Title: Improvement in rib fabric, method of and mechanism for knitting the same
IPC: D04B9/06
Filed: 1933-01-21
Abstract: 395,958. Knitting. HEMPHILL CO., Central Falls, Rhode Island, U.S.A.-(Assignees of Lawson, R. H. ; 55, Cooke Street, and Smith, W. L. ; 43, Benjamin Street, both in Pawtucket, Rhode Island, U.S.A.) Jan. 21, 1933. No. 2035. Convention date, Feb. 3, 1932. [Class 74 (ii).] Rib fabric having imitation drop stitches is formed by arranging and controlling the needles in the dial and cylinder of a circular machine so that some of the needles in one bed draw longer loops than the remainder. The longer loops extend through a number of immediately adjacent courses in the same wale or wales. When knitting plated work with two yarns, the loose stitches show as reversely plated areas although there is no actual reverse plating. In one form, each of a number of dial needles 25, Fig. 8, is provided with an edge 26 raised relatively to the yarn-drawing edge of the other dial needles, so that the adjacent cylinder needles draw longer loops. The dial needles 25- may thereafter be caused to draw elongated loops by robbing from these adajcent cylinder needles which have drawn the longer loops. The edge 26 may be raised by bending upwardly the hook end of the needle 25. This bending. brings the hook end nearer to the butt and serves to draw a longer loop for the dial needle. A shorter latched needle also serves this purpose. Alternatively, jacks may be provided beneath the dial needles so that selected needles may be raised for the cylinder needles to draw longer loops. An additional butt may be provided upon the cylinder needles on one or both sides of the dial needles having raised yarn-drawing edges for engagement with a lowering cam which imparts a longer loopdrawing movement to the needles. A dial bed having needle tricks with inclined portions 85, Fig. 25, may be provided, and the needles may have a series of patterning butts 91 for depression by cams 93 so that the hook ends of the needles are raised. Other cams 98 act subsequently to depress further the butt ends of the needles so that the dial needles rob the adjacent cylinder needles of the excess yarn they have drawn.

Title: Apparatus for measuring the quality and quantity of x-radiation
IPC: G01T1/16
Filed: 1941-02-17
Abstract: 546,095. Measuring quality and dosage of Rontgen-rays. HERZ, R. H. Feb. 17, 1941, No. 2179. [Class 98 (i)] [Also in Group XXXVI] In apparatus for measuring the quality of X- radiation, a cathode-ray tube is used having a calibrated screen on which are indicated values corresponding to the ratio of the intensities of the radiation before and after passing through a filter. As shown, ionization chambers I<SP>1</SP>, I<SP>2</SP> of similar characteristics are positioned in the path of the rays, a filter F of suitable thickness and material, for example copper or aluminium, being positioned between the tube and the chamber I<SP>2</SP>. Batteries B1, B1<SP>1</SP> supply saturation potentials to the chambers, and the currents produced owing to ionization by the rays set up potentials across high resistances R1, R1<SP>1</SP> in the grid circuits of electrometer valves V1, V1 of high grid impedance. The output of these valves is further amplified by valves V2, V2<SP>1</SP> and is applied to the deflection electrodes A, C and B, D of a cathode-ray tube K. The ratio of the two mutually perpendicular deflections of the beam corresponds to the ratio of the intensities of the filtered and unfiltered radiation and is read on a scale formed by radial lines. The deflection caused by the unfiltered rays is a measure of the intensity of the radiation or of the dosage. For short time and integrating measurements, condensers C1, C2 are connected in parallel with the resistances R1 and R1<SP>1</SP>, the voltages developed then depending on the intensity of radiation and the time during which the condensers are charged. With suitable intensities of radiation and design of ionization chambers the amplifying system may be omitted. Fig. 3 shows two ionization chambers 13, 14 of half frusto-conical shape arranged in the cone P of the X-ray tube, a slot S allowing a filter to be introduced to filter the radiation passing to the chamber 13. With this arrangement the measurements may be made during exposure of a subject. Known condenser type of ionization chambers may be employed, which after charging are partially discharged by exposure respectively to the filtered and the unfiltered radiation, and are then connected to the cathode-ray apparatus to measure the amounts of discharges produced in the two cases. The Provisional Specification describes the use of two photo-electric cells subjected to the light from fluorescent surfaces activated by the filtered and unfiltered X-rays, the outputs from these cells, after or without amplification, being indicated on the screen of a cathode-ray tube as above described. The screens and cells may be arranged in the conical shade of the X-ray tube.

Title: Improvements in and relating to glass blowing apparatus
IPC: C03B9/18
Filed: 1919-02-06
Abstract: 144,344. O'Neill, F. Feb. 6, 1919. Blowing; removing articles from moulds; cutting off excess of metal. -Relates to a semi-automatic pneumatically-operated machine for blowing glass bottles &c. of the type in which turnover mechanisms are carried on rotating tables. According to the invention, the parisons are each transferred mechanically from the parison moulds to the blowing-moulds, and the circular parts of the hinges of moulds do not overlap. The table 17 supporting the parison moulds 95 and the table 35 supporting the finishing-moulds 197 are rotated intermittently through an angle of 60 degrees by a rack 25 and long pinion 32. At the first station, the inverted parison mould is charged by hand, a valve lever being tripped by the punty so as to start the mechanism. The excess of metal is cut off automatically by shears. A cover is brought down on to the mould and air admitted so as to consolidate the metal, the neck is formed by a plunger, which rises from below, and a small puff of air is admitted to prevent the soft glass from falling into the initial neck opening. At the second station the blank is blown in the parison mould. In passing to the third station it is inverted by the action of gearing 115, 148. At the third, or transfer station, the parison and neck moulds are opened and the blank is transferred by tongs 171 to a finishing mould 197. In a modification, each finishing-mould moves radially outwards on the table 35 to receive the parison instead of transfer tongs 171 being employed. At the fourth station, which is 120 degrees distant from the third, the final blowing takes place. At the fifth station the finished bottle is placed on a conveyer 254, which removes it to the leer.
