Title: Improvements in or relating to alternating current generators
IPC: H02K11/04
Filed: 1981-03-27
Abstract: An alternating current generator, particularly a three-phase generator for motor vehicles and the like, is proposed in which, after a recess in the slip ring casing (bearing frame) for installation of the stator assembly including the end turns of its winding, the diameter of the slip-ring casing is reduced, thereby resulting in a slip-ring casing having a triple stepped configuration; the printed circuit board and diode heat sinks are located in the mid region of intermediate diameter of the casing. The rotor shaft bearing is located in the central inner region of the smallest diameter part. The casing has ventilation openings disposed in the region interconnecting the central inner region and the annular wall of the region of intermediate diameter. <IMAGE>

Title: Sealing means
Inventor: HARBIDGE JOHN
IPC: F16J15/56
Filed: 1982-02-16
Abstract: Sealing means for relatively slidable members such as a piston (2) and cylinder (3) consists of a sealing member or ring (1) (e.g. of PTFE) in a groove (21) which is urged in axial and radial directions by resilient means shown in the form of an O-ring (4) of rubber or the like acting against an inclined rear end of the ring (1). The rear end is provided with a trailing lip (10) for low pressure sealing with minimum friction under the action of fluid under pressure acting on said end of the ring (1). The ring (1) is also arranged to be acted upon by fluid under pressure ducted radially (22) into the groove (21 at 214) for radially and axially thrusting the ring (1) for high pressure sealing. The forward end (12) of the ring (1) is inclined for co-operation with an inclined end (212) of the groove (21) whereby the ring (1) is thrust radially in the sealing direction. A forward member (11) of metal or other suitable hard material is provided at the forward end of the ring (1) either bonded to it or separate therefrom and is for preventing extrusion of the ring (1) between the piston (2) and cylinder bore (30) under conditions of high fluid pressure. In alternative embodiments the forward member 11 is differently shaped. <IMAGE>

Title: Threading head for a numerically controlled multiple spindlehead indexing machine tool
Inventor: KIELMA ERVIN J
IPC: B23G1/02
Filed: 1983-02-16
Abstract: A threading head for use on a numerically controlled multiple spindlehead machine tool includes a frame 12 having a hollow bore spindle 16 journaled therein so that the spindle extends therebeyond. The spindle is helically advanced out from and is retracted into the frame by the combination of a ball nut and a ball screw disposed between the spindle and the frame. The helical movement of the spindle is precisely controlled by a first servo-controlled motor 35 which rotatably drives the ball screw in response to numerical control commands. A cross block cutting tool 60 is slidably mounted on the face of the spindle distal from the frame and is displaced radially across the spindle face by a screw 44 journaled in the spindle perpendicular to the axis of the spindle so as to threadedly engage the cross block cutting tool, the screw being driven by a second servo controlled driver motor 54. Thus, by controlling the excitation of each of the two servo controlled drive motors, the length of the threads chased, the speed at which such threads are chased and the depth of threads cut can be controlled accordingly. <IMAGE>

Patent GB-2140990-A (GB)
Title: Water heaters
Inventor: LEWIS ROBERT
IPC: F24H9/20
Filed: 1984-05-09
Abstract: A water heater of the kind in which flowing water is heated by electric heating elements has a first heating element 7 and a second heating element 8 which are in series. When a triac switch 16 is conductive electricity from a mains supply L, N passes through them and heat is generated by the elements. When another triac switch 12 is also conductive electricity from the supply passes through the first heating element 7 but not through the second 8 so that the total resistance is less and the heat output is increased. Additional heating elements 9, 10 with an associated triac switch 13 may act in a similar manner. The heating elements may be bare wire coils extending along a water passageway and some may be subdivided into portions spaced apart to reduce any tendency to momentary temperature variations in the heated water when switching occurs (Fig. 4). The resistances of elements 7 to 11 may be arranged so that by operating various combinations of triacs 12, 13, 14, 16 the heat output may be increased from a base level to a maximum level in seven equal increments. The triacs may be under manual or thermostatic control. Alternatively, a microprocessor (21), (Figure 5), may control the triacs, a solenoid water flow valve (24) and an indicator (31) in response to inputs from manual selectors (27 to 30), or temperature sensor (25), and a switch (26) responsive to absence of water flow. <IMAGE>

Abstract: A system for controlling an elevator includes a motor 15 having a three phase high speed winding 15a and a multipolar single phase winding 15b. The motor 5 controls an elevator cage 3 and counterweight 4 via a winch 1 and cable 2. A brake 7 is also provided. The elevator control circuit includes three terminals 9R, 9S, 9T which are connected to a three phase power supply and to the high speed winding 15a via three lines which include rated speed contactors 16a, 16b, 16c. Two of these lines include ascent contactors 12a, 12b and descent contactors 13a, 13b.
