Filed: 1963-10-07
Abstract: Alkaline washing compositions comprise an alkali cleanser (i.e an inorganic material which is alkaline in reaction and possesses cleansing properties) and an amino tri-(alkylidenephosphonic acid) of formula <FORM:1056177/C4-C5/1> wherein X and Y are the same or different and are H or C1-4 alkyl, or a water-soluble salt thereof. Specified alkaline agents are alkali metal and ammonium hydroxides and carbonates, preferably NaOH in a concentration of 1-20% of an aqueous composition.  The preferred amino tri-(alkylidene phosphonic acid) is amino tri-(methylphosphonic acid) in the form of its penta-sodium salt (see Division C2).  The phosphonic acid component of the compositions acts as a sequestering agent for metal cations (see Division C1).  The compositions are used to wash bottles and glassware and may contain an anti-corrosive agent.ALSO:Amino tri(methylphosphonic acid) is prepared by condensing diethyl phosphite with ammonia and formaldehyde in aqueous medium to give hexaethyl amino tri(methylphosphonate) which is hydrolysed with conc. HCl; the pentasodium salt of the acid is prepared by reaction of the acid with aqueous NaOH.ALSO:Compositions containing an amino tri-(alkyldene-phosphonic acid) of formula <FORM:1056177/C1/1> wherein X and Y are H or C1- 4 alkyl or a water-solubl salt thereof are used to sequester heavy metal ions (e.g. Fe+ + +, Fe+ +, Co+ +, Mn+ +) in aqueous solutions.

Title: Improvements in pumps

Filed: 1962-10-18
Abstract: 961,497. Centrifugal pumps. I. C. JENNINGS. Oct. 18, 1962 [Nov. 29, 1961], No. 39520/62. Heading F1C. A centrifugal pump is located within a receiver and close to the top wall of the receiver, a vertical suction pipe being connected at its upper end to the pump inlet and terminating at its lower end close to the bottom wall of the receiver, control means starting the pump when the liquid level in the receiver reaches an upper limit substantially level with the top of the pump casing and stopping the pump when the liquid level reaches a lower limit at or slightly above the lower end of the suction pipe, and means are provided for venting air trapped within the pump and suction pipe as the level in the receiver rises from the lower limit to the upper limit whereby to ensure priming. A motor-driven centrifugal pump 14 is attached to the underside of a cover plate 12 of a sump 10 and draws liquid from the sump through a suction pipe 23 which may be provided with a strainer 61. A switch 34 operated by a float 30 starts the driving motor when the liquid in the sump reaches an upper level 48 and stops it when the liquid falls to a lower level 46. The pump 14 is submerged in the liquid only when the liquid is at or near its upper level 48, and the pump bearings are always above the liquid. When the pump is stationary and the liquid level is rising, air trapped in the suction pipe 23 and in the pump escapes through the discharge pipe 50 and also through vents 36, 38, 40 and thence through a vent pipe 44 to atmosphere. The pump is therefore always primed when it begins to operate. A check valve 54 may be provided in the discharge pipe.

Title: Crayons
IPC: C09D13/00
Filed: 1977-09-26
Abstract: This article contains meltable and/or heat-curable synthetic resin as binder and from 5 to 50% by weight, based on the total quantity of resinous binder and pigment, of at least one colouring pigment. A pulverulent mixture is formed from the components of the article and this is pressed to form the article at below the softening or curing temperature, for example at room temperature. With this article, shaped in the manner of sticks of chalk, pictures can be produced which can be permanently fixed by the application of heat. Since this requires only temperatures up to about 200 DEG C, the fixing can be achieved with simple means, for example on a hot plate or in an oven.

As shown, the writing gun and lens system of Fig. 2, are arranged in a side arm 15, Fig. 1, of the tube and a flood gun 16 is accommodated in an indented portion 14 of the envelope. The storage screen 28, having a magnesium fluoride coating 32, is connected to a pulse generator 34, so that the storage surface assumes a quiescent potential that is negative with respect to ground to the extent of the pulse amplitude, at which potential all the flood electrons are prevented from reaching viewing screen 24.

Title: System for maintaining a diesel engine
IPC: F02B3/06
Filed: 1976-10-01
Abstract: 1505968 Monitoring engine timing SUN ELECTRIC CORP 1 Oct 1976 [3 Oct 1975]  40898/76 Heading G1N The timing of a diesel engine is monitored by measurements of the pressure in a fuel injection line using a pressure to voltage transducer 32, Fig. 3. The pressure signal is amplified at IC 1 and averaged at C2 in a network which suppresses short time peaks. The pressure changes produced at the instants of fuel injection are sensed at the pre-set tap of potentiometer P1 and compared at IC3 with the amplified voltage on capacitor C2 to produce a trigger pulse when the difference is positive. This triggers a first pulse generator 76, the output timing pulse at 90 being fed to a timing light 28 and to an oscilloscope 26 which also displays the fuel pressure waveform from amplifier IC1. The timing pulse is terminated when the voltage on a capacitor C4, charged primarily through a resistor R14, reaches a pre-set value. The trailing edge of the timing pulse is fed via capacitor C6 to trigger a second pulse generator 102. If a further timing pulse from generator 76 is produced before the end of the pulse from generator 102, which occurs when the engine speed is sufficiently high, diodes CR7, CR8 are reverse-biased, capacitor C9 is charged via resistor R19, and the voltage on C9 assists the charging of capacitor C4 to decrease the duration of the first timing pulse. The timing pulses are also fed to a third pulse generator 114 whose output is fed to a speed indicator 30.

As shown, Figs. 4, 6, a laminated timing element comprises a stack of rectangular non-magnetic conductive plates 1, e.g. of Cu or Al, each having an aperture 2 from which extends a tangential slot 3; slots 3 are staggered in alternate plates in the stack. Other laminµ, Figs. 2a, 2b (not shown), possessing capacitive or inductive properties, may be added to the stack, which is held together by conductive studs 10, 11 with conductive spacers 12.

In a collet-chuck for automatic lathes, additional work-clamping jaws 53 for workpieces 81 having headed portions 82 are pivotally connected to an axially displaceable clamping device 50, which co-operates with the collet-locking mechanism. The lathe spindle 25, Fig. 2, contains a collet 38 actuated by a lever 31 which axially moves a sleeve 44 carrying a bevel-closing member 40. In operation, starting from the position of Fig. 2, wherein the lever 31 forces the sleeve 44 to the right, the workpiece 81 is clamped by the jaws 53 and by the collet 38. To release the work, the collet is unlocked by movement of the sleeve 44 to the left, and a sliding head 23 is then moved to the right by a lever 28, and carries with it a rod 56 which, through a spring 65, moves the head 50, jaws 53 and work out of the collet. This continues until nuts 71, carried by a sleeve 55 connected to head 50, engage a stop 75 to prevent further movement of head 50. In this position, jaws 53 are free to swing outwards by centrifugal action, and rod 56 continues to advance, compressing spring 65 to eject the work. This movement of rod 56 is arrested by a stop-collar 68 thereon. Levers 28, 31 are operated by a cam drum 30, Fig. 1, and workpieces 15 are supplied to the chuck from a shoot 16 by a pusher 17 to a receiving member 18 on a turret 12, which is indexed, and are removed after machining by a part 19 on the turret from which they are stripped.
