Abstract: A video signal processing apparatus used for a video tape recorder is disclosed. In the apparatus, the chrominance signal is up-converted in a frequency converter (30), digitalised in an AID converter (32) and phase-shifted in a recording block (40); and, in a reproducing block (26), phase shifted in the opposite direction in a reproducing block (26), filtered by a comb filter, compensated against jitter, and up-converted to the original chrominance signal in the frequency converter (30). Both the recording block (40) and the reproducing block (26) may be digitalised or only the reproducing block (26) may be digitalised. The digital chrominance signal processing circuit includes an AD converter, a digital phase shifter, a digital comb fitter, a digital jitter compensator, and a DA converter.

Abstract: A method and apparatus as disclosed for retorting particulate solid materials, particularly hydrocarbon-containing materials such as oil shale, oil sands, tar sands, coal shale; coal tailings, and the like, for the recovery of a volatile constituent such as oil or gas. 
     The rotary retorting apparatus consists of a cylindrical drum (1), or other similar regularly shaped chamber, with a substantially horizontal axis of rotation and having multiple compartments (6, 7, 8) for retorting and combustion and, optionally, spent solids cooling. The apparatus further includes solids transport chutes (20, 23, 24) for forward and backward circulation of solids, arranged for the intercompartmental transfer of solids with the capability of additions at one or more points in each compartment. 
     The method comprises particulate solids feedstock being heated by recycled spent solids material to remove the volatile constituent of the feedstock in the retort section, and direct solids to-gas contact being established by lifting and cascading reacting solids through hot gas streams such that throughput, high thermal efficiency and low energy input are obtained in producing high yields of volatile product. In particular, high oil yields and gas yields are obtained when processing oil shale, but with low sulfur oxides, nitrogen oxides in the flue gases and reduced hydrogen sulfide in the retort gases.

Abstract: Spring-assisted shift apparatus includes a plate (28) rotatable about an axis (A) to a plurality of positions, the plate defining a cam track (32,34). A cam follower (22, 26) is operatively associated with the cam track, and is adapted to move a shift fork (16, 18) in response to selective rotation of the plate. A spring-assist mechanism includes an assist cam track (58) defined by the plate so as to have an arcuate first track surface (60) with a center of curvature on the axis, and a second track surface (62) oriented such that a line perpendicular thereto does not intersect the axis. A spring member (48) supports an assist cam follower (56) in operative association with the assist cam track such that the assist cam follower (56) is in contact with the first track surface (60) when the plate is in one position, and is in contact with the second track surface (62) when the plate is in another position. The spring member is stressed so as to apply a preload biasing force on the plate.

Abstract: A special purpose microprocessor based system, comprising weighing element, stored printing ink formulation data, and operator interface designed to aid the process of mixing defined colours and shades of printing inks from a small number of constituent basic colour inks. Once the colour and quantity of ink have been entered, the system prompts the operator through the mixing process by displaying constituent basic colour inks and quantity to be added. The actual amount of constituent basic colour ink then added is monitored by the weighing element. Repeated operation for each constituent thus ensures accurate, reproducible and error free mixing to the required formulation.

Abstract: A programmable read-only memory device comprises a memory cell transistor (Q<sub>3</sub>) which has a source, a drain, a floating gate, and a control gate formed over the floating gate. Programming of the device is performed by applying a high voltage (RWS) to the control gate and a high voltage (CLM) to the drain of the memory cell transistor. The high voltages are applied to the memory cell transistor under the control of respective program signals (DPGM, PGM). The device further comprises means (Q<sub>4</sub>-Q<sub>11</sub>, C<sub>l</sub>-C<sub>3</sub>) for delaying the program signal (DPGM) for the control gate voltage, relative to the program signal (PGM) for the drain voltage, during the programming operation. The application of the programming voltage to the control gate is therefore delayed relative to the application of the programming voltage to the drain, which ensures reliable data writing even if the programming voltage level is less than normal.

Abstract: A borehole probe (36) includes a soft outer plastic cylinder (42) secured to a central mandrel (39) and inflatable by hydraulic pressure conducted therethrough to impinge upon the sidewall of a borehole (22) with controlled pressure. A plurality of LVDT diameter sensors (67) are secured to the probe (36) in planes perpendicular to the axis thereof and spaced angularly thereabout. A plurality of acoustic transducers (73) is also secured to the exterior of the probe to monitor acoustic emissions as well as to survey the earthen media with ultrasonic emissions. 
     The cylinder inflation pressure is increased gradually to exceed both the tensile strength of the media and also the principal stress therein to initiate fracture of the media surrounding the borehole. The cylinder (42) is then deflated to unload the fractured media, and gradually reinflated to first elastically deform the fractured media and then re-expand the fractures previously created. The diameter data together with the hydraulic pressure and the acoustic emissions data and ultrasonic data are analysed to determine the major and minor stress fields in the media, and also the tensile strength, yield strength, and deformation characteristics of the borehole media. 
     The construction of the probe and the diameter measuring means may be varied when higher pressures are to be used and greater changes in diameter are expected.

Abstract: @ A dispensing device for a bactericidal pellet such as chlorine tablets which is readily adapted to being placed on a hopper container for the pellets and which can dispense the pellets such as in conjunction with a well or a water recirculation system while employing a minimum number of parts. The pellet dispenser employs a unique rotor member with pellet carrying passages designed to dispense the pellets from the hopper and out of the pellet dispenser in an individual manner and without jamming. In the instance where pellets may become improperly placed in the pellet carrying passages so that the rotor does not properly move inside the rotor housing, a bi-directional self-reversing motor is utilized so that the tablet dispensing sequence will continue in an accurate manner. This is effected in part by a bidirectional rotor member which is able to dispense tablets in a clockwise or counterclockwise manner.
