Title: Improvements in or relating to padlocks
IPC: E05B37/02
Filed: 1944-08-31
Abstract: 581,533. Padlocks. ROSENFELD, P. W. Aug. 31, 1944, No. 16580. [Class 44] A padlock with permutation locking mechanism has a spring-controlled shackle held in closed position by the engagement of an abutment thereon with a ball which can only move when a radial slot in a rotating disc (or slots in two or more discs) is or are aligned with a radial slot in the casing. The disc or discs turn about the ball as a centre. The casing 1, Fig. 1, has a cover 2 rotatably secured thereto and bearing index marks. Below the cover is a disc 12, Fig. 4, with a radial slot extending from the centre to the edge, and a pin 14 which enters an annular groove in the cover 2. At one point in the groove is a pin which on rotation of the cover engages the pin 14 and enables the disc to be rotated. In the bottom of the casing 1 is formed a groove 17, Fig. 5, which when the slot in the disc is aligned therewith forms a guideway down which a ball 18 may roll. When in its central locking position, the ball prevents movement of a spring pressed abutment 25. The shackle 3 is of the type having a long and a short arm, rotatable when the short arm is disengaged from the casing about the axis of the long arm, and a part of the long arm between flanges 21, 22 engages in a groove in the abutment. When the slot in the disc and the groove 17 are aligned, the lock is tilted to cause the ball to roll away from the centre, and the abutment moves upwardly, releasing the shackle. In a modification, the rotatable cover 2 may also be provided with a radial groove in which the ball engages, so that the grooves in the cover and the casing and the slot in the disc have to be brought into register to permit the ball to move. As a further modification, rotatable covers may be provided on both sides of the casing, both having to be set to operate the lock. Altertively or in addition, more than one movable disc may be provided.

Title: An Invention for Checking and Registering the Number of Passengers Carried and the Amount of Fares Earned on Tramcars and other Public Conveyances.
Inventor: LAURIE WILLIAM SANDS
IPC: G06M3/14
Filed: 1916-11-23
Abstract: 111,336. Laurie, W. S. Nov. 23, 1916. Fares, seat-apparatus for checking and registering; distance-driven registers.-The passengers, as they enter public stage vehicles, pay their fares to the conductor, who assigns them to numbered seats which he unlocks by electric means; the fares are registered electrically according to the seats occupied and the stages. Each hinged seat p is normally locked in the position shown in Fig. 2, wherein it is pressed by a spring against the fixed back (not shown), by the abutment of a projecting lug m, n with a leverlatch s, t. Completion by the conductor of the electric circuit through the electro-magnet x, z of the seat selected by the entering passenger results in the depression of the latch, so that the passenger can put down the seat. As it is drawn forwards, a bare spot v, Fig. 3, upon an insulated curved copper rod g, h carried by the seat makes momentary contact with a spring stud e, thereby closing a main circuit containing an indicator or counter for the number of seats occupied or the number of fare-units corresponding thereto. The insulation of the rod is thickened at k in order to cause the contact to jump, when the seat springs up, without completing circuit. For journeys exceeding a single-fare stage, the second and following fare units are registered when the conductor, at the beginning of each stage, rapidly rotates a cylindrical switch f, Fig. 5, helically arranged pegs upon which make successive contact with spring plates b and force them against the common lead c. In this way, and by the provision of other contact-members (not shown), which remain in contact while the seat is fully depressed, a fare-unit is added upon the register for each seat occupied at the beginning of the stage. The conductor also announces the stages by strokes upon a gong and registers his operations of the multiple switch upon a counter. Alternatively, the multiple-switch may receive automatic operation from the running wheels of the vehicle at the beginning of each stage. Electric current may be supplied by storage batteries or from the track &c. conductors of electrically-propelled vehicles.

Title: An improved manufacture of lubricating oils
IPC: C10G21/02
Filed: 1942-11-26
Abstract: 564,195. Refining mineral oils. STANDARD OIL DEVELOPMENT CO. Nov. 26, 1942, No. 16777. Convention date, Oct. 4, 1941. [Class 91] In the production of a purified lubricating oil the crude oil is subjected, e.g. to distillation to separate a " heart-cut " fraction having a viscosity in the range of about 10 to 140 Saybolt seconds at 210‹ F. which is then subjected to selective solvent extraction in a primary zone, and the raffinate therefrom to a second selective solvent extraction in a secondary zone with a solvent having higher solubility for mineral oil than the first solvent, the purified lubricating oil being recovered from the secondary solvent. The oil obtained is relatively narrow in both viscosity and viscosity indexrange. The oil-solubility of the secondary solvent may be increased over that of the first solvent by using the same solvent at a higher temperature, using a different solvent, or by using a modifying solvent in either of the extracting zones, or by a combination of any of these variants. When using different solvents, the order of increasing solubility at the same temperature of the more usual ones comprises aqueous phenol, furfural, aniline, anhydrous phenol, #-#<1>-dichlordiethyl ether, cresol, and nitrobenzene. In an exemplified procedure, the pairs of solvents comprise aqueous phenol and anhydrous phenol, anhydrous phenol and aqueous phenol or methylalcohol-phenol at a higher temperature. In a suitable plant for effecting the process, a lubricating oil distillate of the narrow viscosity range defined is taken off through line 9 from an intermediate position of a vacuum pipe still 5, the petroleum oil being previously distilled in an atmospheric pipe still 1 and the light and heavy fractions being taken off from both stills, and the narrow viscosity range distillate is introduced to a de-waxing zone 10 and then to the initial solvent extraction zone 13, the raffinate from which is supplied by line 16 to the secondary extraction zone 17. The usual countercurrent flow is used in both extraction zones, and the final extract solution is removed through line 18, freed of solvent and clay treated in zone 21 to obtain the desired purified lubricating oil. The de-waxing step may be omitted, the wax then being removed with the second raffinate through line 20.

