Title: Improvements in and relating to grinding and disintegrating machines
IPC: B02C18/30
Filed: 1923-02-15
Abstract: 205,422. Joly, A., and Clark & Co., Ltd., R. I. Feb. 15, 1923. Disc and like mills.-Relates to grinding and disintegrating machines for paints, gums, pigments, &c. and of the kind in which the material is subjected to shearing actions in a chamber by a plurality of sets of grinding-elements comprising relatively stationary and relatively movable elements. The machine has a working chamber containing a plurality of sets of grinding-elements arranged so that an annular chamber is formed between adjacent sets, some of the elements being perforated whereby the material is disintegrated into colloidal particles capable of giving colloidal solutions. As shown, the machine comprises a working or grinding chamber a containing a series of movable grinding-elements b mounted on a rotatable shaft d and a series of stationary grinding-elements c. The elements b are in the form of perforated discs clamped to the shaft d by means of distance-pieces f and nuts g on the end of the shaft. Or the shaft d may be of polygonal cross-section and the elements b formed with correspondingly shaped apertures to engage the shaft. The stationary elements c are also in the form of discs held in position by distance-pieces h; some of the elements c are plain and others j are provided with apertures. The grinding-elements are arranged in sets, each set comprising a perforated upper stationary disc, a plain lower stationary disc, with a rotating disc between them. By moving the distance-pieces h towards or from the shaft d the size of the annular chamber k formed between two sets of elements can be varied. A movable disc l is located at the outlet of the chamber a and the material discharged through the outlet passes into a discharge chamber m having an outlet n. The inlet chamber o is formed in the housing p. The shaft d is mounted in ball bearings q and covers r are provided at each end of the shaft. A micrometer device w is provided for adjusting the shaft d and regulating the distance between the fixed and movable discs. In a modification, the inlet chamber is located at the end of the shaft and a stationary apertured disc is arranged at the entrance to the grinding-chamber.

Title: Internal combustion engine having a throttle valve control mechanism
IPC: F02D35/00
Filed: 1976-02-05
Abstract: 1514098 Control of carburetter throttle valves NISSAN MOTOR CO Ltd 5 Feb 1976 [10 Feb 1975] 04614/76 Headings F1B and F1H A carburetter for an I.C. engine is electronically controlled in use in response to the composition of exhaust gases from the engine entering a three way catalytic converter and includes a throttle valve 24, with which one or both of mechanisms 44 and 46 co-operate to prevent or relieve vacuum downstream thereof during deceleration. When the throttle valve 24 is closed, a projection 32 on a lever 30 rigid with the throttle valve engages an arm 42 whose leftward movement as shown in Fig. 1 is damped by a dashpot mechanism 44 having an orifice 62 in parallel with a check-valve 66. If the vacuum downstream of the throttle valve 24 exceeds a predetermined value, a diaphragm 96 opens a valve 101 so that vacuum acts by way of a diaphragm 72 to move the arm 42 to the right and thereby slightly open the throttle valve 24. Subsequent opening of the throttle valve 24 by the engine operator causes a fall in the vacuum downstream thereof so that valve 101 closes and the pressure acting on diaphragm 72 is increased to atmospheric by means of air-flow through a passage 106, thus returning arm 42 to its normal operating position. The exhaust gas condition is sensed, e.g. by an oxygen sensor 40, upstream of three-way catalytic converter 38 and a signal is fed to a computing means 34 which issues signals to a valve means 33 to control the fuel flow-rate to the carburetter to ensure that it delivers a stoichiometric mixture.

Title: Control mechanism for water-heating systems
IPC: F24D19/08
Filed: 1927-02-19
Abstract: 275,501. Griffiths, W. J. Feb. 19,1927. Heating buildings.-A control valve for a water heating system comprises a hollow body 1 divided by partitions 2, 3 into three compartments 4, 5, 6. A water inlet 7 communicates with the compartment 4 and a spring pressed non-return valve 11 is interposed between the compartments 4 and 5. An opening communicates with the heating system and a second non-return valve 15 separates the exhaust port 9 from the compartment 5. Between the compartments 4 and 5 a manually operated valve 19 is fitted to enable direct communication to be established at will. The tension on the springs 12, 16 can be adjusted by adjusting the position of the members 13, 17. In operation, assuming the system to be empty, the water forces the valve 11 from its seat and enters, and the pressure within the system can be adjusted by varying the tension in the spring 12. Excess pressure within the system is relieved by the valve 15 which opens at any predetermined pressure. If the pressure is maintained and the water is low, fresh water is admitted through the valve 19. A pressure gauge 22 indicates the pressure in the system. Bridges 26, 28 are provided for centering the valve guides 25, 27.

Title: Improvements in or relating to the measurement of resistance to lateral displacementof soils
IPC: E02D1/02
Filed: 1940-03-13
Abstract: 540,527. Testing soil resistance to displacement. PIMM, G. B. R. March 13, 1940, No. 4754. [Class 106 (ii)] In forming foundations for structures the resistance of the soil to lateral displacement is tested by measuring the resistance to driving of two test piles, one being parallel or of constant diameter and the other of taper form, having its lower diameter equal to that of the first. In a modification, two piles of different tapers are used in conjunction with the parallel pile. The parallel pile, Fig. 1, may comprise an outer tube and an inner mandrel with a shoulder at the lower end of the same diameter as the outside of the tube. The forces opposing driving comprise a direct resistance 3 acting on the lower end, and the frictional resistance 7, the earth pressure 4 having no vertical component. The resistance 3 is measured by first driving the mandrel, and the frictional resistance 7 by then driving the outer tube. In the case of the tapered pile, Fig. 2, the resistance to driving comprises the end resistance 3, the frictional resistance 8, which is greater than 7 on account of the tapered form of the pile, and the vertical component of the resistance 5 due to the displacement of the ground. The frictional resistance 8 may be calculated with sufficient accuracy from the measured resistance 7 of the parallel pile, and hence the resistance 5 found. Alternatively, the frictional resistances 7 and 8 may be found by measuring the torque necessary to rotate the piles after driving. When two tapered piles are used, blows of the same energy are used to drive all three piles, and the sets are measured. From the facts that the energy expended in each case on overcoming the 'friction is proportional to the set, the energy expended in displacement of the soil in the case of the two tapered piles is proportional to the volumetric displacements, whilst the common end resistance 3 of the piles is known, the displacement resistance may be calculated.

Abstract: 1,221,731. Cross-linked copolymers of ethylene oxide and epihalohydrins. HERCULES Inc. 28 Jan., 1969 [29 Jan., 1968], No. 4778/69. Heading C3R. [Also in Divisions B2 and D1] Copolymers of ethylene oxide and 10-90% of at least one epihalohydrin, having a molecular weight of at least 30,000, are cross-linked on non-woven fibrous material (see Divisions B2 and D1). The cross-linking agent may be a polyamine or salt thereof; a heterocyclic compound selected from 2-mercapto-imidazolines, thiazoline - 2 - thiones and 2 - mercaptopyrimidines in combination with a metal salt of a carboxylic, carbonic, phosphorous or silicic acid or an oxide of a Group IIA IIB or IVA metal; urea, thiourea, ammonia or ammonium salt. The copolymers generally contain an antioxidant, added during polymerization. The polymers may be mixed with fillers, e.g. carbon black, silica, clay, asbestos and mica. When using a finely divided silica filler, a reactive silane is also preferably added. The polymers are applied in solution and cured by heat. This may be effected in two stages with an intervening step of coagulating the polymer by immersing in a non-solvent.
