Title: Heavy iron source producing e.g. uranium oxide ions - by bombardment of a target with a neutral or partly neutralised primary beam
IPC: H01J49/14
Filed: 1975-07-25
Abstract: Source of heavy ions, especially UO2 ions, comprising in a vacuum chamber (a) a soruce of primary ions (b) a charge exchange casing the inelt of which is supplied from the primary ion source and the outlet of which delivers an at least partly neutralised molecular or primary atomic jet, and (c) a target of material to be ionised intercepting the primary jet coming from the charge exchange casign and being located in an enclosure brought ot a potential of opposite sign to that of the ions produced. The use of a neutral or partly neutralised molecular- or atomic-jet permits suppression of the space charge arising when a target is bombarded with an ion beam such as that used in conventional cathode spraying processes which prevents the primary beam of striking the target with sufficiently great flux, and causes a decrease in secondary emission of heavy ions from the target.

Title: Vibratory drive unit - has elastic device with non-linear resistance characteristic to radial weight displacement
Inventor: BRANDER JAMES EDWARD
IPC: B06B1/16
Filed: 1975-09-12
Abstract: A supporting component is fixed to a secondary shaft so that they cannot rotate in relation to each other, and has a weight mounted on it so as to give to the complete assembly a certain amount of imbalance, due to being eccentric to the axis of rotation. Thus the weight is displaced radially outwards and increases the degree of imbalance. An elastic device normally thrusts the weight towards the axis of rotation, and this has a non-linear resistance characteristic to the radial displacement. The elastic device can incorporate a first spring (3) offering resistance to radial displacement over a first speed range, and a second one (4) coming into action at the end of this range to provide additional resistance over a further range.

Title: Control circuit for triac switch - has RC circuit making turn:on independent of trigger pulse duration
IPC: H03K17/13
Filed: 1975-09-26
Abstract: The control circuit, for a triac switch typically for one which switches a heating element on and off, has an RC circuit between the triggering circuit and the triac gate to make the actual turn-on pulses applied to the triac independent of the duration of the pulses leaving the triggering circuit. The RC circuit consists of a first transistor coupled by its collector to the triac gate and over a series timing resistor and capacitor to the base of a complementary second transistor. The second transistor is driven into saturation by the triggering circuit and in turn causes the first transistor to turn on after the time determined by the RC circuit has elapsed.