Abstract: 964,714. Testing ground permeability in situ. SOLETANCHE. May 9, 1961 [June 1, 1960], No. 16843/61. Heading G1S. Apparatus for testing the permeability of ground in situ comprises a bell 5 supported within a bore-hole by a ball 6 closing an aperture at the top of the bell when cable 4 is in tension, the cable passing over a graduated pulley 3 and carrying a counterweight p which balances the weight of the bell when the latter is totally immersed in water (all the air having escaped during immersion when the cable is slack), a further counterweight P being then attachable to cable 4 to raise the water-filled bell, on release of a holding stud 8, by a predetermined height. Water enters the borehole at a measured rate and the rising movement of the bell causes pulley 3 to rotate at a rate which is a function of the permeability of the ground at the base of the borehole.

Title: Improvements in or relating to prepayment mechanisms
IPC: G07F15/06
Filed: 1933-01-24
Abstract: 415,721. Prepayment mechanism for meters. BUTHERUS, F. R., and BRITISH SANGAMO CO., Ltd., Cambridge Arterial Road, Enfield, Middlesex. Jan. 24, 1933, No. 16856/34. Divided on 414,069. [Class 27.] In prepayment meter mechanism in which a fixed charge, such as rent, is collected by a constant speed motor arranged to operate the setting mechanism to cut off the supply of commodity, the coupling between the constant speed motor and the mechanism which it controls is such as to permit relative movement between the parts of the coupling the extent of which indicates the arrears of fixed charges that must be paid before a further supply can be obtained. The constant speed motor, through an adjustable drive as described in Specification 414,069, drives a gear wheel 29 fixed to a shaft 30 on which is frictionally mounted by a split plate 32 a ratchet wheel 31 engaging a pawl 33 on a toothed drum 34 which is loose on the shaft 30 but connected thereto by a spring 35. The drum through gearing 42, 43, 46 drives the sun-wheel 44 of a differential mechanism, the other sun-wheel 53 of which is rotated after insertion of a coin by prepayment mechanism as described in Specification 414,070. When the supply of commodity is cut off, the sun wheel 44 is locked against rotation, and the drum 34 cannot rotate. The constant speed motor then operates to wind up the spring 35, the split plate 32 allowing slip, and a pointer 39 on the shaft 30 indicates on a graduated dial on the front face of the drum the arrears of fixed charges. As coins are inserted, the wheel 44 in effect becomes unlocked and the spring 35 causes the drum to follow the pointer, the coins having no effect in setting forward the quantity mechanism until the arrears are paid off. When no arrears are due, the sun wheel 53 through a planet wheel 63 rotates a shaft 64, the drive being transmitted through change speed wheels 66 to a screw threaded shaft 68 and causing a wheel hub 76 to move away from catch mechanism as described in Specification 414,070. The meter rotor through gearing including a long pinion 75 rotates the nut 76 causing it to return to its initial position and trip the catch mechanism to cut off the supply. Rotation of the sun wheel 44 by the constant speed motor causes the shaft 68 to rotate in the reverse direction and the hub 76 to move towards its cutting-off position. Indicators.-Rotation of the shaft 68 causes rotation of a " units-unused " drum 81 relatively to a pointer 83 fixed to a shaft 82, the drum being loose on the shaft and connected thereto by a spiral spring. The shaft 82 is rotated from the meter and causes the pointer 83 to overtake the zero graduation on the drum. A pawl 105 locks the drum when the pricechange wheels 66 are being altered, so as to prevent movement of the wheel nut 76. Specification 347,794 also is referred to.

An envelope, for example of e discharging device, may be assembled and sealed to entrap a rarified atmosphere of hydroger as in the parent Specification but to reduce the internal pressure still further, at least a part of the envelope wall is made of a material which is pervious to hydrogen at an elevated temperature and which absorbs hydrogen at a lower temperature. Thus after sealing has taken place, the envelope is heated in a stream of rare gas, for example argon, so that said wall part allows hydrogen to escape from the envelope owing to the low partial pressure of hydrogen exterior to the envelope. After about 15 minutes, the time depending on the initial and final pressure of the hydrogen, the temperature and the wall thickness and area, the envelope is cooled whereupon said wall part absorbs at least part of the remaining entrapped hydrogen. The figure shows a suitable construction for a triode to be evacuated by the above method, it comprises ceramic spacers 24, 25, 26 interposed between metal terminal members 20-23. Terminal 20 may be integral with a disc shaped anode 27, terminal 21 is connected to planar grid 28, terminal 22 is connected to cathode sleeve 29 and terminal 23 to one end of cathode heater 30. One or more of the metal members may be of titanium or of the group comprising zirconium, hafnum, thorium, pallodium, vanadium. The components are stacked with a nickel washer between each metal and each ceramic member. When sealing takes place the nickel forms a reactive alloy with the titanium. Residual pressures of the order of 10-<SP>9</SP>mm. Hg. may be obtained by this method. Specification 813,829 also is referred to.-
