Patent GB-2240980-A (GB)
Title: Process of forming joints in vulcanised rubber articles
Inventor: KAUZLARICH JAMES J
IPC: C08J5/12
Filed: 1991-01-22
Abstract: A process for forming a joint between a post-vulcanized rubber article and itself or between a post-vulcanized rubber article and another article comprises placing a bonding material, e.g. an adhesive or uncured rubber, between the parts of the article(s) to be joined, heating the bonding material under compression to effect curing thereof and thereby form the joint and releasing the joint from compression; in the process of the present invention, the bonding material is microwave absorbent, the parts of the article(s) on either side of the joint absorb microwaves to a lesser extent than the bonding material and the heating of the joint is performed by microwave heating. The curing of the joint by microwave heating decreases the cure time and prevents the article(s) from being over-cured or reverted. The bonding material may incorporate a microwave absorbent additive, e.g. certain carbon blocks, PbO2, BaTiO3, BaSO4 or ZnO.
Patent GB-2241451-A (GB)
Title: Adhesive bonded abrasive finishing tool
Inventor: TYLER JAMES B
IPC: B24D13/16
Filed: 1991-01-28
Abstract: A rotary finishing tool includes at least one rolled or coiled strap 102, 152 of plastic material with abrasive homogeneously embedded throughout. The coiled strap is secured to the bottom interior surface of a cup element 104, 154 by a thin layer of liquid quick setting or instant adhesive 106, 156. The strap may include transverse slits 108 or serrations to provide the degree of flexure desired and/or to provide fracture lines. To make the tool, a longitudinally extending strap of an abrasive containing plastic material is heated and rolled along its longitudinal axis thereby forming a lightly coiled strap. A cup element is supported and the coiled strap is driven into the cup element whereby one end face of the coiled strap is driven into contact with a thin layer of the instant adhesive. Upon curing of the adhesive, the one end face is secured to the bottom interior surface of the cup element, and the opposite or outer end face becomes the working face of the tool. <IMAGE>

Title: Antibodies binding to stratum corneum of the epidermis
Inventor: REICHERT UWE
IPC: A61K47/48
Filed: 1991-02-07
Abstract: Polyclonal and monoclonal antibodies bind to the stratum corneum of the epidermis, which may or may not be affected by keratinization disorders such as icthyosis, photo-induced cutaneous aging, psoriasis and eczema. The epidermis can be of human and non-human origin. The antibodies can also recognise human keratinized epithelial tissue. The production of such antibodies, the application of such antibodies as drug vectors and as markers to detect terminal differentiation of the epidermis is disclosed.

Title: Current control device for electromagnetic clutch
Inventor: MIMURA MUNEHIKO
IPC: H02M3/158
Filed: 1991-02-07
Abstract: A current control device for an automotive electromagnetic clutch includes first and second transistors 8 and 13 and a current detector resistor 14, which are coupled in series with the clutch 4. A PWM modulator 7 controls the ON/OFF of the transistor 8 to control the excitation current flowing through the clutch. The transistor 13 turns off the excitation current in response to the disconnection signal SO for the clutch. A current detector 6 detects the current flowing through the resistor 14, and the amount of current through the clutch is controlled to a target value via a calculation device 2, a deviation amplifier 5, and the PWM modulator 7. The error in current detection owing to the current flowing through a reverse excitation resistor 12 may be eliminated by the insertion of a transistor 17 controlled in response to the clutch disconnection signal SO by a transistor 19, Fig. 2. Alternatively the effect of the base current on the current detection may be eliminated by using as the second transistor a transistor (70) of the field effect type (Fig. 3). <IMAGE>
Patent GB-2246688-A (GB)
Title: Audio communications systems
Inventor: SMITH PETER LEIGHTON
IPC: G10L25/78
Filed: 1991-05-08
Abstract: An electrical circuit, for use in a headset communications system for wear in an environment with a high level of background noise, has an attenuator 5 which receives a combined noise and speech input signal 1 and a monitor 6 which monitors the input signal and controls operation of the attenuator. When no speech input is detected, and the noise input at least exceeds a pre-set level, the input signal is attenuated by between about 10 to 20 dB to prevent a high noise level in the output signal, yet still allow the headset wearers to be aware of the environment surrounding the circuit's input microphone(s). A low noise inhibit circuit 12 inhibits the attenuator when little or no background noise is present. The attenuation varies with input frequency, being generally constant at lower noise frequencies and increasing at higher noise frequencies to compensate for the fall-off in performance of noise cancelling microphones above 1KHz. <IMAGE>

