Title: An improved process for cutting bundles of continuous artificial filaments into staple lengths
IPC: D01G1/04
Filed: 1938-11-08
Abstract: 507,289. Stapling continuous filaments. VEREINIGTE GLANZSTOFF FABRIKEN AKT.-GES. Nov. 8, 1938, No. 32349. Convention date, Nov. 15, 1937. [Class 120 (iii)] In cutting bundles of continuous artificial silk filaments into staple lengths continuously with their production from a spinning machine by leading the bundle through a radial passage 6 in a rotating wheel 3 and cutting the filaments by stationary knives 5 disposed at the peri. phery of the wheel, compressed air is forced through the passage in the direction of the entering bundle; the air reduces the friction of the bundle in the passage and so causes an increase in the centrifugal force acting on the bundle. As shown an air supply conduit 8 is cast in the wall of the funnel 7 leading to the passage 6 in the rotating wheel 3, and a supply tube 9 and an exchangeable nozzle 10 are connected to the conduit 8. Specification 289,028, [Class 120 (iii)], is referred to.

Abstract: 678,727. Converting rotary into reciprocatory motion. PEGSON, Ltd. Dec. 6, 1950 [Dec. 16, 1949], No. 32349/49. Class 80 (i). [Also in Group V] A machine for moulding tiles (see Group V) includes a carriage 23 on which is mounted an electric motor 24 which reciprocates the carriage. The carriage runs on wheels 29 between guides 30 on the machine frame. The motor drives a countershaft 32 via gearing 27, 26, 25, shaft 20 and gearing 33, 34. This countershaft drives, through gearing 37, a third shaft 38 mounted in tubular bearings 39 carried by plates 40 journalled on shaft 32. Shaft 38 carries at each end pinions 41 which co-act with endless racks 42. As shaft 38 rotates, pinions 41 travel counterclockwise in the direction of the arrows, Fig, 3, first in engagement with the upper runs of the racks and then in engagement with the lower runs of the racks, whereby the carriage is traversed to and fro. Shaft 38 carries guide rollers 38a which co-act with fixed guide plates 42'.

Title: Improvements in or relating to water-tube steam generators
IPC: F22B37/22
Filed: 1936-11-26
Abstract: 466,698. Water-tube steam boilers. INTERNATIONAL COMBUSTION, Ltd. Nov. 26, 1936, No. 32406. Convention date, Nov. 27, 1935. [Class 123 (ii)] In water-tube boilers having an intermediate drum 4, connected with a lower drum 3 through uprisers, e.g. furnace wall screen tubes 2, and shortcircuit return tubes 7, and with a steam collecting drum 6 through tubes 5 connecting the upper parts of both drums 4, 6, the tubes 5 are so dimensioned as to provide a restricted passage such that at a predetermined load steam only is forced through the tubes. Feedwater is introduced at a level above the'intermediate drum. A few of the steam upriser tubes may open close to the top of the intermediate drum and others depend further ; the inlets to the tubes may have stoppers or chokes leaving only a small opening or may have a float valve closure controlling the height of the water level in the drum. The openings may be arranged at different levels so that the water level may fall evenly. To prevent overheating the valved tubes may have a small steam opening located close to the top of the drum.

Title: Inking arrangements for rotary printing press
IPC: B41F31/06
Filed: 1958-10-10
Abstract: 869,803. Inking-apparatus. MJEHLE-GOSS-DEXTER Inc. Oct. 10, 1958 [Oct. 10, 1957], No. 32411/58. Class 100(2) A rotary printing press comprises a forme inking roller in rolling contact with the printing plates and means for removing residual ink from the forme roller after an inking impression has been made between the latter and the plates, so that the forme roller is substantially free of ink prior to the feeding of ink thereto by the ink feeding device. Ink in a quantity adjustable by a blade 25, Fig. 1, is taken from a fountain roller 23 by a feed roller 24 in the form of a multi-sided polygon having flat areas defining axially extending ridges and rotating faster than the fountain roller. The roller 24 passes the ink to a forme roller 30. A series of axially reciprocating rider rollers 41-45 distribute the ink before transfer to the plate cylinder 11. Surplus ink is removed by a second series of rider rollers 31-35, the rollers 33, 34 being provided with scraper assemblies 51, 52 and surplus ink returning through a pan 71 to the trough 22. The rollers 43, 44 are provided with similar assemblies 53, 54. When the assemblies 51, 52 are operative, assemblies 53, 54 are inoperative, Fig. 4. By means of a hand-lever 94, the assemblies 53, 54 are rendered operative and the assemblies 51, 52 inoperative, for reverse rotation of the cylinder 11. Each assembly comprises a body 60, Fig. 2, mounted on stub shafts 61, and a clamping plate 62 secured thereto by cap screws 63, securing a blade 64 of tough plastic such as nylon backed by a spring steel blade 65. Set screws 66 on tightening tilt the plate 62 for secure clamping. The forme roller 30, Fig. 3, comprises layers of paper packing 84, a thin metal backing plate 82 anchored to the roller body by pins 83, and a replaceable resilient covering 80 of synthetic rubber. A gap 81 in the roller 30 invariably coincides with a gap between the plates 11a, 11b on the cylinder 11, the diameter of the roller 30 being the same as that of the cylinder 11 with the plates. All the rollers 31-35, 41-45 are axially reciprocated by pulleys such as 42a, 33a, Fig. 5, on their shafts engaged by a common wobble plate 101 on the shaft 100 of the roller 30 or separately mounted and driven. Each pulley may be in two parts spring-urged together.

The slider is resiliently deformable transversely in relation to the direction of movement of the slider so as to enable the abutment surface to be moved past the stop surface during assembly of the device. As shown, the slider has a slot 15 on one side of a bore 11 housing the spring 9 and abutment and stop surfaces are povided by projections 17 in the structure 3 and barblike portions 16 on the slider; alternatively, the projections are replaced by recesses in the structure. An extension 18 has a recess 19 for reception of a tool to draw the slider to a release position.

Filed: 1922-12-01
Abstract: 202,262. Western Electric Co., Ltd., (Assignees of Scriven, E. 0.). Aug. 8, 1922, [Convention date]. Transformers.-A transformer 16, particularly intended for use in a thermionic-valve amplifying set, is provided with a short-circuited tertiary winding 26, the resistance of which is so related to the voltage induced in it as to be the equivalent of a large resistance connected across one of the main windings of the transformer. The transformer is designed with a leakage inductance which resonates with the valve capacity at a frequency near the upper limit of the speech range, the short-circuited tertiary winding serving to damp this resonance. The tertiary winding may be short-circuited on itself, as shown, or through a low resistance, and its potential may be established by a connection to the secondary winding. In a modification, a few turns of the secondary itself are short-circuited, instead of employing a separate winding.
