Title: Improvements in or relating to vertical closing devices for operating a sliding gate of a skip employed in a guided skip hoist
IPC: B66B17/14
Filed: 1955-11-17
Abstract: 825,839. Operating doors of skips in shafts. GUTEHOFFNUNGSHUTTE STERKRADE A.G. Nov. 17, 1955 [Nov. 25, 1954], No. 32913/55. Class 78 (4). A driving member 17, Fig. 7, moved along a straight vertical path to open the sliding gate 2 of a skip to a skip hoist also has a movement at right angles to the vertical path into and out of position to engage the gate, which latter movement is derived from the vertical movement. The member 17 shown in Fig. 7 is pivoted about an axle 19 to a carriage guided by wheels 20 in guides 21. Normally the driving member 17 hangs in the retracted position shown in broken lines towards the bottom of Fig. 7 but as the gate 2 rises a lug 4 on it engages a member 18 also carried by the spindle 19 and guided by rollers 22 in the tracks 21 so that the carriage is raised. As the carriage rises a guide 23 engages a roller 24 on the member 17 to move it into engagement with the lug 4 so that when the skip has stopped, and a ram (not shown) raises the carriage further, the door 2 of the skip is slid open. The member 18 subsequently provides a positive drive to close the gate 2. Should the skip be over-wound the rollers 22 escape at 21<SP>1</SP> from the guides 21 to retract the member 18 out of engagement with the lug 4 as shown in broken lines towards the top of Fig. 7. The connection between the carriage and its operating ram preferably includes lost motion. In the alternative construction of Fig. 2 a carriage 7 raised by a ram (not shown) carries a pair of sectors 5, 6 pivoted at 8, 9 and controlled by rollers 15 engaging in guides 14, 13 so that the sectors are swung ouwardly to engage a lug 4 on the sliding gate 2 of the skip as the carriage 7 is raised. When the carriage 7 is again lowered to close the gate 2 the sector 5 is retracted by the roller 15 engaging the track 14 while the sector 6 is retracted by engagement of a further roller 6<SP>11</SP> on it with a cam track 16 on the gate 2.

Title: Improvements in turbo compressors
IPC: F04D29/40
Filed: 1925-12-31
Abstract: 246,123. Akt.-Ges. Brown, Boveri, et Cie. Jan. 16, 1925, [Convention date]. Leaking-preventing devices; casings.-The possible sources of leakage in a centrifugal compressor are protected by chambers in which a reduced pressure is maintained. The arrangement is applied to compressors for noxious vapours. The two units 1, 2 of a compressor for a refrigerating plant are enclosed in casings 6, 7, and are connected to an intercooler 5. A fan 12 driven with the compressor keeps the pressure in the casings 6. 7 slightly below atmosphere pressure. The casings may also enclose auxiliary apparatus such as the cooler 5. With this arrangement air may travel into the casings, but gases cannot escape from the casing into the atmosphere. All the pump units may be arranged in a single casing and its pressure reduced by an ejector or a chimney. Any stuffing boxes employed are inside the casing so that they need not be absolutely tight. Where protection against leakage between abutting flanges is to be provided, passages 19, Fig. 5, are formed in the flanges and the holes for the bolts 22 are connected to the passages 19 by subsidiary channels 23. The system of passages is connected to pressure-reducing apparatus. When ejectors are used to reduce pressure the liquid used should be one in which the gas in the compressor is soluble, to enable recovery to be effected.

Filed: 1973-07-13
Abstract: 1474021 Electronic timepieces SMITHS INDUSTRIES Ltd 4 July 1974 [13 July 1973]  33480/73 Heading G3T An electronic timepiece for the timed control of an electrical appliance(s) and which may also indicate time of day, is normally energized from and synchronized with an A.C. mains supply, but is provided with means (energized by a battery) for generating a cylically varying timing signal which is used in the event of failure of the mains supply. In Fig. 1, a unit 10 provides a 5À6V D.C. on a line 12 via a rectifier 39 to a battery 13 and a pulsiform signal on a line 18 at the mains frequency of 50HZ. During normal operation a gate circuit 17 (detailed in Fig. 2 (not shown) is biased by the D.C. signal in line 12 to pass the 50HZ pulses to a frequency divider networks 19 which produces pulses in a line 20 at 25HZ and pulses on a line 22 at 0À5HZ. The pulses on lines 20, 22 are converted by a drive unit 21 into two trains of 0À5HZ pulses, having a pulse width of 20 m. sec. and the pulses of one train occurring mid-way between those of the other, which pulse train drive a stepper motor 25. The motor rotates a timing disc 26 once every twenty four hours via gears 27. A tappet 28 thereon operates to close a switch 30 which is in turn opened by a tappet 29. When the switch 30 is closed a relay 32, 33 connects an appliance(s) to the supply mains. Upon mains failure the gate circuit 17 is biased to pass 50HZ pulses from an oscillator circuit 15 to the divider circuit 19 to drive the stepper motor. The motor may also drive time of day indexing mechanism. Alternatively, to save the battery power the motor and indexing mechanism 25-30 may be rendered inoperative and an electrical up/down counter used to count up the oscillator pulses  during the whole period of mains failure. When the mains are restored the counter counts down to provide pulses which are added to and interlaced with those produced by power supply unit 10 whereby to update the indexing mechanism.
