Title: Improvements in or relating to duplicating or manifolding sheets, pads or books
IPC: B41L1/22
Filed: 1934-10-08
Abstract: 440,835. Manifolding -books; carbon papers. GILBERT, A., 101, Goswell Road, London. Oct. 8, 1934, No. 28732. [Class 16] [See also Group XVI] In a duplicating or record sheet provided with a carbonized surface, the carbonizing-material is arranged in side-by-side bands or stripes, adjacent bands or stripes being of contrasting colour. The arrangement is such that each of the carbon entries made therewith is preferably in two or more contrasting colours to prevent fraud. In the form shown, a pad of record sheets, each sheet 1 having one side coated with carbon and the other side ruled with longitudinal and transverse lines, is bound into a cover 5, 6. The carbonized surface may comprise longitudinal contiguous bands of colours, such as red and black, or the colour bands may extend obliquely across the sheet, or may be zigzagged down the sheet. The bands of colour may be separated to a small extent, and may not extend the full length or breadth of the sheet. Each sheet may have two spaced filing-perforations 14, whereby the sheets, either in pad or loose form, may be used in a duplicate-writing appliance, such as that described in Specification 383,717; further perforations 15 may also be provided in each sheet for use in the duplicate-writing appliance described in Specification 309,248, [Class 16]. Each sheet may have a counterfoil 2 from which the main portion may be detached along a line of perforations 3. Record cards may be placed beneath the record sheets to receive coloured duplicate entries thereon, or alternate uncarbonized duplicate sheets may be included in the pad. In order to simplify the detection of the removal of record sheets from the pad, one edge thereof, preferably the unbound lower edge, has one or more oblique coloured bands or lines printed &c. thereon. Instead of applying the colour bands of carbon to the back of a record sheet, they may be applied to the back of a sheet which is to serve merely for duplicating purposes.

Abstract: 1,034,287. Dry closets. GADELIUS & CO. A.B. July 14, 1964 [July 15, 1963], No. 29007/64. Heading E1C. A dry closet comprises a closet pan 1 having a discharge opening 12, and a cylinder 4 where shown, in which is a plunger 5 which, when retracted, uncovers a receiving chamber therein in direct communication with the opening 12, the cylinder's discharge end being then put into communication with a soil pipe 15, the plunger 5 acting to eject waste matter through the cylinder when moved from its retracted to an extended position. The plunger 5 has a sealing member 6 and, when retracted, has a clearance between it and the cylinder 4, permitting its rear end to be slightly lifted under the action of a spring 18, so that the cylinder's lower surface is scraped clean when the plunger 5 acts to eject.

Title: Apparatus for the simultaneous fanning and pasting of sheets for book-binding without wire sewing or the like
IPC: B42C9/00
Filed: 1949-11-14
Abstract: 681,858. Bookbinding. ABBEY, A. (Ehlermann Kommandit-Ges. Dipl. Ing. H.). Nov. 14, 1949. No. 29101/49. Class 16. [Also in Group XXV] Apparatus for simultaneously fanning and pasting. a block of sheets 56 for binding into a book, 'comprises a book-clamp 55 (see Group XXV) mounted to oscillate about a horizontal axis above an adhesive-applying roller 34 so that the edges of the sheets are fanned as the adhesive is applied ; adhesive is supplied to the roller 34 from an underneath roller 35 dipping into a receptacle 36. As shown, the shafts of the rollers 34, 35 are coupled by pinions 40, 41 for reverse rotation, and are turned by a crank handle 43. Situated to one side of and below the cylinders is a shaft carrying at one or each end a pinion 37 by which it is driven from the cylinder 35 through a pinion 14. An adjustable connecting-rod 45 extends between each pinion 37 and a pinion 47 on a support 49 adjustable on a pillar 491. Each pinion 47 gears with a pinion 51 mounted on a support 49 and carrying a suspension member 53. The clamp 55 is mounted between the two suspension members and is oscillated by the intermediate gearing from the shaft of cylinder 35. The distance between the clamp 55 and the cylinder 34 can be varied for different-width books by adjusting the connecting-rods 45 and the supports 49. To obviate undesirable pasting of the surface of the outermost sheets, gratings 57, 58 may be provided which permit contact of the sheets with the roller 34 only at the uppermost part of the roller. The amount of paste applied may be varied by adjusting the spacing of the rollers 34, 35 or by means of doctor rollers co-operating with the roller 34. In a modification, instead of pinion drives, frictionally-engaging discs are employed. If the block of sheets is not composed exclusively of single or double sheets of the same kind, then blades or tongues may be inserted between the sheets to ensure uniform fanning of the block.

Title: Improvements in or relating to pump and flow regulators
Inventor: DRUTCHAS GILBERT HENRY
IPC: F04C14/26
Filed: 1964-07-15
Abstract: 1,077,511. Power-assisted steering. TRW. Inc. July 15, 1964, No. 29128/64. Heading B7H. [Also in Divisions F1 and F2] In vehicle power-assisted steering where it is required to reduce the flow of hydraulic fluid at high speeds where the steering effort is small, flow from the outlet (16), Figs. 1 and 2 (not shown), of a pump (10) takes place via an orifice (54) through the interior of a spool valve (46) (see Division F2) which regulates the amount of by-pass fluid returned through a passage (14). The pump pressure is communicated through a groove (52) to the end of the spool which is thereby responsive to the pressure drop across the orifice to open the by-pass as the speed increases. To achieve the required flow reduction, the valve is increasingly biased in the opening direction as a function of its travel. In the embodiment of Figs. 1 and 2, the spool is increasingly attracted toward a fixed magnet (60) as it approaches open position. In another embodiment, Figs. 3 and 4 (not shown), the pressure difference varies with valve position. An additional flow orifice (155) in the spool opens on to a rounded shoulder of the spool adjacent a land thereon which controls the bypass. This orifice is inclined toward the open end of the spool. In open position, the bypass flow past the opening of the orifice results in an increase of the pressure drop across it, whereby the pressure difference biasing the spool in opening direction is increased

Abstract: 276,199. Wehling, A. Nov. 18, 1926. Automatic speed control - indicating setting of controlling apparatus. - The throttle-controlling mechanism is connected to a set of stop members each corresponding to a definite throttle opening and being made operative one at a time by electromagnetic means, so that the throttle-opening, and therefore the speed, is limited to that set bv the particular stop operated. An indicating device shows which speed limit has been selected. The throttle 4 is controlled by a pedal 1 connected also by links 3, 6 to a spindle 7 carrying cams 14 set in step fashion. Each cam operates in conjunction with a stop arm 9 normally held out of contact by a spring 13 but brought into the path of the cam by an electromagnet 17 when the magnet circuit is closed by a switch handle 8. The switch carries contacts each of which corresponds to one of the magnets 17, so that when the switch handle is on one contact the corresponding magnet is energized and its stop 9 actuated, while all the other stops are inoperative. Corresponding to each magnet and stop there is a secondary magnet 18 the circuit of which is closed at 11, 23 by the stop 9, each of these magnets when energized bringing into view an arm 16 showing the speed limit corresponding to the particular stop selected by means of the switch 8.
