Title: Process for the production of photographic images
Inventor: WEYDE EDITH
IPC: C07D239/56
Filed: 1966-05-19
Abstract: 1,125,646. Photographic physical development and materials. AGFA-GEVAERT A.G. May 19, 1966 [May 19, 1965; Aug.6, 1965], No.22288/66. Heading G2C. A supported layer containing an imagewise distribution of development nuclei for silver salts, is treated with an aqueous solution of a silver salt of phosphoric acid or of an aliphatic carboxylic acid, the aliphatic radical of which is substituted by a thioether group, at a pH of 1-7 in the presence of a developer which reduces the silver salt at the nuclei at that pH. Preferred carboxylates have the formula R-(S) n -X-COOAg wherein R is substituted or unsubstituted alkyl, aryl or heterocyclic group, n is 1 or 2, and X is a branched or unbranched alkylene chain. The imagewise nucleated layer may contain finely divided metals, e.g. Au or metal sulphides e.g. Ag 2 S or NiS, as nuclei, but is preferably an imagewise exposed silver halide emulsion layer. The soluble silver salt may be present in an aqueous processing solution or in a layer applied above or below the nucleated layer on the same or a separate support. The developer and an acid may be included in any layer or in the processing solution. When the silver salt is carried in a layer on a separate support a negative latent image, with respect to the nucleated layer (which may be positive with respect to the original), is formed in that layer. Alternatively, a silver salt layer may be overcoated with a light-sensitive silver halide layer in a soluble binder, imagewise exposing the layers to light, developing in an acid developer and dissolving off the top layer to leave a positive silver image. The silver salt layer may contain a low concentration, e.g. 1-150mg/m<SP>2</SP>, of uniformly distributed development nuclei.

Title: Improvements in or relating to automatic weft bobbin changing apparatus
IPC: D03D45/20
Filed: 1957-07-18
Abstract: 829,453. Automatic weft replenishing looms. FISCHER A.G., G. July 18, 1957 [July 25, 1956], No. 22805/57. Class 142(2) In a loom having two shuttles picked simultaneously one above the other and in the same direction through two sheds, bobbin changing is controlled by mechanism which feels the weft in the shuttle and subsequently when the slay is at front centre, moves forward beneath the inserter the compartment housing the exhausted shuttle. When the lower shuttle is to be replenished, the mechanism for moving both shuttle compartments is operated, but cam means prevents movement of the upper compartment. The changing mechanism 6 is lowered to present the magazine' to the lower box. If both bobbins require replenishing the shuttle in the lower compartment is replenished first. If the shuttle in the top box is to be replenished, the corresponding feeler energizes a solenoid 92 and a latch 96 is raised and releases a bell crank lever 82. A spring 88 then turns the lever 82 and a roller 81 thereon pivots a latch 71 into engagement with a catch 43 on a lever 38. The lever 38 is pivoted by a roller 39 and a cam 9 and swings a lever 36 on which the latch 71 is mounted. The magazine is made ready for weft changing by the actuation of a linkage 34, 31, 29, 27, 25 and the bobbin is changed. If the lower box is to be replenished a solenoid 102 is energized and a latch 74 depressed to engage the catch 43. Rotation of the cam 9 now causes movement of a lever 58 carrying a toothed segment 57 and on which the latch 74 is mounted and also of the lever 36 by means of a pin 60 in the lever 58. Movement of the levers 36, 58 away from abutments 70 on hook levers 64, 65 permits one of these levers 64, 65 to fall, depending upon the position of cam surfaces 55, 56 mounted on a pinion 53 meshing with the toothed seg-  ment 57. The lever which falls engages with its hooked end a pin 21 at the end of levers 15, 17 pivoted to the slay at 18, 19 and connected by members 10, 11 to the shuttle compartments 4, 5. When the slay moves forward, the lever 15 or 17 engaged by one of the levers 64, 65 is pivoted and moves the corresponding compartment 4 or 5 forward beneath the bobbin inserter.
Patent GB-405709-A (GB)
Title: Method of production of forms for planographic printing, particularly offset printing
IPC: B41N3/08
Filed: 1932-08-15
Abstract: 405,709. Printing-surfaces. BEKK & KAULEN CHEMISCHE FABRIK GES., DR., Loevenich, near Cologne, Germany. Aug. 15, 1932, No. 22819. Convention date, Dec. 9, 1931. [Class 100 (ii).] Planographic or offset printing-surfaces are prepared by applying the printing-image to a finely grained base and subsequently rendering the grain of the non-printing parts coarser by electrolytic treatment ; the grain can be similarly renewed when worn as a result of prolonged use. The image is applied to a base which is not attacked during the repeated production of the grained surface nor when etching to render the surface ink-rejecting. The plate is suspended as the cathode in an electrolyte and the voltage and current density are selected so that the metal is deposited on the raised parts of the plate. In order to protect the image, it is coated with a material which remains on the plate during printing, such as a varnish which is insoluble in the ink, and particularly a varnish containing shellac or phenol-formaldehyde resin which is rendered harder by heating, or a colour containing resin ; alternatively, the image can be applied to a plate formed of a metal such as copper, brass, or iron which is not attacked by the etching-agents, the image being also coated with varnish if desired, and the non- printing parts being coated electrolytically with a water-retaining metal such as zinc or aluminium. The electrolyte contains a solution of a base of the pyridine series on their compounds ; for example, an aqueous solution of zinc chloride and pyridine containing sufficient hydrochloric acid to impart a pH value of 3 to 5.5 may be used, together with a current density of .2-.6 amp. per sq. dcm. The process is applicable to the preparation of offset intaglio printing-surfaces for use in the processes described in Specifications 304,685 and 321,086, [both in Class 100 (ii), Printing processes &c.].

