Title: Improvements in or relating to metal-clad electric switchgear
IPC: H02B13/02
Filed: 1936-03-27
Abstract: 472,656. Switchgear structures; oil-break switches. REYROLLE & CO., Ltd., A., ALLAN, A., and BLANCH, N. R. March 27, 1936, No. 9118. [Class 38 (v)] Metal-clad switchgear comprises in combination, two separate but adjoining chambers respectively containing two contacts to be connected together or isolated from one another, an insulated conductor mounted on a ball-joint in the chamber-dividing wall so that its ends project respectively into the two chambers, and means for rocking the conductor about the ball-joint from an operative position in which it interconnects the contacts into an isolating position. Fig. 1 shows one phase of a threephase panel, the other phases being disposed in a line behind that shown. The breaker A has fixed contacts A<3>, A<4>, adapted to be connected to a feeder contact B<1> and bus-bar contact C<1> by insulated conductors, which are mounted in ball.-joints J in the tank-base A<2> constituting the dividing wall between the tank and the chambers B, C. The latter are separated by a wall D, which may leave them in open communication with one another, and have inspection windows B<3>, C<3>, and earthing contacts B<2>, C2. The contacts A<3>, A<4> may have baffle-type arc-control devices and the moving contact A<5> may move vertically or, as shown, horizontally about a vertical axis. The insulated conductor comprises, Fig. 2, sets of butt contacts E<1> interconnected by flexible leads E and provided with control springs E<2>, which abut on partitions F<2> seated in a metal tube F<1> about which condenser-insulation F is wound. To prevent passage of oil through the tube F<1>, a block G, peripheral rubber ring G<1>, and screwed gland ring G<2> are provided. The spherical body J is fixed on sleeves H, H<1> by means of ring H<2>, and engages the inner surfaces of annular blocks K, K<1> which are secured together by bolts K<2> alternating with bolts K<3> for attaching, with intervening packing, the block K<1> to the wall A<2>. A rubber ring K<4> and gland ring K<5> are also provided, and the two conductors are conjointly operated by mechanism L. The invention is applicable also to a duplicate bus-bar arrangement with a separate conductor for the cable, which is provided with an earthing switch, Figs. 3, 4 (not shown), and a bus-bar-sectionalizing switch with spring- butt contacts on the ends of the sections cooperating with rigid contacts on the insulated conductor, Fig. 5 (not shown).

Title: Preparation of tertiary alicyclic amines
Filed: 1952-04-15
Abstract: Tertiary amines having the general formula R1-N(CH3)-R2 in which R1 is a cycloalkyl group and R2 is an alkyl or cycloalkyl group are prepared by treating a primary or secondary amine having the general formula R1-NH-R3, in which R1 is as above defined and R3 is hydrogen or an alkyl or cycloalkyl group, with formic acid and formaldehyde and heating until evolution of carbon dioxide commences, the proportions of formic acid and formaldehyde being at least substantially sufficient to introduce one methyl group into a secondary amine R1NHR2 or two methyl groups into a primary amine R1NH2, R1 and R2 being as defined above.  Preferably, more than 1 mol. of formic acid and substantially 1 mol. of formaldehyde are used per methyl group to be introduced.  In an example, cyclohexylamine (1 mol.) is gradually added to about 2.2 mols. formic acid cooled to 5 DEG  C., followed by addition of about 2.2 mols. formaldehyde, whereupon the mixture is heated to 50 DEG  C. and after evolution of carbon dioxide to 90-95 DEG  C.; on working up N : N-dimethyl cyclohexylamine is obtained as substantially the sole product, a small amount of N-mono cyclohexylamine being obtained if the heating after evolution of carbon dioxide is omitted.  Other starting materials mentioned are those amines R1-NH-R3 wherein R1 may be cyclohexyl, methyl cyclohexyl, dimethyl cyclohexyl and ethyl cyclohexyl and R3 is hydrogen or methyl, ethyl or propyl.

Title: Improvements in and relating to electric motor control systems
IPC: H02P7/26
Filed: 1950-04-18
Abstract: 678,835. Control of D.C. motors. GENERAL ELECTRIC CO., Ltd., and IRVING, H. D. April 18, 1951. [April 18, 1950] No. 9499/50. Class 38 (iii). A control system for an electric motor for a lift, vehicle, conveyer, or the like, which is to be brought to rest in a predetermined position, comprises a high frequency alternating-current tachometer generator and an alternating-current amplifier, the arrangement of the tachometer generator being such that the frequency of its output is sufficient, even at low speeds of the driven equipment, for effective amplification, the output of the amplifier being effective to control the speed of the motor. As shown, the tachometer generator 10 is driven by a lift motor 26 and its output (which may have a frequency of 1,000 cycles per second at the normal speed of the lift) is applied to a transformer 11. The secondary winding of the transformer is connected to rectifier 12 the output from which is smoothed by capacitor 13 and applied, in opposition to a reference voltage derived from potentiometer 15, to the grid of valve 22. The valve is connected, in parallel with resistor 29, in the supply circuit to the field winding 24 of a Ward-Leonard generator 25. The speed of the motor is thus determined by adjustment of the potentiometer 15. The transformer may be replaced by a thermionic valve amplifier. The frequency response of the amplifier or other parts of the system may be modified in order to provide a desired relationship between the speed of the lift and the deceleration to which it is subjected.

Abstract: 557,468. Gas producers. BROWN, J. L., and TAMINI, P. July 9, 1942, Nos. 9558/42 and 898/43. [Classes 51 (i) and 55 (i)] In a gas-producer particularly adapted for the use of sawdust and similar fibrous material, the blast is supplied through a tuyere 12, and the gas is withdrawn through an outlet 7 below a grate 6 at the base of the producer so that the direction of the blast is opposite to that of the outgoing producer gas. A cavity 15 is formed in the fuel bed, and particles of burning fuel are suspended in and whirled in this zone by the air blast. The tuyere nozzle 12 may be provided with lateral discharge nozzles 16, Fig. 4, which direct the air in a tangential manner in a horizontal plane, as well as the vertical discharge 12. The gas outlet may consist of a tubular grate 31, Fig. 7, the lower part of which has cross-cuts through which the gases pass, and the blast nozzle may be surrounded by a shroud 35 of venturi tube form ; further, additional tuyeres 36 may be provided.

Abstract: 1409369 Tyre building machines GOODYEAR TIRE & RUBBER CO 27 Feb 1973 [29 March 1972] 9561/73 Addition to 1337031 Heading B7C The tyre building machine disclosed in Specification 1,337,031 is modified in that the bead ring supporting fingers 159 and the radially expansible part cylindrical segments 148 at each end of drum 110 are moved radially in operation of the machine by pneumatically actuated dual cam assemblies 135. Each assembly comprises two concentric annular pistons 136a, 136b movable axially in annular chamber 134. In operation, introduction of air via pipe 194 causes simultaneous axially inward movement of the pistons to effect, via cam surfaces 138a, 138b and cam follower 171, radially outward movement of the fingers 159 to a bead ring supporting position. With the fingers so positioned (Fig. 14), the piston 136b is halted and piston 136a moves to abut rollers 147, which are prevented from moving radially outwardly by the sleeve 155. Upon subsequent axial inward movement of hubs 130, 131, the piston 136a will be moved by the air in chamber 134 to displace the rollers 147 and thus the segments 148 radially outwardly. The extent of radial outward movement of the segments 148 is determined by the axial dimensions of replaceable rings 141b.
