Title: Hydraulic transmission system
IPC: E02F9/22
Filed: 1961-06-19
Abstract: 909,169. Hydraulic brakes. YALE & TOWNE MANUFACTURING CO. June 19, 1961 [July 13, 1960], No. 22004/61. Class 103 (1). [Also in Groups XXIX and XXXI] An hydraulic transmission system has a variable displacement pump P driven by engine E and connected to hydraulic motor M for driving ground engaging wheels W, control means C responsive to pressure changes in the circuit between pump P and motor M for increasing the pump displacement as pressure in the circuit decreases, and overriding means 93, 95 for decreasing the pump displacement independently of means C. With reversing valve R in the shown forward drive position, liquid from pump 13 is supplied to chamber 58 of control C, Fig. 2, to piston 54 which through a non-linear spring 56 rotates lever 46 about a fixed stud 48, a chamber 57 being connected via valve R to reservoir 12 enabling piston 55 to be depressed. Lever 46 operates valve Vs via rod 51 to supply fluid to the left-side of piston 114, which moves and through rod 115, a link, and arm 30 adjusts the pump swash plate 26. Liquid is delivered via pipe 10 to motor M which drives wheels W via differential 154 and gears 146, 148, 152, 158. The liquid returns to pump P through pipe 11. Increase in load on motor M increases the pressure in pipe 10 which moves a piston 81, Fig. 2, to pivot lever 46 counterclockwise until balanced by spring 56 to actuate valve VS and servomotor S to decrease the displacement of the pump P and hence increase the torque from motor 17. Decrease of load produces a decrease in pressure in pipe 10 and increase in pump displacement. Should motor M drive pump P and engine E, the pressure in pipe 10 decreases, and spring 56 moves lever 46 for maximum displacement of the pump and minimum braking effect by the pump and engine. For maximum braking operation of master cylinder P raises piston 93 of control C to force a yoke 96 against arm 45 to move lever 46 anticlockwise to decrease the pump displacement. Further actuation of the master cylinder pressurizes brake cylinder D to apply shoes 156, 157 to drum 155. For reverse drive, valve R is moved to the left to raise piston 55 and lower piston 54 ; lever 46 rotates clockwise to actuate valve VS to move piston 114 to the left and reverse the flow from the pump, the line 11 being the supply line and line 10 the return line. The pump displacement is controlled as before except that a piston 90 is raised or lowered by pressure changes in pipe 11 to adjust lever 46. Braking is as above. Pressure relief valve 159 and shuttle valve 160 prevent the build up of excessive pressure in pipe 10 or 11.

Abstract: 731,842. Electric follow - up systems. VICKERS - ARMSTRONGS, Ltd., and METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. Aug. 17, 1953 [Sept. 2, 1952], No. 22076/52. Class 40 (1). The error signal amplifier in a follow-up control system includes a phasechanging circuit for retarding the phase of and attenuating oscillations of the error signal below a particular frequency and for advancing the phase of and attenuating oscillations above this frequency. The error signal input Vi is applied at 7, 8, Fig. 2. For frequencies below the particular frequency the parallel connected condenser 11 has less effect relatively than the series connected condenser 14 and vice versa for frequencies above the particular frequency, so that for the two frequency ranges in question the circuit functions as a phase lagging and leading arrangement respectively and attentuates the signal in both ranges. The invention is described, Fig. 1 (not shown), for driving a load by a hydraulic-swash-plate motor the angulation of the swash plate being servo-controlled through a Selsyn system, and may be applied to the control of naval guns.

