Title: Determination of the degree of compaction of a surface by means of a compactor having wheels
IPC: G06J1/00
Filed: 1973-05-23
Abstract: 1418382 Measuring compaction electrically SOC ANON DITE RICHIER 23 May 1973 [25 May 1972] 24651/73 Heading G1N A roller is driven back and forth over a selected surface area to compact the earth to a desired degree, the compaction being satisfactory when the engine torque increase for successive sweeps is less than a predetermined quantity, for three consecutive sweeps, torque measurements being made for travel in both directions. The roller speed is measured at 4, Fig. 2 by the frequency f of a pulse train, which is counted at 9, 10, 11 to determine when the roller has covered the test surface, the logic circuitry eliminating stopping and reversing in zones on either side of the measuring area. The frequency f is also converted at 6 to a corresponding D.C. voltage and multiplied at 7 by the torque signal measured at 1, the product being converted at 8 to a pulse frequency F. This is divided at 28 by the length l of the test surface, pre-set at 15, and at 29 by the number of passes p required to cover the test area, pre-set at  19, to give a pulse train which is integrated at 33 to give a count shown to be proportional to the average torque for the complete sweep of the test area, when the roller speed is maintained constant. This count is fed to a subtractor 34, where it is stored for one sweep, and compared with the next count at 33, to determine the difference at 35 and compare it with a predetermined difference number e. If the difference is less than e twice, for three consecutive sweeps, an indicator 42 is energized to signal that the desired degree of compaction has been attained.

Title: Improvements in or relating to suction cleaners
IPC: A47L5/32
Filed: 1934-08-27
Abstract: 438,622. Vacuum cleaners. HOOVER, Ltd., Perivale, Middlesex.-(Hoover Co. ; North Canton, Ohio, U.S.A.) Aug. 27, 1934, Nos. 24691 and 27810. [Class 8 (i)] In suction cleaners of the type which are adapted to be moved over the floor and have a main nozzle provided with a downwardly opening suction nozzle for cleaning the floor, means are provided whereby the act of placing the cleaner in condition for use with a dusting tool necessitates or causes operation of means for putting the circuit of the motor into condition for operation at a higher speed. Fig. 4 shows a construction, wherein movement of the operating handle G to a position for storage actuates a contact F<1> for increasing the motor speed and also rotates a cranked spindle carrying the floor wheels A<3> to raise the agitator clear of the floor. A converter J shown in Fig. 5, is similar to that described in Specification 422,609 and when moved into a position for dusting, an arm K<1> is rotated by the cam M and actuates a motor switch L, and also a quadrant M<5> rotates a pinion M<6> to move a mask which lifts the belt driving the agitator from its pulley. In a further modification a cover N<5>, Fig. 9, is removed and replaced by the converter P for dusting purposes. The cover N<5> has a lug O<2>, the removal of which actuates the contacts O<1> of the motor switch. The converter P has contacts P<3> which engage contacts P<4> to energize a solenoid Q which disengages a clutch in the drive to the agitator. The first Provisional Specification also describes means whereby the agitator is rendered inoperative by a shield under the suction nozzle. In another form a manually operable member prevents the insertion of a converter until it is removed, which action operates the motor switch. Further, the clutch in the agitator drive is controlled by switches operated by the handle. In another form two fans are provided and one is declutched by insertion of converter which also operates the motor switch.

[Class 27] Mechanism for prepaying basic charges.-In a prepayment electricity meter wherein, for adjusting the basic charge, an oscillatory pawl-lever actuated by a time element and forming part of pawl-gearing connected to the quantity mechanism is adjustable by adjusting a pin coacting therewith, the pawl-lever 8, Fig. 1, carrying a driving pawl 10 is fixed to a shape 25 to which is secured a gear wheel 6 meshing with a toothed quadrant 7. The quadrant is carried by a lever 4 actuated by a pin 3 on a disc 2 driven by the time element, e.g. a synchronous motor. The lever 4 is rocked in one direction by a pin 3 and returned by a spring 5. The pawl 10 drives a ratchet wheel 9 loose on the shaft 25 and rigid with a wheel 11 forming part of the drive to the quantity mechanism, a pawl 13 preventing reverse rotation. A pin 17, carried by an adjustable indicating disc 16 determines the stroke of the lever 8, the pin 3 moving away from the lever 4, when the lever 8 is in contact with the pin 17. In a modification, Fig. 2, the time motor drives a pin wheel 2 having a space 22 with no pins. The pins 20 on this wheel engage a toothed wheel 21 rigidly connected to the pawl-lever 8, the wheel 21 having an enlarged tooth space 23. The wheel 20 rotates the wheel 21 and arm 8 in the non-driving direction against the action of a spring 5 until the space 22 releases the wheel 21 whereupon the wheel 21 is returned by the spring until the arm 8 contacts with the adjustable pin 17.

Abstract: 1452666 Burglar alarms RCA CORPORATION 10 June 1974 [15 June 1973] 25580/74 Heading G4N [Also in Division H1] A radiation detector 10 comprises a radiationsensitive body 12 with opposed surfaces carrying electrode arrays, each electrode in one array overlapping two electrodes in the other to form elemental detector regions 22a-h with the electrode forming a series connection across the body. The sensitive material 12 is preferably a pyroelectric material and the electrodes are of metal film. As shown, the detector may be used with a grating 30 to detect only a moving radiating body e.g. for a burglar alarm. In this application each elemental detector is polarized in the same direction. Adjacent detectors will generate a voltage of the same polarity as one cools and the next one heats up due to passage of the radiating body in front of the grating e.g. from direction 34 to 36. When all the detectors 22a-h heat or cool together, voltages of alternate polarities are generated and cancel to give no signal for changes in ambient temperature. In another arrangement, the elemental detectors are polarized in alternate directions so that changes in ambient conditions or incident radiation generates a signal of the same polarity from each Fig. 3 (not shown). The electrodes may be straight parallel strips or concentric annular or oval shapes.
