Title: Apparatus for delivering newspapers or the like
IPC: G07F11/04
Filed: 1929-03-02
Abstract: 334,497. Parfett, F. March 2, 1929. Sheet-separators; pile tables. - In apparatus for delivering newspapers, books, packets of stationery, handkerchiefs, &c., a reciprocating plate enters between the two uppermost articles of a stack of articles to be delivered, and on its return motion removes the article above it., means being provided to lift the stack between each delivery through a distance equal to the thickness of one article. In the apparatus shown, a stack 5 of articles is supported within a casing 1 on a platform 9, carried by a post 10 sliding in a fixed sleeve 11 under the pressure of a spring 13, which brings the top article into contact with an abutment 14. On the actuation of a driving shaft 3 by means of a handle 7, a plate 15, connected to the shaft 3 by arms 18 and links 19, is moved along guides 17 to enter the stack beneath the top article, thus separating it from the lower members of the stack. On the return motion of the plate this article is delivered through a slot 16. The abutment 14, which consists of a block of rubber, is carried by an arm 21 and crank 22 from a shaft 23, which is turned from the shaft 3 by means of a connecting rod 26. The position of the abutment 14 is determined by a projection 28 on the arm 21, which projection during the forward movement travels along the lower edge of a cam 29 pivoted to a bracket 30 but during the return movement travels along the lower edge of the bracket. Motion of the cam 29 is restrained by a spring 33 and that of the arm 21 by a spring 32. The motion of the abutment 14 is such that it first causes a puckering of the top article, if this is flexible, so as to facilitate entry of the plate 15 below it, and that it then rises so as to free the top article for discharge and finally returns to its normal position, where it determines the position of the top member of the stack for the next operation. Upward motion of the post 10 during the motion of the plate 15 is prevented by a device, shown in Fig. 7, which consists of a friction shoe 34 bearing against the post under pressure of a spring 37, when a cam 41 is turned by connections from the shaft 3. The apparatus may be operated electrically instead of manually and provided with coin-release mechanism. It is stated that the stack instead of being supported as described may slide in vertical guides under the pull of a counterweight. The Provisional Specification describes a method of operating from the shaft 3 a brake lever, which controls the upward movement of the stack in the last-mentioned arrangement, and also modified methods of supporting the abutment, which positions the uppermost member of the stack, and of operating it from the shaft 3, and modified connections between the shaft 3 and the tray, which connections operate also a member which causes puckering of the uppermost article.

Abstract: 943,284. Fluid-pressure servomotor control systems. SPERRY GYROSCOPE CO. Ltd. Feb. 21, 1962 [Feb. 24, 1961], No. 6853/61. Heading G3P. A fluid-pressure servomotor system controlling a displacement of e.g. a control surface of a manoeuvreable craft, has a first control mode in which the system is under the control of a signal derived e. g. from automatic control means 43 and a second control mode in which the surface is displaced e. g. under manual control. An auto-pilot 43 acts through an amplifier 42 to position the piston valve 20a to allow pressure from pump 35 to pass to changeover valve 21. A solenoid 37 or hydraulic pressure may position the valve 21 manually or automatically on failure of hydraulic pressure, so that the pump pressure is returned to reservoir 34 and the lever 16 may be operated manually in virtue of the lost motion between its arms 12, 13 and operating pistons 3, 4. The lost motion may be formed by slack cables or by the arms entering the piston recesses 14,15. During hydraulic operation pressure fluid is delivered to the two pistons in accordance with the signals from the automatic pilot, the pistons move against the springs 9, 10 to take up the lost motion and move lever 16, pick-offs 38, 39 producing an electrical feedback via 43a to the control valve 20 and amplifier 42. To prevent shock due to one piston engaging one lever arm before the other, the pistons may engage spring arms 40, 41 on the pick-off 39 which then feeds back via 39a to act on the control valve 20 and ensure that the pistons contact the arms simultaneously.

[Also in Divisions G2-G3] An integrating light meter for use in flash photography has an RC circuit to control the integration time, operates synchronously with the flash trigger and has an output which is proportional to the logarithm of the time-integrated photoelectric current. A photo-voltaic cell 3 is located in a differential amplifier comprising field effect transistors 7, 8 and feedback is provided by means of transistors 12, 13 and resistance 18 so that the points a and b are maintained at a constant potential when the photo-current changes, the result being that the latter is proportional to the incident illimination over a wide range. The photo-current, amplified by transistor 4, is fed to an integrating condenser 21 through diodes 19, 20 and it is shown that the voltage attained by condenser 21 is directly proportional to an exponent of the total light quantity incident on the cell 3. The voltage across condenser 21 unbalances a second differential amplifier comprising transistors 23, 24 and a reading is obtained on a meter A which is simply related to the exposure and which may be easily corrected for different film sensitivities, for example by movement of the meter scale Fig. 11 (not shown). Synchronous operation with a flash-gun is achieved by means of a coupling between power switch 2, condenser shorting switch 22 and flashgun switch 36, Fig.9 (not shown), so that the switches are operated in the correct sequence. Closure of switch 2 initiates charging of a condenser 32 through variable resistance 33 and when a sufficient voltage is obtained, transistor 4 is blocked to end the integration period.
