Title: Amperometric gas sensor
Inventor: KESSEL ROBERT
IPC: G01N27/49
Filed: 1995-07-13
Abstract: An amperometric sensor for the detection of acidic and basic gases using a first pH-dependent reversible redox system at a working electrode 4, with the reduction current which occurs between the working electrode 4 and a counter electrode 6 with applied constant potential, being a measure of the concentration of the gas which is to be detected. A reference electrode 5, the working electrode 4 and the counter electrode 6 are located in an electrolyte 7, in which gas to be detected which has passed through permeable membrane 2 is dissolved with dissociation. To improve continuous stability, the first pH-dependent redox system is coupled with a second redox system, and the redox potential of the second redox system is chosen such that the reaction product which is formed electrochemically by the first redox system is chemically regenerated by the second redox system to form the educt again. As described, a carbon dioxide sensor has a first redox system of iridium dioxide, and a second redox system of potassium iodate, the latter being dissolved in lithium chloride electrolyte. <IMAGE>

Title: Wall ventilator
Inventor: IRWIN ROGER GEORGE
IPC: F24F7/04
Filed: 1996-07-11
Abstract: The present invention relates to a wall ventilator, that is to say a device for establishing a ventilation passage through the wall of a building. The wall ventilator of the present invention comprises a lining (1) for insertion into an aperture formed in a wall from the internal surface of the wall; a grill or louvre (2) secured to the distal end of the lining (1) for passage through the aperture to a location substantially flush with the external surface of the wall; and an internal grill or louvre (3) securable to the lining (1) and to the internal surface of the wall so as to maintain the wall ventilator in an operative position. The wall ventilator of the present invention may be therefore located in an operative position without the need to access the external surface of a wall, and consequently, is more convenient to install than prior art wall ventilators.

Title: Communicating messages asynchronously
Inventor: PRILL MARK
IPC: H04L12/403
Filed: 1996-08-05
Abstract: A data-transmission system (100) includes a master device (101) and at least one slave device (105) and communicates messages having an address and data from the slave device (105) to the master device (101). The address is communicated synchronously and the data is communicated asynchronously. Furthermore, the address determines the control information and timing signal transmitted by the master device (101) to the slave devices (105-N). Application is to radio telephones. The slave devices have pre-determined priority in their addresses, with asynchronous addresses having priority over synchronous addresses, and can initiate communication with the master device.

The contact faces 54,58 of the mortise and tenon are angled relative to a radial plane of the disc so that centrifugally generated forces are reacted by the faces in a sense to counter axial tilt so that the seal face 38 of the plate lies exactly in a radial plane, at a design rotational speed, thereby to eliminate convergence or divergence between the seal faces 36,38 of the air riding seal.
Patent GB-964592-A (GB)
IPC: F01D9/04
Abstract: 964,592. Making blade rings; welding by fusion. SOC. RATEAU. Feb. 27, 1961 [Feb. 20, 1960], No. 7149/61. Headings B3A and B3R. [Also in Division F1] The blades of a turbine stator ring are welded to the supporting rings by continuous circular welds and subsequently the assembly is divided, e.g. by sawing into two half rings. The blades t are assembled to form a ring comprising two half rings, each of more than a semi-circle and centred on points O<SP>1</SP>, O<SP>11</SP> spaced by a distance equal to the width e of the saw cut to be made. The inner and outer faces R 1 , R 2  of the ring of blades are machined on a lathe about a centre O mid-way between the centres O<SP>1</SP>, O<SP>11</SP> to form surfaces d 1 , d 2  of welding grooves S 1 , S 2 . The supporting rings f, c are also machined so that when assembled with the blade ring they form complete grooves S 1 , S 2 . The half blades at the ends of the half rings are formed as shown in Fig. 7, or alternatively the part to be cut away may be left solid. The welding is effected by continuous passes going completely round the ring. The grooves may be cut as shown at S 1 , Fig. 6, of sufficient depth to enable complete penetration to be achieved. Alternatively, one deep groove S 2  may be cut and welded prior to a second deep overlapping groove being cut and welded.

Title: Inductive coin validation system
Inventor: CHURCHMAN JAMES
IPC: H04M17/00
Filed: 1997-11-19
Abstract: A coin validation arrangement, usable for example in pay telephones, uses one or more inductive sensors 17 having a small effective magnetic field so that the inductive sensor 17 responds only to the material of a strip across the coin. Preferably a plurality of inductive sensors 17 are used, mounted at different heights above the floor of the coin guide, at different positions along the coin path. At each position along the coin path there may be either one or a plurality of inductive sensors 17.

Title: Wiper motor overload protection
Inventor: KESSLER MARTIN
IPC: H02H6/00
Filed: 1998-01-27
Abstract: A control device, for operating a wiper motor (10), which device employs the typical curve of the wiper motor current (Im) with cyclically recurring minima in identifying overloading of the wiper motor (10) produced by jamming or sluggishness of the wipers. When an overload occurs, above a threshold value (S1), circuits 24 and 28 allow a storage element (C) to charge. Under these circumstances, the storage element (C) integrating the motor current (Im) is short-circuited via a switch 18 at least twice within one wiping cycle (Tw) in normal operation, so that the transfer of the admissible overload from one half of the wiping cycle (Tw/2) to the following half of the wiping cycle (Tw/2) is prevented and the limiting value (G) for switching off the wiper motor (10) is not reached as a result of accumulation of the admissible overload.
