Title: Burial of wastes, eg. radio active waste
Inventor: BURTON WILLIAM ROBERT
IPC: G21F9/34
Filed: 1985-08-29
Abstract: Waste, for example radioactive waste, is buried on a single site. Waste 24 with organic but substantially no inorganic matter is in trench 23 and waste 22 with inorganic but substantially no organic matter is in trench 21. A water head H exists between the trenches (water level 26) and prevents flow of water from the organic waste to the inorganic waste. Each trench may have a surrounding ditch 29, 30 which can be filled with water to give a uniform water head round the trenches. Fig 1 (not shown) illustrates an embodiment where the water level is lower than the bottom of the waste trenches, and thus no liquid head is present to cause flow from the organic to the inorganic trench or vice-versa. <IMAGE>

Title: Gaming machines
Inventor: THOMAS ARTHUR EDWARD
IPC: G07F17/34
Filed: 1985-10-31
Abstract: A gaming machine (2) has a display (28) for displaying a plurality of sets (30, 32, 34) of symbols. The symbols are displayed in winning combinations, and a win is achieved by a player by the selection of all the symbols of a winning combination. The machine initially selects some of the symbols on a random or pseudo-random basis. The machine is capable of selecting at least two symbols from at least one of the sets. The player is allowed to perform a nudging operation whereby the or each selected symbol in a set chosen by the user ceases to be selected, and an adjacent symbol is selected instead. The game is an ancillary feature brought into operation on random or pseudo- random occasions during the playing of a sequence of main games using spinning reels (10). <IMAGE>

Title: Lowerable trailer suspension arrangement
Inventor: TOMECEK RICHARD LEE
IPC: B60P1/02
Filed: 1986-09-12
Abstract: This invention relates to a wheeled trailer comprising a load carrying body which is supported by wheels. In accordance with the invention such a trailer has at least one wheel on each of its lateral sides and there is provided jacking means which can be operated to lift the trailer relative to the ground to an upper position in which the wheels are clear of the ground. Each wheel of the trailer is connected to the body by a suspension system which permits limited relative movement in an up and down direction between the wheel and the body but which can be arranged when desired in an alternative inoperative configuration in which the associated wheel can move upwardly in its own plane relative to the body. Each of said suspension systems incorporates a leaf spring which is connected at one end to a member which is pivotable relative to the body and which is free at its other end so as to be engageable in its operative position with a moveably mounted abutment and said abutment is removeable from the trailer or moveable to an inoperative position in which it is not engaged by the free end of said leaf spring. (Jacks not shown in Fig. 1). <IMAGE>
Patent GB-2181571-A (GB)
Title: Strip material winding
Inventor: BOOTAN ALAN JOHN
IPC: B65H59/38
Filed: 1986-10-01
Abstract: In the winding of strip material the passage of the material (1) is monitored by passing the material in sufficiently close proximity to a vibratable member (2), e.g. a wire, as to set the member into vibration. The occurrence of the vibration is detected by a detector (3) such as a piezoelectric crystal and the resulting electrical signal is used to control the rate at which the strip material is wound at 12. In the arrangement shown there are two detectors (3) at different levels. When the material lifts away from the wire (2A) connected to the upper detector the winding is stopped, but when the material contacts the lower wire (2B) the speed of winding is increased. The technique may be used to wind optical fibres in a tension free manner. <IMAGE>

Title: Decoding transmitted scrambled signals in a pay television system
Inventor: CROWTHER GERALD OFFLEY
IPC: H04N7/167
Filed: 1986-10-24
Abstract: In a pay television system a programme signal is transmitted scrambled to prevent its un-authorised reception, the scrambled signal being accompanied by authorisation codes, one for each authorised subscriber, a subscription key and a pay-per-view key.

If the appropriate authorisation code is not received indicating that the subscriber is not pre-authorised to receive the programme in an inelligible manner, the receiver is set to function in a pay-per-view mode in which mode, on request, the pay-per-view key provides for the descrambling of the programme signal. Details of message packets and the encryption are disclosed.

Title: Termination of mineral insulated electric cable
Inventor: POSTILL ALAN
IPC: H02G15/04
Filed: 1987-06-17
Abstract: In a simple method of terminating a mineral insulated electric cable 1, hardenable bonding material 8 in a semi-liquid state is applied to the end face of the cut- back end of the cable and a preformed cap 6 comprising an end wall and a circumferentially continuous peripheral wall is slid on to the bare lengths of conductor 2, the end wall being of electrically insulating material and having an aperture for each conductor. The cap 6 is slid along the bare lengths of conductor 2 towards the cut-back end of the cable 1 and is urged against the end face of the cable to cause bonding material 8 to flow into and fill the space between each length of conductor and the boundary wall of the aperture in the end wall through which it passes. The peripheral wall of the cap 6 is sealed to the underlying cable sheath, e.g. by the bonding material, and the bonding material is then permitted or caused to set. Prior to sliding the cap onto the conductors, a preformed disc of electrically insulating material can be slid over the conductors. <IMAGE>

Title: Welding current control apparatus
Inventor: MEDINE CALUM EDWARD
IPC: B23K9/10
Filed: 1989-06-19
Abstract: The apparatus comprises a welding plant 1, an arc starter unit 2 and a remote unit 4 controlled by switches 10, 11 on a welding torch 3. At the commencement of a welding operation the operator presses switch 10 which turns on the welding arc. Then, maintaining pressure on switch 10, switch 11 is pressed which operates a motor 9 to adjust a variable resistor 7 to increase the welding current. On releasing switch 11, but still maintaining pressure on switch 10, the welding current maintains a steady level. To decrease the current level, switch 10 is released, which reverses the motor 9, and the switch 10 is then repressed to maintain the current at a lower level. If the switch 10 is maintained released the current level gradually decreases to zero, and the welding arc is switched off in response to opening of a limit switch 8. <IMAGE>
