Title: Improvements in or relating to signalling means for marine and aerial navigation
IPC: B63B45/08
Filed: 1929-06-22
Abstract: 315,302. Pintsch Akt.-Ges., J. July 11, 1928, [Convention date]. Light, control of apparatus by. - A signalling device for marine and aerial navigation uses a light-sensitive cell whose circuit is completed only at certain intervals by clockwork. The cell a, Fig. 1, shielded by screen h from the lamp f so that it is acted upon by daylight only, is connected to the circuit controlling the valve e at intervals by a clockwork b, so that the valve e is adjusted at intervals only. The cell a, Fig. 2, is acted upon by the lamp only and is connected into the operating circuit at intervals by a clockwork b, the current causing the lamp 1 to be replaced by the lamp 2, on destruction or damage of lamp 1. The continuous use of batteries for the light sensitive cells is thus avoided. The clockwork may be rewound by gas pressure or electrically.

Title: Improvements relating to heat sensitive apparatus
IPC: G01F1/68
Filed: 1948-07-19
Abstract: 649,392. Electric indicating systems. SCOLES, G. J., and METROPOLITANVICKERS ELECTRICAL CO., Ltd. July 19, 1948, No. 19338. [Class 40 (i)] In heat-sensitive apparatus (Fig. 1) a bridge comprises a resistance A, a temperaturesensitive resistance C (e.g. a platinum wire), and a potentiometer B, D. The unbalance voltage across junctions BD and AC is fed back to the input of an amplifier, having maximum gain and minimum phase-shift at a given frequency, which feeds the input diagonal of the bridge through transformer T, in correct phase for stable constant frequency oscillation. Initially the potentiometer slider is adjusted so that the power dissipated in the bridge keeps the equilibrium temperature of C stable above the ambient temperature. Externally induced variation of the temperature of C changes its resistance to vary the bridge unbalance voltage, the amplifier output, and the power dissipated in C, until the latter is restored to its original temperature. The reading of a voltmeter across the amplifier output is a measure of the heat dissipated in C, and may be calibrated in terms of the external variable. In a yaw meter for detecting the direction of airflow in a wind tunnel, resistance C is a wire located close to an unheated wire, and when C lies in the wake of the latter, its heat losses are reduced, as shown by a fall in the voltmeter reading, and the direction of flow is determined. Fig. 2 shows a modification wherein bridge arm C is replaced by two identical temperature-sensitive resistances C1, C2 in series across a potentiometer E. A measuring instrument G is connected between the slide and the join of C1 and C2. The relation between their temperatures is indicated by the setting of the slider to give a zero reading of G. C1 and C2 may be used in a yaw meter as before.

Filed: 1945-07-28
Abstract: 596,526. Machinery safety devices. INGHAM, G. July 28, 1945, No. 19373. [Class 80(iv)] [Also in Group II] Current from the windings of the stator or rotor of the electric motor a of an electrically driven machine such as a centrifugal machine or hydro-extractor is utilised to actuate a locking bolt for the cover or guard or other part of the machine. As shown, the current from the stator windings passes through a rectifier c to close the contacts e of a moving coil relay d which places a negative voltage on the grid f<SP>1</SP> of a thermionic valve f, the resulting anode current being used to operate a further relay g to close contacts g<SP>1</SP> to operate a magnetic latch or bolt adapted to hold the cover of the machine in position. When the current to the motor is switched off the continued rotation of the rotor of the machine due to its own momentum induces a current in the stator winding which is effective to actuate the relay d until the motor actually stops.

