Filed: 1945-03-27
Abstract: 620,302. Printing. LETOUZEY, V. J. E. March 27, 1945, No. 7720. Convention date, Dec. 14, 1942. [Class 100 (ii)] The height of each of a set of types is determined as a function of the ratio between the printing part of the type and the total area of the type face and increases as the ratio increases, with the object of providing uniform pressure of the types on the paper and avoiding the necessity for make-ready. The height may vary from 0.12 of a millimetre less than standard type height for a type printing only a few slight lines to 0.06 greater when the whole of the face prints. Fig. 5 shows types 3<SP>1</SP> ... 3<SP>7</SP> of various heights composed on a stone 2, the types 31, 3<SP>4</SP> being of normal height, the types 3<SP>3</SP>, 3' 0.03 higher and the types 3<SP>2</SP> and 3<SP>6</SP> 0.04 and 0.06 lower respectively. An impression cylinder 4 carries a rubber blanket 5 of thickness 0.154 millimetres under pressure and 0.164 without pressure. The Specification as open to inspection under Sect. 91 describes also (1) moulds of various depths for casting the types: the moulds may be made by driving punches into blanks to various depths; and (2) rules of different heights according to whether they are perpendicular to or parallel to the axis of an impression cylinder. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to apparatus for monitoring radio transmissions
IPC: H03J7/32
Filed: 1941-06-20
Abstract: 577,240. Wireless receiving apparatus. CLARK, H. A. M. June 20, 1941, No. 7787. [Class 40 (v)] [Also in Group XXXVI] Apparatus for monitoring radio transmission comprises a radio receiver adapted to be tuned repeatedly through a frequency band to be monitored, a cathode ray tube having a long lag screen, means for deflecting the electron beam of the tube in one direction in accordance with the tuning of the receiver, means for controlling the intensity of the beam in accordance with the output of the receiver, and means for progressively deflecting said beam in another direction, the arrangement being such that in operation the traces which appear on the screen when transmissions are received indicate at any instant the frequencies of the transmissions by their own positions in the first-mentioned direction and the time of transmission by their position and extent in the other direction. A sawtooth oscillator serves to vary the frequency response of a master receiver over a wide band and also to effect scanning of the electron beam of a cathode ray tube to the grid of which is applied the rectified output of the receiver through a limiter to give a trace of uniform size and the position of which corresponds to the frequency of the received transmission. A second oscillator of lower frequency causes the scanning axis to move in a transverse direction so that each transmission is shown by a vertical trace. It is thus possible to identify stations in communication with each other by observing the termination of a trace followed by the appearance of a new trace at a different position on the frequency scale. A monitoring receiver is provided for each of the observed transmitter and the vertical scanning may be switched in only towards the expected end of one transmission in order to detect the other communicating transmitter. The monitoring receiver may be provided with a weak oscillator which i causes a trace on the tube corresponding with the tuning of the receiver, which trace can be made to coincide with the observed trace so as to facilitate rapid tuning. The cathode ray tube may be enclosed in a darkened chamber provided with a photo-electric cell feeding a differentiating circuit which provides an output pulse on the occurrence or disappearance of a trace. These pulses may be used for indicating the frequencies of the transmissions or may be used for effecting tuning of the monitoring receivers.

Abstract: 1,040,428. Buckles. G. Q. PARACHUTE CO. Ltd. Jan. 14, 1965 [Feb. 27, 1964], No. 8154/64. Headings E2A and E2B. A buckle comprises a slidable bar 16 engageable with a strap end portion, a member against which the strap end portion is held by the bar 16, means which exert pressure on the strap end portion against the bar, which pressure can be relaxed to allow the strap end portion to be adjusted, and means by which the said member can be moved away from the bar to release the strap end portion. As described the buckle comprises two bars 16 having end portions 18 slidable in slots 14, and the corresponding members are bars 17 carried by connecting plates 22 and slidable in slots 15. In use the strap end portions are passed round the bars 16 and are held by pressure plates 38 urged outwardly by pins 37 which engage cam surfaces 34 of an operating plunger connected to a knob (not shown). Tension on the strap end portions moves the bars 16 towards the bars 17 to further grip the portions. To release the strap end portions the knob is rotated to relax the pressure exerted by the plates 38, and then the knob is depressed so that rods connected thereto act via pins 26, 23 and crank 24 to move the connecting plates 22 and hence move the bars 17 away from the bars 16 to release pressure on the strap end portions and allow them to be freed.

