Patent GB-535009-A (GB)
Title: Improvements in or relating to apparatus for weighing, tensile testing or for other like purposes
IPC: G01G1/00
Filed: 1940-01-18
Abstract: 535,009. Weighing-apparatus. DONNELLY, V. J. F., and MORGAN, J. E. H. Jan. 18, 1940, No. 1797/39. [Class 143] [Also in Group XIX] For measuring the force exerted in a testing machine or in weighing apparatus &c. a rod member or the like of known physical properties is strained well within its elastic limit and the deformation measured by a dial indicating device calibrated in load units, the construction being such that when the load is released, the actuating means for the indicating pointer is moved away from the indicating device and the pointer restored to zero independently. In the tensile testing machine of Fig. 1, the specimen 43 is attached by grips 44 at the lower end to a straining screw 45 prevented from rotation by a cross-head 58 guided on the machine pillars 3. The upper end of the specimen is attached by grips to a rod 1 of heat-treated spring steel suspended from the bridge piece 2 connecting the pillars 3. The latter extends upwards from a straining block 4 passing a nut driven by a worm gear 51 from a two speed gear and reverse 56 driven in turn from a motor 54. A ballthrust bearing 48 takes the thrust of the screw and spherical bearings are provided top and bottom so that the pull is properly aligned with the axis of the specimen. The rod 1 is chosen so that the maximum pull strains it well within the elastic limit. Secured to the rod 1 at the top is a tube 8 which carries a dial gauge 9. To the lower end of the rod 1 is secured a tube 20 which telescopes over the tube 8. A bracket 25 attached to the tube 8 carries a screw 27 provided with a hardened tip to engage the plunger 23 of the dial gauge. The extension of the rod under load is thus communicated in an amplified form to the pointer of the gauge and measures the load. In a modification two parallel metal rods are used arranged at right angles to the specimen. Arms attached to each rod at the middle extend towards the other rod and the free hooked ends are engaged by the hooked end of a weigh bar to which the end of the specimen is clamped. The rods are then placed under tension and the twist of one of the bars is transmitted by rack and pinion to a dial indicator. In a further form the standard rod is placed under bending stresses.
Patent GB-285870-A (GB)
Title: Improvements in the automatic protection and control of electrical installations
IPC: D01H1/243
Filed: 1928-01-19
Abstract: 285,870. Schild, S. Feb. 24, 1927, [Convention date]. Cut-out arrangements.-Electrical systems, for example, the incoming lines L1, L2, the power transformers A, B, C and the outgoing lines L3, L4 are protected against fault by means of a maximum and minimum relay N which through switching mechanism K isolates all parts of the system on fault, and then reconnects them in sequence, and switches off the defective parts by means of a maximum current relay M. Upon removal of the fault, the defective parts are switched in again automatically. The switches which isolate the various parts of the system A, B, C, and A2, B2, C2, for example, are of the double coil type one coil when energized serving to close the switch and the other to open it. The energization of these coils from the battery D is under hand control by the selector W which determines which of the main switches shall come under the automatic control of the cutting-out and resetting controller K which is driven by the motor G when the voltage relay in one of the incoming lines assumes one of its closed positions due to increase or decrease of voltage. When, for example, the line L1 becomes live the contacts a, b of the relay N close and the motor G commences to rotate the drum. The connections of the drum controller to the main switches are such that the main switches in the system are closed in sequence. During this switching-in action, if a fault occurs in the next succeeding section (for example, between the switches A1 and A2) then the maximum relay M will operate and the main switch just closed will be opened again. In position 11 of the controller, it is stopped as the supply is automatically cut off from the motor G. If the voltage on the conductor L1 fails, for any reason, the motor is restarted and all the switches are switched off at position 13 of the drum. In position 14 the motor is again stopped and only on reappearance of voltage on line L1 is the switch mechanism again set in operation by the voltage relay N.

Filed: 1943-02-05
Abstract: 563,379. Drying air. WESTINGHOUSE BRAKE & SIGNAL CO., Ltd., and PETER, L. H. Feb. 5, 1943, No. 1950. [Class 34 (i)] [Also in Group III] In apparatus for removing moisture from compressed air by passing it through or over silica-gel &c. the material is regenerated for heating by heat evolved by the compression of the air. In the example shown the silica-gel is contained in two de-hydrator elements 2, 3. The compressor head 1 is enclosed by a casing 4 through which air is blown by a fan 5. Air intake 7 to the compressor 1 has a strainer and air outlet 8 leads to reservoir 9. Pipe 10 leads to a reversing cock 11 to allow of (1) communication between pipe 10 and a pipe 15 leading to dehydrator 2 and (2) connection between pipe 6 from casing 4 and pipe 16 leading to the other dehydrator 3. A similar reversing valve 17 can put one or other of the dehydrators in connection with pipe 21 to the utilization point or 24 to the outside air. As shown, dehydrator 2 is in action while 3 is being regenerated. In a modification, air is dehydrated before compression, and in another part of the air compressed and, therefore, heated in compressor 1 is used for regeneration. In a further modification the heating for regeneration is effected by the passage of the compressed air through tubular heat exchange apparatus in the dehydrator before passage to the casing of the other for dehydration.

Title: Improvements in liquid level indicators for reservoirs
IPC: G01F23/50
Filed: 1931-01-20
Abstract: 371,853. Indicating liquid levels. FARFALLINI, I., 28, Via Aquila, Turin, Italy. Jan. 20, 1931, No. 1951. [Class 123 (i).] In a liquid level indicator of the type in which a flexible transmission is actuated by hand at the indicating point to an extent which is determined by the position of a float, the flexible transmission comprises a flexible wire surrounded by a helical coil of relatively large pitch, and then by the usual casing. In Fig. 1, a pointer 1<11> moves over a graduated dial, and its spindle is provided with a pinion 3 gearing with an annular-toothed rack 4 connected to a wire 5 which is attached at its further end to a sliding piston 8. The piston is guided in a tube 9 by a slot moving over a fixed pin 11 and is pressed outward by a spring 10. The wire 5 is tensioned between the springs 10, 12. The other end of the rack is connected to another flexible wire 13, and, in accordance with the invention, a helical coil 14<1> of relatively large pitch is interposed between the wire 13 and the flexible metal casing 14 in order to reduce friction. A similar coil 6<1> is arranged in the casing 6, and is preferably of smaller pitch, while the wire 5 may be of a material such as twisted catgut. The other end of the wire 13 is attached to a rack 15 and the wire is tensioned by a spring 16. The springs 12, 16 are each weaker than the spring 10. The rack 15 engages a pinion on a spindle 19 having a helical groove 19<1>, and passing through a float 22. As the float moves vertically due to variations in liquid level, it is also moved angularly, and thereby determines the amount of rotation which can be given before the stop 22<1> comes into contact with a projecting strip 21. This rotation is effected by pressing the knob 7, and its amount is indicated by the pointer 1<11>. In a modification, hand actuation of the flexible wire is effected bv a knob on the spindle of the indicator pointer, and in another modification, by means of a pawl' device which actuates a rack on an extension of the rack 4.
