Title: Improvements in or relating to electromagnetic switching mechanisms
IPC: H01H50/00
Filed: 1941-05-10
Abstract: 549,243. Electrically-tripped switches ; electromagnetic switches. ASSOCIATED ELECTRIC LABORATORIES, Inc. May 10, 1941, No. 6086. Convention date, May 13, 1940. [Class 38 (v)] A number of unit electromagnetic switches 26 arranged one behind the other on a support 12 can only be operated when a master electromagnet 17 is energized ; they are then individually operable through momentary operation of a switch 64, are mechanically latched in their operated positions, and are later all restored to their original positions by de-energization of the master electromagnet 17. Each unit electromagnet 26 is adapted to attract an armature 31 thereby releasing a contact rod 40, which falls on to a V-shaped notch in a common fixed contact plate 39 thereby closing the circuit to a lamp 68. The end 45 co-operates with the end of the armature 31 to hold it in the attracted position. When the master electromagnet is deenergized its armature 25, pivots about 21 under the action of a spring 36 and pushes the armatures 31 back into the position shown. The master electromagnet 17 is energized when a switch 61 is closed and its armature serves to close a maintaining circuit through contacts 48, 50 and a resistance 62 and break the original energizing circuit at 49, 50.

Title: Improvements in or relating to circular knitting machines and methods of knitting stockings thereon
IPC: D04B15/48
Filed: 1924-03-10
Abstract: 212,581. Wildman Manufacturing Co., (Assignees of Howie, K.). March 9, 1923, [Convention date]. Circular machines ; knitting, methods of.-To knit a succession of stockings of equal length and consisting each of an equal number of courses, no special matching to make up pairs being required, the yarn is supplied to the needles by plain or toothed conical or cylindrical rolls 1, 2 in accordance with demands, irrespective of variations of tension, the roll 2 being pressed by a spring against the positively driven roll 1 so as to accommodate itself to changes in the position of the varn. Variations in the varn tension cause the yarn guide to shift in position along the rolls. The roll 2 turns on a rod 3 mounted in a bracket 4 pivoted at 5 to a plate 6 which swivels in a vertical plane in a bracket 10 adjustably fixed to a post 12. The roll 2 is thus enabled to tilt as the yarn passes from a position X, Fig. 7, to a position X<1>, Fig. 8, the rate at which the roll is driven and the yarn fed being correspondingly varied. The top and leg yarns X, Y pass through eyes in sweep arms a<1>, b<1> carried by hollow control members 19 adapted for oscillation and containing mercury which flows from one compartment to another with a vibration damping effect. The screws which secure the arms a<1>, b<1> have extensions 30 which engage projections 29 on cranked slides 28 the horizontal parts of which slide in an overhead guide 27 while the vertical parts 28<a> slide in a hollow standard 22 and are engaged at the lower ends 29<a> by lifting levers 31, 31<a> connected with levers 36, 36<a> for throwing the yarn guides in and out of action and controlled with them bv a drum 43. The arrangement is such that when a guide finger such as 41 is in feeding position, its yarn X is directed by the corresponding control member 19 between the furnishing rolls 1, 2 so as to be fed thereby. A spring 44 acting on a pin 45 gives the member 19 and the yarn guide eye a their initial movement to throw the yarn into the bite of the rolls and thereafter the member 19 can oscillate freely in response to variations of tension the rate of feed being thus varied'. While the guide is finding its proper position along the rolls yarn is supplied by spring-pressed sweeps 46 or 46<a>. Should a yarn fail an adjustable weight 49 on the corresponding disc 19 throws the yarn out from between the rolls.

