Title: Sensitive Silver Halide Photographic Materials
Inventor: RIDGWAY MICHAEL
IPC: G03C1/485
Filed: 1965-12-16
Abstract: 1,178,683. Photographic silver halide materials. KODAK Ltd. March 16, 1967 [Dec. 16, 1965], No.53382/65. Heading G2C. A photographic silver halide material incorporates a layer of a non-chemically sensitized emulsion containing a thiourea sulphur sensitizer which chemically sensitizes the emulsion on raising the pH. The sulphur sensitizer may be added in solution in a gelatine gel to a molten non- chemically sensitized emulsion and the resulting emulsion coated before any digestion can take place. The photographic material obtained is comparitively insensitive but can be sensitized in a short time, e.g. 10 seconds, by raising the pH by bathing in water or an aqueous solution of sodium carbonate and can then be exposed and processed in the usual way. Sulphur sensitizers specified are thiourea, allylthiourea, s-diethylthiourea, phenylthiourea and s-diphenylthiourea. Gold compounds such as sodium aurous thiosulphate may also be added. When the silver halide emulsion is an internal latent image emulsion containing a sulphur sensitizer as above, a reversal image may be obtained using a process similar to that of Specification 581, 773 by exposing the material image-wise to form an internal latent image, raising the pH to sensitize the surfaces of the silver halide grains, exposing overall and developing in a surface developer to obtain a reversed or positive image.

Filed: 1976-12-23
Abstract: 1535449 IC engine igniting timing systems MOTOROLA Inc 23 Dec 1976 [20 Jan 1976] 53740/76 Heading F1B An I.C. engine ignition timing circuit comprises a sensor generating an input signal 52 having alternate equal or unequal positive and negative half cycles each of which corresponds to a predetermined amount of angular rotation of the engine, there being produced, after each commencement 52a of a cycle, a signal 62 having a slope initially equal to k, but changing successively to k 2  and k 3  after respective time intervals T 1  and T2 if the engine speed is such that these time intervals elapse during the first half of the cycle, the slope changing to a negative value k 4  at the end of the half cycle whereby the signal 62 returns to zero value at a time T 4 . Ignition occurs at the instant T4, i.e., at an advance angle α, unless the engine speed is so low that an interval T 3  elapses during the half cycle, in which case the advancing pulse 65a is suppressed and ignition then occurs at the commencement To of the next cycle, i.e., with zero advance. A sensor sensing the intake manifold vacuum reduces each slope k 1 , k 2 , k 3  by the same amount, thereby increasing the advance angle.

Abstract: 1,214,504. Automatic mixing control for grinders. WESTINGHOUSE ELECTRIC CORP. Nov.27, 1967 [Dec.14, 1966], No.53745/67. Heading G3R. A grinding device is supplied with an input slurry containing the material to be ground and with new material, the supply of which is automatically controlled by a computer to maintain a predetermined relationship between the two supplies of material, the computer being fed with signals respectively representative of the density of the input slurry, of the density of the mixture of input slurry and new material and of the flow of slurry to the grinding device. In the described embodiment, the output of a grinder 10 is passed to a cyclone classifier 12 whose output 14 contains particles under a desired size and whose output 16 contains the oversize particles in a slurry which is fed to a mixer 20 also supplied with new material W from a conveyer 24 and with water F2 via a valve 34. The resulting mixture is then fed to the grinder 10 for repetition of the cycle. The valve 34 is controlled to maintain the density D2 of the output from the mixer 20 at a desired value. The computer 40 receives signals D1, D2, F2 and W and uses these to calculate, from known equations, the value of F1 (the flow of slurry from the classifier 12) and from this the value of S1 (the flow of solid material in the slurry from the classifier 12). The computer then varies W to maintain the quantity (S1+W) constant. Alternatively the flow F1 can be measured using a magnetic flow device and the member 26 can be omitted. The computer then calculates W and again calculates S1 to maintain S1+W constant.

Title: Beam intensity control system
IPC: G11B7/09
Filed: 1967-11-27
Abstract: 1,201,176. Automatic control for electron beam data recording systems. INTERNATIONAL BUSINESS MACHINES CORP. Nov.27, 1967 [Dec.21, 1966], No.53759/67. Heading G3R. The intensity of an electron beam striking the memory element 9 of a data recording system, is automatically maintained at a predetermined value by detecting the intensity at the element 9 to produce an electrical signal representative thereof, comparing this signal with a reference signal in a differential amplifier 39 and using the error signal to adjust the control current in the coil of an electromagnetic lens 15a, such adjustment altering the beam diameter at an aperture 28a to vary the number of electrons passing therethrough. As shown, a beam detector 37 is placed adjacent the element 9 and comprises a P/N junction having an impedance proportional to the intensity of the beam, which is made to intermittently strike the detector 37 as it scans across the element 9, by providing the latter with a series of opaque lines 41 perpendicular to the scanning direction and forming a series of adjacent and alternately positioned opaque and transparent portions. This produces an A.C. signal superimposed on a constant current through the detector and having a peak value proportional to the beam intensity, the combined signal being fed to a level detector 38 which produces a D.C. output signal representative of the peak value. After comparison of this output with a reference signal 46 representative of desired beam intensity, the error signal from amplifier 39 is fed to an analog storage device 48 which comprises a field effect transistor whose bias voltage is supplied by a large value capacitor charged by the error signal, so that a signal is stored until another is received from the amplifier 39. Thereafter, the signal controls the driver 49 of the coil of lens 15a to vary its magnification and hence the diameter of the beam. To prevent this change in magnification from affecting the overall functioning of the beam generating device 8, the signal from driver 49 is fed to the driver 55 of another lens 15 in such a manner that the magnification of the latter is changed in proportion but oppositely to the change in magnification of the lens 15a. The construction of the electron beam generator 8 is described, Figs.1 and 2 (not shown). Application of the invention to control a laser beam generator is envisaged.

