Title: Improvements in or relating to trimming materials in ships' holds and other confined spaces
IPC: B63B27/22
Filed: 1921-04-28
Abstract: 170,702. Foord, A. N., Rowe, S., and Townsley, A. April 28, 1921. Trimming and spreading apparatus.-Trimming-propellers are arranged at the sides or ends of the hatchway of a vessel, or the opening of a storage chamber, so that they can be brought into operation after the hatchway has been run up full of cargo. Thus two propellers may be arranged centrally, one at each end or side of the hatch, or any number up to four may be arranged at the corners. Preferably the propellers are arranged so that their blades lie clear of the hatchway when not in use, as shown in Fig. 2, in which case they can form part of the permanent equipment of the vessel without interfering with the handling of other kinds of cargo not requiring to be trimmed. Suitable driving-gear, for example bevel-gear g or a belt pulley j, may be employed, and the propellers may have any convenient number of fixed or adjustable blades which may be set to various angles to deal with different materials, or the propellers may be interchangeable for this purpose. A lengthening-shaft d<1> may be connected detachably to the main propeller shaft to drive an additional propeller to operate below lower decks when necessary. Deflecting-plates k may be fitted underneath the deck. In operation, the hatchway is run up full of cargo as shown in dotted lines from the centrally-arranged discharge spout m. The spout is then moved near to one of the propellers, which is set in motion to distribute the continued discharge. When the corresponding part of the hold is filled, the spout is moved near to another propeller and so on until the whole of the space in the hold is dealt with.

Title: Improvements in or relating to chock-releases, collapsible pit-props and like devices
IPC: E21D15/60
Filed: 1950-09-28
Abstract: 684,643. Chock - releases; pit props. REID, W. July 6, 1951 [Sept. 28, 1950]. No. 23724/50. Class 20 (ii). A chock-release or collapsable head for a pit prop comprises two wedges 1, 2, Fig. 3, with engaging inclined surfaces locked to each other by means of a sprag 15 pivoted on a horizontal pin 12 to the wedge 1 and engaging an arcuate abutment surface 9 on the wedge 2, the surface 9 being struck about an axis 16 so displaced from the pivot axis 11 of the sprag 15 that rotation of the sprag towards release position, when the sprag 15 is clear of the surface 9, is accompanied by slow movement of the wedge 1 down the wedge 2 to afford an initial load relief and facilitating final release. Initial rotation of the sprag 15 causes its lower end to move up the surface 9 and shortens the distance between the pivot axis 11 and the position of contact with the surface 9, thus allowing the wedge 1 to drop to a small extent. A lever arm 17 is provided for rotation of the sprag 15. The inclined surface 5, Fig. 5, of the wedge 1 is interrupted centrally along its length to allow passage of the projecting abutment surface 9 and engages a central guide rib 10, Fig. 3, on the upper part of the inclined surface of the wedge 2, the lower part being interrupted to provide the abutment 9 and allow passage of the sprag 15. The sprag 15 is pivoted on the pin 12 by means of spaced ends 14, Fig. 5, which provide clearance for the abutment 9. Holes 23, Fig. 3, permit strops (not shown) to connect chock releases together.

Title: Improvements in and relating to the manufacture of light sensitive gelatine-silver halide photographic layers
Inventor: STEVENS GUY WILLIAM WILLIS
IPC: G03C1/74
Filed: 1950-09-29
Abstract: 688,980. Photographic gelatino-silver halide elements. KODAK, Ltd. Dec. 27, 1951 [Sept. 29, 1950], No. 23921/50. Class 98 (ii). A fluent gelatino-silver halide emulsion is coated on a support as of glass and sedimentation of the silver halide is effected by gravity or centrifugal force, while maintaining fluidity, until at least 70 per cent of it has settled to a layer adjacent the support and the emulsion coating is allowed to dry without removal of the supernatant gelatine. The emulsion may be of customary concentration and maintained, after coating, in a humid atmosphere at the temperature at which it is fluent and finally allowed to set and dry, or may be a diluted emulsion and kept at room temperature for the settling with a final setting operation by evaporation of water. The coating operation may be facilitated by reducing the temperature at coating, with subsequent raising of the temperature; or by first wetting the surface of the support with emulsion and subsequently pouring on the remainder to produce a uniform coating. The elements, after drying, have silver halide grains crowded together near the support and an upper portion consisting mostly of gelatine; and are normally stored and used, as for spectroscopy, photo-mechanical half-tone or line work, microphotography and press photography in this form; but the upper, gelatine, portion may be removed by simply washing the plates in water at elevated temperature and the result of this washing is a Schumann type plate with a layer rich in silver halide and extremely adherent to the support, and, due to the low gelatine content, sensitive down to 1900 A or further in the ultra-violet. Examples are directed to the use of an emulsion of motion-picture positive type and an undyed coarse-grain high-speed negative emulsion, which are diluted with water and then treated as above. Development is rapid and a highly restrained developer is recommended.

