Title: Electrode Membrane Structure
Inventor: PAYTON ALAN J
IPC: G01N27/404
Filed: 1980-01-04
Abstract: An electrode membrane structure has an annular support member (42) and a circular membrane portion (44) integrally moulded into the annular support. The membrane support is of sufficiently thin gas diffusible material, at least in the circular membrane portion (44) and has an array of perforations (46) to facilitate removal or separation of the annular support from the membrane portion. The support and membrane portions include an intermediate annular transition zone (52) between them.

Filed: 1980-03-14
Abstract: A preparation of sorbitol which can be compressed has at least 90% by weight of the sorbitol in gamma form and comprises blunt-shaped particles with an orientated micro- needles surface state.

Title: Variable speed passenger transit device
IPC: B66B25/00
Filed: 1980-05-28
Abstract: A system is disclosed for varying the speed of an escalator at a controlled rate between two regulated speeds: a high speed, for transporting passengers; and a lower, idle speed when the escalator is unoccupied. The system utilizes a speed reference unit for generating a scheduled escalator speed signal which is applied to a ramp unit for producing a motor control signal which accelerates and decelerates the motor at a comfortable rate. The entry of a passengers detected by a detector for controlling the operation of the speed reference unit to change the escalator speed from the lower to higher speed. A transit simulator for projecting the movement of passengers on the escalator as a function of motor speed controls the speed reference unit to decelerate the escalator to the lower speed at a predetermined rate, determined by the ramp unit, prior to the exit of the passenger from the escalator.

Title: Alternating potential electrostatic separator of particles with different physical properties
IPC: B03C7/00
Filed: 1982-05-17
Abstract: The separator charges the particles to be separated and passes them through an alternating electric field which has a non-uniform intensity in a direction perpendicular to the forward direction, and which also has field lines curved in the same direction. The particles which move along the curved field lines due to their charge are thus subjected to a centrifugal force which effects their separation. The separator includes a pair of conductive electrodes, the first being substantially horizontal or possibly at an angle from the horizontal and the second mounted facing the first at a predetermined angle to it. The electrodes may be planar or curved. The field is supplied by an ac source operating in the range of 3 to 1000 hz. A mechanical vibrator attached to the first electrode imparts the forward motion to the particles.
