Title: Electricity supply fault detection
Inventor: HAVILAND DAVID J
IPC: G01R31/58
Filed: 1982-07-22
Abstract: An electricity supply fault detection apparatus is interposed between live and neutral mains terminals 10 and 11 and circuit wiring 13 and 14. The apparatus comprises a circuit breaker 12 arranged to react to an imbalance of current drawn on wires 13 and 14 and an oscillator 15 which generates an output voltage having a frequency significantly at variance with mains frequency. The oscillator output is connected by means of a series linked adjustable resister 18 and isolating capacitor 19 to the live line 13 downstream of the circuit breaker 12 and by means of a line 17 to the neutral mains line 11 upstream of the circuit breaker 12. When a current path is provided between lines 13 and 14 current flows at the output frequency of the oscillator to cause the circuit breaker to respond. By incorporating a choke 22 within the load 20 which presents a high impedance to currents at the oscillator output frequency the load 20 can draw mains current without causing circuit breaker 12 to respond. However, any non-protected load or current path between lines 13 and 14 will cause current to flow at the oscillator output frequency resulting in circuit breaker 12 responding. <IMAGE>

Title: Distributor for cigarette making machine or the like
Inventor: HOLZNAGEL UWE
IPC: A24C5/00
Filed: 1982-11-25
Abstract: A distributor for use in a cigarette making machine has an upright duct with an inlet at the upper end and an outlet at the lower end. The inlet receives tobacco from a feeding unit at the rate at which the tobacco particles leave the duct, and the device which withdraws tobacco from the duct by way of the outlet employs a hollow rotary drum-shaped carded conveyor whose carding travels past the outlet and removes tobacco which normally descends by gravity. In order to assist the gravitational descent of tobacco in the duct, the conveyor has a suction chamber and suction ports extending radially through the conveyor. The suction chamber is connected with a suction generating device, and the chamber accommodates a valve serving to connect the suction chamber with those ports which advance past the outlet so that the ports tend to advance the column of tobacco in the duct downwardly and into the range of the carding at the periphery of the conveyor. This ensures uniform filling of the carding with tobacco particles. <IMAGE>

Title: Dynamic range control
Inventor: MCNALLY GUY WILLIAM WHITSEY
IPC: H03G3/20
Filed: 1983-09-21
Abstract: A dynamic range controller consists of a multiplier 14 controlled by a side chain 18 comprising: a level detector 20, a log circuit 22, a threshold subtractor 24, a non-linear circuit 26, a slope multiplier 28, and an antilog circuit 30. The level detector (Fig. 4) comprises a peak detector with separate attack and decay time constants, in which the decay time constant is itself dependent upon the output of an r.m.s. detector. The slope and threshold values vary such that two or more different threshold/slope factor pairs are used for different sections of the signal amplitude so that the device provides different DRC functions (limiter, compressor, expander, or noise gate) for the different amplitude sections (Fig. 6). A smoothing recursive filter (Fig. 9) may be included between the antilog circuit 30 and the multiplier 14, and has a time constant which varies as to whether the detector is in the attack or the recovery mode, this mode determination being made with a degree of hysteresis. The response time constant of the filter is about one-third of that of the level detector 20. <IMAGE>
Patent GB-2133597-A (GB)
Title: Temperature compensated logarithmic circuit
Inventor: GILBERT BARRIE
IPC: G06G7/24
Filed: 1983-12-16
Abstract: A log-amp or log-ratio circuit is disclosed for producing a temperature- independent output signal corresponding to the logarithm of the ratio of a pair of input currents I1 and I2. The basic logarithm function is generated by a pair of matched transistors (Q1, Q2) connected to establish a pair of opposed P-N junctions through which the respective input currents flow. Temperature compensation is effected by a circuit including a pair of transistors (Q3, Q4) connected to establish a second pair of opposed P-N junctions which receive a PTAT (proportional-to- absolute temperature) current split between the junctions in accordance with a modulation factor x proportional to the desired logarithmic function. The temperature-induced signal variations produced by the PTAT current source are equal and opposite to the temperature- induced signal variations produced in the first pair of P-N junctions. Thus, circuit analysis yields the following equation from which the factor kT/q, common to all terms, has been cancelled:-  InI1/Is - InI2/Is = x Thus, x is directly proportional to the desired ratio. It is evaluated by means of the current-mirror circuit comprising Q5, Q6 connected to constant current source IR. It can be shown that the output voltage E is proportional to the desired ratio. <IMAGE>
