A lathe or like machine tool having a turret, comprises a system for automatically controlling the machining operations, which includes a series of manually-settable electric switches associated with each face of the turret, each series being connected to a control circuit when its turret face is in the operative position. A turret lathe, Fig. 1, comprises a tool turret 22 mounted on a slide 21, a headstock spindle 24, and a cross-slide 25 mounted on a saddle 26, and having a front and rear tool post FTP and BTP. Cross-slide 25 is operated by two pneumatic rams 200, 203, associated with hydrocheck units 205, slide 21 is operated by a pneumatic ram, 211 associated with a two-speed hydrocheck unit 212, a pneumatic jack 315 operates a lever 32 to actuate the collets, a forward and reverse lever 27 for the headstock is operated by a pneumatic ram 322, a fast and slow clutch lever 28 is operated by a pneumatic jack 343, a feed change lever 29 operated by two pneumatic jacks 325, 326, and a fine and coarse feed lever 342a is operated by a pneumatic jack 342.

Title: Active filter capacitor circuit

Filed: 1971-11-24
Abstract: 1354590 Smoothing direct current INTERNATIONAL BUSINESS MACHINES CORP 24 Nov 1971 [21 Dec 1970] 54513/71 Heading H2F [Also in Division H3] An active capacitor circuit for smoothing a D.C. power supply voltage comprises at least one transistor T1 having its emitter and collector connected to a pair of terminals for connection across the power supply and an input supplied from the output of an amplifier 10, supplied from said terminals via a resistive divider and having negative feedback, so as to have a low D.C. gain and high A.C. gain. As described, amplifier 10 has unity gain for D.C. and increased gain for A.C. due to capacitor Cl in the feedback path. The D.C. gain biases T1 so that it may conduct bi-directional ripple current. Any increase in voltage at A (due to ripple or load fluctuation) is amplified by amplifier 10 and causes increased current to be taken by T1 and hence increase voltage drop across inductor L so as to compensate for the increase voltage. In Fig. 4 (not shown) a blocking capacitor is inserted in place of resistor R2 and a separate bias circuit provided for T1. In Fig. 7, a complementary pair of transistors T2, T3 are operated in push-pull, biased by diodes D1, D2 to linear parts of their characteristics.

Title: Pile driver
IPC: E02D7/28
Filed: 1973-11-28
Abstract: 1452777 Pile drivers BOLT ASSOCIATES Inc 28 Nov 1973 [28 Nov 1972] 55270/73 Heading B3H [Also in Division E1] A gas discharge powered pile driver comprises an airgun 16 which discharges high pressure gas into a chamber 30 defined by a cylindrical wall 28 whose lower end is closed by an impulse transmitting block 52. The airgun 16 and the wall 28 are mounted on the lower end of a massive weight 12 slidably mounted in a cylindrical housing 14. The block 52 is fixed to the lower end of the housing and mountable on a pile 15. In operation the chamber 30 is filled with water supplied through a bore 74 in the weight. The airgun discharge into the water causes a force to be transmitted through the block 52 to the pile and causes the weight 12 and associated airgun 16 and wall 28 to raise. The block 52 has a tubular extension 56 around the wall 28 and the chamber 30 increases in volume but remains sealed until the lower end of the wall reaches a tapered region 58 of the extension 56. The pressure is then released through the gap 138, Fig. 5, and the weight descends. The wall 28 impacts with a groove 130 on the block 52 to cause a second force on the pile. Thus the pile is driven twice for each discharge of the airgun. The groove 130 fills with water to provide a cushion for the impact. The airgun recycles automatically or is fired manually. The airgun may operate with compressed air, steam or gaseous combustion products. The pile driver is particularly suited for underwater operation and is suspended from a crane by a chain 68, Fig. 7. The water, air and electric supply to the airgun 16 and chamber 30 is provided by pipes and wires 18A, 70A, 104 connected to an extension tube 80 of the weight bore 74. The wires and pipes have an accumulation loop to permit the weight movement. Alternatively the extension tube 80 is telescoped in a water sleeve (80A), Fig. 10 (not shown), at the top of the housing 14. The pile driver can be used inside a hollow pile (15), Fig. 12 (not shown), underwater. The driver engages a shoulder (188) welded inside the pile.

Abstract: 1489097 Motion sensitive infrared detector MINNESOTA MINING & Mfg CO 31 Dec 1974 [2 Jan 1974] 56170/74 Heading G1A [Also in Division H1] A detector 1 of the motion of a source of infrared comprises a front wall 3 with radiation transmissive apertures 8, a back wall 7 with inner, 13, and outer, 14, conductive layers with poled pyroelectric material, 15, between, said inner layer being nearest to wall 3, one of the conductive layers having one or more sets of electrically connected - sets of fingers 11, 12, parallel to the apertures, part of one conductive layer being earthed, layer 13 having areas that are simultaneously heated by and areas that are shielded from radiation through the apertures from the source, the material 15 being heated by the heated areas, so that electrostatic charges form on it and on one or more sets of fingers in contact with it, to which a circuit is connected to develop an alarm triggering signal for a predetermined sequence of voltage potentials in a predetermined period. Layer 15 is of polyvinylidene fluoride or a ceramic plate of lanthanummodified lead zirconate-titanate. The interdigitated finger sets 11, 12 are formed by etching wall 7, their width being “ of the distance between walls 3 and 7, so that a radiation source will be in line of sight with only one finger at a time. The etch width should be at least the thickness of layer 15 for correct heat distribution. Leads 16 connect the fingers to a circuit which may be on the back of detector 1 or remote. A differential amplifier (17), Fig. 5 (not shown), feeds full-wave rectifier (18), voltage amplifier (19) and Schmitt trigger (20). In a stable temperature environment one finger set, amplifier (17) and rectifier (18) may be omitted. On receiving say three pulses within a certain time counter (21) delivers an actuating pulse to alarm (22). Otherwise it resets. In an alternative embodiment the back conductive layer of wall 7 is fingered and the front layer. is the earthed conductor, which shields from electrostatic charges.

By positioning a slot and bore of a respective die member sufficiently close together each mesh member may comprise a dual strand which although is formed of two contiguous or coalesced strands is such that the separate identities of the component strands can still be discerned. A crossing point of a pair of dual strands produces four intersection points, i.e. A/A; A/B; B/A; B/B see Figs. 17, 18, not shown. The bores B may have a circular or rectangular cross-section. In the latter case the member 1 or 2 may be formed of two parts. The strands of the netting may be orientated by stretching.

Plastics material may be present between the islands. Two electrodes each having a terminal may be deposited on substrate 13, providing a voltage divider, or electrode 12 may be shaped to give a particular capacitance curve. To increase the capacitance a further electrode may be deposited on the opposite side of substrate 13 with its dielectric coating and conductive islands (Fig. 7, not shown) and a second associated wiper assembly. The two wipers may rotate in opposite directions or out of phase, the latter arrangement again providing a voltage divider. Substrate 13 may be alumina and dielectric film 16 a barium titanate glass. Alternatively if electrode 12 is tantalum, the dielectric may be tantalum oxide formed by surface xoidation. Electride 12 may be semi-conductive barium titanate and the dielectric an oxidized surface region. The substrate itself may be semiconducting or conducting.
