Title: Lamp of adjustable luminous flux
IPC: H05B37/02
Filed: 1979-05-23
Abstract: An adjustable luminous flux lamp (1) suitable for dental surgeries comprises a sensor switch (6a, 6b) on the handle thereof and an electronic circuit (16) connected to the sensor switch (6a, 6b) for continuously adjusting the lamp luminous flux between maximum and minimum values and alternatively switching off and on the lamp. With the lamp (1) off and main switch (19) on, a short duration pulse on a sensor switch lights the lamp at full intensity. A longer pulse caused by resting a finger on one of the sensors causes a cyclic decrease and increase in lamp intensity under the control of integrated circuit (21) which operates as a mains cycle counter causing triggering delay of triac (22). Removal of the finger causes the lamp to remain at the required intensity level until it is extinguished by another short duration pulse, a further short duration pulse switching the lamp on again at its previous intensity.   <IMAGE>

Title: Data Processing System Having a Reading and Recording Magnetic Unit
IPC: G06F3/06
Filed: 1979-07-10
Abstract: In a data processing system a programmed controller 104 for a peripheral unit controls the transfer of data both in the read mode and in the write mode between a magnetic record SM and a data source SD which includes central processor CPU 100 and a system store 101. When the controller 104 is carrying out a read transfer it is commanded in correspondence to each recording position reached on the record SM and carries out sequential reading of the information, decoding of it and storage in internal registers. When the stored information makes up a word, the controller performs a direct memory access operation to the system store 101 independently of the CPU in order to transfer the read word in parallel to the store from where it may be accessed by the CPU. Conversely, when a record transfer is performed the controller has access to the system store 101 independently of the CPU, stores the word read and then records it serially on the record according to a predetermined coding. The controller comprises a program store R0M. The read and write programs take place independently of the CPU which speeds up operation of the controller; there is no need to access CPU programs. <IMAGE>

Title: Synchronisation of ramp voltage
IPC: H03K4/502
Filed: 1979-07-19
Abstract: A circuit arrangement is disclosed for the interference-free synchronisation of a linear ramp voltage. It comprises a constant current source (1) to charge a capacitor (2) linearly in time, and a comparison stage (3), to which is fed a preselectable comparison voltage value and the stored voltage of the capacitor (2). When the voltage of the capacitor substantially equals the comparison voltage, the comparison stage (3) delivers a control pulse to a trigger stage (4) to discharge the capacitor (2). A zero transition trigger (5) connected to an alternating current source delivers a synchronising pulse to the trigger stage (4) to cause a periodic recharge of the capacitor (2). A switch (6) may be connected to be actuable by the trigger stage (4) to effect discharge of the capacitor (2). <IMAGE>

Filed: 1980-07-29
Abstract: A dispenser for dispensing cups singly from a stack of cups has a plurality of cams (18, 28) spaced about a vertical axis (16), coaxial with the axis of the stack of cups, and drive means (20) for rotating the cams together about their associated axes (19). Each of the cams has a cam face (30) which is a helix about its axis and is arranged to engage the rim of the end cup of a stack of cups located in the dispenser so that rotation of the cams pushes the end cup away from the stack to dispense it. The invention provides that the dispensing cam face of each cam is chamfered, preferably at an angle in the range 22 DEG  to 28 DEG  with respect to a diameter of the cam. Preferably the upwardly directed cam face which engages the next cup in the stack and holds the stack up as the lowermost cup is dispensed is also chamfered, with advantage in the range 19 DEG  to 26 DEG . The spiral angle of the helix of each cam is preferably in the range 8 DEG  to 14 DEG  and the effective length of the cam face preferably extends through at least 270 DEG  around the cam.
