Title: A process for inhibiting galvanic corrosion of magnesium or magnesium alloy
Inventor: ADAMSON KEITH GEORGE
IPC: C23F11/18
Filed: 1968-03-29
Abstract: 1,207,434. Inhibiting bi-metallic corrosion of Mg. MAGNESIUM ELEKTRON Ltd. March 25, 1969 [March 29, 1968], No. 15144/68. Heading C7E. Galvanic corrosion of Mg or Mg alloy components electrically connected to electro-chemically dissimilar metals, both the Mg and other metal being electrolytically connected by means of water but in the absence of externally impressed current, is inhibited by adding a soluble chromate to the water, in the absence of a fluoride. The electrical connection may arise from the juxtaposition of Mg and a metal such as Fe, Cu, brass, or solder, e.g. in an I.C. engine with a Mg cylinder block, and the chromate used is an alkali- or alkaline earth-metal chromate, used in amounts of 0À1- 20 wt per cent.

Title: Improvements in or relating to magazine-locking means for type-bar making machines
IPC: B41B11/18
Filed: 1925-06-11
Abstract: 258,006. Allied Newspapers, Ltd., Skinner, D., and Woollen, T. A. June 11,1925. Distributing matrices; magazines.-The usual distributor-screw stop-mechanism is adapted to lock the magazines against movement, and the locking is also effected if the matrices are not completely delivered to the distributor, or if any matrices remain on the distributor-bar. The control lever f, Fig. 1, which in known manner locks the distributor-screws g<1>, g<2> when released by movement of the sliding partitioned plate h, Fig. 5, is connected through a link e and lever d with a sliding rod a. When the lever f is released, the rod a is projected through a hole in a bar b connected at one end to an arm on a rock-shaft c<6>, and at the other to the magazinechanging mechanism, which is thereby locked. The operation of the magazine-changing lever c, Fig. 6, necessitates the raising of a trip-lever c<3>. which acts through the known sliding segment c<4> on a bell-crank lever c<5>, which is connected by a link c<2> to the bar b. The magazines are locked in the event of a matrix line not being completely delivered to the distributor, by a sliding rod m, which is adapted to be projected by a spring s into engagement with a hole in a bar n, which is connected to an arm on the shaft c<6>. When the matrices are fully delivered by the pusher o, a pin r acts through a lever p to withdraw the rod m and release the magazines. If matrices remain on the distributor-bar, the shifting of the magazines is prevented by a sliding plate t, which is projected between the distributor-screws by levers w connected by links x to arms in the rock-shaft c<6>.

Title: Position indicator for vehicles
IPC: G01C21/12
Filed: 1944-08-09
Abstract: 580,195. Position indicators for vehicles. SCOPHONY, Ltd., and GALE, A. J. Aug. 9, 1944, No. 15183. Addition to 580,165. [Class 97 (ii)] In a position indicator according to the parent Specification and in which the extent of the to-and-fro movement produced by the log signals is predetermined by the reading of a magnetic compass, a correction for the magnetic deviation corresponding to the indicated position is fed back to the compass-driven shaft from the latitude and longitude counters. As shown, the magnetic deviation is represented in relief on a cylindrical cam 66, which represents the earth's surface on Mercator's projection. The cam 66 is fixed on the shaft 67 and the latter is rotated by the gears 71, 72 and shaft 72A connected to the longitude counter and is moved axially by the gears 70, 74, 73 and shaft 73A connected to the latitude counter, so as to bring the part of the cam 66 corresponding to the indicated position beneath a cam follower 66A. The shaft 1, shown also in Fig. 1 of the parent application, is driven by spiral gears 60, 61 from the compass-controlled shaft 62. The gear 61 is non-rotatable, but axially movable, on the shaft 62 and is pressed by spring 64 against a bearing 65 carried by the cam follower 66A. Thus the relief on the cam 66 can move the gear 61 axially on the shaft 62 and impart an additional rotation to the shaft 1. The spiral gears 60, 61 may be replaced by an epicyclic gear system. In a modification, the cam follower may be caused to move over the correction cam.

[Class 40 (iii).] To restore a light-sensitive cell more rapidly to the normal state after obscuration, e.g. by smoke in a ventilating system as described in Specification 376,381, [Group X], a temporarily augmented light source is automatically brought into use. When the cell 3 is obscured, the normal light source 2 may be supplemented by a source 1 brought into operation by the relay 4, 5. Alternatively a dimming resistance in the lamp circuit may be short-circuited, and if desired the total current from the lighting mains may be kept constant by simultaneously disconnecting a compensating load, Fig. 2 (not shown). In other modifications the relay moves a reflector, lens or iris diaphragm in such a manner as to augment the illumination falling on the cell. The relay may also adjust a ventilation system according to the pollution of the air in the space 6.