IPC: B61G5/04
Filed: 1919-08-07
Abstract: 152,458. Spencer, A., and Craven, A. Aug. 7, 1919. Couplings, automatic.-In order to couple vehicles provided with couplings of the rotarydisk hook type with those having couplings of the Norwegian hook type, or during a transition period, the coupling-head of one vehicle carries a link e, Fig. 1, which is adapted to engage the rotary-disk hook g of the opposite vehicle or to be engaged, as shown in Fig. 5, by a hook h of the Norwegian type. In the construction shown in Figs. 1 and 5, the link comprises an inner part a pivoted to the coupling-head, and an outer part e pivoted at d to the inner part, the hook h engaging the pivot pin d when the outer part e is turned back. This form of coupling may be derived from two coupling-heads of the ordinary rotary-disc type by removing from one coupling- head both the rotary-disk and link and substituting a two-part link a, e, and by removing from the other coupling-head the link only, a filling- piece t being inserted in the elongated slot r for the replaced link so as to provide a fixed bearing for a two-part link a, e. In a modification shown in Fig. 6, a one-part link e is employed, the Norwegian hook being adapted to engage the pivot pin x, which in this case occupies the bearing formerly occupied by the pivot of the rotary-disk hook.

Title: Process for the preparation of granulated phosphate fertilizers
IPC: C05B19/02
Filed: 1963-05-16
Abstract: <PICT:1032613/C1/1> A granulated phosphate fertilizer having a base of superphosphate containing 20 to 40% by weight of P2O5, is prepared by mixing together (a) an ordinary superphosphate in substantially pulverulent form, formed by heating phosphate mineral with sulphuric acid containing 65 to 75% by weight of H2SO4, and (b) a fluid superphosphat mass formed by heating phosphate mineral with dilute phosphoric acid containing 25 to 33% by weight of P2O5, and then granulating and drying the mixture, followed by recycling part of the granulated and dried mixture by mixing it with (a) and (b).  The recycled part is preferably that part left after removing the granules of the desired size, e.g. by a screening operation.  The two coarse granules are preferably ground before being recycled. The fluid superphosphate mass preferably forms at least 15%, preferably 20%, by weight of the dry granulated phosphate fertilizer produced. Phosphoric acid may be mixed with the sulphuric acid in order to increase the P2O5 content of the fertilizer. A supplementary fertilizer, e.g. a potassium salt, may be added to the mixture prior to and during the granulation operation.  The process may be carried out continuously by controlling the rate of flow of the reactants to produce a mixture of products (a) and (b) in the desired proportions. In relation to the drawing, previously ground phosphate mineral is fed into mixer 4 from hopper 1 by conveyer 2.  Sulphuric acid, or a mixture of sulphuric and phosphoric acids, at a controlled rate, is also fed into mixer 4, by meter 3.  This mixture passes to rotary drum 5, containing scraper 6, and solidifies therein, and is converted into powder form and passes into granulating drum 7. Phosphate mineral and dilute phosphoric acid are introduced into vat 11 and the thus-produced fluid superphosphate mass overflows into drum 7, where it mixes with the powdered ordinary superphosphate from drum 5.  This mixture is then dried in rotary drier 13, and is screened at 16.  The granulated product of desired size is removed through 18, and the remaining granules are recycled to drum 7.  A supplementary fertilizer may be introduced into drum 7, from hopper 21 by conveyer 22.

