An antenna arrangement comprises a patch conductor (102) having a feed conductor (106) connected to a first point and a grounding conductor (108) connected between a second point and a ground plane (104). An example of such an arrangement is a conventional planar inverted-F antenna. A problem with such antennas is that their impedance is inductive, making them difficult to feed. The present invention incorporates a slot (702) in the patch conductor (102) between the first and second points, whic...

An antenna arrangement comprises a folded structure (100) comprising first and second sections (102, 104) defining a transmission line. The sections may be meander-line elements or other physically-shortened electric elements, for example a helical element. Respective feed points (103, 105) are provided at the free ends of the sections (102, 104), thereby enabling independent connections to be made for different modes, such as transmit and receive. Top-loading and additional short-circuit elemen...

A bearing arrangement for a gear pump comprises first and second separate bearing blocks each having a respective block housing. The first and second bearing blocks together defining an axially directed bearing surface including a bridge region formed from an erosion resistant material which acts to separate inlet and outlet ports of the pump and a second region formed from a reduced friction material. The bridge region is defined by first and second insert members cast within respective ones of...

For a connection between two multiple electrical conductors, a connecting arrangement is proposed which consists of a casing that can be disassembled in such a way that even a multiple electrical conductor that has already been laid, for example a round cable, can be connected to additional electrical conductors at any desired point. Under these circumstances, electrical contact with the individual electrical conductors of the multiple conductor that has been laid is made by means of insulation-...

A circuit arrangement (100) for controlling a first terminal and a second terminal of a preferably contactless integrated circuit, particularly for testing a CMOS circuit, tests a multitude of intergrated circuits simultaneously while using a low-cost structure. The circuit arrangement permits a simple write/read unit assigned to the integrated circuit, and enables the simultaneous testing of a multitude of integrated circuits using a low-cost structure.

A padlock including a lock body (1), a lock shackle (2) movable between locking and releasing positions, and, inside the lock body, bolt means (5) for securing and releasing the shackle (2) in its locking position, and a cylinder lock mechanism (3) for controlling the bolt means (5). The cylinder lock mechanism (3) is replaceably mounted in a separate casing-like fixing unit (6), which is detachably fixed to the lock body, (1). The fixing unit (6) has inner guiding surfaces (6c), which correspon...

A filter arrangement particularly adapted to be used in a "splitter" of an ADSL system where several POTS equipment, e.g., subscriber sets, are connected to a same telecommunication line. The arrangement, located at the customer premises, includes for each POTS equipment a distinct low-pass filter circuit to separate low frequency POTS signals from high frequency ADSL signals simultaneously transmitted over the same copper twisted-pair telecommunication line. Each low-pass filter circuit is prov...

A cutting arrangement (10) includes a pick holder (12) having a bore (14) containing a sleeve (16) within which a shank (18) of a pick (20) is located. The pick (20) and the sleeve (16) each have heads (22; 24). The head (24) of the sleeve (16) has an outer abutting surface (26) and an inner abutting surface (30). The outer abutting surface (26) abuts an abutting surface (28) of the head (22) of the pick (20). The inner abutting surface (30) abuts an abutting surface (32) of the pick holder (12)...

An advance arrangement for use in controlling timing of fuel delivery by a fuel pump comprises an advance piston which is moveable within a first bore and which cooperates, in use, with a cam arrangement of a fuel pump to adjust the timing of fuel delivery by the pump. A surface associated with the advance piston is exposed to fuel pressure within an advance piston control chamber. A light load piston is moveable relative to the advance piston against a spring load due to a light load control sp...

A sensor system is for detecting forces which, particularly in the case of a motor vehicle, lead to a deformation of components, e.g. body parts as the result of an accident. The sensor system includes a number of contact elements which are arranged on the component staggered one behind the other in a possible deformation direction, compressible insulation layers being disposed between the contact elements. The contact elements are electroconductively connected to an electronic evaluation circui...
