Title: Bolt Mechanisms
IPC: E05B63/00
Filed: 1980-03-19
Abstract: A bolt mechanism for the door 1 of a safe has bolts 11 which are thrown by a crank arm 3 turned by a spindle 2 connected to an external handle, the crank arm carrying a pin 7 which runs in a drive slot 8 in a bar 9 connected to the bolt strap 10. A plate 15 is carried by the bolt 13 of a lock 12 so that when the safe bolts 11 are thrown and the lock operated the plate 15 carries the crank pin 7 which engages in a slot 16 of the plate clear of the drive slot 8, the crank arm 3 being slidable transversely on the spindle for this purpose. This operation isolates the connecting bar 9 from the spindle to prevent the application of force to the boltwork through the spindle in the sense tending to withdraw the boltwork. <IMAGE>

Title: Improvements in or relating to bollards
IPC: E01F9/646
Filed: 1980-09-05
Abstract: A bollard suitable for use in road traffic control applications, for example to control or restrict the access of road vehicles into controlled zones, comprising a head portion 2, an anchor portion 1 adapted to be embedded in the ground, and fixing means 15 for fixing the head portion to the anchor portion in an upright position and in such a way that the head portion collapses in a predetermined manner when subjected to an impact above a predetermined magnitude. As disclosed, the head portion is pivotable between the upright position and a horizontal position on release of locking means. The bollard is preferably sufficiently rigid to withstand minor accidental impacts from both light and heavy vehicles without serious damage, and predetermined collapse is ensured by fracture of the fixing means thereby tending to avoid serious damage to the head or anchor portions as a result of a severe impact. <IMAGE>

Title: Hydrogen Sulphide Detector
IPC: G01N27/12
Filed: 1980-10-08
Abstract: A device for detecting the presence of hydrogen sulphide consists of a ceramic substrate (1) having on one face a semiconductive layer (5) and having on the other face a layer (6) of ferro-electric material. The layer (5) has an electrical conductivity which varies when it comes into contact with hydrogen sulphide, which variation can be detected by a measuring device connected to wires (3), and is a layer of sintered metal oxide having gold and platinum atoms disposed upon the individual metal oxide particles forming the layer. The device is heated by passing a current through the layer (6) to raise the temperature of layer (5) to a value at which the layer (5) is sensitive to the presence of hydrogen sulphide. <IMAGE>

Title: Continuous separation system
IPC: B01D33/00
Filed: 1980-10-20
Abstract: A separator 15 comprises a casing 22, a horizontal rotary screen 60 within the casing, a fixed scraper 140 mounted in the casing above the screen, an inlet conduit 25 on one side of the scraper for depositing slurry on the screen, an outlet conduit 40 on the other side of the scraper and gas nozzles for directing a gas stream at the solids as they encounter the scraper, entraining them, and directing them through the outlet conduit 40. The screen divides the casing 22 into upper and lower chambers 23 and 24. In operation, the gas stream carries the entrained solids to a separate receiver. The gas is then recirculated. The lower chamber 24 is evacuated so that a portion of the gas in the upper chamber passes through the slurry layer to displace liquid through the screen while further amounts of the gas cause additional drying of the solids. The recovered liquid is automatically degassified. <IMAGE>

Title: Improvements in pipe line shut-off valves with a leakage safety device
IPC: F16K25/00
Filed: 1980-11-28
Abstract: A shut-off valve has two valve flaps (6, 7) defining between them a leakage compartment (22) to collect any liquid leaking past either flap in the closed position. A drainage passage (26) is communicated with the leakage compartment (22), by way of drain ports (23, 24) when the flap valves are closed and sealed off, by blanking off the ports (28, 29) when the flap valves are opened. A flushing port (34) allows access of a flushing/cleansing fluid to the leakage compartment (22). Separate spring loaded valves (46, 47, Fig. 3 not shown) operated by cams (48), (49) may be provided to open and close the drain and flushing ports. Alternatively (Fig. 4, not shown) the drainage passage is opened when only one of the valve flaps is closed, to allow flushing by way of the pipe line rather than by way of a separate flushing port. In this case two drainage passages (opened and closed by respective spring loaded valves 46, 47) are provided. <IMAGE>

Title: Portable drilling or impacting device
IPC: B23Q9/00
Filed: 1981-02-27
Abstract: An implement for working on vertical surfaces consists of a stand (3) and a drive machine (1) for impact, drilling and like tools, mounted movably thereon. A bar (8), projecting from the stand, supports a dust extraction device (12) comprising a chamber (12A) with covers (14) on its lower side which, when the drive machine (1) is operating as a result of vacuum in the chamber (12A), are kept closed and thereby prevent the dust produced taking any path other than through an evacuation hose (15) which proceeds from the chamber (12A). When the implement is lifted away from the surface, atmospheric pressure prevails in the chamber (12A) and the covers (14) open. Chips, stones and other material which has collected in the chamber (12A) and which has not been evacuated through the hose (15) then drop to the ground.   <IMAGE>

Title: Coded information arrangement
IPC: B07C3/12
Filed: 1981-05-19
Abstract: An active transponder device comprises a CMOS integrated circuit including means (21) for receiving an input signal including coded information, a memory (31) for storing said information, and transmitter means (24) for transmitting an output signal including said information, the input signal and the output signal being both low frequency induction communication signals.Normally, the output signal is emitted in response to an interrogation signal received via the receiving means (21), and is formed by modulation of that signal with said information after readout from the memory. The transponder operates inherently synchronously, using a single master clock signal which is generated either in an interrogation transmitter or in the programmer for injecting the coded information.The integrated circuit has a second receiving means (41) used in the injection of the coded information. The injection of a clock-pulse which is in synchronism with the input signal enables the memory (31) to receive the coded information.The transponder may be used forthe identification of e.g. people or articles at the limits of a particular area e.g. a store.
