Abstract: 428,923. Protective cut-out arrangements. FELTEN & GUILLEAUME CARLSWERK AKT.-GES., M³lheim, Cologne, Germany. Dec. 21, 1934, No. 36676. Convention date, Dec. 29, 1933. [Class 38 (v)] In a protective arrangement in which a fault-current coil a is connected at one end to earth and at the other end to a protecting conductor connected to apparatus in which dangerous voltages may arise due to failure of insulation or other causes, and in which a testing device is provided by means of which the coil can be temporarily disconnected from the protecting conductor and connected to individual phases of the supply, the coil a is connected to a contact spring d which is normally pressed against a fixed contact c connected to the terminal b of the protecting conductor by means of a spring- controlled two-armed switch lever e pivoted at f, the lever e normally engaging an abutment g in electrical connection with the contact c, so that there are normally two contact devices in parallel between the coil a and terminal b. The pivot f is also connected to the coil a through a resistance l. When it is desired to test the arrangement, the lever e is rotated in a clockwise direction, thereby disconnecting the coil from the terminal b of the protecting conductor and connecting the coil through the resistance l and a second lever n to one of the terminals p, q, connected to the phases of the supply.

Title: Improvements in door sealing means
IPC: E05C9/06
Filed: 1938-12-17
Abstract: 522,813. Doors. YOUNG, W. Dec. 17. 1938, No. 36797. [Class 20 (iii)] [Also in Group XXXIII] A door 1 is rendered gas-, weather-, flame-, and water-tight by means comprising a flexible sealing-strip 14 and a plate member 17 secured to the door, and a flange 24 and a rigid projecting member 29 on the door frame, the parts being so arranged that, when the door is closed, the plate member contacts with the flange thereby preventing the spread,of flames, and the sealing-strip is compressed by the member 29. In the construction shown, the strip is mounted between the member 17 and an angle member 16 both of which are secured to the marginal flange 15 of the door. The member 17 has a curved inner portion 21 the free edge of which contacts with the side of the flange 24 when the door is closed. The strip is normally spaced from this portion 21, but when the door is moved to the closed position it is deflected by the projection 29 and thereby moved into firm contact therewith. In a modification, the member 17 is flat and in a further modification the member 17 is extended and so arranged that, when the door is closed, it overlaps the flange 24 and bears against the outer edge thereof. The holes in the hinge butts of the door are of greater diameter than the pins on which they are mounted, and are also elongated in a diretcion at right angles to the plane of the door. By this means, the door can move bodily in its own plane and also in a direction at right angles thereto. To ensure that the door will be correctly positioned when closed, it is supported in this position by a sillattachment 32 having an inclined upper surface. The bulkhead door shown in Fig. 1 is fitted with the locking-mechanism described in Specification 511,732, [Group XXV].

Abstract: 1341686 Digital computers BURROUGHS CORP 31 July 1970 [13 Aug 1969] 37088/70 Heading G4A A central data processor 11 polls a number of terminal stations 23 in address sequence and each terminal 23 can have its address changed by itself or by the central processor, for example, so that an urgent request can be dealt with out of normal sequence or so that a terminal station is not interrupted. The system.-The processor 11 is a digital computer, having input/output devices 13 to 21, connected via communication link 22, e.g. a telephone line, to a number of terminals 23. Each terminal includes a digital computer which performs its own operations off line and communicates with processor 11 for message transfer. The system may operate in real time (on line) for a commercial application. The terminal (Fig. 2, not shown).-This comprises a computer having a read only memory holding microinstructions, a magnetic disc memory, a keyboard and a printer, a line discipline processor (preferably a digital computer) and a buffer store connected to line 22 via a modem 25. This is a modified version of the terminal described in U.S.A. Specification 3,564,509. Operation.-The processor 11 can send a poll inquiry message to each terminal inquiring whether the terminal has a message to send or a select inquiry message indicating that the processor 11 has a message to send. If the terminal cannot receive the message, e.g. it is operating off line, its line discipline processor sends a not ready message to processor 11. The latter either retransmits its message or polls the next terminal in sequence. Although the system operates in a multi drop mode, i.e. all terminals and the processor receive all messages sent, only messages with the correct addresses are responded to. When a terminal changes its address it notifies the processor 11 and changes to an address preferably different from that of the other terminals. In one embodiment the poll enquiry and select enquiry addresses may be changed independently and in another a terminal may have an additional address for a broadcast mode where a number of terminals have the same address. Other features include parity checking and serial data transfer.

