Title: Sheet sorting apparatus
IPC: B65H39/115
Filed: 1972-05-23
Abstract: 1365399 Delivering sheets; collating apparatus XEROX CORP 23 May 1972 [24 May 1971] 24128/72 Heading B8R In a sheet sorting apparatus comprising upper and lower sorting assemblies 53 and 55 to which sheets may be selectively diverted by a switch 135, the drive of sheet transport rollers 67 is derived from either of the independent drives of upper and lower sorting assembly transport belts 117 and 71. Sheets are directed sequentially into the trays 59 of either of the sorting assemblies by deflectors 123 which cause sheets to be moved from the associated transport belt 117 or 71 into the trays. As a sheet enters a tray, it temporarily interrupts the light to a photo-cell 80 or 127 so causing the adjacent deflector to direct the next sheet into the next adjacent tray. Sheets are directed to the upper sorting assembly by way of a vertical transport belt 131. Each of the belts 117 and 71 is driven by an independent motor 167 and 153 respectively. The shaft of transport rollers 67 carries overrunning clutches 231 and 233 which are arranged to be driven from the upper and lower sorting assembly transport belts 117 and 71 respectively. With this arrangement the rollers 67 may be operated by motor 167 or motor 153 depending upon which of the sorting assemblies is receiving sheets at a particular moment. The transport belts 117 and 71 may be housed in pivoted lids 141 and 137 thus enabling the belts to be lifted for the removal of jammed sheets.

Title: Device for controlling hydraulic fluid
IPC: F15B13/01
Filed: 1974-06-04
Abstract: 1443650 Valves VAN DOORNE'S BEDRIJFSWAGENFABRIEK DAF BV 4 June 1974 [3 July 1973] 24677/74 Heading F2V [Also in Division Fl] The return of fluid from a ram 24, Fig. 1, to a pump 9 is controlled by a device comprising a piston 7 and valves 3, 4 which ensures that the rate of return of fluid is proportional to the pressure exerted by the pump. To tilt a cab 29 from the position shown conduit 17 is connected to the supply side of the pump 9 and fluid flows past the valve 3 and into ram 24. Pressure in a chamber 6 displaces the piston 7 to the left so that the valve 4 is opened by a tapered rod 8. This permits return of fluid at a rate determined by the tapered rod 8. When the cab goes overcentre its rate of descent is still controlled by the pump pressure since this is required to hold the valve 4 open by displacing the piston 7. If the pump is stopped the valve 4 closes and the cab is arrested.