Patent GB-598597-A (GB)
Title: Improved process of extracting penicillin and product of said process
IPC: A61K31/43
Filed: 1945-03-13
Abstract: A penicillin extract is obtained by mixing a water-immiscible organic solvent for penicillin with a crude aqueous culture containing penicillin in presence of an emulsifying agent in amount sufficient to hasten demulsification but insufficient to produce emulsification and separating off the resulting organic solvent extract from the aqueous phase.  Emulsifying agents which produce oil-in-water emulsions and lower the surface tension of water even in presence of acid are especially useful in promoting a quick "break" of the emulsion into two sharply-defined layers, and such agents may be anionic or cationic in type.  Preferred agents are the sulphated and/or sulphonated higher alcohols sold under the trade names Duponol OS, Duponol ME, Tergitol #7, (sodium sulphate derivative of 3 : 9-diethyltridecanol-6), Tergitol #4, Alkanol WXN, Wecoline A (the ammonium soap of cocoanut oil fatty acids), triethanolamine oleate (either in proportions of 1 : 1 or 1 : 2 of triethanolamine and oleic acid), Aerosal OT (sulphated octyl ester of succinic acid), Tannisol PW (a condensation product of formaldehyde and naphthalene sulphonic acid), Emulphor A (a modified diglycoldioleate), Turkey red oil and Product Q (cetyl trimethyl ammonium bromide).  The amount of emulsifying agent necessary to produce the desired result is critically important for each emulsifying agent selected and the amount in each case must be experimentally determined.  A table is given to demonstrate the comparative effect of the above-mentioned agents against a control, in "breaking" a penicillin emulsion after standing for 5, 10 and 15 minutes respectively.  The effectiveness is enhanced by adding a small amount of an electrolyte, e.g. Tergitol #7 by a drop of 10 per cent alum solution.  Extraction of the crude culture broth with amyl acetate is preferred, but chloroform, ethylene dichloride, butyl acetate, ethers and water-immiscible ketones, e.g. diisopropyl ketone are specified solvents.  Separation of the two phases is effected in any conventional manner, or the emulsion may be passed directly through a Sharples Super Centrifuge without waiting for layer formation to occur.  Specified penicillin crude culture media are the modified CzapekDox medium and a medium comprising corn steep liquor, lactose, sodium nitrate, potassium phosphate, zinc sulphate, hydrated magnesium sulphate and water.

Filed: 1931-02-28
Abstract: 374,099. Control system for lamps. LITE WATCHMAN CORPORATION, 52, Vanderbilt Avenue, New York, U.S.A. Feb. 28, 1931, No. 6351. Convention date, March 5, 1930. [Class 38 (iv).] Emergency lighting systems.-Upon failure of one of a pair of head-lamps in an electric lighting system for self-propelling vehicles, the lamps of another lighting system are automatically energized. The main lighting bulbs 3 and 4 and the supplemental lighting bulbs 5 and 6 of the head-lamps 1 and 2 respectively are supplied from the battery 7 and controlled by the switch 8 the arm 11 of which selectively causes the energization of the two systems. The current to the main lights 3 and 4 divides at a magnetic relay device and passes through equal but oppositely wound windings 17 and 19 respectively which balance and normally have no attraction for the armature 20. Failure of one of the main lamps destroys the balance of the windings and the armature 20 being attracted, establishes connection of the two contacts 22 and 23 which closes a circuit through wire 24 and the metal frame 21 to the supplemental lights 2 and 3, which are immediately energized.

Title: Improvements in or relating to cigarette delivery machines
IPC: A24F15/10
Filed: 1930-02-27
Abstract: 346,920. Cigarette delivery and lighting apparatus. EMMS, E., Sundial, Ebro Crescent, Binley, near Coventry. Feb.27,1930, No. 6454. [Class 75 (iii).] Cigarettes are fed one at a time from a magazine a into a tubular receiver b between an electric igniter c and a suctionoperated plunger d, which is adapted, on rotating the receiver into the lighting position, to press the cigarette against the igniter whilst a current of air is drawn through the cigarette. When the cigarette is ignited, the receiver is further rotated, the plunger being retracted by suction and the ignited cigarette delivered into a chute e by means of springs k<1>, k<2> operating through slots b<4> in the receiver. The igniter comprises a part c<1> carried by a spring c3 and a rotatable part c<4> carrying the filament, projections on the part c<1> being adapted to engage in slots y<1> in the operating lever j to close the circuit at contacts c<2>, c<5> when the receiver is in the lighting position. The receiver is held in that position by a spring catch k. The plunger is provided with a hole d<2> in the inner end and a lateral hole d<3> opening into a chamber g having a port g<2>, the chamber l<1> at the back of the plunger communicating with a passage l in the casing f. The passage registers with parts a<5>, a3, a<4> in the inoperative, lighting and delivery positions respectively, the ports a<5>, a<4> being open to a suction pipe i and the port a<3> open to atmosphere. In the lighting position, the port g<2> registers with a port a<2> open to atmosphere and the suction is automatically regulated by a valve h, which opens against a spring h<1> to admit air to the chamber g when the suction is excessive. The cigarettes are normally supported in the magazine by a spring k<3> which is withdrawn through a slot a<4> by a cam b<3> on the receiver for feeding a cigarette to the latter. The Provisional Specification describes also an apparatus in which the plunger is retracted by a spring.

