Title: Process for manufacturing thermoplastic granules
IPC: B01J2/00
Filed: 1960-08-04
Abstract: <PICT:0909147/IV(a)/1> <PICT:0909147/IV(a)/2> Short length artificial filaments are produced by melt spinning a synthetic organic thermoplastic material such as a polyaminocaproic acid from a spinning head 3 (Fig. 1) into a quenching bath of water 5 in the form of a bundle of filaments 4 which are drawn over deflecting members 7 and 8 to a filament cutting device 10. The deflecting member 7 consists of a tube 11 (Fig. 2) closed at both ends and having a longitudinal slit-like opening 12 provided at each end with a projecting pin 13. Opposite the opening 12 the tube 11 communicates with a cold water supply line 14 provided with a control valve 15. The thickness and the number of filaments 4 on the one hand and the distance between the pins 13 on the other are so related that the filaments contact one another as they are drawn over the slot 12 of the deflecting member 7. By adjusting by means of the valve 15 the force with which cold water is discharged from the slot 12 against the filaments 4 the latter can be caused to adhere to each other slightly. Short ength filaments thus produced have a very uniform size and shape, rendering them suitable for the melt spinning of continuous filaments and for injection moulding.

IPC: G03D13/00
Filed: 1967-07-29
Abstract: A printing and processing apparatus comprises a first enclosure 11 housing a lamp 18 which serves as a source of both light and heat. The light passes through a condenser system 22 and through an aperture 17 in the wall 16 of the enclosure. Across aperture 17 are mounted side rails (28, Fig.3, not shown) for holding a slide mount (29) carrying the negative or transparency. A second enclosure 35 has on one wall 47 a pair of side rails 45 into which can be slid a holder for a light-sensitive sheet, which is exposed through an aperture 48 in wall 47. On the opposite wall 36 of enclosure 35 a mounting 33, 34 carries an objective lens. The two enclosures 11, 35 are connected together by rods 37 which allow relative movement between the two, so that the magnification may be varied. Within enclosure 35 a mirror 39 is mounted on an axial pivot 40, so that it may be swung entirely out of the light path when a print or enlargement is to be made. When it is interposed in the light path, as shown in Fig. 2, the image of the negative is reflected on to a viewing screen 42, and to facilitate viewing, this part of the apparatus is tilted as shown. (The apparatus may be used as a contact printer by putting both negative and light-sensitive sheet together into the holder which slides between rails 45.) The apparatus is envisaged as being used for making prints which can be developed by heat only, and the first enclosure 11 is adapted for this purpose. It has an arcuate metal top 12, on which the exposed sheet is placed and held in close contact by a transparent screen 14, hinged to the top along one edge and having a handle 15 at the other edge. Thus the sheet is developed by heat from lamp 18, and the degree of development can be controlled by visual inspection through the transparent screen 14.

Patent ES-347238-A1 (ES)
Title: Heating and Cooling of Passenger Compartments
IPC: G05D23/24
Filed: 1967-11-16
Abstract: In a method of air conditioning passenger compartments particularly of railway trains, a measured temperature is compared with determined upper, intermediate, and lower temperature references such that at the upper temperature a cooling unit is prepared for operation and a heating unit disabled, at the lower temperature a heating unit is prepared and a cooling unit disabled, the output of either unit at any one time being controlled as a function of the measured temperature in relation to the intermediate reference. The heating and cooling units may be subdivided and one or more parts introduced in turn with a time delay. A temperature detector 7 controls a relay 10 operating contacts 10 1 and hence a relay 12 controlling a heating unit (not shown). As the temperature rises another detector operates another relay 11 closing contacts 11 1 which through already closed contacts 10 2 energizes a relay 15 which is held over its own contacts 15 2 contacts 15 1 disabling the relay 12, and contacts 15 3 energizing through contacts 10 3 a relay 16 which prepares a portion of a cooling unit. Simultaneously a timing relay 18 2 is energized which after a determined delay opens its own contacts 18 1 and closes contacts 18 2 energizing a relay 17 preparing a second portion of the cooling unit. The cooling unit is then controlled by detector 7 until a low temperature is sensed by a detector 6 when relay 9 is de-energized, opening contacts 9 1 which through relay 15 disconnects the cooling unit and prepares the heating circuit through contacts 15 1 . A high temperature safety cut out 13 may be provided, and a thermostatic switch 14 responsive to low outside temperature may disable the cooling circuit.

