Title: Improvements in or relating to tile making machines
IPC: B28B5/02
Filed: 1948-01-21
Abstract: 652,416. Moulding tiles. PEGSON, Ltd., and DAVIDSON, D. J. Jan. 21, 1948, No. 1836. [Class 87 (ii)] Pallets P are carried by a combined conveyer and driving mechanism 1, Fig. 1, beneath a tile moulding unit 2 where material such as concrete, mortar and like cementitious materials, and clay &c., is moulded by a roller 3 into a shaped ribbon R which is supported on the travelling pallets and carried beneath a guillotine 4, Fig. 3, to be cut transversely into individual tiles. The guillotine, Fig. 5, comprises a knife 8 vertically reciprocable to the stream of material, and has associated therewith a punch or punches 9 for forming nail holes. The guillotine has a horizontal crosshead 10 beneath which is yieldingly mounted a parting knife bracket 11 carried by spring- controlled plungers 12 vertically movable within bearings 13. The knife 8 is adjustably attached by screws 14 to the bracket 11 and the back of the latter has a bearing 15 for a punch 9 also adjustably spring controlled. In a modification described in the Provisional Specification the knife is attached to the back of the bracket and the punch to the front. The cross-head 10 is slidably mounted and controlled by springs 25 upon guide members 23 connected to or integral with levers 24 fulcrumed on a bar 27, bolted to the members 29 of the machine frame. A tie-bar 30, and a bar 31 having a knife cleaning attachment, form a rectangular supporting frame for the cross-head 10. The knife cleaning arrangement, Fig. 7 (not shown), consists of spring-pressed felt-lined bars 31, 33 between which the knife reciprocates. Extending through and guided by slotted members 55 are the fulcrumed levers 24 oscillated by rods 40 and cranks 41 fixed to a countershaft 42 continuously driven by means of sprocket-wheel 45 and chain 46. The knife and punch are actuated by means of downwardly extending links 47 pivoted at 22, and a lever 48 fulcrumed at 52, the lever 48 having bifurcated limbs 48a and a cam follower 49 arranged in the path of a roller 50 on an angularly adjustable cam disc 51 mounted upon the countershaft. Upon rotation of the countershaft the levers 24 are oscillated to move the cross-head 10 to and fro in a slightly arcuate path above the ribbon of material, and at the same time the knife and punch are vertically reciprocated under the control of springs 25. The cam disc 51 is so adjusted that the operative cutting stroke of the knife takes place when the levers 24 are substantially vertically disposed on the line 1, Fig. 3, at the instant the knife is travelling at the same speed as the ribbon. Provision of any suitable character may be made to vary the knife stroke which is so timed that the knife comes down between the adjoining pallets. The colour box 5 is reciprocated automatically under the control of springs 56 from the cam disc 51 through intermediate connections timed in relation with the guillotine. A roller 6 presses a topping mixture of sand, cement and colour into the top face of the tiles and a rotary cutter 7 trims the tiles flush with the pallet edges.

Title: X-ray stereoscopic photographic device
IPC: A61B6/02
Filed: 1965-05-11
Abstract: 1,097,928. X-ray apparatus. T. TOKUYAMA. May 11, 1965 [May 13. 1964], No. 19875/65. Heading H5R. Apparatus for stereoscopic radiology comprises a cassette 5 containing a screen of X-ray opaque material having a number of slots in or against which slots is disposed fluorescent material, and a film 4 disposed in close contact with the screen, the screen and film being relatively movable to one another in directions parallel to their planes but perpendicular to the length of the strips, and the fluorescent material transforming X-rays incident on it to visible light by which the film is exposed. The screen or the film may be arranged to be connected to the X-ray tube mounting so that they undergo coupled movement either side of an object 6, the tube moving parallel to the direction of movement of the screen or film. The movement may be continuous, the screen or film moving through one strip pitch and a continuous exposure being made. Alternatively, the X-ray tube may move in a circular motion with respect to the object, or the object move circularly with the tube fixed, while the screen and film move relatively to one another rectilinearly. An exposed film can be viewed to give a stereoscopic image by the use of a suitable lenticular plate (Fig. 2, not shown). The screen may be an X-ray opaque plate, having a number of slots filled with fluorescent material, or a very thin sheet grating with an intensifying screen bonded to it. The film in the cassette can be exposed for stereoscopic work from either side since the film is sensitive only to visible light and not to X-rays.

Title: Apparatus for and a method of improving the sharpness of images
IPC: G02B17/06
Filed: 1963-01-16
Abstract: 1,037,831. Optical apparatus. L.STRAUB. Jan. 16, 1963 [March 22, 1962], No.1905/63. Heading G2J. Image sharpness is improved by reducing diffraction effects at the edges of apertures or of objects under observation by superimposing a coherent wave train on a diffracted wave close to the origin thereof, the phase difference between the diffracted wave and the wave train being equal to an odd multiple of one half of the wavelength of the diffracted wave. As shown a parabolic mirror 1 forms an imaging system and its edge 2 produces a diffraction effect which is reduced by providing annular mirror 3 which provides a reflected wave at edge 2 with the required phase difference. The width b of mirror 3 may be from 2# - 5# whilst d may be from # - 5#/ 12  In a modification, Fig. 2, (not shown), an annular member 5 is spaced in front of edge 2 and provides a diffracted wave to counteract the effect of that produced by edge 2.

