Title: Drainage of highways
Inventor: WILLIAMS LESLIE RICHARD
IPC: E01C11/22
Filed: 1982-09-14
Abstract: In a kerb drain comprising abutting precast concrete channel sections (10) covered by apertured kerb blocks (24) the sections (10) are of different channel sizes along different stretches of road, according to the amount of water expected, and are connected, at a change of size, by a precast tapered-channel section (34) forming a connector unit. So that the kerb can be straight throughout a continuous run of drainage channel including such a connector unit, the various parts of the tapering flow channel of the connector unit all merge gradually by means of respective planar surfaces extending from one end of the unit to the other, but the vertical side wall (12) which is to be located adjacent the carriageway is arranged in a plane perpendicular to the respective end surfaces (36, 38) of the unit. <IMAGE>

Title: Method of forming a hydrophilic coating on a substrate
Inventor: WINN R ALISTAIR
IPC: C08J7/056
Filed: 1982-10-14
Abstract: A method of forming a hydrophlic coating on a substrate comprised of applying a hydrophilic copolymer capable of chemically reacting with a coupling agent which will promote adhesion to the substrate.

Patent GB-2107904-A (GB)
Title: Controlling kilns
Inventor: ROTHE UWE
IPC: H05B3/00
Filed: 1982-10-18
Abstract: Disturbances resulting from differences in the throughput of ceramic material to tunnel kilns are assessed in advance to pre-optimise firing conditions in the kiln. The detection of the parameters determining the firing process is effected by interrogating the transport means at any point in its travel and follows from the total mass less the tare mass subjected to the firing and from the geometry of the superstructure of the transport means. The information obtained is fed to a store in a computer system and called up for use in further data processing whereby the firing conditions at fixed points in the kiln are pre-optimised. The interrogation is effected by an identification unit comprising a stationary transmitter-receiver and a codable reflector, which is mounted on the guard plate of the transport means.

Title: Milk cooler
Inventor: JONES ROBERT REES STEPHEN
IPC: A01J9/04
Filed: 1982-09-30
Abstract: This invention relates to milk coolers and comprises a container 18 into which is fitted a cooling coil 20. The container has a milk inlet 12 and an outlet 15A, the latter of which is connected to a source of vacuum.

Title: Mobile drilling rig
Inventor: BALL PETER DAVID
IPC: E21B7/02
Filed: 1983-03-01
Abstract: The drilling rig, which is particularly suited for use in developing countries, has a support structure, e.g. a chassis (10), and a mast which is pivoted to the chassis so that it can be lowered during transportation. An elongate drive member (27) is supported by a wire (25) which is connected over a sheave (30) to a winch (28.) A drilling device e.g. a drill bit or auger can be attached to the drive member (27). A rotary drive device (32) for rotating the elongate drive member is to all intents and purposes permanently mounted on the elongate drive member. When a drilling operation is to be performed, the rotary drive device can be releasably coupled to the drive shaft therefor and releasably fastened to the chassis. However, it can be uncoupled and unfastened readily in order that it can be swung as one unit with the elongate drive member away from the centre line of a hole being drilled in order to remove spoil from an auger attached to the elongate drive member or to allow a casing to be lowered into the hole. <IMAGE>

Title: Dual purpose caps for fretted instruments
Inventor: SCOTT IAN DONALD
IPC: G10D3/04
Filed: 1983-03-24
Abstract: A capo for fretted instruments, e.g. guitars, uses a set of cylinders so as to effect not only alterations of pitch but also of the absolute relations between the strings. A U-shaped frame holds a movable steel rod which permits of adjustment to instruments of different dimensions by means of a racked channel. The frame is secured to the neck of the instrument by the force exerted in the direction of the rod bye spring mechanism. A cylinder with a hole drilled off-centre is slid onto the rod before the frame is secured to the instrument. The cylinder has two surfaces, one plane and the other slotted, so that alterations to pitch and tuning can be effected. The slotted surface of each cylinder has a different configuration of slots, creating different patterns of stopping on the strings. The selected cylinder is one of a set so designed as to yield all possible configurations. <IMAGE>

Title: Optical fibre splicing
Inventor: STANNARD-POWELL SIMON JOHN
IPC: B29C65/70
Filed: 1983-12-21
Abstract: In a method of covering a fusion splice 1 between optical fibres 2 having a cladding 3 of hardened resin, semi-fluid resin 5 is applied to one surface of a length of tape 6 and the tape is folded around the optical fibre splice so as to form a mould cavity 8. The volume of the mold cavity 8 is reduced by continuously squeezing the overlying end parts 7 of the tape 6 together e.g. by drawing through a die 9 to ensure that the mould cavity 8 is filled with resin 5. The resin 5 is caused or permitted to set and bond to the exposed parts of the fibres 2 and to the cutback ends of the claddings 3. After the resin 5 has set, the tape 6 is peeled away. <IMAGE>
Patent GB-2154816-A (GB)
Title: Electrical heating circuits
Inventor: WALKER ROBERT HOLLIS
IPC: H02H5/04
Filed: 1984-02-21
Abstract: A heating conductor 14 for an electric blanket is wound concentrically with a sensing conductor 22 but separated from it by a temperature-sensitive insulating layer 28 and is fed from the a.c. supply via a bridge rectifier 32 to 38. In the event of local or general overheat, the insulation of the layer 28 drops significantly, so that current now flows through resistor 20 and the resulting heat trips a thermal switch 16. The bridge rectifier ensures that sufficient current will flow through resistor 20 even with a local overheat close to one end of the blanket. <IMAGE>

Title: Hydropneumatic cable tensioner
Inventor: JORDAN LARRY B
IPC: F16F9/06
Filed: 1986-07-18
Abstract: A hydropneumatic cable tensioner is comprised of an enclosed cylinder C featuring a plurality of annular chambers. A fixed cable sheave is mounted to one end 40 of the cylinder. A movable cable sheave is mounted to a piston rod R connected to a piston P which reciprocates in a piston bore chamber K of the cylinder. Regulated compressed gas is connected at 70 to an outer accumulator chamber A of the cylinder thereby exerting high pressure forces on oil found in the middle chamber K of the cylinder. Pressurized oil forces the piston P to move outwardly thereby increasing the distance between the two sheaves and tensioning a cable. A containment chamber E within the piston rod holds an initial charge of gas. Restriction ports 120 between the piston bore chamber K and the containment chamber E regulate movement of the piston and prevent uncontrolled acceleration should a cable failure occur. Ejection of the piston rod is prevented by providing the piston P with a frusto-conical bushing 150 which can cooperate with an annular ring 180 fitted at the end of piston bore chamber K. <IMAGE>
