Title: Improvements in and relating to protection means against burglary and fire for safes, strong rooms, and the like
IPC: E05B65/00
Filed: 1925-03-23
Abstract: 231,851. O'Brien, M. C. M. March 23, 1925. Valves actuated indirectly.-Relates to a pressure-operated bolt locking system for safes, strong-rooms, &c. combined with burglar and like alarm devices. Figs. 3 and 4 shows a safe, the walls of which are constructed to form two independent cavities 6, 7. The door has two similar cavities 9, 10. When the door is closed, pressure is admitted through specially-constructed bolts 12 from each cavity in the main walls to the corresponding cavity in the door. The bolts 12, one of which is shown in detail in Fig. 9, are fitted in pairs within the cavities 9, 10 of the door, and those in each pair are movable simultaneously in opposite directions. The locking movement of all the bolts 12 is effected by a single hand-wheel 17, Fig. 4. When the bolts are fully shot, with their heads 30 engaging in sockets 40 in the safe walls, valves are opened to admit pressure from the cavities 6, 7 through the bolts to the door cavities. Thereupon diaphragm bolts 92, Fig. 5, or the like, fitted around the door, are forced into locking engagement with recesses in the walls.

Title: Material sorting
IPC: A01D33/04
Filed: 1973-02-20
Abstract: 1423552 Separators for solid materials GEC MEDICAL EQUIPMENT Ltd 18 Feb 1974 [20 Feb 1973] 8249/73 Heading B2H A mechanism for separating e.g. root crops from stones &c, comprises at least one separating unit including a pivoted finger 1, e.g. of nylon 66, capable of moving between a first position (shown in dotted lines) and a second position (shown in full lines) and arranged to lie in the path of a mixture to be separated when in the first postiion, power means 3, 4 for maintaining the finger in the first position when energised and a spring 6 for causing movement of the finger to the second position to effect a separating operation upon selective de-energisation of the power means. The power means consist of a pneumatic piston and cylinder arrangement having an admission port 8 for compressed air fed from a manifold 12 via a flow restriction member 14, a chamber 15 and a valve 5 which is normally open to cause the piston 3 to maintain the finger 1 in the dotted line position in which material falling on it is deflected. When a detector associated with the separating unit detects an unwanted component of the mixture a signal is passed to the valve 5 along a lead 11 to close the valve, thereby disconnecting the port 8 from the manifold 12 and connecting it to an exhaust passageway 9 provided between the cylinder 4 and a block 10. This produces a rapid drop in the cylinder 4 and allow the force exerted by the spring 6 to retract the finger to the full-line position. Air exhausted through the passageway 9 and to which a lubricant may be added, is directed on to interacting surfaces of the finger 1 and piston 3 and of the finger and pivot 2 to reduce settlement of dust on these surfaces. A cover 16a, 16b surrounds the spring 6 and the finger 1 and has a slot 18 to allow movement of the finger, air being evacuated through the slot to exclude dust and dirt. The block 10 has a bore 30 for receiving a tie rod so that a number of separating units may be connected together side by side.

Abstract: 873,231. Reversing and regulating valves for thermal regenerators. KOPPERS G.m.b.H., HEINRICH. March 14, 1953 [March 16, 1957], No. 8354/58. Class 64(1) Reversal apparatus for a regenerative coke-oven battery having sudivided regenerators the sections of which communicate with individual sole flues leading to a single reversing valve 1 for each regenerator includes a regulating flap 21 disposed adjacent to a partition wall 18 separating pairs 2, 3 of the sole flues and operable with the valve on reversal selectively to throttle such flues. Thus in the position depicted in full lines in the drawing, the cross-sectional area of the sole flue 3 leading to the inner regenerator section is open and the tendency of the waste gases to flow preferentially to the outer regenerator section is suppressed by the throttling of the sole flue 2. However on reversal when the air flap 7 is open and the waste gas valve 6 closed the tendency for the inflowing air to flow preferentially to the inner regenerator section is suppressed by the throttling of sole flue 3 by flap 21. By means of a clutch (not shown) provided on the air flap pivot shaft 8, the air flap may be kept closed when the regenerator is used for pre-heating lean fuel gas supplied through a valve controlled connection (not shown) in the reversing valve body.

Abstract: 589,853. Automatic control systems for electricity supply. BRITISH THOMSON-HOUSTON CO., Ltd. May 26, 1943. No. 8422. Convention date, May 26, 1942. [Class 38 (iv)] Voltage.-Where a number of independently voltage-regulated circuits 1 supply a load through a line 4, the impedance of which is substantially constant and the regulators are provided With line drop compensators 14 to maintain a constant voltage at the load, the action of the compensators is rendered independent of the number of circuits in operation. For this purpose auxiliary current transformers 20 are connected in the compensator circuits 14 so that the current flowing in the latter may' remain the same when one or more of the parallel circuits are rendered inoperative; e.g. by the 'opening of one or more switches 6. The main current transformers 9 are arranged each in series with further auxiliary current transformers 16, the secondary windings of which are connected in series through conductors 15, 17 and the secondaries of the transformers 20 are also arranged in series through conductors 15 and 21. Short circuiting switches 24 are provided for the secondaries and when a circuit 1 is disconnected and the corresponding switch 24 closed the transformers 20 act to cause the increase of current from the remaining operative transformer 9 to be diverted through an equalizing conductor 22 connected to the junctions of the transformer 16 and 20. Regulating transformers 5 are controlled by voltage windings 10 energized from transformers 8 and connected in series with the line compensators 14 and transformers 13 for eliminating circulating currents in the circuits 1. Regulating and temperature changes are compensated by condenser and reactors 12. The invention is also applicable to loads supplied through three single-phase transformers in delta with provision for open-delta working by removal of one transformer. The circuits 1 may be fed by individual dynamo-electric generators. Any suitable regulators may replace the regulating transformers 5.
