Title: Insulated sill member with water drain
Inventor: AGUILAR JOSE
IPC: E06B1/70
Filed: 1982-04-01
Abstract: An extruded elongate member for use in a door or window frame or surround is a sill member and comprises a first two-part "thermal break" section fitting slidingly into a second two-part "thermal break" section. One of the sections (Figure 1) incorporates the sill whilst the other section (Figure 2) forms in use a rail of the door or window frame or surround. Drain holes (15) extend from front face to rear face of the sill section and emerge adjacent the surface of the thermal insulating material (13) without extending into that material. The fit between the two sections is ridged (27, 28) to increase the frictional grip between the two sections and also to form a labyrinth seal resisting rain blown up off the top of the sill in use. <IMAGE>
Patent GB-2100538-A (GB)
Title: AM or FM demodulator
IPC: H03D5/00
Filed: 1982-06-09
Abstract: A sampling demodulator is adaptable as both a frequency demodulator (where the bandwidth of modulating frequencies is small compared to the fundamental carrier frequency) and as an amplitude demodulator. In the amplitude demodulation mode the demodulator is able to produce an output with no residual undulating ripple even when the modulation and carrier frequencies are relatively closely spaced. The amplitude demodulation is achieved by sample-and-hold devices (19,20) which track and hold the maximum value of alternate odd and even- numbered positive and negative-going half cycles of the carrier. The hold values are output to a combining device (25, 26, 28) which produces a step function output, each step being one carrier cycle long. The sample-and-hold devices are controlled by timing pulses (17, 18) which are produced by timing circuits (7, 8, 10, 11, 12, 15, 16) from the zero-crossing points of the carrier. In the frequency demodulation mode the sample-and-hold devices (19,20) are arranged to track and hold the value of the carrier every n/fo seconds after a zero-crossing of the incoming signal (n = an integer and fo is the fundamental carrier frequency). <IMAGE>

Title: Measuring while drilling tool
Inventor: CLAYCOMB JACKSON REYNOLDS
IPC: E21B47/18
Filed: 1982-11-08
Abstract: A measuring while drilling tool includes a closed circuit hydraulic system which is energised by variations in mud pressure and serves to modulate mud back pressure to provide surface signals indicative of well parameters. The hydraulic system includes a low pressure reservoir (215) from which five transducers are charged with fluid via a fill valve (147). The volume of fluid needed to charge each transducer is dependent on the value of the parameter detected by each transducer. Each transducer is provided with a detent valve, the detent valves being connected to a common manifold (150) and being operated in sequence by an enlargement (127) on the rod (126) of a hydraulic ram (124). When a particular detent valve is opened by the enlargement (127) the fluid contained in the associated transducer is dumped into the common manifold (150) and controls a hydraulic ram via lines (185, 200) whereby the flow area of a mud flow orifice is restricted for a period of time proportional to the volume of fluid in the particular transducer. Parameters detected may include tool inclination and magnetic heading. <IMAGE>

IPC: F41H7/02
Filed: 1983-03-14
Abstract: In manufacturing a range of different types of tracked vehicles to be used as military tanks eg. fighting, reconnaissance, defensive and supply tanks standardized basic armour-plate housings 1, 2, 3, 4, 12 to 18 are mass-produced and the resulting housings are then subjected to modification or adaptation, for example by the addition of special-purpose armour plating (23, Figures 3 and 4) and/or other supplemental parts, as necessary to produce the required different types of tank. Advantage can thus be taken of the economic benefits of mass production methods, without unacceptable sacrifice of fighting power, in particular by forming the joints 11 between all the armour plates in such a way as to be weldable by automatic means.   <IMAGE>

Title: Rocking assembly
Inventor: WAYMOUTH DAVID CHARLES RIDLEY
IPC: A47C3/029
Filed: 1985-03-01
Abstract: A rocking chair, horse or similar is fitted with a hinged elongate member (or members 61, 62) free to swing beneath the seat but restrained from swinging beyond the midpoint or vertical at which point it projects a small distance below the rockers so that the assembly will, on rocking back, rise on the projection and be propelled forward until the member has swung within the arc of the rockers. The restraining mechanism is arranged to restrict movement in one direction or the other and, by using two or more elongate members fitted with means for withdrawal within the arc of the rockers, the assembly becomes both reversible and steerable. A number of mechanisms for reversing and steering are shown and a variety of applications described. In one embodiment, the arcuate rocker is a portion of a hemisphere and is provided with four slots through each of which an elongate member projects, a joystick connected to wires controlling the positions of these members. In a further embodiment, a "caterpillar" arrangement of several independently pivotable and controllable elongate members is employed. <IMAGE>

Title: Electrochemical gas sensor
Inventor: HOLSCHER UVO
IPC: G01N27/49
Filed: 1985-05-23
Abstract: An electrochemical gas sensor consists of a chamber (1) with electrode and counter-electrode (6). The opening of the chamber facing the gas to be measured is sealed by a porous glass layer membrane in contact with measuring electrode 2. The chamber is filled with an electrolyte (8). The measuring electrode is preferably formed on the glass layer either as a metallic layer with apertures or as a porous metal layer covered with a layer of insulator containing apertures. The defined pore structure of the glass layer (9) ensures compensation of flow effects within the gas to be measured and prevents the influence of drops of condensate which may cover the surface portions of the layer (9) and which would otherwise thereby disturb the diffusion of the gas to be measured. <IMAGE>
