A mechanism for feeding sheets simultaneously to multiple platens of a press comprises a loader, movable towards and away from the press, having at levels corresponding to those of the press interlocking stationary and movable trays, with projections on the movable trays to displace sheets from the loader to the platens. Fig. 14 illustrates apparatus for feeding plywood, hardboard or chipboard to verticallyspaced platens 18 of a hot-press. The loader is in two parts, part A comprising the frame of the loader mounted on wheels 7, and a plurality of vertically spaced trays 1 with stops 4, and part B comprising a corresponding plurality of movable trays 8 each having pusher members 9 at their ends remote from stops 4. In operation, sheets are first loaded manually on each stationary tray 8; the loader is then moved on its wheels up to the press, the stops 4 being located in the desired positions with respect to the press; a chain drive 13 is started simultaneously at each level and the movable trays 8 are moved forward over the platens 18, the pusher members 9 causing the sheets to be displaced from the stationary trays 1; the chain drive then retracts the movable trays 8, but the stops 4 prevent the sheets from returning therewith and the sheets are thereby deposited on the platens 18. The pusher member 9 on trays 8 project through the corresponding stationary trays 1, which are formed with spaces between their longitudinal members.

Abstract: 1469017 Measuring diameter electrically; paper web splicing apparatus RENGO CO Ltd 17 Oct 1974 [1 June 1974] 45090/74 Heading B8B [Also in Division G1] A paper web roll diameter sensing device for use with paper splicing apparatus comprises: a guide roller 20, Fig. 1, rotatable in contact with a web W being unrolled from a web roll, a first pulse generator responsive to rotation of the guide roller, a second pulse generator responsive to rotation of the web roll; and electrical means for signalling when the pulse rates of the first and second generators are substantially equal. An expiring web roll 10, Fig. 1, causes a pin 22 to operate a proximity switch 21 providing a pulse Y n  for every rotation. The web W runs over the guide roller 20 which drives at a predetermined velocity ratio a disc 12 carrying a pin 13 operating a proximity switch 11 to give a pulse X n  for every rotation. Pulses X n  and Y n  are applied to a circuit 3, Fig. 3, in which a selector 31 comprising a bi-stable sorts the pulses X n  into an odd-ordered train X o  and an even-ordered train X e . A discriminator 32 inspects the pulses, and, after a Y pulse has alternated with an X pulse consistently during the passage of at least six consecutive X pulses, provides an output signal for the splicing to commence As the expiring web roll 10, Fig. 2, approaches the predetermined diameter, an auxiliary splicing roller 72 is moved to a position under a front splicing roller 61. When the circuit 3 provides the signal, a drive 82 starts a replacement web roll 30 rotating counter-clockwise. When a proximity switch PS responsive to rotation of the web roll 30 gives a second pulse, a main frame 5 is rocked to lower the auxiliary splicing roller 72 into contact with the web roll 30. The leading end of the web of roll 30 carries double-sided self-adhesive tape on both faces, causing one face to wrap itself partly around the auxiliary splicing roller 72 until the other face is spliced to the web W as it passes through the nip between the rollers 61 and 72. On the next signal from the switch PS the drive 82 is disengaged from the web roll 30, and knives 93, 94 cut-off the expiring web. When the web roll 30 is nearly exhausted, a similar sequence of operations takes place, using a drive 81, an auxiliary splicing roller 71, and a rear splicing roller 62 now displaced to the front end 51 of the frame 5.

The first and second conveyer means may comprise a single roller conveyer having roller assemblies each composed of a double conical member 20, and a member 21 having a frusto conical external surface 22 and a frusto-conical internal surface into which the member 20 abuts. The member 21 is adjustable along the drive shaft 16. There are a plurality of inverting elements 26, each mounted on an arm 27 swingably supported by parallel arms 29 mounted on shafts 30. When the shafts 30 are rotated the elements 26 raise a section against a stop 36 on a screw threaded shaft 37, the stop pushing the section off the elements. The rollers feed the sections on to a plurality of cantilevered platforms (40) and against a pendulum stop. The platforms are transversely movable to build up a layer of sections. A layer of inverted sections are formed after each layer of, or each group of layers of, non-inverted sections. Each platform is mounted on a screw threaded rod which is rotated, to lower the platform, during the first half of each backwards and forwards movement by a pair of racks (69, 70). A free-wheeling clutch (66) prevents raising of the platform during the second half of the each transverse movement. A chain conveyer may remove the stack from the platforms. The platforms are raised by a hand wheel with the clutch being disengaged.

Abstract: 1474864 Treating grape skins in wine-making J S BIANCHII 31 Oct 1975 45462/75 Heading C6E  A fermentation process for making coloured wine from grapes having coloured skins involves the steps of de-stemming and crushing the grapes, dejuicing and pressing the de-stemmed and crushed grapes to separate the juice and pulp from the skins, adding yeast to the juice and pulp to cause fermentation thereof into wine, subjecting the skins to the action of an aqueous mixture of citric acid and an acid selected from hydrochloric, sulphuric and phosphoric acids to provide an aqueous coloured acidic extract, partially neutralizing the coloured acidic extract with a non-toxic neutralizing agent e.g. sodium carbonate, separating the skins from the partially neutralized extract and adding the coloured, partially neutralized aqueous extract to the juice and pulp prior to completion of the fermentation, preferably at about 60% completion. The grape juice and pulp of a desired consistency are fermented in a vat providing free communication with the ambient atmosphere whereby carbon dioxide and heat may flow freely from the fermentation. The skins are preferably treated with a hot 0À1 N aqueous mixture of three parts, by weight, of a high purity, iron-free hydrochloric acid and one part of citric acid. The acidic mixture is heated to a temperature between 120‹ and 160‹F prior to contact with the skins and one gallon of it is used for each ten pounds of skins. The partially neutralized coloured aqueous extract may be subjected to vacuum distillation to deepen the colour prior to addition to the juice and pulp. The skins separated from the partially neutralized extract may be further extracted with 0À4 N hydrochloric acid. The resulting further extract, after separation of the skins, has sugar added to it, the sweetened solution is fermented by yeast and the alcohol produced distilled to provide a brandy base.

Abstract: 1,105,818. Automatic steering control. SOCIETE FRANCAISE D'EQUIPEMENTS POUR LA NAVIGATION AERIENNE. Oct. 27, 1965 [Dec. 16, 1964], No. 45583/65. Heading G3R. In a system for automatically controlling the heading of a vehicle, the difference between the actual heading and a desired course results in rotation of a shaft which operates the rotor of an electrical signal generator through a non-linear coupling which ensures that rotation of the rotor never exceeds 180‹ despite a greater angle of rotation of the shaft. As applied to an automatic pilot, Fig. 2 (not shown), a synchronous electrical receiver 2 of compass signals is positioned by a follow-up servomotor 5 and operates a compass card 1. A pointer 8 indicating a desired course is manually rotatable relative to the card by a knob 12 operating through a differential gear which is also driven by motor 5. A cam 20 fixed to pointer 8 operates a transducer 14 to produce electrical signals for automatic course correction. Cam 20, Fig. 3 (not shown) has a spring-connected auxiliary segment 24 so arranged that, for a 200‹ movement in either sense, the transducer moves through less than 180‹ to a maximum deflection in a corresponding sense during the first 30‹ of movement of the cam and maintains that deflection during the remaining 170‹ of movement.