Abstract: 385,346. Induction relays. LANDIS ET GYR SOC. ANON., 1, Hofstrasse, Zug, Switzerland. Aug. 12, 1931, No. 22823. Convention date, Sept. 2, 1930. [Class 38 (v).] An induction relay which is operable in accordance with a particular frequency of current superimposed on the mains has a series resonant circuit 7 consisting of a condenser 9 and inductance 11 energized from the supply, the winding 11 being placed on the return limb 4 of a two-limbed core 1 in the air gap 5 of which is placed the induction disc 6. On one of the limbs 2 is placed a winding 12 inductively related to the winding 11 and tuned by a condenser 11 to the superimposed frequency, the second limb 3 being unwound. The interaction of the fluxes produced in windings 11, 12 cause the rotation of the disc when current of the predetermined frequency is superimposed on the mains. The relay may be employed in conjunction with switches, multiple-tariff meters, or electric clocks to perform operations therein in response to currents of a predetermined frequency superimposed on supply mains.

Title: Improvements in and relating to pianofortes provided with devices for producing tremolos
IPC: G10C3/24
Filed: 1931-08-13
Abstract: 388,060. Pianofortes. MOOR, E., Mont PÚlerin-sur-Vevey, Switzerland. Aug. 13, 1931, No. 22850. [Class 88 (ii).] A device for producing tremolos in pianofortes comprises a system of levers connected with the keys and engaged or disengaged by a pedal or kneelever so as to bring rotary catches into or out of action. The hammer 10 is normally actuated from key 1 by a pushing member 3, lever 9 and rod 10a. Depression of a pedal 8 actuates levers 6 through a bell-crank 7 to draw the members 3 forward out of action, and at the same time to draw members 4 forward under arms 11 carried by the levers 9. Depression of a key 1 then carries the arm 11 into the path of a rotating catch 13 to produce the tremolo. Volume during tremolo may be controlled by another pedal moving the rotary shaft 12 transversely in guides. The shaft 12 may be rotated at a variable speed, and may be divided so that the tremolo may apply only to certain octaves. The members 4 may be fixed on the key-levers, in which case a stop, normally in position under the keys, is removed by the tremolo pedal, allowing the keys to be depressed more deeply so as to carry the members 4 into a higher position where they will actuate the arms 11. The invention may be applied to pianofortes with a double keyboard or with an octave coupling.
