Oil swiches have separate oil-filled main contact chambers 28 and auxiliary contact explosion chambers 6. A lost-motion connection, consisting of a spool 19 fixed on the main operating rod 18 and sliding through the cross-arm 16 of the auxiliary contact-rods 14, with an interposed spring 20, ensures that the main contacts are opened first and the auxiliary contacts are allowed a certain amount of rapid free movement. The structure is mounted on a support 1 which by means of the insulators 2 carries the explosion pots containing the auxiliary contacts 12. The contact clamps 9 which hold the auxiliary contacts are directly secured to the fixed main contacts 26 which are moulded within the insulating main container. Thus the main container is supported by its fixed contacts. The movable main contact is mounted on a cross-bar 32 and is guided on rods 33 with intervening springs 34, Fig. 2, tending to push the bridging contact into the off position. A bolt on the cross-bar has a loose sliding connection with the hollow end of the main operating rod. When the operating rod is raised, the springs 34 bring the contact-member to the off position. After the operating rod has acquired some velocity the lower end of the sleeve moves the auxiliary contact-rods rapidly. The explosion chambers are connected with separating and cooling chambers 21 which in turn connect with discharge pipes 22.

Title: Improvements in electro magnetic cut outs
IPC: H01H73/42
Filed: 1925-10-24
Abstract: 242,619. Gross, W. Nov. 7, 1924, [Convention date]. Electrically tripped switches; magnetic blowouts.-A cut-out comprises a normal fuse block 25 having a threaded part 1 and contact plug 2 respectively connected to coils 4, 11. The former coil is connected through strips 5 of ferromagnetic material and a blow-out coil 6 to a contact 7, and the latter coil to a blow-out coil 10 and contact 8. Co-operating with contacts 7, 8 is a contact arm 12 inserted in an insulating block 13 which is rotatably carried on a plate 23 and urged by a spring 14 to move the contact arm 12 into the open position. This movement is normally prevented by a pivoted bell-crank lever having an arm 15 urged by a spring 18 to engage a notch 15<1> in the block 13. An armature 20 is pivoted to a rod 19 forming the common path of the two magnetic circuits containing respectively the coils 4, 11, and under normal temperature conditions the armature, assisted by a spring 22, will be held against the core of the coil 4. When, however, the temperature increases to the change point of the strips 5 the attraction of this circuit is reduced, and the force due to the coil 11 rotates the armature 20, which, by striking the arm 17, moves the arm 15 out of the notch 15<1> and allows the spring 14 to open the circuit between contacts 7, 8. To reset, the block 13 is rotated until the arm 15 re-engages the notch. The coils 6, 10 extinguish any arcs that may be formed. The block 13 may have a release (not shown) to prevent its being held under short-circuits, and the whole cut-out may have a casing with only the block 13 protruding. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the form shown. in Fig. 7 (Cancelled) wherein a single coil replaces the coils 4, 11, the action being just the same. This subject-matter does not appear in the Specification as accepted.

IPC: B64F1/02
Filed: 1959-08-05
Abstract: 913,778. Energy-absorbing devices. FONDEN, P. B., and WALANDER, K. O. T. Aug. 5, 1959 [Aug. 28, 1958], No. 26733/59. Class 103 (1). [Also in Group XXXIII] An energy - absorbing device interposed in the cable of an aircraft arresting gear is shown in Fig. 2, and comprises a cylinder 8 having an end lug 9 for connection to the cable, and a plurality of brake straps 10 connected together and to a lug 13 connected to the cable. Friction pads 11 are applied to the straps by a spring 12, and a shear pin 14 passes through the straps and cylinder. When the tension in the cable rises above a predetermined value, pin 14 clears, and it is arranged that the straps and friction pads can move axially of the cylinder a short distance together, so that the frictional forces of the pads on the straps do not affect the cable tension at which the pin shears. After shearing of the pin, the cable tension extends the straps against the friction imposed by the pads. The thickness of the straps 10 in the region where they pass between the pads when the device is inoperative is reduced, so that the frictional force increases as the straps are withdrawn. A cavity 15 contains a drying agent such as silica gel to prevent corrosion, and has an inspection window. An alternative device is shown in Fig. 4, and comprises a plurality of stainless steel strips 16, with two longer strips 17, connected into the cable at their ends 19, 20. The tension-elongation curve of the device comprises an initial steep portion, a subsequent flatter portion, a further steep portion, as strips 17 elongate, and then a further flatter portion extending to the rupture point. 3, a

