Title: Microwave phase shifter
Inventor: REGNAUDIN FRANCOIS
IPC: H01P1/19
Filed: 1988-03-15
Abstract: In a reciprocal microwave phase shifter of microstrip technology, a Ferrite substrate SF carries, on one side. a ground plane (PM) and, on the other, a microstrip line (LM). The lateral branches (CG2) cooperate with a base (CC) to define a magnetic circuit and are in direct contact with the Ferrite substrate (SF), by being, for example, equipped with a recess (ED2) in line with the passage of the microstrip line (LM). Other arrangements are described with no recesses in the magnetic circuit, with the magnetic circuit on the ground plane (PM) side of the substrate (SF) or for triplate construction. <IMAGE>

Title: Transducer system
Inventor: SELMES BRIAN ARTHUR
IPC: G01B7/16
Filed: 1988-04-25
Abstract: A system is provided for processing variable electrical signals from a plurality of strain gauge networks (1, 2, 3, 4) on a structure whereby a resultant electrical output from each network is only a function of a designated force which each network is intended to monitor and has been corrected for a reaction by the network to forces which other strain gauge networks on the structure are intended to monitor. The system includes interconnected processing means (5, 6, 7, 8) for connection to the networks (1, 2, 3, 4) whereby an electrical signal from each network is applied to an associated processing means. Each processing means (5, 6, 7, 8) has means to amplify, and optionally to invert, the signal received from its associated network (1, 2, 3, 4) and also has means incorporating selected electrical resistors (9, 10, 11, 12), to receive from the other processing means and to add to or subtract from the signal, a predetermined proportion of corresponding amplified and optionally inverted signals from the other processing means. Output means (13, 14, 15, 16) is provided for each resultant signal. <IMAGE>

Title: Tunable Fabry-Perot filter
Inventor: ROSS PETER WILLIAM
IPC: G02F1/21
Filed: 1988-05-27
Abstract: Tunable Fabry-Perot filters are used in a variety of optical application, e.g. in the cavity of a laser. To provide such a filter a layer of twisted nematic liquid crystal 3 is placed between the two reflectors 1,2 of a Fabry-Perot device. The resulting twisted nematic liquid crystal cell is driven above its threshold level. This enables tuning of the filter by the changes in refractive index thus produced. <IMAGE>

Inventor: FAULKNER PETER
IPC: B32B3/28
Filed: 1990-08-17
Abstract: A plastics bubble sheet (2) of packing material is manufactured by leading a flat plastics top film (10) from a top film storage reel (12) over a top film heating roller (19) where it is heated to a plastic state and then lead to a drum (5). Pockets (3) are formed in the top film (10) at the drum (5).

Filed: 1991-03-12
Abstract: A telescopic construction includes a first tubular section (30) provided with an axially extending slot (31) and a guide seat (20) having a central through hole (21) and an inclined guide notch (22) extending downward from a top side (200) of the guide seat (20) and communicated with the central through hole (21). The first tubular section (30) extends into the central through hole (21) such that an upper portion of the axially extending slot (31) directly faces the inclined guide notch (22). A second tubular section (40) is slidably disposed inside the first tubular section (30) and has a radial hole (41) aligned with the axially extending slot (31). A positioning member (50), disposed inside the second tubular section (40), has a stud (52) biased to project through the radial hole (41) and the axially extending slot (31). The stud (52) engages the inclined guide notch (22) and an upper end of the axially extending slot (31) when the second tubular section (40) is expanded from the first tubular section (30). Downward movement of the second tubular section (40) relative to the first tubular section (30) causes the inclined guide notch (22) to push the stud (52) into the radial hole (41) to disengage said inclined guide notch (22), thereby retracting the second tubular section (40) into the first tubular section (30). <IMAGE>

Title: Kerosene gas stove
Inventor: PATEL PRADIP CHANDUBHAI
IPC: F23D11/44
Filed: 1993-08-02
Abstract: A kerosene gas stove is used for cooking wherein liquid kerosene is admitted into the liquid to gas convertor and valve assy., the valve sleeve of which is mounted over a gas burner. The liquid kerosene passes through this valve sleeve and is heated during ignition by a kerosene taper which converts the liquid kerosene into kerosene gas that passes through a valve and nipple into the burner pipe and then into the burner. The ignited kerosene gas begins to heat the valve sleeve directly. After a minute, the kerosene taper can be removed, and the flame from the burner is sufficient to carry on the process of converting the continuous flow of liquid kerosene to the valve sleeve into a continuous flow of kerosene gas which reaches the burner and is combusted. <IMAGE>
