Title: Improvements in or relating to multi-spindle drilling machines
IPC: B23B39/16
Filed: 1935-01-21
Abstract: 430,405. Drilling - machines. MAIN, Ltd., R. & A., 48, Grosvenor Gardens, Bucking- ham Palace Road, and STUTELY, W. H., Gothic Works, Edmonton, both in London. Jan. 21, 1935, No. 1990. [Class 83 (iii)] A multiple-spindle drilling-machine of the vertical-standard type has an overhead bearing block in which the parallel spindles are rotatably mounted and driven by a single transverse worm shaft which engages worm teeth on the spindles, the latter being supported in bearings above and below the worm teeth and having thrust blocks at their upper ends. The vertical standard 44 supports a block 11, Fig. 3, and brackets 16, 17 secured to this block carry the drilling spindles 23; these are provided with adjustable thrust races 32 and the drills are guided in a fixed jig-plate 47. Each drill spindle has formed integral with it a small worm wheel 24 and these are all engaged by a single worm 40 on a transverse belt driven shaft 37. The latter drives through worm gearing a vertical shaft 64 which in turn drives through pick-off gears a transverse cam shaft 61 ; this shaft may also be turned by hand. A cam 59 on the end of the shaft engages a roller on a bracket attached to a vertically slidable work table 49 for the work feed movement. The bracket also carries an adjustable bolt 58 which when moved upwardly serves to close the jaws of a work-holding device, (not shown), further upward movement when the jaws are closed over the work giving upward feed movement to the table, when no work is present the table does not rise.

Filed: 1937-01-21
Abstract: 477,071. Automatic control systems. JOHNSTON, F., and REBBECK, F. E. Jan. 23, 1937, No. 2054. [Class 38 (iv)] [Also in Group XXXVIII] Steering.-In a Wheatstone bridge control system for steering ships comprising control and follower resistances 2, 9 which effect, through a Ward-Leonard system 15-18; the control of the rudder motor 13, additional means are provided for effecting automatic steering under the control of the compass. The compass needle 40 operates between two pairs of contacts 34, 39 connected respectively to relays 26, 27 which are arranged to shortcircuit parts A, B of the control resistance. Alternatively, the relays may short-circuit parts of the follower resistance. When the system is arranged for automatic steering, the contacts 5, 9 of the resistances occupy central positions and upon any deviation of the ship from the set course, the compass needle 40 short-circuits one or other section A, B to unbalance the bridge and thereby effect control of the rudder motor 13 until the ship is returned to its course.

Title: Tape transport device for tape recording and/or reproducing apparatus
IPC: G11B15/44
Filed: 1974-01-17
Abstract: 1425668 Hydraulic couplings SONY CORP 17 Jan 1974 [19 Jan 1973 (2)] 2308/74 Heading F2W [Also in Division G5] A fluid coupling in the drive to the reels of a tape recorder comprises a drum driving member 83 coupled via the fluid in cylindrical cavity 85 within the drum to a disc driven member 84 connected to drive shaft 80. The shaft rests on a bimetallic plate 94 in the cavity base which acts during increase in temperature to move the driven member upwards to reduce the distance between it and the roof of the cavity in the driving member thus compensating the reduction in torque transmission due to the drop in the viscosity of the fluid. In a second arrangement Fig. 9 (not shown) the bimetallic plate is dispensed with and the driven member is formed of bimetallic material. In the Fig. 10 arrangement plunger 114 is vertically displaced downwards by screw jack 119 when the recorder is changed from normal to fast forward mode thus the take up reel drive shaft 96 is lowered by arm 110 thereby increasing the distance between the driven disc 102 and the roof of the cavity in the driving member. This movement decreases the coupling to reduce the torque transmission to protect the tape when the supply reel completely unwinds. In this arrangement the arm 110 can be of bimetallic material.

Title: Linear superpolyester production
IPC: C08G63/85
Filed: 1964-01-23
Abstract: A linear polyester is produced by solid phase polymerization of particles of a prepolymer of a glycol and a dicarboxylic acid in a stream of dry air or inert gas of atmospheric pressure and in the presence of an Sb or Mn catalyst.  Glycols specified are ethylene, butylenes, pentylene and neopentylene glycols, 1,4-di-(hydroxymethyl) cyclohexane 2,2,4,4 - tetramethylcyclobutane - 1,3 - diol and polybutylene glycol. 50% or more of the dicarboxylic acid may be an acid comprising 2 carboxyl groups directly linked to a hexacarbocyclic nucleus, e.g. terephthalic acid, naphthalene-2,6-dicarboxylic acid or diphenyl sulphone-4,41-dicarboxylic acid.  The remainder may be dimethyl malonic, succinic or adipic acid.  The catalyst may be 0.01-0.5% Sb2O3 and 0.005-0.2% manganous acetate in the ratio 30:1-600.  The reaction may be carried out in a polymerization zone, 5% or more of which is occupied by prepolymer particles having an inherent viscosity of 0.1-0.45, all the particles being capable of passing through a 20-mesh screen and less than 25% passing through a 200 mesh screen.  The reaction may be at 175-300 DEG  C. and the particles may be in a static bed 0.5 mm. thick or may be agitated by the gas stream, by stirring or in a tube of corrugated cross-section inclined to the horizontal and rotated about its longitudinal axis.  The inert gas may be N2, CO2, He, propane or dried burned natural gas containing no more than 0.1% CO. 10-1000 ml./min./g. of particles may be used.  The exhaust gas may be recycled.  The product may be made into fibres, films or shaped articles.  In Example (1) dimethyl terephthalate and 1,4-di-(hydroxymethyl) cyclohexane were reacted in a N2/CO2 mixture containing less than 2% O2 to give prepolymer particles suitable for further polymerization.

Abstract: 347,708. Stabilizing aircraft automatically. TARBOX SAFETY AIRCRAFT CO., 5025, Schuyler Street, Germantown, Pennsylvania, U.S.A.- (Assignees of Tarbox, J. P. ; 5025, Schuyler Street, Germantown, Pennsylvania, U.S.A.) Jan. 28, 1930, No. 2925. Convention date, Jan. 29, 1929. [Class 4.] The lateral balance of an aircraft is preserved by pilot vanes on each side of the machine and a standard of position such as a pendulum acting differentially upon the aileron controls. As shown, two laterally disposed vanes 12 are pivoted about forwardly convergent horizontal axes 13 so that the incidence of the vanes diminishes as they rise and increases as they fall. The movements of the vanes apply pressure through levers 15 to variable resistances 16 in circuit with a battery 26. A pendulum 18 having a vane 20 responsive to lateral pressures, is pivoted about a longitudinal axis 19 and its movements control variable resistances 21 in a second circuit including the battery 26, the centre points 27, 28 of the two circuits being connected to an instrument 29 to form a Wheatstone's bridge. This instrument may be manually adjusted about a vertical axis 30. The indicating arm 35 of the instrument co-operates with two contacts 33, 34 on a ring 32 to control a reversible motor 37 which turns a drum 40 to move an aileron cable 42. This cable is divided and wound part way around the ring 32 so as to constitute a followup device. Instead of acting to unbalance a Wheatstone's bridge, the vanes and pendulum may act mechanically upon two differentially moving levers controlling the motor control contacts. The vanes 12 are so chosen that their change of lift per unit change in the angle of incidence is greater than the corresponding change of lift of the main planes, and the inertia of the vanes and connections is kept as small as possible.
