Title: Fishing device
IPC: A01K97/12
Filed: 1949-09-23
Abstract: 662,602. Automatic striking devices for fishing. SWAN, J. A. Sept. 23, 1949, No. 23050/49. Class 48 In a device for automatically hooking fish comprising a strike rod rotated by spring means and released by the movement of the fishing line, the torque exerted by the spring means is predetermined at the set position of the rod and this predetermined torque is less than the torque at any other position of the rod. The device, which is clamped to a fishing rod forward of the fishing reel, comprises a flat cylindrical casing 1 with a cover and a strike rod 5 pivoted at the centre of the casing and extending through a slot 10 in the casing, the outer end of the strike rod being cranked so as to engage the fishing line when rotated. The pivot pin 6 fits loosely in the pivot hole of the strike rod to allow slight movement of the rod at right angles to its plane of rotation and the ends of the pivot pin are journalled in bosses at the centres of the casing and cover. Two sets of three side by side springs 12 extend from lugs 13 fixed to the casing to engage slidably two rails 14 secured to the strike rod in spaced parallel relation therewith and as the strike rod is rotated manually in an anticlockwise direction the springs extend and their ends slide radially inwardly along the rails until arrested by adjustable stops 15 positioned on the rails so that the torque exerted in a clockwise direction by the springs when arrested is almost zero. The strike rod is set by positioning a bearing piece 16 on the rod on a seating 17 in a transverse slot 18 at the upper end of the slot 10 and the effective size of the seating 17 is adjusted by a lever 19 which is pivoted to the casing at 20 so that it traverses the slot 18; the lever 19 is curved to engage the casing frictionally and its free end indicates on markings on the casing the size of the seating and hence the sensitivity of the setting. The release mechanism consists of a flexible resilient member such as a spiral spring 23 secured at one end to a sleeve 24 adjustably secured by a set screw 28 to the boss at the centre of the casing; the other end 26 of the spring passes through an arcuate slot 25 in the bottom of the casing to contact the part of the line between the reel and a pulley 27 on the fishing rod. The part of the spring 23 just inside the casing is enlarged so that when the line is moved by a fish taking the bait this enlarged part pushes the rod off its seating, whereupon the springs 12 rotate the rod with increasing torque and the cranked end of the rod strikes the line. The strike rod is arrested by its end inside the casing striking a leaf spring 29 fixed to the casing and positioned so that the rod is stopped before the bearing piece 16 strikes the lower end of the slot 10.

Title: Improvements in or relating to colour reproduction systems
Inventor: MAWBY DAVID HARRY
IPC: G03F3/08
Filed: 1958-07-18
Abstract: 857,654. Copying by scanning. CROSFIELD Ltd., J. F. July 17, 1959 [July 18, 1958], No. 23162/58. Class 40(3). Relates to a colour reproduction system utilizing a black printer and employing colour correction and undercolour removal. In such a system, Fig. 1, a colour separation printer image is produced by the direct exposure of a photographic plate 18 to a colour separation transparency 10 which is illuminated by scanning light from a source 6, the light also serving to illuminate further transparencies 10 so as to produce signals in photo-electric cells 12 which are applied via a computer 14 to modulate the intensity of the light source so as to reduce the density of a positive image resulting from the exposure in accordance with desired colour correction and undercolour removal. As illustrated, three transparency positions are provided, the photographic plate always being placed in contact with the centre negative. The left-hand negative serves primarily for colour correction whilst the right-hand negative serves for undercolour removal. Figs. 2, 3 and 4 show how the system is set up to produce respectively magenta, yellow and cyan images from red (R), green (G) and blue (B) colour separation negatives and an undercolour removal negative U (see below). The cyan printer, Fig. 4, does not require large colour correction from one of the other colours and is employed to correct itself by bringing into use a photo-electric cell responsive to light traversing the centre transparency and associated photographic plate. For this purpose the photographic plate is backed by a filter 22 which rejects light of a colour to which the plate is sensitive but passes all other colours. This photo-electric cell may also be used in producing yellow and magenta images. The undercolour removal negative U is produced by direct exposure of a photographic plate to white light transmitted through or reflected from the original or by exposure to a number of colour components of the original, the light source having, if desired, a colour bias. Fig. 5 shows how the system is set up for production of a "black printer" image, the photographic plate being placed in contact with the undercolour removal negative, whilst the red and blue negative are employed to produce signals to reduce the image density in coloured areas. According to an alternative method of working, the red negative is used for undercolour removal during production of the magenta and yellow images by increasing its effect to an extent greater than that required for colour correction. Reference is also made to the use of four transparency positions, two being employed for colour correction instead in one as in Fig. 1. The scanning may be effected by the use of a cathode-ray tube light source, as shown in Fig. 1, or a rotating drum or oscillating table. Specification 857,234 is referred to in connection with a method of correcting the characteristic curve of the photographic plate. Specification 835,111 also is referred to.

