Abstract: A motion transmitting device including eccentric means 5 (Figure 2), wheel means 7 having portions 31, e.g. teeth, shaped to engage with teeth 29 on links of a chain and having movement-limiting means including a datum member so that the teeth on the links move into and out of engagement with those on the wheel means can form a speed changing or torque conversion device in which the load is spread over approximately a quarter of the teeth enabling high torques to be obtained. The present invention provides an improved form of movement-limiting means for such a quadrant drive transmission device in which certain practical limitations to the load-carrying capacity are avoided. This is achieved by providing rollers 23 each engaging a first ovoid hole41' on the datum member40 and engaging a second ovoid hole 41 on a meshing element 31, the meshing elements being separately hingedly connected by pins 21, so separating a number of functions which were all performed by the chain link pins in the prior art.

Abstract: A display arrangement consists of a cathode ray tube 1 in which electrons from a flood gun 2 pass through a segmented mesh electrode 7, different portions of which can be selectively switched to enable the electrons to reach only selected portions of a fluorescent screen 3. As very low switching voltages are applied to the mesh electrode 7 to control the passage of electrons from the flood gun 2, the cathode 23 is heated to the temperature at which electrons are emitted by the application of relatively short high current pulses produced by a drive circuit 25. Electrons are allowed to pass through the mesh electrode 7 only during the intervals between these pulses.

Abstract: A linear motor actuator for a magnetic read/write head has its stator located between a pair of disks within a stack of magnetic recording disks. The stator comprises an array of reversed polarity magnets 42,43 (preferably permanent) in a linear array, the two end magnets 42' being half the width of the others. A pair of flat coils 24, 25 are the drive elements of the armature of the motor with the coils arranged in side-by-side relationship for bridging from magnet to magnet of the stator, so that the armature will not stall between magnets. The actuator is controlled by an external microprocessor electronic control system for selecting any position precisely, rather than in steps as in a stepping motor. The microprocessor effects servo control of the actuator and its direction of motion based upon feedback signals. The stator arrangement including plates 41,42 and end magnets 42' reduce fringing flux thereby allowing said stator location between the associated pair of disks.

Abstract: Reverse osmosis pumping apparatus (12) for pumping under pressure feed fluid (16) to selective membrane means (15) which permeate and reject respectively permeate and concentrate fluid fractions (18, 19). Apparatus has a feed cylinder (25) divided into pumping and expansion chambers (30, 31) by a feed displacer (24) mounted on displacer rod (26) for relative reciprocation. Main valve controls concentrate fluid flow relative to expansion chamber (31) and is mounted for movement relative to and along displacer rod axis and is responsive to force applying reciprocation action to pump such that reversal of force reverses main valve. Recirculating pump (53) can be driven from displacer rod to pump concentrate fluid over membranes to maintain permeate fraction discharge during induction stroke of feed cylinder. Recirculating pump has valve also actuated by reversal of pumping action to direct concentrate flow to membranes, or to the expansion chamber for depressurization to assist in pressuring feed fluid. Because main valve mechanism is actuated by change in reciprocation action, it is not necessary to complete a full displacer stroke before stroke direction reversal. Thus apparatus is particularly suited for power sources which have a non-constant amplitude and frequency, such as manual, wave or wind power sources.
