Title: Underreamer
IPC: E21B10/32
Filed: 1928-12-07
Abstract: 302,900. Grant, J., (Assignee of Edwards, A. B.). Dec. 22, 1927, [Convention date]. Borehole apparatus.-An under-reamer for use in well-drilling operations comprises a hollow cage 10 secured above the drill, and provided with radial slots 15 through which cutters 24 project, outward movement of the cutters being limited by shoulders 25 and the inner edges of the cutters being provided with recesses 26. A hollow sleeve 27 is pressed upwardly by a spring 28 to maintain the cutters normally at the upper ends of the slots 15. A mandrel 16 is held against longitudinal movement in the cage by a threaded collar 21, but is rotatable therein, the rotation being limited by lugs 19 on the mandrel working in arcuate slots 20 in the cage. Upper and lower sets of eccentric parts 22 on the mandrel act during rotation of the latter to force the cutters outwardly through the slots 15; on reverse rotation, the cutters are moved inwardly by contact with the formation being drilled. Alternatively, inward movement of the cutters may be effected by lifting the tool, the well casing then engaging rounded upper corners of the cutters to depress the latter against the resistance of the spring 28, the cutters then moving inward below the eccentric parts 22 of the mandrel, as shown in Fig. 2. The mandrel is hollow to allow passage of flushing medium, escape of the latter being prevented by packing 29 at the lower end of the mandrel.

Title: Adjustable chocks or wedges for securing loads on wagons
IPC: B61D45/00
Filed: 1920-12-24
Abstract: 174,278. Gorrie, J. A. Dec. 24, 1920. Load in bulk, securing on wagons.-Loads are maintained on vehicles during transit by pairs of oppositely-acting adjustable brackets which can be reversed so that their inclined faces G or vertical faces F engage with the load. The inclined faces are formed with guiding- lugs K, sliding between upper and lower flanges C, E on the boxcasing A which is fixed or pivoted on the vehicle. The vertical faces are connected detachably to a nut J having projections N sliding between the lower flange E and the base of the box. With this arrangement, on releasing the vertical faces from the nuts, the brackets can be withdrawn to release the load rapidly without first re-positioning the nuts. The two nuts are operated independently by suitable means, for example, by oppositely-arranged screw shafts R, S rotated by crank-handles. Locking-plates V may slide over the polygonal ends of the screw shafts to lock the brackets in the acting position. The vertical faces F may be extended by sliding plates F'.

Title: Method of packaging material in cartons
IPC: B65B57/04
Filed: 1960-10-21
Abstract: 962,330. Packaging. W. B. LEAVENS. Oct. 21, 1960, No. 36267/60. Headings B8C and B8P. A method of packaging different materials in cartons includes providing a glue lap and a closure flap of a carton blank with indicia representative of the material to be packed in the carton, checking the indicia on the lap, gluing the lap to the body of the blank thus concealing the indicia, checking the indicia on the flap and packing the carton with material in accordance with the said flap indicia. The indicia are in the form of at least one row if a predetermined number of stripes 16 of one or more colours which are checked photoelectronically (see Fig. 1) in known manner to ensure that the number of spaced lines on the lap agrees with the standard code of the material to be packaged. As the cartons pass on a conveyer 10 under the scanning means the number of marks in the different colours are registered on a counter 14 which resets itself after each carton. Where two or more rows of indicia occur on the flap a lap separate scanning means monitor each row. If the coding on the carton does not agree with the standard code resetting does not occur and means are actuated to reject the carton from the apparatus or an alarm or signal is actuated.

