Title: Locking differential with sacrificial tube that prevents component failure
Inventor: MASON KEVIN ANDREW
IPC: F16H48/30
Filed: 2008-06-23
Abstract: A locking differential, for a vehicle, has a locking arrangement 27 comprising a locking collar 28 which slides on half shaft 24 to an operative position (fig 3) where it engages a differential housing 14 so that the half shaft 24 rotates with the housing 14 which, in turn means that half shaft 23 rotates with the half shaft 24, thereby driving road wheels 25, 26 in unison. The locking collar 28 is provided with a groove 38 a depth of which establishes a predetermined load at which a sacrificial tube 34 will fail thereby unlocking the locking differential. If the vehicle becomes stuck in mud and an undue torque is applied to input shaft 11 while the locking collar 28 is in its locking position the sacrificial tube 34 will fail at the groove 38 and the differential will ceased to be locked.

Title: Thermostatic radiator valve
Inventor: MANNING THOMAS
IPC: F24D18/00
Filed: 2008-07-11
Abstract: A thermostatic radiator valve 10 fitted to a radiator 2 comprises a valve member 11, a valve driving means and a temperature sensor. The valve driving means moves the valve member 11 between fully open and fully closed positions in response to the zone temperature. The valve driving means is operated when the zone temperature rises above a first threshold temperature to fully close the valve member 11, the first threshold temperature being lower than a preset target temperature for the zone to be heated. If the zone temperature subsequently drops below a second predetermined threshold temperature, normal operation of the valve 10 is resumed. In a further embodiment, a heating system (100, Figs. 3, 4) powered by a boiler 30 can be controlled in response to the position of valve 10. The system 100 may shut down boiler 30 when a first specified number of valves 10 are closed and may restart operation of boiler 30 once a second specified number of valves have reverted to normal operation.

Title: Method of Testing a Pipeline Cut
Inventor: BANKS STEVE
IPC: E21B47/12
Filed: 2008-09-26
Abstract: A method of testing the through cut 14 of a pipeline 10 comprises at least the steps of transmitting an electromagnetic signal 32a, 32b, along the pipeline and interpreting received signal(s) to test for the through cut of the pipeline. In this way, a non-invasive signal can be passed along the pipeline and the reflected signals can be interpreted and analysed based on one or more characteristics of the received signals to ascertain the change in the conductivity of the pipeline due to the cutting thereof, in particular when or whether the cutting of the pipeline is complete. The method is particularly suitable where access to the location of the cut of the pipeline is difficult or not accessible. Such pipelines include underwater, below seabed or below the mud line pipelines and may be hydrocarbon conductors such as oil drilling conductors. Cutting and removal of pipelines is required for decommissioning of offshore platforms.

Title: Overcurrent control system for an electric machine
Inventor: MARVELLY JOHN DUNSTAN
IPC: H02P6/00
Filed: 2009-04-04
Abstract: A control system for an electric machine comprises a current controller 15 and a drive controller. The current controller comprises an input, an output, a comparator 25 and a latch 26. The comparator 25 sets the latch 26 when a voltage at the input, from a current sensor, exceeds a threshold, and the latch 26 outputs an overcurrent signal when set. The drive controller then resets the latch after a predetermined period of time. The current controller may also output an interrupt signal to the drive controller, which may then execute an overcurrent routine by causing the switches of an inverter to freewheel. The current controller is suitable for an electric motor for a vacuum cleaner.

Title: Esters of drying oil acids with certain vinyl polymers
Inventor: RINGWALD RICHARD MICHAEL
IPC: C09D133/06
Filed: 1954-04-07
Abstract: Glycidyl acrylate or methacrylate is esterified with a drying oil acid, such as those derived from linseed, sunflower seed, tobacco seed, soya bean, dehydrated castor, marine animal and tung oils.  In an Example (4) glycidyl methacrylate is esterified with linseed oil acids in solution in xylol in the presence of benzyl trimethylammonium hydroxide as a catalyst and a trace of hydroquinone.  Specification 767,476, [Group IV (a)], is referred to.ALSO:An ester is formed from a drying oil acid, e.g. one derived from linseed, sunflower seed, tobacco seed, soya bean, dehydrated castor, marine animal and tung oils, and a copolymer of glycidyl acrylate or methacrylate and at least one other polymerizable vinyl or vinylidene compound, e.g. methyl, ethyl, nonyl, lauryl, beta-ethoxyethyl and cyclohexyl acrylates and methacrylates, acrylonitrile, methacrylonitrile, vinyl toluene, vinyl acetate and vinyl chloride.  The ester may be formed either by esterifying the glycidyl ester with the drying oil acid and then copolymerizing with the unsaturated monomer, or by esterifying a preformed copolymer with the drying oil acid.  The copolymers may be prepared by heating the monomers in solution in xylol in the presence of a catalyst such as benzoyl or ditertiary butyl peroxide, tertiary butyl hydroperoxide, tertiary butyl perbenzoate and diazobutyronitrile; in one exemplified method of copolymerization a mixture of methyl and nonyl methacrylates is added gradually to a refluxing solution of glycidyl methacrylate. The esterification of the copolymer with the drying oil acid is carried out in the presence of esterification catalysts such as benzyl trimethyl ammonium hydroxide, litharge and caustic soda. The products yield films which dry on exposure to air.  The Provisional Specification describes also the use of styrene as a monomer which may be copolymerized with the glycidyl acrylate or methacrylate.  Specification 767,476 is referred to.

Abstract: 1,092,934. Automatic volume control. BRITISH TELECOMMUNICATIONS RESEARCH Ltd. March 7, 1966 [March 10, 1965], No. 10218/65. Heading H4R. In an automatic volume control employing thermistors as the gain controlling variable element a number of thermistors are provided in association with the control network with arrangements for readily connecting them in different arrangements in order to provide preset gain adjustment while still maintaining the same sensitivity of control. Fig. 3 shows an arrangement of two thermistors associated with a gain regulating network AGR, the attenuation of the network being controlled by the resistance presented by the thermistors to the network which depends on the manner of their interconnection and the control current D.C. flowing therethrough. Preset adjustment of the resistance presented by the thermistors is provided by suitable interconnection of the terminal shown, the dashed connection placing the thermistors in series, the circle-dashed connection placing only one thermistor in circuit while the cross-dashed connection places the thermistors in parallel for A.C. signals relative to AGR, though still in series with respect to the D.C. control current. The D.C. control current may be derived from a pilot signal.

Title: Improved photographic film camera
IPC: G03B19/04
Filed: 1927-04-14
Abstract: 286,491. Reiterer, R., and Hofmann, J. C. April 14, 1927. Cameras, reflex.-A roll-film casing with a focal plane shutter 9, Fig. 1, is mounted on the top of the camera and the film 11 is exposed by reaction from a mirror 1 which is adapted to be moved down from a horizontal inoperative position to an angle of 45‹. The image is focused on a rear screen 12. The mirror is normally raised to the inoperative position by a spring 3, Fig. 2, on the shaft 2. It is moved down for exposure by an outside projecting finger-piece 6 on an angle-lever 4, 7, which is freely mounted on the shaft 2. The lever 4, 7 turns the shaft 2 by a spring 5 and lever 17, the spring 5 being stronger than the spring 3. When the mirror comes against a frame at an angle of 45‹, further action on the projection 6 causes the arm 7 to engage a pin 8 and release the shutter. After releasing the projection 6, the mirror returns to its inoperative position and the lever 4, 7 over-shoots its normal position, the arm 7 releasing a spring arm 16 holding a spring wheel 14 which now rotates the film winding spool 10 until arrested again by the arm 16.