Title: Improvements in and relating to Camera Shutter Arrangements.
IPC: G03B9/14
Filed: 1967-12-13
Abstract: 1,167,978. Camera shutters. RICOH K.K. Dec.13, 1967 [Dec.17, 1966], No.56552/67. Heading G2A. A shutter for a single lens reflex camera has means for synchronizing its operation with a flash circuit. The shutter assembly comprises three parts, an arcuate member (I), the shutter itself (II), and a ring member (III), mounted on abase-plate lying between I and II. Arcuate member I is pivoted at one end to the base-plate, and urged anticlockwise by a spring 2. It is shown in the "shutter tensioned" position in Fig. 1, and held thus by an arm 3 which latches in front of a lug Ia of member I. A shutter-operating member 4 pivots on an axis 5, and is spring-urged anti-clockwise. Member 4 carries an elongated pin 4c which passes through slots IIa in the shutter blades II, and extends as far as ring III, where it abuts against a cam portion IIIb of ring III. Mounted adjacent cam IIIb is a resilient electrical contact 8, biased towards the cam but held away from it by an insulator 8a. Contact 8 and pin 4c form the contacts which complete the flash circuit, but are separated in the position of Fig.1 (and Fig. 2 not shown). The shutter blades II are normally open, and the reflex mirror (not shown) in the "viewing" position. When the shutter release is actuated, ring III rotates anti-clockwise until cam IIIb comes up against a fixed stop 6. Pin 4c rolls down the cam surface, and its movement causes the shutter blades II to close. Blade 8 moves inwards, but is still out of contact with pin 4c. A pin 7 on ring III causes the mirror to move out of the light path, which unlatches arm 3 from lug Ia, so allowing member I to rotate anti-clockwise until a lug Ic thereon strikes a projection 4b of member 4. Member 4, and hence pin 4c, is thus caused to rotate clockwise, against its bias, which opens the shutter blades again, and also brings pin 4c against contact 8, so closing the flash circuit. A further lug Ib on a member I now strikes a projection 4a on member 4, causing it, in conjunction with its own spring-loading, to rotate anti-clockwise, so that pin 4c moves to close the shutter blades again. The reflex mirror is restored to its reflecting position by mechanism (not shown), so that ring III, and hence pin 4c, is brought back once more to the position of Fig.1, so opening the shutter again. When the film is wound on for the next exposure, it actuates means which push up an arm Id of member I, until that is also brought back to the initial position of Fig. 1.

Abstract: 1,154,398. Pipe couplings. C. K. WALTHER, [trading as CARL KURT WALTHER]. 15 Dec., 1967 [17 Dec., 1966], No. 57113/67. Heading F2G. A hose pipe coupling of the type wherein a spigot 1, having valve 3 biased to the closed position by a spring 2, is locked in a socket by balls 6 controlled by a spring-loaded locking sleeve 7 carried on the socket, comprises a socket constituted by two relatively displaceable socket parts 8 and 12, which define a fluid flow path 26, 26<SP>1</SP> for the passage of a flushing fluid to flush out the socket in one relative disposition of the socket parts prior to hollow mandrel 12<SP>1</SP> of the socket part 12 engaging and opening the spigot valve, and a catch device formed by a spring-loaded pin 11, which is carried by the socket part 8 and which is actuated by the socket part 12 during relative movement between the socket parts to prevent movement of the locking sleeve from the locked position. After initial locking of the spigot in the socket by engagement of the balls 6 in a recess 5 in the spigot, socket part 8 is rotated relative to socket part 12 so that, by virtue of their threaded engagement 13, socket part 12 is axially advanced towards the spigot. During this movement, the inclined end 21 of the socket part 12 engages the pin 11 and urges it outwards to prevent movement of the sleeve 7 from the locked position. In addition, a shoulder 22 on the socket part 12 lifts a spring-loaded valve 18 mounted on the mandrel portion 12<SP>1</SP> from its seat 19 on the socket part 8. A spring-loaded latch 24 then engages the socket part 8 to define a flushing position. In this position, the forward end of the mandrel portion 12<SP>1</SP> has not engaged the spigot valve 3. Flushing fluid may then be passed through port 14, past check valve 15, along passages 26, 27, 26<SP>1</SP>, and out through port 29. After flushing, the socket parts 8 and 12 are relatively rotated, subsequently to withdrawing latch 24, until the end 20 of the mandrel portion 12<SP>1</SP> engages and opens the spigot valve. Fluid may then be passed through the coupling.
