Title: Means for re-winding clocks and like mechanism by the effect of variations in the temperature of the air
IPC: G04B5/22
Filed: 1929-09-19
Abstract: 331,764. Reutter, J. L. Nov. 28, 1928, [Convention date]. Winding-apparatus; motors operated by variations in atmospheric pressure and temperature.-A heat-insulated container A (e.g. Dewar tube) contains a liquid B of high specific heat.. A container C therein has a volatile liquid l with its saturated vapour v (e.g. ammonia or carbonic acid) which vapour acts through tube D on the inside of a sealed bellows E. Acting on the outside of these bellows is the saturated vapour of a volatile liquid (e.g. ammonia &c. as above) in a box F having a tube G closed by an elastic window H. The pressure of vapour in D remains substantially constant, that in F is subjected to the change in atmosphere. Movements of bellows E due to atmospheric changes are used to wind up a clock or like mechanism through levers I, I'. In a modification, Fig. 2, the bellows are replaced by a U-tube having the liquid and its vapour in each limb separated by mercury A. Movement of the mercury due to changes in the vapour pressures cause movement of the device about a pivot X, this movement being used to wind up the clock. In a further modification, Fig. 3, the U-tube is curved and carried in the heat insulated space between casings B, B<1>, the inner case containing a liquid of high specific heat. One limb of the tube c contacts with the inner vessel B (constant pressure) and the other limb contacts with the outer casing B<1> (variable pressure). Here also movement of the mercury causes movement about a pivot X.

Abstract: 1,227,801. Steam generators. SIEMENSSCHUCKERTWERKE A.G. 14 June, 1968 [14 June, 1967], No. 28593/68. Heading F4A. In a forced-flow, once-through steam generator in which horizontal tubes, or tubes inclined by a small angle to the horizontal, are connected together by welding to form a pressure-proof wall surrounding a combustion chamber, there being a stiffening frame structure surrounding the wall and serving to brace it, the stiffening frame structure, or some of it, is used as a counterweight for at least partly relieving the weight loading the wall. Horizontal or nearly horizontal tubes 1 are welded together, either directly or through fins or, as shown, through interposed sheet-metal strips, to form a pressureproof wall surrounding a square combustion chamber. The wall is surrounded by an alloy of vertical bracing members 2 suspended at their tops from the generator framework. The wall is fixed to the members 2 at, say, two-thirds from the bottom and is slidably connected to the members at other places, e.g. at 8, to allow for relative expansion. The alloy of members 2 is surrounded by a stiffening frame structure comprising horizontal members 15 interconnected by vertical members 19. The weight loading of the wall is at least partially relieved by anumber of vertically spaced levers 10, each fulcrumed at 17 on a bracket 18 welded to a member 2 and pivotally connected at 11 to the wall and at 13 to a tie-bar 14 which is pivotally connected at 21 to a vertical member 19. The tie-bars 14 are evenly tensioned by turnbuckles.

Abstract: 364,024. Variable speed friction gearing ; speed governors. SALOMON, F. M. M. B., 130, Boulevard Brune, Paris. Sept. 25, 1930, No. 28764. Convention date, Sept. 25, 1929. [Class 80 (ii).] A shaft 6, Fig. la, is driven from a shaft 1 by balls 8 which are projected centrifugally outwards and roll round on bell-shaped driven and non-rotary members 5, 4, respectively. The speed of the shaft 6 is varied by moving the member 4 axially. The outward thrust of the gear balls 8 is reinforced by an inner ring of balls 18 supported as shown in Fig. 1 by cage elements 19, 20 and driven round by rollers 16 carried by arms 14 fast on the shaft 1. The effort to vary the speed is an axial force applied to the member 4, and to reduce this, the axial thrust of the gear balls 8 is balanced by the axial thrust produced by centrifugal balls 54, Fig. 2. The balls 54 reacting on a bell member 53 on the shaft 1 produce a thrust in a sleeve 2 connected to the bell member 4. The speedchanging effort is applied to a rod 51. An arrangement is described in which the speed varies automatically. The bell member 4 is mounted on a screw so that by yielding against a control spring it moves axially as required. The abutment of the control spring may be fixed, or movable by a governor. Such a governor may comprise a shaft 72, Fig. 4, geared to either of the shafts 1, 6, and carrying a bell member 74 of suitable internal contour. Loose governor balls 75 reacting centrifugally from the member 74 impart axial thrust to a sliding muff 76, which through a lever 77 pivoted at 78 and under control from a spring 79 effects the required displacement of the said abutment.

Apparatus for evaluating a frequency which is approximately known comprises gating means enabled for exactly one cycle of the frequency so that pulses of a predetermined frequency are passed to a counter counting down from a predetermined number, the count which, at the end of the cycle, represents the input frequency being displayed. In the form shown the input frequency after being shaped to square wave form is applied to a first gate 9 enabled by a bi-stable device 8 under the control of a display timer 1. The start of a negative output pulse from gate 9 sets a further bi-stable device 11 and the start of the next negative pulse resets it so that a gate 12 is open for precisely one cycle to pass pulses from an oscillator 13, their frequency being determined by the formula K - where T is the range of the periods of the T frequencies for which the apparatus is to be used, e.g. 1/ 45 - 1/ 55  and K is the difference between the frequencies multiplied by a scale factor dependent on the number of decades in the counter, e.g. (55 - 45) x 10. The counters to which the reference pulses are passed count down from a number dependent on the frequency of the reference pulses and the approximate value of the unknown frequency.
