the switch-arm spindle and operated thereby, or the disc may operate a number of switches.
