Title: Improvements in and relating to methods for lubricating textile fibres
Inventor: MUNDY CECIL WALTER ANDRE
IPC: D06M13/224
Filed: 1946-08-08
Abstract: Textile fibres are lubricated by a blend of mineral hydrocarbon oil and oleine acids, upon which enhanced scourability by alkalis has been conferred by the addition of (a) a partial ester of a polyhydric aliphatic alcohol containing one and at most two free hydroxy groups and at least one hydroxy group esterified by a long-chain fatty or hydroxy fatty acid, or a wool fat acid, or a liquid rosin acid, or (b) a long-chain fatty alcohol, or a sterol, or wool fat alcohol, or (c) a mixture of such esters and alcohols, the mineral oil being present in the proportion of from 80 to 20 per cent of the composition, the oleine acids from 10 to 25 per cent and the scouring assistant in a proportion of from 5 to 50 per cent of the mineral oil.  The scouring assistant may be derived from ethylene glycol, diethylene glycol, propylene glycol, glycerol, erythritol, pentaerythritol, sorbitol, mannitol or any other aliphatic alcohol containing at least two hydroxy groups, partially esterified with lauric, myristic, palmitic, stearic, oleic, linoleic, or ricinoleic acids, or a wool fat acid, or any acid from liquid resin.  Mixed partial esters may also be formed by reacting triglyceride fatty oils such as coconut oil, palm oil, palm kernel oil, groundnut oil, olive oil, or lard oil with a polyhydric aliphatic alcohol or mixture of such alcohols.  Small amounts of soap or a sulphonated oil such as sulphonated castor oil may be added, and also antioxidants and emulsifying agents. Examples are given showing the results of scouring trials with lubricants, containing 39 per cent liquid paraffin, 56 to 59 per cent oleine, and 2 to 5 per cent of monoglycerides from groundnut oil, monoglyceride of oleic acid, monoglycol ester of oleic acid, oleyl alcohol, wool fat alcohols, and mixed monoglycol and mono- and di-glyceryl esters from groundnut oil. Specifications 400,681 and 553,562 are referred to.

Patent GB-814107-A (GB)
Title: Improvements in or relating to straight-bar knitting machines
Inventor: HOWITT ALFRED ERNEST
IPC: D04B15/00
Filed: 1956-08-03
Abstract: 814,107. Knitting-machines. MORLEY Ltd., I & R. Aug. 2, 1957 [Aug. 3, 1956], No. 23940/56. Class 74 (2). Preformed rib welts are conveyed to the needles of a multi-division straight-bar machine by loading a conveyer chain with a number of welt transfer bars, one for each division, each of which carries a preformed welt. The conveyer chain is then traversed until a welt transfer bar is positioned before each division whereupon each transfer bar is released from the conveyer chain and is engaged by slides which are actuated to present the welt transfer bar to the needles for the purpose of transferring the welt. After the transferring operation the transfer bar is recoupled to the chain and returned to the loading position for replacement by a replenished transfer bar. The transfer bars may be carried by hooks on the chain and the chain operated such that when the bars are above their respective slides they are disengaged from the hooks and fall into engagement with the slides. To replace the bars after the transfer of the welts they are lifted by arms such that movement of the chain causes further hooks to engage with the bars which are then returned to their loading position. Alternatively the bars are each supported by hooks 4, 4a carried by a movable rod 6. The rod 6 is attached to the lower ends of a frame 7 which can be moved downwardly and upwardly on a bracket 8 towards and away from the slides 2. The bracket 8 is attached to the conveyer chain 1. When the bars attached to the frame 7 are in position above the slide the frame is moved downwardly so that the bar engages its ends in the slides 2. Further downward movement of the frame 7 causes a projection 17 on a lever 15 to engage an abutment 18 on the bracket 8 turning the lever 15 and moving the rod 6 attached to it sideways. This movement disengages the hooks from the transfer bar and the slides can then move towards the needles. The frame 7 is retained in its lowermost position until after the welt has been transferred to the needles and the slides 2 returned to their initial position with the empty transfer bar. Upward movement of the frame 7 then disengages the projection 17 and abutment 18 and the rod 6 regains its original position, under influence of spring 14, in which the hooks 4, 4a re-engage the transfer bar and lift it from the slides 2. After the frames 7 have returned to their uppermost position the conveyer chain is then operated to return the transfer bars to the loading position for replacement. The movement of the frame 7 can be effected by a cam on the main cam-shaft or from the draw-mechanism.

Abstract: 814,170. Positive clutches. TILTMAN LANGLEY Ltd., [formerly TILTMAN LANGLEY LABORATORIES Ltd], Aug. 17, 1955 [Aug. 18, 1954], No. 24063/54. Class 80 (2). A spring engaged claw clutch is disengaged by stopping a control member rotatably mounted on the driving member and having ratchet teeth co-operating with similar teeth on the driven member. A driving member 2 is slidably keyed to the driving shaft 6 and has claw teeth 18 engageable with similar teeth 28 on a driven gear 20 rotatably mounted on bush 21 on the shaft 6. A spring 14 acts through collar 12 and cup member 10 to hold the teeth 18, 28 engaged. A control wheel 36 is rotatably mounted on driving member 2 and has ratchet teeth 34 co-operating with similar teeth 32 on a ring 30 rigid with the gear 20. Engagement of a solenoid operated pawl with teeth 42 on control wheel 36 causes the ratchet teeth 34, 32 to disengage by camming action and move the control member 36 axially. The member 36 acts through a spring disc 40 to move the driving member 2 out of engagement with the gear 20 against the spring 14, and thus hold the clutch disengaged as long as the member 36 is held stationary. The axial depth of the teeth 34, 32 is greater than the depth of teeth 18, 28 to ensure complete disengagement. Means to prevent reverse rotation of the driven members may be provided to prevent unintentional re-engagement.

