Title: Improvements in or relating to controlling devices for arc appliances with vapour orgas discharge path
IPC: H02M1/04
Filed: 1933-11-29
Abstract: 417,742. Converting. AKT.-GES. BROWN, BOVERI, ET CIE., Baden, Switzerland. Nov. 29, 1933, No. 33436. Convention date, Dec. 10, 1932. [Class 38 (ii).] A gas or vapour converter is controlled by a grid, the apertures of which are so dimensioned that Langmuir's dark space at the given pressure overlaps them at voltages equal to those to which the grid would be charged if insulated from the anode sleeve, and means are provided for applying to the grid successively and at will, a positive voltage which ignites, and a negative voltage which extinguishes the arc. As shown, a rectifier a has control grids e mounted in the anode shields d, and additional grids f connected to the anodes by resistances p. The grid e, the apertures of which are chosen on the above considerations, is connected through resistance i to brushes engaging with contacts h, m, on discs g, k, so that at an adjustable instant the grid is connected to the anode, and at another instant is connected to a source of negative voltage n. The brushes in discs g, k, may be coupled so that to a forward displacement of either brush there corresponds a rearward displacement of the other one. Alternatively the discs may be driven by separate synchronous motors, the rotors of which can be adjusted relatively to the rotating field so that to a rearward displacement of the ignition there corresponds an equal forward displacement of the extinction. The positive pole of the source u may be connected to an anode so that separate extinction may be applied to each anode. In a modification, Fig. 3 (not shown), three contact discs may be employed, of which the first ignites the arc, and the second charges a condenser which is discharged by the third to extinguish the arc at the desired moment. Specification 409,331, [Group XL], is referred to.

Title: Improvements in spring buffers for railway and like vehicles
IPC: B61G11/18
Filed: 1922-12-07
Abstract: 200,765. Gatwood, W., and Willans, G. H. Dec. 7, 1922. Buffers.-In a buffer case of the type constructed of a plurality of plate metal pressings, as described in Specification 15791/96, the extra thickness required at the base end of the case or guide to enable the usual securing bolts to be used is produced by stepping up portions of the flanges at the base end of the metal pressings forming the body of the case or guide, and the radius at the nose end of the case or guide has a definite clearance space between it and the radius portion of the junction of the buffer rod and head when the buffer is driven home, as described in Specification 163,923. The casing 1 is formed from pressings having'side flanges 2, the base flange being pressed up at 10 and enclosed by a base plate 9 pressed out at the centre to form a guide 11. The top half of the casing may be shaped to form a foot-step and the abutting edges of the flanges 2 may be welded on the inside at 6, Fig. 3. Instead of the guide 11 being pressed out of the base-plate 9, a casting having projections which fit into the recesses under the raised portions 10 and having a central guide 11 may be used. Cast pieces riveted to a plain flanged base may be used instead of the steppedup portions 10. The nose end of the casing may be outwardly flared and enclosed by a ferrule 4 having a stepped portion 5 and radius which clears the radius at the junction of the buffer head and rod when the buffer rod is driven home. In modifications, the nose end of the casing may be folded back on to the casing either inwardly or outwardly before the casing is pressed into shape and the turned-back edges of the nose may be welded to the casing. A separate ferrule may enclose the nose end, and in all cases the step 5 is formed either by the ferrule or indented on the turned-back portion of the casing.

Button-hole sewing- machines; buttonholes, cutting. - A button-hole cutting punch 28, Fig. 4, is curved edgewise so as to be concentric with the pivot of the cutter-levers and is of a uniform cross section corresponding to the shape of the button-hole. It is held between a pair of recessed clamping- plates 26 secured together by screws 29 and secured to the cutter-bar by a screw 34 which holds the clamp against the walls 24, 25 on the upper cutter-lever. The cutting die 37 is secured by screws 39 upon a lower cutter-lever 20. The cutter-levers are actuated positively by means of cam grooves and auxiliary levers as described in Specification 174,809. The workclamp is moved from stitching position to cutting position in the way described in Specification 146,588 but with a disengaging device modified as follows. The longitudinal movement of the work-clamp during stitching is communicated to it by means of bowls 56, 59, Fig. 16; the bowl 59 working in a transverse slot formed by a wall 60 in the slide frame 54 and an edge 61 on a lever 62. A pin 64 on that lever enters a slot 65 in a lever 66 and when the lever 66 is turned by a cam 69 on the cutter-shaft 3, the lever 62 is raised to free the slide frame 54 from the bowl 59. At the same time a lever 73 is raised, by means of a pin and slot connection with the lever 66, and a bowl 79 on the slide frame passes from the main part to a cross-part of a slot 74 in the lever 73. The lever 73 is then moved by a cam on the cutter-shaft to carry the slide frame and work-clamp to cutting position and back again. The pieces of material removed by the punch are cared for in the way described in Specification 173,411.

