Title: Steady rest structure in a boring machine
IPC: B23Q1/76
Filed: 1957-11-13
Abstract: 872,606. Boring-machines. LEBLOND MACHINE TOOL CO., R. K. Nov. 13, 1957 [April 17, 1957], No. 35337/57. Class 83 (3). A boring-machine comprises a plurality of pairs of motor-operated arms 36 for supporting the boring bar 24, each pair being pivotally Mounted on a base 46, the bases being individually adjustable. A tail-stock 18 can be moved to clamp the work 22 against the headstock spindle 12. The non-rotating bar 24 is carried on a slide 26 moved by a motor 28. Coolant passes through a pipe 30 into the tailstock 18, around the head of the bar, through a bore into the bar, and thence to a velocity reducer 34. The bases 46 are bolted to a bracket 38 attached by bolts 40 to the machine frame. Each pair of arms 54, 56 has a stop 60 and an adjusting screw 62 to determine the pressure on the bar 24, the position of the arms being determined by an adjustable stop-screw 68. A chain 78 is attached to the arm 54 and passes over a pulley 74 on the arm 56. It is pulled to close the arms by a cam 86 rotated at a speed controlled by a valve 102 by a fluid-pressure rotary motor acting against a torsion opening spring 66. Each motor is operated by a projection 120 on the slide 26 which engages arms 116, 118 on a snap-over valve 104 so that, as the slide advances, the arms are opened and, as it is retracted, the arms close. In a modification, the arms are operated by pivoted cylinder-and-piston devices and all the arms are re-closed only when the slide is completely retracted.

Abstract: 829,024. S.T. measuring displacement. BRUSH ELECTRICAL ENGINEERING CO. Ltd. Oct. 29, 1957 [Nov. 20, 1956], No. 35474/56. Class 40 (1). [Also in Group XL (b)] In a system for measuring the linear or angular displacement of a movable member, e.g. a machine tool member, the displacement is measured using diffraction gratings arranged as indicated in Fig. 1, light from a suitable source passes through the two horizontal gratings B and A and the two circular gratings B and A fixed to the periphery of the scanning drum to illuminate the two photo-cells B and A. The scanning drum is driven at constant speed by the motor mounted above it. With the exception of the horizontal grating A which is fixed to the machine bed the equipment is mounted on the movable member of the machine. Sine wave voltages are developed at the output of the photo-cell circuits, the voltage of cell B is of constant frequency and the frequency of voltage A varies as the machine member is moved, hence altering the phase relationship between these voltages. The voltage Vb designated the primary reference voltage is squared and provides four positive control pulses A, B, C and D during each cycle, these voltages control the first four AND gates in Fig. 4. The voltage Va is squared and differentiated and applied to the other input of the four gates. Positive Va pulses coincident with control pulses A and C provide a count in the register, the coincidence of the Va pulses with control pulses B and D operates the sensing circuit FF2 to determine whether the count shall be additive, corresponding to movement in one direction or substractive corresponding to movement in the opposite direction. Fig. 7 (not shown) indicates an arrangement of gratings for measuring displacement in two directions. In an arrangement, Fig. 5, for producing correspondence control, the sine wave reference voltage Vb is applied via a sine-cosine resolver to a phase comparator where its phase is compared with that of sine wave voltage Va, any difference, which can be introduced by rotating the resolver shaft produces an error signal to drive the machine member, cancellation of the error is produced by the resulting phase change of voltage Va. A further arrangement (Fig. 6, not shown) describes the control of the machine member by signals received from a tape reader.