Title: Trim Disconnect Device for an Aircraft Control System.
IPC: G05D1/00
Filed: 1967-08-14
Abstract: 1,159,742. Automatic control of aircraft. BENDIX CORP. Aug. 14, 1967 [Sept.2, 1966], No.37182/67. Heading G3R. In a system in which an aircraft control surface and its trim tab are controlled by an electricalautopilot, manual over-ride of the movement of the control surface automatically disables automatic control of the trim tab. In Fig. 3, signals from a radio beam approach receiver 2 and a pitch rate gyro 4 are applied to a servosystem 8 controlling an aircraft elevator 10. The signals are also applied to another servosystem 12-18 adjusting an elevator trim tab 22 in the opposite sense to cancel the moment about the elevator hinge. Adjustment of the elevator can be overridden manually by operation of a control stick 24 and a signal corresponding to the force applied is produced by a detector 30 and applied to a phase sensitive amplifier 32 so that when the force exceeds a predetermined value in one sense or the other, a relay 34 or 36 is operated to prevent undesirable movement of the trim tab in the same sense by opening the appropriate switch 14 or 16. If desired, movement of the trim tab in one sense or the other can be prevented by manual operation of a switch 46 to energize a relay 48 or 52. In one modification, movement of the trim tab is prevented in both senses when the force exceeds a predetermined value in either sense, and in another modification the predetermined value is dependent on the magnitude of control signal E 3 . Application to surfaces controlling the aircraft about other axes is referred to.

Abstract: 1420590 Endless conveyers COULTER ELECTRONICS Inc 27 Aug 1974 [27 Aug 1973] 37391/74 Heading B8A A system for passing sample cup holders 15 having a steel strip 52 through a sampling station 14 comprises a magazine 10 having a movable magnetic plate 36 which transfers the holders to an endless conveyer 13 from which the holders are discharged on to a stationary magnetized plate 54 of a magazine 12. The plate 36 is raised and lowered by a cylinder 42 and coacts with pairs of pawls 14 engageable with the holders 15. For discharging the holders, a pusher mechanism 56 includes a pusher head 74 snap-fittingly attached to rods 70, 72 of a vertically movable cylinder piston-rod 66. Lowering of the magnetic plate 36 causes holders 15 to be carried downwardly, the pawls 44 below the holders pivoting downwardly for passage of each holder. When the plate is raised, the pawls prevent the holders from being carried upwardly. With the plate 36 in its lowermost position the conveyer is indexed towards the station 14 and the magazine 12. Due to the sliding engagement between the plate 36 and the holders no harm occurs to an operator's hand inadvertently inserted below a holder. A limit switch initiates raising of the discharge pusher 56 but if the operator inserts a finger beneath the head 74 when the pusher is lowered, injury is avoided by snapping loose of the head 74, Fig. 7.

Title: Catalyst for removing oxygen from gaseous mixtures
IPC: B01D53/46
Filed: 1961-10-19
Abstract: In a process for removing oxygen from a gas mixture which contains hydrogen and oxygen in a volume ratio of 2 or more, a catalyst is used containing Ni or Co and Cu on a porous carrier together with an oxide of thorium and/or uranium. Examples describe the removal of oxygen impurity from hydrogen-nitrogen mixtures intended for ammonia synthesis.ALSO:A catalyst comprises a porous carrier on which is deposited, in finely divided form, nickel or cobalt, copper and at least an oxide of thorium or uranium, the amount of Cu and Ni or Cu and Co being not more than 1%, the amount of thorium oxide when present alone and calculated as Th being not less than 0,4%, the amount of uranium oxide when present alone and calculated as U being not less than 0,%, and the combined amount of thorium oxide and uranium oxide when both are present being such as to have the same effect as either at least 0,4% thorium oxide and at least 0,1% uranium oxide when each is used alone.  The catalyst may be made by impregnating the porous carrier with salts of the metals which are subsequently decomposed to the corresponding oxides and the Ni or Co and Cu are reduced to metals by heating at 200-300  DEG C. in the presence of hydrogen.  Specified carriers are pumice, Al2O3, active carbon and silica gel.  Comparative examples are given.

As shown, a mixture of, for example, p-xylene and m-xylene is placed in container 1 and subjected to a pressure of 550 kgm cm<SP>-2</SP> at 9.7‹C. Seed crystal of p-xylene is placed in container 6 at the same pressure. The seed crystal is transferred to container 1, through valve 9, and the pressure gradually increased substantially isothermally to 2900 kgm cm<SP>-2</SP> by acting on member 3 to reduce the free volume within the container. The liquid phase may then be removed, through valve 8 to container 4. Crystals of over 99% pure p-xylene are obtained. In another example, a mixture of benzene and methyl red was solidified at a pressure of 800 kg cm<SP>-2</SP> and 25‹C and then allowed to liquefy isothermally by gradually reducing the pressure. When 20% of the crystalline material had liquefied, 99.2% of the methyl red was found to be in the liquid phase. Reference is made to the use of the method for separating optical isomers and isotopes of hydrogen and uranium.
