Title: A fastening for a road vehicle bonnet cover, boot cover or for other analogous purpose
Inventor: BATCHELOR MALVERN ARTHUR
IPC: E05B65/19
Filed: 1952-09-08
Abstract: 735,445. Catch fastenings. WILMOTBREEDEN, Ltd. Oct. 27, 1953 [Sept. 8, 1952], No. 22489/52. Class 44. [Also in Group XXXII] A fastening for a road vehicle bonnet cover, boot cover or the like comprises the combination of a striker a adapted to be mounted on the bonnet cover or like part, a pivoted latch d having a pair of notches i, j at one side adapted for engagement by the striker in two successive positions, resilient means e urging the latch in a direction to engage the notches with the striker, additional resilient means for imparting an initial opening movement to the bonnet cover and means operable from a distant point whereby the latch can be moved only sufficiently to disengage one of the notches j from the striker and thereby permit the striker to move into engagement with the other notch i under the action of the additional resilient means, the disengagement of the other notch i from the striker being effected through the opening beneath the bonnet cover. As shown the latch d is mounted in a housing c so as to extend through an open side, the latch having a square section boss f between which and the walls of a substantially square recess g, are positioned the resilient means e consisting of four cylindrical rubber members forming with the boss f and recess, a pivotal bearing for the latch. The upper part of the latch has an inclined portion h engaged by the striker when it is moved downwardly to move the latch from its path. The rubber cylinders e are distorted by this movement of the latch and restore it to its position when the striker has passed, to latch the striker in position. The latch is released from a distance by a flexible wire p, the movement of which is limited so that when the striker is released by the notch it becomes engaged by the notch i. The striker is raised to the notch i by a keeper k which is pivotally mounted and resiliently loaded in the same way as the latch. Movement of the striker from notch j to notch i allows sufficient movement of the bonnet to enable a hand to be inserted to release the striker from notch i. In a modification the keeper is omitted and a helical spring is added which surmounts the striker and bears on a plate also carried by the striker. This plate, when the striker is engaged by the latch, bears on the top of the latch casing-with the spring compressed. Specification 652,266, [Group XXXII], is referred to.

Title: Gasification of solid carbonaceous fuels
IPC: C10J3/46
Filed: 1959-07-01
Abstract: 879,275. Gasefying solid carbonaceous fuels. INLAND STEEL CO. July 1, 1959 [July 8, 1958], No. 22572/59. Class 44 (1). Solid carbonaceous fuels in particulate form are gasified by forming at least two streams of the fuel in an oxygen-rich gas, one stream containing sufficient oxygen to effect complete combustion of a substantial part of the carbon in its fuel to carbon di-oxide with a high flame temperature and the other, or at least one other, stream containing only sufficient oxygen to effect incomplete combustion of part of the carbon in its fuel to carbon monoxide with a lower flame temperature, the two streams of fuel and oxygen-rich gas being introduced at spaced points into a combustion zone maintained at substantially atmospheric pressure so that the streams intermix in turbulent flow and react to produce a gas containing carbonmonoxide and hydrogen and less than 10% and preferably less than 5% carbon di-oxide. The oxygen-rich gas may be free oxygen or a gas containing at least 85% oxygen and the flame temperature of the two streams may be between 3200 and 4200 F. and between 2700 and 3000 F. In the higher temperature stream about 35-85% by weight of the carbon is combusted to carbon di-oxide while in the lower temperature stream about 65-85% of the carbon is converted to carbon monoxide. The solid carbonaceous material may be coal, lignite, peat, coke or oil-bearing shale. In the apparatus shown in Fig. 1 the fuel/ oxygen-rich gas mixtures are introduced as two diametrically opposed streams. Steam may be added through a line 19 and slag and product gas are withdrawn through lines 18 and 16 respectively. The streams may be introduced through a series of nozzles, e.g. of 6, 10 or 14 nozzles, arranged in opposed pairs or through a pair of nozzles arranged at rightangles to each other.