Abstract: 1278018 Fluid-pressure servomotor systems INSTITUTE FRANCAIS DU PETROLES DES CARBURANTS ET LUBRIFIANTS 22 July 1970 35551/70 Heading G3P [Also in Division G4] Apparatus for transmitting measured values of parameters of a drilling operation from the bottom of a well to the ground surfaces in the form of pressure pulses through the drilling fluid comprises a valve 25 located in the flow path of the drilling fluid and controlled by another fluid (e.g. oil) which is kept under pressure at 70 by means of pump 60 operated by a turbine driven by the flow of drilling fluid, the control fluid being released to operate valve 25 in response to electric signals derived from the measured values. The pressure pulses are converted at ground level to electric signals representing the measured values. The device shown is carried at the lower end of a drill string, the housing 20 also enclosing an alternator driven by the turbine and electronic means for converting values measured by sensors into electric signals, Fig .2 (not shown). The electric signals are applied at 53, 54 to electromagnetic slide valve 50 comprising an armature 52 connected to a valve body 44 which can move between valve seats in elements 48 and 49. When the valve body is in its lower position, oil under pressure in storage chambers 70 communicates through ducts 66, 47, chamber 43, and ducts 42 with housing 41, lifting valve 25 towards its seat 24, and producing pressure fluctuations in the drilling fluid. When no current is passing through the electromagnetic valve 50, the valve body 44 is in its upper position and the housing 41 communicates with pump 60 which returns oil to the storage chambers 70.

Filed: 1935-12-23
Abstract: 467,832. Fluid pressure brakes. WESTINGHOUSE BRAKE & SIGNAL CO., Ltd. Dec. 23, 1935, No. 35580. Convention date, July 11. [Class 103 (i)] A valve adapted to maintain automatically a desired pressure in a brake cylinder or other device and comprising exhaust and inlet valves 13, 14 controlled by diaphragms 10, 11 subject to a control pressure and the pressure in the brake cylinder is subject to a further control due to the action of fluid at a pressure dependent on the control pressure but modified in accordance with any desired variable condition such as speed or load. Control pressure is supplied from a triple valve 2 to a chamber 7 of a control valve 6 above the diaphragm 10 and the diaphragms 10, 11 and valves 13, 14 are thereupon depressed and the inlet valve 14 opened to connect the reservoir 4 to the brake cylinder 15 the pressure in which acting below the diaphragm 11 recloses the inlet valve when the desired pressure has been attained in the brake cylinder. The valve 6 is also influenced by the pressure fluid in a chamber 29 above a diaphragm 9 connected to the diaphragms 10, 11. This fluid is supplied from the triple valve 2 through a valve 37 operated by a centrifugal mechanism 5 driven from the vehicle axle. The pressure developed in the brake cylinder is thus dependent on the speed of the vehicle. The valve 37 is constructed similarly to the valve 6. In a modification the fluid supplied to the chamber 29 passes from the triple valve 2 through a valve constructed similarly to the valves 6, 37 but operated by hand according to the load on the vehicle. In a further modification this valve is operated by a diaphragm subject to the pressure of a column of liquid dependent on the liquid load in a vehicle such as a locomotive tender. This arrangement may be modified by supplying a second brake cylinder from the first through a speed-controlled valve. In a further modification two valves 6 are arranged in series the first supplying fluid to control the second which supplies fluid to the brake cylinder. The first valve 6 is influenced by a liquid load controlled valve and the second valve 6 is controlled by a speed controlled valve.

