Title: Pin-hole detector
IPC: G01N21/894
Filed: 1952-12-15
Abstract: 727,927. Photo-electric pin-hole detectors. UNITED STATES STEEL CORPORATION. Dec. 15, 1952 [March 18, 1952], No. 31759/52. Class 40 (3). In a photo-electric pin-hole detector in which sheets pass between a light beam on one side and a photo-electric cell on the other, the sheets then pass a second detector in which the illumination is from the other side. As shown, sheets from a pile 2 pass singly over a conveyer 6 between a light source 10 and photo-cell 12, and over a second conveyer 8 having a thickness gauge 20. At the end of conveyer 20 is a deflector 16 which is controlled by photo-cell 12 to pass sheets with a pin-hole to a bin 18. At the end of a further conveyer 24 is a deflector 28 operated by the thickness gauge. The plates are then carried up on a sloping conveyer 32 below which are permanent magnets 40 which hold the plates in contact with the conveyer, over an end pulley 36, the plates being held in contact by a further belt 48 and finally on the underside of belt 32 to which the plates are held by electromagnets 42. The plates are released when a photo-cell 52 detects their arrival at the lower end of the conveyer and de-energizes the electromagnets. Thus the plates fall on to conveyer 56 and are passed to a further pin-hole detector 66 with what was previously the trailing edge leading and inverted. This detector operates deflector 70, and a further switch-operated deflector 74 is provided to enable an operator to reject a plate after a visual inspection. Specifications 708,513 and 722,384 are referred to.

Title: Improvements in and relating to electrical control systems for electron beam heating devices
IPC: G05D23/27
Filed: 1969-06-25
Abstract: 1277098 Automatic control systems for electron beam heating MOSKOVSKY ORDENA LEMINA ENERGETICHESKY INSTITUT 25 June 1969 [27 June 1968] 31968/69 Heading G3R [Also in Division H2] The voltage across the anode and cathode of an electron beam heating device, which is supplied from a source providing a substantially constant beam current over a predetermined range of conductance values of the device, is stabilized by maintaining the conductance of the device at a substantially constant value through variation of the temperature of the cathode, the variation being effected by control of the power supply to the cathode in accordance with a signal dependent on a parameter representative of the conductance. The embodiment shown in Fig. 2 employs as a parameter the current through a probe 7 mounted close to the cathode of the electron beam heating device 1. The cathode power supply 4 is controlled through a unit 5 by a control unit 6 which includes a stabilized voltage supply 8 for the probe 7 and an element 9 to measure its current. Normally members 4, 5, 6 operate to maintain the conductance of the device 1 at a predetermined value, but should the conductance fall below a predetermined value the unit 6 actuates another unit 3 to switch off the constant current source 2. In Fig.3, the unit 6 includes a relay 10 responsive to a predetermined maximum voltage of the source 2 and a relay 11 responsive to a predetermined maximum current supplied to the cathode from the supply 4. If a decrease of conductance causes the voltage of source 2 to exceed the setting of relay 10, the unit 5 adjusts the supply 4 to restore the conductance to the desired value. If the conductance increases to cause the setting of relay 11 to be exceeded, the unit 5 again adjusts the supply 4 to restore the conductance. Should relays 10, 11 fail to do this, the source 2 is switched off by the unit 3. A timing element in relay 11 prevents switch-on of the source 2 at start-up until the supply 4 has brought the cathode up to its rated temperature. In a third embodiment, Fig. 4 (not shown) the unit 6 includes a photo-electric pyrometer responsive to the temperatures of the anode, the cathode and the article being processed in the device or to selected ones or combinations of those temperatures.

Abstract: 1441603 Road-traffic detection THOMSONCSF 5 July 1973 [7 July 1972] 32179/73 Heading G4Q Objects moving along a route are detected by localized-area detectors operable independently by a specific signal transmitted from a control centre to which the detector responses are sent. Detectors.-Figs. 2, 3. A given detector is addressed by a binary-coded signal decoded at 21 to modulate a transmitter 23 with a pulse; a vehicle causes the input to receiver 26 to rise above level V Fig. 3: when there is no coupling at all between aerials 24, 25 the receiver output is below level F and when there is vehicleabsent coupling that output is between levels F and V. The output of the receiver is encoded into the existing one of the three possible states and sent to the control station on line 12 of three-core cable 1, line 13 of which is for power supply. Optical, magnetic or electro-acoustic detectors may be employed. Control centre.-The control centre includes keyboard control (31, Fig. 4, not shown) for selection of detector address from a memory (32), or a timer for sequential detector interrogation. A processor determines the geographic location corresponding to an address and displays detector outputs (35) which show for the locations, the presence of a vehicle, or whether a detector is defective (corresponding to a level less than F, Fig. 3). Applications.-In addition to road traffic the invention may be applied to maritime or river traffic.

Title: Improvements in and relating to purification of fats
IPC: C11B3/06
Filed: 1960-09-20
Abstract: <PICT:0887885/III/1> <PICT:0887885/III/2> Fats are purified in a process in which the fat in a vacuum-dried water-free state is treated with concentrated phosphoric acid, preferably of at least 85% concentration, in an amount of 0,025-0,3% by volume of the fat at 60 DEG -90 DEG C. for at least 5 minutes, after which the fat, while still in its substantially water-free state is separated from any precipitate, suitably by filtration or by centrifuging, and wet-refined with alkali. Suitable fats for such treatment are hardened peanut, whale, or cottonseed oils, tallow or lard.  It is preferred that the contact time of the fat with the phosphoric acid does not exceed 30 minutes, and that during the acid treatment 0,01-0,03% by weight of the fat of a reducing agent, suitably sodium bisulphite, be present.  In a preferred embodiment, fat is passed by line 3 (see Fig. 1) to scalepan 2 of automatic weighing machine 1, and then passes by line 10 to spraying device 11 within container 4 which is maintained at about 6 mm. Hg pressure by evacuation through line 5.  The fat leaving sprayers 11 is vacuum-dried, and de-aerated and collects in tray 6 which is fitted with a thermostatically controlled steam coils 12 and agitator 13.  At intervals, the batch of fat which has been collected in tray 6 is discharged through drain 14 into tray 7 which also contains an agitator 22.  Phosphoric acid of at least 85% concentration is then added by line 18 from tank 17, and the mixture passed to tray 8 containing agitator 23 through drain 15 where the reaction is allowed to proceed for the required period. At the end of this time the mixture is passed through drain 16 to buffer tray 9 which contains floats 29 and 30 as well as agitator 24 and heating coil 21.  These floats 29 and 30 actuate programme apparatus 28, and so control the operation of valves 26, 27, and 19 and drains 14, 15 and 16.  The fat in tray 9 is pumped by pump 20 through line 31 to filter 32 (see Fig. 2).  At the start of filtration, however, the fat passes from line 31 by line 33 to tank 34 where it is mixed with a filter aid, e.g. kieselguhr.  This mixture is then passed by pump 35 back along line 33 and 31 to filter 32 where the aid is deposited on the filter supports, the fat passing by line 37 back along line 38 to tray 9 (Fig. 1).  The entire system is operated at low pressure, evacuation being achieved by line 36 connected to line 38.  When sufficient filter aid has been deposited on the supports, valves 33 and 39 are closed and the fat in line 31 passed directly to filter 32 which it leaves by line 37 and thence by line 40 to any suitable alkali refining treatment.
