Title: Logging while drilling
IPC: E21B47/12
Filed: 1979-09-18
Abstract: The accuracy of well logging data transmitted from a downhole location to the surface of the earth is verified by generating the data at the downhole location, storing the data in a subsurface assembly in the well, transmitting signals corresponding to the data to the surface through a first transmission system while keeping the data stored in the subsurface assembly, and recording the signals transmitted to the surface through the first transmission system. Thereafter, the subsurface assembly is transferred to the surface, and signals corresponding to the stored data are transmitted through a second transmission system from the assembly to an electronic processing system. The signals transmitted through the second transmission system are then compared with the signals transmitted through the first system. To increase the effective transmission rate of data from the downhole location to the surface, a first set of signals corresponding to the magnitude of a downhole condition as a function of time during a discrete time interval are generated and transmitted through a first transmission system to computer means at the downhole location. The first set of signals are analyzed in the computer to determine properties of the function selected from the group consisting of mean value, positive and negative peak values, standard deviation value, and fundamental and harmonic frequencies and amplitudes. A second set of signals corresponding to the selected values are generated and transmitted to the surface through a second transmission system.

Title: Improvements Relating to Plate Heat Exchangers
IPC: F28F3/08
Filed: 1980-07-04
Abstract: In plate heat exchange or evaporating apparatus with a pack of separable plates, dismantling of the plate pack is a lengthy job which normally has to be carried out in situ.

Title: Output multiplication method an apparatus
IPC: F02B75/02
Filed: 1980-09-12
Abstract: An output multiplication apparatus comprises a solenoid motor in which a stator 1 has protruding poles 11, 12 teeth 11a 12a and single phase magnetizing coils L; a rotor 2 has a pair of axially spaced pole members 22, 23 with teeth 22a, 23a; a d.c. exciting coil L<1> is wound around the rotor axis between the two members 22, 23; a capacitor C is connected in series or parallel with the stator exciting coil to form a resonant circuit; an a.c. power source is connectible to the stator coils L; and a d.c. current source is connectible to the rotor exciting coil L<1>. The capacitive reactance is equal to the inductive reactance presented by the stator exciting coil of the solenoid motor in response to the line frequency so that the total impedance will be Z tau  =  2ROOT R<2> + (XL-XC)<2> = 2ROOT R<2> = R, where R is the sum of the resistance of the capacitor and the d.c. effective resistance in the stator exciting coil of the solenoid motor, Therefore, an increase in the frequency of the power source for the solenoid motor will not result in the proportionate increase in the line voltage, and the output is such that it will have a constant torque under variable operation speed. Accordingly, under the same power input, the output horsepower is proportional to the line frequency. <IMAGE>

All display areas A corresponding to a given power of the base number have a common tonal and/or textural characteristic which is different from the characteristic of each neighbouring display area corresponding to a different power of the base number. Such characteristics are preferably provided by three different colours. The teaching aid further comprises sets of unit indicators (e.g. cubes) for display on the display areas A. Each unit indicator has a tonal and/or textural characteristic identifiable with that of a display area A on which it is to be placed. <IMAGE>

Title: Pneumatic stowing installation and parts therefor
IPC: B65G19/18
Filed: 1981-08-07
Abstract: This invention relates to an installation for pneumatically stowing mineral waste in packs adjacent a roadway formed during a mining operation. The installation comprises a stage loader conveyor having in it a first pan (15) including a griddle (17) in its upper deck plate (16). A second pan (18) having an aperture (20) in its lower deck plate (19) is located nearer the head of the conveyor than the first pan (15).

Each compartment (22, 23) has an inlet (24, 25) for admitting compressed air, and an outlet (26, 27) through which stowable material can be conveyed by the compressed air. In use, mineral and waste are transported over the upper deck plates and stowable material falls through the griddle (17) onto the lower deck plates whence it is moved to the aperture (20). The material falls into the compartments (22, 23) and is conveyed by compressed air through the outlets (26, 27) and hoses (28, 29) to a pack adjacent the roadway. One or both of the inlets (24, 25) may be manually closed by use of blocking plates 35. <IMAGE>
Patent GB-2084102-A (GB)
Title: Improvements in or relating to pneumatic transportation systems
IPC: B65G53/24
Filed: 1981-08-28
Abstract: A pneumatic system for transportation of loose solid materials comprises a plurality of suction hoses (1, 2) extending from a receiver (3) to piles of the material (9). The material is sucked into the receiver by evacuating the system with an exhauster (E) connected to the receiver. Pressure transducers (7, 13) detect the pressures in the respective hoses and partially close respective control valves (4, 12) by control means (14, 15) whenever the detected pressures rise above a certain value, for example as a result of withdrawing one of the hoses from a pile of material, as at 10. Loss of vacuum in the system, resulting in loss of suction at 11, is thereby prevented. Preferably the pressure transducers are provided with bleed holes (8) open to the atmosphere which allow currents of air to flow into the transducers and clear them of blocked material. <IMAGE>