Title: Improvements in and relating to tunnel kilns
IPC: F27B9/30
Filed: 1924-10-13
Abstract: 245,827. Wilputte, L. Oct. 13, 1924. Tunnel kilns.-The heating or cooling of goods in a tunnel kiln is effected by passing heating- gases or air across the corresponding zones with a direction of flow which is approximately horizontal and is the same at all points in the zone. As shown in connection with a twin tunnel in which two lines of trucks move in opposite directions so that heat is transferred from cooling goods in both end sections to the freshly-charged goods. The kiln consists of a number of structurally independent sections a or a<1>, each section a of the main heating zone having at each side a pair of regenerator chambers E, F for gas and air respectively, while the sections a for the combined preheating and cooling zones have only air regenerators G. The chambers E, F are connected at their upper ends to flues E<1>, F<1>, which deliver to vertical flues D in communication with the tunnel through ports D<1>, and at their lower ends through flues E<2>, F<2> to longitudinal mains K, KA, serving alternately for supplying air and exhausting waste gases. The flues F<2> are permanently in communication with the mains through valve boxes HA having air inlet valves H<3>, while communication between the flues E<2> and the mains can be cut off by valves H<1>. Gas is supplied to the chambers E from a main 0 through branch pipes O<1> fitted with stop valves P and controlling valves O<2>. In operation gas and air are preheated in the chambers E, F at one side of the kiln, combustion is effected in the tunnel, and the products are withdrawn through the opposite regenerators, the direction of flow of the gases being reversed at intervals. The supplies of gas and air are controlled by damper blocks R in the flues E<1>, F<1>, and their distribution in a vertical plane is controlled by throttling-bricks inserted in the ports D<1> and manipulated through access openings A<15>. The regenerator chambers G in the combined preheating and cooling sections of the kiln serve to extract heat from air which has passed through the tunnel and to deliver it again to the entering cold air, thus minimizing the danger of injury to the goods by exposing them to unduly low temperatures during cooling. To equalize the heating of the freshly-charged goods in the two phases of operation gas is continuously supplied through pipes O<3> to the regenerators at the preheating sides of the end sections of the tunnel. In one phase combustion takes place in the regenerators, and in the other in the flues G<1>, D. In a modified construction in which air heating regenerators only are provided in the high temperature zone the flues D serve as combustion flues. When the kiln is constructed to accommodate a single line of trucks flues are arranged so that air which has passed through the regenerator chambers and across the tunnel portion of the cooling-zone, can be similarly passed between the regenerators of the preheating zone. Reference has been directed by the Comptroller to Specification 498/81.

Title: Improvements in and relating to thermo-electric pyrometers
IPC: G01K7/14
Filed: 1927-09-14
Abstract: 290,493. Orchard, J. L., and Cambridge Instrument Co., Ltd. Sept. 14, 1927. Pyrometers.-In a thermo-electric pyrometer for a definite narrow range of temperature, in which a galvanometer &c. is used as an indicator, a bimetallic compensator for variations in cold junction temperature is arranged also to compensate for the temperature-resistance coefficient of the indicator at the said range. The necessity for using a high resistance with the indicator to compensate for the said coefficient is thus avoided and consequently a more open scale can be used for the range of the indicator. The bimetallic compensator 2 is attached at one end to one end of the spring 1 controlling the moving coil of the indicator, and at the other end to an arm 3 secured to a. spindle 4 carrying a pinion 6 and an arm 5. The pinion 6 is engaged by a pivoted rack 8 connected by a spring 12 to a spring-controlled plunger 11. By operating the plunger the spindle 4 is rotated so as to impart initial set to the spring 1 to prevent the indicator pointer from moving until the lower limit of the temperature range of the instrument is reached. The rotation of the spindle 4 is limited by stops 9, 10 with which the arm 5 coarts. A comparatively small series resistance may be used in addition to the bimetallic member for compensating the temperature-resistance coefficient of the indicator.

Abstract: 1493500 Improving physical properties ATOMIC ENERGY OF CANADA Ltd 5 June 1975 [12 July 1974] 24285/75 Heading B3V [Also in Division C7] Improved ductility after irradiation with fast neutrons is conferred on a zirconium alloy containing precipitates soluble in the beta phase but insoluble in the alpha phase by initial solution treatment in the beta region under a protective atmosphere to minimize oxygen pick-up, followed by quenching to produce a super-saturated martensitic phase. The alloy is then subjected to multiple working steps, each reducing the cross-sectional area by 10-20% of the initial value, with intermediate anneals for at least 10 minutes in the alpha region but below recystallization temperature until a total reduction of 70-75% of the initial value has been achieved. Finally the alloy is annealed to achieve simultaneous recrystallization and precipitation with formation of an average grain diameter of 0À1-0À5 microns. A preferred alloy contains 2À4-2À8% Nb, 900-1300 p.p.m. oxygen and balance Zr.
