Title: Improvements in or relating to telephone systems
IPC: H04Q3/62
Filed: 1937-05-05
Abstract: 491,612. Exchange systems. ERIC. SSON TELEPHONES, Ltd., and DISTIN, L. S. May 5, 1937, No. 12829. [Class 40 (iv)] A supervisory relay is connected in series with the line and is associated with a fullwave rectifier so that it responds to prolonged interruptions of the line current, but not to current reversals or dialled impulses. In the system shown, the operator at a cordless P.B.X. switchboard sets up an outgoing call by looping the junction via keys KA, KS and dialling in the usual way, and completes it to the calling subscriber by operating a key such as KE. Supervisory relay S is associated with the line and with a rectifier bridge so that it remains operated continuously and holds indicator IR disconnected until the calling party hangs up. Incoming ringing current operates an indicator ID which locks up. When the call is answered, S pulls up over the loop in the operators' circuit, releases ID and subsequently holds over the called subscriber's loop to keep IR disconnected until the called subscriber hangs up.

Title: Improvements in or relating to safety systems for mine hoist installations
IPC: B66B17/20
Filed: 1958-04-25
Abstract: 891,128. Mine cages. RHYMNEY ENGINEERING CO. Ltd., and PARSONS, G. W. July 8, 1959 [April 25, 1958], No. 13281/58. Class 78 (4). A mine cage 2 is fitted with a device for proving the position of a mine car 4 in it, and for giving a warning, or preventing movement of the cage, if the car is incorrectly positioned. In the form illustrated chocks 16 engage the sides of the wheels, instead of the rail 3, if the truck is wrongly positioned. The chocks are normally held against the rails 3 by a spring 18 acting through a rod 7 and a linkage 8, 13. The chocks are retracted, when the cage is at the decking level, by an arm 10 connected to the rod 11 and bearing a roller 12 which engages a hanging plate 21 pushed to the right in Fig. 2 when a ram 28 is operated to release the chocks. This action releases a limit switch 32 operated by a roller 31 bearing on the plate 21. The switch 32 is closed, indicating that the cage can be wound, only when the ram 28 is retracted and the chocks 16 have returned to their locking positions. The ram 28 acts on the plate 21 through an arm 25 and roller 26, and the normal position of the plate 21 may be altered by adjusting a balance weight 22. The chocks 16 may be replaced by feelers engaging the side of the car. The invention may be applied to cages having more than one deck.

Title: Electro-hydraulic actuator mechanism
IPC: F15B15/18
Filed: 1967-03-22
Abstract: 1,128,868. Valves. ITT INDUSTRIES Inc. 22 March, 1967 [30 March, 1966], No. 13463/67. Heading F2V. [Also in Division F1] An electro-hydraulic actuator especially for operating valves has an actuator piston 90 slidable in a cylinder 36 formed in the central portion of a main casting 16 having a cavity to one side of the cylinder which is closed by a housing 22 to form a reservoir for hydraulic fluid supplied to the cylinder 36 by a pump 58 driven by an electric motor 56, the motor and pump being mounted in the reservoir. The pump 58 has a cylinder 62 screwed into a socket 60 integral with the housing 22 and a piston 64 reciprocated in the cylinder 62 by an eccentric 66 driven by the motor 56. The output of the pump is adjustable from outside the housing 22 by rotation of a shaft (86), Figs. 4 and 5 (not shown), having a pinion (84) meshing with a gear (82) provided on the cylinder 62 which is thus axially adjusted. Fluid enters the cylinder 62 through a side wall port 70 and is discharged past an outlet valve 72 and through passages 74, 76, 101, 104 in the housing 22, main casting 16 and a cylinder end cover 18 into the top of the cylinder 36. The housing 22 may be inverted, Fig. 8 (not shown), whereby fluid is pumped to the bottom of the cylinder 36 through a passage 106 to cause upward movement instead of downward movement of the piston 90 against a spring 94 for the return stroke. A lever 134 pivoted by a cross-pin 136 of the piston-rod 92 may be connected by external linkage to e.g. a further valve. Projections 146 on the piston-rod 92 may operate switches 138. To perform the return stroke an electrically operated by-pass valve 80 is opened with the pump stopped. The piston may be held in mid-stroke by leaving the pump running and partially opening the bypass valve.

Patent GB-134943-A (GB)
IPC: C21B7/00
Abstract: 134,943. Esperhahn, E. V. Nov. 15, 1917, [Convention date]. Sulphur.-Sulphur dioxide contained in commercial waste gases is absorbed in a solution of alkali thiosulphate, and the polythionates produced are in part reconverted into thiosulphate for continuing the process (sulphur being precipitated), and in part heated to 90-100‹ C. to produce sodium sulphate, sulphur dioxide, and sulphur. If this treatment is carried on so that the sulphur dioxide is maintained in intimate contact with the solution, for instance by using pressure, the formation of free sulphuric acid is facilitated and more sulphur is precipitated, the liquor being then neutralized with sodium sulphide with further formation of sulphur. The sodium sulphide required for the regeneration of the thiosulphate &c. is obtained by the reduction with carbon of the sodium sulphate produced as described above, and a solution of the sodium sulphide may be used to mix with saturated sodium sulphate solution to cause the precipitation of sodium sulphate and avoid evaporation. Alternatively, sodium sulphate may be obtained from an outside source, for instance nitre-cake or salt-cake, and reduced with carbon, the sodium sulphide being used as above described for regenerating the thiosulphate, and in that case thiosulphate accumulates and may be withdrawn as a product of the process.
