Title: An improved page printing apparatus for start-stop telegraph systems
IPC: H04L17/22
Filed: 1931-07-02
Abstract: 365,975. Printing telegraphs. CREED & CO., Ltd., Telegraph House, Croydon.- (Assignees of Morton, S., Krum, H. L., and Kleinschmidt, E. E.; Chicago, U:S.A.) July 2, 1931, No. 19080. Convention date, July 11, 1930. [Class 100 (iv).] Relay type-lever actions.-In a telegraphic page-printer, the selector combs 36- admit a selected pull-bar 39 which drops into their combination of slots under the influence of spring 40. Its hook 41 is thus brought into the path of striker-bail 42, which drags it to the right so as to operate a type-lever 43 when the printing-bail 63, which engages the strikerbail 42 at 62, 70, 70, is pulled clockwise by a spring, which if is permitted to do by the restoring-lever 69' when' the latter is moved clockwise under the control of cam 74. The force with which the type-levers strike the platen can be adjusted, for carbon-copying or other purposes, by adjustment of the tripoff bail 65 which, at a given instant, disengages the hook 41 from the striker-bail 42. The type-lever finishes its stroke by momentum, so that the force of the blow depends on the interval which the trip-off bail 65 takes effect.

Abstract: 832,751. Knitting. COTTON Ltd., W. June 26, 1956 [July 1, 1955], No. 19116/55. Class 74 (2). In the successive production, on a straightbar machine, of knitted fabric portions from the   same yarn, each of which portions is pressed-off after completion, the yarn Y extending obliquely from its carrier 5 to the selvedge of a contracted, finished and pressed-off blank on the take-up roller 1 is pulled into a direction YP normal to the needle line and swung down between two adjacent sinkers by a hook 9 adjustably carried on a rod 6 which, by means of a handle 11, can be reciprocated axially, between limits determined by an abutment 12 on the rod and fixed and adjustable stops 13, 16, and oscillated about its axis between limits determined by the cooperation of stops 17, 18 with two faces of the template rail 8. The yarn is thus clear of the points 4 of a point bar 3 as they are advanced to the needles to transfer thereto a length of rib fabric RF in extension of which the remainder of a new blank is to be knitted from the yarn Y. When, as in intarsia or plated work, a plurality of yarns extend from the last blank, a plurality of hooks is used. These hooks may be mounted on a common bar, all the yarns being secured to a cleat at one side of the machine section. When the inclinations of the yarns demand it, the hooks may be in two sets, facing in opposite directions and mounted on two bars 47, 48, the hooks being appropriately located on the rods relatively to such yarns as required to be pulled one way or the other to bring them normal to the needle line. The rod or rods may extend along the length of a multi-section machine, the controls being situated in, or in the region of, an intermediate non-knitting section. Specifications 763,591, 797,871 and 813,435 are referred to.

Abstract: 511,348. Preparation of slagwool. EVANS, O. (Hein & Co. vorm. Haigerer Hutte). Feb. 11, 1938, No. 19138/39. Divided out of 511,149. [Class 56] A method of producing slagwool, rock wool, or the like consists in shredding a stream of the molten material, by a jet of steam or other pressure medium, within lateral walls without rigid upper and lower limits. The molten material flows from the furnace over an inclined channel with a flat bottom 9 which terminates at 10, but the side walls 11 of the channel are continued beyond the point 10. A nozzle 12 for the steam is arranged a little below the point 10, and the shredded, material is confined between the walls 11 which prevent the particles of slag from straying laterally. A smaller nozzle 19 and a guide plate 14 are arranged between the walls 11 to prevent the shredded material from spreading upwards. The stream of slag falling from the point 10 assumes the form of a thin strip which offers a smaller resistance to the steam blast. Specification 511,149 is referred to.

