In the form shown in Fig. 1, the heater comprises a baseplate 1 attached by spacing bolts 3 to an annular cover-plate 2 having a central boss 4 carrying an electric motor 6 and a fan 7. The fan blades are at an angle of approximately 45‹ to the fan shaft and serve to draw in air through a filter 10, arranged between the annular plate and the boss 4, and blow it out radially over a radiator consisting of wire wound tubing 8 supplied with hot water or other heating medium. In a modification the central boss 4 is omitted and the motor is carried by the baseplate which is so shaped as to deflect radially outwards the air drawn in by the fan which is disposed approximately in the plane of the annular plate. In a further modification the motor is disposed outside the space between the plates 1, 2 and drives a blower of the centrifugal type. In the modification shown in Fig. 5 the plate 1 is formed with a sleeve 17 which projects through the roof of the vehicle and is formed with bearings for a shaft 20 by means of which the fan is driven by a wind motor 21 disposed on the roof.
Patent GB-645855-A (GB)
Title: Manufacture of pyrophorous- and hydrogen-producing compositions
IPC: C06C15/00
Filed: 1948-01-28
Abstract: Pyrophoric compositions are prepared by mixing in the ratio of their atomic weights dried and powdered sodium hydroxide or potassium hydroxide with finely divided aluminium.  One third the volume of a container is filled with sodium hydroxide powder and the powdered aluminium is then added and the container shaken to mix the powders. The mixture is said to burn when exposed to air in which moisture is present.  When potassium hydroxide is used, it is first heated and melted with about 5 per cent of colophony before mixing with the aluminium powder in the proportion potassium hydroxide with colophony: aluminium 68.5:31.5 parts by weight.  To change the powder mixtures to a granular form the pyrophoric composition is drenched in a solution of colophony in petrol, the petrol is then evaporated and the resultant mass crumbled into granules.  The powder mixture may also be formed into a paste by adding a liquid hydrocarbon to the mixture. Instead of a liquid hydrocarbon boiled linseed oil, castor oil or rape-seed oil may be used.  A porous, fragile body may be made by adding to the granular form of the composition condensed waterglass.

Patent GB-310561-A (GB)
Title: Improvements in typewriter tabulating mechanism
IPC: B41J21/14
Filed: 1928-01-28
Abstract: 310,561. Jardine, Ltd., J., and Ball, H. J. Jan. 28, 1928. Tabulating - mechanism; tabulating - stops; carriage-releasing arrangements.-A typewriter is provided with a tabulating-stop bar which is rotatable about end journals so that it can be inverted and simultaneously lowered for the purpose of setting, by the ordinary tabulating- dogs, one or more of a series of adjustable stops mounted thereon. The stop-bar A, Fig. 1, is eccentrically journaled within twin bearings B<1> on brackets B whereby when it is turned through 180‹ into the reversed position, as shown, it assumes a lower position than normally and is brought nearer to the upper ends of the dogs D. A short longitudinal movement is imparted to the stop-bar simultaneously with its rotary movement, to bring the stops E into register with the dogs D. This movement is obtained by providing the end remote from the knob M with a pin which bears against a cam-face on the adjacent bearing B', the journal at the other end of the stop bar being splined within a sleeve N which is riveted to the handle shaft. A helical spring is interposed between the end of the handle shaft and the journal of the bar A, and an indiarubber collar A<2> mounted on the journal between the bearing plate and the bar acts as a buffer when the stops E strike the tabulating-dogs D. The stop-bar A is formed with a longitudinal groove A<3> and the stops E, Fig. 5, with portions E' offset from the plane of the main portion and terminating in ends E<2> which engage in the groove A<3>. The offset portions of the stops serve as retaining-springs when the stops are projected. The selection and projection of the stops is effected, after reversing the stop bar, by traversing the carriage in the usual way and actuating the ordinary tabulating keys to cause the dogs D to push up the stops E, the stop bar afterwards being restored to its normal position. After tabulating, the stop bar is again reversed and the stops are restored to their inoperative position by traversing above them a slipper F slidably mounted upon a longitudinal bar G disposed above and parallel to the stop-bar. Offset rear extensions of the bearing-brackets B are connected to the bar G and are adjustably secured to the end frames C of the paper carriage by screws inserted within longitudinal slots. A slot is provided in the bearing sleeve N to expose signs indicating the relative position of the stop bar. The bell crank levers Q, Fig. 8, connecting the lower ends of the tabulating-dogs to the respective tabulating-keys are mounted upon a common shaft R and are spaced apart by providing the universal bar S with a corresponding number of slots into which they fit, the bar S being pivoted upon the shaft R by bending its edge S<1> to embrace part of the shaft. The transverse bar T pivoted at its ends to the bar S carries a central extension T<2> actuating the escapement in known manner.

