Title: Improvements relating to dynamo-electric machines
IPC: H02K5/16
Filed: 1959-05-29
Abstract: 892,391. Fluid bearings. MACKS, E. F. May 29, 1959, No. 18399/59. Class 12 (1). [Also in Group XXXV] In a dynamo-electric machine the rotor 10 and stator 14 have smooth complementary cylindrical surfaces, the radial spacing between them being such that when the rotor operates, a film of ambient fluid such as air formed between the surfaces supports the rotor in the radial direction. In a modification a sleeve of non- magnetic material is placed inside the stator, the film being formed between it and the rotor (Fig. 2, not shown). When the rotor is mounted vertically, an end-plate on the stator co-operates with the end of the rotor to form a thrust-bearing film (Fig. 3, not shown). To obtain such a film the end of the rotor or the stator end-plate is modified to have segments recessed below the plane of the surface (Fig. 4, not shown). The segments do not extend completely from rim to centre of the surface so reducing end leakage. A ball-type thrust bearing may be provided to support the rotor vertically (Fig. 5, not shown). In a further modification the rotor 10 has a bore 36, concentric with rotor shaft 12 and into which fits stud 38 fixed to the stator 14, the film being formed between bore and stud. Similar modifications may be made having ball thrust bearings between rotor and stator housing (Figs. 8, 9, not shown) and when the rotor is mounted vertically the end of the stud is recessed as described above. In another modification the shaft 12 has an enlarged portion 40 adjacent the rotor to co-operate with a bracket 41 fixed to the stator to form the film. To prevent axial movement of rotor and stator a stop-bracket coacts with an extension on the rotor shaft (Fig. 12, not shown). When this modification is mounted vertically a thrust-bracket on the enlarged shaft portion co-operates with the end of the stator bracket to form a thrust-bearing film (Fig. 13, not shown).

IPC: F16H15/42
Filed: 1927-07-15
Abstract: 298,676. Garrard, C. G. July 15, 1927. Variable-speed and reversing gearing comprises an epicyclic train controlled by friction gearing of the kind with cones such as 15, 22, Figs. 1 and 5, connected by a movable ring such as 26, or by a movable, roller or ball. Means comprising a cam such as 24, Fig. 1, produces axial thrust in the cone gearing ensuring adhesion. In the arrangement of Fig. 1, there is a toothed epicyclic train 11, 12, 13 two members being geared to the two cones 15, 22. The ring 26 encircles one cone and is shifted to change speed by a shipper 27 which tilts the ring so that it creeps automatically sideways along a spiral path. When the cones are connected by a roller, the axis of this is tilted to get this creepimg effect. A ball may be used to connect the cones, and the whole may be controlled by a governor. The speed changes are gradual through neutral to reverse. In Fig. 2 is shown a friction epicyclic train 37, 38, 50 controlled by a form of the friction variable gearing having a central cone 34 and three spaced coacting cones 43 with encircling idlers 26. The thrust cam device 35 produces adhesion both in the epicyclic train and in the auxiliary cone gearing.

Abstract: 1383416 Cinematography EASTMAN KODAK CO 24 April 1972 [23 April 1971] 18854/72 Heading G2E Although applicable to any web handling apparatus, a modification of the film stripping mechanism of Specification 1300976 senses when the stripping mechanism is moved past its active position in which it could engage web roll 21' of at least predetermined size. This indicates that the roll is of less than this size and the stripping mechanism is prevented from being latched in the active position. When a small web roll of 21', Fig. 3, is present the stripping drive member 24' rises sufficiently for tooth 104a on member 74' to rise and engage tooth 103a. Further movement after this engagement rotates snubber arm 88 causing latch arm 99a to remove tab 100a clean of tab. 102a. When a roll 21' of at least predetermined size is to be stripped the member 24' does not rise sufficiently for teeth 103a, 104a to engage. Thus tabs 100a, 102a engage and hold the member 24 in the stripping position.

