Abstract: 1,201,677. Moulding decorated articles. PLASTOREX S.A. 27 March, 1968 [5 April, 1967], No. 14733/68. Heading B5A. [Also in Divisions B2 and B6] In a process for moulding decorated articles of thermosetting resin, e.g. phenoplast, amino. plast, epoxy, polyester and especially phenol, urea and melamine/formaldehyde resins and mixed condensation products thereof, the resin is pre-moulded to its ultimate shape without completing the cure thereof and a decorated sheet, to one or both sides whereof has been applied a coating of the same or of a compatible thermosetting resin in particulate form, is then applied to the article with the particulate resin externally thereof, whereafter the moulding is completed. The decorated sheet, e.g. of transparent long-fibre cellulose, comprising only the part thereof of a larger sheet on which the decoration has been printed, is sprinkled with powdered resin over the surface intended to be placed externally and passed over a steam generator and subsequently dried, whereby the resin adheres to the paper. The absence of a water vehicle for the resin enables the use of fatty printing inks. With non-absorbing printed papers, powdered resin may be applied to both sides thereof. Gold or silver printed colours based on metal pigments may be used. The printed sheet may be applied to the article with the design on the external or internal surfaces thereof. The prior art processes are specified as using a sheet which is solution impregnated with resin either prior to or subsequent to printing, or an impregnated sheet which is applied to the article prior to the application of resin powder externally thereof. Examples are given of the process applied to the moulding of a circular melamine-based resin article, and to a bowl. The resin used in moulding the article may incorporate inorganic (asbestos, slate, mica, glass fibre) or organic fillers (wood dust, cellulose powder or fibres, regenerated cellulose, natural or synthetic fibre cloth).

Title: Improvements in and relating to electric motor controllers
Inventor: CARTER HOWARD FREDERICK
IPC: H02P1/02
Filed: 1952-06-17
Abstract: 718,647. Controllers. BRITISH THOMSONHOUSTON CO., Ltd. March 19, 1953 [June 17, 1952], No. 15229/52. Class 38(3) In a traction or like system, the operating arm 2 of a master controller is coupled to an accelerating pedal 1 through a spring link 3 which is compressed if the master controller is prevented from following the pedal-movement. When the pedal 1 is depressed, the master controller moves freely from the "off position to the position in which the first contactor is closed. The arm 2 then engages a rod 4 and further movement of the operating arm is adapted to effect rotation of a quadrant 6 to initiate the movement of the rotor of ah eddy current brake 7. A free wheel device 8 allows unimpeded movement of the controller to the " off " position. The eddy current brake 7 is magnetically locked to prevent further controller-movement in the event of excessive motor current, as described in Specification 699,256, [Group XXXV]. The mechanical linkage is arranged so that the torque transmitted to the eddy current rotor is substantially independent of the position of the controller. The coil of the eddy current device is energized from the traction supply source or a battery and is connected in series with resistors which are controlled by relays responsive to high and low values of the motor current, Figs. 2, 3, 4 (not shown). When the motor is heavily loaded the high-current relay removes resistance from the circuit of the eddy current coil to lock the rotor and prevent further movement of the controller until the motor current is reduced. The coil of the low-current relay may be shortcircuited when a contactor, for connecting a diverter resistance across the series field winding, is closed. The excitation of the brake coil is thus reduced to a minimum to prevent over-heating. Specification 696,244 also is referred to.
