Abstract: 514,688. Recording-apparatus. PERMUTIT CO., Ltd., and MILTON, J. G. May 7, 1938, No. 13711. [Classes 106 (ii) and 106 (iv)] [Also in Group II] In apparatus for recording the flow of gases in which the flow is determined by the setting of a control device means are provided for recording the setting against time and for interrupting the record when no gas is flowing. As applied to a chlorination apparatus wherein chlorine'is added to water for sterilization purposes, the apparatus comprises a bell jar 1 inverted over water in a container 2 the chlorine gas being supplied by a pipe (not shown) and drawn by suction through an orifice 3 in a tube 4. A tube 5 within the tube 4 passes out through a fluid tight gland in the bottom of the container and is connected to a pipe which leads to the water to be treated. The rate of flow is adjusted by a control device 6 which moves the tube 5 vertically. An arm 8 movable with the tube' 5 carries a pen 9 that co-operates with a time-driven drum 10. A sylphon bellows 11 is connected to the arm 8 and responds to the pressure of gas in the bell jar through a pipe 12. If the flow of gas is interrupted by removing the suction the pressure in the bell jar rises and lifts the pen from the drum. If the supply of gas fails and the flow is thereby interrupted the pressure drops and a second pen 13, normally inactive, is brought into contact with the drum to produce a second trace.

Title: Digital electronic data processing systems
IPC: G06F9/48
Filed: 1969-03-17
Abstract: 1,267,582. Digital computers; interrupt mask. BURROUGHS CORP. 17 March, 1969 [15 March, 1968], No. 13825/69. Heading G4A. A multi-module data processing system has a mask register within each central processing module which selectively prevents specified stored interrupt signals, received from the other modules, from interrupting the normal operation of the central processing module and means for preventing interrupts allowed by the mask from interrupting the central processing module. Each processing module is identical and operates in a normal mode asynchronously in parallel under an executive scheduling programme (ESP). Up to 70 different interrupt signals can be received and stored by an interrupt condition register 6-10, there being means for preventing the same two signals being received from different modules simultaneously. The ESP controls, for each processor, the 70 bi-stable individual mask registers 6-12 that determine which conditions are allowed to interrupt that processor. If the two correspond for that signal, an interrupt is generated from AND gates 6-14 which causes storing of the basic information for normal mode program resumption, and the processor enters control mode 1. In this control mode 1, certain fewer interrupts are allowed and the mode is shifted from the control mode back to the normal mode under control of the control mode 1 and the normal mode programme continues to run without being automatically interrupted (subject to mask) as it was when it was originally in the normal mode. Also it is stated that the machine can effectively change its mode from the control mode back to the normal mode without actually leaving the ESP programme. A control mode 2 is also provided if control mode 1 is interrupted and if control mode 2 is interrupted the operation stops as shown on Fig. 6. Other features mentioned include simple parity bit checking, 512 simplex I/O lines including magnetic tape and card readers, teletype lines &c. and high speed thin film memories. The calculating parts can perform the four rules of arithmetic and may be used on accounting problems.

Title: Improvements in or connected with Protecting Devices for Multiphase Alternating Current Apparatus.
IPC: H02H3/33
Filed: 1916-10-09
Abstract: 111,125. Beard, J. R., and Electrical Improvements, Ltd. Oct. 9, 1916. Protective arrangements.-In automatic devices for disconnecting faulty multiphase apparatus from the mains, the two ends of each phase winding a<1>, a<2>, a<3> of the apparatus are taken round the cores e', e<2>, e<3> of transformers in such directions that when the phase windings are healthy and the currents at the two ends of each equal, no resultant flux is produced in the cores. In the event of a fault occurring, the opposing ampere-turns are no longer equal, and an electro-motive force is induced in a secondary winding g which in turn opens the circuit breaker b through a relay h and a trip coil i energized from a battery j. In applying the invention to a transformer, the primary and secondary windings on each limb are protected separately, and the occurrence of a fault causes the opening of the circuit-breakers on both the primary and the secondary sides of the transformer. Specifications 15796/04, 4004/11, and 13355/12 are referred to. Reference has been directed by the Comptroller to Specifications 11364/04 and 15796/04.
