Title: Improvements in or relating to fuzes for projectiles
IPC: F42C5/02
Filed: 1941-09-22
Abstract: 579,921. Projectile fuzes. BLACKMAN, W., and POOLE, H. J. Sept. 22, 1941, No. 12254. [Class 9 (i)] Relates to arming devices for the fuzes of rocket projectiles (such projectiles having a low initial acceleration and little spin) of the kind actuated by air pressure developed when the rocket is in flight. According to the invention, the arming device, such as a conical diaphragm 17, is one which moves suddenly or collapses when the air pressure transmitted through passages 31, 32, 24 exceeds a predetermined value. In the form shown, a conical or dished diaphragm 17 of sheet copper or aluminium is attached at its centre to a sliding and preferably weighted striker pin 19, the rim of the diaphragm being fixed between the nose 13 and body 14 of the fuze cap. The air pressure is exerted in the chamber 16 above the diaphragm and the pressure of air on the underside of the diaphragm is reduced by providing an air passage leading to an opening at the outside of the projectile where a cowl may be placed. On collapse of the diaphragm, the striker fires a detonator cap 20 to initiate the action of a time-ring combustion fuze, or alternately, the pin 19 may release the geartrain of a clockwork time fuze or operate the first stage arming-switch of a proximity fuze of the photo-electric, radio or acoustic type.

Title: Improvements in and relating to road traffic or like signals or display signs
IPC: G08G1/095
Filed: 1936-04-30
Abstract: 453,412. Road signals for controlling traffic. KENT, A. F., Lee Moor, Plymouth. April 30, 1936, No. 12263. [Class 118 (ii)] [See also Group XVIII] Light is reflected by means of a moving parabolic mirror onto coloured windows to give red, amber and green signals. The unit described is weight-driven, the weight being lifted each time the unit is operated. Daylight or reflected light enters the casing through the top, passes between vertical screens 6, is reflected by the mirror or mirrors 3 and illuminates the lower green window 2. To operate the unit the link 11 is pulled by a pedestrian or a road pad so that the arm 8 carrying the spherical weight 13 is raised. When the arm is in its upper position, the weight rolls through the opening 14 into the chamber 16 in arm 17. The arm 17 is lowered, its movement being retarded by any suitable device, such as a dashpot, scape wheel, or air brake, and tilts the mirror 3 so that the reflected light illuminates the amber and then the red windows. When the arm 17 is in its lower position the weight 13 rolls out of the chamber 16 through the opening 18 into the chamber 12 allowing the arm 17 and the mirror to restore. Shields 19, 20 retain the weight 13 in openings 18 and 14 if either arm 8 or 17 is not in position to receive it. The arm 7 attached to the mirror passes across the amber and red windows before the signal changes to give a warning of the change. Supplementary windows 2 showing in different directions or indicating to pedestrians may be provided, the windows being illuminated by light reflected by tilting mirror 3 onto suitably arranged fixed mirrors. The unit may be used as a sign, the windows 2 being replaced by one long window or by a number of small windows bearing pictures, words or other characters. The mirror may be tilted by clockwork.

In a belt conveyer of the kind in which the belt is supported by a frame built up of sections, the longitudinals of which are supported by stools, the stools and longitudinals being connected by pins secured to the longitudinal members or to coupling plates connected to the stool members, co-operating with recesses in the other members, the coupling plates are provided with two or more pairs of recesses or pins, the distance between the recesses or pins of each pair differing from the distance between those of the other pair or pairs, the recesses or pins being so arranged on the plates and the plates being so mounted on the stools that the plates may each be turned top to bottom or reversed back to front or both, to enable a selected one of the pairs of recesses or pins to coact with the pins or recesses provided on the longitudinals, whereby adjustment may be made to the length of the conveyer frame. As shown in Fig. 1, longitudinals 1 bearing the cover plates of the lower run of the belt and the idler rollers of the upper run, are supported by bars 3 on stools 2 and connected thereto by pins 8 engaging the upper pair 6 of two pairs of recesses 6, 7 in a coupling plate 4. This plate is detachably mounted on the stool so that it can be turned top to bottom, having upper and lower holes 9 either one of which can be engaged over a stud 5 on the stool. The distance between the recesses 6, 6 is greater than the distance between the recesses 7, 7 so that if, for example, after the floor of a mine gallery has been levelled, the ends of the longitudinals have come closer together, the coupling plates are turned top to bottom to enable the pins 8 to engage in the recesses 7, 7. In a modification (Fig. 2, not shown) each coupling plate has pairs of pins at different spacings on opposite faces and at different levels of the plate. The longitudinals are provided with recesses and to make an adjustment in the length of the conveyer frame, the plates are turned top to bottom and their faces reversed. Alternatively the pins may be at the same level. Specifications 623,755 and 728,831 are referred to.