Title: Apparatus for detecting aquatic animals
IPC: A01K79/02
Filed: 1971-07-30
Abstract: 1318163 Fishing J D RICHARD 30 July 1971 [7 Aug 1970] 35920/71 Heading A1A [Also in Divisions H1 H3 and H5] Shrimps or other aquatic animals are detected by towing an instrumented vehicle through the water, periodically discharging electric current through the water via electrodes carried by the vehicle, thereby providing a stimulus causing the animals to move, and detecting such movement from the Doppler frequency shift of ultrasonic energy reflected by the animals. In the Fig. 2b embodiment the vehicle is a sled-like structure towed by a ship or helicopter and trails outer electrode pairs 11, 12 and inner electrode pairs 14, 15 (or the structure may serve as an electrode). A housing 4 includes pulse generator 6 for energising the electrodes, circuits for the continuous wave energisation of ultrasonic transmitting transducers 7, and circuits for detecting the Doppler difference frequency from signals received by transducers 8. The Doppler signal is recorded in the vehicle, or is fed via towing cable 62 (or via an acoustic or ionic conduction data link) to the towing vessel for analysis or indication. One indicating method (Fig. 2a, not shown) is to amplify the Doppler signal to drive a loudspeaker; and to trigger a monostable with the amplified signal if it exceeds a threshold amplitude and then integrate the monostable output to provide a voltage representing Doppler frequency, which voltage is recorded versus elapsed time and is also used to trip a counter. Another method (Fig. 5, not shown) is to pass the Doppler signal through a high pass filter (to distinguish shrimps, by their faster movement and hence higher Doppler frequencies, from other fish), and use the filtered signal to trip a relay for actuating an event recorder. Circuit details (Fig. 9):- Unijunction transistor oscillator 64 periodically triggers SCR 69 to discharge capacitors 67, 68 through the water between electrode pairs 11, 12, 14, 15 selected by mercury switches 70, 71. The SCR is switched off by L-C network 70 to end each brief conduction period. Diodes 66 protect the unijunction transistor from excessive voltage pulses developed on the SCR gate electrode during the discharge cycle. Transducer details (Figs. 10a, 10b):-The transducer elements 7, 8 are radial-mode piezoelectric cylinders stacked on tubular support 78 together with resilient spacers 82, resilient seals 84, plastic spacers 83 and metal baffles 9 (which block direct transmission between transmitting and receiving transducers). Upper and lower reflector wedges 88, 89 restrict the ultrasonic beams to a generally horizontal plane. Alternatively the transducer elements may be flat or curved plates operating in the thickness mode.

Abstract: 805,169. Door operating devices. DEANS & SON (YORKSHIRE), Ltd. Nov. 27, 1956, No. 36172/56. Class 65(1) A door is operated by remote control the arrangement being such that once the door has started to move towards its open or closed positions it will, if it fails to reach one of these positions in the normal opening or closing time, automatically return to its starting position. Fig. 1 shows the motor circuit and Fig. 2 the control circuit, all contacts being shown in the position occupied when the door is closed. To open the door the switch contacts 23 are broken, deenergizing the coil 61 to reverse the contact 6 and thus energize the coil 21 to reverse contacts 2 to energize the field coil 4 so that the motor opens the door; as the door begins to move it closes the contacts 32. When the fully open position is reached the contacts 22 are opened to de-energize coil 21 and stop the motor. To close the door, contacts 33 are made to energize coil 61 to reverse contacts 6 to the position shown to energize coil 31 to reverse contacts 3 to reverse the current in the field 4 and cause the door to close; as it begins to move it closes contacts 22. When the door is fully closed contacts 32 open and de-energize coil 31 to stop the motor. If the closure of the door is not effected within the normal time period, a time delay relay, Fig. 3 (not shown), represented by the contact 8, sends a current pulse through the coil 61 in opposition to the current flowing therein, causing reversal of contact 6 with consequent return of the door to the open position.

Abstract: The scrap to be cut is poured through a top opening (4) into the shears. A cylinder segment (10) can be pivoted about an axis (13) by hydraulic piston/cylinder drives (10a, 10b) and at the same time forms a carrier for movable blades (26, 27). The scrap is reduced in size at cutting edges (24, 25) of the movable blades (26, 27) and at cutting edges (22, 23) of fixed shearing blades (20, 21) and is conveyed to the outside via chutes (28, 29) in the course of the pivoting movement of the cylinder segment (10). By means of troughs (17, 18) formed on the cylinder segment (10) and defined by webs (14, 15, 16), the poured-in scrap between the cutting edges lying apart in each case is prevented from being cut around and from falling out. <IMAGE>