Filed: 1976-01-20
Abstract: 1497961 Burner control systems HONEYWELL Inc 20 Jan 1976 [13 Feb 1975] 02102/76 Heading F4T [Also in Division F2] A burner control valve assembly comprises valves 13, 26 controlling the gas supply to main and pilot burners respectively, and a manually operable actuator 30 which upon a first movement causes the pilot valve 26 to open and upon a subsequent movement causes the main valve 13 to open if a device included in the assembly has operated in response to the presence of a flame at the pilot burner; depression of knob 30, and with it shaft 25, causes valve member 32 to be moved away from its seat 33 to admit gas to the pilot burner and causes a latch 43 pivoted to the shaft 25 to depress a member 52 to urge an armature 51 against an electromagnet 50; when a flame at the pilot burner is sensed by a thermocouple the electromagnet 50 is energized and retains the armature 51, so that if the knob 30 is released the latch no longer bears on the member 52 but is pivoted by a spring 45 to engage a projection 21 of the closure member of the main valve 13, so that as the shaft 25 rises the main valve is opened. If the knob 30 is released before ignition of the pilot burner, or if the flame is subsequently extinguished, the magnet 50 is de-energized and member 52 rises to engage the latch 43 and pivot it out of engagement with the projection 21 so that the valve 13 is closed by spring 16. To extinguish the burner the knob 30 is rotated, causing the latch 43 to release the projection 21; if the knob is then depressed before the member 52 has returned from its depressed position the latch 43 engages an abutment 71 and is pivoted so that it cannot engage the projection 21, so that the burner cannot be reignited until the thermocouple has cooled sufficiently to de-energize the magnet 50.

Abstract: 304,693. Siemens - Schuckertwerkes Akt.-Ges. Jan. 24, 1928, [Convention date]. Systems depending on static transformers; regulation, automatic.-Arrangements for limiting the power transmitted from one network 10, Fig. 10, to a second network 11 of equal frequency comprise a transformer 1 with its primary and secondary connected respectively to the networks 10, 11 and with the secondary carried by a rotatable shaft 2 coupled to an electric torque motor producing an adjustable, unidirectional torque on the secondary. As the power transmitted rises, the secondary turns against the torque of the motor 4 and keeps this power constant. The torque motor may comprise relatively rotatable direct-current coils as shown or a directcurrent dynamo-electric machine, the excitation being adjusted to adjust the torque and so the power transmitted by the transformer 1. Overloads on the network 11 may be taken by generators on this network. A standard transformer may be connected between the networks 10, 11 in parallel to the transformer 1 so as to take peak loads of the consumer's network 11. The arrangement is applicable to the local regulation of the loads in parallel-connected conductors of different dimensions. A prior arrangement is referred to in which a locking device for the secondary of the transformer is released when the power rises, the secondary thereon turning into the position of zero transmission. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the application of the arrangement to the automatic distribution of load in a system with main and auxiliary powerstations. This subject-matter does not appear in the Specification as accepted.

Abstract: 113,323. Chappell, C. A. Feb. 20, 1917. Mines, marine.-Relates to mines discharged in the form' of projectiles adapted to break up into the component parts of a floating or anchored mine after striking water, firing contact arms being at the same time extended to the armed position. According to the invention, the arms are mounted upon spindles carrying ears which act as detents to the spring strikers. In the form shown in Fig. 1, the explosive charge a and the buoyancy chamber b are provided with a loose cap c completing the shape of the projectile. The cap is loosely fitted and falls off when the projectile comes to rest after striking water, and the mine floats about freely; before use, the cap is locked in place by a locking-device which is unfastened by hand. When the cap falls off, ringed arms m are released and are swung out by springs or by floats attached to them. And when these arms are struck by a passing ship, they rotate spindles and thereby withdraw detents h from beneath spring strikers d, which fire percussion. caps g. In modifications, (1) the mine is supported by one or more floating lines or is connected by a line to a float or to the cap c or by lines to both these, the cap c acting as a mooring; (2) the mine is connected to a line which rests partly on the bottom of the sea and holds the mine at a given depth depending upon the buoyancy of the mine as determined by the capacity of the chamber b which may then be made adjustable; (3) the mooring line is attached to a spring bolt on the mine and this bolt is conrected by lines to eccentrics about the pivots of the arms m, so that these arms are swung out by the tension of the mooring line, and if the mine breaks away from its mooring, the arms fold back to the safe position; (4) the cap c is provided with external ribs and is prevented from rotating relatively to the mine while still free to fall off, this being intended to check the rotation of the projectile when it strikes water after discharge from a rifled gun; (5) means are provided for exploding or disarming the mine after a given time; (6) an explosive charge is provided for expelling the cap when the projectile strikes water
