Abstract: 348,894. Addressing -machines. WADE, H., 111, Hatton Garden, London.- (American Multigraph Co. ; Kelley Avenue, Cleveland, Ohio, U.S.A.) May 23, 1930, No. 15966. [Class 100 (ii).] In an addressing-machine having a magazine for a stack of address-plates and mechanism for feeding the lowermost plates in succession to printing position, automatically actuated escapement mechanism is provided which allows the whole stack to descend on to the feed device and subsequently supports all but the lowest plate, which is left resting on the feed device. Interference of the plate being fed with that immediately above it and dislocation of the index tabs is thus avoided. The machine shown comprises an impression pad 24 carried by an oscillating arm 20 adapted, through links 26, 27, to reciprocate a plate-feed device comprising parallel bars 30 provided with shoulders adapted to feed the bottom plate from a magazine 12. A spring plate 40 is fixed by screws 41 to each side of the magazine and extends through a slot 42, and each plate has an inturned wedge-shaped lip 43. At the end of the feed stroke, projections 35 on the bars 30 engage cams on the lower ends of the plates 40 so as to spring the plates outwardly and allow the stack of address-plates to drop down on to the bars 30. On the return stroke, the plates 40 are released and move inwardly so that the lips 43 engage between the two lowest addressplates A, A<1>, and lift the stack clear of the lowest plate A, which is advanced at the next feed stroke.

Patent GB-349311-A (GB)
IPC: A23B7/16
Filed: 1930-05-29
Abstract: Fruit such as oranges, lemons, tangerines, grapefruit and other citrus fruit, and tomatoes, apples, and pears, and vegetables are preserved by applying to the surface thereof a mixture, in fluid condition, of a waxy material or materials of relatively low melting point and a waxy material or materials of substantially higher melting point to give a substantially uniform film having a melting point higher than paraffin wax and not sufficiently thick to prevent breathing of the fruit &c.  Amongst the materials of low melting point used are paraffin wax, ozokerite, ceresin and other mineral waxes and Japan and other non-mineral waxes, and the materials of high melting point include carnauba, candelilla, montan and China waxes.  A mixture of carnauba and candelilla waxes is advantageously used, 25 per cent or less, preferably 5-20 per cent, of carnauba wax being present. Examples of mixtures of paraffin wax with candelilla wax, which has preferably been refined to remove the resinous constituent causing tackiness, and with montan wax are given.  The low melting point ingredient may be a mixture of Japan and paraffin waxes and the high melting point ingredient a mixture of China and carnauba waxes.  The temperature of application is substantially above that at which the waxy mixture melts.  The mixture may be applied to the fruit by brushing on, e.g. in apparatus comprising parallel rotary brush rollers between which travels longitudinally an endless flexible brush element at a speed which can be adjusted independently of that of the brush rollers.  The material may be sprayed on the fruit just as it enters the brushing unit.  The spray may be operated by heated compressed air and the material may be supplied thereto from a heated tank.  The brushing unit is enclosed in a heat-insulated housing the temperature within which is kept at about 76-104 DEG  C., preferably 93-104 DEG  C., by thermostatic control.  Uniform coating is obtained by creating a thin mist of material within the housing and by the action of the brushes, the coating treatment taking at least 5-10 seconds, preferably 15-25 seconds.  The Specification as open to inspection under Sect. 91 (3) (a) comprises also subjecting the fruit to a washing and cleansing treatment to retard blue mould and other forms of decay, prior to the coating.  An alkaline cleansing agent such as borax, or sodium carbonate, caustic soda or other comparatively strong alkali may be used.  The small amount of alkaline material left on the skin improves the waxy coating subsequently applied.  This subject-matter does not appear in the Specification as accepted.

Abstract: 1,016,688. Fluid actuated logical circuits. SOC. D'ELECTRO CHIMIE D'ELECTROMETALLURGIE ET DES ACIERIES ELECTRIQUES D'UGINE. April 30, 1963 [May 4, 1962; Nov. 13, 1962; Dec. 14, 1962], No. 16947/63. Heading G4B. [Also in Division G3] Fluid valves are designed for the performance of logical functions. In the not element of Fig. 1, the presence of an input signal jet at orifice E prevents the flow of a reference jet at input A to output S. Such elements can be connected in series to give a nor circuit, or arranged as in Fig. 4 to give an or circuit: there is an output S5 only if any of E1 to E4 are present. Fig. 9 (not shown) shows a bistable circuit, with inputs A1 and A2 present, either S1 or S2 can give a steady output. By applying signal pulse m to circuit 93, S1, if present, is cut off and S2 generates. A pulse a applied to circuit 94, by interrupting A2, cuts off S2 and restores S1. Fig. 13 (not shown) shows an or circuit. The ball B1 is raised from its seating to permit input A to flow through orifice S only by the presence of at least one signal E1 to E3. By arranging that the raising of ball B1 blocks flow between A and S, as in Fig. 1, a nor circuit is provided (Fig. 12, not shown). Fig. 15 (not shown) shows a selector circuit. If input E is present, output is from orifice S2, otherwise orifice S1, provided that inputs A1 and A2 are present. Combinations of the above circuits are described in the Specification. Depending on the sizes of the various valve passages, the valves can have an amplifying effect.