Title: Improvements in and relating to television cameras
Inventor: SPOONER ARCHER MICHAEL
IPC: H04N5/272
Filed: 1950-09-29
Abstract: 748,821. Television. BRITISH BROADCASTING CORPORATION. Oct. 1, 1951 [Sept. 29, 1950], No. 23950/50. Class 40 (3). In television apparatus for generating a composite signal as described in Specification 743,402 whereby at a receiver there is produced a picture in which part of an image viewed by a first camera is replaced by an image viewed by a second camera, the necessary switching of the two cameras being effected by control pulses generated by a photo-electric cell viewing. an unmodulated raster through a mask having a profile corresponding to said part of the image viewed by the first camera, means are provided for coupling the two cameras and the assembly of mask and raster whereby movement of one camera is automatically followed by a corresponding movement of the other and a corresponding change in the relative sizes and/or relative positions of the mask and raster. When the first camera executes a tracking movement, the corresponding movement of the second camera is similar, and the size of mask relatively to that of the raster as seen by the photoelectric cell is increased and reduced respectively as the camera moves backwards and forwards. This latter change is effected either by movement of the mask or by change in the size of the raster. When movement of the first camera is a tilting or panning movement, the second camera makes a similar movement and a change is made in the vertical and horizontal direction of the relative, position of mask and raster, either mechanically, by movement of the mask, or electrically, by movement of the raster. The necessary movements and changes in the relative sizes and/or positions depend upon the angles of the two camera lenses and the scale of the two images viewed by the cameras. Fig. 1 illustrates a servo system for controlling the two camera tracking movements. The first camera 17 unbalances the bridge circuit by variation of resistor 10 and an amplifier 16 responsive to the unbalance voltage controls a motor 18 to effect a corresponding movement of the second camera 19 until balance is re-established by resistor 11. The degree of movement of the second camera may be varied by adjusting resistors 12 and 13. Similar servo systems control the tilting and panning movements, and may also control the position of the mask. Alternatively the raster may be shifted by the arrangement shown in Fig. 2 in which a variable direct current is passed into the deflection coils by triode 23 under control of potentiometer 24 mechanically coupled to the first camera. Changes in the size of the raster in response to the tracking movement of the first camera may be effected by controlling the gain of the scanning amplifiers by a voltage developed by a potentiometer coupled to the wheels of the camera dolly. Specification 672,895, [Group XXXVIII], is referred to in the Provisional Specification.

The rotary member i, Fig. 1, is formed of built-up sections, or as a single unit, and is mounted in a frame formed with a platform c for the driving-motor d, with a receptacle b for the printed sheets, and with brackets e for the operator's platform f. The member i is divided into three sectors A<1> A<2>, A<3>, which may all be covered with rubber, the sector A<1> being arranged to pick up moisture from a roller m<1> on a lever n operated by a cam o on the member i, and the sector A<2> picks up ink from a similarly mounted rollers r on an oscillating lever s. The roller r receives ink from a distributing-roller q supplied by a messenger roller 2 and fitted with axially reciprocating distributors 5, all the inking- rollers being driven from a countershaft u<2> driven hy worm gearing from the motor d. For direct printing, sheets are fed by the aid of a front stop 21 and dropping rollers 20 to the sector A<3>, and a lithographic printing roller p is mounted in the position shown and adjusted by a nut 10. This roller is first damped by the sector A<1>, inked bv the sector A<2>, and then prints on the sheet carried by the sector A<3>. For offset printing an impression roller 14 is used and this is also adjustable by a nut, the printing being effected between the sector A<3> and impression roller 14. For printing both sides of a sheet simultaneously, the roller 14 is replaced by a printing-roller, and the roller p is used to print an offset impression on to the sector A<3>. The rollers 14, p are fitted with means to trip them when they are not required to operate. The roller p is driven by friction from the shaft of the member i, but is fitted with gear teeth 12, Fig. 10, to co-operate with gear blocks 13 on the member i to ensure correct register. The sector A<2> may receive ink from rollers which are supplied bv a messenger roller direct from a duct roller, and the ink is in this case distributed on the sector A<2> by rollers 5 which are moved to and from the sector A<2> by a cam.

Abstract: 539,579. Food preparations; treating soya beans; confectionery. FERREE, J. C. Aug. 23, 1939, No. 24289. [Classes 28 (i) and 49] [Also in Group I] A liquid which can be whipped to form a foam resembling whipped egg white is produced by extracting with water soya bean flour, from which the fat has been removed by a solvent, and removing solid matter from the water extract. The extract may be evaporated to dryness to produce a powder which will foam when whipped with water. The whipping power of the extract can be increased (a) by adjusting its pH value to about 5, as by adding HCl, when a precipitate, presumed to be glycinin, is formed, and removing this precipitate ; the extract is preferably neutralised before using in cooking or evaporating to dryness ; or (b) by acidifying to pH5 the water used in extraction. The extracted flour may be subjected to a second extraction. Objectionable soya bean flavour can be removed from the fat-free flour before extraction by heating a flat layer several millimetres thick in an electric oven under 45 mm. of mercury at 120‹ C. for 20 minutes. The products of the invention can be used as egg white substitute in making meringues, marshmallows &c. or may be whipped in fruit juice or sugar syrup to make cold whips, toppings and frozen desserts.
