Title: Wandering drone car
IPC: A63H17/38
Filed: 1979-07-05
Abstract: A toy vehicle game has a plurality of controllable toy vehicles which collect current from conductor strips in a slotless track and switch lanes when current polarity is reversed. A toy drone car is used in the game which collects current from the strips associated with the other cars and it includes an electrical circuit which insures that current of only a predetermined desired polarity is supplied to the motor in the vehicle to propel the vehicle in a forward direction around the track. As a result, the vehicle is driven about the track in a forward direction regardless of the polarity of current applied to the collector strips. In addition, the drone car includes an automatic steering system which causes it to continuously switch lanes in an apparently random alternating manner as it moves along the track. <IMAGE>

Title: Masking frame
IPC: G03B27/58
Filed: 1979-11-19
Abstract: A photographic masking frame is described in which there is a base plate and a raisable frame 4 which holds the print material flat on the base when in the working position and which has an opening in it which is closable by a removable square mask formed in two portions 10, 11. One of these portions 10 is L-shaped and covers substantially three quarters of the area of the opening and the other of these portions is square and covers the remaining quarter of the opening. The removable mask as a whole can be lifted as a single unit, e.g. to expose the whole area of sensitive paper and fits into a square recess of approximately the same dimensions which is made in the top surface of the raisable frame. The area of the recess is greater than the area of the aperture in the frame. The square portion of the mask is raisable without disturbing the L-shaped portion of the mask e.g. to expose only a quarter of the area, and overlaps the adjacent edges of the L-shaped portion of the mask and so renders the joint light-tight. Also described is the use of two additional masks 19, 20 which fit into the recess and one of which has a rectangular aperture 21 for making rectangular prints. <IMAGE>