Title: Improvements in or relating to electron microscope apparatus
IPC: H01J37/20
Filed: 1955-03-04
Abstract: 780,818. Electron microscopes. PHILIPS ELECTRICAL INDUSTRIES, Ltd. March 4, 1955 [March 9, 1954], No. 6459/55. Class 39(1). In an electron microscope the object holder 3, Fig. 2 is arranged externally of the vacuum space and has a bore housing the object carrier, adjustable supports 14, 15 for the object holder arranged symmetrically with respect to the bore, opposite movements of the supports tilting the object in a horizontal plane and equal movements of the supports moving the object in a vertical plane, these movements being permitted by flexible tube 34 coaxial with the bore the object carrier being slidable in the bore for insertion and removal of the object, wherein further adjusting means 38 pivot the holder about the line joining the adjustable supports in order to move the object in the direction of the electron beam. The object holder block 3, Fig. 2, is outside the vacuum space but connected thereto by a rubber tube 5 or possibly by a bellows and has feet 6, 7 pressed against spring-loaded studs 8, 9 by adjusting screws 20, 21 housed in spacing members 14, 15 and having control knobs 36, 37. A third adjusting screw 38 perpendicular to the plane of the paper carries control knob 39. The object at 32 can thus be moved vertically in the plane of the paper by rotating knobs 36, 37 by equal amounts ; to obtain a horizontal component of movement in the plane of the paper, one screw 20 is screwed in and/or the other screw 21 is screwed out slightly. Adjustment of screw 38 causes block 3 to pivot about axis 8-9 and hence causes the object to move along the axis of the electron beam, perpendicular to the plane of the paper. When the object carrier 26 may be pulled out by knob 28, spring biased roller 29 connected by metal strap 33 to ring 34 falls on to seating 31 so preventing entry of air while when 26 is reinserted its bevelled edge at 32 pushes roller 29 back to the position shown. The object carrier 26 is guided and supported in an air tight manner by sheath 25 and rubber ring 27. Metal tube 24 prevents flattening of rubber tube 5 and stud 35 guided in a groove in bore 4 ensures that the object carrier cannot be rotated.

Abstract: 768,246. Concrete block making machines. TRIANCO, Ltd. March 1, 1955 [March 5, 1954], No. 6578/54. Class 87(2). [Also in Group XXX] The concrete block, having been moulded in the mould 1 by the ram 3 operated from the shaft 5 through parallel link mechanism 4, is ejected by the plunger 2 which is raised by the operation of the lever 7 through link and toggle mechanism 9, 10, 12, 13. To counterbalance the weight of the lever 7, plunger 2 and moulded block and to assist in overcoming the friction between the block and the mould, an arm 14 is fixed to the lever shaft 8 and has at its extremity a slot 18 which forms a track along which a weight 21 can move transversely to the arm. When the plunger 2 is down, Fig. 1, the weight is at the end of the track as shown and helps to retain the lever 7 in position. When the operator lifts the lever 7 the weight 21 rolls to the other end of the track and its impact assists in overcoming the initial resistance to ejecting the block from the mould, further movement of the lever increasing the advantage of the counterweight. The weight comprises two masses spaced by a distance piece which forms the centre of a rubber roller 23, this absorbing the shock of impact.

Title: Improvements in or relating to molybdenum alloy steels
IPC: C22C33/04
Filed: 1935-03-02
Abstract: An alloy steel containing from 0,2 to 1,5 per cent of molybdenum, 0,15 to 2 per cent of carbon, 0,3 to 3 per cent of manganese, 91 to 99,2 per cent of iron and, if desired, 0,15 to 2,5 per cent of aluminium is produced in which after the molten constituents have been substantially deoxidized in the usual way and the heat killed, a predetermined amount of an agent, e.g. aluminium or vanadium, is added to produce cementitic dispersion and fine grain size, e.g. of from No. 5 to No. 8 of the A.S.T.M., in the steel.  From 0,032 to 0,8 per cent of p  chromium may be included, the iron content being correspondingly reduced.  Where the steel is made by the open hearth process, and where ferro-silicon is used as the deoxidant, about one-third of the ferro-silicon is added to the molten metal followed by about 1,25 pounds of aluminium per ton of steel, and the remainder of the ferro-silicon.  If the steel is produced in an electric furnace, the oxidation is effected by the addition of ferro-manganese followed by ferro-silicon and from 1 to 1,25 pounds of aluminium per ton of steel.  The aluminium is added when the temperature of the bath is about 2800 DEG  F.  Specific analyses of steel are given.
