Title: Improvements in photosensitive silver halide emulsions for use in half-tone photographic processes
IPC: G03F5/00
Filed: 1952-06-27
Abstract: 701,891. Hatf-tone photography. KODAK, Ltd. June 27, 1952 [June 29, 1951], No. 16184/52. Class 98(2) A pre-screened silver halide material which forms a half-tone record directly when exposed to a continuous tone image is made by pressing a hard surface provided with a half-tone pattern of raised dots against a silver halide emulsion layer as of process type, or, preferably, of lith type with a maximum gamma greater than 4. The pressure causes desensitization, and the raised dots of the hard surface may have rounded tops, producing, in the emulsion layer, areas of minimum sensitivity varying continuously to areas of maximum sensitivity, since the desensitizing effect of pressure extends somewhat to areas adjacent to those pressed; or these raised dots may have flat tops producing extended areas of minimum sensitivity. Normally the pressure is effected in presence of moisture, and various ways of applying the moisture are described. An additional effect is obtained when the tops of the raised dots carry a chemical desensitizing agent such as methylene blue, pinakryptol yellow, or phenosafranin. Fig. 2 shows production of the prescreened material by passing a film 16 carrying silver halide emulsion layer 17 between hardsurface roller 18 with raised dots 21 in half-tone pattern and back pressure roller 19; water 23 is applied by roller 22 with optional use of wiper 26; driers 27 remove moisture from the film. Other figures illustrate a variety of shapes of raised dots which may be provided on the hard surface or roller and the desensitizing effect produced thereby on the emulsion layer. Specification 474,911 is referred to.

Title: Non-rotating antenna array producing a rotating limacon
IPC: H01Q25/04
Filed: 1974-04-11
Abstract: 1460796 Aerials INTERNATIONAL STANDARD ELECTRIC CORP 11 April 1974 [18 April 1973] 16219/74 Heading H4A A method of modulating a transmitter carrier signal in the distribution cavity 3 of a non- rotating aerial array, which array produces a rotating limacon radiation pattern, includes the steps of injecting said carrier signal into the centre conductor 5 of an RF impedance transformer located within said distribution cavity, and sequentially exciting, according to a predetermined pattern, a plurality of probes 4 to set up the H 11  coaxial mode of propagation in the cavity. The method further includes adjusting the phases of the RF currents in the excited probes, by loading means associated therewith, to bring the resulting modulation component in phase with the carrier at a desired operating frequency, extracting output signals having the desired amplitude and phase relationships from the transformer, and applying them to respective radiating elements of the aerial array. As described with reference to a TACAN beacon, the probes 4 project radially inwards from the outer wall of the cavity to which they are connected via diodes 10. Bias voltage is applied to the diodes through chokes 11 so that each probe may either be isolated from the cavity wall (associated diode non- conductive) or be connected thereto (associated diode conductive). In the latter event, the relevant probe is excited by the normal TEM mode of the carrier input signal. A 15 Hz modulation is produced by sequentially biasing the diodes according to a predetermined pattern and sequence to excite the H 11  coaxial mode of propagation, and extracting output signals on leads 6 at the low impedance end of the transformer for coupling to respective radiators of a circular aerial array (Fig. 2, not shown). The leads 6 include diodes which are sequentially switched to provide a 135 Hz modulation. Diode switching is effected by control logic 12, Fig. 4, with an associated clock 13. For the 15 Hz modulation it has been found that simultaneous excitation of three probes in a 32-probe arrangement reduces the formation of the unwanted H 21  mode within the cavity. Thus, the probes AEI are excited together at one step, the angular separation between adjacent pairs of probes being 45 degrees. The steps in the sequence which follow might be AEJ, AFJ, BFJ, BFK, and so on. The loading of the probes 4 may be either reactive or resistive or reactive and resistive (Figs. 7 to 13, not shown).

Title: An improved method of reducing potatoes and other starch-containing vegetables to the form of a dry powder
IPC: A23L19/15
Filed: 1936-06-10
Abstract: Potatoes and other starch-containing vegetables are reduced to dry powdered condition in which the starch is preserved in its initial form by cooking at a temperature which is not substantially over 100 DEG  C., cutting into small pieces, partially drying at a temperature not substantially over 100 DEG  C. until at most 60 per cent by weight of the initial water content has been removed, reducing to a moist powder and finally drying at a temperature not much over 80 DEG C. to a moisture content of 10-15 per cent.  Potatoes are peeled and placed in an open basket or a series of foraminous trays and inserted in a jacketted vessel which is then closed by a cover having an automatic pressure-release valve.  The potatoes are supported clear of the bottom in which is a small quantity of water.  Steam under pressure is supplied to the jacket and cooking is effected in about 15 mins. at about 100 DEG  C. but not over 105 DEG  C.  After cutting up the partial drying follows at about 100 DEG  C. but not over 105 DEG  C. followed by the final drying at not over 85 DEG  C. during which the mass is kept in motion by stirring &c.  Either or both the drying steps may be carried out in stages and under reduced pressure. The product may be used in admixture with water or milk and other ingredients in making mashed potatoes, soups &c.

IPC: A46B11/00
Filed: 1919-07-08
Abstract: 152,284. Grace, W. July 8, 1919. Piston apparatus for discharging receptacles.-In a reservoir brush wherein the material is fed to the brush-head by a plunger advanced by a screw, the plunger or the member coacting therewith is longitudinally slotted to give radial resiliency permitting a quick return of the plunger in refilling by the threads of the one slipping over the threads of the other. In the toothbrush shown in Fig. 2, the screwed head 37 and shank of the plunger 34 are. slotted at 46 to enable the plunger to be quickly pushed in from its forward position within the internally-screwed feed-barrel 39 when detached for the purpose from the handle 25. The feed-barrel 39 has an internal groove 42 in a turned-over flange 41 into which a beading 43 on the slotted end of the handle 25 springs. To prevent the plunger from rotating, the head 33 thereof is non-circular and engages a corresponding recess in the cork 32, which, with the cartridge, is also non-circular in section. In a modification, the plunger screws in the threaded end of the reservoir which is longitudinally slotted for the quick return, the plunger carrying an external sheath which thus telescopes over the reservoir and indicates by the position of its forward end the extent to which the contents of the cartridge have been extruded. In a further modification, described as a shoe-brush, the horizontal handle-grip constitutes the reservoir receiving the cartridge and slotted plunder as in Fig. 2, but the internally-screwed feed-barrel in this case is slotted at the inner end, on which end is formed a beading which springs into an internal groove in the handle. Specificaticn 153,627 is referred to.