Abstract: 248,649. Speck, T. R. Dec. 4, 1924. Charging and discharging; cooling discharged materials.-In a continuous furnace for annealing or tempering metals, the charging means is adapted to operate in two stages, the first movement being a direct manual one, employing no device giving a mechanical advantage, to move the charge quickly from a loading chamber 1 into the entrance to the heating chamber 2, and the second a mechanically effected movement to feed the charge into the heating chamber with consequent discharge of the end charge into the sealing tank 17. The loading chamber 1 is fitted with a charging ram 4 carried by a screwthreaded rod 5 which slides in a plain bearing 6 and carries a traversing nut 7, the latter being fitted with operating handles 8 and a pivoted clutch lever 9, Fig. 7, notched at 11. In operation, a container 13 is fed through the loading door 14 and after the counterweighted door 15 has been opened, the ram 4 is pushed inwards by hand to move the container 13 into contact with the previously-charged container 13a, Fig. 5; the final movement into the heating chamber is effected by rotation of the nut 7 after the lever 9 has been rotated so that the notches 11 engage over pins 12 provided on the furnace frame. Release of the lever 9 permits a quick withdrawal of the ram 4, this movement effecting expulsion of air from the loading chamber and replacement by inert gas from the heating chamber.

Title: A welding circuit
IPC: B23K9/20
Filed: 1966-05-20
Abstract: 1,119,684. Stud welding systems. OMARK INDUSTRIES Inc. 20 May, 1966 [20 May 1965], No. 22622/66. Heading H2H. A gravity drop percussion stud welder receives its energy from one or more capacitors 102, charged from a rectifier 28 through a thyristor 142 fired by closure of relay contacts 140, to a voltage determined by the setting of a resistor 154 forming part of a potential divider. A fraction of the capacitor voltage is compared with that due to a Zener diode 130 through a transistor 136 which when rendered non- conductive de-energizes a relay 138, 140. If this circuit should fail and the capacitor voltage rise further a Zener diode 174 operates a relay 176 having contacts 54 which causes a fuse 42 to blow. The capacitor discharge is initiated by spaced apart manual switches having contacts 64, 68 in series and 66, 70 in parallel, all in series with a relay coil 88 having contacts 90 and arranged so that both. switches must be closed before coil 88 is energized and both must be opened before coil 88 is released. A second pair of contacts 92 control through coil 94 of an electro-hydraulic valve, the admission of fluid to a workpiece clamp (not shown). A third pair contacts 112 through contacts 110 of a stud holder limit switch in the up position, energizes a relay 106, 108 to connect the capacitors to the stud holder 98. On closure of other contacts 118, 122 operated by relay coils 88, 108 another electro hydraulic valve coil 120 is energized allowing the stud holder to move downwards.

The toe and heel portions of a footwear upper are moulded simultaneously with the stretching of the upper longitudinally to a predetermined extent, the moulded upper subsequently being attached around its periphery to a sole member. The lower edges of the above portions may be flanged either inwardly or outwardly in the same moulding operation. The moulding is effected under heat and pressure with the aid of a thermosetting stiffening composition such as urea-formaldehyde cement. In one arrangement the inner face of the upper is constituted by a pad of fabric attached to the outer upper material and this is impregnated with the stiffening composition moistened with a setting agent prior to moulding. A suitable machine comprises a main frame 6 to which is pivotally secured at 17 a forward frame portion 21 which may be swung to left or right to accommodate left or right hand shoes. Mounted on frame 21 is a clamp 14 in which is clamped the toe portion of the upper to be shaped. An inner toe mould 4 is mounted on a link 13 with an associated link 2 for keeping the mould level. Link 13 is pivoted to a further link 3 carrying a roller 7 engaging a cam track 8 having a yieldable spring-loaded stop 9. Link 3 is also guided by a pin-and-slot mechanism 12 and is pivotally linked to a handle 10 so that the mould 4 can be moved along the path 6a into a preformed upper. Separately mounted on frame 6 for forward and rearward movement is a carriage 31 for an inner heel mould 26. This is moved rearwards during the moulding operation by a linkage system 29 and held back by a ratchet, the operatinghandle 28 of which can be released to allow the carriage 31 to move forwards under the influence of a return weight 30. Separately mounted on frame 6 is an outer heel mould 19 which can also be moved forwards and rearwards and which carries a removable cam-operated heel wiper mechanism 22. The inner toe mould 4, the inner heel mould 26, the clamp 14 and the heel wiper mechanism are provided with heaters. If desired, the inner toe mould 4 may be supplemented by an outer mould to embrace the top of the upper. After a moulding operation, the inner toe mould 4 can readily be lifted out of the moulded toe by rearward movement, the stop 9 yielding under this movement to allow the roller 7 to move past.
