Filed: 1919-07-08
Abstract: 147,344. Petersen, V. S. K. July 8, 1919. Addition to 104,184. Heat and temperature coefficients, apparatus for determining.-In apparatus of the kind described in the parent Specification, the heating-medium is passed through a by-pass pipe 2 which is in heatexchanging relationship with a pipe 3 conveying a cold fluid. The hot and cold junctions of the thermopile 1 are respectively acted upon by the pipes 2, 3 so that, if the hot and cold fluids flow in the same direction, the temperatures of the hot junctions will progressively diminish and those of the cold junctions will progressively increase. An indication is thus obtained depending on both the velocity and the temperature of the fluid in the pipe 2. The elements of the thermopile may themselves serve to convey heat from the pipe 2 to the pipe 3.

Filed: 1937-06-21
Abstract: 496,296. Reducing - valves. WHITEHEAD TORPEDO CO., Ltd., and JONES, L. June 21, 1937, No. 17293. [Class 135] In a pressure-reducing valve the pressure to be reduced acts on a diaphragm and is opposed by a controllablefluid pressure acting on the opposite side of the diaphragm and supplied by way of a sensitive pilot reducing-valve whose function is to control the pressure of the fluid passing through the main valve. The fluid under pressure passes from an inlet 12, Fig. 1, to an outlet 8 when a ball valve 6 is raised by a plunger 9 operatively connected to a diaphragm 4 the underside of which is exposed to the pressure of a spring 15 in an airtight casing 14 and fluid pressure communicated through an inlet 41 connected to the outlet of a pilot valve, Fig. 3. The pilot valve is of similar construction to the valve shown in Fig. 1, but the loading of the spring 15 is adjustable by an arm 22 movable in slots in the spring casing 14 under pressure of oil admitted to the underside of a piston 28 engaging the arm 22, the movement being limited by stops 34a of different heights on a rotatable sleeve 31 surrounding the casing 14. The fluid from the outlet 8, Fig. 1, passes to the inlet of a second reducing-valve similar to that of Fig. 1, but without the spring 15, the diaphragm being controlled solely by the pressure from the pilot valve. The diaphragms are supported by ribs or spiders 19a. In a modified form of valve, the diaphragm 4, Fig. 4, is of synthetic rubber and canvas or of other very flexible material and is supported by pivoted spokes 35. An alternative system of arranging the valves consists of two small valves constructed according to Figs. 1 and 3, and acting as first and second stage pilot reducing valves and two main reducing-valves in series constructed like the valve of Fig. 1, but without the spring 15. Specification 496,297 is referred to.

Title: Improvements in or relating to a method of and machine for lapping a surface of revolution on a workpiece
IPC: B24B5/04
Filed: 1936-06-30
Abstract: 473,784. Lapping surfaces of revolution. SHEFFIELD GAUGE CORPORATION. June 30, 1936, No. 18153. Convention date, July 5, 1935. [Class 60] In the lapping of a surface of revolution on a workpiece, the work is rotated on its axis by engagement with a flat rotating lapping- face, and is moved across the lapping-face whereby the rotation of the lapping-face, which is driven frictionally, is changed indeterminately. The lap 14 is carried by a head 13 mounted on a bed 10, and is supported and frictionally driven by a sleeve 37 mounted on a bolt 30, which has a head 29 adjustable in a transverse T-slot 28 in a flange 25 on a driving spindle 21 rotatable in the head 13, the bolt and sleeve being secured in position, with the lap at any desired eccentricity, by a nut 40<1>. The work is supported by a head 16 comprising a transversely movable slide 41, carried by ways 40 on the bed 10 and supporting a block 44, angularly adjustable by screws 48 in slots 49. The block has ways thereon for a carriage 46 movable by a screw 51 and provided with a projection 55 in which is an opening 56 receiving a stud 57 projecting from a yoke 58. Pointed screws 61 in the arms of the yoke serve as a pivotal mounting for a work carrying frame comprising a bar 65 having guide faces 66 to support adjustable holders 67, each of which carries a work centre 72, the holders being locked in adjusted position on the bar 65 by members 76 engaging a T-slot 73 in the bar and operated by cam ends 81 of shafts 77 actuated by arms 79. One centre 72 is spring mounted in its holder 67 and is movable by a turnable finger-piece 85, a screw 88 serving to lock the centre in the desired position so that the work 100 is free to be rotated by its contact with the lap ; the pivotal mounting of the bar 65 allows the work to adjust itself to the lap face, the bar being prevented from rocking too freely by the contact therewith of spring-pressed balls 110 mounted in the yoke arms. The work is moved across the lapping-face by movement of the slide 41 by a link 97, which is moved by an arm 94 rocked by a shaft 90 carrying a hand actuating lever 91. In operation, the lap is rotated, at desired eccentricity, by the spindle 21 and drives the work, which also is reciprocated across the lap by the lever 91, this movement causing the lap to slip indeterminately on the sleeve 37, so that all parts of the lapping face come into operation and uniform wear of the face is ensured. For lapping longer work, an auxiliary lap of larger diameter is held on the face of the lap 14 by a central screw engaging in the bolt 30. In order to cause the lap to slip on the sleeve 37, for example, when the work is small and its friction does not cause slipping, a brake 108, adjustable by a screw 106, is mounted in an arm 105 so as to engage the periphery of the lap.
