Title: Improvements in oil-fired water heaters
IPC: F23N1/02
Filed: 1932-11-08
Abstract: 395,226. Diaphragm pumps. HEIMBOLD, A., Auerbach, Erzgeburge, and KRAUSE, K., Rabenstein, Saxony, both in Germany. Nov. 8, 1932, No. 31496. Convention date, Nov. 12, 1931. [Class 8 (i).] A water heater is heated by a spray burner in which the oil fuel is atomized by compressed air supplied by a pump operated by the water flowing under pressure to the heating coil. The pump contains a rubber diaphragm 3 which is raised by the water supplied through a connection 2b to force the air above the diaphragm past a valve 4 to the burner. When the diaphragm reaches the top of the pump chamber the increased pressure below the diaphragm opens a valve 8 to permit a diaphragm 10 to be operated by the water pressure to open a valve 11 allowing water to pass to the heating coil. The fall of pressure closes the valve 8. The diaphragm then descends under the influence of a spring 13 air being drawn past a valve 35 into the upper part of the pump chamber. At the end of its downward movement the diaphragm 3 opens the valve 8 and relieves the pressure on the diaphragm 10 so that the valve 11 closes and the cycle is repeated. The pulsations in the air and water supplies are reduced by the interposition of reservoirs 7 in the pipe lines.

Abstract: 831,621. Holders for thermionic valves. UNITED-CARR FASTENER CORPORATION. Oct. 10, 1957 [Dec. 31, 1956], No. 31752/57. Class 38 (1). A socket member 10 for the reception of the projecting terminal pins of a valve or the like is equipped with a number of terminals 11. About a central opening 13, which is adapted to accommodate an earth terminal, are situated a plurality of terminal-receiving openings 14, and an annular channel 16 has a number of pin-receiving apertures 17 for the valve. In assembling a terminal 11 with the socket 10, spring fingers 29, 30 are moved inwardly by inclined edges of frame 20, so that, as the terminal is moved downwardly, the fingers rub along the outer walls of the opening 14 and ultimately align with recesses 24, 25, so as to engage shoulders 38, 39. At the same time, wall portions of the intermediate sections 33, 34 of the terminal abut a shoulder 40 to prevent further downward movement. The lower edges of contact-receiving members 27, 28 engage the upper surface of abutment member 19, and further constrain downward movement. Thus, the terminals are locked within the openings. Further, ribs 21 are received between the fingers 29, 30, when the terminals are inserted into the openings to ensure that the fingers will seat within the recesses 24, 25. The tail members 26 of the terminals are curved in section for stiffening purposes, and central sections 31, 32 are bowed inwardly so as to provide good contact with a valve pin.

Abstract: 1,215,668. Making race rings by coiling metal wire. TRW Inc. 24 June, 1969, No. 31932/69. Headings B3A and B3E. [Also in Division F2] A ball bearing cage 14, Fig. 2, is formed of a flexible filament which is wound to produce an annulus of circumferentially spaced annular pocket-forming rings 17, having radiallyspaced inner and outer peripheral ends and being connected together by portions 18. In an embodiment a cage 14, having an odd number of rings 17, is formed on a fixture 20, Fig. 3, having a cylindrical member 21 with the same odd number of equally-spaced radial holes 22 therein, each of which receives a cylindrical stem 24 of a winding-head 23 therein. Each of the latter has also a cylindrical periphery the size of which coincides with the size of a pocket 19 to be formed within the ring 17, and has a tapered portion 26 which produces a lip 19a, Fig. 2, to prevent balls dropping inwardly therethrough. A single filament strand 27, Fig. 4, is wound around the heads 23, and, because the number of rings 17 is odd, the strand 27 automatically alternates over and under the winding heads 23. When the number of rings 17 is even, filament strands 28, 29, Fig. 5, are necessary to form the rings. The cross-over portions 18 may be lock-stitched together. In another embodiment a filament 30, Fig. 6, makes one full turn about a winding head 23 before passing to the next head 23. Other embodiments describe the making of a cage by means of a filament or filaments being wound about winding heads. The cage may be formed in situ in a bearing by using a fixture 34, Fig. 9, which locates balls 40, Fig. 11, while the winding of the filament or filaments is effected. The filaments may be fibre-glass or metal wire for example and may be bonded respectively by a thermo-set plastics material or by heat.
