Title: Device for protecting against unexpected, sudden penetration of water into spaces ofall kinds, especially ships' holds
IPC: B63G8/04
Filed: 1935-02-18
Abstract: 437,862. Door-operating appliances; conning-towers. SCHWEFEL, J., 15, Schuttelstrasse, Vienna. Feb. 18, 1935, No. 5218. Convention date, Feb. 16, 1934. [Class 113 (ii)] [See also Group XXV] Doors closing the compartments of ships are provided with a plurality of independently - operated devices for releasing the member holding the door in open position as soon as an inrush of water occurs. As applied to a conning-tower provided with a pair of interconnected doors, a float 17 enclosed in the chamber 6 provided with water inlet holes 8, 12, operates when flooded with water a centrally - disposed rod 19 which through the bell-crank lever 25 actuates the lever 29 mounted on the spindle 28 with the catch 30 holding the door 4 in open position. The door 4 is interconnected with the upper door 5 through the lever system 34, 33, 35 and the lever 37 connected with the hub 38 mounted on the axle 3 of the second cover. Around the upper part of the tower are arranged electric contacts 45 separated by an insulator 44 and internally connected by the contact strip 48 which is connected by the lead 46 with an electromagnet 47. In a chamber 51 surrounding the upper part of the tower is mounted a ring-float 54. The doors when open may be thus independently shut on inrush of water (a) by the use of the float 17 and mechanical release of the catch 30 (b) by the salt water completing the electrical circuit and thus activating the solenoid 47 with attraction of the lever 29 and release of the catch 30 (c) closure of the electrical circuit by the rise of the float 54 in the chamber 51. Arrangements are provided for allowing the independent opening of the doors. The spring catch 70 for the upper door is connected by the wire 42 with an arm 73 on a right and left-hand screwed spindle 41. The swinging movement of the catch on opening the door thus causes the separation of the arms 43 mounted on the spindle 41 and consequent opening against the action of a spring of the elements 39, 40 of a clutch mounted on the axle 3 of the upper cover. In a modification, the cord 42 may be caused to retract a pawl normally locking a ratchet wheel on the axle of the door.

Patent GB-429386-A (GB)
Title: Improvements in or relating to telephone systems
IPC: H04Q3/58
Filed: 1934-02-19
Abstract: 429,386. Automatic exchange systems. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London, MOSS, B. F., and CARPENTER, O. I., c/o General Electric Co., Stoke, Coventry. Feb. 19, 1934, No. 5367. [Class 40 (iv)] In a district-office system in which a main exchange junction is seized on all calls and is released when the initial digit or digits denote a local call, the switch which seizes the junction subsequently responds to the final digit on local calls to select the ringing current to be applied to party lines. On the initiation of a call, line, release and dialling relays A, B, C energize and the switch CS operates in the usual manner to seize an idle junction, whereupon K pulls up. The first digit is repeated to the vertical magnet V of the local selector and over the junction, NA operating when the selector moves off normal, and if this digit denotes a main exchange call the relapse of C connects up JD which prevents subsequent digits from affecting the local selector. In the event of all junctions being busy, dialling tone is applied from the sub-normal position of CS, and busy tone is applied by JD if the first digit indicates a main exchange call. If on the other hand the first digit does not determine the nature of the call, the relapse of C connects up LE over the vertical wiper VB and the release magnet Z operates to restore the selector. The second digit is effective in a similar manner, and if it is now determined that the call is a local one, the relapse of C connects up H over the vertical wiper VB and the selector again drops back. In the normal position NA falls back and connects up LD which disconnects the junction and causes the switch CS to advance to its subnormal position. The third and fourth digits operate the vertical and rotary magnets V, R, and relay E, which energizes in parallel with R, connects up ES, MD, so that when E relapses, the magnet of the switch CS is connected up to receive the final digit, which may be 1-4. Relay ES falls back at the end of this digit, releasing H and connecting up ringing relay F, ringing current of 16 or 50 cycles on one or other leg being applied according to the setting of CS. Should the wanted line prove busy, G operates on the relapse of E and sends back busy tone, H being held If the calling party requires another party on his own line, after receiving the busy signal he dials a further digit 5-0 dependent on the identity of himself and of the wanted party, whereupon RS energizes over wiper CS3 to hold the selector. Hanging up by the calling party causes the release of A, B, G and H and ringing relay F operates to ring the two parties alternately. Feed current is supplied to both parties over relays DA, DB.