Title: Improvements in or relating to printing machines
IPC: B41L39/08
Filed: 1920-07-08
Abstract: 147,682. American Multigraph Co., (Assignees of Trundle, G. T.). July 27, 1914, [Convention date]. Tripping and like arrangements.-A printing- machine, of the kind in which letters &c. are printed from type set in a drum which prints through an ink-ribbon and coacts with an impression roller and an automatic, or hand, sheetfeeding device, is constructed with eccentric bearings for the impression roller and spring means which tend to rotate the bearings to throw this roller out of printing position, this spring means being normally restrained by a latch which releases it if the sheet is not fed. As shown, a sheet P is fed by hand, or by automatic means, to spring-raised stops 65, which are depressed when a sectional feed-roll 55 is also depressed into contact with a roll 52 bv a cam 60 acting on a roller 59 on a lever 58, the cam 60 being carried by a printing-drum 10 co-operating with an im. pression roller 20. This roller is mounted on a spindle 21 fitted with eccentric journals as 23, Fig. 6, the one opposite to the journal 23 being mounted in an eccentric bush which can be adjusted to alter the inclination of the roller 20. The journal 23 is mounted in a bush 25 in the machine frame 15, and is connected to a spiral spring 70 which tends to rotate the spindle 21 in a direction to trip the roller 20. The journal 23 is fitted with an end-plate 40 shaped as shown in Fig. 2, and this plate is connected in an adjustable manner to a collar 41, which is formed with recesses 82, 97, Fig. 2, to receive latches 80, 96 respectively. The latch 96 is held in engagement with its notch 97 by the circumferential pressure of the straight edge of the notch on the latch, and by the action of the notch or pawl 80. Periodically, the latch 96 is released from both of these by the swinging of the pawl 80 to the right by means of a cam 88 acting on a roller 87 on a lever arm fixed to the shaft of the arm carrying the pawl 80. At this instant, if no sheet is being fed, the latch 96 is raised to permit rotation of the collar 41 and the eccentric bearings of the impression cylinder by a counterweighted lever 92 connected by an extension 94 and a screw 99 and spring 98 to the latch 96. The presence of a sheet, however, prevents the lever 92 from moving by acting on a finger 91 carried by the lever 92, and the latch 96 fails to release the impression tripping- device. The printing-machine, or the paper feed, may be simultaneously tripped by a screw 108 on the collar 41 acting on a projection 106 on a rod 105, which'is moved to throw out the drive of the machine or of the feeding-device. The cams 88 and 60 are preferably carried by a common ring adjustable relatively to the printing-drum. The impression cylinder is driven from the printing- drum by an Oldham coupling 31 and a gear-wheel 30, Fig. 6, mounted on an extension of the bushing 25 in which the journal 23 is mounted.

Title: Colorimeter
IPC: G01J3/46
Filed: 1948-07-22
Abstract: 670,780. Colorimeters. LEISER, R. July 22, 1948 [July 28, 1947], No. 19664/48. Class 97 (i). A colorimeter wherein the colour required to match the colour of a test-piece can be blended additively by colour filters disposed over a diaphragm aperture in the light path between a source and a lens system for forming a focused real image of the source, is characterized in that the colour filters are mounted in a rectangular frame on one side of a plane passing normally through two opposite side members of the frame whilst on the other side of the plane there is provided in said frame means for transmitting white light, and said frame is movable in a plane parallel to the plane of the diaphragm aperture and in either of two orthogonal directions, whereby the required matching colour can be produced. As shown in Fig. 2, the colorimeter comprises colour filters 2, 3 mounted in a frame 1 slidable in a guide 4 which is itself movable vertically. Each side of the frame 1 is twice as long as a side of a square diaphragm aperture abcd and one half of the frame 1 is empty or houses a transparent member which holds the filters 2, 3 in position and admits white light to the diaphragm aperture. By moving the frame 1 horizontally, the colour of the light admitted to the aperture abed changes gradually from that of one filter to that of the other filter and by moving the frame 4 vertically the intensity of the blended colour may be increased or reduced. A bar 5 depending from frame 4 has a projection 6 provided with a slot A and an opaque slide 7 has a slot 9 engaged with guiding pins m, n on a housing, and has a projection 8 formed with a slot B. The movements of the frame 4 and of the slide 7 are coupled by a lever C which is pivoted at 10 and has pins 12, 11 engaging the slots A and B, the pin 12 being adjustable along the lever C. In use, after vertical movement of the frame 4 to adjust the intensity of the blended colour, the pin 12 is secured to the lever C and this lever is actuated so that frame 4 and slide 7 are moved and the amount of white light in the blended colour is varied. The Specification as open to inspection under Sect. 91 describes also a colorimeter which comprises a housing 40, Fig. 4 (Cancelled), pivoted a- 43 to a stand 44 on a base 45 supporting a testt piece T. The test-piece is illuminated by light from a source 21, this light being directed thereon by a mirror 31 and reflected thereby through a lens 32 and a prism 26 into an eye-piece 27, 28. Light from the source 21 is also directed by a mirror 25 through the filters 2, 3 and diaphragm aperture abcd, Fig. 2, and through the lens 22 into the prism 26 whereby it is reflected into the eyepiece 27, 28 for comparison with the light from the test-piece T. This subject-matter does not appear in the Specification as accepted.