The cutter heads 44 are mounted on a hinged support plate 32, The stator of the motor performs damped oscillatory movement within the casing to minimize the vibrations transmitted to the casing. The motor 21 is mounted on a support member 65 connected, by straps 94, 95, to the mounting block 91 secured to the casing by a screw 106. On removal of the screw 106, the cutter head assembly, the support member 65, the motor 21 and the mounting block 91 can all be removed from the casing as a single unit.

Abstract: 815,807. Vehicle power steering. DOWTY EQUIPMENT Ltd. Oct. 23, 1957 [July 24, 1956], No. 22885/56. Addition to 684,974 [Group XXXIII]. Class 79(5) In a servo steering system for an aircraft retractable nose or tail wheel, a servo control member giving a fixed orientation of the wheel before retraction is automatically selected as the load is released from the shock absorbers when the aircraft becomes airborne. In an example the servo control device comprises a drum switch 37, Fig. 1 actuated by the rudder bar 42 and connected to solenoids 53. 54. Fig. 2 of a hydraulic reversing valve 52 controlling the steering motor 24. The rudder bar 42 is connected through a push rod 41 to a contact arm 92 which moves over opposed arcuate contacts 80, 81. mounted on an insulating plate 95 in the switch 37. Follow up is provided by coupling the plate 95 to the steerable leg component 14 through torsion rods 31, 36 interconnected through flattened portions 33, 34 when the wheel is in the lowered position. The rods 31, 36 are illustrated diagrammatically in Fig. 2 by arm 45 and push rod 46, Fixed orientation control of the servo system is provided by a fixed contact arm 93 which engages a further pair of opposed arcuate contacts 82, 83 on the drum switch 37 and is automatically brought into circuit by a contact A2 on switch A as the load is released from a spring finger 43 when the wheel 19 is relieved of ground load. Steering selection is provided by a pilot operated switch D which is coupled to a solenoid 60 of a selector valve 59 controlling a by-pass valve 62 connected across the steering motor 24. The switch D is short-circuited by a contact A1 on the switch A so that the valve 62 is maintained closed for fixed orientation. The electrical circuit for steering is broken by a trip switch C when the wheel is fully retracted and may also be broken by a cam operated switch B which limits the steering range. A further device to prevent retraction of the wheel before it is centralized comprises fixed contacts 97, 98 engageable with an arcuate conductor 96 on the rotatable plate 95 of the switch 37 and connected in the retraction control circuit.

Classes 38 (2) and 38 (4) An arrangement for starting and operating a hot cathode electric discharge lamp 1 comprises a three-limbed transformer core 12 upon the centre limb 12' of which is disposed a choke winding 5 and upon the two outer limbs 12<SP>1</SP>, 123 of which are disposed two respective secondary windings 8, 9; 10, 11 and the two respective parts 6, 7, unequally divided as regards numbers of turns, of the primary winding; the secondary windings are connected one across each lamp electrode 2, 3 and are auto-connected to the primary winding ; the choke winding is connected to an alternating supply 4 in series with the parallel combination of the lamp and transformer primary winding ; and these connections and components are so arranged that when current flows in the primary winding the flux due to the difference in the numbers of turns of the primary winding parts acts in the same sense or alternatively in opposition to the flux due to such current flowing through the choke winding, which results in the primary winding voltage at starting being less than, equal to, or greater than, that of supply 4, as desired. Each secondary winding may also comprise two parts, dis posed one part on each outer limb. Thus part 6 of the primary and part 8 of one secondary winding may comprise a single tapped winding on one limb 12<SP>1</SP>, the other part 7 of the primary and one part 11 of the other secondary winding may comprise another such winding on the other limb 12<SP>3</SP>, and the parts 9, 11 may be separate windings. Some or all the windings may have tappings, e.g. to vary the difference in the numbers of primary turns in the two parts. The circuit may include a P.F. correction condenser 13.
