Title: Photocomposing device
Inventor: KOHLER WOLFGANG
IPC: B41B21/26
Filed: 1966-11-11
Abstract: 1,142,677. Photographic type-composing apparatus. LINOTYPE, G.m.b.H. 11 Nov., 1966 [15 Nov., 1965], No. 50613/66. Heading B6W. In a photocomposing device comprising character transparencies arranged in one or several rows the character image beam required is selected by optical deflecting means moved into, the path of the beam, and a condenser lens is arranged between each character transparency and its associated deflecting means to direct the character image to a second deflecting means and thence to a second condenser lens whose focal point is in the plane of the recording medium. Character patterns 6-9 are mounted exchangeably on a common bar shaped mount and are illuminated by rod shaped light source 1 which projects light through the character patterns to one of the achromatic condenser lenses 11-14. Deflecting prisms 18 associated with lower case letters and identical prisms 30 associated with upper case letters are arranged to be movable into the path of light from a required character pattern by guiding rods 33 and 32 fitted to upper and lower case prisms respectively and moving in bushes 34, 35, fitted to prism carrier 19, the lower guiding rod being connected through a system of levers 36 to actuating solenoid 37. Prisms 18, 30 are movable in pairs comprising one upper and one lower case prism. A given parallel light beam is deflected via prisms 40, 41 to lens 20 which forms an intermediate image 21 at a focal point of lens 22. A parallel light beam leaving lens 22 meets turning mirror 24 movable by device 44 and is focused by objective 25 to form an image 28 in the reproduction plane 27. Lenses 20 and 22 are mounted in discs 45 and 46, which in turn are rotatably mounted on spindles 47 and 48 rotatable by motors 53 and 54. Discs 45 and 46 carry a number of lenses of differing focal lengths such that the size of the character reproduced may be varied. Reproduction plane 27 may be adjusted in relation to lens 25 to form a sharp image. Upper or lower case characters are selectable either by movement of prism 41 to select a single beam from the two leaving a moved deflecting means 18, 30 or by activation of a respective flash light attached either to the upper or lower case row of character patterns. The character carrier may alternatively take the form of a drum turnable about the light source.

Title: Process and apparatus for the production of expanded thermoplastic articles
IPC: B29C44/24
Filed: 1968-10-28
Abstract: 1,241,306. Moulding cellular articles. COMPAGNIE DE SAINT-GOBAIN. 28 Oct., 1968 [6 Dec., 1967; 15 Jan., 1968], No. 51071/68. Heading B5A. A method of obtaining moulded articles from beads of a thermoplastics material containing a blowing agent, comprises the steps of preheating the beads to soften them, introducing the preheated beads into a mould and heating the beads in the mould with superheated steam. Beads 1 are fed by gravity from a hopper 2, Fig. 1, on to a belt 3 above which is located a band conveyer 4. Hot air is introduced into one of a set of boxes 6, 7 and the opposite one of which is connected to vacuum. Superheated steam is supplied by jets 8 in box 9 below which is a box 10 connected to vacuum. The moulded slab then passes between conveyers 16, 17 which may be closer together than the conveyers 3, 4 and the slab is cooled by cold air circulating between boxes 11, 12. In another example, Fig. 6 (not shown), the hopper has two compartments containing beads of different size or density so that a layered product as shown in Fig. 7, is produced, the beads in the outer layers 65a and 65c having a higher density than those of central layer 65b. The formed sheet may be undulated by passing it between slatted conveyers. The slats may be shaped to provide egg or fruit receiving cavities in the sheet. The sheet may be transversely or longitudinally corrugated by passing it between opposed rollers or belts after heating, e.g. by infra-red lamps, if necessary. In an example, Fig. 2, for making discrete articles, beads 22 are fed by hot air from a hopper 23 into a perforated mould 18. Steam is supplied via pipes 24 to the mould jacket 19 and superheated steam is supplied to the mould cavity via pipes 26 after replacing the hopper with a cover and, if desired, the diffuser 20 with a base. The hopper may be connected to the mould by a pipe through which the beads are supplied to the mould by a hot air stream.

Title: Variable-rate data-signal receiver
IPC: H04L7/033
Filed: 1973-11-07
Abstract: 1445163 Data transmission; multi-speed systems TELECOMMUNICATIONS RADIOELECTRIQUES ET TELEPHONIQUES 7 Nov 1973 [10 Nov 1972] 51621/73 Heading H4P A synchronous data receiver operable on at least two transmission speeds related by an integer N has a speed change sensor detecting a decrease in speed. A speed increase detector may also be incorporated. The receiver comprises an N output cyclic pulse distributor 11 synchronized with a clock pulse generator 5 operating in a phase locked loop. A device 9 generates an output signal in the absence of pulses from at least one of the N outputs which are disconnected in the absence of detected transitions of received signals. N = 3 in Fig. 1 which comprises an operational amplifier 12 connected as an integrator by RC coupling 14, 15, of long time constant, feeding through threshold circuit 16 a NAND gate 9 also receiving inputs from similar circuits C2, C3. AND gates P1-P3 receive cyclic synchronous inputs from distributor 11, formed by a mod N = 3 counter 11 and stepped by a clock pulsd generator 5, phase locked with data transition detector 2, which also primes gates P1-P3. At the highest speed, integrators C1-C3 supply a continuous output to NAND 9 which gives 0 output. At change to 1/3 speed, coincidence will not occurr on two of gates, say P1, P3, between distributor output and transition pulses, hence output of C1, C3 decays, according to the characteristic of RC network 14, 15, bdlow the threshold value of 16 hence NAND 9 gives an output to circuit 10 which reverses switch 17- 19 to a corresponding lower frequency position ; switch 18 adapts the transition detector to a new rhythm and switch 19 narrows the passband of receiving circuits to reduce influence of noise. Transmitting speed may or may not be reduced in synchronism with clock 3 pulses. A second circuit detecting an increase in speed may be included and comprises a generator, comprising monostable circuits in cascade, supplying pulses at instants T/3, where T=bit rate, after positive going edges of clock pulses, so that zero crossings cannot be detected at the lower speed by analyser 22. When speed increases to higher rate, zero crossings should coincide with sampling pulses hence provide an input to integrator CL, similar to C1 &c. which provides an output to 10 which normalizes switches 17-19. In another arrangement (Fig. 6, not shown) the integrators are replaced by reversible counters which through a gate network operates in similar manner.

