Patent ES-346062-A1 (ES)
Title: Poultry gizzard processing machine
IPC: A22C21/06
Filed: 1967-10-14
Abstract: In a machine for processing poultry gizzards, each stomach with gizzards attached after having been slit open, draped over-inside upwards-and washed as disclosed in Specification 1,196,025 on the upper run of an endless travelling chain conveyer 11 is guided by guides 17, 23 and discharged from the end of said upper run with the aid of jets of water from nozzles 33, which jets throw each opened gizzard inside downwards over a bridge 32 on a sloping shelf 29. A jet of water from a nozzle 30 is directed at the opened gizzard and under the bridge and towards portions of two counter-rotating transverse rollers provided with longitudinal ribs 24, so that the gizzard is flung inside downwards over said roller portions, which are separated by a rip 25 through which the stomach unaffected by the water jets from nozzle 33, but not the gizzard, passes. A pusher 35 actuated by a pneumatic cylinder 37 in timed relationship to the conveyer chain 11, assists in detaching the stomach from the gizzard and pushes the opened gizzard inside downwards on to the roller portions provided with interengaging helical teeth 26, which detach the lining from the interior face of the opened gizzard and deposit the cleaned open gizzard on a shoot 48, down which the gizzard slides, assisted by a jet of water from a nozzle 54, into a discharge trough 52. (For Figures see next page.)

Patent ES-353988-A1 (ES)
Title: Tube rolling mill for producing thin walled tubes
IPC: B21C37/16
Filed: 1968-05-17
Abstract: A thin tube is rolled from a blank by reducing the major part of the blank to its final thickness, while reducing the terminal part to a lesser extent. A tube having outside diameters D, and D2, Fig. 2, is thus produced. The blank is rolled on a mandrel by means of three rolls 1 which are each supported at one end in a fixed plate 4 and at the other end in an angularly adjustable plate 5. Rotation of the plate 5 by a piston cylinder assembly 11 against stops 9 and 10 varies the spacing of the rolls from, and also their angle of skew relative to, the centre line 6. The stop 9 is adjustable by being threaded into a fixed support, while the stop 10 too can be progressively adjusted during rolling to permit tapering of the blank. A photo-electric cell which detects the end of the blank immediately before it reaches the rolls, causes rotation of the plate 5 to move the rolls outwardly, thereby producing a tube with a thickened end. Each bearing, Fig. 6, for supporting one end of a roll is radially adjustable by means of a threaded piston 16 which is rotatable by a worm 19 and gear 18 within a fixed nut 20. The head of the piston is housed within a cylinder portion 15 of the bearing, pressure fluid being supplied to the cylinder such that under excessive rolling loads the bearing is able to move outwardly as a safety measure. The worms 19 of all the bearing are interconnected by gearing to provide simultaneous radial adjustment of the three rolls.

Title: Preparation of (cis-1,2-epoxypropyl)phosphonic acid and its salts and esters
IPC: C07C381/00
Filed: 1969-05-12
Abstract: (Cis-1,2-epoxypropyl)-phosphonic acid and its salts and esters are obtained by treating a formyl phosphonate, e.g. a compound in which R is a C 1 -C 5 alkyl, C 2 -C 5 alkenyl, aryl, or aralkyl radical with an ethylide which is substituted at the methylene carbon by an appropriate leaving group, i.e. a compound M#-CH#-CH 3 wherein M+ is the leaving group, e.g. a di-(C 1 -C 5 )- alkoxy phosphinyl, di-(C 1 -C 5 ) alkyl or diaryl sulphonium, tri-(C 1 -C 5 )-alkyl- (or triaryl) - ammonium, di-(C 1 -C 5 )-alkyl sulphoxonium, tri-(C 1 -C 5 )-alkyl phosphonium or triaryl phosphonium cation. The process is suitably conducted in a solvent, e.g. an ether or dimethylsulphoxide, and the ethylide reactant may be prepared in situ in the solvent and the formyl phosphonate then added to the solution. When the products are esters they may be converted to the free (cis-1,2-epoxypropyl)-phosphonic acid, e.g. by hydrolysis with a mineral acid, hydrogenolysis, or treatment with trimethylchlorosilane followed by -aqueous hydrolysis. The phosphonic acid may then be converted to a salt, e.g. an alkali metal or alkaline earth metal salt, especially the calcium or disodium salt, by treatment with an aqueous solution of an appropriate base. Diethyl sulphoxonium ethylide is obtained by reacting diethyl sulphoxide with ethyl iodide in solution at 100-110 C. to form triethylsulphoxonium iodide and then treating the latter with sodium methylsulphonyl methylide in dimethyl sulphoxide. Triethylammonium ethylide is obtained by adding tetraethylammonium bromide in ether to an ethereal solution of phenyl lithium at 25 C. and decanting the supernatant liquid. Diethylsulphonium ethylide is obtained by reacting diethyl sulphide with ethyl bromide to form triethylsulphonium bromide and then treating the latter with an equivalent of sodium methyl sulphonyl methylide in dimethylsulphoxide.

Patent ES-437780-A1 (ES)
Title: Pulse-code modulation communication system
IPC: G10L19/04
Filed: 1975-05-19
Abstract: A pulse-code modulation transmission system having reduced redundancy and high transmission quality utilizes a variable companding law and variable number of bits per sample both of which vary in accordance with the type and/or short-time volume of the signal associated with a particular talker as well as with the type and/or short-time volume of all of the signals associated with all of the talkers handled by the transmission system. The system utilizes the envelope or modulating signal for the speech signal to provide a companding law which varies as the talker varies and, for a particular talker, as the short-time volume of that talker varies, so that redundancy can be reduced without impairing transmission quality. This companding law adapts itself to the vowels, consonants and syllables of the word in accordance with their volume in order to optimize the signal to quantizing noise ratio.
Patent ES-439173-A1 (ES)
Title: Television signal processing apparatus including a transversal equalizer
IPC: H04N5/208
Filed: 1975-07-04
Abstract: Signal delaying means, included in the luminance channel of a color television receiver, are responsive to the television video signal processed in the receiver. A portion of the signal delaying means serves to equalize the time delays of signals processed in the chrominance and the luminance channels of the receiver. A plurality of differently delayed video signals are developed at signal coupling means associated with the signal delaying means. At least two of the delayed video signals, spaced apart in time by a predetermined interval inversely related to a frequency at which it is desired to relatively attenuate the video signals, are combined to determine the peaking characteristics of the luminance channel. At least one other of the delayed video signals is used to produce a signal to control the bandwidth characteristics of the luminance channel. Additional means may be provided to allow the amplitude of the output signal derived by combining the peaking and bandwidth controlling signals to be controlled so that signals processed in the luminance channel may be either peaked or depeaked, depending on the quality of the incoming video signals.
