Title: Locking system for a kissing gate with an override position allowing gate to be completely opened
Inventor: GODDARD CHRISTOPHER DANIEL JOHN
IPC: E05B15/02
Filed: 2009-07-03
Abstract: A one way ratchet mechanism for a kissing gate bolt 2 comprises a rotating cog which is permitted to travel in one direction but prevented from traveling in a second direction by a pawl 1, the gate bolt can be retracted in order to bypass the cog by means of a key. During normal use the kissing gate swings between two gate posts and is retained by the one-way ratchet mechanism. To open the gate beyond the gate post to allow free access through the gate to allow the passage of wheelchairs and scooters the striker 2 is retracted with the use of a RADAR key in the form issued by the Royal Association for Disability and Rehabilitation; when the striker is retracted it can bypass the kissing gate latch and the gate can move to the completely open position. Upon removal of the key the striker 2 extends once more; the gate is biased to its closed, normal operation position, for example by self-returning hinges or springs and the one way ratchet permits passage of the strike bolt 2.

Filed: 1927-04-12
Abstract: 293,495. Carpmael, W., (I. G. Farbenindustrie Akt.-Ges.). April 12, 1927. Alkali nitrites are converted to nitrates with air or oxygen at temperatures of about 300-500‹ C. by using a catalyst such as an alkali hydroxide, an alkaline earth oxide, or a eutectic mixture of potassium and sodium hydroxides which melts at 180‹ C. In carrying out the process either the catalyst or the nitrite is liquified, the finelydivided nitrite or catalyst respectively distributed through the molten mass, and oxygen &c. bubbled therethrough. With a melt of potassium nitrite and hydroxide, the conversion may be effected at 360‹ C.; whilst with a melt of potassium nitrite containing calcium oxide, a temperature of 500‹ C. is necessary.

Abstract: 1276764 Optical waveguide WESTERN ELECTRIC CO Inc 6 March 1970 [7 March 1969] 10754/70 Heading G1A [Also in Division G3] In an optical waveguide, means extending transversely across the waveguide are provided to scatter in planes normal to the means, optical energy incident thereon; and photo-sensitive elements are positioned to receive the scattered light so that the energy distribution across the transverse direction can be measured. The photosensitive elements may be of elongated form and be longitudinally disposed and have areas of predetermined ratio. Two arrangements each having a pair of such systems with the directions of their scatttering means at right-angles, may be placed at spaced distances along the guide, and scattering may be effected by a quartz thread across the guide. The measurements are used to develop signals whereby lenses giving rise to an undesired distribution are redirected and refocused. The lenses may be of the thermal gaseous type, redirection being effected by servo movement and refocusing by thermal control. The use of groups of three or four photo-sensitive elements is discussed and a system in which each of the middle two of four have half the area of the outer two is said to give more accurate centering.

Abstract: 1464658 Pedestrian controlled vehicles POST OFFICE 6 March 1975 [12 March 1974] 11051/74 Heading B7H [Also in Division F2] A pedestrian controlled vehicle includes a variable ratio hydraulic transmission which is controlled in response to the effect applied by the operator to a control handle of a control means, the control means having a null state in which the transmission is hydraulically locked. The vehicle is powered by an I.C. engine 16 which drives a variable displacement hydraulic pump 18 connected in parallel to two wheel mounted motors 32. The control handle includes an operator's handle 26 telescopically mounted in a member 56 which is mounted by lug 58 on a vertically pivoted wheel thus permitting steering of the wheel by the handle. The operator's handle carries a block 64 slidable in a slot 66 of member 56 and centred by springs 78, 80, the block being connected by the core of a Bowden cable to a variable displacement control 86 on the pump. Pump displacement is normally set to zero so that motors 32 are not operated until handle 26 is pushed or pulled whereupon the displacement control 86 is varied depending on the effort applied. The vehicle is driven in a direction to re-centre the block 64 so that motion stops soon after the effort ceases. The hydrostatic transmission circuit includes a makeup pump 38 and a pump by-pass valve 48 which may be associated through a switch 54 with wheel brakes so that when the brake is operated fluid supply to the motors is cut-off. The parallel arrangement of wheel motors 32 allows for differential action of the wheels.
