Abstract: 1,176,136. Determining thermal conductivity. NATIONAL RESEARCH DEVELOPMENT CORP. May 15, 1967 [March 21, 1966], No. 12289/66. Heading G1D. Apparatus for determining the thermal conductivity of a specimen 11 comprises a datum block 12 including a copper block 14 heated by means 22 and the temperature of which is measured by a sensor 16 and a silica block 12a of known conductivity to which the specimen 11 is secured by a layer 13 of paraffin wax, of known melting point, the upper surface of the specimen being kept at a known temperature eg. by means of ice 23 thereon, and a weight 21 to provide a shear force on the specimen 11 by way of a pulley 19 and cord 20 so that when the wax layer 13 melts, the specimen 11 will be pulled off the block 12, a tappet 19a on the pulley 19 actuating a switch 25 at this moment to cause electrical means 26 to record the temperature registered by the means 16. At this point the temperatures at the ends of the composite block formed by the silica block 12a and the specimen 11 are known and if their thicknesses are also known then the thermal conductivity of the specimen can be found, the known melting point of the wax giving the temperature at the interface between the specimen and block 12a. A cylindrical metal shield 15 surrounds the block 12 and this conducts heat to the edges of the wax layer to prevent sticking due to low ambient temperatures. In an alternative embodiment, Fig. 2, the specimen 31 is rested on a block of wax 32 as a support block 34 in an ice vessel 35, the temperature of the lower face of the wax block is measured by means 36. A vessel 40 containing boiling water rests on the upper face of the specimen 31 and its temperature is measured by means 41. The vessel 40 is guided by balls 42 for vertical movement. The block of wax 32 is arranged to be initially too thick, i. e. the wax melts and runs away until its interface with the specimen reaches the melting point temperature of the waxed conditions are steady. The downward movement of the vessel 40 and specimen 31 is measured by a dial gauge 39 and this is used to determine the thickness of the block 32 at the steady state. If desired the portions of the block 32 and specimen 31 and those of the ice vessel 35 and boiling water vessel 40 may be reversed.

Title: Improvements in and relating to the manufacture of safety razor blades
IPC: C21D9/52
Filed: 1948-05-06
Abstract: Steel strip, for the manufacture of safety razor blades, is degreased and hardened in one operation by passing a length of the strip in one continuous movement successively through (a) a liquid consisting of kerosene and an emulsifying agent; (b) washing water; and (c) a <PICT:0646972/III/1> heating and cooling zone.  The degreasing agent is safe to use in proximity to the hardening furnace, does not evolve toxic vapours, and the presence of the emulsifying agent enables it to be removed from the strip by the subsequent water wash.  The emulsifying agent specified comprises a mixture of cresylic acid and a soap and particularly the product obtained by heating together equal parts of soft potassium soap and cresylic acid.  The emulsifying agent is rendered miscible with the kerosene by means of a small quantity of alcohol such as methylated spirits.  Prior to the water wash, excess contaminated degreasing mixture may be removed from the strip by means of a jet of air and similarly after the water wash the strip may be dried by means of a jet of air before entering the hardening furnace.  The strip being treated is perforated so as to give the blades their outline and apertures while still retaining them in strip form.  Suitable apparatus for the process comprises a passage 1 with slit-like apertures 10, 12 at each end for the passage of the strip, an inlet 11 for the degreasing mixture at one end and an outlet 14 therefor at the other end, a further passage 2 having slit-like apertures at each end for the passage of the strip and an inlet 22a at one end and an outlet 23 at the other end for the washing water, a hardening furnace 4, together with air jet orifices 16, 27 for the removal of excess contaminated degreasing agent and for drying the strip respectively.  The washing passage 2 gradually expands from the end at which the washing water enters so as to promote a high velocity flow of the water over the strip.  The passages 1, 2 are in alignment and each is arranged within a surrounding chamber 5, 6, from which the contaminated degreasing agent on the one hand and the wash water on the other is led away.