Abstract: 1,145,022. Calcium fluorosilicate; phosphoric acid; alkali metal fluorosilicate; HF; SiF 4 . FARBWERKE HOECHST A.G. 25 Feb., 1966 [27 Feb., 1965], No. 8434/66. Heading C1A. The fluorine values in crude phosphate rock are obtained as calcium fluorosilicate by digesting the crude phosphate with aqueous nitric or hydrochloric acid and in a concentration such that the resulting digestion solution contains, when nitric acid is used, 20-40% of water or when hydrochloric acid is used, 40-60% of water, said water percentages being calculated on the total weight of aqueous acid and crude phosphate and separating hydrated calcium fluoro-silicate (CaSiF 6 .2H 2 O) from the undissolved matter obtained from the digestion solution. Preferred ranges of water content calculated on the above basis are 28-32% for HNO 3  and 45 to 50% for HCl. The nitrated digestion solution is preferably cooled to a temperature in the range 0‹ to 10‹ C. and the undissolved CaSiF 6  and CaF 2  separated from the larger crystals of Ca(NO 3 ) 2 .4H 2 O. The separation may be achieved using a sedimentation or a solid jacket centrifuge. The insoluble fluorosilicate obtained may be treated with dil. acid, filtered and alkali metal fluorosilicate obtained by the addition of an alkali metal salt to the filtrate. The residue from the filtration may be distilled with H 2 SO 4  to give HF and SiF 4 .

Abstract: 826,725. Electric digital-data-storage apparatus. SOLARTRON ELECTRONIC GROUP Ltd. March 19, 1956 [March 23, 1955], No. 8507/55. Class 106 (1). [Also in Group XL (b)] An information storage apparatus includes a storage screen such that an optical characteristic of its elemental regions is varied by a light beam, a lenticular plate of lenses, means to scan the screen through the plate with a light beam modulated with information to be stored in a raster of rows of spots with interstices larger than the spot size, and means to vary the angle of the light incident on the plate, scanning taking place in many rasters interlaced in line and frame directions. The apparatus as described has a lenticular plate 17 backed by dichromophore 18 whose light transmission properties vary with electric field, insulator 19 which transmits red and reflects blue light and a selenium layer 20 charged by brush discharge from a high potential pulse applied to electrode 21. Red light-emitting cathode-ray tube 22 is modulated at grid B by the information to be stored, tube 10 being biased off by bias 28; or tube 22 may remain unmodulated and the information be contained in a mask over its screen. Screen image 23 is transferred to lenticular plate, successive rasters appearing in interlaced relation by Nipkow disc 15 rotation. The information is stored on the dichromophore as oriented crystals where there has been no illumination and as randomly arranged crystals where light has fallen. Reading of the stored information is by means of unmodulated " blue " tube 10 and photo-cell 24, tube 22 being inoperative. Polarized blue light from screen 11 is absorbed on areas of oriented crystals on the dichromophore but passes through other areas and thence to photo-cell 24 via layer 19, plate 17, half-silvered mirror 14 and blue filter 25. Clock pulses from generator 27 determine the number of information-bearing spots in each scanning line. For storage times longer than that possible with the dichromophore two such systems may be used, the second system storing whilst the first is being read, Figs. 2-4 (not shown). Specifications 513,776 and 514,155, [both in Group XL], are referred to.

