Title: Detecting distortion of terrestial magnetic field
Inventor: FRANKLIN PHILIP JAMES
IPC: G01V3/08
Filed: 1966-03-10
Abstract: 1,179,841. Magnetic detectors in road vehicles. SPERRY RAND Ltd. 28 March, 1967 [10 March, 1966], No. 10554/66. Heading G4Q. [Also in Division G1] Two arms of a conventional Y-cored flux valve are connected in series to provide an output signal dependent on change in direction of the earth's field due to the presence of e.g. a vehicle. A D.C. energized trimming coil may be used to shift the local ambient field direction for zeroizing. A differentiating circuit may be included in the output, Fig. 4 (not shown), to send on signals only from moving vehicles, and not steady signals from those parked. Since each vehicle may produce three or four pulses due to magnetized parts, a correction of the count may be necessary based on statistical analysis of the content of the traffic. Details of the oscillator, amplifier and trigger circuit are given in Fig. 3 (not shown).

Abstract: 311,900. Paige, W. R. April 10, 1928. Saws.-A hack saw comprises two transverse .frame members adapted to hold two blades and adjustably and pivotally mounted on a longitudinal supporting member, the transverse members either passing through or embracing the longitudinal member. The blade carrying members each have a bifurcated portion s to embrace the supporting member a, the forward end of the latter being reduced at y and provided with shoulders x engaging notches in the forward blade carrying member c; the rear member c is secured by a screw v and nut t with flanges w forming guides to prevent lateral displacement. Blades d are secured to the arms c, one on either side of the member a. and tensioned by a screw and nut c. The handle m is adjustable on the member a. The Provisional Specification describes and illustrates other constructions. The supporting member a, Fig. 1 (Prov.) is slotted at b to take the blade carrying arms c, the forward one of which has notches g engaging the projection f. Tension is applied to the blades d by the screw c, and the blades may be held in two positions at right angles on pins j, k. The handle m has a split metal socket n and is secured in different angular positions on the member a by screws o ; notches p engaging the handle prevent movement of the arms c during use. A cotter or pin placed in a hole r in the member a and in one of a number of holes q adapted to register therewith also prevents displacement. In the modification, Fig. 5 (Prov.), the handle m is adjustably secured to the supporting member a by the screw t holding the blade arm c, and has a sheath portion v to give the member a extra support. In a further modification, Fig. 6 (Prov.) the handle m is fixed to a looped extension w formed on the member a.

Abstract: 1,184,822. Dynamometers. ENGLISH ELECTRIC CO. Ltd. March 1, 1968 [March 8, 1967], No. 10828/67. Heading G1W. A torque-sensitive hydraulic machine coupled to a driving or driven shaft 6 is mounted in a support 10, 12, 14 with freedom to swing about the axis of the shaft 6 against the restraint imposed by the stiffness of a resilient pipe 18, which serves as the inlet or outlet pipe, and means 30 sensing the angular displacement of the machine in response to torque. As shown, a dynamometer includes a pump whose casing 4 can swing in ball bearings supporting the shaft 6 and a trunnion 8. One end of the casing 4 carries a connector block 16 with lateral clearance in a recess 24 of a yoke 22 secured to the stationary bracket 10. Inlet and outlet blocks are connected between the swinging block 16 and stationary pipes 32, 34 through floating bridge pieces 36, 38, and supplementary pipes 40, 42. The stationary yoke 22 has a flange 26 to react on the plunger 28 of an angular displacement detector 30 mounted on the block 16. The torque absorption of the pump can be regulated by adjusting a restrictor between the outlet pipe of the pump and a source to which the fluid is returned. The detector 30 may be a dial gauge or an electrical transducer and it may be detachable. Reference is made to other methods of mounting the machine with freedom for limited swing and to various arrangements of resilient pipes which may be steel pipes. The hydraulic machine 2 may be a motor required to transmit a controlled torque e.g. for coiling sheet material.

Title: Improvements relating to copy-milling apparatus, particularly for pattern milling and like operations
IPC: B23Q35/10
Filed: 1944-06-09
Abstract: 581,497. Copying by milling. LEVY, B. June 9, 1944, No. 11100. [Class 83 (iii)] A machine or an attachment to a verticalspindle milling machine to enable copying to be performed from a pattern comprises a standard 3 adjustable along rails 1 attached at either side to the milling machine 2 or the floor and capable of being secured in the adjusted position. A table 17 capable of being traversed in a direction perpendicular to the rails 1 is mounted on the machine table 7 and carries a work table 18 movable on guides thereon parallel to the rails, weights 19 being suspended by cords 21 from the tables 17, 18 so as to maintain a tracer 22 on table 18 in contact with a pattern 26 carried by a table 6 on the standard 3. As the table 17 is traversed, the table 18 is moved thereon to cause the stationary milling cutter 25 to shape the work 23 to the same form, but of opposite hand, to the pattern 26, or an adjustable pantograph linkage may be interposed between the tracer and the table 18 to vary the scale of reproduction. After each traverse, the arm 13 carrying the cutter is raised or lowered and an inextensible flexible connection 11 connecting the arm to the pattern table 6 causes the latter to be raised or lowered correspondingly so that the shape of the pattern in the vertical plane is also reproduced on the work. A pantograph may also be used to vary the scale of vertical reproduction. The connection 11 passes over pulleys 12 carried by the standard 3 and by a bracket 14 attached to the machine, and the weight of the cutter arm and pattern table are balanced by weights 10. Instead of being formed as an attachment the apparatus may be built into a milling machine and the weights 19 may be replaced by springs. To surmount abrupt portions of the pattern, the table 18 may be actuated by a hand wheel 27 to withdraw the tracer from the pattern, and vertical movement may be given to the work instead of the cutter. The connection 11 may be arranged to cause the cutter and pattern to move in the same or opposite directions for reversing the hand of reproduction, and by arranging the work and pattern on the opposite side of the cutter from that shown, intaglio work may be produced from a relief pattern and vice versa. A laminar edge pattern may be used for producing a recess &c. in the work having a similar cross-section, the connection 11 then being removed so that the cutter may be given a step-by-step vertical feed whilst the pattern remains stationary.

Abstract: 660,859. Fluid-actuated valves. TRIUMPH DISHWASHERS, Ltd. April 28, 1949 [May 1, 1948] 11350/49. Class 135. A valve which functions as a stop valve and a pressure regulator comprises a housing 1 with an inlet 2 and an outlet 3, a main valve closure member 12 controlled by a solenoid-operated pilot valve 20 and a spring- loaded diaphragm 26 having a sliding connection with an extension 14 of the valve member. Inlet pressure acting through a port 19 holds the member 12 seated, but is exhausted through passages 17, 18 when the solenoid is energized to open the pilot valve 20. Inlet pressure then unseats the member 12 and outlet pressure,acting through a port 11, lowers the diaphragm until a ring 40 on the extension engages the upper end of a bore 32 formed in members 29, 30 carried by the diaphragm. The member 12 is then controlled by the diaphragm to maintain a constant inlet pressure. On de-energizing the solenoid, inlet pressure closes the member 12. The solenoid may be controlled by a suitable time delay relay or a cam mechanism to effect operation of the valve at desired time intervals.
