Filed: 1935-05-10
Abstract: 459,713. Wagon-tipping apparatus. HARRIS, W. A., 145, Brondesbury Park, Willesden Green, London. May 10, 1935, Nos. 13764/35 and 4586/36. [Class 78 (iv)] The wagon is run on to a platform B, Fig. 11, pivotally mounted in one or more frames A supported by rollers C. These frames are rotated by a chain wheel or pinion on a shaft 1, engaging a chain or rack on their peripheries and are simultaneously tilted by rollers E, mounted on a carriage F moving along a track G towards the rollers C. A sustainer beam J, connected by chains S, V to main and auxiliary balance weights N, R, maintains the wagon against its track during tipping. Material spilled during the initial tipping of the wagon is deflected by a plate K to a space formed between the plate and an extension M on the pivoted side chock H. The main balance weight is sectionalized, the amount becoming operative depending on the size of the wagon. In a modification, Fig. 4, the frames are supported on an inclined frame T which may be rotated about its pivot 2 into a horizontal position by a pinion 3, driven from the shaft 1, engaging a rack X. In a further modification, Fig. 8, the chock and platform pivots are adjustable relatively to the frames A, the chock H being mounted on a carriage 4 movable, on rollers along a track Z, and the platform pivot being connected to the frames by a link 6, the relative positions of the pivots being maintained by a lever a. Dust from the tipped contents of the wagon is collected in a hood k<1> suspended from the beam J, and is drawn off through a duct l by a fan. The shaft 1 and carriage F are both actuated through screwed sharts f, f<1> by a hand or motor-driven shaft e<1>, the shaft 1 being driven through worm gearing D<1>, shaft g and spur gearing g<1> from one of the shafts f, f<1>, and detachable screwed parts on a cross-member h on the carriage engaging the shafts f, f<1>.

Title: Di-alkyl substituted alkylene polyamino acetic acids
Inventor: BERSWORTH FREDERICK CHARLES
Filed: 1951-06-11
Abstract: The invention comprises compounds of the general formula <FORM:0727465/IV (b)/1> in which R is an alkyl group containing from 1 to 6 carbon atoms; M is H, NH4, K, Na or amine; n is 0, 1 or 2 and Alkylene is ethylene, propylene, butylene or trimethylene.  They may be prepared by carboxymethylating an alkyl substituted alkylene polyamine of formula <FORM:0727465/IV (b)/2> to replace the remaining amino hydrogens by acetic acid groups, preferably by treating it in alkaline pH solution with alkali metal cyanide and formaldehyde and hydrolysing the product.  With di- and poly-valent metal bases the acids form "chelate" compounds, e.g. <FORM:0727465/IV (b)/3> with calcium hydroxide and a similar compound with ferric hydroxide.  In the examples: (a) N,N1-diethyl ethylene diamine diacetic acid is obtained by carboxymethylating N,N1-dimethyl ethylene diamine with alkali metal cyanide and formaldehyde followed by acidification; (b) N,N1-diethyl ethylene diamine diacetic acid is obtained as in (a) by using N,N1-diethyl ethylene diamine instead of the di-methyl diamine; (c) N,N1-di-isopropyl ethylene diamine diacetic acid is obtained by similarly carboxymethylating didiisopropyl ethylene diamine; (d) N,N1-dihexyl ethylene diamine diacetic acid is obtained by similarly carboxymethylating N,N1 - dihexyl ethylene diamine; and (e) N,N1 - dibutyl ethylene diamine diacetic acid is obtained by treating an alkaline solution of N,N1-dibutyl ethylene diamine with hydrocyanic acid and formaldehyde, followed by acidifying.  Dialkyl derivatives of the following amines may also be used as starting materials: propylene diamine, butylene diamine, trimethylene diamine, diethylene triamine, dipropylene triamine, dibutylene triamine, di-(trimethylene) triamine, triethylene tetramine, tripropylene tetramine, tributylene tetramine and tri-(trimethylene) tetramine. The alkyl groups would replace one hydrogen atom in each of the two terminal amino groups.  Specification 600,629 and U.S.A. Specification 2,387,735 are referred to.

IPC: F41G3/14
Filed: 1921-05-23
Abstract: 189,157. Vickers, Ltd., and Gray, P. W. May 23, 1921. Sights. - Range-keeping instruments, having adjustable arms or bars which when set in accordance with the course and speed of the " enemy " ship and " own " ship will move the adjustable element of the clock in accordance with the rate of change of range of the target, are mounted on the training portion of a director sight or on the gun mounting. Gun training and elevating instructions are transmitted to the gun by the apparatus and the training movement of the sight automatically effects the setting of the instrument to " own " course and speed. Corrections for change of range during flight of projectile and for drift, in addition to spotting corrections, are superimposed on the adjustable members by adjustable gearing. The director sight pedestal A, Fig. 4, carries the range-clock casing B<4> containing the adjustable members O, T. The former is actuated from the fixed wheel A<x> to correspond with " own " course and from the head O<4> in accordance with "own " speed, and the latter is adjusted by the head T<5> for the speed of the target and by the head T<3> for the course of the target. A pin Ox engages slots in members R<2>, D<2>, moved thereby in accordance with the rate of change of range and the rate of change of deflection respectively, due to " own " course and speed and a pin T<x> engages slots in members R<3>, D' for a similar purpose in regard to enemy ship. The member R<2>, Fig. 6, is associated with a pivoted arm R<4> and a member R<5> bv which it mav be moved from the cam R<6> and the handle R<8>. The cam R<6> corrects the range for " own " speed, and spotting or other corrections are superimposed by the handle R<8>. The member R<3> is similarly associated with a pivoted arm R<4x> and a member R<5x> operated from the cam R<6x> and the differential gear R'. The movement of R<5x> is in accordance with the change of range due to speed and course of " own " ship and target during the time of flight of projectile and the cam R<6x> converts the range into time of flight of projectile. The movements of the shaft R<9x> are added to the range movements of the handle R<1> by means of the differential gear R<10> and thence transmitted to the pointer R<11>. In maintaining the pointer R<11> opposite the pointer R<12> the range is transmitted to the gun sights as described in Specification 188,694 by means of the switch R<13>. A somewhat similar arrangement of mechanism to that shown in Fig. 6 is utilized to transmit to the gun the sum of the angle of bearing, the deflection and the drift, representing the total training of the gun.