Title: Apparatus for steering a longwall mineral mining machine
IPC: E21C35/24
Filed: 1971-11-12
Abstract: 1376932 Mineral mining machines COAL INDUSTRY (PATENTS) Ltd 13 Oct 1972 [12 Nov 1971] 52691/71 Heading E1F [Also in Division G3] A mineral mining machine 1, having a cutter head 6, is provided with a probe 10 for sensing the rock boundary of a seam which is mounted on that part of the machine carrying the cutter head by means of an arm 11 biassed toward the seam; the machine being steered in response to signals from the probe and from a means which senses the position of the probe relative to the machine. The arrangement shown has a machine 1 mounted on an under frame 4 which has guides 5 (only one shown) engaging the upper flanges of conveyor pans 3 and the machine is steerable by hydraulic rams which cause relative pivoting between upper and lower portions of the under frame to change the cutting horizon. The probe 10 is a combined radiation emitter/detector and is mounted on an arm 11 which is in the form of a hydraulic ram; the ram including a potentiometer arrangement (20, Fig. 3, not shown) producing an output dependent on the rams extension. A control means (Fig. 3 not shown) operates the steering rams and receives, in addition to signals from the probe and arm, a reference signal (28) from a potentiometer preset in accordance with the desired seam thickness, and a signal from an inclinometer (25) which senses the inclination of the seam floor. The inclinometer is designed to produce no signal as long as the inclination of the machine remains within preset limits but outside these limits to produce a signal having a much greater effect than the other signals. The probe is shown mounted directly behind the cutting head but can be mounted over the axis of rotation of the head (Figs. 4, 5 not shown). The arm 11, instead of having a variable length as shown, can have a fixed length and be pivotally mounted to the machine with its pivotal movement providing signals of the probe's movement.

Title: Apparatus for calculating halftone screen exposures
IPC: G06G1/14
Filed: 1972-11-15
Abstract: 1384087 Calculating exposures for half-tone photographic processes PLATEMAKERS EDUCATIONAL & RESEARCH INSTITUTE 15 Nov 1972 [3 Dec 1971] 52774/72 Heading G4B  Relates to the calculation of various exposure factors for producing optimum, colour, half-tone reproductions, taking into consideration factors of the particular equipment to be used and the desired densities (density is the logarithm of opacity) of the midpoint, highlight and shadow regions of the reproduction. A device for performing the calculation includes a base 12, two slides 22 and 32 and three cursors 50, 52 and 54. The base bears a linear density scale 72 between the two slides. An opaque strip 46 bearing a logarithmic units of exposure scale 70 is releasably fastened to slide 22. A transparent plate 42 bearing a co-ordinate grid 74 is releasably fastened to slide 32. Strip 46 and plate 42 may be exchanged for similar items bearing different scales &c. for calculations relating to different equipment. The spacing of the coordinates along the axis of abscissa of grid 74 corresponds with the density scale 72. On grid 74, a first curve, representing per cent dot area versus density of original, and a second curve representing per cent BFE versus time of exposure, are inscribed. BFE is the basic flash exposure which by itself produces the minimum desired per cent dot area. The first curve is obtained by exposing a grey scale against an average density background to produce a halftone. The per cent dot area is measured for areas corresponding to areas of the scale of known densities. The second curve can be obtained by trial exposures or from the film manufacturer's template of the curve. Slide 22 is now moved to align the exposure index of the screen to be used and indicated on scale 70 with the "1À0" mark on scale 72. Next slide 32 is moved to align a predetermined point on the first curve with the chosen mid-point density on scale 72 using cursor 52. The latter then indicates the main exposure on scale 70. Cursor 54 is moved into alignment with the selected high light density on scale 72; this cursor then indicates, on the second curve, the "flash exposure", i.e. an extra exposure applied with the screen in place but no image, to improve the highlight end of the range. Cursor 52 is moved into alignment with the selected shadow density on scale 72 and where the first curve intersects an additional scale carried by this cursor is an indication of "bump exposure", i.e. an extra exposure made with the image in place but no screen, to improve the shadow end of the range. A circular form of the calculating device is described, Figs. 10 and 11 (not shown).

Title: Process and device for preparing urea
IPC: B01J3/04
Filed: 1965-12-14
Abstract: In a process for making urea from ammonia and carbon dioxide, the heat of formation of ammonium carbamate is controlled by using a heat-exchanger comprising bundles of cooling elements, each element consisting of two straight concentric pipes constructed so that the coolant is fed to the inner pipe and is discharged through the space between the inner and outer pipes, the coolant being a urea solution obtained by expansion of the hot synthesis urea solution. Using the urea solution as the coolant serves to free the solution of ammonium carbamate, which decomposes to give ammonia and carbon dioxide, and to concentrate the urea solution. It is preferred to use, as coolant, a urea solution from which a substantial portion of the ammonium carbamate has already been removed, e.g. by stripping with carbon dioxide and, subjecting the urea solution to a pressure reduction. The process and apparatus are described by reference to drawings (not shown).
