Title: Improvements in or relating to film-forming compositions
Inventor: WHITE THEODORE
IPC: C09D5/08
Filed: 1957-08-28
Abstract: Tannates of metals for use as anti-corrosive pigments in paints (see Group III) are prepared by mixing an aqueous extract of a tannin with a metal oxide or an aqueous solution of a salt of the metal and filtering off the product.  The metal may be lead, iron, zinc, barium, aluminium or copper, and the tannin may be an extract of mimosa, chestnut, quebracho, quebracho (soluble), myrabolam or valonea.  Examples are given of reacting an aqueous mimosa extract with (1) lead acetate solution, and (2) litharge.ALSO:An anti-corrosive non-aqueous film-forming composition contains as a pigment a polyvalent metal compound of a naturally occurring tannin extract.  The metal may be lead, iron, zinc, barium, aluminium or copper; suitable tannins are those from mimosa, chestnut, quebracho, quebracho (soluble), myrabolam and valonea. In examples, paints containing mimosa salts of various metals, and lead salts of various tannins are compared with each other and with red-lead and iron-oxide paints.  The lead compound formed from mimosa extract is shown to be the most effective corrosion inhibitor.

Title: Improvements in or relating to automatic braking circuits for a.c. induction motors
Inventor: BURNARD CYRIL LAWRENCE
IPC: H02P3/24
Filed: 1969-05-29
Abstract: 1283776 Induction motor braking circuit PLESSEY CO Ltd 28 May 1970 [29 May 1969] 27307/69 Heading H2J A split-phase induction motor M with main winding M1, and auxiliary shaded winding M2 is braked by discharging a capacitor C3 through the windings via a silicon controlled rectifier MR2 triggered when the motor contacts RLA/1 and SB are both opened. The capacitor C3 is charged to a voltage exceeding the input voltage by that induced across M2, via resistor R1 and diode MR1. The triggering circuit C1, R2, R3, R4 and diode MR3, shunted by the motor contacts is rendered operative when the latter open so that capacitor C1 provides a triggering pulse to electrode MR2X when the voltage at terminal 2 rises. R4 prevents triggering for low voltages across C3. SB is a priming contact, and RLA/1 is closed by energization of relay coil RLA by contact SA, which is operated by a motor driven cam, and opens to stop the motor after a given number of revolutions. The capacitor C1 discharges through R2 after triggering, or if diode MR3 is omitted and replaced by diode MR3<SP>1</SP>, R2 may be omitted, and the capacitor discharges via R3, R4 and the motor contacts. Specific circuit component values are given for a 1/250 h.p., 8 pole motor.

IPC: F02P5/06
Filed: 1924-11-17
Abstract: 247,304. Royce, F. H. Nov. 17, 1924. Timing of the ignition in accordance with the engine speed is obtained by means of a centrifugal governor actuating the advance and retard mechanism through a relay device, such as a piston acted on by the pressure of the lubricating-oil as controlled by a valve connected to the governor. Hand control for starting and slow running is also provided, and in engines having both battery and magneto ignition the former is arranged to be advanced, considerably more than the latter by the hand control at starting, both systems being afterwards advanced equal amounts by the governor as described in Specification 247,897. The Figure shows a relay device comprising a piston valve d connected by a rod d<1> and lever a<1> to the governor sleeve a, and admitting oil under pressure from an annular chamber b<5> by way of ports b<1>, c<1>, passage d<3>, and ports c<2> to the underside of a piston c, which through a slide e and lever f actuates the timing-mechanism against the influence of a spring g. The movements of the piston c are limited in proportion to those of the valve d by means of ports c<3>, c<4>, through which oil escapes as soon as the ports c<4> move beyond the end of the valve d. Specification 17267/14 also is referred to.

A method of reading the result of an interrogation contained in a detector matrix 6 associated with an associative store (not shown), using an indicator arrangement which contains one indicator element (e.g. flip-flop) for each column and row of the matrix is characterized in that, in a first simultaneous reading operation involving all the detector elements of the matrix, only the indicator elements 8 associated with the columns of the matrix are operational (through AND gates 12, Fig. 4, not shown), and that, subsequently, the columns of the matrix containing the marked detector elements are interrogated individually and successively by logic switching network 9 (comprising AND gates, Fig. 4, not shown) in a second reading operation during which each of the indicator elements 7 (Figs. 5 and 6, not shown) associated with the rows of the matrix are operational. The detector matrix preferably comprises elements which may be non-destructively read or which have at least three stable states. Alternatively, each element may comprise paired bi-stable devices (e.g. ferrite toroidal cores) or even single bi-stable devices if the first reading is effected simultaneously with the associative interrogation itself.

Title: Improved manufacture of phosphorus in blast furnaces
IPC: C01B25/20
Filed: 1931-10-05
Abstract: In the blast furnace production of phosphorus, the charge consists of tricalcium phosphate, coal and an acid flux in hard lumps, e.g. burnt brick waste, having the composition 5SiO2, 1,5Al2O3.  Preferably the calcium phosphate is agglomerated with the coal by mixing and coking. The air enters the furnace at a temperature of between 450 and 550 DEG  C. and the reaction commences in a narrow zone just above the level of the tuy<\>geres and is completed in the slag.  The height of the charge above the tuy<\>geres should be regulated so that the emerging gases are at a temperature of about 400 DEG  C.  To prevent the slag from cooling, ferrophosphorus is added to form a layer below the slag, the ferrophosphorus being tapped off at intervals and returned in the charge.

Abstract: 425,844. Toy boats; games. GREENER, F., 134, Grange Road, Erdington, Birmingham. Oct. 11, 1933, No. 27968. [Classes 132 (ii) and 132 (iii)] An apparatus or appliance for playing a game or for serving as an amusing or instructive toy comprises a tank or similar liquid receptacle provided with one or more uniformly diverging channels and one, or a series of, light and thin buoyant objects adapted to be launched upon the water in the narrow end of one of the channels the boundaries of the channels and the edges of the floating objects being inclined or arranged so that the objects will be propelled, under the influence of capillary attraction towards the wider end of the channel. As shown in Fig. 5, an open tank containing water is constructed with a uniformly diverging but tortuous channel c<1> having vertical or inwardly inclined walls c. The channel opens into a " harbour " area c<2> containing structures representing, for example, a lighthouse f and a landing stage e. The walls of the lighthouse may be vertical or inwardly inclined and the walls of the landing stage outwardly inclined. Small thin objects of metal or other material, such as the object a<1>, Fig. 3, representing boats, when placed on the surface of the water at the small end of the channel c<1> proceed down the channel by reason of the capillary forces set up by the vertical or inclined walls and emerge into the harbour area where they are repelled by the lighthouse and attracted by the landing stage. The channel c<1> may be produced by two uniformly diverging wires in contact with the surface of the water. A wire, vertically adjustable, may be stretched, in contact with the water, from the mouth of the harbour to the opposite side to cause the boats to travel along the side of the wire. A tank with two or more channels may be provided for a race game and means may be introduced into the tank to enable the players to vary the speeds of the boats. Such means may consist of rudderlike contrivances hinged to the walls, or the walls may be hinged. Glass rods may be provided to attract or repel the boats by dipping the rods into the water at various angles adjacent to the boats. Instead of boats, metal representations of fish may be provided, and when two channels are provided in the tank, one competitor may endeavour to make his fish intercept and simulate swallowing that of the other competitor.
