Title: Wind deflector with symmetrical geoometry
Inventor: WALWORTH VAN T
IPC: B60S1/38
Filed: 2008-02-06
Abstract: A resilient windshield wiper assembly is disclosed which comprises a resilient wind-deflector portion molded or extruded to provide a receiving hollow for insertion of a support beam. The resilient wind-deflector portion has a feature strategically positioned and structurally effective to prevent the resilient portion from being rotated or twisted around the support beam. The wind deflector is symmetrical with respect to the axial orientation of the support beam. The symmetry allows conversion of the wind force components from lifting forces to normal forces acting to press and/or hold the wiper against the wiper surface even when subjected to side gusts or reverse head-wind forces. The symmetry further provides a strength member acting directly over the top of the wiping lip surface avoiding introducing a twisting force into the support beam.

Title: A method of defrosting an evaporator in a beverage dispense system
Inventor: COOK CHRISTOPHER MICHAEL
IPC: B67D1/00
Filed: 2005-08-17
Abstract: A method of operating a cooler 6 comprises providing a refrigeration unit with an evaporator, positioning the evaporator in a bath of coolant comprising a mixture of water and an additive that suppresses the freezing point of water, operating the refrigeration unit to form an ice bank on the evaporator, defrosting the evaporator to return all the coolant to liquid form, and then re-operating the refrigeration unit to re-form the ice bank. The additive that suppresses the freezing point of water so that the ice bank has a temperature below 0{C may be e.g. glycol, alcohol or salt. The ice bank is regularly defrosted and reformed during periods when it is not required, for example overnight. This method of operation compensates for changes in the water/additive ratio when the ice bank is formed and thereby maintains the quality of the ice bank that is formed.

Title: Long fluxgate magnetometer
Inventor: BARTINGTON GEOFFERY WILLIAM
IPC: G01R33/04
Filed: 2008-06-12
Abstract: A fluxgate sensor comprises two ferromagnetic or ferrimagnetic cores (fig 1, 1,2) two sets of electrically conductive windings 5,6 wound around each core and an electrically conductive shield 7 enclosing the windings and cores. The windings 5,6 are connected to the shield 7 at one end 15 and carry a non-DC excitation current At the other end a sensor 22 detects a voltage between one of the windings and the shield, which can be proportional to the vector sum of the magnetic flux density along the fluxgate. The excitation current from generator 19 can be applied through the primary 20 and secondary windings of a transformer and a DC current can be applied via the secondary 21 to oppose the magnetic field to be measured. When an AC excitation current is used the impedance of resistors 23, 24, 25, 26 may be selected to enable the generation of standing electromagnetic waves along the fluxgate, and when a pulse excitation current is used resistors the impedances may be selected to enable an electromagnetic pulse to travel back and forth along the fluxgate, thus enabling spatial discrimination. The fluxgate may be flexible, in the form of a cable, and used to form a sensor several hundred metres long which may be arranged around a perimeter of a zone and used in an access control system, to sense the presence of vehicles for instance.

Title: Spark ignition systems
Inventor: PHILLIPS BRIAN LESLIE
IPC: F02P3/08
Filed: 1965-03-10
Abstract: 1,111,791. Ignition systems. JOSEPH LUCAS (INDUSTRIES) Ltd. March 3, 1966 [March 10, 1965], No.10109/65. Heading F1B. In a spark ignition system for an internalcombustion engine, energy derived from a battery is stored in an inductor 13 and then used to produce a spark, the amount of energy stored being determined by a saturable transformer 19 the primary winding 21 of which is fed with current at the same time as the inductor and which stops current flow from the battery to the inductor when the transformer saturates. When a spark is required a negative signal is applied by any convenient known means operated by the engine to the terminal 25. This signal turns the transistor 23 off and the transistor 22 on and the resultant e.m.f. induced in the winding 18 by current flowing in the winding 21 applies positive gate-cathode current to the switch 15 to turn it on whereupon the capacitor 28 discharges through the winding 29 and switch 15 to produce a spark. While the switch 15 is on current builds up in the winding 21 until the transformer saturates. At this point the voltage across the transistor 22 rises and the transistors 23, 22 are turned on and off respectively. The interruption in current in the winding 21 causes a negative gatecathode current to be applied to the switch 15 to turn it off. When the switch 15 is turned off energy stored in the inductor is employed to charge the capacitor 28 by way of the diode 14. A transistor can be used in place of the gate controlled switch 15. Temperature compensation may be provided either by the design of the saturating transformer or by the use of temperature-sensitive components in the circuit modifications are described.