Title: Improvements relating to electronic control circuits
Inventor: DION WARREN EMILE
IPC: G05D23/24
Filed: 1954-12-16
Abstract: 771,384. Electric measuring systems. BRISTOL CO. Dec. 16, 1954, No. 36476/54. Class 40 (1). [Also in Group XXXV] Automatically balanced bridge apparatus for e.g. measuring temperature incorporates a servo-amplifier with positive feedback whereby changes in the error voltage are augmented to accelerate the balancing of the bridge by a servomotor. As shown (Fig. 1), a bridge B comprises a temperature-sensitive resistor 15 and a variable resistor 14 adjusted by servomotor M<SP>1</SP> to restore balance. Any unbalance voltage is amplified by push-pull valves 38, 39 and fed directly to valves 52, 53 whose anodes are supplied with A.C. from the mains 22 via the windings of relays R<SP>1</SP>, R<SP>2</SP> so that one of the valves 52, 53 conducts, depending on the direction of the unbalance in bridge B, to cause relay R<SP>1</SP> or R<SP>2</SP> to operate, thereby energizing field winding 26 or 27 of motor M<SP>1</SP> which rotates in the appropriate direction to drive the slider 16 of resistor 14 and restore balance. The circuit is such that current flowing in valve 52 or 53 reduces the voltage across capacitor 60, which discharges through resistor 43, and increases bias on valves 38, 39, and is followed by a bias reduction on valves 52, 53, whereby their anode currents increase to enhance the energization of relay R<SP>1</SP> or R<SP>2</SP>. A reduction in error voltage is similarly accentuated to cause the relays to drop more sharply. If the speed of the motor M<SP>1</SP> is high the bias voltage developed across resistor 43 could be maintained after the error signal from the bridge has been considerably reduced, whereupon both valves 52, 53 conduct simultaneously, both relays R<SP>1</SP>, R<SP>2</SP> are energized to break the motor field circuit, thereby anticipating the balance condition. Alternatively, the relays may switch the direction of current in the armature 25 of the motor, short-circuiting it when both relays are operated simultaneously to provide a braking action which minimizes hunting. To improve the performance resistor 43 may have a non-linear characteristic.

Title: Improvements in or relating to hydraulic relays
IPC: F15B9/17
Filed: 1954-12-16
Abstract: 805,005. Correspondence control systems. SOC. D'INVENTIONS AERONAUTIQUES ET MECANIQUES S.I.A.M. Dec. 16, 1954 [Dec. 18, 1953], No. 36518/54. Class 40 (1). [Also in Group XXIX] In a control system, the error of position of a controlled member is applied to a relay in the form of an electrical potential which varies directly as the error and the relay comprises two valves T, Fig. 1, the casings of which are each provided with motive-fluid inlet and exhaust ports, a control chamber e, and a chamber v leading to one side of a jack V constituting the controlled member; the chambers e communicate with an electro-hydraulic device actuated by the electrical control potential; and the valves T are each formed with an annular chamber u in communication with the chamber v. Two potentiometers p1, p2 are connected so as to constitute a Wheatstone bridge with the sliders connected together through resistors R1, R2. The slider of potentiometer p1 reflects the position of the controlling member while that of potentiometer p2 is connected to the piston rod of the power device V and indicates the position of the controlled member. Any error in correspondence between the positions of the two sliders provides an e.m.f. at the junction of resistors R1, R2 which is passed through an amplifier a to give equal opposed outputs for actuating solenoid valves 7, Fig. 4, differentially. Pressure liquid is supplied from a conduit P, through restrictions 4, and into chambers 2 from which it can escape to exhaust past the valves 7. The position taken up by a valve 7 determines the pressure in the corresponding chamber 2, and this pressure is applied through a conduit 3 to act on the lower end of a valve T. Normally, the pressure in the jack chamber and above the valve T balances the pressure underneath the valve with the loading spring R in an unstressed condition. An increase in pressure underneath valve T raises the latter until pressure liquid from conduit P can flow through passage n and so into the appropriate end of the jack. A lowering of the pressure underneath valve T causes the latter to be pushed down until a series of ports B leading to exhaust are uncovered to allow the liquid in that end of the jack to flow to exhaust until its pressure is lowered sufficiently to balance the pressure underneath valve T. The passages controlled by valves 7, Fig. 4, pass through the coils 9 of the electromagnets and the downstream fluid is allowed to act on the upper side of a piston 8 contacting the valve 7 so as to load the latter to the closed position. After passing through a restricted passage 13, the downstream fluid, then at a lowered pressure, is allowed to act upwardly on the piston 8.

