Title: Electric motor shaft seal
IPC: F16J15/34
Filed: 1964-09-24
Abstract: 1,045,249. Seals. WESTINGHOUSE ELECTRIC CORPORATION. Sept. 24, 1964 [Oct. 23, 1963], No. 38973/64. Heading F2B. In a motor-pump unit comprising an impeller 22 driven through a shaft 36 by an electric motor 171, the shaft 36 is sealed by means comprising a sleeve 64 surrounding the shaft, a first controlled leakage seal 108 constructed to permit a relatively small flow of leakage fluid therethrough, means for removing such leakage fluid, and a second controlled leakage seal 94 disposed between the pump end of the shaft and the first seal so that the flow of leakage fluid through the first seal also passes through the second seal which is formed to reduce the pressure thereacross when there is a relatively larger quantity of fluid flow therethrough, whereby said second seal is normally substantially inoperative but becomes effective when a failure of the first seal 108 results in an increased leakage flow rate. The sleeve 64 closely surrounds the shaft and is an extension of the cover 26 for the centrifugal pump casing 12. The shaft is journalled in bearings 72, 204 and 244. The seal 12 is a self-restoring non- contact face type seal and comprises a ring 110, Fig. 4, slidably mounted on a member 126 secured to the sleeve 64 and having a sealing face 132 urged by a spring 148 towards a cooperating face 134 on a runner 112 secured to the shaft. The ring 110 is sealed to the member 126 by an 0-ring 146 and has orificing means 136 between the space 137 and a position intermediate the gap between faces 132 and 134 which serves to maintain said gap and thus the leakage flow, constant. The seal 94 comprises a first sleeve 88 fixed to the shaft and surrounded by a second sleeve 96 secured to the sleeve 64, the sleeves 88 and 96 being separated by an annular gap 95. The fluid leaking through the seal 108 is prevented from contacting the motor by a back-up sealing ring 166 urged by a spring 168 into contact with a ring 118 on the shaft and is led to an external pipe 158 through passages 152, 154 and 156. If desired, a separate leakage flow circuit, which acts as a coolant when the pumped fluid is at a high temperature, may be provided. For this purpose relatively cool fluid at a pressure slightly higher than that in the pump casing is supplied to the clearance between the shaft and the sleeve 64 through a conduit 162 and a passage 160 in the cover 26. During normal operation the rate of fluid flow through the gap 95 of the seal 94 is such that the pressure drop across it is minimized and sealing effected by the seal 108. If, however, the latter fails the rate of fluid flow through the gap 95 increases and the seal 94 then operates to control the leakage rate. In modifications, the shaft is supported in two and four bearings respectively.

Title: Apparatus for detecting earth faults in electric current supply systems
IPC: H02H3/38
Filed: 1960-11-14
Abstract: 923,292. Protective cut-out systems. SIE. MENS-SCHUCKERTWERKE A.G. Nov. 14, 1960 [Nov. 13, 1959], No. 39113/60. Class 38 (5). An earth leakage protection system includes a core-balance transformer W having a secondary winding, the output of which is fed to means which responds to its phase relationship to a control value dependent upon the voltage relationship of a part of the protected system to a conductor extending alongside the main system conductors. As shown in Fig. 1, the relay R responds to the phase relationship between voltages Ust, U 1 , U 2 , the former being proportional to the voltage between an artificial star point and a " protective conductor " SL. In Fig. 3, the voltage Ust is arranged to oscillate a " mechanical contact rectifier" 1 so that the output U of the core-balance transformer is fed to a polarized relay 2 to effect operation in a direction dependent on the phase relationship and so indicate the direction of the fault relative to the transformer. A transistor bridge circuit may be triggered by the voltage Ust (Fig. 4, not shown), or the respective voltages may be converted to squarewave pulses and/or amplified to operate a relay which may cause the main system to be deenergized (e.g. by a short-circuiting switch, Figs. 5 and 6, not shown).

