Patent GB-2274433-A (GB)
Title: A hitch mounted electric towing unit
Inventor: WILSON BARRY CHARLES
IPC: B62D51/06
Filed: 1993-01-20
Abstract: A hitch mounted electric towing unit comprises a hitch locking system (1) for looking into the standard towing hitch of a trailer or caravan, the means of propulsion, e.g. a battery (5) which provides the power to drive an electric motor (3) which in turn is connected to a gearbox (4) onto which are mounted the pneumatic wheels (6) or tracks (37, fig 6). The speed (1/2 mph max) and direction (e.g. forward/reverse) is controlled by twistgrips (48, fig 10) on either ends of the handle assembly (9) which are moved by the operator to right or left to steer the unit. This pedestrian controlled vehicle is designed to aid the physical effort needed to manoeuvre uncoupled trailers. <IMAGE>

Title: Control channel timing detection and self correction for digitally trunked simulcast radio communications system
Inventor: BROWN THOMAS ALFRED
IPC: H04B7/26
Filed: 1993-02-26
Abstract: A control channel timing monitor for a simulcast radio frequency (RF) digitally trunked mobile radio communications system continually monitors the outbound control channel timing of each of plural simulcasting transmitting sites. The timing of such monitored signals obtained "over the air" is compared relative to one another and/or to a reference. Fault indications identifying specific sites having faulty synchronization are produced when such comparison indicates lack of synchronization within a programmable tolerance. Appropriate corrective action (e.g., bringing down the control channel and transferring its function to a frequency formerly used for working channel functions) is taken.

Patent GB-2290435-A (GB)
Title: Signal transmission system; security system control
Inventor: HONEYMAN EWEN
IPC: B60R25/10
Filed: 1994-05-18
Abstract: The transmission system has an electrically conductive probe 2 connected to the output of a generator 3, 5, 6, 7 which generates a radio frequency signal at a frequency (eg. 1 MHz) at which the probe 2 is substantially non-radiative, and the probe only transmits the RF signal when it is proximate sensor means 8, 12 connected to an RF receiver 10. The system may be used to disable an alarm and operate locks of a vehicle. An electronic key fob 1 houses the probe 2 and the generator, which in response to closure of a power switch 4 causes an RF carrier to be modulated by a code generator 3. The switch 4 is closed by pressing the probe 2 against the metal bodywork 8 of the vehicle, the modulated RF signal being transmitted into the metal bodywork 8 by direct electrical contact or capacitive coupling. A detector 11 senses the signal between bodywork 8 and a static line 12 formed by an electrical conductor extending from within the vehicle into the surrounding atmosphere. "Anti-grabbing" protection, to avoid the security system being overcome by scanning/analysing equipment, includes a timer 5 which limits the duration of transmission from probe 2 to a period of about four code words, and an anti-scan circuit 17 which disables a decoder 18 in the receiver for a certain period if a received code word is longer than an expected code word. <IMAGE>

Title: Setting apparatus for hydraulic downhole tool
Inventor: ECHOLS III RALPH H
IPC: E21B34/00
Filed: 1994-06-28
Abstract: A hydraulic setting apparatus (20) has an isolation sleeve (26) which covers setting ports (28) and prevents entry of hydraulic setting fluid into a pressure settable tool such as an inflatable packer (22) or a hydraulic packer. The mandrel (30) of the setting tool is mechanically coupled to the mandrel (34) of the pressure settable completion tool by a guide tube (36) which provides an enlarged counterbore chamber. The guide tube (36) is intersected by radial setting ports (28) which permit entry of the pressurized fluid for pressurising a hydraulic pressure chamber (48) in the completion tool. The shiftable isolation sleeve (26) opens and closes the setting ports (28). A radially outwardly biased split C-ring (52) is engaged against the bore of the isolation sleeve. Longitudinal travel of the split C-ring (52) is limited by a shear collar (56) which is releasably pinned to the isolation sleeve (26). <IMAGE>

Title: A wind propelled model control line aeroplane
Inventor: LUCKMAN PETER BERNARD SHAW
IPC: A63H27/00
Filed: 1994-07-01
Abstract: A model control line aeroplane is propelled using, structures such as sails, wings or other aerodynamic surfaces without the assistance of an internal combustion engine or other power unit. The structures are mounted about the aeroplane in such a way that when the wind impinges on them the model aeroplane is propelled forwards with a combination of thrust and lift from these structures. Suitably the structures are in the form of sails 2 which are pivoted at their leading edge to a point on the centre line of the aeroplane, and are feathered at their trailing edge by means of springs 13. In an alternative embodiment (Figs, 5 and 6), the structures may be fixed rather than movable and may be an integral part of the aeroplane; thus, in Fig. 5 there is shown an aeroplane having a deep sided fuselage having an aerofoil section to generate the necessary forces of lift and thrust. <IMAGE>

Title: Connecting buoys to vessels
Inventor: BORSETH KNUT
IPC: B63B21/00
Filed: 1994-09-26
Abstract: A method of catching a line, such as a sink line 3 lowered through a shaft 2 in a vessel, or a pick up line 8 attached to a submerged buoy 9, involves the use of a catch line 5 provided with weight means 7 and suspended in the form of a "U" eg from a derrick 6. The catch line 5 may be provided with hooks. The sink line 8 may be provided at its lower end with a hook (11, Fig. 2) or with a variable buoyancy device comprising a ballast compartment and a compressed air source which is automatically released to expel the ballast at a given depth to cause the end of the sink line to float up in front of the vessel, enabling the line 5 to be caught. In order to connect the buoy 9 to the vessel, the sink line 3 and catch line 8 are caught and hauled on deck in turn. They are connected together then the line 3 is pulled in, thus drawing the buoy to the shaft. <IMAGE>

Title: Pendant Disc Pipe
Inventor: WILLIAMS IAN GILBERT
IPC: A24F3/00
Filed: 1995-03-21
Abstract: A smoking pipe includes a body 3 housing several bowls 6 for receiving a smokeable substance and a moveable cover 1, able to allow access to any one of the bowls, or to cover them all and transform the pipe into a pendant or other clothing accessory. The body and cover are circular and flat, secured together by their centres 8 so that the cover can rotate over the body. The cover has an access hole 2 offset to line up with the bowls, or a through hole 4 in the body. Each bowl communicates with an outlet hole 5 at the edge of the body to allow smoke to be drawn through the pipe when the cover is in position. When hole in the cover lines up with the through hole in the body it may be threaded as a pendant, locking the cover in position and sealing the bowls.

Filed: 1994-08-01
Abstract: In a machine tool a reference straight-edge is mounted on the worktable of the machine tool and the position of the worktable and therefore the workpiece along the x-axis of the machine is determined by reference to the straight edge; a linear scale is mounted to move with the tool and a reading head associated therewith provides a measure of the position of the tool along the x-axis of the machine, and a linear scale is mounted to move with the worktable and a reading head associated therewith provides a measure of the position of the worktable and therefore the workpiece along the z-axis of the machine; wherein the linear scale mounted to the tool and the reference straight edge mounted to the worktable and the reading heads and sensors associated therewith are all mounted in the same plane, and the machine is mounted so that the said plane is horizontal. The linear tool scale is aligned with the tool axis which intersects the point of application of the tool to the workpiece. The reference straight edge sensor is also located on the same so as to be on the same straight line as the linear tool scale and the point of application of the tool to the workpiece. The reading head for the linear scale mounted to the worktable is also located in the same vertical plane containing the said tool axis. Where the tool is a grinding wheel, the wheel is mounted with its axis of rotation at the same height as the reference straight edge and the linear scale associated with the wheel.
