Abstract: 837,692. Measuring elastic recovery of fluid or semi-fluid materials. LANDAU, L. July 9, 1956 [July 7, 1955], No. 19748/55. Class 106 (2). Apparatus for comparing or measuring the elastic recovery of a semi-fluid or fluid material, comprises a vessel 10, a member 12 supported with substantially point contact in a depression 11 in the bottom of the vessel and rotatable relatively thereto, means to prevent rotation of either the vessel or the member 12 at will, and indicating means 35, 37 serving to indicate angular movement between the vessel 10 and the member 12. A pointed rod 12 rests in a pin bearing 11 in an open cylinder 10, the upper end of the rod 12 being flattened to engage a slot 14 in a bell-crank lever 15 pivoted on a spindle 16. The cylinder 10 is secured by a pin 21 to a rotatable table 20 fixed to a spindle on which is also fixed a gear-wheel 25 in engagement with a gear train 26, 31, 32. A stud 34 is mounted on the gear-wheel 32 to engage the end 17 of the bell-crank lever 15. In use, the vessel 10 is almost completely filled with the substance to be tested and then rotated clockwise six times, by means of a handle 30. After six revolutions the stud 34 engages the bell-crank lever 17, thus releasing the end of the rod 12 and allowing the pointer to swing and so give a measure of the elastic recovery of the material, the container being held stationary. Two identical instruments may be used, thus giving a comparison between a control substance and the material being tested. Such tests may be made at any temperature or at a gradually falling temperature, or thermostatic and heating means may be provided to maintain a constant temperature. In the Provisional Specification, a modification is described in which the rod remains stationary and the vessel revolves. Specification 578,496 is referred to.

Abstract: 189,175. Vickers, Ltd., and Wearham, J. July 22, 1921. Players for keyboard instruments; blowing and exhausting air; expression-controlling; winding-mechanism. -The suction or pressure pump supplying the action wind-chest is manually actuated by a plate on which the operator's palm rests, preferably inserted under a strap or the like. In Fig. 1, the hand-plate C<1> is mounted on a crank C carrying a cam C<x> operating on a roller b<3> mounted on a spring-controlled arm B<3> pivoted at b<3> . With the arm B<3> contacts a roller b<2> on a movable element of the feeding bellows B<2>, which is mounted on the regulating reservoir B<1> communicating with the wind-chest B. As the tension in the reservoir B<1> increases, the roller b<2> is gradually and automatically withdrawn along the arm B<3>, thus giving decreasing amplitude of stroke to the feed-bellows and preventing over-pumping. Loudness is controlled by turning the disc C' in its own plane, a cam C<3> operating on a sliding member C<7> of half-tube section to actuate a cord C<9x> connected to any suitable device. Two cranks and pumping-devices are preferably employed, one at each end of the apparatus. The take-up roll A is driven from one of the cranks C through friction-wheels a, a<1x>, Fig. 3, and a band a<1>. The crank shaft through a chain a<4x> also drives a sprocket wheel a<5>, which by friction-wheels a<6>, a<6x> drives a speed-indicator a<7>. The wheels a<1>x a<6>x are carried by a frame a<2>, which for re-winding, is rocked by a handle a<x>, disengaging the drives of the roll A and speed-indicator a<7> and throwing the wheel a<6x> into contact with a wheel a<8> on the spindle of the roll A<2>. A brake a<9> is also removed from braking the roll A<2>, and a brake a<9x> moved to brake the roll A. In the modification shown in Fig. 5, the hand-plate D, pivoted at its top edge, forms the movable plate of the bellows, which is mounted on a wind-chest of triangular cross-section. Handles, as D<4>, may be provided for varying the tempo and loudness, the music-roll being driven by a pneumatic motor. Specification 186,680 is referred to.

[Also in Division G2] In a system for examining an object by means of a neutron beam, the neutrons after passing through the object, are incident upon a target surface which emits charged particles when neutron irradiated. A visible image of the neutron pattern is formed by the electrostatic charge distribution on a second surface on which the charged particles are collected. The neutron source is a nuclear reactor from which an emergent beam of thermal energy neutrons passes to a collimator which directs the beam to the test object. The detector is formed with lithium as the first surface to provide the charged particles which are collected on a selenium record surface, both being mounted on aluminium base-plates. The reaction employed is The charge pattern in the selenium corresponds with the intensity distribution of the neutrons passing through the test object. The pattern is indicated by the application of an electrically charged powdered pigment to the selenium.

Title: Apparatus for scoring a test sheet
IPC: G09B7/00
Filed: 1973-04-30
Abstract: 1426781 Scoring test sheets SCAN-TRON CORP 30 April 1973 [4 May 1972] 20440/73 Heading G4M Apparatus for scoring a test sheet includes control means for discriminating between a start of test control mark 35 (Fig. 3), a page termination control mark 39 and answer control marks 37, which are all of different size, data channel sensors 29a-29e for sensing indicia concurrently with the detection of the answer control marks and answer checking circuitry responsive to the detection of an answer control mark for comparting a sensed answer with a stored answer and for advancing a counter in response to the comparison. As described a master sheet having an identifying mark is used to enter the correct answers into a memory 38 (Fig. 6) when a program switch 54 is operated. The entry may be verified by again reading the master sheet without closing the program switch when a display 23 should show a score equal to the number of questions. As the master sheet moves past a reading station, in response to answer control marks discriminator circuitry 40 provides signals on line 72 which are fed via logic 66 to provide shift control for register 77 receiving data from the sensors and to increment the address control for master storage 68 fed from the register 77. A test sheet is scored in the vertical or horizontal mode in accordance with whether or not it has a marker horizontally aligned with the start of test control mark which results in a control signal on line 65. As the test sheet moves past the reading station, each answer control mark results in a test answer being read from the master storage to an exclusive OR comparator 81 where it is compared with the sensed data to either trigger an error marker 45 or, if the question is valid, increment decimal counters 88, 89, the former controlling printing of the score when an end of page mark is detected and the latter controlling display 23 to display the total score. The memory 38 may be designed to store the correct answer for two separate tests or for a single test having two sheets, and may comprise two sections each having 250 binary storage locations to store 100 questions each having 5 possible answers. The average score of a number of tests may be computed when an average switch 98 is operated.