Title: Optical systems
IPC: B64F1/20
Filed: 1961-11-03
Abstract: 1,003,886. Beacon lights. SENDLINGE OPTISCHE GLASWERKE G.m.b.H. Nov. 3, 1961 [Nov. 4, 1960], No. 39392/61. Heading F4R. A lens for aerodrome lighting or like purposes for producing beams of light leaving the lens surface at a small angle of emergence comprises a glass body having a substantially flat outlet face and a hollow inlet face surrounding but spaced from the light source, the arrangement being such that a first part of the light passes direct to the outlet face and a second part is reflected and crosses the first part on the way to the outlet face. The glass body may be designed for omnidirectional or bidirectional lighting. In one form light from the source L is formed into a parallel beam by a convex toroidal ring 3 and is refracted at the emergent face 14 at a small angle, e.g. 3 degrees to the horizontal. A second part of the light passes through a frusto-conical ring 5, and after reflection at a surface 6 which may be plane or parabolic, crosses the first beam of light and is refracted at the emergent face 16 at a similar small angle. The emergent face may be plane or the central part 16 may be surrounded by a slightly inclined ring 14. Alternatively, the central part 16 may be in the form of a concave conical surface of small inclination. The surface of the block inside the ring 3 may be formed with concentric grooves so as to refract the incident light to emerge from the outlet face at a small angle. Light which is internally reflected at the outlet face may be reflected by a face 13, re-reflected at the outlet face so as to pass back through the source L being then reflected by a spherical mirror 18. The face 13 may be formed with grooves so that incident light is reflected in a parallel path. The face 5 may also be a convex toroidal ring so as to produce a parallel beam. The light source may be surrounded by a coloured shell 17. In a bidirectional block, the toroidal face or faces may be replaced by convex cylindrical lenses.
Patent GB-395625-A (GB)
Abstract: 395,625. Ticket-printing and totalizing machines. HANEL, C., 30, Lahnstrasse, Neuk÷lln, Berlin. Feb. 2,1933, No. 3206. Convention date, Feb. 2, 1932. [Class 106 (iii).] In apparatus in which counting-mechanism is operated during the rotation of a printing- cylinder in accordance with the range of movement of operating members associated with setting means for adjustable type wheels, the different operating members are moved once in succession during a complete revolution of the printing-cylinder and the counter is correspondingly rocked into and out of gear. Printing type wheels 7a .. 7d, rotatably mounted in the printing-cylinder 4, are adjusted independently from setting -levers 14a . 14d through toothed gearing and concentric shafts 10a .. 10d giving a 3 to 1 ratio. The setting levers are so mounted on a shaft 15 that they may all be moved axially by an operating knob 23. The spring 24 tends to move them towards the left so that lugs 17a .. 17d may engage gear wheels 12a .. 12d, each of which is in turn geared to one of the concentric shafts 10a .. 10d; but this movement can only take place with the drum 4 in the starting position, when a recess in a disc 20 geared to the drum is opposite a disc 19 on the shaft 15. When the setting levers have been adjusted, adjustment of -the shaft 15 towards the right moves them out of gear, as shown in Fig. 4, and they are then locked. The disc 19 is also moved out of the recess in the disc 20 so that the drum 4 may be turned by a handle to print and feed forward a strip ticket. During each revolution of the drum, the four operating members 28a .. 28d are rocked in succession about their pivot 27 so that a toothed sector on each member may engage its corresponding pinion 37a .. 37d on a counter 38 which is also synchronously rocked about its pivot 16, the pinions being held clear while the sectors swing to the left and engage on the return movement. The counter 38 is rocked in and out four times during each revolution of the drum by engagement of its nose piece 40 with a rotating cam 42 geared to the drum. The angle through which each operating member 28a .. 28d is rocked is determined by engagement of its nose piece 29 with a stepped cam such as 26a, each cam being adjusted by one of the setting levers 14a .. 14d. Each operating member is moved in one direction by a spring 35 and in the other by a stepped cam 34a .. 34d carried by a shaft 33 which passes freely through slots in the sectors and is geared to the drum 4, the cams being spaced round the shaft so that the quick movement to the left and the slower return of the members are carried out in succession.
