Title: Halogenated and/or sulphohalogenated copolymers of lower olefines and process for their manufacture
IPC: C08K3/22
Filed: 1957-02-08
Abstract: Copolymers of unsaturated hydrocarbons of the general formula CH2=CH R where R represents a hydrogen atom or an alkyl group with up to six carbon atoms which have been made by the Ziegler process are halogenated and/sulphohalogenated by reacting them with a halogen and/or a mixture of a halogen and sulphur dioxide.  The halogenation or sulphochlorination may be effected in air, e.g. by a whirling layer method, or in an aqueous dispersion medium, or in an organic liquid such as carbon tetrachloride, chloroform, or dichloromethane, and the reaction may be assisted by ultra-violet light.  The products may be crosslinked with the aid of a diamine, a polyhydric alcohol, or a metal oxide such as magnesium or lead.  The exemplified polymer is a copolymer of ethylene and propylene.  Specifications 799,392, 799,823, 801,031, 802,843, 810,023, 810,024, 819,867 and 826,639 are referred to.

IPC: F16N7/32
Filed: 1921-02-08
Abstract: 166,864. Blauhorn, E. Feb. 8, 1921. Lubricant conveyed by fluid. - The cylinders and slide valves of a locomotive are lubricated by oil atomized by steam in a mixing-chamber b, which is provided with a non-return valve m in the connection k to the steam-pipe. Oil is delivered to the chamber b by a pump through a pipe, d, and should the outlet i to the cylinder &c. be choked, the oil rising in the chamber is capable of flowing past the valve m into the steampipe a, injury by excessive pressure being thus prevented. The steam inlet l is much larger than the outlet i. so that the fluctuation of pressure in the cylinder is not appreciably communicated to the chamber b. Water of condensation drains through the outlet i into the cylinder. The oilinlet pipe d is provided with a non-return valve g and is formed with an inclined portion f<2> to drain water into the chamber b and thence to the outlet i. A test valve h is provided. Fig. 4 shows two lubricators b connected to a steampipe a which is fitted with a removable sieve c<1> to trap boiler scale &c.

Abstract: 918,990. Protective arrangements; control of A.C. motors. BROOKHIRST IGRANIC Ltd. Feb. 10, 1960 [Jan. 20, 1959], No. 4669/60. Classes 38 (3) and 38 (5). A protective control system for an apparatus' e.g. a motor 10, includes a normally energized relay 15 having its coil 15a shunted by a transistor 27 which is rendered conducting to cause the relay to open its contacts 15b when a thermally-responsive resistor 32 is sufficiently heated due to increase in temperature within the apparatus. In the arrangement shown the resistor has a negative temperature coefficient, but by interchanging the resistor 32 with a resistor 31 in the circuit shown a positive temperature coefficient resistor could be used. When the resistor 32 is sufficiently heated, its resistance is such that the base of the transistor 27 is biased negative with respect to the emitter causing the transistor to conduct and the resulting opening of the contacts 15b causes a contactor 12 to open. A further transistor 21 is connected in series with the relay coil 15a and is normally conducting. Should the circuit including the resistor 32 become open-circuited, then the potential applied to the base of the transistor 21 becomes such that this transistor ceases to conduct and the relay 15 is opened. In a modified arrangement this " fail-safe " aspect is provided by NPN transistor connected across the relay coil. In both arrangements the transistor 27 may be controlled by a plurality of parallel-connected thermally-responsive resistors 32, rectifiers being provided to prevent interaction between the respective parallel circuits, Figs. 3 and 4 (not shown). Ambient temperature compensation may be provided, Fig. 5 (not shown).

Patent GB-548543-A (GB)
Title: Improvements in or relating to apparatus for slotting commutators and the like
IPC: H01R43/14
Filed: 1941-04-11
Abstract: 548,543. Slotting commutators. HOOVER, Ltd., and GILSON, R. J. April 11, 1941, No. 4823. [Class 145 (i)] [Also in Group XXII] In apparatus for slotting commutators by a cutter or saw 4, the work-supporting spindle 7 is normally locked against movement by means of a brake which is released prior to the advance of the work support to the cutter and is reapplied by means controlled by electric contacts which engage the commutator 8 being slotted. The slotting-saw is mounted on a fixed horizontal spindle 3 while the vertical work-spindle is carried by a slide 5 movable by a lever 6 along guide rods 5a. The slide movement is limited by a back stop 10 and by a stop 11 which determines the depth of cut. A ratchetwheel 12 connected to the work-spindle through a friction clutch is operated by a pawl 24 carried by a loose lever 23 engaged by a pin carried by a toothed quadrant 19 pivoted on an extension of the slide 5 and coacting with a spring-urged rack 21. The work-spindle also carries a brake drum engaged by shoes 13 which are normally applied by a spring 15 acting through toggle links 14 and are released by energizing a solenoid 17. The friction clutch of the ratchet wheel slips at a lower torque than the braking torque. When the slide is moved back from the saw by the lever 6 the rack rod engages a stop 25 and is then moved to turn the quadrant and actuate the ratchet wheel. During this movement a contact 26 on the slide engages a contact 27 on the bed to complete the circuit of the solenoid and release the brake, Fig. 4. The commutator is engaged by a pair of brush contacts 28 connected to a common point and by an intermediate contact 29, these contacts being arranged in the solenoid circuit as shown in Fig. 4. For cutting conductor slots the brushes are adjusted so that when the cutter is opposite the centre of a bar, Fig. 1, the brush 29 engages one of the mica strips between the bars. At the time that contacts 26, 27 separate, the commutator has been moved so that the contacts 28, 29, now complete the circuit and maintain the brake disengaged. When the commutator has been advanced by the angular distance of one segment the brush 29 engages the next insulating segment and breaks the circuit whereupon the brake is re-applied. If the commutator position is incorrect the circuit between the brushes 28 and 29 is not broken and a solenoid 32 then causes a stop 30 to be brought into the path of a stop 31 to prevent the slide being moved up to the cutter.

