IPC: G07F11/42
Filed: 1989-03-13
Abstract: A vending machine has a chamber therein divided by a divider 17 into a product dispensing section and an air passageway section 16. The refrigeration system includes an integral housing so that the refrigeration unit as a whole can be quickly installed or removed. One portion the refrigeration system which includes a compressor 29 and condenser 31 is disposed in but isolated from the lower portion of a product dispensing section and includes an inlet 54, 55 for ambient air, an outlet 56 for ambient air, and a circulation system including a fan 32 for causing air to pass from the inlet to the outlet thereof. An evaporator portion of the refrigeration system is disposed in the air passageway 16 and to one side of the divider 17, an air inlet 40 in the bottom of the divider 17 allowing air from the product dispensing section to pass through the evaporator 34. An air outlet 59 in the top of the divider 17 allows air, which is forced by fans 37 in the air passageway 16 to exhaust cool air into the top of the product dispensing section of the vending machine, thereby causing good circulation of the air through the product dispensing section. <IMAGE>

Title: Control of liquid crystal display visual properties
Inventor: EATON TIMOTHY JOHN
IPC: G09G3/36
Filed: 1989-10-27
Abstract: The contrast or absolute brightness of a multiplexed LCD is maintained at its preselected value using a feedback arrangement which includes an LCD element functioning as a reference element. The reference element is not used to display information but is continually driven ON and OFF. The average transmissivity of the ON and OFF states is determined and compared with a reference value, the result of the comparison being used to control the voltage levels of the drive waveforms applied to the LCD. By selecting appropriate ratios between the ON and OFF times of the reference element, the LCD can be operated to give optimum contrast, or may have its absolute brightness varied. Control may be effected remotely by reprogramming the microprocessor which determines the timing of the drive waveforms.

Abstract: PCT No. PCT/GB90/00419 Sec. 371 Date Aug. 20, 1991 Sec. 102(e) Date Aug. 20, 1991 PCT Filed Mar. 20, 1990 PCT Pub. No. WO90/11540 PCT Pub. Date Oct. 4, 1990.Six secondary optical fibres (20) are located about and parallel to a central optical fibre (21) by a capillary tube (22) to form a fibre bundle which is then formed into a fused, tapered coupler in which the tapering is stopped when the proportions of light coupled out of the central fibre (21) at 1.3 and 1.53  mu m are first equal. The fusion process can provide sufficient fusion between the central fibre and each secondary fibre to provide a 1 to (n+1) coupler where n is the number of secondary fibres. This method provides a coupler which is wavelength-flattened between 1.3 and 1.53 mu m using similar fibres.

Title: Cleaning the metal surface of a component by circulating aqueous soda and then washing with water
Inventor: GARCIN ISABELLE
IPC: C23G1/14
Filed: 1992-10-23
Abstract: A process for cleaning the metal surface of an installation component which has been used for the treatment of organic effluents, particularly organic effluent evaporators is characterised by circulation (by pipes 9, 13 and 11) on the inner surface of component (eg tubes (3) thereof) of an aqueous soda solution containing 4 to 11 mole/1 of NaOH, at ambient temperature and then rinsing with water is carried out. Preferably, the soda solution contains a wetting agent, e.g. an equimolar quantity of dibutyl phosphate and monobutyl phosphate and at least 15 hours elapse before rinsing with water is performed in order that the soda which has impregnated the deposits to be eliminated has time to convert them into water-soluble products. in one embodiment circulation of the soda solution takes place for approximately 5 min, followed by a 24 hour wait, and then water rinsing takes place for approximately 30 secs. <IMAGE>

IPC: B60R16/02
Filed: 1993-04-28
Abstract: A multiplexed data transmission system for use in a motor vehicle comprises a central control means 1 linked by data bus 2 to a plurality of control nodes 3 distributed around the vehicle, each control node being operatively linked to at least one adjacent switch means adapted to control the electrical power supply to a local electrical power-consuming component 4 and further adapted to break the supply of power to said component if the current exceeds a pre-determined value, whereby control data supplied by the central control means is transmitted to a selected control node via the data bus and subsequently brings about the switching of selected switch means and thus the selective operation of an associated power-consuming component. Monitoring means remains dormant while receiving a regular monitoring signal from the central control means 1, and sends switching signals to the switch means in response to cessation of the monitoring signal for a pre-determined time. <IMAGE>

Title: A system for controlling the charging of an internal combustion engine
Inventor: BAEUERLE MICHAEL
IPC: F02D41/00
Filed: 1993-06-16
Abstract: A variable characterising the charging of an internal combustion engine (100) is controlled by means of a closed servo loop. In order to optimise the control, the transfer behaviour of the controller (136) is influenced by the rotational speed (n) of the internal combustion engine and an operating parameter (g), which characterises the output dynamics of the internal combustion engine (100) and the charging device (106, 114, 116). In the case of large control deviations (e), the operating parameter (g) is derived from the actual value (y) of the controlled variable. By virtue of raising the value of the operating parameter (g) when deactivating the control, it is possible to avoid the operating parameter (g) being determined incorrectly when the control is reactivated immediately afterwards. In the case of small control deviations (e), a steady-state operating condition is used as a basis and an empirical value is used for the operating parameter (g). <IMAGE>
