Title: Improvements in or relating to polyphase induction motors
IPC: H02P23/24
Filed: 1929-07-30
Abstract: 319,684. Siemens -Schuckertwerke Akt.-Ges. Sept. 26, 1928, [Convention date]. Alternating-current motors.-A polyphase induction motor of the type comprising two or three stator winding sections two of which are connected at one end by a condenser and adapted to run on single-phase mains is reversed by means of a single-pole two-way throw-over switch which is connected to one of the mains and has its two ways connected to the two winding ends joined by the condenser, the remaining ends of the stator winding being connected to the other main. Fig. 1 shows the application to a squirrel-cage motor having a two-phase stator winding u y, y v joined by a condenser c. The single-phase mains T, R are connected to the junction point y and a twoway switch a respectively. With the switch on contact 1, the current I2 in the winding y v leads with regard to the current I1 in the other winding. When the switch is on contact 2, the current I1 leads and the rotation of the motor is reversed. Fig. 2 shows the application to a motor with three stator windings u y, v y, w y connected in star, two branches being joined by a condenser c and the connection to the main T being made through the third winding. The switch a may be operated manually or by means of a relay.

Filed: 1948-09-07
Abstract: 654,200. Lighting burners. SMITH, G. D. Sept. 7, 1948, No. 23477. Convention date, Sept. 8,1947. [Class 75(iii)] A burner from which fuel normally flows in a cone of a predetermined angle, but initially on starting up flows momentarily in a cone of a wider angle, is combined with an igniter having a cavity or recess therein disposed with its open end in proximity to and directed toward the burner, and within said wider angle but outside of said predetermined angle, a fuel igniter element being disposed in said cavity, and when the burner is started fuel is projected into the said cavity or recess to be ignited by the igniter element, the ignited fuel then flashing back to ignite the fuel stream flowing from the burner, and, after ignition the burning fuel normally will flow out of contact with the igniter. A burner 15 for use in fog dispersal is ignited by an electric heating element 12 disposed in a recess 55 beneath a protecting cover 21 at the top of a hollow column 13 through which passes electric supply leads 60, 61. The burner 15 is adapted to discharge dispersed liquid or gaseous fuel initially in a cone 40 of wide angle to be ignited by the heating element 12. and, after ignition and when the inertia of the fuel has been overcome, to discharge said fuel in a cone 50 of smaller angle so that the flame does not contact the igniter element 12.

Title: Improved method and apparatus for packaging plastic materials in elongated containers
Inventor: BRANDER IAN ROSS
IPC: B29C48/06
Filed: 1960-07-06
Abstract: 919,479. Cartridge-loading machines. IMPERIAL CHEMICAL INDUSTRIES Ltd. July 5, 1961 [July 6, 1960], No. 23612/60. Class 9 (1). [Also in Groups V and XVII] Plastic material, e.g. an explosive, is extruded by a worm 3 through a tube 2 into a container 10 in a reciprocable holder 11, a stream of fluid, e.g. compressed air, being injected through a pipe 5 and manifold 6 to form a layer 8 between the plastic material and the inner wall of the tube 2 before it escapes to atmosphere via the container 10. The air passes from the maniold 6 through the wall of a tubular member 7 of sintered bronze soldered to the end of the tube 2. A compressed air system operates the piston of cylinder 12 on which is secured an arm 13. In rising, the arm 13 trips a lever 14 to operate an air clutch, thereby starting the extrusion mechanism, and to supply air to the member 7. The container 10 is filled to a predetermined extent, the position of the arm 13 on the piston being adjustable. The holder 11 and piston are forced away from the extruder until the arm 13 operates the trip lever 14 to stop the worm 3, cut off air supply to the member 7, and reverse the piston thereby breaking the plastic cord at the narrowed end 9 of the pipe 2. The container 10 may then be removed. The machine may be adapted to fill more than one container at a time, and the containers may be of paper, sheet metal, metal foil or thin plastics material. The construction of the air injection means may be modified, Figs. 3 and 4 (not shown). A circular plate may be secured round the end 9 of the tube 2 to aid in filling containers having a diameter substantially larger than that of the tube 2, Fig. 5 (not shown). The fluid employed in the tube 2 may be a lubricating oil, aqueous lubricant or mineral oil. An adjustable load may be applied to the closed end of the container, e.g. by a spring or piston, in order to govern the rate at which the container recedes during filling. The worm 3 may be replaced by a piston.

Abstract: 898,621. Feeding webs. NATIONAL CASH REGISTER CO. July 14, 1959 [July 18, 1958], No. 24099/59. Class 100(1) [Also in Group XIX] In a record tape sensing apparatus (Group XIX), the tape driving and sensing means (Fig. 1), consists of a frame 121 and an upper part hinged to it, which can be raised to allow the tape to be put in and taken out. Latches 128 and 129 keep the upper part fixed to the frame 121. The tape is fed between reels, photoelectrically controlled means being provided to produce loops to isolate the tape at the reading station from the inertia of the reels. The tape passes over a guide 138, through a brake 105, through the sensing station, over a continuously rotating capstan roller 143 and over a guide 139. Studs 140, 141 guide the tape transversely. The brake 105 consists of an armature 146 which rests on the tape under the action of a spring 154 the pressure of which is adjustable. When magnet 149 is energized the tape is clamped by the armature against the core 147. The brake 105, Fig. 1, may be controlled from the apparatus receiving the sensed data or the end-of-frame signals on the tape may be effective to apply the brake and stop the tape. A circuit is described in detail which detects the end-of-frame signals to stop the tape for a period which may be adjustable. If the tape overshoots the end-of-frame position the brake does not release until a reset button is pressed. Specification 898,622 is referred to.

A peg 18 may be provided on the catch 17 to limit its movement. In a second embodiment the catch is provided with an arcuate slot which engages a peg on the adjustable member thus limiting the movement of the catch in both directions.

[Class 44] A locking means, by which two parts may be connected or disconnected without opening the casing containing them or using an external operating device, consists of a body 10 which under the action of gravity moves into a recess 9 in one of the parts. The arrangement is shown applied to a lock which can be used for left or right handed doors. The latch bolt 4 has an inward extension 5 with a transverse bore 6, and the extension rests in the part 8 of the locking bolt so that the bore 6 forms a continuation of the recesses 9 in the part 8. A coupling pin 10 is inserted in the bore and the entrance closed, the pin being sufficiently long to lock the parts 5, 8 together. To reverse the latch, the lock is turned upside down so that the pin 10 falls into the deep recess 9. The latch 4 can then be withdrawn and reversed. When the lock is again turned to its erect position the pin 10 falls into the bore 6 to lock the parts 5, 8. A member 11 is pressed against the extension 5 by a spring 13 and this closes the recess 9 when the latch is removed so that the pin 10 cannot move into its locking position.

Abstract: Emulsions, particularly those containing protein material and fat, are treated to increase their stability and lower their viscosity by passing them through successive heads or valves of a homogenizing machine.  At the first head a comparatively high pressure is employed, e.g. above 100 atmospheres, and at the following head or heads a substantially lower pressure.  Suitable pressures are 130 atmospheres and 70 atmospheres respectively; the pressure at each valve should be sufficient to produce homogenizing effects.  In the case of fatty emulsions containing casein or egg protein as the emulsifying agent, the first homogenization at least should be performed at a temperature of not less than 60 DEG  C.  When egg protein is used, the emulsifying agent may consist of the egg yolk or the residue left after extraction with ether and chloroform.
