Title: Improvements in servo-brake mechanism for vehicles
IPC: B60T13/24
Filed: 1931-01-16
Abstract: 371,831. Fluid-pressure brakes. ASH, R. G. V., Hemp Gill, Frodsham, Cheshire, and BUCKLEY, R., Oaklea, Poulton-le- Fylde, Lancashire. Jan. 16, 1931, No. 1469. [Class 103 (i).] In a vacuum brake for motor vehicles the reaction on the operating pedal is obtained wholly from the cylinder the piston being employed solely for transmitting power to the brakes. The brake cylinder A is mounted on a link a and on a.pivot b on a lever B mounted on a fixed pivot b<1>. The brake pedal is connected by a rod C to the upper end of the lever B. The control valve H which is contained in the brake cylinder is controlled by a rod d<3> passing to the outside of the cylinder and connected to.a lever D pivoted at d to the lever B and connected to rod E. Rod E and a rod G leading to the brakes are both pivoted on a pin f carried by a lever F connected to the brake piston A<1> by a link f<2>. The valve H is adapted to pivot about either of two semispherical closure members h<1> or h<2> which control the ports a<3>, a<4> leading respectively to the induction pipe of the vehicle engine and the atmosphere. A spring h<3> keeps the closure members in position over the ports. In view of the mounting of the cylinder on the link a and the lever B the tendency of the cylinder to move in the opposite direction to the piston will exert a reactionary pull on the lever B and rod C. The brakes may be applied directly through rod C, levers B, D and rod E. The cylinder may be stationary and the pivot f<1> of the lever F connected by leverage to the rod C.

Abstract: 930,015. Dispensing liquids by gaseous pressure; pipe connections. GASKELL & CHAMBERS Ltd. Dec. 8, 1961 [Jan. 13, 1961], No. 1470/61. Classes 99(1) and 102(2). In valve and coupling means for a liquid container, e.g. a beer barrel, a closure member 12 is spring-loaded into a position preventing flow through liquid outlet ports 16 in a dip tube 11 and gas inlet ports 17 in the valve body, and is axially movable to permit such flow by the attachment of a tapping head. Upward movement of closure member 12 is limited by a member 15 on dip tube 11. A gas connection, e.g. for carbon dioxide, on the tapping head communicates with ports 17 via a passage 27 when member 12 is in its open position. Catches 29 engage under a lip 30 to locate the tapping head.

Title: Improvements in selective coupling circuits for use at radio frequencies
IPC: H03H7/01
Filed: 1946-01-16
Abstract: 606,821. Valve circuits. HARTLEY, K. A. Jan. 16, 1946, No. 1494. [Classes 40 (v) and 40 (vi)] A resonant circuit for coupling two points with stray impedances 23, 26 to ground comprises an inductance 21 shunted by a tuning capacitance and with a centre-tap which is connected to a point of zero A.C. potential. This arrangement places the stray capacities 23, 26 across the tuned circuit in series with each other; and so minimizes their effect. As an inter-valve coupling, it also permits of neutralization of the valve 20 by the connection of a condenser between the two anodes 19, 20, Fig. 7 (not shown). The balance of the circuit to ground is adjusted by means of a condenser 60 in parallel with the capacity 23 or the capacity 26. Specification 456,002 is referred to.

Abstract: 859,193. Testing balance of wheels. LAYCOCK ENGINEERING Ltd. Oct. 7, 1958 [Jan. 17, 1958], No. 1634/58. Class 106 (2). [Also in Groups XXII and XXXIV] A wheel-supporting flange 10 for a wheelbalancing machine is formed with a number of radial recesses 11 each slidably housing an insert 12 adapted to be attached to the wheel to be supported, an aperture 16 in the base of each recess 11 and screws 14 for clamping each insert in any position along the length of the recess, each insert 12 being formed with an index mark 19 adapted to be set against graduations 18 on the face of the flange 10. The recesses 11 are slightly greater in depth than the inserts 12 each of which is formed with two tapped holes 17 to accommodate wheel studs so that each setting of the inserts 12 deals with two sizes of pitch circle for a wheel. Each index mark 19 is on the centre line of a tapped hole 13 in which the screw 14 is received. Further subdivision of the range of sizes may be made by the use of a second index mark 21. The inserts 12 are interchangeable so that different inserts may be used for different wheel studs. The wheel 20 is secured by nuts 25 to the flange 10 which is secured by tapped holes 23 to the balancing- machine. In a modification the radial recesses extend to the periphery of the flange to allow the inserts to protrude from the flange to avoid the flange becoming too cumbersome when used for wheels having a large pitch circle.