Title: Vehicle handling attachment
Inventor: BLAND DAVID WILLIAM
IPC: B66F9/18
Filed: 1991-09-19
Abstract: A vehicle handling attachment is provided for use for handling and manoeuvre of vehicles. The unit is slid onto fork truck tines at (A). When driven beneath a vehicle from front or rear, tyre forks (c) come into contact with the vehicles tyres. The forks start to hinge open in a horizontal plane around the tyres stopping at position (C1). Now the attachment may be raised clear of the ground to manoeuvre the vehicle. Steering is achieved by means of a cross head (b) swivelling on bearings mounted in main body (A) and centralised by means of extension springs and cables mounted within the main body. Once the manoeuvre is completed the attachment is lowered and slowly reversed from beneath the vehicle during which the springs mounted in the main head (B) and attached to the tyre forks (C) return both of the forks to the closed position. <IMAGE>

Title: Constant energy feed system to the shaft of a synchronous dynamoelectric machine; standby power supply
Inventor: LOPEZ JIMENEZ MIGUEL
IPC: F02B3/06
Filed: 1992-11-18
Abstract: An electricity supply network 4 normally energises a load 2 and is also connected to a synchronous dynamoelectric machine 1. On detection of failure of the network 4, a hydraulic engine 3 maintains rotation of the machine 1, now acting as a generator to supply load 2, and the hydraulic engine 3 also starts a diesel engine 5 which then drives the machine 1. Engine 3 is connected in a hydraulic circuit 14 including a pump 6 pressure accumulator 8, and a valve 11 controlled by an electronic system 9 responsive to a speed sensor 10. If the electronic system 9 fails the hydraulic system can control the speed of machine 1 but the maximum speed variation may then be higher. <IMAGE>

Title: Filtration apparatus and method
Inventor: CANTWELL ALAN DAVID COLE
IPC: B01D24/46
Filed: 1992-11-19
Abstract: Filtration apparatus comprises a column (1) having a lower liquid inlet (7), an upper liquid outlet (2), and an intermediate internal screen (4) adapted to confine a bed (5) of buoyant particles therebelow; means (8) adapted to cause liquid to flow up the column; and means (9, 10) adapted to expand the bed. Such apparatus can be used to remove biodegradable impurities from a liquid, by causing the liquid to flow up the column, the column including, below the or each screen, buoyant particles on which biomass will collect; and intermittently operating the expansion means. For example, an aeration pump may be operated such that, in normal flow conditions, the bed is substantially undisturbed, and intermittently such that the particles are less buoyant and biomass on the particles is removed by attrition as the particles circulate.

Title: Mechanism for connecting and disconnecting tubulars
Inventor: STOKKA ARNOLD
IPC: E21B19/16
Filed: 1996-07-31
Abstract: A top drive is used to connect successive lengths of casing. The casing is gripped by a mechanism 100 which comprises a support 5 which is attached to the top drive by a drive plate 4. A circular plate 9 is rotatably mounted in the support 5 and is associated with four jaw assemblies 50. In use the mechanism 100 is lowered onto a length of casing until the circular plate 9 engages the top of the casing. When the top drive is rotated in one sense the support 5 rotates relative to the circular plate 9. This causes toothed cylinders 14 to rotate which, in turn, rotates eccentric members 12 and 13 which advance the jaws 15 into gripping engagement with the casing. Further rotation of the top drive rotates the casing and screws it into the casing below.
