Title: Packages
IPC: B65D85/62
Filed: 1964-11-11
Abstract: A wrapper for packaging fatty compositions, e.g. butter or margarine, may be made of aluminium or polyvinyl chloride foil, polished parchment or combinations of these and is provided with a barrier which prevents exudation of the contents particularly when such packages are stacked. In one embodiment, the barrier is formed by a longitudinal groove impressed in both overlapping edge portions 61, 71. According to the invention the edge portion 71 tends to dissociate from the portion 61 outwardly of the groove so that an air lock 8 is formed which prevents liquid exuding therepast. Several parallel grooves may be provided and the groove or grooves may be formed in the edge portion 61 only. In a second embodiment, Fig. 5 (not shown), the inner or both overlapping portions are embossed with a honeycomb design 11. A third embodiment provides the inner or both overlapping portions with one or more lines of impressed printing which lines may be accompanied by one or more grooves.

Title: Polyene compounds
IPC: A23L5/47
Filed: 1967-01-27
Abstract: Novel carotenoids of the general formula in which R is hydrogen or C 1-4 alkyl and the broken line denotes an optional bond, except the all-ethylenic compound in which R is methyl, are claimed per se and a process for preparing these novel carotenoids and the allethylenic compound in which R is methyl is claimed in which 2,6,10,15,19,23-hexamethyltetracosa - 2,4,6,8,10,14,16,18,20,22 - decaen- 12 - yn - 1,24 - dial is condensed with at least two moles of a butan-2-one of the general formula Me 2 C(OR)COMe in the presence of an alkaline condensing agent and an inert solvent suitably at 40-60 C. and then optionally the triple-bond of the product is hydrogenated using palladium on calcium carbonate as catalyst deactivated with lead and quinoline and the cis-C 12-13 double bond is isomerized into a trans bond suitably with light in the presence of iodine. Intermediates.-The lithium salt of 5-(1- methoxy - 11 - methylethoxy) - 3 - methylpent- 3-en-1-yne is reacted with 3-ethoxy-2-methylaerolein in liquid ammonia to give 1-ethoxy-8- (1 - methoxy - 1 - methylethoxy) - 2,6 - dimethylocta-2,6-dien-4-yn-3-ol which is reacted with 2% sulphuric acid to yield 8-hydroxy-2,6-dimethylocta-2,6-dien-4-yn-1-al. Partial hydrogenation of this compound using a palladium on calcium carbonate catalyst deactivated with lead and quinoline, followed by cis to trans isomerization in the presence of iodine as catalyst, gives 8-hydroxy-2,6-dimethylocta-2,4,6-trien- 1-al which is reacted with phosphorus tribromide and N,N-dimethylformamide to afford 8- bromo - 2,6 - dimethylocta - 2,4,6 - trien - 1 - al. This compound is reacted with triphenyl phosphine to give 3,7-dimethyl-8-oxo-octa-2,4,6-trien- 1-yl-triphenyl phosphonium bromide, which is converted into the corresponding dimethyl acetal with methyl orthoformate and the product is reacted with 2,7-dimethylocta-2,6-dien- 4-yne-1,8-dial in the presence of sodium methoxide to give a tetramethyl acetal product which is hydrolysed with N-sulphuric acid to give 2,6,10,15,19,23 - hexamethyltetracosa - 2,4,6,8, 10,14,16,18,20,22 - decaen - 12 - yne - 1,24 - dial.

Patent ES-340254-A1 (ES)
Title: Improvements in or relating to domestic or industrial refuse incinerators
IPC: F23G5/20
Filed: 1967-05-09
Abstract: A refuse incinerator having a burner unit 19 comprises a cylindrical grid assembly 8 rotatably mounted via rollers 12 within a casing formed by two coaxial cylinders 1 and 2 spaced apart to define an annular space 3 therebetween. One of the rollers is connected to a drive motor (not shown). The grid 8 comprises an annulus of tubes 9 wherein each tube has several radial branches 14 connected together by plates (15, Fig. 2) to define a continuous longitudinally extending helicoidal path. Refuse from a hopper 18 enters through a frusto conical section 16 having vanes 17 to direct the refuse into the incinerator, unburnt refuse being rejected through a section 21 into a hopper 20, and the ash passes through the grid 8 into a box 4. An extraction fan (not shown), connected to the box 4, induces air for combustion through an adjustable air flap 24 into the space 3 where it is distributed through apertures (25, 34, Fig. 3) to the box 4 and to the grid 8 respectively. Additional air is induced through apertures 22, 23 into the tubes 9 and out through the branches 14 into the refuse bed. In an alternative embodiment shown in Fig. 5, the grid tubes 9 are joined together via perforated refractory metal elements 41. Radial blades 42 of similar material are attached to the tubes. Combustion products exit into a chimney 52 mounting an extraction fan via a chamber 50 which contains catalyst elements 51. A push-rod assembly (56, Fig. 4) forces refuse from a hopper (57) into the grid 8.

