Title: Improvements in Metal Working Lathes.
IPC: B23B7/04
Filed: 1917-10-24
Abstract: 120,085. Craven Bros., Thomas, H. E. R., and Tams, F. G. Oct. 24, 1917 Lathes.-In a lathe comprising a single work-carrying spindle 25 and a vertical turret 150 with its axis parallel to the spindle axis and having a number of slotted planes or faces for the tools, the turret is slidably supported on a fixed cylinder 152 mounted in the machine frame, so that the cutting strains are borne by the cylinder during the longitudinal travel of the turret. The turret is reciprocated by a draw-bar 155 passing through the cylindrical support and provided with means for imparting an increased or reduced movement to the turret relatively to the movement of the drawbar. The increased movement is effected by providing the drawbar with a pinion 167 gearing with a fixed rack 168 on the support and with a rack 170 on the turret. The reduced movement is effected by arranging the fixed and movable racks on the same side of the pinion, and making the pinion a compound one of two diameters, the larger part meshing with the stationary rack, the smaller with the movable rack. The drawbar is actuated by cams on a cam drum 63. The turret is locked by a pin engaging a notched wheel on the turret, and when this pin is withdrawn by a lever actuated by a cam during the return sliding move. ment of the turret, a friction clutch on the worm shaft 219 is engaged and the shaft 219 rotated to drive the worm-wheel 222 on the turret. The locking and driving mechanism of the turret is movable with the turret along the support 152. The work spindle 25 is driven by the fast pulleys 36 or 39 and gearing 35, 26 or 40, 27 and clutch 28, so that four speeds may be given to the shaft. The belts are shifted on to the loose pulleys by shippers actuated by levers and a cam on a shaft 50 which is oscillated by adjustable cams 53, 54 on the drum 56. The bobbin 67 for operating the work chuck is reciprocated by cams 75, 76 through a slide 72 and lever 70. When the chuck is open, the work is fed forward by reciprocating grippers actuated bv a sliding member 69, which is operated by a cam 77 on the drum 63 through a lever 79, rod 81, and another sliding member engaging the member 69. The return movement of the grippers is effected by the drawbar 155, which is connected through adjustable links to the sliding member engaging the member 69. The adjustable connexion enables the feed of the work to be varied. The cam shaft 59 is driven by a pulley 87 through variable gears 89, 90, epicyclic gearing 93. 97, 99, a gear-wheel 100 driving the spindle 101 through pawl and ratchet, and a worm 106 engaging a worm-wheel on the shaft 59. A quick direct drive of the spindle 101 may be effected by engaging the clutch members 108, 109 by means of a lever 111 actuated by cams on the drum 56. The shaft 101 may be operated by a hand-wheel 112. The cutting-off tool 147 is carried by a lever 135 which is oscillated by a cam 145 on the drum 64. A second lever is oscillated by cams 142, 143, and actuates, through a rod 136, the forming slide 134.

Abstract: 1,114,362. Semiconductor devices INTERNATIONAL STANDARD ELECTRIC CORPORATION. 7 April, 1966 [22 April, 1965] No. 15567/66. Heading H1K. In a junction transistor having the emitter, base and collector regions extending to one surface of the body, the emitter region comprises a plurality of separate areas and the surface of the body is covered with an insulating layer having apertures through which the emitter areas and the areas of the base region between the emitter areas may be contacted by conductive layers. As shown, Figs. 1 and 2, a silicon dioxide masking layer 6 is thermally produced on the surface of an N-type silicon wafer 10, acceptor impurities are diffused-in to form P-type base region 2 which is substantially in the form of a square annulus, the oxide layer is reformed, and phosphorus is diffused in from a P 2 O 6  source to form a plurality of strip-like emitter areas 1. The oxide layer is reformed and strips are removed over each of the emitter areas 1 and over the areas of the base region lying between the emitter areas. Aluminium is deposited over the surface and masked and etched to form interdigitated emitter electrode 3 and base electrode 4. A plurality of such devices may be simultaneously produced in a single wafer which may be subdivided by scribing and breaking or by ultra-sonic machining. As shown in Fig. 2, collector region 10 extends to the surface of the wafer in the centre of the base region where it is covered by oxide layer 6 and the central part of the base electrode 4 to which a lead-wire may be bonded. This arrangement reduces the base-collector junction area and hence the base-collector capacitance. The capacitance between the central part of the collector region and the overlying base electrode 4 may be reduced by forming a screening region (not shown) of the same conductivity type as the base region below the oxide. This screening region may be left floating or may be provided with an electrode for biasing purposes. In a further embodiment, Fig. 3 (not shown), the base region is a circular annulus and the emitter areas are in the form of sectors. In a modification of this embodiment, Fig. 4 (not shown), each sector is divided into a plurality of curved strips. The base and emitter leads may comprise the inner and outer conductors respectively of a co-axial cable, the connections to the electrode layers being effected by means of pressure contacts.