Title: Improvements relating to air-break circuit breakers
IPC: H01H9/44
Filed: 1952-02-25
Abstract: 714,526. Arc-rupturing in switches; switch contacts. SWITCHGEAR & COWANS, Ltd., and ROWLAND, F. G. Feb. 11, 1953 [Feb. 25, 1952], No. 4861/52. Class 38(5) An air-break switch has a deep arc chute 4 which completely envelops the fixed and moving contacts 5, 11, a hoop 19 of magnetic material around the chute above the level of the contacts, and separate fixed magnetic members 20 inside the chute and above the level of the hoop. When the arc 21 is drawn, it bows up into the space enclosed by the hoops and the flux set up by the arc links with the hoop 19. With light current arcs, Fig. 6, the flux inside the arc loops is strengthened to move the arc rapidly into contact with the magnetic members 20. The flux in linking with the hoop 19 and with the members 20 as the arc rises in the chute, brings the arc into close contact with a side of the chute, the ends of the chute and the members 20 to ensure maximum cooling and deionizing of the arc. Under high current arc conditions, the ends of.the hoop 19 saturate and some of the flux returns over the arc, Fig. 14, to prevent the arc rising too rapidly. The members 20 may be plates of magnetic material extending across the chute transversely to the arc. Alternatively the members 20 may be magnetic plates split longitudinally and provided with insulating centre portions or air gaps. In a modification, Fig. 16 (not shown), spaced plates of insulating material are provided and strips of magnetic material are inserted between them on both sides of the chute. The hoop 19 may be provided with an air gap at each end, and may be extended so as to link with a blow-out coil, Fig. 15 (not shown). Switch contacts: The moving contact assembly comprises pivoted arms 10 carrying a pivoted contact 11 which is biased by compression springs 13, 14. A stop 15 limits the movement of the contact 11 relative to the arms 10.

Filed: 1916-04-05
Abstract: 101,384. Corley, Q. D. April 5, 1916. Limbs, artificial.-An arm is provided with various means for grasping and manipulating objects and is designed so that the objects can be manipulated and the arm fitted on the person by people who have lost both hands. A forearm socket 1 is articulated to a divided sleeve 2 laced on the upper arm, and the laces are passed finally round friction hooks acting as locking-devices to prevent the lace from running back, thus enabling the wearer to draw the laces tight by holding the ends in his teeth. The lower end of the socket 1 carries a double clutch operated by the screw 15, which has an elongated head adapted to he rotated by the teeth or by friction against a table. The two clutch elements 13, 17 form part of a guided hollow rectangular frame 12. The element 17 co-operates with a slotted plate 16 and a socket 18 to hold the handles of knives, forks, &c., which are picked up by sliding the pointed end 19 of the socket underneath them. The element 13 co-operates with a fixed clutch element 10 to grasp a grooved stud 26 on the end of a combined hook and spring grasping-device, shown in Fig. 3. The upper member 21 is formed with long and short hooks 22, 23 respectively, which have hooked points 24 arranged as shown. The lower member 27 is spaced from the plate 21 and is provided with a depression 28 at an angle with its main axis. This member only extends laterally under the longer hook 22 and normally abuts against the under surface of the hook, except at the extreme end 29, which is curved downwardly and reduced to a fine edge to facilitate insertion under an object, such as a sheet of paper or a coin. By rotating a ratchet-wheel 30 carrying three cams 30<1>, the member 27 is alternately sprung downwards into the position shown in dotted lines in Fig. 1 and released again. Suitable objects may thus be grasped between the hook 22 and the member 27. Round objects, such as pencils, are additionally supported in the depression 28, as shown in dotted lines in Fig. 3. To operate the ratchet-wheel, the wearer first bends the forearm and pushes the pawl lever 31 in an anti-clockwise direction with his teeth. Then, on straightening the arm, the lever is moved in a clockwise direction through the medium of the cord 34 to operate the ratchet-wheel. The main hooks 22, 23 are used for lifting purposes, while the hooked points 24 are stated to be useful for buttoning clothes, opening purses, and tying and untying strings.

Abstract: 1,183,272. Electric synchronism indicators; synchronizing. SATCHWELL CONTROLS Ltd. 21 Jan., 1969 [31 Jan., 1968], No. 4993/68. Heading H2L. To detect loss of synchronism between pairs of uniselector switches in a data transmission system each switch 15, 16 has an additional bank, the fixed contacts of which 0 ... 6 are alternately connected to potentials of opposite polarity while their wiper arms 12, 13 are connected to means responsive to the applied potentials and arranged to detect if the switches are in synchronism. As shown, the arms are connected to relays 17 . . . 20 which carry contacts connected between terminals 21, 22 and 23, 24 in indicator lamp and lockout circuits, not shown. The relays and their contacts are so arranged that if the wipers are on terminals of like, polarity (i.e. in synchronism), a circuit is completed between 21, 22 but not between 23, 24, and vice versa. In an alternative embodiment (Fig. 2, not shown). there is only one relay, which is connected between the wiper arms, and thus this is energized if the arms get out of step. Operation of the relay causes the arms to stop and return to a datum position in an unspecified manner. In, this embodiment, there are a number of uniselectors at, each station, which are brought into use sequentially.