Filed: 1947-03-28
Abstract: 640,711. Automatic temperature control systems. MINNEAPOLIS - HONEYWELL REGULATOR CO. March 28, 1947, No. 8533. Convention date, March 29, 1946. [Class 38 (iv)] In a pyrometer for measuring relatively low temperatures the temperature of the housing is maintained constant at a temperature higher than that of surrounding objects or alternatively the housing is maintained at the same temperature as that of the body being measured, so as to minimize errors due to ambient temperature variations. The pyrometer comprises a body structure A, Fig. 1, in which are mounted a thermopile B and a lens C. The thermopile B is supported in a metallic housing D, the hot junction being located in a small chamber D<SP>2</SP>, whilst the lens may be mounted in the housing D or in the pyrometer housing (Fig. 3, not shown). The thermopile connections are taken from binding posts D<SP>3</SP>. A thermostat F and a heating element E surrounding the structure A are also provided. The thermostat F. is in the form of a mercury thermometer and is such that at a predetermined temperature the mercury will close contacts F<SP>1</SP> and F<SP>2</SP> connected externally to a binding post H<SP>1</SP>. The thermopile connections are brought to a binding post H<SP>2</SP> whilst the heater connections are brought to a binding post H<SP>3</SP>. The heater is energized by supply lines 1, 2 through a relay contact G<SP>2</SP> enclosed in a controller G, the operating coil 5 of the relay being connected in the thermostat F circuit and energized when contacts Fl and F<SP>2</SP> are made. The thermopile contacts H<SP>2</SP> are connected to an indicator unit I also energized from supply lines 1, 2. The temperature of the housing is then maintained at a constant level since if this temperature is exceeded the controller G will operate to disconnect the supply to the heater. In a modification, a thermocouple type of thermostat with a suitable controller may be used instead of the mercury thermometer type of thermostat F. In a further embodiment the temperature of the housing is maintained at the same level as that of the body X which is being measured, Fig. 5. The thermocouple L in this case provides a measure of the temperature of the body X and is connected to an indicator I. The thermopile B and heater E are connected to a controller GA, responsive to the difference between the hot and cold junction temperatures of the thermopile, and arranged to energize the heater so that the cold junction is maintained at the same temperature as the hot junction. In modifications a compensating voltage is introduced to compensate for hot and cold junction difference temperatures when the temperature of the body X varies rapidly (Figs. 6 and 7, not shown). In a further modification the radiation responsive element may be one arm of the resistance bridge of a bolometer (Fig. 8, not shown). U.S.A. Specification 2,357,193 is referred to.

Abstract: 955,726. Casting processes. H. J. DAUSSAN. March 9, 1961 [March 17, 1960], No. 8614/61. Heading B3F. [Also in Division B5] A shock-absorber for use in the casting of metals in an ingot mould is made from a pliant and inextensible composite web which is compressible in thickness and comprises at least one plane web 1 (Fig. 1), of cardboard, faced corrugated cardboard, pliant synthetic plastics material or other pliant material, a wavy or corrugated web 2 of the same or other pliant material, the crests of the waves of this web adjoining and being fixed to the plane web, and at least one narrow longitudinal reinforcement 3, which is elastically bendable, is e.g. of steel wire or strip, is held between the two webs and is corrugated to substantially the same shape as the wavy or corrugated web. The layers may be clipped together by clips that secure the reinforcements 3 to the other layers, or are so applied that the reinforcements run between lines or clips, which therefore secure the plies 1 and 2 only to one another. In other embodiments, there are two parallel reinforcements; or a facing ply is stuck, e.g. by adhesive, such as sodium silicate, to the crests a, c, e of the corrugated ply. As shown in Fig. 15, the composite web is wound in a spiral round a mandrel, then pressed between two parallel plates and held in its compressed shape by the laths 25 and 26 and connecting members 27 and 28. The assembly is then dipped in an adhesive, glue or sodium silicate, and the laths can then be removed. They must however be replaced and the assembly further compressed before it is inserted as shown, through the neck of a bottle-type ingot mould L. The members 27 and 28 are cut and the assembly falls or is pushed to the position A at the bottom of the mould. The Specification also refers to the use of the material as rings or frame floats, ring floats and dead-head equipment.
