Patent GB-2064099-A (GB)
Title: Dehumidifier; Air Conditioner; Drier
IPC: B01D53/26
Filed: 1979-11-29
Abstract: A conventional refrigeration-type dehumidifier has an air cooler 4 such as an evaporator for cooling the air in order to condense out the required amount of moisture, followed by a heater 5 to heat the airstream to the required temperature. According to the invention, an air-to-air heat exchange system 7 is provided which transfers heat from the airstream before the air cooler to the airstream after the air cooler. In so doing, the air-to-air heat exchange system reduces the load both on the air cooler and on the heater. The dehumidifier may be part of an air conditioning system or part of a drier (e.g. for drying wood or pottery). In the case of a drier, hot air passes over the material to be dried and is then recirculated via the dehumidifier. <IMAGE>

Patent GB-2097730-A (GB)
Title: Anti-roll suspension system
IPC: B60G17/015
Filed: 1980-04-08
Abstract: In a vehicle suspension system which counteracts outward rolling during vehicle turning two angled torsion bars 3 which are splined into the axle carrier fulcrum 10 have vertical arms which are operated by a double acting piston 6 the body of which is anchored to chassis member 1 via fulcrum pin 9. When the oil pressure passes through either pipes 8, the piston rod 7 moves the connecting rod 4 in the appropriate direction via the connecting 5. This action increases the resistance of the suspension springs on the outside of the turn and decreases the resistance of the suspension springs on the inside of the turn. Pipes 8 are supplied with oil pressure from an engine driven pump via a pendulum controlled supply valve. <IMAGE>

Title: Control and monitoring system for cigarette packaging machines
IPC: B65B19/28
Filed: 1980-07-28
Abstract: A control and monitoring system for cigarette packaging machines comprises a control station (1) connected in cascade to each of a plurality of remote stations (2 and 3) in turn, in a ring.

Patent GB-2085911-A (GB)
Title: Thermal cracking of heavy hydrocarbons
IPC: C10G9/04
Filed: 1980-10-13
Abstract: A heavy hydrocarbon feed, such as petroleum oil or coal tar, is passed from an inlet 13, e.g. at 480 DEG C and 40 atm into an inner vessel 12 within an outer pressure vessel 12. The cracked hydrocarbon and any coke produced pass through an open bottom end 17 of the inner vessel into the outer vessel, which is maintained at a temperature insufficient to sustain the cracking reaction, e.g. by cooling and recycling liquid withdrawn from it. The product is withdrawn, either continuously or intermittently via an outlet 18 or 23. The coke produced may be fluidised in the outer vessel or may be allowed to settle. In the former case the coke is withdrawn as a slurry and allowed to settle outside the reactor system, while in the latter case the coke is removed through the bottom outlet 21. <IMAGE>

Patent GB-2065750-A (GB)
Title: Chemical cutting apparatus
IPC: E21B43/114
Filed: 1980-11-07
Abstract: A chemical cutting apparatus for cutting objects in well bores is positioned relative to the object to be cut and an igniter fired to activate a gas generator. Pressure from the gas generator causes anchor means 70 to move into contact with the object 90 to be cut, and forces a chemical cutting agent into a chamber containing a reactant. The reaction of the chemical cutting agent and reactant displaces a slidable piston to expose radial exhaust orifices thereby allowing the reacting elements in the chamber to escape with great velocity and to contact the object to be cut in incendiary fashion. Pressure relief means 42 intermediate the gas generator and the chemical cutting agent are provided for diverting a portion of the gas away from the chemical cutting agent so as to reduce the likelihood of release of the chemical cutting agent in the event the apparatus is mishandled or malfunctions. <IMAGE>

The suction bars move apart to open the bag thereby along the entry of spreader fingers (40) which transfer the opened bag from the suction bars to the filling nozzle (1). <IMAGE>
Patent GB-2070254-A (GB)
Title: Nuclear magnetic resonance apparatus and methods
IPC: G01R33/3875
Filed: 1981-01-20
Abstract: A nuclear magnetic resonance (NMR) spectrometer includes magnetic field profiling apparatus for producing two inhomogeneous fields, which when superimposed, result in a static homogeneous field through a controllable volume and an inhomogeneous field in an immediately adjacent surrounding volume. The dimensions of the volumes of the resultant homogeneous and inhomogeneous fields can be controlled by adjusting the current delivered by a power supply to coils in the profiling apparatus. The generation of the homogeneous field allows NMR techniques to be applied to a selected region located entirely within an inhomogeneous body. The uniformity of the magnetic field is such as to allow chemical shift information to be recovered in an NMR spectrum.

Patent GB-2097640-A (GB)
Title: Energy filter
IPC: G21K1/10
Filed: 1982-03-09
Abstract: An energy filter, for enclosing a Geiger Muller tube, comprises a copper sheath (2), open at one end and possessing an aperture (4) at the other, surrounded by a discontinuous jacket (6,7 and 9) of 60-40 tin-lead alloy. The latter, assisted by the copper sheath, reduces those radiant frequencies at which the Geiger Muller tube is most sensitive, enabling the tube to produce a response which is substantially independent of the energy of the incoming radiation. 60-40 tin-lead alloy is a commercial solder of eutectic composition. Consequently the filter is readily constructed by casting the tin-lead parts, either directly onto the copper sheath, or apart from it, for later assembly. The particular configuration of the alloy jacket, comprising two axially spaced rings (6,7) and one end disc (9), and the sheath aperture (4), are chosen to give a circular polar response as nearly as possible. <IMAGE>