Title: Improvements in and relating to cathode ray oscilloscope time-base signal generatingcircuits
Inventor: HULLS LEONARD ROBIN
IPC: H03K6/00
Filed: 1954-04-30
Abstract: 770,013. Cathode-ray oscilloscopes; pulse circuits.. ENGLISH ELECTRIC CO., Ltd. April 29, 1955 [April 30, 1954], No. 12595/54. Classes 40(6) and 40(7) Relates to a cathode-ray oscilloscope for displaying periodic transient signals, e.g. for use in testing the ignition system of a multi-cylinder engine, in which a recurrent sawtooth waveform is applied to a slicing circuit which selects a portion of the sawtooth for use as the sweep voltage, the timing of the selected portion being controlled by an adjustable bias voltage v applied to the slicer. According to the present invention, the top and bottom slicing levels are determined by voltages V1 and V2, Fig. 3 (not shown), which together with the adjustable bias voltage V are derived from a D.C. voltage of amplitude equal to the peak amplitude of the sawtooth such that the timing of the timebase sweep and its duration expressed as fractions of the period of the sawtooth period are independent of fluctuations in the amplitude and frequency of the sawtooth. As shown the sawtooth is applied through a cathode follower 14 to (1) a peak rectifier 18 whose D.C. output is applied to a cathode follower 21 whose cathode load comprises a resistor 22 in parallel with a potentiometer 23 and (ii) the anodes of two diodes 25, 26 whose cathodes are connected to tappings 22a and 22b at voltages V1 and V2 respectively, the adjustable bias V provided by the slider of potentiometer 23 being applied to the anode of diodes 25 and 26 via resistors 24, 27 such that the peaks of the sawtooth of amplitude greater than V1 are clipped by diode 25 and the portions of the resultant clipped waveform of amplitude greater than V2 are passed by diodes 26 through capacitor 29 to an output terminal for use as the timebase sweep. The amplitude of the input or output waveforms. may be stabilized, e.g. as disclosed in Specification 765,557.

In a rotary duplicating machine for making prints on sheets, cards or the like from an original duplicating sheet held on the surface of a rotary printing, drum by a clamp or clamps, a printing device for producing a text additional to that of the duplicating sheet on the sheets, cards,or the like is either mounted on a clamp or mounted between two of the clamps. The printing device comprises a series of rollers each having a series of raised digits spaced around its periphery. In one form, Fig. 1, the rollers 1 are carried by a shaft 3 resiliently mounted in concave recesses in a series of holding members 2 extending across the printing drum 30. A spring-pressed pawl 5 engages a ratchet disc 6 attached to each roller. Each printing roller 1 and a corresponding indicating roller 8 can be rotated to expose a required digit by manual rotation of a carrier 13 on its shaft 12 so as to bring pawls 16, 17 into engagement with the ratchet discs 6, 11. The pawls 16, 17, which are pivoted at 20, 21 to the carrier 13, have their movements in one direction limited by stops 18, 19 but can move in. the opposite direction against springs when being freed from the ratchet discs. The carrier is slidable along the shaft 12 to act upon the required printing roller. A cylindrical inking pad 26 carried by a bell-crank lever 27 is brought up to rollers 1 when they pass it, by the action of a cam 29 on a roller 28 on the lever. A slotted tubular shield 26a partly surrounds the pad 26. In another form, Fig. 2, groups of printing rollers 37 are mounted between spaced holding plates 34 which are pivoted on a shaft 35, and held by springs 39 against an eccentric shaft 41 rotation of which moves the plates 34 to release the original duplicating sheet. Each group of rollers 37 is carried by a bracket 42 pivotable on a shaft 36 and acted on by a spring 44 so that an adjustable screw 45 is held against the shaft 35.