Abstract: 816,322. Perspective drawing apparatus. JACKSON, W. H. Feb. 23, 1956 [Nov. 23, 1954], No. 33913/54. Class 97(3) Apparatus for producing on a sheet placed on a drawing board BB a perspective of a diagram placed on the board comprises three straight rods FCOR, TCOR, FR pivoted at 4, 5, 5a and having pivotal interconnection, at 1, 2, 3, provided by members which may slide on or be clamped to the rods, the joint 2 carrying a follower which is taken over the diagram, the joint 1 carrying a marker for drawing the perspective while the joint 3 is constrained to move along a straight line, as by sliding along a rod TR. The normally fixed points 4, 5, 5a are adjustable along a rod CR. In a modification, Fig. 1, the pivot 5a (Fig. 6) of the rod FR is, in effect, displaced to infinity the rod FR being coupled to a device, such as a drafting machine, which maintains the rod parallel to itself while it moves so that the pivot 3 always moves along a straight line. In the form of this modification shown the follower is not attached directly to the joint 2 but to a member FF coupled thereto by a distance rod DCR. A preliminary construction is made using a plan of the object, the line representing the picture plane being drawn thereon together with the plan of the station point and lines through the station point in the directions of elevation planes, which lines intersect the picture plane in the vanishing points. Each elevation plane is considered to be rotated about its vanishing point until it coincides with the picture plane, the position then occupied by the station point, which lies on the horizon line HH, is the "measuring point" Mb and is represented by the joint 4. The "trace" tb, represented by the path of the joint 3, is the intersection of the picture plane and the plane of the object represented by the diagram. The vanishing point Vb is represented by the joint 5 in the form shown in Fig. 1 while, in Fig. 6, it is represented by the intersection with the line HH of the line drawn from the point 5 through the foot To of the perpendicular from the point 5a on to the line tb.

Patent GB-1083633-A (GB)
Title: Improved reagent and preparation thereof
IPC: G01N33/76
Filed: 1964-08-21
Abstract: A reagent comprising altered human chorionic gonadotropin (HCG) adsorbed on spherical particles of synthetic resin in suspension having a particle size of 0.07 - 0.90m  may be used to determine HCG in urine and hence pregnancy by means of an agglutination test using an HCG antiserum, the adsorbed HCG competing with that in the test sample.  The HCG is altered by aging or by heating or by applying digestive enzymatic action and heat to a solution of HCG before adsorption on the particles, or to the reagent.  Specified resins are polystyrene and polymethacrylic resins.  Borate buffers may be used (in an example calcium chloride is present therein also) and sucrose may be added to the final composition.  Details are given of the concentrations and proportions of the resin and HCG employed.  As described the HCG is altered by (1) mixing with the resin, heating to 96 DEG C, cooling to 50 DEG C and maintaining thereat for 2 - 3 months (2) mixing with the resin, adding a trypsin solution, heating slowly to 50 DEG C and maintaining thereat for 2-4 weeks, (3) adding trypsin thereto, heating to 37 DEG C and maintaining the temperature for an hour, increasing the pH and adding the resin suspension, heating to 50 DEG C and maintaining thereat for 2 - 4 weeks or (4) mixing with the resin and maintaining at 5 DEG C for 6 months.  The specification further describes an agglutination test for determining the suitability of the reagent, using an antiserum of known potency in an aqueous diluent containing imidazoline, HCl, NaCl, sodium salicylate, bovine albumin and ethylmercurithiosalicylate or containing imidazoline, HCl and glycine.  An antiserum preparation obtained from rabbits injected with HCG may be similarly tested.

Title: Record carrier with an optically readable trackwise-arranged information structure and apparatus for the read-out thereof
IPC: G11B7/24085
Filed: 1976-08-23
Abstract: It is intended that a read-out spot (V1) can be addressed quickly to a particular information part of the recording carrier (1). The tracks (2) of the recording carrier (1) are subdivided into two groups (a, b). The spacing (d1) between the tracks of the first group (a) is constant, as is the spacing (d2) between the tracks of the second group (b). The second spacing (d2) is greater than the first spacing (d1). The variation in the spacings (d1, d2) between the tracks (2) is about 10% of the average spacing. A read-out beam (11) of a laser (10) is focused by a lens (16) at the read-out spot (V1) on the recording carrier (1). After the reflection at the recording carrier (1), the read-out beam (11) is passed to a detector (14). In order to establish whether the read-out spot (V1) is addressed to the desired group of tracks, an auxiliary beam (l) is used. The auxiliary beam (l) is launched into the path of the read-out beam (11) and produces an addressing spot (V2) on the information carrier (1). The reflected part-beam (l+1) is reflected to two detectors (4, 5), which are connected to a differential amplifier (6). <IMAGE>
