Title: A regulating device for regulating exhalation gas flow in an exhalation conduit of arespiratory apparatus
IPC: A61M16/20
Filed: 1966-09-29
Abstract: 1,124,699. Respiratory regulating apparatus. O. H. DRAGER [trading as DRAGERWERK, HEINR, & BERNH. DRAGER]. 29 Sept., 1966 [29 Sept., 1965], No. 43678/66. Heading AST. [Also in Division F2] A regulating device, for regulating exhalation gas flow in an exhalation conduit of a respiratory apparatus for anaesthetizing, consists of a housing 2 divided into chambers 8, 10 and 12 by two walls 5 and 6. both of which walls have apertures therein for receiving, in sliding engagement, an internally threaded sleeve member 13. An externally threaded spindle 14, mounted in this sleeve; has attached to one of its ends a rod 15 carrying a member 17, for closing aperture 3, and a hand wheel 16, for turning the spindle within its sleeve. At the other end is mounted a rod 18 carrying, in slideable engagement, a closure disc 19 for abutting valve seat 23 and hence closing duct 4. Compression springs 20 and 25 tend to retain the device in the position shown. A pressure responsive membrane 7 is firmly attached to both the housing 2 and sleeve 13. A patients breathing organs are connected to duct 4 and hence through members 12, 11 and 10 to a negative pressure line 1. If greater resistance to exhalation is desired, the wheel 16 is rotated so raising member 17 and opening chamber 10 to atmosphere. Further rotation in the same sense would result in member 19 abutting seat 23 with a force which would be dependant on the loading on spring 20 as applied by the spindle. If the resistance is to be increased still further, a controllable positive pressure pulse may be applied through duct 9 to act on the membrane 7. Thus, by suitable rotation of the spindle supplemented by positive pressure pulses, the patients breathing organs may be subjected to a range of pressures extending from negative to positive valves.

Abstract: 1,066,248. Polarographic apparatus. METRIMPEX MAGYAR MUSZERIPARI KULKERESKEDELMI VALLALAT. Nov. 6, 1963, No. 43868/63. Heading G1N. A voltage supply circuit for a polarographic cell 8 comprises a double triode 3 having a first grid 4 connected to a controllable voltage source 1, and a D. C. amplifier having its input connected to one of the anodes of the double triode and its output connected to unearthed electrode 9 of the cell, the second grid 12 of the double triode being connected either to the output of the D. C. amplifier, as shown, or to a reference (Calomel) electrode in the cell Fig. 2 (not shown). The position of slider 2 of potentiometer 1 controls the unwinding of a paper strip in a recording device. Since no current is drawn from slider 2 the internal resistance of the system does not influence the voltage applied to cell 8, and similarly differences in the cell resistance do not affect the voltage supplied by potentiometer 1.

Abstract: 1361806 Control devices AMP Inc 5 Sept 1972 [23 Sept 1971] 44312/71 Heading G4H A remote switching system for controlling electrically operated devices 28, distributed around a car, from manual switches 1 located at the driving position comprises an encoder 7 coupled to each switch 1 via crossed inverters 2 and bi-stables 4 and to decoders 19 by a cable 14, each decoder 19 in turn being coupled to a bi-stable 21 and a transistor-controlled switch 26, 27 operative to connect or disconnect device 28 to a power line 29. Closure of a switch 1 sets bi-stable 4 and causes encoder 7 to output a binary signal indicating the required device. The respective decoder senses this signal and sets its bi-stable 21 whose output switches on a transistor in 26 so as to actuate a relay which closes switch 27. This procedure is repeated to open 27, bi-stable 21 then being reset. An oscillator 17 outputs pulses on a line 15 to the decoders controlling the flasher and hazard warning devices; here bi-stable 21 is connected to the direct set input of a toggle flip-flop 32 which transmits pulses received at input 33 to switch 26. The outputs from bi-stable 1 are fed back to their reset inputs via a delay 9 so as to avoid interference between switches. The inverters 2 eliminate contact bounce and encoder 7 incorporates rollover prevention circuitry.

