Abstract: 632,028. Epicyclic gearing ; operating variablespeed gears. HUMBER, Ltd., and KAMPER, A. M. Jan. 14, 1948, No. 1185. [Classes 80 (i) and 80 (ii)] An epicyclic gear train adapted for connecting and disconnecting a drive is shown applied to the operation of a gear shifting mechanism for variable-speed gearing. An electric motor 3 having forward and reverse windings 35, 36, drives a planet carrier 6 supporting stepped planets 9, 10 engaging respectively a sun wheel 14 secured to the gear change lever 34, and a reaction sun 25 adapted to be electro-magnetically clutched to the casing 2. The gear change lever 34 carries electric contacts 33 engaging three concentric contact strips 30, 31, 32, strips 30, 31 being connected respectively in series with the forward and reverse windings 35, 36 of motor 3, and both with the coil 38 of a relay controlling the electromagnet. When one of two push-buttons 50, 51 controlling the supply of power to contact strips 30, 31 is actuated, the motor 3 is operated and the reaction brake applied to move lever 34 in one direction or the other until the corresponding contact 33 moves off the strip and the drive is stopped with lever 34 in the position appropriate to one gear ratio. Actuation of the other push button moves the arm in the reverse direction to a position appropriate to a second gear ratio, the positions of the contact strips 30, 31 being arranged so that when one contact 33 runs off one strip the other contact 33 is still on the other strip. The third concentric contact strip 32 is divided and has its portions in series with the forward and reverse windings of motor 3 respectively and both in series with relay coil 38, so that on supplying power to either portion by a push button 52, the lever is moved towards its central position corresponding to neutral position of the gear. Relay 38 may also be used to control a main clutch, not shown.

Classes 75(ii) and 75(iv) In a lighting fitting having at least one reflector, for use in conjunction with at least one light source, the shape of the reflecting surface being generated geometrically by the displacement of a co-planar continuous line which includes at least one parabolic arc and at least one elliptical arc having a common focus which coincides substantially with a point on said light source or on one of said light sources, the concave sides of these curves facing the light source or sources, the distance between the foci of the elliptical arc is longer than the width of said light source or sources measured in a direction parallel to the major axis of the ellipse and said common focus is farther from the vertex of the parabola than the other focus of said ellipse. The light source may be a tubular fluorescent lamp 1, Fig. 1, the length of which is parallel to the generatrices of the curved reflecting surface having a section shown by the continuous co-planar line 2, 3, 4, 5. The latter comprises a first elliptical arc 2 to 3, a second elliptical arc 3 to 4, and a parabolic arc 4 to 5, the parabola having its apex at the point 4 and a horizontal axis I-I coinciding with the major axes of the ellipses. The end 2 of the first elliptical arc is located on the axis I-I; and the focus 6 of the parabola substantially coincides with the centre of the section of the light source 1 as well as with one of the foci of each of the ellipses, the other foci 7, 8 of the latter being located between the focus 6 and the apex 4 of the parabola. The distance between the foci 6, 7 is slightly greater than the width of the envelope of the source 1 measured along the axis I-I in order to minimize the amount of rays reflected by the portion 2 to 3 impinging on this envelope. Light rays such as 9 are reflected directly by the parabolic portion 4, 5 as horizontal rays 10, whilst rays 11, 15 emitted towards and reflected by the elliptical portions 2, 3 and 3, 4, respectively, are subsequently reflected by the parabolic portion 4, 5 as rays 13, 14.

Title: Internal combustion engines and control mechanism for clutches therein
IPC: F16D25/12
Filed: 1957-01-14
Abstract: 843,551. Gearing for stopping and starting machinery. FICHTEL & SACHS A.G. Jan. 14, 1957 [Feb. 17, 1956], No. 1334/57. Class 80 (2). An internal combustion engine 11 drives the road wheels of a vehicle through a clutch 12 the engagement of which following a ratio shift is cushioned and controlled in dependence on the depression of the inlet manifold 27 and the speed of rotation of the engine. The clutch is disengaged when a lever 13 is turned on connecting a servomotor 15 through a valve 17 to the inlet manifold 27. The valve 17 comprises a solenoid 34, energized when the gear shift lever is operated to withdraw a valve closure member 19 and connect pipes 28, 16 leading from the inlet manifold 27 to the servomotor 15. When the solenoid 34 is de-energized after completion of the shift to re-engage the clutch 12, the pipe 16 leading to the servomotor 15 is connected through a hole 36 to a space 23. The pressure in the space 23 is thus reduced, so that atmospheric pressure acting through a hole 40 and space 22 can open a disc valve 18 against the bias of an adjustable spring 37. Accordingly the clutch 12 partially re-engages. The difference between atmospheric pressure and the pressure in the space 23 is now such that the spring 37 has once more closed the valve 18. Opening the throttle of the internal combustion engine 11 to increase engine speed reduces the pressure in the inlet manifold 27, i.e. increases the pressure within the manifold, and this increasing pressure acts through a pipe 29 upon a diaphragm 21 which accordingly moves to the right of Fig. 2. Either the engine lubricating system (not shown), or the engine cooling water pump 31, is connected by a pipe 30 to a chamber 25 containing a diaphragm 26. Increasing engine speed increases the water (or oil) pressure within the space 25, which acts upon the diaphragm 26 and moves it to the right of Fig. 2 against the bias of a spring 43 to act through a spring 42 and assist the rightward movement of the diaphragm 21 caused by increasing inlet manifold pressure. A stem 41 is thus brought into engagement with the valve 18, which is again opened, to allow the clutch 12 to complete its engagement. In a modification, Fig. 3 (not shown), the clutch 12 is electromagnetically engaged and the stem 41 acts successively upon contacts shunting out series resistors in the clutch control circuit. Specification 818,058 is referred to.
