Title: Improvements in and relating to motion transmitting mechanisms adapted, for instance, for the actuation of the control surfaces of aeroplanes
IPC: B64C13/24
Filed: 1935-05-03
Abstract: 460,841. Linkwork. ELLIS, D. L. May 3, 1935, No. 13282. [Class 80 (iii)] [Also in Group XXXIII] Motion is transmitted to a controlled rod 35, Fig. 5, by two paths, which, in the neutral or zero position oppose each other, thereby producing an irreversible dead centre. In Fig. 5, the controlled rod 35, extending to a servo control-surface on an aircraft, is pivoted to the mid-point of a floating lever 33, the lower end of which is pivoted to the pilot's control rod 32, whilst its upper end has an approximately simple harmonic movement imparted to it from the control rod 32, by means of a connecting-rod 36 and a crank 38, secured to a sprocket 40, receiving a chain 41, secured at its ends to the control rod 32 and passing round guide-sprockets 45. Instead of controlling the rod 32, the pilot may turn the sprocket 40 by a cable (shown dotted). The motion of the rod 35 is thus a combination of linear and simple harmonic, as shown in Fig. 7. The mechanism shown in Fig. 8 produces a similar movement of a rod 59, pivoted to the mid-point of a floating lever 52, the upper end of which is pivoted to the pin 51 of a crank 50, secured to a shaft 48, which is turned by a control cable 46. The lower end of the floating lever 52 receives an approximate simple harmonic motion at an increased ratio of preferably 3 to 1, by means of a connecting - rod 5 and crank 54, secured to a sprocket 56, connected by an endless chain 57, with a larger sprocket 49, secured to the shaft 48. In a modification, the upper end of the floating lever receives its linear movement by a direct linkage connection with the chain 57 itself, and universal joints are used at each end of the connecting-rod 5. The Provisional Specification describes also further modifications, in one of which the controlled rod is pivoted to one arm of a bell-crank lever, carried by a crank-pin secured to a sprocket, which is connected by a chain with an equal sprocket, also carrying a crank connected to the other arm of the bell-crank lever. Motion may be imparted to the mechanism by a cable or acting on one of the cranks. A further modification uses all pin-joints, the controlled rod being pivoted on one arm of a bell-crank lever, which is carried on one arm of a second bellcrank lever, mounted on a fixed pivot. A control rod is connected by rods with the remaining arms of both bell-crank levers. The mechanisms are applicable to non-servo controls.

Title: Improvements in or relating to protective systems for alternating current generators
IPC: H02H7/06
Filed: 1959-04-20
Abstract: 863,770. Protective cut-out arrangements. WESTINGHOUSE ELECTRIC CORPORATION. April 20, 1959 [April 24, 1958], No. 13389/59. Class 38 (5). [Also in Group XXXV] A protective system for a generator operating either alone or in parallel with others comprises means whereby, should the output voltage become unstable through faulty operation of the voltage regulator or, in a parallel operating system, through failure to synchronize properly, the generator is disconnected by operation of its circuit-breaker and-if desired-its field winding de-energized. An alternating current generator 1 is connected in parallel with another alternating current generator 2 to busbars 3 by means of circuit-breakers 4, 5, respectively. Faulty operation of a voltage regulator 11 associated with, say, the generator 1 causes instability resulting in oscillations in the output voltage of the generator. The oscillations will be reflected in the output voltage of a rectifier bridge 15 supplied by way of a transformer 12. The output of the rectifier bridge 15 is connected to a filter circuit 21-23 which filter circuit gives an output when the modulation of the generator output voltage by the oscillations therein is within a predetermined range of frequencies and is in excess of a predetermined magnitude. The output of the filter is amplified by a transistor amplifier 26 and is arranged to charge a capacitor 33 such that when the charge on the capacitor 33 exceeds the break-down voltage of a Zener diode 34 energization of the trip coil 7 of the circuit-breaker 4 causes the generator 1 to be disconnected from the system. If desired, the field winding 8 may be deenergized at the same time. Operation of the system upon the occurrence of transitory conditions is prevented by the delay introduced by charging of the capacitor 33 whilst selection of the faulty generator is provided by means of the transformers 16 and saturable current transformers 19 similarly to the manner set out in Specification 858,646. The system may also be applied to protection of a single machine. Specification 745,964 also is referred to.

A power operated circular saw bench for attachment to a tractor comprises a frame having securing means for connecting it to the back of a tractor, a saw-driving shaft mounted in bearings fixed against movement on said frame, a cross-cutting table which may be moved towards or away from the saw-driving shaft and a ripping table which is fixed to the frame so as to extend on both sides of said shaft. The ripping table, and a circular saw when associated therewith, are preferably arranged to one side of the securing means so that they project beyond the side of the trailer. In one form, Fig. 2, the frame comprises a tubular cross-member 10, attached by cantilever arms to a pivot at the back of the tractor, which has a platform framework 15 attached to it carrying a swinging cross-cutting table 16 as described in Specification 608,904. A saw shaft, carried in bearings spaced apart by a cylindrical member 21 and driven by a belt drive from the tractor, carries a circular saw 22 in either of two positions (the saw being shown in both positions). A ripping table, having a rim 25 engaging in a socket in a member 26 carried by the cylindrical member 21, extends on both sides of the saw-shaft and projects beyond one side of the tractor so that lengthy ripping may be undertaken. In another form, the saw has a single position on the saw-shaft and the ripping table is removably fitted over the swinging cross-cutting table. In a further form, the saw is positioned with its axis parallel to the longitudinal axis of the tractor. The ripping table is mounted transverse the main frame and the cross cutting table over the ripping table and just outside the outside wheel of the tractor, being removable by folding sideways.

Abstract: 885,290. Valves. DUNLOP RUBBER CO. Ltd. April 22, 1958 [May 1, 1957], No. 13811/57. Class 135. [Also in Group XXXII] In a damping valve assembly for a vehicle hydro-pneumatic suspension unit 1, Fig. 1 (see Group XXXII), valves 36, 39, held against seats 35, 48 by springs 40, each have a baffle 43. When a piston 5 moves up a cylinder 6, baffle 43 blocks holes 45 in the valve 36 and pressure of hydraulic liquid lifts this valve. Liquid flows around the valve 36 and through holes 45 in valve 39. As the piston 5 descends in the cylinder 6 the valve 39 is closed by its baffle 43 and is lifted off the seat 48. Fig. 3 shows an embodiment in which valves 107, 107a are urged against seats 105, 104 by springs 112, 112a respectively. As hydraulic liquid is forced upwards through the valve assembly, baffle 121 closes holes 110 in valve 107a and hydraulic pressure lifts the valve off its seat. Liquid then flows through holes 110 in valve 107 and round valve 107a. When hydraulic liquid is forced downwards through the valve assembly the baffle 121 closes the holes 110 in the valve 107. A constant bleed passage is provided by way of apertures 117, 118 in a disc 115, an annular space 114, holes 111 and a passage 108 in the valve 107, an aperture 122 in the baffle 121 and corresponding orifices in the upper part of the valve assembly. This bleed passage may be adjusted by needle valves 119. Differential operation of the valves 107, 107a may be obtained by screwing up or down discs 115, 115a to alter the tension of springs 112, 112a. Specifications 868,825 and 885,291 are referred to.