Title: Alkaline Earth Metal Sulfonates
IPC: C10N30/04
Filed: 1967-05-26
Abstract: 1,166,744. Alkaline earth sulphonates. STANDARD OIL CO. 26 May, 1967 [27 May, 1966], No. 24705/67. Heading C2C. The invention relates to an improvement in the process of producing an over-based alkaline earth metal sulphonate comprising reacting a preferentially oil-soluble sulphonic acid with an excess of a basic alkaline earth metal compound, preferably a basic magnesium compound e.g. oxide in the presence of an alkanol and having from 1-3 carbon atoms passing carbon dioxide through the reaction mixture whereby the over-basing is carried out in the presence of an amine preferably in an amount from 0.05 to about 10% by weight of the basic alkaline earth metal compound. In an example to polypropylene alkylated benzene sulphonic acid were added xylene, magnesium oxide and methanol and the neutral magnesium sulphonate obtained was mixed with ethylene diamine, magnesium oxide and water and the mixture blown with carbon dioxide. After removal of methanol by heating, water was added and after heating more water was added and the mixture blown with carbon dioxide. The mixture was heated to remove water and xylene and filtered to give the sulphonate. Other examples are given.
Patent GB-771650-A (GB)
Title: A process for preparing monocyclopentadiene by thermal depolymerization of dicyclopentadiene
IPC: C07C13/39
Filed: 1955-08-29
Abstract: Monocyclopentadiene is prepared by subjecting dicyclopentadiene to thermal depolymerization in the liquid phase in the presence of an auxiliary liquid boiling above 250 DEG  C., at a temperature so close to the boiling-point of the auxiliary liquid that the dimer concentration in the liquid phase is less than 10 per cent, and continuously removing the monomer in the gaseous state.  The auxiliary liquid must have only slight solvent power for the monomer and dimer under the reaction conditions.  Liquids specified are high-boiling paraffin hydrocarbons such as pentadecane, hexadecane and octadecane and petroleum fractions such as gas oil or spindle oil fractions.  To avoid repolymerization, the gaseous monomer may be rapidly cooled to below - 10 DEG  C., or may immediately be converted into derivatives, e.g. by reaction with acetylene to form 1,4-methano-2,5-cyclohexadiene, or by reaction with chlorine to form hexachlorocyclopentadiene.  Reaction temperatures of 250-300 DEG  C. are referred to.  During the reaction, part of the bottom liquid may be withdrawn, impurities separated by distillation or by precipitation of the polymers on cooling, and the auxiliary liquid recycled.  When impure dicyclopentadiene is used in the reaction, it may first be purified, e.g. by distillation.  Specification 612,893 is referred to.
Patent GB-797037-A (GB)
Title: Improvements in or relating to fuel injection equipment
IPC: F02M59/08
Filed: 1956-08-14
Abstract: 797,037. Fuel injection pumps. BOSCH GES., R. Aug. 14, 1956 [Aug. 19, 1955], No. 24784/56. Class 102(1). A fuel injection pump for the selective operation of an internal combustion engine with liquid fuel alone or with gas and a relatively small quantity of liquid ignition fuel embodies two pump pistons 3, 6 in which the piston 3 is adapted to supply the main fuel quantity when working with liquid fuel alone and the piston 6 which has a smaller swept volume is adapted to supply the ignition fuel. Both the pistons supply a common injection nozzle of the engine through a common pressure valve 11. The pistons 3, 6 are coaxially mounted for common reciprocation and rotation. The fuel inlet 19 communicates with the pump chamber 23 through ports 20, 21 and via an axial passage 22 and port 24 with the pump chamber 32. The piston 3 has a control groove 26 and a passage 28 which in one angular setting of the pistons 3, 6 connects the pump chamber 23 to the port 21 so that the piston 3 is inoperative. In this angular setting of the pistons fuel in the chamber 32 lifts the valve 11 when the port 24 is closed and a small quantity of fuel is delivered to the injector until a groove 30 in the piston 6 communicates with the port 24 thereafter fuel in the chamber 32 passes via the passage 33, 31 and the groove 30 back to the port 24 and the valve 11 closes. In the second angular setting of the pistons the groove 28 is not in communication with the port 21 so that the pistons 3, 6 are operative when piston 3 has closed the port 20, 21 until the control edge 26 becomes operative. Fuel is pumped from the chamber 23 via the passage 22 and the port 24 and a groove 35 in the piston 6 through the chamber 32 and through the valve 11 thereby full fuel injection takes place. The specification states that by closing the upper end of the groove 35 the piston 6 may make a preliminary injection before the piston 3 closes the port 20, 21.

Title: Improvements relating to the transmission and reception of optical images
IPC: G02B27/00
Filed: 1961-07-10
Abstract: 948,808. Optical apparatus; photographic processes. OPTISCHE INDUSTRIE DE OUDE DELFT N. V. July 10,1961 [July 9, 1960],No. 24890/61. Headings G2C and G2J. In a system for transmitting and receiving an image of an object, the transmittion means comprises a device for focusing an image on the object in a plane, dispersing means in the light path to the plane so that each elemental area on the object is reproduced as a spectrum at that plane, the spectra corresponding to different elemental areas of the object having relative positions in the plane corresponding to the relative positions of the areas in the object, aperture means in the plane to pass light incident thereon within an area corresponding in size to the elemental bias in the object so that of each of the spectra a different portion will fall within said area of the plane and be passed by the aperture means, and means for combining the light passed by the aperture means for transmission to the receiver. The latter is preferably similar to the transistor but having its components reversed in arrangement and operation. As shown in Fig. 1, elemental areas such as 9,14,15 of an illuminated object are focused by system 4, 5, 6 on to a plane 7 having an aperture 8 of a sign corresponding to that of each elemental area. The elementary light beams such as beam 3 from elemental area 9 are concentrated by mirror 4, dispersed in a horizontal plane by echelon grating 5 and then dispersed in a vertical plane by concave grating 6 so that elemental area 9 for instance, is reproduced as a spectrum 10 on the plane 7. In that way only one colour, representing area 9, will pass through the aperture 8. Similarly, the other elemental areas 14,15 will be reproduced as spectra in different rotating positions so that a different colour, representing each of the other areas, will pass through aperture 8. These colours are combined in a transparent cable 16 for transmission to a receiver comprising collimating mirror 17, echelon grating 18 and concave grating 19 whereby the elemental areas of the object are reproduced on a screen or film 20. As the form is described in which the transmitter is a prism spectroscope having a screen on which the different spectra are reproduced, this screen having the apertures separated by distances corresponding to nearly one-third of the length of each spectra so that each aperture receives a part of each spectra. A transparent cable with three branches at one end is positioned with one branch behind each aperture transmits the image to a receiver of similar form to the transmitter whereby the image is formed in natural colours on a screen or film.
