Abstract: 591,291. Motor-vehicle driving-mechanism. TIMKEN-DETROIT AXLE CO. March 20, 1945, No. 7017. Convention date, March 1, 1944. [Classes 79 (ii) and 79 (iv)] [Also in Group XXIV] Motor-vehicle driving- mechanism comprises a change-speed gear, a differential driven directly from the change-speed gear and which drives wheel axles arranged in a plane above the axis of the differential, and a power take-off shaft driven from the gearbox input shaft, the whole being mounted in a common housing divided into compartments. A second power take-off provided with a disconnectible drive may be arranged to drive an auxiliary such as an oil pump. The clutch shaft 14, Figs. 1 and 2, projects into the housing 11 and is coupled by a splined collar 68 to the input shaft 56 of the gear-box. The shaft 56 has splines 59 on which are slidably mounted two gear clusters 60, 61. The gear cluster 60 comprises two gears 80, 81 and is moved by a selector fork 84, and the gear cluster 61 comprises two gears 85, 86 moved by a selector fork 88 (see Group XXIV). The gears 80, 81, 85 and 86 are engageable with the gears 74-77 respectively, to give 1st, 2nd, 3rd and 4th speeds, the gears 74-77 all being last on tne shaft 71, which terminates in a bevel pinion 73 in the compartment 50 which houses the differential. Reverse gear is obtained by interposing an idler pinion (not shown) between the gears 81 and 74. The bevel pinion 73 drives through the differential the pair of sleeves 136 mounted on the shaft 118, each sleeve 136 being formed with a pinion 138 in engagement with a gear rim 176 shrunk on to a hub 175 secured to each half-shaft 173. Each sleeve 136 terminates in a brake drum 145, the associated brakes 156 being operable independently so as to assist the normal steering of the vehicle. Projecting from one side of the compartment 11 is a housing 29 for the power take-off shaft 31 which is driven at its inner end by bevel gears 36, 65 and carries a pulley 39 at its outer end. Provision is also made for driving an auxiliary, e.g., an oil pump 209, from the pinion 68, by a disconnectible drive comprising a gear 224 slidably mounted on the splined sleeve 217 which is rotatably mounted by means of roller bearings on the fixed spindle 207. Fast with the sleeve 217 is a pair of cams 216 which actuate the oil pump 209 through levers terminating in rollers 215 bearing against the cams. The compartment 50 is filled with oil through an orifice 193 to the level O. The bearing 48 at one end of the gear box shaft 56 is lubricated from a trough 194, and the bearing 58 at the other end by a trough 195. The outer bearings of the power take-off shaft 31, of the half-shafts 173 and of the differential sleeves 136 are provided with oil seals, and the outer bearings of the half-shafts are lubricated by oil passing through passage ways (not shown) adjacent the inner bearings 184.

Patent GB-397783-A (GB)
Title: Improvements in and relating to temperature control means
IPC: G05D23/275
Filed: 1933-03-08
Abstract: 397,783. Fluid-actuated valves. KNEPPERS, J. M., 35, Stadhouderslaan, Utrecht, Holland. March 8, 1933, No. 7042. [Class 135.] Valves controlled by pilot or relay valves.-Apparatus for thermostatically controlling the flow of a heating or cooling medium comprises a mercury thermometer 1 which on rise of temperature successively shorts by means of contacts 2 .. 5 portions of a resistance 6 connected to the grid 7 of a thermionic valve and so decreases the grid potential. The resulting fall in the anode current of the valve weakens the field of a motor 11, the field coil 10 of which is in the anode circuit of the valve and so causes a rise in speed of the motor. The motor drives a governor 12, which controls a relay valve 14 controlling the operation of the main valve 18. When the valve 14 is lifted by the governor on increase of speed it allows passage of the fluid from a chamber 16, thus diminishing the pressure above a piston 17 and allowing it and the valve 18 to rise, thus diminishing the flow of the heating or cooling fluid. A falling temperature causes an increase in potential of the valve grid 7 and hence a rise in anode current, a decrease in speed of the motor and governor, a closing movement of the relay valve 15, and finally an opening movement of the valve 18.