Title: Improvements in or relating to processes for the detection and evaluation of randomly-occurring electric signal pulses
IPC: H04M15/18
Filed: 1967-10-17
Abstract: Metering pulses subject to distortion on lines 11 to xy are gated to individually associated storage cores K11-Kxy by sampling pulses e (Figs. 1 and 2), these cores being interrogated by doublet pulses a, b occurring just before and just after each alternate sampling pulse e. The results of the a and b interrogations are registered separately on registers E1 and E2 for groups of lines in parallel, the registers being read out serially to produce coincident outputs a1 a2, corresponding to an a, b, interrogation for each line. The outputs al, a2, are put in a store SP by way of leads e1, e2, and are returned one scanning cycle later as signals m1 m2, for comparison with the current a1, a2, signals. The signals m1, m2, al, a2, are operated on by gates S1 and S2 so that if in the order given they exhibit the binary code 011 in the first or last three bit positions then a signal ad is generated to instruct the common metering store to add one to the corresponding subscriber's cumulative meter pulse store. An alternative process of judging the results of interrogation is illustrated in Fig. 3 where the. al, a2 signals produce a signal el for storage and production one scanning cycle later as m1 only if both a1 and a2 are binary ones. If al and a2 are binary ones and the preceeding signals al, a2, were not, i.e. m1 does not exist, then a signal ad to the common meter store is produced. The alternative process requires a faster sampling pulse rate relative to the meter pulse length than is required for the circuit shown in Fig. 1. To eliminate negative impulse interfering voltage on the metering lines diodes D11-Dxy are provided. The decision as to the presence of a pulse may be based on more than two consecutive doublet interrogations
Patent ES-350992-A1 (ES)
Title: Improvements in or relating to valves
IPC: F16K11/044
Filed: 1968-02-27
Abstract: A manually operated valve designed to control the flow of water from an inlet 3 to either an outlet 1, which has connected thereto a bath tap, or to an outlet 4, which has connected thereto a shower head, includes a valve member 23 which is formed from two resilient washers 24 and 25 retained in an H-shaped holder 26 and which is movable between two aligned and opposed seats 9 and 22. In operation, springs 33 and 42 retain the valve member in the position shown whereby the shower outlet 4 is isolated and flow from the inlet 3 to the tap outlet 1 takes place via ports 17, which ports are formed in a fixed sleeve 16 within which the valve member is slidable in a non-fluid tight manner, and seat aperture 8. Upon depressing a button 35, 38, a part 39 thereof strikes the valve closure member stem 27 and consequently moves the. closure member into engagement with seat 9 (Fig. 2, not shown). Subsequent release of the button results in only the latter being returned by spring 42 to its uppermost position, the closure member remaining in contact with seat 9 as long as the fluid pressure acting thereon exceeds the returning force exerted by spring 33 [Fig. 3, not shown). In this second position of the valve member, flow from inlet 3 to outlet 4 takes place via ports 17, aperture 21 and ports 43. The closure member can be moved out of engagement with seat 9 and in opposition to fluid pressure acting on the member by manually withdrawing the button until flanges 29 and 41 engage one another and thus, together with the upward bias of springs 33, 42, moves the closure member upwardly into engagement with seat 22. Figs. 5-7, not shown, indicate a modification whereby the trip flow rate can be reduced, whilst Figs. 8-10, not shown, indicate a further modification in which a change over from shower to tap delivery can only be achieved by reducing the pressure of water at the inlet 3.

Title: Preheating in yarn texturing
IPC: D02G1/02
Filed: 1968-05-07
Abstract: For producing crimping therein, multi-filament yarn is pulled, with the filaments substantially flat and parallel, through first contact heater means, the filaments are assembled into a twisted yarn, and the latter is pulled through second contact heater means. Untwisted multi-filament thermoplastic yarns 12, 13 pass from respective spools 10, 11 through pre-twister means 14, such as described in Specification 1007813, and are then led by pulleys 15 and a guide 16 to tensioning means 17, the yarns then passing via a pulley 19 downwards in flat, parallel formation to engagement with the surface of an arcuate groove 31 formed longitudinally in an elongated, vertically-disposed hollow body 30 heated by steam via a pipe 33. From groove 31 the yarns pass through opposed crotches of crossed rollers 81, 82 freely journalled in a fixed support 83, whereby the yarns become progressively assembled into a twisted yarn 18 which passes upwardly into engagement with the surface of a longitudinal groove 32 formed in body 30. The twisted yarn is guided by rollers 42, 43, 43 to a descending direction, the twist being set by cooling, either natural or artificial, at this stage. The crimped component yarns 12, 13 are then separated over fixed pins 61, 62 by traction from pairs of conical rollers 65, 66 and are wound on takeup rollers 73, 74. A tensioner 120 may be inserted between groove 31 and the rollers 81, 82 to increase the tension in the twisted yarn. In a modification only one multi-filament yarn is treated, the pre-twister means 14 and the separating pins 61, 62 then being omitted, and twisting means 121 being located immediately in advance of the relevant traction rollers.

