Title: Improvements in cartons
Inventor: HART JACK DENNIS
IPC: B65D5/38
Filed: 1958-07-11
Abstract: 916,011. Drawer and shell boxes. DAVIES & CO. Ltd., ALLEN. July 13, 1959 [July 11, 1958; Sept. 23, 1958], Nos. 22404/58 and 30416/58. Class 18. A drawer and shell box has means for limiting the amount by which the drawer can be extended from the shell so that the box can be used as a dispenser. In one form, Fig. 3, the shell is folded to tubular form from a rectangular blank and the drawer has a slit 16 which engages a tongue 7 in the shell thereby limiting the amount that the drawer can be opened. In a modification used for dispensing cigarettes or pencils, one end of the open part of the drawer is torn away so that the articles can be dispensed from the narrow sides of the box. Several boxes may be arranged side-by-side or compartments may be provided in a single shell. A strut may be provided on the back of the shell to support the box in the dispensing position; alternatively the box may be suspended by means of a hole 6. In the form shown in Fig. 5, two rows of articles are dispensed through openings 40, the drawer having a turned over flap 36 engaged by a tongue 7 on the shell. A vertical partition having a tongue 39 separates the two rows of articles. Each top flap 28 has one article secured thereto for display purposes. Windows 41 give a visual indication of the number of articles in the dispenser.

Title: Holding circuit
IPC: G11B5/58
Filed: 1965-05-28
Abstract: 1,082,891. Electric selective signalling. SPERRY RAND CORPORATION. May 28, 1965 [June 10, 1964], No. 22736/65. Heading G4H. A servo mechanism 18 (Fig. 1) driving a shaft element 10 carrying magnetic heads 12 is driven by an error voltage from a summing circuit 25, the output from which represents the difference between the positions of the magnetic heads and the location of the information tracks being sought by the heads. The error voltage is also applied to a summing circuit 26 together with a reference voltage 34, a detector 30 setting a Schmidt trigger to one of its two stable states when the error voltage approaches zero so that after a delay of five pulses from the Schmidt trigger a counter 38 stops the servo mechanism 18 and operates a brake 52. To prevent the magnetic heads 12 being moved off course by spurious signals the counter 38 emits high negative pulses to a pulse amplitude control 36 so that a high level spurious signal is necessary to prevent the Schmidt trigger resetting. The output from the Schmidt trigger is also applied to a delay member 39 which resets the counter 38 three pulses after the Schmidt trigger has been reset. This ensures that any spurious signals must continue for a predetermined time before they effect the positioning of the magnetic heads.

Title: Stabilising apparatus for ships
IPC: B63B39/06
Filed: 1973-01-03
Abstract: 1358585 Fluid-pressure servomotor systems T N LANG 3 Jan 1973 22803/71 Heading G3P An inertial member 16, Fig.2, mounted to oscillate in response to rolling of a ship operates a first valve 37, Fig.1B, controlling a first actuator 46, Fig.1A, for stabilizing fins 12, 13 and a second valve 30 for further actuators 44A, 44C, Fig.8, which limit the stroke of the first actuator in accordance with the rate of roll. A further actuator 109 may be similarly controlled by means responsive to pitching. Each actuator 46, 109 is connected as shown through telemotors and toothed gearing to the stabilizer fins and is operated by a motive fluid supply controlled by a valve 106 which is in turn controlled by a piston 101. The latter is controlled by the valve 37 and is restrained from moving the valve 106 until a groove 30A in the valve 30 is aligned with ports 34A, 34B to release compressed air from a space 107. The displacement of the valve 30 is made dependant on the speed of the member 16 by connecting it to the latter through fly weights 31 and a chain drive 24. A second tapered groove on the valve 30 supplies motive fluid to the actuators 44A, 44C which move valves 52, 54 to positions determining the limits of travel of the piston 47 while a bank brake 39 operated through a collar 42 and a spring 43 on the valve prevents overtravel of the member 16 at the end of the roll. Valves 67 and 121 permit manual operation of the actuators 44A, 44C and the valve 106 after valves 68 and 123 have been closed. A further manual valve 125 may be used to operate a piston valve 98 associated with the roll sensor and a similar piston valve associated with the pitch sensor so that the stabilizing fins are tilted in opposite directions to oppose the ship's tendency to swing outwards during a turn. In this method of operation, valves 112 ... 115 are used to reverse the effect of the output from one of the telemotor cylinders 111A. The stabilizing fins are situated near the stern of the ship and may be retracted into the hull by screw and nut mechanism driven through chain and toothed gearing from a reversible motor. The master cylinders 44F, 44J of the telemotor may be arranged coaxially with and at opposite sides of the actuator 47. The inertial member, which consists of an air filled annulus with an attached weight 16A mounted in a liquid filled container 20, may be replaced by a gyroscope.
