Abstract: 1,260,062. Control systems for starting and running prime movers. GENERAL MOTORS CORP. 30 July, 1970 [4 Aug., 1969], No. 36909/70. Heading H2H. A motor vehicle having an I.C. engine and a fuel pump is provided with an electrical control circuit which is arranged to control the pump so that the fuel delivered thereby is at a lower rate when the engine is operating at low speeds than that when the engine is operating at high speeds. The electrical control circuit is provided with an ignition switch 14 having contacts 34-44 and four operative positions, the switch positions and contact settings being tabulated in Fig. 2 of the drawings. At starting the contacts 40, 42, 44 close thus the positive battery feed 56 supplies the ignition circuit over contact 40, the engine cranking means over contact 42 and the fuel pump 10 over contact 44. Closure of contact 40 also causes a generator tell-tale lamp 120 to be illuminated by way of normally closed contacts 122, 118 in a voltage regulator assembly 76. When the engine is running the switch 14 is returned to the ON position in which contacts 38, 40 are closed. The output of the alternator/rectifier, assembly 74 appears on line 102 to charge the battery 12 and to energize line 56. The relay coil is energized from a terminal 131 in the rectifier bridge 88 to close contacts 122, 120. The output voltage of the assembly 74 then appears on both terminals of the lamp 20 which extinguishes. With the engine running a switch 24, operated by the engine oil. pressure, closes to energize the fuel pump 10 by way of a network 48. At low throttle settings a switch 64 remains open so that the pump 10 is energized over a resistor 62 so that the fuel delivery rate is low. At high throttle settings the switch 64 closes whereby the pump 10 is fully energized to give a high fuel delivery rate. During starting with a flooded engine, a high throttle setting opens a switch 50 so de-energizing the pump 10 to assist starting. The voltage of the alternator 80 is regulated by the contacts 110, 112, 114 of a relay 108 and a resistor 124. The tell-tale network 22 includes two further lamps 140, 142, the lamp 140 indicating a cold engine and being energized by means of a bimetal switch 146, the lamp 142 indicates an overheated engine Accessory loads 26-32 are supplied over contact 38.

Filed: 1959-11-03
Abstract: 875,251. Tiles &c. BRAX, E. K. Nov. 3, 1959, No. 37198/59. Class 87(1) A wall cladding unit, such as a tile, has on two opposed edges, formations which interlock with formations on the adjacent edge of an adjacent similar tile, each such edge being formed with a groove, 4 or 8, and a lip 5 or 9, so that at each interlocked joint there are two lips engaged in two grooves. When the interlocking formations are engaged with each other, the units must first be in inclined positions relative to each other and then brought into co-planar relationship. In the form shown, a step 11 on a portion of one unit extending beneath the other unit, locks the units together in a direction parallel to the surface to which the units are applied. In a modification, Fig. 2 (not shown) one of the two units has a lip of curved crosssection received in a complementary groove in the edge of the other unit whereby the units are locked together in the direction parallel to the supporting surface. The units are secured to the supporting surface by fastening means 12.

Abstract: 1340990 Lubricating PENNWALT CORP 9 Aug 1972 [16 Aug 1971] 37213/72 Heading F2A A lubricating system for lubricating the bearings 18 of a vertical rotor 10 on the start of rotation comprises two members 34, 44 secured to the rotor, one member 34 having an inwardly facing pocket and the other 44 having an upwardly facing pocket, the arrangement being such that during rotation lubricant is retained in the inwardly facing pocket by centrifugal action but on cessation of rotation the lubricant drains into the upwardly facing pocket from which it is thrown on the start of rotation to lubricate the bearings. Lubricant may be supplied during the rotation of the rotor by a pump 14 which is driven by the rotor. The upwardly facing pocket may be divided into a number of segments to reduce lubricant loss if the rotor is not precisely vertical. The pockets may be above or below the bearings to be lubricated.

[Also in Group XXVIII] A penetrable sealing closure 17 (see Group XXVIII) comprises two resilient, elastomeric, superposed members 31, 32 having openings which, with the members in normal position, are out of alignment so that the closure is rendered air-tight by superposed substantially flat surfaces on the members, the members being capable of distortion, by insertion of a tube 20 through the opening in one member to bring the openings into alignment to permit the tube to be pushed through the openings, thereby penetrating the closure. As shown, the closure is mounted in the mask 16 of an airman's helmet 15 to permit passage of a tube to the wearer to permit him to eat, drink, smoke, or to permit the admission of a further air supply in case of emergency. A cigarette or cigar holder 52 comprises a rigid tube 20, Fig. 10, of metal or plastic having a bore therein extending from the mouth portion 20a to an enlarged end portion 20d which receives the cigarette 48. A centrally apertured partition 49 of hard rubber or rigid plastic provides an annular seating surface 49a for a corrosion-resistant metal sphere 51. A compression spring 53, one end of which abuts a hard rubber apertured member 50 urges the valve 51 against the seating. This arrangement prevents the release of internal fluid pressure from within the helmet when the end portion 20a is not within the wearer's mouth but permits the flow of smoko to the wearer.

Abstract: 1,153,896. Grinding. ETABS SIM S.A. 30 Aug., 1966 [1 Sept., 19651, No. 38577/66. Heading B3D. A machine for simultaneously face grinding the end surfaces of one or more rotating members 4 comprises two coaxial grinding discs 1 and one guide disc 2 laterally overlapped by the grinding discs and parallel thereto, the outer surface of the guide disc at least in the region which is overlapped by the grinding discs, and the inner surface of an outer coaxial annular section 3 defining a guiding channel for one or more of the rotating members, the annular section and the guide disc being rotatable relative to one another in such a manner that a rotating member in the guiding channel centra-rotates to the direction of the grinding disc and is also rotated about its own axis. The grinding wheels 1 rotate about a horizontal axis in the same horizontal plane as the axis of rotation of the guide disc 2 which is coaxial with the annular section 3. The inner surface of the annular section is formed with a groove containing a rubber or synthetic material member 5, Fig. 2, adapted to press the rotating members 4 against the outer surface of the guide disc as the latter rotates. The rotation of the guide disc is in the direction of arrow c so that the members 4 rotate in the direction d, which is opposite to the direction a of rotation of the grinding wheels. The rotating members are supplied to the guide disc from a channel 10 and a geared wheel 11 and are constrained in the axial direction by a control plate 7, Fig. 2, which is spring loaded and urges the members against an adjustably fixed plate 6. In another embodiment, the disc 2 is stationary and the section 3 is circular and driven in the same direction as the grinding wheels. In a further embodiment, the member 5 is located in a groove in the guide disc 2. In yet another embodiment, the grinding discs rotate about a vertical axis, and in a final embodiment, the section 3 extends over a full circumference so that the members 4 to be ground can effect several passes between the grinding wheels and are supplied radially or laterally to the guide channel.
