Title: Improvements in the construction of cabinets and framework of wireless receiving sets
IPC: H04B1/08
Filed: 1926-01-20
Abstract: 268,475. Walton, G. W., and General Radio Co., Ltd. Jan. 20, 1926. Receiving sets, construction of.-Wireless receiving-sets of the enclosed type have the panel and baseboard integrally formed in one piece which can be withdrawn from the cabinet bv a pivotal, sliding, or combined movement. As shown in Fig. 1, the panel 1 and baseboard 2 are formed integrally of metal or other suitable material, and are strengthened by flanges 3 welded at the mitre joint 7. The set is rendered accessible by swinging it about pivots 4 which are secured to the cabinet walls and enter recesses in the flanges 3. Alternatively, the pivots pins may be attached to links pivoted to the cabinet. In another form, the webs 3 have tongues which slide in horizontal grooves in the cabinet walls, the set being withdrawn like a drawer. Fig. 4 shows in plan another alternative, in which the baseboard 2 is semicircular, and the set can be rotated around a central vertical pivot 8 for inspection &c. The cabinet 9 may in this case be in the form of a half cylinder In another form a rectangular base is suspended by vertical pairs of links at front and rear, and the set is exposed by pulling forward the panel and baseboard, the links causing both to rise, with a parallel motion. Or the front pair of links may be omitted, and the set tilted as it is withdrawn. In a further modification shown in Fig. 5, the set is suspended by short side links near the top of the panel.

Title: Improvements in or relating to pitch-changing mechanism for airscrews
IPC: B64C11/44
Filed: 1940-01-31
Abstract: 538,386. Controllable pitch airscrews. CURTISS-WRIGHT CORPORATION. Jan. 31, 1940, No. 1940. Convention date, March 15, 1939. [Class 114] [Also in Groups XXXV and XXXVII] In controllable pitch airscrews having electrically actuated pitch changing means energized in response to engine speed changes from a pre-set speed means are provided for adjusting the average rate of pitch change in proportion to the degree of instantaneous speed difference of the engine from the pre-set speed. The governor 43 arranged in a housing 19 is driven from the engine through the connection 20 and its preset speed is adjusted by variation of the spring loading from the lever 51. The governor arms control the position of the valve stem 49 which in turn controls oil pressure in the cylinder 68 in which works a spring-loaded piston 70. The stem 74, Fig. 3, of this piston is embraced by a housing 78 which provides a spring-cushion for a contact 80 which follows the movements of the governor between contacts 78 which are reciprocated in proportion to the engine speeds, being mounted on a plunger 81 which is operated by a cam 92 mounted on an engine-driven shaft 96. The device of the contact 80 with the contacts 38, 39, which determines the time during which the pitch-controlling electric motor is energized, is thus proportional to the variation of the governor from pre-set speed. Arrangements are made to effect cessation in operation of the governor control means on a drop of the fluid pressure in the governor control system below a pre-determined medium.

Title: Improvements relating to heat exchange apparatus for the cooling of fluids
IPC: F28D7/02
Filed: 1949-01-25
Abstract: <PICT:0667281/III/1> <PICT:0667281/III/2> A medium to be cooled, e.g. a mixture of gases such as coke oven gas having condensible components such as benzene, flows in a helical path around a core 3 in a tubular casing 1 and over cooling elements, e.g. tubes 8 through which flows a cooling medium.  Moreover, as seen in section, Fig. 2, the axes of the elements lie in concentric circles, the spacing between axes of adjacent elements of a circular series being the same for the whole nest, i.e. at least three and preferably four times the diameter of an element 8, and the radial widths of the annular spaces between the successive circular series, i.e. the distance between circles less the diameter of one element in each case, increase from the core outwards in substantial proportion to the mean radii of the successive annular spaces.  It will be seen that the radii of the circles increase outwardly approximately in geometric progression. As an approximation, the widths of the annular spaces may be proportional to the radii of the circular series.  The arrangement is said to permit the linear velocity of the medium to be cooled to be the same over the width of the helical path.  A helical wall 2 forms the path, up from an inlet 4 to an outlet 5, for gases to be cooled. The cooling medium flows through the tubes 8 from inlets 6 to outlet 9 and condensate from the cooled gases flows down the helical wall to an outlet 11.  A benzene column may have 1,400-2,600 tubes 8, each of 0.75 cm. diameter, and a helical path of 6-17 convolution.

Abstract: 667,095. Toothed gearing. JONES & CO. (ENGINEERS), Ltd., W. Jan. 3, 1950 [Jan. 31, 1949], No. 2648/49. Class 80 (i). A device for producing non - uniform rotation of the cams operating switches in an electric circuit, and the like, consists of a spur gear 1 having teeth on its whole periphery freely mounted on a shaft 2. Concentric with and longitudinally aligned with the spur gear 1 is an internally toothed wheel 3, also freely mounted on the shaft 2. In the annular gap between the toothed wheels 1, 3 and engaging with both is a pinion 4, from which one or more of the teeth have been removed as at 7, leaving at least two teeth between any two removed teeth. The internally toothed wheel 3 has teeth on a short arc 8 of its periphery (or several such arcs) so that these groups of teeth correspond to those remaining on the pinion. The blank part 9 of the inner surface of the internally toothed wheel 3 is of such a diameter that it will just touch the corners of two pinion teeth adjacent to a cut away tooth 7 on the pinion 4 thus preventing the rotation of the pinion on its own axis save when engaged with the teeth cut in the internally toothed wheel. A constant relative angular velocity between the spur gear 1 and the internally toothed wheel 3 causes the axis of the pinion 4 to move with an interrupted motion about the shaft 2, sometimes with the angular velocity of the spur gear and at other times, when the teeth of the pinion engage with the teeth 8, with a velocity dependent upon the relative velocity between the spur gear 1 and the wheel 3. This motion of the axis of the pinion 4 can be imparted to a cam 5 mounted concentric with the device by means of a pin 6 on which the pinion is freely mounted. The reaction member of the device may be either the internally toothed wheel 3 or the spur gear 1. The non-uniform rotation of the pin 6 can also be used to drive the internally toothed wheel or the spur wheel of another similar mechanism mounted coaxially with the first on the shaft 2. In modifications of the device, either or both of the geared wheels 1 and 3 may have teeth on parts only of their peripheries.
