Abstract: An apparatus for indicating to an operative the required location of a component to be assembled on a printed circuit board comprises a projection unit having a projector (45) for optically projecting a sequence of component images formed in a liquid crystal unit onto a circuit board placed on an assembly surface (39) of a bench (2). The liquid crystal unit is associated with light producing and condensing means to illuminate the image formed in the liquid crystal unit, which unit comprises an array of liquid crystals and associated scan electronics to address a given crystal. A programmer (30) is provided for establishing the sequence of component images for a given circuit board and is connectable to a microprocessor of the projection unit. Using a keyboard (24) of the programmer (30) the projection unit (45) is instructed to project a selected component image stored in an electronic pattern library of the projection unit onto the circuit board. The image can then be moved to the required position and the identity of the component image and its position stored in a memory of the projection unit together with instructions for a component dispensing device (40). A complete assembly sequence may be stored in the memory and then recorded on a program record (26) for replay by the projection unit to project the sequence of component images onto a circuit board to be assembled and at the same time dispense each component to the operative in synchronism with the corresponding projected image.

Abstract: A drawer-type circuit breaker arrangement of the type adapted to be disposed in an engaged and disengaged position within a housing (14) and a disengaged position outside said housing (14) on extendable support rails (16) is provided with latches (17) which will prevent the extension of the guide rails (16) until the circuit breaker (12) is moved from the engaged position to the disengaged position within the housing (14). The movement of the circuit breaker (12) to the disengaged position operates the latches (17) to permit extension of the support rails (16) while still preventing movement of the circuit breaker (12) onto the support rails (16). Movement of the support rails (16) to the fully extended position allows the latches (17) to be released by movement of the circuit breaker (12) to allow the circuit breaker (12) to be withdrawn out of the housing (14) onto the support rails (16). Actuating levers (23) for engaging and disengaging the circuit breaker are provided on opposite sides of the circuit breaker (12) for movement in respective slots (14a) and notches (14b) to smoothly and efficiently carry out the engaging and disengaging operation while preventing undesirable vertical movement of the circuit breaker (12) relative to the housing (14).

Abstract: A method of constructing a panel for use in the construction of a wall of a building, the method comprising the steps of: constructing a panel having an opening therein for a door, window or the like, the portion (1, 2, 3, 4) of the panel lying across the top of the said opening having a predetermined load-bearing capacity; and, where the actual load to be carried by the panel exceeds the said predetermined load-bearing capacity, attaching a reinforcing member (7) to the panel to increase the load-bearing capacity of the said portion of the panel. 
     Because the reinforcing member 7 is used only where the load-bearing capacity is to be increased, for example when the panel forms part of a lower storey of multi-storey building, the wastage which is created by constructing all of the panels of the building to have the higher load-bearing capacity is avoided. 
     Variations in the shape and position of the reinforcing member 7 are disclosed. Claims are also directed to the panels per se, to a method of constructing a building and to the building itself.

Abstract: Movement sensor includes a conductor body of the electricity which moves easily over a support the latter also having fixed elements of the electricity. When the mobile conductor body moves over the fixed conductor elements, successive electrical contacts are established. This permits to establish as many different switches as desired throughout the path of the mobile body. With the body placed in a determined position and in an inoperative situation, the mobile conductor body will be positioned at a point of the support which supposes a stable equilibrum. In this situation, the mobile conductor body will seek a new stable position and travel a certain space throughout a curved path, closing switches in its run. The fact that it closes switches at a determined point of the path does not indicate movement. The fact that it closes, at successive times, switches in different zones means that a displacement of the conductor body has been produced, that is, movement of the sensor. The distance between the zones wherein closing of the switches has been produced indicates amplitude of the movement. If the support presents different curvature radii in different zones, a different sensitivity will correspond to each zone. With the mobile conductor body in a zone of great curvature radius, a slight movement will produce a great displacement of the mobile body on the support and, consequently, the closing, at different times, of various switches. An alarm system comprising the movement sensor is also described.