Title: Production of sulphur dioxide
IPC: C01B17/50
Filed: 1957-07-22
Abstract: In a continuous process for the production of a sulphur dioxide containing gaseous mixture by decomposition of calcium sulphate by contact with a burning fuel in a furnace, the calcium sulphate is preheated before decomposition by contact with the gaseous mixture withdrawn from the furnace.  Preheating of the calcium sulphate to 300-750 DEG  C. preferably 530-600 DEG  C. may be carried out in a heat exchanger, e.g. a set of cascaded cyclones (as defined).  The furnace is preferably a rotating furnace, the gaseous mixture being withdrawn from the same end as the calcium sulphate enters.  Fuel may be oil or combustible gas, but preferably pulverized coal introduced into the furnace through a burner at the opposite end to that at which the calcium sulphate enters.  Calcium sulphate which may be in the form of anhydrite flour may contain or be admixed with silica, e.g. sand, before decomposition to yield a calcium oxide containing hydraulic cement as a by-product.  The gaseous mixture after leaving the heat exchanger is filtered to remove entrained solids, e.g. by passage through an electrostatic precipitator, and may be passed to a sulphuric acid plant.

Filed: 1939-08-11
Abstract: 533,367. Centrifugal separators. BRISTOL AEROPLANE CO., Ltd., BUTLER, L. F. G., and UNDERWOOD, H. T. Aug. 11. 1939, No. 23237. [Class 23] [Also in Group XXIV] In a hydraulically operated clutch, e.g. such as is described in Specification 465,612, [Group XXIV], in which the hydraulic liquid is subjected. to rotation within the clutch mechanism, the hydraulic liquid before passing into the clutch, is passed through a centrifugal separator separate from the clutch but driven therewith, so that deposit of sludge from the liquid on to the clutch mechanism is prevented. Figs. 2 and 4 show a suitable form of separator for use with a clutch driving a supercharging blower of an internal combustion engine. The-separator comprises two cylinders 76. 77 fixed by nuts 72, 73 to a shaft 68 having an integral diaphragm 69 formed with teeth 32 by which the separator is driven from the clutch. The shaft 68 is mounted to rotate upon a fixed spindle 39 by means of bushes 70, 71 fixed to the shaft. The spindle 39 is provided with axial bores 44, 45 one of which 44 communicates by passages 47, 50, 49, 52 with the liquid supply, e.g. the oil from the lubricating system of the engine and the other, 45 by passages 62, 64 with a valve controlling the supply of oil to the clutch. The cylinders 76, 77 are each divided into light compartments by radial partitions and these partitions and the diaphragm 69 are provided with openings so arranged that the oil entering the bore 44 and passing into the cylinder 77 is directed through a zig-zag path before leaving the cylinder 76 and entering the bore 45. Sludge in the oil collects on the inside walls of the cylinders 76, 77.

Title: Improvements in or relating to methods and apparatus for controlling the successive positions of a movable part
Inventor: FOUASSIN MARCEL
IPC: G06G7/64
Filed: 1961-06-27
Abstract: 953,561. Rolling. ATELIERS DE CONSTRUCTIONS ELECTRIQUES DE CHARLEROI. June 27, 1961 [June 28, 1960], No. 23269/61. Heading B3M. [Also in Division G4] In a system for controlling a reversible rolling mill, the initial and desired final dimensions of an ingot to be processed are registered in respective first and second digital stores, and an analogue computer supplied with the analogue equivalents of these dimensions programmes the system and controls the rolls during the passes of the ingot through the rolls between the first and final passes. In Fig. 3 the first digital store comprises two sections 111-113 and 116- 118 into both of which the initial size of the ingot is entered. One of these sections is selected by relay 110 and the stored information is supplied to a digital control device 17 which may be a system as described in Specification 758,765. In addition, the analogue equivalent of the initial size is supplied over lead 119 or 114 to movable contact 81. The desired final size of the ingot is registered in store 121-123 and the analogue equivalent is supplied to wiper 83. The chain of resistors 80 (which may have different values) constitutes the analogue computer and produces at each tapping point between wipers 81, 83 a voltage which represents the size of the gap between the rolls for successive passes. Wiper 82 is ganged to wiper 81 and the two wipers are advanced together each time the mill reverses at the end of a pass, relay 110 being switched over to its other position at the same time. In this way, while one store section 111-113 or 116-118 is controlling the pressure screws of the rolls through device 17 during a pass, the other store section has its registration changed to the size of the gap for the next following pass, this being done by means of comparator 100 which compares the analogue voltage from wiper 82 with that from the appropriate store section and drives a follow-up system to alter the registration in that store section until the two voltages are equal. The system initially automatically adjusts the programme i.e. the number of passes to be made so that the reduction in size during the first pass does not exceed a permissible maximum entered in a store 115. The potential difference between wipers 81, 82 is applied to one input of comparator 107, the other input of which is from store 115. Comparator 107 drives wiper 83 until the desired voltage across wipers 81, 82 is obtained. The number of passes to be made may also be adjusted automatically or manually during the rolling process if the ingot cools down too much for the programmed reduction in size to take place during a pass. If, after a certain ingot dimension has been achieved, the ingot is rolled on edge between grooves, an additional voltage corresponding to the depth of the grooves may be added from source 106.