The VHF oscillator which uses a transistor in common emitter amplifies the intermediate frequency (I.F.) of the UHF.
Patent ES-360751-A1 (ES)
Title: Pulse producing system
IPC: H02M7/162
Filed: 1968-11-27
Abstract: A pulse circuit for a polyphase converter comprises a 3 stage ring counter including gate turn-off type thyristor switches 66, 76, 84 (Fig. 2) which are fired in sequence to pass current pulses C, D, E (Fig. 3A) through drive transformers 58, 60, 62, from B + and via diodes 52, 54, 56 to B-, to fire the respective thyristors of the converter. In addition n timing sine wave sources 2, 3 and 1 having outputs phase displaced from each other by 360 degrees/n, are coupled to the switches by transformers 40, 46, 50 so that as each thyristor switch conducts, a timing sine wave of the same frequency as the required converter frequency is applied to a "cross-over detector" 30 via diodes 38, 44, 48 and lines 42, 74 together with a pre-set D.C. voltage level 106 (Fig. 3A) from a source 64. The detector in turn produces clock pulses therefrom to switch the ring counter. The cross-over detector 30 comprises a transistor 96 in parallel with an integrator C100, R102 between B+ and B-. When a negative going portion of a timing sine wave 2, for example, intersects the D.C. voltage level 106 (Fig. 3A) at time t 1 , the base voltage of T96 is lowered and it cuts off, whereupon its collector voltage increases, produces a spiked positive pulse 110, which has no effect on the counter. At time t 2 the waveform 2 again intersects level 106, going positive. Thus T96 conducts again, its collector voltage decreases and a negative spike clock pulse is produced across R102 and is fed via lead 28 causing the ring counter to change state by cutting-off switch 66. The consequent rise in anode voltage 66 is applied to the gate of switch 76 turning it ON. Thus the next firing pulse 114 is initiated, which continues until waveform 3 intersects the D.C. voltage level 106 going positive, when clock pulse 116 is produced to switch off 76 and turn ON 84, and so on. A resistor 104 maintains the diodes 38, 44, 48 in the forward state irrespective of the polarity of the timing sine waves. Figs. 3b, 3c (not shown) illustrate the effect of change in voltage level 106, which can produce a phase shift in the drive pulses C, D, E through a full 180 degrees. The pulse circuit Fig. 2 is for use with a 3 phase bridge converter having 3 thyristors and 3 diodes (Fig. 1, not shown). Two such circuits may be combined to control a six thyristor bridge converter, or alternatively a modified arrangement. Fig. 4 (not shown) using only one cross-over-detector with six timing wave sources and a six-stage ring counter, may be used. In this arrangement when one switching stage is cut-off the next stage will conduct current through the transformer of the cut-off stage for a further 60 degrees in addition to conducting current through its respective transformer. Thus each pulse transformer will have a pulse of width 120 degrees across it, the pulses of successive waveforms overlapping by 60 degrees as Fig. 5A (not shown). The control voltage level may be variable in dependence upon a difference between the converter output and a reference voltage.

Potentiometers 120, 120a and 145 may be provided to obtain the desired output voltage. The switching circuits comprise ONOFF transistors 116, 114 116a, 114a and 150, 152 coupled to a supply source 130 via pushbuttons 100, 102 and 110. A station is manually tuned by depressing button 110, turning transistor 150 off and turning transistor 152 on to couple the output voltage from tuning potentiometer 145 via diode 154 and resistors 65-67 to the varactors 14, 20 and 31. Diodes 156c and 156d keep transistors 114a, 114 turned off. Similarly when buttons 100 or 102 are pressed, the output voltage from the associated tuning device 112 or 112a is fed to the varactors and the voltages from the potentiometers of the other tuning devices are uncoupled from the varactors. To obtain a tuning on potentiometers 120 or 120a corresponding to that obtained in the potentiometer 145 of the manual tuning device a comparator 80 is used which includes an indicating device 85 operating when the applied voltages are unequal. An alternative embodiment (Fig. 2, not shown) has the potentiometers 120, 120a and 145 in the collector circuit of the ONOFF transistors. An alternative embodiment of the comparator (Fig. 3, not shown) has two indicating devices 85, 95 one of them lighting up when the tuning voltage from one of the tuning devices is lower or above the tuning voltage from the manual tuning device 148. The tuner 50 may have a separate B+ supply or a priority circuit including a switch 168, a capacitor 162 and resistor 164 used to connect one of the tuning devices to the varactors when the supply is just turned on. Once capacitor 162 charges up to the potential of source 130, any of the desired tuning circuits may be brought into operation by pressing the corresponding pushbutton.
