Title: Improvements in or relating to knitting machines
IPC: B04C5/12
Filed: 1930-05-19
Abstract: 355,246. Knitting. SPIERS, Ltd. W. and SPIERS, E., XL Works, Walnut Street, Leicester. May 19, 1930, No. 15309. [Class 74 (ii).] Fashioned seamless hosiery &c. is made upon a warp machine having parallel needle beds and independently-operated needles. Curved bearded needles as described in Specification 355,252 are preferably proviced. The needles 2 are arranged in outwardly concave beds 1 and are actuated by selector members 12 under the control of jacquard bands 15. The :nembers 12 are arranged in beds 29 pivoted at 31 so that their inner ends are moved parallel to the beds 2. The members 12 are returned to norn al position by members 151 after selection by the bands 15. The jacquard bands allow additional needles to be inserted for fashioning, and are preferably so designed that alternate needles are selected for operation at one side of the jacquard drum 17, and the intermediate needles are selected at the next pick. The number of bobbins or other yarn supplies is thus halved. Guides 36, 37 are provided for supplying yarns to one bed of needles, and corresponding guides 36a, 37a are provided for the other bed, the guides being moved from the position shown in full lines in Fig. 3 to that shown in chain-dotted lines, and an auxiliary guide 38 is provided for supplying yarns to needles in both beds to unite the knitted webs to form tubular fabric. The guides are preferably shogged in one direction by a Dawson wheel or cam, and in the reverse direction by a spring. Each of the guides 36 .. 37a preferably comprises a pair of members, a fixed part A, and a part B movable under pattern control longitudinally of the part A. The part B serves to supply yarns to the additional needles selected for fashioning, and when brought into register with the part A may supply splicing yarns, e.g. for the toe, heel or high splice. The auxiliary guide 38 also comprises two sections 112, 113 slidably mounted so that the suture yarns may be fed to the outside needles forming fashioned parts of the fabric. An electrically operated stop motion may be provided, actuated upon breakage of the yarn fed from any of the supply bobbins.

Title: Control circuits for d c motors
IPC: H02P7/298
Filed: 1973-03-30
Abstract: 1424223 D. C. motor control 30 March 1973 [3 April 1972] 15364/73 Heading H2J A control circuit for a D.C. motor, e.g. in a vehicle, has a first switching means for controlling the direction of current through the field winding 15 with respect to the current through the armature 13, a second switching means for selecting either a series or a shunt connection mode of operation of the motor, and a controller 31 to vary the mark/space ratio of current pulses from a source to the field winding when in the shunt mode and to both the field and armature when in the series mode whereby to control the motor speed. As shown, when contacts 35, 37 are open and normally closed contacts 17, 19 are closed, the motor armature 13 is in series with field 15 and is energised when operation of switch 29 energises coil 25 or 27 to operate two pairs of contacts F1, F2 or R1, R2, respectively and produce forward or reverse rotation i.e. by closing F1 and R2 or F2 and R1. Each pair of contacts is mechanically interlocked-e.g. when F1 is open F2 is closed. The mode of operation is changed to shunt connection by the closing of contacts 55 when a slider 53 of a variable resistance 49 is moved fully clockwise. A timer 66, started by the closing of contacts 55, after a few seconds energises a coil 23 which opens contacts 19, and closes contacts 37, 63 connecting the field in series with controller 31 across the supply and energising a coil 21 which in turn opens contacts 17, 57 and closes contacts 35, 56 connecting the armature across the supply and reversing the connections to the resistance 49 to give maximum resistance in series with circuit 31 and hence minimum field current. A timer 68 is started by the closing of contacts 63 and after <SP>1</SP>/ 10  second energises coil 67 which closes contacts 75 to allow maximum current to flow in the armature. In an electric vehicle the slider 53 may be connected to an accelerator control so that the change in the effective value of resistance 49 causes the control circuit 31 to change the mark/ space ratio of current supply and hence the speed of the motor and vehicle.  When operating in the shunt connection an armature current sensing circuit including resistor 41 and transistor 84 causes control circuit 31 to increase the field current proportionally if the armature current exceeds a predetermined value due to increased load. If the armature current exceeds a higher predetermined value an overload current sensor 62 causes contacts 61 to open and the motor is switched back to series operation.

Title: Method of and furnace for coating pipes with metal
IPC: C23C24/10
Filed: 1937-06-04
Abstract: 478,938. Coating pipes with metal. BRAUN, M. June 4, 1937, Nos. 15533 and 15534. Convention dates, June 18, 1936 and July 21, 1936. [Class 82 (ii)] [Also in Group XII] To coat pipes internally with metal the pipes are charged with the coating metal and rolled intermittently over a stepped support through a heating furnace to melt the coating metal. An inert atmosphere is maintained in the furnace. In the form shown in Figs. 1 and 3, the inlet b of the furnace is sealed by a roller a which has longitudinal grooves which receive the pipes and transfer them onto a platform which is wide enough to receive a plurality of pipes. The platform c is the uppermost of a series of steps g which form the bottom of the furnace, the steps g preferably varying in width and depth. The pipes are transferred from step to step by reciprocating push rods e<1> actuated by eccentrics e on a vertical shaft d. From the bottom step i the pipes pass into an inclined channel containing a cooled hollow roller l having brackets which support the pipes. On rotation of the roller through about 90‹ the pipes are passed into an inclined discharge passage m beneath which is a conveyer n which delivers them ,into a water bath o. The tilting of the pipes in the channel k ensures the discharge of surplus coating metal. The furnace may be heated by electric heaters h or by gas or solid fuel and, as shown in Fig. 3, it may comprise two separate stepped bottoms and discharge passages. The form shown in Fig. 5 is used when a thick coating is desired and includes an inclined delivery plane q down which the pipes roll after passing down the stepped bottom. The end portion of this delivery plane is cooled by water or air sprays r. The pipes pass into a drum s which has an open top and which, when a number of pipes have accumulated therein, is rotated to discharge them into a water bath t.