Title: Process for the manufacture of compounds of the cyclopentanopolyhydrophenanthrene series
IPC: C07J75/00
Filed: 1938-09-14
Abstract: 518,043. Sex hormones. SCHERINC AKT.- GES. Sept. 14, 1938, No. 26850. Convention date, Sept. 18, 1937. [Class 2 (iii)] Alcohols of the saturated or unsaturated cyclopentanopolyhydrophenanthrene series are prepared by opening by reduction an ethylene oxide ring situated in the side-chain in the 17- position of compounds of the aetio-cholane series. The parent materials may be substituted for instance by keto or hydroxyl or substituted hydroxyl groups or chlorine atoms and of particular importance are those in which the oxygen bridge is between carbon atoms 20 and 21. As suitable reducing agents are mentioned nascent hydrogen from amalgams, activated aluminium or alkali metals and alcohol, and hydrogen activated catalytically for instance by reduced platinum oxide or nickel. Keto groups and nuclear double bonds are protected during the reduction. Compounds prepared in this manner from parent materials containing, in addition to the oxide ring system, a hydroxyl group in the 17-position, can be converted by elimination of water between the hydroxyl group and a hydrogen atom in the 16-position and subsequent reduction and oxidation of secondary alcohol groups into compounds of the type of the corpus luteum hormone. For instance, pregnenedione is prepared from 3:17- dihydroxy-20:21-oxido-pregnene. The elimination of water is effected by heating to elevated temperatures or by the use of agents such as mineral acids, phosphorus oxyhalides, an- 'hydrous metal salts and organic acids. The oxidation of secondary alcohol groups to ketone groups is effected by chromic acid, permanganate or by dehydrogenating agents. In the example, 3:17 - dihydroxy - 20:21-oxido-pregnane is reduced by hydrogen in the presence of reduced platinum oxide to 3-17:20-trihydroxypregnane which on splitting off water between the 17-hydroxyl group and a hydrogen atom in the 16-position followed by reduction and oxidation yields 3:17 pregnandione. Specifications 464,271 and 488,814 are referred to.

Filed: 1955-09-23
Abstract: 773,482. Drawing; forging. AJAX MANUFACTURING CO. Sept. 23, 1955, No. 27243/55. Class 83 (4). In a wire-drawing machine having a reciprocating die 15, Fig. 1, and from which the wire is fed directly to a cold-heading machine &c., a gripping device 16 operating in timed relation to the drawing operation is adapted to stop the wire after a predetermined length of feed. The gripping device 16 comprises a pair of wedgeshape jaws 26a, Fig. 9, movable on ball-bearings 49 in a housing 42 and during the idle stroke of the drawing die when the wire is being fed forward by feed rolls 12, the jaws 26a are automatically closed by push-rods 62 to grip the wire after a given length of feed. The rods 62 are actuated by a cam 58 which is rotated in timed relation with the heading-machine. The cam 58 rocks a lever 59 engaging a plunger 56 mounted in the gripping device 16 and containing a spring 61 which presses against the pushrods 62 through a seating 63. The gripping device is mounted on trunnions 40, 41 and is rotatable to any angle through a worm gear sector 84 operated from a manually rotated shaft 80 so that the jaws 26a which may have a non- uniform pass 16a, Fig. 7, for keystone &c. sections may be turned to orientate the work at the angle required for the heading machine. The jaws 26a are yieldingly located in position by spring-loaded plungers 52 and other springs 50, 53 (not shown), and are operable by frictional drag to grip the work and prevent its movement backwards during the drawing stroke. The die 15 is mounted in a box 14 which is slidably mounted on guides 19, 20. During the drawing stroke it is moved by an arm 22 which engages a flat face 25 on the box and is reciprocated by an eccentric 37 on the same drive-shaft 32 as the cam 58. For initially pushing the work through the die 15, inching devices 17, 18 are provided. The device 17 is reciprocated from the arm 22 by link 27 which can be held out of engagement with the arm 22 by a manually-operated pivoted member 29 during the normal drawing operation.

Abstract: 649,219. Automatic speed control systems. GHALIB, S. A., KELSALL, R. H., HEYS, E., and METROPOLITAN - VICKERS ELECTRICAL CO., Ltd. Oct. 20, 1948, No. 27281. [Class 38 (iv)] [Also in Group XXXVII] In a lathe, boring mill or other machine in which relative cutting movement between a cutting tool and a workpiece is effected mainly by rotation of one of these parts, the speed of the motor driving the machine is automatically controlled so that the linear speed of movement between the cutting tool and the work is maintained constant. As shown, the armature of the driving motor 1 is fed through a mercury arc rectifier 2 and amplifier 5 which is fed with the difference voltage between a reference voltage derived from a potentiometer network 8 and a voltage derived from a tachometer generator 6 coupled to the motor 1 so that for any given reference voltage the speed of rotation of motor 1 is maintained constant. In order to maintain constant linear speed between the cutting tool and the work as the radius of the workpiece gets smaller the potentiometer network 8. is designed to provide a reference voltage which is a hyperbolic function of the linear. radial decrease or increase, so that the speed of rotation of the motor 1 increases or decreases hyperbolically as the radius of the workpiece. The potentiometer P1. is preset, with P2=O for the maximum motor speed required, while the rheostat P2 is driven in linear relation to the radial movement of the cutting tool. The value of the ratio determines the maximum radius at which constant cutting speed can be maintained. The dotted line 10 and switches 10a and 10b indicate how the system can be modified to effect speed control of the motor 1 by varying the shunt field of the motor. Provision for " inching " may also be provided.