Abstract: 1,168,415. Image converter tubes. MULLARD Ltd. 31 July, 1968, No. 36567/68. Heading H1D. [Also in Division C1] A channel intensifier device has a matrix of glass of the following composition in mol. per cent: SiO 2 -70 to 80; Al 2 O 3 -O to 4; PbO- 7.5 to 18; Na 2 O and/or K 2 O-O to 13; Bi 2 O 3 - 0.5 to 4; and the channel surfaces have a conductive reduced-oxide layer with a resistivity in the range 10<SP>10</SP> to 10<SP>14</SP> ohms/square. The glass composition may also include up to about 1 % of added material composed of specific agents and/or unwanted impurities. In one example suitable for a small high-definition channel plate having channels about 40Á in diameter or less, the glass comprises SiO 2 , 73.3, Al 2 O 3 1À1, PbO 10.8, Na 2 O 5.9, K 2 O 6À9, Bi 2 O 3 2.0, and the channels are treated by a hydrogen reduction process to give a resistivity p such that log p is about 12.15. In another example for an X-ray image converter with a channel diameter of 100 Á, the SiO 2 is reduced to 72À3and the Bi 2 O 3  increased to 3, the remaining elements being the same. The reduction process gives log p of about 11.20.

Filed: 1956-11-30
Abstract: 813,070. Electrostatic separation. QUAKER OATS CO. Nov. 30, 1956 [Dec. 2, 1955], No. 36670/56. Class 117 [Also in Groups XXXV, XXXVI and XL(a)] Electrostatic separation apparatus includes an electrode with means for limiting the energy of a spark which may occur when the air gap or the insulation value of the air gap through which the material being treated passes is substantially reduced. As shown, an electrode 10 comprises a tube 20 containing a bus-bar 21 and provided with a series of needle-like emission elements 25. A liquid having substantial electrical resistance is contained within the tube and preferably consists of one or more of the solutes diphenyl, diphenyl amine, thiodiphenylamine, pyridine, benzophenone, or diphenylmethane, in a solvent comprising a mixture of chlorinated phenyls and polyphenyls in polyhalogen substitution products of benzine. Connection to the positive pole of a high voltage source 16 is by means of a plug 35 engaging a member 31 having a rod 32 contacting the busbar 21. Fig. 4 shows the electrode 10 used with a grounded drum 12 on to which material to be separated is supplied from a hopper 15; a divider 14 assists in the separation of the material. In the event of the air gap F being reduced by tramp metal or its insulation being lessened by high moisture content material passing through it, the energy level of any spark which may be produced is restricted by the degree of electric isolation provided by the liquid between one emission element and another. The proportions of the solutes and solvent for the liquid are chosen to provide the required current flow from the bus-bar to the elements 25. In a modification, Fig. 5 (not shown), the bus-bar is a cylindrical member with which the plug connector directly engages.

Title: Improved method of and apparatus for measuring a diameter of a ring seal
IPC: G01B13/12
Filed: 1959-11-02
Abstract: 873,930. Pneumatic gauging apparatus. GENERAL MOTORS CORPORATION. Nov. 2, 1959 [Nov. 12, 1958], No. 37095/59. Class 106 (2). [Also in Group XXVI] A method of measuring a diameter of a ring 10 comprises effecting relative movement between the ring 10 and a tapered member 18 to reduce the annular gap between the ring and the member whilst passing fluid through the gap, and ascertaining the relative positions of the member 18 and the ring 10 when the rate of mass of fluid flow reaches a predetermined value. The ring 10 which may be a lip seal is mounted on a piston 20 movable along a cylinder 16. A tapered mandrel 18 passes through a pair of holes 38, 40 in the piston 20 and is fixed to the base 14 on which is mounted the cylinder 16. Air under pressure is supplied to the cylinder 16 through a conduit 84. In operation, air at constant pressure is admitted to the cylinder 16 and the piston 20 is moved downward by a handle 58 until the volume air flow has almost reached the predetermined value. Final adjustments are then effected by swinging a half-nut 76 into engagement with a screw-thread 62 and turning this latter by a thumb-screw 64. When the volume rate of flow of the air has decreased to the predetermined value, the position of the piston 20, indicated on a scale 80, is used to determine the size of the ring 10. If the ring 10 is mounted on the lower portion 36 of the mandrel, and the air pressure increased until the lip of the ring 10 pulls away from the mandrel, the pressure at which this happens is a measure of the elasticity and uniformity of the ring 10.
