Title: Improvements in and relating to door lock mechanism
IPC: E05B65/32
Filed: 1956-12-14
Abstract: 841,326. Latches. ROETHEL, J. H. Dec. 14, 1956 [Feb. 17, 1956], No. 38192/56. Class 44 A door latch mechanism comprises a plate portion 10 Fig. 1, for disposition at the free edge wall of a swinging door and having a flange 12 extending from the inner edge thereof, a pivoted latch 14 mounted on the outer face of the plate portion 10, a lever means 20 pivotally mounted on the inner face of the plate portion on a common pivot with the latch, coupling means 18 connecting the lever means 20 to the latch 14, the lever means 20 having an arm 22 extending upwardly from the pivotal axis thereof, outer manually operable means for pivotally actuating the lever means and including a lever 24 pivotally mounted on the plate portion 10 and having a portion movable towards the flange 12 upon swinging of the lever, link means 32 pivotally mounted on the lever portion and having a part 34 arranged in operative relationship with a part of the arm 22 and being shiftable upon swinging of the lever 24 to cause the lever means 20 to swing, the coupling means 18 transmitting swinging movement of the lever means 20 to the latch to swing the latter from door-latched to door unlatched condition, and inner manually operable means to render the link means 32 ineffective. As shown operation of the lever 24 by a push button or handle (not shown) to release the latch, may be rendered ineffective by operation of a lever 41 Fig. 2 on the inside of the door, in a direction opposite to that in which the lever 41 is effective to move the latch to the unlocked position, the lever 41 being pivoted on the flange 12 and operated through a remote control mechanism (not shown). A stop 40, Fig. 1, prevents excessive travel of the link 32. The stop may be so positioned as to abut a part 39 of the link when the latter is raised by the lever 41 whereby to positively block operation of the outside handle or push button. The latch 14 co-operates with a keeper 50 comprising a lower part 52, Fig. 8, provided with two teeth 55, 56 for engagement with a projection 16 on the latch, and a spring loaded slidable wedge 58 against which a housing 13 for the latch slides as the door is moved towards the closed position. In a modification Figs. 5 and 6 (not shown) the lever means 20 comprises two super-posed bell crank levers pivoted independently about a common pivot axis and each engageable with the coupling means 18 to release the latch from the outside and the inside respectively and arranged to provide a positive blocking of the outside handle upon reverse movement of the inside handle.

Abstract: 1,075,185. Lasers. WESTERN ELECTRIC CO. Inc. Sept. 24, 1964 [Sept. 30, 1963], No. 38923/64. Heading H1C. A laser includes a gaseous active medium, and an auxiliary gas containing a significant proportion of He<SP>3</SP>. The active medium may be neon, xenon, or mercury vapour. The ratios of the partial pressures of the helium and neon may be between 3 to 1 and 50 to 1, preferably about 7 to 1. It is stated that the laser tube may be substantially smaller than in lasers using He<SP>4</SP>, a length of two inches and a diameter of one millimetre being possible. An arrangement for selecting weak modes from the laser consists of the provision of a dispersive reflecting element as one of the terminal elements of the optical cavity. The other end of the cavity may consist of a spherical mirror or a second similar dispersive element. The dispersive reflecting member in one embodiment (Fig. 5, not shown) consists of a prism having a plane refracting surface (59) upon which the laser radiation falls at the Brewster angle (#), and a reflecting surface (60) upon which a selected wavelength falls normally. The reflecting surface (60) may be coated with dielectric reflecting layers (61). In a second embodiment (Figs. 6A, 6B, not shown) the prism has a spherically curved reflecting surface and a cylindrically curved refracting surface (71), the laser radiation again being incident at the Brewster angle. The radius of curvature of the cylindrical surface is made equal to S -, where S is the radius of curvature of n cos # the spherical surface, n is the refractive index of the prism and # is the Brewster angle, whereby astigmatism is avoided.

As shown, the toothed locking wheel device 4 includes two coaxial locking wheels 4A, 4B, each formed with single action ratchet teeth, each presenting one steep ratchet face, the steep faces on the two wheels facing in opposite circumferential directions, the two wheels are approximately opposite respective abutments at opposite ends of the lead screw. In operation, when rotation of the driven shaft 2 is taking place between the ends of the range of movement permitted, the detent 10 moves along the lead screw 5 in one direction or the other depending on the direction of rotation of shaft 2; there is no interference between detent 10 and locking wheel device 4 because centring springs 11, Fig. 2, are provided. When the driven shaft has reached one end of its permitted rotational movement, detent 10 comes up against, e.g. abutment 9, so it must rotate thereafter with the lead screw, whereupon a pallet (e.g. 10A) engages a tooth of wheel 4A, thus locking shaft 1 against further rotation. In Fig. 3 (not shown) lead screw 5 is on a spindle geared to shaft 2.

Dec. 30, 1930, No. 39223. Convention date, Feb. 8. [Class 56.] Production of metal.-A luminous electric discharge tube having a cadmium vapour filling is made of a borosilicate glass which, in addition to boric oxide, alkalies, and alkaline earths, contains at least 10 per cent of aluminium oxide and less than 60 per cent of silica. Part of the silica may be replaced by oxides of rare earths such as the oxides of lanthamum or didymium, or a mixture of these oxides. The glass is not noticeably darkened by the cadmium vapour. A discharge tube made from this glass, when used in the open air, may be placed in a tube of ordinary glass in order to reduce the loss of heat by radiation and thus prevent condensation of the cadmium vapour. The outer tube may be made of glass which absorbs the infra-red rays, so that the radiation of these rays is changed into heat within the wall of the outer tube to raise the temperature of the inner tube. Specification 351,245 is referred to.

In a plate-type heat exchanger a plurality of parallel plates 11 which may be corrugated, are spaced by rigid means and each sealing element 16 is provided with a groove 16a in its inner periphery. The plates are all identical, alternate ones being reversed so that the spacing dimples 25, Fig. 2 (not shown), which are not symmetrically disposed, do not coincide with the spacing dimples 26 of a contiguous plate. Depressions 29 are formed in a ridge 30 surrounding each plate and further depressions 27 are formed at each end of the corrugations in the central portion 17. These depressions contact with undepressed portions of contiguous plates. Apertures 12, 15 in the plates are partly encircled by flanges 20 which flanges have depressed portions 21 and raised portions 22 respectively which portions act as additional spacing means. A depressed channel 24a allows any fluid seeping through the seals to escape thereby preventing intermixing.
