Abstract: 100,200. National Malleable Castings Co., (Assignees of Bixby, A. S.). March 20, 1915, [Convention date]. Driving-chains with separate joint pins. -In chains wherein the pins have distinct articulating surfaces and pull-transmitting surfaces to minimize lengthening of the chain due to wear, the articulating surfaces have relative movement while in contact with one another during articulation. In the construction shown in Fig. 4, pulling- stresses are transmitted from the link 3 to the pin B of the link 4 along the line a b; but when the chain bends, the pins rock about a point c, and wear is limited to a line b e. The line a b may be straight or curved, and the pin B may be composed of two superposed members C, D, Fig. 7, the upper of which is round, and the lower one of either round or square section. Projections 12, Fig. 6, on the links are bent into grooves 13 in the pins to secure them.

Title: Improvements in Water Softening and Purifying Apparatus.
Inventor: PATERSON WILLIAM
IPC: C02F1/52
Filed: 1916-03-22
Abstract: 104,919. Paterson, W. March 22, 1916. Purifying liquids.-In water-softening and purifying apparatus, the reagent measuring gear c, d is enclosed within a closed container b under air or gas pressure, which is utilized to discharge the treated water from the treating-tank a to the storage tank f or other situation. A ball cock k closes the delivery pipe e to the tank f before sufficient water has passed to unseal its lower end. According to one arrangement, a ball cock m controls the flow of water to the tank f, and when this cock is closed, the increasing gas pressure in the tank a due to inflowing water acts upon a diaphragm n to close a valve h in the water-supply pipe g. According to another arrangement, the valve m is omitted and the supply pipe g is controlled directly by a float in the tank f. To maintain pressure in the tank a, air may be injected with the water. The reagent tank p has an inlet valve q, which is closed before a valve r is opened to pass reagent to the container b ; or reagent under pressure may be supplied by a ball cock. Specification 28179/11 is referred to.

Abstract: 416,574. Gramophone pick - ups. ELECTRIC & MUSICAL INDUSTRIES, Ltd., Blyth Road, Hayes, Middlesex, and WHITE, J., 26, Connaught Gardens, Palmers Green, London. Feb. 13, 1933, No. 4433. [Class 40 (iv).] An electromagnetic vibratory device, more particularly a gramophone pick-up, comprises an acoustic current coil associated with a magnetic circuit, an auxiliary coil arranged close to the acoustic current coil but so as to link with substantially none of the varying flux set up in the neighbourhood of the acoustic current coil when, in operation, acoustic frequency current flows therein, and a pair of terminals, the auxiliary coil being of such a nature, and the two coils being so connected together and to said terminals that, when said device is disposed in a fluctuating external magnetic field, such as that due to a talking machine motor, substantially no potential difference due to said field is set up between said terminals. The Figure shows a pivoted armature gramophone pick-up having an auxiliary coil 10 mounted on a base plate 9 below the yoke of the permanent magnet 1. The coil 10 has the same physical dimensions as the acoustic current coil 7 with which it is connected in series with respect to two leads 11 which are connected to the output terminals of the pick-up. The coils may, however be connected in parallel with respect to the output terminals. The coil 10 may be slightly tilted with respect to the base 9 so that both coils 7, 10 may lie more nearly in the same mean horizontal plane and the coil 10 may also be provided with a magnetic core in order to balance its inductance with that of coil 7. According to a modified construction, the coil 10 is mounted between the poles of the magnet 1 so as to lie upon the polepieces and to be coaxial with coil 7. In this case, the inductance of coil 10 may be made greater than that of coil 7.

Filed: 1934-02-12
Abstract: Current-collectors for traction purposes such as trolley wheels are made from a known aluminium bronze containing a small proportion of manganese and/or nickel having a refined structure produced by heat treatment and/or working.  The heat treatment may comprise a normalizing at 400 DEG  C. for 21 hours following a quenching from 850 DEG  C.  The collectors may be produced by casting a blank of the alloy, forging at 800-900 DEG  C., quenching and then heating at 400-450 DEG  C.  If it is not possible to quench the forging, the latter may be heated to 850 DEG  C. quenched and then reheated at 400-500 DEG  C.  In an example the alloy contains 9-11 per cent of aluminium and 0,2-3,0 of manganese with or without 0,2-5,0 of nickel but not more than 5 per cent of manganese and nickel combined.

Abstract: 739,937. Brick-laying. SLAGTER, C. Feb. 19, 1954 [Feb. 21, 1953], No. 4942/54. Class 20 (4). A method of laying bricks to form a wall comprises arranging them between two bordering members 8, 9 defining the faces of the wall to be erected and mounted for vertical stepwise movement as the building of the wall proceeds, and applying a quantity of mortar in vibrating condition upon each course of bricks. As shown, a finished course of bricks 3 previously embedded in mortar, and a course of bricks 2 to which vibrating mortar is to be applied, lie within the space defined by the members 8, 9 which are suspended from a supporting construction, not shown, and provide runways for the rollers 11, 12 of a frame 15 which supports a mortar hopper 16. The lower cylindrical portion 19 of the hopper, reaching into the space between the members 8, 9 is provided adjacent its upper end with outwardly projecting abutments 23, 24 which bear indirectly upon the frame 15 and support the hopper 16 therein, resilient means 25, 26 being interposed between the abutments 23, 24 and the frame 15. A handle 20 is provided at each side for removing the hopper from, and replacing it in, the frame 15. A high-frequency electric vibrator 30 is mounted on a removable bridge 27 having slotted legs 28, 29 which resiliently engage the upper edges of the side walls 17, 18 of the hopper, the vibrations of the vibrator being transmitted through the resistor to the underlying bricks in the course 2 and also through the side walls 17; 18 to the members 8, 9, the amount of vibration transmitted to the members 8, 9 being controlled by the choice of resilient members 25, 26. The hopper has an adjustable bottom sliding lid 37 guided in grooves 38, 39 in the side walls of the cylindrical portion 19, the spreading of the vibrating mortar upon the bricks in the course 2 being regulated by opening the lid 37. The underlying bricks are then temporarily vibrated, the vibration of the members 8, 9 pentrating nearly as far as the course 4. The hopper is gradually moved along the members 8, 9 while the bricks for the succeeding course are placed on the freshly laid mortar behind the hopper. The hopper may be divided by partitions, and the abutments 23, 24 may be replaced by a continuous ledge.