Title: Adjustable pivotal joints
IPC: A47C20/06
Filed: 1960-12-28
Abstract: 949,976. Hinges. W. BAHMULLER. Dec. 28, 1960 [Dec. 24, 1959], No. 44395/60. Heading E2F. [Also in Division A4] A pivotal joint for a folding bed or other article comprises two pivot members 1, 2 (Figs. 2, 6) pivotally connected at 5, 7 respectively to a plate 6, the member 2 having a locking element 12, which co-operates with a counter member 10 on the member 1 to lock the joint in various positions, and a supporting surface 13 which, during pivotal movement, slides along the inner or outer face of a contact surface 14 on the member 1. When applied to a folding bed the members 1 and 2 constitute the central portion and head rest, respectively, and a leg member 3 is pivotally connected at 4 to the member 1. In the folded position the members 2 and 3 lie parallel to the member 1 as shown in chain-dotted lines in Fig. 2. To unfold the bed the leg member 3 is first swivelled to its operative position, slightly beyond the vertical, and the member 2 is then rotated in an anti-clockwise direction and turns about the pivot 7 until its supporting surface 13 strikes a lug 16 of a control lever 8 pivotally mounted at 5. The control lever cannot rotate in the clockwise direction owing to a stop 17 on the member 1, and consequently the rotation of the member 2 about the pivot 7 is arrested and the member, together with the plate 6 and control lever 8, begins to turn about the pivot 5, the supporting surface 13 passing inside the contact surface 14 on the member 1 while the locking element 12 remains clear of the counter member 10. On approaching the lowest position of use a lug 19 on the control lever 8 abuts a stop 18 on the member 1 and the member 2 then rotates again about the pivot 7 to bring the locking element 12 into engagement with the member 10. The member 2 can now be rotated upwards again, and rotates firstly about the pivot 7, until the surfaces 13 and 14 abut, and then about the pivot 5, re-engagement of the locking element with the member 10 being obtained by exerting a slight downward pressure on the member 2. Should a person sit on the member 1, thus sharply tensioning the fabric overlay (not shown) the tendency of the member 2 to swing sharply in a clockwise direction will be arrested by the engagement of the surfaces 13 and 14. The plate 6 is provided with an arcuate edge portion 21 which engages a corresponding groove 20 in the leg member 3 to lock the latter in its operative position, the engagement taking place while the member 2 is being rotated from its folded to its operative position. In the embodiment shown the locking element 12 is formed on the two lateral walls of the member 2 and two counter members 10 and plates 6 are provided, but it is possible for some purposes (e.g. display stands) to have two members 2 or 3 each having only one locking element 12 or groove 20 respectively. In a modification, Fig. 5, the separate counter members 10 are dispensed with, the side walls of the member 1 being inwardly recessed at 10<SP>1</SP> to make wedging engagement with the correspondingly shaped locking element 12.

The shaft 18 is keyed at 20 to the rotor 16 and is formed with a squared portion 38 by which the rotor may be moved manually. A plate 36 indicates the position of the rotor 6. The movement of the piston 44 may be controlled by a remote valve instead of the valve 54.

The bushes 22, 23 shown closed at their ends, adjacent the bottoms of the bores are formed with necks 37, 41, Fig. 2, surrounded by the sealing rings 38, 42, with the necks shaped so that their profiles are nearest the bored peripheries adjacent the pump inlet 9. The closed ends of the bushes 22, 23 and the spaces within the rings 38, 42 are connected to the pump inlet 9 whilst the space 43 surrounding the rings is connected to pump delivery. The positioning of the necks and the areas of the spaces within and outside the sealing rings is determined so that the pressures acting on the ends of the bushes overcomes the graduated pressure between the pump inlet to the pump outlet acting on the faces of the bushes adjacent the gears to urge the bushes without tilting into sealing engagement with the gears.
