[Also in Group XXXV] The Specification contains the same subjectmatter as Specification 860,227, wherein the control exerted by a first variable is over-ridden by the control exerted by a second variable when the second variable is outside a predetermined range of values. The limiting circuit 80 comprises a biased rectifier bridge 90 to which is applied, in the non- conducting direction, a D.C. potential difference developed across a resistor 95. The voltage developed by the resistor bridge 82 is applied to the rectifier bridge 90 such that a current will flow in the reactor windings 44 only when a thermistor 81 in the bridge 82 has been affected by temperature.sufficiently to provide a voltage output from the bridge 82 which when applied to the rectifier bridge 90 overcomes the D.C. bias thereon whereby a voltage appears on the output terminals of the circuit 80. In a further embodiment the reactor windings 44 are placed in the D.C. biasing circuit. Specification 860,228 also is referred to.

Abstract: 1,151,134. Charging and discharging metal heating furnaces. FUEL FURNACES Ltd. 27 Dec., 1967 [28 Sept., 1966], No. 43339/66. Heading F4B. A continuous furnace for heating the ends of metal pins, rods &c. has a rotatable door 11 formed with an annular system of workpiecereceiving sleeves 13 each associated with a peripheral finger 12, a feed ram 38 pushing workpieces from a hopper 31 singly and in turn into a sleeve 13, and a discharge ram 39 pushing treated pins through into the furnace on to a discharge shoot 43 leading to an external table 45. The door is carried by a stub axle journalled in a bearing block 15 carried between horizontal beams 16, said axle also carrying a gear-wheel 18 meshing with a gear-wheel 19 on a shaft 20 supporting a rotary pocketed drum receiving the workpieces below the hopper 31. The drum feeds a die trough located in line with the sleeves 13 and is supported from the bearing block 15 by a bracket comprising plates 22, 23 and 25. The door is rotated in angular steps equal to the angular pitch of the fingers 12 by an electric motor 33 through reduction gearing 34 and a cam disc 35 with roller 36. The gearwheels 18 and 19 are so related that each of these angular steps causes a workpiece to be deposited in front of the ram 38 ready to be pushed into a sleeve 13. A striker on cam disc 35 operates hydraulic motors controlling rams 38 and 39 and limit switches on both motors ensure that the drive motor 33 cannot be restarted until both rams have performed their return stroke. The furnace is mounted on wheels on end horizontal girders 5 of a girder framework 2-5, and is heated by a burner extending through a port 42. A shoot 44 carries away workpieces accidentally pushed into the furnace by feed ram 38. The length of rams 38, 39 can be varied to suit the workpiece lengths.

Title: Multiplexing apparatus

Filed: 1971-09-17
Abstract: 1361074 Speech transmission systems ELECTRONIC COMMUNICATIONS Inc 17 Sept 1971 [30 Oct 1970] 43570/71 Heading G4H In a speech multiplexing system, preferably utilizing delta modulation, the sampling rate of the individual speech inputs is rendered dependent upon the number active at the start of a sampling interval. Speech inputs are each fed to a corresponding #-# A/D converter which is associated with a threshold logic device to provide an indication as to the activity of the related input, this indication being taken to set a flip-flop related to a corresponding stage of a ring counter comprising a series of flip-flops to remove the stage from the series if the source is inactive. The beginning of a sampling interval is defined by a clock pulse adapted to cause read in from the threshold devices and to set a "low" state into the first flip-flop of the series whose source is active. The counter is then clocked during the interval so that the "low" state is moved through all the stages with active inputs in a cyclic fashion to clock the relevant A/D converters in turn. Read-in from the threshold devices is effected, e.g. every 1 ms. The multiplexed data from the converters plus synchronizing and format data is transmitted using conventional apparatus to a receiver containing a clock synchronizer adapted to respond to call words in the transmission, and a distributer in addition to a similar ring counter providing outputs in a corresponding way as the first counter, to a plurality of D/A converters. Details of the multiplexing process are not described. Thus the sampling rate of any one source, whilst it is active, is altered at each 1 ms. interval. It is stated that this is sufficiently rapid to achieve an averaging effect in the human ear.
