Title: Improvements in sheet feeding mechanism
IPC: B65H1/22
Filed: 1927-07-05
Abstract: 275,193. Spiess, G. July 28, 1926, [Convention date]. Sheet-separators; pile supports. - In mechanism for feeding sheets from a fanned out pile in which the sheets are separated and fed forward by a rising and falling combing-wheel 5, Fig. 1, which is raised automatically by mechanism controlling the motion of a shaft 26 when the separated sheet reaches a feeler device, the motion of the wheel 3 for advancing the pile is controlled directly by the sheet-feeding device, by means of a guard 16, Fig. 4, which is connected by a spring 19 to a lever 20 connected by linkage 21, 22, 24 to a lever 25 on the shaft 26. The guard 16 acts on a pin 17 on a pawl 10 operated by a lever 9, connecting-rod 13, and an adjustable crank 14 on a shaft 15 which makes one revolution for each sheet fed. The guard 16 either prevents engagement of the pawl 10 with a ratchet 8, or permits the pawl to engage the ratchet 8 for a whole or part of the movement of lever 9, the extent of engagement depending on the time that the wheel 5 is in action. If this wheel is raised quickly on account of the forward position of sheets in the pile, the ratchet is not operated on. If, however, the pile needs advancing, the pawl 10 engages the ratchet before the guard 16 is rotated to prevent the engagement. The shaft of ratchet 8 is geared to the wheel 3 and to a conveyer 28 which assists to advance the pile.

Title: Improvements in articles for contacting molten glass
IPC: C03B5/08
Filed: 1937-06-28
Abstract: 496,412. Metal articles for use with molten glass. NAAMLOOZE VENNOOTSCHAP MAATSCHAPPIJ TOT BEHEER EN EXPLOITATIE VAN OCTROOIEN. June 28, 1937, No. 17934. Convention date, June 27, 1936. [Class 56] [Also in Group II] Parts, such as the delivery nozzle lining shown in Fig. 2, intended for contact with molten glass, comprise a body 12 of platinum with an integral rhodium or rhodium-containing coating 13 on the surface not in contact with the glass ; volatilization of the platinum, which does not occur appreciably at the surface covered by the glass, is thereby prevented also at the surfaces exposed to air, or in contact with refractory material 10. The coating may consist of rhodium applied by electrodeposition. The article may be subsequently heated to 1400 or 1500 degrees Centigrade so that the metals diffuse and form an alloy at the interface. Alternatively, a platinum-rhodium alloy coating may be applied by rolling, drawing, or swaging an ingot of the alloy to the desired form, nesting it with a similarly-formed platinum body, and heating them to welding- point. Glass-contacting articles, such as the crucible shown in Fig. 3, which are intermittently exposed to the air whilst at high temperature, are similarly coated on all surfaces of the platinum body 14 with a rhodium or rhodium-containing casing 15.

Title: Improvements in means for supplying air to charge-forming devices for internal combustion engines
IPC: F02M1/00
Filed: 1943-11-01
Abstract: 572,246. Charge-forming apparatus. BENDIX AVIATION CORPORATION. Nov. 1, 1943, No. 18064. Convention date, Nov. 23, 1942. [Class 7 (iii)] An island baffle in a turn or elbow in an air intake conduit divides the turn into two passages in parallel, of which the outer one is of increasing cross-sectional area and the inner one of decreasing area. The outer passage may turn through an angle of more than 90 degrees. The walls of the island diverge from the leading edge to the turn and thereafter converge to the trailing edge. The air stream entering by a scoop 212 is divided by a baffle 236 into two streams, the outer one of which one is accelerated by traversing a venturishaped passage 241 and then slowed down by the increasing cross-section of the passage, while the inner one is accelerated by its passage through a tapering channel between the baffle and the inside wall of the bend of the inlet passage, the streams re-uniting at 214 before entering a carburetter 204. As shown, the scoop 212 admits cold air which passes a butterfly valve 246 resiliently connected to a control arm 270 having on its outer end a cam follower 272. The follower engages in a cam groove 320 concentric and rigid with an operating pulley 324 and a rotary valve 225 rotatable between webs 344, 346 and 348 which define an entrance to the air inlet passage, shown in the closed position, an entrance 340 for warm air drawn from within the engine cowling and one 342 for hot air from a jacket surrounding the exhaust manifold. Clockwise rotation of the pulley 324 rotates the cam 320 to close the cold-air inlet valve 246, the resilient connection of the arm 270 permitting the valve to remain slightly open if ice should prevent its complete closure, and the cam follower 272 then rides along a circular part 333 of the cam until the valve 225 has moved round far enough to close the hot air inlet 342. Further movement first admits both hot and warm air, the inlets 340 and 342 being both partly uncovered ; at this point, the cam follower 272 reaches an offset portion 338 of the cam 320 and the increased stress put thereby on the resilient connection of the arm 270 indicates to the operator that this position has been reached. Further movement of the valve 225 closes the warm-air inlet and only hot air is supplied to the chargeforming device 204. Specification 523,895 is referred to.

Abstract: <PICT:1118648/C1/1> <PICT:1118648/C1/2> To produce an array of light pipes in which the diameter at one end of each pipe is smaller than at the other end, a plurality of nonparallel beams of light equal in number to the required number of light pipes, are passed through a block of photo-sensitive glass, sensitive to the wavelength of the light and positioned such that the beams of light have the required diameters on entering and leaving the block of glass, the block of glass is treated to develop the portions exposed to the beams of light and the developed portions etched out of the block, the remainder of the block then being treated to render light reflective the walls of the pipes so produced.  As shown, a block 8 of glass is positioned in front of a source 1 of ultra-violet light with the interposition of lens 2 and 3 and a mask 5 with apertures 6 corresponding to the desired pipes. The apertures 6 may be arranged as shown to give central pattern of pipes, as in Fig. 3, or may be to one side of the mask 5 so that the light pipes are concentrated to one side of the block 8.  The beamed portions are heat treated to develop them and then etched by hydrofluoric acid.  To render the pipes light reflective, the glass may be further heat treated to turn the glass into a white glass-ceramic, or alternative methods may be used, such as silvering.  To exclude dust, the light pipes may be filled with a transparent material.
