Patent GB-2105504-A (GB)
Title: Coal pipe monitor
Inventor: LAPLANTE DONALD W
IPC: B65G53/66
Filed: 1981-09-09
Abstract: In apparatus for monitoring the flow of coal from a bunker through a conduit to a coal feeder (18), a radiation-sensitive detector (32) detects the amount of coal present at a zone of the conduit and generates a stream of pulses which is sampled at discrete time intervals to determine whether the conduit zone is empty, partially filled or filled. If the conduit zone is partially filled, a partial alarm (120) is generated, and a determination is made as to whether the conduit zone is empty. If the conduit zone is empty, an empty alarm (122) is generated and the feeder (18) is stopped after a predetermined amount of coal has been deposited on the feeder. If the conduit zone is partially filled and a shut-off valve (14) between the bunker and the conduit is closed, a coal build-up alarm (128) is generated. If the conduit zone is filled and the profile of coal at the feeder is not at full profile, a coal hang-up alarm (126) is generated. If the conduit zone is partially filled and the profile of coal at the feeder is at full profile, a vent alarm (124) is generated. A self- testing circuit periodically simulates each of these conditions to test the apparatus. <IMAGE>

Title: Draught excluder
Inventor: CARNEY DEIRDRE
IPC: E06B7/23
Filed: 1981-09-18
Abstract: A draught excluder consists of two fabric-covered cylindrical pieces of resiliently compressible material connected together along their length by nylon webbing. The cylindrical pieces are disposed on opposite sides of the foot of the door, the webbing being of a width to cause them to grip the door tightly, and one of the pieces being shorter than the other by a couple of inches to fit within the door frame. The fabric coverings are secured at each end by a draw string sewn inside. Engagement of the cylindrical pieces with the door on the one hand and the floor on the other provides effective exclusion of draughts. <IMAGE>

Title: Improvements in model train systems
Inventor: LANE DAVID SILVESTER
IPC: H02P5/68
Filed: 1981-10-05
Abstract: A two locomotive model railway system is described having two rails (12, 14) in which each locomotive is equipped with a current rectifying device (22; 28) connected in series with an electric motor winding (20; 28) wherein electric current pulses of one polarity from an alternating supply (36) are directed to the one motor and pulses of opposite polarity are directed to the other motor, and the means current to either motor is controllable to vary the speed of the motor independently of the other. Current control may be by variable resistor (48 or 50), variable transformer, or by thyristor or triac based rectifying circuits. Smoothing capacitors (24; 30) serve to iron out short-term variations in the current supplied to the rails. The system allows the locomotives to be driven in one direction only. <IMAGE>

Title: Process for producing chlorobenzene sulfochloride
IPC: C07C309/86
Filed: 1981-10-06
Abstract: A process for producing chlorobenzene sulfochloride comprises adding a reaction mixture of chlorobenzene and chlorosulfonic acid to water or diluted sulfuric acid to decompose excess chlorosulfonic acid; driving off hydrogen chloride thereby generated, from the system; bringing the sulfuric acid concentration in the sulfuric acid layer upon completion of the decomposition to be from 60 to 90%; and then separating chlorobenzene sulfochloride. The chlorobenzene sulfochloride is separated in a liquid state at a temperature of from 50 to 80 DEG C. Further, water used to wash and purify the chlorobenzene sulfochloride is reused as a water source for the decomposition of the excess chlorosulfonic acid in the process. Furthermore, the sulfuric acid layer separated from the chlorobenzene sulfochloride layer is cooled to separate a precipitate, which is then reused as a feed material for the preparation of the reaction mixture of chlorobenzene and chlorosulfonic acid.

Title: Cable drum road carrier
IPC: B65H49/32
Filed: 1981-12-14
Abstract: A cable drum carrier comprises two pairs of road wheels 3 having associated manually operable braking means and means 4 for rotatably mounting a cable drum D on the carrier. The carrier also includes two adjustable pairs of flanged wheels 2 for supporting the carrier on a railway track R, the arrangement being such that when the carrier is supported on a railway track, the road wheels are spaced from the track and are freely rotatable. When the carrier is supported on a track, adjustable means 5 rotatably couples the road wheels to a cable drum D when rotatably mounted on the carrier so that, when cable is unwound from the cable drum, the rotatable speed of drum can be controlled by the braking means of the road wheels. The drum carrier is especially suitable for paying out overhead conductor or catenary wire. The carrier may be suitable for towing or may carry its own means of propulsion. <IMAGE>

Title: Controlling lock-up clutch hydrodynamic transmitter
Inventor: AOKI TAKASHI

Filed: 1984-11-08
Abstract: In a transmission for an automotive vehicle, a control system for a direct-coupling mechanism Cd for mechanically engaging input and output members 2, 3 of a hydraulic power transmission means T. Operating fluid pressure regulating means controls operating fluid pressure applied to a hydraulically operating portion 13 of the direct-coupling mechanism, and the direct-coupling mechanism applies an engaging force corresponding to the operating fluid pressure thus controlled to the input and output members. Vehicle speed sensor means 103 detects the speed of the vehicle, and slip sensor means 103, 106 detects the value of a predetermined parameter indicative of an amount of relative slip between the input and output members. When the detected vehicle speed falls between a first predetermined value and a second predetermined value larger than the first predetermined value and at the same time the detected value of the predetermined parameter is outside a predetermined range, control means causes the operating fluid pressure regulating means to vary the magnitude of the operating fluid pressure so that the predetermined parameter falls within the predetermined range. <IMAGE>
