Title: Improvements in multi-ported control valves for use in connection with sterilizers or disinfectors
IPC: F16K11/083
Filed: 1936-06-18
Abstract: 476,892. Disinfecting - chambers. GREVILLE, E. G., and HICKMAN, F. C. June 18, 1936, No. 16988. [Class 81 (i)] [Also in Group XXIX] A sterilizing or disinfecting apparatus is provided with a plug cock which by being rotated in one direction successively effects the evacuation, the steaming or sterilizing and the airing, by means of filtered air, of the sterilizing-chamber. As shown, the cock casing has three upper ports 14, 16, 18 respectively connected to a steam supply pipe 20, the discharge side of an ejector 22 connected to the sterilizing-chamber, and directly to the sterilizing-chamber. Two lower casing ports 15, 17 connect with the ejector inlet and a drain respectively, whilst an intermediate port 19 leads through a pipe 27 to a filter. The plug 2 is divided by helical partitions 30 into compartments of which those marked 33, 37, 41, 44 respectively have sets of ports 31, 32 ; 34, 35, 36 ; 38, 39, 40 ; and 42, 43. The ports of each set are located at different levels and angularly spaced relative to one another. By rotating the plug clockwise from an " off " position in which the sterilizing- chamber is connected to atmosphere through the filter the sterilizing-chamber may in turn be put under vacuum, connected to the steam supply, connected to the drain, placed under vacuum again and finally connected to the atmosphere so that air is drawn through the filter into the sterilizing-chamber by means of the ejector.

Abstract: 146,150. Submarine Signal Co., (Assignees of Fay, R. D.). June 27, 1919, [Convention date]. Detecting subaqueous sounds; locating subaqueous sounds.-A submarine sound receiving- apparatus consists of a number of microphones or other sound-receivers carried by a body adapted to be towed behind a moving vessel or to drift from a ship or other station. The supporting body comprises a number of hollow members of streamline form to reduce water noises each containing a microphone, the members being spaced apart (so that the binaural method of estimating the direction of sound may be used) and connected together by ribs or struts of stream-line cross-section. A compensator of the kind described in Specification 138,644 may be used to adjust for difference in time of receipt of the sound by the different receivers. As described, the towing cable e' containing the requisite leads is passed to the interior of a stream-line member C to which the members A<1>, A<2>, A<3> containing the microphones E are connected by ribs D, D<1>, the leads to the microphones being carried through tubes d<2> within the ribs. A solid float B of wood is connected to the member C by a rib D<2>. A clamp e<5> secured to the cable e<4> bears against the interior surface of the member C. Members A<1>, A<2>, A<3> have perforations a<1> admitting water to the interior of the arrangement, and, together with member C, are made in two parts a<2>, a<5> to allow access to the interiors. A strut may be provided between members A<1>, A<2>. The whole structure is preferably of wood, with metal protecting strips along the leading edges of the ribs. Metal plugs f may be inserted to adjust the buoyancy and trim of the arrangement. The microphones E which are shown as spaced apart so as to lie at the corners of an equilateral triangle, are placed within rubber tubes which may be kept in place by external ribs on the tubes or by rubber sponge fitting the chambers in the hollow members, and serving to protect the microphones from lateral sounds.

Abstract: A hydrocarbon motor fuel contains as an inhibitor of gum formation a composition comprising N : N1-di(sec.-butyl)-p-phenylene diamine and a phenol, the phenol being present in amount corresponding to about 5-30 per cent. of the weight of the N : N1-di (sec.-butyl)-p-phenylene diamine.  Suitable phenols are phenol itself, p-cresol, tert.-butyl catechol, p-isopropyl phenol, 2 : 4-dimethyl-6-tert.-butyl phenol, p-tert.-butyl phenol, p-amyl phenol, p-octyl phenol, p-stearyl phenol, a-naphthol, o- or p-aminophenol, N-phenyl-p-aminophenol, N-benzylp -aminophenol, N-cyclohexylp - aminophenol, and the N-alkyl-p-aminophenols, a number of which are specified.  The hydrocarbon motor fuel may contain other ingredients such as appreciable quantities of alcohol or other combustible materials and tetra-ethyl lead or other tetra-alkyl lead compounds. If desired the gum-inhibiting composition may be introduced into the fuel by adding it to an anti-knock composition which is subsequently added to the fuel, the anti-knock composition comprising a tetra-alkyl lead compound and a halogenated hydrocarbon such as ethylene dibromide or ethylene dichloride or both.  Specific gum-inhibiting compositions mentioned in the examples are N : N1-di(sec.-butyl)-p-phenylene diamine together with N-(n-primary-butyl)-p-aminophenol, o-cresol or 2 : 4-dimethyl-6-tert.-butyl phenol.

Title: Locking device for a door
Inventor: WESTERLUND T
IPC: B66B13/04
Filed: 1974-04-22
Abstract: 1432914 Lift door locking mechanism LINDEN-ALIMAK AB 22 April 1974 [26 April 1973] 17464/74 Heading B8L [Also in Division E2] A locking device for a landing door 10 in a shaft up and down which a lift cage 11 moves, comprises an elongate lock arm 5 which tends to be displaced longitudinally of itself in one direction when door opening commences, the opening motion being prevented, when the door is to be locked, by a stop 7, on the arm 5 engaging a stationary shoulder 6 preventing longitudinal displacement of the arm 5, which is pressed by resilient means 8 into a shoulder engaging position, whereby the door cannot be opened. When the door 10 is to be unlocked, in the presence of a lift cage 11, longitudinal movement of the lock arm 5 resulting from opening movement of the door 10, causes the free end of the arm 5 to engage a locking track 9 on the cage 11 whereby the arm 5 rides up the track 9 against the resistance of the resilient means 8, and the stop 7 on the arm 5 passes over the shoulder 6 without engagement whereby the door 10 can be fully opened. The locking arm 5 is operated through levers 3, 4 secured to a shaft 1 pivotally mounted along the door opening top, the door, which may be hinged or slideable, being arranged to engage the lever 3. The resilient means 8 is associated with a switch 12 which is in a closed position unless the resilient means is deflected upwardly during door release, when the switch is opened to prevent power supply to lift cage drive circuit. Since there is a space between the stop 7 and shoulder 6, the lock arm 5 always moves a short way out into the lift shaft upon an initial attempt to open the door 10, before it can be engaged by the track 9. In the embodiment of Figs. 3, 4, 5 (not shown) the resilient means moves arcuately sideways between end positions.
