Title: Improvements in gear sets
IPC: F16H1/22
Filed: 1949-08-30
Abstract: 660,879. Toothed gearing. THORNTON, A. A. (Falk Corporation). Aug. 30, 1949, No. 22491/49. Class 80 (i) [Also in Group XXXIII] A gear set for driving two coaxial shafts 14, 15 in opposite directions (applicable to the propellers of helicopters, air planes and the like) is designed so that the torque transmitted is equally divided between a plurality of layshafts. The gear set, Fig. 1, is contained in a housing comprising separable sections 10-13. The hollow shaft 14 carries an internal gear 20 engaged by a group of three helical pinions 24 and a further group of three pinions 24'. The pinions are mounted on shafts 25, 25<SP>1</SP> respectively, carrying helical gears 29 or 29<SP>1</SP> driven by pinions 30, 31'. The six shafts 25, 25<SP>1</SP> are arranged symmetrically around the axis of shaft 14 and are journalled in a ring 19 and web 28 of the housing. The pinions 30, 30' are carried by sleeves 31, 31<SP>1</SP> loosely coupled by helical teeth 34, 34' to rings 32, 32<SP>1</SP> secured to a sleeve 33 loose on the shaft 15. The sleeve 33 is coupled by straight spur teeth 39 to a gear 35 journalled in webs 28, 37 and driven through gears 40, 41 from a drive shaft 42. A similar system of six shafts 45, 45', driven through helical gears 49, 49' by floating pinions 50, 50<SP>1</SP>, carry pinions 44, 44' engaging an external gear 23 on the shaft 15. The helices of the two groups of gears 29, 29' are of opposite hand, as are, similarly, the helices of the groups 49, 49'. In a modification, Fig. 2 (not shown), an arrangement of gearing is described in which the input and output shafts are coaxial, and the six pinions driving the inner output shaft are mounted on hollow shafts each surrounding one of the six shafts carrying the pinions driving the outer output shaft. In the modification shown in Fig. 3 the two driven shafts 84, 85 carry respectively an internal gear 88 and an external gear 90. The former is driven by three pinions 91 carried by shafts 92 which are driven through helical gears 94 by a pinion 95; the gear 90 is driven by three pinions 91' carried by shafts 92<SP>1</SP> which are driven by a pinion 95'. Both pinions 95, 95<SP>1</SP> are carried by a drive shaft 96 driven through a flexible coupling 97 so as to be free to float axially and radially. The pinions 95, 95<SP>1</SP> have helices of opposite hand, the helix angles being so related that the torque carried by the shaft 96 is equally divided between the two pinions. Fig. 4 (not shown) discloses an arrangement of gearing similar to that of Fig. 3 but using double helical gears and pinions throughout. In this modification the two driving pinions (comparable with 95, 95<SP>1</SP> in Fig. 3) are separately driven by two tubular connectors flexibly coupled to a driving member so that each driving pinion may float radially and axially.

Abstract: 785,544. Multiplex radio signalling. ELECTRIC & MUSICAL INDUSTRIES, Ltd. July 29, 1955 [Aug. 4, 1954], No. 22567/54. Class 40 (5). In a system for transmitting television and the accompanying sound signals at U.H.F., the two carriers, which are of closely related frequency, are amplitude modulated at low level, combined, and then amplified together by a klystron amplifier. The two carriers derived at 3 and 6 from crystal oscillators are modulated at 2 and 5 by the video and audio signals respectively. The modulated outputs are fed to a combining filler 7 and thence to the input cavity 9 of a klystron amplifier which is coupled to the aerial by cavity 11. To reduce cross-talk, overall negative feed-back of signal components up to 20 kc/s. is applied via frequency selective circuits 14, 15; or a part of the video signal may be fed in anti-phase to the audio modulator and vice versa.

Abstract: 1442549 Controlling vehicles KOEHRING CO 21 May 1974 [11 June 1973] 22635/74 Heading B7H [Also in Division F2] A hydrostatic transmission pump displacement and engine throttle control linkage for a load handling vehicle comprises a pedal 42 which, when pivoted about an axis 41 in one direction or the other, acts through an arm 90, a cable 93 and linkage 100 on pump displacement adjusting levers 57A, 58A to increase pump displacement in the forward or reverse direction, in addition the pedal acts through links 130, 131 and arms 150, 151 to rotate sleeves 133, 134 in opposite directions on a shaft 102 whereupon a projection 146 or 147 on one of the sleeves engages a projection 144 on the shaft 102 to rotate the latter which acts through a plate 108 and cable 124 on a throttle control lever 51 to increase fuel supply to the engine. Engine fuel supply may be increased without increasing pump displacement by depression of another pedal 40 which acts through a link 116 directly on the plate 108. A spring 122 biases the throttle control linkage to an engine idle position and also acts through the shaft 102 to bias the pedal 42 towards its zero displacement position as shown. The pump displacement control cable 93 is connected to a lever 164 fast with a shaft 160 carrying arms 165, 169 respectively connected through a link 167 to the pump displacement adjusting lever 57A and through a rod 170, bell crank 172 and link 173 with the pump displacement adjusting lever 58A. The pump displacement adjusting levers 57A, 58A are biased towards their zero displacement positions by springs 176, 177 acting on the rod 170. The levers 57A, 58A control pumps 57, 58 driven by a common engine 20 and respectively supplying pressure liquid to front wheel motors (72) and rear wheel motors (74), Fig. 11 (not shown). The pumps and wheel motors may be variable displacement swashplate units. A switch 200 actuated by the arm 90 of the pedal 42 prevents the engine being started when the pedal 42 is in a position other than its zero pump displacement position. The engine 20 may drive additional pumps which supply pressure liquid to hydraulic rams which operate the load handling equipment and vehicle steering.
