Patent GB-2032375-A (GB)
Title: Spillplate for mining conveyer system
IPC: B65G21/00
Filed: 1978-10-31
Abstract: In a coal mine, it is common for coal to be cut on a face and carried along a face conveyor (4) to a roadway (3), where it is transferred onto a further conveyor (1) which carries it away from the face, for removal from the mine. As coal is cut and the face advances, the roadway must also advance ahead of the face. Debris from the cutting of the roadway can interfere with the smooth working of the face and of the transfer of mineral from the face conveyor to the further conveyor. This invention provides a movable spillplate (5) slidably mounted on the further conveyor (1) in the roadway and ram means (7, 8) whereby the spillplate may be moved to an advanced position adjacent the line of a coal face and to a retracted position removed from the face which permits a coal cutting machine to move into the roadway on its traverse of the face. <IMAGE>

Title: Applying Ultrasonic Vibration to Friction Member
IPC: F16D7/02
Filed: 1980-01-23
Abstract: The invention is concerned with the rapid release of frictional force which is acting to reduce relative movement between contacting surfaces, the normal actuating means being unaffected. One application is in an anti-lock braking system in vehicles, particularly motor-cycles. A sensor 3 monitors wheel angular velocity and when this falls below a predetermined value the sensor causes ultrasonic vibrations to be applied to brake pads 2 effectively reducing friction without release of brake operating pressure to enable resumption of normal rotation. A short duration dc pulse of appreciable magnitude may be applied to the transducer at the onset of the normal input signal to produce a short duration surge to rapidly break the frictional force between the friction member and the moveable member to enhance speed of release. The transducer may also be applied directly to the end wall of a friction member hydraulic operating cylinder when ultrasonic vibrations will be transmitted through the operating fluid to the piston connected to the friction member. The end wall of the cylinder is of a suitable matching material to facilitate transmission of the ultrasonic energy and the piston is formed so as to minimise attenuation. The invention can also be applied to friction clutches operating in either rotary or linear senses to cause release when overloading or overspeed occurs or to give gradual engagement in accordance with a predetermined programme. <IMAGE>

Title: Motor vehicle with a sound- suppressing compartment for the engine unit
IPC: F02B77/13
Filed: 1980-02-05
Abstract: The engine is connected to the sump (6) by means of a sound insulating element (7) and mounted so that at least the cylinder block (11) is in a noise suppressing compartment which in addition to the vehicle body parts is defined by walls (12, 13, (14)) so that the compartment surrounds the cylinder block (11) closely. The compartment is completed on the upper side by the bonnet (20) and on the lower side by a flexible membrane (15). By arranging for the carburettor (21) to be mounted outside the compartment with the induction manifold (23) inside, and for the exhaust manifold (27) to have its own sound suppressing shroud (31) on the outside of the compartment, it is possible to bring the compartment walls nearer to the cylinder block (11) without affecting the accessibility of parts requiring regular maintenance. This arrangement gives rise to better sound suppression and engine cooling at low cost. The compartment itself may be cooled by a fan (33). <IMAGE>
Patent GB-2076157-A (GB)
Title: Measuring Vehicle Speeds Electrically
IPC: G01P3/489
Filed: 1980-05-13
Abstract: Pulses from a propeller shaft rotation sensing generator at a rate proportional to the rate of rotation are supplied to an input terminal 101 and set a bistable B connected to a sense B input terminal of a microprocessor IC1 to which time pulses at 3 millisecond intervals are supplied through a bistable A to a sense A input terminal from a 4 MHz crystal 106 with a divider chain IC4, IC5 and 1 DIVIDED 2 IC6. The sense A input is an interrupt request and an interrupt program stored in an EPROM IC3 causes the microprocessor IC1 to survey distance and elapsed time measurement inputs at PA0 and PA1 of a memory and interface IC2. A distance latch 121 controlled by manually operable distance start and stop switches 104 and 105 provides high for distance measurement and low for no distance measurement. Similarly, a time latch 120 with time start and stop switches 102 and 103 provides high for time measurement a low for no time measurement. Time and distance memory areas in IC2 are allocated to counting elapsed time by incrementing once every e.g. 12 interrupts, and distance by incrementing once every e.g. pulse at input terminal 101. Other memory areas may be incremented at rates related to the interrupt frequency to provide time of day in hours and minutes. To display distance and time of day and to calculate elapsed time, average speed, and actual speed, a display unit 107 receives calculated numbers of display clock pulses from IC2 or from a times-ten-multiplier 110 driven by the pulses received at the input terminal 101. The nature of the display or calculation and display is set by the setting of a function selection switch 108 determining inputs at PA3, PA4, PA5 and PA6 of IC2. The calculations are carried out in accordance with a main program which establishes and utilizes a stack in IC2. The number of input pulses at input terminal 101 generated during a reference distance is entered into the stack by use of a calibrate switch 113. <IMAGE>