Title: Improvements in and relating to Mass Spectrometric Analysis
IPC: H01J49/14
Filed: 1967-04-27
Abstract: 1,174,502. Mass spectrometers. VARIAN MAT G.m.b.H. 27 April, 1967 [25 June, 1966], No. 19390/67. Heading H1D. In a method of mass spectrometry in which the electron beam acceleration voltage of an electron beam bombardment type ion source is switched between two levels in order to distinguish between molecular masses very close together and in which the lower of the electron beam acceleration voltages lies in the steep commencement region of the ionization function of ion current i versus voltage V, Fig. 2, of at least one of the gaseous components, a gaseous component having particular properties is used as a standard to derive a control magnitude for maintaining the ion current constant in the steep commencement region of the ionization function of at least one of the gaseous components. The standardizing component has, in addition to clearly distinguishable and measurable mass peaks, an ionization function for which the lower electron beam acceleration voltage lies in the steep commencement region and the higher electron beam acceleration voltage lies in the maximum region where the ion current is substantially constant. The control magnitude corresponds to the ratio of the ion currents of the standardizing component derived with the two electron beam acceleration voltages U 1  + U 3  and U 2  + U 3  (U 2  > U 1 ) at the ion collector 11, Fig. 1. The ion current ratio is maintained constant in a preliminary compensation period by adjusting to equality at potentiometer 24 the derived voltages U 11 , U 12 , these voltages being applied via changeover relay 25 to a servo-amplifier 26 and servocontrol 27 for adjusting a variable voltage constituent U 3  of the electron beam acceleration voltage. The relays 25 and 16 are changed over in synchronism and the changeover period need not be divided into equal parts. After the compensation period under the control of a programme generator 17 the various ion currents at collectors 9, 10, 11 are recorded at each of the two electron beam acceleration voltage levels with provision being made for changeover of sensitivity at the potentiometers 28, 29, 30 which are in line with the recording devices 21, 22, 23. The standardizing component may be present in the gas mixture under analysis or added. Instead of utilizing simultaneous collection at a plurality of collectors 9, 10, 11 the mass spectrum may be scanned.

Abstract: 1528070 Valves EFFBE-WERK FRITZ BRUMME & CO KG 13 May 1976 [10 June 1975] 19815/76 Heading F2V The mean position of a machine 6 supported by one or more pneumatic springs 5 is maintained constant by a self-lapping valve 3 operated by deflection of the spring and serving to connect the spring with an exhaust line 16 or a pressurized fluid supply 1, the valve having a restricted fluid flow path which is operative only during small deflections. When the spring 5 is compressed, an arm 34 acts on the valve through a spring loaded plunger 37 to depress a closure 17 to allow fluid from port 14 to flow to port 15 through a throttled passage between stem 18 and its bore until the spring has expanded sufficiently to allow the closure 17 to seat once more. A passage 24 permits unrestricted flow when larger spring deflections occur. Connection of the spring with the exhaust line 16 is established when the spring expands and the stem 18 is lifted, the flow again being throttled between the stem and its bore unless the deflection is sufficient to by-pass the restriction. In a second embodiment, the closure 17 is replaced by a member (28), Fig. 3 not shown), of elastic material, the upper part being of harder material than the lower part which replaces the spring 25 in Fig. 2. The passage 24 is also modified so that it communicates with the port 15 through an annular groove (31). A third embodiment has a lower housing divided into two parts (9a, 9b), Fig. 4 (not shown), sealed to each other by an O-ring (32) while the closure 17 has a cylindrical part with a flattened region (30a) extending into the bore for the stem 18.

Title: Improvements in or relating to processes for treating wool
Inventor: WARD CHARLES FREDERICK
IPC: D06M11/82
Filed: 1947-07-24
Abstract: Textile material of or containing wool is wetted with an aqueous solution of boric acid and dyed.  The treatment with boric acid leads to more even dyeing and protects the material from the harmful action of traces of alkali either from soft water or any previous operation when the wool is dyed by milling acid dyes applied by a process known as "neutral dyeing."  The wool is rendered capable of receiving uniform treatment in subsequent treatments such as chlorination.  The textile material may be in the form of loose wool, yarns, fabrics or articles.  Boric acid up to 10 per cent of the weight of the material may be used.  The material to be dyed may be scoured, bleached or pre-chlorinated before being treated with the boric acid solution. After the material has been immersed in the boric acid solution for some time, the requisite quantity of neutral dyestuff may be added and the solution may then be slowly heated to boiling point and kept at that point until the dye has been absorbed to the desired extent. In an example, knitted wool garment shapes, after chlorination and bleaching with hydrogen peroxide, are treated with boric acid solution at 160 DEG  F. for 15 mins.  Dyestuff is then added and the temperature is gradually raised to the boil and maintained there for 40 mins.  Wool and viscose lace fabric is similarly treated and then subjected to a chlorination treatment which improves shrink-resistance.  Wool and cotton fabric is impregnated with a solution of boric acid and sodium sulphate at 130 DEG  F., and then dyes for the wool and the cotton are added. Wool fabric containing chlorinated and unchlorinated wool is treated with boric acid solution at 110 DEG  F.  Dyes are added and the solution is raised to boiling.  The chlorinated fibres take up the dye very readily whereas the unchlorinated fibres are only slightly coloured.