Patent GB-1166895-A (GB)
Title: Improvements in Gas Fires
Inventor: MA FRANCIS TIN CHAK
IPC: F24C1/14
Filed: 1967-04-04
Abstract: 1,166,895. Heating air for combustion; incandescent gas fires. GAS COUNCIL. 19 March, 1968 [4 April, 1967], No. 15340/67. Heading F4W. Some of the hot combustion products from a gas burner 5 in a gas fire are drawn by a fan 19 through a gas-permeable rear panel 3 of the radiant into a chamber 8 formed behind said panel and thence through a heat exchanger 16 in which combustion air for the burner is preheated. The unit is enclosed by a casing 1 which is open at the front (detail not indicated) for the emission of heat from the radiants, and for the discharge to a room or like of convected air heated on its passage through the casing. As shown, this air is blown downwardly by a fan 34 being guided en route by a deflector 36. Alternatively the fan may induce an air flow upwardly or, with the fan switched off, air flow is by natural convection. The radiant comprises front and rear ceramic panels 2, 3 having thorn projections 2a, 3a thereon. The rear panel 3 which may have thorn projections on both sides, has perforations 4 through its upper part. In use, some combustion gases pass upwardly between the radiant panels 2, 3 through a duct 28 and heat exchanger 29 to a flue 30. The remainder controlled by a baffle 25 are drawn by the fan 19, through the holes 4 in the rear radiant panel to the chamber 8 and pass thence through thin-walled tubes forming the heat exchanger 16, to a header 17, and thence via a duct 32 to a nozzle 33 in the flue 30 thereby inducing flow through the duct 28. Combustion air comprises a portion of the air delivered by the fan 34, this air being heated as it traverses the heat exchangers 29 and 16 en route to the burners 5. When the fire is operated at a lower heat output, the fan 34 is reversed or stopped to provide an upflow of induced or convected air some of which is preheated as it passes through the heat exchanger 16 to the burners. In this case also the damper 25 is turned to the position shown by dotted lines so that the combustion gases are withdrawn through the lower part only of the panel 3. The damper 25 may be operated manually, thermostatically, or in conjunction with the gas supply valve. At a still lower heat output the exhaust gas fan 19 may also be switched off and a damper 31 is then opened so that at least some of the resulting fume spillage from the radiants is directed into the exhaust duct 28. Flow of combustion of air is in this case assisted by opening a flap 37 in a chamber 6 containing the burners. The unit may in a modification, be adapted as a room-sealed unit. In this form, the radiants are closed by a glass plate 38 and the intake of the air fan 34 is arranged around the flue outlet 30 for connection to a balanced flue terminal.

IPC: B65B5/10
Filed: 1962-04-24
Abstract: 1,031,244. Reciprocating conveyers; packaging machines. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. March 26, 1963 [April 24, 1962], No. 15438/62. Headings B8A and B8C. Apparatus for filling a can 87 with pellets 88 end-to-end and in sequence comprises a reciprocating plunger 68, a pallet feed head 69 and a chuck 89 for gripping the can 87. A carriage 2 which supports the plunger 68 has parallel rods 11 slidable in a box structure 5 and is normally urged to a retracted position by springs 19. The carriage is reciprocated by a rotatable cam 28. A cross-bar 14 of the carriage carries a rod 34 provided with a piston assembly 36 which operates in a slidable cylinder 40. A plug 54 is fitted in the cylinder which has a chuck 67 formed integrally with it. The cross-bar 14 .also carries a microswitch 59 having an operating lever 60 which projects in the direction of a collar 44 carried by the cylinder 40. The collar is normally latched to the rod 34 by spring- urged balls 47 which engage with a circumferential groove 51. An air passage to and from the cylinder is provided by drillings 62, 63 in the piston assembly 36, a bore 61 in the rod 34, a drilling 66 in the carriage cross-bar 14 and a pipe 64. A piston-rod 33 of an air cylinder 32 engages the cross-bar. The pellets 88 are fed along a feed track 85 and a trackway 76 and the leading pellet comes to rest against a latch 80 in alignment with the plunger 68 and the can 87. It is arranged that carriage 2 is reciprocated by the cam 22, the required number of strokes to ensure that the trackway 76 is cleared of pellets. The air cylinder 32 is then operated to drive the plunger 68 through a final stroke independently of the action of the cam 22, the length of the stroke being such that the pellets are driven home into the can. Should the plunger 68 jam on a forward stroke, damage is prevented by unlatching of the balls 47. Since the cylinder 40 is arrested with the plunger, air is ejected from the cylinder by movement of the piston assembly 36 along the cylinder. The microswitch 59 is also operated under these conditions and a cut-out operates until the jam has been cleared. The cylinder remains positioned back towards the carriage 2 until compressed air is admitted into the cylinder via the pipe 64 &c. The spring- urged balls 47 are then re-engaged with the groove 51 of the rod 34.
