Title: Rear view mirror assembly
IPC: B60R1/08
Filed: 1955-11-28
Abstract: 787,779. Hinges and Divots. LIBBEYOWENS-FORD GLASS CO. Nov. 28, 1955 [Dec. 7, 1954], No. 33971/55. Class 65(2) [Also in Group XXXII] A rear-view mirror for automobiles comprises a support plate 23 carried by a truncated ball 32 secured to the automobile, the plate having slots 25 to receive bent tabs 24 on a mounting plate 19 which carries a casing 11 for a mirror element 10 of wedge section. The tabs 24 are maintained in position in the slots 25 by means of leaf springs 27 which extend through slots 28 formed in the tabs and are held at the bottom in slots 29 in a flange 21 of the mounting plate 19. An actuator arm 41 is pivoted to the plate 19 at 42 and is provided with a bar 43 formed with a slot 44 which receives a cam plate 45 carried from the support plate 23. The lower portion of the arm 41 passes through slots 49 in the flange 21 and in the bottom wall 14 of the casing 11 and has a knob 50 which can be moved in an arcuate path. This movement causes the cam plate 45 to ride in the slot 44, so that the mounting plate pivots on the support plate 23 and the mirror and its casing are moved to one of three positions determined by the engagement of a protuberance 51 on the actuator arm 41 in one of three depressions x, y and z provided in the plate 19. The mirror 10 as shown has a body a of glass or other transparent material and has front and rear reflection surfaces b, c respectively. The surface b may be semitransparent and have a reflectivity much less than that of the surface c. In a modification, torsion springs are used to hold the tabs 24 in place and the depresions x, y, z are adapted to be engaged by a spring-pressed ball instead of the protuberance 51. Specification 757,974 is referred to.

A screwed rod 19 is pivoted at 20 to the support 17 and is adjusted by a nut 22 which bears on ball and cup washers 24 and is pressed downwards by a spring ring 25. The kerfing bit is shown in dotted lines in two positions of adjustment, the bit being arranged in sets of three cutters which are staggered so that each successive cutter deepens the groove, or are staggered to produce a widening of the groove by successive cutters.

Abstract: 1395986 Generating combustion products under pressure; gas turbine plant ENGELHARD MINERALS & CHEMICAL CORP 20 July 1972 [21 July 1971] 34071/72 Addition to 1395422 Headings F1G and F1L In a modification of the method of adiabatically oxidizing a carbonaceous fuel described in Specification 22494/72 the fuel/air mixture is passed through a zone containing an oxidation catalyst at a temperature of between about 1500 and 3000‹F where partial oxidation occurs and then through a non-catalytic zone where further oxidation occurs at a temperature of between about 1500 and 3000‹F. The volume ratio of free oxygen to fuel in the mixture is at least 1.1, e.g. at least 2, times the stoichiometric amount required for complete combustion. The amount of catalyst is less than half, e.g. 0.02 or 0.01, the amount needed to completely oxidize the fuel to carbon dioxide and water, the volume of the catalytic zone being less than the non-catalytic zone. The fuels, catalysts and plant operation are in other respects generally as specified in the parent Specification. In one application to a gas turbine plant having a compressor 12 and turbine 14 the oxidation reaction is carried out in a chamber 30 having a first catalytic zone 31, a non-catalytic combustion zone 32 and a second catalytic zone 33 of greater volume than zone 31. In a modification Fig.2 (not shown) zone 33 is disposed between turbine 14 and a separate power turbine 51 so as to effect inter-stage re-heating. Cooling air may be added between chamber 30 and turbine 14 and the air and fuel may be pre-heated prior to entering chamber 30.

Abstract: 504,650. Vehicle bodies. WEAKLEY, F. J. Dec. 9, J937, No. 34146. Addition to 396,977. [Class 108 (i)] In order to connect together the metal members of vehicle body frames described in the parent Specification, or to connect the members with other members, or to facilitate the connection of wooden parts such as panelling &c. to the frame members, a plate 14 secured to the part to be connected is interposed between the flanges 11 of the channels 10 comprising the frame member. As shown, the plate 14 replaces part of the web 12 of the frame member and extends laterally for the connection thereto by welding of a channel member 16 which is reinforced by a web 17. A second channel member 21 may be secured as shown so that the channels 16, 21 form a frame member as described in the parent Specification. In another construction the web 12 extends throughout the frame-member the flanges of which are deformed to accommodate the plate 14 to the laterally-projecting parts of which wooden rails are bolted or otherwise secured. In a modification of the latter construction instead of the rails further frame members are secured to the plate 14. The plate, instead of extending across the frame member may be nipped between the flanges of the channels. The outer-faces of the channels may be formed with recesses or grooves into which a wooden strip or packing box of fibre &c. can be inserted to receive wood screws for securing panels or wooden rails thereto.

Abstract: 1395945 Fuel elements ALKEM GmbH 21 July 1972 [24 July 1971] 34373/72 Heading G6C A Pu-containing fuel rod is made by first coating the inner wall of a cam with a layer of a Pu-containing non-metallic matrix and subsequently introducing a U-containing fuel filling into the can which is then sealed. Both the Pu and U are preferably in oxide form. For example, a suspension of Pu-containing particles in a lacquer, e.g. a nitrocellulose or a cellulose acetate dope, capable of being decomposed to carbon by heating is passed through the can. The inner wall of the can then carries a film of the suspension which after drying in an inert atmosphere is heated at approximately 250 C. until coked. In this manner, the Pu-containing particles are embedded in a carbon matrix. The ratio of the volume of carbon to that of Pu compound in the coating lies between 1 : 5 and 1 : 20. The thickness of the coating should be between 10 and 100 microns, while the Pucontaining particles should have a diameter less than 10 Á and preferably less than 1 Á. The U-containing fuel filling may be in the form of either pellets or granules.

Abstract: 480,983. Actuation of switches. FAIREY AVIATION CO., Ltd., and FORSYTH, A. G. Dec. 15, 1936, No. 34443. [Class 38 (v)] Switch mechanism for controlling the extent of travel of an electric motor comprises a tubular spindle d carrying a knob e having a pin f which engages a slot in the spindle and is biassed to the left by a spring g. The knob e has two pins p engageable in a series of holes in a gear wheel m loosely mounted on spindle d and arranged to be driven by a reversible motor (not shown) acting through a flexible shaft fixed to a sleeve y carrying a pinion 11 engaging gear m. The spindle d carries cams r, s co-operating with the operating members of switches t, u the closure of which causes the motor to be driven in opposite directions according to which direction the cams are turned from the central position in which both switches are " off." In operation, the knob e is pulled to the right to disengage pins p and the knob is turned in the appropriate direction the desired amount as shown by an index k against a dial n carried by the gear m, and then released to re-engage pins p. This closes the appropriate switch t or u and the motor rotates, driving the parts y, 11, m, e and d until the cams are back at the central position and the motor circuit is opened. The mechanism is applicable to the control of variable-pitch aircraft propellers.