Patent GB-970224-A (GB)
Title: Analytical procedure and apparatus for the identification and classification of bacteria
IPC: C12Q1/04
Filed: 1963-04-22
Abstract: The fermentation ability of micro-organisms is identified and determined without danger to false positive reaction by placing a liquid medium containing a carbohydrate in a receptacle, inverting in the medium in the receptacle a capillary tube which is open at only one end, the capillary tube being so placed that the open end is below the surface of the liquid culture medium, autoclaving to replace all the air in the capillary tube and to fill it completely with medium, inoculating the medium with a microorganism, incubating sufficiently to promote the fermentation of the medium by the microorganism and checking for gas bubbles and evidence of acid formation.  The capillary tube should be of clear glass, between 10 and 40 mm. long, and between 0.03 and 0.06 inch internal diameter. The culture medium may contain 1% of a carbohydrate such as glucose, inositol, lactose, maltose, mannitol or sucrose, and a pH-sensitive indicator. Bacteria specifically mentioned: Escherichia coli, Aerobacter aerogenes, Alcaligenes fecalis, Proteus vulgaris, Salmonella paratyphi and Salmonella typhosa (both inositol-fermenting and non-fermenting strains).  In the procedure of an example, 0.3 ml aliquot portions of phenol broth culture medium containing 1% added carbohydrate were delivered to small culture tubes (6X50 mm.).  A micro-capillary tube (0.03 inch and 10 mm.) sealed at one end was placed open end downward into the medium in the culture tubes.  These were then stoppered with plastic foam and exposed to a temperature of 121  DEG C. at 15 pounds pressure for 15 minutes, during which the medium completely displaced all air from within the micro tubes. Single colonies, approximately 1-3 mm. in diameter isolated on initial plating medium, were used to inoculate each tube of test medium and the cultures were then incubated at 37  DEG C.  In appropriate cases, acid production was detectable in as little as 10 minutes after inoculation and a small gas bubble was often observed in the collection tube after only a 30 minute incubation period.

Title: Improvements in the welding of transition pieces
Inventor: HOULDCROFT PETER THOMAS
IPC: B23K20/12
Filed: 1963-04-22
Abstract: 1,082,611. Welding by pressure; welding by fusion; rolling. BRITISH WELDING RESEARCH ASSOCIATION. April 20, 1964 [April 22, 1963], No. 15782/63. Headings B3M and B3R. In making a metal transition piece a tube of one metal is friction-welded to a tube of another metal and the resultant member is worked to modify its shape or thickness. Two tubes are friction-welded end to end, one being rotated and the other held stationary, and the welded member is split longitudinally and rolled flat to a sheet of reduced thickness from which thin flat transition pieces are cut. Alternatively, the welded member may be rolled between an inner and an outer roller to produce a thin-walled cylindrical transition piece. In a modification, a tube 12, Fig. 5, of a first metal is placed within a tube 13 of the first or a second metal and the ends of the tubes are friction-welded to a further tube 14 of a third metal having a wall thickness equal to the combined thickness of the first tubes. The resultant member may be split and rolled as described and the superposed sheets may be separated to form a T-shaped transition piece. Alternatively, the resultant member may have the outer tube 13 prised away and spun to form a flat disc. Such a construction may be used when as in Fig. 7 a transition piece comprising a threaded stainless steel outlet 14, a tube 12 and a flange 13, is used to connect a tubular member within an aluminium vessel 15 to an external tube and to connect both to the wall of the vessel. Transition pieces formed of copper-aluminium or aluminium-stainless steel may be produced.

Title: Improvements in or relating to methods of cleaning iron ore fines, notably for the manufacture of improved ferrous coke
IPC: C22B1/14
Filed: 1957-05-20
Abstract: Iron ore fines, such as blast furnace dust, are cleaned in a process which comprises roasting the ores without circulation of air to decarbonate them almost entirely and to reduce them at least partially, then separating the barren constituents, the roasting and separation being effected by using the sensible heat of coke during the course of coke manufacture and the subsequent p  extinguishing of the coke by wet or dry methods.  The ore fines may be spread over a bed of incandescent coke discharged from a coke oven, the ore then being separated from the greater part of the barren constituents by being washed with water as the coke is quenched and by gravimetric classification in the collected wash water.  Alternatively the fines alone or mixed with coal may be roasted by being spread over coal coke in a thin layer during the coking operation.  In a further modification the ore fines are spread over a coke cake which has cooled to a temperature of about 300 DEG C., the coke being extinguished in the absence of a liquid quenching medium or air circulation.  The fines are then separated from the coke and are spread over a coke cake at a temperature of about 1000 DEG C. and are separated therefrom when the coke has cooled to about 700 DEG C.  The roasted and separated fines are then washed with water and separated from the greater part of the barren constituents by gravimetric classification in the collected wash water.