Abstract: 444,656. Universal joints. HAMILL, W. W., Beechcroft, Four Oaks Road, Four Oaks, Warwickshire. June 26, 1934, Nos. 12562 and 16531. [Class 80 (ii)] A universal shaft coupling comprise rubber bodies 5 which share the load positively and are closely seated over substantially the whole of their area excepting that occu pying the clearance space, in complementary cavities in the driving and driven members. Adjustable initial compression is applied to the rubber bodies either by drawing the complementary cavities together or by forming the cavities in one or both members as separate sections such as 8, Figs. 1 and 2, bolted together at 81. The rubber bodies may be spherical, square, cvlindridal or ovoidal, in the last case with the major axis radial or axial. In Figs. 1 and 2, the rubber bodies are loaded in compression, and the cavities are formed in interengaging lugs 1, 2 on the coupled shafts, which lugs may, as shown in Figs. 17 and 18 be further separated by lugs 48, 49 on one or more floating intermediate members 48, 49, 50, also provided with cavities receiving rubber bodies, arranged in two or more groups through which the drive passes in series. In Fig. 29 the rubber bodies are loaded in shear, the driving and driven members 54, 58 being directly connected by one group 80 and also by four groups 59, 60 in a series arrangement including three floating intermediate members 55, 56 and 57. Initial compression is applied by axial bolts 61, which draw together the halves of the outer intermediate member 56, and also loosely engage peripheral notches in the shaft-members 54, 58 to limit the relative movement therebetween. Alternatively axial compression may be applied by a screwed end-ring. In modifications, loosely interfitting lugs and recesses on the coupled members limit the relative movement therebetween. The plane of shear of the rubber bodies may, as shown, be substantially radial or be parallel to the shaft axes. Additional initial compression may be applied to cylindrical rubber bodies by screwed bolts, passing axially through them, and having coned heads and nuts engaging in them, or flat washers engaging their ends. Each rubber body may have a metal or hard rubber core and also an integral or loose externally projecting washer filling the clearance space. Surface recesses may be provided in the rubber bodies and cavities to accommodate the flow of rubber under compression, and the outer ends of the cavities are rounded. A part spherical rubber block 9, Fig. 1, or rubber rings may centre the coupling. The coupling-halves shown in Fig. 1, may be fabricated from sheet metal, in a welded, riveted or bolted assembly, Figs. 31 and 32, (not shown). They may alternatively be of aluminium alloy, bronze or delta-metal, and be sand- or die-cast, forged, or pressed.

Abstract: 555,962. Type-bar making machines. TURNER, H. K. (Mergenthaler Linotype Co.). Sept. 8, 1942, No. 12655. [Class 100 (iii)] Ejecting type-bars.-Ejector-adjusting mechanism of the kind described in Specification 541,166 is controlled by a regularly moving organ of the.machine, such as the justification-lever, as it operates during the first machine cycle after the selection of a mould, and the selection of the appropriate ejector is effected by a rotatable stop-carrier geared to the mould-disc. The selection is effected, as heretofore, through a vertically movable selector-bar E<SP>3</SP>, Fig. 2, operated by a lever E, which is held in adjusted position by a pawl e engaging with a toothed sector mounted on the machine frame. When the mould-driving pinion C is drawn forwards by means of its knob C<SP>4</SP> for effecting a change of mould, it rocks an arm G<SP>1</SP> on - a shaft G, which carries a pusher-plate G<SP>2</SP> adapted to retract the pawl e and release the selector-mechanism for adjustment. The lever E is connected to, and operated by, a transverse lever F, Fig. 1, the opposite end of which is connected by a link J<SP>3</SP> to an arm J<SP>2</SP>, Fig. 6, rotatable on the shaft G. The arm J<SP>2</SP> carries a plunger J<SP>5</SP> sliding in a casing J<SP>1</SP> and supported by a spring J. The upper end of the plunger J<SP>5</SP> bears against the justification-lever H, and the spring J is normally in compression. When the pawl e is withdrawn, the expansion of the spring rocks the levers F<SP>3</SP> E and moves the selector-bar E<SP>3</SP> into its lowest or neutral position, corresponding to an ejector of minimum width. When the lever H rises during justification, the levers F, E are rocked in the reverse direction by gravity, and a banking-slide J<SP>4</SP>, connected to the lever F, is raised into contact with one of a series of stops K<SP>1</SP> on a rotatable carrier K, which is geared to the mould-driving pinion C. The stops are adjustable in a radial direction on the carrier by hand in accordance with the length of the various moulds, and are held in position by rack devices.

Filed: 1936-05-06
Abstract: 474,408. Extracting iron. DUFFIELD, F. L. May 6, 1936, No. 12740. [Class 72] [Also in Group XII] In the production of iron, iron ores are granulated, mixed with carbonaceous material and with or without a binding agent, and moulded into blocks, slabs, briquettes or other shaped bodies, the latter then being fed into a bath of molten slag in a furnace interiorly heated by burners, so that they fall into and are submerged in the molten slag and are coated with the latter, the coating protecting them from the oxidizing gases in the furnace. The ore is reduced within the slag coating by the heat absorbed therefrom, and the iron particles drop to the bottom of the bath and coalesce so that they can be removed from the furnace in the form of relatively large masses of semi-molten iron, the latter being removed after the slag has been withdrawn. The iron is afterwards treated to remove any included slag. The process may be carried out in an oscillating furnace a which is heated by combustion of coal dust and 'air admitted tangentially through an aperture c in a cylindrical end chamber e, additional air being admitted tangentially through an aperture d. The molten slag is fed into the furnace through a passage f and the blocks through this passage or an auxiliary passage g. The passage f also acts as an exit for the combustion gases and is then completed by a movable flue k mounted on rollers. An auxiliary air jet l provided in the passage f, is directed towards the interior of the furnace. A slag tap hole n and a discharge door m are also provided.