Title: Synchronizing clutch
Inventor: KRON HAROLD O
IPC: F16D23/04
Filed: 1971-05-20
Abstract: 1277717 Synchronizing clutch KING OF PRUSSIA RESEARCH & DEVELOPMENT CORP 20 May 1971 15973/71 Headings F2C and F2L The drive for heavy marine or military installations or for synchronous condensers includes a multi-plate friction clutch 30 between an input (output) shaft 10 and an output (input) flange 20 to synchronize the engagement of a parallel positive clutch 40, the input member 42 and output member 22 of which carry equal numbers of external teeth 242, 25 which co-operate with proximity detectors 101, 100 to signal the approach of synchronism and to initiate engagement of the positive clutch. Engagement of the friction clutch is effected by closing a switch (SW1), Fig. 9 (not shown), which energizes a solenoid valve V2 provided the speed of shaft 10 is less than a predetermined value, e.g. 1100 r.p.m. If the speed exceeds this value, depression of an additional switch bypasses the open contacts of a relay (CR4). The clutch cannot be engaged when shaft 10 rotates above a second predetermined speed, e.g. 2200 r.p.m. when a second relay (CR5) will open. Energization of solenoid valve V2 connects the compressed air pressurized oil to a rotary coupling 82 which transmits the oil through axial tube 18 and radial bores 118 to the clutch actuating piston 32 to engage the clutch. When the speed at flange 20 approaches closely the speed of shaft 10, e.g. within 5-11 r.p.m., a third relay (CR3) operates to energize a solenoid valve V1 to connect the oil to a line 154 to slide a piston 51 and its tubular rod 50 to the right. The rod 50 acts on a push rod 17 which carries radial pins 116 passing through slots 312 in an extension 112 of a tube 12 keyed to the shaft 10. The pins push a gear 41 splined to the extension 112 to the right, the positive clutch input member 42 being helically splined on the gear 41 and initially moving therewith. When the teeth 242 on member 42 abut the cooperating clutch teeth 122 on member 22 continued movement of gear 41 to the right causes relative rotation between the gear 41 and member 42 to allow the teeth to move into intermeshing engagement, and ball detents 216 carried by a member 16 on the rod 17 hold the rod in its clutch engaged position. The friction clutch may then be disengaged. Wedges 52, 53 on piston-rod 50 prevent disengagement of the positive clutch under torque reversal. To disengage the clutch 40, a switch (SW0) is opened to de-energize the solenoid V1 and energize a solenoid V4 to re-connect the oil pressure to line 155 to withdraw the piston 50 and open limit switch (LS1) to de-energize solenoid V2 and disengage the friction clutch. On opening switch (SW0), a disc brake 19 acting on shaft 10 is also applied by compressed air acting on pistons 91, 92 through a solenoid valve V3. The circuit of Fig. 9 also includes signal lamps for friction clutch engagement, approach of synchronism, positive clutch engagement and disengagement, and brake engagement. The clutch teeth and plates are oil cooled.