Title: Improved method of and means for preventing or hindering corrosion of zinc, zinc alloy or zinc coated parts in water systems
IPC: C23F13/02
Filed: 1942-02-07
Abstract: 554,046. Preventing corrosion. BRITISH NON- FERROUS METALS RESEARCH ASSOCIATION, LIDDIARD, E. A. G., KENWORTHY, L., and FRAPWELL, S. A. Feb. 7, 1942, No. 1655. [Class 123 (i)] Corrosion of zinc or zinc-coated pipes or tanks in water systems, due to the solution of a minute amount of copper from other parts of the system, and subsequent deposition of copper on the zinc, is prevented by freeing the system from dissolved copper. Solution of copper may be prevented by maintaining a concentration of about 0.05 parts of zinc salt per hundred thousand parts of water. Water which has been in contact with copper or copper alloy may be caused to flow over a zinc surface, e.g., a filter containing zinc turnings, which is thereby corroded, before the water reaches the parts to be protected. The added zinc surface may be electrically connected to the copper or copper alloy to provide cathodic protection for the latter, e.g., by inserting short lengths of galvanised piping into a copper or copper alloy piping system, or by coating the ends of the copper pipes with zinc, or by inserting sleeves of zinc at regular intervals.

Title: Condition-monitoring system
Inventor: ROWELL WILLIAM GRANT
IPC: G08B17/02
Filed: 1966-01-13
Abstract: 1,104,226. Monitoring alarm systems. SCULLY SIGNAL CO. 13 Jan., 1966, No. 1689/66. Heading G4N. In an arrangement for automatically checking a monitoring system, the current through the sensing element is repetitively varied to produce a checking signal, failure of which indicates a circuit fault. Normal condition.-Assuming relay 57 is unenergized, contacts 40, 16 are closed charging capacitor 15 from source 11, contacts 41, 22 are closed energizing relay 18 and contacts 28, 44 are open. Contacts 50, 42 close completing circuit to detector 51 which commences to heat up. As it heats its resistance falls until relay 53 energizes closing its contacts 43, 55 to energize relay 57. Contacts 44, 28 close shorting detector 51 thus allowing it to cool, and contacts 41, 22 open. After a delay due to capacitor 23 relay 18 releases causing relays 53 and 57 also to release. Contacts 44, 28 then reolose and the cycle repeats. As relay 57 pulses, change over of contact 40 between contacts 29, 16 causes capacitor 15 to alternately charge from source 11  and discharge through relay 32, the relay being held energized during the charging period by capacitor 33. Abnormal condition.-Any fault in the circuit will modify the pulsing rate of the relay 57 and relay 32 will release to initiate an alarm signal. With an abnormally high temperature condition present, the detector 51 will not cool down, when contacts 28, 44 are closed and actuation of relay 18 will cause relay 33 to operate immediately, again modifying the pulsing rate of relay 57 to allow relay 32 to release.

Abstract: 790,721. Abrasive brushing. REYNOLDS METALS CO. Jan. 23, 1956 [Feb. 9, 1955], No. 2179/56. Class 60. [Also in Groups XXII and XXXV] An electric transformer or like apparatus has windings 67, 68 composed of strips of aluminium cut from a sheet, the strips being coated with electrically insulative material which covers the faces of the strip and the edges thereof. A convenient method of insulating the strip is to apply an anodic film to the surfaces thereof by means of an anodizing process but in order to ensure that the edges of the strip as well as the surfaces thereof take a film coating it is necessary to remove the microscopic burrs from the edges which result when cutting the strips from a larger sheet. A strip 20 which has been cut from a larger sheet by any conventional cutting process is wound to form a roll 88 on a mandrel shaft 89 from which it is pulled and rewound. During the passage of the strip 20 from the roll 88 to the rewinding means the upper edges of the strip are engaged by a pair of oppositely revolving circular brushes 90, 91 whilst the lower edges are engaged by a similar pair of brushes 96, 97 back up blocks 95, 98 being provided to permit an appreciable amount of brushing without applying an undue amount of tension to the strip. The brushing forces are exerted on the edges at an angle and a suitable abrasive-preferably of 200 mesh-is used, the brushes being composed of bronze filaments or fibres as required. After brushing the edges of the strip are smooth and as shown in Fig. 4 and after being chemically and mechanically cleaned are chemically polished in an aqueous solution of acid at 170‹-200‹F. The solution may comprise a mixture of phosphoric and nitric acids and the chemical polishing treatment of 1-2 minutes duration. The strip is then subjected to an anodizing treatment for 6-13 minutes in an aqueous solution of sulphuric acid at 70‹F. with direct current at a density of 25-30 amperes per square foot of strip area. The insulated strip is then sealed first by immersion in hot water at 200‹F. and then by immersion in steam and lastly coated with silicon.
