Abstract: 1,258,117. Phase locked oscillators; monostable circuits. DECCA Ltd. 20 July, 1970 [14 Oct., 1969], No. 50542/69. Headings H3A and H3T.  A phase locked oscillator comprises an oscillator unit 12 having an output changeable between two frequencies, a phase comparator 16 and an integrator 20, an arrangement 22, 23 and 25 for producing an oscillator control pulse signal whose pulse period is greater than the cycle period of the oscillator output and having a pulse duration linearly proportional to the amplitude of the integrated phase error signal and a further arrangement 13 for changing the oscillator output between its two frequencies so that the average frequency is maintained at the required value for phase lock e.g. for an intermittent or noisy signal. The oscillator control signal may have a rectangular or triangular waveform with a repetition period over 10 times the oscillator cycle period and the overall phase shift is less than 30. The frequency control pulses may be produced by a linear timing generator (Fig. 3) comprising a constant current generator (34) charging a capacitor (33) and a monostable pulse generator (31, 32), the two generators being controlled by clock pulses (at 35) from a source 23 determining the pulse repetition period. An electronic switch comprising an F.E.T. (36) is provided for switching a capacitor in the oscillator circuit. The timing generator comprises a constant current generator 34 charging a capacitor 33 to a magnitude dependent on input amplitude from transistor 30 or to a fixed voltage at a current rate dependent on input amplitude. A clock pulse applied at 35 initiates charging and determines the pulse repetition period of the monostable circuit 31, 32. The pulse duration and hence the mark-space ratio are dependent on the input amplitude 30. The output pulse is used to switch capacitor 37 in or out of circuit by an F.E.T. switch 36.

Abstract: 1,258,247. Image intensifier tubes. ENGLISH ELECTRIC VALVE CO. Ltd. 5 May, 1969 [18 June, 1968], No. 28874/68. Heading HID. A photocathode for an image intensifier to be used as an electronic .shutter in high-speed photography, is deposited on a metal mesh substrate preferably having 750-1000 square holes per linear inch. In one method of manufacture a copper mesh is pressed into a glass substrate by optically polished carbon blocks whilst the glass is heated (e.g. to 900‹ C.) in a reducing atmosphere. In another method a fibre optics face plate is coated with a photo-resist layer which is exposed to light through the plate; after developing and etching a film of metal such as gold/palladium alloy or silver or aluminium is sputtered or evaporated on and polished to leave the metal only in the grooves formed by the etching. In another method the grooves are formed on an optically flat surface by scribing with a diamond or by a photo-resist method, followed by metal deposition as in the previous method. A further method comprises applying a photo-resist to a chromium covered surface to expose parts of the chromium surface which are then etched away. The resulting transverse resistance may be less than 1 ohm per square and the cathode sensitivity may be about 120 ÁA/L. Reference has been directed by the Comptroller to Specification 1,217,477.

Abstract: 1,265,033. Catheters. AMERICAN HOSPITAL SUPPLY CORP. 1 Oct., 1969 [21 Nov., 1968], No. 48182/69. Heading A5R. A surgical catheter or probe comprises a flexible transparent insertion tube 1, a flexible sleeve 4, disposed inside the bore of the insertion tube 1 and having an end portion over the end 2 of the tube 1, and being secured to a rigid guide sleeve 6 which surrounds the end 2 of tube 1 in its normal position. The guide sleeve 6 consists of a body engaging shield 7 which secures the rubber sleeve 4 on a tubular section 8 having a finger grip 17 and a second section 9 having a pair of diametrically opposed slots 11 and 12, through which a handle 13 protrudes, the end of the guide sleeve 6 being sealed by a cap 10, allowing the insertion tube 1 to pass through it. The handle 13 is constructed of a rigid tubular segment 14, with a C-shaped crosssection, fixed around the tube 1 and a pair of thumb pads 15, 16 mounted thereon, extend through the slots 11 and 12. To operate, the insertion tube is projected from the guide sleeve 6 by moving the thumb pads 15, 16 towards the finger flange 17 and forces the sleeve 4, against the sides of a body passage e.g. the urethra, until the insertion tube end 2 extends beyond the sleeve 4. Urine can then flow through the channel formed by the insertion tube I, and out through an adaptor 18 joined to its far end. Alternatively a string (22) Fig. 7, can be joined to the sac (19) at the end (25) which has an aperture (27) and during application the sac (19) is not fully removed from the insertion tube 1. The sac (19) is retracted within the insertion tube 1 by the string for determination of bacteria along the body passage. The insertion tube 1 may be curved, Fig. 8 not shown, to facilitate the passage of the tube 1 through the urethra.

Abstract: 1,265,284. Photographic apparatus. POLAROID CORP. Oct.15, 1970 [Oct.21, 1969], No.49090/70. Heading G2A. In a camera holding a stack of film units, the foremost being in the exposure position, means are provided for engaging a film unit in the exposure position and moving it therefrom after the shutter has been released. When the shutter has been re-tensioned, the film-engaging means is disabled by being moved out of engagement with the film until a further exposure has been made. In the example shown, the film units are of the type having a pod containing processing liquid which is ruptured on being passed between rollers 62 and the liquid spread between two sheets of the film unit. A motor-driven gear 84 engages a gear 86 on the upper roller 62 which engages a gear 88 on the lower roller. Thus when a film unit is drawn into the nip between the rollers, they continue to draw the sheet between them. Gear 84 also meshes, via an idler gear 90, with a gear 92 to which a link member 96 is pivoted at 100, The other end of member 96 is pivoted at 98 to a block member 68 which can slide within a U-shaped frame section 70. Also pivoted to member 68 at 72 is an arm 76 having an extension 78 and a downwardly flanged member 80, the latter being shaped and pointed so that it can enter through a slot in the container holding the film units and engage an aperture in the film unit. Thus as gear 92 rotates anticlockwise, as shown in Fig.4, a reciprocating movement is imparted to arm 76, and as it moves to the right the member 80 engages and moves a film unit towards the rollers 62. An arm 102 is pivoted at 104 to the main housing and has at its other end an outward flange 106. A resilient member 108 is attached to arm 102, and has a U-shaped end 110 which abuts against the end 120 of a lever 122. A shutter blade 116 is also pivoted at 104, and has a tab 118 positioned to engage flange 106. When the shutter blade 116 is in the tensioned position, it occupies the position shown in Fig.6. Tab 118 engages against flange 106 and pushes lever 102 downwards, so that the U-end 110 pushes the lever end 120 down into the position shown in full lines. The lever 112 is positioned by two pins 124, and in the pushed-down position of Fig.6 the other end of lever 122 engages under arm 78 and lifts it up, so that member 80 is lifted out of engagement with a film unit. Thus although member 96 is still executing its reciprocating movement, it has no effect on the film. When the shutter release is actuated, shutter 116 pivots anticlockwise, out of contact with arm 102, so that the end 120 of lever 122 can rise to the position shown in dotted lines Fig. 6 under the weight of arm 76 on its other end. Member 80 now moves downwards, so that it can enter into engagement with a film unit, and, as lever 96 carries out its reciprocating movement, the unit is moved into the nip of the rollers 62. When the shutter is tensioned again, member 80 is once more disabled.
