Title: Controllable oscillator
IPC: H03K3/0231
Filed: 1981-10-07
Abstract: The oscillator includes a comparator T3, T4 which controls the charging and discharging of a capacitor 1 in dependence upon the relationship between a signal representative of the state of charge of the capacitor and a reference signal at point 11. When T3, T5 are on capacitor 1 charges until the voltage at 3 falls below the reference voltage at 11, determined by resistor 10 and current source 12. T3, T5 then turn off and T4, T6 turn on to discharge capacitor 1. At the same time current mirror T14, T15 short circuits resistor 10 to raise the reference voltage to which capacitor 10 must discharge before the current reverts to its initial state. The invention is particularly useful in providing a temperature stable controllable oscillator. <IMAGE>

Title: Stable aqueous hydrogen peroxide solution
IPC: B22C1/22
Filed: 1981-10-27
Abstract: An aqueous hydrogen peroxide solution is stabilised by the presence of free fluoride (F<->) ions therein. Stabilisation may be achieved by addition to the hydrogen peroxide solution of a fluorine containing compound chosen from any fluorine derivative which, in the presence of water, hydrolyses to generate hydrofluoric acid, for example fluorine-containing acids such as hydrofluoric acid, fluosilicic acid and fluoboric acid, boron trifluoride, fluorine-containing salts such as the fluorides, fluosilicates, fluoborates and bifluorides. A reactant capable of oxidation by hydrogen peroxide can be oxidised by treating it with the above mentioned stable aqueous hydrogen peroxide solution at a pH of from 0.1 to 5.

Patent GB-2134963-A (GB)
Title: Latch with deadlock
Inventor: MOORE JEFFREY ALAN
IPC: E05B47/06
Filed: 1983-02-08
Abstract: A latch deadlock which from the outside can only be unlocked when a remotely controlled signal is sent to the deadlock, but which can be unlocked from the inside at any time. The lock mechanism is mounted in a door and a striker plate is mounted in a doorway, for example, so as to engage a bolt 3 when the door is locked. When the signal is sent a solenoid 14 moves via 15 a deadlock lever 4 out of engagement with the bolt 3, and by turning an outside handle at 12 the bolt can be withdrawn from the striker plate, so unlocking the door. When no signal is sent, the deadlock lever prevents movement of the bolt via the outside handle at 12. By turning an inside handle at 13, the deadlock lever 4 can be moved out of engagement and the bolt withdrawn, whether or not the signal is sent. A microswitch 16 can be used to detect the position of the bolt, to determine whether the lock is locked or unlocked. <IMAGE>

Patent GB-2123254-A (GB)
Title: Telephone instruments
Inventor: WILKINSON GRANT CAMERON
IPC: H04M1/27495
Filed: 1983-05-16
Abstract: A telephone instrument includes a microprocessor (10) preprogrammable from a keyboard (12) of the instrument with an authorisation level. The programmed authorisation level is used by the microprocessor (10) to determine whether a call to a telephone number "dialled" by use of the keyboard (12) is permitted. If a non-permitted number is dialled the microprocessor (10) causes a switch (19) to operate to disconnect the line (15,15%). Reprogramming of the authorisation level is prohibited until a key-operated switch (18) is closed. Repertory dialling facilities may also be provided by the microprocessor (10) in combination with a random-access- memory (R.A.M.) (11). Since calls to numbers held in the R.A.M. (11) are not subjected to prohibition, reprogramming of the repertory numbers is prevented unless either the key-operated switch (18) is closed or the preprogrammed authorisation level is such as to permit any outgoing call. In an alternative embodiment (not shown) a plurality of switches controlled by a key- operated lock are used to determine the authorisation level. <IMAGE>

Title: Endless belt conveyor systems
Inventor: COOK DENNIS LESLIE
IPC: B65G15/04
Filed: 1983-07-29
Abstract: An endless belt conveyor system has means for leading the belt (3) in its return run (3b) as roofing in proximity above a conveying run (3a) of the belt. The means (7b,11) supporting the belt serving as roofing may give it an arched configuration. Wall means (8) may close in the sides of the space between the two belt runs (3a, 3b) so that the material is conveyed in a closed passageway, which may be sealed by low-friction strips (7b, 9) on which edge regions of the two belt runs (3a, 3b) bear. At the loading region the two belt runs are spatially separated to accommodate feeding means which may comprise a continuously rotating transfer table, from which material falls onto the belt with a motion in the same direction as the belt. At the discharging region the belt runs are also spatially separated to accommodate receiving means which may comprise a continuously rotating table. <IMAGE>

Title: Reducing adherence of solder to gripping tools
Inventor: TRUSSLER GEOFFREY ARNOLD
IPC: C23C10/10
Filed: 1983-10-03
Abstract: A tool used for handling components during soldering operations has a pair of gripping elements between which the components are held. Each gripping element is of steel and has a layer of chromium carbide on its surface which in turn has a film of chromium oxide on its surface. The oxide film is not wetted by solder, thereby preventing adherence of solder to the tool. The oxide film also prevents material from the tool being dissolved in and contaminating the solder. The oxide film is formed by heating the steel gripping elements in an atmosphere of chromium chloride so that chromium diffuses into the steel to produce the layer of chromium carbide which forms an oxide film on its surface when exposed to air.

Title: Optical cables
Inventor: MATHER EDWARD LEWIS
IPC: G02B6/44
Filed: 1984-08-03
Abstract: To reduce migration of hydrogen into an optical fibre of an optical cable which might otherwise have a detrimental effect on the optical transmission efficiency of the optical fibre, the optical cable incorporates a material e.g. palladium wire, carbon fibres, phosphorus-loaded-glass which will readily absorb at least a substantial proportion of any hydrogen evolved within the optical cable whilst the cable is in store and/or is in service. Where the optical fibre (1) is loosely housed in a bore (2), preferably the hydrogen-absorbent material (4) is within the bore and may take the form of a "sacrificial" fibre of the hydrogen-absorbent material loosely housed in the bore. The optical fibre itself may have an overall coating of a hydrogen- absorbent material, e.g. palladium. <IMAGE>