Patent GB-524328-A (GB)
Title: Improvements in or relating to agitators for suction cleaners
IPC: A47L9/04
Filed: 1939-01-27
Abstract: 524,328. Vacuum cleaner brushes. HOOVER, Ltd. Jan. 27, 1939, Nos. 2855, 2856 and 2859. Convention dates, April 23, 1938, Dec. 17, 1938 and Dec. 29, 1938. [Class 8 (i)] The rotary agitator 1, Fig. 1, of a vacuum cleaner has rigid ribs 4 and brushes 5 adapted to slide in grooves to a position determined by a limiting surface, the brush being clamped in position during normal rotation, and released at starting or stopping. Fig. 3 shows the clamping means as comprising a, rocker 17 which holds a plate 12 linked to rods 8 hinged to the brushes in the position shown when at rest. The start of rotation releases the rocker and allows the brush to move outward till it contacts a limiting plate 21 ; when normal speed is reached, a claw 18 on the rocker is caused to engage the plate 12 and move the plate counter clockwise, retracting the brush slightly. In one modification, two rockers 17 are provided, one pivoted on the other, so that when one rocker is released from the agitator it frees the second from a catch and allows it on the attainment of speed to engage and clamp the agitator. In a further modification, the rods 8 carry pinions guided on racks and clamped by teeth on one arm of a rocker at rest, released during speeding- up, and clamped by the other arm at full speed. In another modification the brush is carried by a pivoted arm on the agitator and pressed outwards by a spring, a stop limiting the motion. A toothed rocker is counterweighted and spring pressed, and on attainment of speed grips the brush. Fig. 12 shows the brush carrying a rack 46 engaged by a weighted lever 47 ; the start of motion draws the lever by its inertia against the stop 50, disengaging its teeth from the rack. The brush moves into contact with a limiting shoe 21, and at normal speed the spring draws the lever back to engage the rack and move the brush slightly back.

Abstract: 976, 297. Top roller loading arms. SPINNEREIMASCHINENBAU KARL-MARX-STADT VEB. Jan. 26, 1962, No. 2989/62. Heading D1D. A top roller carrying and loading arm 1 is clocked in its operative position by a pair of articulated levers 5<SP>11</SP> and 6<SP>11</SP>, one of which is pivoted on the arm at 8 while the other is pivoted on a stationary pivot 7, the lever 5<SP>11</SP> also co-operating with or, as is shown, forming part of an operating lever 4<SP>11</SP> able to be rotated to shift the arm 1 into or out of its operative position,at least one further lever 25<SP>11</SP> pivoted about a stationary pivot 26 being provided to lock the arm in its inoperative position (Fig. 6). As shown the stationary pivots 7 and 26 are on a flange 3 clamped to the supporting bar 2 about which the arm 1 is rotatable, the flange also providing lateral location for the arm. Elongated slots in levers 6<SP>11</SP> and 25<SP>11</SP> serve to limit the movement of the levers in their extreme positions. In further forms the operating lever 4<SP>11</SP> is separate from lever 5<SP>11</SP> but is operatively connected thereto either by an arrangement of stops and slots (see Figs. 1, 3, 11, 15 not shown) or by a further lever (see Fig. 13 not shown). The single retaining lever 25<SP>11</SP> may be replaced by a pair of articulated levers (see Fig. 1 not shown) in which case they are operatively connected to lever 4<SP>11</SP> by means of stops and extensions. In preferred forms the lever 4<SP>11</SP> may be lifted a certain distance from the arm 1 when it is in its operative position without unlocking levers 5<SP>11</SP> and 6<SP>11</SP> so that adjustments at the upper surface of the arm may be made. This is achieved by providing play in the linkage between levers 4<SP>11</SP> and 5<SP>11</SP> (see Figs. 1, 3, 11, 15 not shown) or by providing a manually detachable catch between the two (see Figs. 13 not shown). In forms in which levers 4 and 5 are separate lever 4<SP>11</SP> may rotate about the pivot 8 or may be pivoted on the lever 5<SP>11</SP>. A variety of springs and stops may also be provided to bias the locking levers into and hold them in their locking positions.