Title: Electronic computer
IPC: G06F9/22
Filed: 1966-02-08
Abstract: 1,120,371. Microprogramme operations in a digital computer. G. E. OVSEPIAN, V. LEVONOVICH ADZHEMIAN, K. K. EILEZIAN, P. S. SAGATELYAN, and G. A. ORGANYAN. 8 Feb., 1966, No. 5423/66. Heading G4A. The invention is concerned with microprogramme operations in digital electric computers. A micro-programme can be used to provide checking means in a ferrite core register 2 which has individual cells checked using a micro-command having a constant. An AND circuit 21a connected to an address register 13 of a main storage means 3 analyses the presence of constants in micro-commands and via gate 21, enabled by a pulse generator 19, causes pulse shaper 20, which is a one-shot multivibrator, to enable the reading of the constants from block 10 of the memory via gates 30 to an adder 1 and at the same time allows elementary operation commands and a consecutive microcommand address to be read from block 11 of the memory. The constants under the command of the micro-programme, are read into the cell to be tested and are then read to the inverting terminals of the adder and added to the same constant preserved in the adder. The adder contents are zero checked and if they are non zero then the cell number is typed out. A similar check can be carried out on an immediate access memory 4. In this case the constant is read into all cells simultaneously and read under the control of a memory address counter incremented by a microcommand. The output of the cells is applied to the adder as before. Interruption of a micro-programme when reading a digit having an address held in a command register 28 can be performed. A pulse in the micro-programme triggers a pulse shaper 24 via gates 29a and input 40. The pulseshaper produces an inhibiting signal via gate 25 preventing further transfer of micro-commands to register 13 and an instruction signal via gate 26 causing transfer of a micro-command address to register 6 of the immediate access memory 4. This causes transfer of a digit address and a micro-command from register 28 to register 13. The next pulse from generator 19 causes readout of the digits held in the said address, and after passing through delay 18 resets register 13. Gate 22a detects the micro-command and triggers pulse-shaper 20 to enable gates 30 to allow the digit to pass to adder 1 and causes the transfer of a consecutive micro-command address from register 6 to register 13 via gates 16.

Title: Improvements in and relating to the manufacture of cellulose ethers
IPC: C08B11/20
Filed: 1929-02-20
Abstract: 333,902. Imperial Chemical Industries, Ltd., and Traill, D. Feb. 20, 1929. Cellulose ethers.-Aralkyl ethers of cellulose, particularly benzyl cellulose which are wholly or partially insoluble in the usual organic solvents are treated with benzyl chloride or other aralkyl halide and water and steam at increased pressure so as to improve their solubility in cheap solvents such as benzene toluene or xylene mixed with industrial spirits. The products so treated give solutions of reduced viscosity. The process may be carried out on benzyl cellulose which has been separated from the benzylation mixture or on the reaction mixture which may contain sufficient benzyl chloride for the further treatment. During the treatment with water and steam the benzyl chloride is hydrolyzed and the reaction thus effects purification of crude benzyl cellulose. The modified aralkyl celluloses give clear lacquers and may be employed in the manufacture of moulding powders, safety glass, artificial silk, celluloid, floor covering, plastic wood, and cable covering. In an example a benzyl cellulose mass containing 5-40 per cent benzyl chloride but preferably 20 per cent, is treated in an autoclave with 10-20 times its weight of water and with steam at a pressure nf 50 lbs per square inch for one hour. In another example sparingly soluble benzyl cellulose is treated with five times it weight of water containing 1 -5 per cent of benzyl chloride for 40 minutes in an autoclave under steam pressure of 50 lbs per square inch. The product is soluble in mixtures such as benzene spirits or xylene spirits and gives solutions of lower viscosity. Specification 327,714 is referred to.