Title: Continuous process for the production of alfin polymers
IPC: C08F10/00
Filed: 1968-10-03
Abstract: Polymers are obtained by continuously blending alfin catalyst, monomer, solvent (or diluent) and molecular weight moderator, continuously polymerizing, continuously separating volatile materials (i) by flashing at a reduced pressure and elevated temperature at the end of polymerization and in the absence of water and of a catalyst deactivator, and. (ii) quenching the reaction mixture in water, and steam distilling the resulting dispersion, and thereafter recovering monomer and solvent and recycling them, and washing and drying the alfin polymer. The flashing step prior to watertreatment enables solvent free of acetylene and cyclopentadiene impurities to be obtained, since the latter are liberated from their sodium salts on contact with water. Suitable monomers are conjugated dienes and alkenyl aromatic compounds, the polymerization of butadiene and of isoprene, and the copolymerization of butadiene with styrene or with isoprene (exemplified) being particularly mentioned. Two detailed flow diagrams (not shown) are provided.

Title: Improvements in or relating to resiliently mounted seats, particularly motor vehicle seats
IPC: B60N2/50
Filed: 1969-05-22
Abstract: A seat shell, e.g. for a motor vehicle, in which the spring suspension resistance is varied to suit the weight of the user is guided by a parallelogram linkage positioned at the side of or directly below the seat and having a lever 10 formed as a housing 10a, 10b for parallel rods 20, 21, forming an inner lever 11, and links 13, 14 each having one end mounted in a bearing bush 12 at each end of the housing and rotationally fast with a seat holder 23 and a fixed bracket 24, respectively. Each of the links 13, 14 has two parallel arms 17, 18 which are pivotally connected by the rods 20, 21 on each side of a pressure cylinder 26 which has an edge 33 displaceably supported on a web surface 34 of the link 14. The cylinder has a ball head 37 pivotally mounted in the housing and is urged upwardly, to raise the point of contact between the edge and the web towards the pivot axis of the link 14, by a leafspring 46 one end of which is fastened to the pressure cylinder and the other end of which slides on the rods 20, 21. The effect of the spring is overcome by a cam 40 which is operable by a spring- loaded knob 43 engaging apertures 45 in a plate on the housing for step-by-step adjustment of the edge 33 along the web surface 34, the position of maximum resilient support for a heavy user being as shown in Fig.3. The seat shell is movable in the direction opposite to the direction of loading to a raised position to accommodate a standing operator, the surface 34 being moved away from the edge 33 to a position 47 in which it is locked by engagement of a nose 46a on the spring in a notch 48 in the rod 21. The angular position of the link 14 and hence the height of the seat is adjusted by elongation of the pressure cylinder 26 by rotation of an adjusting wheel 31 to rotate a screwthreaded portion of the ball head 27 in a threaded portion of the piston rod 26a during which adjustment the distance of the edge 33 from the pivot axis of the link 14 and hence the weight resistance of the seat remains substantially unchanged. In modifications, the cam 40 is replaced by an adjusting screw having a transverse end piece in sliding contact with the cylinder wall, or, for use with a seat shell guided at its rear by rollers in an upright guide and supported on its underside on a guide rocker. The rear end of the rocker is supported in a stationary housing on a link corresponding to the link 14, the link 13 and the inner lever being dispensed with and the free end of the spring sliding on the inner surface of the housing. A screw 66 on the housing is lockable in adjusted position along a slot in a base-plate for adjustment of the seat therealong and, if the plate is curved, adjustment of the inclination of the housing.
