Title: Apparatus for measuring very thin film thicknesses
IPC: E02F3/407
Filed: 1962-11-19
Abstract: 996, 777. Beta-back-scatter thickness gauges. BOEING CO. Nov. 19, 1962 [Nov.20, 1961], No. 43623/62. Heading G1A. [Also in Division H5] Apparatus for indicating or measuring the thickness of a coating on a specimen comprises a surface having an aperture against which the specimen abuts, means for directing radiation from a radio-active source through the aperture and means for detecting radiation back-scattered through the opening. #-radiation from a source 13 Fig. 1 is back-scattered to a Geiger tube 11 from a coated sample 17, direct irradiation of tube 11 being prevented by a glass shield 18. In a nodification for measuring the coating thickness of printed circuits, the aperture 16 is reduced to a slit slightly narrower than the printed circuit connections by plates 22 Fig. 2 of the material sold under the Registered trade mark "Plexiglas". The source which may be promethium 147 for measuring gold plating is electro-deposited from a PmCl 3  solution on the top surface of a copper wire 27 which is wedged between the-plates 22. The remainder of wire 27 is covered with lead foil 26. A mirror 23 is provided to align the printed circuit over the slit. The procedure is to measure the background count with no sample, then from the uncoated side of the dample and then from the coating. The per cent increase in scatter of the coating over the base material is coating count - base count/base count - background x 100 For a 10-60 copper coating on a phenolic base, thallium 204 is used as source and for a rhodium coating, carbon 14 is used. The apparatus is calibrated with a plurality of known samples.

Title: Signal level discrimination circuit
IPC: G06F7/02
Filed: 1974-10-09
Abstract: 1481730 Pulse shaping YOKOHAMA RUBBER CO Ltd 9 Oct 1974 [9 Oct 1973] 43821/74 Heading H3P Pulses are squared by a circuit in which a succession of digitally encoded samples are produced from an input analog signal and the difference between successive samples is compared with a preset value to determine whether there has been a change from a high level to a low level or vice versa. As described, the output of a camera tube reading marks on a wheel tyre is applied to an A/D converter 11 producing digitally encoded samples each of which is put into registers 12 and 13 and the preceding sample in register 12 is shifted on to register 14. The sample in register 13 is compared with preset maximum and minimum levels in a comparator 15. If the sample is either above the maximum or below the minimum respective signals from outputs 18 or 25 cause the output circuit 20 to inidicate white or black. The level of the last evaluated sample is always stored in memory 29. If the sample in register 13 lies between the maximum or minimum value, comparator 15 gives an output at 25 which causes an amount #V 0  to be added to or subtracted from the sample in register 13 according to whether the preceding sample was white or black. The resulting value in register 13 is compared with the preceding sample from register 14 and if the sample value has changed towards the other level by more than the amount #V 0 , a signal is applied to the appropriate one of gates 19, 23 to change the output of circuit 20.

Abstract: 1405703 Photographic flash control circuits ASAHI KOGAKU KOGYO KK 19 Sept 1973 [22 Sept 1972] 43989/73 Heading G2A A flash control circuit comprises a photoelectric element which receives flash-light reflected from the subject, an A.C. amplifier for amplifying the resulting output voltage, and means for transforming the amplified voltage into a current; the current being integrated and compared with a reference voltage to control termination of the flash. This circuit has a faster response at low light levels than circuits having D.C. amplifiers. As shown, closure of a switch SW 1  discharges a capacitor Cl through a flashtube FT1, the resulting transient being detected by a circuit R 5  C 3  R6 D2 which turns transistors TR 7  and TR6 off thereby enabling an integrating capacitor C2 to start charging. A photodiode PD causes a current ip to flow through a resistor R 1  and the voltage appearing across R 1  is amplified by an A.C. amplifier TR 1  TR2 having a gain A. A differential amplifier FET 1  FET2 TR3 TR4 produces a collector current in a transistor TRs equal to AipR 1 /R ASA , where RASA is set according to film sensitivity and/or diaphragm aperture. This current charges capacitor C 2  until a transistor TR 8  conducts, an element SCR is triggered and a stop tube FT2 is turned on. In Fig.3 (not shown) an SCR element is connected in series with the tube FT1 to terminate flash.

A method of erecting a multi-storey building includes the steps of forming the floors such as 1, 2, Fig. 1 (/), at ground level, raising same together as by hydraulic jacks 6, lifting posts 8 and rotary nuts driven by electric motors, placing temporary supports such as loadbearing shuttering 11 beneath the lowest floor, raising the remaining floors to the next level, erecting final supports for the lowest floor and then securing same to its supports and so on. The posts are themselves raised by the lifting devices after positioning of the temporary supports but for full details of lifting technique the Specification should be referred to. In a modification, Figs. 2a . . . 2m (not shown), the load bearing shuttering is positioned a small distance away from the threaded lifting parts which when raised rest on plain tubes. Concrete is poured through apertures into the shuttering to form the concrete columns the reinforcements of which extend through the apertures. In a further modification, Fig. 3 (f) a mobile crane together with precast concrete columns 70 and two-part temporary tower 55 are positioned on the roof 56. Two sections of a tower 55 are lowered through apertures in the floor and bolted together about the lifting post which is then raised and supported on beams 61 carried by the tower 55. Floors 51, 52 are again raised whereupon the column 70 is permanently positioned on to splice bars 58. The concrete columns may be replaced by steel stanchions. Separation of the floors is ensured by covering same with a thin sheet of polythene, paper, liquid wax, foundry parting powder or a resin-based parting compound.

T is a comparison matrix of a primitive polynomial g(x) of degree f=bm=the number of bits in each byte 3<K<2<SP>b</SP>, #=r(2<SP>f</SP>-1(/(2<SP>b</SP>-1), r is a positive integer prime to (2<SP>b</SP>-1) and I is an identity matrix. After use, e.g. transmission or storage and read-out on magnetic tape, pointers i, j, k to the bytes Z0<SP>1</SP>-Z14<SP>1</SP> in error and syndromes S0-S2 are generated, the latter by means of feedback shift registers. The pointers i, j and k are set to K when no errors are present and are set to indicate the number of the byte(s) or track(s) in error for the respective cases of one, two or three bytes in error. Since generation of an error pointer may be due to a circuit fault, zero syndrome status overrides the error pointers. Non-zero syndromes may also be used to identify a track in error when no corresponding error pointer is generated. In the correction process a suitably programmed computer can be used to solve the simultaneous equations linking S0-S2, i, j, k and error patterns el-e3 and to correct the errors by modulo 2 addition of the identified erroneous byte(s) Z<SP>1</SP>i, Z<SP>1</SP>j, Z<SP>1</SP>k with the appropriate error pattern el-e3.