Title: Hermetic closure for preserve jars and the process of and machine for making the same
IPC: B67B3/02
Filed: 1926-03-15
Abstract: 249,513. Hietzgern, G. March 20, 1925, [Convention date]. Capsules and the like, applying. - Preserve jars are hermetically closed by a machine comprising two buffer springs, one disposed between the jar-supporting plate and its adjusting spindle, and the other, more powerful spring, between the pressing head and its actuating mechanism. The machine applies to the mouth of the jar a cover plate 1 and a sealing ring 3 the lower edge of which is provided with tongues or lugs 5 adapted to be uniformly and simultaneously forced by a steady pressure against the flange of the jar. A jar 14 is placed on a rest 13, the stem of which is guided in a hollow spindle 10 adapted to be screwed through a bracket 9 on the frame 8 of a sealing-machine, a buffer spring 12 being interposed between the end 15 of the spindle and the rest 13. By rotating the spindle, the jaw is raised until its mouth projects through a table 6 having mounted on it a die-carrier 18 which comprises two parts hinged together so that they may be opened out to admit the jar and afterwads closed, the parts being then locked together by a hook 23 pivoted to the fixed part of the carrier and constituting one arm of a bell-crank lever 23, 24. The die is formed in two parts to correspond to the carrier and is made removable therefrom to adapt the machine for use with jars of different sizes. To bend the tongues of the ring 3 beneath the flange of the jar, the jar is thrust downwards in the die by a pressure head 28 mounted on a rod 27 adapted to slide in a guide 26 secured to the framing 8. The rod is actuated by a handle 38 pivoted to the guide 26 and connected by links 37 to a sleeve 35 on the rod 27, the sleeve engaging through a buffer spring 34 a stop 33 fixed to the rod. The spring 34 is stronger than the spring 12 which supports the rest 13. As the pressure head moves downwards, a spring-pressed lever 30 pivoted on a projection on the head is displaced upwardly by a knob 25 on the arm 24 of the bell-crank lever 23, 24 but as the head is raised after the sealing an abutment on the lever 30 prevents it from being lowered when the knob 25 strikes it and the knob is therefore thrust aside turning the arm 24 and unlatching the hook 23. When the contents of the jaw are to be heated or sterilized, the tongues 5 are only partly bent beneath the flange, the complete bending being effected after the heating &c.

Title: Improvements in or relating to sealing devices for blowers and like machines
IPC: F04D29/10
Filed: 1961-02-28
Abstract: 959,461. Liquid and gaseous seals. COMPAGNIE ELECTRO-MECANIQUE. Feb. 28, 1961 [March 1, 1960], No. 7249/61. Heading F2B. The shaft 2 of a gas blower 1 is sealed by means of an oil seal device 6 in combination with a gaseous seal device 7 which is fed with a sealing gas having a density greater than that of the gas circulating through the blower, a radial pressure-gradient being established in the gaseous seal device by means acting on the sealing gas for isolating completely, under normal operating conditions, the gas of the blower from the oil vapours likely to escape from the oil seal device and for detecting, under abnormal operating conditions, any oil leakage towards the blower. The shaft 2 is supported horizontally in bearings 3, 4 and carries an impeller 1a The sealing device 7 consists of members 10, 11 secured by tie-rods 14 and constituting a chamber in which a disc 9 mounted on the shaft 2 revolves and subjects the sealing gas to centrifugal force so that a difference in pressure is produced radially in the chamber between the base and the periphery of the disc. The sealing gas, which may be different from that in the blower, or may be the same gas previously cooled in a heatexchanger 15, is fed through a pipe 17, a chamber 18 and a duct 19, which may all be heat-insulated or jacketed, to the chamber of the sealing device 7 which may be cooled. Oil is circulated under pressure in the oil seal device 6 and returns through a chamber 27 and a duct 24 to a tank 25 kept under pressure by an automatic drain valve 26. The duct 24 is provided with a discharge valve 23 controlled by a regulator 22 connected to the chamber 7 through ducts 20, 21 opening respectively in front of the base and periphery of the disc 9. A regulator 28 actuating an alarm or corrector device 29 is connected to the duct 20 and, through a duct 20a to the chamber 27. A labyrinth packing 8 is provided between the sealing devices 6, 7. In normal operation oil flow in the sealing device 6 is adjusted by the valve 26 so that the pressure in the chamber 27 is approximately equal to that in the blower. If due to a rapid pressure drop in the blower or to faulty operation of valve 26 oil is drawn from the chamber 27 into the chamber 7, the consequent increase in pressure differential in the latter will cause the regulator 22 to open the valve 23 until the oil is forced back from the chamber 7 into the chamber 27. Should the pressure in the chamber 27 drop abnormally due to faulty operation of valve 26, the consequent pressure differential set up between either side of the packing 8 due to passage of gas from the blower to the chamber 27 will cause regulator 28 to actuate the alarm or device 29 with a view to adjust valve 26. French Specification 1,147,053 is referred to.