Abstract: 952,852. Securing wheels to hubs. R. F. HOLBROW. July 24, 1961 [April 25, 1960], No. 14405/60. Addition to 903,281. Heading B7C. The wheel securing arrangement disclosed in the main Specification is modified in that the frictional engagement between the pinion 25 and the friction plate 28 provided by mating plane or conical surfaces (not shown) on the pinion and the plate, is adjustably controlled by means of conical spring washers 36 interposed between the friction plate bars 27 and the retaining bolt 30. The bolt 30 is adjusted to compress the washers to provide the required slip torque. In use, when the pinion 25 is operated to tighten the wheel nut 19, the frictional driving connection between the pinion 25 and the plate 28 is broken only when the turning torque is sufficient to rotate the plate 28 on its left-hand thread to tend to compress the washers 36 still further. In this arrangement positive rotation of the plate 28 may be facilitated by the provision of mating radial teeth 33, 34 on the engaging faces of the pinion 25 and plate 28, respectively.

Title: An improved process of and apparatus for causing solids to be penetrated by or impregnated with liquids or solutions of various substances
IPC: B27K3/10
Filed: 1928-05-16
Abstract: 317,427. Collins, H. J. May 16, 1928. Waterproofing; proofing against bacteria etc.; proofing processes; wood, treating with liquids. -Material to be impregnated with liquid is suspended in the liquid in a container under pressure, and by means of a continuous series of variations of the volume occupied by the liquid, there is produced a continuous series of impulses or variations in the pressure, depending on the compressibility of the liquid and of the! material, and on the elasticity of the container, the change of volume being effected by mechanical displacement of a portion of the liquid. The liquid may be kept under pressure by means of a pump, and the variations of pressure produced by means of a byepass, or by adjusting the pump so that the speed of the delivery stroke is suddenly accelerated as the end of the stroke is reached. The apparatus shown, particularly applicable to treating hides with tan solution, comprises a drum 3 having a filling funnel 4 and a connection 12 to the pressure system. A support 7 for the material treated is, provided, and one side 8 of the drum is removable. The delivery side of a pump 13 of any suitable type is connected to the pipe 12, the inlet side being connected to a tank 14. Between the delivery valve 15 and the drum 3 a byepass 17 is provided, connected to the pump through a cock 20, and to the supply tank 14 through a cock 21. The hides are suspended in the drum 3, and the tan solution put into the tank 14. The pump is operated to fill the drum, the cock 5 at the top of the latter being open. When the drum is full, the cock 5 is closed, and the pressure increased to about 100 lbs. per square inch. The cock 20 in the byepass is then opened, so that variations in the pressure are produced by the action of the pump. In a modification, the liquid in the drum is separated from that in the pump system by a diaphragm, to which the impulses are applied. This method is applicable in the case of corrosive fluids. In place of a diaphragm a cylinder containing a piston may be employed.

Abstract: 345,872. Fishing reels. ALLCOCK & CO., Ltd., S. and COTON, W., Standard Works, Redditch, Worcestershire. May 10, 1930, Nos. 14422 and 29596. [Class 48.] A braking device for the drum of a fishing reel comprises a line-operated lever a, a rotatable cam d, a spring plunger m and a brake l. In the normal position of the cam d, as shown in Fig. 2, the plunger m exerts sufficient pressure on the brake l to produce a slight braking effect. Additional braking effect is obtained by operation of a finger lever j<4>. When the line is pulled the lever a is depressed against the action of a spring g and the consequent rotation of the cam d releases the pressure of the brake pawl d<2> against the edge of the drum. A tooth n is provided which can be moved in a slot to engage a ratchet on the drum. A recess r, Fig. 4, accommodates the mechanism and the axial mounting of the cam d on the drum axle e. The tension of the spring g can be varied by a screw i and block h and in the second Provisional Specification it is stated that the block h is visible to indicate light, medium or heavy power in the spring g.

Abstract: 686,128. Automatic exchange systems. PHILIPS ELECTRICAL INDUSTRIES, Ltd. June 9, 1950 [June 14, 1949], No. 14446/50. Class 40 (iv). [Also in Group XXXVI] A test circuit comprising a valve B with a control grid g, anode a and a second anode s which has a secondary emission factor exceeding unity is used to locate an idle multipled outlet of a selector switch S1 and apply an immediate busy marking by raising the cathode k to earth potential, thereby preventing simultaneous connections. An idle outlet is characterized by a negative potential V1 ( - 60 v.) and since the control grid has a higher potential ( - 30 v.) determined by a potentiometer R4, R5, R6 connected between voltage sources V1, V2, the valve becomes conductive and relay T disconnects the switch drive magnet DM. Due to secondary emission the potential of anode s increases and causes the grid to rise to earth potential with a corresponding effect on the cathode. In a modification, resistors R5, R6 may be substituted by a battery connected between the control grid and anode s. In a further modification, delay in attaining busy earth potential at the cathode due to the inductance of relay T may be avoided by the use of a screen grid having a potential exceeding that of anode s. Alternatively relay T may be replaced by a second valve directly controlling the drive magnet. Specifications 660,376 and 686,075 are referred to.
