Patent EP-0009360-A1 (EP)
Title: Manufacture of printing sleeves
Inventor: ALSOP ARTHUR GRAHAM
IPC: B41N1/20
Filed: 1979-09-10
Abstract: An all metal printing sleeve having a slight internal taper for fitting to a similarly tapered printing roll, applying air under pressure to outlets intermediate the ends of the roll to expand the sleeve slightly. The sleeve has an inner metal layer (41), e.g. of copper or zinc, and an outer electro-plated metal layer (42), e.g. of copper. The inner layer may be sprayed in molten form onto a forming mandrel (38) having a slight taper and provided with a release coating (39). The sleeve may be removed from the forming mandrel by applying air under pressure to outlet holes (22) in the mandrel. A sprayed-on first layer may be transferred from the forming mandrel to a plating mandrel by heating the sleeve to expand it slightly (fig. 6 - not shown).

Abstract: A steering gear and a method of assembling such a gear. A rotatable rack bar (1) having helical rack teeth (5) is displaceable along axis (2) by rotation of a pinion. The end of the bar-(1) is connected to a tie rod (6) having a ball end (7) forming a universal joint in housing (8). A skirt (14) of the housing (8) encloses a roller thrust bearing (9) to which it is secured by peening or rolling a hem part (14a) of the skirt over an outer race member (17) of the thrust bearing. A thrust plate (15) is interposed between a plug (12) and the thrust bearing (9). Upon deformation of the hem part (14a) to clamp the thrust bearing to the housing (8), the plug (12) is displaced into its bore against the ball end (7) to provide desired preloading for the ball joint. The inner race member (19) is secured to a shaft part (20) of the rack bar (1). I

Abstract: La teneur en vitamine B12 (cobalamine) du sang humain et des tissus mammiferes est habituellement controlee en utilisant les techniques de titrage par dilution radioisotopique (RIDA). La presence de "sub stances analogues" a la vitamine B 12 dans de tels echantillons, les dites substances analogues ayant ete analysees par erreur comme etant veritablement de la vitamine B12 en utilisant les techniques RIDA de l'art anterieur, a ete determinee. De telles erreurs sont dues au fait que des proteines de liaison utilisees communement dans les techniques RIDA de l'art anterieur comprennent normalement des proteines qui lient a la fois la vraie vitamine B12 et les substances analogues a la vitamine B12 anterieurement non reconnues. Les erreurs dues aux substances analogues a la vitamine B12 sont evitees en utilisant une composition de liaison de la vitamine B12 qui est substantiellement exempte de substances qui lient les substances analogues a la vitamine B12. De plus, en utilisant les deux types de liants dans des essais separes, on peut determiner la quantite de substances analogues presentes en faisant la difference des essais.

Abstract: The invention relates to a device for determining local absorption differences in a planar object section, comprising an X-ray source (2) and an X-ray detector (10) which is directed towards the X-ray source and which comprises a number of plate-shaped collimating elements (30) which are directed towards the X-ray source. On the respective lines of projection of these collimating elements towards the source, there are arranged radiation absorbing elements (34) whose dimensions, measured in the direction ofthe X-ray source, are smaller than those of the collimating elements and whose dimensions measured in a direction at right angles and in the sectional plane are larger than those of the collimating elements. Apparent variations in the sensitivity of the X-ray detector due to a lateral shift of the X-ray focus in the X-ray source, are thus substantially mitigated.

Abstract: In a gas turbine engine, the main air flow path leads through a compressor (14), a recuperative heat exchanger (24), a combustor (20), where fuel is injected and bumt, a turbine (16), which drives the compressor (14), and then back through the heat exchanger (24). A small portion of the air is diverted through a conduit (32) to the nozzle (28) through which the fuel is injected; this air serves to atomise the fuel. The conduit (32) leads through a boost compressor system (12), which, if the air pressure available for atomisation of the fuel would otherwise be inadequate, raises the pressure of the air supplied to the nozzle (28).

Filed: 1980-11-14
Abstract: The system employs an evaporable liquid, such as water, and a gas which is not liquefiable within the operating temperature and pressure ranges, such as air. Hot water from source 10 is supplied by pump 16 through valve 18 to evaporator 12 where it is sprayed into air supplied by pump 23 through valve 24. The resulting increase in pressure or volume drives prime mover 14 (turbine or reciprocating piston engine) which in turn drives generator 15. The control device 36 receives inputs from sensors and controls valves 18 and 24 to achieve saturation in the evaporator 12. If the water consists of salt water, fresh water is derived as a condensation product from the prime mover.

Abstract: A coating is applied to a microporous support in the presence of a volatile liquid capable of drawing the coating into the support and of desolvating the coating. The liquid is thereafter volatilized with the resulting dry ultrafiltration membrane being essentially crack-free and having desirable mechanical and chemical stability. The support may be pretreated with a volatile liquid, such as acetone, prior to the applying of the coating to the support. Alternately,the coating material can be dispersed in a volatile liquid, such as methanol, to form a coating suspension that is applied to the support. The coating material, prefetably zirconia, will have a particle size within the range of from about 5 mµ to about 10µ. with the coating having a thickness of up to about 20µ. The support, such as a porous carbon tube, will have a pore volume of about 5-60% and a pore size of about 5 mµ-40µ. Stability is enhanced by firing the membrane at 25°C-1500°C, preferably at about 400°C-600°C.

Abstract: Circuit arrangement for obtaining a clocked signal (E) which signals pulses (A1, A2, A3) of a predetermined signal (A) which occur during the clocked periods of successive clock pulses (T). Using a first bistable flip flop (K1), an output signal (C) is generated which assumes a first binary value whenever a pulse of the predetermined signal (A) occurs, and which assumes a second binary value when no pulse of the predetermined signal occurs during a clock pulse (T). The output signal (C) and the clock pulses (T) are supplied to a second flip flop (K2) which outputs via an output the clocked signal (E) which signals the binary values of the output signal (C) which coincide with the clock pulses. <IMAGE>

Abstract: Frequency processing is carried out for radio transmitting and receiving appts. using a receive oscillator and a phase-locked-loop (PLL) transmit oscillator, which forms a mixing frequency out of the receive oscillator frequency and that of a v.c.o. of the PLL transmit oscillator. The mixing frequency is compared for frequency and phase with a comparison frequency, supplied by a quartz oscillator. The comparison forms a control criterion for the voltage controlled oscillator. The coarse tuning of the transmit frequency (fs) is obtained by dividing the mixing (fM) in stages of integral numbers. The fine tuning is obtained by changing the comparison frequency (fV) by a frequency value small in the ratio to the mixing frequency. A given formula applies to the transmit frequency using an integral dividing ratio.