Abstract: 1,202,668. Cutting device. HEBERLEIN & CO. A.G. 14 April, 1969 [13 May, 1968], No. 19044/69. Heading B4B. [Also in Division B3] A cutting device for filaments &c. comprises a cutter 9 operable by an electromagnet armature 4, one end of the cutter 9 being pivotably seated in a recess 8 of a coupling member 6, whilst the cutting end is slidable over a fixed knife 14, spring means 11 connected between the cutter 9 and a fixed point 12 urging the cutter 9 into contact with the knife 14 and exerting a return force on the cutter 9 and armature 4 after each cutting movement. The knife edge is formed as a circular hole 14a in a plate 14, a slot (15), Fig. 2 (not shown), allowing insertion of the material 16 to be cut, and a catcher 10 rigid with the cutter 9 engages a fixed resilient pad 17 to trap the cut-off piece. Operation.-A metal ring 26 and insulating ring 27 are mounted on the end of the armature 4, and at the start of a cutting cycle, a switch member 25 contacts the metal ring 26 such that a resistance 24 is bridged. On actuating the circuit, Fig. 5 (not shown), a current flows in a magnet coil 3 to actuate the cutter 9. The bridging is broken when the member 25 contacts the insulating ring 27 and the stroke is then completed under a greatly reduced current through the resistance 24 until a conical magnetic surface 5 of the armature 4 strikes a core 20, a switch (28) in a sensor finally breaking the circuit. However, if the material 16 has not been fully severed, the members 5, 20 remain separated by an air gap, the cutter 9 being withdrawn by the spring 11 so that the stroke is repeated automatically.

Filed: 1958-06-16
Abstract: 897,082. Electric clocks. OBERGFELL, R., and OBERGFELL H., [trading as KIENINGER & OBERGFELL.]. June 16, 1958, No. 19185/58. Class 139. In an electric timepiece the mechanical oscillator is maintained by mechanical impulses and the maintaining circuit includes pick-up and driving coils connected respectively to the input and output of a transistor. In the first example, Fig. 2, the balance carries a permanent magnet 2 which, as the balance swings in one direction, induces an impulse in the coil 1 connected with a stabilizing resistor 25 between the base and emitter of a transistor 22. The driving coil 21 connected between the collector and the emitter rocks an armature 17, 24 which steps-on a ratchet wheel 18 of the going train and tensions a spring 14 which is released to impulse the balance on its return swing. The permanent magnet may be formed by casting a magnetic powder into or on the balance and thereafter magnetising the powder. A pair of permanent magnets may be used. In a modification the return spring of the armature effects the rotation of the ratchet wheel. In another example the armature steps-on a ratchet which co-operates with a detent on a pendulum and thereby impulses the pendulum. The armature may operate on the magneto-striction principle to drive the ratchet. In another example, Fig. 5, the outer end of the balance spring is fixed to a lever 106 which therefore oscillates in synchronism with the balance. The pick-up coil 107 is mounted on the lever 106 and co-operates with a stationary permanent magnet 109. The drive coil energizes a magnet 115 which rocks the armature lever 116 to drive the ratchet wheel 129 through the pawls 127, 128 and impulse the balance through the fork 123. In another similar example, Fig. 6 (not shown) the permanent magnet is replaced by a stationary coil. The pick-up coil and this additional coil may both be stationary, the feedback between the coils being varied by a member carried by the arm to which the outer end of the balance spring is attached. The mechanical oscillator, the driving components and the electronic circuit components may form a constructional unit.

Title: Process of producing solidification of oleaginous substances
Filed: 1919-08-05
Abstract: Tung oil or Chinese wood oil is solidified by the action of haloid salts, particularly chlorides, uniformity disseminated through the oil.  To secure this dissemination, the chlorides are first ground up with an indifferent oil, such as resin oil or linseed oil, or dissolved in an anhydrous organic solvent, and the liquid produced mixed with the Tung oil.  Suitable combinations of salts and solvents are anhydrous ferric chlorides in anhydrous acetone, anhydrous aluminium chloride in anhydrous acetone, anhydrous stannic chloride in acetone, anhydrous zinc chloride in amylacetate or alcohol, and antimony or bismuth chloride in acetone; the use of ferric bromide is also mentioned, and mixtures of various salts may be employed. Fuming chlorides, such as antimony chloride or stannic chloride may be dissolved in benzene or its like and mixed with an indifferent oil and the mixture added to the Tung oil, or they may be changed into hydrated chlorides and dissolved in an hydrous solvent and used directly. Resin gums, ester gums, or other gums easily soluble in oil may be added to the Tung oil, as may Tung oil fatty acids.  Either raw or blown Tung oil may be employed, but oil that has been partly polymerized by heat is unsuitable.
